U ovom se radu analizira struktura glagolske sintagme u bosanskom jeziku te se nastoji odrediti bazni položaj upravnih članova sintagme, njihovih argumenata, ali i adjunkta. Ponašanje strukturnih elemenata koji čine glagolsku sintagmu u bosanskom jeziku i mogućnost njihovog pomjeranja prati se u procesu deriviranja površinske strukture rečenice koja sadrži elidirano mjesto. Različita ostvarenja elipse objašnjavaju se jedinstvenim položajem pojedinih strukturnih elemenata i njihovom mogućnošću da projiciraju zasebne maksimalne projekcije koje, u procesu deriviranja površinske strukture rečenice, mogu biti ili obuhvaćene elipsom ili izbjeći elidiranje. U vezi s tim, u radu se ukazuje na različito ponašanje pojedinih vrsta glagola u procesu VP elipse u bosanskom jeziku, te se uspostavlja paralela s istim strukturnim elementima u engleskom jeziku. U radu se analiza navedenih pojava zasniva na principima i parametrima generativnegramatike.

: The objective of this study was to test the inhibitory effect of five newly synthesized arylmethylene-bis(3-hydroxy- 5,5 -dimethylcyclohex-2-en-1- one) derivatives. The structural characterization and stereochemistry of synthesized compounds were deduced from analyses of experimental FT- IR, 1 H, 13 C NMR spectra and theoretical methodology of DFT study based on the global chemical reactivity indices calculated using the 6- 31G** level of theory. the stability of the newly synthesized compounds, the reactivity descriptors obtained at B3LYP level ( E gap , dipole moment, μ , η , ω ) were computed. The docking study and the selected quantum chemical descriptors computed for compounds 1 −5 exhibit a good agreement. The strongest inhibitors showed 25 to 30 % inhi bition of tyrosinase activity. Results were supported by docking studies of the binding of the strongest inhibitors to the enzyme. The results suggest that tetraketones of this type, due to their tyrosinas e inhibitory effect, represent potential agents in the treatment of various types of melanomas and skin hyperpigmentation. 189.42 3´), 190.75 - C -1´).

Europe, with all its common sights, has an enviable wealth of history and cultural heritage. With its many monuments, sites, traditions, history, art, and culture, it has always attracted curious views and tells centuries-old stories to many tourists and visitors. At the heart of Europe, Bosnia and Herzegovina (BiH), founded in the 11th century, with its picturesque past, has always been at the crossroads of faith and civilizations. The key audience of tourism in BiH are nature lovers, adventurers and young and digital nomads, who represent great potential for the development of this sector given their nature of work, to be able to work from any location, and during the COVID-19 period. Furthermore, the importance of the diaspora for the development of tourism in BiH goes beyond tourist visits and helps BiH on its path to digital transformation. Digital tourism refers to how we use digital tools to organize, manage and even enjoy the travel experience. It uses all of the tools of digital transformation to change how we travel and experience different sites. Through digitalization, we want to reach every individual who passes through this country and further attract lovers of European history and culture, offer them a different, more creative, and innovative approach to learning about the cultural and historical treasures it hides. The goal of digital tourism is to raise awareness of the importance of cultural heritage, provide new opportunities for visitors and bring new knowledge. Therefore, this paper provides an overview of the possibilities of digital representations of the medieval historical period of BiH through identified pillars of digital reconstruction, and ways to connect the movable cultural heritage residing in the museums with real sites in an attempt to contribute to its promotion through digital tourism. © 2022 Copyright for this paper by its authors.

Eduard von Keyserling wird schon von seinen Zeitgenossen, aber auch während der späteren Rezeption als Autor aufgefasst, dessen Werke thematisch um den kulturellen Verfall seines eigenen Milieus, des deutsch-baltischen Adels, kreisen. Der schwerkranke und blinde Keyserling erscheint dabei selbst als letzte Sprosse seiner Familienlinie. Der deutsch-baltische Adel erweist sich als eine Gesellschaft, die wegen der jahrhundertealten, fast unveränderten Lebensweise beim Aufbruch der Moderne ihrem Untergang entgegenläuft. Die Verfallsstimmung lässt sich dabei durch verschiedene Anzeichen bemerken. Das familiäre und gesellschaftliche Leben dieser Menschen wird von einer Ordnung geprägt, deren Beschützer und Befürworter die alten Schlossherrschaften sind. Diese psychisch immer noch starken Menschen verlieren jedoch an Lebenskraft und blicken oft als Schwerkranke dem bevorstehenden Tod entgegen. Die Pflege der Tradition soll daher an die jüngere Generation vermittelt werden, die jedoch dieser Aufgabe nicht gewachsen ist. Die Jugend hat ebenfalls mit verschiedenen psychischen oder physischen Krankheiten zu kämpfen. Überempfindlichkeit, Reizhunger oder Neurose treiben diese jungen Menschen aus der zwar geborgenen, aber betrübenden familiären Umgebung oder schließen sie noch fester innerhalb der Schlossmauern ein, sodass jegliche äußeren Einflüsse als Bedrohung erscheinen. Beide Fälle sind dabei durch die Verneinung der Wirklichkeit zum Scheitern verurteilt. Als misslungen erweisen sich ebenfalls die häufigen Bestrebungen, über die eigene Sensibilität und Kränklichkeit durch den Genuss des häuslichen Komforts hinwegzutäuschen. Keyserling schildert eine Gesellschaft, die den eigenen Verfall mit einem Schleier des ästhetisch Schönen zu bedecken versucht, dabei jedoch von der Realität immer wieder eingeholt wird.

The use of renewable energy sources is imposed as an imperative for the competitiveness and stable energy policy of companies. The basic production equipment in the "Kreka" coal mine in Tuzla has electrical plants with a total peak load of 12 MW, and the costs for electrical energy exceed €3.5 million annually. The paper analyzes the suitability of infrastructure facilities and devastated areas of the Kreka Coal Mine in Tuzla for the construction of photovoltaic power plants and the effects of such plants. The results of the analysis show a significant resource for the installation of photovoltaic power plants with a capacity of 230 MW. The production of electricity from these photovoltaic power plants enables a reduction of emissions into the air by 190 t/year of particle emissions, by 316.2 •103 t/year of CO2 emissions, by 58.15 t/year of SO2 emissions and by 251.9 t/year of emissions NOx. With the subsidized purchase of electricity, it is possible to return the investment within 6 years.

We observe the relationship and causality between cryptocurrencies on one, and commodities, currencies, equity indexes and web search results on the other side. We use prices of Bitcoin and Ethereum for cryptocurrencies, prices of crude oil and gold for commodities, Euro-US Dollar, Euro-Swiss Franc exchange rates for currencies, Dow Jones Industrial Average for market index and Google Trends® data as a measure of worldwide web search results for cryptocurrencies of interest. We find that Bitcoin and web search results correlation went from highly positive to low negative during the COVID-19 period. The results of the study show that the price of Bitcoin and Ethereum can be modelled using different combinations of commodities, currencies, indexes and web search results, with web search results and Dow Jones Industrial Average exhibiting best predictive power both concurrently and one day in advance. Our best performing models were able to explain more than 95% and 90% of Bitcoin and Ethereum price variability respectively. We also find strong evidence of web search traffic impacting both Bitcoin and Ethereum prices at all tested lags, as well as some evidence of gold impact on Bitcoin and EUR/CHF impact on Ethereum.

Optical character recognition represents the mechanical or electronic conversion of handwritten, typed or printed images into coded text. Optical character recognition is widely used as a form of data entry from records that have been printed, and it can include invoices, bank statements, passports and many more. In the research, Optical character recognition reads data from the Re-Captcha dataset of images, converts them into strings, and these strings are used for testing, training and calculating prediction accuracy. The methodologies used are Convolutional neural network and Recurrent neural network. The convolutional neural network consist of neurons that receive data and group them according to similarity. A recurrent neural network cycle can be created between the connections of nodes, allowing the output from nodes to influence the subsequent input to other nodes. For data were used Re-Captcha images, and for the prediction of characters from images was used TensorFlow with Keras. The best results that are produced can be compared between first and last result, where the loss for first result was 20.63 and value loss was 16.45, while last result has loss of 0.56 and value loss of 2.96

There is a growing technological development in intelligent teaching systems. This field has become interesting to many researchers. In this paper, we present an intelligent tutoring system for teaching mathematics that helps students un-derstand the basics of linear programming using Linear Program Solver and Service for Solving Linear Programming Problems, through which students will be able to solve economic problems. It comes down to determining the minimum or maximum value of a linear function, which is called the objective function, according to pre-set limiting conditions expressed by linear equations and inequalities. The goal function and the limiting conditions represent a mathematical model of the observed problem. Working as a professor of mathematics in high school, I felt the need for one such work and dealing with the study of linear programming as an integral part of mathematics. There are a number of papers in this regard, but exclusively related to traditional ways of working, as stated in the introductory part of the paper. The center of work as well as the final part deals with the study of linear programming using programs that deal with this topic.
