in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
objective(s) cyclooxygenases (coxs) are known to play some roles in physiological mechanisms related to learning and memory. since sodium salicylate is an inhibitor of cox, we have evaluated the effect of peripheral and intra-hippocampal administration of sodium salicylate on spatial learning and memory in male rats. materials and methods male rats were studied in two groups; the first group r...
Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.
Physiological studies confirm improvement of memory by Olibanum, a resin from Boswellia species, while little is known about the molecular mechanism by which it affects memory performance. Two master transcription factors, CREB-1 and CREB-2, regulate downstream memory-related genes expression, leading to the long-term memory potentiation. This study addresses the effects of Beta-boswellic acid ...
since anethum graveolens (dill) has phytoestrogenic compounds and it is proven that estrogens exert beneficial effects on cognition; the aim of this study was to understand if this plant can improve memory performance. male balb/c mice weighing 25-30 g were used in this study and memory was assessed by the novel object recognition task. in this method, the difference in the exploration time bet...
Background: Many studies have shown that about 45-65% of multiple sclerosis (M.S) patients suffer from cognitive impairments. Semantic memory as one of the subcategories of cognition is quite important for effective communication. In the present study, category-semantic memory was studied in order to evaluate the semantic memory organization in normal individuals and MS patients. Methods: Nine...
abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
Sleep has been shown to affect the consolidation of motor memory in adults. However, sleep-dependent consolidation is not well-specified in children as like as adults. So, the purpose of this study is to investigate the effect of sleep on childrenchr('39')s motor memory consolidation. The participants were 32 voluntary boys aging from 10 to 12 years old from city of Kerman, which had the necess...
Introduction and purpose: With increasing age, cognitive impairment such as memory loss is considered as a natural process in which initially, short-term memory is affected. Recalling memories usually is a conceptual approach to evaluate and review the events of life and is considered as a psychological process. The aim of this study was to examine the effectiveness of group memory recall on th...
