An automated apparatus to assist in the development of analytical continuous flow methods is described. The system is capable of controlling and monitoring a variety of pumps, valves, and detectors through an IBM PC-AT ...

Trends of rainfall in East Africa during the period 1922-1975 are examined using two independent approaches. namely the graphical and statistical methods. Under the graphical method the original and smoothed rainfall series ...

The in vitro synthesis of proline from glutamate was followed in fat body homogenates from the tsetse fly Glossina morsitans. Rates of synthesis were much higher in freeze-thawed or sonicated homogenate than in untreated ...

The capacity factors for the chromatographic retention of naphthalene, fluorene, phenanthrene and pyrene in supercritical carbon dioxide using an octadecyl silate bonded-phase column have been measured between 300 and 400 ...

The transonic integro-differential equation for two-dimensional flows is solved by boundary element methods. In addition to constant and quadrilateral elements we develop hybrid elements based on constant elements in the ...

This article deals with multistage group screening in which group-factors contain the same number of factors. A usual assumption of this procedure is that the directions of possible effects are known. In practice, however, ...

The phenomenon of growth is a widely applicable and investigative topic in various disciplines. An economist would study it in the light of demand and supply. A manager would like to study it as an organisational objective ...
