Abstract:

Abstract The increasing awareness of the depletion of fossil fuel resources and the environmental benefits of biodiesel fuel has made it more attractive in recent times. The cost of biodiesel, however, is the major hurdle to its commercialization in comparison to petroleum-based diesel fuel. The high cost is primarily due to the raw material, mostly neat vegetable oil. Used cooking oil is one of the economical sources for biodiesel production. However, the products formed during frying, can affect the transesterification reaction and the biodiesel properties. This paper attempts to review vari

Abstract:

The oil and gas industries use sophisticated logging tools during and after drilling. These logging tools employ internal electronics for sensing viscosity, pressure, temperature, and other important quantities. To protect the sensitive electronics, which typically have a maximum allowable temperature of 100 㬠they are shielded and insulated from the harsh external drilling environment. The insulation reduces the external heat input, but it also makes rejection of the heat generated within the electronics challenging. Electronic component failures promoted by elevated temperatures, and thermal

Abstract:

In addition to its various military applications, shaped charges have been used in oil industry as an oil well perforator (OWP) to connect oil and gas to their reservoirs. The collapse of the liner material under the explosive load produces a hypervelocity jet capable of achieving a deep penetration tunnel into the rock formation. The achieved penetration depends on the OWP design, which includes the geometry and the material of the explosive and the liner as well as the initiation mode and the casing of the shaped charge.

The world is moving toward the renewable energy resources. Biogas is a renewable energy resource with high energy value and low CO2 emissions. Biogas is a gas mixture, mainly consisting of methane and carbon dioxide, resulting from the biological process of anaerobic digestion of various organic material. Vegetable oils contain lipids which are excellent substrate for anaerobic digestion as they produce high amount of biogas compared to other substrates like proteins. But one of the major problems attached with the lipids is that they are insoluble in water and form biphasic solution making it

Abstract:

Background: Since the initiation of assisted reproduction techniques, several studies has been performed to improve treatment results by development of culture conditions like embryo oil and culture media used. In this study, two embryonic oils from different companies, Nidoil and Ovoil were examined.Method: In this study, 47 human embryos were used. All embryos were donated for research purposes by couples who had been treated at the clinic in Uppsala University Hospital. The embryos were divided into two groups, one group was cultured with Ovoil and the other with Nidoil.Results: There was n

Abstract:

O óleo lubrificante mineral é amplamente utilizado no cenário mundial no funcionamento de máquinas e motores. No entanto, o ciclo de vida deste petro-derivado resulta na geração de um resíduo (óleo lubrificante usado), o qual é nocivo ao meio ambiente quando não descartado adequadamente ou reciclado. No Brasil, apesar das normas que tratam especificamente do armazenamento, recolhimento e destino de óleo lubrificante usado, grande parte do mesmo ainda é despejado diretamente no meio ambiente, sem qualquer tratamento, sendo de grande importância estudos que visem o entendimento dos processos e o

Abstract:

Government officials in the Caribbean are encouraging the production of electricity from renewable energy sources to reduce the impact of high electricity rates to customers due to region's dependency on imported fossil fuel. The purpose of this single-case study was to explore the strategies electric utility managers in the Caribbean used to implement renewable energy technologies. The diffusion of innovation theory served as the conceptual framework for the study. Three managers of an electric utility in the Caribbean, who had created strategies to implement renewable energy technologies, pa

Abstract:

This thesis examines the joint venture relationship in the context of the exploration phase of the development of an oil and gas field in Great Britain and Australia. It considers a number of issues relating to the relationship between the Participants of a typical Joint Operating Agreement within the legal regimes of Great Britain and Australia. Against this background the main issues addressed in this thesis are- 1. the nature of the joint venture?; 2. the relationship between the Participants inter se; and 3. the relationship between the Operator and the Participants. In addressing these is

Abstract:

The current economic and social conditions in many rural areas of the world are threatening the precious heritage of ethnobotanical knowledge and traditional farming practices.This can cause loss of precious cultural heritage and reduction in plant biodiversity, as ancient crops tend to disappear. The main aim of this thesis is to document traditional uses of plants by different ethnic groups (Tibeto-Burman and Indo-Aryan) living in certain rural areas of the Kavrepalanchok District in Central Nepal.
