ISBN: 9783843356770 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The river Sitalakhya, one of the most important and prominent rivers in the flood plain region of Bangladesh is located in Narayanganj, an industrial zone of the country. The present deterioration of its water quality is not related to the water itself but also to the danger of diffusion of toxic substances into the ecosystem. Again the general and poor people of the country are lacking access of safe water for drinking as well as for their domestic use. The present situation is enough to take prescience for any educated person to foresee problems in the future for water bodies with all its...

Solar Hot Water Heating Systems
ISBN: 9783843356503 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The current state of our environment calls for an energy revolution. To combat the threats of global warming and growing pollution due to fossil fuels, the United States must shift away from depleting non- renewable energy sources towards a more stable alternative. The most viable alternative at this time is solar energy. This paper observes the steps needed for a speedy transition towards this clean and renewable energy source. The first section of this thesis outlines the possible governmental and social incentives needed to power this revolution. While the second portion addresses...

Modeling the hydro-meteorological time series
ISBN: 9783843365789 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The importance of finding a well fitted model for hydro-meteorological time series cannot be denied, the main gain of a successful approach being the possibility to explain the past and to provide informed insight for the future. Therefore, we tried to present here some techniques that can be used to build a mathematical model for time series (particularly for hydro-meteorological ones), starting from statistical tests of data analysis, passing to the empirical models, nonparametric techniques, ARIMA models and heuristic methods. Since our intention was to write a book easy to read, the...

Management of Feacal Slude in Low-income Countries: A Case of Ghana
ISBN: 9783843369787 / Angielski / Miękka / 376 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Effective excreta or faecal sludge management towards emptying, transport and disposal from urban on-plot latrines in low-income countries is critical for the sustainability of urban sanitation. However literature mentions lack of effective management for these in low-income countries. The current management practice is fragmented and improper leading to poor health and environmental problems. No substantive information is found relating to how the removed excreta from the latrines is transported for disposal. Also information on household finances and perceptions about emptying and transport...

Why What Works, Doesn't
ISBN: 9783843369749 / Angielski / Miękka / 60 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Many environmental problems have to do with energy use, it is therefore very surprising that profitable opportunities to reduce energy consumption, awarding both economical and environmental benefits, are not more widely implemented. This work lists examples of such technological opportunities, discusses the barriers to their adoption, and suggests policy solutions to overcome these barriers. The focus group for this research are municipalities as energy users, mainly in Israel and Sweden. The author concludes that increase use of environmental technologies is possible, many times with...

The use of Iraqi Clay Minerals (ICM) for the removal of hazardous organic and inorganic water pollutants is investigated using synthetic aqueous solutions. Four locally available clays namely, bentonite, kaolinite, porcelainite and diatomite, were purified, sampled and characterized by XRD, XRF, FTIR spectroscopy and SEM. The surface areas were determined using BET and methylene blue adsorption method. Cation exchange capacity (CEC) was estimated using the method of adsorbing an ethylenediamine complex of copper method and the modifier loading was calculated from the total carbon analysis....

The Heat Pumps
ISBN: 9783843369855 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The heat pump is a machine that draws heat from one place to another investment of external work. Usually it is from the colder to warmer place. Heating heat pump is a device that uses non-traditional sources of energy for central heating and hot water. The basic view of heat pumps is that the planets global temperature regime is directly added heat from the combustion of any fuel. Indirectly, there is a certain amount of heat in power plants - the production of electricity consumed for heat pump operation. In the first part of my project I explain the heat pump principles. Then...

ISBN: 9783843376105 / Angielski / Miękka / 128 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Until 20 years ago, an important part of Timi County was affected by humidity excess of different types. As a consequence were designed and installed many drainage arrangements which worked intensive, during the drought periods being created perfect conditions for most of the crops. Between 1990 and 2000 the situation has changed. The climatic changes together with the significant decrease of water table (result of intensive drainage) impose in the drought periods to be applied irrigation in order to assure proper conditions for agriculture. The combination intensive drainage - climate...

Decomposition and Recapture of Ammonium Bicarbonate Draw Solution
ISBN: 9783843379830 / Angielski / Miękka / 168 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A laboratory scale technology that mimics a simple distillation and condensation system was used for decomposition and recapture of an ammonium bicarbonate draw solution. To analyze the recapture performance for this specific application and the influence of system parameters, a test matrix was implemented to address the mass transfer and kinetics involved in the recapture process using 1M, 2M, and 3M ammonium bicarbonate draw solutions. Also, CHEMCAD was used to design a conceptual distillation and condensation recapture and recovery system for a 1000 gpd pilot-scale system. The UNIQUAC...
