Abstract Phase development during slag formation and reduction of Comilog Assmang ores in a setup that simulates the conditions an industrial SAF process under different coke bed temperatures, 1473 K (1200 °C), 1673 (1400 °C) 1773 K, (1500 was investigated. Graphite crucibles were utilized to contain charge as heating element induction furnace. A temperature profile established, cross-sectional...
in this work, studies of underground gas storage (ugs) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. results showed that di...
Insufficient electrical endurance of equipment and insulation failure against overvoltage is one of the most effective reasons for failure the power line. Lightening, switching or other disruptive parameters can cause line outage or distribution substation failure. There are different devices used to improve the safety, reliability, and power quality of the system. Surge arresters are one of t...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
background: tumor necrosis factor-beta or lymphotoxin-alpha (lt- α ), il-4 and il-10 are determining factors in immunity against bcg. allelic polymorphisms in the regulatory regions of their genes affect the rate of cytokine production and therefore, the host’s ability in bcg containment. objective : to study the prevalence of –590 (c/t) and –592 (c/a) allelic distribution of il-4 and il-10 ...
In many animal populations age distribution ha.~ been studied as a basic component of population structure. In plants, developmental plasticity and vegetative reproduction may mean that age distribution is less significant than size distribution, particularly in production processes occurring within populaJtions. Changes in size distribution with time and at different densities are discussed, w...
