this research was carried out to assess the effect of drought stress on head branch dry weight, photosynthesis, essential oil yield and radical scavenging of rosemary (rosmarinus officinalis l.) in islamic azad university, shoushtar branch, iran during 2010-2011.the experiments were carried out using complete randomized block design with four replications and drought stress levels included cont...

Cucurbita pepo subsp. pepo var. Styriaca is a phylogenetically young member of the Cucurbita spp. since the mutation leading to dark green seeds with stunted outer hulls arose only in the 19th century. This mutation defined the so-called Styrian oil pumpkin and facilitated the production of Styrian pumpkin seed oil. It is a regional specialty oil in the south-eastern part of Europe. In this art...

Renewed political and commercial interest in the resources of the Arctic, the reduction in the extent and thickness of sea ice, and the recent failings that led to the Deepwater Horizon oil spill, have prompted industry and its regulatory agencies, governments, local communities and NGOs to look at all aspects of Arctic oil spill countermeasures with fresh eyes. This paper provides an overview ...

in the form of passive seismic methods, broadband seismometers have been used in hydrocarbon exploration. the frequency bandwidth typically studied is in the range of 1–6 hz. the observations on low frequency band of microtremors are used to calculate the spectral ratio of vertical and horizontal components (v/h) and power spectral density (psd). attributes based on the v/h ratio and the psd ha...

A lot of oil and gas reservoirs have been or will be abandoned in petroleum industry. In this study, we pointed out that these oil and gas reservoirs might be transferred into exceptional enhanced geothermal reservoirs with very high temperatures by oxidizing the residual oil with injected air. A concept to generate power from these exceptional enhanced geothermal reservoirs by using geothermal...

Topical application of 2% neem oil mixed in mustard oil provides 86.1% protection for about 7 hours against the bite of Phlebotomus papatasi (Scopoli) under laboratory conditions (Sharma and Dhiman, 1993). One ml of 5% neem oil in acetone applied to cardboard mats when used on electric heating device marketed for use for synthetic pyrethroid mats, have been reported 100% effective as space repe...

Field and laboratory investigations were undertaken at Nagarjun Medicinal Plants Garden from 1984 - 1987 with object to find out the suitable variety of palmarosa having high yield of foliage and oil. From the pooled analysis the variety IW - 3631 showed highest dry foliage yield (10271 KG / ha) which was significantly superior over all varieties i.e, IW 3632, IW-3630, IW RRL (B) - 65 and IW - ...

Industrial growth has accelerated the emission of various oily water from the sources such as petrochemical and metallurgical industries,transportation, & domestic sewage which contains 70% free oil,25% emulsified, 5% soluble oil. The Present work was inspired by a small note published in science reporter.Keeping the concept in mind , the subject is explored further and its application in the f...

This paper reviews our knowledge of 011-pollution effects on coral-reef communities, concentrating on research done since the last review on this subject by Johannes (1975). The review focusses on crude-oil effects on scleractinian corals and octocorals and summarizes the small amount of work conducted on other reef organisms, as well as on the reef flora. Until 1975 there appeared to be no con...
