Taschenbuch. Condizione: Neu. Neuware -Project Report from the year 2016 in the subject Energy Sciences, grade: 8, University of Petroleum and Energy Studies, language: English, abstract: The Indian subcontinent is blessed with an ample amount of sunlight almost all through the year. There is an urgent need of switching over to a perennial source of energy as an alternative to replace all the quickly depleting fossil fuels. There is much interest in non-conventional energy nowadays, so as to tap energy from unassuming but promising quarters like Solar, Wind and Tidal energy. Of those, tapping the heat and infra-red rays from the sun, using air and water as appropriate mediums, separately and together as a whole, is the most easiest and versatile way of energy capture.This book is concerned with the designing of an efficient solar parabolic collector to trap the solar heat in the receiver through the combination of concave mirrors. A small scale parabolic dish was fabricated with locally available material like stainless steel for the boiler, and painting it black to increase the absorption. As a matter of application of the project, a solar desalination system was integrated with the project to test the feasibility of the research. The desalination system worked successfully in conjunction with the experimental setup and a reduction in the TDS level of the feed water was observed at the condensation end. Thus, the project is feasible for cleaning or purifying the water by renewable sources. 60 pp. Englisch.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Research Paper (undergraduate) from the year 2012 in the subject Chemistry - Bio-chemistry, grade: '-', , language: English, abstract: Extracellular alpha amylase was produced from Aspergillus oryzae under solid state fermentation. House hold agro-wastes were used as medium which were considered as one of the major pollutants due to unfavorable gas production via natural fermentation beside creating disposal problem. Investigations were carried out to evaluate the effect of various carbohydrate sources e.g. glucose, maltose, lactose, sucrose and soluble starch with different concentrations on the production of fungal alpha amylase utilizing agricultural wastes as the fermentation medium. Studies were also carried out to evaluate the effect of various heat stable amino acids e.g. glycine, histidine, proline, leucine and isoleucine with different concentrations on the production of fungal alpha amylase utilizing agricultural wastes as the fermentation medium. The results indicated that maximum activity of alpha amylase (6639.85 U/gds) was obtained at 0.5% concentration of sucrose solution with a r2 of 0.9692 when compared to control (3319.95 U/gds) and other carbohydrates used. Maximum activity of alpha amylase (10407.80 U/gds) was also obtained at 0.75% concentration of proline solution with an r2 of 0.6816 when compared to control (3035.60 U/gds) and other amino acids used in our present study.…

Druck auf Anfrage Neuware - Printed after ordering - Project Report from the year 2014 in the subject Biology - Micro- and Molecular Biology, grade: PDF, , course: Personal Research Project, language: English, abstract: Ancient rocks and natural oils are rich with abundant and hidden information of ancient organic matters responsible for earth formation, including molecular and isotopic signatures of the organisms that existed at the time the organic matter was formed. Considering the above facts of astrobiology, research study was carried out on screening of oil indicating microorganisms from oil contaminated sites of major geo-political zones of Yobe State, Nigeria including Damaturu, Gashua, Potiskum and Nguru local Government areas. Serial dilution was performed for all soil samples collected from the oil contaminated sites of mentioned local government areas followed by culture isolation and identification techniques for bacterial samples only. Nutrient agar was used for the isolation of the bacteria from the soil samples and mixed cultures were obtained. These bacterial cultures were inoculated in petroleum in order to see their oil utilizing capability. Two types of culture showed positive results among all isolated colonies. Rhizoid shaped gram positive rods isolated from soils of Damaturu, Gashua, Potiskum and Nguru & yellow pigmented gram negative bacterial colony isolated from soils of Potiskum and Nguru showed oil utilizing ability by positive growth in the refined crude oil (Petroleum, Diesel, etc.). The oil utilizing ability of those specific bacteria shows their potentiality in detecting the presence of oil and acting as potential oil indicators in Sub-Saharan region of African Continent caring a long history of bio-geo sciences. Findings from the present research work may create an opening for encouraging the geo-biological potentials of West African Countries in astrobiological aspects.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Project Report from the year 2014 in the subject Biology - Micro- and Molecular Biology, , course: Personal Research Project, language: English, abstract: The aim of the present research work was to study a low-cost production of Lactic acid by fermentation of a non-conventional medium e.g. cheese whey, while considering milk medium as a standard using Lactococcus lactics.The effect of different process parameters such as pH of the medium, temperature, inoculums size, age of inoculums and incubation time was monitored to enhance the lactose conversion in cheese whey to lactic acid. Fermentations were performed without any pH control. The optimization of the fermentation conditions resulted in a significant decrease in fermentation time, besides an increase in lactose conversion to lactic acid. The optimized process conditions resulted in high lactose conversion to lactic acid production (0.539%) after an incubation period of 72 hrs at 37°C.The maximum lactic acid production was 0.767% which was observed when milk media (0.767%) was used as the standard fermentation medium, whereas non-conventional cheese whey medium showed 0.539% lactic acid production at pH 5.5.…
