In business it is often necessary to apply a mathematical framework in order to solve everyday problems. This text takes a problem- and context-driven approach with the mathematics introduced only on a need-to-know basis. Care is taken not to overwhelm the student with mathematical techniques but to relate these techniques to specific business areas. The only exception to this form of presentation will be in the first two chapters where the elementary basics of arithmetic and algebra are displayed - albeit here, within financial and commercial contexts as well.

This is an introductory text intended to give the newcomer to this area a comprehensive insight into the science of biotransformations. The book traces the history of biotransformations, clearly spells out the pros and cons of conducting enzyme-mediated versus whole-cell bioconversions, and gives a variety of examples wherein the bio-reaction is a key element in a reaction sequence leading from cheap starting materials to valuable end-products (such as pharmaceuticals and agrochemicals, fragrances and flavors). The authors cover biotransformations involving the hydrolysis of esters, amides and nitriles, the synthesis of esters and amides, reduction and oxidation reactions and carbon-carbon bond-forming systems. The book finishes with a discussion of some industrially important large-scale bioconversions. The text will be suitable for advanced undergraduates, graduate students, and professionals in the areas of biochemistry, organic chemistry, biotechnology, microbiology, and industrial chemistry.

The science (or even the art ) of instrumentation is of fundamental import ance to engineers, scientists and medical workers. Instruments are the eyes and ears of the technologist. (His nose is reserved for detecting the effects of excess current. ) Without sensors and their associated signal processing systems there would be no modern transport, no National Grid distributing electricity, and anyone unlucky enough to fall ill would be offered only the most primitive medical treatment. The progress that has been made in almost all areas of technology can be seen in terms of the rate at which the necessary instrumentation has been developed. For example, in recent years many improvements have been made to the performance of the internal combus tion engine. More and more power has been squeezed out of smaller and more economic engines. One of the reasons is that in the last few years sensors have been developed which allow investigations to be made of the way in which the flame front spreads inside a cylinder after ignition. This work has led to a redesign of the geometry of the inlet valves and the piston, and more efficient engines are the result. The process of instrumentation is often considered solely in terms of the sensors used and their associated electronics. However, there are two steps involved in making any measurement. These are, first, getting the data, which is where sensors and electronics are used, and second, analysing it."
