Microwave Oven $81.25 A microwave oven, or a microwave, is a kitchen appliance that cooks or heats food by dielectric heating. This is accomplished by using microwave radiation to heat water and other polarized molecules within the food. This excitation is fairly uniform, leading to food being adequately heated throughout except in thick objects, a feature not seen in any other heating technique. Basic microwave ovens heat food quickly and efficiently, but do not brown or bake food in the way conventional ovens do. This makes them unsuitable for cooking certain foods, or to achieve certain effects. Additional kinds of heat sources can be added to microwave packaging, or into combination microwave ovens, to add these additional effects. Microwaving food raises several safety issues, but also reduces certain risks, such as that of fire from high temperature heat sources.

The Physics of Solar Flares $101.96 Few phenomena have stirred the imaginations of solar scientists as much as the explosive energy of solar flares. In The Physics of Solar Flares, first published in 1988, Einar TandbergHanssen and A. Gordon Emslie approach this subject by drawing heavily on experimental data from the Solar Maximum Mission, as well as other groundbased and spaceborne instruments. The data are incorporated into many theoretical investigations. The authors put the main emphasis on understanding the underlying physical processes. Starting from the language of physics, the authors guide the reader into the more specialised concepts of solar physics. The book is divided into two main parts: four chapters set the essentials of physics needed to attack the complexities of flare phenomena, and then a further four treat different aspects of the phenomena. This important book is aimed primarily at beginning graduate students who are assumed to have knowledge of basic physics. Author: TandbergHanssen, Einar/ Emslie, A.

A Survey of Passive Solar Buildings $35.09 This publication of passive solar projects built in the United States has been prepared to document the state of the art in passive solar design. Passive solar heating and cooling can provide a major percentage of the buildings energy requirement, while at the same time representing a heightened level of involvement for the architect in the design stages of the building. The full potential of this passive conditioning depends on a sensitive awareness of the relationship between climate, comfort, and the thermal characteristics of buildings and building materials. Passive solar systems are often misunderstood and vaguely defined. Many of the approaches to passive solar heating and cooling are at rudimentary stages, with little performance data and evaluation, few modeling techniques, and minimal published information. Yet for the building designer and the occupant, these concepts have major implications in the design and use of buildings. The purpose of this publication is to offer a working definition and a basic understanding of a number of existing applications of passive solar designs. Methods of passive solar design are not presented in this publication; nor are rules of thumb or passive solar assemblies and components. These subjects will be addressed in later publications. A reference bibliography has been included to assist the reader who desires more information and to stimulate additional individual research and testing. Passive design techniques can be integrated in an additive fashion in more typical buildings but this challenge for now, is left to the reader.
