Published: June 2016

Abstract

Objectives: Bilateral carotid artery stenting (BCAS) in one session is relatively rare procedure. However, clear recommendations still do not exist. The aim of our study was to analyze efficacy and safety of the BCAS performed by single operator in our center.

Material and Methods: A retrospective analysis of 95 carotid angioplasty with stent implantation (CAS) patients performed in our center, totally 9 patients (8 males and 1 female, age 59-83, average 69) was identified where simultaneous BCAS was performed. All patients had bilateral hemodynamic significant stenosis (≥ 70 %), and all patients had symptomatic stenosis.

Results: Only 1 patient was without any complication. The most frequent complications were arterial hypotension. However, duration of stay on the Intensive Care Unit, or hospitalisation was not prolonged. From serious complications we noticed one case of periprocedural filter occlusion and one patient died 30 days after procedure. No other serious complications were in the BCAS group noticed.

Conclusion: Because of limited data it is not possible to make any clear conclusions or recommendations from the results of our study. Our data show that probably BCAS appears to be safe and effective way in the treatment of bilateral carotid artery stenosis in high-risk population.

Abstract
Reactivity of energy gypsum was investigated. The method is based on the conversion reaction of aqueous suspension of gypsum with ammonium carbonate solution. Rate of the conversion of all investigated samples, including gypsum originating from flue gas desulphurization (FGD), was high and 80 % conversion was achieved during one hour. It was found that there is a correlation between BET specific surface and the rate of the conversion reaction.
Effect of incorporating potato dietary fibre to wheat dough on the quality of baked rolls
Authors: Lauková Michaela , Kohajdová Zlatica , Karovičová Jolana 
Published: June 2016

Abstract
The effect of incorporation of commercial potato dietary fibre at different levels (1, 3, 5 and 10 %) on wheat flour dough rheology, qualitative and sensory properties of baked rolls was evaluated. Potato dietary fibre exhibits good hydration properties (water holding, water retention and swelling capacity). Its addition into wheat dough increased water absorption, prolonged dough stability and dough development time. Also, it was found that the potato fibre incorporation to wheat rolls negatively affects both volume and specific volume, and cambering of baked rolls. Sensory evaluation showed that rolls with the addition of potato dietary fibre at levels 1 and 3 % had high overall acceptability.
Carbon source utilization and hydrogen production by isolated anaerobic bacteria
Authors: Jame R. , Zelená V. , Lakatoš B. , Varečka Ľ. 
Published: June 2016

Abstract
Five bacterial isolates were tested for their ability to generate hydrogen during anaerobic fermentation with various carbon sources. One isolate from sheep rumen was identified as Escherichia coli and four isolates belonged to Clostridium spp. Glucose, arabinose, ribose, xylose, lactose and cellobiose were used as carbon sources. Results showed that all bacterial strains could utilize these compounds, although the utilization of pentoses diminished growth yield. The excretion of monocarboxylic acids (acetate, propionate, formiate, butyrate) into medium was changed after replacing glucose by other carbon sources. Di- and tricarboxylic acids were excreted in negligible amounts only. Spectra of excreted carboxylic acids were unique for each strain and all carbon sources. All isolates produced H2 between 4—9 mmol·L−1 during the stationary phase of growth with glucose as energy source. This value was dramatically reduced when pentoses were used as carbon source. Lactose and cellobiose, starch and cellulose were suitable substrates for the H2 production in some but not all isolates. No H2 was produced by proteinaceous substrate, such as blood. Results show that both substrate utilization and physiological responses (growth, excretion of carboxylates, H2 production) are unique functions of each isolate.
CRISPR/Cas in genome defense and gene editing
Authors: Kryštofová Svetlana 
Published: June 2016

Abstract
Targeted genome editing using engineered nucleases such as ZFNs and TALENs has been rapidly replaced by the CRISPR/Cas9 (clustered, regulatory interspaced, short palindromic/ CRISPR-associated nuclease) system. CRISPR/Cas9 technology represents a significant improvement enabling a new level of targeting, efficiency and simplicity. Gene editing mediated by CRISPR/Cas9 has been recently used not only in bacteria but in many eukaryotic cells and organisms, from yeasts to mammals. Other modifications of the CRISPR-Cas9 system have been used to introduce heterologous domains to regulate gene expressions or label specific loci in various cell types. The review focuses not only on native CRISPR/Cas systems which evolved in prokaryotes as an endogenous adaptive defense mechanism against foreign DNA attacks, but also on the CRISPR/Cas9 adoption as a powerful tool for site-specific gene modifications in fungi, plants and mammals.

Published: June 2016

Abstract
System modelling using Unified Modelling Language (UML) is the task that should be solved for software development. The more complex software becomes the higher requirements are stated to demonstrate the system to be developed, especially in its dynamic aspect, which in UML is offered by a sequence diagram. To solve this task, the main attention is devoted to the graphical presentation of the system, where diagram layout plays the central role in information perception. The UML sequence diagram due to its specific structure is selected for a deeper analysis on the elements’ layout. The authors research represents the abilities of modern UML modelling tools to offer automatic layout of the UML sequence diagram and analyse them according to criteria required for the diagram perception.

The mathematical model of trajectories spindle with lumped parameters that allows to define the position of the spindle with regard the simultaneous influence of design parameters, geometrical deviations ofform, temperature deformation bearing surfaces, the random nature of operational parameters and technical loads of hydrostatic bearings has been developed. Based on the results of numerical modeling the influence of shape errors of bearing surface of hydrostatic bearing on the statistical characteristics of the radius vector trajectories of the spindle by varying the values rotational speed of the spindle and oil pressure in front hydrostatic bearing has been developed. The obtained statistical regularities of precision spindle unit have been confirmed experimentally. It has been shown that an effective way to increase the precision of spindle units is to regulate the size of the gap in hydrostatic spindle bearings. The new design of an adjustable hydrostatic bearing, which can improve the accuracy of regulation size gap has been proposed.

Published: June 2016

Abstract
In order to create realistic loop primitives suitable for the fast computer-aided design (CAD) of the flat knitted fabric, we have a research on the geometric model of the loop as well as the variation of the loop surface. Establish the texture variation model based on the changing process from the normal yarn to loop that provides the realistic texture of the simulative loop. Then optimize the simulative loop based on illumination variation. This paper develops the computer program with the optimization algorithm and achieves the loop simulation of different yarns to verify the feasibility of the proposed algorithm. Our work provides a fast CAD of the flat knitted fabric with loop simulation, and it is not only more realistic but also material adjustable. Meanwhile it also provides theoretical value for the flat knitted fabric computer simulation.

Published: June 2016

Summary
A method of discriminant variable determination was used to visualize the division of oak trees into Kraft classes. Usual discriminant variables and several types of kernel discriminant variables were studied. For this purpose the traits of oak (Quercus L.) trees, measured on standing trees, were used. These traits included height of tree, breast height diameter and crown projection area. The use of the Gaussian kernel and modified Gaussian kernel enabled the clearest division into Kraft classes. In particular, the latter method proved to be the most effective.

“I’m Just Going to Buy That!”: Confronting Consumerism in Teacher Education
Authors: Ashworth Elizabeth , Steele Astrid 
Published: June 2016

Abstract
As educators at a faculty of education, the authors found that teacher candidates (TCs) invariably purchased new materials whenever they had an assignment requiring some form of construction activity. They were concerned about this learned, consumer behavior; lessons of moderation in using the Earth’s resources are important elements of sustainability education. Humans are consumers in both a natural and an anthropological sense, but are capable of sustainable consumerism. Therefore, the authors wanted to promote moderation/sustainable consumerism through an educational intervention in their teacher-education classes. Inspired by Selby’s (2011) third proposition for education for sustainable contraction, they revised an existing art/science integration project where constructions would be created from recycled and/or natural materials. The TCs’ constructions, process work, and Reflection papers provided insight into their creative thinking, and learning, regarding sustainable consumerism.
Perceived Affordances, Tensions, and Complementarities in the Physical and Digital Environments Frequented by Future Teachers
Authors: Pruneau Diane , Kerry Jackie , Freiman Viktor , Langis Joanne , Bizid Mohamed 
Published: June 2016

Abstract
Is future teachers’ contact with the physical environment significant enough for them to choose to educate their students about sustainability? These digital natives stand out from previous generations by their way of living. The research based on grounded theory was aimed at understanding future teachers’ relationships with physical and technological environments. The analysis of interviews, with Moncton and Montreal teacher education students, reveals that future teachers maintain a sporadic relation to the natural environment. They are still conscious that nature provides them calmness, rejuvenation and beauty. The Internet offers them distraction, social affiliation, personalized information, and facilitates their tasks and contact with the World. Future teachers are critical and cautious in their use of ICT but are however not much involved in the environmental cause. The research emphasizes the need to work on future teachers’ relationship to the physical environment with outdoor activities to get to know, appreciate, analyze and improve the natural and urban environments.
Primary Science Teaching – Is it Integral and Deep Experience For Students?
Authors: Timoštšuk Inge 
Published: June 2016

Abstract
Integral and deep pedagogical content knowledge can support future primary teachers’ ability to follow ideas of education for sustainability in science class. Initial teacher education provides opportunity to learn what and how to teach but still the practical experiences of teaching can reveal uneven development of student teachers’ professionality. The aim of the study is to describe how future primary teachers reflect on their experiences about science teaching and what components of science pedagogical content knowledge they see as meaningful. A questionnaire and interviews were used. The results reveal the deep impact of teaching practice on students’ understanding of the role of a teacher in supporting pupils’ acquisition of scientific skills. The experiences described are related more to teaching and learning in general and less with science-specific factors. Nevertheless, students described changes in mission e.g. how they learned about their role through pupils’ achievements and thinking about science. Changes in professional identity were mentioned rarely but this could point to an underestimated resource issue for teacher education. Positive changes in professional identity may help students to decide to choose more integral strategies in science teaching and thus promote more sustainability oriented teaching.
Language Education for Sustainable Development
Authors: Zygmunt Tomasz 
Published: June 2016

Abstract
Nowadays, education for sustainable development starts covering wider and wider spheres of interest and human activity. Out of the three main spheres of interest, such as environmental, economic, and socio-cultural, the first two mentioned here seem to be given more attention than the sphere of socio-cultural activity. In this respect, the aim of the present paper is to redirect the concern of administrators, researchers and educators preoccupied with sustainability to issues such as equal opportunity, tolerance, respect, and especially foreign language education, being component parts of the socio-cultural sphere. Undoubtedly, competence in the socio-linguistic field becomes the decisive element in negotiations and international contacts which require from the language user to be tactful and tolerant. Since sustainability is not a local issue, all sustainability related problems ought to be discussed on the macro scale, which requires an internationally shared means of communication such as language. Although no name of any language appears in the paper, it becomes evident that the attention is directed towards English as an internationally recognized language or, if necessary, any other language which might serve as a means of communication on the macro scale.
In the course of discussion, both the needs and limitations appearing in the process of education for sustainable development are presented and supported by opinions and examples. The paper ends in conclusions directly related to real-life situations, and gives implications to be utilized in the educational process directed at sustainable development.
Normative Framework as the Basis for Quality Financial Reporting in the Republic of Slovenia, the Republic of Macedonia and the Republic of Serbia
Authors: Ranđelović Dragana , Đukić Tadija 
Published: June 2016

Abstract
Quality of financial reporting is the precondition for the effective functioning of capital market due to the globalization of business. In the countries of Eastern and Central Europe, during the period of socialism, accounting and preparation of annual accounts was adapted for needs of planned economy. Today, it is necessary to work on harmonization national with international legislation. Also, they need to promote a culture of financial reporting, because economic entities do not understand the essential role and importance of financial reporting for business potential. In this paper, we consider Slovenia’s, Macedonia’s and Serbia’s normative framework of financial reporting system, in order to give the assessment of the current situation and pointed out the possible directions of improvement of this process. The comparative analysis of legal and professional solutions, which regulates financal reporting system in these countries, we learned some inconsistencies of their legislation in relation to international regulations, especially in the part of financial reporting for small and micro entreprises. In Serbia and Macedonia, perceived insufficient engagement of of professional organizations and bodies, which requires the reaction of the country in terms of defining and monitoring the implementation of regulations governing the conditions and responsibility for performing accounting and auditing work. This would allow business entities to access financial sources under favourable terms, raising their competitive advantages to quality financial information within financial reports, as well as further development of entrepreneurial activity, which is the generator of the most developed economies in the world.
Common fixed point of Jungck-Kirk-type iterations for non-self operators in normed linear spaces
Authors: Akewe Hudson , Mogbademu Adesanmi 
Published: June 2016

Abstract
In this paper, we introduce Jungck-Kirk-multistep and Jungck-Kirk-multistep-SP iterative schemes and use their strong convergences to approximate the common fixed point of nonself operators in a normed linear Space. The Jungck-Kirk-Noor, Jungck-Kirk-SP, Jungck-Kirk-Ishikawa, Jungck-Kirk-Mann and Jungck-Kirk iterative schemes follow our results as corollaries. We also study and prove stability results of these schemes in a normed linear space. Our results generalize and unify most approximation and stability results in the literature.

Tree height distribution dynamics in young naturally regenerated study plots
Authors: Kängsepp Vivika , Kangur Ahto , Kiviste Andres 
Published: June 2016

Abstract
Growth assessment of young stands gives the possibility of assessing forest site potential, tree species-dependent competition and developing realistic predictions for the following periods. The study is conducted in naturally regenerated broadleaves dominated stands in 2005 at Järvselja Training and Experimental Forest Center. The current study material is collected from 9 study plots established in three forest stands (regeneration felling years respectively 1996, 2000 and 2002). The study plots were re-measured 4–6 times respectively between the years of 2006 and 2012. The Weibull distribution function fit for empirical height distributions in consecutive years was tested and the estimated Weibull parameters were analysed. Results indicate that empirical height distributions of young regenerated forests do not fit well to theoretical distributions, but in many cases, empirical and theoretical distribution are similar. The Weibull distribution shape parameter was related to the maximum height and range of the height, and the scale parameter was related to the mean, quadratic mean and median height.
Microwave-assisted preparation of almond shell-based activated carbon for methylene blue adsorption
Authors: Du Chunfeng , Yang Hongbing , Wu Zhansheng , Ge Xinyu , Cravotto Giancarlo , Ye Bang-Ce , Kaleem Imdad 
Published: June 2016

Abstract
This study reports the synthesis of a novel adsorbent, hereinafter named almond shell-based activated carbon (ASAC), from waste almond shells (AS) via exposure to microwave radiation and the use of ZnCl2 as a chemical activator. Synthetic conditions were further elaborated using the response surface methodology to optimize the adsorption capacity of ASAC for methylene blue (MB) dye. The optimized ASAC preparation conditions were found to be as follows: a mass (ZnCl2/AS) ratio of 3:1 (w/w) and microwave heating time period of 15 min at 900 W. A maximum ASAC yield of 39.67% and a MB adsorption capacity of 314.20 mg/g were obtained. ASAC was also characterized by N2 adsorption-desorption measurement, scanning electron microscopy (SEM), Fourier-transform infrared spectrometry (FTIR), X-ray photoelectron spectroscopy (XPS), and point of zero charge measurement. Optimized ASAC had a Brunauer-Emmett-Teller surface area of 839.60 m2/g and a total volume of 0.406 cm3/g. FTIR and XPS analysis exhibited a decline in oxygen-containing groups of ASAC as compared with AS. The adsorption behavior of ASAC for MB was fitted well to the pseudo-second-order model and the Langmuir isotherm model. These findings support the ease of preparation and cost effectiveness that make ASAC promising for use in environmental remediation.
