During the penultimate glaciation vast areas of the Alps were glaciated, with piedmont glaciers protruding into the foreland. In the easternmost part of the northward draining valleys of the Alps, the glaciers did not reach the foreland, but formed valley glaciers confined by the mountainous terrain. This also applies to the Ybbs valley, where samples for luminescence dating out of glaciofluvia...
Abstract Purpose This study compared the effects of offset loading (OSL) versus traditional (TDL) in bench press exercise on pectoral muscle thickness and strength over a 4-week mesocycle. Methods: Twenty male participants aged 18–45 years with at least 5 experience one-repetition maximum equal to or greater than their body mass were randomly assigned OSL TDL groups. Before after mesocycle, was...
لومینسانس برانگیخته با نور یکی از روش های مهم سن یابی مطلق مواد معدنی در عصر حاضر است. این روش در بررسی زمین لرزه های دیرین و فعالیت های زمین ساختی به ویژه در مناطق خشک و نیمه خشک نقش کلیدی دارد. با استفاده از این روش آخرین حادثه نورخوردگی رسوبات سن یابی می شود. با توجه به آنکه مغولستان دارای آب و هوای خشک است، روش لومینسانس در محاسبه سن رسوبات این منطقه مفید خواهد بود. رشته کوه های آلتایی در غ...
The objective of this paper is to review the use thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques as research tools in luminescence, particularly detect presence trapping centers that can degrade efficiency scintillators, shape properties persistent phosphors, storage phosphors dosimeters. A brief main analysis provided, followed by a discussion their limitations. ...
The well-known thermoluminescent material LiF:Mg,Cu,P (MCP) was previously shown to emit significant optically stimulated luminescence (OSL). In this paper, we investigate the rate of OSL recombination processes in MCP, expressed as effective lifetimes, using time-correlated single photon counting, context often referred time-resolved pulsed OSL. fell into two categories: (i) a dominant fast de...
optically stimulated luminescence (osl) is currently one of the most important dating methods. it dates the last exposure to sunlight. natural hazard evidences such as colluvial wedges, alluvial and fluvial sediments can be dated by osl. therefore, osl plays an important role in studies related to paleoseismology and tectonic activity, particularly in arid and semi- arid regions. the altai moun...
Localized electronic recombination processes in donor–acceptor pairs of luminescent materials have been recently modeled using a new kinetic model based on tunneling. Within this model, recombination is assumed to take place via the excited state of the donor, and nearest-neighbor recombinations take place within a random distribution of centers. An approximate semi-analytical version of the mo...
optically stimulated luminescence (osl) is currently one of the most important methods for dating minerals during the quaternary. this method plays an important role in studies related to paleoseismology and tectonic activities, particularly in arid and semi- arid regions. osl dates the last exposure to sunlight; therefore, it can directly find the ages of the coseismic or post seismic evidence...
The Galería de las Estatuas is a Mousterian site located within the Cueva Mayor-Cueva del Silo karstic system at Sierra Atapuerca (Burgos, Spain). This characterised by an important Upper Pleistocene stratigraphic sequence in which large number of lithic artefacts exhibiting clear affinities and rich assemblage faunal remains have been found. Additionally, this has yielded foot phalanx Neandert...
