Time‐Dependent Changes in the Structure of Calcified Fibrocartilage in the Rat Achilles Tendon–Bone Interface With Sciatic Denervation
Authors: Takahashi Hideaki , Tamaki Hiroyuki , Oyama Mineo , Yamamoto Noriaki , Onishi Hideaki 
Published: September 2017

ABSTRACTThe enthesis transmits a physiological load from soft to hard tissue via fibrocartilage. The histological alterations induced by this physiological loading remain unclear. This study was performed to examine the histomorphological alterations in the collagen fiber bundle alignment and depth of collagen interdigitation between the calcified fibrocartilage and the bone. We examined the Achilles enthesis of rats with sciatic denervation to explore the mechanical effects of structural changes in the enthesis. The parallelism of the collagen fiber bundles was significantly reduced 8 weeks after denervation. However, the depth of collagen interdigitation significantly increased at 2 and 4 weeks after denervation and then significantly decreased 8 weeks after denervation. In conclusion, a lack of muscle loading induced structural alterations in the distal calcified fibrocartilage. These findings suggest that while structural changes in the enthesis are necessary for the development of physiological loading, structural deformities are required in the long term.

AbstractA series of unsymmetrical (D‐A‐D1, D1‐π‐D‐A‐D1, and D1‐A1‐D‐A2‐D1; A=acceptor, D=donor) and symmetrical (D1‐A‐D‐A‐D1) phenothiazines (4 b, 4 c, 4 c′, 5 b, 5 c, 5 d, 5 d′, 5 e, 5 e′, 5 f, and 5 f′) were designed and synthesized by a [2+2] cycloaddition–electrocyclic ring‐opening reaction of ferrocenyl‐substituted phenothiazines with tetracyanoethylene (TCNE) and 7,7,8,8‐tetracyanoquinodimethane (TCNQ). The photophysical, electrochemical, and computational studies show a strong charge‐transfer (CT) interaction in the phenothiazine derivatives that can be tuned by varying the number of TCNE/TCNQ acceptors. Phenothiazines 4 b, 4 c, 4 c′, 5 b, 5 c, 5 d, 5 d′, 5 e, 5 e′, 5 f and 5 f′ show redshifted absorption in the λ=400 to 900 nm region, as a result of a low HOMO–LUMO gap, which is supported by TD‐DFT calculations. The electrochemical study exhibits reduction waves at low potential due to strong 1,1,4,4‐tetracyanobuta‐1,3‐diene (TCBD) and cyclohexa‐2,5‐diene‐1,4‐ylidene‐expanded TCBD acceptors. The incorporation of cyclohexa‐2,5‐diene‐1,4‐ylidene‐expanded TCBD stabilized the LUMO energy level to a greater extent than TCBD.

AbstractA recent scientific discipline, bioinformatics, defined as using informatics for the study of biological problems, is now a requirement for the study of biological sciences. Bioinformatics has become such a powerful and popular discipline that several academic institutions have created programs in this field, allowing students to become specialized. However, biology students who are not involved in a bioinformatics program also need a solid toolbox of bioinformatics software and skills. Therefore, we have developed a completely online bioinformatics course for non‐bioinformaticians, entitled “BIF‐1901 Introduction à la bio‐informatique et à ses outils (Introduction to bioinformatics and bioinformatics tools),” given by the Department of Biochemistry, Microbiology, and Bioinformatics of Université Laval (Quebec City, Canada). This course requires neither a bioinformatics background nor specific skills in informatics. The underlying main goal was to produce a completely online up‐to‐date bioinformatics course, including practical exercises, with an intuitive pedagogical framework. The course, BIF‐1901, was conceived to cover the three fundamental aspects of bioinformatics: (1) informatics, (2) biological sequence analysis, and (3) structural bioinformatics. This article discusses the content of the modules, the evaluations, the pedagogical framework, and the challenges inherent to a multidisciplinary, fully online course. © 2017 by The International Union of Biochemistry and Molecular Biology, 46(1):31–38, 2018.
Institutional Pressures and Environmental Management Practices: The Moderating Effects of Environmental Commitment and Resource Availability
Authors: Wang Shanyong , Li Jun , Zhao Dingtao 
Published: September 2017

AbstractWith the deterioration of the environment and the shortage of natural resources, firms are facing increasing pressures to implement environmental management practices in their daily operation management. Drawing on institutional theory and environmental management literatures, this research tries to explore how institutional pressures motivate firms to implement environmental management practices, and how such effects are moderated by firms' environmental commitment and resource availability. The results of a survey of 188 Chinese firms suggest that regulatory pressures and normative pressures are positively and significantly related to firms' propensity to implement environmental management practices. Moreover, the results indicate that firms' environmental commitment positively moderates the relationships between institutional pressures and environmental management practices, while firms' resource availability plays different roles depending on the types of pressure (regulatory or normative pressures). Implications and suggestions for future research are provided. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment
The supervisory alliance: Comparison of measures and implications for a supervision toolkit
Authors: Schweitzer Robert D. , Witham Merryn 
Published: September 2017

AbstractBackground Clinical supervision lies at the core of the professional development of clinicians providing services within a range of service settings. The supervisory alliance is regarded as the most important construct in effective supervision which underlies the importance of metrics to assess this construct. Aims materials and Method A cross‐sectional self‐report questionnaire design was used to examine clinical supervision constructs. The study used two scales measuring the supervisory alliance (SRQ and SWAI‐T), a scale measuring supervision satisfaction (SSQ) and a scale measuring disclosure (TDS). The questionnaires were administered to 127 clinical psychology trainees who were undertaking a practicum placement. Results Both scales measuring the alliance were positively correlated with satisfaction with supervision and disclosure, with similar sizes of correlation for each alliance scale. There was also a large, positive correlation between the two scales of measuring the alliance. Discussion Both scales were designed for use in supervision and are related to supervision outcome measures in the expected directions. Conclusion The SRQ has some distinct advantages over the SWAI‐T that lend the SRQ to be potentially more useful in clinical and research settings.
Academic Disputes about Adult‐Child Sexual Contact: A Critical Realist Appraisal
Authors: Pilgrim David 
Published: September 2017

This paper examines the difference between the orthodox assumption that adult‐child sexual contact is both wrong and harmful and another that focuses upon moral panics. The latter view emphasises that the personal or social harm arising from adult‐child sexual contact is open to question. The tension between these two positions is laid out in order to examine their different assumptions about what exists (ontology), how it is understood (epistemology) and how we appraise power discrepancies in relationships (ethics). Resources from the philosophy of critical realism are deployed to critique the applicability of moral panic theory to child sexual abuse and understand the persistent presence of that theory, despite its poor evidence base. It is concluded that child sexual abuse is not a moral panic at all and that practitioners should be wary of the influence of this line of reasoning in their professional training and literature.‘Examines the difference between the orthodox assumption that adult‐child sexual contact is both wrong and harmful and another that focuses upon moral panics’Key Practitioner Messages

A minority academic position is that adult‐child sexual contact is usually harmless and ethically and psychologically warranted in society. Public and professional concern about the contact is depicted as a ‘moral panic’.
The recent history of that minority position is examined and justifications from policy libertarians and pro‐paedophile groups summarised.
Using resources from the philosophy of critical realism, this position is critiqued for its unwarranted reliance on the assumption that adult‐child sexual contact has become a moral panic.

Published: September 2017

AbstractA new mild and efficient process for the aqueous preparation of aldehydes, which are employed as flavour and fragrance components in food, beverage, cosmetics, as well as in pharmaceuticals, was developed using a continuous‐flow approach based on an immobilised pure transaminase‐packed bed reactor. HEWT, an ω‐transaminase from the haloadapted bacterium Halomonas elongata, has been selected for its excellent stability and substrate scope. Sixteen different amines were rapidly (3–15 min) oxidised to the corresponding aldehydes (90 to 99 %) with only 1 to 5 equivalents of sodium pyruvate. The process was fully automated, allowing for the in‐line recovery of the pure aldehydes (chemical purity >99 % and isolated yields above 80 %), without any further work‐up procedure.

Published: September 2017

AbstractA facile method for the synthesis of unsaturated organoboron compounds by hydroboration of terminal and internal alkynes in supercritical (sc) CO2 has been presented for the first time. The reactions performed in scCO2 in the presence of Ru catalysts (selectivity, productivity) are compared with those in a traditionally used solvent or without it. Moreover, the catalytic systems based on the application of scCO2 have been successfully tested for the processes under repetitive batch conditions. This strategy permitted us to obtain boryl‐substituted olefins with high yields and selectivities up to the 16th catalytic cycle if using Ru(CO)Cl(H)(PPh3)3 as a catalyst. The process applied the self‐dosing catalyst, which is gradually released to the reaction mixture under supercritical conditions in the individual batch. Such an approach has a positive impact on process sustainability and economy.
Intermediates in the Oxidative Degradation of a Ruthenium‐Bound 2,2′‐Bipyridyl–Phenoxy Ligand during Catalytic Water Oxidation

Published: September 2017

AbstractWater‐oxidation catalysts (WOCs) based on transition‐metal complexes often undergo oxidative degradation of the ligands, which leads to unidentifiable products. We report herein the use of a ruthenium(III) complex bearing a 2,2′‐bipyridyl (bpy)–bis(phenoxy) ligand, [Ru(L)(pic)2]+ [1, H2L=6,6′‐bis(2‐hydroxyphenyl)‐2,2′‐bipyridine, pic=4‐picoline] as a WOC. The phenoxy‐type ligand in 1 is readily oxidized by CeIV in aqueous acidic medium to give a ruthenium bpy–dicarboxylate complex ([Ru(bda)(pic)2]+, H2bda=2,2′‐bipyridine‐6,6′‐dicarboxylic acid) via ruthenium bpy–phenoxybenzoquinone (1′) and ruthenium bpy–bis(benzoquinone) (1′′) intermediates. All four ruthenium species can oxidize water; however, 1 and 1′ are rapidly oxidized to 1′′ by CeIV. On the other hand, 1′′ is robust enough that it is responsible for the initial phase of O2 evolution before it is finally oxidized to CO2 and [Ru(bda)(pic)2]+, which is a highly active WOC.
03.18: Anchor bolt tensile load distribution: Effects of the column base‐plate design: Wide flange column bases – loading on additional line of bolts
Authors: de Macedo Rafael Scudelari , de Macedo Luiz Francisco Scudelari 
Published: September 2017

ABSTRACTThe designer of column base elements usually considers that the uplift force existing in the column member is equally distributed on its anchor bolts. While this simplified approach may be used for the most common cases of a steel structures (for instance, when only 4 equally spaced anchor bolts exist in the column base design), it may lead the designer to overlook that the distribution of uplift loads is highly influenced by factors such as the rigidity of the base plate, the positioning of its stiffeners and the number and geometric arrangement of the anchor bolts. This unequal distribution of uplift loads on the anchor bolts may cause overloading on some of the anchor bolts, leading to diverting failure. This paper analyses through finite element several different wide‐flange column base elements, with varying plate thicknesses and geometry. The conclusion summarizes that the distribution of the loads on the anchor bolts largely depend on the typology of the base plate and suggests a revision of the codes to be more precise on when unequal axial tensile loads may arise on the anchor bolts and recommend more refined methods for the estimation of those unequally distributed loads.
03.21: Structural glued connections with different metal substrates

Published: September 2017

ABSTRACTIntensive studies of polymer adhesives for structural applications have opened up new possibilities of glued usage connections in civil engineering, especially in façade applications. Facades have to fulfil not only architectural requirements but there are also construction and material technology requirements, as well as functionality. Façade cladding connections with other façade parts can be advantageously designed as glued joints. In dependence on particular application, adhesive bonding provides higher efficiency of workmanship in comparison with bolted connection and esthetical qualities, e.g. smooth, flat surface of façade cladding without visual interruption of bolts. Important benefit of glued connections in facades is elimination of local thermal bridge in comparison with bolted connections and possibility of stress peak reduction in dependence on adhesive and substrate stiffness and geometrical arrangement of the joint. Despite of wide usage of low strength and elastic silicone sealants for a long period of time in façades, there is a lack of information about semi‐flexible and semi‐rigid adhesives with higher strength and reasonable elongation at break. Building facade is a very specific type of usage for glued connections due to the requirements on durability, strict geometrical imperfections and joining of unconventional materials often used in the façade design. This paper reports on an experimental analysis focused on determining of the mechanical characteristics of two types of adhesive applied in double lap connection loaded by shear. The study comprises two basic substrate materials, aluminium and galvanised steel, with various surface treatments. Galvanized steel was used with clean, smooth surface and roughened surface; aluminium substrates were applied with clean smooth surface, roughened surface and with anodised covering to find out effect of roughening and anodization of aluminium on adhesion. Material and surface treatment has great influence not only on adhesion and thus strength of the joint, but also on failure mode, behaviour and safety of particular joint. Moreover, every necessary surface treatment creates higher labour intensity, higher time consumption and thus increased costs on building/facade construction.

Published: September 2017

ABSTRACTSquare steel tubular(SST) column and H‐shaped steel(HSS) beam systems have been widely used in engineering applications. The structural performance of this system largely depends on the behavior of the connections. This paper presents a new type of connections with bottom‐through‐diaphragm and top‐ring. Five specimens were tested under cyclic loadings to evaluate the seismic behavior and the moment‐rotation relationships. Finite element models were developed and compared with experimental testing to verify the accuracy of the model. The calculation equation of moment‐rotation curves were proposed according to the analytical data of finite element model. Furthermore, the moment‐rotation calculation model characterizing the general behavior of this new type connection were developed based on these parameters. The accuracy of the calculation model was examined by comparing with the results of finite element model. Finally, a reasonable moment‐rotation relationship was obtained using the parameters within this model.
03.34: European stiffened angle connections: Numerical study

Published: September 2017

ABSTRACTIt is a fact, from experimental observations, that all connections used in current practice possess stiffness which fall between the extreme cases of fully rigid or ideally pinned joints. The characterization of the real semi‐rigid behavior of connections must be properly modeled in order to reliably predict the response of the structural frame. The use of bolted cleat angle connections is characterized by substantial economical benefits essentially due to the ease in the erection process. Moreover, this kind of connection enhances both deconstructability and reusability since it preserves the independence of the members. Finally, angle connections are highly recommended for designing in seismic areas instead of welded connections to avoid brittle fracture.One of the main parameters in connection design is the joint stiffness. The initial stiffness of angle connections could be increased by introducing stiffeners in the joint design. In this paper, numerical a study for the analysis of the rotational stiffness of stiffened angle connections is dealt with. This work was carried through on semi‐rigid angle connections with stiffened top and seat angles. Advanced 3D Finite Element models were developed on the geometrical configuration of future experimental tests. On the other hand, the numerical results of varying the joint configuration are discussed. Once these FE simulations had been checked with the experimental tests, they can be used to undertake future parametric studies on the main joint parameters and also for the validation of analytical proposals that can be very useful in common practice of joint design.
04.02: Plastic behaviour of polygonal hollow sections in bending
Authors: Rohr Katharina , Knoedel Peter , Ummenhofer Thomas 
Published: September 2017

ABSTRACTSteel poles of polygonal sections are an economic alternative to circular hollow sections for use as lighting towers or transmission line pylons. Especially for transmission lines, the design of the poles is intended to become more compact to avoid land usage and to obtain an inconspicuous appearance. If the pole diameter is reduced, the slenderness of the sections needs to be reduced as well to achieve the desired resistance, but an increasing wall thickness disproportionately reduces the cost‐effectiveness of the structure. The European design rules for overhead electrical lines [1] do not allow using the plastic behaviour of stocky sections, which reduces the advantages of compact sections.In modern standards for steel structures, such as Eurocode 3 (EC3) [2], activating plastic reserves is generally acknowledged state of the art. According to EC3‐1‐1, the slenderness of the profile decides on the allocation to cross section class 1 or 2, where plastic design is allowed, class 3, where only elastic behaviour is used or class 4, where local buckling is assumed. When changing from class 2 to class 3 sections, this standard provides a sudden drop in resistance, which has long been recognised to be unjustified. Research has been done to overcome this mismatch for circular hollow sections [3].In this paper the transition between the plastic bending moment capacity and the limit state of buckling is investigated to identify the ultimate load of polygonal sections. The investigated polygon of 16 edges can be treated as a collection of plate strips using the plate buckling design rules EC3‐1‐5 for cross sections class 4. Detailed examinations illustrate the inconsistency of EC3 in the bending capacity of compact sections right before the start of stability problems.On the basis of experimental data gained from full‐scale bending tests, along with imperfection measurements via laser scanning, numerical investigations have been performed. These results suggest that the bending moment capacity can be increased above the calculated elastic capacity with more compact sections, but might be overestimated when calculating the full plastic capacity according to EC3‐1‐1.
04.06: Post‐buckling strength of plate girders subjected to shear: Experimental verification
Authors: Hansen Thomas 
Published: September 2017

ABSTRACTThis paper describes a calculation method for steel plate girders with transverse web stiffeners subjected to shear. It may be used for predicting the failure load or, as a design method, to determine the optimal amount of internal web stiffeners. The method is based on the theory of plasticity. Many other theories have been developed, but the method presented differs from these theories by incorporating the strength of the transverse stiffeners and by the assumption that the tensile bands may pass the transverse stiffeners, which often is observed in tests. Other methods have only dealt with a single web field between two stiffeners.The load‐carrying capacity may be predicted by applying both the lower‐bound theorem and the upper‐bound theorem. The upper‐bound solutions have shown very good correlation with existing tests. The emphasis is attached to the presentation of the tests conducted at the Technical University of Denmark. The test programme contained six full scale plate girder specimens. The agreement between the theory and the tests is very good.
