  • Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environmental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment.

  • Heterocyclic Chemistry represents a vast and important area of research which is of interest to a wide spectrum of chemists. This is amply documented by the fact that various journals, societies, and interest groups have sprung up entirely devoted to the pursuit of heterocyclic chemistry. Surprisingly though, there exists to our knowledge no single periodical review alerting the reader on an annual basis to important developments of the subject. We have now been able to persuade...

  • The metastable state of liquids which are supercooled has been the subject of interest for over 300 years. Supercooled water and aqueous solutions are found in the atmosphere, in cold-hardy organisms, and in many industrial applications. For example, freeze tolerance and the associated avoidance of supercooling, is the dominant cold-related strategy in Southern Hemisphere insects, being found in 77% of cold hardy insects. In industry, thermodynamic systems such as cool boxes have a significant financial driving force for supercooling to be controlled and this is also covered in this book....

  • This paper tests whether self-control problems are relevant in real market settings. This is important because much of the empirical support for the self-control problem framework comes from laboratory experiments (see Fredrickson, Loewenstein and O’Donghue, 2004; Thaler, 1999). Departures from the standard model could disappear in real market settings, due to higher incentives, greater opportunities for learning, or differences between the population of subjects typically used in experiments and the general population (see List, 2003, for a discussion of these points).

  • Human amylin (hA) is a small fibrillogenic protein that is the major con-stituent of pancreatic islet amyloid, which occurs in most subjects with type-2 diabetes mellitus (T2Dm). There is growing evidence that hA toxic-ity towards islet b-cells is responsible for their gradual loss of function in T2Dm. Preventing hA-mediated cytotoxicity has been proposed as a route to halt the progression of this disease, although this has not yet been dem-onstratedin vivo.

  • Architecture continually informs and is informed by its modes of representation and construction, perhaps never more so than now, when digital media and emerging technologies are rapidly expanding what we conceive to be formally, spatially, and materially possible. Digital fabrication, in particular, has spurred a design revolution, yielding a wealth of architectural invention and innovation. How designs use digital fabrication and material techniques to calibrate between virtual model and physical artifact is the subject of this book.

  • Like most technical disciplines, environmental science and engineering is becoming increasingly specialized. As industry professionals focus on specific environmental subjects they become less familiar with environmental problems and solutions outside their area of expertise. This situation is compounded by the fact that many environmental science related terms are confusing. Prefixes such as bio-, enviro-, hydra-, and hydro- are used so frequently that it is often hard to tell the words apart.
