Evolution of grain size distribution in galactic discs [PDF]
Astronomy & Astrophysics, 2020 Context. Dust is formed out of stellar material and it is constantly affected by different mechanisms occurring in the interstellar medium. Depending on their size, the behaviour of dust grains vary under these mechanisms and, therefore, the dust grain size distribution evolves as part of the dust evolution itself.

PLoS ONE, 2021 The grain size analysis plays a significant role in any geotechnical study. The grain size analysis, by means of sieving, is usually used for coarse material of particle size > 75 μm.

Measurement of Grain Size Distributions [PDF]
Microscopy and Microanalysis, 2015 ASTM standard E1181 discusses the characterization of duplex grain size microstructures and establishes a number of category types. There are various ways to characterize grain structures, including both manual and automatic image analysis approaches based upon either lineal or areal analysis of the grains.

Comparative analysis of starch grain size distribution in winter triticale samples
Plant Varieties Studying and Protection, 2016 Purpose. Determination of the possibility to differentiate triticale samples by starch grain size and identify samples with a minimum size of granules that have a significant positive correlation with the efficiency of the starch transformation into ...

Characterization of sand boils with grading entropy [PDF]
Zbornik Matice Srpske za Prirodne Nauke, 2012 Grain size and grain distribution by size are dominant factors determining soil behaviour. The shape and position of a grain distribution curve contain implicit information about the propensity of sand boiling or piping at flood conditions. The author

Investigation of Full-field and Mean-field Models for Pure Grain Growth Simulations
Hittite Journal of Science and Engineering, 2021 Mean-field approaches are commonly used in the simulation of grain growth in metals as they are easier to implement. However, mean-field models only track the evolution of average grain diameter as a function of temperature and time, while they neglect ...

Size Distribution of Grains Growing by Thermal Grain-Grain Collision [PDF]
Progress of Theoretical Physics, 1975 The time variation in the size distribution of dqst grains is. investigated for the case where the grains are in thermal motion under the impact of ambient gas molecules and they are growing by sticking in grain-grain collisions. The growth of grains in this manner may be expected to occur in .highly dense interstellar .clouds (or protostars) and ...

Revealing grain coarsening and detwinning in bimodal Cu under tension
Reviews on Advanced Materials Science, 2021 Metals with a bimodal grain size distribution have been found to have both high strength and good ductility. However, the coordinated deformation mechanisms underneath the ultrafine-grains (UFGs) and coarse grains (CGs) still remain undiscovered yet.

Uniform grain-size distribution in the active layer of a shallow, gravel-bedded, braided river (the Urumqi River, China) and implications for paleo-hydrology [PDF]
Earth Surface Dynamics, 2018 The grain-size distribution of ancient alluvial systems is commonly determined from surface samples of vertically exposed sections of gravel deposits.

Species distribution model transferability and model grain size – finer may not always be better
Scientific Reports, 2018 Species distribution models have been used to predict the distribution of invasive species for conservation planning. Understanding spatial transferability of niche predictions is critical to promote species-habitat conservation and forecasting areas ...
