  • Fire Codes: A Foundation of Safety for a Rapidly Changing World

    Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that have been adopted in whole or in part ...

  • Tidal influences on unconfined water levels in wells.

    Tidal effects have the potential to measurably affect water level measurements and the estimation of groundwater flow direction and gradient. This has significant implications for the prediction and monitoring of contaminant plumes in coastal areas. Studies were conducted at two near-coastal sites in San Diego County, California, to evaluate the impact of tidal variability on the interpretation ...

    Pulsar's superior echo processing was proven once again in this difficult very deep Welsh wet well application featuring a 23m 'shot' that needed to follow the level between the heads of two submersible pumps. The reliability and versatility of the advanced echo processing technology in Pulsars non-contact ultrasonic range has been utilised at the SwanseaWasteWater TreatmentWorks, in a 23m deep ...

  • Waste management and well-being

    There was the Industrial Revolution in Europe, followed by the Automobile Revolution in the early-to-mid 20th century. The Green and White ones followed after that in the Asian countries. The IT and telecom revolution has transformed lifestyles in the last two decades. After having nourished ourselves with the bounties of Mother Earth, it is time to give back, be grateful and conserve the ‘Gaia’ ...


  • Regional modeling of wells

    The ability to represent wells in a regional three-dimensional numerical groundwater model is crucial for many modeling exercises. Such wells can either be measurement wells where groundwater levels are measured as a function of time, or wells can be pumping wells in which water is removed from the well and a drawdown cone is created in the water table surrounding the well. There are numerical ...

  • Latin America well-positioned for CDM

    The coastal desert of Colombia’s La Guajira state is a world away from Kyoto, the temperate Japanese city where representatives of 159 countries in 1997 signed the Kyoto Protocol on reducing greenhouses gases. The Caribbean laps against rickety settlements. Herds of goats range across scorching sands. Months, whole years, pass without rain. But Kyoto is well known to the inhabitants of La ...


  • Scrubers with a level head

    The available methods for removing pollutants from a gas stream are numerous, to say the least. A popular method, scrubbers allow users to separate gases and solids by allowing the gas to come into contact with a liquid stream. In the end, the pollutants are washed away in the effluent, and the gas exits the system to be used in later processes or to be released into the atmosphere. For many ...
