High-rise Syndrome
High-rise syndrome is a veterinary term for injuries sustained by a cat falling from a building, typically higher than two stories (). Injuries sustained by cats falling Common injuries sustained in cats after a fall include: * Broken bones, most likely the jawbone as the cat's chin hits the ground; a broken jawbone and damaged or shattered teeth are the typical signs of a cat having sustained injuries in a fall. * Injuries to the legs: joint injury; ruptured tendons; ligament injury; broken legs. * Internal injuries, especially to the lungs Studies done of cats that have fallen from 2 to 32 stories, and are still alive when brought to a veterinarian clinic, show that the overall survival rate is 90 percent of those treated. In a study performed in 1987 it was reported that cats who fall from less than six stories, and are still alive, have greater injuries than cats who fall from higher than six stories. It has been proposed that this might happen because cats reach termina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin Badensche Straße Katze Auf Balkon 03
Berlin is the capital and largest city of Germany, both by area and by population. Its more than 3.85 million inhabitants make it the European Union's most populous city, as measured by population within city limits having gained this status after the United Kingdom's, and thus London's, departure from the European Union. Simultaneously, the city is one of the states of Germany, and is the third smallest state in the country in terms of area. Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby. The urban area of Berlin has a population of over 4.5 million and is therefore the most populous urban area in Germany. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan region after the Rhine-Ruhr region, and the fifth-biggest metropolitan region by GDP in the European Union. Berlin was built along the banks of the Spree river, which flows into the Havel in the western boro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mandibular Fracture
Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone. In about 60% of cases the break occurs in two places. It may result in a decreased ability to fully open the mouth. Often the teeth will not feel properly aligned or there may be bleeding of the gums. Mandibular fractures occur most commonly among males in their 30s. Mandibular fractures are typically the result of trauma. This can include a fall onto the chin or a hit from the side. Rarely they may be due to osteonecrosis or tumors in the bone. The most common area of fracture is at the condyle (36%), body (21%), angle (20%) and symphysis (14%). While a diagnosis can occasionally be made with plain X-ray, modern CT scans are more accurate. Immediate surgery is not necessarily required. Occasionally people may go home and follow up for surgery in the next few days. A number of surgical techniques may be used including maxillomandibular fixation and open reduction internal fixati ...

Tendon Rupture
Tendon rupture is a condition in which a tendon separates in whole or in part from tissue to which it is attached, or is itself torn or otherwise divided in whole or in part. Examples include: * Achilles tendon rupture * Biceps tendon rupture * Anterior cruciate ligament injury * Biceps femoris tendon rupture and Quadriceps tendon rupture * Cruciate ligament#Rupture * Patellar tendon rupture Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. Often there is sudden onset of pain and walking is difficult. In a complete rupture, the ability to extend that knee is decreased. A pop may be felt ... References {{reflist Injuries ...

Founded in autumn 1869, ''Nature'' was first circulated by Norman Lockyer and Alexander Macmillan as a public forum for scientific innovations. The mid-20th century facilitated an editorial expansion for the journal; ''Nature'' redoubled its efforts in exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Straight Dope
"The Straight Dope" was a question-and-answer newspaper column written under the pseudonym Cecil Adams. Contributions were made by multiple authors, and it was illustrated (also pseudonymously) by Slug Signorino. It was first published in 1973 in the ''Chicago Reader'' as well as in print syndication nationally in the United States, and on a website with the same name. On more than one occasion, the authors (i.e. Cecil Adams) were forced to retract or modify an answer when confronted by the readers. Following the column of June 27, 2018, the "Straight Dope" column was placed on hiatus, with no decision made regarding its future. The website and associated forum continue to be active. Chicago's public radio station, WBEZ, has purchased Sun-Times Media (STM), which owns the Straight Dope, including the SDMB. Name and tagline The column derives its name from the American idiom meaning roughly "the true information; the full story" and covers many subjects, including history, scien ...

Terminal Velocity
Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (''Fd'') and the buoyancy is equal to the downward force of gravity (''FG'') acting on the object. Since the net force on the object is zero, the object has zero acceleration. In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving. As the speed of an object increases, so does the drag force acting on it, which also depends on the substance it is passing through (for example air or water). At some speed, the drag or force of resistance will equal the gravitational pull on the object (buoyancy is considered below). At this point the object stops accelerating and continues falling at a constant speed called the terminal velocity (also called settling velocity). An object moving downward faster than ...

Survivorship Bias
Survivorship bias or survival bias is the logical error of concentrating on entities that passed a selection process while overlooking those that did not. This can lead to incorrect conclusions because of incomplete data. Survivorship bias is a form of selection bias that can lead to overly optimistic beliefs because multiple failures are overlooked, such as when companies that no longer exist are excluded from analyses of financial performance. It can also lead to the false belief that the successes in a group have some special property, rather than just coincidence as in correlation "proves" causality. Another kind of survivorship bias would involve thinking that an incident was not all that dangerous because the only people who were involved in the incident who can speak about it are those who survived it. Even if one knew that some people are dead, they would not have their voice to add to the conversation, leading to bias in the conversation. As a general experimental ...

Equilibrioception
The sense of balance or equilibrioception is the perception of balance and spatial orientation. It helps prevent humans and nonhuman animals from falling over when standing or moving. Equilibrioception is the result of a number of sensory systems working together; the eyes (visual system), the inner ears (vestibular system), and the body's sense of where it is in space (proprioception) ideally need to be intact. The vestibular system, the region of the inner ear where three semicircular canals converge, works with the visual system to keep objects in focus when the head is moving. This is called the vestibulo-ocular reflex (VOR). The balance system works with the visual and skeletal systems (the muscles and joints and their sensors) to maintain orientation or balance. Visual signals sent to the brain about the body's position in relation to its surroundings are processed by the brain and compared to information from the vestibular and skeletal systems. Vestibular system In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cat Righting Reflex
The cat righting reflex is a cat's innate ability to orient itself as it falls in order to land on its feet. The righting reflex begins to appear at 3–4 weeks of age, and is perfected at 6–9 weeks. Cats are able to do this because they have an unusually flexible backbone and no functional clavicle (collarbone). The tail seems to help but cats without a tail also have this ability, since a cat mostly turns by moving its legs and twisting its spine in a certain sequence.

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Veterinary Medical Association
The American Veterinary Medical Association (AVMA), founded in 1863, is a not-for-profit association representing more than 99,500 veterinarians in the US. The AVMA provides information resources, continuing education opportunities, publications, and discounts on personal and professional products, programs, and services. The AVMA indicates that it lobbies for animal friendly legislation within a framework that supports the use of animals for human purposes (e.g., food, fiber, research, companionship). The AVMA Council on Education is the designated accrediting body for schools of veterinary medicine in the United States. The AVMA publishes the ''Journal of the American Veterinary Medical Association'' (JAVMA) and the ''American Journal of Veterinary Research'' (AJVR). The AVMA's veterinary student organization is the Student American Veterinary Medical Association (SAVMA).

Cat Behavior
Cat behavior includes body language, elimination habits, aggression, play, communication, hunting, grooming, urine marking, and face rubbing. It varies among individuals, colonies, and breeds. Communication and sociability can vary greatly among individual cats. In a family with many cats, the interactions can change depending on which individuals are present and how restricted the territory and resources are. One or more individuals may become aggressive: fighting may occur with the attack resulting in scratches and deep bite wounds. Communication Kittens vocalize early in development. Some examples of different vocalizations are described below. * Purring - means that the cat is either content or is self-soothing due to fear * Meow - a frequently used greeting. A mother meows when interacting with her young. * Hissing or spitting - indicates an angry or defensive cat. * Yowl - means that the cat is in distress or feeling aggressive. * Chattering - occurs when hunti ...
