Vinkensport
''Vinkensport'' (Dutch for ''"finch sport"'') is a competitive animal sport in which male common chaffinches are made to compete for the highest number of bird calls in an hour. Also called ''vinkenzetting'' ("finch sitting"). It is primarily active in Flanders, the Dutch-speaking region of Belgium. Vinkensport traces its origins to competitions held by Flemish merchants in 1596, and is considered part of traditional Flemish culture. As of 2007, it was estimated that there are over 13,000 enthusiasts, called ''vinkeniers'' ("finchers"), breeding 10,000 birds every year. Animal rights activists oppose the sport. Description In a contest, a row of small cages, each housing a single male finch, is lined up approximately six feet apart along a street. The proximity of the cages increases the number of calls, as the birds sing for mates and to establish territory. A timekeeper begins and ends the contest with a red flag. Every time a bird sings a correct terminating flourish to thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Hardy
Thomas Hardy (2 June 1840 – 11 January 1928) was an English novelist and poet. A Victorian realist in the tradition of George Eliot, he was influenced both in his novels and in his poetry by Romanticism, including the poetry of William Wordsworth. He was highly critical of much in Victorian society, especially on the declining status of rural people in Britain, such as those from his native South West England. While Hardy wrote poetry throughout his life and regarded himself primarily as a poet, his first collection was not published until 1898. Initially, he gained fame as the author of novels such as '' Far from the Madding Crowd'' (1874), ''The Mayor of Casterbridge'' (1886), '' Tess of the d'Urbervilles'' (1891), and ''Jude the Obscure'' (1895). During his lifetime, Hardy's poetry was acclaimed by younger poets (particularly the Georgians) who viewed him as a mentor. After his death his poems were lauded by Ezra Pound, W. H. Auden and Philip Larkin. Many of his novels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Calls
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the "winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the repetitive and transformative patte ...

Selective Breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vivisection
Vivisection () is surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure. The word is, more broadly, used as a pejorative catch-all term for experimentation on live animalsTansey, E.MReview of ''Vivisection in Historical Perspective by Nicholaas A. Rupke, book reviews, National Center for Biotechnology Information, p. 226. by organizations opposed to animal experimentation,Yarri, Donna''The Ethics of Animal Experimentation: A Critical Analysis and Constructive Christian Proposal, Oxford University Press, 2005, p. 163. but the term is rarely used by practising scientists. Human vivisection, such as live organ harvesting, has been perpetrated as a form of torture. Animal vivisection Research requiring vivisection techniques that cannot be met through other means is often subject to an external ethics review in conception and implementation, and in many jurisdictions use of anesthesia is ...

Blindness
Visual impairment, also known as vision impairment, is a medical definition primarily measured based on an individual's better eye visual acuity; in the absence of treatment such as correctable eyewear, assistive devices, and medical treatment– visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. Low vision is a functional definition of visual impairment that is chronic, uncorrectable with treatment or correctable lenses, and impacts daily living. As such low vision can be used as a disability metric and varies based on an individual's experience, environmental demands, accommodations, and access to services. The American Academy of Ophthalmology defines visual impairment as the best-corrected visual acuity of less than 20/40 in the better eye, and the World Health Organization defines it as a presenting acuity of less than 6/12 in the better eye. The term blindness is used for complete or nearly complete vision loss. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD Player
A CD player is an electronic device that plays audio compact discs, which are a digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music or audiobooks. CD players may be part of home stereo systems, car audio systems, personal computers, or portable CD players such as CD boomboxes. Most CD players produce an output signal via a headphone jack or RCA jacks. To use a CD player in a home stereo system, the user connects an RCA cable from the RCA jacks to a hi-fi (or other amplifier) and loudspeakers for listening to music. To listen to music using a CD player with a headphone output jack, the user plugs headphones or earphones into the headphone jack. Modern units can play audio formats other than the original CD PCM audio coding, such as MP3, AAC and WMA. DJs playing dance music at clubs often use specialized players with an adjustable playback speed to alter the pitch and t ...

Testosterone
Testosterone is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of Male reproductive system, male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of androgenic hair, body hair. In addition, testosterone in both sexes is involved in health and well-being, including moods, behaviour, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss. Testosterone is a steroid from the androstane class containing a ketone and a hydroxyl group at positions three and seventeen respectively. It is Biosynthesis, biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites. It exerts its action through binding to and activation of the androgen receptor. In humans and most other vertebrates, testost ...

Doping (sport)
In competitive sports, doping is the use of banned athletic performance-enhancing drugs by athletic competitors as a way of cheating in sports. The term ''doping'' is widely used by organizations that regulate sporting competitions. The use of drugs to enhance performance is considered unethical, and therefore prohibited, by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbate the ethical violation with overt deception and cheating. The origins of doping in sports go back to the very creation of sport itself. From ancient usage of substances in chariot racing to more recent controversies in doping in baseball, doping in tennis, doping at the Olympic Games, and doping at the Tour de France, popular views among athletes have varied widely from country to country over the years. The general trend among authorities and sporting organizations over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectrogram
A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called ''waterfall displays''. Spectrograms are used extensively in the fields of music, linguistics, sonar, radar, speech processing, seismology, and others. Spectrograms of audio can be used to identify spoken words phonetically, and to analyse the various calls of animals. A spectrogram can be generated by an optical spectrometer, a bank of band-pass filters, by Fourier transform or by a wavelet transform (in which case it is also known as a scaleogram or scalogram). A spectrogram is usually depicted as a heat map, i.e., as an image with the intensity shown by varying the colour or brightness.

Wallonia
Wallonia (; french: Wallonie ), or ; nl, Wallonië ; wa, Waloneye or officially the Walloon Region (french: link=no, Région wallonne),; nl, link=no, Waals gewest; wa, link=no, Redjon walone is one of the three regions of Belgium—along with Flanders and Brussels. Covering the southern portion of the country, Wallonia is primarily French-speaking. It accounts for 55% of Belgium's territory, but only a third of its population. The Walloon Region and the French Community of Belgium, which is the political entity responsible for matters related mainly to culture and education, are independent concepts, because the French Community of Belgium encompasses both Wallonia and the bilingual Brussels-Capital Region. There is a German-speaking minority in eastern Wallonia, resulting from the annexation of three cantons previously part of the German Empire at the conclusion of World War I. This community represents less than 1% of the Belgian population. It forms the German-speak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
