Microbiological water quality monitoring in Niassa province, Northern Mozambique, shows groundwater is not, in general, grossly contaminated though contamination levels are strongly linked to season and to risks observable at the wellhead, especially risks dealing with wellhead hygiene and maintenance. Diarrhea incidence, in general, is greatest in the rainy season suggesting poor wellhead prot...

In this paper, the solubility of CO2 in AMP solution have been measured at temperature range of ( 293, 303 ,313,323) K.The amine concentration ranges studied are (2.0, 2.8, and 3.4) M. A solubility apparatus was used to measure the solubility of CO2 in AMP solution on samples of flue gases from Thermal and Central Power Plants of Esfahan Steel Company. The modified Kent Eisenberg model was used...

Drought is a major problematic phenomenon mostly for semi-arid areas of Iran. During drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. Therefore, the assessment of drought effects on plant covers is the most important issue. This research was conducted in 2015 using the extracted vegetation indices from Moderate Resolution Ima...

the standardized precipitation index (spi) has become a popular measure of drought across the globe. in this study, standardized precipitation index (spi) was used in annual period of time to survey on drought. also, in order to zonation frequency of drought, geographic information system (gis) software and kriging method used for extracting dry areas. the zoning maps show most severe drought i...

the herd consisted of 25 captive esfahan mouflons and theiroffspring. the mouflons were wild and originated from theirnatural habitat in esfahan province. they had been kept in smallenclosures with rough concrete floors. the diet consisted ofalfalfa hay, corn silage, and a commercial concentrate. themouflons showed severe claw overgrowth and detectablesubclinical form of laminitis such as sole ...

Modeling land allocation for different land uses at regional level is a multi-dimensional problem, as it is influenced by spatial, temporal and dynamics of environmental and socio-economic factors in the complex process of land use change. It is therefore a challenge to develop a proper model that can handle these complexities. In this context, a new model has been conceptualized and developed....

Modeling the dependency between stock market returns is a difficult task when returns follow a complicated dynamics. It is not easy to specify the multivariate distribution relating two or more return series. In this paper, a methodology based on fitting ARIMA, GARCH and ARMA-GARCH models and copula functions is applied. In such methodology, the dependency parameter can easily be rendered condi...
