• Parsons: Functional Imperatives , Structure of the General Action System and Pattern Variables • Merton: Clarifying functional analysis, Dysfunctions, and Manifest and Latent functions
Functional groups The structural features that make it possible to classify compounds by reactivity are called functional groups. A functional group is a part of a larger molecule and is composed of an atom or a group of atoms that have a characteristic chemical behavior. The Chemistry of every organic molecules
10.1 Introduction 10.2 Regulation can be negative or positive 10.3 Structural gene clusters are coordinately controlled 10.4 The lac genes are controlled by a repressor 10.5 The lac operon can be induced 10.6 Repressor is controlled by a small molecule inducer
Principal Aim To assess the strength changes, and associated change in fracture risk, due to structural alterations in the proximal femora of astronauts experiencing longterm weightlessness
