Irrigation with electric pumps is cheaper than diesel in West Bengal where electricity and are unsubsidised, pump owners typically irrigate their winter rice crop often sell water to farmers who do not own pumps. Using purposefully selected primary data, we examine whether electric-pump have greater access production during the monsoon seasons compared diesel-pump buyers. We also pump-owners pr...

humanism and socio-constructivism have entailed drastic developments in education including that of foreign/second language. incorporating teachers and learners in all areas of education including materials development and evaluation, focusing four-pairs of binoculars on evaluating efl materials can be taken amongst the outcomes of this trend.  this study is a report of an evaluation of the esp...

This paper presents a multiobjective fuzzy genetic algorithm optimization approach to design the submersible induction motor with two objective functions: the full load torque and the manufacturing cost. A multiobjective fuzzy optimization problem is formulated and solved using a genetic algorithm. The optimally designed motor is compared with an industrial motor having the same ratings. The re...

The increased popularity of centrifugal pumps is due to largely to the comparatively recent development of high speed electric motors, steam turbines and internal combustion engines.To improve the performance of centrifugal pumps by studying the key components like impeller to find the optimum conditions using software. A literature review and lots of development in Computational CFD motivated ...

An ion motive ATPase is a membrane protein that pumps ions across the membrane at the expense of the chemical energy of adenosine triphosphate (ATP) hydrolysis. Here we describe how an external electric field, by inducing transitions between several protein configurations, can also power this pump. The underlying mechanism may be very similar to that of a recently constructed adiabatic electron...

The technical task of creating new designs submersible vane pumps is to maintain stable operating parameters and increase the productivity pumping station with periodic regeneration sediment removal. well contains an outer chamber inner chamber, in which a unit installed, pipelines are connected lower upper pools. In structure under study, parts chambers equipped sealed head, part stopper. side...

This report describes a design optimization model for an automotive water (coolant) pump driven by a DC electric motor. It is intended for use as an example problem for multidisciplinary design optimization (MDO) methods, and consists of several interacting analysis functions. These analysis functions are based on sets explicit algebraic equations, making this model easily reproduced for use in...
