The role of gestures in a teacher–student-discourse about atoms
Authors: Abels Simone
Published: June 2016

Recent educational research emphasises the importance of analysing talk and gestures to come to an understanding about students' conceptual learning. Gestures are perceived as complex hand movements being equivalent to other language modes. They can convey experienceable as well as abstract concepts. As well as technical language, gestures referring to chemical concepts can be a challenge for students and cause misunderstandings. The study presented here focuses on a chemistry teacher’s use of gestures in a discourse about atoms. The questions of interest are how the teacher uses certain gestures, if her intentions can be reconstructed and if students seem to understand the content-related gestures. Analysis is done by applying the steps of the Documentary Method. The results show that the teacher uses imagistic gestures, because of the assumption that students can remember and understand the abstract concepts of chemistry faster by using scaffolding in forms of visualisation. Challenges of using gestures to visualise abstract chemistry concepts are discussed.

PQ state space representation and its application to electromagnetic compatibility/incompatibility degree, influence degree, and PQ performance assessment
Authors: Yu Hao , Jia Qingquan , Dong Haiyan , Wang Ning
Published: June 2016

This study introduces power quality (PQ) state space representation to describe continuous PQ disturbances. A tolerance boundary is designed to represent the integrated disturbance tolerance of all equipment connected to electric power network, and the uncertainty of integrated disturbance tolerance is described with the cloud model. Electromagnetic compatibility and incompatibility degree indices are proposed to reflect the severity of PQ disturbances affecting the equipment. The influence degree index is defined to quantify the severity and impact scope of PQ disturbances. The uncertainty of equipment fault state is expressed by a fuzzy membership function. Subsequently, PQ performance is assessed according to equipment compatibility/incompatibility degree to PQ disturbances. Case studies on a 14‐bus distribution system are performed and analysed. Results reveal the effectiveness and reasonableness of the proposed indices in assessing equipment compatibility/incompatibility degree to PQ disturbances, influence of PQ disturbances on the equipment, and PQ performance.
Anträge auf psychosomatische Rehabilitation – Häufigkeit, Qualität und Befürwortungsrate
Authors: Ahnert J. , Schuler M. , Legner R. , Schmale R. , Berger H. , Vogel H.
Published: June 2016

Hintergrund: Der Anteil an psychischen Hauptdiagnosen hat bei den medizinischen Rehabilitationsleistungen der DRV in den letzten Jahren stetig zugenommen. Bisher existieren kaum Daten über Häufigkeit, Qualität und Befürwortungsquote von Anträgen auf eine psychosomatische Reha. Prüfärzte der DRV benötigen im Rehabilitationsantrag ausreichend Informationen über Rehabedarf, -motivation, -fähigkeit und -prognose eines Versicherten. Der ärztliche Befundbericht bei Reha-Anträgen von Patienten mit psychischer Hauptdiagnose wird oft durch den Hausarzt erstellt. Psychische Störungen werden von Hausärzten häufig fehlerhaft diagnostiziert.

Methodik: Bei der DRV Nordbayern und der DRV Bayern Süd wurden über 2 Wochen die prüfärztlichen Entscheidungen bei Reha-Anträgen im Rahmen einer prospektiven Aktenanalyse dokumentiert. Für jeden eingehenden Reha-Antrag wurden folgende Angaben notiert: psychische und somatische Hauptdiagnose/n, Vorliegen von Befundberichten, Angaben zu psychiatrischen/psychotherapeutischen Vorbehandlungen, nachträgliche Anforderung von weiteren Entscheidungsgrundlagen sowie die prüfärztliche Entscheidung.

Ergebnisse: Insgesamt konnten 1 366 Anträge (davon 81% Erstvorlagen) analysiert werden. 16,2% der Erstvorlagen stammen von Antragstellern mit psychischen Hauptdiagnosen. 44,0% dieser Anträge liegt nur ein Befundbericht vom Hausarzt bei. Der Anteil an nicht befürworteten (34,7%) und noch offenen Anträgen (27,2%) liegt bei Reha-Anträgen von Antragstellern mit psychischen Hauptdiagnosen höher als bei Antragstellern mit rein somatischen Hauptdiagnosen (19,6% nicht befürwortete, 12,7% offene Anträge) (χ2=79,8(4), p=0,001). Reha-Anträge von Patienten mit psychischen Hauptdiagnosen ohne Befundbericht vom Psychiater/Psychotherapeuten werden häufiger nicht befürwortet (45,3 vs. 32,3%) oder werden bei der Erstvorlage nicht entschieden (28,0 vs. 18,3%) (χ2=10,2(2), p=0,006). Unter Antragstellern, die bereits in psychiatrischer/psychotherapeutischer Vorbehandlung waren, zeigt sich bei Reha-Anträgen mit Befundbericht vom Hausarzt nur noch ein höherer Anteil an nicht entschiedenen Anträgen (35,7 vs. 18,2%). Bei nicht entschiedenen Anträgen mit Befundbericht vom Hausarzt wird am häufigsten (68,9%) noch ein Befundbericht vom Psychiater/Psychotherapeuten nachgefordert.

Schlussfolgerung: Um die Aussagekraft von Anträgen mit psychischer Erstdiagnose bzw. Anträgen auf eine psychosomatische Rehabilitation zu erhöhen und eine raschere Entscheidung und eine bessere Indikationsstellung zu ermöglichen, könnte es sinnvoll sein, Befundberichte von vornherein von Fachärzten für Psychiatrie oder Psychotherapeuten erstellen zu lassen.

Omnidirectional excitation of sidewall gap-plasmons in a hybrid gold-nanoparticle/aluminum-nanopore structure
Authors: Lumdee Chatdanai , Kik Pieter G.
Published: June 2016

The gap-plasmon resonance of a gold nanoparticle inside a nanopore in an aluminum film is investigated in polarization dependent single particle microscopy and spectroscopy. Scattering and transmission measurements reveal that gap-plasmons of this structure can be excited and observed under normal incidence excitation and collection, in contrast to the more common particle-on-a-mirror structure. Correlation of numerical simulations with optical spectroscopy suggests that a local electric field enhancement factor in excess of 50 is achieved under normal incidence excitation, with a hot-spot located near the top surface of the structure. It is shown that the strong field enhancement from this sidewall gap-plasmon mode can be efficiently excited over a broad angular range. The presented plasmonic structure lends itself to implementation in low-cost, chemically stable, easily addressable biochemical sensor arrays providing large optical field enhancement factors.

Silicon carbide (SiC) is a promising material for new generation electronics including high power/high temperature devices and advanced optical applications such as room temperature spintronics and quantum computing. Both types of applications require the control of defects particularly those created by ion bombardment. In this work, modification of optical constants of 4H-SiC due to hydrogen implantation at 180 keV and at fluences ranging from 1014 to 1016 cm−2 is reported. The depth dependence of the modified optical constants was extracted from coherent acoustic phonon spectra. Implanted spectra show a strong dependence of the 4H-SiC complex refractive index depth profile on H+ fluence. These studies provide basic insight into the dependence of optical properties of 4H silicon carbide on defect densities created by ion implantation, which is of relevance to the fabrication of SiC-based photonic and optoelectronic devices.
Generation of “gigantic” ultra-short microwave pulses based on passive mode-locking effect in electron oscillators with saturable absorber in the feedback loop
Authors: Ginzburg N. S. , Denisov G. G. , Vilkov M. N. , Zotova I. V. , Sergeev A. S.
Published: June 2016

A periodic train of powerful ultrashort microwave pulses can be generated in electron oscillators with a non-linear saturable absorber installed in the feedback loop. This method of pulse formation resembles the passive mode-locking widely used in laser physics. Nevertheless, there is a specific feature in the mechanism of pulse amplification when consecutive energy extraction from different fractions of a stationary electron beam takes place due to pulse slippage over the beam caused by the difference between the wave group velocity and the electron axial velocity. As a result, the peak power of generated “gigantic” pulses can exceed not only the level of steady-state generation but also, in the optimal case, the power of the driving electron beam.
Highly efficient and selective pressure-assisted photon-induced polymerization of styrene
Authors: Guan Jiwen , Song Yang
Published: June 2016

The polymerization process of condensed styrene to produce polystyrene as an industrially important polymeric material was investigated using a novel approach by combining external compression with ultraviolet radiation. The reaction evolution was monitored as a function of time and the reaction products were characterized by in situ Fourier transform infrared spectroscopy. By optimizing the loading pressures, we observed highly efficient and selective production of polystyrene of different tacticities. Specifically, at relatively low loading pressures, infrared spectra suggest that styrene monomers transform to amorphous atactic polystyrene (APS) with minor crystalline isotactic polystyrene. In contrast, APS was found to be the sole product when polymerization occurs at relatively higher loading pressures. The time-dependent reaction profiles allow the examination of the polymerization kinetics by analyzing the rate constant and activation volume as a function of pressure. As a result, an optimized pressure condition, which allows a barrierless reaction to proceed, was identified and attributed to the very desirable reaction yield and kinetics. Finally, the photoinitiated reaction mechanism and the growth geometry of the polymer chains were investigated from the energy diagram of styrene and by the topology analysis of the crystal styrene. This study shows strong promise to produce functional polymeric materials in a highly efficient and controlled manner.
Measuring the diffraction properties of an imaging quartz(211) crystal

Published: June 2016

A dual goniometer X-ray system was used to measure the reflectivity curve for a spherically bent quartz(211) crystal. An analysis of the dual goniometer instrument response function for the rocking curve width measurement was developed and tested against the actual measurements. The rocking curve was measured at 4510.8 eV using the Ti Kα1 characteristic spectral line. The crystal is the dispersion element for a high resolution spectrometer used for plasma studies. It was expected to have a very narrow rocking curve width. The analysis showed that we could measure the upper bound for the rocking curve width of the Qz(211) crystal. The upper bound was 58 μrad giving a lower bound for the instrument resolving power E/ΔE = 34 000. Greatly improved insight into the dual goniometer operation and its limitations was achieved.
Geometry optimization made simple with translation and rotation coordinates
Authors: Wang Lee-Ping , Song Chenchen
Published: June 2016

The effective description of molecular geometry is important for theoretical studies of intermolecular interactions. Here we introduce a new translation-rotation-internal coordinate (TRIC) system which explicitly includes the collective translations and rotations of molecules, or parts of molecules such as monomers or ligands, as degrees of freedom. The translations are described as the centroid position and the orientations are represented with the exponential map parameterization of quaternions. When TRIC is incorporated into geometry optimization calculations, the performance is consistently superior to existing coordinate systems for a diverse set of systems including water clusters, organic semiconductor donor-acceptor complexes, and small proteins, all of which are characterized by nontrivial intermolecular interactions. The method also introduces a new way to scan the molecular orientations while allowing orthogonal degrees of freedom to relax. Our findings indicate that an explicit description of molecular translation and rotation is a natural way to traverse the many-dimensional potential energy surface.

The effect of an axial magnetic field Bz on an imploding metallic gas-puff Z-pinch was studied using 2D time-gated visible self-emission imaging. Experiments were performed on the IMRI-5 generator (450 kA, 450 ns). The ambient field Bz was varied from 0.15 to 1.35 T. It was found that the initial density profile of a metallic gas-puff Z-pinch can be approximated by a power law. Time-gated images showed that the magneto-Rayleigh–Taylor instabilities were suppressed during the run-in phase both without axial magnetic field and with axial magnetic field. Helical instability structures were detected during the stagnation phase for Bz < 1.1 T. For Bz = 1.35 T, the pinch plasma boundary was observed to be stable in both run-in and stagnation phases. When a magnetic field of 0.3 T was applied to the pinch, the soft x-ray energy was about twice that generated without axial magnetic field, mostly due to longer dwell time at stagnation.

Published: June 2016

We report on the combination of a state-of-the-art energy-filtering photoemission electron microscope with an intense yet compact laboratory-based gas discharge extreme ultraviolet (EUV) light source. Using a photon energy of 71.7 eV from oxygen plasma (O5+ spectral line), we demonstrate element-selective photoelectron imaging in real space and band structure mapping in reciprocal space. Additionally, the high surface sensitivity of the EUV light was used to study the surface oxidation on islands of the phase-change material Ge1Sb2Te4. The EUV light source allows the extension of spectromicroscopy, previously only feasible at synchrotron beamlines, to laboratory-based work.
