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...
Introduction: Global warming is one of the most important environmental problems that have raised researchers’ attention. The present study aimed to analyze heat stress trends using the Wet Bulb Globe Temperature (WBGT) index in the country of Iran during the summer over a 30-year period. Materials and Methods: Daily summertime statistical data regarding mean temperature and mean relative humi...
the writers of this research have studied seven variables including: precipitation, relative humidity, sunny hours, temperature average, temperature minimum, temperature maximum and sea level pressure, at sanandaj air station during 1964-1994. sanandaj air station has nearly 10966 days of complete data for these variables. a principal component analysis (pca) has been applied on this data; then...
this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.
We compare the characteristics of dew at nearly the same latitude (42° 45° N) for the Mediterranean island of Corsica (Ajaccio, France) and two continental locations (Bordeaux, France, Atlantic coastal area; Grenoble, France, Alpine valley). Dew amount was measured on a horizontal reference plate made of Polymethylmethacrylate (Plexiglas) and placed at 1 m above the ground. Data are correlated ...
abstract background: heat is one of the most important of harmful agents in many working environments such as bakeries that can cause prevalence of diseases related to heat and falling of efficiency. aim of this study was exposure evaluation of isfahan bakers to heat stresses in their working environment through evaluation of relationship among wet bulb globe temperature index (wbgt) , oral tem...
Stochastic weather generators are widely used in different fields such as hydrological applications, environmental management and agricultural risk assessments. In this study, a popular stochastic weather generator, LARS-WG, was used in relation to reproduce observed statistical properties, including, means and variances of monthly precipitation, maximum temperature, minimum temperature and sol...
introduction prediction of thunderstorm is one of the most difficult issues in weather forecasting. deep convective clouds develop at small spatial and temporal dimensions about 1-10 km and 1-12 h. various thermodynamic parameters have been discovered over the past 40 years, according to data obtained by radiosounds. the capability of these indices in forecasting instability varies over time an...
Heat exchangers are commonly used in industrial fields such as air conditioning, petrochemical and agriculture-food industries. The design and utilization of a heat exchanger should fulfill some conditions of performance, economy and space requirement. The most widely operated heat exchangers make use of fin-and-tube configuration in association with the application of heating, ventilating, air...
