Investigating the variability of the spatial-temporal pattern of rainfall, which can lead to climate change, due to its strong impact, is of interest to various scientists. For this purpose, after receiving the daily precipitation data of 27 stations for the period of 60 years (2010-1951), its quality and the total monthly precipitation and statistics necessary for the continuation of the resea...
Investigating of rainfall behavior in the spatial-temporal dimension and determining the tolerance thresholds of different geographical areas with respect to vegetation, animal life and human activities, is essential for any decision in the environment. Therefore, precipitation data of 27 stations were received from the Meteorological Organization during the 60-year period and After the data we...
Prostatic cancer mortality rates in Spain were analysed for the period 1951-1983 by age groups. Five year interval age cohort trends were also studied. A rising trend was seen over this period of time, although there has been some stabilisation during the recent past. Age cohort analysis shows a generation effect in those cohorts born before 1896, consistent with an increased exposure to enviro...
abstract in this study we have used the monthly data resulted from the calculation of temperature and precipitation for a 52-year period (1951-2003). the doubling effect of carbon dioxide ( ) on temperature and precipitation was modeled as the most important climatic parameters. the resulting hythergraph and ambrothermic models for tabriz indicate monthly increases of temperature and precipitat...
In this article, we present a comparative analysis of the demographic development and changes in settlement network over last 70 years territories exchanged 1951 between USSR Poland. We found that, within territory ceded to USSR, traditional pattern was restored renewed up 90%. Industrialization area resulted population growth reaching, at maximum, 40% greater numbers than 1939. The Poland feat...
Abstract. We analysed the instrumental seismicity in a sector of Po Plain (Italy) to define baseline for seismic monitoring new underground gas storage plant that will use depleted reservoir Cornegliano Laudense, near Lodi. The target area – square approximately 80 km × wide is commonly considered aseismic. period, 1951–2019, includes all available data. gathered P- and S-phase readings collect...
