Oral Ingestion Risks of Heavy Metal Accumulation at Top Soils of Automobile Workshops in Owerri Capital City of Imo State, Nigeria
Authors: Agomuo Emmanuel N. , Amadi Peter U. 
Published: July 2018

Abstract
This investigation was carried out to assess the heavy metal concentrations and health risks associated with automobile workshops in Owerri Metropolis. Using an Atomic Absorption Spectrophotometer, soil samples from Orji Mechanic Village (OMV), Naze Mechanic Village (NMV), New Market Automobile Workshops (NMAV), Matrix Mechanic Yard (MMY) and Alvan Mechanic Yard (AMY) were assayed for Silver (Ag), Cobalt (Co), Nickel (Ni), Mercury (Hg), Lead (Pb), Arsenic (As), Chromium (Cr) and Cadmium (Cd) concentrations. The result showed that at majority of the sites, the Ag, Pb, As, and Cd levels exceeded their baseline values, whereas the Ni and Co levels were equivalent to those of their baselines, at some sites. Soil samples at MMY were the most acidic while that of NMAV was the most alkaline. The pollution models indicated very high Ag contamination at OMV, NMV, and NMAV while all the sites showed very high contamination of Pb and Cd, and no Co, Ni, Hg, and Cr pollution was recorded for all the sites as shown by their Igeo values. The result for the enrichment factor showed anthropogenic sources of deposition of these heavy metals at all the sites. From the risk assessment models applied, none of the contaminated sites showed an estimated daily intake, hazard quotient, and total hazard index beyond the reference values, with Pb found to possess the greatest potentials of toxicity. This study has shown the necessity to periodically monitor and apply measures that can halt the environmental decay, occurring at the automobile workshops.
Impact of Thiocyanate on the Catecholase Activity of Cu(II) and Fe(III) Complexes of 2-((4-(2-Hydroxy-4-Methylbenzyl)Piperazin-1-YL)Methyl)-5-Methylphenol (A Mannich Base)
Authors: Ayeni Ayowole O. , Watkins Gareth M. 
Published: July 2018

Abstract
Four metal complexes viz Cu(II) and Fe(III) with or without thiocyanate have been synthesized from a Mannich base prepared by a simple synthetic route. These complexes were characterized by elemental and spectroscopic techniques. Bonding modes of the thiocyanate group with the metal complexes as studied by infrared spectroscopy revealed the presence of bridging N- and S- bonding modes. Detailed kinetic studies of these complexes were carried in the evaluation of their catecholase activity. The Fe(III) complex demonstrated the highest catalytic activity using 3,5-di-tert-butyl catechol (3,5-DTBC) as substrate with a turnover rate (kcat) of 112.32 h−1.

Published: July 2018

Abstract
For the first time, a survey about agricultural land focusing on the partitioning of the Pb, Cd, and Zn to the rural part of Mitrovica in northern Kosovo was made. Kosovo’s Mitrovica is one of the main industrial sites in the former Yugoslavia and a world-class mining district in Europe. The process of obtaining metals dates since 1927. From this year until 2000, the technological process of acquisition/obtaining has been accompanied by environmental pollution by creating waste landfills. These landfills are located on the outskirts of the city of Mitrovica at a distance from 1 to 4 km. In this area high levels of heavy metals in air, water, and earth were noticed. Therefore, these metal residues have a particular impact on air, earth, water, and effects on plants, animals and humans health. This situation became alarming; therefore in 2000 the production process was discontinued. During the period from 2000 to the present day, there is noticed a change of nature. Residents of the area have begun to work on agricultural lands without realizing the potential risk coming up. Despite the stagnation of industrial production, environmental pollution continues even further, especially from the landfill generated by industrial wastes. Widespread and very visible contamination mainly from Pb, Zn, Cd were found on the ground, with the highest concentrations measured near the Zveçan smelter. A significant amount of Cd, Pb, and Zn in contaminated soils/ground was quite movable/changeable, suggesting that these elements may be readily available for plants and soil/ground organisms. The main objective of this work is to address this pollution and take measures for education and information.

Published: July 2018

Abstract
Stress-strain state of isotropic plate with rectilinear through-crack at combined action of bending and tension, realized by applying distributed forces and bending moments at infinity, the vectors of which are parallel and perpendicular to the crack, is investigated. Under the influence of the internal stress the crack faces contacts on area of constant width near the upper base of plate, and plastic zones forms in its tips. Using methods of the theory of complex variables, complex potentials plane problem of elasticity theory and the classical theory of plates bending, solving of the problem is reduced to the set of linear conjugation problems and their analytical solution is built in a class of functions of limited plastic zones in the crack tips. The conditions of existence of the solution of the problem in these terms are determined. Using Treska plasticity conditions in the form of surface layer or the plastic hinge, the length of plastic zone and crack opening displacement are found analytically. Their numerical analysis for various parameters of the problem is conducted.
Changes in alpine vegetation over 50 years in the Western Tatras (Slovakia)
Authors: Palaj Andrej , Kollár Jozef 
Published: July 2018

Abstract
This paper examines changes in alpine vegetation over 50 years in the Western Tatras part of the Western Carpathians Mountains in Slovakia. We focus on the following most widespread vegetation types: subalpine to subnival grasslands (alliance Juncion trifidi Krajina 1933), snowbed vegetation (alliance Festucion picturatae Krajina 1933) and dwarf-shrub vegetation (alliances Loiseleurio-Vaccinion Br.-Bl. in Br.-Bl. et Jenny 1926 and Vaccinion myrtilli Krajina 1933). The historical 1971–1977 sampling dataset was re-sampled in 2016–2017 and our research is based on a comparison of 40 pairs of these relevés. Herein, we studied (i) changes in species frequencies; (ii) changes in phytodiversity and site conditions using estimates of Ellenberg’s eco-indices and (iii) comparison of historical and current relevés over time using the nonmetric multidimensional scaling gradient analysis (NMDS) ordination method. The frequency curves reveal differences; especially in the most frequent species at 37.5−80%, which reach higher values in the current data. The higher 7.5−25% value of medium-frequent species in the historical relevés indicates progressive homogenisation of the examined vegetation. In addition, the Shannon-Wiener index of individual vegetation types revealed no significant differences in diversity or average number of species. The historical relevés included 75 species while 74 were confirmed in the current data. Statistically significant differences were determined in light factor for all three vegetation groups. This was due to the retreat of some light-demanding species. While NMDS indicated changes in Festucion and Vaccinion relevés over time, the Juncion group relevés did not follow this trend, thus confirming their high stability. The observed changes between current and historical data are attributed to changes in climate and altered land use with the cessation of grazing.
Quality of life in the city, quality of urban life or well-being in the city: Conceptualization and case study
Authors: Murgaš František , Klobučník Michal 
Published: July 2018

Abstract
Quality of life research responds to the growth of urbanization in the world by increasing the focus on the quality of urban life; however, the dominant applied research tends to be without conceptualization of the quality of urban life. The aim of this paper is to answer the question whether the quality of urban life exists as an original, separate part of the concept of quality of life, or whether only the quality of life or the well-being of a certain city exists. The authors argue that the quality of urban life exists as an original category of quality of life and their beliefs are based on the fact that it can be measured separately. The quality of urban life is holistic, co-existing with the quality of life. The city from the point of view of quality of life research is a place, and the quality of urban life is the satisfaction with life in a city and the quality of place in it. This approach is applied to the quality of urban life and its measurement in the city of Liberec. The results are implications for policy-makers and urbanists.
Challenges of BIM technology application in project planning

Published: July 2018

Abstract
The study aimes at identification of the difficulties in choosing the correct concept of the main building process. The use of a proper BIM design may help the user avoid mistakes and make the building process faster as well as less financial resource intensive. The authors focused on literature review, analysing the difficulties of the BIM design software technology in construction project planning. The biggest flaws in BIM design are inherent in three building process stages: 1) the preparation of a building investment project, and the analysis of the existing situation; 2) the preparation of the building execution technology project; 3) the existing standard processing and information collection in building exploitation period. The analysis shows a persistent need for a deeper BIM design research, to improve information interchange formats that would ensure as much design information saved as possible with ensured feedback. As well as in BIM design, the software packages must be improved by supplementing them with deficient tools or programme codes. After the research of BIM design software, it was determined that architectural, constructional and MEP programs work best interdependently and get analysed the most. These programs work best as they make the least number of mistakes when the model is created in one setting and has many tools. This type of design software data is kept internally, and they are converted into IFC or other information interchange format. Without changing the format, the data is not lost, and this is the reason behind fluent information interchange.
Intellectual property management in startups — problematic issues
Authors: Baran Agnieszka , Zhumabaeva Asel 
Published: July 2018

Abstract
This paper describes the most important problems related to the management of intellectual property in startups. Startups have become an inseparable element of the innovative economy. Many of these companies base their development on intellectual capital and innovations. In this context, it is extremely important to legally secure the innovations and protect intellectual property. These activities can often be the decisive factor in the development of startups. This article aims to identify, analyse and evaluate the most important issues related to the management of intellectual property in startups. The first part of this paper presents the performed literature review, which mainly concerns the definition of innovation, the state of entrepreneurship in Poland, and the definition of a startup. The second part of the article deals with the main problems related to the management of intellectual property in startups. It is divided into three issues: underestimating the importance of intellectual property, the lack of intellectual property management strategies in startups and financial challenges of startups. The main results of the research indicate that many startups still have low awareness of what is intellectual property and what can be the consequence of using exclusive rights of others. The protection of intellectual property should become one of the elements of business strategies. However, startups find that the creation of the strategy and its implementation is rather expensive.

Published: July 2018

Abstract
The aim of this study was to evaluate the potential protective role of Agrimonia eupatoria L. in heavy metal induced nephrotoxicity. Rabbit kidney epithelial cells (RK13) were used as the model cell line. They were exposed to three different heavy metal compounds: cadmium chloride dihydrate CdCl2.2H2O (15 and 20 mg.l−1), potassium dichromate K2Cr2O7 (1, 10 mg.l−1), and zinc sulfate heptahydrate ZnSO4.7H2O (50, 150 mg.l−1) simultaneously with agrimony (ethanolic extract, 100 mg.l−1). The cell response was recorded using the xCELLigence system or real-time cell analysis (RTCA) as a cell index (CI) and expressed as cell adherence (%) compared to control cells without treatment. The potential nephroprotective effects were recorded in cells treated with chromium (1 a 10 mg.l−1) and agrimony, where the cell adherence increased from 95.11 ± 11.25 % and 7.24 ± 0.33 % to 103.26 ± 1.23 % and 68.54 ± 4.89 % (P < 0.05) respectfully and also with a combination of agrimony and zinc (150 mg.l−1), where the adherence increased from 57.45 ± 1.98 % to 95.4 ± 6.95 %. During the cell exposure to cadmium in combination with agrimony, the protective effect was not recorded; the adherence of cells was even decreased (P < 0.05).
About the Ability to Be in Two Places at Once
Authors: Stemberger Gerhard 
Published: July 2018

Summary
In 1915 the Danish psychologist Edgar Rubin describes in his famous work on figure-ground perception, the phenomenon that when you look attentively at a picture, a second, virtual ego arises, breaking away from the viewer-ego to wander around in the picture along the contours of the depicted. In 1982, German Gestalt psychologist Edwin Rausch expanded this observation of the emergence of a second phenomenal ego to the conclusion that not only does a second phenomenal ego emerge, but with it a second phenomenal total field, ie a second phenomenal world with its own phenomenal ego and an own phenomenal environment of this ego.
Several years ago, I proposed a multi-field-approach in psychotherapy building on this research. This approach involves three levels:
First, the level of phenomenological observation and psychological analysis of the conditions that determine the formation of such a second total field (and even further total fields), regardless of whether this occurs spontaneously or intentionally or as a result of external influences.
Second, the level of explanation of various psychic processes, which in the field of psychotherapy have been explained so far mainly on the basis of depth psychology, and the conceptualization of the therapeutic situation and therapeutic processes from a Gestalt psychological perspective.
Third, finally, the level of practical application of such insights on the development of appropriate procedures and interventions that can promote or defer the emergence of such second or multiple fields in psychotherapy.
The present article introduces the multi-field approach, especially at the first level, and refers to research and discussion on mind wandering, imagining, daydreaming and dissociation.
Productive Thinking in Place of Problem-Solving?
Authors: Lumbelli Lucia 
Published: July 2018

Summary
Why and how is the Gestalt theorists’ concept of productive thinking particularly suitable for being applied to the educational question of how student motivation can be encouraged, thus providing an important condition for self-regulated, intrinsically motivated learning?
An answer to this question has been sought using an approach to the fostering of text comprehension ability, based upon the features specific to productive thinking, originally identified by Wertheimer (1945) and Duncker (1935).
Firstly, these specific features are dealt with and their educational implications compared with those deriving from the definitions of problem-solving used most frequently in educational research. Secondly, an analysis is made of the process by which the features specific to productive thinking are turned into the conditions for a kind of text analysis suitable for designing an instructional project aimed at enhancing text comprehension ability and, at the same time, encouraging intrinsic motivation and self-regulation on the part of the learner. Thirdly, an educational project centred on the thinking-aloud poor reader is described, where thinking aloud and reflection–response are combined in order to guarantee the maximum level of intrinsic motivation. In the concluding section, the most important features of the project are discussed in relation to reciprocal teaching and scaffolding.
The Primary Intersubjectivity and the Gestalt Theory
Authors: Arfelli-Galli Anna 
Published: July 2018

Summary
For the study of the first year of life, Sander, Stern, and Gomez each chose the adult–infant relationship as the unit of analysis; they followed its development, respectively, in moments of meeting, in the proto-conversation and in the focus of attention. The authors explicitly refer to the Gestalt theory and support the need to interpret the behavior of the child as part of a wider context, as the experiences of a person in relation (Galli, 2010) since birth.
Hier bin Ich: Wo bist Du?
Authors: Chiandetti Cinzia 
Published: July 2018

Summary
Since its first description, the imprinting phenomenon has been deeply investigated, and researchers can nowadays provide profound knowledge of its functioning. Here, I present how this peculiar form of early exposure learning can be used as a strategy to study animal cognition. Starting from imprinting as a social trigger for the domestic chick (Gallus gallus) and combining it with the unique possibility of accurate control of sensory experiences in this animal model, I present evidence that in artificial environments, imprinting serves as a rigorous test of the core domains of cognition. Whether basic cognitive concepts are already present at birth or whether they need extensive experience to develop are questions that can be addressed in precocial birds and still, following the tradition of the seminal works made by Lorenz, can inform on human cognitive processing.
“The Year Replaces the Year.”1 Udmurt Spring Ceremonies among the Non-Christian Udmurt: An Ethnographic Analysis of Contemporary Ritual Life (On Materials from Varkled-Böd’ya Village)
Authors: Toulouze Eva , Anisimov Nikolai 
Published: July 2018

Abstract
The authors had the opportunity, during their fieldwork, to attend spring rituals in Varkled-Böd’ya village. The week before the Great Day (Bydjynnal, coinciding with Orthodox Easter) is a dense ritual week: there are young people to be initiated, boys first and girls at the concluding ritual, who thus become adults; there are evil spirits to be chased away from the space of the living; there are kin relations to be reinforced through reciprocal visits, prayers and ritual deeds. These four rituals are the focus of this article, which provides an ethnographic account as well as a general analysis of the critical dimensions observed.
A Demand - and Supply- Side Constrained Model for Liquidation Value and Related Exposure Periods
Authors: Michaletz Vladimir B. , Artemenkov Andrey 
Published: July 2018

Abstract
Two problems appear to be most topical in conjunction with mortgage valuation practices during an economic crisis: the assessment of sustainable long-term mortgage values and the assessment of liquidation discounts to prevailing market values which would provide for the most advantageous liquidation/quick sale strategy. This paper addresses the latter issue, which has traditionally proven intractable to analytical modeling. Apart from reviewing some research devoted to the subject of liquidation value modeling, predominantly from the Eastern European perspective, where this issue has, for years, commanded a particular economic interest, this paper synthesizes the best features of this research and builds on it to propose its own model, which lays equal emphasis on both the sellerside and demand-side perspectives. The first perspective accounts for the financial interests of a lender in forced sale disposals, while the latter perspective engages economic analysis on the side of market feasibility of identified efficient lender disposal strategies. By negotiating both perspectives, an optimal analytic solution to the issue of liquidation value discounts can be obtained. This is achieved by what we call a SI-MI framework which is developed throughout the paper.
We also adapt this framework specifically to the mortgage banking context where we use it to bring to light some rarely discussed linkages between the LTV policies of a bank and its mortgage liquidation strategies. This also allows us to propose a model and an LTV formula which can help organize thinking about optimal LTV policies in credit issuing processes.
We hope that, with the re-appearance of liquidation value basis/premise of valuation as a recognized international basis of valuation in the new edition of the International Valuation Standards (IVS 2017), the findings of this paper will become topical.
Rules and Conditions for Placing Advertisements in Public Space Based on Examples of Selected Polish Cities
Authors: Płuciennik Monika 
Published: July 2018

Abstract
The changes in law introduced by the so-called “Act on Landscape Protection” (Act on amending certain acts in connection with the strengthening of landscape protection tools of 24 April 2015) obliged local territorial self-government units to define the rules and conditions regarding the placement of street furniture, signboards and other advertisement carriers and fencing. The aim of the discussed local legislation act is, in particular, to define urban space used for the display of advertisements along with the determination of the size, quality standards and type of construction materials from which signboards and other advertising devices may be produced. The determination of urban space for the display of advertisements is a broad and multi-faceted issue. There are certain limitations that hinder or prevent the placement of posters, banners, signboards or advertising panels in public space. The study presents the measures taken by local territorial self-government units with respect to the placement of advertisements in selected Polish cities and attempts to compare and evaluate the rules and conditions for placing signboards and advertising devices in public space.
