Axial tilt is an astronomical term regarding the inclination angle of a planet's rotational axis in relation to its orbital plane. It is also called axial inclination or obliquity. The axial tilt is expressed as the angle made by one half of the planet's axis and one half of a line drawn through the planet's center and perpendicular to the orbital plane, such that its rotation is in the same rotary direction relative to the former ...

Intraparenchymal hemorrhage, or intracerebral hemorrhage, another type of intra-axial bleeding, can be caused by brain trauma, or it can occur spontaneously in hemorrhagic stroke. As with other types of hemorrhages within the skull, intraparenchymal bleeds are a serious medical emergency because they can increase intracranial pressure. The mortality rate for intraparenchymal bleeds is over 40% (Sanders and McKenna, 2001). More common in adults than in children, intraparenchymal bleeds are usually due to penetrating trauma, but can als ...

Intraventricular hemorrhage (or "IVH") is a bleeding of the ventricles, where the cerebrospinal fluid is normally located. It is particularly common in infants, especially premature infants or those of very low birth weight (Annibale and Hill, 2003). Most intraventricular hemorrhages occur in the first 72 hours after birth (Annibale and Hill, 2003). Intraventricular hemorrhage is rare in adults (Mayfrank et al., 1997) and requires a great deal of force to cause. Thus the hemorrhage usually does not occur without an extensive as ...

The ratio of the length of a column to the least radius of gyration of its cross section is called the slenderness ratio (usually expressed with the Greek letter lambda - λ). This ratio affords a means of classifying columns. All the following are approximate values used for convenience. A short steel column is one whose slenderness ratio does not exceed 50; an intermediate length steel column has a slenderness ratio ranging from 50 to 200, while long steel columns may be assumed as one having a slenderness ratio greater ...

The clavicle serves several functions: It serves as a rigid support from which the scapula and free limb are suspended. This arrangement keeps the upper limb away from the thorax so that the arm has maxiumum range of movement. Covers the cervicoaxillary canal (passageway between the neck and arm), through which several important structures pass. Transmits impacts from the upper limb to the axial skeleton. Even though it is classified as a long bone, the clavicle has no medullary (bone marrow) cavity like other long bones. It is made up of spongy (cancello ...

Ankylosing spondylitis (AS) is a chronic, progressive inflammatory arthritis primarily affecting spine and sacroiliac joints, causing eventual fusion of the spine; it is a member of the group of the spondylarthropathies. Complete fusion results in a complete rigidity of the spine, a condition known as bamboo spine. Treatment is with physiotherapy and medication. Some cases remain mild, while other result in marked disability. Ankylosing spondylitis - Signs and symptoms. The typical patient is ...

See also: Geology The Earth consists of several atmospheric, hydrologic, and mainly geologic layers. Its components are the atmosphere, the hydrosphere, the crust, the mantle, and its core. The biosphere is a tiny layer in this composition and is usually not considered part of the physical layers of the Earth. The geologic component layers of the Earth are located at the following depths below surface: 0 to 60 km - Lithosphere (locally varies between 5 and 200 km) 0 to 35 km - Crust (locally varies between ...

On March 26, 2005, Bob and Mary Schindler announced that their legal options had been exhausted. The next day, Schiavo was given the Anointing of the Sick ("Last Rites"). In accordance with the Catholic ritual of Viaticum, she received the Eucharist for the last time; it had been administered to her once through her feeding tube just before it was removed. The Eucharist, according to the teaching of the Catholic Church, can be received under the consecrated species of bread (referred to as the host) or wine. As her tongue was too dry to receive a small piece of the host, she received under the species o ...

Recent breakthroughs in non-invasive brain imaging have been somewhat limited because most of them have not been completely novel; rather, they are simply refining existing brain imaging techniques. FMRI is a perfect example of this from the early 1990s, and it still remains the most accurate brain imaging technique available today. Advances have been made in a number of ways regarding neuroimaging, and this section will cover some of the more prominent improvements including computational advances, tr ...

In neuroscience, a neural network is a bit of conceptual juggernaut: the conceptual transition from neuroanatomy, a rigorously descriptive discipline of observed structure, to the designation of the parameters delimiting a 'network' can be problematic. In outline a neural network describes a population of physically interconnected neurons or a group of disparate neurons whose inputs or signalling targets define a recognizable circuit. Communication between neurons often involves an electrochemical process. The interface through which ...

Zinc chloride (ZnCl2) is a colorless or white compound of zinc and chlorine that is extremely hygroscopic. Four crystalline structures have been reported, although in pure form (i.e. water-free) only the delta (hexagonal close-packed) phase can form. It can be quenched from the melt to form a glassy material. Concentrated aqueous solutions of zinc chloride have the interesting property of dissolving starch, silk and cellulose, so that solution ...

A bearing is a component used to reduce friction in a machine. Bearings may be classified broadly according to the motions they allow and according to their principle of operation. Bearing mechanical - Major types. Common motions include linear/axial and rotary/radial. A linear or thrust bearing allows motion along a straight line, for example a drawer being pulled out and pushed in. A rotary bearing allows motion about a center, such as a wheel on a shaft or a shaft through a housing. Common kinds of rotar ...

Babbitt metal, also called white metal, is an alloy used to provide the bearing surface in a plain bearing. It was invented in 1839 by Isaac Babbitt in Taunton, Massachusetts, USA. The term is used today to describe a series of alloys used as a bearing metal. Babbit metal is characterized by its resistance to gall. Common compositions for Babbitt alloys: 90% tin 10% copper 89% tin 7% antimony 4% copper 80% lead 15% antimony 5% tin Originally used as a cast in place bulk bearing material, it is now more commonly used as a thi ...

A ball bearing is a common type of rolling-element bearing, a kind of bearing. The term ball bearing sometimes means a bearing assembly which uses spherical bearings as the rolling elements. It also means an individual ball for a bearing assembly. The remainder of this entry uses the term ball for the individual component and ball bearing or just 'bearing' for the assembly. Ball bearings typically support both axial and radial loads and can tolerate some misalignment of the inner and outer races. Also, ball ...
