Accident Sequence Evaluation Program
An accident is an unintended, normally unwanted event that was not deliberately caused by humans. The term ''accident'' implies that the event may have been caused by unrecognized or unaddressed risks. Many researchers, insurers and attorneys who specialize in unintentional injury prefer to avoid using the term ''accident'', and focus on conditions that increase risk of severe injury or that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been directly caused by human error, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car crashes are the result of dangerous behavior and not purely ''accidents''; however, English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Accidental deaths were much less frequent before high-powered machinery began to spread with the Industrial Revolutio ...

Green Bank 300ft Collapsed Telescope
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while re ...

Sports Injury
Sports injuries occur during participation in sports or exercise in general. Globally, around 40% of individuals engage in some form of regular exercise or organized sports, with upwards of 60% of US high school students participating in one or more sports. Sports injuries account for 15 - 20% of annual acute care visits with an incidence of 1.79 - 6.36 injuries per 1,000 hours of participation. Sports injuries can be broken down into the types of injuries, risk factors and prevention and the overall impact that injuries have on athletes. Types of sport injury The type of sports injury suffered varies greatly based on gender, age and sport. Nonetheless, those with the highest prevalence remain contusions, fractures and sprains, followed closely by wounds and overuse injuries. Also common, the possible severity of head and neck injuries are important to consider. It is also paramount to place emphasis on the specific injuries that are most commonly encountered by sports medicine ...

Ferries
A ferry is a boat or ship that transports passengers, and occasionally vehicles and cargo, across a body of water. A small passenger ferry with multiple stops, like those in Venice, Italy, is sometimes referred to as a water taxi or water bus. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Baltic Sea) may also be called ferry services, and many carry vehicles. History The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it could not work and such a ferry, modifie ...

Whitewater Kayaking
Whitewater kayaking is an outdoor adventure sport where paddlers navigate a river in a specially designed kayak. Whitewater kayaking includes several styles: river running, creeking, slalom, playboating, and squirt boating. Each style offers a different way to experience the thrill and beauty of whitewater environments. Various techniques help paddlers navigate rivers, such as paddle strokes (such as ready position, forward stroke, back stroke, low brace, high brace, forward sweep, back sweep, and duffek/bow rudder), rolling, and boofing. Whitewater kayaking requires much essential equipment to make a “kayaking kit,” such as a whitewater-specific kayak, spray skirt, paddle, helmet, and PFD (personal flotation device). Paddling on rivers, lakes, and oceans dates back to the Stone Age, with rafts, catamarans, canoes, and kayaks evolving based on the needs of indigenous peoples. After his North American travels, John MacGregor popularized kayaking in Europe in the 19th centu ...

Refugee Crisis
A refugee crisis can refer to difficulties and/or dangerous situations in the reception of large groups of refugees. These could be Forced displacement, forcibly displaced persons, internally displaced persons, asylum seekers or any other huge groups of migrants. According to the United Nations High Commissioner for Refugees (UNHCR), due to conflicts, human rights violations, and other disturbing events, 108.4 million individuals experienced forced displacement globally by the end of 2022. 35.3 million of 108.4 were refugees. UNHCR oversees 29.4 million refugees, whereas 5.9 million fall under the mandate of UNRWA as Palestine refugees. Furthermore, internal displacement affects 62.5 million individuals, 5.4 million are asylum-seekers, and an additional 5.2 million are other people in need of international protection. More vital information from UNHCR highlights that 76% of refugees and those in need of international protection worldwide are hosted in low to middle-income countr ...

Cruise Ship
Cruise ships are large passenger ships used mainly for vacationing. Unlike ocean liners, which are used for transport, cruise ships typically embark on round-trip voyages to various ports of call, where passengers may go on Tourism, tours known as "shore excursions". Modern cruise ships tend to have less hull strength, speed, and agility compared to ocean liners. However, they have added amenities to cater to water tourism, water tourists, with recent vessels being described as "balcony-laden floating condominiums". there were 302 cruise ships operating worldwide, with a combined capacity of 664,602 passengers. Cruising has become a major part of the tourism industry, with an estimated market of $29.4 billion per year, and over 19 million passengers carried worldwide annually . The industry's rapid growth saw nine or more newly built ships catering to a North American clientele added every year since 2001, as well as others servicing European clientele until the ...

Electric Bike
An electric bicycle, e-bike, electrically assisted pedal cycle, or electrically power assisted cycle is a bicycle with an integrated electric motor used to assist propulsion. Many kinds of e-bikes are available worldwide, but they generally fall into two broad categories: bikes that assist the rider's pedal-power (i.e. pedelecs) and bikes that add a throttle, integrating moped-style functionality. Both retain the ability to be pedaled by the rider and are therefore not electric motorcycles. E-bikes use rechargeable batteries and typically are motor-powered up to . High-powered varieties can often travel up to or more than . Depending on local laws, many e-bikes (e.g., ''pedelecs'') are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles, such as licensing and mandatory safety equipment. E-bikes c ...

IATA
The International Air Transport Association (IATA ) is an airline trade association founded in 1945. IATA has been described as a cartel since, in addition to setting technical standards for airlines, IATA also organized tariff conferences that served as a forum for price fixing. According to IATA, the trade association represents 317 airlines, including major carriers, from over 120 countries. The IATA's member airlines account for carrying approximately 82% (2020) of total available seat miles air traffic. IATA supports airline activity and helps formulate industry policy and standards. It is headquartered in Montreal, Canada, with executive offices in Geneva, Switzerland. History IATA was formed in April 1945 in Havana, Cuba. It is the successor to the International Air Traffic Association, which was formed in 1919 at The Hague, Netherlands. At its founding, IATA consisted of 57 airlines from 31 countries. Much of IATA's early work was technical and IATA provided input to ...

Aviation Safety
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulations and oversight. Aviation security is focused on protecting air travelers, aircraft and infrastructure from intentional harm or disruption, rather than unintentional mishaps. Statistics Evolution Aviation is safer today than it has ever been. Modern commercial aviation boasts an accident rate of approximately 1 fatal accident per 16 million flights, far lower than historic numbers. On December 14, 1903, the Wright Brothers conducted a test flight of their powered airplane from the slope of Big Kill Devil Hill in North Carolina. Upon takeoff, the airplane lifted about 15 feet off the ground, stalled, and crashed into the sand. Only three da ...

Microwave Oven
A microwave oven, or simply microwave, is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces Dipole#Molecular dipoles, polar molecules in the food to rotate and produce thermal energy (heat) in a process known as dielectric heating. Microwave ovens heat food quickly and efficiently because the heating effect is fairly uniform in the outer of a homogeneous, high-water-content food item. The development of the cavity magnetron in the United Kingdom made possible the production of electromagnetic waves of a small enough wavelength (microwaves) to efficiently heat up water molecules. American electrical engineer Percy Spencer is generally credited with developing and patenting the world's first commercial microwave oven, the "Radarange", which was first sold in 1947. He based it on British radar technology which had been developed before and during World War II. Raytheon later licensed its patents ...

Post-it Note
A Post-it note (or sticky note) is a small piece of paper with a re-adherable strip of glue on its back, made for temporarily attaching notes to documents and other surfaces. A low-adhesion, tack pressure-sensitive adhesive allows the notes to be easily attached, removed and even re-posted elsewhere without leaving residue. The Post-it's signature adhesive was discovered accidentally by a scientist at 3M. Originally small yellow squares, Post-it Notes and related products are available in various colors, shapes, sizes and adhesive strengths. As of 2024, there are at least 28 documented colors of Post-it notes. 3M's Post-it has won several awards for its design and innovation. Post-its are versatile and can be used in various settings for various purposes. They are commonly used in classrooms and workplaces but can also be found in art, media, and social media. Post-its have also been used as tools for public engagement and persuasion. Although 3M's patent expired in 1997, the ...
