Study of soil properties like field capacity (F.C.) and permanent wilting point (P.W.P.) play important roles in study of soil moisture retention curve. Although these parameters can be measured directly, their measurement is difficult and expensive. Pedotransfer functions (PTFs) provide an alternative by estimating soil parameters from more readily available soil data. In this investigation, 7...

Background: A critical problem for hemodialysis patients are hepatitis infections. Some of the risk factors associated with HBV infection include blood transfusion, frequency, and duration of hemodialysis, and equipment contamination of infected patients. In fact, HCV infection through dialysis units has increased worldwide. Aims & Objectives: The aim of this study was to determine the prevalen...

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...

BACKGROUND A molecular survey was conducted to investigate the presence of pathogenic Borrelia persica species causing the tick borne relapsing fever (TBRF) in Takistan district Qazvin Province, western Iran. METHODS A number of 1021 soft ticks were collected from 31 villages including previously reported infected and none-infected TBRF cases and individually examined for the presence of B. p...

The objective of this study was to investigate fuzzy clustering analysis based on subtractive clustering algorithm for modeling of Soil Cation Exchange Capacity (CEC). In this work, seventy soil samples were collected from different horizons of 15 soil profiles located in the Ziaran region, Qazvin province, Iran. The data set was divided into two subsets. One for calibration (80% data) and seco...

BACKGROUND Gastric cancer is considered as the second most prevalent cancer in Iran. The present research sought to identify high risk clusters of gastric cancer with mapping using space-time scan statistics. MATERIALS AND METHODS The present research is of descriptive type. The required data were gathered from the registered cancer reports of Cancer Control Office in the Center for Non Commu...

BACKGROUND Arsenic (As), one of the most significant hazards in the environment affecting millions of people around the world is associated with several diseases including cancers, Diabetes Mellitus (DM) and Hypertension (Htn). Drinking water contaminated with inorganic arsenic (iAs) is the primary route of exposure. This study was conducted to determine the difference in the prevalence of DM a...

Background: Beta thalassemia is a common inherited disease, resulting from one or more of 200 different mutations in the beta-globin gene. Qazvin province has attracted migrations of several different populations due to industrialization during the past five decades. The aim of this study was to define the molecular spectrum of beta-thalassemia mutations in Qazvin province. Methods: Ethylen dia...

Objective: Today, addressing the issue of sustainability especially in agriculture has received more attention. Sustainability in the systems of Canola cultivation depends on many factors like ecological, social and economic dimensions and understanding these factors can result in formulation of policies and strategies for sustainable agricultural development. Methods: 8961 Canola farmers of Qa...
