  • Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structures

    Yield variability of spring pea (Pisum sativum L.) in farmers' fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and thus should be less sensitive to abiotic stress at the end of the cycle, but because of their sensitivity to frost they must be sown late in autumn when soils are very wet. Pea breeders are working on ...

  • Sowing the seeds of smarter transport policy

    Did we miss something? Last year, the European Commission didn’t propose a single new legislative measure to clean up transport. To be fair, it has been spending most of its time worrying about the future of the Eurozone. As a result, for T&E this was the sort of year where seeds for smarter transport policy were sown. We’re optimistic that next year could bring a decent crop of ...

  • How three U.S. mini-farms are sowing the seeds of global food security

    Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

  • Emergence of polymer-coated corn and soybean influenced by tillage and sowing date

    No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

  • Cooking under the sun

    A $6 cardboard box that uses solar power to cook food, sterilise water and could help 3 billion poor people cut greenhouse gases, has won a $75,000 prize for ideas to fight global warming.The 'Kyoto Box', named after the United Nations’ Kyoto Protocol that seeks to cut emissions of greenhouse gases, is aimed at billions of people who use firewood to cook.The cooker uses the greenhouse effect to ...

  • Sowing and flowering delays can be an efficient strategy to improve coexistence of genetically modified and conventional Maize

    The coexistence between genetically modified (GM) and non-GM maize (Zea mays L.) fields is subjected to regulation in several countries. A strategy to reduce cross-pollination from GM to non-GM fields was evaluated, on the basis of reducing the flowering coincidence by sowing at separate times. The trial included narrow plots in which transgenic maize was sown before, simultaneously, and after ...

  • Characterization of selected nutrients and bacteria from anaerobic swine manure lagoons on sow, nursery, and finisher farms in the Mid-South USA

    Received for publication October 31, 2008. Swine (Sus scrofa domestica) production in the Mid-South USA comprises sow, nursery, and finisher farms. A 2007 packing plant closure started a regional shift from finisher to sow and nursery farms. Changes in manure stored in lagoons and land-applied as fertilizer were expected but were unknown because nutrient and bacterial levels had not been ...

  • Goosegrass and Bermudagrass competition under compaction

    Goosegrass (Eleusine indica L.) is a serious weed in trafficked areas of bermudagrass (Cynodon spp.) golf and sports turf. The objective of this study was to evaluate soil compaction and canopy cover as determinants of goosegrass competition in bermudagrass turf in sand soil. Goosegrass cover, plant density, and soil penetration resistance (SPR) were measured in traffic and no-traffic plots in ...

  • Critical Operations Go Under Cover

    For a number of years, composting facilities have been using fabric structures to house finished compost screening, soil blending and product storage. They’ve also employed the structures to cover or fully enclose feedstock receiving and mixing. And some have gone as far as to put active composting operations inside fabric buildings. “More and more facilities are putting in fabric ...

  • Effect of sowing year and seedbed type on yield and yield component in bambara groundnut (Vigna subterranea (L) Verdc) in woodland savannahs of Cote d`Ivoire

    Bambara groundnut (Vigna subterranea) is one of the most promising food legumes in Africa, due to its agronomic and nutritional potential. To take advantage of these attributes, several research programmes gathering agronomic and genetic ...

  • Valuation and Management of Fishing Resources Under Price Uncertainty

    The traditional expected-net-present-value methods cannot properly capture the management flexibility and strategic value aspects of a fishery, and may understate its value. Instead, this paper develops a Real Options model to conceptualize and evaluate fishery exploitation flexibility. Specifically, general models to value the opportunity to either exploit or invest in a fishery are presented. ...

  • Consolidation Behavior of Clayey Soils Under Radial Drainage

    For Barron´s degree of consolidation, Ur, versus the time factor, Tr, relationship for soils undergoing consolidation with radial drainage for the equal vertical strain condition, a simple method has been developed to determine the value of the coefficient of consolidation with radial drainage, cr. Theoretical log10(d2e/t) versus Ur curves where de is the diameter of influence and t is the real ...

  • Employees' performance appraisal with TOPSIS under fuzzy environment

    Inadequate use of human resources is one of the main challenges facing the management sector these days. Employee is the primary foundation and impetus for organisation development, by understanding and evaluating employees correctly, the enterprise can impel employees effectively and guarantee the organisation's rapid and sustainable development. This paper establishes the more comprehensive ...

  • Looking Under the Hood at Toyota - What Went Wrong?

    This article is the third in a 3-part series that takes a closer look at the goings-on at Toyota - from the inside - as well as investigate further some of the claims that Toyota has made relative to its environmental achievements in light of the safety issues that ...

  • Swelling Pressure Behavior Under Controlled Suction

    An experimental study has been conducted to study the swelling pressure behavior of expansive soil in both vertical and lateral directions simultaneously under controlled suction. A series of one-dimensional consolidation tests was carried out on compacted soil specimen using a newly developed oedometer with devices for controlling suction and measuring lateral pressure. The test results show ...

  • Literature review of oil refineries planning under uncertainty

    This paper presents a literature review in the area of refinery planning models with emphasis on the main techniques to deal with optimisation under uncertainty. The studies are classified according to the segment of the oil chain (upstream, midstream, or downstream), planning level (strategic, tactical, or operational), and problem type (LP, NLP, MILP, or MINLP). The works are also categorised ...

  • A method for identification of irregular objects under noisy conditions

    In the present paper, we propose a method of detecting amorphously shaped objects in real-time ultrasonic images when high level of noise is present. In general, noisy imaging environment can lead to faulty object segmentation. Shape recognition algorithms can give ambiguous results even for detecting objects with permanent shapes. From prior knowledge, indexed object templates are introduced ...
