Although byssinosis in jute mill workers remains controversial, studies in a few jute mills in West-Bengal, India, revealed typical byssinotic syndrome associated with acute changes in FEV1 on the first working day after rest. The present study on 148 jute mill workers is reported to confirm the occurrence of byssinosis in jute mill workers. Work related respiratory symptoms; acute and chronic ...

Much work has explored animal-to-animal variability and compensation in ion channel expression. Yet, little is known regarding the physiological consequences of morphological variability. We quantify animal-to-animal variability in cable lengths (CV = 0.4) and branching patterns in the Gastric Mill (GM) neuron, an identified neuron type with highly-conserved physiological properties in the crus...

A study has been conducted on 198 employees of a steel-mill industry. These participants were examined for mucosal lesions in the oral cavity and including the commissures and vermillion borders of the lips. The prevalences of 16 types of lesions are reported.

In this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of Sarcheshmeh copper complex was studied. The comminution circuit of this plant includes one SAG mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. The goal of this work was to calcu...

The steel mill slag (SMS) production in converter furnaces is one of the main by-products generated during production. This waste material usually composed different metal oxides that include basic cations such Ca, Mn, and Mg. These can favor alkalinity a heavy metals removal when they are partially dissolved contaminant solution as acid mine drainage (AMD). work aims to study potential use SMS...

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...
