Next generation Design of Experiment
Why use Sequential Learning?
Sequential Learning accelerates product development by reducing the number of experiments required to find new materials that meet performance specifications. This workflow is effective in projects with small, sparse data sets because it works through an iterative approach. It enables extrapolation to new, higher performance materials.
High-Dimensional Materials and Process Optimization Using Data-Driven Experimental Design with Well-Calibrated Uncertainty Estimates.
Julia Ling, Maxwell Hutchinson, Erin Antono, Sean Paradiso, Bryce Meredig. Integrating Materials and Manufacturing Innovation, 6(3), 207–21 (2017).
What is it?
Sequential Learning is an iterative data-driven method of exploring a parameter space.
- AI models are trained on existing materials data
- The models sift through the design space of possible candidate materials to surface new candidate materials for evaluation
- The product developer selects experiments to run from the suggested list, collects the data, and adds that data back in to the training set
- The model learns from the new data, gets smarter, and provides new experimental suggestions
How does it find new, higher performing materials?
Typical AI models are not effective at extrapolation. Our Sequential Learning workflow leverages state-of-the-art uncertainty estimates. These uncertainty estimates mean that our AI models can explore and extrapolate systematically. This approach means that our AI models can find new materials that outperform all the materials in the original data set.


Ditch Your Biological Clock—Science Says Older Moms Are Better Parents
Promising findings for women who had their kids at 35 and older.
Rido/ShutterstockAmerican women are waiting longer than ever to have kids, which is changing families, lives, and economies. Such a shift is largely driven by more women getting an education and entering the workforce, causing them to marry and start having kids later in life. Statistics from the U.S. Centers for Disease Control and Prevention show that, from 2000 to 2014, the amount of first births of women aged 30 to 34 increased 28 percent, and those over age 35 went up 23 percent.
Turns out the kids born to women 35 years and up are reaping the benefits, reports a new study, conducted at the School of Business and Social Sciences at Aarhus University in Denmark. The study authors determined that older mothers were light on physical and verbal discipline of their children when they were between seven and 11-years old. Meanwhile, children of these specific ages showed “fewer behavioral, social and emotional difficulties,” than others.
According to the researchers, it seems older mothers have more stable relationships, more education, and more material resources. But such factors aside, they believe older mothers’ maturity makes way for less stress during pregnancy, and more positivity in their attitude about parenthood and their kids in general.
“We know that people become more mentally flexible with age, are more tolerant of other people, and thrive better emotionally themselves. That’s why psychological maturity may explain why older mothers do not scold and physically discipline their children as much,” notes one of the researchers Professor Dion Sommer. “This style of parenting can thereby contribute to a positive psychosocial environment which affects the children’s upbringing.”
Weighing in on the study’s findings, Michael J. Breus, PhD, attributes older moms having greater socioeconomic stability and better education to the ability to aid their offspring in avoiding behavioral, social, and emotional struggles. The issues I would be concerned about would be the health aspects of older pregnancy for both the mother and child.”
Though getting pregnant and having children at 35 or older certainly comes with health risks, the study’s findings are good news for older moms nonetheless.


On May 8th the Ukrainian World Congress (UWC) joins the international community in solemn commemoration for the millions of victims and in eternal gratitude to the brave men and women who made the ultimate sacrifice for a free world.
World War II, which had begun in 1939 with the Nazi-Soviet invasion and dismemberment of Poland, became the most brutal war in human history. Its cost is beyond calculation: in Ukraine alone, over 8 million lives were lost, over 2 million people were forcibly deported. Today we pay tribute to millions of Ukrainian men and women who bravely fought in the World War II, among them over 250 000 Ukrainians who served in Polish, French, British, US and Canadian armed forces. We owe them an eternal debt that can never be repaid.
Caught between the totalitarian and murderous empires of Hitler and Stalin, Ukrainian people fought valiantly against both occupying regimes. The end of World War II did not bring peace or freedom to Ukraine. Instead, Stalin’s Soviet Union brought oppression and tyranny to Ukraine, as well as to many other captive nations of Eastern Europe. For over four decades, Ukraine was forced to continue its struggle against the Soviet regime that persecuted and denied the Ukrainian people the fundamental right to live freely.
Today, the people of Ukraine are once again forced to fight for their land and freedom as Russia seeks to subjugate Ukraine to its imperialistic rule. Russia, the modern-day aggressor state, seeks to utilize World War II symbols to justify and glorify its occupation of Crimea and invasion of Ukrainian Donbas
“As we commemorate the millions of World War II victims and pay tribute to those who fought for a free world, the UWC calls upon the international community to heed the lessons of history. The most recent escalation of Russian aggression once again showed us how vulnerable peace can be”– stated Paul Grod, UWC President. «We must not appease a modern-day tyrant who is attempting to rebuild the Russian empire and re-establish the Soviet prison of captive nations”.

Layers of the Heart Wall.Created by BYU-Idaho student Jared Cardinet Winter 2015
Within the thoracic cavity, the heart is contained or held in place by a fibrous "bag" called the pericardial sac. The sac completely surrounds the heart. It is comprised of two serous membranes, one called the parietal (sac side) and the other the visceral (heart side) pericardium. Between the two membranes is a fluid filled space filled with a slippery liquid called pericardial fluid. The fluid allows the two membranes to slide past each other, allowing the heart to move freely within the supportive sac. If injury or damage occurs to the pericardial sac, excessive fluid may enter this pericardial space. This fluid entry can be very dangerous as it may cause a buildup of pressure that compromises efficient pumping of the heart. This condition would be referred to as cardiac tamponade. The treatment is to insert a long needle through the chest and into the pericardial space to remove the excess fluid. This treatment is a Hollywood favorite, think of the doctor Christine Palmer who inserts the needle into the chest cavity of Stephen Strange to save his life in the Marvel movie Dr. Strange.
Another purpose of the pericardium is to provide resistance to prevent the distension of the heart from stretching beyond the available pericardial space. The pericardium not only protects the heart from friction and overdistension with each heartbeat, but this bag also anchors the heart into the correct position within the mediastinum, or central part of the thoracic cavity (or chest cavity).
The wall of the heart is comprised of the epicardium, myocardium, and endocardium. The epicardium is the outer layer of the heart and forms the visceral pericardium. The myocardium is the muscular layer of the heart. The endocardium is the squamous cells that line the inner surface of the heart and are similar to the cells that line the inner surface of blood vessels that the heart is continuous with. The structure of the inner surface of the heart chambers is quite rough in appearance creating folds called trabeculae.


Sweet potatoes (yes, the new spelling is one word) are grown in the tropics, making a long-trailing vine with yellow or lavender flowers that seldom go to seed.
They flourish in warm climes growing from late spring till frost. In cooler climes, they seldom flower, but can produce their tubers if planted in a warm sheltered spot.
They are the most drought hardy veggie out there; growing well even in the hot Florida summers. No wonder they are the potato of choice in the south.
In the Landscape
Do not confuse the ornamental purple and lime green leaved varieties of sweetpotato vine with the veggie varieties. The ornamental varieties do not produce tubers! Real sweetpotato plants make a great ground cover also in the ornamental garden. Even without flowers, the leaves are large and lush, looking attractive for most of their season.
There are a couple varieties that have a bushy growth for small beds or even containers.
In the Kitchen
Sweet potatoes are very popular now with more vitamins than white potatoes and are a better choice for diabetics or those watching their carb intake. Funny, although they are sweeter than white potatoes, they have lower carbs.
Use them baked, fried, pureed, grilled, roasted or mashed (although you may want to blend with white potatoes as the flavor of mashed sweets is quite potent and rich). Add 1 sweetpotato to soups and stews for rich flavor and color. In the south, they are the potato to use for a classic “steak and potato” dinner. Usually dressed up with butter, cinnamon and brown sugar, these potatoes are equally delicious spiced up with peppery seasonings.
Growing Organic Sweet Potatoes
Although the vines may be attacked by slugs and other pests making them unattractive, the tubers can develop in good shape with little marring.
Don’t leave them in the soil too long as then will become susceptible to soil parasites.

Relief as Oxford develops cheaper malaria vaccineFriday September 09 2022
The fight against malaria has received another breakthrough after scientists at the Oxford University developed a cheaper vaccine that can be manufactured at a greater scale.
The new vaccine can offer protection for two years and has been referred to as a 'game changer in the fight against the disease.'
Malaria remains one of the top 10 causes of death in Kenya and a leading killer of children under the age of five. The Lancet Infectious Disease journal has published trial results from 409 children in Nanoro, Burkina Faso showing the vaccine can give up to 80 percent protection.
"We think these data are the best data yet in the field with any malaria vaccine," said Prof Adrian Hill, director of the Jenner Institute at the university.
The Oxford team will start getting approvals for the vaccine, with the final decision pegged on the results of a larger trial sampling 4,800 children planned before the end of the year. The world's largest vaccine manufacturer - the Serum Institute of India - is already lined up to make more than 100 million doses a year.

Faster emergence and earlier tuber development
A new pre-sprouting technique – continued development of the method
Project manager: Jannie Hagman, Department of Crop Production Ecology, SLU
Organic potato production is very difficult, as evidenced by the fact that the area of organically grown potatoes in Sweden has decreased by 10% since 2004. The great problem for production is the risk of leaf blight attack. There are no properly effective control methods available and the existing control products can at best delay attack by a week or so. Pre-sprouting speeds up development of the potato plant and gives faster emergence, by up to 7 days compared with non-sprouted seed potatoes. Adventitious root formation on the tubers is important for emergence rate.
Pot and small-plot experiments carried out during the period 2005-2007 produced very good results. In pot experiments with a number of harvesting times, it was possible to demonstrate that tuber formation began earlier in plots where root development had been stimulated. In small-scale field experiments, the new method gave 6-21 %-units higher tuber yield in comparison with traditional pre-sprouting. Potato variety and pre-sprouting period influenced the results.
In this project, the method will be tested on a larger scale under more field-like conditions. The importance of:
- length of the pre-sprouting period and
- sensitivity to mechanical handling during planting will be investigated.


Gaining resilience by managing variability
Natural Capital represents the set of goods and natural resources on which society depends and impacts upon. Ecosystem functions, which can range from carbon sequestration to water regulation or biodiversity conservation, represent the production, regulation and cultural functions that ecosystems provide, as well as the possibility of co-creation of strategies between cooperating parties. Ecosystem services are the subset of those functions that have utility for human activities.
The most important habitats and ecosystems, either due to the presence of rare and threatened species, or to the existence of valuable biological resources, are not distributed homogeneously nor do they occur disconnected from the various occupations and uses given to the territory. The existence of high natural value (biodiversity with conservation value) or high ecological value (natural systems and wild resources with relevant socio-economic value) can be assessed and mapped to optimize their management and promote sustainable use.
Both in terms of agriculture and forestry or renewable energy production, the need to invest in decarbonization and to understand how ecological risk (e.g., loss of biodiversity, deregulation of ecological functions of crop protection) and climate risk (e.g., deregulation of the carbon sequestration cycle, change in seasonal patterns, forest fires, floods and droughts) work becomes essential to plan in the short, medium and long term the different phases of evolution and adaptation of the planning and management model.
Ecosystems, whether natural or managed by human activities, go far beyond 'landscape', they are sources of food, water, bioenergy production, among other goods and services, as well as the regulation of nutrient cycles, pollinator populations and natural enemies of crop pests, the risk of fires and natural disasters and are essential for carbon sequestration and related climate mitigation. In addition to all this, they also enrich us culturally, provide leisure and learning experiences and inspire us with their beauty and distinctive characteristics. We all recognize that many of these services cannot continue to be identified as zero-worth externalities to the economy.
The aim of this project is to carry out an exhaustive survey of biodiversity and ecosystem services to explore the possibility of integrating them into a local management system of the company's vineyards, with a view to using the natural-based economy in the sustainable operational planning and development of the company’s wine production, guided by the sustainable development goals of the United Nations.


Combine results from multiple subqueries using the UNION statement
What is a UNION statement?
The UNION statement is used to combine results of two or more subqueries. It can be used in combination with another SQL commands.
SELECT * FROM customers
SELECT * FROM employees
This code selects all results from the collection customers and concatenates it with all results from the collection employees. If some fields are not present in one of the collections, the are filled with NULLs.
Using UNION with WHERE
In the following example, we union two subqueries on the same collection with different WHERE condition.
SELECT id, price FROM products
WHERE NOT taxable
SELECT id, price * 1.15 AS price FROM products
UNION WHERE can be used to build complex logic into your reports, however, in the previous example, it would be more efficient to use simple IF function.
SELECT id, IF (taxable, price * 1.15, price) as price FROM products
You are now armed with useful knowledge of combining data with the UNION statement. Here are more articles to help you with your data analytics tasks with Jetspike.


Japan Kept The Train Station Running for Just One Passenger
Situated in Japan’s north island of Hokkaido, the Kami-Shirataki train station has only two trains that stop by every day on a special timetable.
It all started three years ago, when Japan Railways decided to shut down it’s services in the remote location, as ridership had dramatically fallen. That is until they noticed a young girl still using it to get to school.
When the company learned of their only passenger, they decided to keep the station running until she graduates. They even went the extra mile and re-scheduled the train’s timetable according to the girl’s schedule, according to CCTV News.Since then, the train stops once to pick up the girl and only a second time to drop her off after school. The station is set to close March. when the girl finally graduates.
When news broke of the Japanese government’s efforts for this young girl, people have been all praise. “
According to CITYLAB, Japan faces a number of crises, with record-low birthrates, aging population and the possibility of losing a third of its population by 2060, which have all been contributing factors that have hit the country’s railroad system. Kami-Shirataki station, which is in a rural part of Hokkaido, lost close to 20 rail lines in the past few decades, reported Fortune.


Coal-based power plants are a major source of air pollution in India. After notification of emission standards for coal plants in December 2015, it’s been six years of sluggish implementation of the same resulting in huge health and economic damage costs. The report “Health and Economic Impacts of Unabated Coal Power Generation in Delhi-NCR” attempts to answer the questions, “What is the impact of continued power plant operations on air quality, human health and economics without the adoption of emission control technologies as directed under the MoeF&CC, 2015 notification for coal-based power plants in Delhi NCR”.
The study highlights that pollution from these power plants travels hundreds of kilometres and impacts public health in states far from their vicinity and the Delhi-NCR region, i.e. Uttar Pradesh, Madhya Pradesh, Rajasthan, Gujarat, Maharashtra, etc.
The report found that the operation of power plants in Delhi-NCR with pollution controls in line with the emission standard notification would have negated 3000 lives lost, 3.2 million work absence days, > 4700 preterm births, > 7700 Asthma emergency room visits and ~3000 COPD cases in 2018. The report also highlights that operation of power plants according to the standards would have saved nearly ₹4800 Cr in 2018 by avoiding welfare losses and forgone labour costs caused by air pollution impacts.


It is incumbent on the researcher to clearly define the target population. Sometimes, the entire population is small enough to be included in the study. In other instances, the population is too large for the researcher to attempt to survey all of its members. Therefore, a small, but carefully chosen sample is used to represent the population. The sample is the actual group targeted either directly or indirectly and reflects the characteristics of the population from which it is drawn.
Using the South University Online Library or the Internet, research, analyze, and select at least two articles on sampling methodology used in public health research studies.
Note: The articles should not be more than two years old.
Based on the articles identified, create a 2- to 3-page Microsoft Word document that includes the following:

The refrigeration compressor is the core and heart of the refrigeration system. The capacity and characteristics of the compressor determine the capacity and characteristics of the refrigeration system. In a sense, the design and matching of the refrigeration system reflects the capabilities of the compressor. Therefore, the refrigeration industry of all countries in the world has invested a lot of energy in the research of refrigeration compressors, and new research directions and research results continue to appear.
The refrigeration compressor is the core energy-consuming component of the refrigeration system. The most direct and effective way to improve the efficiency of the refrigeration system is to increase the efficiency of the compressor, which will bring about a significant reduction in system energy consumption. At the same time, it can also avoid a large increase in material consumption caused by only taking measures on the system (such as blindly increasing the area of the heat exchanger, etc.). With the increasingly serious energy shortage situation in the world, countries are paying more and more attention to energy-saving work and putting forward higher and higher requirements for the efficiency of energy-consuming products.
Due to various losses such as friction, leakage, harmful heat transfer, motor loss, flow resistance, noise and vibration, the actual efficiency of the compressor is far lower than the theoretical efficiency. Therefore, in theory, any measure that can reduce any loss can improve the efficiency of the compressor. This objective fact has led to a wide range and broad direction of energy-saving research on compressors, and a variety of research topics and research results.
The international energy-saving research work on compressors mainly focuses on several aspects: research on lubrication characteristics, friction characteristics of compressor bearing parts to reduce frictional power consumption and improve compressor efficiency; reduce leakage loss to improve compressor efficiency; use frequency conversion Or variable capacity technology realizes energy saving through the best match between the output of the refrigeration system and the user’s load. The content of this aspect, especially the frequency conversion technology, has been relatively mature and widely known.
The research on air valves is an old subject but also an eternal subject. The research on improving the design of air valves to improve compressor efficiency is endless and rewarding. There are many researches in this area, covering everything from valve materials, motion rules, structural optimization to applicable theories and testing methods.


Long passwords are best practice: easily use and remember long, strong passwords
Password managers are the best tool you can use to solve this common problem of username-password pairings: weak, reused passwords.
Weak passwords are those passwords which can be guessed with the help of computers. The weakest passwords are shorter than 16 characters. Have a look at the chart below.
Reused passwords are passwords which are used in more than one credential.
For example, one day you create a password for your supermarket loyalty program signup. At some point later, you use the same password to sign up for a new video chat service. You have just reused a password. When the supermarket loyalty program gets breached, your password could be discovered, then used by thieves. They would try your discovered password, in tandem with your known email address, on other services, hoping that you have reused it, thus allowing them to unlock a more valuable login.
Always use unique passwords. Don't allow yourself to be victimized by credential stuffing.
Replace your existing system with a password manager
Longer passwords are better passwords, all else being equal. Length is important because modern computers are powerful enough to guess shorter passwords.
When relying on our memory to track passwords, we make a tradeoff between password length vs password complexity. The more complex (usually taken to mean variety of symbols, numbers, and letters used) a password is, the shorter the password must be for a human to reliably remember it. Use a password manager.
The maximum length of a password is set by the developers of whichever service you're creating credentials for. Modern services do not have a limit that most of us will come up against. Certain other services, in Canada they're often banks, used to have absurdly low maximum lengths. You should be concerned if you're still forced to use passwords less than 16 characters in length. Talk to your customer support and ask them to have their product team to fix the limitation.
Transitioning to a password manager
None of us are starting with a clean slate. We all have accounts already. How to transition without losing our minds?

Welcome to featured Wiki of the Day where we read the summary of the featured Wikipedia article every day.
The featured article for Thursday, 16 December 2021 is Jameson's mamba.
Jameson's mamba (Dendroaspis jamesoni) is a species of highly venomous snake native to equatorial Africa. A member of the mamba genus Dendroaspis, it is slender with dull green upperparts and cream underparts and generally ranges from 1.5 to 2.2 m (4 ft 11 in to 7 ft 3 in) in length. Described by Scottish naturalist Thomas Traill in 1843, it has two recognised subspecies; the nominate subspecies from central and west Sub-Saharan Africa and the eastern black-tailed subspecies from eastern Sub-Saharan Africa, mainly western Kenya.
Predominantly arboreal, Jameson's mamba preys mainly on birds and mammals. Its venom consists of both neurotoxins and cardiotoxins. Symptoms of envenomation in humans include pain and swelling of the bite site, followed by swelling, chills, sweating abdominal pain and vomiting, with subsequent slurred speech, difficulty breathing and paralysis. Fatalities have been recorded within three to four hours of being bitten. The venom of the eastern subspecies is around twice as potent as that of the nominate subspecies.
This recording reflects the Wikipedia text as of 00:11 UTC on Thursday, 16 December 2021.

Winning the right to vote
Voting rights of the 1960s
In 1957 and 1960, laws were passed by Congress to safeguard African American voters. Despite this, during the 1964 presidential elections, they still faced difficulties in registering to vote, encountering opposition and even brutal violence during voter registration drives. In March 1965, Martin Luther King Jr. organized a march from Selma to Montgomery, Alabama, to draw attention to the issue. Following this, President Lyndon B. Johnson sent a voting rights bill to Congress, which was passed and became the Voting Rights Act of 1965.
The Act empowered the U.S. attorney general to dispatch federal examiners to assist with African American voter registration and abolished literacy tests in certain states. It had an immediate effect, with around 250,000 new African American voters registered by the end of 1965. The Act was subsequently strengthened in 1970, 1975, and 1982, and was extended for 25 years in 2006 by President George W. Bush.
However, in 2013, the U.S. Supreme Court invalidated a crucial provision of the Act in the Shelby County v. Holder case. The Court determined that states with a history of voter bias no longer required federal pre-approval to amend their election laws, affecting mainly Southern states. Chief Justice John Roberts cited improvements in voting conditions in these states as the reason for the Court's decision. President Barack Obama criticized the ruling, calling for new legislation to safeguard equal access to the polls for all voters.

In 1995, Richard Levine and Marty Guitierrez traveled to the costal region of Rojas, in the southern part of Costa Rica to investigate the beached aberrant form. While Marty distracted the pilot, Levine borrowed Marty’s knife and was able to cut away a small two inch square slice of skin before the carcass was destroyed. Levine then sent the sample by DHL shipping service to Ian Malcolm at his office in Berkeley University.
To further protect the specimen, he enclosed it in a stainless steel specimen container, with refrigerant gas to preserve it. Ian Malcolm had the sample tested at the San Francisco Zoo Research Laboratory by Elizabeth Gelman, the head of research at the zoo.
The sample was greenish, with a pebbled texture. The state of the tissue was very decomposed, and the exact measurements were four centimeters by six centimeters. Attached to the tissue was a two centimeter square green plastic tag. The epidermal cells in the skin had an unusual density of chromatophores (pigment bearing cells). The chromatophores could open and close, meaning that the animal that the sample had belonged to could change color. Also, Elizabeth showed Malcolm the presence of a femoral sweat gland, indicating that the animal had been male.
The lab also found that the sample contained Nucleated red blood cells, characteristic of birds. There was also atypical hemoglobin, differing in the way its base pairs were structured from regular lizards. There was also an aberrant white cell structure, which showed that the animal had an unusual immune system. There were also foreign cells under the outer epidermal layer, indicative of a fight. There were signs of chronic and continuous stress in its arterial vessels, owing to the stressful environment of Isla Sorna.

Laboratory Manager : Dr.-Ing. Jens Neugebauer Cavitation Tunnel K23
Ideally, cavitation tunnel tests are the basis of an efficient ship design. The transmission of powers by the propeller is combined with an unwanted physical occurrence, so-called cavitation.
On both sides of the individual propeller wings the pressure can drop so much that it falls below the steam pressure of the water. The water begins to vaporise at room temperature and pressure and side cavitation occurs. Particularly, collapsing steam bubbles cause erosion to propeller and rudder which should be avoided by all means. By cavitation tunnel tests, the general danger of cavitation as well as the areas where it frequently occurs can be investigated.
The characteristic of the propeller in homogeneous currents, the so-called open-water propeller test, can also be determined in the cavitation tank. Thrust and torque are measured and the propeller efficiency is calculated. These data are collected in a typical open-water diagram.
Cavitation tank K23 - Kempf & Remmers (Year of manufacture: 1963)
|Measuring section:||1100 mm x 300 mm x 300 mm|
|Fluid velocity:||9m/s max.|
|Propeller diametre:||15 cm max.|
|0,1 - 2 bar|
The dynamometer reaches a maximum of 5000min-1 and can transmit and measure forces of up to 500N and torques of up to 10Nm. The measurements are carried out via strain gauges for forces, differential pressure sensors for current velocity and pulse counters for rotational frequency. The sensor technology has been thoroughly revised and renewed recently and the measuring signals are acquired and processed with a measuring amplifier. Additionally, local velocities as well as velocity fields can be recorded with a laser-doppler anemometer, by means of a 2D linear motion system (e.g. the propeller wake).

Lesson 3: Why do we do bad things?
We all have done bad things. We know they are wrong, but we do them anyway. It’s called “sin” when we do what God tells us not to do or when we do not do what God tells us to do.
We do those wrong things because Adam, who represented us all, disobeyed God way back in the Garden of Eden. God said that if Adam sinned all humans who descended from him would be born as sinners.
Romans 5:12, “Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned”
Romans 3:23, “for all have sinned and fall short of the glory of God,”
When we sin God is deeply offended. Our morally fallen hearts keep us from understanding what is true about God and what is true about us. The damage caused by our fall in Adam continues to make us unable to do good for the right reasons. In fact what we call “good” isn’t really good at all if it’s not done for God’s glory.
Romans 3:10-12, “As it is written: ‘There is none righteous, no, not one; There is none who understands; There is none who seeks after God. They have all turned aside; They have together become unprofitable; There is none who does good, no, not one.’ ”
Sin makes us selfish, greedy, and rude. Only God can change our sinful hearts. This is why Jesus came. He paid for the sins of the people he specially loved. Just as Adam represented us in Eden, Jesus represented his people when he lived here on earth, and died for them on the cross on Mount Calvary.
Index of our lessons on Bible Basics
(Bible verses are quoted from the New King James Version of the Bible)


On December 13, 2013, Fordham Law School’s Center on Law and Information Policy published a study (Study) that paints a sobering picture of how many public schools across the country handle student data, particularly with respect to data they store and services they (and students) use in the “cloud.” There is little doubt that many school districts are strapped for cash and, indeed, utilizing cloud services provides a new opportunity for significant cost savings. However, according to the Study, some basic, low-cost safeguards to protect the data of the children attending these public school are not in place.
For example, some of the Study’s key findings include:
- 95% of districts rely on cloud services for a diverse range of functions including data mining related to student performance, support for classroom activities, student guidance, data hosting, as well as special services such as cafeteria payments and transportation planning,
- only 25% of districts inform parents of their use of cloud services,
- 20% of districts fail to have policies governing the use of online services, and
- with respect to contracts negotiated by districts with cloud service providers
- they generally do not provide for data security and allow vendors to retain student information in perpetuity,
- fewer than 25% specify the purpose for disclosures of student information,
- fewer than 7% restrict the sale or marketing of student information, and
- many districts have significant gaps in their contract documentation.
A data breach can be significant for any organization, and school districts are not immune. Parents are also beginning to pressure districts for more action, particularly as children can be an attractive target for identity theft.
The Fordham Study provides a number of helpful recommendations for public school districts. Indeed, based on the Study and consistent with basic data privacy and security principles (not to mention FERPA and other laws concerning the safeguarding of student data), there seems to be quite a bit of low-hanging fruit school districts can use to address the risks identified. These include, for example, establishing basic, written privacy policies and procedures that apply to cloud and similar services, implementing more thorough vetting of vendors handling sensitive personal information, and adopting and implementing for consistent use a set of strong privacy and security contract clauses when negotiating with all vendors that will access personal and other confidential information.


Book Report Outline Book reports should be typed (double-spaced, 12 point). Correct spelling, grammar, punctuation, and use of paragraphs with topic sentences are an expectation. The entire report should be written in present tense. Cover Page Each report should have a separate cover page that contains the following information: A. Title of book B. Author C. Genre D. Publisher E. Copyright year F. Number of pages Part I: Book Summary Your first one to two paragraphs should be a brief summary of the plot. You should state the book’s title and author, and then you should describe the setting, main characters, and basic action of the book. Part II: Analysis Your next two to three paragraphs should be an analysis of the book. Consider answering some of these questions: A. What is the best or worst part of the book? Why? B. What did you learn from the book? (new words, facts, ideas, etc.) C. What is the author trying to teach? How did he/she teach this? D. Which character do you like the best or the least? Why? E. How does this book compare to other books about the same subject or by the same author? Remember, each paragraph should focus on only one idea. Part III: Your Recommendation In your closing paragraph, you should state whether or not you recommend this book to other students. Be sure to explain why you feel the way that you do. Additional Ideas You may begin your report with information about the author, such as his/her personal background, other books he/she has written, and any awards he/she has won. If you really enjoyed your book, you want to convince others to read it. One way to do this is to begin your report with good reviews that others have written about the book. For example, you may write “The New York Times calls this the year’s best book.” This shows that many other people enjoyed the book, too.


Both Funds flow and Cash-Flow statements are used in analysis of past transactions of a business firm. The differences between these two statements are given below:
Difference # Funds Flow Statement:
1. Funds flow statement is based on accrual accounting system.
2. Funds flow statement analyses the sources and application of funds of long-term nature and net increase or decrease in long-term funds will be reflected on the working capital of the firm.
3. Funds flow statement is more useful in long range planning.
4. Funds flow statement is a broader concept, it takes into account both long-term funds and short-term funds into account in analysis.
5. Funds flow statement tallies the funds generated from various sources with various uses to which they are put.
6. The changes in current items are adjusted in the statement of changes in working capital.
7. Funds flow statement shows the funds generated and applied as regards long-term assets long-term liabilities and capital.
8. Sound fund position does not necessarily mean sound cash position.
Difference # Cash-Flow Statement:
1. While preparation of this statement, all transactions effecting the cash and cash equivalents are taken into consideration.
2. Cash-flow statement considers only the increase or decrease in current assets and current liabilities in calculating the cash flow from operations.
3. Cash-flow statement is more useful for identifying and correcting the current liquidity problems of the firm.
4. Cash-flow statement only deals with one of the current assets on assets side of balance sheet.
5. Cash-flow statement starts with the opening balance of cash and reach to the closing balance of cash by proceeding through sources and uses.
6. In this statement cash from operations are calculated after adjusting the increase or decrease in current assets and current liabilities to operating profit before working capital changes.
7. Cash-flow statement shows the cashflow from operating, financing and investment activities.
8. Sound cash position is always followed by sound fund position.

A Greener Funeral
A Greener Funeral was launched on the 40th Anniversary of Earth Day, April 22, 2010, and is sponsored by Passages International, Inc. The goal of this organization and accompanying resources is to educate the general public about ways in which they can leave a lighter footprint on this earth by selecting a greener funeral. How green a family ultimately decides to be is entirely up to them.
According to National Geographic, “American funerals are responsible each year for the felling of 30 million boardfeet of casket wood (some of which comes from tropical hardwoods), 90,000 tons of steel, 1.6 million tons of concrete for burial vaults, and 800,000 gallons of embalming fluid.” This translates to nearly 1,000 tons of casket steel, 20,000 tons of concrete in burial vaults, and enough wood used in coffins to build more than three dozen homes within about ten acres of a typical cemetery.
Embalming is not known to have any environmental or health benefits and is only rarely required by law, such as in some instances of interstate transport of the remains or following death by infectious disease. Contrary to popular belief, an unembalmed body will not spread disease in the surrounding environment, according to the Center for Disease Control. Also, embalming fluids are generally formaldehyde-based. Formaldehyde is a chemical commonly used in many preservative materials and construction materials such as particleboard, and while it is a naturally occurring chemical, which readily biodegrades in the ground and in the air, it is also recognized as a carcinogen by the EPA, and is known to cause adverse health effects over long periods of exposure. This is especially relevant when considering funeral service employees who perform embalming procedures on a frequent basis.


Australian Colonial Silver
The Australian Colonial Silver Project began with the acquisition of the “University of Melbourne Wilson Hall Presentation Trowel Set” which had been specifically made for the purpose of laying the Foundation Stone at the University of Melbourne. The Vizard Foundation consulted with the University and agreed that it was critical that this important piece of colonial history should be retained in Australia. After acquisition the Foundation immediately placed it on permanent loan with the University of Melbourne art collection.
Subsequently, the Foundation acquired a number of other significant objects of colonial silver and in 2004 reached agreement with the Gold Treasury Museum Victoria (later the City Museum) to house the entire Collection on permanent display. In mid-2010 the City Museum closed down, and the Foundation decided that the collection was too small to justify a significant on-going exhibition at a major museum.
The bulk of the collection was sold in 2012, however 17 significant pieces remain, and these are on permanent loan to Werribee Mansion under the custodianship of Parks Victoria. The Mansion develops regular displays centred around various aspects of colonial life, and utilises these items on a rotating basis, together with other silver pieces and specially created didactics and audio-visual displays to illustrate the social, cultural and artistic heritage of the times.


There are four (4) elements of a basic contract:
- Acceptance: acceptance must be in identical terms to the offer, otherwise it will be a counter-offer, and acceptance must be given in a reasonable manner and in a reasonable time
- Consideration: consideration is the price of the two sides of the bargain i.e. what each person will receive in consideration for performing his part of the contract
- Intention: intention to create legal relationse. parties of a contract must intend legal consequences to attach to their agreement
In a contract for the sale of goods there are three (3) important points:
- Time or circumstances under which the ownership of the goods passes from the seller to the buyer
- when payment is due
- at what stage the risk of damage to or loss of the goods moves from seller to buyer
In international sales it is common for one party to make an offer on his own Standard Terms, and another party to accept that offer on his own Standard Terms. If seller’s and buyer’s terms are different, there will not, in strict legal theory, have been an acceptance in identical terms to the offer. This may well lead to the conclusion that there was no valid contract. Adoption of an internationally recognized set of standard terms (such as INCOTERMS) of governing International Sales prevents this by ensuring that both parties (buyers and sellers) are in agreement as to the terms contained in their contract, there is a valid contract and both parties are well aware of their rights and obligations. INCOTERMS form produced by the International Chamber of Commerce.
Under English law, a sale of goods is defined as ‘A contract to pass the property in goods for a money consideration, the price’. Hence, the ownership of the goods are transferred in exchange for a payment of money.

Low self-esteem is a common concern for many people, and it can impact several aspects of life. Although not a formal diagnosis, low self-esteem is an associated feature of anxiety and depression. Low self-esteem can impact school performance, work tasks, social relations, and make it difficult to pursue romantic relationships. Low self-esteem can lead to social isolation, lack of motivation, and receiving little joy out of activities.
As common as low self-esteem might be, many people don’t realize it when their self-esteem is unusually low. Low self-esteem can be sometimes described or experienced as lacking self-confidence. Many people with low self-esteem worry about what people will think about them, often worried that they won’t be liked. This can lead some people with low self-esteem to be passive in interactions with others and to have difficulty with assertiveness. People with low self-esteem often report having a lack of zeal for life or feeling “bummed out,” while others might worry that they won’t be able to do a job or task well enough at work
Many of the treatment approached used for depression and anxiety can help address low self-esteem. These included developing an understanding for the cause of the low self-esteem, validating those experiences, and working toward changing your perspective about yourself. Therapy can explore the messages that you have heard about yourself from others, as well as your own beliefs about yourself. Therapy can also help you develop techniques to affirm yourself and improve your thoughts about yourself.

Voting plays such a major role in the American government; the people are choosing who they trust to steer their nation in the right direction. However, it is not treated as seriously as the process actually is.
It is a big deal to elect someone into office since that means granting them power for years and trusting they will do the right thing. In 2016, only around 50% of the voting population actually exercised their right by voting in the election and with the primary elections this year, it is evident that voting is not a priority for most people making them not take their vote seriously.
Voting affects the entire country so it is important that each person knows who they are voting for.
Many candidates are judged based off of profiling rather than their political beliefs. For example, many people dismiss Bernie Sanders’ legitimacy because he is an older candidate, without even listening to what he has to say about what he would do as president.
In contrast, in 2016 when Hillary Clinton was running for president, while many people did relate to her ideals, it was clear that she did have at least some supporters who only voted for her because they wanted a woman president.
Of course, it is not wrong to relate to a candidate’s background, but when placing someone as the executive head of the nation, it is more necessary to expand upon that background to see what each candidate has to offer and what they stand for.
With such a competitive election in 2020, it will be even more important that people understand the name they are voting for, more than just a false smile or thirty second commercial with empty promises. A voter should always know the ideals or at least the general plan of the candidate they support before checking that box.

ROME (AP) -A trunk with its lid left open. A wooden dishware closet, its shelves caved in. Three-legged accent tables topped by decorative bowls. These latest discoveries by archaeologists are enriching knowledge about middle-class lives in Pompeii before Mount Vesuvius’ furious eruption buried the ancient Roman city in volcanic debris.
Pompeii’s archaeological park, one of Italy’s top tourist attractions, announced the recent finds on Saturday. Its director Gabriel Zuchtriegel said the excavation of rooms in a domus, or home, first unearthed in 2018 had revealed precious details about the domestic environment of ordinary citizens of the city, which was destroyed in 79 AD.
In past decades, excavation largely concentrated on sumptuous, elaborately frescoed villas of the Pompeii’s upper-class residents. But archaeology activity in the sprawling site has increasingly focussed on the lives of the middle class as well as of servants and others.
“In the Roman empire, there was an ample chunk of the population that struggled with their social status and for whom ‘daily bread’, was anything but a given,” Zuchtriegel said.
“A vulnerable class during political crises and food shortages, but also ambitious about climbing the social ladder.”
The finds unveiled include furnishings and household objects in the domus, which was dubbed the House of the Larario for an area of a home devoted to domestic spirits known as lares. The home unearthed in 2018 has one in the courtyard.
Zuchtriegel noted that while the courtyard also had an exceptionally well-adorned cistern, “evidently, the (financial) resources weren’t enough to decorate the five rooms of the home”. One room had unpainted walls and an earthen floor apparently used for storage.


Ear Nose | Otorhinolaryngology | Nasal Congestion (Symptom)
Nasal congestion or stuffy nose is a term that refers to the obstruction of airflow in and out of the nose. In contrast, the term nasal discharge means a discharge (fluid) from the nostrils.
Nasal congestion is most often the result of inflammation and swelling of the tissues lining the nasal passages and sinuses. Less commonly, anatomical obstructions (such as a deviated septum, foreign bodies) can lead to nasal congestion. Prolonged use of certain nasal decongestant sprays or drops can lead to a worsening of nasal congestion.
Rarely, tumours of the nasal passages or chronic medical conditions can cause congestion of nasal congestion. This refers to the presence of increased secretions and mucus in the nostrils, usually arises from a common cold, allergic reaction, inflammation or infection of the sinuses (sinusitis). Infections of the paranasal sinuses are infections caused by a pathogen (virus, bacteria or fungus) that grows in the sinus and causes blockage intermittent sinus ostium.


Herbs In Alternative Drugs Used For Self
Various medicine was as soon as an area regarded by many as pure quackery. Complementary and alternative remedies include natural substances like vitamins, nutritional dietary supplements, and herbs, in addition to therapies like homeopathy, acupuncture, and hypnosis. People usually use complementary practices along with care from their medical physician to take care of continual well being problems, deal with signs, or stay wholesome.
Individuals who have been white, female and youthful had been more doubtless than different cancer patients to use complementary therapies, the research letter says. Mind and body practices concentrate on the interactions among the brain, body and behavior, to affect physical functioning and promote health.
And we also provde the meanings of frequent and complicated phrases in health and drugs and a information to various drugs and holistic healing. You could find herbs and different medicine treatments in pill, capsule, ointment, and cream kind at well being meals shops, pharmacies, and even some supermarkets.
It included some natural drugs to permit her to get through the complete course of conventional remedy. Rigorous, effectively-designed medical trials for a lot of complementary and alternative medication practices are sometimes lacking. Scientifically unsupported well being practices can lead people to forgo efficient treatments and this may be referred to as alternative value".
Similar Hormones For You? Various Drugs And Conventional Medication
Usually, alternative drugs differs from traditional medication in that various medication is older and what we would name unconventional or non-Western medicine. If they failed to offerÂ pure" therapies, some hospital executives concern they’d lose a chance to draw patientsÂ who want more profitable care, resembling orthopedic surgeries or most cancers therapies. This is when some people will try different medicine.
Improved communication between patients and caregivers and higher scrutiny of the usage of AM for the preliminary therapy of most cancers is required. For minor health issues, alternative medicine is usually not dangerous. This can be a troubling and harmful development, especially within the case of herbal dietary supplements – the most common CAM.
The National Middle for Complementary and Various Medication (NCCAM) is the Federal Authorities’s lead company for scientific analysis on complementary and various medication (CAM). Most are considered to be outside the realm of conventional medication, although others, together with vitamin D , train , acupuncture and cooling methods , for example, are establishing their position in comprehensive care by scientific study and medical trials.


Or is Microsoft greener than Google? Hard to say, as both companies have significant ranges of green activities going on in Seattle and Silicon Valley. CNet compares the two, and they both look pretty good:
Being portals and search engines, the companies are likely among the worst energy users because of the cooling and energy their data centers need to operate. When asked, company representatives did not say what, if anything, the data centers are doing to improve efficiency and reduce energy.
No doubt, Google and Microsoft, two of the top Internet sites in the world, use massive amounts of electricity to power and cool their data centers. But outside of the electricity that makes the businesses run, they are among the leading adopters of so-called green policies in corporate America.
Subsidies for buying Priuses? Check. Solar panels? Check. Hormone-free chicken in the corporate cafeteria? Check. Between them, they’re doing a variety of things to try to make the Sierra Club, organic farmers and Al Gore proud.
“Any organization that looks at a way to become more efficient and reduce its energy consumption and emissions and makes facilities more human friendly and less toxic and more resource-conscious from the standpoint of sustainability is taking positive steps toward living in the environment in a more compatible way,” said Stan Van Velsor, global warming program coordinator for environmental group Sierra Club‘s Loma Prieta Chapter office in Palo Alto, Calif.
What impresses me in both cases is the variety of green practices: green building, renewable energy use, organic and local foods, composting and recycling… Each seems to recognize that “green” doesn’t just mean putting a recycling bin in the break room, but involves looking at the whole environment, and how that environment affects the people working in it. No doubt these companies are using lots of electricity, but if more American companies followed the lead of these two technological giants, we’d be considerably better off environmentally… and all of those companies would likely have much happier employees. Sounds like goals worth investing in, don’t you think?

Acupuncture is the practice of treating people using needles and the Chinese system of medicine that governs which points are used.
People have been treated for thousands of years using acupuncture. Ancient texts describe a complex but fascinating insight into how the human body works. Acupuncturists use this tried and tested theory and apply it to modern complaints.
A traditional acupuncturist views the body as a reflection of the greater world. As such, the body is in constant, dynamic interaction with the environment. Health in this system is not static, but rather the ability to adapt gracefully to all the changes and challenges that life sends ones way. Anything from environmental conditions (for example living in a damp house) to dietary choices and the emotional stresses that work/life throws up can upset this delicate balance and create illness. A healthy person can manage these changes while maintaining their health.
Acupuncture treatment in Cardiff at The Llandaff Clinic is aimed at reducing pain and restoring normal function of the muscles. This approach helps with resolving your problem and enhancing your feeling of wellbeing. You may notice other niggling problems resolve as your main health complaint improves.
Acupuncture originated in China and other far eastern cultures where it still features in mainstream healthcare, both as a stand-alone therapy and in combination with conventional western medicine. Acupuncture is now widely used and accepted worldwide. In the UK an ever increasing number of people are discovering what acupuncture can do for them.


find is the basic Unix command used to search files recursively under a directory tree. It is default available in all the Linux operating systems.
All the Linux command line users must be aware about uses of Linux find command. It The find command traverse under a directory tree and capable to search files or directory based on defined search pattern. It also provides option to search files with names in uppercase or lowercase or mixed case.
In this tutorial you will learn about how to search files with case insensitive names.
Find files with Case Insensitive Names
Use -name command line option followed by the file name under a directory tree. The below command will search all files with name backup.zip under the current directory and sub directories.
find . –name backup.zip
The above command searches files in case sensitive names.
-iname option to search file names in any case. Here iname means insensitive names. The following command will match all patter like Backup.zip, BACKUP.ZIP, backup.Zip or BackUp.Zip etc.

Early black bear hunting season is upon us in New York State. The season runs from September 10th through the 25th in specific wildlife areas throughout Southeastern region of the state, and from September 17th to October 14th in the Northern areas.
In some parts of the state, bear hunting continues through the end of the year. The season for Westchester County begins later in autumn and can run throughout December, depending on hunting methods and exact location.
Early season hunters have the option of using a bow (if eligible), a crossbow, a handgun, a shotgun, or rifle (where allowed).
Hunting is not only popular in many circles (more than 38 million Americans hunt and fish), but it can also be an important part of population control. During this time of year, black bears are feeding heavily and can potentially pose a threat when they forage in fields for food. Bear hunting plays a valuable role in keeping the populations of deer and elk at their proper levels; because bears prey on these animals, having too large of a bear population can threaten other animal populations.
If not kept in check, bears can raom beyond forest borders and can come in contact with pets and humans. Recent bear attacks in Pennsylvania were responsible for the death of two goats within a short period. In one attack, the bear in question jumped right over a dog house to get into the goat’s pen.
Authorities say to be careful with food items and trash, and to keep close watch over children and pets when they’re outdoors.

Can wind turbine blades be recycled?
Yes! Respecting the environment doesn't stop with delivering clean, renewable energy to our customers. It also means doing everything we can to recycle and repurpose any and all of our equipment, including turbine blades.
When wind turbine blades become worn or outdated, we replace them with new, larger blades that can generate even more electricity. But, those old blades can still be used in other ways. Nearly all of the components that make up a turbine blade can be recycled or salvaged, and the rest can be repurposed. Find out how it's done!
So, how are turbine blades recycled?
Turbine blades are mainly composed of metal, balsa wood and fiberglass. Metal components such as iron, steel or copper are valuable scrap materials. Balsa wood in a turbine blade is burned to generate heat needed for processes like pyrolysis – the extraction of glass fiber from the rest of the shredded blade remnants. Fiberglass, once extracted and processed, has a number of uses. The following steps help us get what we need to re-purpose the recycled pieces.
Cut it fine
When a blade is removed for recycling, it needs to be cut down into sections for easier transportation. Our crews and contractors use wet-cutting tools and containment equipment to minimize fiberglass dust in the air and being left behind on the ground.
Strip it down
Once the blade’s been cut for transport and arrived at a sorting facility, each section is dismantled to separate the different materials and prepare them for their next destination. The smaller, nonmetallic sections are shredded to reduce in size further. Depending on what the shredded materials will be used for, the final result could be as fine as a powder!
Once the blade contents are processed accordingly, the recovered materials are provided to manufacturers for use as raw material or to be upcycled for a variety of second-generation products.
Recycle and Re-Use
Our recycling partners work with manufacturers that use recycled fiberglass for items such as:
- 3D printer filament
- automotive parts
- sports equipment
- cement kiln fuel additives
- binding agents for concrete mixes


For many of us, “coronavirus” was an unfamiliar word before the COVID-19 pandemic, but doctors have been dealing with coronaviruses for decades. Coronaviruses were the cause of SARS and MERS infections in humans and veterinarians regularly treat cats, dogs, pigs, and cattle for diseases caused by various strains of the virus.
There are currently no approved treatments for coronaviruses in animals.
After years of study, veterinarians know that, in animals, the majority of coronaviruses reproduce in the gastrointestinal tract and usually cause only mild intestinal issues that resolve without medical intervention.
However, one disease, feline infectious peritonitis (FIP), is often fatal. FIP occurs when an intestinal coronavirus mutates and infects white blood cells. When this happens, the virus (FIPV) leaves the intestine and travels throughout the body. In many cases, a strong immune system response eliminates FIPV before an infected cat experiences any symptoms. But, sadly, if clinical signs of FIP appear, there’s nothing vets can do. The disease progresses rapidly and is nearly 100% fatal. FIP is the leading cause of death in kittens and young cats.


Increase auditory processing
and social engagement
Developed by Dr. Stephen Porges, the Safe and Sound Protocol (SSP) is a fifteen-hour auditory intervention designed to reduce stress and auditory sensitivity while enhancing social engagement and resilience. Based on Dr. Porges’ Polyvagal Theory, by calming the physiological and emotional state, the door is opened for improved communication and more successful follow-up therapy.
The SSP is a research-based therapy showing significant results in just fifteen sessions in the following areas:
- Social and emotional difficulties
- Auditory sensitivities
- Anxiety and trauma related challenges
- Stressors that impact social engagement
Emotional and physiological state are critical to how we approach the task at hand. So when a client has better state control, not only can they be more socially engaged, they are more open to therapy. Better state regulation improves therapeutic outcomes.
This non-invasive intervention involves listening to music that has been processed specifically to retune the nervous system (regulating state) to introduce a sense of safety and the ability to socially engage. This allows the client to better interpret not only human speech, but, importantly, the emotional meaning of language. Once interpersonal interactions improve, spontaneous social behaviors and an enhanced ability to learn, self-regulate and engage are often seen.

The Vitality of the American Sovereign
19 Pages Posted: 1 Sep 2009
Date Written: August 30, 2009
In his book American Sovereigns: The People and America’s Constitutional Tradition Before the Civil War, Professor Christian Fritz argues that two very different conceptions of the American people’s sovereignty - one broad and one narrow - battled for the nation’s allegiance in the eighteenth and nineteenth centuries. Under the broad conception, ordinary citizens could take control of the nation’s day-to-day governmental affairs whenever they were unhappy with their elected leaders’ performance, and could alter their constitutional arrangements by any means they deemed appropriate. Under the narrow conception, citizens could influence day-to-day governmental affairs only through elections and other government-approved mechanisms, and could alter their constitutional arrangements only by those methods that were authorized by the ratified constitutional texts themselves. In Professor Fritz’s view, the broad conception faded from view in the years after the Civil War and the narrow conception now firmly prevails.
This review disputes Professor Fritz’s claim that the broad conception of the people’s sovereignty no longer plays a viable role in American politics. Citizens do still sometimes intervene directly in the nation’s day-to-day governmental affairs in ways that the people’s elected leaders have not approved, and they do alter their constitutional landscape by means other than those that the nation’s ratified constitutional texts explicitly authorize. More fundamentally, the American people have learned that they can transcend the more extreme elements of the broad and narrow conceptions of the people’s sovereignty. By engaging with their elected leaders in what can be called the “sovereignty dance,” the sovereign people have learned that they can retain ultimate control over their government while still permitting government leaders to retain the credibility and power they need in order to do the people’s work.

There are many ways parents can help children get the most out of speech-language or feeding therapy. Being involved and present during sessions can greatly improve your relationship with your therapist and child. This gives you the opportunity to ask questions, inform the therapist on your concerns/thoughts, and have open discussions about what is working and not working so that the therapist can provide your child the best care possible. Sometimes being present is not
always possible with families schedules; communication via phone/email is a fast and efficient way of keeping an open conversation with your therapist, and keeping you updated on ways to help your child progress in therapy. Ask your child’s therapist how you can practice the skills learned in therapy within your everyday routines. This is the best way for your child to make fast progress!
While communication with your therapist is very important, It is also important to follow through with the recommendations of the therapist after the session. After all, the child spends most of their time with the parents, not the therapist. Although skills are taught in the therapy room, practice and progress occurs outside the therapy room within the child’s everyday routines! If you feel the recommendations to practice at home are not manageable/realistic, ask your therapist for other recommendations that are more feasible for your family! Your therapist will always be able to find ways to help your child within your schedule, and having a good relationship and foundation with your therapist will make that possible! This article shows other ways you can make the most of your child’s speech therapy. https://www.friendshipcircle.org/blog/2013/07/23/6-ways-to-get-the-most-out-of-your-childs-speech-therapy/


Making Every Science Lesson Count: Six principles to support great science teaching£11.68
- Offers 6 pedagogical concepts to support science teaching.
- Supports a whole-school strategy for learning that could be adopted by all.
- Practical ideas and theories that can be used across all science subjects.
I love science. It’s just fascinating but allows for practical exploration, demands our attention, and challenges how we experience the world. For teaching though, getting the message across to our students can be challenging, as articulating theories and ideas that science offers is no easy task. This is relevant to science subject specialists in secondary schools. How can we articulate the passion and interest that science offers in a way our students understand, can access, and help develop their naturally curious minds?
In his new book, “Making Every Science Lesson Count: Six principles to support great science teaching” Shaun Allison, explores his 6 pedagogical principles that can support secondary students (ages 11-16 years) in grasping often complex theories in the three main science subjects, leading up to GCSEs. The six principles – challenge, explanation, modelling, practice, feedback and questioning – can inspire an ethos of excellence and growth across a whole school.
Throughout the book, Shaun explores the six principles with a thorough commentary, adding substance to his ideas, offering practical advice, ideas and strategies that can help develop deep learning for students in science lessons. Crucially, the ‘modelling’ principle is very well considered, with Shaun offering nine strategies (such as live modelling and scaffolding), which can really bring the relevant learning to life for pupils who may be struggling with a particular concept.
This book is ideal for all secondary school science teachers, or for those teachers who may end up covering science lessons. The six principles offered form a critical base to support pupils learning and to develop their scientific thinking in theories that can be conceptually challenging, and are relevant to the three main subjects areas covered within the science curriculum.

At The Clinic
Applied Behavior Analysis (ABA)
Our ABA intervention services hit the core of helping children with autism by following one simple rule: every child is unique, and we have to help them to best reflect those social needs. Through our Preschool ABA program, children learn by playing with their peers and with small group activities. Some learn to communicate by exchanging pictures or using an iPad. Others expand their verbal skills. We plan activities that encourage the children to interact – making dirt pudding, erupting baking soda volcanoes, playing water balloon T-Ball. At the elementary school level, actives offer the chance to practice how to attend an participate with age-appropriate lessons and learn from others through board games, dramatic play and conversations volleys.
Social Skills Groups
“My child just doesn’t seem to get what people mean sometimes.”
We hear this from parents often, and help them understand children with autism need help learning how to socialize, much as their peers learn academics. Our small groups meet weekly, where children practice life skills – maintaining a conversation, respecting personal space, coping with bullying.
Screening and Diagnostics
“I’m concerned my child might have ASD.”
Our clinic understands the fear and uncertainty that comes with the early suspicions about autism. We’re here to guide you through the process with years of clinical expertise using gold standard assessment tools, and the right questions are asked and answered:
- What signs should I be looking for?
- How early can a child be diagnosed with ASD?
- How do I help my child down this unknown path?


Diabetes affects your whole body and oral health, especially your teeth and gums. People with diabetes have a higher chance of getting gum disease and Periodontitis. Periodontal disease can lead to chronic bad breath, difficulty eating, pain and even tooth loss. Diabetes can also slow down healing, so it can interfere with treatment of periodontal disease. The effect is even greater when your blood sugar is not well controlled, making it harder to fight bacterial infections.
If your high blood sugar is not well controlled, you may have an excessive buildup of plaque bacteria. which can lead to serious oral health problems. Plaque is a clear, sticky layer of bacteria that forms on your teeth. If plaque remains on your teeth for a long time, it can lead to tooth decay and infections, such as the gum disease gingivitis.
Gingivitis is an early stage of gum disease. It is caused by a buildup of plaque and tartar on the teeth and along the gumline. If you have diabetes, it is harder for your body to control plaque bacteria. That is why people with diabetes are 3 to 4 times more likely to get gum disease.
Diabetes and Periodontal Disease
If gingivitis is left untreated, it can progress into periodontitis. This is a more serious form of gum disease. Periodontitis damages the soft tissue and can destroy the bone the jaw bone if left untreated. It can cause your gums to pull away from your teeth and lead to tooth loss.
Poor oral health can affect diabetes, too. If you have an infection like gingivitis or periodontitis, it can affect your blood sugar. That’s why it’s vital to practice good oral care habits such as using a toothpaste and mouthwash designed to fight plaque. Maintaining your health and care can help protect your oral health, as well as manage your diabetes.
If you have diabetes, consult your dentist if you experience any of the following:
- Swollen or sensitive gums
- Redness of the gums
- Bleeding gums

Is there a more environmentally acceptable alternative to using single-use surface disinfection wipes that contain plastic? Esther Jansen believes there is a better solution that could help hospitals reduce their impact on the environment.
Surfaces, especially those that are frequently touched, are a major source of crosscontamination and infection. This is why we frequently treat surfaces with cleaners and disinfectants, now more than ever before. Not only are we cleaning and disinfecting our surfaces more often, but we are also paying attention to more surfaces, such as door handles, elevator buttons, staircase rails, and touchscreens.
The appropriate cleaning and disinfecting of surfaces is an essential task. It contributes to creating a safe environment both in and outside the hospital for patients, staff, and the public. The consequence of our avid wiping, however, is that we have been clogging up our environment with singleuse, pre-wetted plastic surface wipes. So, is there a better alternative?
Plastic, and especially single-use plastic, is more than just a nuisance. The waste it creates is a critical issue for future generations. Plastic certainly has its uses and when made and used in a sustainable manner, for example by using recycled and reusable plastic, its impact on the environment can be minimised.

Lesson 7 Build Multiplication Fluency
Let’s multiply multi-digit whole numbers using the standard algorithm.
Warm-up Notice and Wonder: Same Solution
What do you notice? What do you wonder?
Activity 1 Greatest Product
Partner A chooses a number card and writes the number in one of the blanks for Round 1.
Partner B does the same.
Repeat until each partner has a two-digit by three-digit multiplication problem.
Find the product.
The partner with the greater product wins a point.
The partner with the most points after 5 rounds wins the game.
Activity 2 Desperately Seeking 9 New Units
Tyler notices that when he uses the standard algorithm and composes a new unit, sometimes there is 1 new unit, sometimes 2, all the way up to 8. He has not seen an example with 9 of the new unit.
For each of these products, how many of each new unit do you compose?
Do you think it is possible to compose 9 of a new unit with the standard multiplication algorithm?
Andre is playing Greatest Product. He says the greatest product it’s possible to make in the game is


|Display size||12 digits|
|Connection||IEC C14 inlet|
The Casio 122-F was an early financial calculator produced by Casio.
Special features[edit | edit source]
Through the use of the P key and multi position switch, additional advanced functionally such as square roots, inversion, and remainders can be accessed. This greatly expands the feature set of the calculator, while taking up minimal button space.
Internal design[edit | edit source]
The calculator uses three different boards internally, one for the power supply, one for the logic and display, and finally one for the keypad. The power supply section of the unit contains a multi tap transformer and a rotary switch for selecting the operating voltage, with options for 100V, 117V, 220V, 230V and 240V. A power switch is provided on the right side of the calculator to turn it on and off.
All of the computation is done on the logic and display board in the lower part of the front of the calculator. The main processor is a NEC D573C, a common chip used in Casio calculators of the era. The vacuum fluorescent display is housed in a long glass tube, a NEC LD8121. The display consists of twelve digits and thirteenth character for displaying symbols such as a negative sign.


The U.N. environment agency said Monday that leaded gasoline had finally reached its end after the last country to stop selling the highly toxic fuel.
The U.N. demanded that Algeria stop providing leaded gasoline last month. The Environment Agency declared the “official end to” leaded gas use in cars last month. This was a controversial decision that has been linked to a variety of health issues.
Inger Andersen (UNEP executive director), stated that “the successful enforcement of the ban sur leaded petrol was a significant milestone for global health, and our environment.”
Petroleum containing Tetraethyllead (a form of lead) was first sold nearly 100 years ago in order to improve engine performance. It was used extensively for decades before researchers realized that it could cause strokes, heart disease, and brain damage.
UNEP stated that studies had shown that leaded gas causes intellectual impairment in children, and can lead to millions of premature deaths.
Andersen stated that “the cost of environmental degradation” is real, citing a “very, very large number” of $2.45 Trillion in economic damage prevented by the ban.
Janet McCabe was the deputy administrator at the U.S. Environmental Protection Agency. She stated that blood lead levels had “plummeted”, literally and literally, after the fuel was banned in the United States.
In the 1970s and 1980s most rich countries began to phase out the fuel, but it was still used extensively in low- and mid-income countries up until 2002 when the U.N. launched an international campaign to ban it.
McCabe stated that leaded gas remains in small-plane aviation fuel. The EPA is working with the Federal Aviation Administration on this issue.
Antonio Guterres, U.N. Secretary General, stated that the success of the abolitions of leaded gas and the ban on ozone depleting chemicals showed the potential impact international treaties can have in addressing environmental problems.
He said, “We must now make the same commitment to end the triple crises climate disruption, biodiversity loss, and pollution.”
