Optimization of the MgS:Eu:Sm phosphor for potential use as an optically stimulated personnel dosimeter
… dosimeters. Optically stimulated luminescence (OSL) dosimeters are advantageous in that they provide a faster, isothermal dose measurement than conventional thermoluminescent dosimeters. The effects of activator concentration and chemical substituents are examined in order to increase OSL …

Characterizing the Durability of PF and pMDI Adhesive Wood Composites Through Fracture Testing
… strandboard (OSB), oriented strand lumber (OSL) and parallel strand lumber (PSL) for the DCB fracture method was assessed. The fracture resistance of PF was reduced significantly by the aging exposures. The fracture resistance of pMDI did not decrease after the 2-hour boil test. The DCB …

Investigating rates and mechanisms of lateral erosion in a small bedrock river using erosion pins, structure-from-motion photogrammetry, and optically stimulated luminescence dating: Konza Prairie, northeast Kansas
… Single-grain optically stimulated luminescence (OSL) dating of fluvial deposits overlying a strath terrace was used to determine the depositional age of fluvial deposits and infer the duration of lateral channel mobility during terrace occupation. Lateral erosion rates of limestone measured …

Sorting out ceramics : correlating change in the technology of ceramic production with the chronology of 18th and early 19th century western BaTswana towns
… method is optically stimulated luminescence (OSL), which determines the amount of time passed since a mineral grain was last exposed to heat or light. This research includes a pilot study in dating late Moloko sites by measuring OSL of quartz grains from furnace and midden features for which …

Late Quaternary sedimentary architecture and depositional history of the Monahans Dune Field, Winkler County, TX.
… derived from Optically Stimulated Luminescence (OSL) and Thermal Transfer (TT-OSL) Single Aliquot Regeneration (SAR) protocols on quartz grains from in-tact sediment cores. The stratigraphy and chronology of quartz grains from these cores document thirteen eolian deposition phases (EDPs). These …

Luminescence based chronologies on Late Pleistocene loess-palaeosol sequences: an applied-methodological study on quartz separates
… especially optically stimulated luminescence (OSL), is the leading dating approach for establishing chronologies on loess archives. Furthermore, the development of luminescence dating techniques on sediments is closely connected with the history of loess research and vice versa. As part of the …

Hydrogen Sulfide in Glaucoma: Delivery System, Hypotensive and Neuroprotective Effects
… New Zealand albino rabbits. A H2S donor, OSL-4, was found to lower IOP by 26%, comparable than the marketed drug timolol (27%). Pretreating OSL-4 with glutathione further decreased the IOP by 32.3%. Lastly, the neuroprotective effects of H2S on the bovine retina were evaluated with H&E, …
