Planktivorous fish directly suppress some prey species and indirectly affect species that interact with these prey (HRBACEK 1962, BROOKS & DODSON 1965, HALL et al. 1970, DRENNER et al. 1986). Visually feeding zooplanktivorous fish are size-selective predators, directly suppressing large zooplankton, and indirectly temporarily enhancing small zooplankton and phytoplankton (HURLBERT & MULLA 1981,...

Rich useful information can be obtained from the muscles and researchers can use such information in a wide class of clinical and engineering applications by measuring surface electromyography (EMG) signals (Merletti & Parker, 2004). Normally, EMG signals are acquired by surface electrodes that are placed on the skin superimposed on the targeted muscle. In order to use the EMG signal as a diagn...

A constitutively downregulated cytoprotective mechanism in response to oxidative stress and its constant companion, inflammation, may exist in clinical and experimental diabetes. The Nrf2 signaling pathway promotes the expression of a plethora of genes that regulate processes involved in protein stability, proteosome integrity, autophagy, senescence and protection against oxidative stress and i...

In this study, a set of nitrogen reduction strategies were modeled to evaluate the feasibility of improving water quality to meet total maximum daily loads (TMDLs) in two agricultural watersheds. For this purpose, a spatial-process model was calibrated and used to predict monthly nitrate losses (1994-96) from Sand and Bevens Creek watersheds located in south-central Minnesota. Statistical compa...

regarding sadr-ol-mote'allehin philosophical method, various opinions have been proposed from sadra researchers, each of which monitors a part of sadra’s philosophical method or it has paved a way which is different from sadra’s method and transcendent theosophy orators expositions and it is sometimes converse. his four methodological principles, i.e. purposeful combination of three mystic...

one of the prominent figures in epistemology from a moral-educative perspective is mulla sadra. this essay tries to analyze his ideas in a library-based method in order to find his educative methods. the key question is what educative methods are explicitly or implicitly mentioned in his epistemological ideas. he based his educative ideas upon his philosophical foundations specially the substan...

 In what follows, the author has dealt with the relation between the necessary being as an unchangeable Essence and His changeable and unchangeable attributes. Neither is the ascription of any changeable attribute impossible for God nor is the ascription of any kind of unchangeable attribute possible. As the change of genitive attributes does not demand the change in the Essence, it is possible...
