Structural health monitoring has been widely used during the past decades to evaluate the safety of structural assets, detect damages at an early stage, and prevent unexpected and costly damages. The research works in this field are often concerned with bridges and buildings and little research has been conducted on structural health monitoring of power plant infrastructures such as machine foundations. The turbo generator, also referred to as the heart of the power plant, is supported by massive concrete foundations in the turbine hall of thermal power plants. Most TG foundations in thermal power plants are at or close to their design age. The reports on structural damages in thermal power plants show that cracks are frequently observed on the beams and columns of frame-type TG foundations. It is probably the most appropriate time for developing vigorous methods for health monitoring of power plant structures to extend their reliability and life span. This paper uses the vibration-based approach for damage detection of TG foundations. Analytical mode decomposition (AMD) and experimental mode decomposition (EMD) methods are both used for modal parameter identification. A genetic algorithm is further used for finite element model updating and damage detection. The performance of the method is investigated using a 3-D finite element model of a frame-type TG foundation.

Abstract Background Historically, Roux-en-Y gastric bypass (RYGB) has been considered the gold standard of bariatric surgery (BS). This procedure acts as a mixed restrictive and malabsorptive operation. Methods This retrospective cohort study included 410 morbidly obese patients (BMI > 40 kg/m2 or BMI > 35 kg/m2 along with at least one major comorbidity) who underwent primary laparoscopic RYGB surgery from 2009 to 2015 by a single surgery team. The patients were 18 years and older with at least 12 months of follow-up. Total weight loss (%TWL) and comorbidity resolution were compared in short-term (12 months) and mid-term (12–60 months) follow-ups. The primary and secondary outcomes were evaluating the effect of Roux-en-Y on weight loss and control of comorbidities, respectively. Results The mean ± SD age, weight, and BMI at surgery were 40.1 ± 10.58 years, 123.32 ± 19.88 kg, and 45.78 ± 5.54 kg/m2, respectively, and 329 (80%) were female, and 62 (15%) had T2DM. %TWL was significantly higher in T2DM patients 9 months postoperatively and after that. Patients with lower BMI (

Dr. Sayyed Abdolbaghi Modarres, the son of the martyr Ayatollah Sayyed Hasan Modarres, was born in Isfahan on Thursday, January 12th, 19051. He completed his primary education in this city. Having been elected as a leading mujtahid in the second term of the National Assembly in 1911, his late father emigrated to Tehran (Khajeh Nouri, 1978, pp. 3-7). He took his eldest son Sayyed Ismail with him and sent his other children to the town of Esfeh2 to stay with their mother temporarily. They were supposed to join their father after he found a suitable place in Tehran. However, due to the death of their mother, the children were forced to leave for Tehran earlier. After coming to Tehran, Sayyed Abdolbaghi received his primary education in this city and studied religious sciences in the Sepahsalar college, which was entrusted to Ayatollah Modarres by order of Ahmad Shah on July 18, 1925 (Modarresi, 1987, p. 164). He continued studying there until the age of 13.

It is eminent that the Islamic Republic of Iran is in a defensive position in the military field and within the framework of defense power in the region; So it has both weaknesses and threats; therefore, it should seek to minimize the losses caused by its threats and weaknesses by making fundamental changes in the process of military activities, merging several organizations with each other, and etc.

Abstract The most accepted procedures as conversion for poor weight changes after sleeve gastrectomy (SG), are malabsorptive surgeries. This study was designed to evaluate the 5-year outcomes of One Anastomosis Gastric Bypass (OAGB) following SG due to weight loss failure and weight regain. From September 2014 to January 2017, totally 23 patients with a history of SG conversion to OAGB in terms of weight loss failure or weight regain who had completed their 5-year follow-ups were studied. Some obesity related co-morbidities containing type-2 diabetes (DM), hypertension (HTN), dyslipidemia, obstructive sleep apnea (OSA) and gastroesophageal reflux disease (GERD) were also investigated at 1, 2, 3 and 5 years after conversional surgery. All cases had remission/improvement in DM, DLP, HTN and OSA 1 year after conversional OAGB. Analysis showed statistically significant (P

Abstract In patients with BMI ≥ 50 kg/m2, it is difficult to select an appropriate procedure that can lead to optimum results. This study aims to evaluate mid-term weight loss outcomes in patients with BMI ≥ 50 kg/m2 following one anastomosis gastric bypass (OAGB) as a one-stage procedure. A prospective study was conducted on patients with BMI ≥ 50 kg/m2, aged 18 years and above who had undergone primary OAGB from January 2016 to February 2019 with at least two years follow-ups. A total of 197 patients with BMI ≥ 50 kg/m2 had underwent OAGB. The mean age was 38 years and the mean pre-operative BMI was 53.7 kg/m2. Mean EWL% were 63.7%, 67.8% and 66.2% at one, two and five years after OAGB respectively. The highest level of EWL% was 68.4%, which was achieved in the 18th month following OAGB. OAGB can be performed safely in patients with BMI ≥ 50 kg/m2 as a one-stage procedure with acceptable weight loss outcomes and remission of obesity associated medical problems.

Compared to traditional methods based on mean response evaluation of seismic parameters with significant confidence margin, the growing use of the new generation of performance-based design methods, which are based on loss and financial assessment, necessitates an increase in accuracy and reliability in probabilistic evaluation of structural response for all values of seismic parameters. Even with the same limited number of common nonlinear analyses, utilizing the Bayesian approach, which allows the use of diverse and even inaccurate data to form beliefs, is a powerful method to predict and enhance seismic response results. In this paper, the practicability of using linear analysis data in a Bayesian inference model to predict nonlinear responses is evaluated. A 20-story reinforced concrete special moment resisting frame is being considered, and a Bayesian model for prediction of the maximum story drift and the peak floor acceleration has been investigated. The Bayesian model was developed on linear results and finally updated with a limited number of nonlinear results. The predictability power of predictors, Bayesian model comparison among different likelihood functions, and common diagnostics tools in numerical solution of the Bayesian model developed on linear results, have all been examined. The results demonstrate a significant improvement in the outcomes, while proving the practicability of developing a stable and reliable model based on linear analysis data.

Background: Tumor-associated hypoglycemia can be caused by non-islet cell tumors including gastrointestinal stromal tumor (GIST) which is a rare paraneoplastic syndrome that leads to the release of insulin-like growth factor-2 (IGF-2). Case Presentation: We report the case of a 45-year old woman who was admitted to our hospital with refractory hypoglycemic episodes. We found normal serum insulin and c-peptide level and abdominal CT-scan showed a small duodenal wall lesion suggesting insulinoma. After tumor resection, hypoglycemia symptoms were recovered, but the pathological findings demonstrated the lesion was GIST. Conclusion: In a small gastrointestinal lesion with hypoglycemic symptoms we should consider IGF-II secreting GIST in addition to insulinoma.

Abstract Background Burn is a tragic event for an individual, the family, and community. It can cause irreparable physical, mental, economic, and social injury. Researches well documented that a quick visit to a healthcare center can greatly reduce burn injuries. Therefore, the aim of this study is to identify the effective factors in the interval between a burn and start of treatment in burn patients by comparing three classification data mining methods and logistic regression. Methods This cross-sectional study conducted on 389 hospitalized patients in Imam Khomeini Hospital of Kermanshah city since 2012 to 2015. The data collection instrument was a three-part questionnaire, including demographic information, geographical information, and burn information. Four classification methods (decision tree (DT), random forest (RF), support vector machine (SVM) and logistic regression (LR)) were used to identify the effective factors in the interval between burn and start of treatment (less than two hours and equal or more than two hours). Results The mean total accuracy of all models is higher than 0.8. The DT model has the highest mean total accuracy (0.87), sensitivity (0.44), positive likelihood ratio (14.58), negative predictive value (0.89) and positive predictive value (0.71). However, the specificity of the SVM model and RF model (0.99) was higher than other models, and the mean negative likelihood ratio (0.98) of the SVM model are higher than other models. Conclusions The results of this study shows that DT model performed better that data mining models in terms of total accuracy, sensitivity, positive likelihood ratio, negative predictive value and positive predictive value. Therefore, this method is a promising classifier for investigating the factors affecting the interval between a burn and the start of treatment in burn patients. Also, key factors based on DT model were location of transfer to hospital, place of occurrence, time of accident, religion, history and degree of burn, income, province of residence, burnt limbs and education.

Background: A large liver size is a factor that may increase the difficulty of bariatric surgery (BS) and unwanted complications. Some agents have been used to decrease the liver size before BS. Silymarin has been used as an antioxidant agent to improve liver function tests. This study was designed to evaluate the effects of silymarin on liver dimensions, function, and lipid profile. Materials and Methods: A double-blind randomized clinical trial was performed on 56 patients. The patients were divided into silymarin and placebo groups. Blood samples and sonographic examinations were taken from the patients before and 4 weeks after the administration of the silymarin or placebo. In the first group, 140 mg silymarin was prescribed every 8 h for 4 weeks, and the other group received placebo in the same way with the same tablet shape. After the completion of the 4-week treatment, laboratory tests and ultrasonography were carried out again. Results: Thirty-nine (69.6%) patients were female with a mean body mass index (BMI) of 46.2 kg/m2 and a mean age of 36.8 years. Most of the patients had a compliance of 80% and higher. The analysis did not show any significant difference in aspartate transaminase, alkaline transaminase, liver size, cholesterol, and triglyceride changes among the silymarin and placebo groups. BMI loss was slightly higher in the silymarin group although the difference was not statistically significant. Conclusion: The present findings show that silymarin administration for 4 weeks does not affect liver size and function, but further evaluations should be carried out on the subject.

Objective: In the present work, the effects of different fractions of Coriandrum sativum (C. sativum), on pentylenetetrazole (PTZ)-induced seizures and brain tissues oxidative damage were investigated in rats. Materials and Methods: The rats were divided into the following groups: (1) vehicle, (2) PTZ (90 mg/kg), (3) water fraction (WF) of C. sativum (25 and 100 mg/kg), (4) n-butanol fraction (NBF) of C. sativum (25 and 100 mg/kg), and (5) ethyl acetate fraction (EAF) of C. sativum (25 and 100 mg/kg). Results: The first generalized tonic-clonic seizures (GTCS) latency in groups treated with 100 mg /kg of WF or EAF was significantly higher than that of PTZ group (p< 0.01). In contrast to WF, the EAF and NBF were not effective in increasing the first minimal clonic seizure (MCS) latency. Malondialdehyde (MDA) levels in both cortical and hippocampal tissues of PTZ group were significantly higher than those of control animals (p< 0.001). Pretreatment with WF, NBF, or EAF resulted in a significant reduction in the MDA levels of hippocampi (pConclusion: The present study showed that different fractions of C. sativum possess antioxidant activity in the brain and WF and EAF of this plant have anticonvulsant effects.

Feed-forward control of hysteretic systems is a challenging task due to the hysteresis nonlinearity. Hysteresis models are utilized not only for identification, but also for hysteresis control. The feed-forward control, which is not an error-based (feedback-based) algorithm, plays a significant role in hysteresis control problems. Instead, it works based on knowledge about the process in the form of a mathematical model of the process. In feed-forward control problems, it is important to identify the inverse relationship of the output and input of the system, i.e., determining the mapping of the output and input of the system plays a key role in feed-forward controlling. This paper presents a new feed-forward controller model to control an actuator in a laboratory to tackle the restrictions of feedback control systems. For this purpose, first, a numerical model of a Proportional-Integral-Derivative (PID)-controlled actuator was created, and sets of numerical data of inputs and outputs of the plant were generated. Then, a least-squares support-vector machine (LS-SVM) hysteresis model was trained inversely on the generated data sets of the numerical modeling. Afterwards, to examine the efficacy of the proposed method for real-world hydraulic actuators in the presence of experimental errors and noise, sets of experimental data were obtained from physical modeling at KNTU’s Structural and Earthquake Engineering Laboratory (KSEEL). The results indicate the high performance of the proposed model.

INTRODUCTION: The role of ovarian hormones and nitric oxide in learning and memory has been widely investigated. OBJECTIVE: The present study was carried out to evaluate the effect of the nitric oxide synthase (NOS) inhibitor, N (G)-nitro-L-arginine methyl ester (L-NAME), on the ability of estradiol to improve learning in OVX rats using the Morris water maze. METHODS: Forty rats were divided into five groups: (1) ovariectomized (OVX), (2) ovariectomized-estradiol (OVX-Est), (3) ovariectomized-L-NAME 10 (OVX-LN 10), (4) ovariectomized-L-NAME 50 (OVX-LN 50) and (5) ovariectomized-estradiol-L-NAME 50 (OVX-Est-LN 50). The animals in the OVX-Est group were treated with a weekly injection of estradiol valerate (2 mg/kg; i.m.). The OVX-LN 10 and OVX-LN 50 groups were treated with daily injections of 10 and 50 mg/kg L-NAME (i.p.), respectively. The animals in the OVX-Est-LN 50 group received a weekly injection of estradiol valerate and a daily injection of 50 mg/kg L-NAME. After 8 weeks, all animals were tested in the Morris water maze. RESULTS: The animals in the OVX-Est group had a significantly lower latency in the maze than the OVX group (p

Introduction & Objective: Many factors such as retirement, work disability, being isolated from the society, physical illness… affect the general health of the aged , one factor among many, is the role of psychological variables. The purpose of this study has been the investigation of the effect of positive and negative perfectionism and type D personality on general health of the aged. Materials & Methods: In this descriptive-correlational study, 80 subjects (47 males and 33 females) were selected through available sampling method among the aged in nursing homes in Hamadan and Malayer. Then the positive and negative perfectionism questionnaire of Terry- Short et al, that of type D personality and Goldberg and Hiller's general health questionnaire were administered to them. Results: Positive perfectionism (r=-0.30) and type D personality (r=0.32) had significant correlations with general health. Multiple regression analysis also revealed that positive perfectionism and type D could explain at least 49 percent of the variance of general health. The females’ mean was higher than that of males concerning the variables of depression-anxiety, speech inhibition and irritability and in positive perfectionism, general health and social function variables the males’ mean was higher than that of females. Conclusion: Creating optimistic attitudes and enhancing social functions, positive perfectionism may cause the mental disorder to be decreased in old age and type D personality however, positive perfectionism makes the aged apt to physical illness and mental disorder.

مقدمه: منابع محدود سبب عدم تعادل منابع بین جنبه‌های آموزشی و سلامتی در مدارس ایران گردیده است؛ استفاده از ابزاری مؤثر، سبب بهره گیری مناسب از منابع محدود موجود به منظور ارتقای سطح سلامت در كنار سطح آموزش در مدارس خواهد شد. یك سیستم مدیریت طراحی شده در زمینه‌ی سلامت در مدارس می‌تواند دارای یک ابزار مناسب ارزیابی با رویكرد رتبه‌بندی به منظور ایجاد انگیزه‌ی فزاینده در مدیران مدارس جهت ارتقای سطح سلامت در داخل مدارس باشد؛ بدیهی است این سیستم، که زیرساخت ابزار مورد نظر خواهد بود زمانی كارآمد و مؤثر می‌باشد كه همكاری‌های درون و بین بخشی به طور مناسبی برقرار گردد. روش‌ها: این پژوهش توسط یک چک لیست 81 پرسشی در 60 مدرسه در محدوده‌ی دانشگاه‌های علوم پزشكی در پنج استان ایران با همکاری مشترک وزارت بهداشت، درمان و آموزش پزشکی و وزارت آموزش و پرورش انجام شد. یافته‌ها: فقط 2/48 درصد از مدارس پایلوت دارای كلاس‌هایی با فضای مناسب حدود 4 متر مكعب به ازای هر دانش آموز در كلاس بودند. از طرفی تنها در 4/21 درصد مدارس از میز و صندلی‌های مناسب استفاده می‌شد. نیز 6/69 درصد از مدارس فاقد راه خروج اضطراری مناسب جهت استفاده در مواقع اضطراری بودند. پس از استقرار سیستم مدیریت سلامت (HSE) در مدارس پایلوت، ارتقای رتبه و ستاره‌های سلامت مشاهده گردید. نتیجه‌گیری: با توجه به محدودیت‌ها و مشکلات ایمنی و بهداشت در داخل مدارس، می‌توان با استقرار و نگهداری صحیح و اثربخش سیستم مدیریت سلامت (HSE) و رتبه بندی و اعطای ستاره به مدارس كشور، به یک زیرساخت مناسب و ابزار ارزیابی و کنترل دائمی مدارس از نظر مسائل مرتبط با ایمنی و بهداشت دست یافت. امید است با اجرای این طرح که با همکاری مشترک وزارتخانه‌های بهداشت، درمان و آموزش پزشکی و آموزش و پرورش در سطح ملی در حال اجراست، شاهد ارتقای مناسبی در سلامت مدارس (HSR) در كنار ایجاد عدالت اجتماعی و جلب مشاركت تمامی گروه‌های مرتبط، به خصوص دانش آموزان و اولیای آن‌ها باشیم. واژگان کلیدی: HSE، ایمنی، بهداشت، مدیریت، سیستم، مدارس
