In this study we compare the mean annual sunspot numbers for six most recent solar cycles (19 to 24) with number of energetic proton events occurring in those years. Though individual exhibit quite strong correlations, when they are combined into a generic cycle result is very significant (ρ = 0.98). For 21 24 (when spacecraft observations have been regularly available), also investigate variat...

We estimated the galactic model parameters for a set of 20 intermediate-latitude fields with galactic longitudes 0 ≤ l ≤ 100 and 160 ≤ l ≤ 240, included in the currently available Data Release 6 (DR6) of the Sloan Digital Sky Survey (SDSS), to explore their possible variation with galactic longitude. The local space densities of the thick disc and halo are almost the same for all fields, 〈(n2/n...

The metastable crystallization phase of Fe-based alloys remains a popular topic in alloy research. α-Mn type was observed during the Fe80Zr10B10 amorphous alloy. ribbons prepared by melt spinning were annealed at different annealing temperatures and times. Different indicated that there large differences constitution. times preferentially nucleated relative to α-Fe phase. A long time resulted p...

Global climatological data are often evaluated in grids with perpendicular boundaries in a cylinder projection of the longitude and latitude circles of the earth. Typical datasets contain 10 6 to 10 8 values. Each dataset is organized in a diierent grid, according to the authors's preferences. When calculating the global radiation over the ocean, for example, it is essential that cloud data fro...

The general warming trend of the planet cannot be denied (the average global air temperature has increased by approx. 0.85°C between 1880-2012 (IPCC, 2013). direct consequence this is an increase in extreme weather events and hence climate risks. monitoring assessing precipitation, identifying physical laws governing its course order to able estimate forecast it future therefore great interest ...
