Mass transfer with speciﬁed velocity ﬁelds Mass transfer can alter the velocity ﬁeld in a given situation. Mass transfer can drive individual species in a different direction from that of the imposed ﬂow (which is driven by, say, a pressure gradient. As a concrete example, consider a laminar ﬂat-plate boundary layer ﬂow in which species i is transferred from the wall to the free stream, as shown in Fig. Hence, we expect the velocity ﬁeld to be inﬂuenced only slightly by mass transfer from the wall, so that v is essentially that for the Blasius boundary layer. It follows that the boundary layer approximations are applicable and that the species equation can be reduced to ∂m ∂m ∂2m i i i u + v =Dim (11. Integrating and applying the boundary conditions, m2(x = 0) = m2,0 and m2(x = L) = m2,L, we obtain the concentration distribution: 1 2 x m2(x) = m2,0 + m2,L − m2,0 L and the mass ﬂux is then ρD21 1 2 n2 j2 =− m2,L − m2,0 (11. Vapor leaving the liquid surface diffuses through the gas in the tube and is carried away by the gas ﬂow across top of the tube. If the gas stream itself has only a relatively small concentration of vapor, then diffusion is driven by the higher concentration of vapor over the liquid pool that arises from the vapor pressure of the liquid. If the liquid species has a higher molecular weight than the gas species, the density of the mix- ture in the tube decreases with the height above the liquid surface. There is a net upward ﬂow of evaporating vapor in the steady state but a negligible downﬂow of gas (assuming that the liquid is saturated with the gas and thus is unable to absorb more. For the gas in the tube to have a net diffusion ﬂux when it is stationary, there must be an induced upward convective velocity against which the gas diffuses. This problem may be generalized to a stagnant horizontal layer of 588 An Introduction to Mass Transfer §11. The components will diffuse across the layer and, in general, may each have a nonzero mass ﬂux through the layer. If there is no imposed horizontal velocity, the mass transfer will induce none, but there may be a net vertical veloc- ity produced by the upward or downward transfer of mass. In this section, we analyze the general problem of steady mass transfer across a stagnant layer and then consider some particular cases. The results obtained here form an important prototype for our subsequent analyses of convective mass transfer. The solution of the mass transfer problem begins with an appropri- ate form of the equation of species conservation. Since the mixture com- position varies along the length of the tube, the density varies as well. However, if we take the temperature and pressure to be constant, the molar concentration of the mixture does not change through the tube. The system is then most easily analyzed using the molar form of species conservation. For one-dimensional steady mass transfer, the mole ﬂuxes N1 and N2 have only vertical components and depend only on the vertical coordi- nate, y. If the temperature and pressure can be taken as constant in the stagnant layer, so, too, can cD12. The ﬁrst boundary condition is x1 = x1,s at y = 0 and it requires that constant =−ln(Nsx1,s − N1,s) (11. This ratio, which depends on the spe- ciﬁc problem at hand, can be ﬁxed by considering the rates at which the species pass through the s-surface and forms the last boundary condi- tion. The e-surface in our analysis is at the mouth of the tube and the s-surface is just above the surface of the liquid. The gas ﬂow over the top may contain some concentration of the liquid species, x1,e, and the vapor pressure of the liquid pool produces a concentration x1,s. Only vapor is transferred through the s-surface, since the gas is assumed to be essentially insoluble and will not be absorbed into gas-saturated liquid. Thus, N2,s = 0, and Ns = N1,s = Nvapor,s is just the evaporation rate of the liquid. The ratio N1,s/Ns is unity, and the rate of evaporation is cD12 x1,e − x1,s Ns = Nvapor,s = ln 1 + (11. In this case, we obtain a single equation for N1,s = Nvapor,s, the evaporation rate: cD12 x1,e − x1,s Ngas + N1,s = ln 1 + (11. Once we have found the mole ﬂuxes, we may compute the concentra- tion distribution, x1(y), using eqn. Assume the helium stream at the top of the tube to have a mole fraction of water equal to 0. The vapor pressure of the liquid water is approximately the saturation pressure at the water temperature. The present analysis has two serious shortcomings when it is ap- plied to real Stefan tubes. First, it applies only when the evaporating species is heavier than the gas into which it evaporates. If the evaporat- ing species is lighter, then the density increases toward the top of the tube and buoyant instability can give rise to natural convection. Because a heat sink is associated with the latent heat of vaporization, the gas mixture tends to cool near the interface. The resulting temperature variations within the tube can affect the assump- tion that cD12 is constant and can potentially contribute to buoyancy effects as well. Since Stefan tubes are widely used to measure diffusion coeﬃcients, the preservation of isothermal conditions has received some attention in the literature. A mass-based analysis of convection problems often becomes more convenient than a molar analysis because it can be related directly to the mass-averaged velocity used in the equations of ﬂuid motion. The problem dealt with in this section can be solved on a mass basis, as- suming a constant value of ρD12 (see Problem 11. However, if the two species have greatly differing molecular weights or if the mixture composition changes strongly across the layer, then ρ can vary signiﬁ- cantly within the layer and the molar analysis yields better results (see Problem 11. Nevertheless, the mass-based solution of this problem provides an important approximation in our analysis of convective mass transfer in the next section. However, because of the strong inﬂuence mass transfer can have on the convective velocity ﬁeld, the ﬂow effects of a mass ﬂux from a wall must also be considered in modeling mass convection processes. The mass transfer coeﬃcient is developed in three stages in this sec- tion: First, we deﬁne it and derive the appropriate driving force for mass transfer. Next, we relate the mass transfer coeﬃcient at ﬁnite mass trans- fer rates to that at very low mass transfer rates, using a simple model for the mass convection boundary layer. Finally, we present the analogy between the low-rate mass transfer coeﬃcient and the heat transfer co- eﬃcients of previous chapters. In following these steps, we create the apparatus for solving a wide variety of mass transfer problems using methods and results from Chapters 6, 7, and 8. In the free stream, i has a concentration mi,e; at the wall, it has a concentration mi,s. This ratio is called the mass transfer driving force for species i: mi,e − mi,s Bm,i ≡ (11. If, for i,s example, n −n in a binary mixture, then m˙ is very small and 1,s 2,s both m1,t and m2,t are very large. The mass trans- fer rate may equally well be calculated using any species in a mixture; one obtains the same result for each. If species i is the only one passing through the wall, then n = m˙,so i,s that mt,i = 1. The evaporation of vapor from a liquid surface is an important example of single-species transfer. Only water vapor passes through the liquid surface, since air is not strongly absorbed into water under normal conditions. The most obvious way to do this would be to apply the same methods we used to ﬁnd the heat transfer coeﬃcient in Chapters 6 through 8—numerical or analytical solution of the momentum and species equations or direct ex- perimental simulation of the mass transfer problem. These approaches are often used for speciﬁc mass transfer problems, but they are one level more complicated than the analogous heat transfer problems, since the ﬂow ﬁeld is coupled to the mass transfer rate. Simple correlations and analytical formulas such as those used to calculate h are not so readily available for mass transfer problems. We instead employ a widely used approximate method that allows us to calculate gm,i from corresponding results for h in a given geometry by applying a correction for the effect of ﬁnite mass transfer rates.

Recently, multiple treponeme-specifc Traditional Syphilis Screening Algorithm (See Figure 5. Therefore, these tests can- not be used to screen for reinfection among patients with a history of syphilis. In practice, the prevalence of syphilis in the population tested signifcantly affects the utility of these rapid trepo- nemal tests—the positive predictive value for syphilis infection is signifcantly lower in patient populations with a low prevalence; in populations with a high prevalence, there is an increased likelihood that a positive treponemal result is due to persistent serofast reactivity from a previ- ously treated infection. If presumptive treatment is not administered, repeat serologic testing should be performed in 1 month and 3 months to rule out seroconversion following the recent exposure. If presumptive treatment is not administered, repeat serologic testing should be performed in 2–4 weeks to assess for syphilis seroconversion and rule out primary infection. In a patient presumptively treated for primary syphilis whose initial syphilis serology is negative, repeat serologic testing can be performed 2–4 weeks following the initial nonreactive result. Such retesting may detect early seroconversion and if reactive can confrm the syphilis diagnosis as well as establish a baseline titer useful in post-treatment follow-up. If the patient reports a recent exposure to a syphilis case, presents with a skin lesion suspicious for primary syphilis, has a high nontreponemal test titer (eg, >1:8), or is at increased risk for syphilis, repeat testing in 2–4 weeks might reveal further seroconversion (including reactive treponeme-specifc testing). If a patient is at high risk for syphilis and there is a signifcant risk of loss to follow-up, presumptive treatment could also be considered.

If a patient is at little or no risk of reinfection, further evaluation and management for possible treatment failure needs to be considered. Similarly, a patient report of resolved signs or symptoms which sound consistent with primary or secondary syphilis could erroneously point toward a diagnosis of early latent infection and result in under treatment if the fndings reported by the patient, in actuality, had a non-syphilitic etiology.

Anticoagulants and antiplatelet agents are used for deep venous thrombosis erectile dysfunction treatment south florida purchase tadala black 80 mg without prescription, together with short-term administration of intermediate doses of corticocteroids age related erectile dysfunction treatment cheap tadala black 80 mg on-line. Anticoagulation initially with heparin and then warfarin top 10 causes erectile dysfunction buy generic tadala black line, is recommended erectile dysfunction qof discount tadala black 80mg online, although thrombotic episodes may recur or progress despite anticoagulation. No controlled studies had been done comparing the anticoagulant or immunosupressive agents, intensity or duration of therapy required for vascular complications. The decision when to withdraw anticogulation needs to be based on the individual clinical situtation. Anticoagulant drugs should be given carefully in patients with pulmonary vessel disease because of the risk of potentially fatal hemoptysis. Isolated aneurysmal disease should be treated, where feasible, by surgical repair because of the high risk of rupture. Immunosupressive treatment, in combination with corticosteroids, is indicated postoperatively to prevent relapse. Behcet disease patients should carefully be scanned for possible multiple aneurysms in the pulmonary artery, abdominal aorta as well as in the iliac, femoral, and the popliteal arteries. In such cases, surgical treatment or stent-graft insertion should be performed, when feasible, for non-pulmonary arterial aneurysms because of a high risk of rupture. However, proper timing is essential and the possibility of an anastomotic aneurysm developing after surgery should be kept in mind. Similarly, invasive surgical procedures generally result in excessive infiltration of inflammatory cells into the treated areas with delayed wound healing at operative sites and subsequent anastomotic leakage despite any form of therapy.

Although the commonest age of development is in together of suﬃcient features in the individual patient the third decade of life, children may be affected with to satisfy the physician that a secure diagnosis can be apparently identical features [3]. Although these two terms However, it must be emphasized that in the absence of are sometimes thought to be readily exchangeable they any speciﬁc diagnostic feature, or clinical or laboratory are also the subject of debate and disagreement. To others, including the authors, a knowledge, of the condition, clinical suspicion and the lack of a known pathogenesis or a deﬁnitive dia- clinical judgement are the basis for diagnosis, although gnostic test, and the variability in prevalence and incid- assistance may be obtained from diagnostic criteria or ence of the condition and its constituent manifestations, a diagnostic tree as has been developed in Iran [24].

Cardiac disease Pericarditis, valve lesions and coronary artery involvement Valve lesions in seronegative uncommon; rarely intracardiac thrombi. Management, in the absence of knowledge of a cure of a condition of uncertain aetiology, must consist of the control of References symptoms and suppression of the inﬂammatory vascul- itis [37, 38].
