Authors: Eryuruk Selin Hanife , Kalaoğlu Fatma 
Published: September 2015

Abstract
The tear strength of a woven fabric is very important, since it is more closely related to serviceability of the fabric. Tearing strength of the fabrics depend on the mobility of the yarn within the fabric structure. In this study, the tearing strength of four types of fabrics warp rib, weft rib, ripstop and plain weave were analysed, which were produced in different densities and with filament and texturised polyester yarns.

Authors: Piskorski Ł. , Frasunkiewicz L. , Sarzała R.P. 
Published: September 2015

Abstract
In the present paper the results of the computer analysis of the GaAs-based and GaSb-based active regions that can be applied in compact semiconductor laser sources of radiation at mid-infrared wavelengths are presented. Quantum well material contents and strain dependencies on the maximal gain are investigated. It is shown that above 3 μm the maximal gain obtained for GaInNAs/AlGaInAs active region is high only for thick, highly-strained GaInNAs QWs with N concentration higher than 2%. Much higher gain in this wavelength range can be obtained for GaInAsSb/AlGaAsSb active region, which offers relatively high gain even at 4.5 μm when the Sb content in GaInAsSb and compressive strain in this layer are equal to 50% and − 2%, respectively.
An efficient algorithm for determining positions of astronomical objects in the Deep Sky Object pictures
Authors: Suszynski R. , Wawryn K. , Dziebowski M. 
Published: September 2015

Abstract
The article presents an algorithm for digital image processing of astronomical objects in order to effectively determine the position of these objects. The proposed method has been optimized due to its effectiveness of removing noise and distortion caused by atmospheric turbulence and imperfections in long exposure photography of astronomical objects. This solution is ready for implementation in a system for automatic identification of stars in the recorded images. Such a system is designed for GoTo circuits at telescope’s drives, which can automatically point a telescope to astronomical objects. The method was verified by simulation in MATLAB program on real images of astronomical objects.
Towards the boundary between easy and hard control problems in multicast Clos networks
Authors: Obszarski P. , Jastrzębski A. , Kubale M. 
Published: September 2015

AbstractIn this article we study 3-stage Clos networks with multicast calls in general and 2-cast calls, in particular. We investigate various sizes of input and output switches and discuss some routing problems involved in blocking states. To express our results in a formal way we introduce a model of hypergraph edge-coloring. A new class of bipartite hypergraphs corresponding to Clos networks is studied. We identify some polynomially solvable instances as well as a number of NP-complete cases. Our results warn of possible troubles arising in the control of Clos networks even if they are composed of small-size switches in outer stages. This is in sharp contrast to classical unicast Clos networks for which all the control problems are polynomially solvable.
Control of a planar robot in the flight phase using transverse function approach
Authors: Pazderski D. , Kozłowski K. 
Published: September 2015

Abstract
This paper deals with stabilization and tracking control problems defined with respect to a planar mechanical structure similar to Raibert’s robot. The proposed control solution is based on formal analysis of the control system on a Lie group. In order to take advantage of Lie group theory a dynamic extension of the robot kinematics is introduced. To cope with non-zero angular momentum the controller based on transverse functions is employed. Properties of the closed-loop control system are investigated based on simulations including practical stabilization at neighborhood of a constant point or a reference trajectory.
An ontology-based approach for integrating heterogeneous databases
Authors: Asgari Reza , Moghadam Milad Gholipoor , Mahdavi Mehregan , Erfanian Aida 
Published: September 2015

Abstract
Integrating heterogeneous data in distributed
databases has been a research issue for many years. In
this paper, we discuss some of these problems and propose
a solution using a semantic model. This semantic
model is built upon the semantic relationships between
existing data. Applying these semantics enables us to take
into account different dimensions of user queries and find
the best possible answer for them. The proposed approach
leads us to introducing "a common language that is understandable
for all databases". We use such a common language
in order to return an effective response to the user’s
query, as well as reducing the problems of integration.
Peer Observation For Online Distance Learning Tutors: Creating The Conditions For Effective Peer Exchange
Authors: Walker Richard 
Published: September 2015

Abstract
This article explores how online distance learning tutors working within a higher education context may be supported in their professional development through participation on an institutional peer observation programme. Drawing on the reflections of participants from two cohorts (2011 and 2012) at the University of York, the article reviews the learning outcomes arising from the peer observation process and investigates the necessary conditions for fostering critical reflection on practice between tutors. Feedback from participants highlighted the importance of investing time in relationship-building at the outset of the process - a necessary first step before free-ranging and critical exchanges can flourish between partners. Pairings which invested time at this stage appeared to develop greater levels of trust, enabling them to probe their tutoring practices in a more critical way and explore areas of perceived weakness as well as tackling emergent themes in their dialogue. These observations have informed the development of a guidance framework for peer exchange at the University of York, which is summarised in the concluding part of this paper.
A Systematic Review Of The Socio-Ethical Aspects Of Massive Online Open Courses
Authors: Rolfe Vivien 
Published: September 2015

English Abstract
Massive open online courses (MOOCs) offer learners across the globe unprecedented access to education. Through sophisticated e-learning technologies and web approaches, MOOCs attract massive scale participation and global interest. Some commercial ventures place social equality at the heart of their missions, claiming to empower communities by making education accessible and affordable. In reality, the socio-ethical impact of MOOCs has not been investigated fully, so it is not clear whether they meet these aspirations.
The aim of this study was to conduct a systematic literature review to examine the socio-ethical dimensions of MOOCs. The results showed a paucity of literature specifically addressing the subject in question, although there was evidence of many innovative approaches underway to examine new paradigms within learning analytics and online study behaviour that are emerging because of MOOCs. A small number of papers explored new pedagogic approaches such as conducting peer assessment on a massive scale, and how learning groups connect and establish on the open web.
To conclude, this paper begins to provide a framework on which to consider the socio-ethical dimensions of MOOCs. There is a need for good quality research to provide an evidence-base to ensure MOOCs deliver a socially equitable learning experience.

Published: September 2015

Abstract
Massive Open Online Courses (MOOCs) in the Arab World are still in their infancy. Many Arab countries are now starting to launch their MOOC platforms; however, there are only a few who have actually implemented such systems. This paper will explore online learning, in particular the rise of MOOCs around the world and their impact on the Arab World.
The purpose of this paper is to give a true picture of the development of the first MOOC platforms in the Arab World. It will analyse in detail the concept, definitions, background, and types of MOOCs (xMOOCs and cMOOCs), as well as the main MOOCs platform in the Western and Arab worlds, and a timeline of the development of MOOCs. It will then observe the status of MOOCs in the developed world, opportunities in the Middle East, and the influence of Western MOOCs on the Arab world, from many perspectives, e.g. educational, religious, cultural and social.

Published: September 2015

Summary
The current study aimed to investigate antimicrobial activity of methanol, ethanol, acetone, ethyl acetate and hot water (leaves and twigs fractions) Psidium guajava L. crude extracts against three bacteria and two fungi pathogens. Antimicrobial activity expressed by disc-diffusion assay (zone of inhibitions - ZIs), activity index (AI) and minimum inhibitory concentration (MICs) that were measured as reported in many investigations. Based upon the estimated ZIs, AI and MICs values, hot water twigs <1 cm diameter extract was the most potent against all tested microorganisms. The MICs value ranged between 4 and 7.2 mg/ml for bacteria, while, it was between 14.5 and 37.3 mg/ml for fungi. Moreover, ethyl acetate had the lowest antimicrobial activity compared to the other tested solvents. From the results obtained herein, it could be concluded that P. guajava serve as antibacterial and antifungal agent.
Experimental Development Of A Focalization Mechanism In An Integrated Narrative Generation System
Authors: Akimoto Taisuke , Ogata Takashi 
Published: September 2015

Abstract
“Focalization” is a narrative discourse technique that produces different narrative structures based on choosing unique perspectives from which to present a story. This study designs a focalization mechanism and presents an experimental implementation. The proposed system functions as part of our integrated narrative generation system (INGS). In addition, the approach computationally extends the conceptual research of focalization by Genette to techniques for narrative generation. We define focalization as a procedure to transform a story structure into discourse structures through the following two steps: 1) restricting the scope of story information perceived from a chosen perspective, and 2) generating a discourse structure based on perceived story information. In particular, we define two types of rules for restricting the perception scope based on: a) objective perceptible possibility of constituent elements in a story and b) situations or states in which constituent elements in a story are positioned. Based on the experimentally implemented system, we present generated examples from a story using different focalization types. Through analysis, we show that the basic function of the focalization mechanism was achieved by the aforementioned rules.

SummaryBachground: Sample classification and registration have been recognized as important and time-consuming processes in laboratories. There is increasing pressure on laboratories to automate processes due to intense workload and reduce manual procedures and errors. The aim of the present study was to evaluate the positive effects of an automatic tube registration and sorting system on specimen processing.Methods: An automatic tube registration and sorting system (HCTS2000 MK2, m-u-t AG, Wedel, Germany) was evaluated. Turnaround time (TAT), rate of sample rejection and unrealized tests were examined 12 months pre- and post-implementation of the automatic tube sorting and registration system.Results: The mean TAT of routine chemistry immunoassay, complete blood cell count (CBC) and coagulation samples were significantly improved (P<0.001). The number of rejected samples and unrealized tests was insignificantly decreased post-implementation of the system (0.4% to 0.2% and 4.5% to 1.4%, respectively) (P>0.05).Conclusions: By reducing delays and errors in the preanalytical processing and sorting of samples, significant improvements in specimen processing were observed after implementation of the system. These results suggest that an automatic tube registration and sorting system may also be used to improve specimen processing in a higher-volume core laboratory.
Solitons and Rogue Waves for a Higher-Order Nonlinear Schrödinger–Maxwell–Bloch System in an Erbium-Doped Fiber
Authors: Su Chuan-Qi , Gao Yi-Tian , Xue Long , Yu Xin 
Published: September 2015

AbstractUnder investigation in this article is a higher-order nonlinear Schrödinger–Maxwell–Bloch (HNLS-MB) system for the optical pulse propagation in an erbium-doped fiber. Lax pair, Darboux transformation (DT), and generalised DT for the HNLS-MB system are constructed. Soliton solutions and rogue wave solutions are derived based on the DT and generalised DT, respectively. Properties of the solitons and rogue waves are graphically presented. The third-order dispersion parameter, fourth-order dispersion parameter, and frequency detuning all influence the characteristic lines and velocities of the solitons. The frequency detuning also affects the amplitudes of solitons. The separating function has no effect on the properties of the first-order rogue waves, except for the locations where the first-order rogue waves appear. The third-order dispersion parameter affects the propagation directions and shapes of the rogue waves. The frequency detuning influences the rogue-wave types of the module for the measure of polarization of resonant medium and the extant population inversion. The fourth-order dispersion parameter impacts the rogue-wave interaction range and also has an effect on the rogue-wave type of the extant population inversion. The value of separating function affects the spatial-temporal separation of constituting elementary rogue waves for the second-order and third-order rogue waves. The second-order and third-order rogue waves can exhibit the triangular and pentagon patterns under different choices of separating functions.
Hydrolysis of 8-(pinacolboranyl)quinoline: where is the 8-quinolylboronic acid?
Authors: Son Jung-Ho , Tamang Sem Raj , Yarbrough Jason C. , Hoefelmeyer James D. 
Published: September 2015

Abstract
The compound 8-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-quinoline was prepared and found to hydrolyze rapidly in air; however, the expected product (quinolin-8-yl)boronic acid was not observed. Instead, the (quinolinium-8-yl)trihydroxyborate zwitterion or an anhydride were observed depending on the conditions of hydrolysis. The two products are related to one another in the degree of hydration, and the two forms could be interconverted. Both hydrolysis products were structurally characterized. Additionally, a commercial sample of ‘8-quinolylboronic acid’ was actually found to be the anhydride. The results call into question whether monomeric (quinolin-8-yl)boronic acid can actually be isolated in the neutral Lewis base-free form.
N-vinylation and N-allylation of 3,5-disubstituted pyrazoles by N–H insertion of vinylcarbenoids
Authors: Gill Agagia , Werz Udo R. , Maas Gerhard 
Published: September 2015

AbstractA vinylcarbenoid approach toward N-functionalization of NH-pyrazoles is presented. The rhodium(II)-catalyzed reaction of methyl styryl-diazoacetate (1) or dimethyl 2-diazoglutaconate (3) with 3,5-disubstituted pyrazoles gave products of carbenoid N–H insertion in high combined yields, although regioselectivity issues posed by the pyrazole or the vinylcarbenoid moiety as well as positional and configurational isomerism concerning the C,C double bond of the latter led to product mixtures. The ambident reactivity of the vinylcarbenoid derived from1could be steered by the catalyst: while Rh2(OAc)4yielded products of direct carbenoid insertion preferentially, silver(I) catalysis strongly favored reaction at the vinylogous site of the carbenoid resulting in an N-allylation of the pyrazoles.

Published: September 2015

AbstractManganese(II) biphenyl-4,4′-dicarboxylate, prepared by crystallization of a mixture of biphenyl-4,4′- dicarboxylic acid, manganese(II) chloride, and di(4-pyridyl)acetylene as base in a mixture of dimethylformamide, ethanol and water in a closed vessel at elevated temperatures forms a 3D network of {[Mn(bpdc)(H2O)2][Mn(bpdc)(H2O)]} containing one five-fold coordinated and one six-fold coordinated Mn metal center (X-ray structure determination). Scanning tunneling microscopic (STM) measurements of manganese biphenyl-4,4′-dicarboxylate adsorbed on highly oriented pyrolytic graphite showed strands, the averaged diameter of which amounts to 18±1 nm, whereas the apparent height is about 0.5±0.02 nm.

Authors: Song Eun Kyoo , Seon Jong Keun , Agrawal Pranav R. 
Published: September 2015

Case:
It is rare to find a case report on combined recurvatum and valgus deformity of the knee with associated patellar instability due to a depressed lateral tibial plateau in a young adult with multiple epiphyseal dysplasia. We treated such a patient with single-stage osseous and soft-tissue procedures and achieved a stable, well-aligned, pain-free, and mobile joint.

Conclusion:
Patellar instability with genu recurvatum and genu valgum leading to reduced range of motion of the knee in multiple epiphyseal dysplasia shows mechanical and functional improvement following single-stage surgical intervention, thereby improving quality of life.
Vicarious Learning under Implicit Contracts
Authors: Choi Jongwoon (Willie) , Hecht Gary , Tafkov Ivo D. , Towry Kristy L. 
Published: September 2015

ABSTRACT
Employee contracts often allow for managerial discretion, such that the manager decides after observing an employee's performance how that employee will be rewarded or penalized. Importantly, the effects of such evaluation outcomes can extend beyond the employee(s) directly affected, because such outcomes can be observed by other employees within the firm. The net effect of such vicarious learning as an indirect control depends on the inferences employees make after observing a peer's evaluation outcome. In this study, we use an experiment to investigate whether the inferences observer-employees make about how managers evaluate and reward employee behavior depend on whether the valence of the observed outcome is positive or negative. Using the setting of a strategic performance measurement system, we test and find support for a causal model, in which the valence of the observed outcome influences observer-employees' inferences and subsequent behavioral focus via their psychological distance from, and their construal of, the observed outcome. Our results suggest that how observer-employees respond after observing a peer employee's evaluation outcome is asymmetric. Specifically, when contemplating their own behavior, employees who observe positive outcomes focus on the performance measures within the strategic performance measurement system, whereas those who observe negative outcomes focus on the underlying strategic construct.
Growth Response Of Container Grown Japanese Azalea And Euonymus And Concentration Of Nitrates And Phosphates In The Runoff Water Under Different Irrigation And Fertilization
Authors: Matysiak Bożena 
Published: September 2015

Abstract
In this study a growth response of two container-grown ornamentals (Euonymus japonicus ‘Ovatus Aureus’ and Rhododendron ‘Geisha Orange’) grown under different irrigation and fertilization rates was examined. The content of nitrogen (N) and phosphorus (P) in the plant leaves and in leachates was measured. Two levels of irrigation – standard irrigation (SI) and – high irrigation rate (HI), and three control-release fertilizers (CRFs) – Multicote 17-17-17, Osmocote Exact Standard 16-9-12 and Plantacote 15-10-15, applied at the rate of 1.5, 3.0 or 4.5 g·l−1, were applied. Fast-acting fertilizers were used as the control. HI adversely affected the growth and quality of Euonymus but stimulated the growth and increased quality of Rhododendron within two years of cultivation in relation to SI. There were no significant interactions between the irrigation and fertilization treatments; irrespective of water regimes, growth responses of both plant species to used fertilizers were similar. Osmocote and Plantacote at the rate of 3 g·l−1 were the most effective for the growth of Euonymus and Rhododendron plants, except of Euonymus in the second year, when 4.5 g·l−1 CRFs resulted in the best growth of plants. HI increased the amount of runoff water as well as N-NO3 and P-PO4 losses from containers during the entire growing period, irrespective of a fertilizer type. The amount of the nitrate and phosphate in leakage was higher when higher rates of CRFs were applied. Maximum nitrate concentration in leakage was the highest 14 days after the application of CRFs.
