City-academe collaboration for eco-innovation and plastic-free cities
In partnership with the Iloilo City government, Department of Trade and Industry, Department of Environment and Natural Resources, and barangay (community) officials, Central Philippine University (CPU) has introduced circular economy models in 13 pilot communities to reduce plastic waste across the value chain – from sustainable consumption, production and management of plastics, as well as their alternatives.
Collaborative efforts between the public sector and educational institutes have prevented the leakage of 305 metric tonnes per month of plastic waste into the environment. Beyond the positive environmental impacts, this project has also resulted in an increased awareness within the community and stakeholders on the issue of plastic pollution and advanced knowledge of the ‘3Rs’ – Reduce, Reuse and Recycle. This impact has been especially significant amongst households, who feel empowered to be a part of the solution to addressing plastic pollution in their community – no matter how small their contribution might be.
Furthermore, the 13 pilot barangays were provided with equipment, such as motorcycles with a sidecar and push carts, which make waste and plastic collection more expedient and efficient. Collected recyclables were sold to a partner junk shop, with the revenue from sales then being used to pay the allowances of participating individuals and the material recovery facility manager.
This circular economy model has not only mitigated the environmental impacts of plastic pollution but has also empowered the communities of waste collectors and waste facility managers helping to implement the project. Furthermore, as the recycling system becomes more efficient, incentives are raised for the recycling chain actors to practice circular practices.


300 words Character sketch of Chubukov from The Proposal
Chubukov is an interesting literary character that many readers have found fascinating to analyze. In this character sketch of Chubukov, we explore his unique personality traits, motivations, strengths, and weaknesses.
Character sketch of Chubukov
In Anton Chekhov’s one-act play “The Proposal,” a variety of characters exhibit peculiarities and eccentricities. Among them is Ivan Vassilevitch Lomov’s companion, Stepan Stepanovitch Chubukov. In the play, retired landowner Chubukov is portrayed as cynical, opportunistic, and manipulative.
Throughout the play, Chubukov exhibits cunning and avarice, particularly with regard to property and money. To protect his own financial interests, he frequently tries to persuade Lomov to marry his daughter, Natalya. Chubukov’s overbearing character is likewise apparent when he intrudes on Lomov’s recommendations to his little girl, demanding his own agreements.
The character of Chubukov brings a laugh to the play despite his clever and dishonest ways. He is depicted as a ranting clown, continuously paying special attention to his own advantages and showing little worry for other people. His collaborations with Lomov are especially entertaining, as he switches among adulation and dangers to get what he needs.
However, Chubukov’s character is not without flaws. His oppressive nature and absence of sympathy towards others lead to strain and struggle in the play. Consequently, his actions toward Natalya and Lomov only serve to exacerbate their already difficult relationship.
Chubukov’s personality in “The proposal ” is a complicated blend of advantage, crafty, and humor. His true nature is revealed through his interactions with other characters, who portray him as a self-centered and manipulative individual. The character of Chubukov adds depth and dimension to the play despite his flaws, demonstrating the often absurd nature of human relationships and motivations.

Providence Cancer Institute’s “global-first” breakthrough in eradicating cancer
In this Talk:
- Dr. Tran’s breakthrough research, known as T-cell receptor (TCR) gene therapy, performs a T-cell receptor transplant which has shown to increase the effectiveness of fighting some cancers. Dr. Tran’s lab at the Providence Cancer Institute
in Portland, Oregon, was the first in the world to use this therapy to treat pancreatic cancer.
- Dr. Tran’s adoptive cell therapy, a form of immunotherapy cancer research, is based on the theory that the immune system is capable of curing cancer. A small number of T cells in the body are able to recognize and eliminate virus infected cells.
Some T cells with a certain receptor can recognize cancer cells and target their own cancer cells.
- Adoptive cell therapy removes T cells from a cancerous tumor and amplifies them to fight cancerous cells and re-infuse the T cells into the body. T cells targeting cancer mutations likely mediated the curative responses.
- Dr. Tran reviews numerous case studies from clinical trials with immunotherapy and adoptive cell therapy highlighting the success of immunotherapy cancer treatment and what was learned.

The Webster-Hayne Debate. Bitter sectional disputes emerged during the presidency of Andrew Jackson: the issues that divided north from south, and sometimes east from west, included the disposal of public lands in the west, the power of the Second Bank of the United States, and the ability of the national government to pass heavy tariffs (taxes on imported goods) to protect northern industries rather then simply to raise revenues. Southern politicians hoped to support the Westerners' desire for cheap lands in exchange for their support in lowering the tariff. John C. Calhoun (see John C. Calhoun and John C. Calhoun), who was still Vice President, had anonymously written an essay in support of the idea of nullification in 1828, claiming that South Carolina had a right to nullify the hated tax within its boundaries. In January 1830, South Carolina's ablest orator, Senator Robert Hayne (see Robert Y. Hayne), invited the west and the south to unite in support of the principles of states' rights and nullification; Massachusetts Senator Daniel Webster replied in support of the union in one of the most celebrated debates in American History.

Comet Assay: DNA Damage / Repair Detection
Comet assay, also known as single cell gel electrophoresis, is a sensitive technique for measuring DNA damage in single cells and has become well known in the field of toxicology and drug discovery. The Comet assay can detect specific DNA damage and repair, and thus can explore mechanism and mode of action to further investigate the effects of a compound.
The theory is that undamaged DNA retains a highly organized association with matrix proteins in the nucleus and when the DNA is damaged (by chemicals or UV radiation), this organization is disrupted. During the application of an electric field, the individual strands of DNA lose their compact structure and drift out of the nucleus and into the low melting point agarose suspension. The DNA (which has an overall negative charge) it is drawn towards the positively charged anode. The undamaged DNA does not move, whereas the damaged DNA (smaller fragments) are free to migrate away from the nucleus. Simply put, the amount of DNA which leaves the nucleus is a measure of the amount of DNA damage to the cell. The brighter and longer the DNA tail, the higher the level of damage.
The Comet Assay can be used to detect DNA damage caused by double strand breaks, single strand breaks, alkali labile sites, oxidative base damage, and DNA cross-linking with DNA or protein. The Comet Assay is also used to monitor DNA repair by living cells.
Untreated human cells run on Comet Chip.

Analysis of Factors in Influencing the Learning Effect for Higher Vocational Students
- 10.2991/assehr.k.200401.073How to use a DOI?
- learning effect, constructivism, instructional design, learning campus culture
In the process of teaching in higher vocational education, there are many factors that can influence students’ learning effect. Through the observation, investigation and interview for several teaching cycles, it is found that in addition to some important subjective factors of teachers and students, lots of objective factors such as the training objectives of professional talents, curriculum setting, campus atmosphere, teaching environment and instructional design should not be ignored either. In particular, the stable and professional teaching site, reasonable instructional design and learning campus culture will have a greater impact on students’ learning effect. In order to cultivate high-quality and high-skilled talents, higher vocational colleges need to mobilize all forces to help teaching within the visible and touchable range of students.

Editor’s Note: Miriam Kingsberg, an assistant professor of history at the University of Colorado-Boulder, reflects on her new book Moral Nation: Modern Japan and Narcotics in Global History (University of California Press, 2013).
Describe your book in terms your bartender could understand.
The book is about the history of narcotics in Japan from the mid-nineteenth century (when the country opened after more than two centuries of seclusion) through the mid-1950s (when Japan regained its independence after war and occupation by the United States). The central question I ask is: how do narcotics become entangled with nation and empire-building agendas during this century? I argue that the Japanese stance on drugs became a platform to enter an ongoing global conversation about standards for political legitimacy in nations and empires in the late nineteenth and early twentieth century.
What do you think a bunch of alcohol and drug historians might find particularly interesting about your book?
I am an historian, so I did write the book from a history background and for a history audience. And the book is a chronological narration of these three episodes of moral crusade, and how the persons and institutions involved in them used narcotics to assert social power and produce certain national and imperial outcomes.
But one thing I would also want to stress is that it derives a lot from interdisciplinary scholarship and methodologies that would be traditionally considered outside of history. For instance, I used a fair amount of quantitative methodology. Japan, for various reasons, collected more and better statistics on narcotics than any other power in the world at the time. That data was not necessarily meant to be used in the way that I used it, but my argument certainly derives from the data. My chapters are also organized according to the concept of “moral entrepreneurship,” which comes out of sociology. I would hope that, in addition to historians, I am talking to scholars in other fields as well.


Exploring The Role Of Orthopedic Trauma Devices In Sports Injury Rehabilitation
The integration of advanced technologies has further enhanced Orthopedic Trauma Devices. Computer-assisted navigation systems, for example, provide real-time feedback to surgeons, enabling more accurate placement of implants and reducing surgical errors. Minimally invasive techniques, aided by smaller and more specialized instruments, have resulted in shorter recovery times, reduced scarring, and decreased post-operative pain for patients. Furthermore, the introduction of innovative devices, such as locking plates and intramedullary nails, has revolutionized the treatment of fractures.
These devices offer improved fixation and stability, allowing for earlier weight-bearing and faster rehabilitation. External fixators have also seen advancements, with the development of modular systems that provide greater flexibility and adjustability in managing complex fractures. The use of Orthopedic Trauma Devices has not only enhanced patient care but also transformed the overall treatment approach to musculoskeletal injuries. These devices have revolutionized the field by providing surgeons with more reliable and effective tools to address a wide range of injuries, including fractures, dislocations, and complex trauma cases.

The newest TechStars curriculum by technology education provider Computer Explorers is Minecraft: Desert Island Survival. In the course, students ages 8 and up will be fully engaged as they work collaboratively on a private server The newest TechStars curriculum by technology education provider Computer Explorers is Minecraft: Desert Island Survival. In the course, students ages 8 and up will be fully engaged as they work collaboratively on a private server to build and expand upon a 3D immersive world exclusively designed for Computer Explorers.
“Minecraft is an open-ended tool that can be used to effectively integrate technology into the classroom. Current thought is that nearly 80% of future careers will require some science, technology, engineering and math (STEM) skills. Every possible means must be used to cultivate the interest of our youth in these fields. We believe Minecraft: Desert Island Survival is an effective means,” says Computer Explorers Curriculum and Program Development Director Elizabeth Marion.
Students will work in Survival Mode which requires them to take into account resources, hunger, tools and more. They have to explore in order to collect resources and process what they find, such as smelting ore to create metal. As they develop their world, the students gain insight into the various elements of survival, settlement and exploration in a way that keeps them constantly observing, hypothesizing and testing. “Our course fully engages students while promoting individual creativity and building teamwork skills,” says Marion.
Minecraft: Desert Island Survival aligns well with the National Educational Technology Standards for Students(NETS-S) by creating original works as a means of a personal group expression, using models or simulations to explore complex systems and issues, promoting communication and collaboration with project teams, and allowing students to plan and manage activities to develop a solution.


The phylum Arthropoda is by far the largest in the animal kingdom, accounting for about 90% of all species. The one characterization of arthropods is the external stiff cuticle known as an exoskeleton. The exoskeleton is comprised of proteins and chitin which is sometimes mineralized with calcium carbonate. It is arranged in segments which are then joined by more flexible tissue which allows for movement.
Arthropods are said to be the most successful group of animals on the planet This is due to the fact that there are arthropods inhabiting and even colonizing most types of terrain and subterranean habitats. There are insects abundant in the skies and crustaceans inhabiting the seas. Arthropods vary in size from the smallest of mites to the giant King Crabs of the sea.
The phylum is further divided into four classes, insecta, arachnida, myriapoda and crustacea with the insects forming the majority of species in the phylum Arthropoda.
Insects have three distinct body segments, three pairs of legs and one pair of antennae and often the adult form of many species can have wings, either one or two pair. Arachnids on the other hand only have two distinct body segments and have four pairs of legs and do not have antennae or wings. Myriapoda have many pairs of legs and many body segments, never less than nine. They have one pair of antennae and never have wings. Crustaceans have several to many pairs of legs but not less than four pair, they have two pair of antennae, never have wings and the body segment count is variable but never three.

The Summer Solstice marks the beginning of Summer on a day usually between June 19th - 25th in the Northern Hemisphere. Also known as Litha or Midsummer, the longest day of the year allows us to fully celebrate the gift of Light. Now that Summer is among us, we must enjoy all the illumination, life & growth, that the Sun provides for us. In witnessing the longest day of the year, we also experience the shortest night of the year & with this we can embrace the light that outweighs the darkness. Pagan cultures often view this as a time to celebrate the full pregnancy of the Goddess & the virility of the Sun God, as He has now reached his peak strength. As the Sun appears to stand still in the sky, we can look to find the balance between Sky & Earth, Fire & Water. By holding a bonfire ritual near a body of water, we invoke an energy that dwells within us, bringing passion & fury, calmness & motion, God & Goddess. Although some can view this time as a battle between light & dark, one can use this time to find the balance within themselves. We can enjoy this new season to get back out in nature, enjoy our communities, friends, family & hobbies, as Summer truly brings a magick all on it's own.


In the 3 rd century AD the river Rhine once again became the northern border of the Roman Empire. The “Limes” on the right bank of the river was dropped and the castellum “Bodobrica” was built around 350 AD on the left bank. This fortress was surrounded by a wall – 8 m high and 3 m thick with 28 towers. Its size of 308 m x 154 m provided enough space for 600 legionaries.
South of the castellum the Roman military road went through the Rhine valley. Throughout the castellum went a main road that still could be find as the Oberstraße (now pedestrian area).
Position of the Römerburg in the Roman castle
After the departure of the Roman forces in 405 AD the walls of the castellum were used as the city walls of the medieval town of Boppard until the 12 th century.
The northern wall where you can find our restaurant nowadays was broken down when building the church of St Severus. This Roman wall became unnecessary because a new wall was built nearer to the river Rhine.
The city of Boppard was pawned by emporer Henry VII to the archbishop of Trier Balduin in the 14th century. He errected a larger city fortification that surrounded the new residential areas in the east and the west by using parts of the Roman castellum walls. So only the southern wall of the castellum belonged as an outer wall to the medieval town fortification.
Archbishop Balduin also extended the castle keep (donjon or large tower) that once was built by Richard of Cornwall to a stronghold now known as the „Alte Burg“ (old castle or electoral castle).


Faster than a scalpel-wielding hand, able to snake to hard-to-reach surgical sites in a single bound—future surgeons will be super surgeons, all thanks to robotics.
Alistair Fleming, VP Medical at Sagentia
In many industries, the advance of robotics has created worries about robots supplanting humans. But in the world of surgery, the next generation of robotics is set to do the opposite—to supercharge the surgeon and put him in control as never before.
First generation systemsIntuitive Surgical’s da Vinci system defined the first generation of general surgical robotics. It promised a revolution in surgery and is today used for hundreds of thousands of procedures annually. The da Vinci System “is powered by robotic technology that allows the surgeon’s hand movements to be translated into smaller, precise movements of tiny instruments inside the patient’s body,” according to the company. The surgeon is provided with a high-definition, 3D window on the operative world through a laparoscope also operated by one of the robot’s arms. Characteristics of first-generation robotic surgery systems include the large size and physical dominance of the operating room, the placing of the surgeon into a console outside the sterile field, and surgeons receiving feedback limited mostly to visual cues on-screen.
The invisible man
The effect of this “fly-by-wire” surgery has in part been to abstract the surgeon from his traditional role at the heart of the operating room. Once in the middle of the team, he is now pushed to the margins of the room, almost invisible at his console, controlling the operation remotely (indeed the system was originally designed with a completely physically remote battlefield use in mind). New breeds of robotic surgical systems aim to change this, and they will have fundamentally different characteristics from the first generation.

Norman Rockwell was enormously important as a guide to the American way of life. He saw the poetry, beauty and sadness of everyday life and he shared his view with others through his Saturday Evening Post magazine illustrations. Teaching young students about influential artists from history is much more fun when the lesson gets the students involved, excited and thinking about the artist’s life, hobbies, family and more.
Step 1 – Introducing the Master
In an interactive assembly, students are introduced to Norman Rockwell while background music from the 1900s plays. With thought provoking questions and stories of his early life, they learn that he paid great attention to details while painting familiar, everyday scenes. He looked at the world around him and painted what he saw with truth and humor and made people feel his artwork was a part of their own lives. The students hear that he was terrible at sports but good at art. He always wanted to be an artist and his friend told him to “shoot for the stars.” Rockwell’s dream job was to be an illustrator for the most popular magazine of that time, The Saturday Evening Post, so he gathered his courage and painted two sample magazine covers. He got the job! But he still had to work hard and persevere to come up with new, fresh ideas for each cover. He finished over 300 covers for The Post and worked for them for about 50 years.
Step 2 – Learning from the Master
Besides the cover art itself, students learn that an illustrator must also pay attention to other information that is part of the overall design of a magazine cover, like the headlines, the name, price and date. An important task of an illustrator is to work out the best arrangement of the artwork, lettering, and graphics, putting these elements together to create a layout. Students use grid worksheets to practice lettering and layouts in preparation for their final project. Meet the Masters students get to become illustrators and design their own magazine cover layout.
Step 3 – Working with the Master
After practicing and preparing, the students are ready to design their own layout and create their magazine cover. Using graph paper, oil pastels and markers, they design the cover art, create the lettering, the headline, and the date. The format varies slightly for the various age groups: beginning, intermediate and advanced, but they central design is theirs to create.

The aim of this paper is to study the contribution of Jean-Jacques Rousseau's works to the sociological analysis of social coordination, i.e., how people succeed in organizing themselves to act in concert. Rousseau focuses his attention on mankind, and more precisely the human being as shaped by nature and the human being as part of society. He tries to understand what motivates him to act, or could make him act. However, to this theoretical position, which is the precursor to later developments in the sociology of action, he adds an essential proposition: social coordination can only take place on an infra-rational base which binds people by means of feelings of sociability. Although natural, these loving passions are by no means spontaneous. They must be sustained and protected by some devices that embody the symbolic mediation between men. Thus with a view to proving that the unity of society is rooted in the "heart," apart from any calculated interest, Rousseau studied the dimension of human existence that is social belonging. In this connection he formulated a complex set of hypotheses and analyses in order to transcend the most firmly rooted dualisms: nature versus culture, individual versus society, being versus appearance, and reason versus passion. Rousseau attempted to construct a kind of synthesis between what the nature of man as a free being demands and what his condition as a social being requires. This analysis opens the way to a "structural individualism" in sociology, i.e., a theoretical approach that is attentive to the individual, to his autonomy and his motives as much as to the infra-rational social and symbolic conditions of his cognitive activity and actions.

Hydroponics is a method of growing plants without soil. Instead, it uses a nutrient-rich solution that flows directly to the roots. Hydroponic systems are becoming more and more popular because they allow for year-round growing, faster growth rates, and the ability to grow plants in areas where soil is not available or conducive to plant growth. Here are some tips to help you get started with hydroponic planting.
Selecting the Right System
There are various hydroponic systems available, including drip systems, ebb and flow systems, and deep water culture systems. Choose a hydroponic system that fits your needs and budget. Make sure to research the system thoroughly before purchasing to ensure it is the right one for you.
Choosing Your Plants
Not all plants thrive in hydroponic systems. Choose plants that are suited for hydroponic growing, such as lettuce, herbs, and tomatoes. Avoid plants that require a lot of space, like pumpkins or watermelons.
Prepping Your System
Before planting, make sure your hydroponic system is properly set up and working. Fill the reservoir with water and add the necessary nutrients. Adjust the pH level to the recommended range for your plants. Once your system is set up, let it run for a few days to ensure everything is working properly.
Planting Your Seeds or Seedlings
Start by planting your seeds or seedlings in a propagation tray. Once they have sprouted, transfer them to your hydroponic system. Make sure the root system is fully submerged in the nutrient solution. If you are using a drip system, make sure the water drips directly onto the root system.
Maintaining Your Hydroponic System
Regular maintenance is key to a successful hydroponic system. Check the water level daily and add more as needed. Test the pH and nutrient levels weekly and adjust as needed. Keep an eye out for any signs of disease or pests, and take action immediately.
Hydroponic planting can be a fun and rewarding way to grow your own plants. By selecting the right system, choosing the right plants, prepping your system, planting your seeds or seedlings, and maintaining your hydroponic system, you can grow healthy and vibrant plants all year round. Happy planting!

LOS ANGELES -- Many parents encourage their kids to take part in team sports, thinking they'll get their recommended daily activity. But a new study suggests that children who play sports might not get enough daily exercise, and teens may get even less.
The study, released this week in the journal Archives of Pediatrics & Adolescent Medicine, looked at how much exercise 200 kids age 7 to 14 got while playing team soccer, baseball or softball. The children wore accelerometers that tracked movement and intensity during team practice time, which ranged from 40 to 130 minutes for soccer and 35 to 217 minutes for baseball and softball.
Researchers discovered that among all participants, only 24 percent got the recommended 60 minutes of physical activity during practices. The news for teens was even worse -- only 10 percent of children age 11 to 14 reached that amount. All participants averaged about 45 minutes of moderate to vigorous activity.
The sports, chosen for their popularity and different activity levels, did show disparities. Soccer players were active for an average of 13.7 minutes more than those who played baseball or softball.
Boys outdid girls during practice, spending on average 10.7 more minutes being active. And both boys and girls were inactive for an average of 30 minutes per practice.
In the study, the authors wrote, "The health effects of youth sports could be improved by adopting policies and practices that ensure youth obtain sufficient physical activity during practices: emphasizing participation over competition, sponsoring teams for all skill levels across all ages, ensuring access by lower-income youth with sliding scales for fees, increasing practice frequency, extending short seasons, using pedometers or accelerometers to monitor physical activity periodically during practices, providing coaches strategies to increase physical activity, and supporting youth and parents in obtaining adequate physical activity on nonpractice days."

Valles Caldera National Preserve is planning an prescribed burn between Oct. 11 and Nov. 30. Photo Courtesy NPS
VALLES CALDERA NEWS RELEASE
The National Park Service (NPS) is planning a prescribed fire in the southwest corner of Valles Caldera National Preserve later this fall to reduce hazardous fuels, improve wildlife habitat, and create healthier and more resilient ecosystems. Fire managers with the preserve aim to take advantage of expected favorable conditions, including fuel moisture levels, air quality, and forecasted weather.
The prescribed burn, planned between October 11 and November 30, 2021, includes 338 acres in the Southwest Banco Bonito area, adjacent to New Mexico State Route 4 near mile marker 30. A final decision on whether to proceed with a specific prescribed burn depends on multiple factors, including the national wildland fire preparedness level, resource availability, fuel moisture levels, air quality, and forecasted weather. The NPS also will take a risk-informed approach to managing prescribed fire during the COVID-19 pandemic.
Prescribed fire is part of a science-based framework for managing ponderosa pine and dry mixed-conifer forests to reduce the risk of high severity wildfire and allow low intensity fire to play its natural and beneficial role in this frequent-fire ecosystem. Each prescribed burn is designed to meet specific objectives and will be managed with firefighter and public safety as the highest priority.
The NPS manages prescribed fires in compliance with New Mexico state regulations on air quality and smoke management. Smoke-sensitive individuals and people with respiratory problems or heart disease are encouraged to take precautionary measures. Information on air quality and protecting your health can be found at the New Mexico Department of Health Environmental Public Health Tracking website (nmtracking.org).

Lightweight beryllium alloy connectors are used throughout the electrical systems of cars and trucks for their reliability and to improve vehicle fuel efficiency. Copper beryllium components are found in traction controls, transmissions, electric motors, anti-lock braking and fuel injection systems. Further, copper beryllium electrical connectors are used in electrically assisted steering systems that are replacing older, heavier hydraulic and electromechanical systems.
In commercial aircraft, landing gear bushings and bearings made from copper beryllium handle great compressive and wear forces despite corrosive atmospheres and exposure to wide ranges of temperature. The higher strength of copper beryllium compared to alternative bronze landing gear materials allows the bearings to be made smaller and lighter. These weight savings, in turn, make planes more fuel efficient which results in reduced exhaust emissions.
Beryllium is a crucial component of the electronic safety and navigation technology, including Global Positioning Systems (GPS) used for air-traffic control and air route surveillance.


Paleontologists discover 'Scotty,' the world's largest T. rex fossil: 'The rex of rexes'
Paleontologists have unearthed the largest Tyrannosaurus rex fossil ever discovered, researchers say.
The massive predator, nicknamed “Scotty,” was about 42 feet long and likely weighed more than 9.7 tons, according to the study published last week in the peer-reviewed journal The Anatomical Record. Not only is the massive specimen the biggest T. rex ever found, it’s also larger than all other carnivorous dinosaurs.
“This is the rex of rexes,” said study author W. Scott Persons in a news release. “There is considerable size variability among Tyrannosaurus. Some individuals were lankier than others and some were more robust. Scotty exemplifies the robust.”
The fossil was nicknamed after a celebratory bottle of scotch opened the night it was discovered in Canada. Although the bones were found in 1991, it took more than a decade to excavate them from the surrounding hard sandstone.

Scotty died at around 28 years old in Saskatchewan about 66 million years ago, the study says. Most T. rexes grew fast and died young, making Scotty the oldest of its kind.
“You can get an idea of how old a dinosaur is by cutting into its bones and studying its growth patterns. Scotty is all old growth,” Persons said. “By Tyrannosaurus standards, it had an unusually long life. And it was a violent one.”
Scotty’s bones bear the scars of numerous injuries including a broken rib, an infected jaw and a bite that appears to be from another T. rex on its tail.
The skeleton, which is about 65 percent complete, is scheduled to go on display in May at the Royal Saskatchewan Museum.

Naufragios or shipwrecks were calamitous events in the 250-year history of the line. Their disastrous impact was felt more in the western end of the line—in the Philippines. The present study seeks to understand why and how these disasters occurred. To answer these questions, the frequency, geographic distribution and causes of shipwrecks involving Manila galleons were examined in order to understand the interplay of various hazards along the Manila-Acapulco route. The study reveals that 90 percent of these disasters occurred in the western portion of the line—the Philippines, Japan and the Marianas—70 percent of which occurred within Philippine coasts and archipelagic waters. Marine hazards dot the entire stretch of the Manila galleon route from Cavite to San Bernardino with every step in the way being associated with a lost galleon. Along the archipelagic route, the San Bernardino Strait accounted for most of the wrecked galleons. Most, if not all, incidents of shipwrecks were attended by severe weather condition. However, the severe punishments inflicted on galleon officers and government officials involved in shipwreck incidents emphasised the human factor in the occurrence of maritime disasters. Generally, the Manila-Acapulco line operated under favourable winds and sea conditions until it reached the western end of the line underscoring the need for more stringent safety measures navigating these waters where weather, topography and human error combined to create catastrophic ending for many of the Manila galleons.
Efren B. Isorena obtained his BA, MA and PhD in History from the University of the Philippines. His graduate studies deals with Philippine prehistory and maritime history. He held teaching positions at the University of the Philippines (Diliman and Manila campuses), De La Salle University, St. Scholastica’s College in Manila and the Assumption College in Makati. He is currently an Assistant Professor at the Ateneo de Manila University teaching undergraduate and graduate courses. The author has published a number of articles on Philippine prehistory and maritime history both in local and international journals.

Recommendations & Best Practices
Build Data Storage Schemas That Store Numeric Tweet ID and User ID: User messages require action to be taken on all Tweets from that User. Therefore, since all compliance messages are delivered only by numeric ID, it is important to design storage schemas that maintain the relationship between Tweet and User based on numeric IDs. Data consumers will need to monitor compliance events by both Tweet ID and User ID and be able to update the local data store appropriately.
Build Schemas That Address All Compliance Statuses: Depending on how compliance activities will be addressed in various applications, it may be required to add other metadata to the data store. For instance, data consumers may decide to add metadata to an existing database to facilitate restricting the display of content in countries affected by a status_withheld message.
Handling Retweet Deletes: Retweets are a special kind of Tweet where the original message is nested in an object within the Retweet. In this case, there are two Tweet IDs referenced in a Retweet – the ID for the Retweet, and the ID for the original message (included in the nested object). When an original message is deleted, a Tweet delete message is issued for the original ID. Tweet deletion events typically trigger delete events for all Retweets. However, in some cases not all are sent and client systems should be tolerant of incomplete Retweet deletions. The deletion of the original ID should be sufficient to delete all subsequent Retweets. It is a best practice to reference the original Tweet ID when storing Retweets, and deleting all referenced Retweets when receiving Tweet delete events.


THE EXPRESS TIMES — MARCH 29, 2012 — The Pennsylvania Department of Environmental Protection this afternoon said officials were notified a horse from Lower Saucon Township had to be euthanized because it was suffering from the virus, which is spread by the bite of an infected mosquito.
Officials did not have the exact location or the date of the euthanization, but said it was likely done by a veterinarian after testing on the animal indicated an infection.
DEP spokesman Kevin Sunday said the unseasonably warm weather probably played a factor in the early arrival. “Obviously it’s been a very warm winter and mosquitoes like warmth,” he said.
Mosquitoes get infected with the West Nile virus by feeding on infected birds. The infected mosquitoes then spread the virus by biting humans and other animals such as horses.
The DEP usually starts full-time monitoring and testing of mosquitoes in April.
According to the National Weather Service, the average temperature this March in the Allentown area was 50.2 degrees. Historically, the average for the month is 39.8 degrees in the area; this February’s average temperature of 36.6 degrees was also about 5 degrees warmer than the historical average, the weather service reports.
Other parts of the country also are experiencing a higher risk of West Nile virus because of the unseasonable warm temperatures. On Thursday, Kentucky’s agriculture commissioner warned that the weather could make horses more vulnerable to infection. Health officials in West Virginia expressed similar concerns last week.
Sunday, from the DEP, said factors other than temperature could also be at play. Wet weather plays a role in part because mosquitoes lay eggs in standing water, he said.
The department spokesman said he’s hopeful the case in Lower Saucon Township will serve as a reminder that people should avoid keeping tires, buckets and other items that collect standing water outdoors. He also said the case is an example of why livestock owners should vaccinate their animals against the West Nile Virus.
According to a statement from the DEP, collection and testing of dead birds begins May 1 and can be reported on www.westnile.state.pa.us or by calling 717-346-8238. In Warren County, call the county mosquito commission at 908-453-3585.


In 1955 24-hour race at Le Mans the Mercedes-Benz racing team demonstrated a sensational new braking device. All tree Mercedes-Benz SLR cars entered by Daimler-Benz and driven by Moss/Fangio, Kling/Simon and Levegh/Fitch were fitted with the airbrake operating like an airplane’s landing flaps, helped slow the cars down from 150 mph to safe cornering speeds in a matter of seconds. The gadget, subject of much stormy discussion, supplemented the cars’ regular pedal-operated brakes, thus reducing dangerous “fade” caused by overheating. Unfortunately that was the year Pierre Levegh crashed one into a grandstand. The resulting fire and casualties cause Mercedes to withdraw from Le Mans and shut down their racing program for decades. Later that year the airbrake was tested on F1 car. Moss drove the streamlined W196 with the airbrake at Monza. The scale model was issued by Brumm in Moss’ commemorative “722” series that reproduce the cars he piloted. The race number 722 made famous by its victory at the 1955 Mille Miglia.

Despite outliving the Ice Age, the Hundsheim rhinoceros rapidly disappeared without any effective changes to its environment, becoming foe to two more specialised and less ecologically-diverse rhino species that monopolized the food supply in particular climates. German researchers at the Senckenberg Research Institute and the University of Hamburg have explained why, after almost a million years of survival through testing conditions, the Hundsheim rhinoceros (Stephanorhinus hundsheimensis) suddenly disappeared.
By examining the dental fossils of the rhino, the team were able to identify an extremely diverse dietary spectrum and tolerance to differing ecological conditions, allowing the species to survive harsh conditions, such as the Ice Age, by dominating forests and open plains. Yet approximately half a million years ago, two new, highly specialised rhinoceros species developed during periods of extended cold and hot periods. The anatomical characteristics of these novel types (Stephanorhinus hemitoechus and Stephanorhinus kirchbergensis) suggest that they were better able to process and consume steppe and forest nutrition respectively, introducing unprecedented competition, with entirely different feeding strategies, for the Hundsheim rhino.
Despite being attributed with the broadest tolerance to vegetation of any known species, living or extinct, the study indicates that this non-specialised tolerance was fundamental to Hundsheim rhino's extinction, despite a generally benign (or even favourable) ecology and without interference by early humans.
The results are published in the Quaternary Science Reviews .

Halitosis is chronic bad breath and it can’t be solved by using mouthwash or eating breath mints. Halitosis can remain for a long period of time and can sometimes be a sign of a serious problem. So what causes halitosis? We’ll break it down for you.
Cavities and gum disease allow bacteria to get stuck in more crevices within your mouth. These dental problems make it more difficult to clean your teeth and mouth. It’s important to go to regular dental check-ups to make sure you don’t have any cavities and to manage gum disease.
Sinus infections cause mucus to drip from your nose, into your mouth, and down your throat. Bacteria thrives on mucus making your breath very unpleasant.
Saliva is a natural way to combat halitosis because it breaks down bacteria in your mouth. But if your body isn’t producing much saliva, it can cause halitosis. Try chewing sugarless gum to produce more saliva.
Halitosis can also be caused by more serious health problems such as gastric reflux, diabetes, liver, or kidney disease. Be sure to go to your general doctor for regular check-ups.


There are two types of cholesterol. HDL cholesterol is “good” cholesterol and helps support your body’s functions while not raising your risk of cardiovascular disease. LDL, or “bad” cholesterol, raises your risk of cardiovascular disease.
Saturated fats, like those in coconut oil, red meats, and dairy, can raise your LDL and lower your HDL. Unsaturated fats, especially polyunsaturated fatty acids, do the opposite. They can be found in avocados, nuts, and some oils such as olive oil. Trans fats are never good for you and should be avoided entirely. They have been found to be a major cause of cardiovascular disease. They can still be found in some processed baked goods.
There are two major causes of high cholesterol: poor diet and sedentary lifestyle, and genetics. The best way to know what your risk is to have your blood checked! If your cholesterol is high, there are some things you can do to lower your risk.
- Get some exercise. Find a fun way to get your steps, like going for a walk with your family, have a dance party in your kitchen, create a steps challenge on Virgin Pulse.
- Find a way to get more unsaturated fats in your diet and lower your saturated fat intake. Avocados, lean meats, and olive oil are easy and yummy choices.
- Increase your fiber intake by incorporating raspberries, dark colored vegetables like beets, carrots, and broccoli, and stock your pantry with beans.
- If you have genetically high cholesterol, and lifestyle changes don’t help, your doctor may prescribe medication to help.
By making small changes, you can make big changes in your risk of heart disease and get down with cholesterol.


Topic: Recent National Natural Landmark Designations at Nottingham Serpentine Barrens and Ice Mountain
Speaker: Katia Engelhardt, Research Associate Professor, University of MD, Appalachian Laboratory
National Natural Landmarks are considered the best examples of a geological and/or biological feature within a biophysical province. Designation encourages the preservation of these features. Dr. Engelhardt has been evaluating potential National Natural Landmarks for the National Park Service since 2007 and has developed evaluation reports that have led to the designation of Nottingham Serpentine Barrens (Chester County, PA), Ice Mountain (Hampshire County, WV), and, most recently, Albany Pine Bush (Albany County, NY). Dr. Engelhardt will summarize the National Natural Landmarks Program and then describe some of the features that have led to the designation of the sites, including rare and endemic plant species.
This free program will begin immediately following a brief MNPS chapter business meeting. The public is welcome to attend.

Mixed Media Abstract Art
What is Mixed Media Abstract Art?
If you’re looking for a truly creative art piece, mixed media abstract art is an excellent choice. This form of artwork combines different types of mediums such as paint, clay, photographs, and more to create something with a unique texture and visual appeal. Read on to learn more about what mixed media abstract art is and how it can add a unique component to your home.
A collage assemblage is made by gluing different paper clippings and photographs onto canvas to create a varied look. Other materials like stones, beads, and even scraps of clothing can be added, giving this creative art piece a ton of depth and dimension. Different methods are used to create this type of art including gluing, painting, nailing, and even welding certain objects to the piece. This mixed media abstract art serves as both a painting and a sculpture in one.
Mixed Media Painting
There are a few different ways that an artist may design a mixed media painting. By experimenting with canvas, different paints, and a variety of techniques, the artist can create a truly unique and creative art piece. A mixture of paints such as oil and acrylic, spray paint, and watercolors can all be used together in one painting. Other materials like coffee can add another component and depth of color. The artist may utilize several techniques including dry brushing, stenciling, and traditional painting with a brush.
Sculpting allows an artist more freedom to create something abstract and dramatic. A mixed media sculpture can have a clay base, but it will also include a myriad of other mediums like glass, wood, cloth, and items found in nature. The process involves connecting these items together, but the artist may also crochet, embroider, or carve other components, too. A mixed media sculpture can include everything from integrated LED lights to ornaments.


A roughly 2,000-year-old underground city in southeastern Turkey believed to be the largest of its kind ever discovered may have been a refuge for early Christians fleeing Roman persecution, according to researchers.
The complex was initially unearthed in 2020 and is located in the Midyat district of Mardin province, according to Live Science.
Researchers believe the site may have housed up to 70,000 people and was initially built as a “hiding place or escape area” more than 1,900 years ago.
The underground complex was reportedly discovered during a local cleaning and conservation effort. It is believed to possibly be the largest such complex in the world, according to The Jerusalem Post.
Researchers say only 3% of the site has been excavated, so it’s still unknown how large the entire city may span.
Gani Tarkan, who headed the excavation effort and serves as director of the Mardin Museum, told Live Science the complex includes a tunnel over 100 yards long and nearly 50 chambers, including what appeared to be dwelling spaces, water wells and places of worship.
“Families and groups who accepted Christianity generally took shelter in underground cities to escape the persecution of Rome or formed an underground city,” Tarkan was quoted as saying. “Possibly, the underground city of Midyat was one of the living spaces built for this purpose.”
“It is an area where we estimate that at least 60-70,000 people lived underground,” he added.
The worship spaces included an apparent Christian church and a Jewish synagogue with a large hall featuring a Star of David symbol on one of its walls.
Historical artifacts and other decorations were also recovered from the complex, including Roman-era coins and oil lamps similar to those described in the Gospels, indicating the underground city may have been built as early as the second century, according to Tarkan.


Nosebleeds are common in children and adults. They occur when the membranes that line the nasal passages dry out. The blood vessels burst, causing a bloody nose. This is most common during the winter, when cold, dry air irritates the nasal membranes. In adults, blood thinners, elevated heart rates, and elevated blood pressure worsen bleeding. In children, most nosebleeds are cauterized in the office, with local anesthesia, while the child is sitting on their parent’s lap.
In adults, many nosebleeds are cauterized in the office with chemical or electrocautery. Patients are taken to the operating room for more serious nosebleeds. Dr. Rosner has had high success rates stopping noses from bleeding in the operating room by using sinus endoscopes to cauterize or clip the main blood vessels going into the nose (sphenopalatine artery ligation).
Types of Nosebleeds
There are two types of bloody noses, classified according to whether the bleeding is coming from the front or the back of the nose. The majority of nose bleeds begin in the lower portion of the septum, and are often marked by a flow of blood from just one nostril. These are characterized as anterior nosebleeds and are easily treatable. Posterior nosebleeds begin high and deep within the nose and flow down the back of the mouth and throat. This rare form of nosebleed is considered serious and requires immediate medical attention. It is most common in the elderly, those with high blood pressure, and in people who have experienced trauma to the nose or face.
To stop a nosebleed at home:
Place Afrin nasal spray on a cotton ball, then place the Afrin soaked cotton ball in the nose, pinch and hold the soft part of the nose while sitting up straight and leaning forward slightly. If you cannot get the bleeding to stop in 15 minutes, then seek the care of a doctor.


We’re big fans of Science in Ms Cregan’s 3rd class so for the month of March we explored the force of friction. Friction is a force we experience every day, all day. We can’t see it. So, we tend not to notice it.
Friction is a force between two surfaces that are sliding, or trying to slide across one another, for example when you try to push a toy car along the floor.
The children worked to construct a marble maze using a range of different materials such as cotton wool, gravel, cloth and even dry glue! Their target was to create a maze that would slow the marble down as much as possible. We knew that rougher surfaces would create more friction with the marble as it is a smooth object made of glass.
Each group planned their maze together, discussing layout and design. They then drew a blueprint before starting construction.
When all mazes were completed we had 3 test runs which we timed. Some of the groups made changes to their maze after the test runs when they noticed that certain materials did not have enough friction with the marble.
After some adjustments and alterations, the children then completed a final marble run using a timer. All groups did a fantastic job making such creative and unusual mazes!
Why not try this fun experiment at home to see how friction works in other ways!

This farm is situated on Lake Hofdavatn in the Hofdastond County, District Skagafjordur. It was a church site and a parsonage for a time.
The first settler, Hofdi-Thordur Bjarnason, lived there. His great grandson was Thorfinnur Thordarson, who was among the first European settlers in North America in the early 11th century. He and his wife, Gudridur, had the son Snorri during their short stay there. The family moved back to Iceland and lived at the farm Glaumbaer in Skagafiord after their return.
A grave with the earthly remains of five men was discovered just south of River Hofdaa in 1952. They showed signs of a battle or an execution and can probably be traced back to a battle between the Icelanders and English traders or fishermen in 1431.
Lake Hofdavatn is the largest lake of the Skagafiord district, 10 km², just east of the Thordur Promontory. To the north and south the lake is separated from the sea by low gravel isthmuses and it abounds with trout and char. Plans for a large harbour for large freighters and fishing vessels were made, but were never realized.

Happiness is considered very important in life. Why is it difficult to define? What factors are important in achieving happiness? You should give reasons for your answer using your own ideas and experience.
It has been observed that cheerfulness is an integral part of our life. However, it seems a herculean task to express it. Out of many reasons, the prominent one is that it is a state of mind. There are many factors that people can consider to obtain happiness, such as a positive outlook, pursuing one’s favourite activities.
To begin with, joy is difficult to define because it is a state of mind. To elaborate, people act differently to each other about a thing. It depends on their perception. Healthy minds always have a positive outlook for anything, which may be, in reality, is not their cup of tea. But with courage, confidence, they do not get depressed and always remain in a state of ecstasy. For instance, a glass that is filled with some water is considered half glass of water, but for others, it is full. Therefore, it depends on the perspective of the masses, how they perceive anything. Moreover, some masses are not emotionally balanced, so they get fail to express their contentment. They just can feel it and show it by wearing some kind gesture such as a smile.
On the other hand, there are many ways to get it. Firstly, developing a positive outlook can work wonders. If people think positive and avoid negativity; then, there are higher chances of getting success. A pessimistic outlook can make people only depressed, and they would not try to be satisfied with their lot. Resultantly, they will do overthinking, and this overthinking will become a root cause of their discontented life. To exemplify it, many people, after getting failed in any job interview or exam, stop doing efforts to obtain their goals. Hence, they make lame excuses and curse their destiny. At the same time, the others who do not quit and their continued efforts bring the reward for them in the end.
To conclude, thus, it is apparent that although it is hard to express happiness due to the perception of people who is widely different from each other, it can be achieved by inculcating optimism for anything, which may be hard to get. Continuous attempts make a person winner and fill his/her heart with everlasting joy.

The introduction of the reflective material
Reflective material was first introduced back in the 1930's for use on stop signs and asphalt and by the 1980’s, had evolved into silver piping on sneakers and backpacks. The reflective material is created with tiny spherical glass beads (1/2 the size of a human hair). Made from optical-grade glass, these perfect microscopic spheres are coated on one side with aluminum and then organized aluminum-side down and adhered to the material to create a reflective surface. The process allows light to bounce directly back to its source. No matter what angle the light strikes the material, the wearer is illuminated and seen.
That means that when the light from a car's headlight shines onto the strip, almost 100% of the light will reflect off and go directly back to the source. There's no diffusion, no waste, all the light bounces back to the driver.
Soon after, it was seen in high-end jackets, running gear, biking equipment, and professional safety uniforms. Although more and more industries and manufacturers were beginning to use it, reflective material stayed the same skinny cord or patch of silver material it always was.
In recent years, there have been several incidents of sanitation workers being hit. According to the analysis of accident investigation, it is found that accidents occur at night or in the early morning hours. Besides the driver's illegal operation, the clothes of sanitation workers are dark and undetectable, which is also the cause of the accident. For this reason, sanitation workers wear the reflective vest, providing a lifeline for their safety protection.
The sanitation worker changed into a mesh reflective vest. This kind of net eye vest is orange-red, by the net eye cloth that breathes air is made, before and after all stick to having 3 PVC to reflect a light lattice, have the function of warning to reflect a light, more conspicuous than the original thick and wide sanitation overalls, lighter and smaller. The materials used on the reflective vest are small lens balls, which can be returned by the original road when the light hits them. It makes it easy for the driver of the vehicle to find the wearer and avoid danger. It is usually worn by traffic police or sanitation workers and road construction workers.


The Monty Hall problem is a classic brain teaser based on a television quiz show.
The puzzle involves three doors; behind one of them is a car. The other two doors conceal goats.
The aim of the puzzle is to maximize your chances of selecting the door leading to the car.
- You select one of three doors, which remains closed for now.
- The quiz host opens one of the other two doors, revealing a goat.
- You are now given the choice to switch your selection to the other closed door.
- PROBLEM: Statistically, should you stay or switch; or does it even matter?
Contrary to what most people logically expect, you are more likely to reveal the car if you switch.
Most people initally believe that the choice does not matter. Since there are two doors left, one would expect the odds of the car being behind any of the two doors to be 50/50.
In fact, switching your choice to the other door gives you a 2/3 chance to select the car, effectively doubling your odds.
A good way to understand the solution is to consider the two original unchosen doors as one single choice. The first choice results in one of the other possibilities being outed as revealing a goat. Thus the player effectively has the opportunity to choose the entire contents of two doors, if one switches from the first choice. This is illustrated below.

"After standing in boiling water for an hour, examine the contents of the flask."
I had a pretty good idea what was wrong with the sentence but, at the time I couldn't figure out how to revise it, and the author didn't tell me.
From: How to write and Illustrate a Scientific Paper (2nd ed.) Bjorn Gustavii.
No one knows how to write a scientific paper without practice and help. Many science students practice this skill when they are asked to write lab reports. This guide will describe some best practices for scientific writing and give you some additional sources to explore.
If you have read scientific papers, you will have noticed that a standard format is frequently used. This format allows a researcher to present information clearly and concisely. Scientists communicate new ideas by publishing their research in a specialized format called the journal article.
This form usually includes 6 parts:
1) abstract (a summary of the article)
2) introduction (a brief review of why they chose this experiment)
3) materials and methods (what organisms and equipment were used)
4) results (what was found)
5) discussion (what it means)
6) references (the list of journal articles and books that the scientist referred to in the paper).


Difference Between Magnetic Resonance of MRI MRA and MRV
Your primary care doctor suggested it for magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), or for magnetic resonance venography (MRV) of your head. These techniques use a magnetic field, radio waves and a PC to create point-to-point images, which our group of master doctors can use to recognize solid tissue from diseased tissue. The MRA and MRV are explicitly intended to examine your veins.
Magnetic resonance imaging, MRI
The general term for most MRI scans. For this situation, the specialist mentioned that a scan of the whole head should be done to look for any irregularity in the whole.
Magnetic resonance angiography, MRA
MRA represents magnetic resonance angiography. It is a particular type of MRI test that allows doctors to take a look at the courses, without seeing all the tissues that line it. It may be necessary to infuse a different material, depending on the specific vessels being examined.

Magnetic resonance venography, MRV
MRV represents magnetic resonance venography. It is a particular type of magnetic resonance imaging that scans the veins without the underlying tissues being obvious. This test will usually require an injection of a different material to improve the perception of the veins.
There are several types of MRI scanners on the market with varying skills and qualifications. Familiarize yourself with our best high-field MRI machines and our recognized radiology group.

Sitorai Mohi-hosa means “Star like a Moon”. The countryside residence of the last Emir of Bukhara is named as Sitorai Mohi-hosa. Currently, the museum of the arts and crafts is operating here.
In the middle of the 19th century, Nasrullahan decided to build a new palace. To select the coolest place, the architects resorted to the well-proven method. They spread the carcasses of sheep on the possible construction sites. And in the end, they chose the place, where the meat was rotten last. Unfortunately, the first palace was not preserved.
After several decades, Emir Mir Sayid Alimhan constructed new beautiful palace and named it after his wife Sitora. Architects from Bukhara, who visited Russia, could combine western discretion and oriental color. But it also collapsed over the time.
New complex in the European style was constructed in 1918. It is divided into male and female part. However, interior of the place has oriental character.
White Hall has special value as prominent Shirin Muradov headed finishing works. All rooms were decorated with carved ganch. At the same time, ornaments are various and not repeated. There are many Venetian and Japanese glasses in unusual frames. Unusual trellis creates a reflection, which is repeated 40 times.
In the palace, there are expositions of the finest Chinese and Japanese porcelain of 14-20th centuries, the magnificent decorations of famous Bukhara jewelers, gold panels and horsecloth.
The hauz (pond) was preserved in the courtyard, where wives and concubines of the Emir bathed. Peacocks still walk in the garden of the residence. It is said that they once protected gates to the paradise. But they overlooked Satan and they were dispelled to the Earth. Since then, the plaintive cry of birds express their anguish and request back to Eden.


Folks, there are some orgs out there who are doing real good work, like the Advancement Project, the Brennan Center for Justice, and SKDKnickerbocker, they really have their boots on the ground when it comes to talking about Voting.
Their key messages really are spot on, and highlight the importance of voting, and why you should vote. Here’s the list, I figure we should post something, now and then…
- Strengthen Our Community: Voting brings us together as Americans, and you should join your family and friends to help strengthen our community.
- Equality: Voting is the one time we are all equal — whether you’re young or old, rich or poor. When we vote, we all have the same say.
- Civic Duty: As American citizens, it is our responsibility and civic duty to vote and it’s something we do to show our country and children that we are proud to be American.
- Free, Fair and Accessible: As the leading democracy of the world, the U.S. should work to keep our voting system free, fair, and accessible to all Americans.
- Have Your Voice Heard: In order to participate in our great democracy and have your voice heard, every voter needs to understand the rules in their state, register on time, and show up at the correct polling place.
- Empowerment: Voting is empowering and provides us with some control over what happens to our families and our community.
- Your Vote Counts: Your vote makes a difference, and together Americans’ voices count. If you don’t vote, you can’t complain.
And folks – don’t forget to check out all of the organizations doing good work on this issue.

Musical ciphers have been used by Western composers for centuries. They are a means of transforming text (usually a name) into a musical motif using logical relations between letters and pitches.
Since Western notation uses letters for pitch-names, the most obvious method is to map each letter onto its corresponding (or parallel) pitch. However, this only works for the letters A to G, as Western notation only uses the pitch-names A to G. As a result, composers have had to find workarounds to accommodate for other letters.
For example, in one piece, the Romantic-era composer Robert Schumann created a melody out of his wife Clara's name, transforming the letters into the musical pitches C(#)BAG(#)A. For the letters c and a, Schumann used the logical pitches C(#) and A. For the letters l and r, he simply assigned the pitches B and G(#), as they make melodic sense of the surrounding pitches.
Clarallel builds upon this method used by Schumann. In addition to the letters A to G, some other letters have default and logical corresponding pitches: k, x and q map onto C; and i and y map onto E. From this, the algorithm assigns the resulting letters to the pitches that will result in the most beautiful melody. Furthermore, all instances of a letter in a name will have the same corresponding pitch. For example, Clarallel converts the name Hannah to the pitches GABBAG. Here, h and n consistently map onto G and B respectively.
The short harmonised melodies that Clarallel generates can be used as the starting points for more complex compositions. For example, this is a short piece I wrote using the melody generated for the name Lewis Jones.


A Greek city among the top 8 ancient sites for stargazing
Many iconic ancient observing places, such as Stonehenge (England), Chichén Itzá (Mexico), or the Mesopotamian ziggurats (Middle East) are either closed to visitors at night or under vanished urban skies. But plenty of places remain where you can explore ancient sites and the night sky. The young science of archaeoastronomy studies archaeological sites in relation to the sky, whereas ancient stargazers used celestial figures and the movements of the sun and moon to keep track of time for their ritual and agricultural purposes.
National Geographic chose the top 8 ancient sites for stargazing and among them is a Greek city. In the 3rd place we find Meteora, which as cited in the article, means “in the heavens above.” Located near Kalambáka, it’s an amazing place to appreciate the stars as they have been viewed by thousands of monks who have lived here since the 11th century.
See the top 8 sites:
1.Chaco Canyon, New Mexico
2.Almendres Cromlech, Portugal
This could be a scene out of science fiction—insanely isolated monasteries on top of giant natural rock pillars. Meteora means “in the heavens above.” Located near Kalambáka, it’s an amazing place to appreciate the stars as they have been viewed by thousands of monks who have lived here since the 11th century.

The New Yorker, August 30, 1976 P. 34
A REPORTER AT LARGE about living conditions in the space station. Skylab. Skylab, built by NASA, was launched from Cape Kennedy on May 14, 1973 and the third and final crew to live there departed on February 8, 1974. Sky lab is 120' long, weighs almost 200 thousand pounds, and was built from salvaged Apollo parts. Describes Skylab'd interior in detail. Discusses the effect of weightlessness on the astronauts. Initially, the Skylab astronauts lost weight, calcium and blood volume which caused loss of water and a reduction of the manufacture of red blood cells, but after a few weeks their physical conditions returned the approximately preflight levels. Captain Charles Conrad, Jr., Commander Joseph Kerwin, and Commander Paul Weitz were the members of the first crew, and Captain Alan Bean, Owen Garriott, and Major Jack R. Lousma were the members of the second crew. The third crew, Edward G. Gibson, Lt. Col. Gerald Carr, and Lt. Col. William Pogue, arrived on Nov. 16, 1973, spent the longest time in the station, and experienced more difficulties than the previous crews. The problem lay with Mission Control, in Houston, which started them off at too fast a pace and gave them too many experiments to perform. There were 4 main varieties to experiments; solar observation, earth resources, medicine, and corollaries. In addition, each astronaut exercised daily on a bicycle ergometer. Describes daily activities of astronauts and some of the experiments performed.


What do you mean by Noise in given Dataset and How can you remove Noise in Dataset?
Noise is unwanted data items, features or records which don’t help in explaining the feature itself, or the relationship between feature & target. Noise often causes the algorithms to miss out patterns in the data. Noisy data is meaningless data. The term has been used as a synonym for corrupt data. However, its meaning include any data that cannot be understood and interpreted correctly by machines, such as unstructured text. Any data which has been received, stored, or changed in such a manner that it cannot be read or used by the program can be described as noisy data.
Methods to detect and remove Noise in Dataset
1. K-fold validation
In this method, we can look at the cross-validation score of each fold and analyze the folds which have poor CV scores, what are the common attributes of records having poor scores, etc.
2. Manual method
In this method, we can evaluate CV of each record (predicted vs. actual) and filter/analyze the records having a poor CV score. This will help us in analyzing why this is happening in the first place.
3. Density-based anomaly detection
This method assumes normal data points occur around a dense neighborhood and abnormalities are far away.
4. Clustering-based anomaly detection
Using clustering technique, we can analyze the clusters to analyze which has noise. Data instances falling outside the clusters can be noticeable as anomalies. i.e. k-Means clustering.
5. SVM-based anomaly detection
This technique uses Support Vector Machine to learn the soft boundary in the training set and tune on validation set to identify anomalies. In this approach, the need of large samples by the previous approach is reduced by using Support Vector Machine while maintaining the high quality of clustering-based anomaly detection methods. i.e. One-class SVM.
6. Autoencoder-based anomaly detection
Auto-encoders are used in deep learning for unsupervised learning, we can use them for anomaly detection to identify noisy data-set. These methods are advanced and outperforms traditional anomaly detection methods. i.e. Variational Autoencoder based Anomaly Detection using Reconstruction Probability.

As we are in the year 2002, the concept of a “networked global health” society is progressively becoming a reality. Technology barriers to connectivity, storage, and interfaces are fading while planet-wide networks are rapidly developing. The explosion of health and biomedical information, such as that produced by the unlocking of the human genetic code, can be counter-balanced by the availability of distributed and generally accessible knowledge banks. The need both for disease prevention and for continuity of care for chronic disease, coupled with severe economic pressures, has pushed various health sectors to collaborate to find optimal solutions, often crossing international boundaries.
Developments in Health Informatics are accordingly progressing at great speed. As a consequence, there is a need for a broad overview of the field. This book, with an international collection of papers, provides and updated perspective on medical informatics in the new era. Bringing together scientific papers by top medical informatics researchers from around the world, this collection provides a broad overview of medical informatics for researchers and students in health related areas as well as for those in computer science, cognitive science and biomedical informatics. This book will also be of interest to clinicians, nurses and other health care professionals, as well as to health educators and administrators. Because health care workers are increasingly dealing with information systems to support patient care, research, education, and the assessment of the quality and character of care, this book can serve as an overview of the rapidly developing field of technology in global health care.
The volume is organized into seventeen chapters covering topics such as human-computer interaction, information management, decision support, hospital information systems, imaging, bioinformatics,education and training, security and confidentiality, and evaluation. The topics and issues span all practical and theoretical, as well as empirical, aspects of medical informatics in global health


Your dentist is your biggest ally when it comes to good oral health. Regular dental visits keep your gums and teeth strong and give your dentist a chance to learn about your overall health.
In the early teens, wisdom teeth usually come in – completing the set of permanent teeth. It is important to continue regular dental check-ups throughout the teen years to ensure good oral health well into adulthood. As a parent or legal guardian, you play an important role by setting good oral health habits and making sure your teen gets regular dental check-ups. The Medi‑Cal Dental Program provides the following free or low-cost services for teens:
- Dental exams (every 6 months)
- Fluoride varnish (every 6 months)
- Molar sealants
- Teeth cleaning (every 6 months)
- Orthodontics (braces) for those who qualify
- Root canals
- Partial and full dentures
- Scaling and root planing
- Tooth removal
- Emergency services
- Outpatient services
- Sedation (if medically necessary)
*Crowns on molars or premolars (back teeth) may be covered in some cases.
During this time, the dentist may recommend new services like deeper cleanings or braces. To help keep your teen’s teeth both clean and strong, encourage healthy routines. The sugar in foods, like fast food and soda, can cause cavities and erode tooth enamel. Keeping a travel‑size toothbrush in a locker or backpack to brush after meals can also help reduce the risk of cavities and keep teeth bright (a boost to any teen’s self-esteem).

Epidermolysis bullosa (EB) is a group of hereditary skin diseases, or genodermatoses, characterized by the formation of severe, chronic blisters with painful and life-threatening complications. Despite the previous and ongoing progress in the field, there are still no effective causative treatments for EB. The treatment is limited to relieving symptoms, which—depending on disease severity—may involve skin (blisters, poorly healing wounds caused by the slightest mechanical stimuli, contractures, scarring, pseudosyndactyly) and internal organ abnormalities (esophageal, pyloric, or duodenal atresia; renal failure; and hematopoietic abnormalities). The last decade saw a series of important discoveries that paved the way for new treatment methods, including gene therapy, bone marrow transplantation, cell therapy (allogenic fibroblasts, mesenchymal stem cells [MSCs], and clinical use of induced pluripotent stem cells. Tissue engineering experts are attempting to develop skin-like structures that can facilitate the process of healing to promote skin reconstruction in injuries that are currently incurable. However, this is incredibly challenging, due to the complex structure and the many functions of the skin. Below, we characterize EB and present its potential treatment methods. Despite the cure for EB being still out of reach, recent data from animal models and initial clinical trials in humans have raised patients’, clinicians’, and researchers’ expectations. Consequently, modifying the course of the disease and improving the quality of life have become possible. Moreover, the conclusions drawn based on EB treatment may considerably improve the treatment of other genetic diseases.

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 1969
Born: 3 March 1895, Oslo, Norway
Died: 31 January 1973, Oslo, Norway
Affiliation at the time of the award: University of Oslo, Oslo, Norway
Prize motivation: “for having developed and applied dynamic models for the analysis of economic processes”
Prize share: 1/2
Ragnar Frisch was born in Oslo, the son of a goldsmith, and he trained as a smith apprentice. His mother thought he should attend the university, and they chose economics as a subject because it seemed the shortest and easiest. After graduating in 1919, he studied economics and mathematics abroad for several years. He received his doctor’s degree in mathematical statistics in Oslo in 1926 and later became a professor. He married twice and had one daughter. Frisch’s hobby was beekeeping, something he described as an obsession.
Ragnar Frisch, along with Jan Tinbergen, pioneered development of mathematical formulations of economics. He coined the term econometrics for studies in which he used statistical methods to describe economic systems. He is best known for his contributions to dynamic economic modeling, and in 1933 he presented the first mathematical economic model that could describe fluctuations in the business cycle. His later work concerned models for economic planning.

The story of the first electronic computer in Hungary
Keywords:computing history, computers and education, Hungarian scholars
After several preparatory activities in the early 50s, the Hungarian Academy of Sciences decided that it is necessary to have an electronic computer in Hungary. The Research Group for Cybernetics was established in mid-1956 and charged with the task of obtaining one. As commercial solutions proved to be impossible at that time it was decided to build the clone of a recently developed Soviet computer. The M-3 was a medium sized member of one of the first families of Soviet computers. Complete documentation and a package of key components were received in the framework of scientific cooperation. (Similar clones were built in Tallinn, Beijing, Erevan and M-3 was later manufactured in Minsk) Building of the M-3 started late 1957 (with the author's participation). Some life-signs were emerging in 1959, while more-or-less stabile operation was reached in 1960. Several improvements were made over the original design. Magnetic drum memory was exported to Timisoara for MECIPT. Despite its low performance, M-3 was successfully used to solve many real-life problems both for scientific-engineering calculations and in mathematical economics. Applications in other fields, like linguistics started too. The most important contribution of M-3 was its role in educating computer experts: many of the future leading personalities - both on the development and on the application side - got acquainted with computing around the M-3. M-3 served academic computing until 1965, extended with three more years at Szeged University. In the first part of the 60s commercial computers started to arrive to Hungary both from the USSR and the West.


John James Audubon filled his artwork with birds and plant life. Look closer: they also contain insects. Drawn life-size, the Audubon prints on view at the Jule Collins Smith Museum of Fine Art feature tiny bugs that tell us amazing details about the bird’s environment. How many insects can you find?
You can make a firefly using the art of paper folding — origami (aw-ruh-gaa-mee). In traditional origami, artists fold a single paper square into a sculpture without cutting, gluing, taping or marking the paper. Electricity powers the firefly. The energy travels along a copper tape path – a circuit – from the battery to the light. You can make the firefly blink on and off by breaking the flow along the circuit.
What You’ll Need
3V lithium battery
Part 1: Origami Firefly Construction
Part 2: Build the Paper Circuit
Fold your wings. As the copper tape on the right-wing touches the battery, your light should glow. Your firefly and the circuit are complete.

Surprisingly, I am not the only one on the Internet trying to set things straight in terms of American grammar and usage. And as I have written before, it’s terribly easy to mistake one word for another in English!.
In terms of then and than, how can you remember which is which?
Easy! Link “then” with “when.” They are both about time, and they rhyme.
So if you’re not intending to write about time, you must be making a comparison of some sort and you need to use “than.”
When will she arrive? Then she will arrive.
My dog is smaller than yours is.
This winter is colder than last year’s.
When spring comes, then winter will end.
And in the example above, the meaning really changes depending on which word you use.
I’d rather be hugged, then eaten.
(Hugs first, then I’m lunch?)
I’d rather be hugged than eaten.
(Yes, I would too.)
One last tip: if you know you constantly goof up on a pair of words (your / you’re, for example), use your computer to help you see what you might be missing. Do a search for one of the words, and read what you’ve written carefully. Is the right word in that sentence? If not, it must be the other one.


Even though it has been around for more than 100 years, geothermal energy has not been able to breakthrough its niche and become a significant part of the conversation around energy and our energy future.
With recent advances in new technologies and innovations and commitments to developing low-carbon sources of energy, geothermal is coming back into the picture hot.
And it’s hot because, well, it is the energy derived from the heat contained below the earth’s crust. And the new technologies have been developed to help extract this heat from the earth’s core and turn it into something we can use to power our homes and cities.
If you want a quick primer on geothermal, its hotspots, and how it’s used, check out this article.
On this episode, host Scott Crockatt explores the renaissance of geothermal with John Redfern, President and CEO of Eavor Technologies, an Alberta based geothermal company.
You’ll hear a little bit about the historical slow growth of the industry to date, why there is renewed support of this energy source, and how new technologies, like Eavor’s Eavor-Loop, are making huge advances in scaling and economically providing a new energy source to our energy mix and driving down emissions.
In this episode:
- Uses for geothermal
- Growth of geothermal (and the barriers)
- State of the technology today
- Geothermal use in Alberta
- Potential of geothermal in North America
- Inside the Eavor-Loop and its potential in Alberta
- Alberta, 10 years from now
About The Energy Evolution
This limited series explores the technologies, future fuels, collaborations, and more that are at the core of today’s energy evolution and how Alberta can lead the charge to a low-carbon world.

A flying boat – level 1
An unusual race happens in France last week. Athletes use flying boats. The flying boat is a boat where you lay down and pedal at the same time.
The idea is not new. Two French professors think of a flying boat in 2013. Nicolas Picard makes a boat called JetCycle in 2020. He uses the idea of a flying boat.
He changes it a little. He puts foil in the front and at the back. This makes the boat fly. The boat can move at 9 kilometers per hour.
One boat costs 12,000 euros. Picard wants to sell 100 boats in the next three years. Picard hopes that people will enjoy this new activity.
Difficult words: athlete (a person who plays a sport), pedal (to push your feet on a part of a bicycle to move it), foil (a piece of thin metal material), activity (something that people do).
You can watch the original video in the Level 3 section.
