The amount of fretting damage increases in an approximately linear manner with these variables, once the Initial stages of fretting are completed. A number of deviations from linearity have been reported, especially with respect to load, where it is often found that there is a tendency for the relationship to become parabolic in form. The superposition of a normal vibratory component of load can cause a very considerable increase in the wear rate ... [Pg.1330]

The ratio of the Komolgorov length scale and the diameter of the microcarriers correlate with cell damage. Several researchers show that if the ratio falls below one, cell damage increases significantly [34-38]. The size of the smallest... [Pg.129]

Release of markers bound to the endothelial cell such as thrombomodulin is indicative of vascular damage. Increased levels of soluble thrombomodulin in plasma are diagnostic (93). Other endothelium-derived markers such as 6-keto-prostaglandin F a, which is a metabolite of prostacyclin, are useful in the assessment of endothelial function, with lower levels indicative of inability to synthesize this marker due to defective or damaged endothelium through plaque formation (93). [Pg.155]

Increasing KC1 concentration lowers inhibition as shown in Table II. The fact that damage increased with KC1 concentration is consistant with the ionic ratio hypothesis and suggests a base exchange mechanism whereby calcium ions are more easily extracted from the clay and replaced by potassium ions as the potassium concentration increases. [Pg.623]

There is a number of alternative Raman imaging techniques these include using the Hadamard transform technique [25-27], and such as fibre-bundle image compression, which however is not yet commercially available [26-31]. However in the latter approach, the laser power on the sample could be high, since the beam is not defocused, and the possibility of sample damage increases. [Pg.534]

The superoxide anion (O2 ) exhibits numerous physiological toxic effects including endothelial cell damage, increased microvascular permeability, formation of chemotactic factors such as leukotriene B4, recruitment of neutrophils at sites of inflammation, lipid peroxidation and oxidation, release of cytokines, DNA singlestrand damage, and formation of peroxynitrite anion (ONOO-), a potent cytotoxic and proinflammatory molecule generated according to equation 7.210 ... [Pg.270]

The methods of control include selection for resistance or field tolerance and Manis has announced excellent clones of this type that, remarkably enough, include resistance to both Phytophthora and Dothidella. The other control is by fungicides. Of several sprays tried, Dithane with sticker gave best results. Under usual moist weather conditions, applications are put on at 8-day intervals. During the more severe rainy season it is necessary to spray as often as twice a week. However, when continuous rainfall occurred for 10 days or more without cessation, and no spraying was possible, Phytophthora damage increased, and it was a struggle to get the disease under control when less difficult conditions returned. [Pg.37]

As with other antiarrhythmics, in the elderly or patients with marked previous myocardial damage, increase dose more gradually during initial treatment phase. [Pg.447]

Endocrine and paracrine effects of cytokines and secondary mediators lead to vasodilation and hypotension, hyperactivation of coagulation systems, endothelium damage, increase of leukocyte adhesion as a resnlt of reduced perfusion and hypoxia. [Pg.285]

Many chemicals react with DNA, especially its bases, leading to various types of DNA damage. Increasing numbers of chemicals that can damage DNA are being... [Pg.458]

If the damage increases, the core transfers to inadmissible condition, and the reactor installation running must be stopped. In such a case, fuel composition contacts directly with coolant that is evidenced by a-activity therein. [Pg.249]

It is well known that lipid peroxidation, DNA singlestrand breaks, and other forms of DNA damage occur in response to oxidative stress (Ames et al, 1982). Depletion of reduced glutathione also commonly precedes or accompanies lipid peroxidation and oxidative stress (Muldoon and Stohs, 1991 Omar et al, 1990). In an in vivo study, the effects of ricin administered orally on hepatic lipid peroxidation, nonprotein sulfhydryl content, and DNA singlestrand breaks were assessed in mice (Muldoon et al, 1992). The incidence of hepatic DNA damage increased 2.9-, 2.8-, and 2.4-fold relative to control values at 24, 36, and 48 h post-treatment with ricin, respectively. Hepatic nonprotein sulfhydryl concentration decreased significantly from 51 to 65% to control values at 24, 36, and 48 h post-treatment (Figures 25.2 and 25.3). [Pg.345]

Comparison of several techniques (namely Fourier transform infrared spectroscopy (FTIR), simultaneous thermogravimetric analysis-differential scanning calorimetry (TGA-DSC) and ultrasonic spectroscopy) for assessing the residual physical and mechanical characteristics of polymer matrix composites (PMCs) exposed to excessive thermal loads showed the measured power spectra of ultrasonic energy to correlate with performance of graphite fibre epoxy matrix composites exposed to thermal degradation, and also that analyses with the three techniques all pointed to the same critical temperature at which thermally induced damage increased sharply [58],... [Pg.365]
