1. Kinematics of Mechanism: the study of motion without regard to forces That is about motion of the components and the basic geometry of the mechanism, and is not concerned with the forces which cause or affect the motion all the components of the mechanism are, in general considered rigid member 2. Kinetics or Dynamics of Mechanisms: the study of forces on the system in motion

1. What is Pathology: （1) Scientific study of diseas Causes (etiology) mechanisms (pathogenesis) （ 2)Investigation manifestaticn morphology of progress

drogen peroxide is formed in the cells of plants and animals but is toxic to them. neemen Consequently, living systems hav developed mechanisms to rid themselves of hydrogen peroxide, usually by enzyme-catalyzed reduction to water. An under- standing of how reactions take place, be they reactions in living systems or reactions in

Interactions within a package system refer to the exchange of mass and energy between the packaged food, the packaging material and the external environment. Food-packaging interactions can be defined as an interplay between food, packaging, and the environment, which produces an effect on the food, and/or package (Hotchkiss, 1997). Mass transfer processes in packaging systems are normally referred to as permeation, migration and absorption(fig8.1). Permeation is the process resulting from two basic mechanisms

Chapter 5 Macromolecules and Molecular Genetics The key informational macromolecules in prokaryotic and eukaryotic cells are DNA, RNA, and protein. Molecular Genetics deals with the mechanisms by which the information in DNA is replicated, and by which it can be transcribed into rNa and translated into specific proteins
