Phosphotungstic Acid
Phosphotungstic acid (PTA) or tungstophosphoric acid (TPA), is a heteropoly acid with the chemical formula . It forms hydrates . It is normally isolated as the ''n'' = 24 hydrate but can be desiccated to the hexahydrate (''n'' = 6). EPTA is the name of ethanolic phosphotungstic acid, its alcohol solution used in biology. It has the appearance of small, colorless-grayish or slightly yellow-green crystals, with melting point 89 °C (24 hydrate). It is odorless and soluble in water (200 g/100 ml). It is not especially toxic, but is a mild acidic irritant. The compound is known by a variety of names and acronyms (see 'other names' section of infobox). In these names the "12" or "dodeca" reflects the fact that the anion contains 12 tungsten atoms. Some early workers who did not know the structure called it phospho-24-tungstic acid, formulating it as 3H2O·P2O5 24WO3·59H2O, , which correctly identifies the atomic ratios of P, W and O. This formula was still quoted in papers as late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type Specimen
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost ...

Acetes Sibogae Australis
''Acetes'' is a genus of small shrimp that resemble krill, which is native to the western and central Indo-Pacific, the Atlantic coast of the Americas, Pacific coast of South America and inland waters of South America. Although most are from marine or estuarine habitats, the South American ''A. paraguayensis'' is a fresh water species. Several of its species are important for the production of shrimp paste in Southeast Asia, including '' A. japonicus'', which is the world's most heavily fished species of wild shrimp or prawn in terms of total tonnage. In Southeast Asia, ''Acetes'' have different local names depending on the country. It is known as rebon in Indonesia, geragau in Malaysia, bubuk in Brunei, alamang in the Philippines, among others. Description The genus is characterised by the loss of the fourth and fifth pairs of pereiopods. They are small prawns, long, translucent, but with a pair of black eyes, and a number of red spots of pigment on the uropods. Life cycle Th ...

Glass Shrimp
''Palaemon'' is a genus of caridean shrimp of the family Palaemonidae. The conventional circumscription of the genus ''Palaemon'' is probably paraphyletic. Molecular data suggest that ''Palaemonetes'', as well as the genera ''Exopalaemon'' and '' Couteriella'', are nested within ''Palaemon''. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments. Members The genus contains the following species: *'' Palaemon adspersus'' Rathke, 1837 *''Palaemon affinis'' H. Milne-Edwards, 1837 *''Palaemon capensis'' (De Man ''in'' M. Weber, 1897) *''Palaemon carteri'' (Holthuis, 1950) *''Palaemon concinnus'' Dana, 1852 (mangrove prawn) *''Palaemon curvirostris'' Nguyên, 1992 *''Palaemon debilis'' Dana, 1852 *''Palaemon dolospinus'' Walker & Poore, 2003 *''Palaemon elegans'' Rathke, 1837 (rockpool prawn) *''Palaemon floridanus'' Chace, 1942 (Florida grass shrimp) *''Palaemon gladiator'' Holthuis, 1950 *''Palaemon gracilis'' (Smith, ...

Mantle (mollusc)
The mantle (also known by the Latin word pallium meaning mantle, robe or cloak, adjective pallial) is a significant part of the anatomy of molluscs: it is the dorsal body wall which covers the visceral mass and usually protrudes in the form of flaps well beyond the visceral mass itself. In many species of molluscs the epidermis of the mantle secretes calcium carbonate and conchiolin, and creates a shell. In sea slugs there is a progressive loss of the shell and the mantle becomes the dorsal surface of the animal. The words mantle and pallium both originally meant cloak or cape, see mantle (vesture). This anatomical structure in molluscs often resembles a cloak because in many groups the edges of the mantle, usually referred to as the ''mantle margin'', extend far beyond the main part of the body, forming flaps, double-layered structures which have been adapted for many different uses, including for example, the siphon. Mantle cavity The ''mantle cavity'' is a central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kibibyte
The byte is a units of information, unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character (computing), character of text in a computer and for this reason it is the smallest address space, addressable unit of Computer memory, memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit computing, 8-bit definition, Computer network, network protocol documents such as Internet Protocol, The Internet Protocol () refer to an 8-bit byte as an Octet (computing), octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the Endianness#Bit endianness, bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been Computer hardware, hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six- ...

Lugol's Iodine
Lugol's iodine, also known as aqueous iodine and strong iodine solution, is a solution of potassium iodide with iodine in water. It is a medication and disinfectant used for a number of purposes. Taken by mouth it is used to treat thyrotoxicosis until surgery can be carried out, protect the thyroid gland from radioactive iodine, and to treat iodine deficiency. When applied to the cervix it is used to help in screening for cervical cancer. As a disinfectant it may be applied to small wounds such as a needle stick injury. A small amount may also be used for emergency disinfection of drinking water. Side effects may include allergic reactions, headache, vomiting, and conjunctivitis. Long term use may result in trouble sleeping and depression. It should not typically be used during pregnancy or breastfeeding. Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. Lugol's iodine was first made in 1829 by the French physi ...
