Published: March 2017

AbstractThree dimensional (3D) HfO2‐ZnO heteroarchitecture comprised of thin coating of HfO2 on self assembled 3D ZnO urchins with pointed apex has been synthesized using hydrothermal route followed by Pulsed Laser Deposition (PLD). The as‐synthesized HfO2‐ZnO heteroarchitecture was characterized using XRD, SEM, EDS, and (HR) TEM, in order to reveal its structural, morphological, and chemical properties. The HfO2‐ZnO heteroarchitecture emitter exhibits superior field emission (FE) behaviour in contrast to the pristine ZnO urchins, demonstrated by delivery of high emission current density of ∼ 885 μA/cm2 at an applied field of ∼ 3.35 V/μm, against ∼383 μA/cm2 at an applied field of ∼ 4.32 V/μm for the pristine ZnO urchins emitter. Interestingly, the HfO2‐ZnO heteroarchitecture emitter exhibits excellent emission current stability characterized with fewer fluctuations, owing to very good ion‐bombardment resistance offered by the HfO2 coating. Furthermore, the heteroarchitecture thus obtained facilitates tailoring of the morphology with high aspect ratio and modulation of electronic properties as well, thereby enhancing the FE behaviour.Despite HfO2 being wide band gap and high‐k material, the HfO2‐ZnO heteroarchitecture exhibits potential as promising candidate for fabrication of high current density cold cathode

AbstractA new amide based extractants namely N,N‐Dihexyl‐2‐ethylhexanamide (DH2EHA) has been synthesized and characterized for extraction of uranium. The formation of UO2(NO3)3.2DH2EHA complex in the organic phase was established by X‐ray diffraction. The X‐ray structure was further corroborated by the density functional theoretical calculation. Furthermore, DFT approach was adopted to explain the relative stability of uranium and rare earth complex with DH2EHA by determining the free energy of extraction. The calculated selectivity trend from free energy of extraction using 1:2 stoichiometry for Nd and Yb was found to be Yb3+>UO22+>Nd3+ which does not follow the experimental trend of UO22+>Nd3+>Yb3+. But, the correct selectivity order is recovered after consideration of 1:3 stoichiometry for Nd and Yb. Thus, the correct selectivity order was understood from a combined experimental and density functional theoretical studies.
Zur Grundinstandsetzung der Köhlbrandbrücke
Authors: Brux Gunther 
Published: March 2017

AbstractSeit über 40 Jahren verbindet die Köhlbrandbrücke im ehemaligen Freihafen des Hamburger Hafens die Elbinsel Wilhelmsburg mit der Autobahn A7. Die Brückenkonstruktion nach einem Entwurf des Bauingenieurs Paul Boué und des Architekten Egon Jux überspannt einen 325 m breiten Arm der Südelbe, den sogenannten Köhlbrand. Dank ihrer 135 m hohen Pylone ist die Köhlbrandbrücke schon von Weitem sichtbar und gilt nach den 1970er Jahren als eines der Wahrzeichen der Hansestadt Hamburg. Mit 3 618 m ist die Brücke die zweitlängste Straßenbrücke Deutschlands (Bild 1).Das Gesamtbauwerk umfasst zwei Rampenbrücken aus Spannbeton sowie die 520 m lange Strombrücke, die als Schrägseilbrücke in Stahl ausgeführt ist. 88 Stahlseile sind fächerförmig am äußeren Brückenkasten sowie an den Pylonen befestigt. Der Brückenträger besteht aus einem Stahlhohlkasten mit einer rund 17 m breiten Fahrbahnplatte.
Die Digitalisierung im Bauwesen ist eine Chance

AbstractDurch die Digitalisierung verändern sich unser Leben, unsere Gesellschaft und ganze Wirtschaftszweige. Sogenannte Disruptoren wie Apple, Google, Uber und viele andere führen in kürzester Zeit zu einer Neuordnung einer Branche. Beispiele für disruptive Technologien sind unter anderem die Digitalkamera, das Smartphone, das Elektroauto und eben auch das CAD (Computer Aided Design), das in den 90er Jahren die technische Handzeichnung mit Tuschestift und Zeichenbrett innerhalb kürzester Zeit ersetzte (Bild 1).Digitaler Prozesswandel, das parametrische Entwerfen und der Einsatz von BIM als Planungsmethode führen vermehrt auch im Bauwesen zu grundlegenden Veränderungen in den Planungsprozessen und Planungsschnittstellen. Sie ermöglichen die Planung, Berechnung und Umsetzung deutlich komplexerer Bauwerke, führen zu durchgängigen Prozessketten zwischen Planung, Ausführung und Nutzung, und ermöglichen die koordinierte Bündelung aller Bauwerksinformationen in einer Projektdatenbank. Durch die Veränderung unserer Prozesse hin zu einer teamorientierten Planungsmethode lassen sich Paradigmen aufbrechen und Fehlentwicklungen korrigieren. „Aber dafür müssen wir heraus aus der Deckung, selbst ausprobieren und mit reden [1]”.
Concurrency-preserving and sound monitoring of multi-threaded component-based systems: theory, algorithms, implementation, and evaluation

Published: March 2017

Abstract
This paper addresses the monitoring of logic-independent linear-time user-provided properties in multi-threaded component-based systems. We consider intrinsically independent components that can be executed concurrently with a centralized coordination for multiparty interactions. In this context, the problem that arises is that a global state of the system is not available to the monitor. A naive solution to this problem would be to plug in a monitor which would force the system to synchronize in order to obtain the sequence of global states at runtime. Such a solution would defeat the whole purpose of having concurrent components. Instead, we reconstruct on-the-fly the global states by accumulating the partial states traversed by the system at runtime. We define transformations of components that preserve their semantics and concurrency and, at the same time, allow to monitor global-state properties. Moreover, we present RVMT-BIP, a prototype tool implementing the transformations for monitoring multi-threaded systems described in the Behavior, Interaction, Priority (BIP) framework, an expressive framework for the formal construction of heterogeneous systems. Our experiments on several multi-threaded BIP systems show that RVMT-BIP induces a cheap runtime overhead.

Published: March 2017

AbstractObjectivesCritical limb ischemia (CLI) is a clinical diagnosis, confirmed by objective tests, usually ankle‐brachial index (ABI), toe pressure (TP) and TcPO2. Furthermore, the anatomical lesions in patients affected by CLI were visualized by ultrasound, angiography, CTA, or MRA. Indocyanine green fluorescence imaging (ICG‐FI) is a diagnostic modality for assessing foot perfusion. We aimed to study the usefulness of ICG‐FI in the quality control of revascularization.Materials and methodsOne hundred and four CLI limbs in 101 patients were studied with ICG‐FI using SPY Elite before and after open or endovascular revascularization. ABI and TP were also measured. After ICG‐FI, assessment of circulation was done using time–intensity curve derived from the two regions of interest the one being in the plantar side of the foot and the other in the dorsal side of the foot. Three parameters were derived from the curves: maximum intensity (the absolute value of the maximum intensity); intensity rate (the value from the time–intensity curve describing the increase in maximum intensity/s) and SPY10 (the intensity achieved during the first 10 s after the foot starts to gain intensity).ResultsSixty‐two limbs presented category 3 of Rutherford classification, 12 limbs category 4, and 30 limbs category 5. Ninety‐five technically successful procedures were achieved, 63 (66.3%) endovascular and 32 (33.7%) surgical revascularizations. In 9 (9.5%) patients, an in‐line flow from the aorta to the foot was not achieved due to a failure to recanalize the occlusion (n = 7) or due to distal embolization (n = 2). ABI was not reliable in 58 patients (57.4%) mostly due to pseudohypertension and TPs in 49 (48.5%) patients mostly due to previous minor amputations. ICG‐FI was successful in all patients. The mean intensity values before and after the procedure in patients who underwent successful revascularization were 81 ± 47 units and 120 ± 5 units of intensity (p <. 001) and intensity rates 4.2 ± 4 and 8.0 ± 6.2 units/s (p =. 001), respectively. In the PTA patients in whom the revascularization was unsuccessful, no changes were seen in the hemodynamic parameters. In 6 (8.8%) patients who underwent technically successful revascularization, the SPY values were worse after the revascularization than at the baseline.ConclusionsICG‐FI with SPY Elite provides reliable information on the increase in perfusion after revascularization, in addition to implicating possible failure if there is no improvement in the ICG‐FI variables. Unlike ABI and TP, it can be performed in all patients. It gives valuable information to complement traditional assessment methods.

Published: March 2017

AbstractBackgroundPharyngoesophageal stricture (PES) is an Achilles’ heel in the management of corrosive injury. Advances in endoscopic techniques were utilized in its management. We classified the stricture as per its dilatability and then planned their treatment.MethodsPES was sub‐categorized based on endoscopic dilatation and availability of cervical oesophagus: group‐1 stricture with available cervical oesophagus; group‐2 stricture with some part of upper oesophagus made available after endoscopic dilatation and anastomosis in cervico‐pharyngeal area; group‐3 stricture not amenable for dilatation, anastomosis done at the pharynx. Endoscopic dilatation was performed using through‐the‐scope pyloric balloon. Number and duration of dilatation sessions before surgery, incidence of tracheostomy, time and incidence for re‐stricture and present status of swallowing were evaluated.ResultsOf 226 patients managed, 46 underwent oesophageal replacement for PES. Group 1, 2 and 3 had 12, 14 and 20 patients, respectively. An average 3 (2–4) preoperative balloon dilatation sessions were performed over 6–8 weeks. Tracheostomy was required in 1, 0, 8 patients (p = 0.010), and median hospital stay was 10, 9 and 13 days (p = 0.09) in group 1, 2, 3, respectively. Re‐stricture developed in 4/12, 4/14, 9/20 patients with average sessions of dilatation required in post‐operative period was 4, 3.5 and 8 in group 1, 2, 3, respectively. >90% of patients are taking normal diet in each group.ConclusionWe attempted to avoid the high anastomosis by dilating the PES and step down the level of anastomosis in two‐third patients. We thereby avoided tracheostomy, aspiration and swallowing problems related to high strictures.

Published: March 2017

AbstractOutcome measurement in clinical genetics is challenging. Robust outcome measures are needed to provide evidence to support service development within genetic counseling. The Genetic Counselling Outcome Scale (GCOS‐24), a Patient Reported Outcome Measure (PROM), was developed in English and validated with clinical genetics patients in the British NHS. This study reports the translation and adaptation of the GCOS‐24 for use in Denmark. GCOS‐24 was translated and back translated, supervised by an expert committee. Feedback on the first version was collected from genetic counseling patients in qualitative interviews focusing on instructions for use, response options and specific items considered semantically difficult. After further adjustment the adapted and translated version was administered to a second sample of patients, with responses analyzed using descriptive statistics. Eighteen interviews were conducted, and led to adjustment of item wording. Sixty‐one patients completed the final version GCOS‐24dk. Internal consistency is good (Cronbach's α =0.79), with an acceptable number of missing responses and no floor or ceiling effect observed. GCOS‐24 has been successfully translated and adapted for use in a Danish setting. The study confirms the feasibility of local adaptation of patient reported outcome measures and stresses the importance of adaptation, even across quite similar populations and health care systems.
Evaluation of Cavitation Erosion Behavior of Commercial Steel Grades Used in the Design of Fluid Machinery
Authors: Tzanakis I. , Bolzoni L. , Eskin D. G. , Hadfield M. 
Published: March 2017

Abstract
The erosion response under cavitation of different steel grades was assessed by studying the erosion rate, the volume removal, the roughness evolution, and the accumulated strain energy. A 20 kHz ultrasonic transducer with a probe diameter of 5 mm and peak-to-peak amplitude of 50 μm was deployed in distilled water to induce damage on the surface of commercial chromium and carbon steel samples. After a relatively short incubation period, cavitation induced the formation of pits, cracks, and craters whose features strongly depended on the hardness and composition of the tested steel. AISI 52100 chromium steel showed the best performance and is, therefore, a promising design candidate for replacing the existing fluid machinery materials that operate within potential cavitating environments.

Published: March 2017

AbstractRehabilitation traumatology has developed within the field of physical medicine and rehabilitation as a specialized area of knowledge in which the physiatrist works with the traumatology team to enhance the functional outcome of trauma patients. Based on the definition of traumatology in the American Heritage Dictionary, the authors propose rehabilitation traumatology be “the branch of medicine that deals with the treatment of serious wounds, injuries, and disabilities,” “to restore [the patient] to good health or useful life.” This article reviews the history of traumatology, special considerations of the traumatology patient through the continuum of care, and concepts toward the creation of a rehabilitation traumatology program.Level of EvidenceV
Gradient theory of phase transitions with boundary contact energy
Authors: Modica Luciano 
Published: March 2017

We study the asymptotic behavior as

ε → 0^+

of solutions of the variational problems for the Van der Waals–Cahn–Hilliard theory of phase transitions in a fluid. We assume that the internal free energy, per unit volume, is given by

ε^2|∇ρ|^2 + W(ρ)

and the contact energy with the container walls, per unit surface area, is given by

εσ(ρ)

, where

ρ

is the density. The result is that such solutions approximate a two-phases configuration satisfying a variational principle related to the equilibrium configuration of liquid drops.

Nonlinear Evolution Equations and Analyticity. I
Authors: Kato Tosio , Masuda Kyûya 
Published: March 2017

We prove a theorem on abstract nonlinear evolution equations

∂_tu = F(t, u)

in a Banach space, which aims at estimating certain families of Liapunov functions for the solutions. The theorem is useful in proving global analyticity (in space variables) of solutions of various partial differential equations, such as the equations of Korteweg–de Vries, Benjamin–Ono, Euler, Navier–Stokes, nonlinear Schrödinger, etc. In this paper it is shown that if the initial state of the KdV or the BO equation has an analytic continuation that is analytic and

L^2

in a strip containing the real axis, then the solution (which is unique in

H^2(ℝ)

) has the same property for all time, though the width of the strip might decrease with time.

On montre en particulier que si la condition initiale de l’équation de Korteweg–de Vries ou de Benjamin–Ono a un prolongement analytique

Sexual Violence in the Eritrean National Service
Authors: Kibreab Gaim 
Published: March 2017

Abstract:Claims of sexual violence against female conscripts by military commanders abound in the Eritrean National Service (ENS), but hitherto there has been no attempt to subject these claims to rigorous empirical scrutiny. This article is a partial attempt to fill the gap. Based on data collected through snowball sampling from 190 former conscripts in the United Kingdom, Switzerland, Norway, South Africa, Kenya, and Sweden who fled from the ENS, supplemented by data from systematically selected key informants who were interviewed in depth, it examines the extent to which female conscripts serving in the ENS were subjected to sexual violence and harassment by their commanders, including at the Sawa military training camp. The extensive data, based on the perceptions and experiences of respondents who served on average about six years, suggest that sexual abuse is rampant throughout the ENS, particularly among female conscripts who are assigned to work at the camp subsequent to the six months of military training.
Comprehending Sociality: Hegel Beyond his Appropriation in Contemporary Philosophy of Recognition
Authors: Krijnen Christian 
Published: March 2017

AbstractContemporary philosophy of recognition represents probably the most prominent direction that presently claims to introduce an updated version of classical German idealism into ongoing debates, including the debate on the nature of sociality. In particular, studies of Axel Honneth offer triggering contributions in Frankfurt School fashion while at the same time rejuvenating Hegel’s philosophy in terms of a philosophy of recognition. According to Honneth, this attempt at a rejuvenation also involves substantial modification of Hegelian doctrines. It is shown that Honneth underestimates the implications of Hegel’s thoughts about the theme, method and systematic form of philosophy. As a consequence, Honneth’s social philosophy is, on the one hand, in need of a plausible foundation. This leads, on the other hand, to a different construction of the social within philosophy than Honneth offers.
A within-country study of leadership perceptions and outcomes across native and immigrant employees: Questioning the universality of transformational leadership
Authors: Holten Ann-Louise , Bøllingtoft Anne , Carneiro Isabella Gomes , Borg Vilhelm 
Published: March 2017

AbstractThis study investigates the universality of transformational leadership with respect to employee perceptions and three outcomes: job satisfaction, self-rated health, and well-being. We do so among employees of different national and cultural backgrounds, yet within a shared national and sectorial setting. Our study has a repeated measures design based on survey data from 2,947 employees (2,836 natives Danes and 111 immigrants) in the Danish elder care sector. While we find no difference between native Danes and immigrants in their perception of transformational leadership, we find that transformational leadership is not a universal predictor of outcomes. Although transformational leadership predicts change in none of the outcomes for immigrants, it does predict change in job satisfaction and well-being for native Danes. Based on our findings, we suggest applying a combination of universalistic and contingency paradigms when leading composite employee groups.
