Comparison of Risk Index Estimating Methods on the Polish Financial Market
Authors: Janas Krzysztof 
Published: April 2019

Abstract
The purpose of this paper is to determine a practical approach of calculation of the systematic risk of companies in line with the CAPM model. By performing an analysis of the methodology used in practice of determining the beta and review of the literature on the subject the accounting rules that make the best possible impact on the change in the level of risk index are determined. In this work on the Polish financial market are also carried out simulations showing the impact of the change in assumptions on the final amount of beta. Based on the empirical results there is a recommendation formulated as to what method should determine beta for public companies using the CAPM model. These boundary conditions are also possible implementations of the proposed approach and possible desirable solutions, if minimum boundary conditions are not met. The defined scope for the use of the recommended method of calculating the risk index allows us to reduce the error probability of over-or underestimation of the value of the index.
The Plio–Pleistocene Demise of the East Carpathian Foreland Fluvial System and Arrival of the Paleo-Danube To The Black Sea
Authors: Matoshko Andrei , Matoshko Anton , de Leeuw Arjan 
Published: April 2019

Abstract
This paper studies the Porat Formation (Fm.), which was deposited along the NE margin of the Dacian Basin part of the East Carpathian foreland (ECF) during the Pliocene and Early Pleistocene. We use a review of stratigraphic data in combination with lithofacies and sedimentary architecture analysis to interpret the Porat Fm. as a large sandy alluvial basin infill with an aggradational structure, consisting of cyclic successions of shallow sandy high-energy braided rivers. Aggradation of the Porat Fan was governed by subsidence of the Dacian Basin, along with a northerly supply of water and sediment from the Carpathians. Along the southern margin of the area the fan entered the Reni–Izmail-Trough, which formed the periodically active gateway between the Black Sea and Dacian basins. Along this trough, the Porat Fm. is developed in a different facies, discerned as the Dolynske Member (Mb. 1), which accumulated in the channel of a large river interpreted as the paleo-Danube. According to mammal stratigraphy of the Porat Fm. this continental-scale river had reached the area by the Gelasian to early Calabrian. The Porat alluvial infill indicates a stable water supply from the Carpathians, which explains the ecologically mixed fauna in its deposits: moistened forested alluvial plain-valleys were present between the zonally semi-arid steppe interfluves. The Porat Fm. and the previously studied late Miocene Balta Fm. are key elements for further in-depth study of the terrestrial evolution (tectonic–sedimentary–relief) of the ECF and north-western Black Sea coastal regions.
Dasycladalean alga Furcoporella diplopora Pia (1918) from the type-locality (upper Paleocene–Eocene, Radstadt, Austria): new remarks and taxonomic implications
Authors: De Matteis Mario , Barattolo Filippo 
Published: April 2019

Abstract
The dasycladalean green alga Furcoporella diplopora Pia (1918) exhibits a peculiar structure comprising pairs of diverging and rather indistinct pores. Because of such structure, the genus Furcoporella has been a matter of debate. Currently, there is still no agreement on its taxonomic position within Dasycladales. This paper provides a re-description of the type-species F. diplopora Pia (1918), based on Pia’s type material from the upper Paleocene to Eocene reworked carbonates of Radstadt/Pongau, Austria. New observations carried out on this material allowed the acquisition of additional and more complete data on this quite neglected alga. Some morphological characteristics of the thallus, specifically of the laterals are discussed and a suite of potential taxonomic implications are evaluated. Finally, according to interpretations the genus Furcoporella is ascribed to the Family Triploporellaceae and more specifically it should be placed within the tribe Thyrsoporelleae.
Identification and molecular characterisation of bovine parainfluenza virus-3 and bovine respiratory syncytial virus - first report from Turkey
Authors: Timurkan Mehmet Ozkan , Aydin Hakan , Sait Ahmet 
Published: April 2019

Abstract

Introduction: Bovine parainfluenza virus-3 (BPIV3) and bovine respiratory syncytial virus (BRSV) are the cause of respiratory disease in cattle worldwide. With other pathogens, they cause bovine respiratory disease complex (BRDC) in ruminants. The aim of the study was the detection and molecular characterisation of BPIV3 and BRSV from nasal swabs and lung samples of cows in and around the Erzurum region of eastern Turkey. Material and Methods: In total, 155 samples were collected. Of animals used in the study 92 were males and 63 females. The age of the animals was between 9 months and 5 years, mean 1.4 years. Most males were in the fattening period and being raised in open sheds; females were in the lactating period and kept in free stall barns. All samples were tested for the presence of viral genes using RT-PCR. Gene-specific primers in a molecular method (RT-PCR) identified BRSV (fusion gene) and BPIV3 (matrix gene) strains at the genus level. Results: RNA from BRSV and BPIV3 was detected in two (1.29%) and three (1.93%) samples, respectively, one of each of which was sequenced and the sequences were aligned with reference virus strains. Phylogenetic analyses clustered the strains in genotype C/BPIV3 and subgroup III/BRSV. Conclusion: The results indicate that BRSV and BPIV3 contribute to bovine respiratory disease cases in Turkey. This is the first report on their detection and molecular characterisation in ruminants in Turkey.
Is there congruence in the spatial patterns of regions derived from scalar and vector geographical information?
Authors: Erlebach Martin , Halás Marián , Daniel Jan , Klapka Pavel 
Published: April 2019

Abstract
Selected traits of the spatial organisation of a geographical environment which stem from two types of human behaviour (locational and interactive) are examined in this paper. An attempt is made to find and account for similarities in the spatial patterns of scalar and vector geographical data. In doing so, the paper analyses a core-periphery dichotomy, based on socio-economic information, and travel-to-work patterns. The paper uses the concept of a region as an integrating and focusing framework for the study. Formal regions (peripheral areas) are defined through the application of principal components analysis and cluster analysis; functional regions are defined by a standard rule-based regionalisation algorithm. The territory of the Czech Republic is used as an area for testing the basic hypotheses. The results show that there is some form of interrelationship and complementarity between the spatial distribution of scalar data and vector data, i.e. between spatial structure and spatial interaction patterns, which together form the spatial organisation of a geographical environment.

Work on the historical atlas of the sixteenth-century Poland
Authors: Rutkowski Henryk 
Published: April 2019

Abstract
The author begins with presentation of a programme of creating the detailed cartographic picture of the Polish-Lithuanian Commonwealth in the 16th century, proposed by Stanisław Smolka from the Jagiellonian University at the first congress of Polish historians in Cracow in 1880. This initiative was partially realised in the atlas of Ruthenian lands of the Polish-Lithuanian Commonwealth in the turn of the 16th and 17th century created by Aleksander Jabłonowski and printed in 1904 in Vienna. When Poland regained its independence, it became possible to organize further works. As their results two maps were designed, prepared and issued in the interwar period: the general map of the sixteenth-century Grand Duchy of Lithuania created by Jan Jakubowski, published in 1927 and 1928, and the map of Cracow Voivodship of the Four-Year Sejm period (1788–1792) elaborated by Karol Buczek with cooperation of several other persons and published in 1930 in Cracow.
The main topic of this article is a series of maps with commentaries prepared collectively in the Institute of History of Polish Academy of Sciences, entitled Atlas historyczny Polski. Mapy szczegółowe szesnastego wieku (Historical Atlas of Poland. Detailed maps of the 16th century) which includes Polish lands of the Crown. From the planned eight volumes with maps of individual voivodships or their groups, six were published successively in the years 1966–2018 and the last two are prepared for publishing in 2020. The author presents subject of the series and particularly contents of the main maps at the scale of 1:250,000.
This most detailed geographical and historical analysis of a large part of old Poland depicts the area in the 16th century, but it can also facilitate the process of gaining deeper knowledge about the history of these lands in the earlier and later centuries.
Applicability of Inlet Air Fogging to Marine Gas Turbine
Authors: Domachowski Zygfryd , Dzida Marek 
Published: April 2019

Abstract
The dependency of marine gas turbine on the ambient temperature leads to a decrease of the gas turbine power output in arid areas. Very often gas turbine power output demand is high and the power margins originally designed into the driver, has been exhausted. In such circumstances the inlet air fogging is an effective compensation of gas turbine power. In this paper an analysis of inlet air fogging applicability to marine gas turbine has been conducted. Different areas of ship’s voyage have been taken into account. The use of inlet air fogging in marine gas turbine must be evaluated on the basis of turbine characteristics, climate profile of ship’s voyage, and expectations of gas turbine power augmentation. The authors expect that the considerations provide useful guidance for users of marine gas turbines to decide the feasibility of installing an inlet air fogging system.

Published: April 2019

Abstract
To harness the endless hydrokinetic energy of the Kuroshio current, the joint research team of the National Taiwan University and the National Taiwan Ocean University has developed a floating Kuroshio turbine (FKT) system in Taiwan. In normal operation, the system floats at a certain small depth from the ocean surface to reduce the wave effects and take advantage of faster current speeds. In the present study, the effect of the mooring line on the system dynamics is investigated computationally. Two different auxiliary mooring line designs and, for each design, three different common mooring lines (polyester ropes of neutral buoyancy, iron chains, and 6×19 wires ropes with wire core) are examined. The study makes use of several commercial and in-house packages, integrated to find various coefficients. It is found that the mooring line, the auxiliary mooring line design, and the gravity centre can have a significant effect on system fluctuations in normal operation if the combination of these factors is not properly matched.

Published: April 2019

Abstract
This article concerns the issue of thermal degradation process of fuels, important from the perspective of the operation of turbine engines, especially in the context of new fuels/bio-fuels and their implementation. The studies of the kerosene-based jet fuel (Jet A-1) and its blends with synthetic components manufactured according to HEFA and ATJ technology, were presented. Both technologies are currently approved by ASTM D7566 to produce components to be added to turbine fuels. Test rig investigations were carried out according to specific methodology which reflects the phenomena taking place in fuel systems of turbine engines. The mechanism of thermal degradation process was assessed on the basis of test results for selected properties, IR spectroscopy and calculation of activation energy. The results show that with the increase of the applied temperature there is an increment of the content of solid contaminants, water and acid for all tested fuels. Thermal degradation process is different for conventional jet fuel when compared to blends, but also semi-synthetic fuels distinguished by different thermal stability depending on a given manufacturing technology.
The CFD Method-Based Research on Damaged Ship’s Flooding Process in Time-Domain
Authors: Li-Fen Hu , Huibo Qi , Yuemeng Li , Wubin Li , Shude Chen 
Published: April 2019

Abstract
The flooding process is one of the main concerns of damaged ship stability. This paper combines the volume of fluid (VOF) method incorporated in the Navier-Stokes (NS) solver with dynamic mesh techniques to simulate the flooding of a damaged ship. The VOF method is used to capture the fluid interface, while the dynamic mesh techniques are applied to update the mesh as a result of transient ship motions. The time-domain flooding processes of a damaged barge and a rectangular cabin model are carried out based on the abovementioned method, and the computational results appear compatible with the experimental data. During the flooding process, the motion of the flooding flow at different stages is observed and compared with that observed in real conditions. The time-domain research of the flooding process is the starting point for subsequent establishment of damaged ship’s roll movement and capsizing the mechanism of dead ship condition in wave.
Combustion and Emissions Investigation on Low-Speed Two-Stroke Marine Diesel Engine with Low Sulfur Diesel Fuel

Published: April 2019

Abstract
With the implementation and expansion of international sulfur emission control areas, effectively promoted the marine low sulfur diesel fuel (MLSDF) used in marine diesel engines. In this study, a large low-speed, two-stroke, cross-head, common rail, electronic fuel injection marine diesel engine (B&W 6S35ME-B9) was used for the study. According to diesel engine’s propulsion characteristics, experiments were launched respectively at 25%, 50%, 75%, 100% load working conditions with marine low sulfur diesel fuel to analyze the fuel consumption, combustion characteristics and emissions (NOx, CO2, CO, HC) characteristics. The results showed that: Marine diesel engine usually took fuel injection after top dead center to ensure their safety control NOx emission. From 25% to 75% load working condition, engine’s combustion timing gradually moved forward and the inflection points of pressure curve after top dead center also followed forward. While it is necessary to control pressure and reduce NOx emission by delaying fuel injection timing at 100% load. Engine’s in-cylinder pressure, temperature, and cumulative heat release were increased with load increasing. Engine’s CO2 and HC emissions were significantly reduced from 25% to 75% load, while they were increased slightly at 100% load. Moreover, the fuel consumption rate had a similar variation and the lowest was only 178 g/kW·h at 75% load of the test engine with MLSDF. HC or CO emissions at four tests’ working conditions were below 1.23 g/kW·h and the maximum difference was 0.2 or 0.4 g/kW·h respectively, which meant that combustion efficiency of the test engine with MLSDF is good. Although the proportion of NOx in exhaust gas increased with engine’s load increasing, but NOx emissions were always between 12.5 and 13.0 g/kW·h, which was less than 14.4 g/kW·h. Thus, the test engine had good emissions performance with MLSDF, which could meet current emission requirements of the International Maritime Organization.
The Analysis of Overall Ship Fuel Consumption in Acceleration Manoeuvre Using Hull-Propeller-Engine Interaction Principles and Governor Features

Published: April 2019

Abstract
The problem of reduction of greenhouse gas emissions in shipping is currently addressed by many research works and related industries. There are many existing and visionary technologies and ideas, which are conceptually defined or practically realised. This goal can be achieved in different ways, and reducing fuel consumption is one of the major methods. In these circumstances, the aim of this study is to analyse the possibility of fuel consumption reduction by using an alternative control strategy for low-speed marine diesel engines which would take into account the interactions between hull, propeller and main engine. For this purpose, a mathematical model including ship hull and propulsion system is developed. A case study is conducted for a ship for which the results of both the ship hull and screw propeller model tests are available. A low-speed two-stroke diesel engine is then selected for the considered ship. Two different governors are included in the model and their parameters are changed to investigate the dynamic behaviour of the system when simulating the forward acceleration mode in calm sea conditions. The research is mainly focused on variations of fuel consumption by the ship passing a certain distance to reach the nominal constant speed. It is concluded that, for a given travel distance, it is possible to save considerable amount of fuel at the expense of slight increase of journey time.

Published: April 2019

Abstract
The article focuses on a synthetic assessment of the validity of the application of certain methodologies in the management of development projects (including TPM, APF, APM)1. The authors, after discussing the basic assumptions of traditional methodologies and so-called “agile” ones, present the results of a development project implemented using the adaptive approach (Adaptative Project Framework). As the presented project was successful (full implementation of its assumptions ahead of time and with financial success), it was used as a basis on which the authors present the specificity of an adaptive approach in the management of development projects along with its critical analysis. The final result of the considerations is the presentation of the advantages and limitations of the application of such an approach to the management of development projects.
Data Selection as the Basis for Better Value Modelling
Authors: Zyga Jacek 
Published: April 2019

Abstract
The article is a voice in the debate on the scope of the application of statistical methods in real estate appraisal, written from the comparative perspective. It presents the results of an illustrative valuation of housing units with the use of databases of various sizes, constructed on the basis of publicly available data from the register of property prices and values. Against this background, the article presents an analysis of differences between the objectives and published results of valuations, which exemplify broadly understood property price modelling or property value modelling, as well as of activities focused around appraising a specific object. The conducted experiments demonstrated that, for the purposes of real estate appraisal itself, the selection of data is more useful than searching for a price model.
Property Valuation and Taxation for Fiscal Sustainability – Lessons for Poland
Authors: Grover Richard , Walacik Marek 
Published: April 2019

Abstract
Research undertaken by the World Bank in Europe and the Central Asia Region indicates that there are four principal preconditions for introducing value-based recurrent property tax reforms: comprehensive property registration, a reliable source of data about the prices achieved in transactions, a valuation infrastructure that complies with internationally-recognized standards, and an efficient tax collection system. In spite of the arguments in favor of value-based recurrent property taxes, many countries raise revenue from recurrent property taxes using an area basis, and most countries raise relatively little revenue from recurrent property taxes. The paper has been written according to both the dogmatic-legal method and comparative method. It presents current solutions adopted in post-Soviet European countries in order to draw out recommendations and suggestions for Poland. The original reasoning for the paper is that, amongst many scientific papers concerning thorough debate of property tax systems, few have focused on post-Soviet countries and the issues that arise in transition countries. Most concern Western European or North American countries with different economies, politics, institutions, and histories to the Eastern ones. Authors of the paper believe that the article can fill the gap in discussions on the shape of the property tax system reform in Poland and the reforms carried out in Eastern Europe countries.
Linear and Nonlinear Weighing of Property Features
Authors: Barańska Anna 
Published: April 2019

Abstract
Determining the weights of market features of real estate in explaining their prices is one of the basic objectives of market analysis, performed as part of the property value estimation process. In practice, property appraisers usually settle for basic methods of determining weights, for example based on the principle of ceteris paribus or on the basis of linear correlation coefficients. The article proposes the use of curvilinear correlation coefficients for this purpose; an attempt of such use was made and the obtained results were compared with the weights determined on the basis of linear correlations. The conducted analyses proved that the inclusion of curvilinear correlations at the stage of market analysis, allows for extracting a greater number of features recognized as price-creating, i.e. leads to a smaller loss of market information and is a more reliable tool for determining the weights of attributes in price explanation.
