Development of 12V-30W Solar Cell by Local Materials of Rural Bangladesh
Abstract: Sustainable social and economic development depends on adequate power generation capacity of a country. In order to increase the power generation by fuel diversification, the development of renewable energy is one of the important strategies. Bangladesh is one of the densely populated countries which do not have sufficient supply of energy. The present crisis in power supply hints at the troublesome time to come ahead. To cope with the exponential …

The Riverine Pollution-A Critical Review to Study the Water Quality and Pollution Load of Some Major Rivers of India
Abstract: Every life form on earth need water, which is one of the basic resources.. India is a country of rivers and some of the rivers are considered sacred and are associated with religious importance. However, the rapid increase in population, urbanization, and increased anthropogenic invasions has resulted in the deterioration of the water quality. Rivers are always seen as the easiest sinks to dispose of all kinds of wastes; hence …

Thermal Adsorption Processing of Hydrocarbon Residues
Abstract: The raw materials of secondary catalytic processes must be pre-refined. Among these refining processes are the deasphalting and demetallization including their thermo-adsorption (or thermo-contact adsorption) variety. In oil processing, four main processes of thermo-adsorption refining of hydrocarbon residues are used—Asphalt Residual Treating- residues deasphaltizing (ART), Discriminatory Destructive Distillation (3D), developed in the US; Adsorption-Contact Treatment (ACT) and Express Thermo-Contact Cracking (ETCC), developed in Russia. ART and ACT are processes with …

Flood Resistant Houses
Abstract: Unusual high stage of river is called flood. In flood, the water level rises to an extent in which water starts spilling over the bank and spreading to the flood plains. The frequency and intensity of floods has intensified in the country over the years primarily due to encroachment of flood plains because of obvious advantages of water supply and irrigation. Flood causes extensive damage to infrastructure, the economy and …

TORQUE RIPPLE MINIMIZATION OF PV BASED SRM DRIVE
Abstract: The switched reluctance motor drive is the recent choice for industrial applications due to its unique features like double salient pole motor without winding, permanent magnet and commutator in rotor. Solar photovoltaic based water pumping system using AC and DC motor is common but SRM drive is more favourable in terms of cost, reliability, robustness in nature. The primary drawback of SRM drive is higher torque ripple which makes heavy …
