Venezuelan Criollo
Venezuelan Criollo or Criollo Limonero, are a landrace breed of Bos taurus that have adapted over the past 400 years to the tropical dry forests of Zulia, Venezuela (and which gain their name from the Limón River, there, and also likely due to their limón color).{{Cite web, url=https://portalmismascotas.com.ar/?accion=razas-det&anim=4&raza=7&descrip=CRIOLLO%20LIMONERO, title=Criollo Limonero, last=, first=, date=, website=Portal mis Mascotas, url-status=live, archive-url=, archive-date=, access-date= Criollo Limonero, like other Criollo cattle bio-types, have descended from Andalusian breeds of cattle brought to the Americas by early explorers to the New World. Criollo Limonero are prized for having good milk yields, high fertility, and a docile temperament. Criollo Limonero are considered national patrimony to Venezuela; some studies show a high genetic diversity among the breed which researchers view as a resource for conserving the sustainable, locally adapted dairy breed. ...

Landrace
A landrace is a domesticated, locally adapted, often traditional variety of a species of animal or plant that has developed over time, through adaptation to its natural and cultural environment of agriculture and pastoralism, and due to isolation from other populations of the species. Landraces are distinct from cultivars and from standard breeds. A significant proportion of farmers around the world grow landrace crops., and most plant landraces are associated with traditional agricultural systems. Landraces of many crops have probably been grown for millennia. Increasing reliance upon modern plant cultivars that are bred to be uniform has led to a reduction in biodiversity, because most of the genetic diversity of domesticated plant species lies in landraces and other traditionally used varieties. Some farmers using scientifically improved varieties also continue to raise landraces for agronomic reasons that include: better adaptation to the local environment, lower fertilizer r ...

Raramuri Criollo
The Rarámuri Criollo is a landrace biotype of Criollo cattle indigenous to the Sierra Tarahumara region of the Copper Canyon, Mexico. In 2005 a small group was introduced to the Jornada Experimental Range (JER) in New Mexico, in the United States for scientific study. History Rarámuri Criollo cattle are descendants of the first cattle brought to Mexico by Hernán Cortés and Villalobos. Until recently, this biotype was geographically isolated between Chínipas and Témoris, Chihuahua in the remote Rio Oteros region of the Copper Canyon, home to the Tarahumara. The Tarahumara, who also call themselves Rarámuri, meaning "fleet foot", have raised this biotype for over 500 years. The Rarámuri typically used the cattle for milk and companionship, wherein animals were often kept indoors adjacent to the house as a source of winter heat. The Rarámuri Criollo experienced little-to-no artificial selection and is suspected to have little-to-no genetic introgression from outsid ...

Zebu
The zebu (; ''Bos indicus'' or ''Bos taurus indicus''), sometimes known in the plural as indicine cattle or humped cattle, is a species or subspecies of domestic cattle originating in the Indian sub-continent. Zebu are characterised by a fatty hump on their shoulders, a large dewlap, and sometimes drooping ears. They are well adapted to withstanding high temperatures, and are farmed throughout the tropical countries, both as pure zebu and as hybrids with taurine cattle, the other main type of domestic cattle. Zebu are used as draught and riding animals, dairy cattle, and beef cattle, as well as for byproducts such as hides and dung for fuel and manure. Some small breeds such as the miniature zebu are also kept as pets. In 1999, researchers at Texas A&M University successfully cloned a zebu. In some regions, such as parts of India, cattle, especially zebu, have significant religious meaning. Taxonomy and name The scientific name ''Bos indicus'' was introduced by Carl Linnae ...

Heat Dissipation
All electronic devices and circuitry generate excess heat and thus require thermal management to improve reliability and prevent premature failure. The amount of heat output is equal to the power input, if there are no other energy interactions. There are several techniques for cooling including various styles of heat sinks, thermoelectric coolers, forced air systems and fans, heat pipes, and others. In cases of extreme low environmental temperatures, it may actually be necessary to heat the electronic components to achieve satisfactory operation. Overview Thermal resistance of devices This is usually quoted as the thermal resistance from junction to case of the semiconductor device. The units are °C/W. For example, a heatsink rated at 10 °C/W will get 10 °C hotter than the surrounding air when it dissipates 1 Watt of heat. Thus, a heatsink with a low °C/W value is more efficient than a heatsink with a high °C/W value. Given two semiconductor device ...

Anatomy And Physiology
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic and microscopic. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch o ...

Bay (horse)
Bay is a hair coat color of horses, characterized by a reddish-brown or brown body color with a black point coloration on the mane, tail, ear edges, and lower legs. Bay is one of the most common coat colors in many horse breeds. The black areas of a bay horse's hair coat are called "black points", and without them, a horse is not a bay horse. Black points may sometimes be covered by white markings; however such markings do not alter a horse's classification as "bay". Bay horses have dark skin – except under white markings, where the skin is pink. Genetically, bay occurs when a horse carries both the Agouti gene and a black base coat. While the basic genetics that create bay coloring are fairly simple, the genes themselves and the mechanisms that cause shade variations within the bay family are quite complex and, at times, disputed. The genetics of dark shades of bay are still under study. The genetic mechanism that produces seal brown has yet to be isolated. Sooty genet ...

Dolichocephalic
Dolichocephaly (derived from the Ancient Greek δολιχός 'long' and κεφαλή 'head') is a condition where the head is longer than would be expected, relative to its width. In humans, scaphocephaly is a form of dolichocephaly. Dolichocephalic dogs (such as German Shepherds) have elongated noses. This makes them vulnerable to fungal diseases of the nose such as aspergillosis. In humans the anterior–posterior diameter (length) of dolichocephaly head is more than the transverse diameter (width). It can be present in cases of Sensenbrenner syndrome, Crouzon syndrome, Sotos syndrome, CMFTD as well as Marfan syndrome. See also * Brachycephaly * Cephalic index * Plagiocephaly Plagiocephaly, also known as flat head syndrome, is a condition characterized by an asymmetrical distortion (flattening of one side) of the skull. A mild and widespread form is characterized by a flat spot on the back or one side of the head cause ... References External links Congenital d ...

American Milking Devon
The American Milking Devon is an American breed of dual-purpose cattle, reared both for milk and for beef. It derives from the Devon cattle of the United States, which in turn are derived from the North Devon cattle of south-west England. It was established as a separate breed in 1978 with the formation of the American Milking Devon Cattle Association, after the breeding aims of the Devon were concentrated almost exclusively on beef production. It is a rare breed: its conservation status is listed as by the Livestock Conservancy as 'critical'. History In 1624, the first cattle – three heifers and a bull – were brought by Edward Winslow from the county of Devon in south-west England to the Plymouth Colony, in what would later be Massachusetts.Fraser, Rebecca. ''The Mayflower: The Families, the Voyage, and the Founding of America,'' pp. 97-8, St. Martin's Press, New York, 2017.

Romosinuano
The Romosinuano is a breed of cattle native to Colombia. Its name derives from the fact that the breed is polled (''romo'') and that it originated from the Sinú River valley (''sinuano''). Romosinunao are a criollo type, developed from the horned '' Costeño con Cuernos'' breed of Spanish origin. It is unclear whether the polled nature of the Romosinuano was due to natural mutation or to cross-breeding with European types such as the Angus or Red Poll. Romosinuano are beef cattle, and are noted for their docile temperament and adaptation to subtropical climates. Romosinuano lines also exist in Costa Rica and Venezuela, and have been imported to the United States for cross-breeding in the hopes of improving cattle production in Florida Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and ...

Corriente
Corriente cattle are a breed of Criollo cattle descended from Spanish animals brought to the Americas as early as 1493. They are primarily used today as sport cattle for rodeo events such as team roping and bulldogging (steer wrestling). Some breeders raise them for their meat, which contains approximately half the fat of the meat from most modern beef cattle. Corrientes are fairly small cattle, with cows averaging well under 1,000 pounds (450 kg). They are lean, athletic, and have long upcurving horns. They are known as "easy keepers," as little human intervention is required in their calving, and they eat significantly less than larger beef cattle breeds. Like other Criollo breeds, the corriente require less water and can live on sparse open range. Corrientes are also known as accomplished escape artists, as they can leap a standard barbed-wire fence and squeeze through fairly small openings. Names for the breed differ.
