The Alpine Haselgebirge Formation represents an Upper Permian to Lower Triassic evaporitic rift succession of the Northern Calcareous Alps (Eastern Alps). Although the rocksalt body deposits are highly tectonised, consisting mainly of protocataclasites and mylonites of halite and mudrock, the early diagenetic history can be established from non-tectonised mudrock bodies: Cm-sized euhedral halit...

Numerical investigation of gravity flow of granular solids in a hopper through orifices of different shapes has been conducted using the discrete element method. The simulations are validated by comparing with the experimental results for rapeseed cases. It is observed that with orifices of the same area the flow rate decreases in the order of circle, square, rectangle and triangle, which is si...

We study the spontaneous nucleation and growth of sodium chloride crystals induced by controlled evaporation in confined geometries (microcapillaries) spanning several orders of magnitude in volume. In all experiments, the nucleation happens reproducibly at a very high supersaturation S ∼ 1.6 and is independent of the size, shape, and surface properties of the microcapillary. We show from class...

PTFE is often used in various fields because of its excellent properties such as low coefficient friction, heat resistance, and chemical resistance. On the other hand, non-granulated fine powder agglomerates easily tends to fibrillate, therefore, it difficult supply continuously with high accuracy. The purpose research develop a device that can accurately powder. authors propose new method whic...

The idea of monomiality traces back to the early forties of the last century, when J.F. Steffensen, in a largely unnoticed paper [1], suggested the concept of poweroid. A new interest in this subject was created by the work of G. Dattoli and his collaborators [2], [3] It turns out that all polynomial families, and in particular all special polynomials, are essentially the same, since it is poss...

A 2 x 3 x 4 factorial field experiment was established to determine the interaction among a nematode, an insect, and three weed species on soybean in 1983-86. Low (nematicide treated) or high (untreated) population densities of the soybean cyst nematode (SCN), Heterodera glycines, and 0, 30, or 70% main stem girdling by the threecornered alfalfa hopper (TCAH), Spissistilus festinus, were combin...

This talk re-examines some of the evolving interaction between hyperbolic geometry and low-dimensional topology, focussing in particular on some contributions of Murray Macbeath to surface topology.

Cyclone separators are active filtering devices suitable for a variety of industrial applications from conventional cutting oil pumps to recycling liquids. Since the vortex flow inside cyclones is highly complicated, performance and patterns these filters should be thoroughly researched. Liquid–solid mostly use water. Numerical studies on using higher-viscosity oils limited. In this study, liqu...
