  • Ventilation Research on Australian Residential Construction

    This paper applies established and new testing methods to discover the ventilation performance of various residential building envelope constructions in Australia. Under the definition of 'ventilation performance' we imply the building envelope leakage (or infiltration) of the living space air change rates, the volumetric flow rates and the pathways of air flow between subfloor, living and roof ...

  • New Animal Transfer Station Offers Improved Containment and Allergen Control

    When using animals in research, protecting the animal from both the lab environment and cage-to-cage cross-contamination are a researcher’s highest priorities. Today, increased awareness of the potential health hazards presented to laboratory workers by animal allergens has led to an increase in the importance of personnel protection as well. Typically when personnel, product, and ...

  • Keeping Pace with PTP and CCRL

    Two, three or four times a year, laboratories around the world check their performance with testing programs from ASTM International’s Proficiency Testing Program and the Cement and Concrete Reference Laboratory. Using samples sent for a particular program cycle, labs run specific methods and submit their results to PTP and CCRL for analysis. Each lab then receives reports that serve as a ...

  • PETROTOX: An aquatic toxicity model for petroleum substances

    A spreadsheet model (PETROTOX) is described that predicts the aquatic toxicity of complex petroleum substances from petroleum substance composition. Substance composition is characterized by specifying mass fractions in constituent hydrocarbon blocks (HBs), based on available analytical information. The HBs are defined by their mass fractions within a defined carbon number range or boiling ...
