It has been recognized that the arc statistics of gravitational lensing is a useful probe of the density profile of clusters of galaxies. We examine several systematic effects which are important in predicting the number of arcs, with particular attention to the difference between tangential and radial arcs. First we derive an analytic expression of the cross section for radial arcs taking acco...
background & aim : the causes of increased rate of cesarean section (c-section) are not completely known. the repeated c-sections are frequently reported in studies conducted in iran. this study aimed to determine the frequency of, and indications for the first time csection (fcs) in zanjan, iran in 2012-2013. methods & materials : a cross-sectional study was conducted and systematic random sam...
The default mode network (DMN) is characterised by coherent very low frequency (VLF) neural oscillations in the resting brain. The attenuation of this activity has been demonstrated following the transition from rest to performance of a broad range of cognitive goal-directed tasks. Whether the activity of resting state VLF oscillations is attenuated during non-cognitive goal-directed tasks such...
ABSTRACT Background and objectives: The aim of this study was to investigate the effects of six months of aerobic exercise on lipid profile, inflammatory markers, and risk factors of cardiovascular disease in middle-aged obese women. Methods: Fifteen obese woman (age range: 35 to 45 y...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
To investigate the origin of spontaneous activity in developing spinal networks, we examined the activity patterns and synaptic organization of ventrally located lumbosacral interneurons, including those whose axons project into the ventrolateral funiculus (VLF), in embryonic day 9 (E9)-E12 chick embryos. During spontaneous episodes, rhythmic synaptic potentials were recorded from the VLF and f...
the aim of this study is investigating the effect of teaching “metacognitive strategies” on the way which scientific information retrieval workes by the using of google scholar searching machine on the students of ms in the psycology & education faculty of allameh tabatabayi university in 2007-2008 academic year. the statistical community was the students of ms in psychology & education facult...
دادههای VLF اثرات دوبعدی قابل ملاحظه را نشان میدهند. وارونسازی دوبعدی مزایای متعددی را هنگامی که روی دادههای پروفیلهای VLF اعمال میشوند، بیان میکند. نخست آنکه برآوردی کمی از هدایتویژههای سنگ کف به دور از رساناها فراهم میکند. دوم این که، ارتباط بین قسمتهای حقیقی و مجازی بردار تیپر، اطلاعاتی را در مورد عمق رساناها فراهم میکند. در این مقاله، یک مدل مصنوعی از یک همبری عمودی و یک پروف...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
[1] The controlled keying of ground-based VLF transmitters with periodic on/off sequences allows the detection of weak but measurable cross-modulation effects on other subionospheric VLF probe signals used for VLF remote sensing. In this paper, we reexamine previously published and additional cases of such events and determine that the initial interpretations of such cross modulation as being d...
