  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • Transformational adaptation – when climate change means business as usual is no longer possible

    1. A lesson from the past Deep in the central Sahara, a crumbling mud-brick town sits at the edge of a dry lake bed. This is the medieval town of Germa, in southwestern Libya, one of a string of settlements along the Wadi al-Ajal, a valley defined by the towering dunes of the Ubari Sand Sea to the north, and the black cliffs of the Messak Settafet plateau to the south. Germa is romantic ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • From gasworks to playing field case study

    There had formerly been a gasometer on this site, which had contaminated 3000 cubes of soil with an average TPH of 6,500mg/kg and an average PAH of 400mg/kg. Sanctus, the contractor for the work, were looking for a way of treating the soil on site and avoiding any landfill costs. We suggested to them that they apply two litres of Alga Power 101, our unique seaweed-based media, with 100g of ...

  • Super BirdXPeller PRO: wrigley field case study

    Wrigley Field strikes out the birds with Bird-X Wrigley Field, home of the Chicago Cubs, celebrated its 90th season in 2003. As Wrigley Field prepared to play host to all of the Cubs’ NL rivals, the stadium also battled an unwelcome new preseason one: pigeons found a home in the upper deck. It isn’t only Cubs fans who love Wrigley Field. “Pigeons like to roost on ...

  • Study of the use of thermoluminescent materials in mixed fields

    The scientific research and the application of the thermoluminescence phenomenon have been advancing for the last two decades. Thermoluminescent Detectors (TLDs) present advantages when used in dosimetry. These advantages include reduced size and the non-use of wires. As a disadvantage, we see the loss of all signals after the reading (information) of the detectors. In the present study, we used ...

  • Use of terrestrial field studies in the derivation of bioaccumulation potential of chemicals

    Field‐based studies are an essential component of research addressing the behavior of organic chemicals, and a unique line of evidence that can be used to assess bioaccumulation potential in chemical registration programs and aid in development of associated laboratory and modeling efforts. To aid scientific and regulatory discourse on the application of terrestrial field data in this manner, ...

  • Influence of different organic amendments on the leaching and dissipation of Terbuthylazine in a column and a field study

    Received for publication April 9, 2008. Terbuthylazine (TA) is a herbicide that has been introduced for weed control in corn cultivations as a direct replacement for atrazine. Because incorporation of different organic amendments (OAs) is a common practice in this crop, this study investigated the effects of different OAs, including urban sewage sludge, poultry compost, and corn straw on the ...

  • Granular ferric hydroxide adsorbent for phosphate removal: demonstration preparation and field study

    Ferric hydroxide (FHO), which has high phosphate adsorption capacity, was prepared by precipitation at industrial scale and then fabricated via the drum granulation method with cross-linked poly(vinyl alcohol) as the binder. The optimum binder/FHO powder ratio was 0.6 for producing a granular adsorbent with a high phosphate adsorption capacity and stability. The Langmuir maximum adsorption ...

  • Energy performance indicators of wastewater treatment: a field study with 17 Portuguese plants

    The energy costs usually represent the second largest part of the running costs of a wastewater treatment plant (WWTP). It is therefore crucial to increase the energy efficiency of these infrastructures and to implement energy management systems, where quantitative performance metrics, such as performance indicators (PIs), play a key role. This paper presents energy PIs which cover the unit ...

  • Point-of-use chlorination of turbid water: results from a field study in Tanzania

    Household-based chlorine disinfection is widely effective against waterborne bacteria and viruses, and may be among the most inexpensive and accessible options for household water treatment. The microbiological effectiveness of chlorine is limited, however, by turbidity. In Tanzania, there are no guidelines on water chlorination at household level, and limited data on whether dosing guidelines ...
