Ram pressure stripping is an important process in the evolution of both dwarf galaxies and large spirals. Large spirals are severely stripped in rich clusters and may be mildly stripped in groups. Dwarf galaxies can be severely stripped in both clusters and groups. A model is developed that describes the stripping of a satellite galaxy’s outer H i disk and hot galactic halo. The model can be ap...
the thesis has been arranged into five chapters and mainly concerned with the baer-invariant of groups which is the generalization of the schur-multiplier with respect to the variety of groups. chapter one is devoted to collect some notation and background information which are needed in the next chapters. its also contains some important statements which will be generalized in this thesis. cha...
conclusions garlic powder consumption can reduce blood pressure, yet in this model, it did not have an effect on the interaction between renin angiotensin system and nitric oxide inhibition. results at the beginning and at the end of experiments, systolic blood pressure was higher in the hypertensive groups than the normotensive group. however, at the end of the study, diastolic blood pressure ...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
chapter one is devotod to collect some notion and background informations, which are needed in the next chapters. it also contains some important statements which will be proved in a more general context later in this thesis. in chapter two, we show that if the marginal factor-group is of order np1...pk,n>1, then we obtain a bound for the order of the verbal subgroup. also a bound for the bear-...
abstract background: hypertension in pregnancy is one of the prevalent disorders resulting in maternal death. the aim of this study was to investigate the effect of stretching exercise and walking on changes of blood pressure in nulliparous women during pregnancy. materials and methods: this was a quasi-experimental trial that consisted three groups of women who took part in pre- and post-tests...
the effects of pentoxifylline on the wound healing process in a rat experimental pressure sore model
introduction: the present study used a histological evaluation method to examine the effects of pentoxifylline (ptx) on healing an experimentally-induced pressure sore in a rat model. materials and methods: there were 36 adult male rats used in this study. under general anesthesia and sterile conditions, we used forceps to create one pressure sore on each rat. a double layer of folded skin from...
