Primary definition

Patients with brain metastases have a poor prognosis. Untreated patients generally have a median survival of 1 month. The choice of treatment depends primarily on the status of the patient s underlying malignancy and the number and sites of brain metastases. The primary definitive treatments for brain metastases are surgery and radiation therapy. Pharmacologic modalities are... 

In those infections that are associated with enteropathy (exemplified by T. spiralis), no experimental manipulation has, until recently, been able to separate enteropathy and immune expulsion - if one is abrogated, so is the other. This chapter illustrates how the two processes can be separated, and discusses implications of this for understanding immune expulsion of gut nematodes and the prospects for anti-nematode vaccines that cause no ill effects at either the initial induction of immunity or the expression of protective responses. The definition of that which consitututes enteropathy may vary between authors, but we take as our primary definition the most destructive and quantifiable changes in intestinal tissue that are associated with expulsion, villus atrophy and crypt hyperplasia.

There are two primary definitions for the term Network. One definition for a network describes a few computers with lots of terminals. Such installations frequently have grown from a batch environment with a large central mainframe computer to which terminals have been added. The term data communications is used to describe terminal (or terminal like) communications between the terminal and host. This is perhaps the most mature communications area. It was developed initially to support Teletype Equipment over telephone lines. 

The primary definition is the thermod5mamlc one (sec. 1.2.3), according to which the tension is the force per unit length needed to expand the area by an infinitesimal amount, isothermally and reversibly. It is typical for thermodynamic definitions that they are based on processes that in principle can be Ccirried out, i.e. they involve operational quantities. When the expansion cannot be carried out isothermally and reversibly it is impossible to define the interfacial tension operationally. This is for instance the case with solids (sec. 1.2.24) but also with monolayers in which expansion involves energy dissipation as a result of the irreversible breaking of bonds.

In terms of the primary definition of temperature which we have for the time being adopted, Charles s law, which states that gas pressure is proportional to the absolute temperature, would be a tautologous statement. It is not necessarily so, and was not so in its historical setting, since other scales of temperature, notably that based upon the expansion of a mercury column by heat, are possible. The mercury thermometer and the gas thermometer provide scales... 

Over time, the term engineering appears to have migrated from the primary definition, the application of science and mathematics by which the properties of matter and the sources of energy in nature are made useful to people toward a secondary definition, the design and manufacture of complex products, which focuses on the technical aspects of a solution. This migration has not helped the profession. It has separated designers and developers from users, created separate words...

The purpose of this first chapter is to orient the reader to the information provided in the handbook. There are eight chapters to the handbook with specific terms, acronyms and terminology pertinent to each section and the data contained therein. This chapter provides first an overview of the informational data base and discussions provided in each chapter, and second, it provides specific description of the terms pertinent to the eight reference chapters. The reader will find that some primary definitions are repeated in the chapters, however, in most cases, the reader will be referred either to this first chapter or the Glossary at the end of the handbook. 

It is absolutely vital for our discussion to have a good definition of a localized electronic state as opposed to one which is delocalized. The later will also be referred to as a quasi-free electron. Our primary definition will be that the localized electron is characterized by a wave function which decays exponentially with distance the same type of definition used for simple atomic wave functions. The quasi-free electron...
