De Groot proved that every group is the autohomeomorphism group of some metrizable space. A space is totally disconnected if every connected subset of it contains at most one point. We prove that every separable metrizable totally disconnected topological group is topologically isomorphic to the autohomeomorphism group of some separable metrizable space, when given the compact-open topology. It...

The Coastal area of Nazhvan is located at the riverside of Zayandehrūd River in the western part of Isfahan. In the gardens of this area which are mostly orchards, woodlands full of fruitless trees, owners have constructed architectural spaces and pavilions. One of the prominent architectural spaces within this territory is a mill known as “Asyāb-e Nazhvān or Hājjī”. There stands a two-floor pa...

The significant costs insert on mineral processes due to mill liner wear including the labor costs, price of material and shut down periods. Therefore, the study of this phenomenon is economically important to optimize the mill operating conditions and liner profile design to decrease the wear rate. There is no appropriate and applicable research on impact wear evaluation of mill liners. In the...

simulation of grinding circuits has being performed from 30 years ago and is also to be more complete and powerful approach with improvement of mathematical models which simulate various processing units/machines. the modeling and simulation of various mineral processing circuits are presently performed. in order to simulate the present grinding circuits of esfordi phosphate processing plant, a...

The wood biomass was liquefied by the pressurized hydrothermal method. The wood biomass powder in the different particle size, which was pulverized by a vibration mill, cutter mill and grinder, was used for the liquefaction. The liquefaction material was biomass slurry, which was prepared by mixing the wood biomass powder and water together (1:9). After filling the biomass slurry in a pressure ...

A MOP has five key steps: team formation; baseline analysis; benchmarking; project definition; implementation, monitoring and feedback. In the MOP approach, technical and business intellect is substituted for capital and equipment. Baseline analysis provides the current performance, variation of key production and process elements, and provides the data for cause and effect analysis. A MOP look...

There’s an old saying in Washington DC — making laws is like making sausage; you’re better off not knowing the details. Well, that same spirit often applies to the coverage of science news. The focus is on the succulent final product rather than the process required to get there. But science journalists have found the need to take a break from that approach with one big biology story: the tale ...

Rhythmic motor patterns, which underlie behaviors such as mastication, respiration and locomotion, are generated by specialized neural circuits called central pattern generators (CPGs). Although CPGs can generate their rhythmic motor output in the absence of rhythmic input, these motor patterns are modified by rhythmic sensory feedback in vivo. Furthermore, although the importance of sensory fe...
