Spectrophotometric Determination of Trace Concentrations of Copper in Waters Using the Chromogenic Reagent 4-Amino-3-Mercapto-6-[2-(2-Thienyl)Vinyl]-1,2,4-Triazin-5(4H)-One: Synthesis, Characterization, and Analytical Applications
Authors: Alharthi Salman. S. , Al-Saidi Hamed. M.
Published: June 2020

A simple, selective, and inexpensive spectrophotometric method is described in the present study for estimation of trace concentrations of Cu2+ in water based on its reaction with chromogenic reagent namely 4-amino-3-mercapto-6-[2-(2-thienyl)vinyl]-1,2,4-triazin-5(4H)-one (AMT). The reaction between copper(II) ions and AMT reagent gives [Cu(L)(NO3)(H2O)2]•H2O complex, where L represents AMT molecule with NH group. The formed complex exhibits a sharp, and well-defined peak at λmax = 434 nm with a molar absorptivity (ε) of 1.90 × 104 L mol−1 cm−1, and Sandell’s factor of 0.003 μg mL−2. Absorbance of the [Cu(L)(NO3)(H2O)2]•H2O follows Beer’s law over a 0.7–25 μg mL−1 range with a detection limit of 0.011 μg mL−1. Validation of the submitted method was established by estimating Cu2+ in certified reference materials and actual sea and tap water samples. The results are compared with data obtained from copper concentration measurements using ICP-OES. The chemical structure of the Cu(II)-AMT complex was fully characterized by FT-IR, SEM, EDX, TGA, and ESR techniques.
Calculating the Interface Flow Limits for the Expanded Use of High-Voltage Direct Current in Power Systems
Authors: Han Sangwook
Published: June 2020

Although loads are increasingly becoming concentrated in metropolitan areas, power generation has decreased in metropolitan areas and increased in nonmetropolitan areas; hence, power transmission must occur through interface lines. To achieve this, additional transmission lines must be secured because the existing interface lines have reached their large-scale power transmission limits. The Korea Electric Power Corporation has installed many high-voltage direct current lines, thereby impacting the determination of interface power flow limits. These serve as the basis for system operations. However, knowledge of operating high-voltage direct current lines as a simple transmission line in a single power system is lacking. The effects of high-voltage direct current and its related parameters for interface flow limit analysis remain unclear. Furthermore, whether high-voltage direct current should be included in the selection of the interface lines that serve as the basis for interface flow remains unclear. In addition, whether the high-voltage direct current line faults should be included in the contingency list for determining the interface flow limits has not been considered. Additionally, it has not been determined whether to operate the DC tap when performing the simulation This study addresses these issues and determines the conditions that are necessary for determining the interface flow limits when a high-voltage direct current transmission facility has been installed in a land power system. The results conclude how to reflect the above conditions reasonably when performing the interface flow limit analysis on a system that includes the HVDC lines.
Miniaturization of a Koch-Type Fractal Antenna for Wi-Fi Applications
Authors: Tumakov Dmitrii , Chikrin Dmitry , Kokunin Petr
Published: June 2020

Koch-type wire dipole antennas are considered herein. In the case of a first-order prefractal, such antennas differ from a Koch-type dipole by the position of the central vertex of the dipole arm. Earlier, we investigated the dependence of the base frequency for different antenna scales for an arm in the form of a first-order prefractal. In this paper, dipoles for second-order prefractals are considered. The dependence of the base frequency and the reflection coefficient on the dipole wire length and scale is analyzed. It is shown that it is possible to distinguish a family of antennas operating at a given (identical) base frequency. The same length of a Koch-type curve can be obtained with different coordinates of the central vertex. This allows for obtaining numerous antennas with various scales and geometries of the arm. An algorithm for obtaining small antennas for Wi-Fi applications is proposed. Two antennas were obtained: an antenna with the smallest linear dimensions and a minimum antenna for a given reflection coefficient.
Simulation Study on Reservoir Souring Induced by Injection of Reservoir Brine Containing Sulfate-Reducing Bacteria
Authors: Sugai Yuichi , Owaki Yukihiro , Sasaki Kyuro
Published: June 2020

This paper examined the reservoir souring induced by the sulfate-reducing bacteria (SRB) inhabiting the reservoir brine of an oilfield in Japan. Although the concentration of sulfate of the reservoir brine was lower than that of seawater, which often was injected into oil reservoir and induced the reservoir souring, the SRB inhabiting the reservoir brine generated hydrogen sulfide (H2S) by using sulfate and an electron donor in the reservoir brine. This paper therefore developed a numerical simulator predicting the reservoir souring in the reservoir into which the reservoir brine was injected. The results of the simulation suggested that severe reservoir souring was not induced by the brine injection; however, the SRB grew and generated H2S around the injection well where temperature was decreased by injected brine whose temperature was lower than that of formation water. In particular, H2S was actively generated in the mixing zone between the injection water and formation water, which contained a high level of the electron donor. Furthermore, the results of numerical simulation suggested that the reservoir souring could be prevented more surely by sterilizing the SRB in the injection brine, heating up the injection brine to 50 °C, or reducing sulfate in the injection brine.
Multi-Criteria Decision Making of Contractor Selection in Mass Rapid Transit Station Development Using Bayesian Fuzzy Prospect Model
Authors: Cheng Min-Yuan , Yeh Shu-Hua , Chang Woei-Chyi
Published: June 2020

In Taiwan, the most advantageous tender in governmental procurement is the selection of a general contractor based on a score or ranking evaluated by a committee. Due to personal, subjective preferences, the contractor selection of committee members may be different, causing cognitive difference between the results of the members’ selection and the preliminary opinions provided by the working group. Integrated, multi-criteria decision making techniques, combined with preference relation, Bayesian, fuzzy utility, and prospect theories are used to assess factors weighing up the duration/cost/quality, probability of external information, and utility function system. The paper proposes a Bayesian fuzzy prospect model for group decision making, based on probability and utility multiplied relation, and taking the sustainable development factors into consideration. This study aims to provide committees with an objective model to select the best contractor for public construction projects. The results of this study can avoid the lowest bidder being selected; besides, the score gap of contractor selection can be increased, and the difference between the top three contractors’ scores can be decreased as well. In addition to proposing an innovative decision-making system of contractor selection and an index weight-assessing system for sustainable development, this model will be widely applied and sustainably updated for other cases.
HISTORICAL TRANSFORMATIONS OF HERMENEUTICS M. HEIDEGGER
Authors: Dubinina Vira
Published: June 2020

Hermeneutics of presence, developed by M. Heidegger, and possible ways of its further transformation are considered. This tendency was embodied and developed in the project of philosophical hermeneutics H.-G. Gadamer, who focuses not on the analytics of presence, but on the language as a horizon of meaning and understanding. A comparative analysis of these theories shows that the understanding of hermeneutics as an ontological interpretation of presence is completed not only in the framework of ontological discourse, but also in the representation of language as an independent agent, which is also the most developed topos of existence.
The analytics of presence is the main content of Heidegger’s main work, and at the same time it should become the basis of the fundamental ontology, which grows directly from such hermeneutics and, in a sense, is its substantive mode. Such a theory is an understanding that is carried out not as an act of thinking, but as a way of staying, a special Dasein modus, which is given not so much epistemologically as existentially.
Although Gadamer lacks the required hermeneutic analytics of the language, he never departs from his postulate of the linguistic nature of understanding. For him, the soil on which human existence is built as understanding is initially language, while Heidegger comes to language through speech, which is seen as the existential-ontological foundation of language. Language, according to Gadamer, is an a priori condition for any act of understanding, the space for its implementation and, at the same time, the result, expressed in the total “stipulation” of the world by the word.
THE INTERACTIONS BETWEEN SPIRIT, SOUL AND BODY IN RELIGIOUS AND ANTHROPOLOGICAL SEARCHES OF V.F. VOINO-YASENETSKY
Authors: Zaluzhna Alla , Veremeichyk Serhii
Published: June 2020

The essence of human nature in the context of the work of St. Luka Krymskiy "Spirit, soul and body" is showed up in the form of a pyramid, the top of which is headed by the spirit and at the heart of which is the material body. In this direction it is determined that the spirit itself is the true essence of man, and the soul and body only act as intermediary between him and the world, shaping and directing him in his development towards good or evil. The interaction between them occurs at the point of the act of human consciousness. It should be noted that, according to St. Luke, the spirit is only a partially autonomous unit, and can only exist independently from the body and the soul.

A 15 C’s Pathway of Sustainability in Environmental Health Management & The Crucial Role of Higher Education Institutions
Authors: Maipas Sotirios
Published: June 2020

Manmade environmental degradation has created an unsustainable status quo posing many known and yet unknown environmental health threats. Innovation, which may be considered as a function of time, location, and explicit and tacit knowledge acquisition, is essential for the effective and sustainable management of environmental health issues. The following series of C’s may function as a pathway towards sustainability in environmental health management: (1) Consciousness of the urgency, (2) Comprehension of the complexity, (3) Confidence in our ability to change, (4) Capacity-building for decision-making, (5) Cooperation among stakeholders, (6) Carbon footprint reduction, (7) Circular economy adoption, (8) Corporate sustainability, (9) Creativity (Creative thinking and action), (10) Creation of resilient and adaptive communities, (11) Creation of sustainable living environments for all social groups, (12) Creation of new explicit and tacit knowledge, (13) Communication of the new knowledge, (14) Curriculum updates, and (15) Crisis management. Apart from the emerging teaching and research priorities, the proposed pathway requires a strategic higher education institutions’ contribution to the necessary societal transformation towards sustainability. Higher education institutions could play a crucial role in all the described steps of this 15 C’s pathway and in the interconnections between them. Each step may offer emerging opportunities for innovative planning and action towards a more sustainable future. However, further research and pilot applications are necessary for the evaluation of the proposed theoretical model.
Representing Europe in Times of Crisis
Authors: Takas Emmanouil , Prodromitis Gerasimos , Papastamou Stamos
Published: June 2020

This study focuses on the exploration of the political discourse regarding the voting of the three Memoranda in Greece, at a period characterized by the concept of "crisis", that triggered violent processes of redefining the social environment. As Greek society was under the strain of European stability, it was called upon to fully comply with the European imperatives of "development" and "competitiveness". In this context, the political discourse formed central representations and each political party tried to increase its sphere of influence. This study approaches the notion that the representations in the political discourse are formed under terms of strategic communication. Further, such representations aspire to influence four parallel audiences: the intra-party audience, the intra-parliamentary audience, the wider intrastate social audience and the international audience (European partners, main European political actors, international organizations, political actors and the media).  To investigate the way in which the Greek political system constructs the representation of Europe in the context of the Memoranda, the official parliamentary transcripts regarding the voting of the first, second and third memoranda were analysed. The analysis was based on both the quantitative and the qualitative approach, using the Iramuteq open source software (Ratinaud, 2009). The central findings of this thesis underline the way in which the Greek political system established Greece's relationship with Europe in terms of dependence, how Greece gradually complied with European imperatives and internalized the concept of "Debt".
Situational Factors and Increased Workplace Burnout
Authors: McFadden Kiahni , Altamirano Michael
Published: June 2020

Workplace burnout has been on the rise in recent years, and stress is a significant contributor. The World Health Organization (WHO) considers burnout as an “occupational syndrome,” which is often a result of chronic stress. There has been an emergence in topic related studies, a need for clarity, diagnosis, and treatment regarding workplace burnout. The need for continual research is essential for further understanding of this phenomenon. Burnout has two contribution factors; situational factors and individual factors that contribute to stress. Situational factors include job demands and resources. Individual factors include financial situations and individual personality. These factors can affect the way persons respond to overloaded work responsibilities. This condition often results in a reduction in professional efficacy and productivity. This research explores workplace burnout in employees under the age of 50, often referenced to as younger employees and the relationship between workplace burnout and situational factors. Exploring the effects of why workplace burnout has increased in recent years could lead to a better understanding of the condition, and the suggestion of measures to reduce burnout. The research of burnout would be beneficial toward the continued understanding of global workplace behavior as it relates to the topic of stress management.

Explanatory notes to the Geological map of Greenland, 1:500 000, Humboldt Gletscher, Sheet 6
Authors: Dawes Peter R.
Published: June 2020

These explanatory notes cover the map region bounded by latitudes 78°N and 81°N and longitudes 56°W and 74°W, with geology shown on the land areas between Nares Strait - the seaway between Greenland and Ellesmere Island, Canada - and the Inland Ice. The bedrock geology is composed of Precambrian and Lower Palaeozoic provinces that continue across Nares Strait into Canada. Map units and mineral occurrences are described in general terms and are proceeded by sections on physical environment, logistics, data sources and geoscientific research. The notes are aimed at the practical user and a guide for further reading.

The bedrock is composed of three provinces separated by unconformities, each representing a hiatus of c. 500 Ma during which basic dykes were emplaced. The Palaeoproterozoic Inglefield mobile belt, forming the crystalline shield, is an E-W-trending belt of deposition and orogeny characterised by polyphase magmatism, deformation and high-grade metamorphism. Clastic deposition, with magmatism at c. 1985 Ma, are the oldest events recorded, followed by the accumulation of the Etah Group (carbonate, pelitic and psammitic sediments with supposedly coeval mafic and ultramafic rocks) between 1980 and 1950 Ma ago. These rocks were intruded 1950 to 1915 Ma ago by the Etah meta-igneous complex, that records polyphase plutonism (intermediate to felsic, with some basic and magnetite-rich rocks), followed by deformation and partial melting producing granites 1785 to 1740 Ma ago. The Mesoproterozoic Thule Basin, defined by the unmetamorphosed and little deformed Thule Supergroup, records sedimentation and basaltic volcanism at least as old as 1270 Ma. The faulted, north-eastern basin margin shown on the map preserves the passage from the basinal sequence to a relatively thin platform succession invaded by basic sills. The Palaeozoic Franklinian Basin is represented by a homoclinal Cambrian to Silurian shelf carbonate succession and a major Silurian reef complex, with coeval siliciclastic slope deposits. The map region includes the classical area for Franklinian stratigraphy, now composed of 29 formations and four groups - Ryder Gletscher, Morris Bugt, Washington Land and Peary Land Groups. The only younger units preserved in the map region are widespread Quaternary deposits, an isolated outcrop of coarse-grained fluvial deposits (Bjørnehiet Formation) and non-carbonised wood erratics of Neogene age.

Five mineral occurrence types are shown on the map: in lithologies of the Inglefield mobile belt, sulphide-graphite rust zones, a magnetite deposit and copper-gold mineralisation and in the Franklinian Basin, commercially drilled, zinc-lead-silver and zinc-lead-barium mineralisations. The basic ingredients of a petroleum model exist in the Franklinian Basin but prospectivity is low.

Economic Impact of Public Expenditure in The Gambia
Authors: Roberts Thomas , Cabral François J. , Coly Samuel Maxime
Published: June 2020

The impact of public expenditure on the productive sectors (agriculture, industry, and service) in The Gambia, is analyzed within the framework of a Dynamic Computable General Equilibrium (DCGE) model. The model is applied and calibrated to assess the impact of a 10% increase in public expenditure on economic growth and welfare over five years. The results indicate an increase in GDP and value-added, mainly as a result of growth in the service sector.Also, an expansion of the service sector leads to the migration of jobs to the rural areas, which will consequently enhance rural labour income. A significant finding is that general public expenditure on agriculture may not get the desired result for poverty reduction, specifically in rural areas. As a result, public agricultural spending should be targeted across various agriculture sub-sectors, such as, irrigation, among others. The Government of The Gambia (GoTG) should also prioritize investment in the service sector, given that it has immense potentials in enhancing the livelihoods of Gambians in rural areas.
Development of Analytical Model for a Vertical Single U-Tube Ground-Coupled Heat Pump System
Authors: Tarrad Ali H.
Published: June 2020

An analytical model was built to study the thermal design of a single vertical U-tube coupled heat pump under steady-state conditions. It was based on the philosophy of U-tube replacement by an equivalent thermal resistance situated between the heat transfer medium that flows inside the tube and the borehole boundary. An obstruction factor was introduced to account for the reduction of heat flow from or to a tube in the borehole due to the presence of the second leg of the U-tube. Two Copper U-tubes with wall factors of (12.5) and (14.29) were implemented to comprise several borehole configurations to verify the present work. The shank spacing was ranged between (2) and (4) times the U-tube outside diameter producing shank spacing to borehole diameter ratio range of (0.29-0.59). The model was utilized for the assessment of DX ground heat exchangers works as a condenser for cooling purposes. Reducing of the tube spacing to tube outside diameter ratio from (3.3) to (2) for both tube wall factors showed a rise for the borehole thermal resistance in the range of (22-54)% and (26.5-28)% predicted at wall factors of (12.5) and (14.29) respectively.

Responders (decrease in LVESV ≥15%) and non-responders (decrease in LVESV ˂15%) were identified.

Results: the number of responders was 26 (65%). Initial set of variables included: age, left ventricular ejection fraction (EF), systolic pressure in the pulmonary artery, right ventricle size and NT-proBNP, СRP, ММР-9, CYSTATIN. According to logistic regression analysis, a model was created: F=3.231 + 0.344 х EF - 3.479 x CYSTATIN - 0.039 х ММР-9 - 0.638 х CRР. Prediction of response to CRT (P) was carried out using the equation: Р=1/(1+е(-F)); a less than 0.696 p-value was associated with membership of non-responders group; p-value greater than or equaled to 0.696 was associated with group of responders. The specificity of the model was 92.9%, sensitivity - 83.3%, AUC=0.952 (р˂0.001).

Conclusions: the proposed model, based on assessment of left ventricular EF and laboratory data, that reflect key mechanisms of development and progression of CHF - immune inflammation, fibrosis, renal dysfunction, suggests a possible response to CRT.

Aim: to assess morpho-functional properties of left ventricle (LV) in patients with superresponse (SR) to CRT using the helical ventriсular band concept (HVB).

Materials and methods: 56 patients were examined (mean age 54.0±9.9 years) at baseline and during follow-up visit: 48.8±25.6 months. Patients were divided into groups: I group (n=34) with decrease of LV end-systolic volume (ESV) ≥30% (superresponders) and II group (n=22) - decrease of LV ESV ˂30% (nonsuperresponders).

Results: apical loop descendens segment (DS) and ascendens segment (AS) of HVB were evaluated according to the concept of F. Torrent-Guasp et al. According to the logistic regression mechanical interventricular delay (MID) (OR 1.072, 95% CI 1.017-1.131; p=0.01) and systolic thickening fraction (STF) of interventricular septum (IVS) DS (OR 0.944, 95% CI 0.895 - 0.995; p = 0.033) had an independent relationship with CRT SR. According to the ROC analysis the sensitivity and specificity of this model were 72.7% and 66.7% (AUC=0.769; р=0.001). AS STF of IVS was higher in SR (22.5 [0.0;40.0]% и 0.0 [0.0;25.0]%; р=0.005). The survival rate in group I was 85.1%, in group II was 63.6% (Log-Rank test p=0.019).

Conclusion: SR is associated with a higher AS STF of IVS, higher MID, also with a higher survival rate.

Aim. The potential distribution of the cardioelectric field on the body surface during the initial atrial activity and the sequence of depolarization of the atrial subepicardium in rats with experimentally induced pulmonary hypertension were compared. This work is devoted to non-invasive detection of arrhythmogenic foci of atria by using the cardioelectric field on the body surface during experimental pulmonary hypertension.

Materials and methods. The method of cardioelectrochronotopography has been used to study the electric field of the heart on the body surface and the sequence of propagation of the excitation wave along the atrial epicardium in rats with experimentally induced pulmonary hypertension caused by a single injection of monocrotaline (60 mg / kg, four weeks after drug administration).

Results. Pulmonary hypertension causes the appearance of an additional focus of initial excitation in the area of the pulmonary vein lacunae, which leads to an increase in the heterogeneity of the propagation of the excitation wave along the atrial epicardium. The appearance of the additional excitation focus in the mouths of the pulmonary veins in the left atrium changes the picture of the sequence of depolarization of the atrial epicardium. The heterogeneity of the propagation of the excitation wave along the atrial epicardium is reflected in a different arrangement of zones of positive and negative cardioelectric potentials on the body surface before and during the P-wave in comparison with the initial state.

Conclusion. Induced pulmonary hypertension contributes to the appearance of an additional focus of initial excitation in the area of the sleeves of the pulmonary veins of the left atrium in rats. This leads to an increase in the heterogeneity of the propagation of the excitation wave along the atrial epicardium. This is also reflected in the change in the arrangement of the zones of positive and negative cardioelectric potentials on the body surface before and during the P-wave in comparison with the initial state.

Miasto jako przedmiot pedagogicznej refleksji Sarajewskie reminiscencje
Authors: Pilarska Justyna
Published: June 2020

Niniejszy tekst poświęcony jest teoretycznym refleksjom budującym narrację wokół miejsca jako kategorii znaczącej pedagogicznie. Współczesna mobilność oraz charakter przemian społecznych XXI wieku nadaje kategorii miejsca znaczący status we współtworzeniu edukacyjnych odniesień w procesie wychowania i socjalizacji. Jest to szczególnie istotne w przypadku społeczeństw zróżnicowanych kulturowo, do których należą Bośnia i Hercegowina. W tekście autorka, bazując na swych długoletnich doświadczeniach badawczych z Sarajewa, porusza zagadnienia znaczenia miasta i miejsc dla kreowania lokalnych tożsamości, jednakowoż przybliżając niektóre z podejść i metod empirycznych eksploracji skupionych na kategorii miejsca i relacji człowiek–miejsce.
Badacz jako Obcy w terenie Proces wżywania się w środowisko lokalne na podstawie dzienników badań terenowych
Authors: Odyniec Katarzyna
Published: June 2020

Artykuł przedstawia wybrane wyzwania, problemy i wątpliwości wiążące się z prowadzeniem badań terenowych w pedagogice społecznej. Przedstawione są one z punktu widzenia badacza wchodzącego do nowego środowiska. Proces wżywania się w środowisko jest elementem niezbędnym a jednocześnie trudnym i długotrwałym wymagającym od badacza rzetelnych przygotowań teoretycznych i empirycznych. Jednakże bez niego niemożliwe jest zrozumienie kontekstu, „klimatu” lokalnych wartości i znaczeń budujących badaną „małą ojczyznę”. Poruszane zagadnienia dotyczą przyjmowania perspektywy emicznej lub etycznej, strategii przekraczania granic poznawczych oraz emocjonalnej strony prowadzenia badań w terenie. Większą część tekstu to wybór z osobistych dzienników autora, prowadzonych podczas badań terenowych w latach 2017–2019 na terenie powiatu bialskiego (województwo lubelskie).

Published: June 2020

Today’s system of accounting does not contain sufficient volumes of information about environmental incomes and losses of organizations, therefore, it is nearly impossible to evaluate precisely the efficiency of environmental actions taken and environmental protection systems being implemented in order to maintain and/or increase the environmental balance. One of the key elements in the mechanism increasing the quality of economic performance is the system of environmental accounting.

This study explains both theory and methodology of environmental accounting and also determines its role and place within the system of existing types of accounting and reporting in accordance with the IFRS requirements and also Kyoto Protocol. The presented here organizational economic mechanism of environmental accounting allows implementing the latter at concrete enterprises so that to promote and support more efficient managerial decision-making.
