  • The constitutive law of plastic deformation expresses the effects of material behavior and properties for stress analysis in the design of manufacturing technology and product service behavior, for materials testing, and for the maintenance of structural and machine components. The book represents the state of the art, but the editors do not rule out other concepts of constitutive laws. There are many different facets of the same problem and as many answers; the right one is the one that gives the most practical solution, the one that best serves the specific problem....

  • Thermal Analysis is a well-established set of techniques for obtaining qualitative and quantitative information about the effects of various heat treatments on materials of all kinds, including new chemical compounds, plastics, ceramics, alloys, construction materials, minerals, foods and medicines. Heating is performed under strictly controlled conditions and can reveal changes in structure and other important properties of the material being studied. Such studies are of great practical importance in the use of materials....

  • This book is the first in a new series devoted to synthetic works in the fields of ecology and evolution. These fields synthesis. Recent examples of synthetic activities include the establishment of the National Center for Ecological Analysis and Synthesis at the University of California Santa Barbara and Deep Green, a worldwide collaboration among angiosperm systematists to determine the phylogenetic structure of the flowering plants. In ecology some of the most important research challenges concern global climate change and the loss of diversity.

  • Antibodies are the paradigm for binding proteins, with their hypervariable loop region supported by a structurally rigid framework, thus providing the vast repertoire of antigen-binding sites in the immune system. Lipoca-lins are another family of proteins that exhibit a binding site with high structural plasticity, which is composed of four peptide loops mounted on a stable b-barrel scaffold.

  • Major oil spills attract the attention of the public and the media. In recent years, this attention has created a global awareness of the risks of oil spills and the damage they do to the environment. However, oil is a necessity in our industrial society, and a major sustainer of our lifestyle. Most of the energy used in Canada and the United States is for transportation that runs on oil and petroleum products. According to trends in energy usage, this is not likely to decrease much in the future.

  • Common engineering materials reach in many engineering applications such as automotive or aerospace; their limits and new developments are required to fulfill increasing demands on performance and characteristics. The properties of mate- rials can be increased, for example, by combining different materials to achieve better properties than a single constituent or by shaping the material or constituents in a specific structure. Many of these new materials reveal a much more complex behavior than traditional engineering materials due to their advanced structure or composition.

  • The "ski-tip" style ends of the robotic retractor blades are longed into the anterior leaflet, then the atrial septum is lifted to visualize PM. The length of the artificial chordae loops were determined with the measure of the distance between the correct plane of apposition on an adjacent normal non-prolapsing segment of the mitral leaflet and the respective PM (done with a More Suture Ruler device). Artificial chordae, with 4 loops each, were constructed of 4-0 PTFE GORE-TEX per the technique by von Oppel and Mohr.

  • To evaluate the main characteristics and performances of alternative financing mechanisms a Multi Criteria Analysis (MCA) was conducted. The MCA is a decision making tool used to reach consensus about the characteristics and performances of different policy instruments, or alternatives. In the MCA each stakeholder participating in the evaluation process enters their judgment (or score), and contributes to a jointly reached conclusion about a policy instrument or alternative. In the FORVALUE study, the MCA was conducted for 11 cases of innovative (or alternative) financing mechanisms.

  • There is no general consensus on how to define various risk-related terms, including the term “risk” itself, and people may have different views on how those terms apply to their particular organization. Both fund boards and advisers would benefit from establishing a common understanding of the terms and concepts they use in risk-related discussions, as well as how they apply to their funds. Some advisers include definitions or descriptions of how they view risk and risk management in their board presentations.

  • This is the third FinCEN study of SARs filed on transactions involving insurance companies and insurance products. A report issued in May 2007 provided a sum- mary of SARs filed in the 10-year period prior to May 2006 by all types of financial institutions regarding suspicious transactions involving insurance companies, insur- ance agents, and insurance brokers. 6 A report issued in February 2003 provided a summary of SARs filed between 1996 and 2002 by all types of financial institutions regarding transactions specifically involving life insurance products.

  • Among other observations, our statistical analysis revealed the dual nature of textbook approaches to international accounting. There is one group of textbooks covering the accounting aspects of company internationalization, with a "monistic" view of accounting systems, in other words one which considers financial accounting and management accounting together; these books are concerned with the accounting dimensions, in the broadest sense, of multinational corporations.

  • The finite element method (FEM) is used widely in analysis of elastoplastic behaviours for structures. The analysis often involves a two-stage process: first, the internal force field acting on the structural material must be defined, and second, the response of the material to that force field must be determined.

  • A univariate descriptive analysis of the quantitative survey data was undertaken to summarise the results for each question. Data was recoded by combining categories as required to facilitate a subsequent bivariate analysis aimed at identifying patterns within the data. Distributions of the respondents’ demographic variables were cross- tabulated with their attitudinal variables and future orientation variables. The coefficients phi, Cramer’s V and Goodman and Kruskal’s gamma were used to measure associations between variables as appropriate.
