OSHA's Respirable Crystalline Silica standard for construction requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers. The standard provides flexible alternatives, which OSHA expects will be especially useful for small employers. Employers can either use the control methods laid ...

1.. IntroductionThe fractional crystallinity of a semi-crystalline polymer is one of its most important physical parameters in that it reflects the morphology and determines mechanical properties, in that the Young modulus, yield stress, fatigue response and impact strength increase progressively with crystallinity [1].There is also a general tendency to …

This prompted the use of structural diagrams mapping to predict the structure of crystalline material 26,27,28,29,30,31,32,33. However, structural diagrams are heavily empirical and limited in scope.

In metals, conductivity occurs by transport of delocalised electrons through the crystalline lattice, under the influence of an applied electric field. The conductivity is …

To expedite new molecular compound development, a long-sought goal within the chemistry community has been to predict molecules' bulk properties of interest a priori to synthesis from a chemical structure alone. In this work, we demonstrate that machine learning methods can indeed be used to directly learn the relationship between …

Silica/Asphalt Milling Machine Partnership. The Partnership was established in 2003 to find a way to control workers' exposure to respirable crystalline silica during asphalt pavement milling in highway construction. Members of the Partnership include the National Asphalt Pavement Association, numerous paving contractors, all U.S. and foreign

A crystalline interface is located roughly in coincidence with its middle plane. Periodic boundary conditions are imposed on the four side surfaces of the domain Ω, while flux-free boundary conditions are imposed on its two ends. The PD source terms K α of Eq. (2) are confined within a small region in Ω as shown in Fig. 9. Such a setting ...

Abstract When monosized granular matter is subjected to continuous mechanical disturbance, crystallization can be observed. The granular crystallization process remains elusive and difficult to capture and forecast because of the complex interactions of particles and long periods of evolution. This study aims to establish a …

In addition, the gas flow geometry was designed to achieve good stability of the temperature. as a consequence, single crystalline SiGe with Ge content up to 0.2 was achieved [2]. Yonenaga et al. have intensively studied the CZ growth of Si 1– x Ge x in the whole range of Ge content, and obtained single crystals for 0 < x < 0.1 and 0.85 < x ...

A more common type of detector, known as the charge-coupled device (CCD) detector (Figure 7.3.9, can be found in many XRD machines, due to its fast data collection capability. A CCD detector is comprised of numerous radiation sensitive grids, each linked to sensors that measure changes in electromagnetic radiation.

Abstract. A comparison of the analysis of respirable crystalline silica direct-on-filter methods using X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy was undertaken using 253 real workplace air samples from road construction and tunnelling, coal mining, and kitchen benchtop manufacturing in Australia.
