The chemical composition of the essential oil of Helichrysum italicum (Roth) Don ssp. italicum, collected in the National Park of Cilento and Diano Valley, Southern Italy, was studied by means of GC and GC/MS. Forty four compounds of 45 constituents were identified in the oil, mainly oxygenated sesquiterpenes. The essential oil was evaluated for its potential in vitro phytotoxic activity agains...

From 5000 m underground to the surface, there is a multi-layer hydrocarbon reservoir under Wuerhe nose uplift in Junggar Basin. Light oil, heavy oil sand, and solid bitumen are found Permian Cretaceous strata. The normal crude present can easily ignored by explorers. To effectively exploit petroleum mineral resources Basin, geochemical characteristics of oils different layers were analyzed. It ...

This paper examines the value of international cooperation in an oil supply disruption. The perspective is that of oil-importing countries; since the oil market is integrated internationally, the actions of one have spillover effects on the others. We focus on bulTer stock policies, with each player maximizing the present value of national income less the cost of operating the stockpile program...

A study of the ignition of non-fire-resistant hydraulic fluid sprays was conducted by the National Institute for Occupational Safety and Health. Both an open flame and a hot steel surface were used as the external heat sources. With the open flame as the heat source, the minimum oil temperature and minimum spray nozzle pressure that resulted in an ignition were measured. The effects of the dist...

Although the fish-derived, long-chain omega-3 fatty acids (n-3 FA) may be considered “gifts from the sea” for cardiovascular health, the role of the land (or plant) -based n-3 FA -linolenic acid (ALA) has been less clear. ALA is the 18-carbon, 3-double bond (C18:3n-3) precursor to eicosapentaenoic acid (EPA; C20:5n-3) and docosahexaenoic acid (DHA; C22:6n-3), the latter 2 being the predominant ...
