investigation, the influence of numerous agents on the chromaffin cells was determined by a method of auto-assay which depended n the abilities of intra-aortic injections of these drugs to produce cardiovascular manifestations of epinephrine discharge. Synchronous recordings of heart force, pulse pressures

Abstract: Water and sediment samples were collected seasonally from nine stations along Alexandria coasts to determine the distribution of the bacterial groups which were able to produce antimicrobial agents and studying the correlations between their counts and the prevailing physico

Abstract: Diesel oil impacted tropical soil was screened for the presence of surface-active agent producing bacteria using the Drop-collapse, the red blood cell haemolysis test and the slide test. The total viable bacteria 4 5 5 5

generalizing function approximator such as a neural net. Although this has been successful in the domain of backgammon, there is no guarantee of convergence. In this paper, we show that the combination of dynamic programming and function approximation is not robust, and in even very benign cases, may produce

The next article in our series is one of the first reports from Hans Selye, who pioneered research on biological effects of exposure to stressful stimuli. This article is a cornerstone of neuropsychiatry because it led to the study of the effects of stress and hormones, particularly corticosteroids, on brain function. Hans Selye (1907–1982), a native of Hungary, founded

The resistance to infection of the tissues of the mouth greatly impressed early workers, who suspected an antibacterial action of saliva and devised experiments to investigate this possibility. (For complete references see Thompson, 1940.) Up to 1934 the results obtained were indecisive, and there was disagreement as to the presence or importance of such antibacterial action. In 1934 and suc-

The construction of large-scale embedded software systems demands the use of design methodologies and modelling techniques that support abstraction, inheritance, modularity, and other mechanisms for reducing complexity and preventing error. If multi-agent systems are to become widely accepted as a

This paper presents a novel approach to the problem of action selection for an autonomous agent. An agent is viewed as a collection of com- petence modules. Action selection is modeled as an emergent property of an activation/inhibition dynamics among these modules. A con- crete action

, hiding and recursion. We present a simple model for this language based on the specification-oriented methodology of [OH86]. The crucial insight is to focus on observing the resting points of a process—those stores in which the pro-cess quiesces without producing more information. It turns out

. The minimum inhibition concentrations "MICs " of the purified antifungal agent were also determined. In conclusion, the collected data emphasized the fact that the purified antifungal agent was suggestive of being belonging to 4 ' phenyl-1-napthyl-phenyl acetamide antibiotic produced
