Urban Teen Driving Study
Motor vehicle crashes account for 40% of all teen fatalities. Graduated driver licensing (GDL) is showing promise as a potential solution by extending the learning phase. There are also several different technologies that can support parental management of teen driving past the supervised learning phase and into the most dangerous time for newly licensed teens—the first 6 months of independent driving. The implementation of such devices may help to reduce the number and type of risky driving behaviors and to increase safe behaviors like seat belt use. This study addresses the potential for an event-triggered video system to reduce the number of safety-relevant driving errors made by newly licensed teen drivers. The system provides both immediate feedback and a 20-second video clip, giving the teen driver and their parent the opportunity to review and learn from mistakes as well as good responses. The event-triggered video system was placed in the vehicles of 18 newly licensed sixteen year old drivers for 52 weeks. The first six weeks established a within-subject baseline; no parental or system feedback was given during this time. During the next 40 weeks, feedback was provided to the teen driver in the form of a blinking LED on the camera and a weekly report card mailed to the parents. The report showed the driver’s weekly and cumulative performance regarding unsafe behaviors and seatbelt use relative to the other participants. The last six weeks was a second baseline period. Results showed that the intervention was successful in reducing the number of safety-relevant events by 61%, and by 75% among those teens who triggered the system most frequently during the initial baseline period. More importantly, the effect remained even after the intervention ended. In addition, seatbelt use increased to an average of 98% across all participants. Although there are limitations associated with such a naturalistic study, the results suggest that an intervention of this type can reduce the number of risky behaviors novice teen drivers engage in.

High School > Home Economics > Housekeeping Videos
If there’s one thing that parents really love to hate, it’s messy rooms. Surely, many parents have told off their kids for having rooms that look like a tornado went through them. The kids, meanwhile, just shrug it off and bring along this messiness into their adult lives.
True enough, many young adults who live by themselves have this tendency to leave their places untidy. Sure, they are indeed busy. They work hard. But that should not be an excuse to not clean up once in a while.
For that reason, home economics class should include topics on basic housekeeping. There are a few aspects of the home that always need to be regularly maintained: floor, carpet, sheets, pillows, couches, and more. Keeping them at least tidy, if not spotless, should be an essential life skill that every student has before approaching adulthood.
Good housekeeping skills are great assets for many people. It is another important aspect of getting their lives in order. Having good careers as well as well-kept homes makes a person both successful and respectable. It would also be easier to invite people over if the place is always tidy. There would be no shame having anyone over, even those occasional surprise visits by friends.
Knowing how to keep one’s home squeaky clean is also a great money-saving tactic. Instead of hiring someone to clean the place every now and then, people can just do it themselves. It may not seem like a lot of savings in the short run, but when compounded, the money adds up. In the long run, it’s surprising how much people stand to save in terms of cleaning expenses.
Also, the phenomenon of “I can’t find my things” can be avoided. When people have a habit of regularly tidying up their spaces, they would always know where their things are. They would always know where to keep the things that are out of place. There would be much fewer episodes of being late for work because it took too long to find an important document.

As details on the latest COVID vaccine contenders flood the news cycle on a daily basis, reports of concerns regarding the safety and efficacy of the vaccine are widespread among many demographics, even including the professional medical community.
As vaccine hesitancy grows agencies, including the World Health Organization (WHO), are stepping up efforts to build vaccine confidence through public relations and communications campaigns.
Surveys reveal vaccine hesitancy
Researchers from the University of California Los Angeles’ Karin Fielding School of Public Health surveyed healthcare personnel working in the Los Angeles metropolitan area. As the Washington Post reported, they found that two thirds (66.5%) of healthcare workers “intend to delay vaccination,” meaning they do not intend to get the COVID vaccine when it becomes available. They plan instead on reviewing the data once it’s widely administered and proven safe.
Seventy-six percent of the vaccine-hesitant healthcare workers cited the “fast-tracked vaccine development” as a primary reason for their concerns. Typically, vaccines take between eight to 10 years to develop, Dr. Emily Erbelding, an infectious disease expert at National Institute of Allergy and Infectious Diseases, told CNN in an article titled, “The timetable for a coronavirus vaccine is 18 months. Experts say that’s risky.”
The coronavirus vaccine frontrunners — Pfizer, Moderna and AstraZeneca — are expected to make their debut in January. The pharmaceutical giants have exponentially accelerated the average safety and review timeline for vaccine development and production, to get the vaccines to market in under a year. Erbelding admitted that the accelerated pace will involve “not looking at all the data.”
Susan Bailey, president of the American Medical Association, said in a video that the number of physicians expressing hesitancy was “unprecedented” and “posed a real risk” to public confidence in vaccines.
A recent Gallup poll showed that only 58% of Americans plan on getting the COVID vaccine when it’s available. An October poll conducted by Zogby found that nearly 50% of Americans have concerns about the safety of the coming COVID vaccines.

Heatwave warning for Caribbean
Posted in: Regional News by volderine | 16 July 2019 | 1264
(Barbados Today) While Europe is experiencing heatwaves, North America, Central America and the Caribbean are also at risk. The situation could worsen between July and August, with adverse impact on human health.
In view of the current heatwaves in Europe and predictions that this phenomenon will hit various parts of the Americas, the Pan American Health Organisation/ World Health Organisation (PAHO/WHO) is urging countries in the region to be prepared, due to the impact that this could have on people’s health, including the risk of death.
During the southern hemisphere’s summer of 2018-2019, seven countries in the Americas (Argentina, Brazil, Chile, Mexico, Paraguay, Peru and Uruguay) were affected by heatwaves, a phenomenon never seen before in the region. Two of the heatwaves that have had the greatest impact since 2000 include the one in Brazil in 2010 which caused the death of 737 people, and the one in Argentina in the summer of 2013-2014 which caused 1,877 deaths and left 800,000 people with no power, which increased heat stress in that population. According to health authorities in the United States, heatwaves are the natural phenomenon that causes the highest number of deaths in that country.
Weather forecasts for North America, Central America and the Caribbean predict heatwaves during the summer of 2019. This could increase drought-induced stress, lead to forest fires, and have harmful effects on human health.

South Garo Hills is an administrative district in Meghalaya, India. The South Garo Hills district is one of the newest districts in the state since the founding of Meghalaya. The creation of this district was declared on June 1, 1992 by branching from the former West Gallo Hills district. The early inhabitants of the district were the Garo. In the end, the area was placed under the control of British rulers by the authority of Emperor Mugar. In 1979, the Gallo Hills district was divided into two separate districts.
Famous for ?
The area is known for its many historical and tourist attractions, including the hills of "Dilsa Abri" in Bagmala, which is rich in rare "pitcher flowers". The famous Shiju Cave is also here.

An controversial American businessman, Russ George, has reportedlyÂ carried out a rogue geoengineering experiment in the Pacific Ocean off Canada’s west coast. The ocean fertilization experiment apparently dumped about 100 tonnes of iron sulphate into the ocean in July, later causing a massive algal bloom. The geoengineering action is being called out by as a blatant violation of two international resolutions by lawyers and environmentalists.
Satellite images appear to have confirmed the rouge experiment took place. The NASA satellite image above shows yellow and brown colors where relatively high concentrations of chlorophyll were in August 2012, after the iron sulphate was dumped into the Pacific Ocean. The experiment created an artificial bloom as large as 10,000 square kilometers.
The aim of the ocean fertilization experiment was for the algae to absorb large quantities of carbon dioxide as it sank to the ocean floor, locking the carbon dioxide away. However, scientists have been debating whether or not ocean fertilization using iron filings can indeed lock carbon deep in the ocean over the long term, and what other serious environmental impacts it might have down the line.
Concerns have been raised that such experiments could in the process damage ecosystems, cause toxic tides, cause ocean dead zones, and even worsen ocean acidification.Â The effects are being monitored to see what the impacts will be of what is the world’s largest geoengineering experiment to date.

Displaced by Violence in Ethiopia: A 9-Year-Old's Story
For 9-year-old Gabezech, home for now is a blue tent among many arranged high on a hillside in southwestern Ethiopia.
The camp where she now lives is one of six set up for IDPs — short for internally displaced persons — in Ethiopia's Konso Zone in the Southern Nations, Nationalities and People region. The camps, supported by UNICEF, were set up to house the roughly 84,000 people who were forced out of their homes over land disputes in late 2020. Tens of thousands of children have been uprooted, many separated from their families, leaving them at greater risk of disease, struggling to find shelter and more vulnerable to violence.
In the village of Kusume, an estimated 10,000 people, including Gabezech and her family, were left homeless after residents of a neighboring village set fire to their houses. "I didn't see the fire, I only saw the smoke," Gabezech says. "We walked a long way to get here ... I was carried. I was tired. There were many people who lost their homes in the fires, just like us."
UNICEF is working to improve the dire conditions in the often overcrowded IDP sites, where malnutrition and diseases like diarrhea, pneumonia, scabies and eye infections are common and the only water source is a nearby stream. UNICEF is supplying families with water treatment tablets to prevent diarrhea, a leading cause of death among children under 5.
Two schools in Kusume were damaged in the violence. COVID-19 had already caused massive disruption to children's education in Ethiopia; a combination of violence and the pandemic means that many children have been out of school for more than a year.
"I love to learn," Gabezech says wistfully. "I was in Grade Zero."
UNICEF is working with partners around the world to protect children from the impact of violence, poverty and the COVID-19 pandemic. You can help.

Appearance and Size Facts
- Dark brown in color and are somewhat cylindrical in shape
- Prolonged head with a distinct thin snout extending downward from the head
- Well marked thorax.
- Size: Approximately 1/8-inch long
- Internal feeders and cannot fly
Behavior and Habitat of Granary Weevils
Granary weevils are internal feeders and they cannot fly. When disturbed, Granary weevils play dead by drawing their legs close to their body. They then lie still for several minutes before resuming movement.
The female uses her strong mandibles to chew a small hole in a grain kernel, where she deposits a single egg in the hole and seals it with a gelatinous fluid. In warm weather, the granary weevil can develop from egg to adult in about five weeks. Cold weather prolongs development.
Granary weevils are similar to Rice weevils and they are both often referred to as the Snout weevils. They penetrate and feed on the internal portions of whole grains during the larval stage. Granary weevils are usually found in grain storage facilities, food processing plants, and whole foods markets. They will also infest old pasta, table beans, acorns, chestnuts, birdseed, sunflower seeds, and ornamental corn.
Signs of Infestation of Granary Weevils
The Granary and Rice weevils are the most economically significant pests of stored grain. Damage to grain products will be severe, as the larvae develop inside the grain kernels. Wheat, corn, macaroni, oats, barley, sorghum, Kaffir seed, and buckwheat are just some of the grains and products these weevils destroy.
Tips for Prevention of Granary Weevils
Discard any infested foods, vacuum pantry shelves, cracks, and crevices and make sure to dispose of garbage and vacuum bags outside, away from the home, wipe shelves with white vinegar.


There are 2 main classifications standards that are used today in the western world to diagnose psychopathological symptoms.
In the field psychotherapy, the concept of diagnostics is controversial. The reason being that unlike some physical problems, psychological issues are individual. For example, there is no one single cause of borderline personality disorder (BPD), but an array of situations that occur in the patient’s life that leads up to the symptoms. Diagnosing the symptoms are also complex, since each patient has his/her own way of dealing with the psychological trauma that leads to the condition. However putting labels onto observable psychological and behavioral conditions are necessary for professional to communicate with administrative bodies like psychiatrists, insurance companies, the courts, etc.
The ICD-10 by the World Health Organization (WHO)
The ICD-1o is also known as the International Statistical Classification of Diseases. It is the most recognized diagnostic classification system in the medical profession, and is provided by the WHO.
In the ICD-10 classification of mental disorders (or psychopathology) is categorized in Chapter F. Click here to have a complete online list of the ICD-10 classification of mental disorders.

Post Traumatic Stress Disorder (PTSD) is one of those mental health illnesses that many suffer from and have no idea trauma is present. It looks different for everyone, and I want to take the time to give you a glimpse into the invisible trauma that has many faces.
Mayo Clinic describes PTSD as a mental health condition triggered by a terrifying event, either experienced or witnessed by an individual. When I look at the medical definition, I realized how broad this mental illness truly is.
After much research, I have discovered that symptoms come in many forms and range from intrusive thoughts to nightmares and reliving the traumatic event as if it were happening again.
I suffered from PTSD after my mother’s death, and to this day, certain times of year set the memories in motion. It could be a date, a scent even a specific food. Through therapy and doing my research, I have learned that the key is not to avoid feeling but to move through it.
I want you to examine your own life and situations you have encountered in hopes that you can recognize if you have PTSD. The severity depends on your experience and medical diagnosis.
- Lost a loved one
- Have been in or witnessed an accident
- Have been physically or verbally abused
- Being threatened with a weapon
- Witnessed someone else experience physical or verbal abused
- Have been sexually assaulted
- Combat exposure (Military, first responders, etc.)
The list could continue, but I want you to know help is always available, and you don’t need to deal with this on your own.
There are steps you can take to begin your journey to healing:
- Research PTSD symptoms and risk factors
- See a Therapist for medical diagnosis and treatment
- Follow your treatment plan
- Consider a support group
- Spend time with those who support you
- Be honest with yourself about what you have been through


I have been investigating the BAM method of LED dimming. There are already many microcontroller programs written to control a LED or multiple LEDs with BAM, however I wanted to fully understand the method so I threw together some SPIN code to prove it would work. Click the Read more link for details on the code.
This is the main output loop. It reads the variable "bam" and turns the output (pin 16) on if that bit of the variable is a 1. It repeats each bit of the variable a different number of times to keep the output on longer for the bits that represent a larger number. By doing so it can keep the LED an practically any brightness level.
Since the propeller has multiple cogs this loop can run in a cog completely separate from the code that will calculate what value the variable needs to be to provide the proper output.
In order to test the main loop I created a simple fade in and out sequence that slowly turns the LED on, and then turns the LED off in a slightly faster manner.
You can download the code below.

Melchior de Hondecoeter was a painter who specialised in depicting birds of all types. He began his training with his father Gijsbert, who also painted animals, as did his grandfather Gillis. Hondecoeter continued his training with his uncle, the famous artist Jan Baptist Weenix, whose technique and use of colour is evident in his own style. A perceptive observer, Hondecoeter generally depicted domestic and wild birds, painted with great accuracy with regard to their plumage and with subtle nuances and a mastery of textures that won him great renown. His skill in this genre is evident in his marvellous studies of the birds’ movements as they walk, turn, fight, eat, scavenge or simply stand immobile against a landscape background. This type of painting was highly appreciated in its day and was purchased to decorate middle-class mansions and aristocratic country residences. Among Hondecoeter’s most prominent clients was the Stadtholder William III, who commissioned a canvas for his hunting lodge depicting a Pelican and other Birds by a Reservoir (Rijksmuseum, Amsterdam).

The goal of every company is to operate efficiently to meet customer needs. The amount of complexity and intricacy of various processes within an organization causes chaos and disorganization. It is crucial that business processes run smoothly and efficiently. In this article, you will learn how to optimize your business processes using the process mapping method to increase the efficiency of your organization.
What exactly are business processes, and how should they be designed?
A business process is a set of tasks or activities performed simultaneously or sequentially by people or computer systems within an organization. Business processes add value to the organization and help achieve business goals. For an organization to operate effectively, all business processes should have a clearly established framework. A structured process consists of activities that are situated in time and space. Each business process should be an element of the organizational structure.
What is the business process mapping method?
The business process mapping method involves identifying how an organization operates. Everything that happens in the different parts of the company is defined by the processes operating within them and their interrelationships. By using the mapping method, processes are reviewed. Process gaps, bottlenecks, and places where processes are duplicated, unnecessarily involving limited company resources, are discovered. As a result of process mapping, a clear picture is created to help manage effectively and create space for productivity growth. Information is gathered through interview, observation or process documentation available in the organization.
What can be learned through process mapping?
During business process mapping, we get information about processes in the company that are inefficient and should be optimized. Typically, we get information about the difference between the declared process flow and its actual result. During process mapping, all the inefficiency problems come to the surface. Business process mapping is the foundation for optimization and improvements in a company. Knowing the problems in the processes, we can proceed to eliminate them or improve their speed and efficiency.
Business process mapping is the start to increasing efficiency, freeing up resources and eliminating bottlenecks in the organization. Controlling the business processes that occur helps you manage your business effectively.

Henna is an ink that is gotten from a specific plant called Henna tree. The henna design on the skin is widely known to be done on women from India, Pakistan and other Arab countries. Some people do not believe that it is also done by Africans.
Henna in African tradition has a very old date – as long as 4000 years ago when the practice began. This shows that it is nothing new to Africans. In Nigeria, the Henna plant is grown in different parts of the country. In these different parts, it is also known to have different names. The names come from the different tribes and countries in the African continent for example, in Nigeria, Henna is called Marandaa among the Northern Nigerians while the Yoruba people call it Laali.
Henna is known to be medicinal in various ways. When applied on the skin, it helps the hair on the lady’s skin to be soft. Besides this, Henna helps to improve the immune system of people with sicklecell anaemia – it acts as an anti-sickling substance.
The Henna dye that the plant produces is majorly used by Islamic Nigerians to decorate their body, especially the women. During marriage, the henna dye decorates the women’s skin. It is done to symbolize several things, for example it means good fortune in a woman’s marriage.


Hyper Raman Scattering
Definition: Raman scattering processes involving two pump photons
More general term: Raman scattering
Author: Dr. Rüdiger Paschotta
How to cite the article; suggest additional literature
Hyper Raman scattering is a modified version of Raman scattering, where the scattered light occurs at optical frequencies somewhat lower than twice the frequency of the pump light. This means that two pump photons are converted into one photon of Raman scattered light and one phonon.
This effect is usually fairly weak, but it has aspects which make it interesting for Raman spectroscopy. In particular, hyper-Raman spectra can provide vibrational information on molecules where ordinary Raman scattering is suppressed due to symmetry issues (silent modes, non Raman-active modes). The scattering rate can be substantially enhanced near optical surfaces.

The design of structural steel connections in North America is governed by the AISC 360-10 specification for structural steel buildings. The same limit states apply for the design of connections as any other structural member. The main principal is that no serviceability limit state is exceeeded when the structure is subjected to all appropriate load combinations (whether that be norminal strength under LRFD or allowable strength under ASD). Chapter J of the manual focuses on the general design of connections, whilst chapter K focuses on the design of HSS and box member connections.
Connections can be categorized as shear connections (also known as simple connections) or moment connections based on their ability to transmit moment. Shear connections transmit a negligable moment, whereas moment connections transfer moments with an assumed negligable rotation between the connecting members. Furthermore, the parent member (also known as the supporting member) and child members (also known as the supported members) also act as a way to categorize connection types based on their cross section geometry. This section of the documentation will focus on HSS to W connections which have a HSS (Hollow Structural Section) parent member, and 1 or more W (wide flange) beams.
These connections are normally used in structures that have low load bearing or to minimize the weight of the structure. Common structures that use HSS to W connections are warehouses, hangars, and airplane landing gear. The weakest factor of a HSS shape in a structure is its tendency to buckle under load and thus it is recommended to not reduce the overall strength of the HSS member by adding a connection. As such, the AISC code tried to minimise the material damage done by adding a connection to the HSS member and to achieve the most accurate results, it is recommended to use only AISC specified shapes for the AISC calculations. In industry, the choice of connection is normally governed by its cost and capability to be properly erected. There are three main types of HSS shape that the AISC manual offers which are rectangular, square and round HSS which are shown below.


Unveiling hidden migration and mobility patterns in climate stressed regions: A longitudinal study of six million anonymous mobile phone users in Bangladesh
In Bangladesh, climate resilience is a major concern due to the country’s vulnerability to cyclones combined with sea-level rise that is occurring faster than global averages, exposing roughly 20.5 million people to the risk of inundation by 2050. In this and similar contexts, data on migration and displacement are especially critical to provide for appropriate and timely humanitarian support; however, short-term human mobility is extremely hard to quantify using conventional survey-based research. This project investigates the potential of using mobile phone data to supplement survey data in order to gain a better and faster understanding of voluntary and forced internal population movements caused by climate change.
This project demonstrates that mobile network data can supplement current survey-based approaches to monitor, interpret and respond to migration caused by climate change, both with regard to extreme weather and slow-onset climatic stressors. Mobile network call detail records (CDRs) come in an industry standard format, which contains the location of the closest mobile phone tower at the time of each call, text message or data download. With these data, the research team was able to concurrently quantify incidence, direction, duration and seasonality of migration episodes in Bangladesh. The project shows, for instance, that there is a strong positive association between the number of individuals and the distance that people are moving. However, there is an unexpectedly weak negative correlation between in- and out-migration of specific regions; while people generally left their affected districts after the cyclone, some stayed or even moved into these areas. This means that one may only cautiously assume that increased out-migration means a net loss of population at the same time, and that it is advisable to complement analyses with assessments of changes in in-migration rates. Overall, this study has demonstrated that using mobile phone data is a valuable supplement to survey data sources in order to gain detailed national level insights on (forced) population movements. Potentially, this approach can be replicated for every region that is covered by services of mobile network operators.

- After ten years the court and the schools /
- The 1954 Brown vs. Board of Education of Topeka ruling made it clear that segregation would not be tolerated and that states must comply with federal law. In this program, filmed ten years after Brown, news correspondents report on the mixed progress made toward integrating public schools in Nashville, New Rochelle, New Orleans and Prince Edward County, Virginia. Stumbling blocks such as faculty segregation, busing and segregational zoning are examined. A discussion featuring Attorney General Robert Kennedy, Georgia Governor Carl Sanders and Ex-Secretary of the NAACP, Roy Wilkins concludes the program.

- Black power, white backlash
- When the radical wing of the civil rights movement began equating redress with rebellion rather than nonviolent protest, "Black power" became the rallying cry. In this program, filmed in 1966, Mike Wallace explores public sentiment during that turbulent period by assessing the attitudes, opinions and reactions on both sides of the color line. Interviews with major figures of the movement discussing black militancy, economic power, fair housing, nonviolence, and the tensions in Cicero, Illinois, the Selma of the North capture the fervor of 1966.

Issyk-Kul is the second-largest lake in the world © Novoselov, Shutterstock
The second largest in the world, the waters of this unique alpine lake can never freeze.
Lake Issyk-Kul, the second-largest alpine lake in the world (Lake Titicaca in Peru/Bolivia is the largest), gives its name to the oblast that surrounds the lake’s shoreline and extends across the high Tien Shan range south to the Chinese border. Issyk-Kul Oblast, which in area makes up around 20% of Kyrgyzstan’s territory, has a population of less than 500,000, the vast majority of whom live around the lake’s shores.
The lake’s name, which is also spelled Ysyk Kol or Issyk-kol, means literally ‘warm lake’ in the Kyrgyz language, as does its Chinese equivalent, Ze-Hai. There is good reason for this: in a part of the world where winter temperatures can plummet to -25°C or worse, the shores of the lake have a microclimate that is relatively balmy and, even more aptly, its waters never freeze. This is all the more surprising considering the lake stands at considerable altitude – 1,606m above sea level. Scientists have long debated the precise mechanics of this, and it would seem it is down to a combination of deep-water physics, slight salinity and underground thermal activity. Most locals are less questioning and are merely grateful for the respite the lake offers, assuming it is because the water is warmed by heat wafting up from the earth’s core.


Homeopathy is a medical science introduced by German scientist Dr. Samuel Hahnemann. It is the most practiced alternative system of medicine used by over 200 million people worldwide. It works effectively for acute, chronic and recurring diseases. Homeopathy is holistic because it treats the person as a whole, rather than focusing on a diseased part or a labeled sickness.
Homeopathy works on the principle that our body constantly makes effort to maintain and re-establish the internal stability. So when the body is in the state of sickness, Homeopathic medicine gently provides stimulation to the immune system of our body and to fight the disease out of our body. Homeopathic physicians seek to cure their patient on physical, mental and memotional levels, and each treatment is tailored to a patient’s individual needs.
Homeopathic medicines are prepared from a wide range of natural sources. So homeopathic medicines are safe and have no side effects. This means when used appropriately under the guidance of a qualified homeopath they can be taken by people of all ages including infants,children and pregnant or breast feeding women.
Homeopathy can treat conditions like allergic diseases, migraine, sinusititis, skin diseaseslike eczema, psoriasis, corns, warts, hair fall, hormonal imbalances, PCOD, menstrunal irregularities, thyroid complaints, kidney stones, gastrointestinal disorder, arthritis,recurrent infections in children like adenoids, tonsillitis etc.


Wonhyo is probably Korea’s best loved Buddhist saint, and someone who earned that title by the depth of his insight, and the compassionate way he returned to teach after attaining Enlightenment.
In the 13th century, together with another monk, Wonhyo set out on a journey, or a pilgrimage, that would take him from one coast to the other in the Silla kingdom of Korea. When he arrived at his destination he lived in a cave, and it was there that he had his breakthrough.
One night he found himself thirsty and picking up what he thought was a bowl, he scooped up some water and drank it. It was so sweet and refreshing. In the morning though, he found he had drunk muddy water from a human skull and was repulsed. Understanding that all things originate with mind he awakened.
A Canadian journalist, Tony MacGregor, who had been living in Korea for some time, came across Wonhyo’s story and decided to retrace his steps, in an attempt to understand what Wonhyo had understood. This film follows his journey as he explores Korean Buddhism and its meanings.
This is the first in a series of films from Korea with Buddhist themes, although the ones that follow are movies rather than documentaries, and explore their motifs with Korean Buddhism as the backdrop.

Types of holding companies
A company which acquires more than 50% equity shares of any other company in order to control the composition of its board of directors, it is called holding company. Holding company’s main aim is to eliminate the competition, to achieve the economies of production and to obtain the economies of management.
Advantages of holding company
1) Less investment is required for acquiring interest in another company.
2) Both the companies enjoy the benefits of monopoly.
3) Each company has to prepare its own books of account which helps in knowing the financial position of the company.
4) The subsidiary company does not liquidate it continues to operate.
There are some disadvantages of holding company also and these are:
1) There is the possibility of fraud by holding company.
2) There are the chances where subsidiary company may be forced to appoint a person as director of the choice of holding company.
Different types of holding company
1) Pure holding company: a company which holds majority shares of another company.
2) Off spring: a new company is formed to take over the share of existing company.
3) Intermediate holding company: a holding company which itself is the subsidiary of another company.
4) Mixed or operating holding company: it is the company which controls another company only for financial gains.


Hypoglycemia, commonly caused by inadequate diet, is compounded by stress. Glucose is needed by every cell in the body as a source of energy. When the blood sugar level drops too low in any particular organ or gland, it can no longer function in a balanced manner. While sugars and other simple refined carbohydrates create rapid rises in blood sugar levels (and the accompanying insulin spike!), eating complex carbohydrates (whole grains, beans, fruits, vegetables, etc.) can ease these rapid swings.
Certain nutrient components, in particular, can have a positive effect on supporting healthy blood sugar management. LBS-39 Nutrient Support Concentrate, was specially created to support people blood sugar levels that are already within the normal range.
Some of the nutrients in LBS-39 are vitamins A, B-1, B-2, B-5, B-6, B-12, inositol, niacinamide, biotin, vitamins C and E, folic acid, PABA, chelated forms of calcium, magnesium, manganese, iodine, chromium, zinc and choline, as well as other glandular support nutrients.
Zinc is closely involved in the body's use of insulin. Zinc is plentiful in the healthy pancreas, where insulin is manufactured and is a constituent of insulin. Chromium, an extremely important trace mineral in LBS-39 is also known as Glucose Tolerance Factor because it is crucial for proper regulation of blood sugar. Chromium is a cofactor in insulin's regulation of sugar uptake by the cells.
Do you want to know more about healthy blood sugar management and its possible health benefits? If so, see your doctor... and ask him or her about the nutritional support provided by LBS-39!†

Measuring electrical activity not detected by plain ECG
This is a detailed type of electrocardiogram (ECG or EKG) that detects abnormalities in electrical conduction of the heart that a traditional ECG would not be able to detect. The signal-averaged electrocardiogram or SAECG is a noninvasive way to test heart function and also predict risk of a serious cardiac event. It can also be a predictor of future cardiac events after a person has had a heart attack. It may be useful for patients with conditions such as heart failure or cardiomyopathy who are at high risk for sudden cardiac death or ventricular arrhythmia.
Similar to a traditional ECG, small patches (electrodes) are placed at certain spots on the legs, arms and chest. The electrodes have wires that are connected to a machine that picks up the electrical activity of the heart. The machine records the electrical signals and patterns and the doctor examines the electrical activity. The test is painless and involves no special preparation. You may feel slight discomfort when the patches are removed from the skin and there may be minor skin irritation where the patches were.
SAECG is an outpatient procedure so you can go home afterwards and resume regular activity as soon as you like. Your doctor will discuss the results of the report with you and make any additional testing or treatment recommendations.


One of the most important ways to control weight is to change your diet. While it’s not a quick fix, losing excess weight can improve a variety of health conditions. The process may take months, or even years, but the improved physical and psychological health is usually worth the effort. A few healthy habits you can begin today can help you get on the road to a healthier weight.
Eat foods high in fiber. Fiber helps slow the digestive process and helps curb your appetite. Also, fruits and vegetables are high in water, which can help you feel full with fewer calories. Adding these foods to your diet can help you maintain a healthy weight. While you’re at it, try limiting your intake of high-calorie foods.
The health community uses the term energy balance to describe the art of eating only the right amount of food for your body. This concept applies to all types of people, regardless of their current weight. While there’s no single standard of “healthy” weight, a higher degree of self-control is generally linked with better health.
Eating a healthy diet and getting plenty of exercise are vital to maintaining a healthy weight. Managing your stress and eating mindfully are also important ways to control your weight. These habits will allow you to maintain a healthy weight and prevent obesity. Even if you’re not a fan of exercise, these habits will help you keep your weight stable.
The most common ways to control weight are to exercise and eat fewer calories. A few other popular weight-control behaviors include eating less, fasting for 24 hours, and changing your eating habits. For example, a diet that focuses on one food can be very effective at reducing your calories. However, some people simply can’t control their weight without exercising.
Studies show that the prevalence of obesity has doubled since the mid-1980s. Even the normal-weight population is increasingly concerned about the risks associated with excessive weight. Weight regulation is not easy, and the majority of people aren’t successful at it. This means that health authorities must find ways to control weight in a healthy population without exacerbating existing health problems.


How Do I Become a Geography Tutor?
You will need an extensive background in geography or geography concepts in order to become a geography tutor, but if you are a student yourself, don't worry; you may still be able to become a tutor at your school. You will need to decide if you want to volunteer your services or if you intend to get paid, as this may affect the steps you need to take to become a geography tutor. Regardless of what type of tutoring you intend to offer, it is important that you build your credentials and write a resume to show to potential students in need of your help.
Professional tutors should have a college degree or must be working toward one. You can earn a degree in geography or a related field in order to become a geography tutor. If you are still a student, you may be able to get jobs as a tutor for lower level students only; a college student can, for example, tutor high school students or even other college students who are enrolled in lower level classes. If you want to become a geography tutor for upper level college students, however, you will either need to have a degree already, or you will need to demonstrate exceptional knowledge and skills in that area.
You can become a geography tutor online as well. Various tutoring agencies will hire experts in various fields, and they will set you up with clients who are in need of tutoring services. You will probably get paid an hourly wage, but you will have to do little work to find clients and set up appointments. If you choose to become a geography tutor independently, you will need to actively seek out clients yourself, which can be more work. One way to do so is to contact local schools, specifically science and history departments, and give your contact information. Teachers or administrators may be able to refer students to you if they are impressed with your credentials.
You can also be hired by an educational institution to become a geography tutor exclusively for that school. In this case, students in need of extra guidance outside the classroom will be referred to you directly from a teacher. You will have the advantage of being able to talk to that student's teacher about developing a tutoring plan, but you may be limited in your scheduling abilities, as tutoring sessions may need to take place during school hours or immediately after school.
Tutoring is very enjoyable for those people who love to share their knowledge.

Of the 10 countries with the highest homicide rates, eight are in Latin America and the Caribbean. The region is likewise home to 34 of the world’s 50 most violent cities. The social and economic impacts of those levels of crime are massive, and, as a result, governments and private sectors in Mexico, Brazil and, more recently, Guatemala and El Salvador are looking for new solutions. They have sought advice from two familiar sources in American policing: former New York City Mayor Rudy Giuliani and current New York City Police Commissioner William Bratton.
Giuliani, and even more so Bratton, are known for their application of the “broken windows” model of policing that many credit with helping to reduce crime across much of the United States over the past 20 years. If done properly and in combination with other reforms—such as purging corrupt police officers and members of the judiciary and adopting management models of accountability like CompStat, the computerized system developed in New York to track crime and officers’ beats—the broken windows model of policing can contribute to improving the security situation in Latin America.
Broken windows policing is based on a theory expounded by two college professors, George L. Kelling and James Q. Wilson, in an article in The Atlantic in 1982. Kelling and Wilson connected smaller acts of public disorder, like graffiti and public drinking, to more serious crime. Bratton and his disciples spread these policing methods across the U.S., implementing them most prominently in New York City in the early 1990s, where levels of crime and disorder plummeted. Today, crime rates in U.S. cities, many of which used some form of the broken windows policing, including Washington, D.C. and Los Angeles, are nearing 50-year lows.

Riding a side saddle, or as was once known a “seat-back” is an old English riding technique that requires the rider to be seated forward in the saddle at an angle. Side saddles are commonly used for hunting and can also help riders maintain stability while on long rides.
A side saddle is a piece of equipment that allows riders to sit on the horse’s off-side. It is usually made from wood or metal, and it can be used for riding in both directions. Read more in detail here: what does a side saddle look like.
How do you sit on a side saddle?
A: The side saddle is a saddle that sits on the horses near hindquarters and is used to increase the riders control of the horse. It is usually placed on the left or right side, depending on which hand the rider uses to hold onto the reins.
Is Side saddle bad for horses?
A: Side saddle is a type of saddle that allows the rider to sit sideways on the horse. This can be beneficial for riders who are not as tall or have difficulty mounting and dismounting from the regular saddle.
Side saddles are the most common type of saddle that riders use. They are typically used for riding on the left side of the horse. Reference: side saddle for sale.

How far can wood joists span?
Floor joist span is the length of an individual joist, from the foundation walls to an interior beam. The spacing between joists is typically 16”, but can also be 12”, 20”, and 24”. The spacing and ability to span a greater – or smaller – distance is dependent on the size of lumber used for the joists.
How far can joists span without support?
But first, generally, how far can a 2×8 span without support? Depending on various factors, the maximum span for a 2×8 floor joist is 16′ 6”. The maximum span for roof rafters is 23′ 9”. For headers, the maximum span is 11′ 2”.
How long can a timber beam span?
Changing to 600mm centres will change the span distances for the same timber sizes.
|Joist size (mm)||Max span (metres)|
|47 x 95||1.47||1.70|
|38 x 220||3.54||3.95|
|47 x 220||3.81||4.25|
What is the largest span all wood I joists are available for?
IRC covers the maximum span length of wood joists, from 2×6 to 2×12 or greater. IRC also specifies floor joist sizing and spans depending on the joist spacing, commonly 16 inches on center but can vary from 12 to 24 inches apart.
What size beam do I need for a 14 foot span?
Thus, for a 14 foot span, you will need atleast 3-2×12 or 6×12 size of wood beam. For a 14-foot spans, the wood beam has to be at least 12 inches in depth and 6″ in width (3-2×12) used for residential building, wood frame structure or projects.
What joist can span 20 feet?
What size i joist to span 20′:- as per general thumb rules and guideline, a 2-5/16″×11-7/8″ size of i joists made of engineered wood can allows spans up to 20 feet for a live load of 40 pounds per square foot and dead load of 10 pounds per square foot when spaced 16 inches apart.


Researchers from the University of California, Los Angeles (UCLA) and the University of Toronto have partnered to devise a new non-invasive diagnostic test for prostate cancer.
The team identified a urine biomarker for aggressive prostate cancer that is expected to aid in deciding an appropriate treatment plan for patients.
With existing screening tools, around 25% to 40% of patients with a clinically insignificant disease undergo unnecessary surgeries and radiotherapy treatments.
The researchers also added that 20% to 35% of men with prostate cancer do not receive enough therapy and often experience disease recurrence.
Commonly, needle biopsy is used to identify prostate cancer, an approach which is considered invasive and associated with a range of clinical risks.
A blood test is a less invasive method but is believed to yield inaccurate results in all cases.
Urine biomarkers are intended to allow non-invasive and accurate differentiation of slow growing tumours and potentially life-threatening cancers, in turn facilitating better treatment decisions.
To identify and develop these biomarkers, the research team used microRNA involved in prostate cancer development and progression, and also affecting treatment response in patients.
The researchers discovered seven stable RNAs and integrated them with machine-learning techniques to create a new biomarker.
UCLA David Geffen School of Medicine urology and human genetics professor Paul Boutros said: “We developed a three-stage experimental strategy that would maximize statistical and data science considerations to give us the best chance of finding a biomarker to predict prostate cancer aggressiveness.”
When assessed in a clinical study, the biomarker was able to identify high-risk individuals, accurately diagnosing 80% of aggressive cancers.
The accuracy of the new test was found to be comparable to that of tissue-based tests.


Teacher Workshops are the talk of the town in recent times. The times are changing, the pattern of teaching is changing and so is the mindset of students. The COVID pandemic made the whole education system and traditional teaching online, few teachers were not ready for the shift. Teacher workshops came as a rescue for them.
Understand and digitize school operations with Teachmint and its features like the performance management for efficient school management.
What are Teacher workshops?
According to Google, the definition of workshops is- A brief intensive course, a seminar, or a series of meetings emphasizing interaction and exchange of information among a usually small number of participants.
Hence it can be said that Teacher Training Workshops are workshops that help the teachers in developing and learning new teaching strategies, strategies of classroom management, technological advancement, etc. In short, the Teacher Training Workshops provide overall continuous growth opportunities to the teachers to make the best use of their abilities.
Understand the difference between B.Ed and BTC. Also read everything about Teachers’ Eligibility Test.
Why are these Workshops important for teachers?
In order to keep moving, be tech-savvy, avoid technological illiteracy and be a student’s favorite, a teacher needs to keep themselves up to date and that is why they say that teaching is a forever learning process and if one is stepping into the profession of teaching they should prepare themselves for being updated. Teacher Training Workshops have got the teacher’s back, many institutes and even government provide these Teacher Training workshop programs to the teachers.
And as Leonardo Da Vinci quotes-
“Learning acquired in youth arrests the evil of old age; and if you understand that old age has wisdom for its food, you will so conduct yourself in youth that your old age will not lack for nourishment”, a teacher should always keep learning.
Happy Teaching and Happy Learning!

Impact of Pandemic Induced Stress on Health Behaviors Related to COVID-19 Susceptibility
University of Tennessee at Chattanooga
Place of Publication
The COVID-19 pandemic has encompassed not only a public health crisis due to the range of symptoms and rapid spread associated with the SARS-CoV-2 virus, but it has also resulted in daily life changes due to public health mandates implemented to reduce the spread of the disease. The current study (N = 148) tested two hypotheses: that individuals experiencing increased stress due to the pandemic would be more likely to engage in protective behaviors that would limit exposure to the virus (e.g., limiting in-person contact) and that individuals experiencing increased stress would also engage in behaviors that may increase their risk for other health concerns (e.g., increased screen time increasing sedentary lifestyles). Using an online survey design with data collected from a college student sample, correlational analyses found that individuals reporting greater levels of stress were more likely to report reduced in-person contact and to identify COVID-19 as a public health threat. Stress did not relate to adherence to safety guidelines, however, considering COVID-19 as a public health threat did. Stress also correlated with increased screen time and caffeine consumption, but not alcohol or nicotine use. The results of the study highlight the importance of assessing both protective and maladaptive health behaviors when researching the relationship between public health concerns and stress.

Now, computer 'fingerprints' may give out your identity, location
Almost like a regular fingerprint, a person's browser fingerprint - or "browserprint" - is often unique to the individual.
MELBOURNE: Unique online 'fingerprints' left behind while using your device in public locations can reveal your identity, and can be used to track your movements, say scientists who are trying to find ways to protect against the fingerprinting of personal computers.
People's leave behind online browser "fingerprints" at each location they visit on their internet browser, researchers said.
Almost like a regular fingerprint, a person's browser fingerprint - or "browserprint" - is often unique to the individual. Such a fingerprint can be monitored, tracked and identified by companies and hackers.
Researchers at the University of Adelaide in Australia are working to find new methods of protecting against the fingerprinting of personal computers - and are now giving members of the community the chance to see their own computer browserprint.
"Fingerprinting on computers is invisible to most people but there are companies out there who are already using these techniques to learn more information about individuals, about their interests and their habits," said Lachlan Kang, PhD student at the University of Adelaide.
"This can be quite powerful information to have, especially if it's used to tailor advertising to you," Kang said.
In countries that are less benign, it could also be used to spy on people, he said.
"Computer users generally are growing in awareness of privacy issues, but currently there's little that can be done to counter fingerprinting," Kang said.
"This is because fingerprints build up in between the websites you're visiting - your browsing history and personal information can be pooled in the gaps between those websites," he said.
"Simply clearing your browsing history won't make any difference to this, because the information is already out there," he added.
Kang is seeking the public's help to better understand which fingerprinting techniques are the most powerful, so that he can help to build defences against them.
"We need to analyse a large number of online fingerprints - as many as 10,000 of them would be helpful. Currently we have 2500, which is a great start," he said.

The General Data Protection Regulation (GDPR) is a regulation in EU law on data protection and privacy for all individuals within the European Union (EU) and the European Economic Area (EEA). It became effective on May 25, 2018, and replaces the 1995 Data Protection Directive.
The GDPR sets out strict rules for how personal data must be collected, processed, and stored by organizations. It gives individuals more control over their personal data and how it's used, and also imposes significant fines on organizations that fail to comply. Key provisions of the GDPR include:
The right to access personal data: Individuals have the right to request access to the personal data an organization holds about them, as well as information about how that data is being used.
The right to rectification: If personal data is inaccurate or incomplete, individuals have the right to have it corrected.
The right to erasure: Also known as the "right to be forgotten," this gives individuals the right to have their personal data deleted in certain circumstances.
The right to restrict processing: Individuals have the right to limit the ways in which their personal data is processed.
The right to data portability: This gives individuals the right to receive their personal data in a machine-readable format, and to request that it be transferred to another organization.
Overall, the GDPR aims to protect the privacy and personal data of individuals within the EU, and to give them more control over how their data is used by organizations.


On June 4th, 2015, the Environmental Protection Agency (EPA) released its draft assessment of the potential impacts of hydraulic fracturing for oil and gas on drinking water resources to the Science Advisory Board for public comment and peer review.
This draft is aimed at providing “available scientific literature and data to assess the potential for hydraulic fracturing for oil and gas to change the quality or quantity of drinking water resources, and identifies factors affecting the frequency or severity of any potential changes.”
In the draft assessment, EPA concluded that “there are above and below ground mechanisms by which hydraulic fracturing activities have the potential to impact drinking water resources . . . includ[ing] water withdrawals in times of, or in areas with, low water availability; spills of hydraulic fracturing fluids and produced water; fracturing directly into underground drinking water resources; below ground migration of liquids and gases; and inadequate treatment and discharge of wastewater.”
EPA, however, determined that there is no evidence that “these mechanisms have led to widespread, systemic impacts on drinking water resources in the United States.” Additionally, EPA found that the number of problems “was small compared to the number of hydraulically fractured wells.”
As part of their assessment, EPA also released twenty peer-reviewed technical research papers the same day.
Further information on EPA’s study of hydraulic fracturing for oil and gas and its potential impact on drinking water resources can be found at http://www2.epa.gov/hfstudy.

Business Economics of the Gig Economy: Opportunities and Challenges
The gig economy, also known as the sharing economy, is a rapidly growing trend in which businesses and individuals rely on a network of independent contractors or freelancers to provide services. This model has the potential to create new opportunities and efficiencies, but also brings a set of new challenges. In this article, we will explore the business economics of the gig economy and the opportunities and challenges it presents.
The gig economy is characterized by a shift away from traditional employment models and towards a more flexible and decentralized workforce. Businesses in the gig economy rely on a network of independent contractors or freelancers, who are not considered employees, to provide services. This model allows for more flexibility and cost savings, as companies can quickly scale up or down based on demand.
One of the main benefits of the gig economy for businesses is the ability to access a larger pool of talent. The gig economy allows companies to tap into a global network of skilled workers, which can be especially useful for businesses in industries such as technology, design, and consulting. This can help to increase productivity, lower costs, and improve time-to-market.
However, the gig economy also presents a set of challenges for businesses. One of the main challenges is the lack of long-term commitment from workers, which can make it difficult for businesses to plan and forecast. Additionally, the gig economy also raises concerns about worker rights and benefits, as independent contractors are not typically eligible for the same protections as traditional employees.
Another challenge for businesses in the gig economy is the regulatory environment. The gig economy is still a relatively new phenomenon, and many governments are still figuring out how to regulate it. This can create uncertainty for businesses and make it difficult to operate in certain regions.
In conclusion, the gig economy presents both opportunities and challenges for businesses. The ability to access a larger pool of talent and lower costs can be beneficial, but the lack of long-term commitment from workers and the regulatory environment can create challenges. As the gig economy continues to grow, it will be important for businesses to find ways to effectively navigate these challenges and take advantage of the opportunities it presents.


Amati and Stradivari violins are highly appreciated by musicians and collectors, but the objective understanding of their acoustic qualities is still lacking. By applying speech analysis techniques, we found early Italian violins to emulate the vocal tract resonances of male singers, comparable to basses or baritones. Stradivari pushed these resonance peaks higher to resemble the shorter vocal tract lengths of tenors or altos. Stradivari violins also exhibit vowel qualities that correspond to lower tongue height and backness. These properties may explain the characteristic brilliance of Stradivari violins. The ideal for violin tone in the Baroque era was to imitate the human voice, and we found that Cremonese violins are capable of producing the formant features of human singers.Abstract
The shape and design of the modern violin are largely influenced by two makers from Cremona, Italy: The instrument was invented by Andrea Amati and then improved by Antonio Stradivari. Although the construction methods of Amati and Stradivari have been carefully examined, the underlying acoustic qualities which contribute to their popularity are little understood. According to Geminiani, a Baroque violinist, the ideal violin tone should “rival the most perfect human voice.” To investigate whether Amati and Stradivari violins produce voice-like features, we recorded the scales of 15 antique Italian violins as well as male and female singers. The frequency response curves are similar between the Andrea Amati violin and human singers, up to ∼4.2 kHz. By linear predictive coding analyses, the first two formants of the Amati exhibit vowel-like qualities (F1/F2 = 503/1,583 Hz), mapping to the central region on the vowel diagram. Its third and fourth formants (F3/F4 = 2,602/3,731 Hz) resemble those produced by male singers. Using F1 to F4 values to estimate the corresponding vocal tract length, we observed that antique Italian violins generally resemble basses/baritones, but Stradivari violins are closer to tenors/altos. Furthermore, the vowel qualities of Stradivari violins show reduced backness and height. The unique formant properties displayed by Stradivari violins may represent the acoustic correlate of their distinctive brilliance perceived by musicians. Our data demonstrate that the pioneering designs of Cremonese violins exhibit voice-like qualities in their acoustic output.

Effects of Marsh Edge Erosion in Coupled Barrier Island-Marsh Systems and Geometric Constraints on Marsh Evolution
Virginia Institute of Marine Science
JGR Earth Surface
Sand washed across barrier islands during storms (called overwash) provides sediment for salt marshes behind those islands, and can allow a marsh which otherwise would drown to grow vertically fast enough to keep up with sea level. We use a barrier island-marsh evolution model (GEOMBEST+) to see what effect marsh edge erosion by waves has on overwash-supported marshes. Consistent with previous research, we find that wave erosion can make marshes more resilient by freeing sediment that can be used elsewhere on the marsh surface. We add that horizontal erosion of the marsh edge provides more sediment per volume eroded than vertical erosion of the marsh surface. This is because the bottom layers of the marsh contain more sediment (that can stay on marsh surfaces), while the surface layers include plant material (that drifts away or decomposes). We also find that when the marsh and bay are keeping up with sea level, expanding or eroding the marsh is the only way to change the volume of the bay, so how fast the marsh is expanding or eroding can be predicted using geometry, knowing only the size of the basin, sea-level-rise rate, and the net rate of sediment import or export.

Charles Xavier Thomas (1785~1870)
While serving in the French army, he built his first Arithmometer, which could perform basic addition, subtraction, multiplication, and division. Patented in France by in 1820 (two patents and two patents of addition in between 1849 and 1851). In 1848 Thomas restarts the development of the machine. It was manufactured from 1851 to 1915, it became the first commercially successful mechanical calculator and was still being used up to World War One (1915).
Thomas “Arithmometer”. Its production debut of 1851 launched the mechanical calculator industry where millions of them were built. It was the first mechanical calculator to gain widespread use, it became a commercial success, till 1915 (World War One).
Thomas was made Chevalier of the Legion d’Honor for his invention of the Arithmometer. This is when he changed his name from “Charles Xavier Thomas” to “M. le Chevalier Thomas, de Colmar” and later simply “Thomas de Colmar”. By the time of his death in 1870, his manufacturing facility had built around 1,000 Arithmometers since it was commercialization in 1852. At the time, the only reliable and dependable calculator enough to be used in places like government agencies, banks, insurance companies and observatories. The manufacturing of the Arithmometer went on for another 40 years until around 1914.
Why the hiatus of more than thirty years in between 1820 to 1851?
In 1819, Thomas de Colmar co-founded a fire insurance company named “Phoenix” which he left quickly because of the lack of support for his new ideas from his partners and shareholders. Ten years later, in 1829, he started the fire insurance company “Le Soleil” that he grew by merger and acquisitions until his death. In 1843 he started another company insurance called “L’Aigle incendie”. By time of his death the “Aigle - Soleil” group was the biggest insurance business in France and he owned 81% of it!. Eighty years later, in 1946, it was nationalized and finally merged with “La National” in 1968 to become the GAN company which is still in business today.
Yes, Thomas was busy starting this insurance business and making money to finance his calculator business venture.

Hoarding is a compulsive tendency to accumulate worthless possessions and an inability to throw anything away. Hoarding distresses families and angers neighbors. Hoarding has received a lot of exposure due to reality television.
Johns Hopkins University released a 2008 scientific study estimating as many as four percent of Americans are hoarders. It’s estimated compulsive hoarding affects approximately 700,000 to 1.4 million people in the US. Many people hoard not to collect or save things but because they fear throwing something away. They may experience anxiety when considering discarding something, so they keep it instead to prevent feeling anxious.
Hoarding cleanup services depend a lot on the type of hoarding. Hoarding magazines is different than hoarding cats or dogs, where animal feces and urine are involved. Hoarding can create a severe health risk during hoarder cleanup in Washington and Oregon. Cleanup technicians risk exposure to serious pathogens such as Hanta virus, Histoplasmosis, and Staph bacteria such as MRSA and E. coli.
We start hoarding cleanup by disposing of unsalvageable materials per local, state, and federal guidelines for hazardous material disposal. Next, we help the customer go through their belongings, deciding which items to keep, donate, or throw away. Finally, we sanitize, clean, and deodorize everything with proven cleaning solutions and techniques to protect property value and restore health and safety.
Call us at 1-877-524-6411 if you need discreet hoarding cleanup or clutter clean-up in Washington and Oregon.

HORIZONTAL CONTROLS & ITS METHODS
The horizontal control consists of reference marks of known plan position, from which salient points of designed structures may be set out. For large structures primary and secondary control points are used. The primary control points are triangulation stations. The secondary control points are reference to the primary control stations.
Reference grids are used for accurate setting out of works of large magnitude. The following types of reference grids are used:
1. Survey Grid
2. Site Grid
3. tructural Grid
4. Secondary Grid
Survey grid is one which is drawn on a survey plan, from the original traverse. Original traverse stations form the control points of the grid. The site grid used by the designer is the one with the help of which actual setting out is done. As far as possible the site grid should be actually the survey grid. All the design points are related in terms of site grid coordinates. The structural grid is used when the structural components of the building are large in numbers and are so positioned that these components cannot be set out from the site grid with sufficient accuracy. The structural grid is set out from the site grid points. The secondary grid is established inside the structure, to establish internal details of the building, which are otherwise not visible directly from the structural grid.

—A river seismic survey technology based on using pneumatic water sources and autonomous seismic recorders, which are installed on the river bank and configured for continuous seismic recording, is developed at the Geophysical Survey of the Russian Academy of Sciences (GS RAS). In recent years, several thousand kilometers of profiles have been developed by the CDP-2D method on the rivers of East Siberia: Lena, Nizhnyaya Tunguska, and Vitim. Previously, only 6- to 10-s seismograms were used to study the structure of the upper part of the Earth’s crust. At the same time, the deep structure of the crust in the vast territories of East Siberia remains poorly understood because of the high cost of research. The river seismic survey data are used on a profile section acquired in the lower reaches of the Lena River to demonstrate the possibility of studying the crustal structure to the full depth, including the Mohorovičić discontinuity. For this purpose, the archival seismic records are reprocessed with the construction of montages of seismograms of increased duration (up to 23 s). The low-amplitude oscillations of reflected waves from deep boundaries are distinguished owing to multiple summation, which is much larger than in conventional seismic surveys. The equipment used in this study has a sufficient dynamic range, and a high multiplicity is achieved by increasing the binning area. Wind noise leads to the inferior quality of time sections of the upper crust but does not worsen the section at great depths, so this material should not be excluded from processing. The river seismic surveys carried out using the technology developed at the GS RAS on the rivers of East Siberia within about 2700 km contain data that make it possible to build deep sections down to the Mohorovičić discontinuity, and this work needs to be done.


Nothing beats the cool, water-filled fruits of watermelon on a hot summer day, but when your watermelon bursts on the vine before you’ve had a chance to harvest, this can be a little disconcerting. So what makes watermelons split in gardens and what can be done about it? Keep reading to find out.
Causes of Watermelon Splits
There are a few causes of watermelon splits. The most common cause for a bursting watermelon is erratic watering. Whether it’s due to poor irrigation practices or drought followed by heavy rain, excessive accumulation of water can put the fruit under a lot of pressure. As with tomato cracking, when the plants absorb too much water too fast, the excess water goes straight to the fruits. Like most fruits, water makes up a large percentage of the fruit. When the soil becomes dry, the fruit forms a tight skin in order to prevent moisture loss. However, once a sudden surge in water returns, the skin expands. As a result, the watermelon bursts.
Another possibility, in addition to water, is heat. Water pressure within the fruit can build up when it gets too hot, causing the melons to split open. One way to help alleviate splitting is by adding straw mulch, which will help retain moisture in the soil and insulate plants. Adding shade covers during excessively hot periods may help too.
Finally, this may be attributed to certain cultivars as well. Some varieties of watermelon may simply be more prone to splitting than others. In fact, many thin-rind types, such as Icebox, have even been nicknamed “exploding melon” for this reason.

Building flourishing cities by connecting built and natural worlds
Geoff Cape is redesigning cities as urban ecosystems where people interact naturally with their environment year-round.
Demonstrating how a valley of bricks can transform into thriving urban environmentalism.
Through decades of mass urbanization, we distanced ourselves from the natural environment.
Many of us live in cities where social isolation is rampant, in the middle of a climate crisis. Geoff Cape finds hope in reconnecting urbanites not only with each other, but also with the natural world. He believes interconnected human and natural ecologies reveal new opportunities for community, culture and biodiversity.
As a kid, Geoff remembers going to his family’s cabin in the middle of the woods in Tweed, Ontario. He spent lots of time in ravines, adventuring in the “deep wilderness.” These experiences would later spark an ambitious project, transforming a Toronto ravine into a thriving hub for environmental innovation.
Geoff laid the foundation for this project in 1991 by launching Evergreen, a non-profit that uses nature as a design principle in city planning and in the development of public spaces. Evergreen targets three learning areas: Learning Grounds works to develop outdoor classrooms for students, Common Grounds transforms public parks and green spaces and Home Grounds educates homeowners about the use of organic processes in home gardening.
Through Learning Grounds, Geoff works with schools across Canada to build natural outdoor spaces where kids can engage in complex imaginative and social play. He engages kids in environmental education by providing over 2,200 participating schools across Canada with expert assistance (planning, design, plant selection and fundraising) and print, video and online resources.
In 2010, Evergreen won a bid to develop the historic Brick Works in Toronto’s Don Valley. It’s since become a demonstration hub for sustainable practices — featuring a massive year-round native plant nursery that employs at-risk youth and ample work spaces for a range of non-profits.

Revisit the symbols < and > and discuss their meaning. Together, choose the car that travelled the furthest from each group. Using those three numbers, ask the children to decide whether the numbers are less than, or more than each other.


The four sentences (labelled 1, 2, 3, 4) given below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequence of the order of the sentences and key in the sequence of the four numbers as your answer.
1. If you’ve seen a little line of text on websites that says something like "customers who bought this also enjoyed that” you have experienced this collaborative filtering firsthand.
2. The problem with these algorithms is that they don’t take into account a host of nuances and circumstances that might interfere with their accuracy.
3. If you just bought a gardening book for your cousin, you might get a flurry of links to books about gardening, recommended just for you! - the algorithm has no way of knowing you hate gardening and only bought the book as a gift.
4. Collaborative filtering is a mathematical algorithm by which correlations and cooccurrences of behaviors are tracked and then used to make recommendations.
Correct Answer: 4123
Statement 1 says "this collaborative filtering". Here "this" refers to a likely preceding statement which explains about collaborative filtering. While statement 1 is an example of collaborative filtering.
Statement 2 starts with "these algorithms". This doesn't look like an opening statement as it describes a certain algorithm ("these").
Statement 3 is explaining about the flaw in the algorithm
Statement 4 makes for a good opening statement
Statement 41 makes a logical block as the example in 1 refers to collaborative filtering of statement 4
Statement 2 must appear soon after the logical block of 41 as it contains the phrase "these algorithms". While statement 2 explains the problem in the algorithm, statement 3 extends the idea of the problem.
Statement 4 : Introduces collaborative filtering
Statement 1 : Given an example of collaborative filtering
Statement 2 : Speaks about the drawback in the algorithm
Statement 3 : Gives an example of the drawback
Hence the logically coherent order is 4123

File Handling in QBASIC
By Notes Vandar
Click here to view all the Questions with solutions of File Handling in QBASIC
File handling in QBasic allows you to read from and write to files using the QBasic programming language. This can be useful for storing and retrieving data, creating and modifying text files, and working with data in a structured format.
To work with files in QBasic, you will need to use the OPEN command to open a file and specify whether you want to read from or write to the file. You can then use PRINT and INPUT commands to read and write data to the file. The LINE INPUT command can be used to read a line of text from a file, and the EOF (end-of-file) function can be used to determine when you have reached the end of the file.
It is important to close a file when you are finished working with it, using the CLOSE command. This releases the resources that were being used by the file and ensures that any changes you made to the file are saved.
Here is an example of how to read a list of names from a file and print them to the screen using QBasic:
OPEN "names.txt" FOR INPUT AS #1 DO WHILE NOT EOF(1) INPUT #1, name PRINT name LOOP CLOSE #1
In this example, the file “names.txt” is opened for input, and the DO WHILE loop reads each line of the file until it reaches the end. The INPUT command reads a line of text from the file, and the PRINT command prints it to the screen.
File handling in QBasic is a useful skill to have, as it allows you to work with data in a flexible and efficient way. It is also an important foundation for many other programming tasks, such as data analysis and database management.


The German aesthetic bears the imprint of a rich tradition that goes back to medieval times. German artists engaged in a variety of media, including sculpture, painting, and printmaking. What stylistic similarities can you observe among Albrecht Dürer’s Title Page: The Mocking of Christ, Viet Stoss’ Saint Paul, Max Thalmann’s Last Supper, and Lucas Cranach’s Fall and Redemption of Man?
Albrecht Dürer (1471–1528) Title Page: The Mocking of Christ (Large Passion)
Purchase/gift from Mahonri M. Young Estate
Workshop of Viet Stoss (1450–1533) Saint Paul
Purchase/gift of Gloria Teichert with funds provided by Jack R. and Mary Lois Wheatley
School of Lucas Cranach (1472–1553) – Fall and Redemption of Man
Gift of Karel Waterman
YOU MAY NOTICE
Both the Dürer and Thalmann works are woodcuts. With the evolution of the printing press, prints were cheaply produced and mass distributed. Dürer was long known as a master of the woodcut medium, and Thalmann’s 20th- century embrace of traditional German methods of art production was therefore no coincidence.
Thalmann’s use of woodcut not only references a long history of printmaking, but also a long tradition of working with natural materials such as wood. Wooden figures like Viet Stoss’ Saint Paul filled altarpieces in Germany during the medieval period.
The thick folds in the drapery of Viet Stoss’ Saint Paul and School of Lucas Cranach’s Fall and Redemption of Man may both have been influenced by the prevalence of textile production in many northern European countries.
