Impacts of natural hazards on an early industrial community: A case study of North Bohemia and its implications for long-term vulnerability assessment
Authors: Raška Pavel , Dubišar Jakub 
Published: April 2017

AbstractRegional databases of natural hazards and their social impacts have been increasingly established from documentary data to provide a rationale for the adoption of new disaster risk reduction strategies. This approach is extended in this article by pointing out factors that may underlie the changes in social vulnerability to natural hazards and that may cause non-homogeneities in long-term vulnerability assessments. We use the newly-established historical multi-hazard database for North Bohemia, based on a thorough search in a local newspaper. Altogether 275 records reporting 599 individual hazard events were analysed with respect to their relative direct social impact. Finally, we discuss the uncertainties resulting from the use of documentary data, and illustrate how long-term changes in social vulnerability are influenced by timedependent societal understanding of what is considered a hazard. This, in turn, accentuates the dynamics of cultural factors that should be considered when designing new risk reduction strategies.
Environmental factors influencing the distribution of agricultural terraces: Case study of Horný Tisovník, Slovakia
Authors: Slámová Martina , Krčmářová Jana , Hronček Pavel , Kaštierová Mariana 
Published: April 2017

AbstractThe cadastral district of Horný Tisovník represents a traditionally managed Carpathian mountain agricultural landscape with extensive terraces. It was historically governed by two counties with different feudal economic systems - agricultural and industrial. This paper aims to enrich traditional methods in environmental history. We applied geospatial statistics and multivariate data analysis for the assessment of environmental factors influencing the distribution of agricultural terraces. Using linear models, the hypothesis was tested that the terrace distribution is functionally related to selected factors (affiliation to the historic counties; average altitude and slope; distance from water, buildings and settlements; units of natural potential vegetation; and current land use). Significantly greater amounts of terraces were located in the agricultural county compared to the industrial county. A principal component analysis showed the coincidence between the current agricultural land use and higher concentrations of terraces occurring in lower altitudes, closer to settlements and buildings, and within the unit of Carpathian oak-hornbeam forests. These findings regarding the most significant factors influencing the distribution of terraces are used in proposals for incentives to improve the management of the traditional agricultural landscape.

Abstract
The results of an analysis of land use development in the Morava River floodplain (Czech Republic) using GIS from 1836 to the present, are the subject of this article. The results are based on the analysis of historical maps, using the landscape matrix assessment of the Morava River floodplain. The final analyses were processed from land use maps of the floodplain at a scale of 1 : 25,000 in five time horizons. These maps were compared with the present state of landscape by GIS methods. The study area was assessed according to five geomorphological areas from the northern/higher part to the southern/lower part of floodplain. In 1836 the landscape matrix of the floodplain was composed of meadows and forests. Forest components decreased minimally but the changes are more important. The grassland area (meadows and pastures) decreased but arable land, as well as settlements, increased very significantly. In the 1950s the landscape matrix was composed of a mosaic of alluvial forests, meadows and arable land. Currently, the predominant landscape matrix consists of arable land and isolated forest complexes.
Review Essay. Energy landscape research – Lessons from Southern Europe?
Authors: Greer-Wootten Bryn 
Published: April 2017

AbstractThe Moravian Geographical Reports does not often publish Book Reviews (let alone essays), but this new book on “Renewable Energies and European Landscapes”1is a well-deserved exception to the rule! It is an edited collection of essays gathered together by Frolova (University of Granada, Spain), Prados (University of Sevilla, Spain) and Nadaï (Centre International de Recherche sur l’Environnement et le Développement: CIRED -CNRS, France), based on a series of Workshops organised under the auspices of several agencies (from both Spain and France) in the period from 2007 to the present. In particular, the Spanish Network on Renewable Energies and Landscape (RESERP) began in 2010, with an emphasis on wind and solar power. Published by a well-respected agency, the question can be clearly stated at the outset: Do the editors fulfil their ambitious agenda of providing case studies of value for the emerging research on landscapes of renewable energies of Europe, writ large, i.e. beyond the ‘Southern European’ environment? Or: what is the ‘added value’ of the Southern European cases?
Cage amines in the metal–organic frameworks chemistry
Authors: Sapchenko Sergey A. , Dybtsev Danil N. , Fedin Vladimir P. 
Published: April 2017

Abstract
Nitrogen-rich porous materials have outstanding gas sorption and separation capacity. Using cage amines in the synthesis of metal–organic frameworks is a simple approach for generating the free nitrogen donor centers within the channels of porous materials without the post-synthetic modification. 1,4-Diazabicyclo[2.2.2]octane has a linear arrangement of nitrogen centers and can be used as a linear linker for the design of porous MOF materials. Urotropine has four nitrogen atoms and can act as a tetrahedral four-connected, pyramidal three-connected or bent two-connected linker. Such a diversity of coordination possibilities enriches the structural chemistry of MOFs and allows obtaining the frameworks with unique secondary building units and topology. The presence of cage amines in the structure affects the sorption characteristics of the materials. They demonstrate high selectivity to CO2 and can participate as a heterogeneous base catalyst in the organic reactions. Besides that the cage-amine based metal–organic frameworks demonstrate photoluminescent properties and can be used as nanoreactors for photochemical transformations. These compounds are also an important object of thermodynamic studies helping us better understand the nature of host–guest interaction in the supramolecular systems.
The effect of selected elements of lifestyles on the sitting position
Authors: Gruca M. , Saulicz E. 
Published: April 2017

Abstract
Background: According to the Lalonde’s health field, health is determined in more than 50% by human lifestyles. Nowadays, the sedentary lifestyles are dominant and all types of physical activities discussed by Drozdowski are being gradually ousted from everyday life. This results in maladaptive sitting positions. Therefore, the goal of this study was to evaluate the effect of selected components of lifestyle on sitting position.
Material/Methods: The study examined 372 people who declared a healthy status. The research program involved the questionnaire which concerned selected components of lifestyles and measurements of spinal column to evaluate the sitting position.
Results: The study demonstrated a statistically significant positive effect of time of sitting during the day on the sitting position, i.e. the element of lifestyles which can be directly controlled by study participants.
Conclusions: Of the evaluated components of lifestyles, the most essential effect is from time of sitting during the day. The study demonstrated the need for promotion of healthy lifestyles.
Graphene oxide as a compatibilizer for polyvinyl chloride/rice straw composites
Authors: Bagherinia Mohammad Ali , Sheydaei Milad , Giahi Masoud 
Published: April 2017

Abstract
In this study, polyvinyl chloride (PVC)/rice straw (RS)/graphene oxide (GO) sustainable nanocomposite was prepared using the direct compounding method. Structural, morphological and mechanical properties of fabricated sustainable nanocomposites were compared with unfilled and RS-filled PVC compounds. Mechanical characteristics of PVC decreased with loading RS fibers. The main reason for the mechanical failure of PVC/RS composite is the incompatibility between PVC and RS fibers. GO nanosheets are used here to improve the compatibility between RS fibers and PVC macromolecules. Compared to the neat PVC, maximum strength of the RS/GO-loaded PVC composite increased up to 31%, with incorporating only 1 wt% of GO nanosheets. This enhancement in the mechanical characteristics of PVC/RS/GO nanocomposite can only be due to the role of GO nanosheets as a compatibilizer, as 1 wt% GO loading can only increase the mechanical strength of PVC compounds up to 9%. Fourier transform infrared spectroscopy results are used here to study the nature of these behaviors. It is suggested that the non-covalent and physical interactions between cellulose/hemicellulose portions of RS fibers and GO functional groups result in the enhancement of mechanical characteristics. Consequently, GO can be considered as a new compatibilizer for fabricating high performance PVC-based sustainable nanocomposites.
Improvement in Accuracy of Determining a Vessel’s Position with the Use of Neural Networks Ana Robust M-Estimation
Authors: Czaplewski Krzysztof , Wąż Mariusz 
Published: April 2017

Abstract
In the 21st century marine navigation has become dominated by satellite positioning systems and automated navigational processes. Today, global navigation satellite systems (GNSS) play a central role in the process of carrying out basic navigational tasks, e.g. determining the coordinates of a vessel’s position at sea. Since satellite systems are being used increasingly more often in everyday life, the signals they send are becoming more and more prone to jamming. Therefore there is a need to search for other positioning systems and methods that would be as accurate and fast as the existing satellite systems. On the other hand, the automation process makes it possible to conduct navigational tasks more quickly. Due to the development of this technology, all kinds of navigation equipment can be used in the process of automating navigation. This also applies to marine radars, which are characterised by a relatively high accuracy that allows them to replace satellite systems in performing classic navigational tasks. By employing M-estimation methods that are used in geodesy as well as simple neural networks, a software package can be created that will aid in automating navigation and will provide highly accurate information about a given object’s position at sea by making use of radar in comparative navigation.
This paper presents proposals for automating the process of determining a vessel’s position at sea by using comparative navigation methods that are based on simple neural networks and geodetic M-estimation methods.

Authors: Kollek Wacław , Osiński Piotr , Warzyńska Urszula 
Published: April 2017

Abstract
The paper presents the results of numerical calculations of stress distributions in the gear micropump body for applications in hydraulic systems, especially in the marine sector. The scope of the study was to determine the most favorable position of bushings and pumping unit in the gear pump body in terms of stress and displacement distribution in the pump housing. Fourteen cases of gear pump bushings and pumping unit locations were analyzed: starting from the symmetrical position relative to the central axis of the pump, up to a position shifted by 2.6 mm towards the suction channel of the pump. The analysis of the obtained calculation results has shown that the most favorable conditions for pump operation are met when the bushings are shifted by 2.2 mm towards the suction channel. In this case the maximal stress was equal to 109 MPa, while the highest displacement was about 15μm. Strength and stiffness criteria in the modernized pump body were satisfied.

Published: April 2017

Abstract
Recently we developed [18F] 4-(2-fluoroethoxy)-2H-chromen-2-one as a novel 18F myocardial perfusion imaging radiotracer. It was synthesized in good radiochemical yield (>90%). The total time from radiosynthesis to its purification was less than 40 min, with excellent radiochemical purity (≥99%). It showed good stability over a period of 5 h at room temperature. The partition coefficient (log P) of radiotracer was found to be 2.70, suggesting the lipophilic nature of radiotracer. Ex vivo biodistribution study of radiotracer in normal Wistar rats for 30 min post-injection, demonstrated a good heart uptake (>1.3% ID/g) and favorable pharmacokinetics. Additionally, the radiotracer showed significant excretion (>11% ID) by liver, which is indicative of its rapid clearance. Further, in vivo biodistribution study of radiotracer in New Zealand White rabbit provided the clear PET/CT images of cardiomyocytes and myocardial perfusion. All these experimental findings suggest that [18F] 4-(2-fluoroethoxy)-2H-chromen-2-one could be used as a potential hit for myocardial perfusion imaging.
Is there a Housing Bubble in Turkey?
Authors: Coskun Yener , Jadevicius Arvydas 
Published: April 2017

AbstractThere was a notable housing price inflation in aggregate/local levels in Turkey during the last few years. Although the country’s economic fundamentals remain strong, the probability of a housing bubble is a heated debate among market participants. This timely investigation brings greater clarity to whether the Turkish housing market is in a bubble. The study uses a multi-strand approach to dissect the bubble over the period of Jan. 2010 - Dec. 2014. First, monthly/annual price-to-income and monthly price-to-rent ratios are examined for the national Turkish as well as regional Istanbul, Izmir and Ankara housing markets. Second, an extended CASE and SHILLER (2003) model is applied assessing the interdependence between housing prices and a series of explanatory variables. Lastly, the Right Tail Augmented Dickey-Fuller (Rtadf) test is performed to support the overall analysis. This study finds that neither affordability ratios nor regression estimates support the existence of the bubble in Turkey.
Fees for Advertisements in Public Space Incurred by a Given Bank Brand in Poland
Authors: Płuciennik Monika , Hełdak Maria 
Published: April 2017

Abstract
This article aims to present significant changes in the rates of fees for advertisements on selected bank buildings located in public space, resulting from the implementation of the so-called "Act on Landscape Protection" (Act on amending certain acts in connection with the strengthening of landscape protection tools from 24 April 2015 (2015 Journal Of Laws, item 774). The Act on landscape protection aims to minimize the amount of signboards in city centers. It introduces significant changes regarding (a) fees, (b) the expanded definition of advertisements, and (c) potential revisions and renewal of advertisements. The implementation of the Act causes significant inconveniences and challenges in the process advertising services. The objective of this research is to assess changes in the costs of advertising incurred by banks. More specifically, the research estimated (a) fees incurred by a selected bank brand for signboards placed on all bank branches within the entire country. An altered definition of an advertisement placed in the right-of-way and in public space will cause an increase in the surface of signboards, and, therefore, an increase in fees. In addition, a new type of fee (i.e., advertising fee) will increase the expenses incurred by the bank for the specified objects.
Zinc in the Animal Organism: A Review
Authors: Sloup V. , Jankovská Ivana , Nechybová S. , Peřinková P. , Langrová I. 
Published: April 2017

Abstract
Zinc, as an essential metal, is necessary for the correct function of an organism. It is involved in biochemical processes that affect the immune response of an organism, and it acts as a neuromodulator in the excitatory synapses of the brain. Zinc is also applied in response to stressful stimuli. Zinc is an essential factor of gene expression and is important, at the cellular level, in maintaining the integrity of the cell walls. It influences organism ageing. Zinc is relatively abundant in nature, and it exists in a mineral form and rarely as a pure element. Zinc is used widely in industry and agriculture. In industry, it is utilized mainly in the processing of other metals as protection against corrosion. In agriculture, it is used in fertilizers and chemicals to produce pesticides. In certain areas affected by human activities, its concentrations increase, and large quantities of this metal can get into the food supply. In this paper, we focus on zinc metabolism and homeostasis, with an emphasis placed on the biological function of zinc. This study also deals with zinc deficiency and its effect on health. We also touch on the excessive intake of zinc and its toxicity.
Segmentation of Honey Buyers’ Behaviour by Conjoint Analysis
Authors: Šánová P. , Svobodová J. , Hrubcová B. , Šeráková Petra 
Published: April 2017

AbstractA marketing analysis of Czech consumers’ behaviour when buying honey is discussed from the viewpoint of price, origin, honey type, crystallized sugar, and organic quality aspect. The surveyed target groups of honey consumers, who are examined also with respect to their education level, are from Prague and the Central Bohemian Region. The original premise of this research was the hypothesis that, when buying honey, customers focus primarily on its price and type. This hypothesis was verified by conjoint analysis. The results have shown that consumers are interested primarily in the price and origin of honey. An important parameter for buying honey is its (non)crystallization. Although it does not affect objective quality parameters of honey, it affects the consumers’ subjective perception of honey quality during purchase. Two clusters of honey consumers emerged through cluster analysis: the first cluster focussing on the origin, type, and price/sugar crystallization of honey, and the second interested in the origin, price, and quality of organic honey.

Planejamento urbano e preservação do patrimônio cultural: um olhar para o Conjunto Urbano Santa Tereza, Belo Horizonte
Authors: Ticle Maria Letícia Silva , Pereira Ana Beatriz Mascarenhas 
Published: April 2017

Este artigo pretende problematizar a relação entre preservação do patrimônio cultural e planejamento urbano. É tomado como objeto o bairro Santa Tereza, em Belo Horizonte, protegido como conjunto urbano pela política de preservação do patrimônio cultural do município. Também serão discutidas questões relativas à prática do planejamento urbano, que envolve a regulamentação dos usos do espaço e suas funções econômicas, políticas e sociais. O processo, que envolve diversas disciplinas, como engenharias, arquitetura, história, sociologia, política e outras, é geralmente muito mais orientado para a dimensão física das idades, negligenciando seus desdobramentos sociais. As políticas patrimoniais intencionam preservar as complexas associações entre as dimensões material, social e imaginativa. Entretanto, incorporadas ao planejamento urbano, constituem um grande desafio, considerando seu dinamismo e sua interface com a manutenção de subjetividades.
