Published: April 2017

Background: Ankle fracture surgeries are generally safe and effective procedures; however, as quality-based reimbursement models are increasingly affected by postoperative readmission, we aimed to determine the causes and risk factors for readmission following ankle fracture surgery. Methods: Ankle fracture cases were identified from the prospectively collected American College of Surgeons National Surgical Quality Improvement Program from 2013 to 2014. Demographics, comorbidities, and fracture characteristics were collected. Rates of 30-day adverse events and readmissions were determined as well as the causes for readmission. Multivariable logistic regression analyses were performed to identify risk factors associated with having any adverse events and being readmitted within 30 days of surgery. Results: There were 5056 patients included; 167 (3.3%) were open fractures. The rate of any postoperative adverse event was 5.2%. There were 116 unplanned readmissions, with a readmission rate of 2.3%. Of the 116 unplanned readmissions, 49 (42.2%) were for reasons related to the surgery or surgical site, with the most common causes being deep surgical site/hardware infections (12.9%), superficial site infections (11.2%), and wound disruption (6.9%). Most readmissions were for reasons unrelated to the surgical site (51.7%), including cardiac disorders (8.6%), pulmonary disorders (7.8%), and neurological/psychiatric disorders (6.9%). The cause of readmission was unknown for 6% of readmissions. With multivariable logistic regression, the strongest risk factors for readmission were a history of pulmonary disease (odds ratio [OR], 2.29), American Society of Anesthesiologists (ASA) class ≥3 (OR, 2.28), and open fractures (OR, 2.04) (all P < .05). Conclusion: In this cohort of 5056 ankle fracture cases, 2.3% of patients were readmitted within 30 days, with at least 51.7% of all unplanned readmissions due to causes unrelated to the surgery or surgical site. Predictors of readmission included a history of pulmonary disease, higher ASA class, and open fractures. Based on these findings, we advocate close medical follow-up with nonorthopaedic providers after discharge for high-risk patients. Level of Evidence: Level III.
Ethnological Hermeneutics for an Early Colonial Encounter on the Island of San Juan: The 1532Probanzaof Juan González
Authors: De La Luz-Rodríguez Gabriel 
Published: April 2017

AbstractThis article argues for the importance of an ethnological hermeneutics in the study of the early colonial period in the Caribbean. It does so by applying this methodology to a founding document concerning early colonial encounters on the island of San Juan or present-day Puerto Rico. The 1532 probanza of Juan González is privileged as a text through which crucial information concerning the Spanish colonization of San Juan and its original inhabitants could be obtained. The article thus contextualizes the probanza as part of a genre of colonial writing within the amply known relaciones de méritos y servicios.
Paraplegia after sclerotherapy of varicose leg veins
Authors: Brenner E. , Prinz N. , Glowacki P. , Moersdorf M. , Maschke M. , Frings N. 
Published: April 2017

SummaryWe would like to present the case of paraplegia due to venous spinal ischaemia, which occurred after sclerotherapy of leg veins and subsequent to previous venous surgery. After exclusion of other pathogenetic causes such as surgery, tumescent local anaesthesia or neurological, infections, cardiological and haemosteaseological causes, this complication must be regarded as a consequence of sclerotherapy. Sources in literature describe shunts (shortened connections) between the leg veins and the venous spinal system, thus enabling minutest particles from sclerotherapy to enter the veins and possibly have a cytotoxic or microembolic effect with spinal ischaemia.
Evaluation of hearing level in patients on long term aspirin therapy
Authors: Pokharel Apar , Bhandary Sangita 
Published: April 2017

Introduction: Aspirin is a routinely prescribed drug, most notably for cardiovascular diseases, such as myocardial ischemia. This cross sectional, comparative study study aims to explore differences in hearing status between the cardiovascular disease patients on aspirin therapy and age matched healthy controls.Methods: The study population consisted of 182 patients with heart disease taking long term aspirin (i.e., for more than one year). The control population consisted of 221 age matched healthy controls who were not taking aspirin.Results: Not aspirin, but the age of the patient was found to be the important risk factor for hearing loss. Conclusions: When confounding factors like age of the patient, hypertension and diabetes were taken into account, aspirin in its antiplatelet dose was not found to be the cause of any audiological problems like tinnitus and hearing loss.

Authors: Mahoney-Davies Gerwyn , Davis Cara , Glen Catriona , Clifton Catherine , Salkovskis Paul M 
Published: April 2017

Aims and objectives: The aims of this study were to understand the emotional and psychological experiences of patients with heart failure in a busy NHS service and make recommendations for how best to support this population. Background: People with heart failure often experience depression, anxiety and other emotional and psychological difficulties. Their quality of life is reduced. Qualitative studies attempting to understand this have reported conflicting findings. Design: A qualitative approach was taken, with some supporting quantitative data. Methods: Ten participants were asked to complete the PHQ–9 and GAD–7, and rate their level of concern about their mood, anxiety, quality of life and social functioning. They completed a semi-structured interview about their experience of living with heart failure and the emotional and psychological impact of this. The interview was analysed thematically. Results: Participants scored in the moderate range on both depression and anxiety measures. They were more concerned about their mood, anxiety, quality of life and social functioning now than before the onset of heart failure. The themes present in the interview data were: changes to self and others; emotional reactions; thoughts about death; expectations for the future; and hospital experiences. Conclusions: Some people with heart failure report moderate levels of depression and anxiety, and significant changes in their lives; they display varying emotional reactions to these. People have clear expectations for the future and impose limits on their life. Services can make changes to support this population. Suggestions for doing this are made.
Crude Kaolin Dissolution in the Absence and Presence of Sodium Poly(Acrylic Acid), Sodium Hexametaphosphate, and Sodium Silicate under Different Experimental Conditions
Authors: Demir Feridun 
Published: April 2017

AbstractThe influence of anionic dispersing agents, such as sodium poly(acrylic acid), sodium hexametaphosphate, and sodium silicate on the dissolution of crude kaolin was examined by measuring the dissolved metals produced in the absence and presence of dispersing agents. For this purpose, the rheological and structural changes caused by the dissolution of kaolin metal constituents were studied in batch mode using several parameters, namely, solids (wt.%), pH, contact time (aging), and dispersing agent dose. A noteworthy increase in kaolin dissolution was caused by the presence of dispersing agents, particularly poly(acrylic acid) and sodium hexametaphosphate. These agents produced conspicuously large amounts of dissolved Al in comparison to the other experimental treatments. Little dissolved Si was measured under similar conditions in distilled water, but the amount of Si released using dispersing agents was nearly double that observed in distilled water only. Excess dispersing agents interacted with kaolin and dissolved accessory elements in the kaolin (i.e. Fe, Ca, Mg) and thus released enough Fe to form a stable Fe—dispersant complex. The present study showed that this phenomenon also contributed to a significant increase in the release of dissolved Al and Si through complexation.

Published: April 2017

Abstract
The paper presents example tests of the functional quality of selected designs of dental bridges. These were: porcelain bridges on a metal base (cobalt based alloy), porcelain bridges on a zirconia base (zirconia ceramic – Zirkon Zahn), and full zirconia bridges (Zirkon Zahn). For the purpose of the study, durability of bridges in cyclic fatigue testing was adopted as a measure of their quality. The tests were carried out on a Zwick Roell Z010 universal testing machine. They consisted in cyclic loading and unloading of dental bridges mounted on gypsum models at a loading force of F= 400 [N] and a frequency of load of f= 1 [Hz]. Each bridge was subjected to a cycle of 7200 loads. The results show that there are no significant differences in the functional quality of the bridges.
The characteristic of deformability and quantitative description of the microstructure of hot-deformed Ni-Fe superalloy
Authors: Ducki K. J. , Rodak K. , Mendala J. , Wojtynek L. 
Published: April 2017

Abstract
The paper presents the results of research concerning the influence of hot plastic working parameters on the deformability and microstructure of a Ni-Fe superalloy. The research was performed on a torsion plastometer in the range of temperatures of 900-1150°C, at a strain rates 0.1 and 1.0 s-1. Plastic properties of the alloy were characterized by the worked out flow curves and the temperature relationships of flow stress and strain limit. The structural inspections were performed on microsections taken from plastometric samples after so-called “freezing”. The stereological parameters as the recrystallized grain size, inhomogenity and grain shape have been determined. Functional relations between the Zener-Hollomon parameter and the maximum yield stress and the average grain area have been developed and the activation energy for hot working has been estimated.
ICT Capacity Building: A Critical Discourse Analysis of Rwandan Policies from Higher Education Perspective

Published: April 2017

Abstract
With the development of technology in the 21st Century, education systems attempt to integrate technology-based tools to improve experiences in pedagogy and administration. It is becoming increasingly prominent to build human and ICT infrastructure capacities at universities from policy to implementation level. Using a critical discourse analysis, this study investigates the articulation of ICT capacity building strategies from both national and institutional ICT policies in Rwanda, focusing on the higher education. Eleven policy documents were collected and deeply analyzed to understand which claims of ICT capacity building are made. The analysis shows that strategies for building ICT capacities are evidently observed from national level policies and only in two institutional policies (KIST and NUR). Among 25 components of ICT capacity building used, the ones related to human capacity are not plainly described. Additionally, neither national nor institutional policy documents include the creation of financial schemes for students to acquire ICT tools whilst learners are key stakeholders. Although there is some translation of ICT capacity building strategies from national to some institutional policies, planning for motivation and provision of incentives to innovators is not stated in any of the institutional policies and this is a key to effective technology integration.
Research on Particles’ Velocity Distribution in a Whirlpool Separator Using the PIV Method of Measurement
Authors: Sterczyńska Monika , Jakubowski Marek 
Published: April 2017

Abstract
The cylindrical whirlpool is used to separate hot trub from beer wort. When the tank is being filled and the contained mixture is swirled, a phenomenon takes place the main principle of which is formation of a cone of residue in the center of the tank. This paper is aimed at further development of the research on symmetrization of the cone-accumulating flow during tank filling. Herein are presented average values of particles’ velocity while in rotational motion in a whirlpool tank of modified structure. The modification is a vertically reduced baffle attached to the tank’s bottom. The experiments were conducted for two different filling rates and three different baffle positions. Measurements of particles’ velocity were performed with the PIV method. Results have been presented in the form of surface of average particles’ velocity distribution for given radius values throughout the entire process. The most advantageous baffle positions were determined.
Conditioning reduces kernel damage when impact shelling almonds
Authors: Shirmohammadi Maryam , Fielke John 
Published: April 2017

Abstract
Almonds can be classified based on their shell characteristics from soft to hard shell varieties. The majority of Australian and Californian varieties have soft shell properties. Most Spanish almond varieties have hard shells. Although having a hard sealed shell protects the kernel from insect damage it affects their processability. Common commercial almond processing equipment simultaneously compresses and shears the almonds and this creates a high percentage of damaged kernels from the broken shell being forced into the kernel, particularly for hard shell varieties. This paper shows that for the soft shell variety ‘Nonpareil’ and the three hard shell varieties of ‘Marcona’, ‘Tarraco’ and ‘Vyro’ that conditioning by soaking in water and resting before processing improves the recovery of undamaged kernel when shelling using impact. The impacts were applied by feeding the almonds into a rotating impellor and throwing them onto a stationary outer wall. An effective conditioning process resulted in the kernel moisture content increasing from 6% to 14% for hard shell and to 11% for ‘Nonpareil’ varieties. The conditioning process was measured to reduce the amount of scratched, chipped and broken kernel, and hence increased the recovery of undamaged kernel. After shelling, the conditioned kernel needed to be dried back to a 6% moisture content to be suitable for storage. Hence, the industry would be able to increase its recovery of undamaged kernel by changing to an impact shelling process using suitably conditioned almonds.
Opportunistic Routing Using Prioritized Forwarders with Retransmission Control
Authors: Yamazaki Taku , Yamamoto Ryo , Miyoshi Takumi , Asaka Takuya , Tanaka Yoshiaki 
Published: April 2017

Abstract
In ad hoc networks, broadcast-based forwarding protocols called opportunistic routing have been proposed. In general backoff-based opportunistic routing protocols, each receiver autonomously makes a forwarding decision using a random backoff time based on logical distance. However, each potential forwarder must wait for the expiration of the backoff timer before the packet forwarding. Moreover, they cannot gain forwarding path diversity in sparse environments. In this paper, we propose a novel forwarder selection method for opportunistic routing. In the proposed method, a terminal called, a prioritized forwarder, and which is selected from among neighbours and can forward packets without using the backoff time. In addition, we integrate a hop-by-hop retransmission control in the proposed method, which improves the packet transmission success rate in sparse environments. We evaluate the proposed method in comparison with the conventional protocols in computer simulations.
One or two species of the rare Malagasy carnivoran Eupleres (Eupleridae)? New insights from molecular data
Authors: Veron Géraldine , Goodman Steven M. 
Published: April 2017

Abstract
Members of the genus Eupleres are poorly known insectivorous carnivorans belonging to the family Eupleridae (order Carnivora), which are endemic to Madagascar. Recently, using morphological characters, the two previously recognized subspecies of Eupleres goudotii were raised to the species level, with E. goudotii occurring in the humid forests of the island, largely in the east, and Eupleres major in northwestern dry deciduous forests. Using some of the few museum specimens and fresh tissue samples available for this genus, we assessed differences between these two forms based on the cytochrome b gene. The results show that individuals identified as E. major, based on a combination of morphological characters and collection locality, do not form a monophyletic group, and the level of polymorphism within the genus is not in agreement with the recognition of two species. Additional molecular data, in particular from nuclear markers, are needed to verify these results.

Smart Thermal Grids – A Review
Authors: Stănişteanu Cristina 
Published: April 2017

Abstract
In line with the Renewable Energy Directive (2009/28/EC), EU member states have intensified their efforts to increase the share of renewable energy in energy supply. Renewable energy sources will be a challenge for the current district heating concept, requiring system flexibility both in terms of heat supply and heat consumption. Besides, they are hard to accommodate in areas with high population density, as it is the case with many towns and cities. The municipalities will have to identify suitable locations, which in turn will lead to distributed heat supply. The requirement of the 2010/31/EU (EPBD) Directive that all new buildings will have to be nearzero energy buildings will result in buildings fitted with solar collectors; some buildings will produce more energy than they can use. To accommodate all these challenges, the scientists have come up with the new concept of Thermal Smart Grids. The renewable energy will then be shared with the whole district heating grid, and the network will also be used for heat storage when consumption is lower than production. Smart thermal grids are expected to be an integrated part of the future smart energy systems, integrated electricity, gas and thermal grids.
Changes in persistence, spurious regressions and the Fisher hypothesis

Synthesis and crystal structure of the new vanadate AgCaVO4: Comparison with the arcanite structure
Authors: Nénert Gwilherm 
Published: April 2017

Abstract
We report the synthesis and the crystal structure of the new vanadate AgCaVO4 from laboratory powder X-ray data. Contrary to the previously reported AgBVO4 (B=Mg, Cd), AgCaVO4 exhibits the arcanite structure (β-K2SO4). Although it exhibits the same structure than arcanite, significant differences are observed. These differences are explained by deriving the atomic displacement field. The change of connectivity within the structure between β-K2SO4 and AgCaVO4 results from a rotation of the VO4 tetrahedra giving rise to a change from a face sharing to an edge sharing octahedral chains. Additionally, the thermal expansion of AgCaVO4 has been investigated up to 800°C.

Perspektivenwechsel und narrative Verdichtung: Hermeneutische Zugänge zum Thema Flucht im Religionsunterricht
Authors: Kumlehn Martina 
Published: April 2017

Zusammenfassung:
Der Beitrag verortet die Themen Flucht und Migration im Religionsunterricht. Er fokussiert existentielle Fluchterfahrungen und ihre religiösen Deutungshorizonte, um eine Kultur der wechselseitigen Anerkennung und Akzeptanz zu befördern. Im Zentrum steht eine Didaktik des Perspektivenwechsels, die zunächst die Wahrnehmungen zum Thema Flucht verlangsamt, kontrastiert und irritiert, um die Problematik der Sichtbarkeit von Flüchtlingen in ihrer Individualität und Identitätssuche zu reflektieren. Sodann werden biographische, literarische und biblische Erzählkontexte zu den Motivfeldern Exodus, Flucht und Gewalt, Heimatverlust und neue Heimat, radikale Entsicherung, Warten, Gottesfrage und Fluchterfahrungen verschränkt, um die narrative Identität und die Deutungs- und Ausdruckskompetenz in diesem Zusammenhang zu erweitern.
Bildung in Zeiten des Wandels. Konturen und Herausforderungen
Authors: Miedema Siebren 
Published: April 2017

Zusammenfassung:
Ein Interesse an Bildung ist dringend notwendig, weil neoliberale Spuren in Politik und Praxis immer noch deutlich vorhanden sind. Rein kognitive Ansätze sind zu kritisieren, auch vor dem Hintergrund der immer stärkeren Stimme von Religionswissenschaftlern im öffentlichen Bereich. Die verschwiegene Normativität derartiger Herangehensweisen unter Berufung auf Neutralität erfordert robusten und ständigen Widerspruch und eine Beteiligung an der öffentlichen Diskussion über religiöse und weltanschauliche Persönlichkeitsbildung. Allgemeinpädagogen und Religionspädagogen werden angesprochen, noch mehr ihre Rolle als öffentliche Intellektuelle wahrzunehmen: Denn die weltanschauliche Pluralität erfordert die Pluralitätsfähigkeit als eine Basiskompetenz aller Schülerinnen und Schüler.
