study of the ground water quality in hodeidah is an essential ingredient for a healthypopulation. in this research, study of drinking water samples for eight water sources wells in thequti field has been achieved. the purpose was to a certain the quality of water from thesesources, the physical properties such as ph, electrical conductivity (ec) and total dissolvedsolids (tds), showed the varia...

introduction: the need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. on the basis of environmental and economic considerations, these materials require treatment and management. anaerobic digestion and creation of biogas are the most effective methods of waste management. several parameters affect the anaerobic digestion of ...

The analysis of single molecule imaging experiments is complicated by the stochastic nature of single molecule events, by instrument noise and by the limited information which can be gathered about any individual molecule observed. Consequently, it is important to cross check experimental results using a model simulating single molecule dynamics (e.g. movements and binding events) in a virtual ...

Bimetallic nanoparticles are of interest due to their physical and chemical properties, which differ from their monometallic counterparts, and are dependent on size, composition and structure. Their unique chemical and physical properties make them useful in many optical, electronic and catalytic applications. In this perspective article we discuss segregation in bimetallic nanoparticles and hi...

R a Drying is a frequently used technological process that has found its use in almost every industry branch. It is a physical process where heat impact influences the lowering of material's moisture, without changing its chemical properties. Drying is one of the basic processes in production of ceramic products. Granulate is generated as a final output product after drying of the mixture of wa...

Nanometric objects attract huge interest due to their new and unexpected physical and chemical properties [1], which may allow the development of new technological devices. The study of these nano-objects is seriously limited by the fact that well-established conventional tools can not be easily applied in this size range. The development of new instruments and methodologies is necessary to all...
