In January 2019, the Canadian province of Alberta enacted limits on crude oil and bitumen production. These production controls, a policy referred to as curtailment, represent shift for government that historically avoided market intervention. The was designed shrink growing prolonged price differential between Western Select oil, key benchmark Alberta’s heavy production, West Texas Intermediat...

Securing new sources of energy has become a major concern, because fossil fuels are expected to be depleted within several decades. In some of the major wars of the 20th century, control of oil was either a proximate cause or a decisive factor in the outcome. Especially in Japan and Germany, a great deal of research was devoted to making liquid fuels from coal. In one such experiment, a large a...

Biosurfactants are widely known as surface active agents of biological origin. Glycolipid classes of biosurfactants has high important in the biotechnological arena. Pseudomonas aeruginosa, Bacillus subtilis, and Candida sp., are important classes of microorganism and highly investigated for the production of glycolipid biosurfactants. Commercially, microbial biosurfactants are more advantageou...

We review the present theoretical and experimental status of heavy quark production in high-energy collisions. In particular, we cover hadroand photoproduction at fixed target experiments, at HERA and at the hadron colliders, as well as aspects of heavy quark production in e+e− collisions at the Z0 peak.

A number of possible mechanisms have been suggested to generate density inhomogeneities in the early Universe which could survive until the onset of primordial nucleosynthesis 1]. We studied the eeect of such inho-mogeneities on primordial nucleosynthesis. One of the proposed signatures of inhomogeneity, the synthesis of very heavy elements by neutron capture, was analyzed for varying baryon to...
