Published: May 2015

Korábbi kutatások megmutatták, hogy versengő helyzetben a nagyobb jutalom megnövekedett fiziológiai arousallal jár. Mégis kevés tanulmány érintette a jutalmazás hatását a tesztoszteron (T) szintre, annak ellenére, hogy ez a hormon érzékenyen reagál a versengő helyzetekre és státuszváltozásokra. A jelen kutatás versengő helyzetben vizsgálta a nyáltesztoszteron és fiziológiai arousal (szívritmus, szívritmusvariabilitás) változásait fiatal felnőtt férfi mintán (N = 40, átlag életkor = 21.7 ± 2.3 év). A résztvev ők egy videojátékban versengtek egymással, ahol a páros egyik tagja nyert, a másik veszített a képességeknek és erőfeszítésnek megfelelően. A párosok véletlenszerű csoportosítása alapján résztvevők vagy egyenlő pénzjutalmat kaptak, vagy a győztes több jutalmat kapott, mint a vesztes (egyenlőtlen jutalom). A pszichofiziológiai és endokrinológiai méréseken túl a résztvevők versengéssel kapcsolatos attitűdjeit (hiperversengés, önfejlesztő versengés) és a versengő helyzetben mutatott hangulati változásait is felmértük kérdőívek segítségével. Az eredmények azt mutatták, hogy a versengés mindkét csoportban növelte mind a szubjektív, mind a fiziológiai arousalszintjét, ám a jutalom mértéke nem volt szignifikáns hatással a T szintre. A T szint csak a vesztes hiperversengőkben növekedett szignifikánsan. A kompetitív teljesítmény korrelált a győztesek és vesztesek T szintjével, illetve annak változásával, alátámasztva azt a korábbi megfigyelést, hogy a versengő teljesítmény és a T egymást kölcsönösen meghatározó kapcsolatban állnak. A kapott eredmények összefüggésben vannak a státuszinstabilitás-hipotézissel.
Laboratory and commercial-scale evaluation of the effect of pure and commercial endoxylanases and endoglucanases on wheat flour bread quality
Authors: Roets C. , Rose S.H. , Muller M. , Manley M.
Published: May 2015

The effect of a pure endoxylanase (Xyn2) and endoglucanase (EgII) from Trichoderma reesei on bread flour quality were compared to a commercial endoxylanase from Aspergillus niger (Com-xyl) and a cellulase-xylanase cocktail from T. reesei (Cel-xyl). Effects of these enzymes on dough quality, bread weight, height and crumb softness were analysed. Results obtained during commercial-scale baking tests often differed from those obtained during laboratory-scale tests; indicating that results from laboratory-scale baking tests cannot be extrapolated to commercialscale bread production. Low levels of endoxylanase activity benefited bread height and volume without affecting slice brightness in commercial-scale tests. The addition of endoglucanases and α-amylases can also be advantageous resulting in less endoxylanase activity required to obtain similar results.
Assessment of the antioxidant properties of tomato extracts: A synergistic approach using in vitro chemical tests and cell-based assays
Authors: García-Alonso F.J. , Navarro-González I. , Ros G. , Periago M.J.
Published: May 2015

The aim of this research was to assess the total antioxidant activity (TAA) of lipophilic (Lextr) and hydrophilic (Hextr) tomato extracts using in vitro chemical tests and cell-based assays, focusing on possible synergistic actions between tomato antioxidants. Both Hextr and Lextr were HPLC analysed for their carotenoids, phenolic compounds, and ascorbic acid contents. For the evaluation of TAA, extracts were assayed alone or in combination using in vitro chemical tests (TEAC, FRAP) and cell-based (CAA) assays using human hepatoma (HepG2) and human histiocytic lymphoma (U937) cells. The only carotenoid detected in Lextr was lycopene, while a mixture of phenolic compounds (chlorogenic acid, caffeic acid, and rutin) was identified in Hextr. Ascorbic acid was not found either in Hextr or in Lextr. Upon extract combination (1:1, v/v), the FRAP assay revealed additive action between Lextr and Hextr, whilst a slight synergistic action was observed in TAA as measured by the TEAC assay. Synergistic action was better revealed when TAA was analysed using either U937 or HepG2 cells. This could be explained by the presence of a multiphase media (cell membrane and extra- and intracellular media) that might facilitate the distribution and interaction of antioxidants with different polarities and different mechanisms of action.

Authors: Kuznik Anna , Hurtado Albir Amparo
Published: May 2015

The aim of this article is to demonstrate how the achievements of the behavioural approach to competences may enhance the study of translation competence. The first section sets out the basic premises of the behavioural approach to studying competences in the workplace from its US origins in the field of work psychology to its present application in human resources management. The second section describes four translation studies which fall within the behavioural approach to studying competences: a competence model proposal for identifying good translators; two surveys carried out with the aim to draw up competence repertoires according to professional profiles of translators and interpreters; and a study of translator competence in a business context. The article concludes with a discussion on the minor impact of behavioural studies in Translation Studies; proposes that behavioural studies should be developed further marking out possible lines of research; underlines the complementary nature of behavioural and cognitive studies applied to research into translation competence; stresses the need to describe professional profiles with an eye to optimising translator training and, finally, draws up development perspectives of behavioural studies in our field.

Published: May 2015

Citri Grandis Exocarpium (CGE) is a traditional Chinese medicine with a variety of biological activities. For efficient quality control of CGE, a simple, rapid, and accurate high-performance liquid chromatographic (HPLC) method was developed for simultaneous determination of four main compounds (naringin, rhoifolin, meranzin hydrate, and isoimperatorin) in this herb. These four compounds were separated on a C18 column by gradient elution with methanol and water. The flow rate was 1.0 mL·min−1, and the detection wavelength was 324 nm. The recoveries of the method ranged from 96.32% to 103.71%, and good linear relationships (r2 > 0.9998) over relative wide concentration ranges were obtained. Then this validated method was successfully applied to the analysis of nine batches of CGE samples.

The aim of this paper was to create a comprehensive literature review on forensic dental methods. This literature review is based on historical and the latest results of the forensic odontology. Thus, this comparative study deals with various methods including certain dental identification methods which are easy to use and do not require advanced technological background. Nowadays, the main reasons for the use of forensic odontology methods are natural disasters, however, their sensitivity depends on the availability of proper dental documentation of the subject/victim. Custom made prostheses offer the most accurate dental identification, which can allow an identification rate of 99.9%. Combination of different methods can also exhibit a high sensitivity (40–99.9%). It seems important that separation of old and novel methods is not recommended. Also, it is important to maintain and upgrade present methods which are capable of identifying one or more subjects/victims in practice. The authors propose several methods which could serve as a base of the new national policy in forensic dental identification and could be used by teams dealing with the identification of disaster victims.

Introduction: Psychological and lifestyle factors affect the development and outcome of heart disease considerably. Aim: The aims of the authors were to examine health control, level of anxiety and depression and to analyse their relationship with health behaviour in patients with ischemic heart disease. Method: The present cross-sectional study involved 116 patients who took part in residential cardiac rehabilitation (56.9% men, mean age: 57.65±8.22 years). Results: 30.9% of the patients reported elevated anxiety and 21.9% increased depressive symptomatology. Social-external control belief was the strongest among respondents. Further, anxiety and depression were negatively associated with healthy diet and the frequency of exercise. Patients with stronger social-external control beliefs were more likely to seek medical attention if they suspected a disease. Conclusions: It is important to assess psychological risk factors linked to cardiovascular diseases in cardiac rehabilitation departments and to initiate psychological interventions if indicated.

A hepatitis C patológiája
Authors: Schaff Zsuzsa , Gógl Alíz , Dóra Réka , Halász Tünde
Published: May 2015

The hepatitis C virus is an RNA virus, which belongs to the genus Hepaciviruses of the family Flaviviridae. Chronic hepatitis, cirrhosis, and ultimately even liver cancer may develop in over 80% of infected cases. The histological features of hepatitis C and hepatitis caused by other hepatotropic viruses show many similarities, however, certain specific histological characteristics are observable. Accordingly, intense lymphocytic infiltration around the periportal areas, steatosis and biliary alterations are frequent findings. Further characteristics of hepatitis C include liver cell destruction (apoptosis, necrosis), periportal inflammation and fibrosis, the degrees of which can be determined by means of the histology activity index. Our knowledge on the hepatitis C virus genome and the mechanism of replication of the virus have established the use of modern, direct-acting antivirals in the treatment of chronic hepatitis C. Orv.

Authors: Nagy Csaba , Király István , Bánsághi Zoltán , Doros Attila
Published: May 2015

Revascularisation aims to create a patent lumen in an acutely or chronically occluded or stenosed vessel. Interventional radiology has developed and used minimally invasive methods for decades concurring surgical methods and medical therapy. Innovative fields in healthcare may be handicapped since revolutionary solutions usually gain wide acceptance slowly and the results of randomized controlled trials are reported late. At present endovascular recanalization, dilatation and stent placement have achieved a well-established role in the treatment of stenosis or occlusion of the aorta, and renal and peripheral arteries.

Published: May 2015

The development of efficient large-area organic light emitting diodes (OLED) requires reliable and easily processable charge generation layers (CGL) with low excess voltage drop and high optical transparency. OVPD offers the advantage of a precise control of layer morphology, composition and thickness and is a powerful method for the deposition of advanced OLED designs. In this work, electrical doping of organic semiconductors using OVPD is investigated and applied to stacked OLED utilizing inorganic/organic CGL. The organic p-type dopant NDP-9 of Novaled GmbH is used for doping the hole transport material N,N‘-diphenyl-N,N‘-bis(1-naphthylphenyl)-1,1‘-biphenyl-4,4‘-diamine (α-NPD) in an AIXTRON OVPD tool. A doping concentration of 8 vol.% of NDP-9 in α-NPD is found optimal for hole injection as well as conductivity. This dopant concentration was employed in CGL with the structure: electron transport material/LiF/Al/α-NPD:8 vol.% NDP-9. External quantum efficiencies (EQE) of 15%, 35% and 50% and luminous efficiencies of 37 lm/W, 45 lm/W and 45 lm/W at 1000 cd/m2 are demonstrated for single, double- and triple-unit green phosphorescent OLED, respectively.
Impact of low dose gamma irradiation on electronic carrier transport in AlGaN/GaN High Electron Mobility Transistors
Authors: Yadav Anupama , Flitsiyan Elena , Chernyak Leonid , Ren Fan , Pearton Stephen J. , Johnson Jerry Wayne , Lubomirsky Igor
Published: May 2015

AlGaN/GaN High Electron Mobility Transistors were exposed to 60Co gamma-irradiation to doses up to 300Gy. The impact of Compton- electron injection (due to gamma-irradiation) is studied through monitoring of minority carrier transport using Electron Beam Induced Current (EBIC) technique. Temperature dependent EBIC measurements were conducted on devices before and after exposure to the irradiation, which provide us with critical information on gamma-irradiation induced defects in the material. As a result of irradiation, minority carrier diffusion length increases significantly, with an accompanying decrease in the activation energy. This is consistent with the longer life time of minority carrier in the material’s valence band as a result of an internal electron injection and subsequent trapping of Compton electrons on neutral levels.

Published: May 2015

Sementes de Schizolobium amazonicum apresentam dormência física a qual pode ser quebrada por diferentes métodos de escarificação. Nesta pesquisa, os efeitos da escarificação das sementes em lixa e água quente sob os aspectos fisiológicos relacionados à germinação das sementes e à qualidade das plântulas obtidas foram avaliados. Sementes de S. amazonicum foram escarificadas pela (i) imersão em água a 100°C/ 2 min e pela (ii) fricção das sementes em lixa. Sementes não escarificadas foram utilizadas como testemunha. As seguintes variáveis foram avaliadas: viabilidade dos tecidos (por meio do teste de tetrazólio), taxa de germinação, índice de velocidade de germinação (IVG), taxa de embebição das sementes, depleção do endosperma e emergência, uniformidade e acúmulo de biomassa das plântulas resultantes. As sementes oriundas de ambos os tratamentos foram igualmente coradas pelo tetrazólio. A escarificação em lixa resultou em maior germinação, maior IVG, rápida embebição e depleção do endosperma em comparação às sementes escarificadas em água a 100°C/2 min. A emergência de plântulas e o índice de emergência foram maiores em sementes escarificadas em lixa, cujas plântulas apresentaram-se mais uniformes e com maior acúmulo de biomassa que aquelas obtidas após escarificação em água a 100°C/2 min. Do exposto, a escarificação de sementes de paricá em lixa é mais eficiente na promoção da germinação e produção de plântulas uniformes.
Multifunctional heterostructures integrated on Si (100)
Authors: Singamaneni Srinivasa Rao , Prater John T. , Narayan Jay
Published: May 2015

Complex oxide films and heterostructures exhibit a wide range of functional properties, including colossal magneto-resistance, magnetocaloric effects, coupled magnetic and polarisation (multiferroic) behaviour, and some interesting physical phenomena including spin, charge and orbital ordering. However, putting this functionality to work remains a challenge. To date, most of the work reported in the literature has dealt with heterostructures deposited on closely lattice-matched insulating substrates such as DyScO3 (DSO), NdGaO3 (NGO), MgO and SrTiO3 (STO). Unfortunately, these substrates are incompatible with existing complementary metal oxide semiconductor (CMOS)-based technology, where silicon (Si) (100) substrates dominate. This review covers the major advances in the integration of multifunctional (oxide and non-oxide) materials onto Si (100) substrates reported in the recent past by the authors’ group using pulsed laser deposition in conjunction with a novel layer growth approach called ‘domain-matching epitaxy’ (DME). This paper focuses on the growth of several important oxide systems, including BiFeO3 (BFO), La0·7Sr0·3MnO3 (LSMO), BaTiO3 (BTO), and non-oxide films including permalloy/MgO and Ni/MgO. It is shown that one can achieve thin-film epitaxy over an extended misfit scale by using the paradigm of DME. This will be critical for the future integration of multifunctional heterostructures onto CMOS-based chips in order to create smart structures for the next-generation solid-state devices. In addition, this paper explores the utility of using laser processing to introduce defect populations that induce magnetism in non-magnetic oxides such as STO and BTO as an alternative to incorporating more traditional magnetic layers into the structure.

While reliability index values of 0.86, 0.85 and 0.92 were obtained using Cronbach alpha. Means and grand means were used to analyze the research questions. The findings revealed a low extent utilization and inadequate ICT tool literacy among the academic staff in the federal universities in south east geo-political zone of Nigeria. It is therefore recommended that the academic staff avail themselves the opportunity of various conferences and workshops to acquire the needed skills for effective utilization of ICT tools.
Impact of Globalization on the Traditional African Cultures
Authors: Yankuzo Kabiru Ibrahim
Published: May 2015

There has been increasing concern over the years by the scholars and writers on how the world is being compressed into a single space now referred to as 'a global village'. Countries at various stages of development are increasingly forced to take account of an ever expanding interconnection of socio-cultural issues and economies in the management of their national affairs. The states are increasingly losing their capacity to govern and to regulate in an increasingly borderless world; with an increasing homogenization and domination of traditional African cultures. African societies are forced into accepting uniform moral principle of what is right and wrong within the global cultures. Scholars and writers often focus attention on economic aspect of globalization, while neglecting other aspects, more importantly its cultural aspect. This paper seeks to examine what exactly is globalization, and how can we best conceptualize this phenomenon? Lastly what are its impacts on the development of African cultural norms and values? These amongst others are the questions, which this paper seeks to examine using cultural convergence perspective as a guide.

Published: May 2015

The purpose of this study was to examine College of Education students’ perceptions of school psychologist’s roles and functions. Participants were 200 (164) students in College of Education, Katsina-Ala. A questionnaire was employed to collect the data. It was found that college students majoring in secondary education rated all roles/functions as significantly more important than those majoring in primary education (p < .05). Students majoring in secondary education and those majoring in primary education differed significantly in their expectation on who they thought should serve the various roles and functions of a school psychologist if a school psychologist is not available. NCE 2 rated all of the roles/functions significantly higher than did NCE 1 (p < .05). However, NCE 1 and NCE 2 did not differ significantly (p > .01) on who they thought should perform the various roles and functions of an unavailable school psychologist. Implications of the findings were also presented in this article.

Authors: Musa Aliyu
Published: May 2015

Although there is an increasing use of emerging technologies in the Library sector in higher education internationally and in Nigeria in particular, there is little evidence that it is used in transforming teaching and learning practice. Teaching and learning would have been more user friendly, with multiple positive recompense and positive feedback mechanism if emerging technologies are adequately put to use. Thus, the gap between technologies supported and used for teaching and the technologies used by students for learning has created pressure for educators and policy makers to come out with an up-to –date transformative approach towards effective and productive use of emerging technologies with a view to transform the education sector and encourage the use of emerging technologies in the library division. This paper seeks to highlight the available technologies in the sector and how to positively explore them. ICT and other sectors of the economy will also not be left out. It will also proffer a transformative approach on how such technologies can be utilized to the maximum for the benefit of teaching and learning and policy makers in particular, and the country‘s other sectors at large. The paper draws its data from Secondary source only.
