Small Hydro-power Plants (SHP) are an important source of electricity in many countries. However, little is known about SHP in Kenya. This paper reviews the status, challenges in implementation of SHP and prospects for future development of SHP in Kenya. The paper shows that SHP has not yet fully utilized the available hydro-power potential. The challenges associated with SHP development should...

BACKGROUND AND OBJECTIVES Hydro-Jet technology has long been used for cutting various materials like metal and wood in the industrial field. In the medical field, this technology has been applied successfully for selective cutting of the parenchyma of the liver. However, to our knowledge, no data exist on the use of the Hydro-Jet technique for laparoscopic cholecystectomy. The purpose of this s...

The three renewable energy technologies discussed in this paper are based on water, but differ markedly in terms of the size of the available potential resource, the maturity of the associated conversion technologies, the extent to which they have been exploited to date, and the current research effort being devoted to their future development. Hydro-electricity and tidal power are both very ma...

The title compound, C(3)H(10)NO(3)P, crystallizes in its zwitterionic form, H(3)N(+)CH(C(2)H(5))PO(O(-))(OH), with the asymmetric unit being composed by two of such entities (Z' = 2). The crystal packing leads to a sequence of hydro-phobic and hydro-philic layers. While the hydro-phobic layer comprises the aliphatic substituent groups, the hydro-philic one is held together by a series of strong...

PURPOSE Plant-derivate therapeutic agents can perform cancer chemotherapeutic activity through triggering apoptotic cell death. Our aim was to investigate the cytotoxic effects, induction of apoptosis, and the mechanism of cell death of Iranian orthodox black tea extracts (BTEs) and hydro methanolic purified fractions (40, 60, 80 and 100%) in KB cells (oral squamous cell carcinoma). METHODS I...

The short term hydrothermal scheduling (STHTS) is a daily planning proposition in power system operation. The main purpose of hydro thermal generation scheduling is to minimize the overall operation cost and to satisfy the given constraints by scheduling optimally the power outputs of all hydro and thermal units under study periods, given electrical load and limited water resource. This paper p...

Background Hydro-distillation (HD) method is a traditional technique which is used in most industrial companies. Microwave-assisted Hydro-distillation (MAHD) is an advanced HD technique utilizing a microwave oven in the extraction process. Methods In this research, MAHD of essential oils from the aerial parts (leaves) of rosemary (Rosmarinus officinalis L.) was studied and the results were co...

Background: Although hydro-alcoholic extracts of Anethum graveolens L. had Anticonvulsants effect on PTZ-induced kindling seizure behavior, but on the amygdala kindling in rats induced seizure has not been investigated. Objective: In this study, we evaluated the chronic effects of hydro-alcoholic extracts of Anethum graveolens L. on seizures using electrical amygdala kindling model. Methods: ...

Recent growth in the renewable energy industry has increased government support for alternative energy. In the United States, hydropower is the largest source of renewable energy and also one of the most efficient. Currently, there are 30,000 megawatts of potential energy capacity through smalland micro-hydro projects throughout the United States. Increased development of micro-hydro could doub...
