Observed beaming of terrestrial myriametric radiation
Read more of: Observed beaming of terrestrial myriametric radiationObservations by the Dynamics Explorer 1 satellite provide validation of the theory that terrestrial myriametric radiation is produced by the linear conversion of electrostatic upper hybrid waves to electromagnetic radiation […]

The magnetopause as a source of nonthermal continuum radiation
Read more of: The magnetopause as a source of nonthermal continuum radiationSecond only to auroral kilometric radiation as the Earth’s most prominent radio emission, magnetospheric nonthermal continuum radiation has been the subject of numerous observational and theoretical investigations. It has been […]

Io plasma torus and the source of jovian narrow-band kilometric radiation
Read more of: Io plasma torus and the source of jovian narrow-band kilometric radiationNarrow-band jovian kilometric radiation (nKOM) is distinguishable from broad-band jovian kilometric radiation (bKOM), both discovered by the Voyager spacecraft1–3, by its generally lower intensity, its more restricted range of centre […]

Morphometrics and ultrastructure of myocardial tissue in Notothenioid fishes
Read more of: Morphometrics and ultrastructure of myocardial tissue in Notothenioid fishesAntarctic fish of the family Channichthyidae (Icefishes) lack the respiratory pigments haemoglobin and myoglobin. The morphometrics and ultrastructure of the ventricular myocardium of a benthic icefish,Chaenocephalus aceratus has been compared […]

Muscle structure and differentiation in pelagic and demersal stages of the Antarctic teleost Notothenia neglecta
Read more of: Muscle structure and differentiation in pelagic and demersal stages of the Antarctic teleost Notothenia neglectaThe distribution and fine structure of muscle-fibre types has been determined for the pelagic fingerling and demersal adult stages of the antarctic teleost Notothenia neglecta Nybelin, collected from Signy Island, […]

Respiratory characteristics of muscle fibres in a fish (Chaenocephalus aceratus) that lacks haem pigments
Read more of: Respiratory characteristics of muscle fibres in a fish (Chaenocephalus aceratus) that lacks haem pigments1. Oxygen consumption, mitochondrial content and enzyme activities were determined in identified muscle fibre types of the ‘haemoglobin-less’ icefish Chaenocephalus aceratus Lonnberg. 2. Small bundles (2–12) of fast and slow […]

Species and sexual isolating mechanisms in sibling species of giant petrels Macronectes
Read more of: Species and sexual isolating mechanisms in sibling species of giant petrels MacronectesThe two sibling species of giant petrels Macronectes halli and M. giganteus are the dominant avian scavengers in the Southern Ocean ecosystem. They breed sympatrically at a number of sub-Antarctic […]
