Nanocatalysts, as a part of nanotechnology, have been seen very useful for various fileds of applications capturing a large contribution of the world market. Indeed, several unsolved issues of catalysts have been reconsidered by employing the new nanocatalysts including single core metal atoms and ions with surrounding holes. Moreover, it was expected that the future of catalytic reactions, especially those organic ones, will deal with the nanocatalyst applications. To this aim, the features of catalytic nanoparticles and magnetic nanocatalysts regarding evaluation of their advantages and applications in organic reactions were investigated in this work. Developments of catalytic nanoparticles and magnetic nanocatalysts were discussed in this work regarding the novel applications of such materials at the nanoscale for approaching advantageous features. Increased availability, activity, and stability are very important for applications of the catalysts in various organic reactions. Therefore, it is a must to discuss features of such nanocatalytic systems to provide more information about their advantages and even disadvantages of their applications.

AbstractThe novel COVID-19 global pandemic has become a public health emergency of international concern affecting 215 countries and territories around the globe. As of 28 November 2020, it has caused a pandemic outbreak with a total of more than 6,171,5119 confirmed infections and more than 1,44,4235 confirmed deaths reported worldwide. The main focus of this paper is to generate LTM real-time out of sample forecasts of the future COVID-19 confirmed and death cases respectively for the top ten profoundly affected countries including for the world. To solve this problem we introduced a novel hybrid approach AARNN model based on ARIMA and ARNN forecasting model that can generate LTM (fifty days ahead) out of sample forecasts of the number of daily confirmed and death COVID-19 cases for the ten countries namely USA, India, Brazil, Russia, France, Spain, UK, Italy, Argentina, Colombia and also for the world respectively. The predictions of the future outbreak for different countries will be useful for the effective allocation of health care resources and will act as early-warning system for health warriors, corporate leaders, economists, government/public-policy makers, and scientific experts.

The paper presents the analysis of genre definition of Pekić’s prose. Genre definition of the prose work The time of miracles is mainly analysed and explained, which theoreticians define differently, determining it as a chain, stories, but also as a novel. The analysis of the corpus, that is, the works The time of miracles and New Jerusalem is conducted through the prism of Bakhtin’s theory on the novel, with a brief resistance of Lukacs’ theory to Bakhtin’s when it comes to the analysis of Pekić’s prose. After the explanation of the characterisation of The time of miracles as a novel, we deal with chronotope, as genre definition, where the most common chronotopes that we encounter in Pekić’s prose are indicated. The novelties that Pekić brings to Serbian literature are reflected in one complete novelistic image, a parallel world, documented by historical sources, the witness’ stories, archeological sites. Generally speaking, the central point of his work is occupied by problematising man’s position in the world in general – so, also in the past, present, but in the future as well. And precisely that and such his relation towards culture and existence – erudite, problematising, predictive, revealing – is “analogous to the correlations between chronotope within the work“ (Bakhtin, 1989, p. 386).

The paper aims to show how the traditions of science fiction and, above all, invasion literature provide the ideological background for reading Andrew Hunter Murray’s The Last Day as a novel about Brexit. As it draws on anxious visions of the future, in which the enemy lurks around every corner, and the only salvation is complete isolation from the world, Murray’s work is read here as a Brexit dream come true, in which Britain is once again great, independent and uncontaminated by foreign elements. By evoking the myths that focus only on glory and conveniently “forget” the dark sides of the empire, the novel demonstrates that the fantasies of the past are as distant as the fantasies of the future; the loss of the world that never was is reworked in The Last Day into the loss of ecologically viable planet.

This publication presents regular materials of the scientific workshop "Modern Development Problems", which is held in the Center for Development and Modernization Studies of IMEMO RAN. Common patterns and national specifics of new industrial countries, their experience and development trends as a launching base for forecasting of the future role and the meaning of these substantial actors on the world market, as a possible choice of evolution in other states of the Pacific Asia, the meaning of which in the world economy will increase in the visible perspective, are analyzed.

In this article, I draw on William S. Burroughs’ The Western Lands to think about what François Laruelle has termed a “generic humanity.” This generic humanity broadens and expands our ethical obligations towards those who have not yet been included in humanity. Burroughs’ emphasis in the novel on flattened time, magic, and death as transformation is used to show how we can make Mankind extinct from our way of thinking. Burroughs’ novel is thus an example of a “philo-fiction,” a work of literature that allows us to see the world differently.

The novel Les Larmes, by French writer Pascal Quignard, takes place in the ninth century, two twin brothers make totally different choices of life. Hartnid is always on the go. His twin, Nithard, is a pure scholar. His life is devoted to language. It is precisely his involment in language that allows him to write something that was never written before. He writes the Serments de Strasbourg (English: Oaths of Strasbourg, Latin: Sacramenta Argentariae) in 842, first written marks of a language that will become the French language. This novel offers a unique opportunity to sketch a thought on the ability of literature to speak about our relationship to reality.   The first part of the article questions the gesture of the novelist who acts on himself and on reality when writing, he really tries to change the world. The second part of the article studies the notion of realism and shows how Quignard finds a place in the history of literature that, today, stays away from realism, but, maybe, in order to better track down reality. Finally, in order to grasp the specificity of the Works of Quignard, my interest in the aesthetic of Les Larmes is threefold: its complex structure, the fascination for origin that it shows and, the question of identity and splitting with the twin brothers Hartnid and Nithard. The article concludes on the ability of artists to anticipate in their creations and, in advance, to tell about events that will occur in the future.

The literature in general and epidemiological literature especially represents the reflection of the health status of society and the health crises that the world has witnessed since ancient times. Those epidemics were the engine for many authors and novelists pens in particular. Thus, many novels touched on those diseases that caused violent shocks in the whole world, which left behind them many tragedies that remain stuck in the global memory. Since the novel is the mostrealistic literary art, it took the initiative to be the most prominent literary art that dealt with these topics and dealt with them, whether they were stories transmitted from reality or imaginary that predicted the future.

Abstract Competitiveness of the country is a very important factor, especially in the area of tourism. Tourism is one of the most important and most rapidly growing economy sectors, which faces the challenges and possibilities of globalization. The travel and tourism sector is widely recognized as an important factor for the regional development. This enables the country to be successful in the world market and for tourists. To measure the competitiveness of travel and tourism, we used various indexes. One of them is the Travel & Tourism Competitiveness Index, published by the World Economic Forum. The aim of this paper is to analyse the travel and tourism competitiveness in selected countries. According to their performance, we identified the best travel and tourism country. In addition, we focused on strengths and weaknesses of the analysed countries to improve their competitiveness position in the future.
