Flexible Adjustment of Hotel Facilities to Market Demand
Authors: Milwicz R. , Nowotarski P. 
Published: August 2016

Abstract Accommodation tourist industry is characterized by high variability. For this category of services not only the location is crucial- that does not change, but also the standard, prices and seasonality of services. In the recent years, leisure centers performing functions only during the summer time have seen the possibility to extend their activities beyond the summer months. The reasons for this are the local investments requiring qualified staff which comes from different parts of the country, Europe and the world while creating demand for accommodations. To meet the possible demand needs and to adapt to cold season, performing thermo-modernization works is necessary. In order to find the best solution and answer those needs, analysis of the profitability of the investments in a chosen holiday resort was carried out. The article presents the results of the analysis based on the payback period, LCC analysis and assessment of the investments risk.
Identification of Risk Factors of Development and Operation of Roads in the Light of Surveying Work
Authors: Skorupka D. , Kowacka M. 
Published: August 2016

Abstract This article aims to identify potential risk factors affecting the implementation and synchronisation of surveying and construction works during building and operation of roads. The task was executed on the basis of literature studies and experience. The article is an introduction to the research that has been conducted by the authors on the reasonably precise index of factors which one may deal with during the implementation of facilities of this type. The raised issue is crucial for financial and time reasons, but what is important in the roads construction - also for social ones, as prolonged traffic disruption adversely affects the environment.
Knowledge Discovery in Data in Construction Projects
Authors: Szelka J. , Wrona Z. 
Published: August 2016

Abstract
Decision-making processes, including the ones related to ill-structured problems, are of considerable significance in the area of construction projects. Computer-aided inference under such conditions requires the employment of specific methods and tools (non-algorithmic ones), the best recognized and successfully used in practice represented by expert systems. The knowledge indispensable for such systems to perform inference is most frequently acquired directly from experts (through a dialogue: a domain expert - a knowledge engineer) and from various source documents. Little is known, however, about the possibility of automating knowledge acquisition in this area and as a result, in practice it is scarcely ever used. It has to be noted that in numerous areas of management more and more attention is paid to the issue of acquiring knowledge from available data. What is known and successfully employed in the practice of aiding the decision-making is the different methods and tools. The paper attempts to select methods for knowledge discovery in data and presents possible ways of representing the acquired knowledge as well as sample tools (including programming ones), allowing for the use of this knowledge in the area under consideration.
Effect of nanofluid concentration on two-phase thermosyphon heat exchanger performance
Authors: Cieśliński Janusz T. 
Published: August 2016

Abstract
An approach - relaying on application of nanofluid as a working fluid, to improve performance of the two-phase thermosyphon heat exchanger (TPTHEx) has been proposed. The prototype heat exchanger consists of two horizontal cylindrical vessels connected by two risers and a downcomer. Tube bundles placed in the lower and upper cylinders work as an evaporator and a condenser, respectively. Distilled water and nanofluid water-Al2O3 solution were used as working fluids. Nanoparticles were tested at the concentration of 0.01% and 0.1% by weight. A modified Peclet equation and Wilson method were used to estimate the overall heat transfer coefficient of the tested TPTHEx. The obtained results indicate better performance of the TPTHEx with nanofluids as working fluid compared to distilled water, independent of nanoparticle concentration tested. However, increase in nanoparticle concentration results in overall heat transfer coefficient decrease of the TPTHEx examined. It has been observed that, independent of nanoparticle concentration tested, decrease in operating pressure results in evaporation heat transfer coefficient increase.
Review of numerical models of cavitating flows with the use of the homogeneous approach
Authors: Niedźwiedzka Agnieszka , Schnerr Günter H. , Sobieski Wojciech 
Published: August 2016

Abstract
The focus of research works on cavitation has changed since the 1960s; the behaviour of a single bubble is no more the area of interest for most scientists. Its place was taken by the cavitating flow considered as a whole. Many numerical models of cavitating flows came into being within the space of the last fifty years. They can be divided into two groups: multi-fluid and homogeneous (i.e., single-fluid) models. The group of homogenous models contains two subgroups: models based on transport equation and pressure based models. Several works tried to order particular approaches and presented short reviews of selected studies. However, these classifications are too rough to be treated as sufficiently accurate. The aim of this paper is to present the development paths of numerical investigations of cavitating flows with the use of homogeneous approach in order of publication year and with relatively detailed description. Each of the presented model is accompanied by examples of the application area. This review focuses not only on the list of the most significant existing models to predict sheet and cloud cavitation, but also on presenting their advantages and disadvantages. Moreover, it shows the reasons which inspired present authors to look for new ways of more accurate numerical predictions and dimensions of cavitation. The article includes also the division of source terms of presented models based on the transport equation with the use of standardized symbols.
Prediction of flow boiling heat transfer coefficient for carbon dioxide in minichannels and conventional channels
Authors: Mikielewicz Dariusz , Jakubowska Blanka 
Published: August 2016

AbstractIn the paper presented are the results of calculations using authors own model to predict heat transfer coefficient during flow boiling of carbon dioxide. The experimental data from various researches were collected. Calculations were conducted for a full range of quality variation and a wide range of mass velocity. The aim of the study was to test the sensitivity of the in-house model. The results show the importance of taking into account the surface tension as the parameter exhibiting its importance in case of the flow in minichannels as well as the influence of reduced pressure. The calculations were accomplished to test the sensitivity of the heat transfer model with respect to selection of the appropriate two-phase flow multiplier, which is one of the elements of the heat transfer model. For that purpose correlations due to Müller-Steinhagen and Heck as well as the one due to Friedel were considered. Obtained results show a good consistency with experimental results, however the selection of two-phase flow multiplier does not significantly influence the consistency of calculations.

Published: August 2016

Abstract
The article presents an analysis of the concept of novelty of artistic forms and its visual expressions in contemporary Lithuanian architecture. It is stated that the novelty is virtually manifested through utopian visions of the new world and their metamorphoses, and is made relevant by the method of experiment. Based on examples of Western European architectural utopias and experiments, the article suggests the formulated indicators of novelty, which are reflected in artistic forms of contemporary Lithuanian architecture. The aim of the research is to reveal the concept of novelty linking it with transformation and utopia, and illustrating it with the objects of contemporary Lithuanian architecture.

Abstraction of Meaningful Symbolized Objects
Authors: Kollár Ján , Sičák Michal , Spišiak Milan 
Published: August 2016

Abstract
We describe the notion of abstraction and conceptualization
of information obtained by symbolization
of letters. We are able to recognize already observed information
with those abstracted concepts. Further more,
we are also able to recognize similar meaningful objects.
Similarities identification is based on a repetition in the
structure of information symbolized as a regular language
string. We discuss approaches of repetition identification,
i.e., longest repeating non-overlapping subsequence and
longest common subsequence. Then we apply those approaches
to the symbolized letters, thus obtaining abstracted
information in the form of concepts.
A descriptive study for corrosion control of low-alloy steel by Aloe vera extract in acidic medium
Authors: Dahiya Shefali , Lata Suman , Kumar Parmod , Kumar Rajeev 
Published: August 2016

Abstract
Methanol extract of Aloe vera leaves (AE) as a green inhibitor for controlling corrosion of low-alloy steel (mild steel) in 0.5 m HCl solution was studied using gravimetric analysis, potentiostatic polarization measurements, electrochemical impedance spectroscopy and quantum analysis. The results obtained revealed that AE has fairly good inhibiting properties against corrosion of mild steel in 0.5 m HCl solution, with efficiency >97%. Also, the inhibition was mixed type that follows the Langmuir adsorption isotherm. The value of ΔG reveals that AE inhibits the corrosion rate via physical type adsorption on the mild steel surface which is further supported by Dubinin-Radushkevich isotherm.

Canons and Contemporary Danish Literature
Authors: Mai Anne-Marie 
Published: August 2016

Abstract
This article deals with recent Danish literature in the light of the discussion about canons occasioned by the publication of the two ministerial canons: Undervisningskanon (Educational Canon, 2004) and Kulturkanon (Cultural Canon, 2006). The article argues that recent Danish literature challenges traditional work categories and the concept of the author on which the two canons are based, and discusses which works and texts in recent Danish literature ought to belong to a future canon.
Saamskie teatry
Authors: Sibińska Maria 
Published: August 2016

Abstract
Institutional theatres in Sapmi have a relatively brief history but they are based upon traditional cultural heritage (the yoik, the art of storytelling, shamanistic seances). At the same time they are open to impulses from other cultures and theatrical traditions (European and non-European) that contribute to the distinct features of Samic theatrical performance when it comes to texts, the aesthetics of performance, and acting traditions. The article outlines the Samic theatre landscape in general and then proceeds to focus on the multicultural aspects of "Ridn'oaivi ja nieguid oaidni", a performance by the Beaivváš Sami Teáhter. The article also calls attention to the problematic nature of the concept "cultural dialogue" in a situation when the borderlines between individual cultures are no longer obvious, and when it is no longer easy to identify the partners in a dialogue unequivocally.

Wood Pyrolysis Using Aspen Plus Simulation and Industrially Applicable Model
Authors: Lestinsky Pavel , Palit Aloy 
Published: August 2016

Abstract
Over the past decades, a great deal of experimental work has been carried out on the development of pyrolysis processes for wood and waste materials. Pyrolysis is an important phenomenon in thermal treatment of wood, therefore, the successful modelling of pyrolysis to predict the rate of volatile evolution is also of great importance. Pyrolysis experiments of waste spruce sawdust were carried out. During the experiment, gaseous products were analysed to determine a change in the gas composition with increasing temperature. Furthermore, the model of pyrolysis was created using Aspen Plus software. Aspects of pyrolysis are discussed with a description of how various temperatures affect the overall reaction rate and the yield of volatile components. The pyrolysis Aspen plus model was compared with the experimental data. It was discovered that the Aspen Plus model, being used by several authors, is not good enough for pyrolysis process description, but it can be used for gasification modelling.

Published: August 2016

Abstract
The paper presents the results of the model of anaerobic co-fermentation of cattle slurry with biscuit waste. It was confirmed that the waste from the food industry is a valuable biogas substrate. The highest specific production of methane (0.49 mN3·kgVS-1) was achieved in the co-fermentation of 20 wt% biscuit waste with cattle slurry. The feed mixture contained 22 wt% of total solids. The biscuit waste has the specific production of biogas 0.66 mN 3·kg-1 and the specific production of methane 0.38 mN 3·kg-1.
Effect of summer fire on cursorial spider (Aranei) and beetle (Coleoptera) assemblages in meadow steppes of Central European Russia
Authors: Polchaninova Nina , Tsurikov Mikhail , Atemasov Andrey 
Published: August 2016

Abstract
Fire is an important structuring force for grassland ecosystems. Despite increased incidents of fire in European steppes, their impact on arthropod communities is still poorly studied. We assessed short-term changes in cursorial beetle and spider assemblages after a summer fire in the meadow steppe in Central European Russia. The responses of spider and beetle assemblages to the fire event were different. In the first post-fire year, the same beetle species dominated burnt and unburnt plots, the alpha-diversity of beetle assemblages was similar, and there were no pronounced changes in the proportions of trophic groups. Beetle species richness and activity density increased in the second post-fire year, while that of the spiders decreased. The spider alpha-diversity was lowest in the first post-fire year, and the main dominants were pioneer species. In the second year, the differences in spider species composition and activity density diminished. The main conclusion of our study is that the large-scale intensive summer fire caused no profound changes in cursorial beetle and spider assemblages of this steppe plot. Mitigation of the fire effect is explained by the small plot area, its location at the edge of the fire site and the presence of adjacent undisturbed habitats with herbaceous vegetation.
Ecology and Conservation of Steppes and Semi-Natural Grasslands
Authors: Valkó Orsolya , Zmihorski Michal , Biurrun Idoia , Loos Jacqueline , Labadessa Rocco , Venn Stephen 
Published: August 2016

Abstract
Palaearctic grasslands encompass a diverse variety of habitats, many of high nature value and vulnerability. The main challenges are climate-change, land-use change, agricultural intensification and abandonment. Many measures are in place to address these challenges, through restoration and appropriate management, though more work is necessary. We present eight studies from China/Germany, Greece, Kazakhstan, Russia and Ukraine. The papers cover a wide range of grassland and steppe habitats and cover vegetation ecology, syntaxonomy and zoology. We also conducted a systematic search on steppe and grassland diversity. The greatest number of studies was from China, followed by Germany and England. We conclude that the amount of research being carried out on Eurasian grasslands is inadequate considering their high levels of biodiversity and vulnerability. We hope to encourage readers to address current major challenges, such as how to manage grasslands for the benefit of diverse taxa, to ensure that conservation initiatives concentrate on sites where there is good potential for success and for the generation of realistic and viable conservation strategies.
Latino linguistic repertoires in an intensely-segregated Black and Latina/o high school: Is this super-diversity?
Authors: Martinez Danny C. 
Published: August 2016

AbstractThis article explores the communicative interactions of one Latino youth, Lorenzo, in an English Language Arts classroom located in an intensely-segregated Black and Latino urban community. While the larger city in which this school is located is known for its diverse cosmopolitan population characteristic of super-diversity, I argue that Lorenzo’s language practices index his socialization in contact zones shaped by Black and Latina/o cultural and linguistic practices. While sociolinguistic perspectives on super-diversity might offer an explanation for the repertoires of languages uttered by Lorenzo and his Black and Latina/o peers, the language practices explored are reflective of the cultural historical experiences of Lorenzo’s intensely-segregated community which have been practiced prior to any conceptualization of super-diversity. Drawing on super-diversity research, language ideological inquiry and language crossing and sharing scholarship, this article calls for further attention to the cultural historical past of Black and Latina/o communities in future discussions of super-diversity in the U.S.
What practices and ideologies support small-scale multilingualism? A case study of Warruwi Community, northern Australia
Authors: Singer Ruth , Harris Salome 
Published: August 2016

AbstractAt Warruwi, a remote Australian Indigenous community, people use a range of Indigenous languages on a daily basis. Adults speak three to eight Indigenous languages and these high levels of multilingualism are out of step with current trends which see most Australian Indigenous communities shifting to a single variety be it a variety of English, a contact variety or a traditional Indigenous language. The three Indigenous languages most widely spoken at Warruwi are quite dissimilar as they belong to separate language families. This article discusses three characteristics of language use at Warruwi that are likely to play a role in supporting the levels of multilingualism found there: the diversity of individual linguistic repertoires, receptive multilingual practices whereby interlocutors address one another in different languages and language ideologies that are quite different to those found elsewhere. Characteristics of multilingualism at Warruwi are compared with those reported for other communities with small-scale multilingualism. Francois’ (
Rethinking Boudon’s Cognitive Rationality in the Light of Mises’ Apriorism and Gadamer’s Hermeneutics
Authors: Di Iorio Francesco , Di Nuoscio Enzo 
Published: August 2016

Abstract
The purpose of this article is to show that Boudon’s explanation of action in terms of “good reasons” can be philosophically enriched by merging his methodological perspective with Mises’ praxeology and Gadamer’s hermeneutics. In order to develop our goal of merging Boudon’s approach with Mises’ and Gadamer’s, we will focus on two points. The first is the identification of the invariable structure of human action. Unlike Boudon, we suggest that the best way to establish this invariable structure, which makes the explanation of action possible, is not to refer to the controversial concept of “human nature,” but rather to use Mises’ praxeological analysis of the invariable logic which all actions have in common. The second point analyzed in this article is the temporal and cultural dimension of the interpretative process which individuals elaborate to develop their reasons. This point, which is related to hermeneutical philosophy and is not investigated in detail by Boudon, is largely discussed by Gadamer. In our opinion, merging Gadamer’s description of the interpretative process – a process that Gadamer calls “hermeneutical circle” – and Boudon’s sociology of “good reasons” is useful because, unlike Boudon, Gadamer clarifies the epistemological nature of the interpretative process as well as the reasons why this process – which is a trial and error process – allows us to understand the actions of people who belong to different cultures.
Environmental Monitoring Supported by Aerial Photography – a Case Study of the Burnt Down Bugac Juniper Forest, Hungary

Published: August 2016

Abstract
Wildfire poses a serious risk in several regions of the world threatening urban, agricultural areas and natural ecosystems as well. Nature conservation has important role to be prepared for the management of postfire environmental degradation and restoration for protected areas preserving valuable ecosystems. The improving temporal and spatial resolution of remote sensing and GIS methods significantly contributes to map the changes for accelerating management steps of restoration. In this study a severe wildfire and its impacts were assessed in case of a protected area of the Kiskunság National Park in Hungary, which was partly burnt down in 2012. The aim of this research was to efficiently and accurately assess the damages and to plan and execute the restoration works using remote sensing tools. Aerial data collection was performed one month, and one year after the fire. In 2014 the regenerated vegetation was surveyed and mapped in the field. Using the aerial photographs and the field data, the degree and extent of the fire damages, the types and the state of the vegetation and the presence and proportion of the invasive species were determined. Semi-automatic methods were used for the classification of completely, partially damaged and undamaged areas. Based on the results, the reforestation of the burnt area is suggested to prevent the overspreading of white poplar against common junipers and to clean the area from the most frequent invasive species. To monitor the regeneration of the vegetation and the spreading of the invasive species, further aerial photography and field campaigns are planned.
