thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
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...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
A new analysis method is introduced for investigating whether major flares are clustered in certain fixed regions of the Sun in rigidly-rotating coordinate systems. This method is applied to analysis of major flares of solar cycles 19–23. Northern and southern hemispheres are separately analyzed, and it is found that longitude distributions of flares in the two hemispheres are different. Theref...

the hot charging of continuously cast slabs steel is usually considered an effective method to reduce theenergy consumption in the hot rolling mills. in this work the application and optimizing of hot charging ofcontinuously cast slab in mobareke steel company has been investigated. mathematical relationship betweenthe cooling time of the stack of slabs and its mass average temperature is descr...
introduction: hot flash affects approximately 75% of women with breast cancer. those who experience hot flashes have higher rates of sleep disorders, temper and lower quality of life than women with no hot flashes. the persent study was aimed to compare the effect of megestrol acetate with gabapentin on the severity of hot flashes in patients with breast cancer materials and methods: in a...
in recent decades, economic development and population growth in the world has led to the expansion of road networks. therefore the use of optimum methods for repairing and maintenance of these roads is considered as an important value. today one of the options in this regard, is the use of asphalt recycling technology. the present study which took place in the summer of 2015 in iran, lorestan ...
mahallat hot springs located in the northeast of mahallat, in central iran. there are 6 main hot springs namely shafa, abejoush, donbeh, soleimanie, hakim and soda. in this research, geology, physico-chemical characteristics and petrography of basement rocks of these hot springs have been investigated. the results show that hot springs have an average temperature of 45°c and acidic to neutral p...
