Murine thioglycollate-elicited peritoneal macrophages were cultured in the presence of a variety of fatty acids added as complexes with bovine serum albumin. All fatty acids tested were taken up readily by the cells and both neutral and phospholipid fractions were enriched with the fatty acid provided in the medium. This generated a range of cells enriched in saturated, monounsaturated or polyu...

In this experiment, 0, 0.125, 0.25, 0.5, and 1.0 ml of each oil dissolved in 1 ml of 95 % ethanol was added to 1 kg of soil containing 370 P. penetrans per kg, and incorporated by shaking. After 10 days at 22 ± 3 C, a four-week-old tomato (Lycopersicon esculentum Mill cv. Bonny Best) seedling was planted in each of six 5-cm-diam plastic pots containing 100 g of treated or untreated infested soi...

A two-stage reactor system consisting of co-pyrolysis biomass and plastic in the 1st stage catalytic upgrading (zeolite ZSM-5 catalyst) derived pyrolysis gases 2nd was used to investigate yield composition product bio-oil. Biomass waste wood plastics form high density polyethylene, low polypropylene, polystyrene polyethylene terephthalate were as feedstock. The addition with co-pyrolysis-cataly...

Plastics are a ubiquitous part of modern life. They can be modified to meet the demands of almost any conceivable application1. While plastic is extremely useful and has been very important in the development of society since the beginning of the 20th century, it also presents a problem. It is estimated that 25 Mt of plastic waste was generated in the European Union in 2008. As much as 49 % of ...

Chalk is the constituent material of numerous oil reservoirs in North Sea. The mechanical behaviour of a saturated chalk has been largely studied. However, different aspects of its behaviour are not yet well understood: material characteristics depend on the saturating fluids and chalk response is timedependent. This paper proposes the PASACHALK numerical model: an elasto-plastic constitutive l...

Within the last few decades, plastics have revolutionized our daily lives. Globally we use in excess of 260 million tonnes of plastic per annum, accounting for approximately 8 per cent of world oil production. In this Theme Issue of Philosophical Transactions of the Royal Society, we describe current and future trends in usage, together with the many benefits that plastics bring to society. At ...

Efficacy of Cinnamon bark oil vapour (Cinnamomam verum Presl.) and Citronella oil vapour (Cymbopogon nardus L.) were evaluated for the control of infestations of Callosobruchus chinensis L in bulk stored green gram. Both oils were used at 5ml and 10ml/5kg of seeds in 3L plastic baskets. Oviposition and damaged seeds were detected for up to two months of period. At the end of the storage period,...

The rapid increasing the industrialization, motorization, in the world has remarkably raised the demand of the petroleum products. The reservations of such a petroleum based fuels are limited in the world. Furthermore, they are exhaustible and cost is rapidly increasing day to day. For those countries having not ability of petroleum recourses, are importing the petroleum fuels. So, it is quit n...

One remaining issue of CO2 processes are problems in connection with the lubrication oil. The objective of this project is to prove the feasibility of a small oil free semi hermetic piston type CO2-compressor for supercritical heat pump applications with large temperature spans. These processes involve high pressures like 35 bar suction pressure and 80 to 150 bar delivery pressure. A functional...
