Liquid
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena. Water is by far the most common liquid on Earth. The density of a liquid is usually close to that of a solid, and much higher than that of a gas. Therefore, liquid and solid are both termed condensed matte ...

RMS Titanic
RMS ''Titanic'' was a British passenger liner, operated by the White Star Line, which sank in the North Atlantic Ocean on 15 April 1912 after striking an iceberg during her maiden voyage from Southampton, England, to New York City, United States. Of the estimated 2,224 passengers and crew aboard, more than 1,500 died, making it the deadliest sinking of a single ship up to that time. It remains the deadliest peacetime sinking of a superliner or cruise ship. The disaster drew public attention, provided foundational material for the disaster film genre, and has inspired many artistic works. RMS ''Titanic'' was the largest ship afloat at the time she entered service and the second of three s operated by the White Star Line. She was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, the chief naval architect of the shipyard, died in the disaster. ''Titanic'' was under the command of Captain Edward Smith, who went down with the ship. The ocean liner carri ...

Halomonas Titanicae
''Halomonas titanicae'' is a gram-negative, halophilic species of bacteria which was isolated in 2010 from rusticles recovered from the wreck of the RMS ''Titanic''. It has been estimated by Henrietta Mann, one of the researchers that first isolated it, that the action of microbes like ''Halomonas titanicae'' may bring about the total deterioration of the ''Titanic'' by 2030. While the bacteria have been identified as a potential danger to oil rigs and other man-made objects in the deep sea, they also have the potential to be used in bioremediation to accelerate the decomposition of shipwrecks littering the ocean floor. Cell morphology ''Halomonas titanicae'' is a gram-negative, rod-shaped bacterium that produces peritrichous flagella. It is catalase and oxidase positive. It has been found to form biofilms and some strains are capable of oxidation of thiosulfate, which is regulated by quorum sensing. It is able to withstand high osmotic pressure due to producing molecules like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ectoine
Ectoine (1,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid) is a natural compound found in several species of bacteria. It is a compatible solute which serves as a protective substance by acting as an osmolyte and thus helps organisms survive extreme osmotic stress. Ectoine is found in high concentrations in halophilic microorganisms and confers resistance towards salt and temperature stress. Ectoine was first identified in the microorganism '' Ectothiorhodospira halochloris'', but has since been found in a wide range of Gram-negative and Gram-positive bacteria. Other species of bacteria in which ectoine was found include: * ''Brevibacterium linens'' * '' Halomonas elongata'' * '' Marinococcus halophilus'' * ''Pseudomonas stutzeri'' * ''Halomonas titanicae'' * ''Halorhodospira halophila'' * '' Halomonas ventosae'' Biosynthesis Ectoine is synthesized in three successive enzymatic reactions starting from aspartic β-semialdehyde. The genes involved in the biosynthesis are ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit For Viral Host Cell Interactions
The Unit of Virus Host Interactions (UVHCI) UMI 3265 UJF-EMBL-CNRS was created in Grenoble, France, in January 2007 to develop the collaboration between the Joseph Fourier University, the EMBL Grenoble outstation and the CNRS. The UVHCI was located on the Polygone Scientifique (research campus of the ILL, the ESRF and the EMBL), more specifically in the ILL20 and Carl-Ivar Bränden buildings. The CIBB is shared with the PSB (Partnership for structural biology). The project ended in January 2016, after a period of 9 years. The previous UVHCI teams have been reattached to the (IBS). Its objective was to pursue international standard research in structural and molecular biology, focused, but not exclusively, on virus-host cell interactions and the development of associated techniques. Themes: * Interdisciplinary research covering virus structure, virus assembly and maturation, virus-host cell interactions, host and virus gene expression mechanisms, cell biology of infected cells, in ...

Gamma Rays
A gamma ray, also known as gamma radiation (symbol γ or \gamma), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz (), it imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation ''gamma rays'' based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power. Gamma rays from radioactive decay are in the energy range from a few kiloelectronvolts (keV) to approximately 8 megaelectronvolts (MeV), corresponding to the typical energy levels in nuclei with reasonably long lif ...

Fission Products
Nuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons, the release of heat energy (kinetic energy of the nuclei), and gamma rays. The two smaller nuclei are the ''fission products''. (See also Fission products (by element)). About 0.2% to 0.4% of fissions are ternary fissions, producing a third light nucleus such as helium-4 (90%) or tritium (7%). The fission products themselves are usually unstable and therefore radioactive. Due to being relatively neutron-rich for their atomic number, many of them quickly undergo beta decay. This releases additional energy in the form of beta particles, antineutrinos, and gamma rays. Thus, fission events normally result in beta and gamma radiation, even though this radiation is not produced directly by the fission event itself. The produced radionuclides have vary ...

Inelastic Neutron Scattering
Neutron scattering, the irregular dispersal of free neutrons by matter, can refer to either the naturally occurring physical process itself or to the man-made experimental techniques that use the natural process for investigating materials. The natural/physical phenomenon is of elemental importance in nuclear engineering and the nuclear sciences. Regarding the experimental technique, understanding and manipulating neutron scattering is fundamental to the applications used in crystallography, physics, physical chemistry, biophysics, and materials research. Neutron scattering is practiced at research reactors and spallation neutron sources that provide neutron radiation of varying intensities. Neutron diffraction (elastic scattering) techniques are used for analyzing structures; where inelastic neutron scattering is used in studying atomic vibrations and other excitations. Scattering of fast neutrons "Fast neutrons" (see neutron temperature) have a kinetic energy above ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutron Moderators
In nuclear engineering, a neutron moderator is a medium that reduces the speed of fast neutrons, ideally without capturing any, leaving them as thermal neutrons with only minimal (thermal) kinetic energy. These thermal neutrons are immensely more susceptible than fast neutrons to propagate a nuclear chain reaction of uranium-235 or other fissile isotope by colliding with their atomic nucleus. Water (sometimes called "light water" in this context) is the most commonly used moderator (roughly 75% of the world's reactors). Solid graphite (20% of reactors) and heavy water (5% of reactors) are the main alternatives. Beryllium has also been used in some experimental types, and hydrocarbons have been suggested as another possibility. Moderation Neutrons are normally bound into an atomic nucleus, and do not exist free for long in nature. The unbound neutron has a half-life of 10 minutes and 11 seconds. The release of neutrons from the nucleus requires exceeding the binding energy of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
