Todays, parallel to growing in acceptance of functional products, various additives are used to improve the characteristics of functional food products. The coenzyme Q10 is an essential component for energy conversion and production of adenosine triphosphate (ATP) in the membranes of all body cells and organelles, especially the inner mitochondrial membrane is found. Coenzyme Q10 plays a vital ...

In this analysis, different tools were utilized in measuring the different parameters, which were DO, temperature, pH, and turbidity. For the measurement of each parameter (with exception of turbidity) we dipped the parameter-stick about half-way into the water while swirling it slowly. We continued doing so until the monitor displayed a stable measurement for us to record. Turbidity was slight...

Background and Objectives: Free living nematodes due to their active movement and resistance to chlorination don't remove in conventional water treatment processes thus can be entered to distribution systems and cause adverse health effects. UV irradiation can be used as a method of inactivating these organisms.Materials and Methods: This study is done to investigate the effect of ultraviolet l...

in general, estuaries may be classified variously according to inlet dynamics, geomorphology orwhether they are tide or river dominated or, on a combination of all three factors. in kwazulu-natal (kzn),south africa, the four recognised estuary types are temporary opened-closed estuaries (toces), permanently opened estuaries, estuarine lakes and river mouths. since physico-chemical parameters ar...

Turbidity is an important index to evaluate the water quality. Turbidity can reflect the effects of insoluble substances that contain bait and seston on water. Traditional methods of turbidity detection are complicated, they have low efficiency and poor reliability. To solve the turbidity detection problem in aquaculture, an intelligent optical turbidity sensor which is based on scattering theo...

bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
