Bark (utterance)
A bark is a sound most commonly produced from dogs. Other animals that make this noise include, but are not limited to, wolves, coyotes, foxes, seals and barking owls. Woof is the most common onomatopoeia in the English language for this sound. "Bark" is also a verb that describes the sound of many canids. University of Massachusetts Amherst researchers define a bark as a short vocalization. Definition While there is not a precise, consistent and functional acoustic definition for barking, researchers may classify barks according to several criteria. University of Massachusetts Amherst researchers define a bark as a short, abrupt vocalization that is relatively loud and high-pitched, changes in frequency and often repeats rapidly in succession.Lord, Kathryn., Feinstein, Mark., Coppinger, RaymondBarking and mobbing. ''Behavioural Processes''. 2009. In dogs Dog barking is distinct from wolf barking. Wolf barks represent only 2.4% of all wolf vocalizations and are describ ...

A Dog Mid-bark
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...

Alaskan Malamute
The Alaskan Malamute () is a large breed of dog that was originally bred for its strength and endurance to haul heavy freight as a sled dog and hound. It is similar to other arctic breeds such as the husky, the spitz, the Greenland Dog, Canadian Eskimo Dog, the Siberian Husky, and the Samoyed. Lineage Although it is believed that the first dogs arrived in the Americas 12,000 years ago, people and their dogs did not settle in the Arctic until the Paleo-Eskimo people 4,500 years ago, followed by the Thule people 1,000 years ago, with both originating from Siberia. Malamutes were thought to be bred by the Malimiut Inupiaq people of Alaska's Norton Sound region. The Malamute has been identified as a basal breed that predates the emergence of the modern breeds in the 19th century. A study in 2013 showed that the Alaskan Malamute has a similar east Asian origin to, but is not clearly related to, the Greenland Dog and the Canadian Eskimo Dog, but contains a possible admixture ...

Operant Conditioning
Operant conditioning, also called instrumental conditioning, is a learning process where behaviors are modified through the association of stimuli with reinforcement or punishment. In it, operants—behaviors that affect one's environment—are conditioned to occur or not occur depending on the environmental consequences of the behavior. Operant conditioning originated in the work of Edward Thorndike, whose law of effect theorised that behaviors arise as a result of whether their consequences are satisfying or discomforting. In the 20th century, operant conditioning was studied by behaviorist psychologists, who believed that much, if not all, of mind and behaviour can be explained as a result of envirionmental conditioning. Reinforcements are environmental stimuli that increase behaviors, whereas punishments are stimuli that decrease behaviors. Both kinds of stimuli can be further categorised into positive and negative stimuli, which respectively involve the addition or removal ...

Clicker Training
Clicker training is a positive reinforcement animal training method based on a bridging stimulus ( the clicker) in operant conditioning. The system uses conditioned reinforcers, which a trainer can deliver more quickly and more precisely than primary reinforcers such as food. The term "clicker" comes from a small metal cricket noisemaker adapted from a child's toy that the trainer uses to precisely mark the desired behavior. When training a new behavior, the clicker helps the animal to quickly identify the precise behavior that results in the treat. The technique is popular with dog trainers, but can be used for all kinds of domestic and wild animals. Sometimes, instead of a click to mark the desired behavior, other distinctive sounds are made (such as a "whistle, a click of the tongue, a snap of the fingers, or even a word") [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citronella Oil
Citronella oil Citronella oil is an essential oil obtained from the leaves and stems of different species of ''Cymbopogon'' (lemongrass). The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol, and geraniol. These chemicals find extensive use in soap, candles and incense, perfumery, cosmetic, and flavouring industries throughout the world. Citronella oil is also a plant-based insect repellent and has been registered for this use in the United States since 1948. The United States Environmental Protection Agency considers oil of citronella as a biopesticide with a non-toxic mode of action. Citronella oil has strong antifungal properties. Types Citronella oil is classified in trade into two chemotypes:Chang, Yu Shyun, 2007, ''8 Map species from Malaysia for ICS,'' Forest Research Institute Malaysia, Workshop on NFP, 28–29 May 2007, Nanchang, PR China Ceylon type * CAS: 89998-15-2 * CAS: 8000-29-1 * EINECS: 289-753-6 * FEMA: 2308 * CoE: ...

Electric Shock
Electrical injury is a physiological reaction caused by electric current passing through the body. The injury depends on the density of the current, tissue resistance and duration of contact. Very small currents may be imperceptible or produce a light tingling sensation. A shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. Stronger currents may cause some degree of discomfort or pain, while more intense currents may induce involuntary muscle contractions, preventing the person from breaking free of the source of electricity. Still larger currents result in tissue damage and may trigger ventricular fibrillation or cardiac arrest. Consequences of injury from electricity may include amputations, bone fractures and orthopedic and musculoskeletal injuries. If death results from an electric shock the cause of death is generally referred to as electrocution. Electric injury occurs upon contact of a body part ...

Shock Collar
A shock collar or remote training collar is any of a family of training collars (also called e-collars, Ecollars, or electronic collars) that deliver electrical stimulation of varying intensity and duration to the neck of a dog (they can also be applied to other places on the dog's body, to achieve various training effects) via a radio-controlled electronic device incorporated into a dog collar. Some collar models also include a tone or vibrational setting, as an alternative to or in conjunction with the shock. Others include integration with Internet mapping capabilities and GPS to locate the dog or alert an owner of his/her whereabouts. Originally used in the late 1960s to train hunting dogs, early collars were very high powered. Many modern versions are capable of delivering very low levels of shock. Shock collars are now readily available and have been used in a range of applications, including behavioral modification, obedience training, and pet containment, as well as mili ...

Animal Behavior
Ethology is the scientific study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait. Behaviourism as a term also describes the scientific and objective study of animal behaviour, usually referring to measured responses to stimuli or to trained behavioural responses in a laboratory context, without a particular emphasis on evolutionary adaptivity. Throughout history, different naturalists have studied aspects of animal behaviour. Ethology has its scientific roots in the work of Charles Darwin and of American and German ornithologists of the late 19th and early 20th century, including Charles O. Whitman, Oskar Heinroth, and Wallace Craig. The modern discipline of ethology is generally considered to have begun during the 1930s with the work of Dutch biologist Nikolaas Tinbergen and Austrian biologists Konrad Lorenz and Karl von Frisch, the three recipients of the 1973 Nobel Prize in Phys ...

Hand Signal
Hand signals are given by cyclists and some motorists to indicate their intentions to other traffic. Under the Vienna Convention on Traffic, bicycles are considered 'vehicles' and cyclists are considered 'drivers', a naming convention reflected in most traffic codes. In some countries such as the Czech Republic,The law of the Czech Republic361/2000 Sb. § 30 Canada, and the United States, hand signals apply not only to cyclists, but also to any vehicle whose signal lights are missing or damaged. This rule also applies to drivers of small motorized vehicles such as mopeds and motorcycles. As in automobiles, cyclists use three primary signals: left turn/overtaking, right turn, and stopping/braking. Left turn In right-hand traffic countries, the left turn hand signal is also used to indicate overtaking to the left. ; All countries : To signal a left turn, the driver horizontally extends their left arm outwards. ; South Africa : The driver extends his/her right arm with th ...

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, craft, science and technology have ...
