We derive cooling rate and coefficient of performance as well their variances for a quantum Otto engine proceeding in finite-time cycle period. This machine consists two driven strokes, where the system isolated from heat reservoir undergoes unitary transformation, isochoric steps, system-bath interaction durations take away equilibrium even at respective ends stages. explicitly calculate stati...

melanocortin- 4 receptor (mc4r) and agouti- related peptide (agrp) are involved in energy homeostasis in rats. according to mc4r and agrp effects on luteinizing hormone (lh) secretion, they may influence the estrous cycle of rats. therefore, the aim of this study was to investigate the expression of mc4r and agrp mrnas at different stages of estrous cycle in the rat’s hypothalamus. the estrous ...

Background: Ultrasound is preferred as first imaging modality in the study of the female pelvis. In this article, we have tried to mention 8 points that each midwife or nurse needs to know for planning the time of sonography and analysis of findings. Results: During the menstrual cycle, all pelvic organs are influenced by cyclic changes. Thus, pathologic conditions of pelvis need to be well ass...

In this paper we consider an imperfect production system which produces good and defective items and assume that defective items can be reworked. Due to the nature of rework process we do not restrict the rework rate to be equal to normal production rate or constant and assume that it is a random variable with an arbitrary distribution function. We also assume as it is true in most real world s...

Background: Acute-phase proteins (APPs) may be increased due to different stresses during estrus phase in farm animals. Aims: Determining changes of APPs at different phases of non-synchronized estrous cycle group (NSEG), and Ovsynch-synchronized estrous cycle group (SEG) in Holstein cows. Methods: Twelve non-pregnant clinically and paraclinicaly healthy Holstein cows with a body condition scor...

In this paper, we provide theoretical justification for the application of higher degree fuzzy transform in time series analysis. Under the assumption that a time series can be additively decomposed into a trend-cycle, a seasonal component and a random noise, we demonstrate that the higher degree fuzzy transform technique can be used for the estimation of the trend-cycle, which is one of the ba...
