phytoplankton and zooplankton concentrations in pishin reservoir are predicted employing a three-dimensional numerical model in this paper. modeling is performed using a numerical model based on mass transport equation. advection, diffusion and source/sink processes are considered as separate subroutines for predicting the concentrations of phytoplankton and zooplankton in the reservoir. finite...

background: the purpose of study was to evaluate and compare chemical quality of iranian bottled drinking water reported on manufacturer's labeling and standards. methods: this study was a cross-sectional descriptive study and done during july to december 2008. the bottled mineral water collected from shops randomly were analyzed for all parameters address on manufacturer's labeling and the res...

OBJECTIVE To evaluate the indigenous bacterial strains of drinking water from the most commercial water types including bottled and filtered water that are currently used in Saudi Arabia. METHODS Thirty randomly selected commercial brands of bottled water were purchased from Saudi local markets. Moreover, samples from tap water and filtered water were collected in sterilized glass bottles and...

Scientifically sound methods to rapidly measure fecal indicator bacteria are important to ensure safe water for drinking and recreational purposes. A total of 200 water samples obtained from the Three Gorges Reservoir during three successive one-year study periods (October 2009 to September 2012) were analyzed using multiple-tube fermentation (MTF) and most probable numbers combined with polyme...

The changes in yields and nutritive composition of whole crop wheat (Triticum aestivum L.) during maturation and effects of maturity stage and lactic acid bacteria (LAB) inoculants on the fermentation quality and aerobic stability were investigated under laboratory conditions. Whole crop wheat harvested at three maturation stages: flowering stage, milk stage and dough stage. Two strains of LAB ...

It is urgent to advance the discussion on the guidelines that Brazil should adopt to diversify energy sources in order to reduce dependency and promote the replacement of fossil fuels. This is one of the main ways to reduce the already deleterious negative impact that human activities are causing to the environment. This agenda includes the development of technologies for the expansion of sugar...

Tea colour determination during fermentation is a vital problem in the tea industries. The human experts have been traditionally measuring change of colour during fermentation by picking up some amount and observing the colour by eye approximation. Methods are also available for analyzing the formation of colour constituents during fermentation. Another method uses colorimeter for determining t...

Abstract :The main problem of processed vanilla bean is the poor quality. One of causal factor is the lack of appropriate equipment such as dryer, and fermentation equipment. The purpose of This research is to produce an equipment that able to perform both drying and fermenting the raw vanilla beans directly after harvesting that have a good performance. By using this machine it was expected th...

To investigate the ability of corn germ to withstand the fuel ethanol fermentation process without major damage to germ integrity and germ oil quality, five treatments were designed to explore degerming before fermentation (front-end) and after fermentation (tail-end), and the feasibility of breaking the kernel with minimum shear forces (wet-split). Germ from low-shear (wet-split) tail-end dege...
