James B. Cotner Jr.,Robert G. Wetzel turbine (WT). Yet it is a crucial step in establishing the best aerodynamic achievement the WT can give. In this paper, the power coefficient of a WT utilizing different blade geometries are determined and compared using the BEMT method. The blade geometries are obtained from the proposed formulas

Results from scientific and commercial fishing activity though helping to clarify the probable abundance of fish, has done little to inform all concerned whether or not the EEZ declaration was a commercial bonan

Marion Köster,Preben Jensen,Lutz-Arend Meyer-Reil new polymers based on such oils represent an alternative approach to reducing the dependence on petrochemical derivatives (1–7). Triglyceride oils can be polymerized to form interpenetrating polymer networks, IPN’s. An IPN may be defined as a combination of two polymers in network form, at least on

Extracellular Enzymatic Interactions: Storage, Redistribution, and Interspecific Communication, element? This question is important because many scientists speak rather casually about endo- and exoenzymatic activity in relation to cellular metabolism. Obviously most of the enzymatic activity is intracellular, associated with biosynthetic reactions driven by energy liberated from the hydrolysis of ATP.

Phosphatase Activities in Lake Kinneret Phytoplankton,metabolic processes occurring in the cell. The inorganic forms of macronutrients such as P and N are generally the only compounds that can be directly taken up and utilized by algae although, it has been shown that both organo-P and organo-N compounds can be used as indirect sources of nutrients (Antia et al., 1975; Cembella et al., 1984a; 1984b).
