This study is kind of semi imperial and its aim is survey influence music therapy in improve dimwitted students mind centralization that effected to attention deficiency disorder and hyperactive with wisdom age 5-7 years in Mashhad exceptional school that done in academic year (87-88). Sample people are 2 groups, 30 test and control (15 girls and 15 boys in every group) that choose from dimwitted students that studying in 15 schools exceptional child's each available sampling method for collecting data. For collecting data accomplish intelligence scale and Vesler (cyplogvaphy B) in 2stages before test and after test for all the people. Data analyze don with SPSS software and using median descriptive scale and standard deviation and illative scales of test T. results of data analyze shown (intervention therapy) is effective in improvement memory centralization for dimwitted girls students.

A first principles study of the electronic and optical properties of the graphene-like Tin+1Xn (n=1,2; X=N,C) has been done in the framework of the Density Functional Theory (DFT) to obtain associated quantities as the dielectric function, energy-loss function, reflectivity and absorption spectra. Results infer to a metallic property, stronger for titanium nitrides than titanium carbides owing to an extra electron in nitrogen atom compared to carbon, as well as a decreasing DOS at the Fermi level as the thickness of the layer increases. The optical studies for horizontal E||x and vertical E||z applied fields at low energies (0-20 eV) reveal a forbidden interval of radiation in the real part of the dielectric function along with a non-zero static dielectric amount at zero energy, exclusively definable for the E||z case of course. But in the imaginary part of the dielectric function some peaks are observed owing to the inter-band transitions. For both types of the applied fields, the plasmonic peaks in the energy loss functions of these compounds indicate a reflectivity of 100% in energies less than 1 eV for E||x case, just in contrast to the E||z. © 2014 Elsevier Ltd.

Salvia leriifolia Benth. (Lamiaceae) is a medicinal plant with analgesic, hypoglycemic and anti-inflammatory properties. Many of the beneficial effects of Salvia spp. are attributed to the phenolic compounds. The present study aimed to determine the amounts of rosmarinic acid, salvianolic acid B and caffeic acid in the roots, leaves and calli of S. leriifolia using a simple, rapid and efficient HPLC method. In addition, the effect of different combinations of 2,4-dichlorophenoxyacetic acid and kinetin-as growth regulators-on phenolic composition was evaluated. The results indicated that the 3 phenolic acids were well separated using the applied gradient HPLC system [C18 (5μm) column; phosphoric acid 1% and methanol as mobile phase]. Limit of detection and quantification values for rosmarinic acid, caffeic acid and salvianolic acid B were 0.2 and 0.5, 1.0 and 2.0, and 0.5 and 1.0μg/mL, respectively. Inter- and intra-day variations for rosmarinic acid, caffeic acid and salvianolic acid B were 2.8% and 3.4%, 2.4% and 3.5%, and 4.8% and 4.7%, respectively. Recovery values for the 3 phenolic acids ranged from 96.3% to 98.9%. Rosmarinic acid was the most frequent phenolic acid in the ethanolic extract of roots, leaves and calli of S. leriifolia (0.33, 4.65 and 6.39 mg/g dry extract, respectively) followed by salvianolic acid B (0.11, 0.13 and 0.10 mg/g) and caffeic acid (0.15, 0.20 and 0.07 mg/g). The highest dry weight (0.226 g) of callus was achieved in medium containing 2 mg/L 2,4-D and 1 mg/L KIN. To conclude, the present study indicated that rosmarinic acid is the major phenolic acid in the roots, leaves and calli of S. leriifolia, using a simple, rapid, efficient and reproducible HPLC method for the separation and simultaneous determination of phenolic acids. Moreover, the content of evaluated phenolics was found to be higher in the leaf extract vs. root and callus extracts of the plant. © 2014 Copyright Taylor & Francis Group, LLC. Source

Emotional disclosure has a significant impact on physical and psychological health. In this study porpoise is the effect of written emotional disclosure on the emotional regulation difficulties in students. The sample was 40 of Sistan and Baluchestan University; participants were in both control and experimental groups and completed the emotional regulation difficulties scale of (DERS) before intervention and after the first session and a month later. Repeated measures analysis of covariance is increase in experimental croup compare control group in post-test and decrease in Follow-up tests. Disclosure and more treatment sessions are required in order to reduction of emotional regulation difficulties. Source

The aim of the present study is to investigate the effect of the intervention based on the increasing awareness of psychosocial pathologies due to premature marriages on the mothers and daughters' attitude in Roshtkhar. The study was conducted in the framework of a Quasi-experimental design of two-group type with pretest-posttest and a one-month follow-up. The population of the study consists of all mothers and daughters of Roshtkhar; and the sampling was done through a cluster-random method. The subjects were divided into two groups of experimental and control. The subjects in the experimental group received the educational interventions for mothers and daughters, but the control group did not receive any intervention. The instrument for the study was a researcher-made questionnaire named "attitude towards premature marriage". This questionnaire consisted of 3 components of social, mental-emotional injuries and family harms, and 8 scales of attitudes towards addiction, sexual issues, suicide, house escaping, social anxiety, family violence and aggression, mental pressure and family atmosphere in 98 items which investigated the mothers and daughters' attitudes toward premature marriage. Having used the factor analysis and principal component method and the item correlation with the total test, the validity of the instrument has been tested; and by the Cronbach alpha method the reliability of the test was checked, both of which were satisfactory. The result of the multivariate analysis of covariance and the pre-test scores of the daughters showed that in total the preventive interventions for premature marriage have caused changes in daughters' attitudes in the post-test and follow-up stages. The result of related T-test for the mothers also showed that in subscale, there has been a statistically significant difference in the post-test scores comparing those of pre-test in experimental group concerning the attitudes toward aggression, mental pressure, family harms and addiction.
