We consider one-dimensional systems of self-gravitating sticky particles with random initial data and describe the process of aggregation in terms of the largest cluster size Ln at any fixed time prior to the critical time. The asymptotic behavior of Ln is also analyzed for sequences of times tending to the critical time. A phenomenon of phase transition shows up, namely, for small initial part...

The effect of oral administration of 20% alcohol (10 ml/kg BW) on haematological and reproductive parameters in female albino rats were investigated. The alcohol was orally administered for 30 days for haematological study, but administered orally for 21 days for estrous cycle study. Treatment of rats with 10 ml/kg BW of alcohol caused significant (p<0.05) reductions in the RBC and lymphocyte c...

Monitoring inter-organizational business processes requires explicit knowledge about when activities start and complete. This is a challenge because no single system controls the process, activities might not be directly recorded, and the overall course of execution might only be determined at runtime. In this paper, we address these problems by integrating process monitoring with sensor data f...

Proestrous female rodents are protected from the deleterious effects of trauma-hemorrhage that are observed in males. We hypothesized that the gender dimorphic outcome after trauma-hemorrhage might be related to gender differences in endothelial function and organ perfusion under such conditions. Male and cycle-matched proestrous female Sprague-Dawley rats underwent a midline laparotomy, hemorr...

Cognitive function can be affected by the estrous cycle. However, the effect of the estrous cycle on synaptic functions is poorly understood. Here we show that in female rats, inhibitory-avoidance (IA) task (hippocampus-dependent contextual fear-learning task) drives GluA2-lacking Ca2+-permeable AMPA receptors (CP-AMPARs) into the hippocampal CA3-CA1 synapses during all periods of the estrous c...

Effects of intraperitoneal injections of sodium selenite (2.0 and 4.0 mg/kg body weight) to normally cycling female albino Wistar rats daily for 30 days, and of single injection either during proestrous or oestrous and at each stage of the 4-day oestrous cycle were determined on oestrous cyclicity, ovarian follicles, ovulation, implantation and pregnancy outcome on day 14 of gestation. Administ...

background: low-level laser therapy (lllt) has shown a promising effect in ameliorating symptoms of rheumatoid arthritis (ra). the aim of this investigation was to compare the early and late antiinfl ammatory effects of lllt and betamethasone in ra. materials and methods: in this animal experimental study, after inducing a model of ra in temporomandibular joint (tmj) of 37 wistar rats using adj...

introduction in spite of its short time period compared with the earth long evolution history, quaternary has had a significant effect on the final formation of the landforms and vital resources. it is the final analysis of these levels and fully dependent on the earth genetic diseases and, above all, significant climate changes that have happened during this period. gavkhouni basin morphologic...
