Dogtooth (anatomy)
In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, or (in the context of the upper jaw) fangs, eye teeth, vampire teeth, or vampire fangs, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called ''incisiform''. They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two maxillary canines and the two mandibular canines. Details There are generally four canine teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterally to ...

Dogtooth, North Dakota
Dogtooth is a ghost town in Grant County, North Dakota, United States. It was so named because the shape of the nearby buttes resembled the molars of a dog's lower jaw. The town was located in Section 11 of survey township T133 North, Range 85 West.Dogtooth, ND Postal Application 1/29/1900 History Dogtooth was first established in 1876 as a station along the Deadwood - Bismarck Trail. The station closed in 1880 when the was completed, but settlers continued to |
Dogtooth (film)
''Dogtooth'' ( el, Κυνόδοντας; ''Kynodontas'') is a 2009 Greek psychological drama film directed by Yorgos Lanthimos. Written by Lanthimos and Efthymis Filippou, the film is about a husband and wife (Christos Stergioglou and Michelle Valley) who keep their children (Angeliki Papoulia, Mary Tsoni and Christos Passalis) ignorant of the world outside their property well into adulthood. ''Dogtooth'' is Lanthimos's second feature film. It won the Prix Un Certain Regard at the 2009 Cannes Film Festival and was nominated for Best Foreign Language Film at the 83rd Academy Awards. Plot A couple live in a fenced-in compound with their adult son and two adult daughters. The children have no knowledge of the outside world; their parents say they will be ready to leave once they lose a dogtooth, and that one can only leave safely by car. The children entertain themselves with endurance games, such as keeping a finger in hot water. They believe they have a brother on the other sid ...

Dog-tooth
In architecture, a dog-tooth or dogtooth pattern is an ornament found in the mouldings of medieval work of the commencement of the 12th century, which is thought to have been introduced by the Crusaders. The earliest example is found in the hall at Rabbath Ammon in Moab in Jordan (c. 614) built by the Sassanians, where it decorates the arch moulding of the blind arcades and the string courses. The pattern consists of four flower petals forming a square or diamond shape with central elements. The petals have the form of the pointed conical canine tooth, eye tooth or cuspid. In the apse of a church at Murano, near Venice, it is similarly employed. In the 12th and 13th centuries it was further elaborated with carving, losing therefore its primitive form, but constituting a most beautiful decorative feature. In Elgin Cathedral in Scotland, the dogtooth ornament in the archivolt becomes a four-lobed leaf, and in Stone church in Kent, a much more enriched type of flower. The term ha ...

Dogtooth Spar
Dogtooth spar is a speleothem that consists of very large calcite crystals resembling dogs' teeth. They form through mineral precipitation of water-borne calcite. Dogtooth spar crystals are found in caves, open spaces including veins and fractures, and geodes. The crystals are generally centimeters long, but anomalous samples decimeters long exist, notably in Sitting Bull Crystal Caverns. A layer of crystalline calcite can be found underneath the surface of crystal points. The crystals typically consist of acute scalenohedrons, twelve triangular crystal faces that ideally form scalene triangles. However, modification of these faces is common, and some may have many more than three edges. Calcite crystallizes in the rhombohedral system, and the most common scalenohedron form has the Miller index 11 Spar SPAR, originally DESPAR, styled as DE SPAR, is a Dutch multinational that provides branding, supplies and support services for independently owned and operated food retai ...

Dogtooth Tuna
The dogtooth tuna ''Gymnosarda unicolor'', also known as white tuna, is a species of pelagic marine fish which belongs to the family Scombridae. Description The dogtooth tuna can reach a length of in males and a weight of .Collette, B.B. and C.E. Nauen, 1983. FAO Species Catalogue. Vol. 2. Scombrids of the world.

These large tunas have a streamlined shape and a distinctive body coloration: brilliant blue green on the back, silvery on the side, and whitish on the belly, with two white tips on the two back fins close to the caudal peduncle. They always swim with open jaws. The upper jaw of the large mouth reaches the eye. Distribution The dogtooth tuna is widespread throughout the tropical ...

Dog's-tooth Violet
''Erythronium'', the fawn lily, trout lily, dog's-tooth violet or adder's tongue, is a genus of Eurasian and North American plants in the lily family, most closely related to tulips. The name Erythronium derives from Ancient Greek () "red" in Greek, referring to the red flowers of ''E. dens-canis''. Of all the established species, most live in North America; only six species are found in Europe and Asia. Species ''Erythronium'' includes about 20–30 species of hardy spring-flowering perennial plants with long, tooth-like bulbs. Slender stems carry pendent flowers with recurved tepals in shades of cream, yellow, pink and mauve. Species are native to forests and meadows in temperate regions of the Northern Hemisphere. Formerly included Two species names were coined using the name ''Erythronium'' but have since been reclassified to other taxa. * ''Erythronium carolinianum'', now called ''Uvularia perfoliata'' * ''Erythronium hyacinthoides'', now called ''Drimia indica'' ...

Dogtooth Extension
A leading-edge extension (LEX) is a small extension to an aircraft wing surface, forward of the leading edge. The primary reason for adding an extension is to improve the airflow at high angles of attack and low airspeeds, to improve handling and delay the stall. A dog tooth can also improve airflow and reduce drag at higher speeds. Leading-edge slat A leading-edge slat is an aerodynamic surface running spanwise just ahead of the wing leading edge. It creates a leading edge slot between the slat and wing which directs air over the wing surface, helping to maintain smooth airflow at low speeds and high angles of attack. This delays the stall, allowing the aircraft to fly at a higher angle of attack. Slats may be made fixed, or retractable in normal flight to minimize drag. Dogtooth extension A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate a vortex flow field to prevent separated flow from progressing o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dog Clutch
A dog clutch (also known as a positive clutch or dog gears) is a type of clutch that couples two rotating shafts or other rotating components by engagement of interlocking teeth or dogs rather than by friction. The two parts of the clutch are designed such that one will push the other, causing both to rotate at the same speed and will never slip. In engineering, a "dog" is a tool or device used to lock two components in relation to each other. Dog clutches are used where slip is undesirable and/or the clutch is not used to control torque. Without slippage, dog clutches are not affected by wear in the same way that friction clutches are, but result in shock when shafts of different speeds are engaged. For this reason they are best used when sudden starting action is acceptable and the inertia of the system is small. Dog clutches are used inside constant-mesh manual transmissions to lock different gears to the rotating input and output shafts. A synchromesh arrangement ensures s ...
