Madras, India
Chennai (, ), formerly known as Madras ( the official name until 1996), is the capital city of Tamil Nadu, the southernmost Indian state. The largest city of the state in area and population, Chennai is located on the Coromandel Coast of the Bay of Bengal. According to the 2011 Indian census, Chennai is the sixth-most populous city in the country and forms the fourth-most populous urban agglomeration. The Greater Chennai Corporation is the civic body responsible for the city; it is the oldest city corporation of India, established in 1688—the second oldest in the world after London. The city of Chennai is coterminous with Chennai district, which together with the adjoining suburbs constitutes the Chennai Metropolitan Area, the 36th-largest urban area in the world by population and one of the largest metropolitan economies of India.

Samuel Blum
Samuel E. Blum (August 28, 1920 – January 9, 2013) was an American chemist and physicist. He was a researcher at the Battelle Memorial Institute in Columbus, Ohio, working for government and private companies. He worked with semiconductor materials, which was his specialization until his retirement from IBM Watson Research Center in 1990. Blum's most notable invention is the patent on the ultraviolet excimer laser, which is used in surgical and dental procedures, which provided the laser technology that is central in LASIK (laser-assisted in situ keratomileusis) surgery. The co-inventors included chemist Rangaswamy Srinivasan and physicist James J. Wynne. The patent was filed in December 1982 and was issued on November 15, 1988. The contribution of this technology to LASIK has brought 20/20 vision and freedom from eyeglasses and contact lenses to millions of people. For this innovation, he was inducted to the National Inventors Hall of Fame (2002) and received the R. W. Wood Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. The society publishes more than a dozen scientific journals, including the prestigious '' Physical Review'' and ''Physical Review Letters'', and organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics. Since January 2021 the organization has been led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since. In the early years, virtually the sole activity of the AP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Delbruck Prize
The Max Delbruck Prize, formerly known as the Biological physics prize, is awarded by the Division of Biological Physics of the American Physical Society, to recognize and encourage outstanding achievement in biological physics research. The prize was established in 1981, and renamed for Max Delbrück in 2006. The award consists of $10,000, an allowance for travel to the meeting where the prize is awarded, and a certificate. It was presented biennially in even-numbered years until 2014, and will be presented annually starting 2015.

International Trade Commission
The United States International Trade Commission (USITC or I.T.C.) is an agency of the United States federal government that advises the legislative and executive branches on matters of trade. It is an independent, bipartisan entity that analyzes trade issues such as tariffs and competitiveness and publishes reports. As a quasi-judicial entity, the USITC investigates the impact of imports on U.S. industries, and directs actions against unfair trade practices, such as subsidies; dumping; and intellectual property infringement, including copyright infringement. Background and statutory authority The USITC was established by the U.S. Congress on September 8, 1916, as the U.S. Tariff Commission. In 1974, the name was changed to the U.S. International Trade Commission by section 171 of the Trade Act of 1974. Statutory authority for the USITC's responsibilities is provided by the following legislation: * Tariff Act of 1930 * Agricultural Adjustment Act of 1933 * Trade ...

Astigmatism
Astigmatism is a type of refractive error due to rotational asymmetry in the eye's refractive power. This results in distorted or blurred vision at any distance. Other symptoms can include eyestrain, headaches, and trouble driving at night. Astigmatism often occurs at birth and can change or develop later in life. If it occurs in early life and is left untreated, it may result in amblyopia. The cause of astigmatism is unclear; however, it is believed to be partly related to genetic factors. The underlying mechanism involves an irregular curvature of the cornea and protective reaction changes in the lens of the eye, called lens astigmatism, that has the same mechanism as spasm of accomodation. Diagnosis is by an eye examination called autorefractor keratometry (objective, allows to see lens and cornea components of astigmatism) and subjective refraction, but subjective methods are almost always inaccurate, if lens astigmatism is not fully removed first with a week of e ...

Hyperopia
Far-sightedness, also known as long-sightedness, hypermetropia, or hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred. This blurred effect is due to incoming light being focused behind, instead of on, the retina wall due to insufficient accommodation by the lens. Minor hypermetropia in young patients is usually corrected by their accommodation, without any defects in vision. But, due to this accommodative effort for distant vision, people may complain of eye strain during prolonged reading. Some hypermetropes can see clear at distance, but near vision may be blurred due to insufficient accommodation. For this reason, this defect is referred as far-sightedness. If the hypermetropia is high, there will be defective vision for both distance and near. People may also experience accommodative dysfunction, binocular dysfunction, amblyopia, and strabismus. Newborns are almost invariably hypermetropic, but it gradually decreas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myopia
Near-sightedness, also known as myopia and short-sightedness, is an eye disease where light focuses in front of, instead of on, the retina. As a result, distant objects appear blurry while close objects appear normal. Other symptoms may include headaches and eye strain. Severe near-sightedness is associated with an increased risk of retinal detachment, cataracts, and glaucoma. The underlying mechanism involves the length of the eyeball growing too long or less commonly the lens being too strong. It is a type of refractive error. Diagnosis is by eye examination. Tentative evidence indicates that the risk of near-sightedness can be decreased by having young children spend more time outside. This decrease in risk may be related to natural light exposure. Near-sightedness can be corrected with eyeglasses, contact lenses, or a refractive surgery. Eyeglasses are the easiest and safest method of correction. Contact lenses can provide a wider field of vision, but are associated with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
