ENZYMES ARE HIGHLY SPECIFIC Enzymes are highly specific both in the reaction catalyzed and in their choice of reactants, which are called substrales. An enzyme usually cata- lyzes a single chemical reaction or a set of closely related reactions. Side

3.1 Preface 1. data object--- a set of instances or values for example: Boolean={ false,true} Digit={0,1,2,3,4,5,6,7,8,9} Letter={A, B, ....., a,b, ..... Z} NaturalNumber= {0, 1,2, ..... Integer={0,+1,-1,+2,-2,+3,-3,} String={a,, ..... ,aa, ab, ac

In addition to the equations of linear impulse and momentum considered in the previous lecture, there is a parallel set of equations that relate the angular impulse and momentum. Angular Momentum We consider a particle of mass, m, with velocity v, moving under the influence of a force F. The angular momentum about point O is defined as the \moment\ of the particle's linear

A point at which two or more elements have common connection is called node(节点). Suppose that we start at one node in a network and move through a simple element to the node at the other..., if no node was encountered more than once, then the set of nodes and elements that we have passed hrough is defined as path(路径)

Product development management in the food system is complex, long term and capital intensive. It is total company management involving every function in the company- so it is managing either a microcosm of the company or an integration of the company functions. For a major innovation, the company may set up a new venture company or division; or a new group of people may form a new company. At this time when many new companies are being formed on the innovations of information technology and biotechnology, it is interesting to speculate on new venture companies in the food industry and the basis of their new innovations. But at the present time

If a set of random variables X, having the multidimensional normal distribution is uncorrelated(the covariance matrix is diagonal, they are independent. The argument of the exponential becomes the sum over i of Thus, the distribution becomes a product of exponential

For general applications in 3D, often need to perform 3 separate rotations to relate our inertial frame to our body frame Especially true for aircraft problems There are many ways to do this set of rotations -with the variations be based on the order of the rotations All would be acceptable

1. Establish a normal tree. tree branches--Us, C(, R) cot ree(chords)-i,,(, R) 2. Assign voltage and current variables. Assign a voltage (with polarity reference) to every capacitor and a current(with arrow) to every inductor; there are the state variables. Indicate the voltage across every tree branch and the current through every link in terms of the source voltages, source currents,and the state

You are asked to set off from any piece of the lands and pass through all the seven bridges under the condition that each bridge can be used only once, so that you can finally return to the starting point
