  • Researchers are Advancing Science Using Micro Pulse LiDAR Technology

    There are so many examples of interesting research using Micro Pulse LiDAR (MPL) technology it is difficult to decide on my favorites; however, I have chosen to highlight the following two papers because these applications for the MPL and MiniMPL address problems that are very important to global health. ...

  • Supercooled Liquid Water is Hazardous to our Health!

    What is Supercooled Liquid Water? Supercooled Liquid Water (SLW) refers to water droplets in a cloud that can stay in a liquid state at below freezing temperatures. If an airplane flies into these SLW droplets, icing on the wings and airframe can occur. ...

  • 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 ...

  • Micro Pulse LiDAR: A Critical Tool for Emissions Source Detection

    Micro Pulse LiDAR remote sensing data are used to calculate a highly accurate Planetary Boundary Layer (PBL) height to improve plume models that help assess emissions sources. ...

  • Geomembrana HDPE Liner for Gold Mine Tailings Pond in Indonesia - Case Study

    Geomembrana HDPE liner, also known as geomembrane HDPE liner, is the  very low permeability synthetic membrane liner used with geotechnical engineering related material so as to contain fluid or gas migration in a human-made project, structure, or system. BPM brand high quality Geomembrana HDPE liner is manufactured with ...

  • Micro Pulse Lidar: Perfect Tool for Atmospheric Research

    Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...

  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • ISO 14644 revisions summary

    Abstract The recent revision of ISO 14644-1 and-2 has introduced several changes for cleanroom classification and monitoring guidelines. This paper will highlight the major changes in the new ISO 14644-1 compared to the previous version, as well as the possible impact on the Pharmaceutical EU GMP Annex 1 and FDA Aseptic Processing ...

  • 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, ...

  • Stochastic models of oil spill processes

    This paper models the occurrence of an environmental accident as a stochastic event. In particular, the situation of an oil spill is explored. Characteristics of the ship operator, and the different types of the ship's operating environment determine a stochastic process governing the time patterns and size of spills. It is shown that both the time distribution of different types of oil spill and ...

  • Chemical Tank volume measurement

    In this application, Pulsar equipment replaced other ultrasonic gear which was not coping with the multiple echoes coming from a dome top tank. Level Star 110 non-contacting ultrasonic level measurement was supplied to a major chemical manufacturer, resolving a problem they had in the effective gauging of Sodium hydroxide. The Pulsar equipment replaced ultrasonic equipment previously supplied by ...
