Bristles
A bristle is a stiff hair or feather (natural or artificial), either on an animal, such as a pig, a plant, or on a tool such as a brush or broom. Synthetic types Synthetic materials such as nylon are also used to make bristles in items such as brooms and sweepers. Bristles are often used to make brushes for cleaning purposes, as they are strongly abrasive; common examples include the toothbrush and toilet brush. The bristle brush and the scrub brush are common household cleaning tools, often used to remove dirt or grease from pots and pans. Bristles are also used on brushes other than for cleaning, notably paintbrushes. Bristles are distinguished as ''flagged'' (split, bushy ends) or ''unflagged;'' these are also known as ''flocked'' or ''unflocked'' bristles. In cleaning applications, flagged bristles are suited for dry cleaning (due to picking up dust better than unflagged), and unflagged suited for wet cleaning (due to flagged ends becoming dirty and matted when wet).

Paintbrush
A paintbrush is a brush used to apply paint or ink. A paintbrush is usually made by clamping bristles to a handle with a ferrule. They are available in various sizes, shapes, and materials. Thicker ones are used for filling in, and thinner ones are used for details. They may be subdivided into decorators' brushes used for painting and decorating and artists' brushes use for visual art. History Paintbrushes were used by man as early as the Paleolithic era in around 2.5 million years ago in order to apply pigment. Ancient Egyptian paintbrushes were made of split palm leaves and used by ancestors to beautify their surroundings. The oldest brushes ever found were also made of animal hair.

Bristle Sensilla
Bristle sensilla (sometimes also called tactile hairs) are a class of mechanoreceptors found in insects and other arthropods that respond to mechanical stimuli generated by the external world. As a result, they are considered exteroceptors. Bristle sensilla can be divided into two main types, macrochaete and microchaete, based on their size and physiology. The larger macrochaete are thicker and stouter than the smaller microchaete. Macrochaete are also more consistent in their number and distribution across individuals of the same species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s .... Between species, the organization of macrochaete is more conserved among closely related species, whereas the organization of microchaete is more variable and less correlated with phylogenetic ...

Feather
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. Plumology (or plumage science) is the name for the science that is associated with the study of feathers. Feathers have a number of utilitarian, cultural, and religious uses. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter cloth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toothbrush
A toothbrush is an oral hygiene tool used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth. They should be used in conjunction with something to clean between the teeth where the bristles of the toothbrush cannot reach - for example floss, tape or interdental brushes. They are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard-bristled toothbrushes can damage tooth enamel and irritate the gums. Because many common and effective ingredients in toothpaste are harmful if swallowed in large doses and instead should be spat out, the act of brushing teeth is most often done at a sink within the kitchen or bathroom, where the brush may be rinsed off afterwards to remove any debris remaining and then dried to reduce conditions ideal for germ growth (a ...

Sunburn
Sunburn is a form of radiation burn that affects living tissue, such as skin, that results from an overexposure to ultraviolet (UV) radiation, usually from the Sun. Common symptoms in humans and animals include: red or reddish skin that is hot to the touch or painful, general fatigue, and mild dizziness. Other symptoms include blistering, peeling skin, swelling, itching, and nausea. Excessive UV radiation is the leading cause of (primarily) non-malignant skin tumors,World Health Organization, International Agency for Research on Cance"Do sunscreens prevent skin cancer" Press release No. 132, 5 June 2000World Health Organization, International Agency for Research on Cance"Solar and ultraviolet radiation"IARC Monographs on the Evaluation of Carcinogenic Risks to Humans, Volume 55, November 1997 and in extreme cases can be life-threatening.

Trinity Bristle Snail
The Trinity bristle snail (''Monadenia setosa'') is a species of medium-sized land snail, a terrestrial pulmonate gastropod mollusc in the family Monadeniidae. Description The Trinity bristle snail attains a body length of approximately 2.5 cm. It is brown or chestnut-colored and covered with minuscule, translucent bristles, which give the species its common name. Distribution and habitat This species is endemic to California. This snail is found in northwestern Trinity County, along the Trinity River, up some of its tributaries and into the Corral Bottom area. It has a healthy population within its territory. It likes cool, wet, shady riparian zones, and prefers areas with a deciduous understory. Ecology The Trinity bristle snail is dependent on cool, moist conditions, and therefore it is only active at night. It spends warmer parts of the day stuck to shady areas on tree trunks, and in especially warm parts of the summer it may not move for days. When conditions are ...

Bristle-spined Porcupine
The bristle-spined rat (''Chaetomys subspinosus'') is an arboreal rodent from the Atlantic forest in eastern Brazil. Also known as the bristle-spined porcupine or thin-spined porcupine, it is the only member of the genus ''Chaetomys'' and the subfamily Chaetomyinae. It was officially described in 1818, but rarely sighted since, until December 1986, when two specimens - one a pregnant female - were found in the vicinity of Valencia in Bahia. Since then it has been recorded at several localities in eastern Brazil, from Sergipe to Espírito Santo (there are no recent records from Rio de Janeiro), but it remains rare and threatened due to habitat loss, poaching and roadkills. Characteristics Bristle-spined rats are named because the spines on the back are more bristle-like in texture than the spines on the rest of the body. They have long, naked tails which are not prehensile. Adult animals weigh around . Their skulls are unusual in several ways. The eye socket is almost comp ...

Bristle-thighed Curlew
The bristle-thighed curlew (''Numenius tahitiensis'') is a medium-sized shorebird that breeds in Alaska and winters on tropical Pacific islands. It is known in Mangareva as ''kivi'' or ''kivikivi'' and in Rakahanga as ''kihi''; it is said to be the origin of the name for the New Zealand flightless bird kiwi although some linguists like Robert Blust has proposed an alternate origin from Proto-Oceanic *''kiwiwi'', the Pacific golden plover, instead. Taxonomy The bristle-thighed curlew was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's '' Systema Naturae''. He placed it in the genus '' Scolopax'' and coined the binomial name ''Scolopax tahitiensis''. Gmelin based his description on the "Otaheite curlew" that had been described in 1785 by the English ornithologist John Latham in his ''A General Synopsis of Birds''. "Otaheite" is a former name of Tahiti. The specimen used by Latham was supplied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristlebird
The bristlebirds are a family of passerine birds, Dasyornithidae. There are three species in one genus, ''Dasyornis''. The family is endemic to the south-east coast and south-west corner of Australia.Del Hoyo, J.; Elliot, A. & Christie D. (editors). (2006). ''Handbook of the Birds of the World. Volume 12: Picathartes to Tits and Chickadees''. Lynx Edicions. The genus ''Dasyornis'' was sometimes placed in the Acanthizidae or, as a subfamily, Dasyornithinae, along with the Acanthizinae and Pardalotinae, within an expanded Pardalotidae, before being elevated to full family level by Christidis & Boles (2008).Higgins, P.J.; & Peter, J.M.

Tamworth Pig
The Tamworth, also known as Sandy Back and Tam, is a breed of domestic pig originating in its namesake Tamworth, Staffordshire, United Kingdom. It is among the oldest of pig breeds, but as with many older breeds of livestock, it is not well suited to modern production methods and is listed as "threatened" in the United States and "vulnerable" in the UK by the Rare Breeds Survival Trust, as fewer than 300 registered breeding females remain. This animal is of ginger to red colouration and is thought to have descended from wild boars, via native pig stock of Europe. Principal populations today are in the United Kingdom, Australia, the United States, New Zealand, and Canada. Description This breed exhibits an elongated head shape and a long, narrow body. The ears are erect and pointed, while the face has rectilinear lines as well as the snout. Colours range from a pale gingery to dark mahogany red. Early in the breed history, colours were orange and purple, but breeding has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
