Schiebetürbeschläge für Verbundsicherheitsglas mit lastabtragender Verklebung
Authors: Hartwig Peter , Winkler Sascha , Kothe Michael 
Published: June 2015

AbstractNeben Einscheibensicherheitsglas (ESG) kommt heute bei Ganzglas‐Innentüren vermehrt auch Verbundsicherheitsglas (VSG) aus ESG zum Einsatz. Der Verbund bei VSG bietet eine erhöhte Sicherheit und die Möglichkeit mit speziellen Folien einen zusätzlichen Schallschutz sowie gestalterische Akzente zu realisieren. Bricht das Glas unter extremer mechanischer Belastung, so sorgt die hohe Reißfestigkeit der Folie für eine entsprechende Resttragfähigkeit. Dafür bietet DORMA‐Glas GmbH für das manuelle Schiebetürsystem AGILE 150 modifizierte Klemmlaufwagen an, die mit einer speziellen beidseitigen Verklebung der Beschläge am Glas sicher halten und die reduzierte Klemmkraft ausgleichen. Sie verhindern ein Absenken der Türblätter auch bei hoher Belastung in stark frequentierten Bereichen. Die Leistungsfähigkeit der Klebung hinsichtlich der erwarteten Belastungen soll über Traglastversuche an großformatigen Prüfkörpern sowohl unter kurzzeitiger als auch unter dauerhafter Beanspruchung experimentell nachgewiesen werden.Sliding door fittings for laminated safety glass with load‐bearing bonding. In addition to toughened glass, all‐glass sliding doors are now increasingly realized with laminated safety glass. The composite of laminated safety glass offers a higher security and allows the possibility for better sound insulation by using modified interlayer materials. The high tensile strength of the interlayer provides an appropriate residual bearing capacity in case of glass breakage under extreme mechanical stress. DORMA‐Glas GmbH offers a modified clamping carriage for the manual sliding door systems AGILE 150 with a special double‐sided bonding of the fittings to the glass. They prevent a lowering of the door leaves even under high loads in highly frequented areas. The performance of the bonding in terms of the expected loads should be experimentally proved via load test on large‐size specimens under short‐term and permanent loads.

AbstractIn moderner Architektur sind Stahl‐Glas‐Fassaden prägnante Gestaltungselemente. Während in der Vergangenheit Stahl‐Glas‐Fassaden üblicherweise mit geschraubten Punkthaltern montiert wurden, findet man inzwischen bei vielen dieser Fassaden stattdessen verklebte Rahmenstrukturen. Die nachfolgend beschriebenen Arbeiten befassen sich mit mehrachsigen Spannungszustände in solchen geklebten Verbindungen, wie bspw. bei L‐förmigen Klebfugen. Sowohl experimentelle Untersuchungen als auch numerische Simulationen (unter Verwendung von verschiedenen, bereits vorhandenen hyperelastischen Materialmodellen) wurden innerhalb der Untersuchungen durchgeführt, um insbesondere die verschiedenen Materialmodelle zu vergleichen. Hierzu wurden Bauteilversuche an zwischen 6 und 15 mm dicken Glasscheiben durchgeführt und numerisch simuliert, unter Verwendung von zwei verschiedenen Klebstoffsystemen: einem 2K‐Silikon und einem 1K‐Polyurethan.Multi‐axial stress‐strain behaviour of bonded structural steel‐glass facade panels. In today’s building, architecture the application of modern structural steel‐glass facades is very popular. While the typical assembly of such steel‐glass facades used to be with bolted point fixings, more and more facade panels are now designed using multi‐side bonded joints. The work described in this paper deals with multi‐axial stress states in bonded joints, e.g. with L‐shaped edge frame. Both experimental testing as well as numerical calculations have been carried out, leading to a thorough comparison of different numerical models. Large‐scale component tests were performed with two different adhesives (a 2C silicone and a 1C polyurethane) on glass plates between 6 and 15 mm thick.

AbstractGlas wird nicht nur als transparente Ausfachung von Öffnungen in der Fassade eingesetzt, sondern dient ebenfalls als gestalterisches Element in der Gebäudehülle. Die Vielfalt an Bedruckung, Farb‐ und Formgebung ist gross. Vielschichtig sind aber auch die Anforderungen an Temperatur‐ und Witterungsbeständigkeit, Gestaltung, Sicherheit, Verarbeitung und Wirtschaftlichkeit. Hier werden durch die Entwicklung einer multifunktionalen Silikonapplikation neue Möglichkeiten eröffnet. Durch die direkte und vollflächige Verklebung von gläsernen Deckschichten mit der rückwärtigen Tragstruktur können diverse Funktionen in der Klebschicht vereint werden. Dieser Beitrag zeigt neue Möglichkeiten der konstruktiven Umsetzung und der rechnerischen Bemessung auf.Approach of designing composite panels with laminar applied silicone adhesive. Glass is not just a transparent skin used to cover openings in curtain wall units. Additionally it is an architectural element what forms the face of a building. The diversity of prints, colors and shapes is huge. But there is also a variety of demands on temperature and weathering resistance, design, safety, processing and profitability. Referring to that, the development of a multifunctional silicone application opens new opportunities. Realizing a direct and laminar bonding between a cover made of glass and the load‐bearing structure on the backside, several functions can be combined in the silicone layer. This paper shows opportunities of structural design and calculation.

Thermisch vorgespannte Gläser für den Architekturbereich ohne optisch wahrnehmbare Anisotropien
Authors: Dehner Hermann , Schweitzer Albert 
Published: June 2015

AbstractDas Thema Anisotropie findet zunehmend mehr Bedeutung in Spezifikationen von Gläsern für den Architekturbereich. Meist findet man Angaben qualitativer Art. Konkrete Angaben oder gar Grenzwerte werden nicht festgelegt, da bislang keine Möglichkeiten einer messtechnischen Bewertung existierten. Die Bewertung von Mockups ist nicht geeignet und gegenüber keiner Partei zu vertreten, da Anisotropien in Abhängigkeit von der Lichtpolarisation unterschiedlich stark sichtbar sind. Durch die Verfügbarkeit einer Messapparatur wurde nun die Voraussetzung für eine objektive Bewertung geschaffen. Darauf aufbauend wurde eine optimierte Technologie entwickelt, welche die Herstellung von thermisch vorgespanntem Glas ohne störende Anisotropien ermöglicht.Thermally toughened glass panes for architectural applications without visible anisotropy. Anisotropy is becoming more important in glass specifications for architectural applications. On those specifications, there are usually just qualitative indications but no specific details or even limits or tolerances for anisotropy as up to now it was not possible to perform any objective evaluation. The review of mock‐ups is not suitable as anisotropy is more or less visible depending on the light polarization and therefore there is no party responsible. Due to the recent existence of a measuring device, the requirement of an objective assessment or evaluation of anisotropy is now possible. Based on this, an optimized technology has been developed and it enables the production of thermally toughened glass without disturbing anisotropy.

AbstractIn vielen Technologiegebieten ist Glas ein hoch geschätztes Material für Applikations‐ und Designzwecke. Speziell im Architektursektor ist der Anspruch an Funktionalität und Optik von Glasplatten signifikant gestiegen. Eine gleichmäßige, verzerrungsfreie Transparenz setzt makellose Oberflächen und Strukturen voraus. Homogenität, festgelegte Farbbeschichtung, Ebenheit und exakte Maßhaltigkeit sind weitere entscheidende Qualitätskriterien für Glasplatten. Hier kann eine kontinuierliche 100 %‐Qualitätsinspektion helfen. Der Vortrag gibt einen Überblick über neue, innovative optische Inline‐Inspektionslösungen – besonders in 3D – für optische Verzerrung, Ebenheit, Verzerrung in der Reflexion sowie für die vollautomatische Beschichtungs‐ und Farbprozesskontrolle, um einer Vielfalt von Qualitätsbedürfnissen gerecht zu werden.New optical inspection solutions and applications to assure best functionality and quality for architectural glass of tomorrow. Glass is a highly valued material in many areas of technology for application and design. Especial in the architectural sector the demand on functionality as well as on the visual appearance of glass sheets has risen significantly. Uniform, distortion‐free transparency requires flawless surfaces and structures. In addition, homogeneity, defined color coating, flatness and dimensional accuracy are critical quality attributes for glass plates. This is where continuous automatic 100 % quality inspection can help. The lecture will give an overview about new innovative inline optical inspection solutions – particular even in 3D – for optical distortion, flatness, reflected distortion as well as the full automatic coating and color process control to account for the variety of quality needs.

AbstractBei der in Teilen öffentlich zugänglichen, begeh‐ und erfahrbaren medizinischen Großforschungsanlage :envihab wurde in vorbildlicher Weise Glas eingesetzt. Das fein ausgewogene Verhältnis des transparenten Baustoffes zur massiven Hülle stellt einen anregenden Kontrast her. Das Glas erscheint als integraler Bestandteil und im besten Sinne entmaterialisiert, leicht und diaphan wie die Haut einer Zelle. Glas wird, dies ist so einfach wie selbstverständlich, eingesetzt, da es DER transparente Baustoff ist, und kein anderer Stoff so wie dieser Licht transmittiert. Neben der Schutzfunktion muss jedes Gebäude Licht, Luft und sonstige Ver‐ und Entsorgungsdienste etwa über die Haustechnik bereitstellen, für :envihab als Forschungslabor gilt dies im Besonderen.:envihab – German Aerospace Center, Institute of Aerospace Medicine. In the partially publicly available, accessible and tangible large‐scale medical research facility :envihab glass was used in an exemplary manner. The well‐balanced ratio of the transparent building material to the massive shell produces a stimulating contrast. The glass appears as an integral part and dematerialized in the best sense, light and diaphanous like the skin of a cell. As easy as a matter of course glass is used, because it is THE transparent building material. No other material offers as much transparency as glass. In addition to the protective function each building must provide light, air and other supply and disposal services through general building services for instance. This applies in particular to :envihab as a research laboratory.

Abstract
High fructose corn syrup (HFCS) is an alternative of liquid sweetener to sucrose that is isomerized by commercial glucose isomerase (GI). One-step production of 55 % HFCS by thermostable GI has been drawn more and more attentions. In this study, a new hyperthermophilic GI from Thermoanaerobacter ethanolicus CCSD1 (TEGI) was identified by genome mining, and then a 1317 bp fragment encoding the TEGI was synthesized and expressed in Escherichia coli BL21(DE3). To improve the activity of TEGI, two amino acid residues, Trp139 and Val186, around the active site and substrate-binding pocket based on the structural analysis and molecular docking were selected for site-directed mutagenesis. The specific activity of mutant TEGI-W139F/V186T was 2.3-fold and the value of k cat/K m was 1.86-fold as compared to the wild type TEGI, respectively. Thermostability of mutant TEGI-W139F/V186T at 90 °C for 24 h showed 1.21-fold extension than that of wild type TEGI. During the isomerization of glucose to fructose, the yield of fructose could maintain above 55.4 % by mutant TEGI-W139F/V186T as compared to 53.8 % by wild type TEGI at 90 °C. This study paved foundation for the production of 55 % HFCS using the thermostable TEGI.
Characterization of knee alignment in children with mucopolysaccharidosis types I and II and outcome of treatment with guided growth
Authors: Ashby Elizabeth , Eastwood Deborah 
Published: June 2015

Purpose To describe knee alignment in children of different ages with severe mucopolysaccharidosis (MPS) I and II and the outcome of treatment with guided growth in a patient subgroup. Methods This is a retrospective observational study of 58 knees in 29 children with severe MPS I and II. Long-leg standing radiographs were evaluated to determine mechanical axis deviation, mechanical lateral distal femoral angle and medial proximal tibial angle at different ages throughout childhood. The change in deformity in individual children over time is reported. 20 knees in 10 patients were treated with guided growth using eight-plates. Radiographic measurements were recorded at the time of plate insertion, at plate removal and at 1 year following removal. Results At 8 years of age, all MPS I children and three-quarters of MPS II children had valgus knee alignment. There was deformity progression in two-thirds of MPS I knees and half of MPS II knees. Guided growth corrected the deformities. There was recurrence in most cases 1 year after plate removal. Conclusions Knee deformity is common in children with severe MPS I and II. Guided growth can be considered where there is significant and/or or progressive deformity with the aim of halting progression and correcting existing deformity and thus minimizing the risk of gross deformity. Patients should be aware of the high rate of recurrence and the need for repeat surgery.
On full groups of non-ergodic probability-measure-preserving equivalence relations
Authors: LE MAÎTRE FRANÇOIS 
Published: June 2015

This article generalizes our previous results [Le Maître. The number of topological generators for full groups of ergodic equivalence relations. Invent. Math. 198 (2014), 261–268] to the non-ergodic case by giving a formula relating the topological rank of the full group of an aperiodic probability-measure-preserving (pmp) equivalence relation to the cost of its ergodic components. Furthermore, we obtain examples of full groups that have a dense free subgroup whose rank is equal to the topological rank of the full group, using a Baire category argument. We then study the automatic continuity property for full groups of aperiodic equivalence relations, and find a connected metric for which they have the automatic continuity property. This allows us to provide an algebraic characterization of aperiodicity for pmp equivalence relations, namely the non-existence of homomorphisms from their full groups into totally disconnected separable groups. A simple proof of the extreme amenability of full groups of hyperfinite pmp equivalence relations is also given, generalizing a result of Giordano and Pestov to the non-ergodic case [Giordano and Pestov. Some extremely amenable groups related to operator algebras and ergodic theory. J. Inst. Math. Jussieu6(2) (2007), 279–315, Theorem 5.7].

Cases were residents colonized with MDR (resistant to ≥3 classes of antibiotics)A. baumannii; controls were never colonized with MDRA. baumannii.METHODSFor active surveillance cultures, specimens from the nares, oropharynx, groin, perianal area, wounds, and device insertion site(s) were collected upon study enrollment, day 14, and monthly thereafter.A. baumanniistrains and their susceptibilities were identified using standard microbiologic methods.RESULTSOf 168 NH residents, 25 (15%) were colonized with MDRA. baumannii. Compared with the 143 controls, cases were more functionally disabled (Physical Self-Maintenance Score >24; odds ratio, 5.1 [95% CI, 1.8–14.9];P<.004), colonized withProteus mirabilis(5.8 [1.9–17.9];P<.003), and diabetic (3.4 [1.2–9.9];P<.03). Most cases (22 [88%]) were colonized with multiple antibiotic-resistant organisms and 16 (64%) exhibited co-colonization with at least one other resistant gram-negative bacteria.CONCLUSIONFunctional disability,P. mirabiliscolonization, and diabetes mellitus are important risk factors for colonization with MDRA. baumanniiin high-risk NH residents.A. baumanniiexhibits widespread antibiotic resistance and a preference to colonize with other antibiotic-resistant organisms, meriting enhanced attention and improved infection control practices in these residents.Infect Control Hosp Epidemiol 2015;36(10):1155–1162
Facies associations in warm-temperate siliciclastic deposits: insights from early Pleistocene eastern Mediterranean (Rhodes, Greece)

Published: June 2015

AbstractDiverse, abundant and usually well-preserved communities of skeletal organisms occur in the lower Pleistocene (Gelasian) siliciclastic deposits of the Greek island of Rhodes. Benthic foraminifers, molluscs and bryozoans have been studied in four measured and sampled sections located in the northern part of the island. Among these bottom-dwelling organisms, numerous extant taxa are good environmental indicators and, combined with field observations and sedimentological data, they provide information on the probable conditions in which they developed. The siliciclastic deposits of the Kritika Formation have been divided into 14 different bio- and lithofacies, which have been further grouped into four facies associations corresponding to four different environmental settings: (1) continental to fluviatile; (2) brackish-water (lagoonal/deltaic); (3) infralittoral (0–20 m); and (4) upper circalittoral (depths of 20–40 m, but also down toc.50–60 m). Among the marine facies associations, several characteristic biocoenoses have been recognized: soft-bottoms (fine to coarse sands and gravels); seagrass meadows; biogenic calcareous crusts on drowned beachrock slabs; red algal rhodoliths; and bivalve shell beds. In the studied sections, 13 superimposed genetic sequences have been documented. The repetition of similar facies associations within each sequence suggests: (1) a possibly eustasy-controlled, cyclic sedimentation; (2) a general subsidence of Rhodes during the deposition of the studied facies associations; and (3) a mostly constant range of environmental conditions (i.e. sedimentation rates and temperature) throughout the Gelasian.
