concentration of behenic acid. The refined oil is clear and odorless‚ and resists rancidity. The seed cake remaining after oil extraction may be used as a fertilizer or as a flocculent to purify water. Moringa seed oil also has potential for use as a biofuel. Previous researchers have extracted Moringaoleifera oil by using different methods such as solvent and aqueous enzymatic extraction (Abdulkarim et al.‚ 2005) but focussed on the study of the physicochemical properties of the oil obtained.

nineteenth and twentieth centuries‚ people believed that fossil fuel reserves would be exhausted and focused their attentions on sources of renewable energy. This led to experiments with solar steam for industry and solid wood‚ methanol gas‚ or liquid biofuels for engines. Attention has refocused on renewable energy sources since the 1960s and 1970s‚ not only because of concern over fossil fuel depletion‚ but also because of apprehension over acid rain and global warming from the accumulation of carbon

Relation among Agriculture‚ Trade and Industry: Many industries running in Nepal are based on agriculture. Such industries are dependent on the raw materials that come from agriculture sector. The examples are sugar industry from sugarcane‚ jute industry from jute‚ cotton factory from cotton‚ leather industry from animal skin‚ tea factory from tea leaves‚ etc. To run these industries‚ raw materials are made available from the agriculture sector. Agriculture tools like spade‚ plough‚ etc are produced

New renewables (small hydro‚ modern biomass‚ wind‚ solar‚ geothermal‚ and biofuels) accounted for another 3% and are growing very rapidly.[1] The share of renewables in electricity generation is around 19%‚ with 16% of electricity coming from hydroelectricity and 3% from new renewables.[1] The use of wind power is increasing at

A major ongoing issue in the world is the pollution of our atmosphere‚ one the factors that contributes to the pollution of our atmosphere is Gasoline which produces CO2 and is emitted into the atmosphere when Gasoline is used. There are 7 major alternate resources for Gasoline that will not only be beneficial to the Earth’s environment but may be less expensive than Gasoline. One of the 7 major alternate source for Gasoline is the fuel Ethanol. Ethanol is a renewable fuel made from corn (not necessarily

Diesel’s original idea was to run the diesel off biofuel to make it more practical for the common person to use. In the 1920’s the new fuel injection pump was invented witch made the engine small enough for it to be made mobile. The first auto company to come out with a diesel engine in an automobile
