  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • Blending of Log Normal Particle Size Data from Multiple Analyses into Continuous Data Set

    Abstract Image analysis is one method by which particle size may be measured. In many cases, it is considered the "gold standard" of particle size measurement and is often used to verify the results of other techniques. Sample particle size distributions are often broad, sometimes covering two to three decades of particle diameter. It is also common to analyze samples that are multi-modal ...

  • Application of particle damping for vibration attenuation in brake drum

    The mechanism of noise of brake is very complex. A particle damper can be introduced without changing the shape of the structure and the addition of mass, and it may be applied in extreme temperature environments where most conventional dampers would fail. However, previous particle damper designs have been based on trial-and-error experimentation. In this paper, the feasibility of an application ...

  • Particle shape factors and their use in image analysis - part 1

    Fine panicles are often characterized by their particle size and distribution as determined by various analytical instruments. Particle shape may be just as important as particle size. Particle shape, however, is often ignored or disregarded. Image analysis is a technique capable of measuring particle shape factors and providing valuable information. These shape factors may dictate the behavior ...
