Rodney C. Ewing
Rodney Charles Ewing (September 20, 1946 – July 13, 2024) was an American mineralogist, a materials scientist and a nuclear safety expert whose research was focused on the properties of nuclear materials exposed to radiation and long-term geochemical alterations expected for radioactive waste disposal. He was the Frank Stanton Professor in Nuclear Security at the Center for International Security and Cooperation, a Senior Fellow of the Freeman Spogli Institute for International Studies, a Senior Fellow of the Precourt Institute for Energy, an Affiliate of the Stanford Woods Institute for the Environment, and a professor in the School of Earth, Energy and Environmental Sciences at Stanford University. He was also elected a member of the National Academy of Engineering in 2017 for studies on the long-term behavior of complex ceramic materials to assess their suitability for engineered nuclear waste sequestration.

Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into 3 categories: low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity; intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding; and high-level waste (HLW), which is highly radioactive and hot due to decay heat, thus requiring cooling and shielding. Spent nuclear fuel can be processed in nuclear reprocessing plants. One third of the total amount have already been reprocessed. With nuclear reprocessing 96% of the spent fue ...

Radiation Damage
Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. Radiobiology is the study of the action of ionizing radiation on living things, including the health effects of radiation in humans. High doses of ionizing radiation can cause damage to living tissue such as radiation burning and harmful mutations such as causing cells to become cancerous, and can lead to health problems such as radiation poisoning. Causes This radiation may take several forms: *Cosmic rays and subsequent energetic particles caused by their collision with the atmosphere and other materials. *Radioactive daughter products ( radioisotopes) caused by the collision of cosmic rays with the atmosphere and other materials, including living tissues. *Energetic particle beams from a particle accelerator. *Energetic particles or electro-magnetic radiation (X-rays) released from collisions of such par ...

Metamict
Metamictisation (sometimes called metamictization or metamiction) is a natural process resulting in the gradual and ultimately complete destruction of a mineral's crystal structure, leaving the mineral amorphous. The affected material is therefore described as metamict. Certain minerals occasionally contain interstitial impurities of radioactive elements, and it is the alpha radiation emitted from those compounds that is responsible for degrading a mineral's crystal structure through internal bombardment. The effects of metamictisation are extensive: other than negating any birefringence previously present, the process also lowers a mineral's refractive index, hardness, and its specific gravity. The mineral's colour is also affected: metamict specimens are usually green, brown or blackish. Further, metamictisation diffuses the bands of a mineral's absorption spectrum. Curiously and inexplicably, the one attribute which metamictisation does not alter is dispersion. All metamict mate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biography Edward Henry Kraus was born at Syracuse, New York, on December 1, 1875. His father was John Erhardt Kraus, of German ancestry, and his mother, Rosa Kocher Kraus, was of Swiss descent. After training in the high school of Syracuse, he entered Syracuse University, from which he was graduated as Bachelor of Science in 1896. During the following year he was a graduate student in that university and was also an assistant in chemistry and German. He received the degree of Master of Science at the end of the year. For two years, 1897–1899, he was instructor in German and mineralogy at Syracuse. During 1899–1901 he studied at the University of Munich, and at the end of the period received the degree of ...

25th Infantry Division (United States)
The 25th Infantry Division (nicknamed "Tropic Lightning") is a United States Army division based at Schofield Barracks in Hawaii. The division, which was activated on 1 October 1941 in Hawaii, conducts military operations primarily in the Asia-Pacific region. Its present deployment is composed of light infantry and aviation units. Tropic Lightning soldiers regularly train with other U.S. military branches to practice and maintain joint operations capabilities. The climate and terrain of the Pacific region demands Tropic Lightning soldiers be able to operate in physically demanding and harsh environments. In 2014, the division opened the Jungle_warfare#United_States, Jungle Operations Training Center—the first such school in the Army since the closing of the old Jungle Warfare School at Fort Sherman, Panama Canal Zone. Joint operations and training with partner states herald a new chapter in the history of Tropic Lightning—America's Pacific Division. The division was original ...

Interpreter
Interpreting is translation from a spoken or signed language into another language, usually in real time to facilitate live communication. It is distinguished from the translation of a written text, which can be more deliberative and make use of external resources and tools. The most common two modes of interpreting are simultaneous interpreting, which is done at the time of the exposure to the source language, and consecutive interpreting, which is done at breaks to this exposure. Interpreting is an ancient human activity which predates the invention of writing. History Historiography Research into the various aspects of the history of interpreting is quite new. For as long as most scholarly interest was given to professional conference interpreting, very little academic work was done on the practice of interpreting in history, and until the 1990s, only a few dozen publications were done on it. Considering the amount of interpreting activities that is assumed to have oc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vietnamese Language
Vietnamese () is an Austroasiatic languages, Austroasiatic language Speech, spoken primarily in Vietnam where it is the official language.

Vietnamese is spoken natively by around 86 million people, and as a second language by 11 million people, several times as many as the rest of the Austroasiatic family combined. It is the native language of Vietnamese people, ethnic Vietnamese (Kinh), as well as the second language, second or First language, first language for List of ethnic groups in Vietnam, other ethnicities of Vietnam, and used by Overseas Vietnamese, Vietnamese diaspora in the world.
