  • Three Reasons Why It’s Time to Invest in Your Own Air Purity Test Kit

    The costs of hiring someone to test your breathing air lines on site can quickly add up, have you ever considered doing your own tests? The use of breathing masks and compressed breathing air is a vital component of maintaining safety standards on site. The air produced protects workers in spray booths, car body shops and other applications where isocyanate paint mixtures are ...

  • Single family home case study

    After treating with EBB for visible mold on a leaky roof, an environmental company was brought in to test the air quality... The air inside the building is supposed to have the same concentrations of spores etc. as the outdoor air. The testing came back to show spore concentrations of up to... 10x lower than that of the outdoor air. I was excited about the results... My client was ...

  • Gas Chromatography: MCERTS Certification for Ambient Air Analysis on Benzene and VOCs

    Due to environmental issues, the world of gas analysis is evolving very rapidly. Governments set the rules to limit and control the environmental pollution through legislation. Volatile organic compounds (VOCs), often produced by human activities, are amongst the sources of pollution that need to be identified and quantified for safety reasons. Exposure to high concentrations of certain VOCs is ...

  • An efficiency study of airlines and air cargo/passenger divisions: a DEA approach

    In this paper we investigate the question of whether a high degree of cargo business improves the operational efficiency of a mixed passenger/cargo airline. We use Data Envelopment Analysis (DEA) to compute the efficiency scores for major airlines in the world and then carry out non-parametric statistical tests. Using data for 29 airlines during the period 1998-2002, we find that airlines with a ...

  • Measuring intermodalism at European port cities: an employment-based study

    Since many studies on intermodalism face a lack of empirical evidence and comparative research, this paper focuses on the modal distribution of employment among 76 European port cities. Data is collected from 9,000 companies and more than one million employees involved in port, sea, air, road, rail, warehousing, forwarding, and logistics, together with population, port, and air traffics. Results ...

  • Measuring Anisotropic Elastic Properties of Sand Using a Large Triaxial Specimen

    An advanced automated triaxial testing system developed to characterize elastic behavior of soils is described. Small axial and lateral strains of a large rectangular prismatic specimen were measured locally at various stress states along a specified stress path, which was achieved by automatically controlling axial load and confining pressure. Elastic deformation was measured by applying very ...
