The Effect of Mg, Fe(II), and Al Doping on CH4: Adsorption and Diffusion on the Surface of Na-Kaolinite (001) by Molecular Simulations
Authors: Wang Kai , Zhang Bin , Kang Tianhe
Published: February 2020

Because kaolinite includes a large range of defect elements, the effects of Mg, Fe(II), and Al doping on the CH4 adsorption and diffusion on the surface of Na-kaolinite (001) were investigated by molecular simulations. The simulation results illustrate that ion doping can significantly reduce the amount of CH4 adsorbed by kaolinite, but the type of doped ions has little effect on the amount of adsorption. The specific surface area of kaolinite and the interaction energy between CH4 and the kaolinite’s surface are two key factors that can determine CH4 adsorption capacity. The first peak value of the radial distribution functions (RDFs) between CH4 and the pure kaolinite is larger than that between Mg-, Fe(II)-, and Al-doped kaolinite, which indicates that ion doping can reduce the strength of the interactions between CH4 and the kaolinite’s surface. Besides hydrogen and oxygen atoms, interlayer sodium ions are also strong adsorption sites for CH4 and lead to a weakened interaction between CH4 and the kaolinite’s surface, as well as a decrease in CH4 adsorption. Contrary to the adsorption results, ion doping facilitates the diffusion of CH4, which is beneficial for actual shale gas extraction.
Computational Studies of Molecular Materials for Unconventional Energy Conversion: The Challenge of Light Emission by Thermally Activated Delayed Fluorescence
Authors: Sanz-Rodrigo Javier , Olivier Yoann , Sancho-García Juan-Carlos
Published: February 2020

In this paper we describe the mechanism of light emission through thermally activated delayed fluorescence (TADF)—a process able to ideally achieve 100% quantum efficiencies upon fully harvesting the energy of triplet excitons, and thus minimizing the energy loss of common (i.e., fluorescence and phosphorescence) luminescence processes. If successful, this technology could be exploited for the manufacture of more efficient organic light-emitting diodes (OLEDs) made of only light elements for multiple daily applications, thus contributing to the rise of a sustainable electronic industry and energy savings worldwide. Computational and theoretical studies have fostered the design of these all-organic molecular emitters by disclosing helpful structure–property relationships and/or analyzing the physical origin of this mechanism. However, as the field advances further, some limitations have also appeared, particularly affecting TD-DFT calculations, which have prompted the use of a variety of methods at the molecular scale in recent years. Herein we try to provide a guide for beginners, after summarizing the current state-of-the-art of the most employed theoretical methods focusing on the singlet–triplet energy difference, with the additional aim of motivating complementary studies revealing the stronger and weaker aspects of computational modelling for this cutting-edge technology.

Published: February 2020

The mixture containing alloy and oxide with iron-based phases has shown interesting properties compared to the isolated species and the synergy between the phases has shown positive effect on dye adsorption. This paper describes the synthesis of Fe2SiO4-Fe7Co3-based nanocomposite dispersed in Santa Barbara Amorphous (SBA)-15 and its application in dye adsorption followed by magnetic separation. Thus, it was studied the variation of reduction temperature and amount of hydrogen used in synthesis and the effect of these parameters on the physicochemical properties of the iron and cobalt based oxide/alloy mixture, as well as the methylene blue adsorption capacity. The XRD and Mössbauer results, along with the temperature-programmed reduction (TPR) profiles, confirmed the formation of Fe2SiO4-Fe7Co3-based nanocomposites. Low-angle XRD, N2 isotherms, and TEM images show the formation of the SBA-15 based mesoporous support with a high surface area (640 m2/g). Adsorption tests confirmed that the material reduced at 700 °C using 2% of H2 presented the highest adsorption capacity (49 mg/g). The nanocomposites can be easily separated from the dispersion by applying an external magnetic field. The interaction between the dye and the nanocomposite occurs mainly by π-π interactions and the mixture of the Fe2SiO4 and Fe7Co3 leads to a synergistic effect, which favor the adsorption.

A broadband graphene-on-Si3N4-membrane photodetector for the visible-IR spectral range is realised by simple lithography and deposition techniques. Photo-current is produced upon illumination due to presence of the build-in potential between dissimilar metal electrodes on graphene as a result of charge transfer. The sensitivity of the photo-detector is ∼1.1 μA/W when irradiated with 515 and 1030 nm wavelengths; a smaller separation between the metal contacts favors gradient formation of the built-in electric field and increases the efficiency of charge separation. This optically-thin graphene-on-membrane photodetector and its interdigitated counterpart has the potential to be used within 3D optical elements, such as photonic crystals, sensors, and wearable electronics applications where there is a need to minimise optical losses introduced by the detector.
Crosstalk between RNA Metabolism and Cellular Stress Responses during Zika Virus Replication
Authors: Oyarzún-Arrau Aarón , Alonso-Palomares Luis , Valiente-Echeverría Fernando , Osorio Fabiola , Soto-Rifo Ricardo
Published: February 2020

Zika virus (ZIKV) is a mosquito-borne virus associated with neurological disorders such as Guillain-Barré syndrome and microcephaly. In humans, ZIKV is able to replicate in cell types from different tissues including placental cells, neurons, and microglia. This intricate virus-cell interaction is accompanied by virally induced changes in the infected cell aimed to promote viral replication as well as cellular responses aimed to counteract or tolerate the virus. Early in the infection, the 11-kb positive-sense RNA genome recruit ribosomes in the cytoplasm and the complex is translocated to the endoplasmic reticulum (ER) for viral protein synthesis. In this process, ZIKV replication is known to induce cellular stress, which triggers both the expression of innate immune genes and the phosphorylation of eukaryotic translation initiation factor 2 (eIF2α), shutting-off host protein synthesis. Remodeling of the ER during ZIKV replication also triggers the unfolded protein response (UPR), which induces changes in the cellular transcriptional landscapes aimed to tolerate infection or trigger apoptosis. Alternatively, ZIKV replication induces changes in the adenosine methylation patterns of specific host mRNAs, which have different consequences in viral replication and cellular fate. In addition, the ZIKV RNA genome undergoes adenosine methylation by the host machinery, which results in the inhibition of viral replication. However, despite these relevant findings, the full scope of these processes to the outcome of infection remains poorly elucidated. This review summarizes relevant aspects of the complex crosstalk between RNA metabolism and cellular stress responses against ZIKV and discusses their possible impact on viral pathogenesis.
Fluid–Solid Coupling Model and Simulation of Gas-Bearing Coal for Energy Security and Sustainability
Authors: Hu Shixiong , Liu Xiao , Li Xianzhong
Published: February 2020

The optimum design of gas drainage boreholes is crucial for energy security and sustainability in coal mining. Therefore, the construction of fluid–solid coupling models and numerical simulation analyses are key problems for gas drainage boreholes. This work is based on the basic theory of fluid–solid coupling, the correlation definition between coal porosity and permeability, and previous studies on the influence of adsorption expansion, change in pore free gas pressure, and the Klinkenberg effect on gas flow in coal. A mathematical model of the dynamic evolution of coal permeability and porosity is derived. A fluid–solid coupling model of gas-bearing coal and the related partial differential equation for gas migration in coal are established. Combined with an example of the measurement of the drilling radius of the bedding layer in a coal mine, a coupled numerical solution under negative pressure extraction conditions is derived by using COMSOL Multiphysics simulation software. Numerical simulation results show that the solution can effectively guide gas extraction and discharge during mining. This study provides theoretical and methodological guidance for energy security and coal mining sustainability.
Región v štruktúre územnej samosprávy
Authors: Hoghová Kristína
Published: February 2020

The concept of regional identity encompasses a number of fields, elements and subjects that create it. There are many definitions in the current scientific literature characterizing this topic. We encounter a large number of definitions, mainly in foreign studies. Under the conditions of the Slovak Republic, this field is much less explored. On the one hand, the individual self-governing regional units strive to maintain their uniqueness and preserve their historical and cultural values, economic or social status. On the other hand, they implement regional identity in their Social and Economic Development Programs minimally. It is the citizens themselves, visitors, investors, public and private subjects, central government and many other factors that shape the region's identity in Slovakia. The Regional Identity Index (IRI) is an effective tool for measuring regional identity in each self-governing region. Thus, it determines the overall level achieved in a certain period and can lead to useful information about the functioning and future direction of the territory. However, the calculation of IRI in the conditions of Slovak self-governing regions is significantly absent. Based on the research problem, the main aim of this paper is to propose an IRI for self-governing regions in the conditions of the Slovak Republic. The calculation will be formulated through quantitative data and factors, predefined and implemented schemes in practice. Príspevok poukazuje na skutočnosť, že systematický každoročný výpočet indikátorov môže byť nie len pre samosprávne kraje, ale aj miestne samosprávy (obce a mestá) smerodajným pri vypracovaní strategických dokumentov v oblasti územného rozvoja, prijímaním miestnych politík či budovaním marketingovej stratégie územia, čím by sa zvyšovala konkurencieschopnosť a regionálny rozvoj vo všetkých úrovniach územnej samosprávy. The paper points out that the systematic annual calculation of indicators can be decisive not only for the self-governing units, but also for local self-governments (municipalities) in the preparation of strategic documents in the fields of spatial development, adopting local policies or building the marketing strategy of the territory. This would increase competitiveness and regional development at all levels of territorial self-government.

Authors: Molčan Martin
Published: February 2020

The aim of our study was to analyse the communication of the mayor of the village with its citizens in the selected village of Jarovnice. The case study method was used. Communication channels of the municipality included: municipal radio, posters, leaflets and personal, written or telephone communication. Communication between the municipality and the citizen as a client was at a good level and without any major failings. However, the communication of municipality towards its citizen was mostly unidirectional. The most popular form of communication in Jarovnice was personal because of its positive feedback. However, the municipality had insufficient information sources which resulted in lack of information of citizens about the intentions and plans of the municipality. In order to improve communication channels towards the citizens, the municipality communication strategy should be carried out and implemented.
Role of Tax Havens in Tax Avoidance by Multinationals with Special Regard to Ireland
Authors: Wágner Tamás Zoltán
Published: February 2020

Nowadays, many multinationals use tax avoidance strategies in order to minimise their tax liability. They often cooperate with governments providing them preferential treatment. These low-tax jurisdictions called tax havens pose a threat for world economy because they result in huge budgetary loss for countries. Even the European Union has its own tax havens which contribute to the loss of 250 billion euros annually. It is more than 2% of the Union’s GNP. Despite the apparent negative evidences, several member states’ tax system still contains favourable provisions for multinationals. Although, almost everybody would mention the Benelux states first, but many multinationals utilize the loopholes of the Irish tax system. In this regard, it is enough to refer to the Apple case where the European Commission ordered the recuperation of 13 billion euros from the company due to illegal state aid. Hence, we conducted a research based on academic literature and case-law. After a short introduction and dealing with the European Commission’s response to tax avoidance, we analyse the Irish tax system. The main goal was to demonstrate that Ireland – despite the denial of the respective authorities – was a tax haven. Our study proves that multinationals could use almost freely several tax optimisation strategies (e.g. Double Irish and Dutch Sandwich) up to now. Due to strong criticism and scandals the government had to amend the former tax regime, but it does not mean that preferential treatment is abolished. Ireland still should be considered a tax haven.

Low-Error Reconfigurable Fixed-Width Multiplier for Image Processing Applications
Authors: S Sivanantham , JEYAKUMAR Jean Jenifer Nesam
Published: February 2020

Compensating the error using additional circuitry is mandatory in a low-error fixed-width multiplier. Instead of compensating the error, reconfiguring n-bit fixed-width multiplier to n/2-bit error-free full-width multiplier using decomposed multiplication is proposed in this paper. The decomposed block multiplication using an area-efficient New Bit Pair Recoding (NBPR) algorithm in fixed-width mode shows a relatively lesser truncation error than existing truncated multipliers. Reconfigurable 16x16   NBPR multiplier in three different modes (8x8, 16x8,16x16) with a fixed 16-bit product is verified on the TSMC 65nm CMOS standard cell library. The experimental results show that the NBPR multiplier consumes a lesser area than standard Booth multipliers. Evaluating the proposed multiplier in imaging shows improved PSNR with minimal error compared to other fixed-width multipliers
Integrating Renewable Energy Systems into Urban Furniture for Recreational Spaces: A Design Proposal for Konya Adalet Park
Authors: TERECİ Ayşegül , ATMACA Merve
Published: February 2020

Recreational areas are designed to promote physical activities as well as provide opportunities for relaxation. Recreational open spaces improve the long-term environmental and social sustainability of cities. These areas offer natural beauty in and around cities while sustaining the environmental equilibrium of city life. They also serve as a socialization hub for people to make contact with each other. They can also be promoting areas for sustainability. Introducing the use of technology in public areas will promote its use in daily life also. One area of technological advances that needs to be promoted for establishing sustainable communities is the integration of renewable energy resources for our daily needs. This study focuses on difficulties and strategies for the integration of renewable energy in recreational areas and evaluates a recreational open space; i.e. Adalet Park in Konya in terms of possible applications of renewable energy sources. Since solar energy potential is high in Konya PV integration is the best option for the area. On the other hand, wind power is not sufficient for producing energy with wind turbines, hence, wind belts and small scale wind mills can be integrated into the park furniture. To this end, the design of various urban furniture with integrated renewable energy systems was prepared for the Karatay Adalet Park in Konya; and the amount of energy that can thus be produced was determined. According to calculations using wind and solar data and a software, it is possible to produce 50 MWh/a of electrical energy with these installations.

Authors: ERDEM Osman Emin , KESEN Saadettin Erhan
Published: February 2020

Technological advancements coupled with growing world population require the increasing need of energy. Natural gas is one of the most important usable energy resources. Turkey is with high external dependency on energy as it has its own limited natural and underground energy resources. Thus, in order to effectively and productively use of natural gas purchased from foreign countries and to make reliable and robust energy policies for the years ahead, it is crucial to make a reasonable and plausible prediction for natural gas consumption of Turkey. In this paper, we estimate the natural gas consumption using machine learning techniques on the basis of real monthly data representing natural gas consumption of Turkey between the years 2010 and 2018. The performances of machine learning techniques involving Artificial Neural Networks, Random Forest Tree, Regression, Time Series and Multiple Seasonality Time Series are compared in predicting the natural gas consumption of Turkey. Experimental results show that among the five techniques, artificial neural networks produce the best estimation, having the lowest mean square errors, followed by regression method. Time series shows the worst performance among all the techniques.

Published: February 2020

Consumption of fast food continuously can be detrimental to human health. An effective solution is to make innovative food that is able to meet the adequacy of nutrition, one of which is foodbar. The raw materials used in the manufacture of foodbar come from local commodities which are flourished, including sweet potatoes, green beans and Moringa and added porang to unite the three ingredients. Yellow sweet potato flour contains 77.7% carbohydrates with high digestibility (98%), while Moringa leaf flour contains 27.1 grams / 100 grams protein. Mung bean flour is used as a flavoring agent, while porang flour which is rich in glucomannan acts as a binder agent to produce foodbar products that are not easily destroyed. The treatment in this study used two factors, namely the composition of the composite flour and the composition of the addition of porang. Observations made include physical properties including water content, volume expansion, kamba density and texture of the foodbar. The best treatment on the foodbar was the combination treatment of 100 grams of yellow sweet potato flour (40 grams) green bean flour (60 grams) moringa leaf flour and (4%) porang (P3T1).
Global challenges to functioning of precious gemstones market
Authors: Khmara Maryna
Published: February 2020

The peculiarities of gemstone market functioning under the impact of globalization are examined. Modern condition of financial stabilization in world is defined and main features of gemstones are outlined. Negative impact of illegal market on socio-economic development of countries, namely on revenues to the country’s budget from the business, is revealed. The importance of the problem of transferring most of gemstones processing operations beyond the countries of production is emphasized. Poor public control over the circulation of precious stones is proven. The challenges are substantiated to be aggravating under the impact of globalization. The diamonds market, which has peculiar high demand, is analyzed: diamonds and derivatives account for 85% of global turnover. Application of managerial strategies for gemstones market to efficiently use resources is defined to be complicated by the fact that managerial strategies impact the high cost of product items and its variability; unique features; intangible qualities; complicated processing. More environmentally friendly production and social responsibility are confirmed to have impact on forming of demand on gemstones.

Authors: Pukhyr Svitlana
Published: February 2020

The paper is devoted to examining of theoretical and practical aspects of introduction of the Regions’ Inclusive Development Index. At current stage, the works of contemporary foreign and domestic scientists are focused on the research of inclusive development and inclusive growth, where they more or less outline substantial misbalances of global economy growth models – GDP volumes growth is accompanied by inharmonious distribution of income between the entities, leading to stratification of population and aggravating poverty – and suggest a new balanced model of economic growth of socio-economic systems with growing involvement of all residents in economic growth processes and fair distribution of their results. Growing gaps in regions’ development, low credibility of GRP per capita in terms of estimation of socio-economic development of territories, their competitive ability and problematic nature objectively cause the need to introduce a new aggregated index to systemically and complexly make constructive managerial decisions to overcome negative tendencies, to conduct efficient state regional policy and to provide state financial assistance. The author’s approach to introduction of «Region’s Inclusive Development Index» in Ukraine at the level of regions, which is an analogue to international «Inclusive Development Index», which should show the growth (fall) of residents’ welfare in the region more comprehensively and promote achievement of European standards of the quality of life, which correspond to the principles of inclusive growth. The results of calculations of suggested Region’s Inclusive Development Index and comparative analysis by the rate of GRP per capita in followup of socio-economic development of Ukrainian regions in 2016-2017 show the reasonability of introducing this criterion as far as it reveals the advantages and defects of each region’s socio-economic development.

Sustainable development of a modern enterprise requires constant development of employees’ intellectual potential. Therefore, the question of estimating the costs for the development of employees’ intellectual potential is urgent. It is also necessary to create a staff reserve of such qualifications that meet the requirements of technological progress. The availability of personnel reserve allows you to prepare candidates for the newly created positions, which arise during the upgrade of tangible and intangible assets. The purpose of the paper is to improve the approaches to the development of the intellectual potential of the employees of the enterprise by forming the personnel reserve of the corresponding qualification. The paper substantiates the need to form personnel reserve to secure the company’s sustainable development in conditions of continuous change of technologies. The authors suggest the updated scientific-applied approach to calculation of the necessary reserve of qualified staff, which is based on planned change of staff structure and advanced training based on current and planned rates of tangible and intangible assets, unlike the existing ones. The paper proves that the development of intellectual potential of the company’s staff requires certain expenses, which in their turn require accounting of their volumes. Methodical approach to assessment of the cost of intellectual potential of the company’s staff by calculation of the range of its components is presented. The obtained results are compared to the scale that contains criteria of the level of intellectual potential development depending on the volumes of investment in its development. The paper reveals that the cost of intellectual potential of the company’s staff expressed in the share of expenses in overall expenses should reach ten percent in order to secure for the company the sustainable development based on the tendencies and dominants of scientific and technical progress.

Published: February 2020

Background. There is not much evidence illustrating that statins could be responsible for memory loss or dementia, although increased exposure to statins has been reported to cause cognitive side effects. The present study investigated the effect of lovastatin in combination with rivastigmine on cognitive function as well as brain acetylcholinesterase (AChE) activity in normal mice.
Methods. The mice were categorized into four groups, and they were treated with normal saline, lovastatin, rivastigmine, and the combination of lovastatin and rivastigmine, respectively, by oral administration for 60 days. The treatment effect on cognitive functions was assessed by behavioral tests, namely, the passive avoidance test and spontaneous alternation test, as well as the measurement of brain AChE activity by Ellman’s method.
Results. In this study, a significant reduction (P < 0.01) of brain AChE activity and positive effects (P < 0.01) on cognitive functions was observed in mice treated with the combination of lovastatin and rivastigmine as compared to rivastigmine alone. However, no significant differences (P < 0.05) were observed on brain AChE activity as well as cognitive functions in mice treated with lovastatin when compared with those treated with normal saline.
Conclusion. This study suggested that lovastatin did not contribute to any improvements in cognitive functions and brain AChE activity, but it potentiated the effect of rivastigmine.

Primary Teachers’ Experiences in Preparing to Teach Irish: Views on Language Proficiency and Promoting the Language
Authors: Dunne Claire M.
Published: February 2020

The present study explores the process of becoming a primary level teacher of Irish, the official yet a minority language in Ireland. Since all primary level teachers must teach Irish, becoming a primary teacher in Ireland is bound up in complex ways with the process of becoming a teacher of a minority language and with personal attitudes to, and views on, the language itself. The current study analyses similarities and differences in views relating to teachers’ role in promoting the language, as well as issues in proficiency in the language, at the beginning and end of initial teacher education. Also examined is the extent to which above-average self-reported proficiency in Irish influences the experience of teaching Irish. Data is derived from responses to closed and supplementary open-ended questionnaire items administered to two different groups of pre-service teachers: at the beginning (n=75) and the end of initial teacher education (n=91), and is supplemented with data from interviews conducted with a subgroup of Group 2 (n=30). Data from this mixed methods study show that changes occur in the way teachers conceive of their future roles as teachers of Irish, and reveal the need for more support in aspects of their role such as nurturing positive attitudes to Irish amongst children and a desire for shared responsibility in promoting the language more generally.
