A. S. G. CURTIS "Decompression and Narcosis"

Quotient G-systems and Green\'s Relations

In this paper, we first introduce the concepts of G-systems, quotient G-systems and isomorphism theorems on G-systems of n-ary semihypergroups . Also we consider the Green's equivalences on G-systems and further in-vestigate some of their properties. A number of n-ary semihypergroups are constructed and presented as examples in this paper.

This paper presents the METAXPath data model and query language. METAXPath extends XPath with support for XML metadata. XPath is a specification language for locations in an XML document. It serves as the basis for XML query languages like XSLT and the XML Query Algebra. The METAXPath data model is a nested XPath tree. Each level of metadata induces a new level of nesting. The data model separa...

Carbon Dioxide, Narcosis,

Carbon dioxide (CO2) is the gaseous end product of the aerobic metabolism of oxygen. CO2 is highly soluble in body tissues, and readily diffuses from cells to blood, where circulation transports it to the lungs for elimination. Divers often ignore carbon dioxide, as CO2 is a normal part of life. However, CO2 may have definite and detrimental effects if a diver accumulates an excessive amount of...

Avertin Rectal Narcosis

Tiif, rectal route for anaesthesia has been long under consideration. The first efforts in this direction were made by F. Roux in1846. The undeniable advantages of the rectal route, the easiness of administration, the avoidance of choking and excitation, and freedom from complications, opened up the way for further research. Injury to the bowel wall was the great danger in the experiments of Ro...
