The rapid increase of palm oil (PO) production in the last 20 years has made it the most important oil in the world. By year 2007, the annual global production of PO reached 40 million metric tons. Currently, Malaysia accounts for almost 50% of world palm oil production. As most of natural oils, PO has only a limited application in their original form, as a consequence of its complex chemical c...

Oil and pollutants resulting from its extraction and exploitation are considered as one of the serious problems for human health. Vast oil fields of Ahvaz City located in southern Iran are known as one of controversial subjects in contamination with heavy metals. In this study, oil fields' soils of Ahvaz city (Ab-Teymour) were chemically analyzed in order to determine the concentration of eight...

I review recent developements in the theory of heavy flavour production. In particular, I dicuss the next-to-leading resummation of soft gluon effects in heavy flavour hadroproduction, and the next-to-leading resummation of collinear radiation in the production of heavy flavour at large transverse momenta. 1 Talk presented at the 12 Rencontre de Physique de la Valle d’Aoste, La Thuile, March 19...

Recent experimental results on phow and hadmpmduction of heavy flavor particles are reviewed. After a short introduction on the recent advances in the theoretical ideas describing the production of heavy flavors, current experimental techniques used in heavy flavor search in fixed target experiments an? briefly discussed. New results on the production characteristics, production ctoss section a...

FCC riser; Computational fluid dynamics (CFD); Cracking reaction kinetics; Hydrodynamics; 4-Lump kinetic model; k-Epsilon turbulence model Abstract Fluid catalytic cracking (FCC) is an essential process for the conversion of gas oil to gasoline. This study is an effort to model the phenomenon numerically using commercial computational fluid dynamics (CFD) software, heavy density catalyst and 4-...

Biodegradation of crude oil in subsurface petroleum reservoirs has adversely impacted most of the world's oil, converting this resource to heavier forms that are of lower quality and more challenging to recover. Oil degradation in deep reservoir environments has been attributed to methanogenesis over geological time, yet our understanding of the processes and organisms mediating oil transformat...

A bacterial culture was isolated from oil-contaminated soil based on its ability to metabolize the quinoline as the sole source of nitrogen. In this research Bacillus licheniformis strain was identified based on the result of 16S rRNA analysis. Optimized conditions were obtained with full factorial experimental design method using design expert software at temperature: 32<...

Recent progress in Heavy Flavour Production phenomenology are discussed. In particular, the long-standing discrepancy of the Tevatron b production data is considered. It is shown that a better use of e + e − data in constraining the effect of fragmentation reduces the discrepancy considerably.

We provide a brief overview of some current experimental and theoretical issues of heavy quark production.
