  • A novel community-based water recreation area for schistosomiasis control in rural Ghana

    Primary prevention of schistosome infection has received little attention of late. We describe a novel water recreation area (WRA) to reduce Schistosoma haematobium infection rates in Adasawase, Ghana. Urogenital schistosomiasis is a water-based parasitic disease that affects over 100 million people worldwide, primarily children in the rural tropics. The disease is contracted via dermal contact ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Wind modelling based on wind input data conditions using Weibull distribution

    Weibull distribution can be used to model the wind speed distribution at a particular site and hence, it can help in wind resource assessment (WRA) of a site. By calculating the shape (k) and scale (c) parameters for Weibull distribution, the wind speed frequency curve for a site can be made. Once this wind speed distribution for site is determined, it can be convolved with the power curve for a ...

  • Storing Heat Underground

    Underground thermal energy storage (UTES) is a system that uses inter-seasonal heat storage, storing excess heat from the summer for use in winter heating, and the cooling potential from winter for cooling in summer. A cost-effective, low-energy and low-risk proven renewable technology, UTES reduces carbon emissions by up to 60% and is becoming an increasingly popular choice for residential, ...

  • Top 10 questions you should ask when purchasing a control valve

    Automatic control valves, much like everything else we purchase these days, are not all created equal. Some fall into the high quality bracket with pricing to match, while others hover closer to the lower quality and price sensitive end of the scale. Unfortunately, when evaluating control valve prices, it is not always clear what you are being offered ...

  • Universal Input LED Lamps – How do they work?

    In commercial lighting applications with HiD or older 2 pin fluorescent lamps, a magnetic ballast is used to control the energy in the arc lamp. In the first generation of LED replacement lamps, two kinds were available: LED lamps that only worked with the ballast – such as Lunera’s Gen1 & Gen2 Susan families – known by DLC as a “type-A” lamp; LED Lamps ...

  • Hydraulic modeling - Bethel Park Municipal Authority - Case Study

    Treatment plant hydraulics is often overlooked as one of the most important aspects of treatment plant design, especially in plant upgrade scenarios where retrofitting new equipment or processes into the existing treatment train will create additional hydraulic restrictions.  Many existing plants already have a minimal amount of head available for passing peak flows through the system, which ...

  • World’s 37 Most Water-Stressed Countries

    Providing stable freshwater supplies is a priority for every country in the world. Yet stable supplies are increasingly hard to come by in many countries, as water-related risks increase. For example, recent droughts threatened GDP growth in the United States. ...

  • Understanding Climate Change

    Understanding the intricate dynamics of climate change is not easy. Even reducing climate change to one simple metric such as average mean temperature, or number of extreme weather occurrences, leaves unanswered a host of nagging questions and a complex of array of real world facts inconsistent with whatever yardstick one choses. One example cited in an insightful essay on climate change ...
