Biogas containing approximately 60% methane can be produced from paddy straw -a lingocellulosic waste, by anaerobic fermentation using cattle dung as source of inoculum .The total gas production from the paddy straw is more in comparison to that of cattle dung as substrate. But pretreatment of paddy straw with NaOH can reduce the Holding Retention Time significantly. Moreover paddy straw is able to supply higher yield of biogas due to its slow decomposition .The digested slurry was found to be a very good source of manure. Biogas containing 60% ....etc

Biogas Generation and its Utililities



.Typically 55% methane (CH4) 45% carbon dioxide (CO2) H2S and H2O and trace gases
.Energy comes from methane only
.Energy value of methane 37.78MJ/Nm3
.Energy value of biogas 21MJ/Nm3

Anaerobic digestion technology

In the absence of dissolved oxygen, anaerobic microorganisms will tend to ferment biodegradable matter to carbon dioxide and methane which can be collected and use as a fuel. This process is called anaerobic digestion ....etc

ABSTRACT
Throughout history, humans in society have had a need to determine the identity of individuals who have committed crimes. In the last century, there has been unprecedented progress in developing accurate, scientific methodologies for connecting a suspect with a crime. This paper reports the discovery of Brain Fingerprinting, a new technology that uses brain waves to connect evidence stored in the brain of a suspect with evidence connected with a crime, and discusses Brain Fingerprinting from the perspective of scientific progre ....etc

ABSTRACT

The rectifier and inverter are used in vector control of induction motor. The most shortcomings are that exist a big capacitor and energy pass only from power sources to load. This paper details a novel matrix converter-indirect matrix converter. It is used in vector controlling research of induction motor and displaced for conventional inverter to supply power for induction motor. Because switches are bidirectional in the rectifier, it can realize bidirectional pass of the energy and decrease pollution of harmonic wave. Meanwhile b ....etc

EXPERIMENTAL INVESTIGATIONS ON A 4-S C. I. ENGINE USING ALTERNATE FUELS



INTRODUCTION

Dr. Diesel used peanut oil as fuel in his engine. A lot of research on vegetable oils as fuels was carried out 60 years ago, but interest lagged because of cheap and plentiful supplies of petroleum at that time.

Rapid depletion of petroleum fuel and environmental pollution problem led man to search for alternate fuels again. At present the world is highly dependent on petroleum fuels and ....etc
