This paper explains basic principles of ice interaction with shores comparing it to littoral drifts versus shores and drift barriers whether they function for ice or for sand or for both. A number of examples are given schematically outlining the two diff... see more

O diabetes mellitus (DM) inclui um grupo de doenças metabólicas resultante de disfunção na secreção e/ou ação da insulina. O diagnóstico de DM é definido com base na avaliação da glicemia de jejum(GJ) e hemoglobina glicada (A1C) que também informa a persi... see more

This study presents the experimental results of the equatorial ionospheric plasma drift zonal velocity obtained from Incoherent Scatter Radar (ISR) observations for 6 selective days in 2011 from Jicamarca, Peru. Our results indicate that the daytime drift... see more

F-region vertical velocities are derived from the ground-based ionosonde data for Ibadan (7.4°N, 3.9°E; dip 6°S:an equatorial station in the African zone), to study the general characteristics of electrodynamics of equatorialionosphere, such as their vari... see more
