Identification of mineral particles in pneumoconiotic lungs [PDF]

open access: yesJournal of Clinical Pathology, 1970
An extraction replication technique has been used for the study, by electron microscopy, of lung tissue from a number of different cases of pneumoconiosis. The technique provides a relatively simple means of studying the surface area of replicated tissues, and any foreign particles present which are either replicated or extracted from

Effects of Fiber and Copper Particles on Conductivity and Breakdown Characteristics of Natural Ester and Mineral Oil under DC Voltage

open access: yesEnergies, 2020
The converter transformer is a key equipment in high voltage direct current (HVDC) transmission system. Its oil-paper insulation system in the valve winding and outlet bushing experiences AC, DC, AC/DC, and transient impulse voltages simultaneously.

Chemical and Morphologic Characterization of Sylvite (KCl) Mineral from Different Deposits Used in the Production of Fertilizers

open access: yesAgronomy, 2022
In the present work, four (4) samples of sylvite (KCl) from different deposits in Canada, Belarus and Germany were analyzed in order to determine the differences between them in terms of chemical composition, morphology and impurities present.

Experimental study of the role of physicochemical surface processing on the IN ability of mineral dust particles [PDF]

open access: yes, 2011
During the measurement campaign FROST 2 (FReezing Of duST 2), the Leipzig Aerosol Cloud Interaction Simulator (LACIS) was used to investigate the influences of various surface modifications on the immersion freezing behavior of Arizona Test Dust (ATD ...

Calciprotein Particles [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2021
Hypercalcemia and hyperphosphatemia associate with an elevated risk of cardiovascular events, yet the pathophysiological basis of this association is unclear. Disturbed mineral homeostasis and the associated hypercalcemia and hyperphosphatemia may result in the formation of circulating calciprotein particles (CPPs) that aggregate the excessive calcium ...

Laboratory-generated mixtures of mineral dust particles with biological substances: characterization of the particle mixing state and immersion freezing behavior [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Biological particles such as bacteria, fungal spores or pollen are known to be efficient ice nucleating particles. Their ability to nucleate ice is due to ice nucleation active macromolecules (INMs).

‘Mineral particles and the environment’: introduction [PDF]

open access: yesMineralogical Magazine, 2003
The study of mineral particles has become increasingly important in the earth sciences, especially in the emerging field of environmental mineralogy. The Mineralogical Society highlighted this by dedicating its Spring Meeting in April 2001, held in Kingston University, Surrey, UK, to the subject.

Mineral particle disintegration model

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The study proposes mathematical model for reducing the size of mineral particles in crushing and grinding operations, which is a form of the reflected normal Gaussian – Laplace distribution. The study considers the distribution density modification of the mineral particles depending on the magnitude of the energy impact during ...

Characterization of individual ice residual particles by the single droplet freezing method: a case study in the Asian dust outflow region [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
In order to better characterize ice nucleating (IN) aerosol particles in the atmosphere, we investigated the chemical composition, mixing state, and morphology of atmospheric aerosols that nucleate ice under conditions relevant for mixed-phase clouds.
