The atmospheric conditions above Dome A, a currently unmanned location at the highest point on the Antarctic plateau, are uniquely suited to astronomy. For certain types of astronomy Dome A is likely to be the best location on the planet, and this has motivated the development of the Plateau Observatory (PLATO). PLATO was deployed to Dome A in early 2008. It houses a suite of purpose-built site...

Despite recognition that nearly one-third of the 6300 amphibian species are threatened with extinction, our understanding of the general ecology and population status of many amphibians is relatively poor. A widely-used method for monitoring amphibians involves injecting captured individuals with unique combinations of colored visible implant elastomer (VIE). We compared VIE identification to a...

Groundwater plays a key role in maintaining the ecology and environment in the hyperarid Qaidam Basin (QB). Indirect evidence and data from sparse observation wells suggest that groundwater in the QB is increasing but there has been no regional assessment of the groundwater conditions in the entire basin because of its remoteness and the severity of the arid environment. Here we report changes ...

introduction the aim of this study was to compare the characteristics of deflection load of three kinds of nickel titanium closed coil springs. methods and materials this research was an experimental study. research sample contains three kinds of niti closed coiled springs (heavy, medium, light) from gac, 3m, and rmo factories. 10 springs with 9 mm length for each group (totally 90 springs) wer...

The current geological and tectonic setting of Iran is due to the ongoing convergence between the Arabian and Eurasian Plates, which resulted in the formation of the Iranian plateau, mountain building, extensive deformation and seismicity. The Iranian plateau is characterized by various domains including the continental collision and the oceanic plate seduction. Based on S receiver functions ar...

BACKGROUND Osteochondritis dissecans are typically located mainly on the femoral condyle, with reported but less common cases of patella involvement. In this case report, we reported a rare case of osteochondritis dissecans located on the medial tibial plateau. CASE PRESENTATION A 26-year-old Han Chinese woman presented with a lesion on her left medial tibial plateau. She was treated by arthr...

This study uses high-resolution, long-term satellite observations to evaluate the spatial scales of the climate variations across the Tibet Plateau (TP). Both land surface temperature and precipitation observations of more than 10 years were analysed with a special attention to eight existing ice-core sites in the TP. The temporal correlation for the monthly or annual anomalies between any two ...

The Tianshan Mountains play a significant role in the Central Asian flora and vegetation. Lagochilus has a distribution concentration in Tianshan Mountains and Central Asia. To investigate generic spatiotemporal evolution, we sampled most Lagochilus species and sequenced six cpDNA locations (rps16, psbA-trnH, matK, trnL-trnF, psbB-psbH, psbK-psbI). We employed BEAST Bayesian inference for datin...

two vessels from different sites of the iranian plateau, dating to the late 4th or early 3rd millennium bce are presented aspalaeotechnological case studies. in the fractures of the vessels’ walls, interfaces left by added clay parts (enhanced inthe two illustrations) are quite recognizable. it is proposed that in both cases potters, in order to construct the bases, usedto make bowls comparable...

palaeoclimatology is a basic approach for the neolithic archaeology. the world-wide climate changes during the holocene ca. 10th millennia bc was an introduction to the neolithic revolution and the emergence of early villages. early holocene climate oscillations changed the biogeography of iran. consequently, its temperature, fauna and flora had been changed during ca. 12800- 3500 bc; and final...
