background : ecological studies on mosquitoes are very important in vector control programs. there are a few studies about the ecology of mosquitoes in northern iran. this study was carried out to detect fauna and larval habitat characteristics of mosquitoes. methods : this study aimed to determine fauna and the ecology of mosquitoes in neka county, mazandaran province, northern iran from april...

background : the aim of this study was to obtain new data which would be valuable to develop programs for future planning of mosquito controls in in western iran. methods : larvae and adult collections were carried out from different habitats using standard dipping and animal baited trap methods during may, june and july 2012 in two provinces (kurdistan and kermanshah) in the west of iran. char...

macrobrachium rosenbergii lifecycle is unique so that the adults thrive in freshwater and larval development requires brackish water environments near to estuaries as close as possible to larval body isosmotic for minimum na/k-atpase activity and maximum atp storage. osmoregulation system at early larval stages is not formed and larval osmoregulation is mainly attributed to na/k-atpase activity...

background : considering the disadvantages of chemical insecticides, we aimed to evaluate vorticella parasites for control of mosquito larvae of anopheles stephensi and aedes aegypti at different larval stages. methods: vorticella sp infected mosquito larvae were crushed in the 0.85% saline and homogenized well to get vorti­cella in suspension. the effects of vorticella sp infections on larval ...

Conventional techniques for the determination of moisture content in grain often use small static samples to represent several tons of material, A more desirable alternative would be a method which utilizes continuous dynamic moisture measurement of the grain. The potential for making density-independent moisture content measurements in both static and flowing grain using microwave frequencies ...

We present a new tree-ring reconstruction of the Atlantic Multidecadal Oscillation (AMO) spanning 1568-2007 CE from northeast Asia. Comparison of the instrumental AMO index, an existing tree-ring based AMO reconstruction, and this new record show strongly similar annual to multidecadal patterns of variation over the last 440 years. Warm phases of the AMO are related to increases in growth of Sc...

The aim of this work was to study the effect of spray drying conditions on quality of coconut sugar powder and their characteristics. Effects of inlet air temperature (120°C, 150°C and 180°C) and maltodextrin concentrations (DE 9-12) at 10%, 20% and 30% (w/v) on physical properties of spray dried coconut sugar powder were investigated. Buchi mini spray dryer, model B-290, was used in this work....

Understanding the spatial and temporal variations of soil moisture is crucial for the land surface processes and their management. Accurate estimation of spatial and temporal variations of soil moisture is important for various hydrological studies also. Recently, remote sensing techniques have been used to estimate soil moisture. Estimation of soil moisture by remote sensing techniques provide...
