Fundamentals of Air Pollution Engineering.pdf

Taken from Preface: Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years. Nonetheless, the development of combustion modifications aimed at minimizing the formation of the unwanted by-products of burning fuels requires an understanding of the combustion process. Fuel may be available in solid, liquid, or gaseous form; it may be mixed with the air ahead of time or only within the combustion chamber; the chamber itself may vary from the piston and cylinder arrangement in an automobile engine to a lO-story-high boiler in the largest power plant; the unwanted byproducts may remain as gases, or they may, upon cooling, form small particles.

Nuclear Magnetic Resonance Applications to Organic Chemistry.pdf

Taken from Introdution: The development of nuclear magnetic resonance spectroscopy subsequent to the initial discoveries by Purcell and Bloch in 1946 is now recognized as one of the most important events in the last fifty years for the advancement of organic chemistry. Nuclear magnetic resonance (NMR) techniques are throwing new light on many difficult organic problems. With the possible exception of gas-liquid chromatography, no new experimental method has been so rapidly accepted or proved so widely applicable. It is the purpose of this book to present the elements of NMR spectroscopy in a form suitable for practical use by organic chemists. Examples of applications will be mainly drawn from high resolution proton resonance spectroscopy, but the principles so illustrated will often be useful in dealing with other types of NMR spectroscopy.

Taken from “Real Life Technology”: The High-line instrument panel features 4 analogue indicators, 19 indicator lights, segment display (distance travelled, time) and a large Maxi DOT display showing data from the on-board computer such as outdoor temperature, fuel consumption and mileage. The Maxi DOT further displays easily legible information on fuel reserve, oil pressure, cooling liquid level etc. The advantages of the Maxi DOT include the ability to communicate information from the radio, telephone and navigation system.

The Thermodynamics of Phase Equilibrium.pdf

October 9, 2009 · Filed Under Physics · Comment  · Tags: ,

Taken from Introduction: This paper is the first in a series in which thermodynamics is developed beyond its usual scope from a new postulational basis. The postulational basis of classical thermodynamics is firmly established in tradition and a new departure calls for an explanation of the underlying ideas. It is widely believed that thermodynamics consists essentially of the implications of the first, second, and third law of thermodynamics. Actually, however, few if any significant results can be derived from these postulates without using a number of additional assumptions concerning the properties of material systems, such as the existence of homogeneous phases, validity of equations of state and the like.
