As the name indicates, a renewal process is one that “renews” itself regularly. That is, there is a sequence of times {Tn, n ∈ Z} such that the process after time Tn is independent of what happened before that time and has a distribution that does not depend on n. We have seen examples of such processes before. As a simple example, one could consider a Poisson process with jump times Tn. As ano...

BACKGROUND The use of a single national figure fails to capture the complex patterns and inequalities in early childbearing that occur within countries, as well as the differing contexts in which these pregnancies occur. Further disaggregated data that examine patterns and trends for different groups are needed to enable programmes to be focused on those most at risk. This paper describes a com...

This study was an attempt to investigate demotivating factors among Iranian EFL language institute teachers in terms of years of teaching experience. To this end, the researchers tried to utilize a questionnaire as a research method. To collect data, a valid...

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...

Self-management training is one of the ways to empower patients to cope with disease. The aim of this before-and-after quasi-experimental study was to determine effects of a teach-back self-management training method on breast cancer patient happiness. Fifty breast cancer patients who visited the Park-e Neshat Limited Surgery Clinic in Kerman, Iran were randomly divided into intervention and co...
