One of the main aims of water resource planners and managers is to estimate and predict the parameters of groundwater quality so that they can make managerial decisions. In this regard, there have many models developed, proposing better management in order to maintain water quality. Most of these models require input parameters that are either hardly available or time-consuming and expensive to...

today, with the advanced statistical techniques and neural networks, predictive models of distribution have been rapidly developed in ecology. purpose of this research is to predict and map the distribution of tetranychus urticae koch (acari: tetranychidae) using mlp neural networks combined with genetic algorithm in surface of farm. population data of pest was obtained in 2016 by sampling in 1...

in order to study the effects of planting systems on quantitative and qualitative characteristics of some onion genotypes, an experiment was conducted in a split plot arrangement in randomized complete block design with three replications in behbahan agriculture research station for two years (2012-2014). in this study two planting systems: onion set and transplant were assigned to main plots a...

this study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the coniacian–santonian sediments of tange-bulfaris section. five assemblage zones have been recognized by distribution of the foraminifera in the study area. assemblage zone 1(chara ostracods zone) is coniacian in age and occurs in the lower part of the succession. assembla...

background and aims: medicinal plants are a valuable resource for flavonoids extraction. prosopis fracta is one of the plants with medicinal properties. prosopis fracta was found in abundance in southern regions in iran. coersetin is medicinal substance found in the fruit of this plant. quercetin is used in treatment of cancer and viral infections. this study was conducted to determine the quer...
