various combustion characteristics and properties are studied while selecting a fuel for any engine. the choice of the engine and fuel are highly interrelated. vegetable oil is one obvious fuel particularly because their fuel properties are closer to diesel fuel. two important properties, the cetane number and the calorific value are similar to diesel. hence diesel engines can be operated on ve...

The unique properties of DNA make it a fundamental building block in the fields of supramolecular chemistry, nanotechnology, nano-circuits, molecular switches, molecular devices, and molecular computing. In our recently introduced autonomous molecular automaton, DNA molecules serve as input, output, and software, and the hardware consists of DNA restriction and ligation enzymes using ATP as fue...

Yogurt production at the farm level is important for adding value to milk. In this study, a solar-assisted yogurt processing unit capable of performing three processes heating, fermentation, and cooling in single was developed. It consisted circular chamber surrounded by coil heating solar vacuum tube collector pillow plate PV-powered chiller unit. Experiments were performed using 50, 40 30 L r...

The occurrence of Microcystis blooms is a worldwide concern that has caused numerous adverse effects on water quality and lake ecology. Elevated ammonia and microcystin concentrations co-occur during the degradation of Microcystis blooms and are toxic to aquatic organisms; we studied the relative and combined effects of these on the life history of the model organism Daphnia magna. Ammonia and ...

hydrocarbons are prone to bacterial and fungal contamination. bacteria and fungi live and proliferate in water droplets within the fuels and on surfaces surrounding them. this can cause corrosion in oil exploration and production, clogging of fuel lines in aviation and higher emissions in diesel combustion engines to state few examples. state-of-the-art is the addition of biocides to fuels, whi...

Previous experimental studies have shown that addition of small amounts of oxygen to a hydrocarbon fuel stream can control coking in the anode, while relatively large amounts of oxygen are present in the fuel stream in single-chamber solid oxide fuel cells SOFCs . In order to rationally design an anode for such use, it is important to understand the coupled catalytic oxidation/ reforming chemis...

D uring the past 50 years, wastewater treatment has improved the quality of our navigable waters and the health of our environment. This achievement has not been accomplished without considerable capital investment by our nation, and we know that large expenditures will continue to be needed. It has been estimated that $2 trillion will be needed in the United States alone over the next 20 years...

background: dengue is amongst the most serious mosquito-borne infectious disease with hot spots in tropical and subtropical parts of the world. unfortunately, no licensed vaccine for the disease is currently available in medicine markets. the only option available is the management of dengue vector mosquito, aedes aegypti (diptera: culicidae). method: predatory potential of five odonate nymphs ...
