Surrounding depressions

The AFM image and the accompanying vertical displacement profiles reflect both the pores and the surrounding depressions in the membrane surface layer. In contrast, the SEM photomicrograph renders only the defects (pores) with minimal information on the surrounding surface depression due to the two-dimensional character of the image. [Pg.119]

The features created by crustal movements may be mountain chains, like the Himalayas, where collision of continents causes extensive compression. Conversely, the depressions of the Red Sea and East African Rift Basin are formed by extensional plate movements. Both type of movements form large scale depressions into which sediments from the surrounding elevated areas ( highs ) are transported. These depressions are termed sedimentary basins (Fig. 2.3). The basin fill can attain a thickness of several kilometres. [Pg.10]

Rolling oil tanks were corroded on surfaces contacting the emulsion. Small pitlike depressions were present beneath aluminum soap deposits. Each pit was surrounded by a lightly etched region exactly mirroring deposit patterns (Fig. 6.26). [Pg.156]

Figure 11.26 shows a component removed from an air-conditioning compressor. Pinhole perforations in this component had allowed cooling water to leak into the freon. Many failures of this type had occurred previously. Examinations of the internal surfaces of both the canister and the tubes entering it revealed evidence of metal loss. Tiny perforations at the bases of deep grooves were noted in the tubes. Deep, general, smooth metal loss surrounded irregular islands of intact surface (Fig. 11.27). The canister walls displayed a similar metal loss and comet-tail-shaped depressions (Fig. 11.2). Figure 11.26 shows a component removed from an air-conditioning compressor.

The temperature of air as indicated by a thermometer when a water-wet wick encloses its bulb. If the surrounding air is not saturated water will evaporate, taking the latent necessary latent heat from the thermometer bulb which then gives a lower reading than a dry bulb in the same air. The depression in wet bulb temperature is proportional to the amount of moisture in the air. [Pg.437]

Stevens-Johnson syndrome fever, cough, muscular aches and pains, headache, and lesions of the skin, mucous membranes, and eyes. The lesions appear as red wheals or blisters, often starting on die face, in the mo util, or on the lips, neck, and extremities, stomatitis inflammation of die mo util striae lines or bands elevated above or depressed below surrounding tissue, or differing in color or texture subjective data information supplied by the patient or family sublingual under die tongue... [Pg.655]

Perihilar The area surrounding the depression in the medial surface of a lung that forms the opening through which the bronchus, blood vessels, and nerves pass. [Pg.1573]

Figure4.4 c(2 x 2)A structure. Left panel structural model. Right top panel corresponding simulated STM image (VB = + 1.30V, / = 0.04nA). The protrusions correspond to oxygen couples, whereas the depressions are the hollow sites surrounded by O—H complexes. Right bottom panel simulated current profiles along [00 1] at decreasing (light blue to red) tip-surface distances. (Reprinted with permission from Ref. [18].)... Figure4.4 c(2 x 2)A structure.

Neurons are very sensitive to changes in the pH of the interstitial fluid surrounding them. Normally, the pH of arterial blood is 7.4. Under conditions of alkalosis, in which pH increases, the excitability of neurons also increases, rendering them more likely to generate action potentials. This inappropriate stimulation of the nervous system may lead to seizures, particularly in epileptics predisposed to them. Under conditions of acidosis, in which pH decreases, the excitability of neurons is depressed, rendering them less likely to generate action potentials. This lack of nervous system stimulation may lead to a comatose state. Severe diabetic acidosis or acidosis associated with end-stage renal failure will often lead to coma. [Pg.41]

The topography of the Ebro River basin determines a Mediterranean climate with continental characteristics in most of the river basin as well as a semi-arid climate in the center of the depression. At the western extreme of the basin (Pyrenees and Iberian mountains), there is an oceanic climate. The central part of the basin is isolated from the oceanic influence because of the surrounding mountains. This results in the increase of the continentality of the climate and the drastic decrease of the rainfall. In the central part of the river basin (Zaragoza, Alcaniz, and Lleida urban areas), aridity is the main climatic characteristic. [Pg.6]

In this chapter we reviewed taxometric studies in domains of psychopathology that only recently attracted the attention of taxometricians eating disorders, depression, anxiety, personality disorder, and issues surrounding comorbidity. In all these areas the findings are mixed, and it is impossible to offer a verdict about the taxonic status of any of these forms of psychopathol-... [Pg.173]

Macula, plural maculae 1) A small spot, perceptibly different in color from the surrounding tissue. 2) A small, discolored patch or spot on the skin, neither elevated above nor depressed below the skin s surface. [Pg.323]

Dissociative anesthetic A drug that produces significant analgesia while the patient remains awake and feels removed from the surrounding environment, without depressing vital signs. [Pg.130]
