Profit planning

"10/77/1.5M""This manual discusses some practical uses of break-even analysis in foodservice operations. It does not present the complete application of the use of the break-even system. This manual is designed primarily to make foodservice operators aware of the break-even concept as an effective managerial tool for profit planning."--First paragraph.Robert F.

Kleiss-Kuijf relations from momentum amplituhedron geometry

44 pages, 19 figuresAbstract: In recent years, it has been understood that color-ordered scattering amplitudes can be encoded as logarithmic differential forms on positive geometries. In particular, amplitudes in maximally supersymmetric Yang-Mills theory in spinor helicity space are governed by the momentum amplituhedron. Due to the group-theoretic structure underlying color decompositions, color-ordered amplitudes enjoy various identities which relate different orderings. In this paper, we show how the Kleiss-Kuijf relations arise from the geometry of the momentum amplituhedron. We also show how similar relations can be realised for the kinematic associahedron, which is the positive geometry of bi-adjoint scalar cubic theory.Peer reviewe

Restaurant site selection

"Restaurant site selection is a complex decision often made without proper planning or sufficient information. It is generally held that the site selection process is more art than science and therefore difficult to quantify. The most important aspect of site selection is to assure that all factors that could possibly have any bearing on the decision are considered carefully."--First paragraph.Neil P.

cGMP kinase I regulates glucagon release

© 2009 Leiss et al; licensee BioMed Central Ltd. Blood glucose levels are tightly controlled by the two peptide hormones glucagon and insulin. At hyperglycaemia, B-cells in the islets of Langerhans secrete insulin, whereas islet A-cells release glucagon at hypoglycaemia to stimulate e.g. glucose production in the liver. Previously, an important role for nitric oxide (NO) in the development of type-1 diabetes mellitus (insulin dependent diabetes mellitus) was reported [1]. The mechanisms are unknown whereby NO modulates islet (mal-)function. We hypothesized that NO signals via the cGMP/cGMP kinase I (cGKI) pathway to modulate the endocrine control of blood glucose levels. Glucose homeostasis was studied in the conventional cGKI knockouts (KOs) and in cGKI rescue mice (RM) [2] in comparison to age- and littermat
