Bacterial cellulose is a new pattern material produced by microorganism, because it has unique physical properties, chemical characteristics and mechanical properities, so it’s widely applied into food, biomedical, textile and many other kinds of industry. On the other side, because it’s a kind of pure natural biopolymer produced by microorganism, so the cellulose has biological activity, biodegradability and biocompatibility etc of excellent characteristics. It has been proved that bacterial cellulose is a biological environmental protection type material, so it becomes the hotspot of many researches and applications all over the world. This paper summarized the method of screening the cellulose-producing strain, how to make the bacterial cellulose yield increase, and the bacterial cellulose’s important applications in different industries.

Environmental protection has become a burning issue which plays a more and more important role in the world. The aim of this study is to give a picture of the constitutional regulation of environmental protection which is the highest legal source of a nation. Besides the Hungarian Fundamental Law, the German, Italian and Belgian constitutions were examined in the study. On one hand, we looked into how environment is regulated in the constitutions, as a right (right to environment) or a state task or objective (protect the environment). On the other hand, we analysed how related regulatory subjects appear in the constitutions, such as natural resources, future generations and sustainable development.

Bioplastics are biodegradable polymers that are made by bacterial cells, whose molecules have biochemical properties similar to petrochemical polymers as they are concentrated inside intracellular granules as a carbon and energy sources, and which then degrade in the environment as they get exposed to light. Bioplastics have desirable biodegradable and renewable qualities, sustainable qualities as well as alternatives to petroleum-based plastics, and is used due to much of its biodegradability and durability. Due to their vast usefulness, Poly Hydroxy Alkanoate (PHAs) and their derivatives are used in many different sectors, PHAs are the most biodegradable bioplastics found throughout the world. These polymers are generated by microorganisms through metabolic pathways that start with hydroxy-acyl-A and end with different types of acyl-A. Bioplastic polymers have chemical characteristics that differ in structural and physical properties which also differ due to the source of their polymerization microorganisms.

Little attention has been paid to the bryophytes as sources for human diet despite of the presence of 23000 species in the world. Some mosses contain vitamin B1, tocopherols, prostaglandin-like highly unsaturated fatty acids and phenolic compounds. On the other hand, liverworts contain enantiomeric mono-, sesqui- and diterpenoids to those found in vascular plants. Additionally, they possess bibenzyls, bis-bibenzyls and polyketides, many of them showing various bioactivity such as antimicrobial, antiviral, anti-inflammatory, cytotoxicity against cancer cell lines, muscle relaxing, antioxidant and other. In this paper, the structures of phytochemicals from bryophytes and their biological activities will be discussed.

There are two most inevitable issues on national literature, in this case Indonesian literature. First is the translation and the second is the standard of world literature. Can one speak for the other as a representative? Why is this representation matter? Does translation embody the voice of the represented? Without translation Indonesian literature cannot gain its recognition in world literature, yet, translation conveys the voice of other. In the case of production, publication, or distribution of Indonesian Literature to the world, translation works can be very beneficial. The position of Indonesian literature is as a part of world literature. The concept that the Western world should be the one who represent the subaltern can be overcome as long as the subaltern performs as the active speaker. If the subaltern remains silent then it means it allows the “representation” by the Western.

The main objective of this study is the substantiation of experiment as one of the key features of the world music in Ukraine. Based on the creative works of the brightest world music representatives in Ukraine, «Dakha Brakha» band, the experiment is regarded as a kind of creative setting. Methodology and scientific approaches. The methodology was based on the music practice theory by T. Cherednychenko. The author distinguishes four binary oppositions, which can describe the musical practice. According to one of these oppositions («observance of the canon or violation of the canon»), the musical practices, to which the Ukrainian musicology usually classifies the world music («folk music» and «minstrel music»), are compared with the creative work of «Dakha Brakha» band. Study findings. A lack of the setting to experiment in the musical practices of the «folk music» and «minstrel music» separates the world music musical practice from them. Therefore, the world music is a separate type of musical practice in which the experiment is crucial. The study analyzed several scientific articles of Ukrainian musicologists on the world music; examined the history of the Ukrainian «Dakha Brakha» band; presented a list of the folk songs used in the fifth album «The Road» by «Dakha Brakha» band; and showed the degree of the source transformation by musicians based on the example of the «Monk» song. The study findings can be used to form a comprehensive understanding of the world music musical practice. The further studies may be related to clarification of the other parameters of the world music musical practice, and to determination of the experiment role in creative works of the other world music representatives, both Ukrainian and foreign. The practical study value is the ability to use its key provisions in the course of modern music in higher artistic schools of Ukraine. Originality / value. So far, the Ukrainian musicology did not consider the experiment role as the key one in the world music.

The paper celebrates the publication of Ranjan Ghosh and J. Hillis Miller's Thinking Literature across Continents as a significant event in the age of neoliberalism. It argues that, in spite of the different premises and the resulting interpretative procedures respectively championed by the two co-authors, both of them anchor their readings of literary texts in a concept of literature that is diametrically opposed to neoliberal rationality, and both impassionedly safeguard human values and experiences that resist the technologisation and marketisation of the humanities and aesthetic education. While Ghosh's readings of literature offer lightning flashes of thought from the outside of the Western tradition, signalling a new culture of reading as well as a new manner of appreciation of the other, Miller dedicatedly speaks and thinks against the hegemony of neoliberal reason, opening our eyes to the kind of change our teaching or reading of literature can trigger in the world, and the role aesthetic education should and can play at a time when the humanities are considered ‘a lost cause’.

Most studies of Simone de Beauvoir situate her with respect to Hegel and the tradition of 20th-century phenomenology begun by Husserl, Heidegger, and Merleau-Ponty. This book analyzes The Second Sex in light of the concepts of becoming, problematization, and the Other found in Gilles Deleuze. Reading Beauvoir through a Deleuzian lens allows more emphasis to be placed on Beauvoir's early interest in Bergson and Leibniz, and on the individuation of consciousness, a puzzle of continuing interest to both phenomenologists and Deleuzians. By engaging with the philosophical issues in her novels and student diaries, this book rethinks Beauvoir’s focus on recognition in The Second Sex in terms of women’s struggle to individuate themselves despite sexist forms of representation. It shows how specific forms of women’s “lived experience” can be understood as the result of habits conforming to and resisting this sexist “sense.” Later feminists put forward important criticisms regarding Beauvoir’s claims not to be a philosopher, as well as the value of sexual difference and the supposedly Eurocentric universalism of her thought. Deleuzians, on the other hand, might well object to her ideas about recognition. This book attempts to address those criticisms, while challenging the historicist assumptions behind many efforts to establish Beauvoir’s significance as a philosopher and feminist thinker. As a result, readers can establish a productive relationship between Beauvoir’s “problems” and those of women around the world who read her work under very different circumstances.

Modernism is usually defined historically as the composite movement at the beginning of the twentieth century which led to a radical break with what had gone before in literature and the other arts. Given the problems of the continuing use of the concept to cover subsequent writing, this essay proposes an alternative, philosophical perspective which explores the impact of rationalism (what we bring to the world) on the prevailing empiricism (what we take from the world) of modern poetry, which leads to a concern with consciousness rather than experience. This in turn involves a re-conceptualisation of the lyric or narrative I, of language itself as a phenomenon, and of other poetic themes such as nature, culture, history, and art. Against the background of the dominant empiricism of modern Irish poetry as presented in Crotty's anthology, the essay explores these ideas in terms of a small number of poets who may be considered modernist in various ways. This does not rule out modernist elements in some other poets and the initial distinction between a poetics of experience and one of consciousness is better seen as a multi-dimensional spectrum that requires further, more detailed analysis than is possible here.

In several late texts, Derrida meditated on Paul Celan's poem ‘Grosse, Glühende Wölbung’, in which the departure of the world is announced. Delving into the ‘origin’ and ‘history’ of the ‘conception’ of the world, this paper suggests that, for Derrida, the end of the world is determined by and from death—the death of the other. The death of the other marks, each and every time, the absolute end of the world.

The Treaty establishing a Constitution for Europe ads territorial cohesion as Union’s third goal, beside economic and social cohesion and lists it as a shared competence. In the other hand, the Lisbon Strategy aims to turn Europe into the most competitive area of sustainable growth in the world and it is considered that the Territorial cohesion policy should contribute to it. This paper is structured by a descriptive language while deduction method is used. It refers to official documents, strategies, agendas and reports, as well as books, articles and assessments related to topic. This paper covers all of two Territorial Agendas as well as the background of territorial cohesion thinking and setting process of territorial cohesion policy.
