The performance and ranking pattern of PV systems incorporated with solar trackers in the northern hemisphere

Renewable and Sustainable Energy Reviews, 2018
Energy produced from a typical PV panel with or without solar tracker is mainly dependent on the available solar irradiance. Interestingly, for some locations on nearly the same latitude in the northern hemisphere, the solar irradiance varies ...

Neogene aridification of the Northern Hemisphere

Geology, 2012
Neogene cooling and aridification in the Northern Hemisphere have long been recognized, but there are no studies comparing patterns of aridity gradients or differences between North America and Eurasia. Large herbivorous mammals are an excellent source for understanding large-scale environmental and climatic patterns because their molar crown height ...

Pleistocene Glaciations of the Northern Hemisphere

Geological Society of America Bulletin, 1929
Early Investigators As this has been announced to be a centenary year for glacial geology, a few words of explanation may be needed. The relevancy of 1928 as a centenary of glacial geology is based on the fact that two important investigations of glaciers date from the year 1828. That year marks the beginning of glacial studies by Jean de Charpentier,

Transfer of Northern Hemisphere Fall-out to the Southern Hemisphere

Nature, 1966
THE detonation of a low-yield nuclear device in Western China at 1900 h, October 16, 1964 (New Zealand time), was reported, and tests for barium-140 were included in our routine investigations of fall-out at Gracefield, Wellington (41° 14′ S., 174° 55′ E.), to identify debris from this test.

On the origin of northern and southern hemisphere grasslands

Plant Ecology, 2002
The origin of the grassy habit during the Eocene and the development of C4 grasses during the Miocene/Pliocene boundary are discussed before the origin of primary and secondary grassland in Eurasia and North America are discussed. A comparison shows that both Northern and Southern hemisphere primary grassland originated due to climatic changes to drier

The Breeding Seasons of Southern Hemisphere Birds in the Northern Hemisphere

Proceedings of the Zoological Society of London, 1938
Summary.Most Southern Hemisphere birds breed in the Southern Hemisphere spring and summer. Imported specimens of most of these species change their rhythm so as to breed in the northern spring and summer in the Northern Hemisphere.Some Southern Hemisphere birds breed in the Southern Hemisphere winter (or very early spring).
