Published: January 2017

The quality of tourism education provided at vocational schools could be achieved through a two-way interaction between the school and the students. In order for tourism education provided at vocational schools aiming to train mid-level human resources for the tourism sector to be at desired quality, it is of paramount importance to know the levels of expectations, perceptions, and motivation of students, who are the most important elements of education.This study aimed to determine students’ pre-education expectations, perceptions developed in the education process and finally their motivation regarding the tourism education provided. Data were collected through questionnaires consist of a personal information and three scales (motivation, expectation and perception scales for tourism education). In this study, it was detected that the levels of expectations that 423 students receiving associate degree tourism education had prior to tourism education affected the levels of perceptions formed in the process and motivation positively. However, as a result of the fact that the expectations of the students who had high expectations prior to tourism education were not met during their experiences, their perceptions fell compared to the expectation and they had motivation at the rate of the perceptions formed. It was revealed that vocational schools were insufficient to meet student expectations.

Published: January 2017

A 62 year-old caucasian male was admitted in our pulmonary hypertension expert center with initial diagnosis of pulmonary veno-occlusive disease for validation and specific treatment approach. Routine examinations revealed no apparent cause of pulmonary hypertension. Patient was referred for a thorax contrast enhanced multi-slice computed tomography which revealed extensive bilateral thrombi in pulmonary lower lobe arteries, pleading for chronic post embolic lesions. A right heart catheterization and pulmonary angiography confirmed the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH). Following the local regulations, the patient underwent thrombophilia screening including molecular genetic testing, with positive findings for heterozygous for VCORK1 -1639G>A gene single nucleotide polymorphism, PAI-1 4G/5G and factor II G20210A gene. With heterozygous genetic profile of 3 mutations he has a genetic predisposition for developing a thrombophilic disease which could be involved in the etiology of CTEPH. Familial screening was extended to descendants; the unique son was tested with positive results for the same three genes. Supportive pulmonary hypertension drug therapy was initiated together with patient self-monitoring management of oral anticoagulation therapy. For optimal control of targeted anticoagulation due to a very high risk of thrombotic state the patient used a point-of-care device (CoaguChek®XS System, Roche Diagnostics) for coagulation self-monitoring.

Published: January 2017

Polytetrafluoroethylene (PTFE)/Kevlar fabric or fabric composites with excellent tribological properties have been considered as important materials used in bearings and bushing, for years. The components’ (PTFE, Kevlar, and the gap between PTFE and Kevlar) distribution of the PTFE/Kevlar fabric is uneven due to the textile structure controlling the wear process and behavior. The components’ area ratio on the worn surface varying with the wear depth was analyzed not only by the wear experiment, but also by the theoretical calculations with our previous wear geometry model. The wear process and behavior of the PTFE/Kevlar twill fabric were investigated under dry sliding conditions against AISI 1045 steel by using a ring-on-plate tribometer. The morphologies of the worn surface were observed by the confocal laser scanning microscopy (CLSM). The wear process of the PTFE/Kevlar twill fabric was divided into five layers according to the distribution characteristics of Kevlar. It showed that the friction coefficients and wear rates changed with the wear depth, the order of the antiwear performance of the previous three layers was Layer III>Layer II>Layer I due to the area ratio variation of PTFE and Kevlar with the wear depth.

Authors: Szulc Piotr , Tietze Tomasz , Wójs Kazimierz
Published: January 2017

This paper presents studies carried out in a pilot-scale plant for recovery of waste heat from a flue gas which has been built in a lignite-fired power plant. The purpose of the studies was to check the operation of the heat recovery system in a pilot scale, while the purpose of the plant was recovery of waste heat from the flue gas in the form of hot water with a temperature of approx. 90 °C. The main part of the test rig was a condensing heat exchanger designed and built on the basis of laboratory tests conducted by the authors of this paper. Tests conducted on the pilot-scale plant concerned the thermal and flow parameters of the condensing heat exchanger as well as the impact of the volumetric flow rate of the flue gas and the cooling water on the heat flux recovered. Results show that the system with a condensing heat exchanger for recovery of low-temperature waste heat from the flue gas enables the recovery of much higher heat flux as compared with conventional systems without a condensing heat exchanger.

Published: January 2017

Automated logistic systems are becoming more
widely used within enterprise logistics processes. Their
main advantage is that they allow increasing the efficiency
and reliability of logistics processes. In terms of evaluating
their effectiveness, it is necessary to take into account
the economic aspect of the entire process. However, many
users ignore and underestimate this area,which is not correct.
One of the reasons why the economic aspect is overlooked
is the fact that obtaining information for such an
analysis is not easy. The aim of this paper is to present the
possibilities of computer simulation methods for obtaining
data for full-scale economic analysis implementation.

Published: January 2017

For more than two decades the family business enterprises of the first generation (generation of founders) are more and more dominating in the category of today’s small and medium–sized enterprises in the Czech Republic. The necessary legal background defining the legal relationships and rights of all participating persons was, however, limited to general provisions in the Commercial Code that has not solved many of the problems associated thereto. Only in 2012 the new Czech Civil Code, Act. No 89/2012 Coll., introduced the institute of family enterprise as completely new term in the Czech Civil law. The presented paper aims to analyse the key rules of this new legal regulation, focusing on significant aspects of the institute in the context of commercial law and family law, as well as, to highlight the potential weaknesses and gaps existing in the regulation.
Slovak Income Tax Legislation in Terms of EU Secondary Law Transposition
Authors: Krajčírová Renáta
Published: January 2017

The article deals with the integration process of implementation of European Union secondary law into the Slovak tax legislation. In particular, the article analyses whether provisions of (i) EU Parent Subsidiary Directive, (ii) EU Interest and Royalty Directive and (iii) EU Merger Directive are implemented into the Slovak Income Tax Act. Following our research, it should be noted that in general, the Slovak tax legislation has adopted the EU secondary law, in particular, the Parent Subsidiary and Interest and Royalty Directives have been implemented. It should be noted that the profit distributions are not subject to tax in Slovakia. It follows that interest and royalty are not subject to tax and is applicable to EU associated companies. Following the Slovak implementation of EU Merger Directive, merger transactions are generally treated as not giving rise to a capital gain. As a result, according to the Slovak Income Tax Act the income received by shareholders from acquiring new shares and income from exchange of the shares on merger transaction is not subject to income tax.

Authors: Dittmann Iwona
Published: January 2017

This paper presents the results of a comparison of the rates of return on specific open-end debt investment funds in Poland with the rates of return on bank deposits, in light of different time horizons. A comparative analysis was conducted based on the quartiles of the empirical distributions of the rates of return on selected funds and bank deposits. The empirical distributions were obtained using a moving window of observation. The results were largely influenced by very high interest rates on bank deposits in Poland in the years 1995–2001 (in the case of the oldest funds), and by the boom in the bond market in the years 2011–2012 (for the youngest funds). The investment horizon turned out to be significant. The best and worst funds were identified.

Changes in transboundary water resources management in Central Asia brought the river pollution issue even more up to date than runoff and water distribution problems. This survey demonstrates that the analysis of river flow dynamics. Their water consumption and pollution makes it possible to prioritize these aspects of water management.

As in the case of the Tobol-Torgay basin in Kazakhstan it was shown that for this type of basins. anthropogenic pollution remains a priority factor in transboundary water management. The Tobol River a tributary of the Ob and the Irtysh rivers belongs to the Kara Sea basin and is situated in the territory of Kazakhstan and Russia. Tobol-Torgay River basin located within borders of Kostanay region of Kazakhstan covers the upper reaches of the Tobol River and its tributaries. It has been determined that the water quality of the rivers in the region is stable for the decade under study and its formation remains due to natural factors. The priority contaminants in the basin are heavy metals and organic matter introduced by anthropogenic sources.

Introduction
Authors: Aliverti Ana , Bosworth Mary
Published: January 2017

As unprecedented levels of human mobility continue to define our era, criminal justice institutions in countries around the world are increasingly shaped by mass migration and its control. This collection brings together legal scholars from Europe and the United States to consider the implications of the attendant changes on the exercise of state penal power and those subject to it. The contributions in this special issue are united by a shared set of questions about the salience of citizenship for contemporary criminal justice policies and practices. They are specifically concerned with questions of fair and equal treatment, the changing configurations of state sovereignty, and the significance of migration on criminal justice policies and practices. Collectively, the articles show how, in grappling with mass mobility and diversity, states are devising novel forms of control, many of which erode basic criminal justice principles and reinforce existing social hierarchies.

Published: January 2017

Mycobacterium tuberculosis (Mtb) can persist in the human host in a latent state for decades, in part because it has the ability to withstand numerous stresses imposed by host immunity. Prior studies have established the essentiality of the periplasmic protease MarP for Mtb to survive in acidified phagosomes and establish and maintain infection in mice. However, the proteolytic substrates of MarP that mediate these phenotypes were unknown. Here, we used biochemical methods coupled with supravital chemical probes that facilitate imaging of nascent peptidoglycan to demonstrate that during acid stress MarP cleaves the peptidoglycan hydrolase RipA, a process required for RipA's activation. Failure of RipA processing in MarP‐deficient cells leads to cell elongation and chain formation, a hallmark of progeny cell separation arrest. Our results suggest that sustaining peptidoglycan hydrolysis, a process required for cell elongation, separation of progeny cells, and cell wall homeostasis in growing cells, may also be essential for Mtb's survival in acidic conditions.
Leptin stimulates bone formation in ob/ob mice at doses having minimal impact on energy metabolism
Authors: Philbrick Kenneth A , Wong Carmen P , Branscum Adam J , Turner Russell T , Iwaniec Urszula T
Published: January 2017

Leptin, the protein product of the ob gene, is essential for normal bone growth, maturation and turnover. Peripheral actions of leptin occur at lower serum levels of the hormone than central actions because entry of leptin into the central nervous system (CNS) is limited due to its saturable transport across the blood–brain barrier (BBB). We performed a study in mice to model the impact of leptin production associated with different levels of adiposity on bone formation and compared the response with well-established centrally mediated actions of the hormone on energy metabolism. Leptin was infused (0, 4, 12, 40, 140 or 400 ng/h) for 12 days into 6-week-old female ob/ob mice (n = 8/group) using sc-implanted osmotic pumps. Treatment resulted in a dose-associated increase in serum leptin. Bone formation parameters were increased at EC50 infusion rates of 7–17 ng/h, whereas higher levels (EC50, 40–80 ng/h) were required to similarly influence indices of energy metabolism. We then analyzed gene expression in tibia and hypothalamus at dose rates of 0, 12 and 140 ng/h; the latter dose resulted in serum leptin levels similar to WT mice. Infusion with 12 ng/h leptin increased the expression of genes associated with Jak/Stat signaling and bone formation in tibia with minimal effect on Jak/Stat signaling and neurotransmitters in hypothalamus. The results suggest that leptin acts peripherally to couple bone acquisition to energy availability and that limited transport across the BBB insures that the growth-promoting actions of peripheral leptin are not curtailed by the hormone’s CNS-mediated anorexigenic actions.

In paper the features of energy transformation processes in activated with erbium ions laser materials based on optical transitions in 4f shell of Er3+ ionwere discussed. Methods of excitation of the luminescence in chalcogenide glasses doped with Er3+ ions were described and found how its intensity depends on concentration of the ions. Up-conversion and cross-relaxation play an important role in the transformation of excitations in erbium-doped materials. In cross-relaxation the energy of one center can be nonradiatively transferred to another center or divided between the two centers, while in the up-conversion, however, energy of several centers summed up in one center, bringing it acts as an additional channel of luminescence quenching, or as a way of pumping of the higher energy levels. To improve the efficiency of optical excitation of many laser materials doped with erbium ions the sensitization with ytterbium ions that have intense absorption band in the range of ~0.9-1 µm with "effective" width of about 1000 cm-1 as well a channel of the efficient nonradiative excitation energy transfer to Er3+ ions is widely used.

Published: January 2017

Advanced integrated logic circuits on GaAs are mainly based on the using of n-channel field-effect transistors with gate Schottky (MESFET). To create the complementary MESFET integrated circuits the main problem is quite small Schottky barrier height (< 0,5 eV) on p-type gallium arsenide. One way to solve this problem is to use a nitride or silicide tungsten compounds to form gates given the thickness and composition.

This paper highlights the features of the formation of complementary high-speed logic circuits on the p-GaAs with self-aligned gate based on nitride or silicide of tungsten obtained by reduced pressure horizontal reactor "Izotron 4" and of RF magnetron sputtering equipment "Oratorio-5." This technology can also be used to form a Schottky contact to n- channel MESFET.

Since the manufacturing process of MESFET self-aligned gate provides using refractory gate material as a mask for the multiply ion implantation, the Schottky contact must withstand subsequent high-temperature heat treatment required to activate implanted impurities. In this connection, the action of high-temperature photonic and resistive heating on the barrier height of Schottky contact formed by nitride (silicide) tungsten (WNx, WSix) GaAs was also studied.

Authors: Rozantsev G.M.
Published: January 2017

The method of mathematical modeling (program CLINP 2.1, Newton's method) on the basis of the pH-potentiometric titration data allowed to calculate concentration constants of isopolytungstate anions (IPTA) formation at different ionic forces (I = 0,01 ‑ 0,5 M). Thermodynamic constants of IPTA formation were obtained as a result of processing by Pitzer method using the concentration constans. The standard Gibbs energy of isopolytungstate anions formation were calculated. The last ones allowed to estimate the thermodynamic probability of the reactions, that can be used in the synthesis of salts containing these anions. The structure of known isopolytungstates can be built from the combination of such fragments: WO, W2O, W3O, W4O and W5O. The calculation of standard Gibbs energy of these fragments formation allowed to characterize the structure of hexatungstate-anion W6O20(OH)26-, which does not contain three terminal oxygen atoms. Such approach of using Gibbs energy of building blocks was recommended for prediction of equilibrium constants values in the mathematical modeling.

Published: January 2017

The comparative investigation of two chemical polishing methods as applied to GaAs substrates is carried out. In both cases the equal etchant Br2+HBr was used. The comparison of etching rates and of surface morphology is carried out. It is revealed that numerous etching pits arise during chemo-dynamical polishing of GaAs (111) В samples but not arise during non-contact chemo-mechanical polishing of the same samples. Besides, last method allows to raise appreciably etching rate as compared with the method of chemo-dynamical polishing. That is, the same etchant behaves as selective or polishing depending on method of polishing. On the basis of worked out model of substrate surface etching near line defect the simulating of etching pit arising is carried out. The results of simulation are consistent with the idea that there are two competing ways of GaAs etching in the etchant Br2+HBr .

Education should be considered as one of the mechanisms for governments and nations to succeed in a post-conflict process. The purpose of this Review Article is twofold: to explain the importance of education in a post-conflict setting, and to describe a few strategies that post-conflict societies have implemented. In terms of research design, a multiple case study approach has been implemented. The paper reviews a unique topic with specific reference to education plans implemented in post-conflict societies such as Liberia, Sierra Leone, and South Africa. Each of them has experienced violent conflicts and has used education as a tool to succeed in their post-conflict process. In sum, there are several educational programs that involve children, young people, survivors, parents, teachers, and local communities as well as curriculums focused on teaching of cultural values and technical skills to improve the quality of life in a post-conflict setting.
Evolución conceptual e importancia de la andragogía para la optimización del alcance de los programas y proyectos académicos universitarios de desarrollo rural
Authors: Azofeifa-Bolaños José Bernal
Published: January 2017

This study was carried out with the objective of describing the evolution and importance of andragogical processes in the search of rural profiles committed to the university work in the development and implementation of programs and projects. Among its main contributions, the importance of knowing and teaching processes applied strictly for adults by university coordinators of programs and projects stands out. The relevance of applying this kind of knowledge will allow efficient use of institutional financial resources, particularly for the real commitment of the rural adult community towards the implementation of field activities and accomplishing, in a shorter term, the expected academic achievement. A successful project experience is described in which some andragogical strategies were applied through extension, and which produced a better participation and engagement from rural people with the projects developed by the University. Consequently, applicability of these concepts in the programs and projects of rural development promoted through universities must lay the foundation for regional rural development strategies with the ultimate goal of finding ways to improve the quality of life of people in particular scenarios.

We studied the influence of a different level of a calcium and phosphorus in mixed fodders on morphological and biochemical indexes of a blood of Japanese quail. We selected 240 quails, which were divided into 6 equal groups - control and 5 experimental. Experimental quails were contained in six-fodders cell battery, each cell was 60x40x20 cm and contained of 20 birds (15 females and 5 males). At the beginning of the experiment the experimental quails had similar body weight indicators that were the same in the end of our research. When we fed quails with different levels of calcium and phosphorus wew registered that calcium, magnesium, total protein and alkaline phosphatase activity in their blood was within physiological norm. We identified no significant differences in these indicators. It should be noted that the highest content of phosphorus in the quail blood was observed in female birds of 6th experimental group, which exceeded by 23.1% the values in quails of control group with calcium content of 4.0% and phosphorus of 1.4% (P <0.05). The introduction of different level of a calcium and phosphorus were not significantly affect the blood erythrocytes, leukocytes, and hemoglobin. The ratio of segmented rods, eosinophils, lymphocytes and monocytes in the blood of experimental birds was within the physiological norm of fluctutations. In content, there was a slight deviation (within 1%) was not statistically significant in the blood of the bird experimental and control groups, eosinophils and monocytes. The lymphocyte content was below 8.3% in the blood of all experimental bird groups. It is revealed that a level of a calcium of 4.0 % and phosphorus of 0.8, 1,1, and 1,4 % in rations of quails, promotes rising of a calcium level in skeleton of female quails and does not influence significantly the morphological and biochemical blood indices.

The research objective. To research the effective action of probiotic (feed additive) ‘Probiol’ on the live weight, the growth, and slaughter traits of cross Ross-308 broiler chickens. Results. The live weight of broiler chickens fed with probiotic (feed additive) ‘Probiol’ was 2658.2 g (by 14.4% larger than control). Moreover, the survival rate of broiler chickens in experimental group increased by 4%. It was observed that average daily growth of broiler chickens from experimental group was higher by 14.7% and absolute growth was higher by 14.6% than in control group. It was observed that the feed consumption was 1.82 kg per 1 kg of chicken growth in control group and 1.68 in the experimental group (smaller by 9.6%). It was proved that usage of probiotic ‘Probiol’ caused the increasing of ante live weight by 15.5%, the undressed carcass by 15.6%, half-dressed carcass by 16.8%, and dressed carcass by 7.9 % compared to control group. The using of probiotic also increased the weight of pectoral muscles by 17.7% and femoral muscles by 13.0% of the chickens in experimental group; this was also facilitated the increasing of the weight of chicken glandular stomach by 35.0%.

The assessment of the information value of ecogeographical predictors based on remote sensing data from satellites to reflect features of the ecological niche of the Swan-mute Cygnus up (Gmelina, 1803) in wintering within the Gulf Sivash have been presented. Two groups predictors of ecogeographical landscape data have been considered. The first group is assigned digital elevation model and its derivatives. The second set of classified vegetation indices obtained from Landsat 8 image. Ecological niche has been described using ENFA-procedure. The procedure of random distribution of the pseudo-absent points which range from the presence points restricted by some distance has been applied to assess the role of scale in ecological niche. Ecological niche of Swan mute has been shown to be described in terms of landscape ecogeographical variables. The properties of the ecological niche of the Swan-mute have been found to be depends upon the scale of its consideration. Under various boundary ranges we can get an entirely different, but statistically valid, assess the structure of the ecological niche of the Swan-mute based landscape ecogeographical predictors. The role of the various ecogeographical predictors depending on the scale can vary greatly.

The set of performance speed permeability experimental versions mounds of tehnozems designed to search for the best technological solutions for reclamation of disturbed mountain design land within the Nikopol manganese ore Basin have been discussed in the present article such as pedozems (tehnozems formed using bulk humus soil), litozems (formed only rocks without humus bulk soil): sod-litogenic soils to gray-green clay, the reddish-brown clays and loams on loess-like clays. The speed of tehnozems water permeability has been explored by the conventional method. Research conducted on test plots of land reclamation Dnipropetrovsk State Agrarian and Economic University. Research facilities have been 57 models with various options mound tehnozems ground. Based on research built graphics dynamics permeability. The data indicate that the models studied mound soil infiltration process of transition to a filtration significantly prolonged the time. Even in a stable phase permeability for tehnozems observable characteristic combination of filtration and infiltration processes. It is shown that the design soil-like body in the zero-point of its existence, the dynamics and trajectory of soil formation. The study of the dynamics of tidying up water from the soil surface is highly informative tool for evaluating the properties of the soil body without violations. The resulting dynamic curves along with high resolution differential is environmentally relevant, that reflect the properties of the soil as the habitat of living organisms. Differential capacity curves tidying water appears that there are significant differences between the movement of moisture in soil in the studied sites, depending on their structure. For ordinary chernozems permeability characteristic features of the process is monotonic dynamic speed limit tidying water and that clearly differs between phase infiltration and filtration. Switch phase filtration is the first experiment. For the studied models tehnozems the speed permeability characterized by a significant variation with relatively monotonous trend, which is the reduced rate of tidying water and eventually reach a certain steady state. Such deviations from the general trend manifest itself in the form of high speed flash permeability observed at regular intervals. These intervals are specific to each type of construction tehnozems.
