Authors: Hlavčová Kamila , Lapin Milan , Valent Peter , Szolgay Ján , Kohnová Silvia , Rončák Peter 
Published: January 2016

Abstract
In order to estimate possible changes in the flood regime in the mountainous regions of Slovakia, a simple physically-based concept for climate change-induced changes in extreme 5-day precipitation totals is proposed in the paper. It utilizes regionally downscaled scenarios of the long-term monthly means of the air temperature, specific air humidity and precipitation projected for Central Slovakia by two regional (RCM) and two global circulation models (GCM). A simplified physically-based model for the calculation of short-term precipitation totals over the course of changing air temperatures, which is used to drive a conceptual rainfall-runoff model, was proposed. In the paper a case study of this approach in the upper Hron river basin in Central Slovakia is presented. From the 1981–2010 period, 20 events of the basin’s most extreme average of 5-day precipitation totals were selected. Only events with continual precipitation during 5 days were considered. These 5-day precipitation totals were modified according to the RCM and GCM-based scenarios for the future time horizons of 2025, 2050 and 2075. For modelling runoff under changed 5-day precipitation totals, a conceptual rainfall-runoff model developed at the Slovak University of Technology was used. Changes in extreme mean daily discharges due to climate change were compared with the original flood events and discussed.
Inner zone terrain correction calculation using interpolated heights
Authors: Zahorec Pavol 
Published: January 2016

Abstract
The discrepancy between real heights of gravity points and the elevation model has a significant impact on the terrain corrections calculation especially within the inner zone. The concept of interpolated heights of calculation points used instead of measured ones within the specified inner zone can considerably decrease the resulting errors. The choice of appropriate radius of the inner zone for use of interpolated heights is analysed on synthetic topography model as well as real data. The tests with synthetic models showed the appropriate radius of this zone is proportional to the deformation wavelength of the model. Simple statistical analysis of a particular elevation model can give an estimate of the appropriate radius for the calculation using interpolated heights. A concept with interpolated heights in the zone 0–250 m is used in actual practice in Slovakia. The analysis of regional gravity data from the Tatry Mountains test area indicates the searched radius should be about 100 m. Detailed gravity measurements from different areas showed the searched radius does not play so important role but the use of interpolated heights instead of measured ones is still relevant. The more reasonable method instead of using interpolated heights is also presented when calculating the topographic effect.
Facilitated Transport of Propylene Through Composite Polymer-Ionic Liquid Membranes. Mass Transfer Analysis

Published: January 2016

Abstract
Separation of light gaseous olefins from paraffin’s of the refinery process off-gasses has been traditionally performed by cryogenic distillation, which is a highly capital and energy intensive operation. This handicap creates an incentive for the investigation of alternative olefin/paraffin separation technologies. In this regard, membrane technology supposes a potential solution for process intensification. Previous works of our research group reported the use of facilitated transport composite membranes integrating the use of PVDF-HFP polymer, BMImBF4 ionic liquid and AgBF4 silver salt. In this type of membranes, the silver cations react selectively and reversibly with the olefin, allowing the separation via mobile and fixed carrier mechanisms. Ionic liquids were selected as membrane additives because in addition to their negligible vapor pressure that avoids solvent losses by evaporation, they provide stability to the metallic cation dissolved inside, and modify the structure improving the facilitated transport. This technology offers a commercial attractive separation alternative thanks to their modular form of operation, high values of selectivity and permeability and low operational costs. In the present work, propane/propylene permeation experiments involving the use ionic liquids and different membrane compositions were performed. Moreover, basing on the transport and equilibrium parameters previously obtained, a mathematical model description of the system will be proposed fitting the remaining parameters and allowing the design and optimization of the propane/propylene separation process at industrial levels.
Dzierżoniów Town in the eyes of its residents – a study report
Authors: Raszkowski Andrzej 
Published: January 2016

Abstract
Dzierżoniów’s residents definitely represent one of its most valuable resources. Its development and improvement of the generally approached life quality depends on their involvement in solving social and economic problems, their entrepreneurship and creativity. It should also be emphasized that the vast majority of surveyed residents are in favour of their city development. This phenomenon is based on the principle of mutual dependencies, i.e. the better the city functioning, the better living the conditions provided for its residents. On the other hand, the more active and involved the residents are the more effective is their support for the city development (e.g. by their involvement in NGOs’ activities). The presented article was prepared based on the survey studies ordered by Dzierżoniów’s Town Office and conducted in the period July–August 2013 which covered, among others, the city residents (422 respondents). The research was carried out within the framework of one of the stages in developing Dzierżoniów’s Local Sustainable Development Strategy for the period 2014-2020. The purpose of the study is to discuss and assess the selected functional areas of Dzierżoniów Town (geographic environment, economy, technical infrastructure, social infrastructure, city management) based on its residents’ opinions.
Nrf2 activation in the treatment of neurodegenerative diseases: a focus on its role in mitochondrial bioenergetics and function
Authors: Esteras Noemí , Dinkova-Kostova Albena T. , Abramov Andrey Y. 
Published: January 2016

Abstract
The nuclear factor erythroid-derived 2 (NF-E2)-related factor 2 (Nrf2) is a transcription factor well-known for its function in controlling the basal and inducible expression of a variety of antioxidant and detoxifying enzymes. As part of its cytoprotective activity, increasing evidence supports its role in metabolism and mitochondrial bioenergetics and function. Neurodegenerative diseases are excellent candidates for Nrf2-targeted treatments. Most neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, frontotemporal dementia and Friedreich’s ataxia are characterized by oxidative stress, misfolded protein aggregates, and chronic inflammation, the common targets of Nrf2 therapeutic strategies. Together with them, mitochondrial dysfunction is implicated in the pathogenesis of most neurodegenerative disorders. The recently recognized ability of Nrf2 to regulate intermediary metabolism and mitochondrial function makes Nrf2 activation an attractive and comprehensive strategy for the treatment of neurodegenerative disorders. This review aims to focus on the potential therapeutic role of Nrf2 activation in neurodegeneration, with special emphasis on mitochondrial bioenergetics and function, metabolism and the role of transporters, all of which collectively contribute to the cytoprotective activity of this transcription factor.

Authors: Wang X. , Kong D. , Ma Z. , Zhao R. 
Published: January 2016

Abstract
The effect of edible films based on carrot puree, chitosan, corn starch, gelatin, glycerol and cinnamaldehyde on fresh-cut carrots was studied during storage. Several parameters, such as firmness, colour, weight loss, total carotenoids, total phenols, polyphenol oxidase (PPO) activity and peroxidase (POD) activity in coated carrots were determined at regular intervals and then compared with the uncoated carrots throughout the storage period. Significant and expected changes were observed in all carrot samples that were compared. The coating treatment significantly (P < 0.05) delayed the senescence, reduced the deterioration of exterior quality and retained total carotenoids well compared with control (P < 0.05). In addition, significant inhibition of PPO activity (P < 0.05) and POD activity (P < 0.05) as well as reduced accumulation of polyphenols (P < 0.05) were observed for all coated samples. All of these favourable responses induced by coating treatment on minimally processed fresh-cut carrots showed beneficial physiological effects, which would give some useful references to the fresh-cut fruit and vegetable processing industry and satisfy people’s requirements allowing for extending product shelf life without negatively affecting the sensory quality or acceptability.
The transformative potential of action research and ICT in the Second Language (L2) classroom

Published: January 2016

Abstract
This study shows the transformative potential of action research and information and communications technology (ICT) in the second language (L2) classroom. Two enquiries from teacher-researchers are detailed in the article. Their engagement in a collaborative professional development Masters programme was pivotal in designing and implementing ICT creatively in their classroom. Gee (2008) advocates the use of the preferred media of our classroom students in order to address their learning. Prensky (2001) urges us to feel the fear and do it anyway with our digital native classes. A post-primary teacher and a primary teacher show us how they felt the fear, did it and transformed aspects of their own teaching in the process. The Masters programme required the teachers to engage with innovative practices, informed by their own values, and integrate technologies that were new to them into their repertoire of classroom strategies. Peer validation meetings with colleagues enabled meaningful insights to emerge from the research. The teachers improve and transform their second language (L2) practice in collaboration and validation with others.

Error analysis for the operator marching method
applied to range dependent waveguides
Authors: Li Peng , Liu Keying , Zuo Weibing , Zhong Weizhou 
Published: January 2016

Abstract
The relations between stability and accuracy of the operator marching method (OMM)
are usually conflicting in waveguides with strong range dependence. To explain this phenomenon,
this study intends to present an error estimate for the OMM in range dependent waveguides. We utilize “approximation level”
to measure truncation error for a marching method in various range step sizes. Then, the error estimate is developed to analyze
the performances of the OMM. Through an error analysis, we verify the following features of the OMM:
(i) it is valid to apply the OMM in slowly varying waveguides with very large range step sizes;
(ii) the OMM may blow up suddenly when the range dependence is strong and the step size is extremely small in the same time.
We also develop a three-number set to describe the stability and accuracy level of a general marching method for computing
wave propagation in a waveguide. In the end, extensive numerical experiments are implemented to verify the correctness
of the error analysis.
Long-term first line medical treatment in a 4-year-old girl with Xq26.3 microduplication-negative somatotropinoma. Case report and literature review

Published: January 2016

AbstractGrowth hormone (GH) secreting adenoma represents a therapeutic challenge in childhood. Because of its rarity no treatment guidelines are available and pediatric management often results from recommendations issued for adults. We report a case of a 4-year-old girl with somatotropinoma successfully treated with only medical treatment. She presented with tall stature and history of growth acceleration. Imaging and laboratory confirmed the diagnosis of GH secreting macroadenoma. She started medical treatment with a somatostatin analogue and a dopamine agonist. During an 8-year follow-up period, a good clinical control of the disease and a shrinkage of the adenoma have been demonstrated. At the last observation she achieved normal near-adult height and pubertal development. According to our experience and limited literature evidences, first line treatment with somatostatin analogues can be attempted in patients with somatotropinoma. This approach seems to be able to control the clinical course of the disease, allowing to postpone transphenoidal surgery to adult age or to avoid it.

Authors: Kobayashi Yuichiro 
Published: January 2016

AbstractThe present study investigated differences in rhetorical preferences in L2 writings among different L1 groups. This study compared the use of metadiscourse markers in L2 essays and identified discourse devices used to distinguish different L1 groups. The essays originated from the International Corpus Network of Asian Learners of English (ICNALE) compared six L1 groups (viz., Chinese, Indonesian, Japanese, Korean, Taiwanese, and Thai) based on the frequency of metadiscourse markers. I utilized heat map with hierarchical clustering to investigate differences in metadiscourse among the six learner groups. The results suggested a substantial difference in the use of metadiscourse markers between East Asian groups (viz., Chinese, Japanese, Korean, and Taiwanese) and Southeast Asian groups (viz., Indonesian and Thai). Furthermore, each learner group displayed the specific characteristics of metadiscourse, which offer suggestions for improving L2 learners’ writings.

Članek se zabyva vyhodnocenim průtokovych vlastnosti (průtokovy součinitel, součinitel přične a tečne rotace) saciho kanalu užitim jak 3-D CFD simulace, tak měřeni. Byla provedena citlivostni studie různych parametrů simulace. Nejdůležitějši jsou vlastnosti sitě a použite modely turbulence (uvažovane modely: LES, PANS a RANS). Co se tyka sitě, tak kritickym parametrem je konfigurace v těsne blizkosti stěny - tloušťka a počet vrstev těsně u stěny maji velky vliv na průtok, avšak součinitele přične a tečne rotace na tom teměř nezavisi. Odtud plyne, že tyto parametry sitě lze považovat za ladici parametry CFD modelu. Co se tyka velikosti oka sitě, 2 velikosti byly testovany (0.6 a 0.3 mm). Ukazalo se, že ani jedna z těchto siti neni dostatečně jemna pro korektni aplikaci LES. A tedy PANS funguje spiše jako RANS. Z hlediska modelů turbulence je PANS jevi jako nejlepši možnost, protože kombinuje vyhody jak LES, tak RANS. Obecně je možne konstatovat, že lze dosahnout relativně dobre shody na průtoku, ale součinitele přične a tečne rotace jsou problematicke, neboť byla dosažena pouze kvalitativni shoda.

A Novel Approach to Enhance Performance of Multilayer Coated Carbide Insert in Hard Turning
Authors: Shihab Suha K. , Khan Zahid A. , Siddiquee Arshad Noor , Khan Noor Zaman 
Published: January 2016

Abstract
Flank wear of multilayer coated carbide (TiN/TiCN/Al2O3/TiN) insert in dry hard turning is studied. Machining under wet condition is also performed and flank wear is measured. A novel micro-channel is devised in the insert to deliver the cutting fluid directly at the tool-chip interface. Lower levels of cutting parameters yield the minimum flank wear which is significantly affected by cutting speed and feed rate. In comparison to dry and wet machining, insert with micro-channel reduces the flank wear by 48.87% and 3.04% respectively. The tool with micro-channel provides saving of about 87.5% in the consumption of volume of cutting fluid and energy.
Law and the Volunteer: The Uncertain Employment and Tort Law Implications of the Altruistic Worker
Authors: Mead Joseph 
Published: January 2016

AbstractAn individual who donates service to a nonprofit organization raises unsettled questions of that volunteer’s status under tort and labor law. Cryptic legislative language and inconsistent judicial precedent undermine predictability for volunteers and nonprofit managers alike, and the standards fail to reflect a coherent balance between the legitimate expectations of altruistic workers and the realities of the nonprofit-volunteer relationship.
Development of the Chalmers Grouped Actinide Extraction Process

Published: January 2016

Abstract
Several solvents for Grouped ActiNide EXtraction (GANEX) processes have been investigated at Chalmers University of Technology in recent years. Four different GANEX solvents; cyclo-GANEX (CyMe4- -BTBP, 30 vol.% tri-butyl phosphate (TBP) and cyclohexanone), DEHBA-GANEX (CyMe4-BTBP, 20 vol.% N,N-di-2(ethylhexyl) butyramide (DEHBA) and cyclohexanone), hexanol-GANEX (CyMe4-BTBP, 30 vol.% TBP and hexanol) and FS-13-GANEX (CyMe4-BTBP, 30 vol.% TBP and phenyl trifluoromethyl sulfone (FS-13)) have been studied and the results are discussed and compared in this work. The cyclohexanone based solvents show fast and high extraction of the actinides but a somewhat poor diluent stability in contact with the acidic aqueous phase. FS-13-GANEX display high separation factors between the actinides and lanthanides and a good radiolytic and hydrolytic stability. However, the distribution ratios of the actinides are lower, compared to the cyclohexanone based solvents. The hexanol-GANEX is a cheap solvent system using a rather stable diluent but the actinide extraction is, however, comparatively low.
Morphological classification of conspecific birds from closely situated breeding areas – A case study of the Common Nightingale
Authors: Kováts Dávid , Harnos Andrea 
Published: January 2016

Abstract
In this paper, a complex morphological comparison of four Common Nightingale groups (Luscinia megarhynchos) is demonstrated. In total, 121 territorial nightingales were mist-netted and measured individually on four study areas called ‘Bódva’, ‘Felső-Tisza’, ‘Szatmár-Bereg’ and ‘Bátorliget’ in the North-Eastern part of Hungary in 2006–2013. To distinguish groups by morphology, Classification and Regression Trees (CART), Random Forest (RF) and Linear Discriminant Analysis (LDA) methods were used. Comparison of the four studied Common Nightingale groups shows substantial morphological differences in the length of the second, the third and the fourth primaries (P2, P3, P4), in bill length (BL) and bill width (BW), while other characteristics showed greater similarities. Based on the results of all the applied classification methods, birds originated from Szatmár-Bereg were clearly distinguishable from the others. The differences in morphology can be explained by interspecific competition or phenotypic plasticity resulting from the change of ecological, environmental parameters. Our case study highlights the advantageous differences of the classification methods to distinguish groups with similar morphology and to choose important variables for classification. In conclusion, broad application of the classification methods RF and CART is highly recommended in comparative ecological studies.
Eco-geographical variation in the diet of the Barn Owl (Tyto alba) in mountainous areas of France
Authors: Halliez Guillaume , Becel Clémence Marie Lucie , Canella Victoria 
Published: January 2016

Abstract
Because of the worldwide distribution of the Barn Owl (Tyto alba) and the easily way to find its pellets, it is often used to diet studies. To investigate the eco-geographical impact of mountainous areas on its diet, we conducted studies in the Jura, Alpes, Central and Pyrénées mountains and we also did pellet analysis from 8 sites in the Jura mountains. Analysis of the tooth and skull content of pellets allowed us to draw up two types of change in the diet of Tyto alba in correlation with mountain elevation. The first one concerns the Jura, Alpes and Central mountains, where the diversity of the diet declines with the increase in elevation. The second one concerns the Pyrénées mountains, where there is no change in the diversity of the diet, perhaps because of the higher diversity of small mammals caused by mediterranean influence. Thus, it seems that elevation cau ses a decrease in diet diversity of Tyto alba in continental mountains (Jura, Alpes and Central mountains) probably because of more homogeneous landscapes dedicated to grass production. However, in Mediterranean mountains (Pyrénées), a more diversified small mammal guild provides a constant level of diet diversity.
