Figure 3.8 Selectable markers. Formation of recombinant plasmid DNA (pDNA) constructs (see Figs 3.6 and 3.7) is not 100% ef cient such that recombinant and cloning vector pDNA (without heterologous DNA restriction fragment insert) co-exist at the end of the process. Also, host bacterial transformation is not 100% ef cient either so that both transformed and non-transformed bacteria co-exist post-transformation. Both of these problems are solved by growth and selection. Bacterial growth is performed in the presence of antibiotic (antibiotic selection) on agar culture plates so that only transformed bacteria (1 pDNA/cell) can survive and give rise to observed colonies. Individual colonies must then be selected for further analysis of pDNA sequence to check for the presence of recombinant versus cloning vector pDNA. The lac Z selection process allows for the presence of recombinant versus cloning vector pDNA to be determined more directly on the basis that the lacZ function is disrupted in recombinant pDNA constructs and not in clonal vector pDNA. Hence if X-gal is included in the agar, only bacterial colonies that harbour cloning vector pDNA should develop a blue colour while those that harbour recombinant pDNA constructs should be white in colour. Individual white colonies can then be selected for further analysis of pDNA sequence. Three main selectable marker antibiotics are shown. X-gal and the effect of -galactosidase ( -gal) on X-gal are also illustrated.

Practical calculations in any field theory employ a regularization procedure that sets a length scale below which processes have no influence on the theory. For example, we saw that in calculating QED loop diagrams the divergent integrals could be cut off at some momentum k, rendering them finite (56.4). In effect, the cutoff momentum defines a length scale L N O ( k - l ) below which phenomena make no contribution to the field theory. The lattice spacing plays a similar role since space and time are defined only at discrete lattice points. Like the momentum cutoffs for loop integrals, this length scale must disappear in the final theory: the lattice spacing is only an artifact to facilitate calculations; in a correct theory, no physical quantity may depend on it. Thus, a lattice is intended to play the same role that a discrete mesh plays on a computer in solving differential equations. However, the requirements of Lorentz invariance, gauge invariance, the Pauli principle for fermions, and consistency with perturbatively renormalized solutions make a lattice gauge calculation much more difficult than an ordinary numerical calculation. A lattice theory is well defined as long as one is on the lattice: there is no infinite renormalization on a finite lattice because the lattice spacing provides an ultraviolet momentum cutoff. It is only when we attempt to recover the physical continuum limit that the question of a smooth joining to (renormalized) perturbative results becomes important. In addition, we will see that it is possible to formulate gauge theories on a lattice without the gauge-king requirements of the continuum path integral theory, basically because gauge elements on a lattice vary over a compact group manifold (Wilson, 1974). There are two general methods for implementing gauge theories on lattices. In the Lagrangian formulation the theory is constructed on a Cdimensional spacetime lattice (Wilson, 1974). This approach is also often termed Euclidian, because as a practical matter the actual calculations are done in Euclidian Qspace after an analytical continuation from Minkowski space. In an alternative approach only space is discretized, time is treated as a continuous variable, and there is no rotation to Euclidian space. This is called the Hamiltonian formulation of lattice gauge theory (Kogut and Susskind, 1975). For much of our discussion we will focus on the Lagrangian method, primarily

Since the introduction of Flash, one of its most exciting effects has been the wealth of dynamic capabilities that it has brought to the Web. Flash 4 expanded our horizons by enabling users to actively participate in the Web experience. With this expansion of capability, it s no wonder that there has been an explosion of Flash games on Web sites and distributed in our e-mails as Projector files. Now that Flash 5 has increased our available tools exponentially, I think we ve only seen the tip of the iceberg. This tutorial helps you make a little ice. It takes you systematically through a nontechnical analysis of architecting a game using a case study, followed by a technical look at how Flash 5 helps solve some of the challenges this case study presents. The source .FLA and other assets relevant to this tutorial can be found in the ch22 folder of the CD-ROM.

Normally, when the user right-clicks in a worksheet, a shortcut menu appears. If, for some reason, you want to prevent the shortcut menu from appearing, you can trap the RightClick event. The following procedure sets the Cancel argument to True, which cancels the RightClick event and, thus, the shortcut menu. Instead, a message box appears.
