Bacterial Phyla
Bacterial phyla constitute the major lineages of the domain ''Bacteria''. While the exact definition of a bacterial phylum is debated, a popular definition is that a bacterial phylum is a monophyletic lineage of bacteria whose 16S rRNA genes share a pairwise sequence identity of ~75% or less with those of the members of other bacterial phyla. It has been estimated that ~1,300 bacterial phyla exist. As of May 2020, 41 bacterial phyla are formally accepted by the LPSN, 89 bacterial phyla are recognized on thSilva database dozens more have been proposed, and hundreds likely remain to be discovered. As of 2017, approximately 72% of widely recognized bacterial phyla were candidate phyla (i.e. have no cultured representatives). There are no fixed rules to the nomenclature of bacterial phyla. It was proposed that the suffix "-bacteria" be used for phyla. List of bacterial phyla The following is a list of bacterial phyla that have been proposed. Supergroups Despite the unclear ...

Waardenburg Syndrome
Waardenburg syndrome is a group of rare genetic conditions characterised by at least some degree of congenital hearing loss and pigmentation deficiencies, which can include bright blue eyes (or Heterochromia iridum, one blue eye and one brown eye), a white forelock or patches of light skin. These basic features constitute type 2 of the condition; in type 1, there is also a wider gap between the inner corners of the eyes called telecanthus, telecanthus, or dystopia canthorum. In type 3, which is rare, the arms and hands are also malformed, with Camptodactyly, permanent finger contractures or fused fingers, while in type 4, the person also has Hirschsprung's disease. There also exist at least two types (2E and PCWH) that can result in central nervous system (CNS) symptoms such as developmental delay and muscle tone abnormalities. The syndrome is caused by mutations in any of several genes that affect the Cell division, division and Cell migration, migration of neural crest cells d ...

Tungsten Disulfide
Tungsten disulfide is an inorganic chemical compound composed of tungsten and sulfur with the chemical formula WS2. This compound is part of the group of materials called the transition metal dichalcogenides. It occurs naturally as the rare mineral tungstenite. This material is a component of certain catalysts used for hydrodesulfurization and hydrodenitrification. WS2 adopts a layered structure similar, or isotypic with MoS2, instead with W atoms situated in trigonal prismatic coordination sphere (in place of Mo atoms). Owing to this layered structure, WS2 forms non-carbon nanotubes, which were discovered after heating a thin sample of WS2 in 1992. Structure and physical properties Bulk WS2 forms dark gray hexagonal crystals with a layered structure. Like the closely related MoS2, it exhibits properties of a dry lubricant. Although it has long been thought that WS2 is relatively stable in ambient air, recent reports on the ambient air oxidation of monolayer WS2 have found ...

Torch Of Freed Without
A torch is a stick with combustible material at one end, which is ignited and used as a light source. Torches have been used throughout history, and are still used in processions, symbolic and religious events, and in juggling entertainment. In some countries "torch" in modern usage is the term for a battery-operated portable light. Etymology From the Old French "''torche''" meaning "twisted thing", hence "torch formed of twisted tow dipped in wax", probably from Vulgar Latin *''torca'', alteration of Late Latin ''torqua'', variant of classical Latin ''torques'' "collar of twisted metal", from ''torquere'' "to twist". Torch construction Torch construction has varied through history depending on the torch's purpose. Torches were usually constructed of a wooden stave with one end wrapped in a material which was soaked in a flammable substance. In the United States, black bear bones may have been used. Modern procession torches are made from coarse hessian rolled into a tube a ...

David Weber
David Mark Weber (born October 24, 1952) is an American science fiction and fantasy author. He has written several science-fiction and fantasy books series, the best known of which is the Honorverse, Honor Harrington science-fiction series. His debut novel, first novel, which he worked on with Steve White, sold in 1989 to Baen Books. Baen remains Weber's major publisher. Writing career Born in Cleveland, Ohio on October 24, 1952, Weber began writing while in elementary school, fifth grade. Some of Weber's first jobs within the writing/advertising world began after high school when he worked as copywriter, typesetter, proofreader, and paste-up artist. He later earned an undergraduate degree from Warren Wilson College in Asheville, North Carolina and a Master of Arts, M.A. in history from Appalachian State University in Boone, North Carolina. Weber's first published novels grew out of his work as a wargame designer for the Task Force Games, Task Force board wargame ''Starfire ( ...

WS-2 (MRL)
The Weishi (WS; ) family of multiple rocket launcher systems were mainly developed by Sichuan Aerospace Industry Corporation (SCAIC, also known as Base 062) in Chengdu, China. The systems include the WS-1 (), the improved WS-1B (), the WS-1E (), the WS-2 (), as well as many other models. The WS-1 series weapon system did not enter PLA service and has order from Thailand. The WS-2 may finally see PLA service in the future. It's worth noticing that although sharing the same name, there are other developers for different models of Weishi series multiple rocket launchers (MRL) other than the primary developer SCAIC. China Aerospace Long-March International ALIT (CASC) has published a table showing the ranges of most of the WS rockets. There are unguided, guided and precision guided rockets. WS-1 SCAIC began to develop an unguided large-calibre multiple launch rocket system for the PLA ground forces in the late 1980s. The resulting Weishi-1 (WS-1) 302 mm, 4-tube multiple r ...
