Optically Stimulated Luminescence (OSL) used in conjunction with optical fibres allows remote measurements of both dose and dose rate for the purpose of radiation protection in nuclear industry and medecine (radiology, radiotherapy), monitoring of installations (dismantling) as well as in process controls. Since 1995, two types of OSL systems have been developed by the Optical Measurement Labor...

Dating agricultural terraces is a notoriously difficult problem for archaeologists. The frequent occurrence of residual material in terrace soils and the potential for post-depositional disturbance mean that conventional artefactual and lab-based dating methods often provide unreliable dates. In this paper we present a new technique using luminescence field profiling coupled with OSL dating to ...

Reconstructing paleoenvironmental change from glacial geologic evidence in the Himalayas has been difficult because of the lack of organic material for radiocarbon dating and the problems of correctly identifying the origin of highly dissected landforms. Studies of the contemporary glacial depositional environments, and ancient landforms and sediments in the Hunza valley (Karakoram Mountains), ...

Recent exploratory efforts to reveal the evolution and the climatic history of Mars have shown that the planet is still active. The surface of Mars has been, and continues to be, shaped by fluvial, eolian and glacial processes. The timeframe of these events is, however, poorly established. We describe efforts and challenges to adapt optically stimulated luminescence (OSL) dating for robotic in-...

This paper describes an agent-based software package, called Mathematical Programming-based Multi-Agent Systems (MP-MAS), which builds on a tradition of using constrained optimization to simulate farm decision-making in agricultural systems. The purpose of MP-MAS is to understand how agricultural technology, market dynamics, environmental change, and policy intervention affect a heterogeneous p...

Motivated by the search of new materials for optically stimulated luminescence (OSL) dosimeters, magnesium aluminum spinels with different Mg:Al ratios were investigated. Powders prepared via co-precipitation method 1:2 (stoichiometric), 1.5:2 (MgO-rich) and 1:3 (Al2O3-rich) calcined at 1000 °C in air 2 h. A higher level structural disorder was found powders than single crystal as determined X-...

we have investigated an optically stimulated luminescence (osl) dating study in the nimbluk lakebed in khorasan, northeast iran. two samples of the lake-bed sediments from ~1 m below the land surface are successfully dated at 7.3-9.9 ka. all necessary experiments have been performed to choose the most suitable procedure for dating quartz extracts using single aliquot regeneration method (sar). ...
