in regions where the structure is built on the soil usually seismic waves propagate through hundreds of kilometers of rock and just tens of meters of soil layers but the most changes in properties of the waves occur when they propagate through soil layers. site response analysis is the study of propagating of earthquake waves from bedrock to the ground surface .although the traditional site response analyses were performed in the frequency domain ground motion in the time domain was used as the input motion.<\div>

in this work the particle swarm optimization is used as an optimization optical rectification coefficient for square double quantum wells by combining this algorithm together with bumerical solution of schrodinger equation and using the density matrix method we found the wells structure that the optical rectification coefficient is maximum.<\div>

The aim of this study was to determine the effectiveness of improving in Executive Functions in children with Mathematics Learning Disorder in the students of Fourth and fifth grade primary school in the Torbat–e–jam city. The study samples were all the boys and girls studying in the fourth and fifth grade in primary schools in the academic year of 1393–1394 in Torbat–e–jam city that had mathematical learning disorder. To determine the sample from the students referred to the problem center we selected 30 available samples from the Students and randomly divided into two groups: control and test. Group test for 10 hours in 30 individual sessions received enhanced executive functions. Research Tools were Wechsler3 and Persian key–math3 as pretests. Wechsler test to ensure the Students didn’t have Mental retardation and Persian key–math3 test for the evaluation of mathematical problems as a pre–test and post –test. The results of analysis of covariance showed that there is significant difference between control and test groups (p=.006andp=0.000).it means that improving in Executive Functions is effective in children with dyscalculia.<\div>

Carum carvi L. (Apiaceae family) or caraway is a common household plant grown around the world including Iran. Caraway fruits are used as flavoring agent in foods and beverages, and have various traditional uses in ethnomedicine. Anti–inflammatory, spasmolytic, antimicrobial, antioxidant, carminative and immunomodulatory properties of caraway suggest that it might exert beneficial effects on inflammatory bowel disease (IBD). Therefore, this study was carried out to investigate the effects of caraway hydroalcoholic extract (CHE) and its essential oil (CEO) in an immunological model of colitis in rats induced by trinitrobenzene sulfonic acid (TNBS). Different doses of CHE (100, 200, 400 mg\kg) and CEO (100, 200, 400 ml\kg) were administered orally (p.o.) and also doses of CHE (100, 400 mg\kg) and CEO (100, 400 ml\kg) were given intraperitoneally (i.p.) to the separate groups of male Wistar rats (n=6). Administration of the doses started 6 h after induction of colitis and continued daily for 5 consecutive days. Wet colon weight\length ratio was measured and tissue damage scores as well as indices of colitis were evaluated both macroscopically and histopathologically. CHE and CEO at all doses tested were effective in reducing colon tissue lesions and colitis indices and the efficacy was nearly the same when different doses of plant fractions were administered p.o. or i.p. Administration of prednisolone (p.o., 4 mg\kg), Asacol® (mesalazine microgranules, p.o., 100 mg\kg) and hydrocortisone acetate (i.p., 20 mg\kg) as references were effective in reducing colon tissue injures as well. These data suggest that caraway fractions are both effective and possess anti–colitic activity irrespective of the dose and route of administration.
