<p>La lengua de vaca (<em>Rumex crispus L.</em>) y la gualola (<em>Polygonum segetum </em>HBK.), son espécies de malezas comunes que crecen en las áreas subtropicales del mundo donde ocasionan grandes pérdidas en cosechas y praderas debido a su agresividad. En Colombia se encuentran en zonas ubicadas por encima de los 2000 msnm, y son muy difíciles de manejar por su alta competitividad y gran habilidad para propagarse, tanto sexual como vegetativamente; a menudo crecen solas en un campo gracias a su capacidad para prevalecer sobre otras especies de plantas. Con el fin de estandarizar una metodología para la extracción e identificación de algunas sustancias provenientes del metabolismo secundario de las dos especies citadas, se realizaron experimentos para evaluar  el efecto de tales compuestos sobre la geminación y desarrollo de especies agrícolas.  A través de bioensayos se estableció que los extractos acuosos de hojas y raíces contenían varias sustancias alelopáticas: flavonoides, 5-deoxiflavonas, 7-8-dihidroflavononas y ácidos ferúlico, caféico y sinápico. Los extractos etanólicos de plántulas de <em>Rumex crispus</em>, en tres estados de crecimiento, permitieron confirmar la presencia de flavonoides, terpenos, sesquiterpenlactonas, quinonas, glicósidos y cumarinas, pero no de alcaloides. Por otra parte, mediante la utilización de células de <em>Rumex crispus </em>en suspensión, se logró aumentar la producción de flavonoides. El conocimiento de la eficacia de las sustancias alelopáticas de estas especies y su uso potencial puede llegar a ser de gran utilidad en programas de manejo de las relaciones planta-planta.</p><p> </p><p><strong>Some studies on allelopathy of </strong><strong><em>Rumex crispus </em></strong><strong>L. and </strong><strong><em>Polygonum segetum </em></strong><strong>HBK., in Colombia</strong></p><p>Curly dock (<em>Rumex crispus</em>, ‘lengua de vaca’) and smartweed (<em>Polygonum segetum</em>, ‘gualola’), are two common weed species that grow in subtropical areas of the world, where cause great losses in crops and grasslands due to their aggressiveness. In Colombia they are found on lands over 2000 m.o.s.l., and as they propagate by both, sexual and vegetative ways, it is very difficult to manage them. Several experiments were carried out in order to standardize the extraction methods, identify the extracts due to secondary metabolism from plants of <em>Rumex </em>and <em>Polygonum</em>, and evaluate the effects of such compounds over the germination and development of various species of plants. It was possible, through bioassays, to establish that watery extracts from the leaves and the roots contain allelopathic substances that increase the competitive ability of these weed species. On the other hand, qualitative analyses allowed identifying several allelopathic compounds like flavonoids. Initial bioassays were conducted over three groups of plants of <em>R. crispus </em>through experiments with ethanolic extracts and colored tests that confirmed the presence of flavonoids, terpenes, sesquiterpenlactones, quinones, alcaloids, glycosides and cumarines in plants of smartweed in those three growth states. Chalcones, aurones and flavonoles were detected as well as antraquinone and terpene glucosides, but not so, alcaloides.These results could become useful for advancing studies since they amplify the knowledge about allelopathic substances of these weed species, and show their potential use in managing plant-weed relation programs.</p>

The sphere of fitness develops dynamically and is one of the most profitable in the world and, as a result, investment attractive. Nevertheless, the competitive ability of a fitness club depends on the speed with which the new directions are introduced in it and what range of services they provide to clients. That is why it is important to be able to foresee the most popular trends and the ways of their adaptation to a concept of a particular fitness club. The objective - comparison of world and national trends and an attempt to evaluate tendencies of fitness industry development in Ukraine. Methods. The research is based on the analysis of sources of literature as well as thoughts of experts concerning perspectives of fitness development in Ukraine. Results. The comparison of the world and national (the USA, China, Spain) trends of 2018 has allowed to discover that world trends reflect the USA trends by 95% and only by a half – trends of the other represented countries. It is connected with the fact that in the research for revealing of the world trends out of representatives of 41 countries – 91,3 % respondents are from the USA. The author does not highlight this in the original article. The present fact proves the necessity of research of national trends specifically and not to focus on the «world» tendencies, as they reflect development prospects mostly in one country (USA). This statement is true and for the trends of 2019, because the study of this issue in Spain coincides with the results of the world rating only by 60 %. Conclusions. Such researches have not been conducted in Ukraine, but specialists stress the growth in the popularity of such directions in the future: child fitness, fitness for older adults, experienced and educated fitness professionals, exercise and weight loss, securing safety and quality of fitness services, nutrition guidance (trends are presented in no particular order). In general, fitness professionals consider the necessity of forming fitness culture among the population of various cities and villages of all the regions in Ukraine to be an overriding necessity for the development of the fitness sphere.

The inundative application of conidia of the plant pathogenic fungus, Rhynchosporium alismatis, to seedlings of Sagittaria pygmaea, S. guyanensis, and Alisma canaliculatum resulted in seedling death or significant growth suppression. In quarantine pot trials, inoculation of S. guyanensis seedlings caused reductions in average plant height of 60% and reduced leaf and root dry weights, by 89 and 84%, respectively. There was also high seedling mortality. Smaller, though significant, reductions in various growth parameters occurred in the other species when similarly inoculated. Alisma canaliculatum, Echinodorus rostratus, S. brevirostra, S. guyanensis, and S. pygmaea are recorded as new hosts of the fungus. The data indicate the potential use of this fungus as a mycoherbicide in temperate rice crops. Research is continuing on virulence and formulation to improve mycoherbicide efficacy.

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.

AbstractIslamic Law is one of the broadest and most comprehensive systems of legislation in the world. It was applied, through various schools of thought, from one end of the Muslim world to the other. It also had a great impact on other nations and cultures. We will focus in this article on values and norms in Islamic law. The value system of Islam is immutable and does not tolerate change over time for the simple fact that human nature does not change. The basic values and needs (which can be called maṣlaḥa) are classified hierarchically into three levels: (1) necessities (Ḍarūriyyāt), (2) convenience (Ḥājiyyāt), and (3) refinements (Kamāliyyāt=Taḥsīniyyāt). In Islamic legal theory (Uṣūl al‐fiqh) the general aim of legislation is to realize values through protecting and guaranteeing their necessities (al-Ḍarūriyyāt) as well as stressing their importance (al‐ Ḥājiyyāt) and their refinements (taḥsīniyyāt).In the second part of this article we will draw attention to Islamic norms. Islam has paid great attention to norms that protect basic values. We cannot explain all the Islamic norms that relate to basic values, but we will classify them categorically. We will focus on four kinds of norms: 1) norms (rules) concerned with belief (I’tiqādiyyāt), 2) norms (rules) concerned with law (ʿAmaliyyāt); 3) general legal norms (Qawā‘id al‐ Kulliyya al‐Fiqhiyya); 4) norms (rules) concerned with ethics (Wijdāniyyāt = Aḵlāqiyyāt = Ādāb = social and moral norms).
