    Notes: Abstract. A methodology is presented that explores soil survey information at the national level (1:1 M), generating sustainability indicators for wheat cultivation in Uruguay. Potential yields were calculated for simplified crop production situations under several constraints, such as limitation of water availability calculated from soil physical properties and climatic conditions, and limitation of nutrient availability calculated from soil fertility and climatic conditions. Land quality sufficiency was examined by comparing these yields with the constraint-free yield conditioned only by solar radiation, temperature and the crop's photosynthetic properties. Crop growth was simulated only for areas suitable for the defined agricultural use. Model runs were repeated with inclusion of a topsoil loss scenario over 20 years as defined from an erosion risk analysis. Comparison between crop growth simulations for the two situations, gives an indication of the changes in land quality status, which supplies an indicator for agroecological sustainability.On the basis of crop growth simulation it is concluded that wheat production constraints in Uruguay appear to be mainly related to water availability limitations, while nutrient availability is near optimal for the suitable soils. The simulated loss of topsoil impacts most on soil physical properties, expressed in reduced water-limited yields. Soil fertility status, evaluated by change in nutrient-limited yields, was little affected by the scenario.

    Notes: The influence of bite size on sensory mouthfeel and afterfeel sensations was explored in two studies in which single bites of vanilla custard desserts were varied from itollmL (study 1) and in which series of five bites of two different custard desserts were presented consecutively (study 2). In single bites, sensations of perceived creaminess were enhanced with size whereas sensations of astringency and temperature were suppressed. Bite size also affected perceived thickness, but the direction of the effects varied with custard desserts. With multiple bites, creaminess sensations continued to increase, whereas other sensations were unaffected. Switching to a second series of bites of another vanilla custard dessert showed larger sensory effects, especially on astringency sensations but also to a lesser extent on sensations of thickness and fatty afterfeel. Single and multiple bite results are discussed in terms of possible peripheral mechanisms. Switching results are discussed in terms of possible central sensory contrast mechanisms.

    Stimulating the Potential: Creative Performance and Communication in Innovation Teams (2004)

    Notes: Creativity is essential to successful new product development efforts. Teams constitute the organizing principle in most modern innovation activities. Although creativity research has revealed many factors influencing individual creativity, little is known about how team-level creativity is determined. Since the creative innovation task requires teams to combine and integrate input from multiple team members, the team's communication pattern is an important determinant of team creativity. Based on a sample of 44 NPD teams in eleven companies, this study examines the effects of team-member communication on team creativity. It is found that both interaction frequency and subgroup-formation of communication have a negative relationship to team creativity. Theoretical and practical implications are discussed, and further research is indicated.

    Predictive Analysis of Cocoa Procyanidins Using Near-Infrared Spectroscopy Techniques (2003)

    Notes: A near-infrared reflectance (NIR) spectroscopy technique for the prediction of procyanidins in cocoa beans (Theobroma cacao) has been developed. A select group of cocoa liquors from different origins used for the manufacture of chocolate were analyzed to determine quantitative levels of procyanidin oligomers (monomer to decamer) using normal-phase high-performance liquid chromatography. The calibration set included seasonal, environmental, and fermentation variations to cover the concentration range of procyanidins found at naturally occurring levels. The sample set was analyzed on FOSS NIR System II 6500 spectrophotometers and partial least-squares algorithms developed. Very good calibration statistics were obtained for the prediction of the total procyanidin oligomers (r2 = 0.983) with standard deviation/standard error of cross validation ratio (SD/SECV) of 5.68. A global version of this calibration, involving 20 Foss instruments produced a calibration r2 = 0.98 with a SD/ SECV = 6.20. Procyanidins have attracted increasing attention because of the rapidly growing body of evidence associating these compounds with a wide range of potential health benefits. A rapid method for the analysis of procyanidins in cocoa liquors would be beneficial in quality-control environments and would provide cost benefits to manufacturing operations.

    Notes: Let X be a zero-dimensional first category absolute Borel set of ambiguous class two. Then X can be given the structure of a topological group if and only if X is homogeneous and X=X x X. Thus, within the ambiguous class two, zero-dimensional groups only occur at the low levels, and the indecomposable levels of the hierarchy of difference classes DαΣ02 in 2ω.

    Quantitative analysis of bacterial communities from Mediterranean sapropels based on cultivation-dependent methods (2004)

    Topics: Biology
    Notes: Microbial communities of ancient Mediterranean sapropels, buried sediment layers of high organic matter, were analyzed by most probable number (MPN) approaches. Mineral media containing different carbon sources in sub-millimolar concentrations were used. MPN numbers were elevated in sapropels and at the sediment surface, which mirrored total cell count distributions. Highest MPN counts were obtained with a mixture of different monomeric and polymeric substrates, with amino acids or with long-chain fatty acids as sole carbon sources. These values reached up to 2 × 107 cm−3, representing 3.3% of the total cell count. A total of 98 pure cultures were isolated from the highest positive dilutions of the MPN series, representing the most abundant microorganisms culturable by the methods used. The strains were identified by molecular biological methods and could be grouped into 19 different phylotypes. They belonged to the α-, β-, γ-, and δ-Proteobacteria, to the Actinobacteria and the Firmicutes. However, about half of the number of isolates was closely related to the genera Photobacterium and Agrobacterium. Regarding the high cultivation success, these organisms can be assumed to be typical sapropel bacteria, representing a substantial part of the culturable indigenous microbial community.

    Distributions of microbial activities in deep subseafloor sediments (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-25
    Description: Diverse microbial communities and numerous energy-yielding activities occur in deeply buried sediments of the eastern Pacific Ocean. Distributions of metabolic activities often deviate from the standard model. Rates of activities, cell concentrations, and populations of cultured bacteria vary consistently from one subseafloor environment to another. Net rates of major activities principally rely on electron acceptors and electron donors from the photosynthetic surface world. At open-ocean sites, nitrate and oxygen are supplied to the deepest sedimentary communities through the underlying basaltic aquifer. In turn, these sedimentary communities may supply dissolved electron donors and nutrients to the underlying crustal biosphere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉D'Hondt, Steven -- Jorgensen, Bo Barker -- Miller, D Jay -- Batzke, Anja -- Blake, Ruth -- Cragg, Barry A -- Cypionka, Heribert -- Dickens, Gerald R -- Ferdelman, Timothy -- Hinrichs, Kai-Uwe -- Holm, Nils G -- Mitterer, Richard -- Spivack, Arthur -- Wang, Guizhi -- Bekins, Barbara -- Engelen, Bert -- Ford, Kathryn -- Gettemy, Glen -- Rutherford, Scott D -- Sass, Henrik -- Skilbeck, C Gregory -- Aiello, Ivano W -- Guerin, Gilles -- House, Christopher H -- Inagaki, Fumio -- Meister, Patrick -- Naehr, Thomas -- Niitsuma, Sachiko -- Parkes, R John -- Schippers, Axel -- Smith, David C -- Teske, Andreas -- Wiegel, Juergen -- Padilla, Christian Naranjo -- Acosta, Juana Luz Solis -- New York, N.Y. -- Science. 2004 Dec 24;306(5705):2216-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ocean Drilling Program Leg 201 Shipboard Scientific Party, NASA Astrobiology Institute, University of Rhode Island Graduate School of Oceanography, South Ferry Road, Narragansett, RI 02882, USA. dhondt@gso.uri.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15618510" target="_blank"〉PubMed〈/a〉
