Physical deformation

Refractoriness. Most refractories are mixtures of different oxides, sometimes with significant quantities of impurities. Thus, they do not have sharp melting points but a softening range. Refractoriness is the resistance to physical deformation under the influence of temperature. It is determined by the pyrometric cone equivalent (PCE) test for aluminosiHcates and resistance to creep or shear at high temperature (see Analytical methods). [Pg.30]

Evaluate patients for progression of osteoporosis, including signs and symptoms of new fragility fracture (e.g., localized pain), loss of height, and physical deformity (e.g., kyphosis). Patients should be assessed on an annual basis or more often if new symptoms present. [Pg.865]

Toxicologists nowadays take a broad view of developmental toxicity they consider not only structural but also functional abnormalities to qualify as adverse, as long as they were produced as a result of exposures incurred in utero. Thus, for example, the developmental effects of chronic alcohol abuse by pregnant women, known as fetal alcohol syndrome (FAS), are characterized not only by the presence of certain craniofacial abnormalities, but also by a variety of disabilities such as shortened attention span, speech disorders, and restlessness. Although fully expressed physical deformities included in FAS are associated with heavy drinking, debate continues on the level of alcohol consumption, if any, that is without these more subtle effects on behavior. [Pg.132]

Similar to FAS with learning and nervous system disabilities without the obvious physical deformities... [Pg.250]

LBP, stiff shoulder, epicondylitis and tendonitis. In soft tissue rheumatism pain at rest and/or during activity, stiffness, tenderness, and disability are the predominant features. Physical deformities are minimal but disabilities are major problems. [Pg.660]

In section IID, we introduced the utilization of chemical enhancement effect for higher sensitivity in TERS. Here, it should be pointed out that in addition to electromagnetic enhancement and chemical enhancement effects, physical deformation induced by tip-applied force showed extra enhancement effect in TERS on carbon materials such as SWNTs and fullerene molecules (Yano et al. 2005, 2006 Verma et al. 2006). This tip-pressurized effect is a unique feature of TERS and not observable in SERS. Since the spatial resolution of TERS with tip-pressurized effect is determined by the size of the very end of the metallic tip that has direct contact with the molecules, this is a very promising approach to improve the spatial resolution of the near-field microscope. [Pg.250]

Wide range of severity. No corneal clouding, but physical deformity and mental retardation is mild to severe. [Pg.162]

Piezoelectricity was discovered by the Curie brothers in 1880. The term piezo is derived from the Greek word meaning "to press." The effect causes a crystal to exhibit electrical polarity when the crystal is subjected to mechanical pressure. Conversely, ihe crystal is physically deformed when subjected to an electrical potential. Specifically, piezoelectricity is a property of nonconducting solids dial have a crystal lattice that does not have a center of symmetry. [Pg.462]

In animals, THC can cause spontaneous abortion, low birth weight, and physical deformities (32). However, these were only seen after treatment with extremely high doses of THC (50-150 times higher than human doses), and only in rodents and not in monkeys. [Pg.470]

The teratogenic effects, or potential for the medication to cause physical deformity in the infant—the medication must be taken during organogenesis (first 3 months) for this to occur, and delay until after the first 3 months of pregnancy is preferred. [Pg.191]

When this polymer is processed in a particular way, it becomes piezoelectric and pyroelectric. A piezoelectric substance produces an electric current when it is physically deformed or alternatively undergoes a deformation caused by the application of a current. A pyroelectric material is one that develops an electrical potential in response to a change in its temperature. [Pg.1040]

Bone is a living and functioning part of the body. A broken bone will generate new growth to repair the fracture and fill in any areas from which bone is removed. Therefore, a bone that is congenitally deformed (from birth) can be manipulated, cut, braced, or otherwise treated to provide a normal form. A broken bone held in alignment will heal and no physical deformity will result. [Pg.686]

Compression force is the major driving force in the powder densification process. The rate and extent of the applied force on the powder bed not only affects the way panicles physically deform but also determines the integrity of the compact formed (crushing strength/tensile strength). [Pg.491]

FAS consists of gross physical deformities that are identifiable at birth. FAS is associated with continued physical problems as well as below-average intellectual functioning later in childhood. [Pg.239]

Actual dislocation density data for natural minerals are quite limited and are skewed toward physically deformed phases with high numbers of dislocations (Table I). [Pg.468]
