Gun powder is predicted to be more expensive in relation to the world oil shortage crisis in the future. However, cellulose (generic chemical formula (C6H10O5) is the carbohydrate that makes up the main structure of plants. It is more economical especially for countries with a lot of natural resources and rain forests like Malaysia. The finding of the study reveals the capability of nitrocellulose as gunpowder. In this research, a comparison of the same mass of nitrocellulose and gunpowder is made to find out which propellant produce longer distance and greater impact. The main objectives of this study are to find out the performance and capability of nitrocellulose extracted from Rhizophora apiculata compared to gunpowder in terms of velocity, calorific value of bullets and kinetic energy produced. The result shows that the nitrocellulose has better performance than gun powder. The new application of smokeless gun powder ensures troops especially snipers hardly being detected by enemy and at the same time improves safety and security level.

The development and the progress of media communication at the present is a fact of the knowledge and the technology development that must be accepted. It presence like the flowing water which has a fast current that brings also two influences both positive and negative that must be accounted for the members of the Catholic Students Community Of St. Martinus Ende (KMK St. Martinus Ende). Both positive and negative influences the media community like a kinetic energy or a power attraction that attract  them in a tiring ambiquity. Let them walk alone without escort of a decisive compass where they should have a rightist attitude and responsible. On the point, the guidance and assistance of the church is an  offering  if the church will be born a generation  of the future  of the  church  that is mature and has a certain quality  based  on the growth  and the development  of acuteness and inner  to determine the attitude to the development of media communication. The process of sharpening of mind and the sharpeness of the participants can be realized by giving some activities such as: awareness, deepening and even  the sharpeness of the actor of  media communication as an  alternative of reporting work of the God Kingdom for human beings. It becomes the main moving spirit or activator  for the board of KMK Of St. Martinus Ende  to plan and boring  about the activity of catechism. The activity rise the method of Amos.  By this method, the participants are invited to build a deeply reflection that based on thein real experiences about the media communication, while keep on self opening to the God planning will come  to them  and  give them via  the commandment of God.  The commandment  of God  come to light, inspiration, motivate, power and critics to the  participants about the using of the media communication as a media of the commandment of the kingdom of God  to the world that is more progress and development lately.

The world is going green; hence, environmentally friendly practices that would conserve natural resources for the future generation are encouraged. As a consequence, the world is less concerned about the numerous applications of nanotechnology, especially in the health sector; rather, it is more concerned about the sustainability of functionalized nanomaterials. Thus, the future of nanotechnology depends on its ability to ‘go green'. Green nanotechnology attempts to synthesize improved, nontoxic, and biocompatible nanomaterials with sustainable benefits using eco-friendly materials. Although green nanotechnology is considered a sustainable, viable, and biocompatible approach to the production of eco-friendly nanomaterials, there are shortcomings especially in microbial handling and process optimization. In this chapter, the authors aim to appraise not only the use of biocompatible approaches for the synthesis of nanoparticles and/or nanomaterials but also their shortcomings.

While developed countries of the world are expressing growing concern about the plight of tropical rain-forests, it is necessary to understand the issues involved. They are not merely populaton growth, the world food problems, and the ever-growing demand for natural resources, but also environmental ethics and the attitudes of resource managers and other decision-makers. These last issues might be even more important in the long run than purely demographic and socio-economic problems.The Author of this essay attempts to build up a case for the need of a global environmental ethic which would incorporate existing values of respect for living creatures, sacred groves, and sacred animals—such as still survives among the cultures of the less-developed parts of the tropical world. It might well be that the life-styles of strongly vegetarian societies, and the intensive tropical lowland agriculture as practiced in and around irrigated rice-fields in Southeast Asia, could be used as a model for wiser use of renewable natural resources in the lessdeveloped tropical areas.

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.

My contribution to the crusade for the perpetuation of all life on Earth, indeed for the very tools for survival if the situation becomes more critical, has been the opportunity to put the case for conservation of Nature and natural resources over to the public in general, and also to present it to the great decision-makers of our time—the men and women who have such mighty power for good or evil, and on whose vision and actions the future of Man depends. I have been able to do this because of the dedicated support I have received from my colleagues in the World Wildlife Fund (WWF), and from our sister organization and scientific adviser, the International Union for Conservation of Nature and Natural Resources (IUCN), all working in close partnership.

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.

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.
