Authors: Chatti Walid , Khoj Haitham
Published: December 2020

This study aims to examine the causal linkages relating service exports to internet penetration for 116 countries over the period 2000-2017. Taking into account a wide panel of countries, we apply 2-Step GMM methodology for dynamic panel data models. The results show a bi-directional causality relating service exports to internet adoption for developed countries. For the global panel and developing countries, we find those same results attest a positive relationship between the internet adoption and service exports, but in the opposite way; the impact is very low and not significant. Regarding developing countries, despite the fact that internet positively affects service exports, it is considered less efficient than in developed countries.
The Impact of Asnaf Entrepreneur’s Intention Towards Decision and the Movement of Zakat Collection
Authors: Din Noormariana Mohd , Muhammad Mohd Zulkifli , Ismail Mohammad , Said Nadzirah Mohd
Published: December 2020

Decision is an issue that needs to be explored in detail due to its relationship to an individual’s psychology. In the context of zakat that also acts as microfinancing (non-refundable fund), decision plays an important role in terms of collection and distribution. However, previous literature about zakat has not clarified this phenomenon especially in the context of Asnaf entrepreneurs. Asnaf entrepreneurs represent micro entrepreneurs who depend on zakat funds. Then, by benefiting the funds and getting support from the zakat institutions, Asnaf entrepreneurs become less dependent on the support and become zakat payers. Therefore, grounded by Theory of Planned Behaviour (TPB) framework, the purpose of this paper is to investigate the impact of Asnaf Intention’s towards decision as the zakat payers. A total of 274 Asnaf entrepreneurs from Kelantan and Selangor had participated in this study. Data were collected through self-administered survey questionnaires. The main statistical technique used in this study is Structural Equation Modelling (SEM) by using Analysis of Moment Structure (AMOS) version 23. The study has shown that subjective norms are found to be most dominant predictor towards decision closely followed by attitude, and perceived behavioural control. The above findings have added several implications towards theory, both practical and managerial. In general, the findings of the study are consistent with the theory of planned behaviour. Moreover, Asnaf entrepreneur’s intention gives the better impact towards decision and zakat collection.
Prediction of CPI in Saudi Arabia: Holt’s Linear Trend Approach
Authors: Ali Anis , Mahgoub Ayman
Published: December 2020

The Consumer Price Index (CPI) indicates and measures price level changes in an economy based on total purchased goods and services. CPI is calculated by dividing the cost of the market basket in a given year by the cost of the market basket in a Base Year and multiplied by 100. CPI is subject to the Classification of Individual Consumption by Purpose (COICOP) in Saudi Arabia. Home expenditure items, such as housing, water, electricity, gas, and other fuels, food, and beverages are considered high while weight, health, education, recreation, and culture are given low weight in the COICOP in Saudi Arabia. Holt’s linear model based on three equations and popularly known as double exponential smoothing or linear exponential model and the most commonly used method in forecasting data based on internal trends. Holt’s linear model is composed of three equations relating to smoothing, trend, and forecast. In this paper, the CPI data were taken monthly from the General Authority for Statistics, Saudi Arabia for the period from May 2019 to July 2020 with 15 realizations. The CPI for Saudi Arabia is predicted for the next twelve months and as observed from the trend of CPI, the prices of total purchased goods will increase in the next eleven months.
A Tale of Two Shitties
Authors: Robertson William
Published: December 2020

Based on 12 months of ethnographic data collection in an anal cancer prevention clinic, this article uses the extreme examples of patients involuntarily defecating through the anoscope during the procedure to highlight the relationship between the extreme and the everyday. Despite the rarity of this occurrence, I argue that these extreme examples shed light on the ways the daily clinical routines are embodied as an expert habitus. High Resolution Anoscopy procedures are specialized, highly routinized practices that are performed hundreds of times per month at the clinic. These routines result in the development of a clinical habitus that guides physicians in deploying techniques to efficiently conduct the invasive examination. Exemplary examples of ordinary procedures certainly help explain how this expert habitus is enacted through routine clinical practices; however, this expertise becomes especially observable in moments when habituated practices are disrupted, forcing clinicians to react and respond in unscripted ways. I discuss the only two instances of patients defecating through the anoscope that occurred while conducting my research, each with a different clinician. These extreme examples provide rich opportunities to analyze how clinicians with similar procedural habits navigate extraordinary situations in expert and professional but idiosyncratic ways. Whereas exemplary examples of everyday routinized procedures can show the process of developing an expert clinical habitus, these extreme examples more clearly demonstrate how this habitus enacts expertise and professionalism by highlighting the clinicians’ abilities to deftly navigate the technical and sociocultural aspects of such extraordinary disruptions.

Published: December 2020

Background: Oral mucositis is a common debilitating complication of cancer chemotherapy and radiotherapy that can reduce the quality of patient’s lives. Hence, treating this condition plays an important role in increasing the patient’s tolerance. Objectives: Doxepin mucoadhesive gel is useful for treating oral mucosa inflammation caused by long-term effects of chemotherapy, which has low adverse effects. Methods: Doxepin gel’s formulation was prepared with various concentrations of poloxamer 407 and hydroxypropyl methylcellulose in deionized water. The prepared gels were evaluated for pH, appearance, viscosity, spreadability, stability, and drug release. Results: After providing gels containing doxepin, formulations 1, 2, 8, and 9 had low quality and, thus, were removed from the study. Based on qualitative evaluations, formulations 3 and 4 did not meet the criteria for mucoadhesive gel and were removed from the study. The best formulation contained 17% w/w poloxamer 407, 10% w/w hydroxypropyl methylcellulose, and 5% w/w doxepin. Conclusions: Suitable physicochemical properties of prepared doxepin mucoadhesive gel enable it to well cover inflamed and damaged oral mucosa. On the other hand, doxepin’s slow release from formulation (8 hours) can increase therapeutic effects and reduce side effects, which can heal and soothe inflammations of the oral mucosa and be useful in cancer patient’s treatment.

Authors: Jolović Nevena
Published: December 2020

Since March 2020, the global labor market has been exposed to exceptional shocks due to the outbreak of a global pandemic - Coronavirus Disease 2019 (COVID-19). The COVID-19 crisis has threatened subjects and shaken relations in labor markets around the world, and employment levels in the European Union (EU) and the United States of America (USA) have begun to oscillate significantly. The aim of the research is to review the trends observed in the labor markets of the EU and the USA during the first and second quarters of 2020, and to review the projections of eminent authors related to future trends in the mentioned markets. The analysis of the unemployment rate, as well as the policies and measures taken by the EU and USA governments in order to mitigate the consequences of the pandemic, were used in making the final assessment which of these systems suffered more damage, and which of them responded more adequately to crisis. The descriptive and comparative method, analysis and synthesis technique, as well as content analysis of available domestic and foreign literature, were used for research purposes. The result of the research is reflected in the observation that both the EU and the USA responded to the economic and social emergency, and through a number of initiatives supported employees and companies in their labor markets in a timely manner. Finally, the so-far analysis results show that after the first six months of 2020 the American labor market has been much more affected by the pandemic than the European labor market.

Published: December 2020

The future of the modern world faces the appearance of different ways of mobility. Huge strive in today's world have gained autonomous vehicles. The paper explains how autonomous vehicles function as well as their advantages and disadvantages. New developments in autonomous vehicles are being accomplished and introduced to the user's demands. Many car companies have developed their own driverless vehicles and detected the problems within them. The major flaw of autonomous vehicles is cyber security because hackers are still able to break into the car's software system and disrupt it. This is a major issue which is still being dealt with. Autonomous vehicles have modernized the mobility of people, which means that people no longer have to come to the vehicle but the vehicle comes to them and are able to share transportation and thus lowering the traffic congestion and cost. Smartphone applications have been developed facilitating the carsharing system. Users consider these cars comfortable and stylish but expect high level of security. Autonomous vehicles enable the elderly, the disabled and physically limited people move much easier. Furthermore, autonomous vehicles reduce pollution and are environmentally friendly. It is anticipated that autonomous vehicles will take over the roads and are the future of transportation. They offer comfort, safety and good driving conditions. Hereafter, this paper represents important characteristics and features of autonomous cars.
Reducing labor intensity when computing optimal technical characteristics of aerial ropeways
Authors: Lagerev Alexander , Lagerev Igor
Published: December 2020

The article develops a procedure for optimizing the technical characteristics of ropeways - the step and the height of intermediate towers, and carrying ropes tension force. The optimization problem was based on the minimization of the tower structures cost. The reduction of computing labor intensity is based on the fact that the position of the minimum point of the objective function will be tied to one of the optimization restrictions. This allowed us to propose two ways to reduce the labor intensity of computing: a) reduction in the dimension of the optimization problem; b) replacement of the search for the minimum of the objective function with the solution of the nonlinear algebraic equation. The article shows that the proposed algorithm has increased computational efficiency. The algorithm allows us to obtain the same optimal values of technical characteristics of ropeways as in the solution of the previously developed optimization task but using simpler mathematical methods.
FAT-based adaptive backstepping control of an electromechanical system with an unknown input coefficient
Authors: Al-Shuka Hayder
Published: December 2020

This paper is focused on orthogonal function approximation technique FAT-based adaptive backstepping control of a geared DC motor coupled with a rotational mechanical component. It is assumed that all parameters of the actuator are unknown including the torque-current constant (i.e., unknown input coefficient) and hence a control system with three motor control modes is proposed: 1) motor torque control mode, 2) motor current control mode, and 3) motor voltage control mode. The proposed control algorithm is a powerful tool to control a dynamic system with an unknown input coefficient. Each uncertain parameter/term is represented by a linear combination of weighting and orthogonal basis function vectors. Chebyshev polynomial is used as a strong approximator for estimation of uncertainty. The designed control law includes three terms: a feedforward term, a feedback term and a robust term for compensation of modeling error. Lyapunov stability is used to prove the validity of the proposed controller and to derive the update laws for the weighting vectors of orthogonal Chebyshev approximators. A case study of a geared DC motor in connection with a rotating output load is simulated to prove the effectiveness of the proposed controller structure.

Published: December 2020

Metal hydrides are broadly investigated, for more than three decades, towards its application for cooling and heating applications. As a continuation of those works, in the present study, authors have investigated the performance of a multi-stage sorption heat pump for multiple cooling and heating outputs. The metal hydrides selected for the present study are Ti0.98Zr0.02V0.43Fe0.09Cr0.05Mn1.5, MmNi4.7Al0.3, LaNi4.8Al0.2 and Zr0.9Ti0.1 Cr0.9Fe1.1, with the operating temperature range as 20°C for cooling output, 45°C for heating output and 140°C for heat supply. The system produces three cooling and four heating outputs with only one heat input. The performance of the system is investigated, via finite volume approach, in terms of hydrogen interaction within the coupled beds, bed temperature variations and heat interactions during hydrogen transfer processes. The minimum temperature observed during the cooling process is 0.5°C, whereas the maximum temperature observed during the heating process is 60°C, which shows that the obtained temperature is capable of space air-conditioning. On the other hand, the maximum cooling and heating outputs, at a particular instant of time, are estimated at 361 W and 402 W, respectively with a heat supply of 23 W.

Authors: Purnomo P , Setyarini Putu , Anggono Agus
Published: December 2020

The aim of this work is to investigate the fracture toughness and deformation of silk fiber (SF)-reinforced zeolite (Z)/high density polyathylene (HDPE) composites. The chopped SFs are arranged in the thickness middle of the dry mixture of Z/HDPE powder that has been prepared in a mold. Composites were produced by the compression molding to produce double-edge notch tensile (DENT). The fracture toughness characterization was carried out based on essential work of fracture method. The results show that the presence of SF increased the essential fracture work even though the non-essential fracture work for Z/HDPE was higher than S-Z/HDPE. The evolution of plastic zone growth coincides with the growth of the fracture process zone (FPZ) whose height has no effect on energy consumption.
Unsteady nonlinear panel method with mixed boundary conditions
Authors: Hamid Ali
Published: December 2020

A new panel method had been developed to account for unsteady nonlinear subsonic flow. Two boundary conditions were used to solve the potential flow about complex configurations of airplanes. Dirichlet boundary condition and Neumann formulation are frequently applied to the configurations that have thick and thin surfaces respectively. Mixed boundary conditions were used in the present work to simulate the connection between thick fuselage and thin wing surfaces. The matrix of linear equations was solved every time step in a marching technique with Kelvin's theorem for the unsteady wake modeling. To make the method closer to the experimental data, a Nonlinear stripe theory which is based on a two-dimensional viscous-inviscid interaction method for each station along the wing spanwise direction and Prandtle-Glauert rule for compressibility effect were used to enhance the potential results of the method. The fast turnaround time and the ability to model arbitrary geometries is the goal of the present work. Different airplanes configurations were simulated (DLR-F4, light jet, cargo and four engine commercial airplanes). The results of pressure and forces coefficients were compared with the DLR-F4 airplane. The comparisons showed a satisfying agreement with the experimental data. The method is simple and fast as compared with other singularity methods, which may be dependent as a preliminary method to design aircrafts.

Published: December 2020

Greenhouses need energy to create a suitable climate for crop production in winter period. Renewable energy seems to be the appropriate and sustainable energy source to heat greenhouses. The aim of this work is to investigate the possibilities of improving the inner greenhouse climate using sensible heat storage material. A comparative study was conducted upon experimental tests carried out between control and heated greenhouse in a semi-arid region. A new design of greenhouse was proposed that consists of an economical rock-bed with the sensible heat technique for heating system in an integrated H-shape channel. The excess diurnal heat captured by the greenhouse is stored into the system and then restored for nocturnal heating. The results obtained indicate that this thermal storage system is efficient and ameliorates the greenhouse climate. The night temperature was improved by 3.2 °C and the relative humidity was reduced by 9.6%, compared to a standard greenhouse.

Proper planning of a warehouse layout and the product allocation in it, constitute major challenges for companies. In the paper, the new approach for the classification of the problem is presented. Authors used real picking data from the Warehouse Management System (WMS) from peak season from September to January. Artificial Neural Network (ANN) and automatic clustering by using Calinski-Harabasz criterion were used to develop a new classification approach. Based on the picking list the clients' orders were prepared and analyzed. These orders were used as input data to ANN and clustering. In this paper, three variants were analyzed: the reference representing the current state, variant with product relocation by using ANN, and the variant with relocation by using automatic clustering. In the research over 380000 picks for almost 1600 locations were used. In the paper, the architecture of the system module for solving the PAP problem is presented. Presented research proved that using multi-criterion clustering can increase the efficiency of the order picking process.

Authors: Lorenc Augustyn , Burinskiene Aurelija
Published: December 2020

The primary purpose of the research is the improvement of the orders picking process without additional investments for the software, employees, tool and inventories. For problem-solving, the data about picking is exported and preprocessed from WMS. The BigData analysis and product clustering in Tableau software is delivered using the data, where the Product Allocation Problem (PAP) is solved. Picking time for reference scenario and new analysed one is calculated and compared. The presented research proves that standard data collected by WMS could be used for solving PAP for the reduction of total picking time. The method delivered by authors could be in a typical warehouse, where forklifts and employees do the order picking process. The plan after an upgrade could be used for automatic picking, and implemented WMS. For BigData analysis, Tableau is connected to WMS database. Such solution could be used for everyday analysis and planning the allocation of products. The presented method is easy to use; there is no need to invest in expensive software and automation of the picking process to achieve the high performance of the orders picking process. However, its application allows the increase of efficiency rates. Storekeepers can select more products at the same time. The presented research is original because of using simple methods and analysis of specific data, which until now are only used to calculate employee performance indicators.

Authors: Natarajan Narayanan , Rehman S. , Shiva Nandhini , Vasudevan M.
Published: December 2020

An accurate estimate of wind resource assessment is essential for the identification of potential site for wind farm development. The hourly average wind speed measured at 50 m above ground level over a period of 39 years (1980-2018) from 25 locations in Tamil Nadu, India have been used in this study. The annual and seasonal wind speed trends are analyzed using linear and Mann-Kendall statistical methods. The annual energy yield, and net capacity factor are obtained for the chosen wind turbine with 2 Mega Watt rated power. As per the linear trend analysis, Chennai and Kanchipuram possess a significantly decreasing trend, while Nagercoil, Thoothukudi, and Tirunelveli show an increasing trend. Mann-Kendall trend analysis shows that cities located in the southern peninsula and in the vicinity of the coastal regions have significant potential for wind energy development. Moreover, a majority of the cities show an increasing trend in the autumn season due to the influence of the retreating monsoons which is accompanied with heavy winds. The mean wind follows an oscillating pattern throughout the year at all the locations. Based on the net annual energy output, Nagercoil, Thoothukudi and Nagapattinam are found to be the most suitable locations for wind power deployment in Tamil Nadu, followed by Cuddalore, Kumbakonam, Thanjavur and Tirunelveli.

Published: December 2020

Taking into account the existing demand for chromium concentrates, the extraction of chromium from technogenic formations of sludge storages of the tailings of chromium ore beneficiation is an important practical task. The comprehensive utilization of beneficiation sludge will increase the profitability of production and solve the environmental problems of the region. The importance of solving the problem of involving in processing tailings is connected not only with the environment but also with the need to increase the production of chromium. Modern gravity enrichment technologies make it possible to efficiently produce chromium concentrates from large and medium fractions of chromite-containing ores, while finely divided sludge is practically not extracted due to the difficulty of separating complex minerals into concentrates and waste rock. This paper presents the results of studies on the gravity processing of tailings. The technology includes the enrichment of the fine fraction-0.2+0 mm of tailings of the dressing plant of chromite-containing ores by gravity methods using a KNELSON centrifugal separator. In technology, the efficiency of the operation of gravity enrichment is provided by the preliminary activation of the fine fraction in a solution of sodium bicarbonate (NaHCO3). With gravitational enrichment, the total chromite concentrate was obtained containing 51.3% Cr2O3. The output of concentrate was 41.7%. The extraction of Cr2O3 in the concentrate was 68.1%.

This paper will present the results of a study on dietary habits in adolescents. The high school or adolescent era is a time of great physical and psychological changes, which cause instability and oscillations in the mood and behavior of high school students. Results obtained by interviewing secondary school students about eating habits and results obtained using a standardized questionnaire for the risk of type 2 diabetes were analyzed using a reliable statistical tool IBM SPSS Statistical, which offers a range of reliable analyzes and statistical tests. Previous research has shown that for each person with type 2 diabetes, one person finds out who does not know it. Discovery of pre-diabetes, in new potential patients, is necessary at the earliest age, when a number of factors affect lifestyles, such as irregular nutrition and obesity, physical inactivity, stress, and others become important for the development of this disease. Detection of risk levels in potential patients is important for both the individual and public health, and everyday clinical practice. After determining the degree of risk for a particular sample, a set of measures for a particular adolescent population will be recommended, so that the disease does not occur, or its onset will move for a later period of life.

Authors: Mihajlović Danilo
Published: December 2020

Exegesis of Old Testament by Egyptian ascetics is yet to be discovered. Interpretational patterns of biblical texts in Egyptian Lives of Fathers (Paterikon) are specific because they are reflecting nature of Egyptian fathers' ascetical praxis in Early Church. Representative examples of this kind of exegesis could be find in quotations of Old Testament Wisdom literature in above mentioned Egyptian Lives of Fathers. Special attention should be paid to literal readings of this kind of Old Testament literature, as well as on making analogies.

Metropolitan Theophan Fan Noli was a leader of the Church both in America and his native Albania. He was a pioneer in calling for a united Orthodox Church in America and in the use of English in services. Noli began his life of service in the Church in the United States organizing Albanian parishes. With the Balkan Wars and the independence of Albania, Fan Noli devoted more of his time to the cause of Albania. He was Prime Minister of Albania in 1924. After a change in political climate, Bishop Theophan was forced to leave Albania. He was able to return to the United States in 1932. Upon arriving he retired from politics and resumed his duties as bishop of the Albanian Orthodox Church in America. Bishop Noli considered his Albanian Church as a daughter of the Russian Orthodox Church in America and looked to it for the creation of a single Orthodox Church in America. He continued to lead his flock and to advocate Orthodox unity until his death in 1965.
Council and primacy in the Church
Authors: Stojanović Marina
Published: December 2020

The unity of the Church, as has long been established, is expressed through its synodality. This notion, present and explained throughout the history of Christianity, seems to have lived more through councils and liturgical communion than has become a transparent, defined and quite clear theological notion. Whenever, in the spirit of Western rationalism, an attempt was made to explain the concepts of council and synodality, there was a contradiction between the metaphysical concepts formed in antiquity, one and many. Expressed in theological terminology, it is about the relationship between the council and the primacy in the Church, which should be preserved so that it does not fall into crises on the local and universal level as we are witnessing today. The council of the Church, as an expression of the fullness and harmony of all its members (limbs), cannot be treated as an institution of hierarchy that implies subordination or as a collective of socially organized individuals. The present paper briefly discusses the issue of the synodality and the primacy in the light of current problems in Orthodoxy, and emphasizes the patristic and traditional approach to this topic, built on the interpretation of the existence of the Trinity.

The aim of this study was the determination of the antioxidant and antihyperglyce-mic effect of wild grown rosehip and pomegranate fruit extracts, and the determination of the polyphenolic content (total phenols, flavonoids, flavonols, flavan-3-ols and total and monomeric anthocyanins). The antioxidant activity of rosehip fruit in view of stable DPPH and ABTS radicals was higher comparing to pomegranate fruit, while according to the OH radical these two samples showed a similar effect (94.17 and 92.03 mg/mL). A dry rosehip fruit extract was found to have a 1.6 times more pronounced antihyperglycemic activity (1.42 mg/mL) compared to the dried pomegranate fruit extract (2.26 mg/mL). The content of total phenols of rosehip fruit was 8.75 mg GAE/g FPM and 22.01 mg GAE/g DPM , higher than the content of total phenols of pomegranate fruit (3.44 mg GAE/g FPM and 15.43 mg GAE/g DPM). The content of total phenols in rosehip and pomegranate fruits was higher than the content of total flavonoids, flavonols and flavan-3-ol and total and monomeric anthocyanins, which indicates that these components had the greatest impact on bioactivity of wiled grown fruits. Due to their bioactivity, the fruits of wild grown rosehip and pomegranate can be considered as potential functional food and food suitable for diabetics.
Disadvantages of herbaceous oil-bearing plants as feedstock in the biodiesel production
Authors: Tasić Marija
Published: December 2020

The cultivation of non-edible oil-bearing plants as feedstocks for the biodiesel production can aggressively take advantage of natural environments. Herbaceous non-edible oil-bearing plants have been significantly favored as an ideal feedstock for biodiesel fuel, though little is known about its industrial feasibility and environmental impact. The items with the greatest sensitivity in capital and ecology are land acquisition, plant life cycle, mechanical harvesting, fertilizer, control of weed, pests and diseases, seed yield and oil content. This study aims at analyzing the disadvantages of herbaceous non-edible oil-bearing plants and suggests impeding their industrial cultivation for the biodiesel production. The source of information for the proper selection of non-edible oil-bearing plants suitable as biodiesel feed-stocks has been the recent relevant literature. Herbaceous non-edible oil-bearing plants have a low phytoremediation potential and oil yield, but high weed potential. They occupy a large arable area while demand harder cultivation conditions and mechanical harvesting. Non-edible oils from woody plants are promising biodiesel feedstock. However, the weed potential of woody oil-bearing plants must also be considered to prevent their invasiveness.
Student centered learning: The paradigm of modern higher education
Authors: Ćirić Marina , Petrović Jelena , Jovanović Dragana
Published: December 2020

Student centered learning implies the pedagogical approach based on constructivism and theories related to it, and it is characterized by the methods used to make a student actively contribute the learning process. It is recognized in the mindset and culture of the faculty, and focused on the needs and opinions of students. This paper presents the main elements of this approach in the context of higher education system. It starts with the perspective that placing the student at the center, the "heart" of the educational process, is a response to numerous social challenges and the reform process. The first part of the paper highlights a dichotomy resulting from the need to reconceptualize the traditional educational system in order to respond the needs of the knowledge society. It further points out the particularities and the differences between the teaching paradigm and the learning paradigm and elaborates the (im)possibility of combining them. The second part of the paper is dedicated to the analysis of the possibilities for implementing student-centered approach in higher education institutions and making it an integrative part of their climate and learning culture.
