BACKGROUND Asthma exacerbations attended in emergency departments show a marked seasonality in the paediatric age. This seasonal pattern can change from one population to another and the factors involved are poorly understood. OBJECTIVES To evaluate the association between meteorological factors and schooling with asthma exacerbations in children attended in the paediatric emergency departmen...
Introduction: Increasing or reducing the production of suspended particles depends on the important climatic and terrestrial characteristics of a region. One of the most important climatic factors affecting soil erosion is wind speed, so if the surface winds speed in a region exceeds the threshold of erosion, soil susceptibility to erosion and dust production increases. In contrast, the most im...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
[1] It took the solar polar passage of Ulysses in the early 1990s to establish the global structure of the solar wind speed during solar minimum. However, it remains unclear if the solar wind is composed of two distinct populations of solar wind from different sources (e.g., closed loops which open up to produce the slow solar wind) or if the fast and slow solar wind rely on the superradial exp...

The purpose of this study was to model the relationship between the frequency of dust storms and climatic variables in desert areas of Iran. For this purpose, climatic data of temperature (maximum and minimum), rainfall, wind speed (maximum and minimum), and their relationship with the number of days with dust recorded in 25 meteorological stations (statistical period since their inception unti...
Climate is one of the important natural factors that affect all stages of life, particularly human exploitation. Selection of the type of clothing, housing, cultures, architecture, civil engineering, and settlements are influenced by climatic factors. It can be said that the climatic circumstances of the surface of the earth and atmospheric circulation patterns have an important role in shaping...

Applying wind energy in Sistan region has been taken into consideration during different historical periods, especially during Qajar period. Varmal castle settlement which is located in Varmal village-environs of Hamoun County-is a Qajar period structure that has used wind power for various applications that resulted in a unique design and architecture. Applying wind power wisely for cooling, n...
