In order that the differentiated tissues and organs of the multicellular body should produce an integrated response to the needs of the organism as a whole their activities must be controlled, or regulated. Regulation is by chemical means. In animals there are two distinct means of deliving these chemical regulators.

Organisational systems and their coordination
2020Organisational systems come in many different formats and ownerships. The essential characteristic of any system is that it must have a system purpose which it exists to fulfil. For organisational systems, the various components, that is the people working in the system, must know and understand what that purpose is and their role in its fulfilment ...

The UN system, which has been designed as an association of loosely connected organizations, requires considerable co-ordination efforts to limit overlapping, duplication and friction. The coordination in the UN system takes place at three different levelswithin member states, between member states, and between organizations.

Abstract : Numerical grid generation has been an excellent tool for producing curvilinear body-fitted coordinate systems. Curvilinear coordinate systems or grids are commonly used in the solution of partial differential equations in domains surrounding arbitrary geometrical boundary shapes.

Stratigraphic coordinate system
SEG Technical Program Expanded Abstracts 2011, 2011Seismic image flattening plays an important role in both interpretation and processing of seismic data. We introduce a new algorithm for seismic image flattening. The algorithm transfers seismic data to a new coordinate system and consists of two steps.

Coordinate Systems and Systems of Equation
2011A device simulator for nanoscale strained SiGe double gate PMOSFETs based on the self-consistent solution of the 1D SE, 2D PE, and multi subband 1D BTE is developed, which is applicable for arbitrary crystallographic orientations and arbitrary channel directions.

Coordinate Systems and Vectors
2000Coordinates and vectors—in one form or another—are two of the most fundamental concepts in any discussion of mathematics as applied to physical problems. So, it is beneficial to start our study with these two concepts. Both vectors and coordinates have generalizations that cover a wide variety of physical situations including not only ordinary three ...

Coordinate Systems and Vectors
2021This chapter introduces the various types of coordinate systems that exist in three dimensions and develops the basic concept of ‘metric’ to describe their properties. It introduces vectors in these coordinate systems and develops the notions of the ‘index language,’ dependence on the metric, and the covariance of vectors.

GPS satellites orbit the earth over time. GPS surveys are conducted mostly on land. To describe the GPS observation (distance) as a function of GPS orbit (satellite position) and the measuring position (station location), suitable coordinate and time systems must be defined.
