Heat Stress

Heat transfer analysis is a problem of major significance in a vast range of industrial applications. These extend over the fields of mechanical engineering, aeronautical engineering, chemical engineering and numerous applications in civil and electrical engineering. If one considers the heat conduction equation alone the number of practical problems amenable to solution is extensive. Expansion of the work to include features such as phase change, coupled heat and mass transfer, and thermal stress analysis provides the engineer with the capability to address a further series of key engineering problems. The complexity of practical problems is such that closed form solutions are not generally possible. The use of numerical techniques to solve such problems is therefore considered essential, and this book presents the use of the powerful finite element method in heat transfer analysis. Starting with the fundamental general heat conduction equation, the book moves on to consider the solution of linear steady state heat conduction problems, transient analyses and non-linear examples. Problems of melting and solidification are then considered at length followed by a chapter on convection. The application of heat and mass transfer to drying problems and the calculation of both thermal and shrinkage stresses conclude the book. Numerical examples are used to illustrate the basic concepts introduced. This book is the outcome of the teaching and research experience of the authors over a period of more than 20 years.

The first comprehensive treatment of the physiology of plants under stress. "Physiology of Plants Under Stress: Environmental Factors, Volume 1" is a valuable resource for plant physiologists, horticulturists, crop scientists, plant breeders, agronomists, and plant molecular biologists. It provides the most detailed coverage, to date, of the impact of a wide range of environmental variables upon plant structure, development, and growth. Comprehensive in scope, it explores: Plant stress physiology fundamentals, including growth regulation, membranes, phytohormones, carbon balance, and the use of stable isotopes in stress studies. Relevant physical, chemical, and biological aspects of all forms of environmental stress and their effects upon plant metabolism. Multiple levels of adaptation, including behavioral, morphological, anatomical, physiological, and biochemical responses. Plant responses to specific environmental stresses such as drought and flooding, light intensity, high heat, chilling and freezing, and other. recent advances in microbiology and genetic manipulation in the regulation of metabolic influences. And much more. each chapter concludes with study/review outlines and self-study review questions, making this an ideal text for graduate level courses in plant physiology, horticulture, agronomy, and crop science.

Heat shock - Heat shock proteins are a part of the cell's internal repair mechanism. They are also called stress-proteins.

Residual stress - Residual stresses are stresses that remain after the original cause of the stresses has been removed. Residual stresses occur for a variety of reasons, including inelastic deformations and heat treatment.

Wet Bulb Globe Temperature - The Wet Bulb Globe Temperature (WBGT) is a heat stress indicator that calculates three heat stress factors:

Annealing (glass) - Annealing, in glassblowing and lampworking, is heating a piece of glass until its temperature reaches a stress-relief point, that is, a temperature at which the glass is still too hard to deform, but is soft enough for internal stresses to ease. The piece is then allowed to heat-soak until its temperature is even throughout; the time necessary for this varies depending on the type of glass and thickness of the thickest section.
