1Egg consumption and risk of non-alcoholic fatty liver disease显示文摘AIM To evaluate the association between egg consumption and risk of non-alcoholic fatty liver disease(NAFLD) development.METHODS This case-control study was conducted on individuals who were referred to two hepatology clinics in Tehran, Iran in 2015. The study included 169 patients with NAFLD and 782 controls. Egg consumption was estimated using a validated food frequency questionnaire. The participants were categorized according to the frequency of their egg consumption during the previous year: Less than two eggs per week, two to three eggs per week, and four or more eggs per week.RESULTS In the crude model, participants who consumed 2 to 3 eggs per week, were 3.56 times more likely to have NAFLD in comparison to those who consumed less than 2 eggs per week(OR: 3.56; 95%CI: 2.35-5.31). Adjustment for known risk factors of NAFLD strengthenedthis significant association so that individuals have consumed two to three eggs per week had 3.71 times higher risk of NAFLD than those who have eaten less than two eggs per week(OR: 3.71; 95%CI: 1.91, 7.75). CONCLUSION Our data indicate that higher egg consumption in common amount of usage is associated with higher risk of NAFLD.Zeinab Mokhtari Hossein Poustchi Tannaz Eslamparast Azita Hekmatdoost 2017World Journal of Hepatology2017,9,10:3
2Design and fabrication of a large-scale oedometer显示文摘The most common apparatus used to investigate the load-deformation parameters of homogeneous fine-grained soils is a Casagrande-type oedometer. A typical Casagrande oedometer cell has an internal diameter of 76 mm and a height of 19 mm.However, the dimensions of this kind of apparatus do not meet the requirements of some civil engineering applications like studying load-deformation characteristics of specimens with large-diameter particles such as granular materials or municipal solid waste materials. Therefore, it is decided to design and develop a large-scale oedometer with an internal diameter of 490 mm. The new apparatus provides the possibility to evaluate the load-deformation characteristics of soil specimens with different diameter to height ratios. The designed apparatus is able to measure the coefficient of lateral earth pressure at rest. The details and capabilities of the developed oedometer are provided and discussed. To study the performance and efficiency, a number of consolidation tests were performed on Firoozkoh No. 161 sand using the newly developed large scale oedometer made and also the 50 mm diameter Casagrande oedometer. Benchmark test results show that measured consolidation parameters by large scale oedometer are comparable to values measured by Casagrande type oedometer.Maryam Mokhtari Nader Shariatmadari Ali Akbar Heshmati R Hossein Salehzadeh 2015Journal of Central South University2015,22,3:1

12一种永磁同步风力发电机在电网故障下达到最大限度电网支持的通用分析方法(英文)显示文摘提出了一种基于永磁同步发电机的风力发电机故障共线策略。该策略不考虑电网故障类型,对参考电流信号进行了解析计算,并利用整个系统的容量来注入电网编码所需的无功电流,传输最大可能的有功功率以支持电网频率,避免发电损耗。所有这些都是通过考虑电网侧变换器的相电流限制而实现的。该策略适用于不同国家的电网编码,在电网不平衡的情况下,防止了脉动有功功率的注入。模型预测电流控制器用于处理快速瞬变。在故障期间,储能系统保持DC连接电压,显著消除电压波动。本文提出了一种基于永磁同步电机的风电机组故障共乘策略,忽略了故障特性;其次,在电网故障的情况下达到最大可能的电网支持,同时避免过电流;第三,大幅度降低储能系统的规模和额定功率。通过MATLAB/SIMULINK仿真,验证了该方法的可行性和竞争力,并对整个控制系统的效率进行了仿真。Farid Atash BAHAR Ali AJAMI Hossein MOKHTARI Hossein HOJABRI 2019Journal of Central South University2019,26,10:0
13Estimating oak forest parameters in the western mountains of Iran using satellite-based vegetation indices显示文摘Remote sensing is an important tool for studying and modeling forest stands.Vegetation indices obtained from Landsat-8 remotely sensed data were used to estimate the forest parameters in the western mountains of Iran.Thirtyfour sample points were selected on the map of Bayangan County,Kermanshah province,Iran.At each point,a cluster of five rectangular plots of 8100 m2 and 200 m apart was established.Some clusters were primarily sampled to determine the variance of the forest parameters.The coefficient of variation was used as a criterion for sample allocation.Stand density,canopy cover and basal area per hectare were calculated for each plot.Vegetation indices were extracted fromthe Landsat-8 images for each plot.Simple linear and nonlinear regressions were conducted to develop the models.The models were validated using an independent data set.Stability of model parameters was statistically evaluated.The results showed that Normalized difference vegetation index(NDVI)and Transformed normalized difference vegetation index(TNDVI)followed by Simple ratio vegetation index(SRVI)were the best predictors,explaining up to 91%of the variations with high precision.For NDVI,Soil adjusted vegetation index 2(SAVI2)and SRVI,the cubic model was more appropriate than the linear model for predicting the forest parameters.For this model,the R-square value increased while NRMSE decreased significantly.For Infrared percentage vegetation index(IPVI),the quadratic model was better,but,for other vegetation indices,nonlinear models were not superior to linear ones.Finally,it can be concluded that Landsat-8 imagery is suitable for predicting forest parameters in the oak forests of western Iran.Of course,large plots must be selected,and pre-classification is necessary to gain accurate and precise estimations.Adel Nouri Bahman Kiani Mohammad Hossein Hakimi Mohammad Hossein Mokhtari 2020Journal of Forestry Research2020,31,2:0
