Superlinear dose dependence of thermoluminescence (TL) and optically stimulated luminescence (OSL) has been reported for many materials. The theoretical explanation has been ascribed to competition of either traps or recombination centers, during the excitation stage or during the read-out phase. There has been an account in the literature on superlinearity of OSL associated with merely one tra...

We investigate the potential of quartz-based OSL-dating for application to heated sandy sediments that are closely associated with remains charcoal production (charcoal kilns). This is particularly relevant post-1650 CE features, where 14C-dating lacks resolution. first document general OSL characteristics using large aliquots sand-sized quartz. Results from procedural tests indicate laboratory...

The Amazonia biome hosts upland closed and open vegetation ecosystems, in which the current biogeographical patterns relate to evolution of physical landscape. Therefore, understanding origin timing substrates supporting different ecosystems is indispensable for better comprehension Amazonian biogeography. Here we used quartz optically stimulated luminescence (OSL) thermally transferred (TT-OSL...

INTRODUCTION This chapter concludes the model of internet consumer behavior by describing some key moderating variables such as gender, need for cognition (NFC) and optimum stimulation level (OSL)(Figure 1).

To facilitate the research of mobile robot based odor source localization (OSL) and evaluate different strategies for the OSL, numerical simulation of odor plume in indoor ventilated environments is addressed. On the basis of the FLUENT software package, the 3-D wind field of an indoor ventilated environment is calculated using the Reynolds average approach, where the real wind velocity measure...

A formal specification method called RTOSL ('Real-Time Object Specification Logic') for the objectoriented approach is presented: We have extended the object specification logic OSL ([SernadasA et al. 92b]) so that real-time constraints can be included in a specification in an elegant way. Concepts of real-time temporal logic have been applied to this end. Characteristics of RTOSL (different fr...

This study presents preliminary results of research on pre-Angkorian canals near the ancient settlement of Angkor Borei in the southern Mekong delta of southern Cambodia. The canals have been mapped by aerial photograph interpretation and investigated in the field by hand auger drilling of two canal traces and trenching of one of these. Luminescence profiling through the canal infill successful...

The aim of this study was to evaluate the effect of EDTA, lysozyme, or the combination of EDTA and lysozyme on the antibacterial activity of ovotransferrin against Escherichia coli O157:H7. Ovotransferrin solutions (20 mg/mL) containing 100 mM NaHCO3 (OS) with added EDTA (2.0 or 2.5 mg/mL), lysozyme (1.0, 1.5, or 2.0 mg/mL), or both were prepared. The antibacterial activities of OS, OSE (OS+EDT...

Abstract Optically stimulated luminescence (OSL) dating of fine-grained (4–11 μm) fluvial sediments is rarely attempted but crucial for constraining the evolution mud-dominated floodplains. This study investigated applicability OSL to deposits in Mekong River, Cambodia based on a very young (<600 yr) point-bar riverbank succession and modern flood deposits. In succession, quartz provided you...

This review article gives a brief overview of some of the key legal challenges the OpenScienceLink, http://opensciencelink.eu (hereafter OSL) project faced with publishing biomedical research data online on an open access and re-use basis. Firstly, we give an overview of some of the key privacy challenges that the OSL project faced. Secondly, we analyse the intellectual property challenges that...
