BACKGROUND Malaria is still a public health problem in the world. One of the main objectives of World Health organization is capacity building of authorities who are involved with malaria control activities. METHODS The first course was conducted in 1996 in Bandar Abbas Training center. The course was conducted jointly by the Ministry of Health and(More)
The resurgence of malaria has highlighted the need for training health professionals in malaria control planning. The course described here was organized jointly by the World Health Organization, the Ministry of Health and Medical Education and the School of Public Health in Iran. The first course was held in 1997 and the fifth WHO-approved course is now in(More)
Concerns about traditional chemical pesticides has led to increasing research into novel mosquito control methods. This study compared the effectiveness of 2 different types of polystyrene beads for control of mosquito larvae in south-east Islamic Republic of Iran. Simulated field trials were done in artificial pools and field trials were carried out in 2(More)
Natural Organic Matters (NOMs) are abundant in natural water resources and in many ways may affect the unit operations in water treatment. Although, NOMs are considered harmless but they have been recognized disinfection by-products precursors (DBP(s)) during the chlorination process. Formation of DBP(s) highly depends on the composition and concentration(More)
The objective of the study is surveying microbial quality of drinking water in Kashan rural areas and determining the rural population that using safe water in terms of microbial quality in second-half of 2008. In this cross-sectional study, microbial quality of water in all rural areas was determined in 3 stages based on 3 parameters as Total Coliforms,(More)
An aerated submerged fixed-film (ASFF) bioreactor was developed to treat an artificial wastewater based on crude oil. Bee-Cell 2000 was used as support media having porosity of 87% and a specific surface area of 650 m2 m(-3). The system was able to achieve 70.87-93.12% removal efficiencies of Chemical Oxygen Demand (COD) in the organic loading rate range of(More)
BACKGROUND In the past three decades, Tehran has experienced warmer summer so we need to determine heat-related mortality to establish appropriate public health activities during hot summers. The aim of the present study was to detect heat waves during the last decades and then determine excess mortality in immediate and lagged times. METHODS An(More)
Emissions of H2S from publicly owned treatment works is a serious problem, therefore collection and treatment of these emissions is essential. In this work, the performance of a bench scale activated sludge system used for the removal of H2S from foul air was investigated, and the effects of H2S concentration (5 to 50 ppm,) on COD reduction and biomass(More)
This study was done to investigate the reduction of anaerobic bacteria (Clostridium perfringens) by ultrasound irradiation technology (USI). C. perfringens is the most important of the sulfite-reducing clostridia and is normally present in human and animal feces. Clostridial spores survive longer than coliforms, Escherichia coli or enterococci, and are(More)
Natural Organic Matter (NOM), which can be broadly divided into two fractions of hydrophobic and hydrophilic, is abundant in natural water resources and in many ways may affect the unit operations in water treatment. It plays an important role in membrane fouling in the water treatment process. Fouling of membranes decreases the applicability of the(More)
