the archaeological mound of sofalin south of the alborz mountains of northern iran (eastern rey plain) sheds considerablelight on at least four problems connected with the emergence of complex societies in this part of iran. the first, it helpsfill a chronological gap in an important archaeological sequence by revealing a previously unidentified late fourth andthird millennium b.c. sequence of ...

conclusions in this case series study, the fixation of different types of tibial plateau fractures with 3.5 mm simple non-locking and non-precontoured plates was associated with acceptable clinical, functional, and radiographic outcomes. based on the advantages and costs of these plates, the authors recommend using 3.5 mm simple plates for different types of tibial plateau fractures. results th...

In the aquatic genus Stuckenia, the wide geographic range of S. pectinata and S. filiformis make them suited for examination of topographic and climatic effects on plant evolution. Using nuclear ITS sequence and ten chloroplast sequences, we conducted comparative phylogeographical analyses to investigate their distribution regions and hybrid zones in China, and compare their phylogeographical p...

This paper presents a novel method to estimate active layer thickness (ALT) over permafrost based on InSAR (Interferometric Synthetic Aperture Radar) observation and the heat transfer model of soils. The time lags between the periodic feature of InSAR-observed surface deformation over permafrost and the meteorologically recorded temperatures are assumed to be the time intervals that the tempera...

The South Asian Monsoon and mid-latitude Westerlies are two important controls on Tibetan Plateau (TP) fresh water resources. Understanding their interaction requires long-term information on spatial patterns in moisture variability on the TP. Here we develop a network of 23 moisture-sensitive tree-ring chronologies from major juniper forests in a north-south transect on the eastern TP. Over th...

the expansion of grey- black pottery tradition in the iranian plateau, on the basis of iron age theory of cultural dynamism, was emerged by the end of the 2nd millennium bc. such a pottery tradition is regarded as a cultural sign to point migrants who entered in the iranian plateau from the northern outside of caucasus the major. according to the theory, the migrants passed the river valley of ...

Background: New organizational structures have changed rapidly, and progressive ladders have become short and flat, so human resources in the organization have faced various threats, including the career plateau. Lack of attention to ethical criteria as a double factor in the management process can be one of the causes of career plateau. Therefore, the present study attempted to design and expl...

The evolution of plateau monsoons is essential to synoptic climatology processes over the Qinghai-Xizang Plateau. Based on ERA-Interim Reanalysis data covering 1979–2014 from the European Centre for Medium-Range Weather Forecasts (ECMWF), we propose a new plateau monsoon index (ZPMI) that can effectively reflect the evolution of monsoons and compare this new index with the existing Plateau Mons...
