the main purpose of the study is determination of the pollutants hazard potential as well as environmental vulnerability of qarah su river. first the most significant pollutant sources in the qarah su river watershed were identified and then accordingly the pollution hazard potential rate was calculated in universal ranking system model setting. then, by generalizing the algebraic sum of the re...

the efficiency of three statistical models, ahp surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in chehel-chai watershed in golestan province, iran. in current study the hazard map was prepared according to the top model of landslide hazard map. chehel-chai watershed is located as one of go...

In this paper we present CHAI, a set of haptic/graphics C++ libraries that were developed in the last years by a varied group of researchers. The CHAI libraries allow both high level and low level programming of haptic applications. Users that are not interested in implementation details can easily build visual-haptic scenes using a large set of pre-implemented algorithms. However, differently ...

BACKGROUND Depression is a common mental disorder. Chai Hu Shu Gan San, a traditional Chinese medicine, is used to treat depression empirically. We present a systematic review and meta-analysis of the therapeutic efficacy and safety of Chai Hu Shu Gan San in treating depression. METHODS Several databases, including PubMed, China National Knowledge Internet, Wanfang, Chongqing VIP, and the Coc...

introduction: time series models are generally categorized as a data-driven method or mathematically-based method. these models are known as one of the most important tools in modeling and forecasting of hydrological processes, which are used to design and scientific management of water resources projects. on the other hand, a better understanding of the river flow process is vital for appropri...

Water quality of seasonal water rivers is on a quick decline due to various human activities arising as result urbanization and population growth. This study assessed the Khassa-Chai river in Kirkuk during two seasons: winter summer (wet dry). Thirty-seven samples were collected from eight monitoring observation points along October 2019 March 2020. analyzed for parameters such temperature, pH,...

Fish are among the main target groups when conducting biomonitoring and ecological assessment of aquatic environments. Environmental DNA (eDNA) metabarcoding provides a unique opportunity to enhance throughput, precision, standardization. However, few fish monitoring studies based on eDNA have been conducted at basin scale. Taking Dianchi Lake three inflowing rivers (Panlong River, Baoxiang Cha...
