In the north of Ireland ice advanced northwards onto the continental shelf from inland centres of dispersion at the last glacial maximum. We constrain the timing of three subsequent events by accelerator mass spectrometry C dating of marine microfaunas from muds at Corvish, County Donegal. Early and rapid deglaciation of the continental shelf off northwestern Ireland occurred before 17.1 k C ye...

introduction climate change happens due to abnormal changes of climate within the earth’s atmosphere and their consequences. one of the most significant effects of climate change is the irreversible damage to some floral species and forest ecosystems. tree species reflect the impact of climate changes on their ring width. generally, tree rings vary in size each year depending upon the environme...

An annually resolved and absolutely dated ring-width chronology spanning 4,500 y has been constructed using subfossil, archaeological, and living-tree juniper samples from the northeastern Tibetan Plateau. The chronology represents changing mean annual precipitation and is most reliable after 1500 B.C. Reconstructed precipitation for this period displays a trend toward more moist conditions: th...

S ome ancient and medieval historical dates we learn in school may stick in our minds: 1193 BC (the fall of Troy), 753 BC (the founding of Rome), AD 1 (the birth of Jesus), or AD 1066 (the battle of Hastings), to mention just a few. Most of us take these dates for granted, but are they correct? Anatoli Fomenko, a fellow of the Russian Academy of Sciences, finds them fictitious and promotes an a...

The recently shown two premises (Gurzadyan 2000), i.e. the absence of 56/64 year Venus cycle constraints, at the importance of the 8-year cycle in the Venus Tablet, stimulated new studies on the Chronology of the Ancient Near East (2nd millennium BC). The analysis by B.Banjevic using both premises, however, did not provide anchors of strenght similar to those of Ur III eclipses, while available...

OBJECTIVE To describe the eruption chronology of the first deciduous teeth in premature infants with birth weight less than 1500 g and to compare it according to gender and nutritional status at birth. METHODS Longitudinal study including 40 low birth weight premature infants of both genders. The tooth was considered erupted when the crown went through the gum and became part of the oral envi...

The Upper Fremont Glacier (UFG), Wyoming, is one of the few continental glaciers in the contiguous United States known to preserve environmental and climate records spanning recent centuries. A pair of ice cores taken from UFG have been studied extensively to document changes in climate and industrial pollution (most notably, mid-19th century increases in mercury pollution). Fundamental to thes...
