Dilation variable

Adverse reactions associated with these drugs are variable Some of tire more common adverse reactions are listed in tire Summary Drag Table Peripheral Vasodilators and Miscellaneous Vasodilating Drags. Because these drugs dilate peripheral arteries, some degree of hypotension may be associated with their... 

Equation (6a) implies that the scale (dilation) parameter, m, is required to vary from - ac to + =. In practice, though, a process variable is measured at a finite resolution (sampling time), and only a finite number of distinct scales are of interest for the solution of engineering problems. Let m = 0 signify the finest temporal scale (i.e., the sampling interval at which a variable is measured) and m = Lbe coarsest desired scale. To capture the information contained at scales m > L, we define a scaling function, (r), whose Fourier transform is related to that of the wavelet, tf/(t), by... 

In the corresponding column-standardized biplot of Fig. 31.7 we find all representations of the eight chromatographic methods more or less at the same distance from the origin of space. The circle is distorted because of the large difference between the contributions of the first and second latent variables (95 and 4%) and the choice of a = [3 = 0.5 which has been made at the outset. The combined effect is an apparent dilation of the vertical axis. 

A clinically useful indirect estimate of Mvo2 is the double product (DP), which is HR multiplied by systolic blood pressure (SBP) (DP = HR xSBP). The DP does not consider changes in contractility (an independent variable), and because only changes in pressure are considered, volume loading of the left ventricle and increased MVo2 related to ventricular dilation are underestimated. 

Physiologic effects are relatively few. Dilated pupils, hyperreflexia, increased muscle tension, incoordination, and ataxia are common physical signs. Effects on pulse rate, respiration, and blood pressure are so variable that they probably represent varying levels of anxiety of subjects rather than true physiologic effects. Changes in appetite and salivation are inconstant, being increased in some subjects and decreased in others. 

Third, the metric tensor is determined by the variables 4>, //, A. On the other hand and v never appear in Eqs.(6)-(9) (reflecting the fact that x° and x5 constant dilatations are always possible without harming the commutator relations for the Killing motions), so these equations are of first order on 4>, / and A. However, the equations can be rearranged resulting in the following symbolic structure ... 

Intermediate-duration oral studies in humans for mirex are lacking. A review of the animal oral intermediate toxicity data for mirex indicates that the available studies are not adequate to derive intermediate oral MRL for mirex. The most suitable study provides a LOAEL of 0.25 mg/kg/day for endocrine effects-dilation of rough endoplasmic reticulum cisternae of the thyroid of weanling Sprague-Dawley rats (Singh et al. 1985). Adjusting the LOAEL of 0.25 mg/kg/day determined from this study with a total uncertainty factor of 1,000 (10 for use of a LOAEL, 10 for animal to human extrapolation, and 10 for interspecies variability) yields an intermediate oral MRL of 0.0003 mg/kg/day, which is lower than the chronic-duration oral MRL of 0.0008 mg/kg/day derived from an NTP (1990) study in rats (see chronic-duration MRL). Therefore, no oral intermediateduration MRL was developed for mirex. 

Thus, the nitrates enable myocardial flow resistance to be reduced even in the presence of coronary sclerosis with angina pectoris. In angina due to coronary spasm, arterial dilation overcomes the vasospasm and restores myocardial perfusion to normal. O2 demand falls because of the ensuing decrease in the two variables that determine systolic wall tension (afterload) ventricular filling volume and aortic blood pressure. 

Thus quite generally a dilatation invariant variable, which a priori depends on F scaling fields, can be reduced to a scaling function depending on F — 1 scaling variables,... 

Functional antagonism. Two agonists acting via different receptors affect the same variable (e.g., luminal diameter of bronchi) in opposite directions (epinephrine —> dilation histamine —> constriction). 

Addition of variable corneal compensator represents a significant improvement Progression analysis No pupil dilation required Race-based norms Portable... 

The overall effect of a sympathomimetic depends on the site of action (receptor agonist or indirect action), on receptor specificity and on dose for instance adrenaline ordinarily dilates muscle blood vessels (Pj mainly arterioles, but veins also) but in very large doses constricts them (a). The end results are often complex and unpredictable, partly because of the variability of homeostatic reflex responses and partly because what is observed, e.g. a change in blood pressure, is the result of many factors, e.g. vasodilatation (p) in some areas, vasoconstriction (a) in others, and cardiac stimulation (P).

To find the law of expansion under variable pressure, we must combine the above equations with Boyle s law. Boyle s law states that when we compress or dilate a gas at constant temperature, the volume and the pressure are inversely proportional to one another. The product pv, therefore, does not vary, i.e.. ... 

Three key variables in these studies are mouse strain, mouse sex, and technique. Strain was mentioned earlier sex is indicated in Table 3 and is discussed inSection7. Technique is a third key variable, whethermeasurements were made in mice under anesthesia or after some period of recovery from anesthesia, as given in Table 3. For example, anesthesia markedly decreases heart rate (HR), blood pressure (BP), and cardiac contractility and causes left ventricular dilation... 

In Eq. (12) each p(ry)a3 becomes p(iy) A3a3, in the potential that we have assumed to be radial we have a dilation of the distance i.e. v rij) is changed into v(Xrij) and an extra dependence in A appears in the logarithm term. Now we may shift the field into p(r, )A 1 that we may rename p(rj), as it is a dummy variable. Since the number of points in the discretization is fixed the new system has the same number of particles as before dilation. The scaling parameter A appears only in the pair potential and in the logarithm term. The derivative dln (A)/dA can be easily performed and after returning to the continuous expression we obtain,... 

This MRL was based on a NOAEL of 0.23 mg Hg/kg/day for renal effects in rats administered mercuric chloride 5 days a week for 6 months (Dieter et al. 1992 NTP 1993). This dose was duration-adjusted for a 5 day/week exposure and divided by an uncertainty factor of 100 (10 for extrapolation from animals to humans and 10 for human variability). Increased absolute and relative kidney weights were observed in rats exposed to 0.46 mg Hg/kg/day, the next higher treatment level. At higher doses, an increased incidence of nephropathy (described as foci of tubular regeneration, thickened tubular basement membrane, and scattered dilated tubules containing hyaline casts) was observed. Renal toxicity is a...
