Determination of representative height distributions of the electron concentration in the ionosphere
Read more of: Determination of representative height distributions of the electron concentration in the ionosphereMedian height distributions of electron concentration may be determined from ionograms by means of the composite ionogram technique of Wright, or by inserting tabulated parameters in the idealized model of […]

Signatures of the evolution of parthenogenesis and cryptobiosis in the genomes of panagrolaimid nematodes
Read more of: Signatures of the evolution of parthenogenesis and cryptobiosis in the genomes of panagrolaimid nematodesMost animal species reproduce sexually and fully parthenogenetic lineages are usually short lived in evolution. Still, parthenogenesis may be advantageous as it avoids the cost of sex and permits colonisation […]

Solar-cycle modifications of the effects of thermospheric winds on the height of the F2-layer over Antarctica
Read more of: Solar-cycle modifications of the effects of thermospheric winds on the height of the F2-layer over AntarcticaResults of analysis of the diurnal variations of hmF2 for Argentine Islands (65°15’S, 64°16’W) and Halley Bay (75°30’S, 26°40’W) are presented. It is shown that, for summer months, the diurnal […]

Thermodynamics of the interaction between ice shelves and the sea
Read more of: Thermodynamics of the interaction between ice shelves and the seaAn ice shelf is a floating ice sheet, attached to land where ice is grounded along the coastline. Nourished both by surface snow accumulation and by glaciers and ice sheets […]
