run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...
Problem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity wa...
in the current study, the efficiency of starch and plantago ovata extract as coagulant aids is compared in water turbidity removal. the coagulant is ferric chloride and the experiments are run in two ranges of ph 7 and 8. the achieved results of turbidity removal in different turbidity levels of 100, 50 and 20 ntu caused by different concentrations of starch and p.ovata as coagulant aids besid...
AIMS To investigate the cause of turbidity in reconstituted lyophilised plasmas and to determine its effect on coagulometers. METHODS The turbidities of 20 normal plasmas and 16 reconstituted lyophilised plasmas were determined by comparing a 1 in 4 dilution in distilled water with a standard suspension in an Aminco Fluorocolorimeter (American Instrument Co) in nephelometric mode. The turbidi...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
Background & Aims of the Study: Drinking polluted water can transmit diseases, so potable water treatment is one of the most challenging and complex systems in countries. Continuous monitoring for evaluation process in water treatment plant is important. This study aims to investigate performance evaluation of Qom water treatment plant to remove turbidity and coliform in 2005 - 2014. Materia...
Background and Objective: Contamination of swimming pools’ water can lead to the transfer of different diseases to humans. The aim of this study was to investigate the water quality health indicators in Urmia swimming pools. Materials and Methods: In this cross-sectional study, 14 active covered swimming pools in Urmia city were chosen as census. The physical parameters such as pH, tem...
Isolation of a protective gamma-globulin fraction interfering with the zinc sulphate turbidity test.
The serum of a case of hyperglobulinaemia with negative thymol and zinc sulphate turbidity reactions was studied. The serum when added to pathological sera with high turbidity values brought about a marked reduction in the original turbidity values. Also, the serum did not give the usual copper proteinate precipitate when added to copper sulphate solutions. The anomalous protein fraction respon...
Automated data collection is essential to effectively measure suspended sediment loads in storm events, particularly in small basins. Continuous turbidity measurements can be used, along with discharge, in an automated system that makes real-time sampling decisions to facilitate sediment load estimation. The Turbidity Threshold Sampling method distributes sample collection over the range of ris...
