A novel yet simple, rapid and robust thermometric endpoint titration (TET) method for the determination of sodium in various foodstuffs is described. Sodium reacts exothermically with aluminium in the presence of an excess of potassium and fluoride ions to form NaK2AlF6 (“elpasolite”). This reaction forms the basis of a robust, reliable analytical procedure suitable for routine process control....

It is known that bootstrapping maximum for estimating the endpoint of a distribution function is inconsistent and subsample bootstrap method is needed. Under an extreme value condition, some other estimators for the endpoint have been studied in the literature, which are preferrable to the maximum in regular cases. In this paper, we show that the full sample bootstrap method is consistent for t...

background & objectives:airq software proved to be a valid and reliable tool to estimate the potential short term effects of air pollution. in this study the airq2.2.3 model was used to evaluate adverse health effects caused by nitrogen dioxide(no2) exposure in ahvaz during 2009. materials & methods:the airq,developed by the world health organization (who) to predict health endpoints a...

I review recent developments in the study of strongly interacting field theories with non-zero chemical potential µ. In particular I focus on (a) the determination of the QCD critical endpoint in the (µ, T) plane; (b) superfluid condensates in Two Color QCD; and (c) Fermi surface effects in the NJL model. Some remarks are made concerning the relation of superconductivity with the sign problem.
