An atmospheric vapor generator and a custom exposure chamber were used to measure the uptake of organic chemicals into silicone wristbands under simulated indoor conditions. LogKsamodels were evaluated using repeated k-fold cross-validation. Air equivalency was compared between best-performing models. Res...
The equilibrium expression for calcium hydroxide is shown below. Ksp = [Ca2+][OH–]2 Eq. 1 Equilibrium constants are temperature-dependent and the value of an equilibrium constant can be related to temperature and the Gibbs Free Energy, Gº, through the equation:...
When a heterogeneous group of people provide themselves with a pure public good the resulting Nash equilibrium outcome will divide the group into contributors and free riders. This paper proposes a general algorithm for discovering which individuals in the group fall into which of these two classes....
7.Bhasin S, Pencina M, Jasuja G, Travison T, Coviello A, Orwoll E, et al. Reference ranges for testosterone in men generated using liquid chromatography tandem mass spectrometry in a community-based sample of healthy nonobese young men in the Framingham Heart Study and applied to three geog...
calculated BDV values with an error rate of less than 10% regarding the BDV value. Thus, the ascertainment according to the disclosure is superior even to the results from the method according to IEC 60243-1 performed using standard BDV lab equipment, said method having an error rate of up ...
3. The cell assembly of claim 2 wherein the upper portion of the upper piston member operably engages an upper platen of a press, the lower portion of the lowermost lower piston member engages a lower platten of the press, and each cell body member is provided with a plurality of ports...
which served as a reference point for the comparison with the different FZD5micro-switch mutants. While none of the mutants enhanced the WNT-3A-induced TOPFlash response, many mutants showed an impaired response (Fig.3b). Most strikingly, the R6×32A molecular switch mutant completely abrogated ...
this approach to determining the intact stress–strain state in an unreinforced subgrade is legitimate, since when determining the stress from the soil’s natural weight and the train load, it can be assumed that the upper part of the subgrade is in a state of prelimit equilibrium, as well ...
In this reaction, F6P was converted in reverse to G6P as the reaction approached equilibrium. The time course is not shown to full equilibration; final concentrations were 5 and 2.8 mM for G6P and F6P respectively. TEP is an internal standard; (b) Reversible Michaelis–Menten equation (see...
focused on determining an objective mean value—a representative value of the results of the measured thickness of zinc layer deposited on individual samples for individual test runs performed at a constant current density of J = 2 [A·dm−2] and, of course, for the measurements on an ...
