Background & Aims: Immunodeficiency virus (HIV) may lead to acquired immunodeficiency syndrome (AIDS) in human. Parasites are one of the most important causes of infectious diseases in patients with AIDS. The prevalence of these parasites varies based on the condition of host’s immune system and the stage of disease (HIV/AIDS). To compare the prevalence of opportunistic intestinal parasites a c...

Hydrological processes and their spatial distribution directly are relevant to climate, topography, geology, and land use in the watershed. Therefore, use of a model whit integrity and high performance for simulating the process in deferent watersheds is very important. In this study was assessment performance of semi-distributed SWAT model in simulating hydrology processes in three watersheds ...

every year, a considerable portion of the national budget specifies to reconstruct the properties which have been destroyed during natural disasters in iran. recognition of vulnerable sites to natural disasters can reduce the probable damages. the most important point in designing railway tracks is to join stations in the least possible time. so, the railway track is meant to cross lots of vall...

thirteen environmental elements were distinguished in the livers of various species of fish thathave been sampled from 15 sites in a restricted area of the khorramabad river basin in lorestan province(west of iran). sites sampled represented agricultural, mining, mixed, and urban/recreation land uses andbackground conditions. lithium and silver were not detected at any of the sites. the minimum...

results overall, the prevalence of unwanted pregnancies was 32.3%. the performance of the models based on the area under the roc curve as the indicator was as follows: artificial neural networks (0.741), decision tree (0.731), and logistic regression (0.712). the highest sensitivity level belonged to the decision tree (73.5%), and the highest specificity level belonged to the artificial neural ...

Introduction Radioactive materials naturally exist in the world. Indeed, approximately 82% of human-absorbed radiation doses, which are out of human control, arise from natural sources of radiation including cosmic, terrestrial, and exposure through inhalation or ingestion. Thus, the aim of the present study was to estimate health risk, as well as the effective and organ doses from naturally oc...
