TL;DR: In this paper, the authors make a strong case for the necessity to characterize both solid and liquid phases in order to analyze any aqueous mineral carbonation test results, and show that partial information about reaction products, such as liquid phase analysis without characterization of the associated solid phase, can easily lead to flawed conclusions.

TL;DR: In this paper, a method for increasing the optical measurement range in optical time domain reflectometers in which a fibre laser amplifier is used to amplify the optical time-domain reflectometer pulses launched into a waveguide is presented.
Abstract: Apparatus and a method for increasing the optical measurement range in optical time domain reflectometers in which a fibre laser amplifier is used to amplify the optical time domain reflectometer pulses launched into a waveguide. This apparatus and method have particular usefulness for branched local networks. The signal returning to the optical time domain reflectometer is amplified as well as the outbound signal.

TL;DR: In this paper, stable isotopes are used for the study of local diagenetic mechanisms, knowledge of which is a key to the understanding of the sedimentary record from geochemical and geophysical points of view.
Abstract: Lower Jurasssic argilo-limestones from a continental platform environment have been drilled at Montcornet in the Paris Basin (Andra, 1989). The isotopic analysis of calcite yield δ 13 C values between −3 and +1 %o, and δ 18 O between +21 and +27 ‰ Depletion in 13 C is caused by secondary crystallisation of calcite in a sulphate-reducing environment, where isotopically light dissolved inorganic carbon, resulting from organic matter mineralization, is added into the pore fluids. The depletion in δ 18 O results from the isotopic equilibrium between pore water and calcite, which is controlled by temperature, fluid/rock ratio and the δ 18 O of interstitial fluid. This study clearly shows that stable isotopes are a powerful tool for the study of local diagenetic mechanisms, knowledge of which is a key to the understanding of the sedimentary record from geochemical and geophysical points of view.

TL;DR: In this article, a spectral source model based on the k−2 dislocation distribution was proposed to estimate the high frequency levels of the Erzincan earthquake in Turkey using broadband accelerograms near the sources.
Abstract: Seismic‐hazard assessment at small scales requires the computation of realistic broad‐band accelerograms near the sources. Methods that use only natural records are often limited because of the limited data set. Among recently developed methods for source modelling, the spectral‐source model, based on the k−2 dislocation distribution seems particularly promising as it enables computation of synthetics for any source‐receiver distance and directivity configuration. The spectral model takes into account important source characteristics, such as stress drop and directivity effects predicting acceptable high‐frequency levels, whatever the station location (Bernard et al., 1996b). Firstly, some tests to explain the directivity properties of the model are presented, followed by the main results of a deterministic study carried out for the 1992 Erzincan earthquake, Turkey. Finally, results of a probabilistic study in the Moyenne‐Durance region (France) are used to demonstrate the ability of this method ...
