Published: October 2021

Investigation of the pegmatites of Keffi area was carried out in reflected light microscopy to determine the texture, elemental composition, and the semi-quantitative analysis of the ore minerals from the three groups of pegmatites identified in Keffi area: the non-mineralised, the intermediate and the mineralised pegmatites. Backscattered Electron (BSE) images and Wavelength Dispersive Spectrometry (WDS) were used. Petrographically the portion which is characterised by profuse albitisation, sericitisation and silicification is also associated with the development of cleavelandite, lepidolite, coloured tourmaline and high concentrations of cassiterite and columbite-tantalite (coltan).The order of crystallisation in the pegmatites is from microcline to quartz followed by (plagioclases) oligoclase to albite and by mica (from biotite to muscovite) then by accessory minerals such as black tourmaline, garnet, beryl and lastly oxides of Sn-Nb-Ta. Sphene, rutile, zircon, apatite, ilmenite, and magnetite appeared to be earliest minerals whilst garnet pyrite and chalcopyrite may be syn-metamorphic. Beryl and coloured tourmaline appear to be of hydrothermal phase.
Pedagogical and philosophical in postmodern philosophical discourse: the world as text
Authors: Tsybulko Olga , Martseniuk Larysa , Khvis Victoria , Salnikova Nataliya , Kudlai Viacheslav
Published: October 2021

The main purpose of the study is to determine the historical and pedagogical aspects of philosophical discourse. The difficulty in defining history as a scientific discipline is explained by the fact that this term is ambiguous and can be found in the scientific literature in three meanings. First of all, history is a certain entity, a substance, which unfolds its existence in time. A similar interpretation of history is close to speculative concepts of the philosophy of history. The ideas examined in the article indicate the presence in the modern scientific discourse of a polylogue, a dialogue of cultures, a plurality of conceptual views, both opposite and related, thereby substantiating the existence of a postmodern worldview paradigm. The result of the study was the characterization of historical and pedagogical aspects in philosophical discourse.

Performance Assessment of Real-Time Multiconstellation GNSS PPP Using a Low-Cost Dual-Frequency GNSS Module
Authors: Elmezayen Abdelsatar , El-Rabbany Ahmed
Published: October 2021

The release of low-cost dual-frequency (DF) global navigation satellite system (GNSS) modules provides an opportunity for low-cost precise positioning to support autonomous vehicle applications. The new GNSS modules support the US global positioning system (GPS) L1C/L2C or L5 civilian signals, the Russian GNSS Globalnaya Navigazionnaya Sputnikovaya Sistema (GLONASS) L1/L2, Europe’s GNSS Galileo E1/E5b, and Chinese GNSS BeiDou B1/B2 signals. The availability of the DF measurements allows for removal of the ionospheric delay, enhancing the obtained positioning accuracy. Unfortunately, however, the L2C signals are only transmitted by modernized GPS satellites. This means that fewer GPS DF measurements are available. This, in turn, might affect the accuracy and the convergence of the GPS-only precise point positioning (PPP) solution. Multi-constellation GNSS PPP has the potential to improve the positioning accuracy and solution convergence due to the high redundancy of GNSS measurements. This paper aims to assess the performance of real-time quad-constellation GNSS PPP using the low-cost u-blox Z9D-F9P module. The assessment is carried out for both open-sky and challenging environment scenarios. Static, simulated-kinematic, and actual field-kinematic trials have been carried out to evaluate real-time PPP performance. Pre-saved real-time precise orbit and clock products from the Centre National d’Etudes Spatiales are used to simulate the real-time scenario. It is shown that the quad-constellation GNSS PPP using the low-cost u-blox Z9D-F9P module achieves decimeter-level positioning accuracy in both the static and simulated-kinematic modes. In addition, the PPP solution convergence is improved compared to the dual- and triple-constellation GNSS PPP counterparts. For the actual kinematic trial, decimeter-level horizontal positioning accuracy is achieved through the GPS + GLONASS + Galileo PPP compared with submeter-level positioning accuracy for the GPS + GLONASS and GPS + Galileo PPP counterparts. Additionally, submeter-level vertical positioning accuracy is achieved through the GPS + GLONASS + Galileo PPP compared with meter-level positioning accuracy for GPS + GLONASS and GPS + Galileo PPP counterparts.
Geo-Electrical Method of Assessment of Coefficient of Permeability and Porosity of Soil of a Poultry Farmland

Published: October 2021

Leachate collected at the bottom of dead bird’s disposal pits may leak and migrate to pollute groundwater when soils and rocks present are porous. This study assessed the coefficient of permeability (K) and porosity (Ф) of soils and rocks in poultry farmland using 2 Dimensional (2D) electrical resistivity method and soil analysis. Geo-electrical data collection was achieved by using the dipole-dipole array. The field resistivity measurement was carried out along three traverse lines (three Profiles) of 100 m long which were oriented along with East-West directions. These measurements were taken in the order of increasing in offset distance interval of 5 m. The acquired apparent resistivity data were inverted using DIPPROWIN modeling software to perform 2D data inversion. Five soil samples from different locations at depths of 0 – 15 cm and 15 – 30 cm, on the poultry farmland, were collected, transported, and tested in the laboratory. K and Ф were determined using falling head and density methods respectively. The results obtained from the processed field resistivity data from the three profiles were presented as field data pseudo-sections, theoretical pseudo-section, and 2D resistivity structures. The 2D resistivity structure revealed three structures viz; highly conductive, slightly conductive, and resistive. The resistivity values of these structures ranged from 14.1-99.0 Ω m, 100-848 Ω m, and 1350-90330 Ω m respectively. The highly conductive structures were found in profiles 1 and 3 due to the downward migration of the contaminants from the dead bird disposal pit 1 and the feces disposal site through clayey sand soil. This occurs at the depth range of few meters from the surface to greater than 20 m. The presence of the slightly conductive structure is a result of filtration of the contaminants by the soil materials which increased the resistivity of the soil. The movement of the contaminant through the soil is an indication of the porous and permeable nature of the farmland. The resistive structure is only noticeable in profiles 1 and 2 but very prominent at the depth range of 5 m to more than 20 m and 5 m to 35 m along the profile length. The results of the analysis of the five soil samples from the poultry farmland showed a high value of 0.552 and 3.554 x 10−2cm/s of porosity (Ф) and coefficient of permeability (K) respectively. A strong correlation of R
2 = 0.9878 existed between Ф and K. With these results geo-electrical method had successfully assessed Ф and K of the soil of the poultry farmland.

Authors: Can Sema , Demirkan Erkan , Çeviker Abdulkerim
Published: October 2021

Study aim: In this study, it is aimed to find out the exercise preferences based on the Body Mass Index (BMI) and Body Weight Perception (BWP), and to determine the consistency between BMI and BWP calculated via the self-reporting method.

Material and methods: The study was conducted total of 297 volunteers, included 174 females (Mage = 27.19 ± 9.94 years) and 123 males (Mage = 26.08 ± 10.15 years), who were members of the physical activity center. The height and body weight values were obtained based on the self-reports. BWP was assessed by asking “how do you describe your weight?” As a statistical analysis, the Pearson chi-square test and Kappa statistics were used.

Results: It was determined that overweight/obese female prefered most the strength exercises, whereas, overweight/obese men, according to both methods, preferred the different kind of exercises (p < 0.05). When the mutual consistency of the BWP and BMI methods was compared, “average” level conformity was found in female, and “weak” level conformity was found in male (Female: κ = 0.48; p < 0.000; Male: κ = 0.21; p < 0.001).

Conclusion: It could be said that the type and application protocol of the exercise has been related with the frequency and duration of the exercise for both of the methods. Besides, it could be said that there was a higher consistency among female participants at the level of participating to the exercise and they had similar exercise preference, frequency and duration.
Individual Prevention in Criminal Procedure
Authors: Lach Arkadiusz
Published: October 2021

This article explores the possibility of using criminal procedure and its measures for individual prevention of crime. The author tries to look at criminal procedure in an abstract way, not focusing on any concrete legal system. It is argued that the criminal process is traditionally reactive and this should not change. However, some measures of criminal procedure (arrest, pretrial detention, house arrest, suspension of driving licence, suspension at work) may be used as instruments of individual prevention when they are the best or only measures available and their application will not prejudice the case against the accused. Their use must be accompanied by relevant safeguards and allowed only if necessary and proportional.
An analysis of key factors affecting New Town Planning with a human-centred approach
Authors: Izadi Maliheh , Varesi Hamidreza , Vardanjani Mehdi Jafari
Published: October 2021

Since new towns are to meet the needs of the metropolitan population, it is required to acquaint the populations with the new scientific-technical methods and take one more step towards civilisation. Given that the New Town seeks to provide the latest facilities for citizens, a human-oriented approach can be proposed. New Urbanism with a humanistic approach requires coherent and dynamic planning. New structures and the various needs of the New Towns require comprehensive and integrated planning to utilise recent facilities to lead New Towns toward a human-centred attitude.

Therefore, the main purpose of this study is to analyse the key factors affecting the planning of New Towns with a humanistic approach. The method in this research is a descriptive-analytical survey. In the first step of the research, a list of primary factors involved in planning new cities was identified as research variables, using documentary sources and previous research. Then the research variables were analysed based on the Delphi method. Accordingly, 34 variables were provided in five domains for 50 experts in urban planning issues in the form of questionnaires to be analysed in matrices.

The findings of the study are demonstrated in five aspects: cultural-social, physical-spatial, economic, environmental, and governance topics, with 34 components. The results show that citizenship rights, social capital, transparency, accountability, law, participation, consensus, quality of performance and managerial effectiveness, efficiency, economic welfare, sustainable active economy, meeting economic needs, quality of texture, and spirituality have the highest impact and the lowest affectedness on the realisation of human-centred New Urbanism. The results can be useful and effective by establishing integrity and fundamental theoretical principles in planning, implementation and strategic control of New Towns.
Zipf's Law for cities: estimation of regression function parameters based on the weight of American urban areas and Polish towns
Authors: Sokołowski Dariusz , Jażdżewska Iwona
Published: October 2021

The paper aims at presentation of a methodology where the classical linear regression model is modified to guarantee more realistic estimations and lower parameter oscillations for a specific urban system. That can be achieved by means of the weighted regression model which is based on weights ascribed to individual cities. The major shortcoming of the methods used so far – especially the classical simple linear regression – is the treatment of individual cities as points carrying the same weight, in consequence of which the linear regression poorly matches the empirical distribution of cities. The aim is reached in a several-stage process: demonstration of the drawbacks of the linear parameter estimation methods traditionally used for the purposes of urban system analyses; introduction of the weighted regression which to a large extent diminishes specific drawbacks; and empirical verification of the method with the use of the input data for the USA and Poland

Authors: Orji Anthony , Ogbuabor Jonathan E. , Aza Gabriel Chiangi , Anthony-Orji Onyinye I.
Published: October 2021

This study investigates the impact of foreign direct investment on the level of firm technical efficiency in West Africa. Firms from Nigeria, Ghana, Sierra Leone and the Gambia were sampled due to the fact that they used to belong to the British Empire. The data, sourced from the World Bank enterprise survey, covers the period from 2006 to 2018, with the sampled countries having data for different years. A time varying stochastic frontier production function for panel was developed for this enquiry. The findings of the study show that foreign direct investment has a significant and positive impact on both technical efficiency and productivity of firms in West Africa. Controlling for other effects, international trade and firm size both have positive and significant effects on firm level technical efficiency. Therefore, policies should be aimed at encouraging more inflows and maintenance of the stock of foreign direct investment to avert divestments. This includes, but is not limited to, ensuring sociopolitical stability and introducing policies that would remove bureaucratic bottlenecks from the path of direct investment inflow and simplify the process of doing business in these countries.

Authors: Ferreira Paulo , Tilfani Oussama , Pereira Éder , Tavares Cleónidas , Pereira Hernane , Boukfaoui My Youssef El
Published: October 2021

This paper aims to analyse the connectivity of 13 stock markets, between 1998 and 2019, with a time-varying proposal, to evaluate evolution of the linkage between these markets over time. To do so, we propose to use a network built based on the correlation coefficients from the Detrended Cross-Correlation Analysis, using a sliding windows approach. Besides allowing for analysis over time, our approach also enables us to verify how the network behaves for different time scales, which enriches the analysis. We use two different properties of networks: global efficiency and average grade, to measure the network’s connectivity over time. We find that the markets under analysis became more connected before the subprime crisis, with this behavior extending even after the Eurozone crisis, showing that during extreme events there is an increase in financial risk, as found in the international literature.

Purpose

To investigate if first-year occupational therapy students who have had no on-campus, face-to-face learning experiences differed from second-, third- and fourth-year students in their perceptions and experiences of online learning during the Covid-19 pandemic.

Methods

One hundred and fifty-one occupational therapy undergraduate students (80.8% female; 66.2% 20–24 old) completed the Student Engagement in the e-Learning Environment Scale (SELES) and the Distance Education Learning Environment Scale (DELES). Analysis of variance (ANOVA) with bootstrapping was completed to examine the differences between first-year and senior students’ perceptions and experiences of online learning.

Results

Significant differences were observed across several SELES and DELES scales: peer collaboration (SELES) (p = .001), interactions with instructors (SELES) (p = .026), student interaction and collaboration (DELES) (p = .003), authentic learning (DELES) (p = .026) and active learning (DELES) (p = .013).

Conclusion

The findings demonstrate significant differences in first-year and senior students’ perceptions and experiences of online learning during the Covid-19 pandemic. The outcomes highlight the importance of facilitating collaborative and active engagement for all students by implementing academic, technological and social support measures within occupational therapy curricula.
A Novel Fast Feedforward Neural Networks Training Algorithm
Authors: Bilski Jarosław , Kowalczyk Bartosz , Marjański Andrzej , Gandor Michał , Zurada Jacek
Published: October 2021

In this paper1 a new neural networks training algorithm is presented. The algorithm originates from the Recursive Least Squares (RLS) method commonly used in adaptive filtering. It uses the QR decomposition in conjunction with the Givens rotations for solving a normal equation - resulting from minimization of the loss function. An important parameter in neural networks is training time. Many commonly used algorithms require a big number of iterations in order to achieve a satisfactory outcome while other algorithms are effective only for small neural networks. The proposed solution is characterized by a very short convergence time compared to the well-known backpropagation method and its variants. The paper contains a complete mathematical derivation of the proposed algorithm. There are presented extensive simulation results using various benchmarks including function approximation, classification, encoder, and parity problems. Obtained results show the advantages of the featured algorithm which outperforms commonly used recent state-of-the-art neural networks training algorithms, including the Adam optimizer and the Nesterov’s accelerated gradient.
Performance Analysis of Rough Set–Based Hybrid Classification Systems in the Case of Missing Values
Authors: Nowicki Robert K. , Seliga Robert , Żelasko Dariusz , Hayashi Yoichi
Published: October 2021

The paper presents a performance analysis of a selected few rough set–based classification systems. They are hybrid solutions designed to process information with missing values. Rough set-–based classification systems combine various classification methods, such as support vector machines, k–nearest neighbour, fuzzy systems, and neural networks with the rough set theory. When all input values take the form of real numbers, and they are available, the structure of the classifier returns to a non–rough set version. The performance of the four systems has been analysed based on the classification results obtained for benchmark databases downloaded from the machine learning repository of the University of California at Irvine.
Performance Analysis of Data Fusion Methods Applied to Epileptic Seizure Recognition
Authors: Ludwig Simone A.
Published: October 2021

Epilepsy is a chronic neurological disorder that is caused by unprovoked recurrent seizures. The most commonly used tool for the diagnosis of epilepsy is the electroencephalogram (EEG) whereby the electrical activity of the brain is measured. In order to prevent potential risks, the patients have to be monitored as to detect an epileptic episode early on and to provide prevention measures. Many different research studies have used a combination of time and frequency features for the automatic recognition of epileptic seizures. In this paper, two fusion methods are compared. The first is based on an ensemble method and the second uses the Choquet fuzzy integral method. In particular, three different machine learning approaches namely RNN, ML and DNN are used as inputs for the ensemble method and the Choquet fuzzy integral fusion method. Evaluation measures such as confusion matrix, AUC and accuracy are compared as well as MSE and RMSE are provided. The results show that the Choquet fuzzy integral fusion method outperforms the ensemble method as well as other state-of-the-art classification methods.

Authors: Cerpinska M. , Irbe M. , Pupurs A. , Burbeckis K.
Published: October 2021

The paper provides simulation results for SUP (Stand Up Paddle) board appendage resistance. Additional propulsion is added to the SUP board. It is equipped with a waterjet. The waterjet is attached to the board rudder. This increases the drag coefficient for rudder five times. To reduce the drag variable, design options for the waterjet duct were proposed. The simulation tests were performed using SolidWorks Flow software using two types of simulations, namely, the pressure on the body and the flow around the body. The objective was to streamline the bluff duct of the waterjet and thus to create the appendage design with minimum drag force from fluid flow and possibly greater Inlet Velocity Ratio. Calculations showed that rounding-off the edges of waterjet duct resulted in 35 % of drag coefficient reduction, while further streamlining reduced it by additional 10 %.

Published: October 2021

To increase the sensitivity and efficiency of a gas sensor, nanostructured ZnO and Co3O4 layers were obtained by hydrothermal synthesis directly on the electrode surface, eliminating the use of binders. Scanning electron microscope images showed that the resulting nanostructured coatings were characterised by good adhesion to the surface and high porosity, which opened up the possibility of their further use in the process of developing a gas sensor. The efficiency of the obtained nanostructured coatings and their sensitivity at room temperature to various concentrations of CO2 were determined. The resistance curves of the samples were obtained as a function of gas concentration in the chamber, for Co3O4 and ZnO nanostructures.

The importance of historical maps for man-made pond research: From the past extent of ponds to issues of the present landscape. A case study from the Czech Republic
Authors: Frajer Jindřich , Kremlová Jana , Fiedor David , Pavelková Renata , Trnka Miroslav
Published: October 2021

Historical maps are a valuable resource in landscape research. The information gathered from them facilitates the cognisance of landscapes and may assist current landscape planning. This study focuses on the historical occurrence and spatial extent of man-made ponds in the Czech Republic. Based on the 1st Military Survey maps (1764–1783) of the Habsburg Monarchy, we use Historical GIS to identify 7,676 man-made ponds in the historical landscape. Compared to the 2nd Military Survey maps (1836–1852), 56% of these man-made ponds had been drained. Such disappearances mostly affected large ponds in fertile agricultural areas, but also affected small reservoirs in less fertile areas at higher altitudes. As the current maps and spatial datasets (Water reservoirs, Landscape water regime, Farming areas) show, a number of these agricultural regions have been affected by climate changes and face water shortages. The historical map information of former ponds has the potential to contribute to their restoration in areas where water retention in the landscape needs to be increased.
From the agricultural station to a luxury village? Changing and ambiguous everyday practices in the suburb of Vinnytsia (Ukraine)
Authors: Gnatiuk Oleksiy , Mezentsev Kostyantyn , Provotar Nataliia
Published: October 2021

The study of everyday practices, self-identities and perceptions seems to be a promising approach to understand the suburban spaces as not only static containers but socially constructed, dynamic and ambiguous entities. Our case study is represented by the suburban village of Ahronomichne, located in the peri-urban area of the second-order Ukrainian city of Vinnytsia. The research methods included survey of residents (67 long-term residents and 59 newcomers), observations of the everyday activities of the residents and appearance of the build environment at seven observation points within the village, and four semi-structured in-depth interviews. We found that everyday practices of the long-term residents and newcomers significantly differ in terms of their set, spatial configuration and actual exercitation. The other important factors contributing to the variety of everyday practices and lifestyles are type of housing, age and family status. Simultaneously, we observed not just a combination but rather intertwining, mixing and hybridisation of urban, suburban and rural everyday practices and lifestyles. Another finding of the research was the western-type suburban growth of the second-order Ukrainian city in contrast to the largest cities of the country where centrifugal migrations of rich people to peri-urban area combines with the centripetal stream of less affluent migrant from peripheral settlements, keeping transitory residential strategy.
How are allotment gardens managed? A comparative study of usage and development in contemporary urban space in Germany and Poland
Authors: Szczepańska Magdalena , Kacprzak Ewa , Maćkiewicz Barbara , Poniży Lidia
Published: October 2021

This article aims to analyse the development and use of allotment gardens (AGs) and plots in Westphalia and Lippe (Germany) and Wielkopolska (Poland) to assess what functions are feasible in their current stage, thus, contributing to an ongoing discussion on the role of AGs in contemporary urban space. The analysis considered ecosystem services, green infrastructure and urban agriculture. Characteristic features of AGs were identified by means of a survey of plot-holders, in-depth interviews with representatives of allotment associations, and exploratory walks. The management and use of AGs differs in both regions in terms of accessibility, common areas, impact on the landscape and plots development. AGs in Westphalia and Lippe are accessible and developed in a way which meets needs of external users. They fit harmoniously into the surrounding landscape. However, AGs in Wielkopolska are not as accessible, prioritise internal users, and do not always blend in with their surroundings. In Westphalia and Lippe, in addition to recreational and edible plant-growing plots, there are also educational and integration ones, while in Wielkopolska main categories of plots were more numerous and varied; from recreational with a predominance of ornamental plants to fully-cultivated. However, the considerable freedom that Polish plot-holders enjoy gives rise to the gradual marginalisation of edible-plant growing.

Published: October 2021

The scheme of arrangement of grooves of partially regular microrelief of type II shifted by 0.5 angular pitch is considered. Such grooves are formed by vibration on end faces of rotary bodies. An analytical dependence was obtained to determine the relative area of a partially regular microrelief depending on the geometric parameters of V-shaped grooves. The parameters of the grooves of a partially regular microrelief formed at different distances from the center of rotation are determined, at which the value of the relative area of the partially regular microrelief formed on the treated surface will be stable.

Published: October 2021

The recuperative heat exchangers are an important part of the industrial plants. There are a number of such heat exchangers that differ in the arrangement of the streams. The knowledge of the flow arrangement of the streams is very important from a point of view of the heat exchangers calculations. There are various calculation methods, but only one takes into account the flow arrangement of the streams directly. The quantity that takes this into account is called the countercurrent index. The article deals with the determination of this quantity for a given recuperative heat exchanger.
Modelling Pedestrian Crossing Behaviour at a Midblock Section
Authors: Poojari Yugendar , Prashanth E. , Divya D. , Kalyani M.
Published: October 2021

In general, pedestrians want to cross a road at a mid-block section instead of intersections because it is the shortest route. According to an Indian scenario, most of the crosswalks in urban areas are not signalised and controlled. In this study, the crossing behaviour of pedestrians in terms of speed at a midblock section was studied by considering several parameters. Statistical tests such as ANOVA and Pearson correlation tests were performed in order to know the effect of parameters on the crossing speed of a pedestrian. The pedestrian’s age and gender, crossing type, pattern, time, number of stops, number of two wheelers, three wheelers, light and heavy commercial vehicles, and groups significantly affect their crossing speed. A multiple linear regression model was developed by considering the most significant parameters. The mean absolute percentage error, root mean square error, and R2 values were calculated to validate the models.
Measuring Control Delays at Signalized Intersections in Mixed Traffic Conditions
Authors: Sushmitha R. , Ravishankar K. V. R.
Published: October 2021

Control delay is the key performance indicator of a signalized intersection that defines the level of service. Several models have been developed in previous research work for estimating control delays, but many of them were based on homogeneous traffic conditions. In the present study, an Open Street Map (OSM) tracker mobile application was used to measure control delays from the field. A non-linear model was developed in the present study for estimating control delays in mixed traffic conditions using a MATLAB fitting tool. The field delay is compared with the developed non-linear model delay along with the Indian Highway Capacity manual (INDO HCM) and Highway Capacity Manual (HCM) models. The control delay estimated using the model developed in the present study shows a close relation with the field delay obtained using an OSM tracker when compared to that obtained using the INDO HCM and HCM models. Therefore, the OSM tracker mobile application can be used as a field control delay measuring technique.

STUDIJA PRIJEPOLJA KROZ ISTORIJU I TRANSFORMACIJA PARKA NARODNIH HEROJA
Authors: Rondić Šejla , Reba Darko
Published: October 2021

Prijepolje se u istorijskim doku­men­tima prvi put spominje 1332.godine, a spominje ga puto­pisac i diplomat Adam Gijom pišući o starim varošima i rudarskim mjestima. Međutim, Prijepolje se u dostupnim pisanim spomenicima prvi put javlja u ugovoru koga su Dubrovčani 7. jula 1343. godine zaključili s Arbanasima Burmazima o prenosu 100 tovara soli u trg manastira Mileševo u mestu zvanom »Prijepolje«. ,,Razvoju Prije­polja kao trga u značajnoj meri, između ostalog, doprineo je i njegov povoljan geografski položaj na raskrsnici puteva iz doline Lima preko Sjenice i Trgovišta prema Novom Brdu, Prištini, Trepči, i dalje prema Sofiji i Istan­bulu. Drugi deo puta išao je preko Višegrada, Goražda, Foče do Dubrovnika. Prijepolje nije bilo samo karavan­ska stanica u klasičnom smislu, odnosno mesto konačišta i odmora ljudi i konja nakon napornog puta. Tu su se sas­tajali trgovci i ponosnici, obavljani razni trgovački pos­lo­vi i isplaćivani ugovorni iznosi za razni prenos roba [5].

ODRŽIVOST PROIZVODNJE U USLOVIMA PANDEMIJE
Authors: Milivojev Dragana
Published: October 2021

Pandemija uzrokovana virusom COVID-19 izazvala je niz promena u industrijskoj proizvodnji. Posebno su ugroženi principi održive proizvodnje. Javili su se problemi smanjenja reciklaže i povećanje otpada koji ranije nije bio zastupljen, kao što je medicinski otpad. Negativnom uticaju pandemije svedoči vidno uzdrmana automobilska industrija, kao i veliki broj neproizvodnih aktivnosti. Analitičkim pristupom dat je pregled potencijalnih mera kojima se može ublažiti uticaj pandemije na održivost proizvodnje, a koje su u skladu sa izmenjenim uslovima rada i poslovanja. Ove mere se u najvećoj meri odnose na digitalizaciju u svim oblastima, a naročito u upravljanju i tretmanu otpada.

„f(x)=osetljivost, performativna instalacija
Authors: Tatić Aleksandra
Published: October 2021

U master radu bavim se temom osetljivosti, kao glavnom funkcijom jednog ljudskog bića, sa jedne strane kao uzrokom, a sa druge kao posledicom interakcije sa okruženjem. Okvir za ovo istraživanje predstavlja pitanje percepcije stvarnog sveta, uticaj akcije u stvarnom svetu na unutrašnji svet, a zatim i posledice reakcija na stvaran svet. Ideja ovog rada jeste da poveže i pomiri ove pojmove i da prikaže njihov međusobni odnos, sa ciljem da približi shvatanje stvarnosti i svakodnevnog života osetljive osobe. Kao ishod teorijskog i umetničkog istraživanja, i bavljenja prethodno navedenim pojmovima, nastaje umetnički rad, instalacija „f(x)=osetljivost“, koja poziva publiku da na performativan način učestvuje u rekreiranju osećaja osetljivosti.

PYGAME PROGRAMSKA BIBLIOTEKA SA STANOVIŠTA GENERISANJA GRAFIČKOG PRIKAZA I SINHRONIZACIJE SA AUDIO ZAPISOM
Authors: Bućan Nikolina
Published: October 2021

Biblioteka PyGame se razvija još od ranih 2000. godina. Sami autori kažu da nije u pitanju najbolja biblioteka za programiranje igara, ali glavna prednost joj je to što je jednostavnija od drugih za korišćenje i pogodna je za učenje programiranja kroz interesantan svet računarske grafike i računarskih igara, koje danas igraju značajnu ulogu u životima pojedinaca, ali i celokupnog društva. Istorija video igara seže do 1948. godine kada je Tomas T. Goldsmit (Thomas T. Goldsmith) dobio ideju video igre i patentirao je. Može se reći da je od tada industrija video igara u konstantnom usponu i napretku. Video igre su namenjene uranjanju igrača u neku vrstu virtuelne stvarnosti. To se postiže pre svega vizuelno, ali može napraviti ogromnu razliku i biti veliko poboljšanje igre ako  vizuelni deo prate adekvatni audio zapisi.

Published: October 2021

Results of foreign and Russian studies indicate a higher mortality rate of patients with concomitant cardiovascular diseases (CVD) due to the new coronavirus infection COVID-19. It has been proven that arterial hypertension, as one of the significant risk factors for the development of concomitant cardiovascular diseases, is associated with a more severe prognosis of COVID-19. This article presents the results of modern studies and large meta-analyzes of necessity and safety of the use of blockers of the renin-angiotensin-aldosterone system in patients with arterial hypertension and COVID-19. The data of studies show that an angiotensin-converting enzyme inhibitor (ACE inhibitor) and a thiazide-like diuretic is a pathogenetically rational combination. It realizes various ways of lowering blood pressure by reducing the activity of the renin-angiotensin-aldosterone system, which is achieved by using an ACE inhibitor, and natriuresis due to diuretics. As an example, a highly effective fixed combination of drugs is considered, characterized by good tolerance, which consists of an ACE inhibitor lisinopril and a thiazide-like diuretic indapamide of prolonged action. The authors expressed the opinion that the appointment of the fixed combination drug Diroton Plus (Gedeon Richter) will contribute to effective control of blood pressure and organoprotection in conditions of increased thrombogenic and prooxidative potential, characteristic of COVID-19 both in the acute stage and within the post-COVID Syndrome.

Mineralocorticoid receptor antagonists have been successfully used for many years to treat patients with primary hyperaldosteronism, refractory arterial hypertension and chronic heart failure. The increased interest in this drug in recent years is due to new information about its antifibrotic and antiproliferative effects, both cardiac and extracardiac. The article also discusses the possibility of using spironolactone in patients with the new coronavirus infection SARS-CoV-2 (COVID-19).
