  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Nitrogen fixation of Sulla under Mediterranean conditions

    Sulla coronaria (L.) B.H. Choi & H. Ohashi (=Hedysarum coronarium L.) is a Mediterranean forage legume grown extensively in rainfed Italian environments. Here we report the field quantification of its seasonal and annual N fixation, using the 15N isotopic dilution (ID) method, the influence of various nonfixing reference species on these estimates, and the allocation of fixed N between the ...

  • 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 ...

  • Sedimentation of chlorophylls in an Arctic fjord under freshwater discharge

    Sedimentation of chlorophylls was studied during summer 1997 in Adventfjorden (Spitsbergen, Arctic). During the period of study, the water column was found to be well stratified by a freshened surface layer (salinity ...

  • 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 ...

  • Bank shares restore under recent industry bailouts

    This paper structures ten effective implications/lessons of the most recent bank bailouts of 2007-2009 in the Western economy model when analysing actual shareholders' value retrenchment or growth opportunities. The author finds that recent bank bailouts relate to: global bailout interconnections, economic downturn and liquidity boost, abnormal returns, efficiency recovery, evade social costs, ...

  • Cohesive Soil Behavior Under Random Excitation Conditions

    A testing program was undertaken in which cohesive soil at different confining pressures was tested in a resonant column device using random torsional excitation in addition to conventional sinusoidal excitation. The damping and shear modulus from random loading testing were determined by both the power spectral density function and the transfer function method. Evaluation of the dynamic soil ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Lessons learned from potato growers down-under

    Andy Alexander, specialist potato consultant and agronomist, has provided advice across the UK and Australia for over 35 years, and has travelled to the southern continent over 17 times. He explains how adapting to change in a volatile climate has been key to success for growers in Australia, and what lessons UK growers can take from this. “My role is to provide business ...

  • Durability performance of RUHTCC beam under flexural load

    Aiming at design issues of strictly anti-cracking structures or aseismic design in crucial locations of structures when using ultra high toughness cementitious composite (UHTCC), investigations on flexural behaviour of reinforced UHTCC (RUHTCC) members are carried out by virtue of excellent crack dispersion and strain energy absorption abilities of UHTCC. According to elastic theory, theoretical ...
