    Abstract: Population growth in the coming decades will put severe pressure on human food, animal feed, and fiber production from both land and ocean ecosystems.℗ Environmental sustainability and social justice are increasingly important elements in debates on how to ensure adequate food for a℗ growing global population.℗ Gathering approximately 90 peer-reviewed entries from the Encyclopedia of Sustainability Science and Technology, Sustainable Food Production provides comprehensive coverage of this vital area of current research.℗ Sections on animal breeding and genetics for food, crop science and technology, ocean farming and sustainable aquaculture science and technology, and transgenic livestock for food discuss state-of-the-art scientific advances, and place them in their proper scientific, environmental, ethical, socio-economic, and political contexts

    Notes: Abstract Nonrelativistic and quasirelativistic energy-adjusted pseudopotentials and optimized (7s6p5d)/[5s4p3d]-GTO valence basis sets for use in molecular calculations for fixed f-subconfigurations of the rare earth elements, La through Lu, have been generated. Atomic excitation and ionization energies from numerical HF, as well as SCF pseudopotential calculations using the derived basis sets, differ by less than 0.1 eV from numerical HF all-electron results. Corresponding values obtained from CI(SD), CEPA-1, as well as density functional calculations using the quasirelativistic pseudopotentials, are in reasonable agreement with experimental data.

    Notes: Summary Kinetics of the UV-induced (λ=254 nm) inactivation of phage MS2 is studied for stirred and non-stirred solutions with optical densities ranging from 0.06 to 2.1. The extent of inactivation exhibits exponential dependence on irradiation time for stirred solutions thus indicating the homogeneity of the phage population in respect to photosensitivity of infectivity. Irradiation of the same solution without stirring results in deviation of survival curves from exponential ones (the so called “tailing”), being more pronounced the larger the optical density of the layer under irradiation and degree of inactivation. Such a deviation is conditioned by non-uniform light absorption by virions in solution in the absence of stirring. The inactivation kinetics upon UV-irradiation of the stirred and non-stirred phage solutions is rather accurately expressed by respective equations thus enabling the choice of rational conditions for a given depth of phage inactivation to be performed.

    Notes: Abstract Four density functionals — including that recently introduced by Perdew ((1986) Phys Rev B33: 8822)—are tested for first-row atoms, hydrides and dimers. Calculated contributions of the correlation energy to the ionization potentials and electron affinities of atoms and to the dissociation energies of molecules are compared with “empirical” values which were reevaluated for this purpose. An improvement over Hartree-Fock is found in all cases if the self-interaction or the gradient correction are included in the density functional, although there is a rather large variation in the accuracy of the predictions.

    Notes: Abstract A short description of the SAS (subsatellite analyser of spectra) wave experiment on board the Magion-4 subsatellite is given. We present first measurements of the magnetic-field fluctuations in the frequency range 32–2000 Hz obtained in the magnetotail during the disturbed period at the magnetopause and in the polar cusp.

    Notes: Abstract The plasma-wave experiment ASPI (analysis of spectra of plasma waves and instabilities) on board the INTERBALL spacecraft is a combined wave diagnostics experiment. It performs measurements of the DC and AC magnetic field vector by flux-gate and searchcoil sensors, the DC and AC electric field vector by Langmuir double probes and the plasma current by Langmuir split probe. Preliminary data analysis shows the low noise levels of the sensors and the compatibility of new data with the results of previous missions. During several months of in-orbit operation a rich collection of data was acquired, examples of which at the magnetopause and plasma sheet are presented in second part of the paper.

    Notes: Summary Two physiological characteristics of butyric fermentation, inhibition by the acids produced, butyrate and acetate, and dependence on the growth rate of the distribution of these acids, prompted a study of butyrate production in a continuous fermentation system with cell recycle by microfiltration. The influence of the main operating parameters, glucose input (feed concentration and dilution rate) and bleed dilution rate on production of acids and biomass was studied. The performance of the system greatly exceeded the results obtained in batch and simple continuous fermentations as a high productivity for butyrate (9.5 g l−1 h−1) was achieved whilst retaining a satisfactory concentration of butyrate (29.7 g l−1) and low acetate production (0.6 g l−1) at a cell biomass concentration of 35 g l−1. Cell growth rate was found to be a critical parameter for performance stability as oscillations in metabolic activity due to inhibition by acids were observed at bleed dilution rates below 0.016 h−1.

    Notes: Summary The parameters that control fermentation performance of butyrate production have been studied with a selected strain ofClostridium tyrobutyricum. Fed-batch supply of glucose increased productivity for butyrate. The ratio of butyrate to total acids was strongly influenced by the growth rate of the bacteria, acetate being produced along with butyrate at higher growth rates. In glucose-limited, fed-batch cultures, initially produced acetate was re-utilized, resulting in exclusive production of butyrate. In cultures with non-limiting glucose feeding, the butyrate concentration reached 42.5 g·1−1 with a selectivity of 0.90, a productivity of 0.82 g·−1 per hour and a yield of 0.36 g·g−1 The effects of the mode of supply of glucose on the production of butyrate and acetate are discussed in relation with the energy requirements for cell growth.

    Notes: Summary Production of butyrate has been studied in continuous cultures of Clostridium tyrobutyricum. Production of acids, gases and cell biomass were determined under conditions of glucose limitation by varying either the glucose input or the dilution rate. Addition of acetate or butyrate to the cultures was also tested. The results led to the proposition that inhibition by acids acting as incouplers of energy production could provide a physiological explanation for most of the phenomena observed. It readily accounted for the higher productivities but lower product concentrations obtained in continuous culture with respect to batch or fed-batch conditions. It also explained the decrease in the ratios of butyrate to total acids and in cell yield observed at higher glucose input as well as the behaviour of the cultures under conditions of excess glucose. It could also possibly account for the partial conversion of added acetate to butyrate observed at moderate growth rates.
