  • This book is an exploration of the evolutionary process of natural hybridization. My motivation for writing this book comes from the view that crosses between genetically divergent individuals have a major influence on the evolution of some plant and animal species complexes. In particular, I want to examine the role that natural hybridization has as a creative force in organismal evolution. I realize that my emphasis on the "creative" aspect of natural hybridization could lead some to conclude that I believe that this is the only possible outcome from hybridization and gene exchange....

  • Knowing that the plant parameters can vary within their lower and upper bounds, this parametric uncertainty is formulated as an additive perturbation in the transfer function matrix. It is important to note that the controller be designed with respect to worst case uncertainty for each λij. This can be achieved by performing an optimization procedure given by (61) for 200 frequencies. Here an element by element uncertainty bound model is used for the characterization of upper bound of the uncertainty matrix. Then wij , which satisfies (62) for each λij is given in matrix form as,...

  • According to a recent view of culture as a dynamic process (Miller 1995; Shaw and Clarke 1998), cultural differences often cause differences in consumer behavior within and across national borders. Referring to the identification of consumer segments across countries, macro-level geographic, political, economic, and cultural data have been typically used (e.g., Helsen et al. 1993; Kale 1995). In fact, to identify market segments, national borders and the study of culture are appropriate as segmentation criteria when consumer behavior is "culture bound" (e.g.

  • When theaand bchains were separated from human oxyhemoglobin (HbO2), each individual chain was oxidized easily to the ferric form, their rates being almost the same with a very strong acid-catalysis. In the HbO2tetramer, on theother hand, bothchains become considerably resistant to autoxidation over a wide range of pH values (pH 5±11).
