This paper aims to provide an overview concerning the optically stimulated luminescence OSL dating method and its applications for geomorphological research in France. An outline of the general physical principles of luminescence dating is given. A case study of fluvial sands from the lower terrace of the Moselle valley is then presented to describe the range of field and laboratory procedures required for successful luminescence dating. The paper also reviews the place of OSL dating in geomorphological research in France and assesses its potential for further research, by focusing on the diversity of sedimentary environments and topics to which it can be usefully applied. Hence it underlines the increasing importance of the method to geomorphological research, especially by contributing to the development of quantitative geomorphology. They are now largely used to date not only palaeontological or organic remains, but also minerals that characterise detrital clastic sedimentary material. The most common methods applied to minerals are cosmogenic radionuclides, electron spin resonance ESR and luminescence techniques. The latter were first applied to burned minerals from archaeological artefacts [thermoluminescence TL method]. Improvements of this technique led to the development, for more than twenty years, of the optical dating method [commonly referred to as Optically Stimuled Luminescence OSL ] which is now applied to sediments from various origins Wintle, The aim of this paper is to provide people involved in geomorphological research a global overview about the principles and procedures of optical dating, from the field sampling to the age interpretation.

During this unique stage in your life, you will feel a lot of excitement, along with the awkwardness caused by the changes in the body that are totally out of your control. In a few weeks, none of the clothes in your cherished wardrobe will fit! Of course you need maternity wear, but you would like to look as smart and fashionable as you always do. Neither do you want to wear the hideous, low-quality clothes with unflattering styles.

USNR is a leading supplier of systems for the manufacture of engineered wood products using RF gluing technology, dating back several decades. Glue molecules are alternately attracted to one electrode or the other and become heated by the friction generated by this molecular agitation. Thermosetting glues become cured within seconds of reaching the elevated temperature, so glued joints can be handled in minutes instead of hours or days.

Another advantage is the glue begins curing throughout the joint instead of working in from the outside surfaces. For dimensional lumber sizes, hot oil or steam-heated platens would take much longer for the heat to get to the middle of the joint. Gruen-Wald Laminates orders RF fingerjoint tunnel.

In this paper we use a recently developed radioluminescence (RL) attachment to the Risø TL/OSL reader to test the InfraRed-RadioFluorescence (IR-RF) dating.

The infrared radiofluorescence IR-RF dating technique was applied to eight fluvial samples that were collected from two sediment cores at the Heidelberg Basin located near Viernheim and Ludwigshafen in southwest Germany. Based on the IR-RF derived ages of the samples it was possible to establish a chronological framework for the Mid-Pleistocene fluvial deposits of the Heidelberg Basin.

The results allow us to distinguish between four main periods of aggradation. Hence, the measured IR-RF ages clearly point to a deposition during the Lower Saalian period OIS 9—8 whereas earlier studies assumed a Cromerian age for the sediments of the Upper Interlayer based on pollen records and also mollusc fauna. The new IR-RF dataset indicates that significant hiatuses are present within the fluvial sediment successions. In particular the Eemian and Upper Saalian deposits are missing in this part of the northern Upper Rhine Graben, as the ka deposits are directly overlain by Weichselian fluvial sediments.

It is obvious that time periods of increased fluvial aggradation were interrupted by time periods of almost no aggradation or erosion which should have been mainly triggered by phases of increased and decreased subsidence of the Heidelberg Basin.

Their event-based e. Our contribution evaluates the potential of a particular luminescence dating method, called infrared-radiofluorescence IR-RF to track Middle Pleistocene transport processes. IR-RF is applied to potassium feldspar and was already proposed by Trautmann et al. IR-RF is believed to significantly enhance the temporal range back to the Middle Pleistocene of luminescence dating techniques.

However, due to a lack of commercially available measurement equipment and doubts raised on its overall reliability, IR-RF based chronologies are scarce e. While the previous results show the potential of IR-RF, differences between age results, obtained with other trapped charge dating methods ESR, OSL and believed resulting from a complex sedimentation process, could not be fully resolved.

Our study compares age results from ‘conventional’ IR-RF dating, with age results from the spatially resolved measurements. Our contribution will outline the potential and the limits of the different approaches and discuss the implications for quantifying the palaeoenvironmental history.

Kodak 35 RF is a 35mm film rangefinder camera made by Eastman Kodak and produced between It is used by collectors to differentiate this model from the original Kodak 35 , which lacks a rangefinder. The camera is basically a Kodak 35 with the addition of a new cover containing a fixed viewfinder, film counter, wind and rewind knobs, and the separate rangefinder window. The rangefinder was incorporated in response to the incredible marketing success of the Argus C series. It is quite accurate and easy to use.

As this was almost double the price the Argus C3, it is easy to see why the Kodak 35 Rangefinder model suffered from lackluster sales.

Research among adults has shown that younger age is a consistent risk factor for experiencing and perpetrating intimate partner violence. However, no representative epidemiologic studies of lifetime prevalence of dating violence among adolescents have been conducted. After controlling for the effects of potentially confounding demographics and risk behaviors, data from both surveys indicate that physical and sexual dating violence against adolescent girls is associated with increased risk of substance use eg, cocaine use for , odds ratio [OR], 4.

Methods: A retrospective cohort study of 17, adult health maintenance organization HMO members who completed a survey about childhood abuse and household dysfunction, as well as their health.

We used logistic regression to examine the relationships between ACE score and six health problems depressed affect, suicide attempts, multiple sexual partners, sexually transmitted diseases, smoking, and alcoholism across four successive birth cohorts: , , , and Conclusions: Growing up with ACEs increased the risk of numerous health behaviors and outcomes for 20th century birth cohorts, suggesting that the effects of ACEs on the risk of various health problems are unaffected by social or secular changes.

Research showing detrimental and lasting neurobiologic effects of child abuse on the developing brain provides a plausible explanation for the consistency and dose-response relationships found for each health problem across birth cohorts, despite changing secular influences.
