  • An Overview Of STI Group’s Core Industrial Services

    It takes numerous specialists and engineers to manage industrial plants and facilities and keep them running smoothly, efficiently, and safely. Some of these individuals may only be required during special projects or industrial turnarounds when speed and efficiency are of the essence to get the plants back into production as quickly as possible. Other times industrial services are required on a ...

  • Installing Continuous Multi-Chamber Tubing Using Sonic Drilling

    As a geologist, core is the first thing that comes to mind when talking about sonic drilling— continuous, near complete core recovery through almost any lithology. Sand to silt transitions can be logged on a centimeter scale if desired. Geologic contacts can be mapped with accuracy of less than one foot. In an environmental ground water assessment, it seems an awful shame to collect (and pay for) ...

  • Coiled Tube Turbodrilling: a proposed technology to optimise drilling deep hard rocks for mineral exploration

    The need to drill deep boreholes more efficiently for mineral exploration has raised the attention to investigate the feasibility of recent drilling technologies for such applications. The two principal methods of Reverse Circulation (RC) and diamond core drilling are usually used in combination by mine operators are subjected to certain limitations and inefficiencies. Considering that delivering ...

  • The Effects of Centerline Tube Sampling Strains on the Undrained Behavior of Two Stiff Overconsolidated Clays

    Some of the effects of tube sampling of stiff clays are examined. A strain path that simulates strains at the centerline of a tube sample as it is captured by a penetrating sampling tube was applied in the triaxial apparatus. Undrained triaxial strain path tests were performed on two stiff overconsolidated clays that had not previously been subjected to tube sampling. The response of the clays ...

  • Small-increment electric soil sampler

    Measurement of soil bulk density and volumetric water content in small (2-cm) depth increments is tedious and time consuming. Most methods require compositing several subsamples to control measurement error, and few are feasible with loose, dry soils. We developed and tested a sampler that uses an electric linear actuator to push an intact soil core out of the sampling tube. The soil core is ...

  • Computational study on performance of circular concrete filled steel tubular columns

    The structural behaviour of circular concrete filled steel tubular (CFST) columns with different geometries and filled with different grades of concrete, have been investigated analytically using the numerical results of three dimensional non-linear finite element model, which has been developed using commercial finite element code ANSYS. The steel tubes were having different lengths, diameters, ...

  • Rehabilitating and protecting coastline of Grand Isle - case study

    Worldwide TenCate Geotube technology is used in environmental and infrastructural projects. Currently, TenCate Geosynthetics North America is working with the US Corps of Engineers on rehabilitating and protecting the coastline of Grand Isle (Louisiana, USA). A row of TenCate Geotube GT500 containers measuring 9,600 metres in length forms the core of what will ultimately be a row of dunes. The ...

  • Geo Drilling International: Hands-On

    Boart Longyear has launched a core-orientation system made for drillers, by drillers Although critical for mapping exploration and minesite development, core orientation is part of the drilling process that has experienced only incremental product improvements through small changes to the process and equipment. Boart Longyear has now introduced TruCore, a first-inindustry integrated ...

  • Assessing Frost Damage in Compacted Clay Liners

    Methods used to assess frost damage (here defined as a large increase in hydraulic conductivity) in compacted clay liners are reviewed and evaluated using data collected from two test pads that were instrumented and then exposed to winter weather. The methods include comparisons of measurements of either water content and dry unit weight or hydraulic conductivity made before and after winter ...

  • Fabrication of carbon-nanotube enhanced piezoelectric membrane for biosensor application

    This paper reports on a carbon-nanotube (CNT) enhanced piezoelectric membrane for the possible application as a mass sensitive biosensor. CNT possesses a hollow core and large specific surface area that could be used for bio-molecular binding. A larger number of probe molecules on the surfaces of CNT could capture more target molecules and therefore increase the detection sensitivity of the ...

  • International joint venture of two giants in the CRT industry: strategy analysis using system dynamics

    The past decade has seen a dramatic rise in the number international joint ventures (IJV) and a great majority of them fail. Although the research literature continues to expand, there is an imbalance to the attention paid to the process and operational management side of IJVs. We begin this article with a survey of the literature and we segment the research stream into the life cycle phases of ...

  • Metal finishing - Columbia manufacturing company - case study

    Application Columbia Manufacturing Company of Westfield, Massachusetts began producing bicycles in 1877. The company, while still producing bicycles, transitioned its core product line to institutional furniture with chrome plated bases made from tubular steel. Large amounts of potable water were required for the old plating system. The company was using 180,000 gallons of potable water a ...


  • Brief Introduction of Different Cables

    There are generally two kinds of cables: armored cable and non-metallic cable, that is, AC cable and NM cable. What are they and their difference? Armored cable is a type of power-conducting cable that is covered in a metal sheath. In most cases, it consists of a bundle of wires covered in a metal tube, which may be covered in a plastic insulation layer. The various types of metal-covered cable ...

  • Case study: Formaldehyde production

    Overiew A major chemical manufacturer required a pollution control system with minimal operational cost to destroy the Hazardous Air Pollutant (HAP) by-products of a formaldehyde production process. A key issue was system reliability; the plant operates 24 hours a day and only shuts down once per year for plant-wide preventive maintenance. ...

  • Cryotherapy is Cool

    Cryotherapy is a real facet of medical treatment that uses extremely low temperatures to help with pain and inflammation.  Not to be confused with cryopreservation, in cryotherapy the patients are only subjected to the cold for minutes. It seems like something futuristic, but it is actually an increasingly common treatment among athletes to replace ice baths and ice pack ...

  • FTIR gas analyzers support management of fire at UK waste facility

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents.  Arrangements have been made in England to bring together experts from the Environment ...
