District of Jiroft is situated in south-east of Iran which is one of the malarious regions. Anopheles stephensi is considered as one of the main malaria vector in this region. Ecology of this species was studied in the area to understand its vector behavior for implementation of effective vector control measures. Different methods like total catch, pit shelter, night bite collection on human an...

Hormozgan Province is located in the south of Iran bordering the Persian Gulf. In this area, malaria is still considered a major health problem. In the province, eleven species of Anopheles were identified: An. pulcherrimus, An. sergenti, An. apoci, An. multicolor, An. subpictus, An. turkhudi, An. fluviatilis, An. stephensi, An. d'thali, An. superpictus, and An. culicifacies, among which only t...

Historical data were used to reconstruct channel change in the Middle Fork John Day River, a tributary of the Columbia River. Human impacts on the channel from the 1800s to present include: beaver trapping, early alluvial gold mining, dredge mining, livestock grazing, haying and irrigation, railroad-building, road-building, and placing of bank stabilization structures. 1881 land survey records,...

A populational study of the compatibility between Schistosoma haematobium and its potential vectors has been carried out in the Niger, confronting samples of S. haematobium populations from three epidemiologic foci with Bulinus populations originating from the same focus (sympatric infection) and with Bulinus populations from other foci (allopatric infections). The three transmission foci selec...

Anopheles arabiensis Patton (Diptera: Culicidae) is considered the most efficient malaria vector in eastern Sudan. This study aims to characterize the breeding sites of An. arabiensis throughout the year in and around Kassala town, eastern Sudan. Diverse larval habitat types were visited and characterized based on the habitat type and chemical composition. Mosquito larvae were found in many div...

Two potential measures for increasing water use efficiency in a municipal sports center were evaluated: (1) the reuse of originating from showers flushing toilets indoor football court building; and (2) swimming pool filter backwashing irrigation. In building total annual consumption is around 3,500.5 m3 approximately 1,785.26 m3. Therefore, greywater generated can be reused toilet flushing, wh...

background: trihalomethanes are toxic and dangerous substances that are formed in the presence of organic materials when water is chlorinated for disinfection. the iranian national standard, world health organization, european :union:, u.s. environmental protection agency and international agency for research in cancer standards have established a maximum contaminant level for trihalomethanes f...
