Background: Nitrogen is the most important nutrient requirement for plants. Nitrogen supplying affected the leaf area, carbon fixation, glandular trichomes formation, ATP and NADPH content which resulted to the terpenoids biosynthesis enhancement and essential oils accumulation. Objective: This study was aimed to evaluate changes of essential oil content and components by use different levels ...

Crude oil plays an increasingly significant role in world economic development and also in the generation of wealth since nearly two-thirds of the world’s energy consumption comes from crude oil and natural gas. Worldwide consumption of crude oil exceeds $500 billion—roughly 10% of US GDP and crude oil is also the world’s largest and most actively traded commodity, accounting for about 10% of t...

R i c e bran has received increased attention as a feedstuff for swine and as a source of oil for human consumption. Depending on milling conditions and hull contamination, bran from California rice contains 15 to 20 percent oil, 30 to 40 percent digestible carbohydrate, and 12 to 14 percent protein, although levels of up to 18 percent protein have been reported. Rice bran is also an excellent ...

one of the methods to reduce the emissions in a diesel engine is by oxygen introduction into the combustion chamber which can be done by supplying the oxygen into the inlet manifold during suction stroke. oxygen affects different parameters such as brake thermal efficiency, fuel consumption, nox and smoke at different load conditions. load test was conducted for various concentrations of oxygen...

• After palm oil was brought to South East Asia from central Africa in the 20 century the worldwide production has grown by 65 percent over the past decade. Demand is still increasing, especially after the European Union agreed to its 10 percent target for biofuels in their total transport consumption. • As biggest and second biggest producer of palm oil Indonesia and Malaysia account together ...

The effect of groundnut oil on blood glucose, lipid profile, lipid peroxidation, and antioxidant status in streptozotocin-diabetic rats was investigated and compared with diabetic and drug-treated rats. Diabetes was induced in adult female Wistar rats by intraperitoneal administration of streptozotocin (40 mg/kg b-wt). Normal and diabetic rats were fed an oil-free diet containing 2 percent oil ...

is paper examines two major emerging constraints on transport in fast-growing Chinese urban cities: oil supply and urban infrastructure. e research considers automobile technology, alternative fuels, and mobility choices, as well as policy measures that could be adopted to reduce the use of oil for transport and greenhouse gas emissions. ree transport energy scenarios, “Road Ahead,” “Oil Saved,...
