Cellulose Materials

Recently, due to the growing interest in powdered cellulosic materials, a large number of studies have been carried out on various methods of their preparation. The main interest is associated with new opportunities for research on nanocellulose. However, for a complete understanding, it is necessary to have information about all powdered cellulosic materials and the peculiarities of their preparation. This paper provides an overview of powdered cellulosic materials, presents their characteristics, and describes the properties of the materials. It is shown that the morphology of its fiber, as well as the ratio of crystalline and amorphous regions of cellulose, has a significant effect on the properties of the material. Peculiarities of obtaining powdered cellulose materials are discussed, depending on the required properties, and existing research in the field of mechanical, chemical and enzymatic processing of cellulose is presented. The main areas of application of various powdered cellulose materials are described, as well as the current situation on the market, examples of both domestic and foreign manufacturers are given. The information on powdered cellulose materials is generalized, their classification is given, which is consistent with the modern concepts described in the scientific works of researchers from all over the world.

Radical Transformation

 The author analyzes the conceptions of ontological nihilism in the works of S. Kierkegaard, F. Nietzsche, M. Heidegger, E. Jünger. On the basis of this analysis, violence is defined as a manifestation of nihilism, of the “will to nothingness” and hypertrophy of the self-will of man. The article demonstrates the importance of the problem of nihilism. The nihilistic thinking of modern man is expressed in the attitude toward a radical transformation of the world from the position of his “absolute” righteousness. The paradox of the current situation is that there is the reverse side of this transformative activity, when there is only the appearance of action and the dilution of responsibility. Confidence in the rightness of own views and beliefs increases the risk of the violent imposition of own vision of reality. Historical and philosophical reconstruction of the conceptions of nihilism allowed to reveal the following projects of its comprehension and resolution: (1) the project of “positing of values,” which consists in the transformation of the evaluation, which is understood as another perspective of positing values, leading to the affirmation of being; (2) the project of overcoming nihilism from the space of temporality, carried out through the resoluteness to accept the historicity of own existence; (3) the project of overcoming nihilism as the oblivion of being from the spatial perspective of the “line,” allowing to realize the “glimpse” of being. The author concludes that it is impossible to solve the problem of violence and its various forms of its manifestation without overcoming “ontological nihilism.” Significant role in solving the problem of ontological violence is assigned to philosophy as a critical and responsible form of thinking, which is capable to help a person to bear the burden of the world, to provide meanings and affirm being, as well as to unite people and resist the fundamentalist claims of exclusivity and rightness.

There is little research on elementary/secondary teacher preparation. Few teachers are called upon to teach astronomy specifically, or their astronomy teaching is peripheral to their main interest (e.g., general science at lower levels or physics at higher levels). Statistics indicate that large increases in student populations are expected throughout the world. “In 1997, 1.2 billion students were enrolled in schools around the world. Of these students, 668 million were in elementary-level programs, 398 million were in secondary programs, and 88 million were in higher education programs.” (Digest, 2002) These figures included large increases from the 1990 figures, e.g. 38% increase in secondary education and 68% in higher education for Africa, as opportunities to obtain an education and population both grew. (Digest, tables 395 and 412).

The high number of unemployment in Indonesia is caused by college graduates not brave enough to determine a career path as an entrepreneur. The embedded bad image and false myths about entrepreneurs has made its spread very low in Indonesia. Universities in Indonesia are looking for a more effective form of teaching entrepreneurship so as to produce graduates who are productive rather than educated, but unemployed graduates. Entrepreneurship is very unique because it contains multiple disciplines. There are various forms of teaching entrepreneurship used by different countries in the world from various literatures. Universities and entrepreneur lecturers should be able to take an example on (adapt and adopt) how to teach according to the college culture and taught students, without having to look at what disciplines the student is enrolled in, also by integrating the values of entrepreneurship in the curriculum and extracurricular activities as supporting activities. Thus, entrepreneurial atmosphere can be created within the campus so that students, during their stay in college, do not seem to have lived and becoming used to a dynamic entrepreneurial environment, inspiring, and full of innovation. Thus, graduates will be braver in becoming an entrepreneur without it becomes their last choice like the current situation.

New Perspective

The present book starts with an introductory chapter in which the contents of the previous book have been dealt with in a whole new perspective and the ways and means to move forward towards global peace have been delineated in the concluding chapter of the book. In the process, “Life, Mind, Brain, Cognition, Existentialism, Matter, Memory, Consciousness, Mysticism, Ontology, Psychology, Parapsychology, Ecology and Phenomenology” have been dealt with. This is followed by the discussion of “ Philosophy, Renaissance, Soul, Theosophy, Cosmology, Universe, The Witness and The Ultimate Truth”. It has been revealed that there is a whole new world of Existence on a new uncharted plane; the present day world-drama is not matured enough and not qualified enough with a sense of unselfishness to foster Global Peace. None-the-less, the destiny of the world and the whole human race, nay the entire manifested world is set to reach a spirited esoteric plane of Blissful Existence, this being a matter of eternity. The current situation in this planet is no more than a transitory phase.

In a time, when the economic crisis is filling the news, it may seem hard to even think about improvements in terms of research and development, since there are lacking funds even for the reproduction. However, the last economic revolution was born in a crisis. Therefore it is sensible to look at the current situation as an opportunity for the next economic revolution,. bringing the economy a new cycle of development. The potentials for growth with the globalization have been mainly exploited so far, bringing considerable negative consequences into our lives and our environment that have triggered anti-globalist and ecological movements around the world. Now it’s time to think how to make things better and more humane. The main goal of this chapter is to lay the foundation for an advanced-research technological platform for logistics applications networks.

This chapter outlines the current situation about homeschooling across the world today. It highlights its enormous growth over the last 40 or 50 years, since its reintroduction in the USA and the impact that has had on the world homeschooling movement. It describes the contested outcomes of home education, including the evidence that students' academic, social, and emotional outcomes are higher while also providing a solid basis for ‘graduates' of home education to experience success in adulthood. Theorizing the roots of this success, the chapter looks at the measures of success and the theoretical bases of the success of the mainstream schooled and explores how the features that make a successful graduate of mainstream schools are naturally and almost exclusively present in the home education setting, Finally, it considers how the current turn against home education and suggests how future research might be useful to counter these negative discourses about the practice while understanding this growing cohort of children across the world today.
