A significant share of the world's undiscovered oil and natural gas resources are assumed to lie under the seabed of the Arctic Ocean. Up until now, the exploitation of the resources especially under the European Arctic has largely been prevented by the challenges posed by sea ice coverage, harsh weather conditions, darkness, remoteness of the fields, and lack of infrastructure. Gradual warming...

In the present study, jatropha oil cake (JOC), a waste produced from processing jatropha seeds for biodiesel production, has been investigated for the removal of nickel (II) from aqueous solutions. Jatropha oil cake contains different functional groups that can participate in the metal ion complexation. Jatropha oil cake is used in its natural form (JOCN) as well as in its immobilized form (JOC...

Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 +/- 1 degrees C), RH (60 +/- 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean a...

Implementation of hydraulic fracturing dramatically altered the fundamentals in the oil and gas markets. A new technology rst got implemented in the natural gas market, but by 2012 unprecedentedly low gas prices forced most exploration rms to switch to shale oil exploration. Large capital expenditure on drilling activity resulted in the growth of oil production in the US, and likely triggered t...

The 'paradox of plenty' and the 'resource curse' hypotheses claim that abundance in natural resources, particularly oil, encourages civil war through a number of causal mechanisms. Natural resources provide both motive and opportunity for conflict, rent seeking slows down growth and renders state institutions weak thus creating indirect causes of violent conflict. Contrarily, the theory of the ...

Abstract This study aims at exploring the improvement in extreme pressure (EP) properties with addition of natural Garlic oil as EP additive. Comparative investigations were conducted on PAO4 base oil, Natural (NGO) and +1 wt. % NGO (Natural Oil) for evaluating properties. The tests a four ball tester according to ASTM D 2783. results revealed that possesses significantly good having weld load ...

Natural product herbicides for vegetation control are being considered as alternatives to synthetic herbicides by many public agencies. Studies were conducted along roadsides at the Hopland Research and Extension Center (HREC) in 2001 and 2002 and on California State Route 29 (SR29) in 2002 to evaluate acetic acid, pine oil, and plant essentials compared with glyphosate for control of herbaceou...

francoeuria undulata (l.) lack is often synonymous with two species of the genus pulicaria,i.e. pulicaria undulata (l.) c.a. mey and pulicaria crispa (forssk.) olive, which are oftenincluded under the genus francoeuria. the essential oil yield and compositions in the fivenatural populations of francoeuria undulata from fars province in southern iran weredetermined by gc and gc/ms analysis. the ...
