background and objectives: in the era of global industrialization, enzymes are being used extensively in the various sectors including food processing. owing to the high price of enzymes, various initiatives have been undertaken by the r&d; sector for the development of new processes or improvement in the existing processes for production of cost effective enzymes. with the advancement in the f...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Abstract. With the development of new technology; its use in business processes is expanding rapidly. Accordingly, in recent years the National Statistical Organizations (NSOs), by the recommendations of international statistical organizations in the form of modernization of official statistics, have applied new sciences and technologies in statistical business processes. One of the new science...
What are the problems faced by contemporary artists? By what processes do they solve these problems in real-life? This article presents preliminary results of the second phase of an ongoing project seeking to model the cognitive processes involved in a contemporary artistic practice; this project is being conducted within the artistic creativity as situated problem solving approach. Creativity ...
Because these reactive sites are pendant (not part of the main backbone chain) there are no weak points on the main chain. This is unlike for example Natural Rubber or SBR, where these necessary reactive sites are along the main chain. This means that reactive entities in the atmosphere (for example Ozone, which is very aggressive) can easily attack and degrade these materials. This also explai...

We discuss two novel QCD effecte which enhance the production of heavy quarks and supersymmetric hadrons beyond that conventionally expected from gluon fusion. Invited talk presented at the 12th SLAC Summer Institute on Particle Physics Stanford, California, July 23 August 3, 1984 ir Work supported by the Department of Energy, contract DE AC03 76SF00515. @ Stanley J. Brodsky 1984
Degradation of energy to lower temperatures and the associated production of entropy is a general direction for Earth system processes, ranging from the planetary energy balance, to the global hydrological cycle and the cycling of carbon by Earth’s biosphere. This chapter introduces the application of nonequilibrium thermodynamics to the planetary energy balance of Earth and its neighboring pla...
