  • Case study - Use of the Nor848A acoustic camera on wind turbines

    The acoustic camera system Nor848 is a powerful tool to investigate noise sources. In realtime you listen to a beamformed audio signal so that you can hear individual sources one by one. Immediately you can identify the strongest over all noise source in a multisource environment, and you can do the same analysis for single frequencies, 1/3 or 1/1 octave bands or any given frequency range. This ...

  • Following the fuel: How portable biomass energy generation may help rural communities

    The forests that surround many of California’s mountain communities tend to have an abundance of woody biomass and a pressing need for thinning to reduce fire danger. Revenue from selling forest residues to biomass power plants could help to support fuel reduction activities, but in many cases the nearest plant is so far away that hauling costs are prohibitive. The remoteness of such ...

  • Odour Control at Pesticide Facilities: Eliminating volatile compounds

    Chemical formulation plants are susceptible to emissions of unpleasant and malodorous volatile compounds, a fact which makes the implementation of efficient odour control measures essential. North-western Spain is home to one of the country's oldest industrial sites for the manufacture of phytosanitary products, with some facilities located relatively close to populated areas. Recently, the ...

  • Technical and safety practices

    Safety is absolutely paramount in the medical industry, with lives literally at stake if something were o go wrong. Regrettably, this was more than reinforced recently following the tragic news of a death of a newborn at a hospital in Sydney, Australia, after it was mistakenly administered nitrous oxide (N2O) instead of oxygen (O2) in July this ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Transformation of the waste business influences all business owners

    Even if recycling was expensive and unprofitable in the past, it will not be that in the future. We need to stop landfilling valuable materials for the sake of our business and for the sake of the globe. A huge, global transformation in waste management has already begun. The biggest driver of change is related legislation that makes us shift towards recycling and material recovery. The pace ...

  • Mechanisms of scale deposition and scale removal in porous media

    Calcium sulfate scaling and scale removal have been studied experimentally and theoretically in a well-defined unconsolidated porous medium. The effects of injection rate, scale concentration and temperature on the rate of scale formation and the rate of its removal are investigated. The results of the experiments are used to develop mechanistic models for the prediction of the scaling process in ...

  • Large Scale Groundwater Modelling

    The hydrological model LISFLOOD is a spatially-distributed, partially physically-based rainfall-runoff model that has been devised to simulate the hydrological behaviour in large European catchments, with emphasis on predicting floods and droughts. In the model the groundwater component is represented by two interconnected linear reservoirs, with the outflow in some unit of time being ...


  • ADMS–Urban: developments in modelling dispersion from the city scale to the local scale

    Many countries perform national air quality assessments using grid–based numerical air dispersion models, generally referred to as 'regional' models. Advantages of these models include the ability to use temporally and spatially varying meteorology and model chemical reactions over large temporal and spatial scales. These models usually perform reasonably well against rural and urban background ...

  • Research on the synthesis and scale inhibition performance of a new terpolymer scale inhibitor

    A new terpolymer named β-CD-MA-SSS was produced using free-radical polymerization of β-cyclodextrin (β-CD), maleic-anhydride (MA) and sodium-styrene-sulfonate (SSS) as monomers, with potassium persulfate (KPS) as initiator. Its performance as a scale inhibitor to prevent deposition of calcium carbonate (CaCO3) has been investigated. Experimental results demonstrated that β-CD-MA-SSS performed ...
