Clarence Madison Dally
Clarence Madison Dally (1865– October 2, 1904) was an American glassblower, noted as an assistant to Thomas Edison in his work on X-rays and as an early victim of radiation dermatitis and its complications. Early life and education Clarence Dally was born in Woodbridge, New Jersey, one of four brothers. He enlisted in the United States Navy at the age of seventeen, and served for six years. Glassblowing After obtaining an honorable discharge he went to work at the Edison Lamp Works in Harrison with his father and brothers as a glassblower. Around 1890 he moved to the Edison Laboratory in West Orange to assist in experiments with the incandescent lamp. Working with Edison Dally was a favored employee of Thomas Edison. He was entrusted to help demonstrate Edison's new fluoroscopic machine at the 1896 National Electric Light Association exhibition. Edison X-ray focus tube Following Röntgen's work on X-rays in 1895, Clarence and his brother Charles worked on the develo ...

Glassblowing
Glassblowing is a glassforming technique that involves inflating molten glass into a bubble (or parison) with the aid of a Blowpipe (tool), blowpipe (or blow tube). A person who blows glass is called a ''glassblower'', ''glassmith'', or ''gaffer''. A ''lampworking, lampworker'' (often also called a glassblower or glassworker) manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of borosilicate glass. Technology Principles As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by introducing a small amount of air into it. That is based on the liquid structure of glass where the atoms are held together by strong chemical bonds in a disordered and random network,Frank, S 1982. Glass and Archaeology.

Lesion
A lesion is any damage or abnormal change in the tissue of an organism, usually caused by disease or trauma. ''Lesion'' is derived from the Latin "injury". Lesions may occur in plants as well as animals. Types There is no designated classification or naming convention for lesions. Since lesions can occur anywhere in the body and the definition of a lesion is so broad, the varieties of lesions are virtually endless. Generally, lesions may be classified by their patterns, their sizes, their locations, or their causes. They can also be named after the person who discovered them. For example, Ghon lesions, which are found in the lungs of those with tuberculosis, are named after the lesion's discoverer, Anton Ghon. The characteristic skin lesions of a varicella zoster virus infection are called '' chickenpox''. Lesions of the teeth are usually called dental caries. Location Lesions are often classified by their tissue types or locations. For example, a "skin lesion" or a " bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Woodbridge Township, New Jersey
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

List Of Civilian Radiation Accidents
This article lists notable civilian accidents involving radioactive materials or involving ionizing radiation from artificial sources such as x-ray tubes and particle accelerators. Accidents related to nuclear power that involve fissile materials are listed at List of civilian nuclear accidents. Military accidents are listed at List of military nuclear accidents. Scope of this article In listing civilian radiation accidents, the following criteria have been followed: # There must be well-attested and substantial health damage, property damage or contamination. # The damage must be related directly to radioactive materials or ionizing radiation from a man-made source, not merely taking place at a facility where such are being used. # To qualify as "civilian", the operation/material must be principally for non-military purposes. # The event is not an event involving fissile material or a nuclear reactor.

Nuclear Labor Issues
Nuclear labor issues exist within the international nuclear power industry and the nuclear weapons production sector worldwide, impacting upon the lives and health of laborers, itinerant workers and their families. A subculture of frequently undocumented workers do the dirty, difficult, and potentially dangerous work shunned by regular employees. They are called in the vernacular Nuclear Nomads, Bio-Robots, Luminizers, Glow Boys, Radium Girls, the Fukushima 50, Liquidators, Atomic Gypsies, Gamma Sponges, Nuclear Gypsies, Genpatsu Gypsies, Nuclear Samurai and Jumpers. When they exceed their allowable radiation exposure limit at a specific facility, they often migrate to a different nuclear facility. The industry implicitly accepts this conduct as it can not operate without these practices. The World Nuclear Association states that the transient workforce of "nuclear gypsies" – casual workers employed by subcontractors – has been "part of the nuclear scene for at least fou ...

New York World
The ''New York World'' was a newspaper published in New York City from 1860 until 1931. The paper played a major role in the history of American newspapers. It was a leading national voice of the Democratic Party. From 1883 to 1911 under publisher Joseph Pulitzer, it was a pioneer in yellow journalism, capturing readers' attention with sensation, sports, sex and scandal and pushing its daily circulation to the one-million mark. It was sold in 1930 and merged into the ''New York World-Telegram''. History Early years The ''World'' was formed in 1860. From 1862 to 1876, it was edited by Manton Marble, who was also its proprietor. During the 1864 United States presidential election, the ''World'' was shut down for three days after it published forged documents purportedly from Abraham Lincoln. Marble, disgusted by the defeat of Samuel Tilden in the 1876 presidential election, sold the paper after the election to a group headed by Thomas A. Scott, the president of the Pennsylva ...

Cancer
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. In the developing world, 15% of cancers are due to infections such as ''Helicobacter pylori'', hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV). These factors act, at least partly, by changing the genes of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediastinal
The mediastinum (from ) is the central compartment of the thoracic cavity. Surrounded by loose connective tissue, it is an undelineated region that contains a group of structures within the thorax, namely the heart and its vessels, the esophagus, the trachea, the phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph nodes of the central chest. Anatomy The mediastinum lies within the thorax and is enclosed on the right and left by pleurae. It is surrounded by the chest wall in front, the lungs to the sides and the spine at the back. It extends from the sternum in front to the vertebral column behind. It contains all the organs of the thorax except the lungs. It is continuous with the loose connective tissue of the neck. The mediastinum can be divided into an upper (or superior) and lower (or inferior) part: * The superior mediastinum starts at the superior thoracic aperture and ends at the thoracic plane. * The inferior mediastinum from this level to the ...

Carcinoma
Carcinoma is a malignancy that develops from epithelial cells. Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal or ectodermal germ layer during embryogenesis. Carcinomas occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and become malignant. It is from the el, καρκίνωμα, translit=karkinoma, lit=sore, ulcer, cancer (itself derived from meaning ''crab''). Classification As of 2004, no simple and comprehensive classification system has been devised and accepted within the scientific community. Traditionally, however, malignancies have generally been classified into various types using a combination of criteria, including: The cell type from which they start; specifically: * Epithelial cells ⇨ carcinoma * Non-hematopoietic mesenchymal cells ⇨ sarcoma * Hematopoietic cells **Bone marrow-de ...
