Tsigai
Tsigai is a Romanian sheep breed. History The Țigaie breed is part of the domestic sheep species (Ovis aries). The breed originates from sheep domesticated in the area of the eastern part of the Black Sea and through migration over time, through the north and south of the sea reaching the south of Moldova and the area of Dobrogea, where it began to form as a local breed, being one of the first breeds of sheep from Europe. By some authors it is considered an old race, formed early, not being a primitive race, but still unimproved according to modern breeding science, based on population genetics. From the place of formation in southern Moldavia and Dobrogea, Țigaia also spread to Transylvania by the Mocans who practiced transhumance, being acclimatized in the mountain area of the Curbura Carpathians (Săcele-Covasna, Brețcu, Bran, Teșila, Vrancea, Plăiesi, LipTranshumance Romanian shepherds have dispersed the Șigaie race in Southern Ukraine, Russia, Bulgaria, Slovakia and ...

Romania
Romania ( ; ro, România ) is a country located at the crossroads of Central Europe, Central, Eastern Europe, Eastern, and Southeast Europe, Southeastern Europe. It borders Bulgaria to the south, Ukraine to the north, Hungary to the west, Serbia to the southwest, Moldova to the east, and the Black Sea to the southeast. It has a predominantly Temperate climate, temperate-continental climate, and an area of , with a population of around 19 million. Romania is the List of European countries by area, twelfth-largest country in Europe and the List of European Union member states by population, sixth-most populous member state of the European Union. Its capital and largest city is Bucharest, followed by Iași, Cluj-Napoca, Timișoara, Constanța, Craiova, Brașov, and Galați. The Danube, Europe's second-longest river, rises in Germany's Black Forest and flows in a southeasterly direction for , before emptying into Romania's Danube Delta.

Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Keratin
Keratin () is one of a family of structural fibrous proteins also known as ''scleroproteins''. Alpha-keratin (α-keratin) is a type of keratin found in vertebrates. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. Excessive keratinization participate in fortification of certain tissues such as in horns of cattle and rhinos, and armadillos' osteoderm. The only other biological matter known to approximate the toughness of keratinized tissue is chitin. Keratin comes in two types, the primitive, softer forms found in all vertebrates and harder, derived forms found only amon ...

Domestic Sheep Reproduction
Domestic sheep reproduce sexually much like other mammals, and their reproductive strategy is furthermore very similar to other domestic herd animals. A flock of sheep is generally mated by a single ram, which has either been chosen by a farmer or has established dominance through physical contest with other rams (in feral populations). Most sheep have a breeding season (''tupping'') in the autumn, though some are able to breed year-round. Largely as a result of the influence of humans in sheep breeding, ewes often produce multiple lambs. This increase in the lamb births, both in number and birth weight, may cause problems in delivery and lamb survival, requiring the intervention of shepherds. Sexual behavior Ewes generally reach sexual maturity at six to eight months of age, and rams generally at four to six (ram lambs have occasionally been known to impregnate their mothers at two months). Sheep are seasonally polyoestrus animals. Ewes enter into oestrus cycles about every 17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textile Industry
The textile industry is primarily concerned with the design, production and distribution of yarn, cloth and clothing. The raw material may be natural, or synthetic using products of the chemical industry. Industry process Cotton manufacturing Cotton is the world's most important natural fibre. In the year 2007, the global yield was 25 million tons from 35 million hectares cultivated in more than 50 countries. There are five stages of cotton manufacturing: * Cultivating and Harvesting * Preparatory Processes * Spinning — giving yarn * Weaving — giving fabrics * Finishing — giving textiles Synthetic fibres Artificial fibres can be made by extruding a polymer, through a spinneret (polymers) into a medium where it hardens. Wet spinning (rayon) uses a coagulating medium. In dry spinning (acetate and triacetate), the polymer is contained in a solvent that evaporates in the heated exit chamber. In melt spinning (nylons and polyesters) the extruded polymer is cooled in gas or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Körös-Maros National Park
Körös-Maros National Park is one of the 10 national parks in Hungary (area 501.34 km2), located in Békés county, in the Southern Great Plain. The park was created in 1997 for the protection of birds. Körös-Maros National Park has a number of regions such as Kis-Sárrét swamp, Fáspuszta, Mágor-puszta or Kardoskúti Fehértó. It features a bustard reserve established in 1975. The major towns of the area are Szarvas and Dévaványa. The great flocks of birds that can be seen during the autumn migration season at Lake Fehér near Kardoskút. The lake is used as a resting place and nesting site by tens of thousands of plovers, cranes and wild ducks.

Cheesemaking
Cheesemaking (or caseiculture) is the craft of making cheese. The production of cheese, like many other food preservation processes, allows the nutritional and economic value of a food material, in this case milk, to be preserved in concentrated form. Cheesemaking allows the production of the cheese with diverse flavors and consistencies. History Cheesemaking is documented in Egyptian tomb drawings and in ancient Greek literature. Cheesemaking may have originated from Nomad, nomadic herdsmen who stored milk in vessels made from sheep's and goats' stomachs. Because their stomach linings contains a mix of lactic acid, bacteria as milk contaminants and rennet, the milk would fermentation (food), ferment and coagulation (milk), coagulate.Kats, Sandor Ellix; Pollan, Michael (2015).
