  • Wind turbines cause rising number of bird and bat fatalities

    Wind power is one of the cleanest and safest methods of generating renewable energy. Due to the steady increase in price of nonrenewable sources, wind turbine use has increased 25% in the past decade.i While its growth has helped reduce carbon emissions and pollution, this green source of energy comes at a cost: these massive blades, slicing the air at close to 200 miles per hour, serve as ...

  • Breaking into new industries—The Bird-X approach

    In golf, a ‘birdie’ is usually a good thing. After attending February’s Golf Industry Show in San Diego, Bird-X found out that birdies are causing quite the stir on golf courses across the country. The reason is the number one pest bird culprit on golf courses—the Canada goose. Canada geese congregate around ponds and lakes, and have ...

  • Fitting germplasm types of tall fescue and orchardgrass to different cropping environments of the mediterranean region

    Understanding of adaptation targets, selection environments, genetic resources, and plant types is required in breeding tall fescue [Lolium arundinaceum (Schreb.) S.J. Darbysh.] and orchardgrass (Dactylis glomerata L.) for Mediterranean environments prone to drought stress. Fourth-year forage yield of seven orchardgrass and five fescue cultivars grown in Algeria and Sardinia revealed (i) ...

  • Railroads in the Amazon: A key strategy for reducing deforestation

    The article examines the impacts of paving highway BR-319, which connects two of the largest state capitals in the Brazilian Amazon. In recent years, the construction of highways has been the biggest driver of deforestation in the region. As currently planned, BR- 319 will run through the middle of the largest contiguous area of intact forest in Brazil. By 2050, the deforestation projected to ...

  • Rural community sewerage case study

    Succeeded in "zero-emission" of sludge Previously, sludge was vacuumed out in this treatment plant without being dewatered; however, the cost for sludge treatment was huge. Thus, aiming at "zero-emission" of sludge, fermentation of the sludge was being considered. AMCON's offer for a solution They introduced Dell Compo, which can treat sludge ...

  • Summer dormancy in orchardgrass: evaluation and characterization through ecophysiological and genetic studies

    Climatic change manifested by increasing summer drought necessitates the development of drought-tolerant forage grass cultivars. Summer dormancy is a major trait conferring drought survival and autumn recovery of perennial grasses in Mediterranean areas. Moroccan ecotypes of orchardgrass (Dactylis glomerata L.) expressed 67% greater degree of summer dormancy than tested cultivars except the ...

  • A dynamic model of cotton emergence based on the thermal dependence of malate synthase

    Cotton (Gossypium hirsutum L.) is frequently planted when temperatures are not optimal for germination and emergence. Delayed emergence, a common contributor to diminished plant performance later in the season, is often related to nonoptimal temperatures. Improvement of cotton performance requires knowledge of the source, pattern, and magnitude of thermal limitations on seedling metabolism. In ...

  • Efficacy of selected probiotic cultures to inhibit Enterobacter sakazakii ATCC 12868 in model reconstituted dairy products

    Enterobacter sakazakii ATCC 12868 ( ES ) is a very dangerous opportunistic organism likely to contaminate post-pasteurised dry milk products with a high mortality rate (40–80%). This study evaluated the antimicrobial efficacy of probiotics against ES in reconstituted dried infant formula. Initial study at 30ºC showed that Enterococcus ...

  • Optimum short-term futures hedge using stochastic linear programming

    Classical optimal hedge ratio concentrates on risk reduction and neglects strategic value maximisation. In this study, the authors use stochastic optimisation theories to formulate an optimal, short-term hedging scheme to mitigate risks while maximising portfolio value. Stochastic spot and futures price models are used to simulate prices. The periodic optimal hedge ratios are determined using the ...

  • Timber frame and post and beam construction

    Timber framing and "post-and-beam" construction are a unit strategies of building with heavy weight timbers instead of dimensional timber like 2"x4"s. Timber framing is sometimes additionally known as post and beams because as it is evident for its name that it is a way of using frame made of timber wood for construction because it acts as the main structure providing support to the ...


  • Common Fish Diseases and Caused Reasons

    There are literally hundreds of afflictions that can effect the health of farm fish. The most common maladies seen in home aquaculture production are usually either bacterial, parasitic, or viral diseases in origin. Fungal infections are also sometimes seen, and occasionally physical ailments. Common ...

  • Adsorption kinetics, isotherms and thermodynamics of atrazine removal using a banana peel based sorbent

    Atrazine removal from water by treated banana peels was studied. The effect of pH, contact time, initial atrazine concentration, and temperature were investigated. Batch experiments demonstrated that 15 g L−1 adsorbent dosage removed 90–99% of atrazine from 1–150 ppm aqueous solutions. The removal was both pH and temperature dependent with the most atrazine removed between pH 7 and 8.2 and ...

  • Autoregressive conditional moments in VaR estimate with Gram-Charlier and Cornish-Fisher expansions

    This paper proposes a model to compute value at risk by means of Gram-Charlier and Cornish-Fisher expansions. In this model VaR is a function of conditional mean, volatility, skewness and kurtosis where all the moments are computed via a time-varying dynamic. An appropriate form of Gram-Charlier density is used to estimate the parameters of the equations proposed for the first four autoregressive ...

  • Optimal Bayesian portfolios of hedge funds

    Hedge fund returns are not normally distributed. Hedge fund styles related to arbitrage strategies exhibit negative skew while more directional styles, such as managed futures and global macro, are more positively skewed. We implement and test a Bayesian framework for portfolio optimisation process in order to take these characteristics, as well as the estimation risk, into account. Hedge fund ...

  • Changing intellectual property regimes: implications for developing country agriculture

    The revolutions in biotechnology and intellectual property protection began in the developed world. The USA led the global transformation of intellectual property protection, and has been the leader in commercialisation of biotechnology in agriculture. Now all members of the World Trade Organization are committed to offer intellectual property protections for agriculture. Will the benefits of ...

  • Microbial community composition and reactor performance during hydrogen production in a UASB reactor fed with raw cheese whey inoculated with compost

    This study investigated the microbial community developed in a UASB reactor for hydrogen production and correlated it to reactor performance. The reactor was inoculated with kitchen waste compost and fed with raw cheese whey at two organic loading rates, 20 gCOD/Ld and 30 gCOD/Ld. Hydrogen production was very variable, using an OLR of 30 gCOD/Ld averaged 1.0 LH2/Ld with no methane produced under ...

  • Agriculture, business and development

    This paper argues that building effective partnerships between multinational corporations and local Small and Medium-sized Enterprises (SMEs) is essential for stimulating growth in African agricultural economies. Policies that provide incentives for multinational corporations to build domestic capacity are critical to growth. Africa therefore needs to create enabling environments for business ...

  • Innovation, agricultural growth and poverty reduction

    There is increasing agreement that agricultural growth matters for poverty reduction and has a significance extending well beyond the agriculture sector. Examples of successful research and innovation support by DFID show the central role of science and research in technological innovation. Technology cannot be viewed in isolation from innovation in policies and institutions. These provide ...

  • Denver international airport case study

    Denver International Airport (DIA) serves 22 commercial airlines, offering non-stop service to more than 150 destinations worldwide. In 2008, DIA handled over 51,000,000 passengers. With an airport elevation of 5,431 feet and 53 square miles of property, Denver International Airport has a historical reputation for massive snow-fall — at times, even overnight. DIA’s snow removal is ...
