  • I have been familiar with plasma spraying in one of the leading thermal spray research laboratories in North America; Centre for Advanced Coating Technologies at the University of Toronto since I started my PhD thesis under supervision of Professors Javad Mostaghimi and Thomas W. Coyle in 2001. Having access to various methods of thermal spraying, diagnostic tools, and processes simulation, I gained experiences in process, deposition, characterization, and simulation of various types of thermal spray coatings....

  • Summary. Turbulence is a complex phenomenon, characterized by many interacting degrees of spatial and temporal freedom. It is widespread, and indeed nearly the rule, in the flow of classical fluids. The complexity of the underlying equations has impeded analytical progress and therefore direct numerical simulations of the equations, as well as experimental work, are key to making further progress. Here, special attention is given to the role of low temperature helium as a test fluid, including the superfluid phase which also exhibits turbulence....

  • This textbook is intended as an introduction to the physics of solar and stellar coronae, emphasizing kinetic plasma processes. It is addressed to observational astronomers, graduate students, and advanced undergraduates without a background in plasma physics. Coronal physics is today a vast field with many different aims and goals. Sorting out the really important aspects of an observed phenomenon and using the physics best suited for the case is a formidable problem.

  • Free radicals are constantly formed in living cells and removed by antioxidant defenses. Antioxidant enzymes are the main line of defense against free radicals in animal and plant cells. Uncontrolled generation ROS are involved in a number of human disease states, including diabetes and cancer due to disturbance in cellular and molecular processes including cell growth, differentiation and proliferation.

  • Nearly all textile materials are colored after fabrication and before final finishing. The coloration of fibers and fabrics through dyeing is an integral part of textile manufacturing. This book discusses in detail several emerging topics on textile dyeing. The pretreatment of textiles prior to dyeing is addressed by several authors. Menezes and Choudhari present chemical alternatives to traditional pretreatment, while Tavcer discusses enzyme pretreatment procedures.

  • In Europe, and more recently in the United States, an increased trend has emerged in the use of autologous blood products in an effort to facilitate healing in a variety of applications. In recent years, scientific research and technology has provided a new perspective on understanding the wound healing process. Initially platelets were thought to act exclusively with clotting.

  • This report originated in 1999 as a result of discussions between the Committee on Solar and Space Physics (CSSP) and officials within NASA’s Office of Space Science Sun- Earth Connections program. As noted in the statement of task (Appendix A), the objective of the study was to provide a scientific assessment and strategy for the study of magnetized plasmas in the solar system. By emphasizing the connections between locally occurring (solar system) structures and processes and their astrophysical counterparts, the study would contribute to a unified view of cosmic plasma behavior.

  • Babies exposed to carbon monoxide during the maturation of their organs may suffer permanent changes to those organs. Studies using newborn rats showed that carbon monoxide exposure could cause changes in the heart muscle tissue. This is turn could increase the severity of effects of artery constrictions when they became adults. Other animal studies have shown that long-term carbon monoxide exposure can contribute to a disease called ventricular hypertrophy, in which the cells of the heart's ventricle chambers are enlarged and possibly weakened.

  • The magnetosphere is an open system that interacts with the solar wind. In this system, solar wind energy continuously permeates different regions of the magnetosphere through electromagnetic processes, which we can well describe in terms of current systems. In fact, our ability to use various methods to study magnetospheric current systems has recently prompted significant progress in our understanding of the phenomenon.

  • The premium price accruing to organic food prod- ucts directly impacts the consumption levels (Aryal et al. 2009). Instead the demand for organic products must be seen in relative proportion of income that is usually spent on food consumption (Tsakiridou et al. 2008). Furthermore, consumer behavior is a dynamic process because of con- tinuous changes in ideas, perceptions and activities of the consumers. Attitude is shaped selec- tively to compromise consumers needs. Learning is gained by experience and it affects consum- ers’ behavior.

  • Volume 3 of the book series Biomathematical and Biomechanical Modeling of the Circulatory and Ventilatory Systems aims at presenting major sets of signaling receptors mainly located at the plasma membrane, 1 in a modeling framework rather than biological perspective. Collecting signaling effectors, their main interactions, and major properties are the first tasks required for any modeling of cell signaling processes. The major objective is to comprehend the complexity of natural phenomena to model these events. In other words, to yield the maximal amount of known information (i.e.

  • Hyaluronan matrices are ubiquitous in normal and pathological biological processes. This remarkable diversity is related to their unique mechanism of synthesis by hyaluronan synthases. These enzymes are normally acti-vated in the plasma membrane and utilize cytosolic substrates directly to form these large polyanionic glycosaminoglycans, which are extruded directly into the extracellular space.

  • The Sun is the primary source of energy at Earth, and the Sun’s output determines the conditions in interplanetary space at Earth and throughout the solar system. Earth’s magnetic field and associated electrical current systems are continuously reacting to changing conditions in the solar wind that are driven by processes occurring at the Sun. The characteristics of Earth’s ionosphere and neutral thermosphere are influenced both by local processes and by coupling of the ionosphere and thermosphere to the overlying regions of the geospace1 environment....
