Leila Barati, Reza Biria
Open Journal of Modern Linguistics (OJML) , 2011, DOI: 10.4236/ojml.2011.12005
Abstract: Comprehension is closely related not only to the knowledge of words and syntax, but also the pragmatic concerns of the discourse. The purpose of the present study was to investigate the impact of the intonational clues selection of Iranian teenagers' and young adults’ Persian listening comprehension ability on their English learning as a second language. According to Buck (2003), in listening comprehension the input in the form of sounds and intonational clues often conveys additional information. In this study 60 male and female teenagers (13 - 19) and 60 male and female young adults (20 - 26) were selected randomly based on Oxford Placement Test (OPT). Each group was randomly assigned to two sub groups; namely, experimental (EX) and control groups (CG), 15 participants in each group. During the study two fiction and non-fiction passages, at first in Persian and then in English, were read to participants. The passages for participants in CG were read without applying speaker’s intonation changes but they were read for participants in EX with applying speaker’s intonation changes. In this study factors as age and gender are important because the results showed that the difference between two groups with different age ranges was significant, and participants’ inferencing, correct clue selection and listening comprehension ability in the experimental group was superior to the control group in the first language (Persian) and it also influenced positively second language learning and inferencing ability (English).

Hossein Haroonabadi, Hassan Barati
Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.32013
Abstract: Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In the present research, generation reliability is considered, and a method for its assessment is proposed using Game Theory (GT) and Neural Networks (NN). Also, due to the stochastic behavior of power markets and generators’ forced outages, Monte Carlo Simulation (MCS) is used for reliability evaluation. Generation reliability focuses merely on the interaction between generation complex and load. Therefore, in the research, based on the behavior of players in the market and using GT, two outcomes are considered: cooperation and non-cooperation. The proposed method is assessed on IEEE-Reliability Test System with satisfactory results. Loss of Load Expectation (LOLE) is used as the reliability index and the results show generation reliability in cooperation market is better than non-cooperation outcome.

Abstract: Background and objectives Wound repair after a surgical operation or traumatic injuries is a coordinated process, which is highly dependent to the pre- and post-operative or traumatic care. There is no consensus on the best wound care method and application of topical therapeutic agents including diluted oxygen peroxide solution and antibiotics. This study is aimed to compare the healing effects of oxygen peroxide and tetracycline ointment in management of traumatic facial injuries. Methods 76 patients divided into two groups were entered into this randomized clinical trial. All patients sustained facial injuries requiring primary repair. The first group received 2% topical oxygen peroxide solution for 5 days, and the second group received sterile 1% tetracycline topical ointment for 5days. At the end of the fourth day, wound healing status was assessed with a chart designed for this purpose. Results No statistically significant difference was observed between the tetracycline and hydrogen peroxide groups in regards to the distance of wound margins, erythema and dehiscence. Conclusion According to our results, there is no difference in the effects of hydrogen peroxide solution or tetracycline ointment on the healing of traumatic facial wounds.

Qom University of Medical Sciences Journal , 2012,
Abstract: headache are involved and can induce misdiagnosis in these patients. Many of these patients with nasal congestion believe that the cause of their headache is due to the sinusitis. The purpose of this study was to determine the frequency of nasal congestion in episodes of migraine headache. Methods: This was a cross-sectional and descriptive study on 131 patients which were diagnosed by neurologists based on standard criteria to have had migraine. Sampling was done through non-probability in hand method. The data were gathered with regard to age, sex, type of headache and presence of nasal congestion for each patient. They were then analyzed by chi-square and Fisher’s exact test (p<0/05). Results: Out of 131 patients 18 (13.7%) had nasal congestion in their migraine attacks. 19.8% of patients were male and 80.2 patients were female. There was no meaningful correlation between nasal congestion in migraine patients with their sex, age and type of headache. Conclusion: According to the results of the study there was no meaningful correlation between the type of migraine headache (classic and non-classic) and sex and age .

Asian Journal of Biomedical and Pharmaceutical Sciences , 2013,
Abstract: Nowadays, no-drug treatments (medicinal plants) are novel therapeutic approaches in the treatment of diabetes. Broccoli is a plant in the cabbage family, whose large flower head is used as a vegetable. The mass of flower heads is surrounded by leaves. Broccoli was derived from cultivated leafy cole crops in the Northern Mediterranean in about the 6th century. This study aimed at assessing the effect of Broccoli leaves extract on the blood glucose and lipid profile in diabetic rats. Thirty male adult rats were randomly selected and divided into three groups as nondiabetic control; diabetic control; diabetic rats treated with hydroalcoholic extract of Broccoli leaves. In diabetic groups, alloxan monohydrate (100 mg/kg) was injected intraperitoneally to develop diabetes. Then the Test group received intraperitoneal injection of hydro-alcoholic extract of Broccoli leaves (100 mg/kg). At last, glucose, cholesterol, triglyceride, HDL, VLDL, LDL and insulin contents of the rats' serum sample were determined. Diabetic rats treated with extract showed a significant decrease in blood glucose level (p<0.05). Furthermore, compared diabetic group, in the extract-treated rats, there was a significant decrease in serum contents of total cholesterol (TC) ,LDL,VLDL and TG, but a significant increase in insulin level and HDL (p<0.05). These results show that the hydroalcoholic extract of Broccoli leaves may be effective in the treatment of diabetes. This effect can be due to the presence of flavonoides and their antioxidant features
