Due to complex relations present in hydropower markets, and having in mind the specific role of hydropower in common electricity generation and transmission grid systems, it is impossible to identify a unified approach to hydropower plant management. The ever-changing market behavior also presents a problem for unification of methodologies and all this imposes the interpretation of hydropower p...
In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository.

with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
The problem of hydropower plant profit maximization includes simultaneous programming of optimal utilization of water resources and participation in the power market. The present research was performed on a chain of hydropower plants within the Karoon river basin in Khuzestan Province (Iran) (i.e. Karoon 3, Karoon 1, and Masjid Soleyman hydropower plants). In this research nonlinear programmi...
In this paper we discuss how three different public policy measures affect water storage controlled by hydropower producing firms. In particular we discuss measures to promote competition, increase transmission capacity and rationing. The analysis is conducted within the framework of an oligopoly model where 2 hydro producing firms engage in dynamic Bertrand competition. We extend this model to...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Hydropower accounts for about 16 % of the world’s electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity – t...
increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...
due to lack of knowledge management system in the organization of technical and vocational university of iran (tvuni) and losing good employees because of retirement and substitution causes huge amount of costs to replace the similar expertise. there is no any suitable system in the tvuni to store, to document, and to distribute knowledge. based on the university’s features such as it has diffe...
Climate change remains a threat to water resources projects in southern Africa where impacts resulting from changes in climate are projected to be negative and worse than in most other regions of the world. This work presents an assessment of the impacts of climate change on water resources and hydropower production potential in the Zambezi River Basin. Future climate scenarios projected throug...
