Walter E. Fernald State School
The Walter E. Fernald State School, later the Walter E. Fernald Developmental Center, was the Western hemisphere's oldest publicly funded institution serving people with developmental disabilities. Originally a Victorian sanatorium, it became a "poster child" for the American eugenics movement during the 1920s. It later was the scene of medical experiments in the 20th century. Investigations into this research led to new regulations regarding human research in children. The school occupies a property off Trapelo Road in Waltham, Massachusetts. History Early history The Fernald Center, originally called the Experimental School for Teaching and Training Idiotic Children, was founded in Boston by reformer Samuel Gridley Howe in 1848 with a $2,500 appropriation from the Massachusetts State Legislature. The school gradually moved to a new permanent location in Waltham between 1888 and 1891. It would eventually comprise 72 buildings total, located on . At its peak, some 2,500 peo ...

Waltham, Massachusetts
Waltham ( ) is a city in Middlesex County, Massachusetts, United States, and was an early center for the labor movement as well as a major contributor to the American Industrial Revolution. The original home of the Boston Manufacturing Company, the city was a prototype for 19th century industrial city planning, spawning what became known as the Waltham-Lowell system of labor and production. The city is now a center for research and higher education, home to Brandeis University and Bentley University as well as industrial powerhouse Raytheon Technologies. The population was 65,218 at the census in 2020. Waltham has been called "watch city" because of its association with the watch industry. Waltham Watch Company opened its factory in Waltham in 1854 and was the first company to make watches on an assembly line. It won the gold medal in 1876 at the Philadelphia Centennial Exposition. The company produced over 35 million watches, clocks and instruments before it closed in 1957. Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Background Radiation
Background radiation is a measure of the level of ionizing radiation present in the environment at a particular location which is not due to deliberate introduction of radiation sources. Background radiation originates from a variety of sources, both natural and artificial. These include both cosmic radiation and environmental radioactivity from naturally occurring radioactive materials (such as radon and radium), as well as man-made medical X-rays, fallout from nuclear weapons testing and nuclear accidents. Definition Background radiation is defined by the International Atomic Energy Agency as "Dose or dose rate (or an observed measure related to the dose or dose rate) attributable to all sources other than the one(s) specified. So a distinction is made between dose which is already in a location, which is defined here as being "background", and the dose due to a deliberately introduced and specified source. This is important where radiation measurements are taken of a specifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millirem
The roentgen equivalent man (rem) is a CGS unit of equivalent dose, effective dose, and committed dose, which are dose measures used to estimate potential health effects of low levels of ionizing radiation on the human body. Quantities measured in rem are designed to represent the stochastic biological risk of ionizing radiation, which is primarily radiation-induced cancer. These quantities are derived from absorbed dose, which in the CGS system has the unit rad. There is no universally applicable conversion constant from rad to rem; the conversion depends on relative biological effectiveness (RBE). The rem has been defined since 1976 as equal to 0.01 sievert, which is the more commonly used SI unit outside the United States. Earlier definitions going back to 1945 were derived from the roentgen unit, which was named after Wilhelm Röntgen, a German scientist who discovered X-rays. The unit name is misleading, since 1 roentgen actually deposits about 0.96 rem in soft b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advisory Committee On Human Radiation Experiments
The Advisory Committee on Human Radiation Experiments was established in 1994 to investigate questions of the record of the United States government with respect to human radiation experiments. The special committee was created by President Bill Clinton in Executive Order 12891, issued January 15, 1994. Ruth Faden of The Johns Hopkins Berman Institute of Bioethics chaired the committee. The thousand-page final report of the Committee was released in October 1995 at a White House ceremony.Moreno, p. XI Background The scandal first came to public attention in a newsletter called ''Science Trends'' in 1976 and in ''Mother Jones'' magazine in 1981. ''Mother Jones'' reporter Howard Rosenburg used the Freedom of Information Act to gather hundreds of documents to investigate total radiation studies which were done at the Oak Ridge Institute for Nuclear Studies (now the Oak Ridge Institute for Science and Education). The ''Mother Jones'' article triggered a hearing before the Subcommittee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Informed Consent
Informed consent is a principle in medical ethics and medical law, that a patient must have sufficient information and understanding before making decisions about their medical care. Pertinent information may include risks and benefits of treatments, alternative treatments, the patient's role in treatment, and their right to refuse treatment. In most systems, healthcare providers have a legal and ethical responsibility to ensure that a patient's consent is informed. This principle applies more broadly than healthcare intervention, for example to conduct research and to disclosing a person's medical information. Definitions of informed consent vary, and the standard required is generally determined by the state. Informed consent requires a clear appreciation and understanding of the facts, implications, and consequences of an action. To give informed consent, the individual concerned must have adequate reasoning faculties and possess all relevant facts. Impairments to reasoning an ...

Radioisotope
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle (alpha particle or beta particle) from the nucleus. During those processes, the radionuclide is said to undergo radioactive decay. These emissions are considered ionizing radiation because they are energetic enough to liberate an electron from another atom. The radioactive decay can produce a stable nuclide or will sometimes produce a new unstable radionuclide which may undergo further decay. Radioactive decay is a random process at the level of single atoms: it is impossible to predict when one particular atom will decay. However, for a collection of atoms of a single nuclide the decay rate, and thus the half-life (''t''1/2) for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Red Sox
The Boston Red Sox are an American professional baseball team based in Boston. The Red Sox compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. Founded in as one of the American League's eight charter franchises, the Red Sox' home ballpark has been Fenway Park since . The "Red Sox" name was chosen by the team owner, John I. Taylor, , following the lead of previous teams that had been known as the "Boston Red Stockings," including the Boston Braves (now the Atlanta Braves). The team has won nine World Series championships, tied for the third-most of any MLB team, and has played in 13 World Series. Their most recent World Series appearance and win was in . In addition, they won the American League pennant, but were not able to defend their 1903 World Series championship when the New York Giants refused to participate in the 1904 World Series. The Red Sox were a dominant team in the new league, defeating the Pittsburgh Pira ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin ''calx'' "lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and pharma ...

Quaker Oats Company
The Quaker Oats Company, known as Quaker, is an American food conglomerate based in Chicago. It has been owned by PepsiCo since 2001. History Precursor miller companies In the 1850s, Ferdinand Schumacher and Robert Stuart founded oat mills. Schumacher founded the German Mills American Oatmeal Company in Akron, Ohio, and Stuart founded the North Star Mills in Hearst, Rupert's Land. In 1870, Schumacher ran his first known cereal advertisement in the Akron Beacon Journal newspaper. In 1877, the Quaker Mill Company of Ravenna, Ohio was founded. "The name was chosen when Quaker Mill partner Henry Seymour found an encyclopedia article on Quakers and decided that the qualities described — integrity, honesty, purity — provided an appropriate identity for the company's oat product." Quaker Mill Company held the trademark on the Quaker name. In Ravenna, Ohio, on 4 September 1877, Henry Seymour of the Quaker Mill Company applied for the first trademark for a breakfast cereal, "a man ...
