Inlet effects on roll-wave development in shallow turbulent open-channel flows
Authors: Campomaggiore Francesca , Di Cristo Cristiana , Iervolino Michele , Vacca Andrea 
Published: January 2016

Abstract
The present work investigates the effect of the flow profile induced by an inlet condition on the roll-wave evolution in turbulent clear-water flows. The study employs theoretical and numerical analyses. Firstly, the influence of the inlet condition on the spatial evolution of a single perturbation in a hypercritical flow is examined through the expansion near a wavefront analysis. The results show that an accelerated unperturbed profile reduces the disturbance spatial growth. A decelerated profile causes an increase. The effect of the flow profile on the spatial evolution of roll-wave trains is then numerically investigated solving the Saint Venant equations with a second-order Runge-Kutta Total Variation Diminishing (TVD) Finite Volume scheme. The numerical simulations comply with the analytical results for the initial and transition phases of the roll-wave development. The unperturbed profile influences even the roll-waves statistical characteristics in the final stage, with a more evident effect in case of accelerated profiles. The influence of the flow profile should be therefore accounted for in the formulation of predictive criteria for roll-waves appearance based on the estimation of the disturbance spatial growth rate.

Published: January 2016

Abstract
In Tunisia especially in the Medjerda watershed the recurring of floods becoming more remarkable. In order to limit this risk, several studies were performed to examine the Medjerda hydrodynamic. The analysis of results showed that the recurrences of floods at the Medjerda watershed is strongly related to the sediment transport phenomena. Initially, a one dimensional modelling was conducted in order to determine the sediment transport rate, and to visualize the river morphological changes during major floods. In continuity of this work, we will consider a two-dimensional model for predicting the amounts of materials transported by the Medjerda River. The goal is to visualize the Medjerda behaviour during extreme events and morphological changes occurred following the passage of the spectacular flood of January 2003. As a conclusion for this study, a comparative analysis was performed between 1D and 2D models results. The objective of these comparisons is to visualize the benefits and limitations of tested models. The analysis of the results demonstrate that 2D model is able to calculate the flow variation, sediment transport rates, and river morphological changes during extreme events for complicated natural domains with high accuracy comparing with 1D Model.

Abstract
Knowledge on soil moisture is indispensable for a range of hydrological models, since it exerts a considerable influence on runoff conditions. Proper tools are nowadays applied in order to gain in-sight into soil moisture status, especially of uppermost soil layers, which are prone to weather changes and land use practices. In order to establish relationships between meteorological conditions and topsoil moisture, a simple model would be required, characterized by low computational effort, simple structure and low number of identified and calibrated parameters. We demonstrated, that existing model for shallow soils, considering mass exchange between two layers (the upper and the lower), as well as with the atmosphere and subsoil, worked well for sandy loam with deep ground water table in Warsaw conurbation. GLUE (Generalized Likelihood Uncertainty Estimation) linked with GSA (Global Sensitivity Analysis) provided for final determination of parameter values and model confidence ranges. Including the uncertainty in a model structure, caused that the median soil moisture solution of the GLUE was shifted from the one optimal in deterministic sense. From the point of view of practical model application, the main shortcoming were the underestimated water exchange rates between the lower soil layer (ranging from the depth of 0.1 to 0.2 m below ground level) and subsoil. General model quality was found to be satisfactory and promising for its utilization for establishing measures to regain retention in urbanized conditions.
Substratum morphology and significance during the Weichselian Odra ice lobe advance in northeast Germany and northwest Poland
Authors: Hermanowski Piotr 
Published: January 2016

Abstract
In the Polish Lowlands, three main ice lobes, referred to as Odra, Vistula and Mazury, formed during the Last Scandinavian Glaciation. These lobes protruded at least several kilometres beyond the main ice margin and it is believed that they represent terminal parts of the ice streams. Applied geostatistical analysis based on numerous geological data has allowed an approximate reconstruction of the Odra ice lobe substratum in the area of northwest Poland and northeast Germany. A spatial representation of the Odra lobe substratum clearly illustrates the adverse slope of the glacier bed, but also indicates areas morphologically prone to ice streaming. It is suggested that the ice took advantage of local topography that enabled advance out of the Baltic basin; consequently, the ice followed a topographic low which, in combination with favourable hydraulic conditions of its substratum, likely initiated ice streaming.
The colour analysis method applied to homogeneous rocks
Authors: Halász Amadé , Halmai Ákos 
Published: January 2016

Abstract
Computer-aided colour analysis can facilitate cyclostratigraphic studies. Here we report on a case study involving the development of a digital colour analysis method for examination of the Boda Claystone Formation which is the most suitable in Hungary for the disposal of high-level radioactive waste. Rock type colours are reddish brown or brownish red, or any shade between brown and red. The method presented here could be used to differentiate similar colours and to identify gradual transitions between these; the latter are of great importance in a cyclostratigraphic analysis of the succession. Geophysical well-logging has demonstrated the existence of characteristic cyclic units, as detected by colour and natural gamma. Based on our research, colour, natural gamma and lithology correlate well. For core Ib-4, these features reveal the presence of orderly cycles with thicknesses of roughly 0.64 to 13 metres. Once the core has been scanned, this is a time- and cost-effective method.

The installation of thermal energy storage system (TES) provides the optimisation of energy source, energy security supply, power plant operation and energy production flexibility. The aim of the present research is to evaluate the feasibility of thermal energy system installation at Riga TPP–2. The six modes were investigated: four for non-heating periods and two for heating periods. Different research methods were used: data statistic processing, data analysis, analogy, forecasting, financial method and correlation and regression method. In the end, the best mode was chosen – the increase of cogeneration unit efficiency during the summer.
Mathematical Modeling of Dual Layer Shell Type Recuperation System for Biogas Dehumidification
Authors: Gendelis S. , Timuhins A. , Laizans A. , Bandeniece L. 
Published: January 2016

Abstract
The main aim of the current paper is to create a mathematical model for dual layer shell type recuperation system, which allows reducing the heat losses from the biomass digester and water amount in the biogas without any additional mechanical or chemical components. The idea of this system is to reduce the temperature of the outflowing gas by creating two-layered counter-flow heat exchanger around the walls of biogas digester, thus increasing a thermal resistance and the gas temperature, resulting in a condensation on a colder surface. Complex mathematical model, including surface condensation, is developed for this type of biogas dehumidifier and the parameter study is carried out for a wide range of parameters. The model is reduced to 1D case to make numerical calculations faster. It is shown that latent heat of condensation is very important for the total heat balance and the condensation rate is highly dependent on insulation between layers and outside temperature. Modelling results allow finding optimal geometrical parameters for the known gas flow and predicting the condensation rate for different system setups and seasons.
Between Emotion and Intellect. On the Musical Language of Andrzej Panufnik (1914–1991)
Authors: Bolesławska-Lewandowska Beata 
Published: January 2016

Abstract
Andrzej Panufnik’s (1914-1991) key objective as a composer was to achieve a balance between emotion and intellect. The composer very often emphasised the role of the relation between these two elements in his works. This topic is the leitmotiv of texts about his own music left behind by the composer. From those texts, it is clearly evident that symmetry (and in later years also geometry) played a central role in the composer’s formal concepts. The impulse for the study of the possibility of using geometric shapes for the construction of musical forms came from his 1972 composition for the BBC television entitled Triangles - for three flutes and three cellos.
The geometricisation of the formal structures of Panufnik’s works (frequently represented by means of sophisticated diagrams included in the scores) was correlated with a systematic reduction of musical language, based from 1968 on the three-note intervallic cell of E-F-B. In the course of the composition, this unit was submitted to a succession of symmetrical processes, such as transpositions and mirror reflections, superimposed on one another both on the melodic and harmonic levels, which was responsible for the specific sound climate of Panufnik’s music. The fullest realisation of the composer’s systematic thinking based on the principles of geometry can be found in his Symphony No. 5 - Sinfonia di Sfere (1974), in which every element was submitted to the principles of geometric symmetry represented in a diagram based on the perfect geometric figure of a circle.
What is particularly important, this prominent constructivist current in Panufnik’s works always coexisted, as the composer himself claimed, with powerful emotional expression in his music. Did he manage to achieve the intended ideal balance between emotion and intellect in his music? Everyone can judge by themselves. This paper discusses the principal qualities of Andrzej Panufnik’s musical language.
Paweł Szymański’s Self-Analyses Reread
Authors: Naliwajek-Mazurek Katarzyna 
Published: January 2016

Abstract
The article is an attempt to present important categories of composer Paweł Szymański’s musical language, based on his self-analytical statements, which were in major part answers to musicologists’ questions. Luciano Berio pointed out why the situation of a composer who would like to address questions about his or her music is difficult - a lack of necessary detachment would be one of the reasons. A musicologist, on the other hand, is tempted to construct their own supposedly objective analytical view of a composer’s musical language. The dialogistic approach proposed by anthropological musicology may be a solution to these dilemmas. Other main topics mentioned in the article are related to the role of meta-concepts in Szymański’s musical language.
Paweł Hendrich’s Emergent Sound System
Authors: Hendrich Paweł , Stefański Krzysztof 
Published: January 2016

Abstract
Paweł Hendrich’s compositions can be compared to macrocrystals - solids composed of numerous small and identical elements, constructed in accordance with a strict pattern. Importantly, the same internal crystal structure can produce forms highly diversified with regard to external shape. Similarly, this composer’s works are very precisely structured already on the level of individual sounds, but this structure is only a tool for the creation of very clear musical macroforms. The idea of emergence - of new values resulting from the combination of simple elements - is of key importance to this composer.
The paper presents the principles of organising music material in the works of Paweł Hendrich. These are, among others: periodicity, multilayered structures, permutations and flexibility. These ideas are reflected in the musical work in many dimensions, both on the level of microand macro-structure. Their application exerts a major impact on the forms created by the composer.
With the development of his musical language, the composer transforms his initial material more and more radically. Simple elements and processes that underlie the construction of his works become progressively more and more difficult to reconstruct, largely due to the application of a computer in the composition process. A comprehensive look at Paweł Hendrich’s entire output of compositions proves that his work is emergent as a whole. With each new piece, a new element is added, but all of them form a coherent system. No wonder, then, that one of the composer’s works bears the telling title of Emergon.
Can analytical shading be art?
Authors: Siwek Jerzy , Wacławik Wojciech 
Published: January 2016

Abstract
Despite numerous theoretical and experimental studies of analytical relief shading, devised about half a century ago, its quality has not yet reached the excellence of traditional (manual) shading. The paper discusses its basic principles and the main factors affecting the quality of shading. It also stresses the crucial importance of the digital terrain model used as the basis for shading as well as the proper generalization of the relief. Experiments with shading modules of ArcGIS and Surfer, aiming to explore the functionality of algorithms they employ, have demonstrated significant similarity of the results. In conclusion, the authors attempt to answer the question posted in the title of the article. In their view, analytical shading is not art because shading algorithms are incapable of producing the visually beautiful effects that an experienced cartographer with artistic talents can create.
Maps in video games – range of applications
Authors: Chądzyńska Dominika , Gotlib Dariusz 
Published: January 2016

Abstract
The authors discuss the role of the map in various game genres, specifically video games. Presented examples illustrate widespread map usage in various ways and forms by the authors of games, both classic and video. The article takes a closer look at the classification and development of video games within the last few decades. Presently, video games use advanced geospatial models and data resources. Users are keen on a detailed representation of the real world. Game authors use advanced visualization technologies, which often are innovative and very attractive. Joint efforts of cartographers, geo-information specialists and game producers can bring interesting effects in the future. Although games are mainly made for entertainment, they are more frequently used for other purposes. There is a growing need for data reliability as well as for some effective means of transmission cartographic content. This opens up a new area of both scientific and implementation activity for cartographers. There is no universally accessible data on the role of cartographers in game production, but apparently it is quite limited at the moment. However, a wider application of cartographic methodology would have a positive effect on the development of games and, conversely, methods and technologies applied by game makers can influence the development of cartography.
The contemporary cartographic presentation of geographical names of objects lying on the border between Poland and the Czech Republic
Authors: Zych Maciej 
Published: January 2016

Abstract
The aim of this paper is the analysis of the names used on cartographic publications in Poland and the Czech Republic for transboundary geographical objects lying on the common boundary.
After the analysis of the Czech and Polish topographic maps that are available on the national geoportals, maps of the divisions into natural regions, and toponymic databases (Polish the National Register of Geographical Names, and Czech Geonames – the Database of geographic names of the Czech Republic) it was established that 360 named geographic objects lie on this boundary. This number includes: 123 hydronyms (names of rivers and other streams), 224 oronyms (139 names of summits, 22 names of mountain passes, 35 names of mountain ranges and ridges, 15 names of highlands, plateaus and uplands, 7 names of mountain basins, valleys and depressions, 3 names of lowlands, and 3 names of rocks), 9 names of forests, 1 name of mountain meadow (alp), and 3 names of tracks.
212 of these objects (59%) have names in both languages – Polish and Czech, however, in 99 cases (47% of objects that have name in both Polish and Czech languages) the Polish and Czech toponyms entirely do not correspond to each other. From the remaining objects 67 (18%) have only the Czech name, and 81 (23%) only the Polish name. In some natural regions, the limits of their ranges set by the Czech and Polish geographers vary widely, for example a single region on one side of the boundary corresponds to two or more regions on other side of the boundary. In other cases illustrations of incorrectness are more sophisticated, like the river that has different course according to the Czech or Polish maps (stream regarded as a main watercourse in one country, which has its own name, in another country is considered as a tributary one with a different name).
In the summary, it should be stated that in the large part of the Polish and Czech names of the geographical objects lying on the common boundary were drawn regardless of the names used in the neighboring country.

AbstractThe cholecystectomy procedure is the most routinely performed intervention in general surgery. The current international gold standard is via the laparoscopic approach. It is a safe, minimally-invasive procedure; however, it is associated with complications in 1% of cases.was to analyze patient feedback, by means of a survey, to determine how much knowledge patients possessed about their disease state and proposed surgical intervention, based primarily on information contained within the informed consent form developed by the Association of Polish Surgeons.This study involved the participation of 51 patients who underwent laparoscopic cholecystectomy, indicated by a diagnosis of gallstones, in the years 2014 and 2015.Despite having signed the informed consent form, there was considerable variation among the responses given to the survey by the 51 patients in this study. Some patients’ responses were tangential to the questions asked; many patients did not respond to any of the sub points.Given that this study is based on a small sample size of patients, it must be presumed that the process by which the patient declares his or her informed consent requires further consideration with respect to the means by which it is obtained. The authors of this study thus recommend that multimedia resources be harnessed as part of the process of obtaining the informed consent of patients prior to surgical intervention.
Abdominal Cavity Eventration Treated by Means of the „Open Abdomen” Technique Using the Negative Pressure Therapy System – Case Report and Literature Review
Authors: Trzeciak Piotr W. , Porzeżyńska Joanna , Ptasińska Karolina , Walczak Dominik A. 
Published: January 2016

AbstractWound dehiscence is a surgical complication in which the wound ruptures along the surgical suture with abdominal cavity bowel displacement. It is observed in 0.2-6% of operated patients. The extensive wound is a gateway for infection. Moreover, increased secretion of serous fluid induces a hygienic problem and may lead to secondary skin infections or bedsores. The negative pressure wound therapy (NPWT) system is an innovative therapeutic method. It perfectly executes the TIME strategy, receiving more and more recognition.The study presented a case of a 62-year old male patient after several consecutive wound dehiscence episodes who was primarily treated for rectal cancer by means of low anterior resection of the rectum. Due to acute respiratory insufficiency after several operations, wound necrosis with dehiscence was observed. Considering the high risk of perioperative death we abandoned surgical treatment and introduced conservative management using negative pressure wound therapy until the patient’s health improved. Literature regarding the above-mentioned issue was also reviewed.
New Coincident and Leading Indexes for the Lebanese Economy
Authors: Matta Samer 
Published: January 2016

AbstractWeak economic statistics in Lebanon impede economic analysis and decision making. This paper presents a new coincident index and a leading index for the Lebanese economy. A new methodology, based on the National Bureau of Economic Research–Conference Board approach, was used to construct these indexes. The indexes can be used as monthly proxies for the evolution of real gross domestic product with a relatively small time lag (four to five months). Notwithstanding the relatively small sample period, the results reveal promising statistical properties that should make these new indexes valuable coincident and leading (one-year ahead) indexes for analyzing the dynamics of the Lebanese economy. However, given limitations on the length of the gross domestic product time series in Lebanon, the accuracy of these indexes in tracking the business cycle of the Lebanese economy is expected to improve over time as more data points become available.
Two assumptions in legal discourse: To answer for self and to tell the truth
Authors: Petrilli Susan 
Published: January 2016

AbstractThe distinction between “initial meanings” and “additional meanings” which corresponds to that between “explicit meanings” and “implicit meanings,” evidences the complex stratification of signifying processes that subtend and orient discourse. Hidden meanings are implicit, mediated, indirect meanings, additional meanings. They are traceable not only in meanings determined by context, but also in meanings more independent from context. Initial, explicit meaning is meaning fixed by use and tradition, but all the same it is somehow conditioned by additional, implicit meaning, by hidden meaning. This paper focuses on two related assumptions, or hidden meanings that are no less than central to legal discourse: answering for self and telling the truth. Though the hidden meaning in these assumptions is not explicated, it in fact orientates legal discourse. Hidden meaning involves shared knowledge which is implied and taken for granted even though it is not voiced. The important question is: what is the collective, social conception of the subject that is tacitly implied in legal discourse, such to be capable of answering for self and of telling the truth?
