The challenge of meeting children's mental health needs
Authors: Membride Heather , McFadyen Jackie , Atkinson John 
Published: February 2015

Ensuring the mental health and wellbeing of children and young people should be a key public health priority. However, unless school nurses are adequately educated, trained and supported, they will be unable to develop the necessary skills required to contribute to improved outcomes for children and young people with mental health and wellbeing issues. This article discusses the results of unpublished research, carried out by the authors in 2009, examining the range of mental health issues school nurses in one Scottish NHS health board encounter in their day-to-day activities and whether they are adequately trained and supported to meet the mental health needs of these children and young people.
A decade of WikiLeaks: So what?
Authors: Christensen Christian 
Published: February 2015

Abstract
In this article, I consider how WikiLeaks has gone through a series of metamorphoses: from a small, relatively unknown website devoted to giving whistleblowers space to release their material to one of the best-known activist organizations in the world. In addition, it has gone from being an organization that began by operating as an alternative to the mainstream media, to one that worked with the mainstream, and then to a group that devoted a fair degree of energy to attacking the media. I argue that during this tumultuous period of change, WikiLeaks needs to be understood in relation to its impact upon a number of fundamental relationships central to the study of media and journalism. I use WikiLeaks to consider the importance of studying sites and organizations as cultural artefacts, and to examine the idea that ‘everything which has been collected on it, becomes attached to it-like shells on a rock by the seashore forming a whole incrustation’. Academic research itself is, of course, part of this incrustation.
Scholar-practitioner collaboration in media-related interventions: A case study of Radio La Benevolencija in Rwanda
Authors: Kogen Lauren , Price Monroe E. 
Published: February 2015

Abstract
What methodological, ethical or other issues arise in ‘media development’ projects that are collaborations between practitioners and scholars? This article uses as a case study a project led by Radio La Benevolencija (RLB) that sought to address inter-ethnic conflict in Rwanda through a radio drama programme – a Romeo and Juliet story of a forbidden love between members of two conflicting tribes. The intervention was unique in its attention to theories of communication and psychology in its design and implementation, and in its efforts to bring in academics throughout the course of the project to aid in design and evaluation. The authors, commissioned to conduct an evaluation of RLB’s past ten years of work, analyse the intervention in the context of Rwanda’s history and the organization’s use of theory, research and evaluation in their programmes. The authors find that, based on the RLB experience as well as evidence provided by communication and media research, the RLB model for peacebuilding through the media can be usefully adapted to other contexts, given particular parameters. The article concludes by arguing that the collaboration provides evidence of the fruitful ground that can and should exist between practice, theory and research, while problematizing challenges involved in such collaborations.

Quill Injury – Cause of Death in a Captive Indian Crested Porcupine (Hystrix Indica, Kerr, 1792)
Authors: Švara Tanja , Zdovc Irena , Gombač Mitja , Pogačnik Milan 
Published: February 2015

Abstract
Indian crested porcupine (Hystrix indica) is a member of the family of Old World porcupines (Hystricidae). Its body is covered with multiple layers of quills, which serve for warning and attack if animal is threatened. However, the literature data on injuries caused by Indian crested porcupine are absent. We describe pathomorphological lesions in an Indian crested porcupine from the Ljubljana Zoo, which died after a fight with a younger male that caused a perforative quill injury of the thoracic wall, followed by septicaemia. Macroscopic, microscopic and bacteriological findings were detailed.
Original Scientific Article. Assessment of Reagent Effectiveness and Preservation Methods for Equine Faecal Samples
Authors: Vavrouchova Eva , Bodecek Stepan , Dobesova Olga 
Published: February 2015

Abstract
The aim of our study was to identify the most suitable flotation solution and effective preservation method for the examination of equine faeces samples using the FLOTAC technique. Samples from naturally infected horses were transported to the laboratory and analysed accordingly. The sample from each horse was homogenized and divided into four parts: one was frozen, another two were preserved in different reagents such as sodium acetate-acetic-acid-formalin(SAF) or 5% formalin. The last part was examined as a fresh sample in three different flotation solutions (Sheather´s solution, sodium chloride and sodium nitrate solution, all with a specific gravity 1.200). The preserved samples were examined in the period from 14 to 21 days after collection. According to our results, the sucrose solution was the most suitable flotation solution for fresh samples (small strongyle egg per gram was 706 compared to 360 in sodium chlorid and 507 in sodium nitrate) and the sodium nitrate solution was the most efficient for the preserved samples (egg per gram was 382 compared to 295 in salt solution and 305 in sucrose solution). Freezing appears to be the most effective method of sample preservation, resulting in minimal damage to fragile strongyle eggs and therefore it is the most simple and effective preservation method for the examination of large numbers of faecal samples without the necessity of examining them all within 48 hours of collection. Deep freezing as a preservation method for equine faeces samples has not, according to our knowledge, been yet published.
Investigation of pH-dependent swelling behavior and kinetic parameters of novel poly(acrylamide-co-acrylic acid) hydrogels with spirulina
Authors: Aydınoğlu Demet 
Published: February 2015

AbstractPoly(acrylamide-co-acrylic acid)-spirulina (AAm-AAc-Sp) hydrogels were prepared by free radical solution polymerization of the monomer acrylamide (AAm) and the comonomer acrylic acid (AAc) with N,N-methylene bisacrylamide (BAAm) as the crosslinker in the presence of spirulina (Sp), which is a microalga species. The swelling ratios of the hydrogels were followed by gravimetric measurements. Hence, swelling kinetics and diffusion parameters were determined. Furthermore, the morphological structures and mechanical behaviors of the hydrogels were investigated by scanning electron microscopy and by using a uniaxial compression machine, respectively. All the results showed that spirulina had strong influence in the pH-dependent swelling behavior, as well as on the kinetic and diffusion parameters due to its interaction with the acrylic acid units. These interactions were attributed to spirulina, which caused a change in pore size and its distribution. The present novel hydrogels showed high swelling at neutral pH, but collapsed slowly at low and high pH values. Thus, these AAm-AAc-Sp hydrogels can be good candidates for pH-sensitive drug delivery systems.
Examining Developmental Differences in Imagery Use with Youth Soccer Players
Authors: Gregg Melanie , Strachan Leisha 
Published: February 2015

Abstract
Emerging research on youth sport participants has revealed that young athletes use sport-related mental imagery for a variety of purposes such as acquiring sport-specific skills. The present study aimed to replicate previous research regarding developmental differences in imagery use, confirm the utility of the Sport Imagery Questionnaire-Children’s Version (SIQ-C), and clarify the relationship of gender to imagery use in youth sport. Youth soccer players (N = 207) included boys and girls ranging in age from 7 to 16 years. All participants completed the SIQ-C. Results replicated previous research indicating the SIQ-C is a suitable tool for examining imagery use by youth sport participants. Developmental differences similar to previous research were also replicated; younger age cohorts were more likely to use motivational-specific (goal-oriented) images. No gender differences in imagery use materialized; recruiting participants from a single sport allowed direct comparisons between genders and eliminated the confounding variable of sport type.

Further Results of Flat Space-time Theory of Gravitation
Authors: Petry Walter 
Published: February 2015

Abstract
The anomalous acceleration of spacecrafts in the solar system is explained. An explanation of the observed superluminal velocities of jets at extragalactic objects is given. The extension of quasars can be larger as generally assumed, i. e. quasars must not be very compact objects. An explanation of the high energy loss per unit time of quasars is given. The relation between the velocity of an object in the universe and its redshift is stated. All these results are received from cosmological models studied by flat space-time theory of gravitation and the post-Newtonian approximation of perfect fluid in these cosmological models where clocks at earlier times are going faster than at present.

The substituent effects on the geometrical parameters and the electron density are discussed.
Studies on the Local Structure of the Tetragonal Er3+ Center in CaO
Authors: Wu Shao-Yi , Dong Hui-Ning 
Published: February 2015

Abstract
The local structure of the tetragonal Er3+ center in CaO is theoretically studied by using the perturbation formulas of the g factors for a 4f11 ion in tetragonal symmetry. In these formulas, the contributions to the g factors from the second-order perturbation terms and the admixtures of various states are taken into account. Based on the investigations, this center is suggested to be the impurity Er3+ substituting the host Ca2+ site, associated with a Ca2+ vacancy VCa in the [100] (C4) axis due to charge compensation. By studying the g factors of the tetragonal center, impurity Er3+ is expected to undergo an off-center displacement ΔZ(≈ 0.2 Å ) towards the VCa along the C4 axis because of the electrostatic attraction. The calculated g factors based on the displacement ΔZ show reasonable agreement with the observed values.

Studies of the Orientational Disorder at the Isotropic to Smectic-F Interface
Authors: Padmaja S. , Rao M. Ramakrishna Nanchara , Prasad P.V. Datta , Pisipati V. G. K. M. 
Published: February 2015

Abstract
Density studies on the isotropic to smectic-F transition in higher homologues of N-(p-nalkoxybenzylidene)- p-n-decylanilines (nO.10) mesomorphic compounds with n = 13, 14 and 15 and corresponding studies on thermal expansion coefficient maxima confirm the first order nature of this transition. The density shows strong pretransitional fluctuations, which are estimated by αeff in the vicinity of the mesomorphic fluctuation dominated non-linear region (FDNLR) of this phase transition. The growth of the density fluctuations across this transition is discussed in the light of data on the same transition in other compounds.

Published: February 2015

Abstract
Single crystals of the hydrous cadmium borate Cd6B22O39·H2O were obtained through a high-pressure/high-temperature experiment at 4.7 GPa and 1000 °C using a Walker-type multianvil apparatus. CdO and partially hydrolyzed B2O3 were used as starting materials. A single crystal X-ray diffraction study has revealed that the structure of Cd6B22O39·H2O is similar to that of the type M
6B22O39·H2O (M=Fe, Co). Layers of corner-sharing BO4 groups are interconnected by BO3 groups to form channels containing the metal cations, which are six- and eight-fold coordinated by oxygen atoms. The compound crystallizes in the space group Pnma (no. 62) [R1=0.0379, wR2=0.0552 (all data)] with the unit cell dimensions a=1837.79(5), b=777.92(2), c=819.08(3) pm, and V=1171.00(6) Å3. The IR and Raman spectra reflect the structural characteristics of Cd6B22O39·H2O.

AbstractDissemination of primary tumor cells depends on migratory and invasive attributes. Here, we identify Navigator‐3 (NAV3), a gene frequently mutated or deleted in human tumors, as a regulator of epithelial migration and invasion. Following induction by growth factors, NAV3 localizes to the plus ends of microtubules and enhances their polarized growth. Accordingly, NAV3 depletion trimmed microtubule growth, prolonged growth factor signaling, prevented apoptosis and enhanced random cell migration. Mathematical modeling suggested that NAV3‐depleted cells acquire an advantage in terms of the way they explore their environment. In animal models, silencing NAV3 increased metastasis, whereas ectopic expression of the wild‐type form, unlike expression of two, relatively unstable oncogenic mutants from human tumors, inhibited metastasis. Congruently, analyses of > 2,500 breast and lung cancer patients associated low NAV3 with shorter survival. We propose that NAV3 inhibits breast cancer progression by regulating microtubule dynamics, biasing directionally persistent rather than random migration, and inhibiting locomotion of initiated cells.
A Poroelastic-Viscoelastic Limit for Modeling Brain Biomechanics
Authors: Hasan Md. Mehedi , Drapaca Corina S. 
Published: February 2015

ABSTRACTThe brain, a mixture of neural and glia cells, vasculature, and cerebrospinal fluid (CSF), is one of the most complex organs in the human body. To understand brain responses to traumatic injuries and diseases of the central nervous system it is necessary to develop accurate mathematical models and corresponding computer simulations which can predict brain biomechanics and help design better diagnostic and therapeutic protocols. So far brain tissue has been modeled as either a poroelastic mixture saturated by CSF or as a (visco)-elastic solid. However, it is not obvious which model is more appropriate when investigating brain mechanics under certain physiological and pathological conditions. In this paper we study brain’s mechanics by using a Kelvin-Voight (KV) model for a one-phase viscoelastic solid and a Kelvin-Voight-Maxwell-Biot (KVMB) model for a two-phase (solid and fluid) mixture, and explore the limit between these two models. To account for brain’s evolving microstructure, we replace in the equations of motion the classic integer order time derivatives by Caputo fractional order derivatives and thus introduce corresponding fractional KV and KVMB models. As in soil mechanics we use the displacements of the solid phase in the classic (fractional) KVMB model and respectively of the classic (fractional) KV model to define a poroelastic-viscoelastic limit. Our results show that when the CSF and brain tissue in the classic (fractional) KVMB model have similar speeds, then the model is indistinguishable from its equivalent classic (fractional) KV model.
Validity of the Free Electron Model for Two-Dimensional Electrodes
Authors: Kondo Kenji 
Published: February 2015

ABSTRACTGenerally, the electrodes are regarded as free electron gases when we calculate the transport characteristics of nanostructure materials or devices. In three dimensional electrodes, there are little electron correlation. However, in low-dimensional electrodes, electron correlation becomes much larger than that in three dimensional ones. Recently, nanotechnology has made much progress to fabricate two-dimensional (2D) electrodes easily and precisely. As a result, we must consider whether two-dimensional electrodes can be regarded as free electron gases. In this study, we investigate the electron energy spectrum of 2D electrodes, taking into consideration the electron correlation. These results suggest that the free electron model is justified only at the Fermi momentum and that we should not regard 2D electrodes as free electron gases without careful consideration under high electric field and/or high temperature.

Published: February 2015

ABSTRACTX-ray beam-induced damage in nanoscale metal islands was investigated. Monolayer-high Ni islands were prepared on a Cu(111) substrate. High brilliance X-rays with photon energies between 8.45 and 8.85 keV illuminated the sample for about 11 hours. In order to track changes in the morphology of the islands, the synchrotron X-ray scanning tunneling microscopy (SX-STM) technique was utilized. The result shows that X-ray illumination onto Ni islands does not induce noticeable damage. The study demonstrates that local beam-induced changes can be studied using SX-STM.
Mesoscale modeling of cement matrix using the concept of building block
Authors: Lau Denvid , Yu Zechuan , Buyukozturk Oral 
Published: February 2015

ABSTRACTCalcium silicate hydrate (C-S-H) gel is the cohesive phase in cement paste and critically controls the cement hydration. Atomistic models can reproduce reasonable structural and mechanical properties of C-S-H gel at the nano scale. However, the length and time scale of such all-atom modeling technique are restrained by limited computing power. Under this context, coarse-grained modeling technique emerges as a useful alternative for investigating cement paste at extended length and time scale. Here, we regard the building block of cement as ellipsoid and develop a coarse-grained model of cement matrix based on the Gay-Berne (GB) potential. Emphasis of the present paper is on the parameterization and interpretation of the GB potential formula.
Microstructures and Mechanical Properties of MoSi2 / Mo5Si3 / Mo5Si3C Ternary Eutectic Composite

Published: February 2015

ABSTRACTMicrostructures and mechanical properties of directionally solidified (DS) MoSi2 / Mo5Si3 / Mo5Si3C ternary eutectic composites were investigated. Ternary eutectic microstructure of a script-lamellar type that is characterized by rod-shaped Mo5Si3 and Mo5Si3C phases extending along the growth direction in the MoSi2 single crystalline matrix was developed simply by directional solidification at a growth rate of 10 mm/h. Compression tests along $[{\rm{1}}\mathop 1\limits^- 0]_{MoSi_2 }$ nearly parallel to the growth direction revealed that the DS ternary eutectic composites were plastically deformed above 1000 °C. Yield stresses of the DS ternary eutectic composites were much higher than those of binary composites mainly because of a smaller average thickness of MoSi2 matrix.

ABSTRACTCurrently, the research team is systematically studying the oxide compounds present in the ternary system In2O3-TiO2-MgO in order to analyze its thermoluminescent (TL) response. The oxide Mg1.5InTi0.5O4 present in this system was synthesized by a solid state reaction at 1350 °C in air. The X-ray powder diffraction pattern showed a spinel-type structure for this compound. In this work, this spinel, as well as its TL properties when exposed to beta particles, are being reported for the first time. The glow curve is simple and wide with a TL maximum located at 203 °C at 21.33 Gy. The peak shows a shift to lower temperatures and it increases its intensity, as the irradiation dose increases. The lineal behavior was observed between 10.66 to 341 Gy, and no saturation signs were observed. The relative sensitivity variation was 2.7% and standard deviation after ten consecutive irradiation - TL readout cycles was 1 %. The minimum detectable dose was 5.65 Gy for this spinel-type oxide [3]. These results suggest the possible application of Mg1.5InTi0.5O4 in dosimetry.
