Acta Medica Iranica , 2002,
Abstract: Premature rupture of membrane (PROM) is one of the complications of pregnancy which is blamed for increasing the rate of cesarean. Therefore, we studied pregnant women who were admitted in Shariati hospital during March 1996 and March 2000, to determine the rate of cesarean delivery in cases with PROM after 36th week of pregnancy (Term PROM). In a retrospective study, we included pregnant women who had these criteria;1-PROM 2- Gestational age>36 weeks 3- Single pregnancy 4- cephalic presentation and 5- no prior history of cesaren delivery. We extracted their demographic factors, age of pregnancy, induced labor its absence, interval duration between the onset of PROM and induction of labor, interval duration between the onset of PROM and normal vaginal delivery or cesarean delivery, the circumstances of cervix before beginning of induction of labor, type of delivery, indications of cesarean section and new born weight, from their files and entered them in a check list.We reviewed 7544 cases and only 536 cases matched to our criten and were registered. The Rate of PROM and cesarean delivery in the study group was 7.5% and 28.06%, respectively. Indications of cesarean section contained; Fetal distress, 30.8% CPD, 27.3% failure to progress, 18.6% High risk pregnancy, 16.9% and Macrosomia, 6.4% the rate of cesarean section decreased significantly when cervix dilatation or effacement significantly when cervix dilatation or effacement (each alone) increased (Dil, p=5×10-7; Eff, p=7× 107). Interval duration between the rupture of amniotic sac and the onset of induction had no effect on the cesarean rate (p=0.58). An increase in induction cases did not increase the rate of cesarean section (p<107). PROM at 36th week of pregnancy and later did not increase the chance of cesarean delivery, and neither did not increase in induction rates. Longer interval duration between rupture of membranes and onset of induction played no role in decreasing the rate of cesarean section but it is possible to shorten hospitalization time by decreasing that interval duration without increasing cesarean rate. Thus, we suggest immediate induction of labor in the term PROM. PROM at 36th week of pregnancy and later didn’t increase the cesarean rate

Abstract: A study was under taken to investigate the effect of dietary supplementations of humic acid and esterified glucomannan) on broiler performance and the morphological measurements of small intestine. Two hundred and ten day old broiler chicks were weighed and randomly assigned to seven treatment groups in triplicate. The dietary treatments included T1) control (basal diet without any additives), T2) basal diets supplemented with 0.1% humic acid, T3) basal diets supplemented with 0.2% humic acid, T4) basal diets supplemented with 0.3% humic acid, T5) basal diets supplemented with 0.1% esterified glucomannan, T6) basal diets supplemented with 0.2% esterified glucomannan and T7) basal diets supplemented with 0.3% esterified glucomannan. Different parameters including body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR) and morphology of small intestine were evaluated during six weeks of experimental period. According to the results, at the end of experimental period, the highest average BWG were recorded in T4 group (fed with 0.3% humic acid), compared to control (T1) and other experimental groups (p < 0.05). Where as, the highest body weight gain were observed during starter period in treatment 7 (fed with 0.3% esterified glucomannan) as compare to other experimental groups (p < 0.05). Statistically, feed intake remained unaffected during the experimental period in all the treatment groups. However, the lowest and the highest feed intake were observed numerically within treatments T4 and T1 with 4229.70 g and 4362.30 g, respectively. Addition of dietary supplements used in the study appeared to have significant effect on the morphology of the small intestine (jejunum mucosal development) of the broilers in different treatment groups. Compared to control group, the inclusion of either humic acid or esterified glucomannon decreased (p < 0.01) the crypt depth and increased villus height respectively (p < 0.05). More ever, the diet supplements with humic acid 0.3% (T4) decreased crypt depth compared to esterified glucomannan and control. The dietary supplementations resulted in an increase in the villus height of intestinal mucosa of broilers. The increase in the villus height was associated with improvement of growth performance for both humic acid and esterified glucomannan. Based on our results it appeared that humic acid and esterified glucomannan can be used as a growth promoter in broiler diets and they can improve the gut health too.

Abstract: Background & Aim: It is important to measure the anxiety level in patients who undergo heart surgery and find out ways to relief it. This study aimed to determine the effect of cardiac rehabilitation program's first phase on the level of anxiety among patients hospitalized for coronary arteries bypass surgery. Methods & Materials: In this randomized clinical trial, sixty patients were selected using block sampling and randomly allocated into experimental and control groups. Data were gathered using a questionnaire including the spiel burger's standardized questionnaire. The level of anxiety was measured in both groups. Then, the first phase of cardiac rehabilitation program (including physical exercise, and daily living activities) was carried out in the experimental group. Finally, patients in the experimental group discussed their experiences of surgery. Control group Patients received usual care. The level of anxiety was measured in both groups the day before surgery and at the time of discharge. Data were analyzed using t-test, chi-square, and Friedman tests in SPSS. Results: Findings showed that the level of anxiety had no significant differences between two groups at the time of admission. After implementing the rehabilitation program, the level of anxiety decreased significantly (P<0.001) in the experimental group. Significant differences were observed in the level of anxiety between two groups after intervention (P=0.015) and at the time of discharge (P=0.038). Conclusion: This procedure should be used in surgery patients. Key words: anxiety, first phase of cardiac rehabilitation program, patients applying for coronary arteries bypass surgery
Tracking Using Continuous Shape Model Learning in the Presence of Occlusion
M. Asadi,C. S. Regazzoni
EURASIP Journal on Advances in Signal Processing , 2008, DOI: 10.1155/2008/250780
Abstract: This paper presents a Bayesian framework for a new model-based learning method, which is able to track nonrigid objects in the presence of occlusions, based on a dynamic shape description in terms of a set of corners. Tracking is done by estimating the new position of the target in a multimodal voting space. However, occlusion events and clutter may affect the model learning, leading to a distraction in the estimation of the new position of the target as well as incorrect updating of the shape model. This method takes advantage of automatic decisions regarding how to learn the model in different environments, by estimating the possible presence of distracters and regulating corner updating on the basis of these estimations. Moreover, by introducing the corner feature vector classification, the method is able to continue learning the model dynamically, even in such situations. Experimental results show a successful tracking along with a more precise estimation of shape and motion during occlusion events.

Journal of Science and Technology of Agriculture and Natural Resources , 2012,
Abstract: Modification of irrigation scheduling and management improvement of irrigation systems are two essential factors that have significant impact on agricultural water use efficiency. Therefore, a field experiment was conducted to evaluate the effect of tape drip irrigation (T) and furrow irrigation systems (S) under different irrigation regimes on yield and yield components of soybean in growing season of 2006-2007 at Gorgan Agricultural Research Station in north part of Iran. The experiment was laid out in a split plot design in a randomized complete form where each treatment was replicated three times. The main plots were irrigation systems of tape and furrow, and three irrigation regimes 100 (I100) , 75 (I75) and 50 (I50) percent of total irrigation requirement were chosen as secondary plots. Results showed that thousandgrain weight (gr) and plant height (cm) in furrow irrigation were significantly more than the tape drip irrigation method. Also significant differences between different irrigation regimes in terms of plant height, node numbers and yield were observed. So, I100 and I50 had highest and lowest values, respectively. In terms of irrigation system, 63 percent of water consumption was reduced in tape drip irrigation method. Also, the results indicated that higher and lower water use efficiencies were obtained from tape drip irrigation method with I50 treatment (1.09 kg m-3) and furrow irrigation with I100 treatment (0.50 kg m3), respectively.

Abstract: It is very important to understand the nature of digital media and its various categories and the position of this media and modern communication technology in the present social and political interactions. Explaining different kinds of discourses and different principles, theories, and conceptual models of the society along with the role of digital media is one of the most effective tools of information and culture in introducing the political system of Islamic Republic of Iran which is a religious democracy. A religious democracy is one of the aims of this study. In this study, a role of digital media in discourses of Islamic revolution was identified with a descriptive method. Also, there is no boundary in the virtual space. Therefore, relevant articles and studies were published about digital media and virtual diplomacy during the years of 2009 to 2013. Also, some of the relevant scientific books were studied. Digital diplomacy is a new tool in the world, to change attitudes and influence the thinking and beliefs of people today without invasion and war. In this context, digital media, because of the exceptional features like power to influence public opinion, international and cross-border charm and diversity, have great influence on the shaping of social changes and changing discourses. Hence development programs of making discourse using digital media, civil society and the international community can contribute to the development of the religious discourse of democracy. In this article, digital media and their effectiveness and usage in an introductory and discussion process were posed. Since people’s ideas are influenced a lot with digital media, digital media have a lot of effects on forming the social developments and discourse changes. Therefore, developing discourse programs with the use of digital media in internal and international communities can be effective in the development of Islamic revolution discourse.
Dynamical Joint Energy and Spinning Reserve Dispatch Considering Transmission Network Constraint
M. Asadi Bazardeh,M. Rashidi-Nejad
Journal of Applied Sciences , 2009,
Abstract: This study is dealing with ancillary services procurement and pricing in the new environment of electricity market. Spinning reserve is one of the most important ancillary services needed for satisfying reliability requirements as well as desired level of security in power systems. In deregulated power markets, generally two methods for energy and spinning reserve dispatching are addressed the so-called sequential dispatch and joint dispatch. It can be said that the sequential dispatch method may not be even feasible as well as optimal because of the coupling between spinning reserve and energy capacity. Therefore, in this study, a new method is proposed for dynamical joint energy and reserve dispatch that can solve the bottling of reserve problem by considering transmission limits. A genetic algorithm as an evolutionary optimization technique is used to solve such a complicated and non-convex problem. The proposed methodology is applied to a typical IEEE 30-bus system, while simulation studies show the effectiveness of joint energy and spinning reserve dispatch in comparison with the sequential dispatch.

Journal of Science and Technology of Agriculture and Natural Resources , 2011,
Abstract: In this study, the effects of enhancing synthetic chelators (HEDTA, EGTA) and low molecular weight organic acids (LMWOA) such as citric acid were compared on cadmium (Cd) solution in soils that were artificially contaminated. Also Cd phytoextraction capability by radish (Raphanus Sativus L.) was studied. The experiment was laid out in a randomized complete factorial design where each treatment was replicated three times. Concentration treatments of cadmium using CdCl2 were 0(control), 5, 20, 60 and 100 mg Cd kg-1. After complete growth of plants, 6, 20 and 20 mMkg-1 soil HEDTA, EGTA and Citric Acid were added per pot, keeping a control without any chelator application. In order to determine cadmium concentration ten days after adding chelates, samples were taken from the plants and soil of pots. The results showed that in all treatments the concentration of soluble Cd in soil was higher than the control. Also the results showed that synthetic chelators as compared with LMWOA (Citric Acid) have increased the solution remarkably. Among the other chelates, HEDTA had significant effects on Cd solution. In the current study, Cd concentration in shoot and root of (Raphanus Sativus L.) was increased with enhancement of Cd concentration in soil. Cd concentrations in shoots of radish were higher than those in roots. This could refer to higher bioavailability and solubility of Cd. In the current study, in all the treatments with HEDTA Cd concentrations in shoot and root of (Raphanus Sativus L.) were increased as compared with other chelates..
