The area along the eastern and southeastern margins of the Tengger Desert, NW China, which is sensitive to the summer monsoon variations, was selectedfor studying the environmental conditions surrounding the transition between Paleolithic foragers and Neolithic farmer/pastoral- ists. Short cores were obtained from four lake basins in the southwestern Tengger using a hand-driven piston coring device. Proxies from these cores were supplemented by ra- diocarbon ages obtained from lake sediment cores, shoreline features and spring mound deposits. Together these records provide evidence of millennial-scale climate change events from the Pleistocene-Holocene transition to the present. lake/wetland events, representing periods of more intensive summer monsoon, occur in the records at ～12.7-11.6, ～10.1, ～9.3, ～8.0, ～5.4, ～1.5, and ～0.8 ka BP. They do suggest that century- to millennial-scale climatic cycles are characteristic of the Holocene in the southeastern Tengger Desert although the chronology must be considered extremely tentative.

The effect of Argan plant extract （APE） on the corrosion of the steel in hydrochloric acid medium was studied using gravimetric, electrochemical polarization and impedance spectroscopy （EIS） measurements. Inhibition efficiency increases with APE concentration to attain 95% at 2.5 g/l. We note good agreement between gravimetric and electrochemical methods （potentiodynamic polarization and EIS）. Effect of temperature is also made in the 298-328 K range. Polarization measurements show also that APE act as a mixed inhibitor. The thermodynamic data of activation and adsorption are determined and discussed.
