Wirtschaftlichkeitssimulation als Planungsinstrument
Authors: Geiger Manfred , Menzel Thomas 
Published: May 2017

Kurzfassung
Für die Bewertung der Wirtschaftlichkeit einer Prozesskette in der Fertigung während der Planungsphase sind das Betriebsmittelkonzept, das Produktionsprogramm und die daraus folgende Produktivität beispielsweise anhand der Fertigungskosten zu evaluieren. Komplexe dynamische Wechselwirkungen erfordern die Verwendung eines Simulationsmodells, das sich aber von den in der Produktionsplanung dominierenden ereignisorientierten Modellen unterscheidet.

Das Kennzahlensystem des Produktionssteuerungskonzepts „Perlenkette“
Authors: Weyer Matthias , Spath Dieter 
Published: May 2017

Kurzfassung
Trotz verstärkter kunden- und logistikorientierter Umgestaltung der Prozesse fehlt es an geeigneten Kennzahlensystemen. Die vorhandenen sind meist nicht in der Lage, die Prozesslandschaft transparent und damit beherrschbar zu machen. Sie konzentrieren sich vornehmlich auf herkömmliche Logistik-Kennzahlen, die sich auf direkte Kostentreiber, wie z. B. Frachten, Flächen, Bestände oder Handling, beziehen. Der vorliegende Artikel ist der zweite Teil einer Beitragsreihe, die sich mit dem Produktionssteuerungskonzept “Perlenkette” beschäftigt. Während sich der erste Aufsatz mit dem Konzept befasste, fokussiert der zweite dessen Kennzahlensystem, das mit neuen Kennzahlen die Prozesslandschaft abzubilden vermag und die verursachergerechte Ermittlung von Logistikkosten ermöglicht.
Modell einer mehrdimensionalen Outsourcing-Entscheidung
Authors: Möller Klaus 
Published: May 2017

Kurzfassung
Die zunehmende Dynamik und Schwankungsintensität auf allen Märkten haben das Risiko einer unzureichenden Auslastung der Eigenfertigungskapazität erheblich erhöht. Die zunehmende Kapitalintensität durch moderne, extrem teure Technologien hat das Risiko einer Eigenerstellung und damit die Frage nach der langfristigen Finanzierbarkeit weiter verschärft. Die zunehmende Leitungsfähigkeit der Zulieferindustrie hinsichtlich Innovation, Technik und Organisation bietet hier eine Gegenreaktion und potenzielle Problemlösung, um die Vorteile einer arbeitsteiligen Wirtschaft effizient zu nutzen.
Begriffe in der Produktionstechnik
Authors: Spur Günter 
Published: May 2017

Kurzfassung
Der Fortschritt der Technik bewirkt auch kontinuierliche Veränderungen der Fachterminologie. Das Aufkommen neuer Begriffe wird stark durch die Informationstechnik beeinflusst, die wiederum Vieles aus dem Englischen entlehnt. Außerdem erfolgt die Verbreitung des Fachschrifttums in seiner Mannigfaltigkeit immer kurzfristiger. Diese Entwicklung gibt Veranlassung zur inhaltlichen Überprüfung der einfließenden Terminologie, um das normative Bewusstsein für eindeutige Begriffsbildungen zu stimulieren. Deshalb möchte die ZWF ihrer Leserschaft Vorschläge zur Definition neuer und gebräuchlicher Begriffe der Produktionstechnik unterbreiten, die nach einem Reifungsprozess zu einem allgemeinen Begriffsverständnis führen können.

Unternehmensübergreifende Informationslogistik in der Automobilindustrie
Authors: Röder Axel , Sailer Bernd , Haasis Siegmar 
Published: May 2017

Kurzfassung
Die Koordination unternehmensübergreifender Logistiknetzwerke stellt ein wesentliches Kriterium dar, um sich von anderen Wettbewerbern zu differenzieren. Die Fokussierung der Unternehmen auf ihre individuellen Kernkompetenzen hat zu einer verstärkten Untergliederung des Wertschöpfungsprozesses geführt. Damit stehen weniger einzelne Unternehmen, sondern vermehrt ganze Wertschöpfungsketten im Wettbewerb zueinander. Eine untergliederte Wertschöpfungskette als Verbund von rechtlich und organisatorisch selbstständigen Unternehmen erschwert die informatorische Integration sowie die unternehmensübergreifende Transparenz an planungs- und steuerungsrelevanten Logistikinformationen. Durch den Wettbewerb ganzer Wertschöpfungsketten besteht die Herausforderung, ein unternehmensübergreifendes Gesamtoptimum hinsichtlich Kosten, Liefermengen und -zeiten sowie Beständen zu realisieren.

Quaternary Ammonium Gemini Surfactants Used in Enhanced Oil Recovery: Synthesis, Properties, and Flooding Experiments
Authors: Liu Zhe , Gao Ruimin , Dong Zhen , Li Xiang , Zhao Jianshe 
Published: May 2017

AbstractIn this work, quaternary ammonium gemini surfactants with different spacers and lipophilic tails were synthesized by using imidazole and halogenated hydrocarbons as raw materials. The surfactants were characterized by EA, IR, and ESI-MS. Physico-chemical properties including critical micelle concentration (CMC), surface tension at CMC (γCMC), saturated adsorption amount (Γmax), occupied area per molecule (Amin), standard free energy of micellization (ΔG0m) and adsorption (ΔG0ads), as well as the oil/water interfacial tension were completely studied. The prepared surfactants could efficiently lower the interfacial tension at water/air interfaces and oil/water interfaces. The results indicate that the ability of reducing the surface tension was affected by the surfactant arrangement, which could be further adjusted by a spacer and lipophilic tail. Accordingly, four surfactants were chosen as the representatives to evaluate the displacement efficiency in flooding experiments via using the authentic sandstone microscopic model.

Authors: Muthukkumar M. , Rajavel R. , Venkatesh G. , Vennila P. 
Published: May 2017

Abstract
Macrocyclic metal complexes viz., Co(II), Ni(II), Cu(II) and Zn(II) have been prepared using a macrocyclic Schiff base as ligand, which was derived from Isatin, 4-aminoantipyrine and o-phenylenediamine. Further, the complexes have been characterized by elemental analysis, magnetic susceptibility, molar conductance, mass spectrometry, FT-IR-, Far-IR-, UV-Vis-, EDX spectroscopy, 1H NMR and 13C NMR, ESR spectroscopy and SEM. The octahedral geometry of the complexes has been revealed by the spectral data of UV-Vis and ESR as well as by the results of the magnetic susceptibility measurements. Antimicrobial screening tests indicated that the Zn(II) metal complexes showed an excellent antimicrobial activity compared to the other studied metal complexes. The nuclease activity of the metal complexes showed that the Co(II) complex has effectively cleaved DNA. The optimized molecular structure, bond length, bond angle, dihedral angle, chemical reactivity and total energy have been evaluated using the density functional theory (DFT) with B3LYP functional level.
Synergistic Effect of Cationic Surfactants on the Rheological Behavior of Erucyl Amidosulfobetaine
Authors: Vafakish Bahareh 
Published: May 2017

Abstract
In recent times, long chain amido sulfobetaine surfactants are a very attractive subject, but their unique self assembly properties as well as the rheological behavior of the mixture of these surfactants with other surfactant types are less documented. In this paper, the rheological behavior of the erucyl amido sulfobetaine (EASB) in mixture with long chain cationic surfactants was evaluated. The results indicated that in spent acid solution, the rheological responses of erucyl amido sulfobetaine (EASB) in the presence of cationic surfactants were improved. The effect of surfactants concentration and temperature were also studied.

Published: May 2017

Background: Neurorehabilitation requires the development of severity-dependent and successful therapies for arm/hand rehabilitation in stroke patients. Objective: To evaluate the effectiveness of adding mirror therapy to bilateral EMG-triggered multi-channel electrostimulation for the treatment of severe arm/hand paresis in stroke patients. Methods: The subjects of this randomized, controlled, multicentre study were stroke patients who had suffered their first insult between 1 and 6 months before study start and had severe or very severe arm/hand paresis, as classified by Fugl-Meyer-Assessment. Subjects were randomly allocated to an intervention group ( n = 16) or control group ( n = 17). Both groups were treated for 3 weeks (5x week, 30 minutes) with bilateral EMG-triggered multi-channel electrostimulation. The intervention group additionally received mirror feedback of the unaffected limb. The primary outcome measure was motor recovery of the upper extremities, as measured by the Fugl-Meyer Assessment. Results: The Intervention Group with very severe paresis had significantly better motor recovery in total Fugl-Meyer Assessment ( p = 0.017) at a medium effect size (Cohen) of d = 0.7, due to a significant recovery of shoulder and elbow function ( p = 0.003) in the Fugl-Meyer Assessment Part A subtest. For subjects with severe paresis, additional mirror therapy did not significantly influence outcome. Conclusion: Additional mirror therapy in combination with EMG-triggered multi-channel electrostimulation is therapeutically beneficial for post-acute stroke patients with very severe arm/hand paresis.
Overlapping community detection and temporal analysis on Q&A sites
Authors: Meng Zide , Gandon Fabien , Faron Zucker Catherine 
Published: May 2017

In many social networks, people interact based on their relationship network. Community detection algorithms are then useful to reveal the sub-structures of a network. Identifying these users’ communities can help us assist their life-cycle. However, in certain kinds of online communities such as question-and-answer (Q&A) sites or forums, people interact based on common topics of interest, rather than an explicit relationship network. Therefore, many traditional community detection techniques do not apply directly. Discovering those topics of interest is critical to identify users’ communities. Besides, users’ activities on certain topics of interest are evolving with time and it is therefore very important to extract their temporal dynamics. In this paper, we first propose Topic Trees Distributions (TTD), an efficient approach for extracting topics from Q&A sites in order to detect overlapping communities. We then extend TTD to propose Temporal Topic Expertise Activity (TTEA), a graphical probabilistic model to extract both topics-based expertise and temporal information. We evaluated and compared our models with state-of-the-art approaches on a dataset extracted from the popular Q&A site StackOverflow.
Ownership and Obligation: Restitution, Vindication and the Recovery of Moveables in Stair'sInstitutions
Authors: Holligan Bonnie 
Published: May 2017

To what extent does Scots law recognise an action for recovery of moveable property based on the ownership of the pursuer? Doctrinal answers to this question are usually forced to engage with the assertion of Lord Stair that “we make not use of the name or nature of Vindication”. This article seeks to further historical and doctrinal understanding of Stair's views by locating them within the broader theological and philosophical context of the development in Europe of a Reformed theory of subjective rights.It is argued that Stair's comments must be understood in the context of disagreement about the role and status of Roman law in Scotland, and also a morally and philosophically rich understanding of ownership which focussed on the creation of a sphere of individually protected rights rather than the strictures of the Roman distinction between property and obligation. The article highlights debate between Stair and one of the other prominent jurists of the period, Sir George Mackenzie, and the extent to which their conflicting accounts of property law doctrine are inseparable from questions about legal authority and national identity. By situating Stair's views within their historical and intellectual context, it is hoped to encourage a more reflective approach to their status as doctrinal authority.
Absolute Magnitudes of Seismic Red Clumps in the Kepler Field and SAGA: The Age Dependency of the Distance Scale

Published: May 2017

Abstract
Red clump stars are fundamental distance indicators in astrophysics, although theoretical stellar models predict a dependence of absolute magnitudes with age. This effect is particularly strong below ∼2 Gyr, but even above this limit a mild age dependence is still expected. We use seismically identified red clump stars in the Kepler field for which we have reliable distances, masses, and ages from the SAGA survey, to first explore this effect. By excluding red clump stars with masses larger than

(corresponding to ages younger than 2 Gyr), we derive robust calibrations linking intrinsic colors to absolute magnitudes in the following photometric systems: Strömgren by, Johnson BV, Sloan griz, 2MASS JHK

s
, and WISE

. With the precision achieved we also detect a slope of absolute magnitudes

in the infrared, implying that distance calibrations of clump stars can be off by up to

in the infrared (over the range from 2 to 12 Gyr) if their ages are unknown. Even larger uncertainties affect optical bands, because of the stronger interdependency of absolute magnitudes on colors and age. Our distance calibrations are ultimately based on asteroseismology, and we show how the distance scale can be used to test the accuracy of seismic scaling relations. Within the uncertainties our calibrations are in agreement with those built upon local red clumps with Hipparcos parallaxes, although we find a tension, which, if confirmed, would imply that scaling relations overestimate the radii of red clump stars by 2 ± 2%. Data releases post Gaia DR1 will provide an important testbed for our results.
Multi-spacecraft Observations of the Coronal and Interplanetary Evolution of a Solar Eruption Associated with Two Active Regions
Authors: Hu Huidong , Liu Ying D. , Wang Rui , Zhao Xiaowei , Zhu Bei , Yang Zhongwei 
Published: May 2017

Abstract
We investigate the coronal and interplanetary evolution of a coronal mass ejection (CME) launched on 2010 September 4 from a source region linking two active regions (ARs), 11101 and 11103, using extreme ultraviolet imaging, magnetogram, white-light, and in situ observations from SDO, STEREO, SOHO, VEX, and Wind. A potential-field source-surface model is employed to examine the configuration of the coronal magnetic field surrounding the source region. The graduated cylindrical shell model and a triangulation method are applied to determine the kinematics of the CME in the corona and interplanetary space. From the remote sensing and in situ observations, we obtain some key results: (1) the CME was deflected in both the eastward and southward directions in the low corona by the magnetic pressure from the two ARs, and possibly interacted with another ejection, which caused that the CME arrived at VEX that was longitudinally distant from the source region; (2) although VEX was closer to the Sun, the observed and derived CME arrival times at VEX are not earlier than those at Wind, which suggests the importance of determining both the frontal shape and propagation direction of the CME in interplanetary space; and (3) the ICME was compressed in the radial direction while the longitudinal transverse size was extended.
Multiwavelength Polarization of Rotation-powered Pulsars
Authors: Harding Alice K. , Kalapotharakos Constantinos 
Published: May 2017

Abstract
Polarization measurements provide strong constraints on models for emission from rotation-powered pulsars. We present multiwavelength polarization predictions showing that measurements over a range of frequencies can be particularly important for constraining the emission location, radiation mechanisms, and system geometry. The results assume a generic model for emission from the outer magnetosphere and current sheet in which optical to hard X-ray emission is produced by synchrotron radiation (SR) from electron–positron pairs and γ-ray emission is produced by curvature radiation (CR) or SR from accelerating primary electrons. The magnetic field structure of a force-free magnetosphere is assumed and the phase-resolved and phase-averaged polarization is calculated in the frame of an inertial observer. We find that large position angle (PA) swings and deep depolarization dips occur during the light-curve peaks in all energy bands. For synchrotron emission, the polarization characteristics are strongly dependent on photon emission radius with larger, nearly 180°, PA swings for emission outside the light cylinder (LC) as the line of sight crosses the current sheet. The phase-averaged polarization degree for SR is less that 10% and around 20% for emission starting inside and outside the LC, respectively, while the polarization degree for CR is much larger, up to 40%–60%. Observing a sharp increase in polarization degree and a change in PA at the transition between X-ray and γ-ray spectral components would indicate that CR is the γ-ray emission mechanism.
Systematic Analysis of Spectral Energy Distributions and the Dust Opacity Indices for Class 0 Young Stellar Objects
Authors: I-Hsiu Li Jennifer , Baobab Liu Hauyu , Hasegawa Yasuhiro , Hirano Naomi 
Published: May 2017

Abstract
We are motivated by the recent measurements of dust opacity indices (β) around young stellar objects (YSOs), which suggest that efficient grain growth may have occurred earlier than the Class I stage. The present work makes use of abundant archival interferometric observations at submillimeter, millimeter, and centimeter wavelength bands to examine grain growth signatures in the dense inner regions (<1000 au) of nine Class 0 YSOs. A systematic data analysis is performed to derive dust temperatures, optical depths, and dust opacity indices based on single-component modified blackbody fittings to the spectral energy distributions (SEDs). The fitted dust opacity indices (β) are in a wide range of 0.3–2.0 when single-component SED fitting is adopted. Four out of the nine observed sources show β lower than 1.7, the typical value of the interstellar dust. Low dust opacity index (or spectral index) values may be explained by the effect of dust grain growth, which makes

. Alternatively, the very small observed values of β may be interpreted by the presence of deeply embedded and hot inner disks, which only significantly contribute to the observed fluxes at long wavelength bands. This possibility can be tested by the higher angular resolution imaging observations of ALMA or more detailed sampling of SEDs in the millimeter and centimeter bands. The β values of the remaining five sources are close to or consistent with 1.7, indicating that grain growth would start to significantly reduce the values of β no earlier than the late Class 0 stage for these YSOs.
Regeneration of Defective Epithelial Basement Membrane and Restoration of Corneal Transparency After Photorefractive Keratectomy
Authors: Marino Gustavo K. , Santhiago Marcony R. , Santhanam Abirami , Torricelli Andre A. M. , Wilson Steven E. 
Published: May 2017

PURPOSE:
To study regeneration of the normal ultrastructure of the epithelial basement membrane (EBM) in rabbit corneas that had −9.00 D photorefractive keratectomy (PRK) and developed late haze (fibrosis) with restoration of transparency over 1 to 4 months after surgery and in corneas that had incisional wounds.

METHODS:
Twenty-four rabbits had one of their eyes included in one of the two procedure groups (−9.00 D PRK or nearly full-thickness incisional wounds), whereas the opposite eyes served as the unwounded control group. All corneas were evaluated with slit-lamp photographs, transmission electron microscopy, and immunohistochemistry for the myofibroblast marker alpha-smooth muscle actin and collagen type III.

RESULTS:
In the −9.00 D PRK group, corneas at 1 month after surgery had dense corneal haze and no evidence of regenerated EBM ultrastructure. However, by 2 months after surgery small areas of stromal clearing began to appear within the confluent opacity (lacunae), and these corresponded to small islands of normally regenerated EBM detected within a larger area of the excimer laser-ablated zone with no evidence of normal EBM. By 4 months after surgery, the EBM was fully regenerated and the corneal transparency was completely restored in the ablated zone. In the incisional wound group, the two dense, linear corneal opacities were observed at 1 month after surgery and progressively faded by 2 and 3 months after surgery. The EBM ultrastructure was fully regenerated at the site of the incisions, including around epithelial plugs that extended into the stroma, by 1 month after surgery in all eyes.

CONCLUSIONS:
In the rabbit model, spontaneous resolution of corneal fibrosis (haze) after high correction PRK is triggered by regeneration of EBM with normal ultrastructure in the excimer laser-ablated zone. Conversely, incisional wounds heal in rabbit corneas without the development of myofibroblasts because the EBM regenerates normally by 1 month after surgery.
