An overview of climate reconstructions considering summer air temperatures and effective precipitation is provided for northernmost Fennoscandia. During the earliest part of the Holocene (11,700–10,000 cal. BP), temperatures rose rapidly and were followed... see more

The identification of climatic relicts is seldom straightforward. These species are threatened owing to current climatic trends, which underlines the importance of carrying out ecological and biogeographic investigations of them. Here we introduce a novel... see more

This paper reviews published geochronological data on glacier fluctuations and environmental changes in central Patagonia (44° S - 49° S) from the Last Glacial Maximum (LGM) through to the Holocene. Well-dated glacial chronologies from the southern mid-la... see more

The aim of this study is to constrain the timing of the deglaciation process since the Last Local Glacial Maximum in HualcaHualca volcano and Patapampa Altiplano, located in the Andean Central Volcanic Zone. Nine 36Cl cosmogenic surface exposure dating of... see more

Recent reviews have highlighted the challenges posed by the Australian archaeological record for the concept of modern human behaviour. The archaeologically-visible components make only a limited, sporadic and generally delayed appearance in Australia, de... see more

Combined modulus and impedance spectra are employed in the present work to explore electrical inhomogeneity and carriers’ behaviors in a pure bentonite Moroccan clay based on equivalent circuit. It has been clearly observed that the electrical properties ... see more

Maintaining the stability of the air at the speed of pressurized pipe used for gas distribution lines are very unlikely to do the kind of windmill anemometer, cup anemometer and other tipes. One tipe of measuring instruments in accordance with these condi... see more

Heat exchangers are widely used in industry, however, raising their performance are important for the variety of applications. Consequently, efficiency improvement associated with low production cost is considered in this experimental work. The current st... see more
