CREDENTIAL
A credential is a piece of any document that details a qualification, competence, or authority issued to an individual by a third party with a relevant or ''de facto'' authority or assumed competence to do so. Examples of credentials include academic diplomas, academic degrees, Professional certification, certifications, security clearances, Identity document, identification documents, badges, passwords, user names, key (lock), keys, power of attorney, powers of attorney, and so on. Sometimes publications, such as scientific papers or books, may be viewed as similar to credentials by some people, especially if the publication was peer reviewed or made in a well-known Academic journal, journal or reputable publisher. Types and documentation of credentials A person holding a credential is usually given documentation or secret knowledge (''e.g.,'' a password or key) as proof of the credential. Sometimes this proof (or a copy of it) is held by a third, trusted party. While in some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoology
Zoology ( , ) is the scientific study of animals. Its studies include the anatomy, structure, embryology, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and used this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel a ...

Culicoides
''Culicoides'' is a genus of biting midges in the family Ceratopogonidae. There are over 1000 species in the genus,Connelly, C. RBiting midges: ''Culicoides'' spp.Featured Creatures, Entomology and Nematology Department, University of Florida IFAS. August 2013 Edition. which is divided into many subgenera. Several species are known to be vectors of various diseases and parasites which can affect animals. The genus has a long fossil record, with earliest known fossils being from Burmese amber, around 99 million years old. Notable taxa The systematics and taxonomy of this genus are confused. A large number of species are of unknown relation to those that have been assigned to subgenera already. Furthermore, many subgenera are sometimes elevated to full genus status, or additional genera (such as '' Paradasyhelea'') are included as subgenera herein. A widely cited, periodically updated, subgeneric classification of species of ''Culicoides'' begins with the warning that the traditi ...

Onchocerca
Onchocerca is a genus of parasitic roundworm. It contains one human parasite – '' Onchocerca volvulus'' – which is responsible for the neglected disease Onchocerciasis, also known as "river blindness" because the infected humans tend to live near rivers where host black flies live. Over 40 million people are infected in Africa, Central America, and South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion o .... , Indiana State University. Accessed 14 February 2008.

Strongyle Worm
''Trichostrongylus tenuis'', also known as the strongyle worm, is a gut nematode found in the United Kingdom, sensitive to Pyrantel pamoate. Larvae have a short migration inside the mucosa of the intestine and return quickly to the digestive tract. This endoparasite causes a condition often called strongylosis or 'grouse disease' and which can be the cause of regular crashes in grouse populations. When the adult worm burrows into the caeca walls it causes a lot of damage and internal bleeding which in itself is harmful to the grouse. The worms ultimately reduce the digestive efficiency thus affecting the condition of the grouse. The eggs of the strongyle worm found in the caecal droppings of red grouse, hatch out into a microscopic larvae stage. Living within the dropping they feed off bacteria and organic matter they develop through two moult In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ec ...

Woolhope Naturalists' Field Club
The Woolhope Naturalists' Field Club (or simply the Woolhope Club) is a society devoted to the natural history, geology, archaeology, and history of Herefordshire, England. Founded in 1851, it has had many notable members and played an important early role in the history of mycology in Britain. Foundation The Woolhope Naturalists' Field Club was founded in 1851 "for the practical study, in all its branches, of the Natural History of Herefordshire and the districts immediately adjacent". The club was and still is based in the city of Hereford, but took its name from the Woolhope Dome, an outcrop of Silurian rocks around the village of Woolhope to the south-east of the city. The club's first field meeting was held in the Woolhope area.Anon. (1856). ''Transactions of the Woolhope Naturalists' Field Club'' 1. The club's ''Transactions'' have been published regularly since 1856, and early issues suggest that the membership took an interest not only in geology, but in fossils, botany, ...

Veterinary Pathology
Veterinary pathologists are veterinarians who specialize in the diagnosis of diseases through the examination of animal tissue and body fluids. Like medical pathology, veterinary pathology is divided into two branches, anatomical pathology and clinical pathology. Other than the diagnosis of disease in food-producing animals, companion animals, zoo animals and wildlife, veterinary pathologists also have an important role in drug discovery and safety as well as scientific research. Veterinary anatomical pathology Anatomical pathology (Commonwealth) or anatomic pathology (U.S.) is concerned with the diagnosis of disease based on the gross examination, microscopic, and molecular examination of organs, tissues, and whole bodies ( necropsy). Veterinary pathology also takes into account the structure and function of the body and how particular cells were injured. The Indian, European, Japanese, and American Colleges of Veterinary Pathologists certify veterinary pathologists t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agriculture
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than .

Parasitology
Parasitology is the study of parasites, their host (biology), hosts, and the relationship between them. As a List of biology disciplines, biological discipline, the scope of parasitology is not determined by the organism or environment in question but by their way of life. This means it forms a synthesis of other disciplines, and draws on techniques from fields such as cell biology, bioinformatics, biochemistry, molecular biology, immunology, genetics, evolution and ecology. Fields The study of these diverse organisms means that the subject is often broken up into simpler, more focused units, which use common techniques, even if they are not studying the same organisms or diseases. Much research in parasitology falls somewhere between two or more of these definitions. In general, the study of prokaryotes falls under the field of bacteriology rather than parasitology. Medical The parasitologist F. E. G. Cox noted that "Humans are hosts to nearly 300 species of parasitic worms a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microbiology
Microbiology () is the branches of science, scientific study of microorganisms, those being of unicellular organism, unicellular (single-celled), multicellular organism, multicellular (consisting of complex cells), or non-cellular life, acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. The organisms that constitute the microbial world are characterized as either prokaryotes or eukaryotes; eukaryote, Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryote, prokaryotic organisms are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Microbiologists traditionally relied on culture, staining, and microscopy for the isolation and identification of microorganisms. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
