Water sources and mixing in riparian wetlands revealed by tracers and geospatial analysis
Authors: Lessels Jason S. , Tetzlaff Doerthe , Birkel Christian , Dick Jonathan , Soulsby Chris 
Published: December 2015

AbstractMixing of waters within riparian zones has been identified as an important influence on runoff generation and water quality. Improved understanding of the controls on the spatial and temporal variability of water sources and how they mix in riparian zones is therefore of both fundamental and applied interest. In this study, we have combined topographic indices derived from a high‐resolution Digital Elevation Model (DEM) with repeated spatially high‐resolution synoptic sampling of multiple tracers to investigate such dynamics of source water mixing. We use geostatistics to estimate concentrations of three different tracers (deuterium, alkalinity, and dissolved organic carbon) across an extended riparian zone in a headwater catchment in NE Scotland, to identify spatial and temporal influences on mixing of source waters. The various biogeochemical tracers and stable isotopes helped constrain the sources of runoff and their temporal dynamics. Results show that spatial variability in all three tracers was evident in all sampling campaigns, but more pronounced in warmer dryer periods. The extent of mixing areas within the riparian area reflected strong hydroclimatic controls and showed large degrees of expansion and contraction that was not strongly related to topographic indices. The integrated approach of using multiple tracers, geospatial statistics, and topographic analysis allowed us to classify three main riparian source areas and mixing zones. This study underlines the importance of the riparian zones for mixing soil water and groundwater and introduces a novel approach how this mixing can be quantified and the effect on the downstream chemistry be assessed.
Relevance Theory and Second Language Acquisition
Authors: Foster‐Cohen Susan 
Published: December 2015

Abstract
Relevance theory (RT) is an account of how hearers interpret (and by implication how speakers design) verbal and nonverbal communications. The roots of RT are in Grice's account of the pragmatics of utterance interpretation; but whereas Grice argues for a cooperative principle that forms a compact between speakers and hearers and four maxims that drive speakers' message design (quantity, quality, relation, and manner), RT argues there is no need for either a cooperative principle or any of the maxims except (in a sense) the maxim of relation; although it is not understood as a maxim to follow but rather an inherent characteristic of human mental processing.
Metall‐Ligand‐Schwingungen in den Infrarot‐Absorptionsspektren von Komplexen mit leichten Zentralatomen und Sauerstoffkoordination: II. Bor‐ und Kohlenstoffverbindungen
Authors: Funck Ernst 
Published: December 2015

AbstractIn den IR‐Spektren mehrerer Borkomplexe mit vierzähliger Koordination werden (teilweise mit Hilfe des 10B/11B‐Isotopeneffekts) die antisymmetrischen Valenzschwingungen des BO4‐Tetraeders zugeordnet. Die bei Td‐Symmetrie dreifach entartete Schwingung ist meistens aufgespalten, manchmal in beträchtlichem Maße. Das untersuchte Material ergibt eine mittlere Wellenzahl von 1030 cm−1. Der Vergleich der Borverbindungen mit einigen isoelektronischen Kohlenstoffverbindungen ergibt für die entsprechenden Schwingungen der CO4‐Gruppe einen etwas höheren Wert von 1110 cm−1. Das entspricht den Verhältnissen bei Verbindungen des Bors und Kohlenstoffs mit zwei‐ und dreizahliger Koordination.

Authors: Meyer Bernd D. , Dreeskamp Herbert , Sommer Udo 
Published: December 2015

AbstractDie Austauschgeschwindigkeiten der Hydroxyl‐ und Carboxyl‐Protonen RM und RC methanolischer Formiatpuffer bei 25°C wurden durch Protonenresonanzspektren bei Hochauflösung und langsamem Durchgang untersucht. Dem Methanol wurden zur Feld‐Frequenz‐Stabilisierung 20 Vol.‐% Benzol und zur Kontrolle des Magnetfeldes 5 Vol.‐% Cyclohexan zugesetzt. Bei der Berechnung der tatsächlich vorhandenen Ameisensäure‐ und Formiat‐Aktivitäten x und y wurde die Verunreinigung des Lösungsmittels durch eine schwache Base (0,5 ± 0,1 ppm NH3) berücksichtigt. Folgende kinetischen Terme tragen zu RM bei: a = 10 ± 5[mol/sec] (unkatalysierter Austausch);bx/y mit b = 136 ± 36 [mol/1sec] (H+‐Katalyse); cy/x mit c = 0,50 ± 0,39 [mol/1sec] (OR−‐Katalyse); ixy mit i = (7,27 ± 0,17) ± 108 [1/mol sec] (termolekularer, vom Kation unabhängiger Austausch unter Beteiligung von einem Molekül Ameisensäure, einem Molekül Formiat und ni = 0,91 ± 0,19 Molekülen Methanol); hx2 mit h = (3,6 ± 1,6) ± 105 [1/mol sec] (cyclischer Austausch unter Beteiligung von Methanol und 2 Molekülen Ameisensäure); gy2/x mit g = (4,02 ± 0,88) ± 103 [sec−1]. Daneben wurden Beiträge zu RM gefunden, die linear oder quadratisch von y abhängen (fy und/oder jy2), zwischen denen aber nicht unterschieden werden konnte: f = (2,7 ± 1,1) ± 105 [sec−1] bei j = 0,j = (6,0 ± 2,4) ± 107 [1/mol sec] bei f = 0. Die gefundenen kinetischen Parameter werden mit Daten ähnlicher Systeme verglichen.

Diffusion of Tritium in Cold‐Worked Palladium
Authors: Sicking G. , Glugla M. , Huber B. 
Published: December 2015

AbstractThe mobility of hydrogen in cold‐rolled palladium specimens of different degree of plastic deformation was measured by employing the tritium tracer method. – In one set of experiments the temperature dependence of the diffusivity was determined at very low hydrogen to metal ratios below about 10−5. In another set of experiments the influence of precharged hydrogen on the tritium mobility was investigated at constant temperature. – The diffusion of tritium as a tracer in presence of hydrogen and within an imperfect lattice is treated on the assumption of local isotope distribution equilibrium between traps and interstitial sites. A trap binding energy of about 18 kJmol−1 is obtained. – By means of a self‐consistent evaluation of the experimental data also the trap binding entropy, the concentration of traps, and the separation factor of the isotope distribution equilibrium is determined. – It is found that tritium is enriched in interstitial positions. The concentration of traps is doubled on going from 30% to 50% of deformation. The localized vibrations of tritium in trap sites are found to be distinctly softer than in interstitial positions. – We suggest dislocation cores and sites close to dislocation cores as operating traps. The interaction energy between hydrogen and dislocation traps is discussed in connection with the misfit energy of hydrogen in metals.
Structure of Liquid Chloroform. A Comparison between Computer Simulation and Neutron Scattering Results
Authors: Dietz W. , Heinzinger K. 
Published: December 2015

AbstractThe intermolecular structure functions for liquid chloroform of various isotopic composition have been calculated from an MD simulation. Good agreement was found with the x‐ray measurement and four of the five experimental neutron structure functions. Strong disagreement, however, exists between the atom atom correlation functions derived from the neutron scattering experiments with the isotopic substitution method and the MD results. It seems possible that the atom atom correlation functions from the neutron scattering experiments, which are not without difficulties, might have suffered from experimental uncertainties.
Prediction of Mutual Solubilities of Heavy Components with Super‐Critical and Slightly Sub‐Critical Solvents: The Role of Equations of State and Some Applications of a Simple Expanded Lattice Model at Subcritical Temperatures
Authors: King M. B. , Kassim K. , Bott T. R. , Sheldon J. R. , Mahmud R. S. 
Published: December 2015

AbstractThe use (and limitations) of equations of state for collating and predicting liquid/liquid and liquid/dense fluid equilibria is discussed with reference to 15 binary pairs (including some new data for the Carbon dioxide/Hexadecane system at 60°C) and three ternary combinations. It is concluded that the estimation of some of the parameters required for these calculations would be difficult if the solute was a complex substance about which little was known apart from its structural formula. ‐ An alternative procedure is to apply activity coefficient expressions of the “regular solution” or UNIFAC type to each phase. Preliminary calculations along these lines are described and the physical basis for applying these methods under the relevant conditions is discussed. The “UNIFAC” approach in particular has been found to be encouraging, though the interaction parameters must be regarded as pressure dependent.
Diffusion of Liquid Hydrocarbons in Supercritical CO2 by Photon Correlation Spectroscopy
Authors: Saad Hani , Gulari Esin 
Published: December 2015

AbstractBinary diffusion coefficients of benzene and heptane in supercritical CO2 were measured by photon correlation spectroscopy. The measurements were carried out along isochores in the dense gas region at concentrations less than 5 mole percent hydrocarbon. The results of an analysis of data using mode‐mode‐coupling theory indicated that the exponent of the correlation length, ν = 0.67 ± 0.03 on the critical isochore. On the other hand, ν = 0.86 ± 0.05 was obtained on isochores that were not critical and the background contribution became significant.
Twenty Years Post‐genocide: The Creation of Mental Health Competence among Rwandan Survivors Through Community‐based Healing Workshops
Authors: Mahr Ines‐Lena , Campbell Catherine 
Published: December 2015

AbstractTwenty years after the genocide, many Rwandans still suffer from the psychological wounds of the past. The country's mental health agenda is based on individualised and psychiatric approaches that help some but cannot be provided on a large scale. Further, many reconciliation initiatives have been based on public testimonies, which have been shown to be potentially re‐traumatising, leading to calls for small‐scale community‐based approaches to healing, which constitute a middle way between individualised and public approaches. Drawing on the concept of ‘mental health competence’ (Campbell and Burgess, 2012), this study evaluates one such approach: the Life Wounds Healing workshops offered by the African Institute for Integral Psychology. Twenty‐one semi‐structured interviews were conducted with former workshop participants, staff members and the institute's founder to investigate their views on how these workshops can help genocide survivors. The results suggest that the workshops succeed in creating mental health competence by establishing a safe social space for people to open up, increasing people's critical understandings of the processes of pain — and potential for healing — that informs behaviour change, generating bonding social capital and offering participants' income‐generating possibilities.

Quadruplex DNA‐Stabilising Dinuclear Platinum(II) Terpyridine Complexes with Flexible Linkers
Authors: Ang Dale L. , Harper Benjamin W. J. , Cubo Leticia , Mendoza Oscar , Vilar Ramon , Aldrich‐Wright Janice 
Published: December 2015

AbstractFour dinuclear terpyridineplatinum(II) (Pt–terpy) complexes were investigated for interactions with G‐quadruplex DNA (QDNA) and duplex DNA (dsDNA) by synchrotron radiation circular dichroism (SRCD), fluorescent intercalator displacement (FID) assays and fluorescence resonance energy transfer (FRET) melting studies. Additionally, computational docking studies were undertaken to provide insight into potential binding modes for these complexes. The complexes demonstrated the ability to increase the melting temperature of various QDNA motifs by up to 17 °C and maintain this in up to a 600‐fold excess of dsDNA. This study demonstrates that dinuclear Pt–terpy complexes stabilise QDNA and have a high degree of selectivity for QDNA over dsDNA.
Siamese‐Twin Porphyrin Origami: Oxidative Fusing and Folding
Authors: Vogel Anastasia , Dechert Sebastian , John Michael , Brückner Christian , Meyer Franc 
Published: December 2015

AbstractOxidation of a nonaromatic Siamese‐twin porphyrin, a pyrazole‐containing expanded porphyrin with two porphyrinlike binding pockets, with a stoichiometric amount of the two‐electron, two‐proton oxidizing agent 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzochinone led to the formation of a single Npz‐Co‐Ph linkage between the pyrazole unit with a neighboring meso‐phenyl group, forming a pyrazolo‐ [1,5‐a]indole moiety. Repeated treatment with a second equivalent of the oxidant yielded a doubly N‐fused species, involving the second pyrazole moiety. The conversion products were characterized by variable‐temperature and multinuclear 1D and 2D NMR spectroscopy. The fusions strongly alter the conformation of the macrocycles, as shown by X‐ray diffraction analyses of all three compounds, eventually leading to a folded structure. UV/Vis and NMR‐spectroscopic investigations indicated the presence of highly delocalized but nonmacrocycle‐aromatic π systems. This behavior of the Siamese‐twin porphyrin in response to oxidation is in contrast to the behavior of related all‐pyrrole‐based expanded macrocycles that switch, by redox processes and protonation, between Hückel and Möbius aromatic states.
