Recent Electric Power Situation

Electric Power Generation with Reverse Electrodialysis

The computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. The program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area S = 1 m × 1 m = 1 m2, cell pair number N = 300 pairs). The stack operatingconditions are optimized. Seaw...

The Educational Situation Quality Model: Recent Advances

The purpose of this work was to present an educational model developed in recent years entitled the "The Educational Situation Quality Model" (MOCSE, acronym in Spanish). MOCSE can be defined as an instructional model that simultaneously considers the teaching-learning process, where motivation plays a central role. It explains the functioning of an educational setting by organizing and relatin...

The recent malaria situation in Chittagong, Bangladesh.

This is a retrospective study on 7,005 cases of malaria treated in a base hospital during the period 1998 to 2001. The aim of the study is to analyze the patterns, complications and mortality rates of malaria and its response to standard anti-malarial drugs. Diagnosis of malaria was made from identification of parasites on Giemsa stained thick and thin blood slides among the febrile cases and t...

Electric Power Quality Measurement

The proliferation of non-linear and time-variant loads is causing a number of disturbances on the electric network, from a more and more significant distortion of both currents and voltages, to transient disturbances on the supply voltage. In this respect the electric network behaves as an "healthy carrier" of disturbances, so that a disturbance generated by one customer can be distributed to o...
