The Influence Of Financing On The Dynamics Of Housing Prices
Authors: Bełej Mirosław , Kulesza Sławomir 
Published: June 2015

Abstract
Real estate market can be thought of as an open, dynamic system. It means that it is able to exchange stimuli with other open systems, and that its state evolves in a way that might be described mathematically. It turns out that two main processes contribute to the overall evolution of the real estate market: long-term, predictable evolution, interrupted by sharp changes of catastrophic origin. In this picture, national housing funds play an important role in supporting the housing finance: on one hand they could either stimulate or suppress the real estate market influencing the availability of the mortgage credit, but on the other hand, they could also help to stabilize prices. In this study, an attempt was made to determine the degree of relationship between the volume of mortgage financing from national housing funds and the dynamics of real estate prices.
Estimating The Size Of The Secondary Real Estate Market Based On Internet Data Sources
Authors: Beręsewicz Maciej 
Published: June 2015

Abstract
As a result of the growing digitization of society and the development of electronic economy, current statistical data sources, including administrative registers, do not satisfy the information needs of society. Therefore, there are growing gaps in the statistical coverage of a number of sectors of the economy. One example of such a gap is the secondary real estate market, which is only partially accounted for by official statistical data sources. On the other hand new data sources such as the Internet or Big Data tend to decrease information gap in official statistics. The Web portals that specialise in brokerage on real estate market should be not neglected as a data source for statistics. Therefore, the aim of the paper is to use two Web portals devoted to the housing market to estimate supply measured in the number of flats offered to sale in Poznań, Poland. In addition, classification and quality of Web portals will be discussed.
Polish Absolute Return Funds And Stock Funds. Short And Long Term Performance Comparison
Authors: Perez Katarzyna 
Published: June 2015

Abstract
In this paper I focus on analyzing whether Polish absolute return funds, which I call quasi-hedge funds, add value to a portfolio of an individual investor by reaching higher returns than Polish stock funds. I use a sample of 25 Polish absolute return investment funds to contrast their short and long term performance, measured by Sharpe, Sortino and Jensen ratios, to the short and long term performance of 20 biggest Polish stock funds and build rankings based on that performance. Later I build funds of funds (with a different number of stock funds and/or quasi-hedge funds) and check which of them is the most efficient. I find out that in both short and long term Polish quasi-hedge funds have better returns than stock funds and they add much value to the investors’ portfolios. It can be explained by the fact that they are much smaller and younger than traditional funds, so they have much higher potential to grow and reach abnormal returns.

Abstract
Diuron is a phenylurea-based residual herbicide with toxic and endocrine disrupting effects. The aims of the present work were the comparison of the efficiency of various advanced oxidation processes, such as direct ultraviolet photolysis, ozonation, their combination, and heterogeneous photocatalysis from the point of view of the transformation rate of diuron, rate of mineralisation and dehalogenation, formation of aromatic intermediates, and ecotoxicological effects of the formed multicomponent solutions during the treatments. The initial rates of transformation of diuron are in the order of ozonation < heterogeneous photocatalysis < UV photolysis < combination of UV photolysis and ozonation. Each method provided similar tendencies in the decrease of the concentration of organically bound chlorines (AOX) since, until the diuron was completely degraded, the concentration of AOX decreased almost to zero in each case. However, only heterogeneous photocatalysis was found to be effective in terms of mineralisation. Ecotoxicological results showed that in each case, except for ozonation, the toxicity of the treated solutions changed through a maximum during the transformation of diuron. The maximum value was found to be lower in the case of heterogeneous photocatalysis. Thus, the formation and decomposition of by-products of relatively higher toxicity than diuron can be supposed. Our results confirmed that the amount of the formed (aromatic) intermediates, their quality and specific toxicity strongly depend on the applied processes.
Study of the Interference effects of Aluminium on the Atom- And Ion-Lines of Alkaline Earth Metals in Aqueous Solutions Using an ICP Spectrometer with Axially Viewed Plasma
Authors: Bánhidi Olivér 
Published: June 2015

Abstract
The main advantage of inductively coupled plasma spectrometers with axially viewed plasma relative to the radially viewed plasma is the better detection power. The detection limits of the former are about 5-10 times lower than the latter. On the other hand, the axially viewed plasma has disadvantages. The most notable is the increased number of interference effects. In this paper, the study of the interference effects of aluminium on the atom- and ion-lines of alkaline earth metals are presented by examining different types of sample-introduction devices, such as a simple Meinhart-type concentric nebuliser, a V-groove nebuliser using a Sturman-Masters spray chamber, and an ultrasonic nebuliser
Introduction
Authors: Valdez Juan R. 
Published: June 2015

AbstractGiven the persistent legacy of colonization and slavery in the Caribbean, a significant portion of recent scholarship on the island internationally known as Hispaniola is dedicated to debunking (neo)colonial myths (Buck-Morss 2009; San Miguel 2005). Not the least of these myths is the idea that this island’s peculiar history produced a “lower”, not fully civilized race of speakers. In keeping with the task of myth-busting, this special issue of the
Causative get-constructions in the dialogued passages in F. Scott Fitzgerald’s novels The Beautiful and Damned and Tender Is the Night as gender-conditioned structures
Authors: Gołąbek Rafał 
Published: June 2015

Abstract
It goes without saying that in modern sociolinguistics there is a consensus with regard to the fact that the language of males and females differs. The initial sections of the article briefly address the peculiarities of gendered speech as to provide a theoretical background for checking whether the causative get is used similarly or differently by men and women in the two of F. Scott Fitzgerald’s novels: The Beautiful and Damned and Tender Is the Night. The basic expectation formed is that the motifs for triggering the use of causative get are of social rather than structural nature. Before the analysis is carried out, the group of the English periphrastic causatives are sketchily characterized. Generally, what has been found is that there is a clear, socially-motivated pattern of how F. Scott Fitzgerald uses the causative get in the dialogued occurrences in his two novels. Get is a characteristic of men’s talk, but it is also the expected form while female characters address male ones - hence the verb is labelled as “masculine” get. Moreover, it has been discovered that there does not seem to be any particular pattern in either the speaker’s mood or the speaker’s attitude expressed that would trigger the use of the causative verb in question. Yet, what seems to be a well-defined tendency, when it comes to the speaker-hearer power relation, is that the speaker usually assumes a more superior position than the hearer when he or she uses the causative verb. The superiority in most cases is strongly associated with masculinity. Hence, what is postulated is that the causative get is labelled not only as “masculine" but also as “superior”.

Published: June 2015

Abstract
This study deals with the distance estimation issue in low-power wireless systems being usually used for sensor networking and interconnecting the Internet of Things. There is an effort to locate or track these sensor entities for different needs the radio signal time of flight principle from the theoretical and practical side of application research is evaluated. Since these sensor devices are mainly targeted for low power consumption appliances, there is always need for optimization of any aspects needed for regular sensor operation. For the distance estimation we benefit from IEEE 802.15.4a technology, which offers the precise ranging capabilities. There is no need for additional hardware to be used for the ranging task and all fundamental measurements are acquired within the 15.4a standard compliant hardware in the real environment. The proposed work examines the problems and the solutions for implementation of distance estimation algorithms for WSN devices. The main contribution of the article is seen in this real testbed evaluation of the ranging technology.
Worldview Struggles under a New Climate Regime
Authors: Johannessen Jill 
Published: June 2015

Abstract
The UN summit on climate change in Durban constituted an important moment in the continuous discourse on how to understand climate change and the framing of the problems and solutions. A new emergent frame of understanding could be detected in the press, which the author calls the ‘out-dated worldview’ frame. This frame contains a critique of the clear-cut division between developing vs. developed countries from the 1992 Rio Convention, and may influence how we understand burden-sharing roles in a new global climate deal. In an eager attempt to include all major polluters within a new climate regime, there is a danger that the principle of ‘common but differentiated responsibility’ will be ignored, which may be an attempt to excuse the rich industrialized countries from their responsibility after 150 years of benefitting from fossil-fuel-driven development.
The Complexity of Public Relations Work
Authors: Johansson Bengt , Larsson Larsåke 
Published: June 2015

Abstract
Research on the PR-function is extensive, especially in the US and the UK. The managertechnician dichotomy is well known, but has been challenged by recent research where more nuanced perspectives on PR-managerial roles are displayed. In relation to this complexity of PR-managerial roles the article investigates the function and role Swedish public relations managers perform and play in their organizations. The Swedish case, with its high proportion of PR practitioners employed by public authorities, was used to further explore the complexity of PR work. The empirical data was a survey distributed to a random sample of members of the Swedish Public Relations Association, with a managerial or head/ director position, representing all industry/societal sectors. 261 persons completed the survey, giving a response rate of 30 percent. The study confirmed previous research of a more complex picture of the PR-managerial level. One important conclusion was therefore that the simple dichotomy between managers and technicians cannot be used to understand managerial level positions in the public relations context. This complexity was even further emphasized when comparing PR-mangers in the private and the public sector. One challenge pointed out for future research was to develop analyses of PR managerial roles in different types of organizations.
Extraction and optimization of Mucuna pruriens for dyeing of leather
Authors: Sundari Natarajan 
Published: June 2015

Abstract
The present study reports on the leaching of natural pigment from Mucuna pruriens for dyeing of chrome tanned leather samples. The experiments were performed at temperature (30-70°C), time (30-90 min), feed to solvent ratio (1:3-1:7) and particle size (0.25-0.75 mm) using ethanol as solvent. The influence of process variables on percentage yield has been studied and the conditions were optimized using Box-Behnken design. The optimized conditions for intensified extraction was found to occur at a temperature of 60°C, extraction time of 1 hr, for a feed to solvent ratio of 1:5 and 0.75 mm particle size. The % yield under optimized conditions was found to be 47%. The extraction results were found to agree well with the statistical model (R2 = 0.9740). The colouring ability of extracted dye has been tested on wet blue goat leathers. The dyed leather exhibited a better colour value, strength and fastness properties as inferred from reflectance and visual assessment tests.

It is proven that the residual after alkali solvent was cellulose, the filtrate by the acid precipitation of the liquor was lignin, the solid by the ethanol extraction of the liquor was hemicellulose. The optimum dissolution conditions were determined by single-factor experiment as follows: the concentration of H2O2 5.0%, pH 11.5, dissolution temperature 60°C, dissolution time 3.0 h, the ratio of liquid to solid 30 mL/g. And chemical analysis were employed to determine the purity of the components separated. The structure of the components separated were identifi ed by FT-IR, SEM, XRD and NMR. The cellulose recovery yield can achieve to 84.2% and lignin recovery yield is 86.6%, the hemicellulose recovery yield is 96.7%. After recycling the solvent 3 times, the recovery yield of cellulose, lignin and hemicellulose were 82.7, 87.6 and 97.4%, and the purity of cellulose, lignin and hemicellulose were 98.0, 96.5 and 98.7%, respectively.

Published: June 2015

Abstract
Towards the end of the nineteenth century and the beginning of the twentieth century new technological evolutions and material developments gave rise to different modular structural flooring systems, which allowed light but strong floors to be constructed. This paper gives an overview of the evolution in flooring systems, their durability problems, and how to solve them. Similar systems also have been used for roof constructions. The strengthening of an atypical vaulted roof structure in the “Het Depot” theatre in Leuven, composed of terracotta arch and panel elements, showing its specific problematic and its specific revalorization approach serves as a case study to illustrate the methodologies applied.

AbstractPatient-specific simulations of human physiological processes remain the challenge for many years. Detailed 3D reconstruction of body anatomical parts on the basis of medical images is an important stage of individualized simulations in physiology. In this paper we present and develop the methods and algorithms for construction of patient-specific discrete geometric models. These models are represented by anatomically correct computational meshes. Practical use of these methods is demonstrated for two important medical applications: numerical evaluation of fractional flow reserve in coronary arteries and electrocardiography simulation

Effects of Neutron Irradiation on Bromobenzene and some of its Derivatives
Authors: Poncha R. P. , Rag C. L. , Sharma H. D. 
Published: June 2015

Summary
The retention value R, defined as the percentage of activity retained in the organic combination after irradiation of an organic halide has been determined for bromobenzene, o, m and p bromonitro benzene, o, m and p bromoaniline and its sulphate. The values of R for bromobenzene show wide Variation depending on the irradiation Container etc. apart from pretreatment for purification. The isomers of derivatives of bromobenzene show that there are no marked differences in the values of R but minor differences have been observed which may be due to orienting effect of the substituents in the benzene nucleus. The effect of dilution on R
of bromobenzene using benzene and hexane as solvents has been studied and it is shown that the retention value goes down in benzene but in hexane it remains constant. The scavenging effects by addition of bromine and allyl bromide on bromobenzene have shown that R
goes down to ~ 30 percent in the former and ~ 87 percent in the latter case.
Oxygen-Effect in Annealing of Recoil Damage in Cobalt Chelates-Tris-Acetyl-Acetone Co(III) and Bis-Salicylaldehyde Triethylenetetramine Co(III) Chloride
Authors: Nath Amar , Rao K. Annaji , Thomas V. G. 
Published: June 2015

Summary
A marked 'oxygen effect' is observed for several cobalt complexes in thermal annealing. Kinetic data are reported for recoil damage, after 59Co (γ, n)
58Co and 59Co (n,
γ)
60Co- reactions in trisacetylacetone Co (III) and bis-salicylaldehyde triethylenetetramine Co (III) chloride respectively. When the thermal treatment is carried out in N2 or vacuum (viz., in absence of oxygen), the magnitude of Saturation anneal is considerably higher. Aliquots annealed to Saturation in presence of air can be made to undergo further annealing, if the thermal treatment is continued at the same temperature but in the absence of air (in vacuum or nitrogen).
It is suggested that during an isothermal annealing run electrons are released from variable depth traps, and interact with the metastable species (damage centres) formed by virtue of interaction of recoil cobalt atom with a chelate molecule. The adsorbed oxygen on the surface acts as deep electron trap and suppresses annealing. Once it is displaced by N2 (or vacuum), annealing proceeds further. The adsorbed oxygen is not found to affect the percentage contribution from individual rate processes (corresponding to different trapping centres) to an equal extent. This shows that the spatial distribution of different trapping centres in the bulk is not homogeneous.
Recoil Tritium Reactions in Simple Aliphatic Compounds
Authors: Cipollini R. , Stöcklin G. 
Published: June 2015

Summary
Some reactions of recoil tritium produced via the 3He (n, p) T- and the 6Li (n, α) T-process, respectively, have been studied in gaseous and liquid aliphatic compounds of the type RX (X = NH2, OH, SH, halogen).
Except for a remarkably high HT-yield in gaseous and liquid labile Η-containing systems the product forming mechanisms seem to follow the general pattern of the chemistry of energetic tritium atoms.
Liquid phase competition experiments in equimolar CH3NH2/C2H5NH2(I2)- and CH3NH2/n-C3H7NH2(I2)-systems show a stronger structure effect on hydrogen replacement than expected on the basis of the "impact model". The ratios of the relative yields per C-Η bond are 1.00 : 0.67 : 0.50 for methyl-, ethyl- and n-propylamine, respectively.
The effect of bond energies on excitation-decomposition following hot hydrogen substitution has been studied using scavenged gaseous, equimolar CH3X/C2He-systems. The CH2TX-yields are shown to decrease in the order
CH2TF > CH2TOH > CH2TCl > CH2TNH2 > CH2TSH
thus indicating that the energy of the weakest bond in the molecule plays a major yield-determining role. Pressure- and phase-effects confirm that a considerable fraction of the hot substitution product can decompose at 1 atmosphere before collisional de-excitation occurs. Primary steric and chemical factors seem to be small compared to the secondary decomposition effects, particulary for compounds with weaker bonds.
