Heroin, a synthetic derivative of the p opioid receptor agonist morphine, is a well-documented narcotic that alters mood and rewarding behaviors. To date, heroin is the most abused opioid with an estimated 750,000-1,000,000 hardcore users in the... 

One Holy Grail in protein structure is to develop tools that accurately predict three-dimensional structures of proteins from their primary sequence information [58, 59]. Many of the best tools to date only go part of the way by using known three-dimensional structures from proteins which share similar primary sequence to model the possible structures of new proteins. This technology still has a long way to go, but the potential rewards would be enormous, allowing a genome sequence to be translated into targets for therapeutic intervention in si-lico, in relatively short periods of time. 

Illustrative performance properties for a "general purpose polycarbonate," and for the same resin modified with the additive formulations "700" (without PTFE) and "800" (with PTFE) are summarized in Table IV (adapted from reference 32). It is clear that the objective of minimal effect on performance properties has been attained for this system. It is evident that flame retardant effectiveness attained with minimal levels of additive can provide optimum solutions to the problem of decreasing flammability without sacrifice in performance properties. Work documented to date suggests that in depth studies of thermal degradation such as reported for aromatic sulfonates in polycarbonates (28) would be rewarding for other systems. 

As suggested by Beauchamp s group, a female s unlearnt attraction to male-soiled bedding is probably reflecting the rewarding properties of sexual pheromones. To date, the only attempt to demonstrate this hypothesis rendered inconclusive... 

There is evidence that nicotine also stimulates the DA projections to the dorsal striatum (BenweU and Balfour 1997 Quick 2004). To date, relatively few studies have sought to directly link this response to the drug with behavioural changes associated with dependence. Nevertheless, a number of studies have implicated these projections in the responses to rewarding stimuli, particularly in expectation of reward (Schultz 2006). A failure to deliver an anticipated reinforcer results in transient reduction in the activity of these neurones. Rice and Cragg (2004) have reported that... 

Viscometer design to fill simultaneously the needs of quality-control and production personnel as well as development engineers would appear to be a stimulating and rewarding field to which, evidently, little intelligent attention has been given to date. 

Beflexible in scheduling rewards. It is easier to establish a credible pay-for-performance plan if all employees do not receive pay adjustments on the same date. 

Twentieth-century chemistry has evolved into numerous subdisciplines closely connected with subdisciplines from the other sciences. Physical chemistry, chemical physics, biochemistry, clinical chemistry, and nuclear chemistry are well known examples. [1] The connections to the earth sciences and the astronomical sciences are much less known and have received relatively little historical attention. Yet these interdisciplinary fields are extremely rich and have histories that are rewarding subjects for the historian of science. The purpose of the present paper is to provide a historical introduction to what is currently known as cosmochemistry, or the chemistry of the universe. In one sense, this is a modern branch of science, established only in the 1950s, but it can be plausibly traced back to the late nineteenth century, if not earlier. It can even be argued that it dates back to about 1800, when meteorites were first subjected to chemical analysis. 

Any serious research effort directed towards achieving a commercial reward and patent protection needs assistance from adequate information services. Besides the scientific literature, related patents and patent applications must be available and can be traced through patent data bases and patent libraries. Computerized patent data bases (Table 10) usually contain all front page information of a patent or patent application, such as patent number, applicant, inventor, filing and priority date, title of the invention and the abstract, in some cases also the patent claims. Full copies of selected patents can be ordered from national patent libraries or from the patent office. 

The authors primary aim in writing this book was to provide an overview of appropriate length to help analytical chemists assess the potential uses of ultrasound in a variety of chemical fields. Another aim was to discuss ultrasound-based detection techniques in a systematic manner in order to clear the enormous confusion around some concepts. The authors would like to apologize in advance for any significant omissions resulting from the vast scope of the topic and the absence of analytical chemists with whom to discuss some specially elusive aspects of ultrasound. As long as readers believe the book provides them with an up-to-date, balanced description of the potential of ultrasound in analytical chemistry, the authors will feel rewarded for the effort. 

A sensitive test for neurological effects of gestational exposure to methylmercury is operant behavioral performance (i.e., rewarded responses to total lever presses). Bomhausen et al. (1980) reported a significant reduction in operant behavioral performance in 4-month-old rat offspring exposed to methyl-mercuric chloride at 0.008 mg Hg/kg/day on Gd 6-9. A dose of 0.004 mg Hg/kg/day did not alter the behavioral performance of the offspring. No other studies have confirmed this result to date. 

The present book is a result of the efforts of 37 co-workers and the editors would like to express their gratitude to all those who contributed to this book and the respective companies and institutes which made this possible. In retrospect we have to admit that the co-operation of such a diverse crew of authors was not always easy to co-ordinate. In this context, we would like to express our deep gratitude to all those patient contributors who, despite the delays caused by those who were either late in submitting or who completely refrained from doing so, did not hesitate to keep their articles up-to-date. It is especially gratifying for us to see that our joint efforts have been rewarded by the present collection of articles which tries to capture the current state of knowledge.
