Food shortage in Sub-Saharan Africa is predominantly taken as a function of limited access to food, with out considering nutritional quality. Analyzing households’ production of nutrients on farm across farming systems could be valuable in guiding intensification of those systems. An optimization model was employed to analyze the scenario of human nutrition and cropland allocation in Enset (Ens...

Food shortage in sub-Saharan Africa is generally considered a function of limited access to food, with little thought to nutritional quality. Analyzing household production of nutrients across farming systems could be valuable in guiding the improvement of those systems. An optimization model was employed to analyze the scenario of human nutrition and cropland allocation in enset (Enset ventric...

The Security functionality provided by the protocols is almost equivalent. While the FTAM and RDA authentication and authorisation mechanisms are a mere mapping to those of the accessed file system or database, DFR defines own mechanisms. No sound statements on efficiency and reliability issues of the protocols can be made right now. These have to be derived from experiences with trial implemen...

Summary Reaction kinetics between calcite and acid systems have been studied using the rotating disk apparatus (RDA). However, simplifying assumptions made to develop current equations used interpret RDA experiments enable solving them analytically in contrast numerical methods. Previous work has revealed inadequacies of some these assumptions, which necessitates use a computational fluid dynam...

En 1977 se entablaron relaciones entre el SED, partido comunista gobernante en la RDA, y PSOE, socialdemócrata, que por entonces estaba oposición e iba a gobernar España partir de 1982. La necesidad RDA reforzar sus contactos con Occidente interés del PSOE dar una política exterior mirase hacia Europa Este sirvió para habilitar las interpartidistas un canal diplomático informal apoyo entendimie...

The representational difference analysis (RDA) and other subtraction techniques are used to enrich sample-specific sequences by elimination of ubiquitous sequences existing in both the sample of interest (tester) and the subtraction partner (driver). While applying the RDA to genomic DNA of cutaneous lymphoma cells in order to identify tumor relevant alterations, we predominantly isolated repet...

Understanding circuit function requires the characterization of component neurons and their neurotransmitters. Previous work on radula protraction in the Aplysia feeding circuit demonstrated that critical neurons initiate feeding via cholinergic excitation. In contrast, it is less clear how retraction is mediated at the interneuronal level. In particular, glutamate involvement was suggested, bu...

The 10th edition of Recommended Dietary Allowances (RDA) did not include an RDA for copper; rather a safe and adequate daily intake was suggested. Criteria, history and uses of RDAs were summarized along with data on dietary intakes, balance and depletion experiments, low (fats and oils, skim milk and yogurt) and high (legumes, mushrooms, nuts and seeds) copper foods and hazards of zinc supplem...
