Formiminoglutamic acid is a product derived from the metabolism of histidine by mammalian liver and several microorganisms (l-3). The metabolism of FGA’ is dependent upon the presence of tetrahydrofolic acid (4, 5), and consequently this formimino compound is excreted in the urine of human subjects or laboratory rats which have a deficiency of folic acid (6-8). Daft (6) has reported that suitab...

A monoid S satisfies Condition (A) if every locally cyclic left S-act is cyclic. This condition first arose in Isbell’s work on left perfect monoids, that is, monoids such that every left S-act has a projective cover. Isbell showed that S is left perfect if and only if every cyclic left S-act has a projective cover and Condition (A) holds. Fountain built on Isbell’s work to show that S is left ...

Recent growth in the renewable energy industry has increased government support for alternative energy. In the United States, hydropower is the largest source of renewable energy and also one of the most efficient. Currently, there are 30,000 megawatts of potential energy capacity through smalland micro-hydro projects throughout the United States. Increased development of micro-hydro could doub...

The Command and Control theory of John Boyd, a 20 century military strategist, allow us to introduce computing techniques that are able to speed up the OODA loop (Observe–Orient–Decide–Act), especially on observing and orienteering steps. This paper introduces a low cost framework capable of monitoring people, vehicles, boats, or any other elements of interest, almost in real time. The goal of ...

In Driessen (1986) it is shown that for games satisfying a certain condition the core of the game is included in the convex hull of the set of certain marginal worth vectors of the game, while it is conjectured that the inclusion holds without any condition on the game. In this note it is proved that the inclusion holds for all games. Zusammenfassung: In Driessen (1986) wurde for Spiele, die ei...
