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] |
Lattice Structure
In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in matter. The smallest group of particles in the material that constitutes this repeating pattern is the unit cell of the structure. The unit cell completely reflects the symmetry and structure of the entire crystal, which is built up by repetitive translation of the unit cell along its principal axes. The translation vectors define the nodes of the Bravais lattice. The lengths of the principal axes, or edges, of the unit cell and the angles between them are the lattice constants, also called ''lattice parameters'' or ''cell parameters''. The symmetry properties of the crystal are described by the concept of space groups. All possible symmetric arrangements of particles ...

Beryllium
Beryllium is a chemical element with the symbol Be and atomic number 4. It is a steel-gray, strong, lightweight and brittle alkaline earth metal. It is a divalent element that occurs naturally only in combination with other elements to form minerals. Notable gemstones high in beryllium include beryl ( aquamarine, emerald) and chrysoberyl. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars, beryllium is depleted as it is fused into heavier elements. Beryllium constitutes about 0.0004 percent by mass of Earth's crust. The world's annual beryllium production of 220 tons is usually manufactured by extraction from the mineral beryl, a difficult process because beryllium bonds strongly to oxygen. In structural applications, the combination of high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of water) ma ...

Annealing (metallurgy)
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooling. In annealing, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to a change in ductility and hardness. As the material cools it recrystallizes. For many alloys, including carbon steel, the crystal grain size and phase composition, which ultimately determine the material properties, are dependent on the heating rate and cooling rate. Hot working or cold working after the annealing process alters the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram, heat treatment can be used to ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graduate Assistant
A graduate assistant serves in a support role at a university, usually while completing post-graduate education. The assistant typically helps professors with instructional responsibilities as teaching assistants or with academic research responsibilities as research assistants, aids coaches with an athletic team, or is employed by other university departments (such as housing or academic advising). Rather than receive hourly wages, GAs are often remunerated in the form of a stipend. Assistantships provide experience for graduate students, increasing their future employment options. This is especially true in U.S. college sports, in which a graduate assistant position is very often the first step on a coach's career ladder. Graduate assistantships are beneficial to the employing university as well because graduate assistants fill positions that would cost the university significantly more to fill with traditional employees. A stipend is a fixed sum of money paid periodically fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honor Society
In the United States, an honor society is a rank organization that recognizes excellence among peers. Numerous societies recognize various fields and circumstances. The Order of the Arrow, for example, is the National Honor Society of the Boy Scouts of America. Chiefly, the term refers to scholastic honor societies, those that recognize students who excel academically or as leaders among their peers, often within a specific academic discipline. Many honor societies invite students to become members based on the scholastic rank (the top x% of a class) and/or grade point averages of those students, either overall, or for classes taken within the discipline for which the honor society provides recognition. In cases where academic achievement would not be an appropriate criterion for membership, other standards are usually required for membership (such as completion of a particular ceremony or training program). It is also common for a scholastic honor society to add a criterion re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phi Beta Kappa Society
The Phi Beta Kappa Society () is the oldest academic honor society in the United States, and the most prestigious, due in part to its long history and academic selectivity. Phi Beta Kappa aims to promote and advocate excellence in the liberal arts and sciences, and to induct the most outstanding students of arts and sciences at only select American colleges and universities. It was founded at the College of William and Mary on December 5, 1776, as the first collegiate Greek-letter fraternity and was among the earliest collegiate fraternal societies. Since its inception, 17 U.S. Presidents, 40 U.S. Supreme Court Justices, and 136 Nobel Laureates have been inducted members. Phi Beta Kappa () stands for ('), which means "Wisdom it. love of knowledgeis the guide it. helmsmanof life". Membership Phi Beta Kappa has chapters in only about 10% of American higher learning institutions, and only about 10% of these schools' Arts and Sciences graduates are invited to join the society.

Savannah Morning News
The ''Savannah Morning News'' is a daily newspaper in Savannah, Georgia. It is published by Gannett. The motto of the paper is "Light of the Coastal Empire and Lowcountry". The paper serves Savannah, its metropolitan area, and parts of South Carolina. History William Tappan Thompson, author of the ''Major Jones'' series of humorous stories, along with John McKinney Cooper as publisher and owner, founded the paper on January 15, 1850 as the ''Daily Morning News''. At the end of the Civil War in 1865, John Cooper was pardoned by President Andrew Johnson allowing him to retain ownership of the paper. Its name was changed to the ''Daily News and Herald'', though Thompson remained as editor. Thompson left the paper in 1867 to travel in Europe. In 1868, Thompson returned and the paper was renamed again to ''The Savannah Daily Morning News'' for one edition, then changed to the current name the following day. In 1870, Joel Chandler Harris, who later went on to write the Uncle Remus t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthur G
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ma ...
