We show that descriptive complexity’s result extends in High Order Logic to capture the expressivity of Turing Machine which have a finite number of alternation and whose time or space is bounded by a finite tower of exponential. Hence we have a logical characterisation of ELEMENTARY. We also consider the expressivity of some fixed point operators and of monadic high order logic. Finally, we sh...

The epidemiologic studies are either descriptive or analytical studies. Descriptive studies include case reports, case series reports, cross-sectional studies, surveillance studies, and ecological studies whereas analytical studies are either experimental or observational. Case–control and cohort studies are the type of observational studies out of which the latter is usually the prospective st...

the use of locks with different forms, mechanisms and applications has been common for a long time in iran. among these locks we can point out the pendant combinated lock, in which two mechanisms are used simultaneously in a single body. employing a descriptive – analytical method, this study searches the reasons of using two mechanisms in these locks. problems such as: the use of these locks, ...

Here we present data to evaluate potential absorption of Bisphenol A through non-metabolizing tissues of the upper digestive tract. Concurrent serum and urine concentrations of d6-BPA, and its glucuronide and sulfate conjugates, were measured over a 24 h period in 10 adult male volunteers following ingestion of 30 μg d6-BPA/kg body weight in soup. The pharmacokinetic behavior of BPA and its met...
