Low Emissions Combustor Development for an Industrial Gas Turbine to Utilise LCV Fuel Gas
Authors: Kelsall G. J. , Smith M. A. , Cannon M. F. 
Published: February 2015

Advanced coal based power generation systems such as the British Coal Topping Cycle offer the potential for high efficiency electricity generation with minimum environmental impact. An important component of the Topping Cycle programme is the gas turbine, for which development of a combustion system to burn low calorific value coal derived fuel gas, at a turbine inlet temperature of 1260°C (2300 F), with minimum pollutant emissions, is a key R&D issue.
A phased combustor development programme is underway burning low calorific value fuel gas (3.6–4.1 MJ/m3) with low emissions, particularly NOx derived from fuel bound nitrogen.
The first phase of the combustor development programme has now been completed using a generic tubo-annular, prototype combustor design. Tests were carried out at combustor loading and mach numbers considerably greater than the initial design values. Combustor performance at these conditions was encouraging.
The second phase of the programme is currently in progress. This will assess, initially, an improved variant of the prototype combustor operating at conditions selected to represent a particular medium sized industrial gas turbine. This combustor will also be capable of operating using natural gas as an auxiliary fuel, to suit the start-up procedure for the Topping Cycle.
The paper presents the Phase 1 test programme results for the prototype combustor. Design of the modified combustor for Phase 2 of the development programme is discussed, together with preliminary combustion performance results.
Experimental Investigation of the Steady and Unsteady Relative Flow in a Model Centrifugal Impeller Passage
Authors: Abramian M. , Howard J. H. G. 
Published: February 2015

The behaviour of the relative flow in centrifugal turbomachines is extremely complex due to the existence of various fluid dynamic phenomena and their interaction. At design and off-design operating conditions, the relative flow is subject to stationary unsteadiness which includes flow separation and wakes associated with passage pressure gradients, secondary flows, and boundary layer stability. It may also be subject to periodic unsteadiness such as is the rotating stall and cyclic flow phenomena induced by the casing.
This paper describes detailed measurements of the relative velocity field in a very low specific speed centrifugal pump impeller (Ns=515). Measurements were conducted by means of a recently developed rotating laser-Doppler anemometry system. Detailed quantitative description of the mean and fluctuating components of the primary and secondary velocity fields are presented for an impeller without volute at design, 50% design and shut-off conditions. The flow pattern in this low specific speed impeller with high blade loading is dominated by the relative eddy (a phenomenon also present in potential flow) which has suppressed suction side separation. When the impeller was fitted with a volute, the cyclic variation of the impeller exit flow, induced by the volute at low flow rates, is also presented.
A Country That Does Not Exist
Authors: Largo Marissa 
Published: February 2015

This paper examines the 2013 exhibition Through the Looking Glass: Inside My Domestic Portrait of Filipino Canadian artist Julius Poncelet Manapul. I ask in this case study: What are the ways in which Filipino Canadian artists mobilize art in response to their invisibility in Canadian society? Adopting a contextual analysis, I interpret Manapul’s artwork, my interview with the artist, and his writings and place them in conversation with discourses of contemporary art, visual culture, and cultural studies.
I argue Manapul’s hybrid art practice represents an emerging queer decolonial aesthetic that challenges Western heteronormative standards of family, home, identity, and citizenship consequently creating a utopic, third space of potentiality. Through physical, symbolic, and virtual interventions, Manapul provides an alternative vision of postcolonial subjectivity, which defies essentialist readings of ethnic identity prevalent in Canada’s neoliberal multicultural discourse. I discuss the implications of Manapul’s queer decolonial aesthetic in relation to multiculturalism in Canada and its generative possibilities for contemporary queer theory.
Does sex influence the incidence or severity of reperfusion-induced cardiac arrhythmias?
Authors: Dow Joan S , Bhandari Anil , Hale Sharon L , Kloner Robert A 
Published: February 2015

AbstractWhether sex affects the acute phase of myocardial ischemia in experimental animal models is currently being debated. Our purpose was to determine if sex influences either the incidence or severity of reperfusion-induced arrhythmias resulting from a brief coronary occlusion. Male and female Sprague–Dawley rats were assigned to the study. Anesthetized animals were subjected to a 5-minute coronary artery occlusion followed by 5 minutes of reperfusion. Mortality differed by sex: 10/27 (37%) of males died due to VT/VF while only 1/16 females (6%) died due to VT/VF (p = 0.033). Quantitative analysis of the electrocardiogram was performed on data acquired from 17 male and 15 female survivors. Analysis showed no other significant differences in ventricular arrhythmias between the two groups. Conclusion: Lethal reperfusion-induced arrhythmias led to a higher mortality in male rats versus female rats. Among survivors there was no difference in any other arrhythmic parameters measured.
EMT and tumor metastasis

Published: February 2015

AbstractEMT and MET comprise the processes by which cells transit between epithelial and mesenchymal states, and they play integral roles in both normal development and cancer metastasis. This article reviews these processes and the molecular pathways that contribute to them. First, we compare embryogenesis and development with cancer metastasis. We then discuss the signaling pathways and the differential expression and down‐regulation of receptors in both tumor cells and stromal cells, which play a role in EMT and metastasis. We further delve into the clinical implications of EMT and MET in several types of tumors, and lastly, we discuss the role of epigenetic events that regulate EMT/MET processes. We hypothesize that reversible epigenetic events regulate both EMT and MET, and thus, also regulate the development of different types of metastatic cancers.
Living with advanced-stage Huntington's disease: an exploration of the experiences of Maltese family caregivers
Authors: Scerri Rosanne 
Published: February 2015

Aim: The aims of this study were to explore the experiences of Maltese family caregivers (FCs) caring for individuals with advanced-stage Huntington's disease (HD) and to integrate findings using grounded theory principles. Method: Data collection and analysis were based on grounded theory principles. Eight in-depth semi-structured interviews were carried out with carers of individuals who were living at home or in an institution. The software programme MAXQDA was used to assist with analysis. Results: The results of this study indicate that the experiences of HD FCs centred around the psychological impact of their caregiving experience. The interrelationship between the different categories and sub-categories is suggested using an integrative diagram. Conclusions: This study can be considered as a robust pilot study which has integrated different aspects of the caregiver's experiences. Practical and policy implications centre on the need to develop measures to support FCs. Future research aimed at developing a theoretical framework is warranted.
Multiple sclerosis and disease modifying therapies: results of two UK surveys on factors influencing choice
Authors: Colhoun Samantha , Wilkinson Carmel , Izat Alan , White Sarah , Pull Emily , Roberts Megan 
Published: February 2015

Background: Multiple sclerosis (MS) is a disease of the central nervous system. There is no cure for MS but there are treatments available which reduce the severity, frequency and duration of relapses, known as disease modifying therapies (DMTs). Aim: The objective of the study was to gain insight into the factors influencing choice of DMT when starting or switching therapy. Methodology: Two separate surveys of MS nurses and people with MS taking a DMT were designed by a group of MS nurses; they were funded and supported by Novartis Pharmaceuticals UK Ltd and implemented in 2014. Results: Patients clearly stated that while highly valuing their MS nurse and neurologist, they wanted more clarity around the effectiveness, side effects and risks of DMTs. Some 84% of patients wanted to be part of the decision-making process regarding their treatment. Conclusion: Shared decision making underpins effective disease management and is particularly important in relation to DMT prescribing. The importance of the MS nurse role in providing patients with individually tailored information is supported by the results of this survey.
Perinatal death: bereavement interventions used by US and Spanish nurses and midwives
Authors: Steen Sue E 
Published: February 2015

Background: Little research has been published from a global perspective regarding needs of nurses and midwives related to perinatal bereavement. Objective: To identify needs and concerns of US and Spanish nurses and midwives who have worked with perinatal death and to identify the bereavement interventions they use to help families with this experience. Methods: A cross-sectional study was conducted. Data were collected in 2011 from US (n=44) and Spanish (n=15) nurses and midwives via a questionnaire. Results: Statistically significant differences between the nurses/midwives in each country were found regarding needs relating to knowledge, communication skills and managing personal feelings. Interventions of accompanying, listening, offering keepsakes, baptism discussion, and funeral planning were also found to be significantly different between the two groups. Conclusions: These findings demonstrate a continued need to increase the standard and consistency of perinatal bereavement care worldwide. Bereavement education in nursing curricula and practice settings in both cultures is essential to increase the standard of care.

Published: February 2015

Objective: To study effectiveness of innovative method of anaesthesia for eye surgeries in paediatric age group.
Methods: This is a retrospective study. We retrieved data from Medical Record Department for all children (0 to 18) who had undergone ocular surgeries between January 2008 to December 2013 at tertiary eye care centre. Sedation along with regional anaesthesia (topical or peribulbar block) or general anaesthesia was the preferred mode of anaesthesia under which cataract, strabismus, lacrimal, ocular trauma and retinal surgeries were performed. All surgeries, methods, medicines and complications of anaesthesia were properly documented.
Results: In all, 1941 cases were operated. Among them 1084 were males and 857 were females; 520 were cataract surgeries, 723 were strabismus surgeries, 285 were lacrimal surgeries, 185 were ocular trauma and 228 were retinal surgeries. Median age of patients was 8+/-4.8 (0 to 17). All surgeries were eventless and no serious perioperative complication was encountered.
Conclusion: Combination of sedation and regional anaesthesia is a good cost effective method for ocular anaesthesia in children for eye surgeries.

Published: February 2015

Abstract
This study explored the prevalence of posttraumatic symptomatology (PTS) and functional problems among Israeli individuals with intellectual disability (ID) who live in supported residential care settings and who have been exposed to political violence. The sample included 196 residents exposed to chronic missile attacks and 91 residents with ID who were not exposed. Results showed PTS and functional problems to be higher in the exposed group compared to the nonexposed one, although still low compared to the general exposed population. Exposure was found to be related to PTS and functioning problems suggested individuals with ID are reactive to political violence, though the underlying mechanisms are not clear. Implications for research, caretakers, and policy are discussed.
The soul gets typecast: The reincarnation film in popular Hindi cinema
Authors: Wright Neelam Sidhar 
Published: February 2015

Abstract
This article introduces the reincarnation film as an (unacknowledged) Indian film genre. After a brief historical overview of the reincarnation film, the genre’s conventions are explored through an analysis of select films – particularly Neel Kamal (1968) by Ram Maheshwari and Om Shanti Om (2007) by Farah Khan. Rather than applying a psychoanalytical approach (which would suggests that these films are primarily concerned with sexual trauma and surfacing repressed desires), I observe how reincarnation philosophy informs the style and form of these texts to address Hindu anxieties about rebirth. Reincarnation narratives are not simply a by-product of the western Gothic, but informed by and best understood in relation to ancient Indic cultural practices. Furthermore, Hindu cultural consciousness conflicts with key psychoanalytical concepts of death and the past. This research addresses the cultural specificity of film genre. It demonstrates how religious philosophy can be used to investigate film aesthetics as an alternative to the common-practice application of western psychoanalysis.

A Real Human Being and a Real Hero: Stylistic excess, dead time and intensified continuity in Nicolas Winding Refn’s Drive
Authors: Rogers Anna Backman , Kiss Miklós 
Published: February 2015

Abstract
This article sets forth that Nicolas Winding Refn’s Drive (2011) exhibits a ‘complex transformation’ of an American film genre by foregrounding features associated with art cinema and, more specifically, European and auteur film-making. We argue that the film’s appeal derives precisely from an intelligent and cine-literate deployment of the tensions in this dichotomy of European/American film-making. As such, Drive is a film that foregrounds or reveals its own construction in a number of ways, but its appeal lies in the fact that it does not prevent intense emotional engagement on the part of the viewer. It is neither a cold exercise in mere style nor a simple copy of an earlier formula, but rather a film that manages to marry a number of narrative and stylistic features in such a way that the film itself, arguably, is not easy to categorize.
Game over? The (re)play of horror in Michael Haneke’s Funny Games U.S.
Authors: Messier Vartan 
Published: February 2015

Abstract
Michael Haneke’s Funny Games U.S. (2007) is a meticulously faithful American remake of his European horror film of the same name, Funny Games (1997), which depicts the plight of a bourgeois family terrorized by two young men at their lakeside property. The purpose of this paper is twofold. First, it demonstrates how the film’s aesthetics of terror produces affective responses that undermine the characteristic emphasis on cathartic violence of the horror genre. Second, it addresses how the remake’s fidelity to the original prompts us to consider the transnational properties of representational violence. Retracing the psychoanalytic underpinnings of the ‘family in peril’ sub-genre of horror cinema, I first argue that Funny Games U.S. unsettles the viewer’s expectations by simultaneously exploiting and subverting generic conventions. Rather than resorting to spectacles of blood and gore, the film utilizes the affective potentialities of duration and self-reflexivity to rattle the audience and critique the viewing pleasure associated with representational violence. Next, I examine cinematic remakes as indicators of cultural variation, arguing that the minute differences of setting and characters between the original and the remake only aim to reinforce their similarities. In thus rendering the viewing experience almost identical, as mirroring and serial works, the films recast our understanding of the cultural specificity of spectatorship.

Effect of V/III ratio on the growth of hexagonal boron nitride by MOCVD
Authors: Paduano Qing S. , Snure Michael , Shoaf Jodie 
Published: February 2015

ABSTRACTIn this report, we describe a process for achieving atomically smooth, few-layer thick, hexagonal boron nitride (h-BN) films on sapphire substrates by MOCVD, using Triethylboron (TEB) and NH3 as precursors. Two different growth modes have been observed depending on the V/III ratio. Three-dimensional (3D) island growth is dominant in the low V/III range; in this range growth rate decreases with increasing deposition temperature. This island growth mode transitions to a self-terminating growth mode when V/III > 2000, over the entire deposition temperature range studied (i.e. 1000-1080oC). Raman spectroscopy verifies the h-BN phase of these films, and atomic force microscopy measurements confirm that the surfaces are smooth and continuous, even over atomic steps on the surface of the substrate. Using X-ray reflectance measurements, the thickness of each film grown under a range of conditions and times was determined to consistently terminate at 1.6nm, with a variation of less than 0.2 nm. Thus we have identified a self-terminating growth mode that enables robust synthesis of h-BN with highly uniform and reliable thickness on non-metal catalyzed substrates. Furthermore, this self-terminating growth behavior has shown signs of transitioning to continuous growth as deposition temperature increases.

ABSTRACTWe report on our recent progress in the study of single Dibenzoterrylene (DBT) molecules as single photon sources and nanoscale probes. We consider DBT molecules embedded in thin anthracene films, a system that allows stable single photon emission both at room and at cryogenic temperatures. We investigate the most important optical properties of the DBT:anthracene system as a whole. We then perform a full statistical study of the coupling between single DBT molecules by measuring the lifetimes of DBT both in the coupled and in the uncoupled case. The experimental results are framed into a simple universal scaling model, where the magnitude of coupling depends solely on universal parameters and on the distance d between the single emitter and the graphene monolayer. We apply this model to infer d and provide a proof of principle for a position ruler at the nanoscale [1].
First-principles study of point defects in cerium dioxide and comparison to uranium dioxide
Authors: Shi Lei , Vathonne Emerson , Freyss Michel , Bertolus Marjorie , Oison Vincent , Hayn Roland 
Published: February 2015

ABSTRACTUranium dioxide, as the standard nuclear fuel in pressurized water reactors, motivates intensive research to get further insight into the link between radiation damage and microstructure evolution of the material. Cerium dioxide is often considered as a non-radioactive model material for uranium dioxide, for which the experimental study of radiation damage could be performed more easily. Using first-principles calculations based on the density functional theory (DFT) and its DFT+U variant, we compare these two oxides in terms of point defect formation.
Modeling of the Amorphous Phase of Poly-CO with He and N
Authors: Batyrev Iskander G 
Published: February 2015

ABSTRACTDensity functional theory (DFT) and variational density functional perturbation theory (DFPT) simulations of amorphous poly-CO structures were performed to understand the stability of the polymerized structure at low pressures and to study the mechanism of destruction of the extended network at low pressures. Charge population analyses accompanied the search of the “weakest link” in the covalently bonded network. IR and Raman spectra of amorphous p-CO, calculated at 15 and 5.02 GPa, show significant contributions of CO molecules, carbonyl groups fragments decorating chains, and lactones of amorphous p-CO structures. DFT simulations of formation of amorphous polymeric structures were also done with the addition (as a result of replacement of CO molecules) of N or He atoms to the crystalline delta phase of CO. For the CO-N mixtures, the concentration of N was varied in the range from 6.25 % to 50% with different distribution patterns of N atoms in the unit cell. For all studied CO-N concentrations, isotropic compression led to CO polymerization beginning at a pressure of 11 GPa; the N was incorporated in the random network in low concentration. In CO-He mixtures He atoms appear to facilitate complete formation of the random structure which is almost completely polymerized at a pressure of 18 GPa. He atoms also help stabilize the structure at low pressures.
