Early Archaean rocks and geochemical evolution of the earth’s crust
Read more of: Early Archaean rocks and geochemical evolution of the earth’s crustRemnants of Early Archaean rocks (>FX3000 m.y. old) are reported from most continents. A critical review of the radiometric data shows that few of these are well authenticated and most […]

The cryopreservation ofChlorella
Read more of: The cryopreservation ofChlorellaFollowing growth under sub-optimal concentrations of nutrients, cells ofChlorella emersonii accumulated lipid and became more resistant to the damage caused by freezing and thawing. These results suggest that the factor […]

Generalized treatment of particulate scattering in Dobson ozone spectrophotometer calculations
Read more of: Generalized treatment of particulate scattering in Dobson ozone spectrophotometer calculationsIn the calculation of atmospheric total ozone from ultraviolet spectrometry, the particulate scattering term is usually regarded as a linear function of wavelength.

An insect invasion of Antarctica: the past, present and future distribution of Eretmoptera murphyi (Diptera, Chironomidae) on Signy Island
Read more of: An insect invasion of Antarctica: the past, present and future distribution of Eretmoptera murphyi (Diptera, Chironomidae) on Signy Island1. Rising human activity in Antarctica, combined with continued warming of the polar climate, means the risk of non‐native terrestrial species colonising and establishing in its biodiversity‐ and nutrient‐poor ecosystems […]
