TL;DR: In this article, a vertical flash pipe (1), with a classifier (4) located at the end of the flash pipe, with a collecting pipe (6) for recycled granular material after the classifier, and a discharge pipe (11) for the classified granular materials, was used for heat treatment, especially for drying, where a level indicator (8, 8a) was defined for the collecting pipe and a regulator (18) was activated by the measured value and acting upon the discharge device (rotary valve 9) and/or the classifiers (
Abstract: of EP00597831. Apparatus for heat treatment, especially for drying, a granular material in a gas stream, with a vertical flash pipe (1), with a classifier (4) located at the end of the flash pipe, with a collecting pipe (6) for recycled granular material after the classifier, and a discharge pipe (11) for the classified granular material, with a discharge device (9) at the end of the collecting pipe, and with a recycling pipe (10) from the discharge device to the flash pipe, characterized by a level indicator (8, 8a) for the collecting pipe (6) and a regulator (18) actuated by the measured value and acting upon the discharge device (rotary valve 9) and/or the classifier (4).

TL;DR: In this paper, a nuclear power member includes: a core part consisting of an aggregate of a graphite granular material; and a cover layer covering the core part and consisting of a ceramic dense body.
Abstract: PROBLEM TO BE SOLVED: To provide a nuclear reactor member capable of being stably used without generating swelling and creep-deformation, etc., even when directly exposed to neutrons without improving operating conditions and devices of a nuclear reactor.SOLUTION: A nuclear power member includes: a core part consisting of an aggregate of a graphite granular material; and a cover layer covering a core part and consisting of a ceramic dense body. Graphite affected by neutron irradiation is used in the state of an aggregate of a granular material and does not affect a shape and size of the nuclear reactor member even when swelling and creep deformation, etc., are generated since the granular materials are not bonded to each other. The nuclear reactor member has a cover layer covering a core part and consisting of the ceramic dense body. Since the cover layer consisting of the dense body has durability higher than that of the graphite to neutron-irradiation, the shape and size of the nuclear reactor member are hardly affected.

TL;DR: In this article, a 2D simulation of 896 "quartz" disks, with diameters of 0.20, 0.25 and 0.30mm, was produced by self-gravity sediment.
Abstract: The extensive use of granular materials as roadbeds accelerates the study of sand behavior under cyclic loading. While several studies have been done on sand deformation under cyclic loading, little information is available on the explanations for this behavior. By discrete element method (DEM) simulation, this paper offered a preliminary insight into particles interaction of loose sand which controls the material’s stress-strain behavior. A 2-D ‘sample’ of 896 ‘quartz’ disks, with diameters of 0.20, 0.25 and 0.30mm, was produced by self-gravity sediment. Then it was K0 loaded to t’ = 127 kPa, at which point, the sample started to be cyclically loaded for 5000 cycles when t’ kept constant. Cyclic amplitudes varied from 0.02 to0.04 t’. Increasing strain accumulation with increased number of cycles was observed. For smaller cyclic amplitude, strain accumulation increased smoothly, but for larger one, strain accumulation increased erratically after a large number of cycles. The coordination number variation during cycling load was considered to be responsible for this phenomenon. Induced anisotropy was observed, and it could be explained by deviatoric fabric analysis
