THEORETICAL STUDY OF THE EFFECT OF PROBE SHAPE ON ADHESION FORCE BETWEEN PROBE AND SUBSTRATE IN ATOMIC FORCE MICROSCOPE EXPERIMENT
Authors: Yang Li , Hu Junhui , Kong Lingjiang 
Published: January 2014

Abstract
The quantitative description of adhesion force dependence on the probe shape is of importance in many scientific and industrial fields. We performed a theoretical study on the influences of the probe shape (the sphere and parabolic probe) on the adhesion force at different humidity in order to elucidate how the adhesion force varied with the probe shape in atomic force microscope manipulation experiment. We found that the combined action of the triple point and the Kelvin radius is the guiding trend of the adhesion force, and these two fundamental parameters are closely related to the probe shape. Meanwhile, the theoretical results demonstrated that the adhesion force are in a good agreement with the experiment data if the van der Waals force is take into account.

MAGNETOSTRUCTURAL J-CORRELATIONS IN Fe(III) COMPLEXES – A REVISION
Authors: Vranovičová Beata , Boča Roman 
Published: January 2014

Abstract
The magnetostructural correlations in Fe(III) complexes, originally outlined by Gorun and Lippard has been revised. Other correlation variants have been tested and the dataset enlarged for more recent entries possessing the Fe-O-Fe bridge including dinuclear, tetranuclear and hexanuclear Fe(III) complexes. The resulting relationships confirm that instead of the original suggestions, the correlation could stay as a linear relationship which covers the possibilities of positive values of exchange coupling constants.
SYNTHESIS, CRYSTAL STRUCTURE AND SPECTRAL PROPERTIES OF COPPER(II) AND COBALT(II) 3-METHYLTHIOPHENE-2- CARBOXYLATO COMPLEXES WITH FUROPYRIDINES
Authors: Miklovič Jozef , Bašnárová Miroslava , Segľa Peter , Koman Marián 
Published: January 2014

Abstract
The synthesis and characterization of eleven new Cu(II) and Co(II) complexes is reported. The complexes were characterized by elemental analyses, infrared and electronic spectra. Copper(II) with 3- methylthiophene-2-carboxylic acid (HMTK) forms a dinuclear complex of the acetate type [Cu2(MTK)4(H2O)2]. By reaction of this complex with 2-metylfuro[3,2-c]pyridine (MeFP), not only acetate type complexes [Cu2(MTK)4L2] (L= FP, MeFP) were obtained, but also monomeric complex [Cu(MTK)2(FP)2]. In the cases of [1]benzofuro[3,2-c]pyridine (BFP) and 2-(3-trifluoromethylphenyl) furo[3,2-c]pyridine (CF3FP) only monomeric complexes [Cu(MTK)2L2] (L = BFP, CF3FP) were obtained. It is possible to observe, that with increasing amount of the ligand, the yield of monomeric complexes increases too. In monomeric complexes, the carboxylic group of anionic MTK binds to atom Cu(II) by asymmetrically chelating O,O-coordination. The crystal structure of the complex [Cu(MTK)2(MeFP)2] was determined by X-ray single crystal structure analysis. The copper(II) atom lies in the crystallographic centre of symmetry in an distorted tetragonal-bipyramidal arrangement. The structure of this complex confirms an asymmetric chelate coordination of the carboxylic group. HMTK and Cobalt(II) form coordination compound [Co(H2O)6](MTK)2 with assumed ionic mode of coordination of anionic MTK. With furopyridines monomeric complexes [Co(MTK)2L2] (L= FP, MeFP, BFP, CF3FP) with distorted octahedral coordination polyhedron around Co(II), were formed.
HIGH – PERFORMANCE LIQUID CHROMATOGRAPHIC METHOD FOR ENANTIOSEPARATION OF UNDERIVATIZED α-AMINO ACIDS USING CYCLOFRUCTAN – BASED CHIRAL STATIONARY PHASES
Authors: Moravčík Jakub , Hroboňová Katarína 
Published: January 2014

Abstract
Chromatographic columns with chiral stationary phases based on chemically - bonded derivatized cyclofructans were evaluated for HPLC enantioresolution of underivatized α-amino acids. The analytical study of chiral separation of these analytes was focused on the selection of suitable chiral stationary phase and mobile phase. Using isopropyl carbamate cyclofructan 6 as a chiral stationary phase, α- amino acid optical isomers were separated. The retention and enantioseparation of chiral amino acids were also influenced by a mobile phase composition. The mixture methanol/acetonitrile/acetic acid/triethylamine (75/25/0.3/0.2 v/v/v/v) was found to be the most effective mobile phase for HPLC separation of studied compounds. HPLC enantioresolution of chiral amino acids was thermodynamically studied. Based on the enthalpy and entropy contribution values calculated from the van´t Hoff equation, HPLC enantioseparation under chosen chromatographic conditions was found to be an enthalpically driven.
FLAVONOLS HPLC ANALYSIS, IN VITRO BIOLOGICAL ACTIVITIES IN SELECTED HUMULUS LUPULUS L. GENOTYPES
Authors: Maliarova Maria , Maliar Tibor , Girmanova Jana , Lehotay Jozef , Kraic Jan 
Published: January 2014

Abstract
The Humulus lupulus L. is well known as necessary raw material for beer production. The main structural classes of chemical compounds identified from hop cones include terpenes, bitter acids, prenylated chalcones, and flavonol glycosides. They were subjects of presented work. The content of quercetin was found in the range 490 - 1092 μg/g and that of kaempferol from 218 to 568 μg/g of the dry hop cones. The content of isorhamnetin was very low in all varieties. From biological activities in vitro point of view, relative high level of inhibition activity was observed for six hop genotypes - Zlatan, Lučan, and the Oswald's clones 31, 70, 71, 72, 114 on both enzymes thrombin and urokinase, but without correlation to analyzed flavonols content. In spite of this, antioxidant activity, measured by both the BCLM and HPE methods, was found high and seem to be in correlation with content of analyzed flavonols. Particularly the Oswald's clone 114 expressed very potent biological activities. In general, obtained results indicate that hop cones are valuable material also for other application others than beer production.
Reflections on the Distinctiveness of Public Administration as a Discipline
Authors: Ringeling Arthur 
Published: January 2014

Abstract
Th e paper discusses some issues which are relevant for the further development of Public Administration as an academic discipline. Firstly, there is reason to be skeptical about universal features of this discipline, as there is much variety in the practice of Public Administration around the world. Secondly, the orientation of Public Administration towards public values is emphasized. Th irdly, the relevance of the concept of a democratic Rechtsstaat as a starting point for the design of Public Administration content must be stressed. And finally, the paper discusses institutional issues, e.g. the question if education of future civil servants should take place at government-controlled schools or within universities.
Distinguishing facts from beliefs: fuzzy categories
Authors: Rabinowitz Mitchell , Acevedo Maria , Casen Sara , Rosengarten Myriah , Kowalczyk Martha , Portnoy Lindsay Blau 
Published: January 2014

Abstract
This paper presents results from five studies that investigate how people perceive the distinction between facts and beliefs. The central question being asked is whether the features that distinguish the categories of facts and beliefs are distinct or overlapping. In each of the five studies, participants are presented with content statements and asked the degree to which they agree with a given statement, the degree to which they think others would agree with it, and whether the statement was a fact or a belief. From these ratings, six possible patterns were derived. The results showed that in many content areas the patterns that describe the statements they categorized as facts and those that they categorized as beliefs had considerable overlap. In addition, participant consensus as to which statements were to be considered facts versus beliefs varied from high to low depending on the specific content being evaluated.
Pilot assessment of nonverbal pragmatic ability in people with asperger syndrome
Authors: Rodríguez Muñoz Francisco J. 
Published: January 2014

Abstract
The purpose of this study is to present a diagnostic tool to assess the nonverbal pragmatic behaviors of people with Asperger syndrome, with the intent to give an account of the severity of symptoms in the area of nonverbal interaction, as well as providing a profile of nonverbal behaviors that may be targeted for intervention. Through this communication profile, overall nonverbal ability is calculated in a group of 20 subjects with Asperger syndrome. The proposed scale also includes the measurement of the following nonverbal dimensions: (1) eye gaze, (2) facial expression, (3) body language and posture, (4) proxemics, (5) gestures, and (6) paralanguage. The results of this assessment suggest low nonverbal pragmatic ability in these subjects, show specific deficits in nonverbal communication, and capture variability in nonverbal behavior in individuals with AS.
VALUATION FOR LOAN SECURITY PURPOSES IN THE CONTEXT OF A PROPERTY MARKET CRISIS - THE CASE OF THE UNITED KINGDOM AND POLAND
Authors: Źróbek Sabina , Adamiczka Jerzy , Grover Richard 
Published: January 2014

Abstract
Valuation for loan security purposes has been a key issue related to property valuation, financial markets and the economy in general. This paper attempts to demonstrate the main reasons for interest in this field by referring to the situation in Poland and the United Kingdom. Moreover, the conditions of valuation for loan security purposes in Europe have been outlined, as well as the new challenges that property valuers have to face. Questions regarding unified and harmonious valuation standards have been presented in relation to international, European and domestic professional standards and legal regulations. The conclusion addresses further challenges of property valuation that must be tackled urgently, because valuation results are strictly connected with the profitability and safety of investments in the property market. Furthermore, the paper emphasizes that uncertainty in the valuation process also needs to be taken into account, as the appraised properties secure loans given by institutions funding their development.
REAL ESTATE MARKET SYSTEM - PHASE SPACE THEORY APPROACH
Authors: Radzewicz Anna 
Published: January 2014

Abstract
The real estate market poses a topic of research in the theoretical sense, as well as encouraging researchers to search for new methods/tools/platforms which would help to understand, manage and undertake all kinds of activities (decisions) within its realm. The process of globalization, need to constantly gather information (create extensive registers), data management, implementation of complicated computing procedures (which only seemingly provide solutions), and awareness and knowledge of market participants are supposed to lead us to "ultimately understand" the structures of the real estate market. However, in most cases, the decisions made in the real estate market realm are not rational.
Market participants do not always act accordingly to the (economic) presumptions of the market and many of their behaviors can easily be viewed as chaotic and impulsive. Owing to this fact, it seems justified to invoke mathematical and physical concepts, and apply them to the real estate market.
This article describes the concept of how the real estate market is perceived according to the phase space theory. Phase space is understood as a multidimensional space of market events where the transfer of rights to real estate takes place and decision-making processes occur. Transaction prices, on the other hand, indicate market development and are an emanation of decision-making processes.
The goal of this article is to provide proof for the hypothesis that the real estate market is a system existing in multidimensional phase space and that the complexity of this space affects the unit price of real estate.
AN ATTEMPT TO IDENTIFY THE SEASONALITY OF HOUSING PRICES IN SELECTED POLISH CITIES IN 1996-2012
Authors: Trojanek Radosław 
Published: January 2014

Abstract
Markets of any goods, like the whole economy, are subject to fluctuations, which are usually determined by the economic situation. Fluctuations of different strength affect all markets, including that of real estate. Studies conducted in other countries show that the number of transactions and the price of apartments on the housing market tend to increase in the spring and summer rather than in autumn and winter. In this paper, an attempt was made to verify this relation in Polish conditions using examples of several cities in the period of 1996-2012.
THE USAGE OF POSITAL CANOPEN AGS15 INCLINOMETERS FOR DIAGNOSTIC MONITORING OF SLENDER STRUCTURES
Authors: Wyczałek Ireneusz , Plichta Artur , Wyczałek Michał 
Published: January 2014

Abstract
This paper concerns the possibility of using AGS15 capacitive inclinometers in the geodetic monitoring of slender structures. The basics of geometric monitoring have been introduced, and the features of inclinometers that can be used in these studies have been described. Main expectations towards them have been formulated. Three tests were conducted: (1) a few days' stability test of readings, (2) the test of inclinations controlled tachimetrically and (3) continuous survey of a physical object. It has been found that in order to obtain satisfactory results it is necessary to correct the readings due to the drift and the effect of temperature. The works conducted as part of described project work are not capable of identifying those indicators. To achieve them there were designed the system that support the acquisition and processing of the measurement and also the collection and transmission of results. In the conclusions authors stated that inclinometers AGS15 can be suitable for monitoring, but the works aimed at improving their performance should be undertaken.
Analysis of changes in cyanobacterial and algal flora of selected water reservoirs in Wrocław between 1878 and 2010 (south-west Poland)
Authors: Richter Dorota 
Published: January 2014

Abstract
The paper includes the results of research carried out between 2006-2010 in the city of Wrocław (Poland). The water reservoirs selected for the analysis had previously described phycoflora and these studies were excellent comparative material for the today’s condition of their algoflora. The aim of this research was to conduct detailed studies of the current taxonomic composition of phycoflora in the chosen water reservoirs and to trace the changes which have taken place over time. The research determined the degree of similarity between the different communities in terms of the occurrence of common species and also the changes in their quantity. The study revealed 535 species of cyanobacteria and algae belonging to five phylas. The comparison of the composition of phycoflora from the studied ecosystems from previous years with the current results provided a model study showing the direction and pace of changes in the composition of the flora of cyanobacteria and algae in a given time. The species composition of cyanobacteria and algae in each year is adequate to the trophy of the studied water bodies. The processes in transforming communities of cyanobacteria and algae have led to the stabilization of the current status of the reservoirs as eutrophic.

Among them, two are new records for Europe (stomatocysts 330 and 208) and another two are new for Poland (stomatocysts 112 and 387). Descriptions are provided together with SEM illustrations. General data about cyanobacteria and eukaryotic algae occurring with these stomatocysts are enumerated.
The effect of long-term contamination by heavy metals on community and genome alterations of Chironomidae (Diptera) in a stream with mine drainage water (southern Poland)
Authors: Szarek-Gwiazda Ewa , Michailova Pareskeva , Ilkova Julia , Kownacki Andrzej , Ciszewski Dariusz , Aleksander-Kwaterczak Urszula 
Published: January 2014

Abstract
This paper reports on studies of the effect of heavy metals on the Chironomidae that inhabit the Matylda stream, which has been contaminated for about 100 years by discharge water from a zinc and lead ore mine. Stream sediment was strongly polluted by Cd, Pb, Cu and Zn. These metals did not affect the Chironomidae community but strongly changed the genome system of the Chironomidae species that inhabited the sediment. The salivary gland chromosomes of six species belonging to the two genera Chironomus and Prodiamesa are analyzed. In all species the somatic index is calculated on the basis of somatic chromosome alterations. Chironomus riparius has the highest numbers of somatic alterations and the highest somatic index — 9.67. The smallest chromosome G carries the key structures known as “Balbiani rings”, which play an important role in species development. This chromosome is very sensitive in the genome of the most studied species. The high sensitivity of the C. riparius genome is discussed in light of its DNA organization. The results show a high response of the salivary gland chromosomes to heavy metal pollution, and this makes them a valuable indicator in the assessment of water quality and detection of mutagenic agents in the aquatic environment.

Abstract
This paper presents an analysis of learning effectiveness for the courses “Selected issues in visual rehabilitation” and “Ophthalmology and ophthalmic nursing” taught in the years 2009-2011 at the Medical University of Bialystok, Poland. We compared the effectiveness of traditional and distance learning methods; an e-learning platform was implemented experimentally for the purpose of this study. We assessed the usefulness of online learning in terms of organization, knowledge gained and students’ satisfaction with the course. The study was conducted among 75 second year master degree students in the nursing field in the academic years 2009/2010 and 2010/2011. The students were divided into two groups. For the study group of 39 persons (52%), lectures and seminars took place on an e-learning platform, while 36 persons (48%) in the control group attended traditional classes. 80% of students in the e-learning group and 89% of students in the traditional group assessed the organization of both forms of courses positively. The fact that the majority of students in both the e-learning (89%) and traditional classes (86%) gave positive feedback indicates that for both forms there was a high level of content and technical preparedness. The mean scores of the final exam for both courses were 82% in the e-learning group and 79% in the traditional group in the years 2009- 2011. The above results show that both forms of learning are equally effective.

The Stability of Gene Selection in Microarray Experiments
Authors: Wietlicka-Piszcz Magdalena 
Published: January 2014

AbstractThis paper addresses the issue of the stability of lists of genes identified as differentially expressed in microarray experiments. The similarities be- tween gene rankings yielded by various gene selection methods performed with resampled datasets were assessed. The mean percentage of overlapping genes for two rankings varied from 10 to 90% depending on the applied gene selection method and the size of the list. The assessment of the stability of obtained gene rankings seems to be relevant in the analysis of microarray data.
