Product development has been a major activity in the food industry for over 40 years, but only gradually has it developed as a strategic business area and also as an advanced technology. For a long time it was essentially a craft, loosely related to the research and engineering areas in the company. The pressures for product development came very strongly from the needs of the growing supermarkets for a constantly changing, extensive mix of products and for continuous price promotions. So there was the drive for product difference

In this chapter we will extend the concepts which have been presented in the preceding chapter so as to develop general methods of phasor analysis for circuits which are under conditions of sinusoidal steady-state excitation. The methods are very similar to those for resistance circuits which were presented in Chap.2

An ideal transformer is a useful approximation of a very tightly coupled transformer in which the coefficient of coupling is almost unity and both the primary and secondary inductive reactance are extremely large in comparison with the terminating impedance

One of the main uses of Thevenin's and Norton's theorems is the replacement of a large part of network very simple equivalent

Overview: As you may discover, growing single crystals takes patience as well as an artful hand Crystallizations can be very sensitive to temperature and minor disturbances. Therefore, you will be encouraged to try several different temperatures using otherwise identical conditions, and to always find a quiet undisturbed location to promote crystal growth. Here are some tried and true tips to get

In lecture D9, we saw the principle of impulse and momentum applied to particle motion. This principle was of particular importance when the applied forces were functions of time and when interactions between particles occurred over very short times, such as with impact forces. In this lecture, we extend these principles to two dimensional rigid body dynamics. Impulse and Momentum Equations Linear Momentum In lecture D18, we introduced the equations of motion for a two dimensional rigid body. The linear momen- tum for a system of particles is defined

In the previous lecture, we related the motion experienced by two observers in relative translational motion with respect to each other. In this lecture we will extend this relation to our third type of observer.That is, observers who accelerate and rotate with respect to each other. As a matter of illustration, let us consider a very simple situation, in which a particle at rest with respect

Histones vs Nonhistone Histones are small, very basic proteins rich in lysine and arginine. The histones are the basic building blocks of chromatin structure. The nucleoids of prokaryotic cells also have proteins associated with DNA, but these proteins are quite different from the histones and do not seem to form a comparable chromatin structure. Nonhistone chromosomal proteins-The histones are accompanied

This equation accounts for the kinetic data given in Figure 8-15.At very low substrate concentration, when [S] is much less than KM, V [s]Vmax/KMi that is, the rate is directly proportional to the substrate concentration At high substrate concentration, when [SI is much greater than KM, V=Vmax; that is, the rate is maximal, independent of substrate

Tomato powder is much in demand by dehydrated soup manufacturers, and is now produced in many countries where tomatoes are an indigenous outdoor crop. The heavy cropping Italian plum tomato is ideal for drying down to powder, and this is grown in most areas with a 'Mediterranean- type' climate. Tomatoes have a very low solids content-not more than 6 percent- and dehydration must be preceded by evaporating the pulped
