Published: July 2015

Abstract
The full potential linear-muffin-tin-orbital method within the spin local density approximation has been used to study the structural, electronic, magnetic and thermodynamic properties of three multiferroic compounds of XFeO3 type. Large values of bulk modulus for these compounds have been obtained, which demonstrates their hardness. The calculated total and partial density of states of these compounds shows a complex of strong hybridized 3d and 4d states at Fermi level. The two degenerate levels eg and t2g clearly demonstrate the origin of this complex. We have also investigated the effect of pressure, from 0 GPa to 55 GPa, on the magnetic moment per atom and the exchange of magnetic energy between the ferromagnetic and antiferromagnetic states. For more detailed knowledge, we have calculated the thermodynamic properties, and determined heat capacity, Debye temperature, bulk modulus and enthropy at different temperatures and pressures for the three multiferroic compounds. This is the first predictive calculation of all these properties.

Abstract
Copper sulfide-selenide (CuS0.2Se0.8) thin films were deposited on FTO coated glass substrate (fluorine doped tin oxide) and stainless steel substrates using electrodeposition technique. Deposited thin films were characterized using different characterization techniques viz. X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis spectroscopy, photoluminescence spectroscopy and surface wettability. XRD study showed polycrystalline nature with cubic phase of the films. Scanning electron microscopy showed that the surface area of the substrate was covered by the nanoplatelets structure of a thickness of 140 to 150 nm and optical study showed that the direct band gap was ~1.90 eV. Surface wettability showed hydrophobic nature of the CuS0.2Se0.8 thin films.
Haar Wavelet Based Implementation Method of the Non–integer Order Differentiation and its Application to Signal Enhancement

Published: July 2015

Abstract
Non–integer order differentiation is changing application of traditional differentiation because it can achieve a continuous interpolation of the integer order differentiation. However, implementation of the non–integer order differentiation is much more complex than that of integer order differentiation. For this purpose, a Haar wavelet-based implementation method of non–integer order differentiation is proposed. The basic idea of the proposed method is to use the operational matrix to compute the non–integer order differentiation of a signal through expanding the signal by the Haar wavelets and constructing Haar wavelet operational matrix of the non–integer order differentiation. The effectiveness of the proposed method was verified by comparison of theoretical results and those obtained by another non–integer order differential filtering method. Finally, non–integer order differentiation was applied to enhance signal.

Published: July 2015

Abstract
The problem of small bit error rate is actual in fiber Raman amplifiers. Our experimental data on the amplified spontaneous emission (ASE) with backward pumping as a base of optical noise evaluation are presented in this paper. Raman gain spectrum for useful Stokes low-powered signal is calculated and compared with obtained spectrum of non-coherent ASE noise. It is shown that output optical signal has better gain than the amplified spontaneous emission that leads to appreciable growth of output optical signal-to-noise ratio.
Independence Between Two Channels of Surface Electromyogram Signal to Measure the Loss of Motor Units
Authors: Arjunan Sridhar P. , Kumar Dinesh , Naik Ganesh 
Published: July 2015

Abstract
This study has investigated the relationship in the connectivity of motor units in surface electromyogram (sEMG) of biceps brachii muscle. It is hypothesized that with ageing, there is reduction/loss in number of motor units, leading to reduction in the independence between the channels of the recorded muscle activity. Two channels of sEMG were recorded during three levels of isometric muscle contraction: 50 %, 75 % and 100 % maximal voluntary contraction (MVC). 73 subjects (age range 20-70) participated in the experiments. The independence in channel index (ICI) between the two sEMG recording locations was computed using the independent components and Frobenius norm. ANOVA Statistical analysis was performed to test the effect of age (loss of motor units) and level of contraction on ICI. The results show that the ICI among the older cohort was significantly lower compared with the younger adults. This research study has shown that the reduction in number of motor units is reflected by the reduction in the ICI of the sEMG signal.
Game localisation as software-mediated cultural experience: Shedding light on the changing role of translation in intercultural communication in the digital age
Authors: O’Hagan Minako 
Published: July 2015

AbstractIn this rapidly technologising age translation practice has been undergoing formidable changes with the implication that there is a need to expand the disciplinary scope of translation studies. Taking the case of game localisation this article problematises the role of translation as intercultural communication by focusing on cultural elements of video games. Game localisation evolved in response to the game industry’s need to distribute game software in territories other than the country of origin whereby adjusting games technically, linguistically and culturally to suit the requirements of the target market. Despite the importance of this cross-lingual and cross-cultural operation for the industry’s success in the global market, game localisation remains an underreported area of research in translation studies. A critical analysis of game localisation as generating software-mediated cultural experiences reveals intercultural communication issues due to the nature of modern digital games as technological and cultural artefacts. By combining translation studies perspectives and the theoretical framework of critical theory of technology, the author argues that game localisation is eliciting something new about the role of translation in forging intercultural communication in the digital age.
Teaching the Romanian neighbors Hungarian: language ideologies and the Debrecen Summer School
Authors: Kiss Attila Gyula 
Published: July 2015

AbstractThis article is a contribution to the hitherto scant literature on learning a historical minority language and on language ideologies in the context of a study abroad program in Hungary, Debrecen. I analyse the language ideologies of the decision makers in Hungary and in the Debrecen Summer School in relation to the teaching of Hungarian to the neighboring peoples. Drawing on interactional data of participants from Romania, the perspective of learning Hungarian as a historical minority language is examined. The present article combines a historical approach with language ideologies by focusing on an institution offering language education. Language ideologies are presented as they appear in the larger historical discourses, contemporary documents, and media interviews. I briefly outline the major turning points in the history of the institution which also reflects the changing language ideologies and cultural politics of Hungary. The qualitative discourse analysis of interviews and the conclusion of this ethnographic study demonstrate that language ideological positions in relation to the teaching and learning of Hungarian have been firmly located in historical and cultural contexts. Discourse analysis of various data demonstrates that, on the one hand, the course providers have espoused competing ideologies of who the learners should be as well as how to present the country and the culture, while, on the other hand, showing that the learners have had to negotiate prejudice and stereotype rooted in discourses about the often burdened history.
Indium-Tin-Oxide for High-performance Electro-optic Modulation
Authors: Ma Zhizhen , Li Zhuoran , Liu Ke , Ye Chenran , Sorger Volker J. 
Published: July 2015

Abstract:Advances in opto-electronics are often led by discovery and development of
materials featuring unique properties. Recently, the material class of
transparent conductive oxides (TCO) has attracted attention for active photonic
devices on-chip. In particular, indium tin oxide (ITO) is found to have
refractive index changes on the order of unity. This property makes it possible
to achieve electrooptic modulation of sub-wavelength device scales, when thin
ITO films are interfaced with optical light confinement techniques such as found
in plasmonics; optical modes are compressed to nanometer scale to create strong
light-matter interactions. Here we review efforts towards utilizing this novel
material for high performance and ultra-compact modulation. While high
performance metrics are achieved experimentally, there are open questions
pertaining to the permittivity modulation mechanism of ITO. Finally, we review a
variety of optical and electrical properties of ITO for different processing
conditions, and show that ITO-based plasmonic electro-optic modulators have the
potential to significantly outperform diffractionlimited devices.

The Experience of Dual Career through Slovak Athletes’ Eyes
Authors: Geraniosova Kristina , Ronkainen Noora 
Published: July 2015

Abstract
The purpose of this study was to examine how Slovak athletes experience dual career (the combination of an athletic career with education and/or work). The study strived to gain an understanding of the athletes’ attitudes towards education as well as perceived difficulties and supporting elements in pursuing dual career. Five athletes were interviewed once for approx. 105 min. The interviews and data analysis were based on Intepretative Phenomenological Analysis (IPA) and the interviews were focused on their experience in combining an athletic career with education or work. The athletes experienced dual career as manageable as long as they were assisted by at least simple supportive structures and provided flexible arrangements. Peers had played an important role in athletes’ decision-making concerning dual career and in providing social support when facing challenges within dual career. The teachers’ prejudice against the athletes based on their athletic role and the lack of dual career structures appeared to be significant deficiencies in dual career support. Finally, the analysis revealed the negative perception of athletes and sport science students by educational representatives. This perception may be a hurdle to be overcome in future dual career development.
Health Status of Healthcare Professionals Working in an Institute for Chronically Ill Psychiatric Patients
Authors: Nagyváradi Katalin , Mátrai Zsuzsa 
Published: July 2015

Abstract
Several research works in the related international literature on sociology and health sciences deal with the state of health in one selected population. In these studies, the chosen sample is often connected with special jobs, especially with healthcare professionals and their working conditions. These studies predominantly examine the self-rated subjective health status using questionnaires. There are others that assess the state of health based not only on self-rated subjective indicators, but also using objective data gained by measuring. Considering the international experiences, we chose a special population in our research – healthcare professionals working in an institute for chronically ill psychiatric patients. Our choice was influenced by the fact that we wanted to include their unique working conditions when exploring and assessing their health status. Moreover, our approach was to assess the objective state of health alongside the subjective factors, as our hypothesis was that the majority of the indicators presumably coincided. The data were collected with the help of three questionnaires and some indicators of the objective health statuses were measured. The findings were processed using the SPSS 17.0 mathematical-statistical software package. Following the descriptive statistics, we applied hierarchic cluster-analysis based on results of the WHOQOLD-BREF26 life-quality questionnaire, the WHO WBI-5 Well Being Index, and on the body composition analysis. The results show the objective and subjective health status of population and the factors that influenced it; the working conditions and the interpersonal contacts in the workplace. The conclusion was that in the examined population the subjective and objective health status doesn’t coincide.

Published: July 2015

Abstract
The uneven spatial distribution of basic facilities within urban areas is a major problem for developing countries like Senegal due to the emphasis of accessibility disparities and the use of this services. The efforts to quantify the problem and its consequences on people are constrained by the lack of satisfactory data and methods. The study seeks to examine the spatial accessibility to basic services (access to water, health, education, economic infrastructure and transportation services) in a very heterogeneous urban system and to highlight inequalities in access for improving the geographical accessibility and to ensure equity. The article explore the use of spatial analysis method (Closest Facility) to measure the potential accessibility to services and facilities in the city of Mbour. The analyses uses all the inhabited houses of the city as the potential demand. Results emphasis unequal access to basic urban services in the city and a center-periphery model with a high concentration of services around the city. The study demonstrates the utility of this method for the identification of disadvantaged areas, decision making and planning of basic services. It also provides paths for improving accessibility in urban areas with a high density of population.

Authors: Alam Mahbub , Bahauddin Khalid Md. 
Published: July 2015

Abstract
Electronic waste (e-waste) is one of the fastest-growing pollution problems worldwide given the presence if a variety of toxic substances which can contaminate the environment and threaten human health, if disposal protocols are not meticulously managed. In Bangladesh almost 2.7 million metric tons of e-waste generated per year. Of this amount only 20 to 30 percent is recycled and the rest of the waste is released in to landfills, rivers, drains lakes, canals, open spaces which are very hazardous for the health and environment. Since Bangladesh is in the stream of rapid technological advancement, it is seldom to take necessary steps to avoid the future jeopardized situation because of e-waste. The current practices of e-waste management in Bangladesh suffer from a number of drawbacks like the difficulty in inventorisation, unhealthy conditions of informal recycling, inadequate legislation and policy, poor awareness and reluctance on part of the corporate to address the critical issues. The paper highlights the associated issues and strategies to address this emerging problem, analyses the policy and its gaps. Therefore, this paper also suggest that e-waste policy development may require a more customized approach where, instead of addressing e-waste in isolation, it should be addressed as part of the national development agenda that integrates green economy assessment and strategic environmental assessment as part of national policy planning. Finally this work also suggests some alternative strategies and approaches to overcome the challenges of e-waste.

Thereports evaluating the impact of obesity on the obtained pathologic response to chemotherapy are unequal.was to evaluate in locally advanced breast cancer patients, treated with AT(doxorubicin plus docetaxel) neoadjuvant chemotherapy: 1. The relationship of obesity with obtaining pathological response. 2. The relationship of obesity and free of disease recurrence survival (DFS) and overall survival (OS) associated with the tumour.A retrospective study was carried out in a group of 105 patients with locally advanced breast cancer, treated with AT neoadjuvant chemotherapy and then treated with radical surgery. Two variants of pathological response have been adopted: a pCR (T0N0) and pCR1 (TisN0, TxN1, T1N0, T1N1, T0N1). The relationship of obesity with pathological response and survival was investigated.In univariate analysis the pCR1 was obtained with its arising from the borderline of statistical significance with lower incidence of obesity. In pCR1 multivariate analysis, negative pCR1 relationship with obesity was on the borderline of the statistical significance. The multivariate analysis showed a significant negative association OS with obesity (p=0.047) and positive with the occurrence of menopause (p = 0.029).In patients with locally advanced breast cancer treated with AT neoadjuvant chemotherapy. 1. Obesity seems to be an independent and unfavourable predictor of the lack of obtaining pCR1 pathological response 2. In the multivariate analysis, the obesity was a significant independent factor related to shorter OS.

Published: July 2015

Abstract
The study aimed at immunohistochemical analysis of various markers of cell proliferation and comparison of the results with canine mast cell tumours grading systems according to the Patnaik and Kiupel. Tissue sections were stained using classical technique with haematoxylin and eosin, and immunohistochemical studies were performed with Ki-67, PCNA and MCM-3 antibodies. Additionally the mitotic index was assessed. Statistical analysis including rank correlation Spearman’s and ANOVA Friedman analysis was performed. The significance was set at p<0.05. Expression of all examined antigens was detected. The results obtained allow concluding that there is a strong relationship between all the cell markers. However, due to the very strong response and positive reaction in the majority of tumours PCNA is not recommended as a prognostic indicator. Ki-67 and MCM-3 can be successfully used in the evaluation of canine mast cell tumours.

Published: July 2015

Abstract
The aim of this study was to compare physiological responses in Siberian sturgeon (Acipenser baeri) induced by propofol and CO2 anaesthesia. Two procedures were applied during the experiment. In procedure I, blood samples were collected immediately after exposure (1, 2, 5, 10 min) to the anaesthetic. In procedure II, fish were exposed to the anaesthetic for 10 minutes and then were moved to anaesthetic free water. Blood was sampled after 5, 10, 20 or 30 min of recovery time. Gasometrical and biochemical analyses were performed on collected blood.
In CO2 anaesthetized fish strong hypercapnic acidosis was revealed. The drop of the HCO3−/CO2 ratio, from 28:1 in control fish up to 4:1 in CO2 anaesthetized ones, proved that the compensation mechanism is not capable of preventing acidosis during CO2 anaesthesia in Siberian sturgeon. In contrast, only moderate, respiratory acidosis occurred in sturgeons anaesthetised with propofol. Hypercapnic acidosis during CO2 anaesthesia was followed by a fourfold increase of ammonia level in the blood. Glucose level, increasing only during recovery time, indicates that a secondary stress response occurred when awareness of anaesthetized fish had been restored.
