The phenomenon of changes which are expressed in increase benthic and periphytic primary production over pelagic production in the food web, had been named as process of “benthification” or “contouring”/contourization [1] which reflect an overall alteration of the aquatic ecosystem function [1-4]. Increased water transparency after Dreissena polymorpha Pallas 1771 invasion has been favor benthi...

Optical techniques are promising methods for measuring tissue temperature noninvasively due to the transparency of tissue to near infrared-light and the temperature dependent light-absorbing properties of endogenous absorbers, particularly water. Besides being noninvasive, the instruments are compact and portable, permitting bedside monitoring.

Objective: Pomegranate juice is a fruit native to Iran because of attractive color, smell and value of mineral water is popular fruits in the world. Pomegranate juice has more nutritional value is due to a combination of anthocyanins that reduce the risk of diseases such as cancer. Processes Feta membrane such as microfiltration 1 and 2 are used to clarify beer industry. Methods: The advantage ...

Economic transparency will lead to economic stability and corruption decline.

organizational transparency has been considered by many experts in the past two decades. in the previous studies more attention has been taken to disclosure of the information; and the relations between the concepts of organizational transparency, organizational culture and performance has not been considered in this article as set forth. therefore, current research has been studied the effect ...

the parameters used to determine the trophic state of a water body are: total phosphorus (tp),transparency (secchi disk depth) and chlorophyll a. however, these parameters show strong seasonalfluctuations which may hinder the estimation of trophic state. some authors have proposed that sediments be used as an additional tool to evaluate the trophic state of a water body. the aim of this study w...
