The problems of the first-passage time (FPT) [1, 2] and the residence time (RT) [3] are very important issues in random walk theory. Moreover, several properties of diffusion and transport in disordered systems are based in this concepts. Here, we do not want to present a survey of the enormous literature in the field of mean firstpassage time (MFPT) and mean residence time (MRT) of random walk...

In a study of the timing mechanism of the chaperonin nanomachine we show that the hemicycle time (HCT) is determined by the mean residence time (MRT) of GroES on the cis ring of GroEL. In turn, this is governed by allosteric interactions within the trans ring of GroEL. Ligands that enhance the R (relaxed) state (residual ADP, the product of the previous hemicycle, and K(+)) extend the MRT and t...

In this study, an open, double-blind, randomized, two-period, two-group crossover design was conducted in 14 healthy volunteers to study the bioequivalence of a fixed-dose generic product. After administration of test or reference products to each volunteer, both active ingredients were determined simultaneously in plasma samples using a developed and validated HPLC-UV method, and pharmacokinet...

Abstract The growing number of elderly people who are at increased risk food insecurity for a variety reasons, including financial ones, requires the current situation to be monitored. purpose this research was therefore determine: (1) how older perceive their in terms security; (2) whether use any form external support; and (3) relationship between people’s perception security support from soc...

This article describes in detail a variety of home equity conversion plans and discusses their relevance for social security beneficiaries, as well as for the aged in general. Under these plans, a dormant asset--accumulated home equity--is converted into current retirement income. The plans vary: Some are debt instruments; others involve the sale and leaseback of the residence. Some provide inc...

Residence time is a critical factor in determining the size of an open face biofilter. Four test biofilters were constructed with media comprised of yard waste compost and brush chips to compare 8 s. and 4 s. residence time. Biofilter performance was monitored for ten months by measuring pressure drop, moisture content, odor threshold, hydrogen sulfide, and ammonia concentrations. Odor reductio...

Background: Food security has always been a major determinant behind development of malnutrition among the under 5 children India. Even after sustained efforts to alleviate this problem, we are still way in achieving our targets. Aims and Objectives: To assess prevalence determinants food security, find association with stunting wasting less than five years age. Materials Methods: This study wa...

The regulations of the European Union (EU) Council in 2004 are the basis of the deployment of electronic passports within the EU. Since then EU member states adopt the format and the access protocols to further electronic machine readable travel documents (eMRTD) like national electronic ID cards and electronic residence permits, respectively. The security protocols to communicate with an eMRTD...
