TL;DR: In this paper, an integrated series of operations research studies directed toward improvement in such scheduling methods is presented. But the focus is on essentials of the mathematical model and other phases of the OR studies are brought in only as required.
Abstract: Scheduling heating oil production is an important management problem. It is also a complex one. Weather and demand uncertainties, allocation of production between different refineries, joint-and by-product relations, storage limitations, maintenance of minimal supplies and many other factors need to be considered. This paper is concerned with one of an integrated series of operations research studies directed toward improvement in such scheduling methods. Emphasis is on essentials of the mathematical model. Institutional features and other phases of the OR studies are brought in only as required.

TL;DR: An analytical model of a continuously fed, completely mixed Chlorella culture in which light is the factor limiting growth is presented and it is found that in a culture of this type the population density is directly proportional to the retention time and the production rate is independent of retention time.
Abstract: An analytical model of a continuously fed, completely mixed Chlorella culture in which light is the factor limiting growth is presented. The conclusions from the theory are that in a culture of this type the population density is directly proportional to the retention time and the production rate is independent of retention time. Experimental data are presented to verify the theoretical conclusions.

TL;DR: Since the semiradical o-(S) of a semiring S is contained in every semimaximal semimodular left ideal L, this implies that u(S)S < a (S) < L, hence a(P) < PL, and it is shown if r ¢ v(S), then there exists a semiprimitive ideal P such that r f P.
Abstract: THEOREM 8. The semiradical of a semiring is the intersection of the semiprimitive ideals. Proof: Since the semiradical o-(S) of a semiring S is contained in every semimaximal semimodular left ideal L, this implies that u(S)S < a(S) < L, hence a(S) < PLConversely, we shall show if r ¢ v(S), then there exists a semiprimitive ideal P such that r f P. By Lemma 10 (left and right interchanged) we know that rS f a(S) and thus there exists an element x of S such rx f a(S). By Theorem 7 there exists a semimaximal semimodular left ideal L such that rx f L. This implies that r f PL.
