Flat plate-type solar water distillation (FPSWD) is having importance for providing hot water and drinking water simultaneously to households in rural areas or small community/hotels. It utilizes solar radiation to heat the water, produce fresh water out of the saline or brackish water, and also produce hot water. The paper is focused on field performance of inclined FPSWD for domestic and comm...

Bryozoans are aquatic invertebrates that inhabit all types of aquatic ecosystems. They are small animals that form large colonies by asexual budding. Colonies can reach the size of several tens of centimeters, while individual units within a colony are the size of a few millimeters. Each individual within a colony works as a separate zooid and is genetically identical to each other individual w...

New criteria (full physiological value and preservation of the properties of drinking water) are scientifically substantiated. Also discussed are indices (minimal admissible and optimal levels of basic water mineralization and calcium content, standards of microelements such as boron and bromine content, content of individual groups of microorganisms, water temperature) for evaluating the quali...

The performance of commercial composite reverse osmosis membranes has been continuously improving, since its introduction in the late seventies. An additional significant improvement of membrane performance has been achieved at the beginning of 1995, when new composite polyamide brackish water RO membrane technology has been introduced. The new membrane material is characterized by a very high ...

Disposal of concentrate from brackish water desalination plants by deep well injection into oil and gas fields is an attractive option in Texas. Underpressured depleted oil and gas reservoirs cover large areas of the state. Six areas were selected from across Texas for detailed analysis. These sites were characterized by abundant brackish groundwater, a projected shortage of freshwater, deplete...

The relative importance of natural selection and genetic drift in determining patterns of phenotypic diversity observed in nature is still unclear. The natterjack toad (Bufo calamita) is one of a few amphibian species capable of breeding in saline ponds, even though water salinity represents a considerable stress for them. Results from two common-garden experiments showed a pattern of geographi...

Metagenomics refers to the analysis of DNA from a whole community. Metagenomic sequencing of environmental DNA has greatly improved our knowledge of the identity and function of microorganisms in aquatic, terrestrial, and human biomes. Although open oceans have been the primary focus of studies on aquatic microbes, coastal and brackish ecosystems are now being surveyed. Here, we review so far p...

Background & Aims of the Study:  Recently membranes have been widely used in Mena region especially Iran,  due to purify the brackish water and solved the water scarcity  .Qom province is located in desert like area of Iran and faced to water shortage .The aim of this study is evaluation of the best method of membrane process in the ground water wells of Qom province, Iran, in 2016. Materials ...

Divergent selection pressures induced by different environmental conditions typically lead to variation in life history, behavior, and morphology. When populations are locally adapted to their current environment, selection may limit movement into novel sites, leading to neutral and adaptive genetic divergence in allopatric populations. Subsequently, divergence can be reinforced by development ...
