  • Influence of the Stirring Mechanism on the Precision of the Fusion for VITRIOX GAS and ELECTRIC

    Introduction Homogenization of the melt is an important aspect of sample preparation for X-ray fluorescence analysis using fusion. Whether the fused bead breaks or remains mechanically stable after cooling, depends largely on the homogenization. Once a stable fused bead has been obtained, it is only possible to judge if the sample is truly homogeneously dissolved in the flux by way of ...

  • Return on Investment Using MANTECH Multi-Parameter Analysis Systems - Case Study

    Since 2008 Eurofins has been using MANTECH systems at various facilities around the world. Their first system ran 200,000 samples in five years. The unit analyzed 7 different parameters per sample and operated 24 hours/day, 7 days/week. This generated €5,000,000 in revenue. Their initial investment was €60,000. The system discussed in this case study analyses pH, conductivity, ...

  • Water Treatment System Types and Their Benefits

    Water is one of the most important utilities in the world. It’s used for bathing, cooking, washing clothes, cleaning dishes, and drinking. If you get your water from the city, you trust your tap water to be clean and healthy. It goes through a treatment plant before it reaches you, so it’s perfectly purified when it reaches you—right? Unfortunately, this isn’t always the ...

  • H-ADCP Flow Gauge Installation

    Wessex Water contracted HL to install a new flow-gauge to provide flow data on the environmental impact of abstraction upstream and downstream of a riverside borehole for public-supply. Due to the channel and hydraulic conditions at the site on the River Yeo in Somerset, HL selected a horizontal ADCP Channelmaster device from Teledyne RDi for providing accurate velocity profiles at one elevation ...

  • A moldy summer and the 3 H’S hot-humid-hurricanes

    A HOT WET SUMMER Once again, we’ve entered the hurricane season, when hot humid air envelops most of North America. Beginning in the Spring and lasting until the first frost of Autumn, the air is typically well above 60% Relative Humidity, which is ideal for promoting the growth of mold. The official Hurricane season runs from June to September, and even though they may not qualify as ...

  • Larry H. Miller dealership remodel case study

    In October 2012, the Larry H. Miller Group (LHMG) determined that renovating three of its Peoria, Arizona, dealerships was necessary to remain competitive in the Phoenix market. They embarked on an eight-month-long project that included a complete re-facing of two buildings and a demolishing and rebuilding of the third. The goal of the project was to update showrooms and increase brand ...

  • Ultrasonic degradation of 1-H-benzotriazole in water

    This paper reports on the effect of different parameters of ultrasonic power, pollutant initial concentration, pH and the presence of co-existing chemical species (oxygen, nitrogen, ozone, and radical scavengers) on the ultrasonic degradation of the endocrine disruptor 1-H-benzotriazole. Increasing the 1-H-benzotriazole initial concentration from 41.97 to 167.88 μM increased the pollutant ...

  • Erratum: Water Science and Technology 72 (7): Development of a new wastewater treatment process for resource recovery of carotenoids, H. Sato, H. Nagare, T. N. C. Huynh and H. Komatsu, doi: 10.2166/wst.2015.330

    A new wastewater treatment process that involves coagulation, ozonation, and microalgae cultivation has been developed. Here, two challenges are discussed. The first was minimizing phosphorus removal during coagulation in order to maximize algal production. The second was to optimize microalgae cultivation; algal species that grow rapidly and produce valuable products are ideal for selection. ...

  • An integrated H-infinity optimised fuzzy controller for UPFC in multimachine power systems

    A detailed mathematical model of a multimachine power system with unified power flow controller (UPFC) has been developed with a view to control the active and reactive power flow in the transmission line and to improve transient stability performance. Thus, initial voltage and angles of the series and shunt voltage sources are computed and used during transient stability studies. After the power ...

  • Efficient pre-processing watermark for robust video watermarking of H.264/AVC

    This paper proposes a greyscale pre-processing and robust video watermarking algorithm for the copyright protection application in the emerging video coding standard H.264/AVC. The watermark is first transformed by a Hadamard transform and modified to accommodate the H.264/AVC computational constraints before it is inserted into video data in the compressed domain. This approach leads to good ...
