  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Improved Aseptic Processes and Monitoring to Reduce FDA 483s

    Abstract In recent years, the FDA response to companies with insufficient proof of control over their production has become more aggressive, demonstrated by the rise in 483s and warning letters issued. Topics related to environmental monitoring programs are included in the most common reasons 483s are issued. By becoming aware of the regulations and reasoning backing 483 distribution, ...

  • A Dynamical Perspective on Atmospheric Temperature Variability and its Response to Climate Change

    The atmospheric temperature distribution is typically described by its mean and variance, while higher order moments, such as skewness, have received less attention. Skewness is a measure of the asymmetry between the positive and negative tails of the distribution, which has implications for extremes. It was recently shown that near-surface temperature in the southern hemisphere is positively ...

  • A mathematical approach for the analysis of data obtained from the monitoring of biocides leached from treated materials exposed to outdoor conditions

    Leaching processes are responsible for the release of biocides from treated materials into the environment. Adequate modeling of emission processes is required in order to predict emission values in the framework of the risk assessment of biocidal products intended for long-term service life. Regression approaches have been applied to data obtained from the long-term monitoring of biocide ...
