  • We have adopted a number of conventions in this book in order to maintain a consistent, clear, and identifiable notation. As far as possible we have kept to common conventions for symbols and quantities in quantum chemistry. We have also tried to avoid the duplication of symbols where possible. These goals conflict to some extent, so some quantities are given unconventional symbols. The following list identifies symbols and typography used throughout the book.

  • The requirements for discharging known or highly-suspected multi-drug resistant TB (MDRTB) patients are more stringent. Since the number of new MDRTB patients in NYC has decreased by over 90% since 1992, the likelihood that a patient whose susceptibility results are not yet available upon discharge will have MDRTB is very small. The NYC Department of Health and Mental Hygiene (DOHMH) maintains an excellent infrastructure of ambulatory care clinics to diagnose and treat TB patients and to provide supporting services such as DOT, all free of charge to the patient.

  • Chapter 17 - The mechanism of translation I: Initiation. This chapter concerns the initiation of translation in eukaryotes and bacteria. Because the nomenclatures of the two systems are different, it is easier to consider them separately. Therefore, let us begin with a discussion of the simpler system, initiation in bacteria. Then we will move on to the more complex eukaryotic scheme.

  • Electric charge and a measure for the quantity of charge Any household electrical appliance – be it a light bulb, a motor, or a television set – has two contacts which have to be plugged in to get the device to operate. This common characteristic, that an electrical apparatus must have two wires connecting it to a source of electricity, gave the rise in the eighteenth century to the idea that when an electrical device is working, something is moving through it. That something is called electric charge. When you pull out a plug, turn off a switch, or disconnect...

  • 1.1 The balance of charges on conductors: In conductors there are charged particles which can be freely move under any small force. Therefore the balance of charges on conductors can be observed under these circumstances:  The electric field equals zero everywhere inside the conductor E = 0 The electric potential is constant inside the conductor V = const  The electric field vector on the surface of conductors direct along the normal of the surface at each point E = En The surface of conductors is equipotential Inside conductors there is no charge.

  • We have known how can describe the electric field in vacuum. How is the electric field in a matter environment? In this chapter we consider the case that the environment is a nonconducting material Recall that in a conducting body (conductor) the charges move freely in respond to an electric field, but in nonconducting bodies the charges can not move freely. Nonconducting bodies are called dielectrics or insulators.

  • Replicability requires the consideration of sustainable ways by which services can be provided to unserved populations across a particular coun- try. To provide a sustainable level of service will, in some cases, require significant reforms: financial reforms at the sector level, reforms of bud- getary systems, reforms in subsidy levels, reforms of user charges, and so on. This is a tough menu of reforms to be carried out by social funds; indeed, social funds cannot undertake reforms of this extent.
