Groundwater ecosystems remain poorly understood yet may provide ecosystem services, make a unique contribution to biodiversity and contain useful bio-indicators of water quality. Little is known about ecosystem variability, the distribution of invertebrates within aquifers, or how representative boreholes are of aquifers. We addressed these issues using borehole imaging and single borehole dilu...

A quantitative microbial risk assessment (QMRA) was performed at four managed aquifer recharge (MAR) sites (Australia, South Africa, Belgium, Mexico) where reclaimed wastewater and stormwater is recycled via aquifers for drinking water supplies, using the same risk-based approach that is used for public water supplies. For each of the sites, the aquifer treatment barrier was assessed for its lo...

A large fraction of the fresh water available for human use is stored in groundwater aquifers. Since human activities such as mining, agriculture, industry and urbanisation often result in incursion of various pollutants to groundwater, routine monitoring of water quality is an indispensable component of judicious aquifer management. Unfortunately, groundwater pollution monitoring is expensive ...

this paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from mighan playa aquifer. cluster analysis classified samples into four clusters(a, b, c and d) according to their dominant chemical composition: cluster a (dominant comp...

Methods: This quasi-experimental was done in Arak University Medical Sciences hospitals, Arak, Iran. Samples were 44 patients with failure, studied two groups. Twenty-two received education through content developed by researchers a trained educa...

BACKGROUND Toxoplasma gondii is an intracellular protozoan parasite that infects human and animals. Toxoplasma parasites are isolated from different parts of animals even from semen but there are little information about the effect of toxoplasmosis on fertility in animals and humans. In present study, the effect of chronic toxoplasmosis on serum levels of testosterone in men was studied. METH...

BACKGROUND The aim of this study was to evaluate the content of mercury (Hg), arsenic (As), nickel (Ni) and tin (Sn) in raw cow's milk of traditional and industrial sites from 8 different sites in Arak City, Markazi Province, Iran. METHODS In this cross sectional study, a total of 32 samples were collected from sub-cities of Arak, Iran via subjective sampling method. Both industrial and tradi...

OBJECTIVE To evaluate the viral antibodies in new Iranian multiple sclerosis (MS) patients. METHODS In a cross-sectional study, sera from 61 MS patients and 60 healthy individuals were collected from January 2009 to March 2010 in the Immunology Department of Arak University of Medical Sciences, Arak, Iran, and examined for the presence of the anti-Epstein-Barr virus (EBV), human herpes virus ...

Hydatidosis is one of the most important parasitic diseases worldwide, and it is caused by the larval stage of Echinococcus granulosus. This disease is endemic in Iran and can cause large losses of life and property. A few studies have been done in this area in Arak city, Iran. This study aims to investigate the prevalence of medical and surgical treatment of patients with hydatid cyst in hospi...
