  • Working remotely and the LIMS solution

    Now that cell phone and internet coverage are virtually everywhere, it is extremely difficult to disconnect from work. Believe me, I know; I’ve been hiking up the side of a mountain in NC and still received phone calls and emails. Answering work related phone calls while out of breath and telling your five year old to be quiet at the same time can be quite a challenge. However, that kind of ...

  • The fundamental conductivity and resistivity of water

    Pure water has a very low. but not quite zero, electrical conductivity. This conductivity provides a probe into fundamental properties of water, including the electrochemical mobility of the hydrogen and hydroxide ions. Deviation from this value is a measure of trace ionic impurities. Ultrapure water (UPW). with impurities at or below the sub-parts-per-billion range, is used extensively in many ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • MASW and resistivity sounding case study

    Anclote Natural Gas Conversion Project, Pasco County, FL  Our client was coordinating the conversion of an oil-burning power plant to natural gas. As part of the associated geotechnical study, GeoView, Inc. was tasked with determining the S-wave velocity and vertical resistivity structure at the site. For the seismic portion of the study, MASW (Multi-channel Analysis of Surface ...

  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...

  • A new categorisation method of resistivity instruments

    This paper presents a new categorisation method of resistivity instrument: Conventional arrays-oriented resistivity instruments (conventional instruments) vs. Comprehensive array-oriented resistivity instruments (comprehensive instruments). The conventional instruments were ...

  • Superior abrasion resistance demanded by sump cleaning

    Acquired by a open pit mining company located in the Minas Gerais province for a slurry application (up to 60% solids concentration) in a sedimentation sump, the Grindex Bravo 60 pump lived up to its name, proving it's the ideal solution for a wide range of similar installations. In this case ...

  • Sorption and resistant desorption of Atrazine in typical Chinese soils

    Atrazine is one of the most commonly used herbicides and is produced and used in large quantity worldwide. In the present study, the sorption and desorption of atrazine in five typical Chinese soils were examined. The sorption of atrazine followed the conventional linear isotherm reasonably well, indicating that sorption was driven largely by hydrophobic partitioning into soil organic matter. ...

  • Exploring Soil Resistivity in Lima, Peru - Case Study

    In April 2013, in partnership with SensorVital and Pontificia Universidad Católica del Perú, AGI conducted a workshop focused on exploring the resistivity of shallow soil at Pontificia Universidad ...

  • New and diverse sources of multiple disease resistance in Wheat

    Tan spot (caused by Pyrenophora tritici-repentis) and Stagonospora nodorum blotch (SNB), (caused by Phaeosphaeria nodorum) are destructive diseases of wheat (Triticum aestivum L.). The majority of currently grown wheat varieties are susceptible to both diseases, presumably because of high pathogenic variability occurring in these fungi or narrow genetic background for resistance in wheat ...

  • Using Resistivity for Basalt Site Characterization - Case Study

    Purpose A mining company in Turkey hoped to determine existing and new alternative basalt zones at an existing basalt mining site by using Electrical Resistivity Imaging (ERI). Process Our client, Ali Karan, used 84 electrodes spaced at 10 meters and two lines 5 meters apart inside the study ...

  • Time-lapse resistivity investigations for imaging saltwater transport in glaciofluvial deposits

    Abstract  Five intersecting resistivity sections have been measured in glaciofluvial deposits hosting an aquifer of regional importance situated along a heavy traffic highway in Sweden. The winter salt spreading has caused a regular salinity increase through the years. For imaging the transport of saltwater in the aquifer, the sections were measured exactly in the same location before and ...


  • Pullout Resistance of Steel Geogrids with Weathered Clay as Backfill Material

    The pullout resistance of welded steel geogrid reinforcement embedded in poor-quality, cohesive-frictional backfill material such as weathered clay was investigated. Laboratory pullout tests were conducted on various reinforcement sizes, mesh geometry, and compaction conditions of the backfill material. Field pullout tests were also conducted to investigate the pullout resistance of ...
