This review summarizes all the research efforts in the last decade (1994-2003) that have been spent to the various application of immobilized enzyme reactor (IMER) in on-line high performance liquid chromatography (HPLC). All immobilization procedures including supports, kind of assembly into chromatographic system and methods are described. The effect of(More)
In this paper we advance the theory that the distribution of beliefs in the market is the most important propagation mechanism of economic volatility. Our model is based on the theory of Rational Beliefs (RB) and Rational Belief Equilibrium (RBE) developed by Kurz [1994], [1997]. The paper argues that most of the observed volatility in financial markets is(More)
OBJECTIVE To generate data on optimal shoulder position comparing two ultrasound-guided extracorporeal shock wave therapy techniques for the treatment of calcifying tendinitis of the shoulder. DESIGN Random assignment to two groups of treatment with three months follow-up. SETTING The data were collected in outpatients. SUBJECTS Thirty-five subjects(More)
Recent studies suggest a considerable amount of horizontal strategic interaction amongst governments exists. The empirical approach in these studies typically relies on estimating reaction functions in a uni-dimensional policy framework, where a nonzero slope estimate suggests strategic interactions exist. While this framework may be useful within certain(More)
This paper considers the question under what conditions domestic markets of emission permits would and should merge to become an international market. Emission permits are licenses, and so governments would need to recognize other countries' permits. In a two-county model, we find that it is in both countries' interests to form an international market, and(More)
OBJECTIVE To describe and compare two extracorporeal shock wave therapy techniques for the treatment of painful subcalcaneal spur. DESIGN Random assignment to two groups of treatment with two and eight months follow-up. SETTING The data were collected in outpatients. SUBJECTS Forty-five subjects with a history of at least six months of heel pain were(More)
In an effort to develop natural and nontoxic inhibitors on the activity of mushroom polyphenol oxidase (PPO) the effect of various glycyl-dipeptides (GlyAsp, GlyGly, GlyHis, GlyLeu, GlyLys, GlyPhe, GlyPro, GlyTyr) was investigated. The inhibition study with dihydroxyphenylalanine (DOPA) as substrate is based on separation of the enzymatic reaction(More)
of 1. Iatroductlon Environmental economics was the subject of a successful research programme in the 1960s and 1970s. This programme dealt with such a wide range of environmental issues and policy problems that Partha Dasgupta, in a recent survey of the subject [see Dasgupta (1990)], claimed the primary environmental issues are now 'very cold' as topics for(More)
