Based on previous researches and current research indoor contaminations in most of the time were more than outdoor contaminations. In according to, most of our times have been spent in indoor environments (85-90%), therefore, it is necessary to investigate indoor environments. Symptoms of sick building syndrome are Headache, dizziness, drowsiness. Unknown reasons of disease above mentioned and ...

The residence time of a single dye molecule diffusing within a laser spot is propotional to the total number of photons emitted by it. With this application in mind, we solve the spherically symmetric "residence time equation" (RTE) to obtain the solution for the Laplace transform of the mean residence time (MRT) within a d-dimensional ball, as a function of the initial location of the particle...

Experiments on granule transport and the mean residence time in a rotary horizontal drum with inclined flights showed that the granules can be transported steadily. A model for granule transport based on the analysis of granule motion and other studies on inclined drums was developed to calculate the mean residence time of the granules, and verification experiments under different conditions we...

The pharmacokinetics aspects of levofloxacin were studied in healthy and experimentally renal damaged Muscovy ducks after single intravenous (IV) and oral (PO) dose of 10 mg kg(-1) bwt. Following IV administration, elimination half-life (t 1/2( β )) and mean residence time (MRT) were longer in renal damaged ducks than in healthy ones. Total clearance (Cltot) in renal damaged ducks (0.20 L kg(-1...

purpose: reconstruction programs have two approaches: in-situ reconstructions and relocation. different experiences around the world show little acceptance of relocation programs by people which new sites were left or did not return to their pre-boom. meanwhile, estalkhkooh village relocation program shows vice versa. villagers not only accept their new relocated village but also are trying to ...

[1] Estimates of mean residence time (MRT) are increasingly used as simple summary descriptors of the hydrological processes involving storage and mixing of water within catchment systems. Current understanding of the physical controls on MRT remains limited, and various hypotheses have been proposed to explain its variability between catchments. We present a series of virtual experiments to in...

Evaluating biochars for their persistence in soil under field conditions is an important step towards their implementation for carbon sequestration. Current evaluations might be biased because the vast majority of studies are short-term laboratory incubations of biochars produced in laboratory-scale pyrolyzers. Here our objective was to investigate the stability of a biochar produced with a med...

Pyrogenic carbon (PyC) is an important component of the global soil carbon (C) pool, but its fate, persistence, and loss dynamics in contrasting soils and environments under planted field conditions are poorly understood. To fill this knowledge gap, a 13C-labelled biochar, as a surrogate material for PyC, produced from Eucalyptus saligna by slow pyrolysis (450°C; δ13C -36.7‰) was surface (0-10 ...

More and more Member States require immigrants from outside the EU to pass language or knowledgeof-society tests in different stages of the immigration and integration process. This article focuses on the application of this requirement as a condition for obtaining a permanent residence permit or the EU long-term resident status. It is based on an international comparative study that included s...

Since 1996, the Emilia-Romagna Region has been promoting screening programmes for cervical cancer, selecting resident women aged 25-64 as a target population. This analysis concerns a second round of screening performed in the city of Ferrara and its province. A total of 103,971 women were invited to be screened, but only 55.51% of them arrived on the day of the scheduled screening. We therefor...
