picture info	Tufted Grass Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat w ...

picture info	Fascicle (botany) In botany, a fascicle is a bundle of leaves or flowers growing crowded together; alternatively the term might refer to the vascular tissues that supply such an organ with nutrients.Shashtri, Varun. Dictionary of Botany. Publisher: Isha Books 2005. However, vascular tissues may occur in fascicles even when the organs they supply are not fascicled. Etymology of fascicle and related terms The term ''fascicle'' and its derived terms such as ''fasciculation'' are from the Latin ''fasciculus'', the diminutive of ''fascis'', a bundle. Accordingly, such words occur in many forms and contexts wherever they are convenient for descriptive purposes. A fascicle may be leaves or flowers on a short shoot where the nodes of a shoot are crowded without clear internodes, such as in species of ''Pinus'' or '' Rhigozum''. However, bundled fibres, nerves or bristles as in tissues or the glochid fascicles of '' Opuntia'' may have little or nothing to do with branch morphology. In pines Leaf fascicle ...

picture info	Pectoral Tuft The following is a glossary of common English language terms used in the description of birds—warm-blooded vertebrates of the class Aves and the only living dinosaurs, characterized by , the ability to in all but the approximately 60 extant species of flightless birds, toothless, , the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart and a strong yet lightweight skeleton. Among other details such as size, proportions and shape, terms defining bird features developed and are used to describe features unique to the class—especially evolutionary adaptations that developed to aid flight. There are, for example, numerous terms describing the complex structural makeup of feathers (e.g., , and ); types of feathers (e.g., , and feathers); and their growth and loss (e.g., , and ). There are thousands of terms that are unique to the study of birds. This glossary makes no attempt to cover them all, concentrating on terms that might be found across ...

	Ungual Tuft In mammals, ungual tufts are tufts of hairs at the base of claws of the forefeet and hindfeet. Their presence has been used as a character in cladistic studies of the Cricetidae, a large family of rodents.Weksler, 2006, p. 19 Rice rats Members of the tribe Oryzomyini ("rice rats"), in the Cricetidae subfamily Sigmodontinae, normally have ungual tufts, but they may be reduced or absent in semiaquatic species (i.e. those adapted to life in the water).Weksler, 2006, p. 81 ''Lundomys molitor'', '' Nectomys apicalis'', the marsh rice rat (''Oryzomys palustris''), and species of ''Holochilus'' lack ungual tufts on their forefeet.Weksler, 2006, p. 23 On the hindfeet, most species have well-developed ungual tufts only on the second to fifth toes, but '' Sooretamys angouya'' and '' Eremoryzomys polius'' also have thick tufts on the first toe.

picture info	Toe Tuft The anatomy of the domestic cat is similar to that of other members of the genus ''Felis''. Mouth Permanent dentition teeth Cats are carnivores that have highly specialized teeth. There are four types of permanent dentition teeth that structure the mouth: twelve ''incisors, four canines, ten premolars and four molars.'' The premolar and first molar are located on each side of the mouth that together are called the carnassial pair. The carnassial pair specialize in cutting food and are parallel to the jaw. The incisors located in the front section of the lower and upper mouth are small, narrow, and have a single root. They are used for grasping and biting food. Deciduous dentition teeth A cat also has a deciduous dentition prior to the formation of the permanent one. This dentition emerges seven days after birth and it is composed of 26 teeth with slight differences. The mouth will have smaller incisors, slender and strongly curved upper canines, vertical lower canines, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Ear Tuft Ear tufts are a collection of fur or feathers found on animals which can resemble an animal's ear or is near the animal's ear. Cats Ear tufts are not found on all cat breeds. The ear tufts are located on the tips of cat ears and are also known as lynx tipping. Cat ear tufts are often confused with cat ear furnishings which is the fur that comes out of the opening of the ear. Cat ear tufts assist with keeping debris out of the ear and guides sound into the ear canal. Birds Bird ear tufts are skin projections covered in feathers found in some bird species, most notably various species of owl, vaguely resembling mammalian ears, but unrelated to the animal's hearing. Theories about their function range from improved ability to camouflage, aiding in finding a suitable mate, to giving a more threatening appearance to discourage predators. In Araucana chicken In the Araucana chicken breed, ear tufts are a mutation. It causes a skin projection covered in feathers to appear on the sid ...

	Enamel Tufts Enamel tufts are hypomineralized ribbon-like structures that run longitudinally to the tooth axis and extend from the dentinoenamel junction (DEJ) one fifth to a third into the enamel. They are called ‘‘tufts’’ due to their wavy look within the enamel microstructure. Biomechanically, enamel tufts are ‘‘closed cracks’’ or defects which, in their manner of propagating, act to prevent enamel fractures. This aspect of them is being studied to see how to make more fracture-resistant materials. However, they can also form without stress during enamel development. Enamel tufts are most common in the enamel of molars of animals that crush hard food objects, such as nuts (crushed by apes) and shellfish (crushed by sea otters). Microstructure Each tuft consists of several unconnected leaves that start near the dentinoenamel junction. These defects as they pass through the enamel rods to the surface become progressively more fragmented and fibrillar. Scanning electron ...

	Tuft Cell Tuft cells are chemosensory cells in the epithelial lining of the intestines. Similar tufted cells are found in the respiratory epithelium where they are known as brush cells. The name "tuft" refers to the brush-like microvilli projecting from the cells. Ordinarily there are very few tuft cells present but they have been shown to greatly increase at times of a parasitic infection. Several studies have proposed a role for tuft cells in defense against parasitic infection. In the intestine, tuft cells are the sole source of secreted interleukin 25 (IL-25). ATOH1 is required for tuft cell specification but not for maintenance of a mature differentiated state, and knockdown of Notch results in increased numbers of tuft cells. Human tuft cells The human gastrointestinal (GI) tract is full of tuft cells for its entire length. These cells were located between the crypts and villi. On the basal pole of all cells was expressed DCLK1. They did not have the same morphology as was descri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Tufting Tufting is a type of textile manufacturing in which a thread is inserted on a primary base. It is an ancient technique for making warm garments, especially mittens. After the knitting is done, short U-shaped loops of extra yarn are introduced through the fabric from the outside so that their ends point inwards (e.g., towards the hand inside the mitten). Usually, the tuft yarns form a regular array of "dots" on the outside, sometimes in a contrasting color (e.g., white on red). On the inside, the tuft yarns may be tied for security, although they need not be. The ends of the tuft yarns are then frayed, so that they will subsequently felt, creating a dense, insulating layer within the knitted garment. Tufting was first developed by carpet manufacturers in Dalton, Georgia. A tufted piece is completed in three steps: tufting, gluing, then backing and finishing. When tufting, the work is completed from the backside of the finished piece. A loop-pile machine sends yarn through the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Tuft (aeronautics) In aeronautics, tufts are strips of yarn or string, typically around , attached to an aircraft surface in a grid pattern and imaged during flight. The motion of the tufts during flight can be observed and recorded, to locate flow features such as boundary layer separation and reattachment. Tufting is, therefore, a technique for flow visualization. They are used in aeronautics flight testing to study air flow direction, strength, and boundary layer properties. The world's largest bed of tufts (18.6 m by 18.6 m, 61 feet by 61 feet) was created at NASA Ames Research Center to study air flow fields involving a helicopter's rotor disk.

picture info	Tassel A tassel is a finishing feature in fabric and clothing decoration. It is a universal ornament that is seen in varying versions in many cultures around the globe. History and use In the Hebrew Bible, the Lord spoke to Moses instructing him to tell the Israelites to make tassels (Hebrew tzitzit) on the corners of their garments, to help them to remember all the commandments of the Lord and to keep them (Numbers 15:37-40), and as a sign of holiness. The religious Hebrew tassel, however, bears little resemblance to the decorative one which appeared and eventually became popular in Europe, especially France and Spain. In the West, tassels were originally a series of windings of thread or string around a suspending string until the desired curvature was attained. Later, turned wooden moulds, which were either covered in simple wrappings or much more elaborate coverings called ''satinings'', were used. This involved an intricate binding of bands of filament silk vertically around the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
