The transition from hunting and gathering to farming happened about 10,000 years ago, independently and diffusely in several places in the world. Plant breeders were responsible for genetic progress in a number of crop species. It included hybrids, the introgression of wild species genes and also the Green Revolution, which started in the 1960's with the cereals. The varieties developed by breeding, along with the use of new crop technology (fertilization, soil tillage, etc.) changed the status of some countries from importers to exporters of food. In the turn of the millennium,, plant breeding, faces new challenges in a globalized world, but it has new tools to deal with them. Notwithstanding the present contributions of plant breeding and crop management, its future contributions may be even greater. The partnership being developed between plant breeding and biotechnology will assure a more consistent and predictable genetic progress. Current contributions of biotechnology have arrived for many crops in different places of the world. Varieties developed by transformation are grown in large acreage in some countries. Some concerns have also arisen from the use of GMOs. For example, the introgression of a gene for insect resistance 4 into many different species could result in an undesirable endemic risk, here called interespecific biotechnological vulnerability. Another concern is that biotechnology race may create yield plateaus in programs using genes pyramiding for all new traits made available by biotechnology, resulting in what is called genetic gridlock. Nevertheless, the benefits of using biotechnology will substantially enhance the contributions of plant breeding to human life

The Russian intelligentsia at the beginning of the 20th century is characterized by a steady need for unity with the world. This need takes on an intertextual character, flowing into the interaction of ideas and cultural codes leading to the attainment of the status of Homo Cosmicus. One of these codes is a feast. The purpose of the author of the article is to reconstruct the lifecreation of the Russian intelligentsia at the beginning of the 20th century through the prism of an ancient feast. It seems that in the conditions of intense spiritual searches, in the struggle to find wholeness and completeness of human life, turning to antiquity became a truly metaphysical idea, where the feast was a significant cultural constant. In the process of moving to the highest point of spiritual development, the antique feast metaphorically reflects the cosmos of being, just as the violation of the order of the feast reflects the violation of the order of being. This is what happens in Russian reality in the first half of the 20th century, where against the backdrop of tragic historical events, the Platonic “feastˮ turns into the vulgar “feastˮ of Petronius. After the revolution of 1917 the intelligentsia, with its own aspirations, found itself at a feast alien to itself, where it could not find a place, and the “hangover” became too heavy and turned into a real drama. Methodological approaches to the problem under study are based on the theoretical basis of modern scientific knowledge, which includes concepts and methods of philosophy (N. A. Berdyaev, P. A. Florensky, D. S. Merezhkovsky, V. V. Rozanov, Vl. S. Solovyov), cultural studies (I. A. Edoshina, M. S. Kagan, Yu. M. Lotman, N. O. Osipova), art history (I. A. Azizyan, A. Payman, A. A. Rusakova, D. V. Sarabyanov), intelligentsia studies (V. S. Memetov, S. M. Usmanov).

Abstract Cultivated species, on which humankind depends for survival, have been created by farmers that have crossed and selected wild plants and developed landraces. Early in 20th century, the theory of Centers of Origin of Cultivated Plants was proposed by Vavilov. He also warned the world about the loss of plant genetic diversity due to the dominance of a small number of genetically similar crops, a fact that help starting a movement for the conservation of plant genetic resources. From this time, several strategies and institutions were established around the world to act in plant genetic resources (PGR) conservation. In Brazil, a remarkable player in PGR conservation, some institutions conserve several crop species as well as their wild relatives and other socio-economically valuable plant species. In this paper we present the status of PGR conservation in Brazil as well as initiatives and laws aiming at respecting, preserving and maintaining associated indigenous and local knowledge, in the context of the target 9 of the Global Strategy for Plant Conservation.

The article considers the problem of human self-identification in the modern world. The relevance of the study is due to the process of human self-alienation, the loss of the person’s rootedness in his own foundational content stemming from the human nature itself. The specificity of philosophical reflection on human being is shown. The leading approach to the study of this problem is the ascent from the abstract to the concrete, which makes it possible to comprehend human being and the phenomena of time, finitude, and corporeality associated with it as phenomena that identify the truly human principle in us and manifest the ontological meaning itself. The dialectical method and hermeneutic analysis of the texts of contemporary researchers considering the problems of the philosophical bases of the human personality in the modern world are also used in this study. The article analyzes the status of the personality in the modern technogenic world, in which the uncontrolled stream of simulations and imitations, which include the human being becoming alienated, puts on the brink not only a person’s presence in the world, but the world itself as a “native home” of human life. The analysis shows that the possibility of human self-identification in the world is possible only due to the fact that it forms and preserves the human principle in us and is the manifestation of its being. The special role of conscious, sane and responsible action in this process is shown.

The article deals with the ontological aspects of the consolidation of social being. As a fundamental reproduction mechanism, there is a phenomenon of meaning. The meaning produces, transmits the practice of connectivity and the unity of co-existence both at the individual and social levels. It is a connection, involvement that continues in the nature, quality, stability of human relations with the outside world. This connection gives the status of reality, the truth of human existence. In its ontological significance, reality as materiality, conformity, is only in experience. Thereby it is revealed that the social and individual being reality is in the space of experience that a human acquires in social interaction. «Significance of experience» forms a connection with reality, which acts as an ontological basis of meaning and grows out of its metaphysical nature. Thus, it fills the meaning itself, makes a true, real human being. The meaning connects, transforms and gives perspective to social relations. It is noted that the basis of meaning is its ontological characteristic, that is, a phenomenon arising from the real life relationships of an individual with the outside world. The nature of the meaning, which is an integral, consolidating, is determined by its transcendence. The meaning is always in the objective world. In other words, human does not choose and does not invent meaning, on the contrary, by selfrealization, it forms its connection with the world – its life meaning. Therefore, human existence requires direction to someone (something) other than herself. This metaphysical connection of being and meaning ensures the connection of human co-existence. So the true life meaning is always outside the human self, and therefore requires unity with other people. This logic reveals the phenomenon of comprehension as an integral being element, its symbolic component. Because of this, the main task of human is to go beyond the limits of their own selfishness, to feel their connection with the surrounding world. In this perspective, the meaning phenomenon is revealed in the space of sacral transformation, the personality birth. The more human overcomes the power of selfishness in themselves, the more he reveals the uniqueness of the surrounding world, the more he improves, realizes himself, acquires understanding of his own personality. In other words, self-realization itself does not foresee a direction. When in the human creativity field there is no orientation towards another human, when he «creatеs» for himself, a human must be prepared to be disappointed. Such «creativity» is empty, unclaimed, since it is devoid of its main content – love, that is, meaning. In other words, self-realization in itself should not and can not be the goal of human life. It is the result of the life meaning realization that is achieved only in the harmonious human connection with the outside world, only in productive relations with others. Therefore, self-realization is only a side effect of the man’s release beyond his own self. Consequently, meaningful life is not concentrated on its own «I», but is connected internally and externally with the lives of others. Moreover, this life is not only connected but it is also integral, since the nature of human relationship with the surrounding reality is a projection of the attitude towards himself. Thus, the analysis of the consolidation mechanisms of human existence, of its integrity, harmony, must focus in the space of the meaning problem. In other words, it is a matter of gaining a real individual experience of unity with the world. It is precisely this perspective of studying problems of integration of social and individual order that allows you to offer tools and ways to solve the issue.

Om forholdet mellem skabelse og syndefald hos Grundtvig og Luther[Grundtvig and Luther: on the Relationship Between Creation and Fall]By Anja StokholmTheologically speaking, two circumstances determine human life: on the one side, Creation and the creativity of God, on the other the Fall of Man and human sinfulness. Because God’s good creation is continuous, a positive understanding of the status and existence of natural Man is possible; but because Man is fallen and sin destroys creation, a negative perception of human life must also be acknowledged. Useful comparison may be made between the ideas of Grundtvig and Luther on this ambiguous relationship. One may ask of each: was the image of God in Man destroyed at the Fall or does the likeness of God remain a reality even in the fallen human being? Is it possible for natural Man to understand the Gospel and the Christian life? Can the understanding of the Gospels only have a negative character because it is reached from out of consciousness of sin; or can this understanding have a positive character because, sin notwithstanding, momentary experiencing of the truth of the Gospels may be granted? Are the views of Grundtvig and Luther too divergent to be reconciled?Regin Prenter maintained that their two positions closely corresponded, arguing that Grundtvig consistently developed Luther’s reformatory principles rejecting the possibility of human beings gaining justice or salvation by their own merit, and thereby also accepted that only in consciousness of the fallen condition of the world, the subverted nature of humanity, and sin, could the Gospel’s promises be received. Prenter’s harmonisation of Grundtvig and Luther, however, gives insufficient weight to the differences. Luther contends that the image of God in Man is lost, that Man is wholly sinful and unjustified; that just as inward spirit and outward flesh are discrete and cannot mix so are the justified and the unjustified states; and it follows that the unjustified human being is to be perceived a flesh alone. In so far as continuous creation, and manifestations of the positive such as the human capacity to recognise and comply with the demands of the law, are to be found in the world, these arise not from the inner resources of human beings but from the unmerited gift of God.Grundtvig too emphasises the seriousness and destructive nature of sin; but he insists that a remnant of the image of God persists in humanity - for instance in Man’s capacity to live in faith, hope and love, and to nurture the Word (that is, speech); and that its manifestation is a token of God’s continuing, and good, creation. Crucially important is Grundtvig’s conception that the image of God is located in the human heart, for this implies that goodness and the positive phenomena of creation express human life and nature in their true and proper form, and thus Grundtvig is able to identify natural human life, governed by the heart, as a positive context within which the word of the Gospel is indeed comprehensible. In differentiation, then, from Luther, Grundtvig maintains that natural Man also has a spirit and can be the agent of love and of goodness.Is this position incompatible with Luther’s doctrine on justification? Does the notion of goodness imply that Man can and must contribute to his own salvation? Grundtvig is careful to maintain that positive qualities such as love and goodness are a creation of God in Man, not an autonomous human achievement; and that the grace of God’s continuing creation in Man does not render salvation unnecessary. Man still needs the redeeming creation of Christ.Thus there are considerable differences between Grundtvig and Luther; but Grundtvig’s ideas are to be seen as a renewal and an independent continuation of Luther’s principal doctrine: that God alone can accomplish salvation. Yet acknowledgement and awareness of the differences, which arise in part through the different times and circumstances in which these independent thinkers worked, is conducive to a productive dialogue between the two.

In the period of postmodern culture, a lot of importance is attributed to mythological thinking and to the decoding of myths and current cultural signs. Therefore, the use of „talking” personal names which are perceived symbolically becomes relevant. As semiotic research points out: „For the mythological conscience it is common to see the world as a book, where cognition equals reading, which is based on the mechanisms of decoding and identification”. (Lotmans, Uspenskis 1993: 35) That means that for a better comprehension of prose, also in postmodern texts one has to pay attention to the choice of personal names, their frequency, and the presence and characteristics of cultural connotations. Bearing in mind that features of postmodern texts are the disregard of genre borders and marginalism, it can hypothetically be assumed that similar attitudes towards the use of personal names can be found in poetry. However, considering both recent studies of personal names and of poetry, it is possible to conclude that poetry pays little attention to the studies of personal names. Personal names are not very common in poetic texts, and poets use them quite precautiously (unless they link it to the tendencies within postmodernism as mentioned above). The objective of this article is to describe the functionality of personal names in latest Latvian poetry. The methodological basis of the work was obtained by studying the works of semioticians (R. Jakobson, Y. Lotman, B. Uspenskiy, Y. Levin, etc,), using the practical experience of philological text analysis (O. Nikolina, J. Kazarin), as well as by studying the attitudes of particular authors towards personal names (V. Rudnev, P. Florensky, A. Losev, G. Frege). The sources for the research for this article were anthologies of four young poetesses who were born in the 1970s and made their debut at the turn of the century, from which anthroponyms where taken for description: Inga Gaile’s „Laiks bija iemīlējies” (Time was in love, 1999) and „Kūku Marija” (Pastry Maria, 2007), Andra Menfelde’s „tranšejas dievi rok” (Gods dig trenches, 2005), Liga Rundane’s „Leluos atlaidys” (Great absolution, 2004), and Agita Draguna’s „prāts” (Mind, 2004). When analyzing the expressions of personal name in these anthologies, and thereby looking for mutual interconnections both within one anthology and from a comparative angle, a cultural sight of the generation born in the 70s (or at least of the „reading” intellectual part of that generation) could be identified. It turns out that the frequency and the uniformity/diversity of the usage of personal names can reveal tendencies of a particular trend. Clear spatial and associative semantic borders are revealed in the poetry of Agita Draguna and Liga Rundane, although it should be mentioned that personal names are very rarely used in the poetry. In contrast, the poetry of Inga Gaile and Andra Manfelde features a diversity of personal names, a tendency of appellativization, and a variety of interpretations of personal names. In the poetry of L. Rundane and A. Draguna it is possible to distinguish groups of personal names which unequivocally reveal the existence of their worlds, and mark the values of the lyrics. In the poetry of these authors two groups of personal names can be distinguished: 1) Poets: Andryvs Yurdzhs, Rainis, Oskars Seiksts (in the poetry of L. Rundane), Anthony McCann, Fjodor Tjutchev, Omar Hayam, Arseny Tarkovsky (in the poetry of A. Draguna) 2) Mythical characters: Shiva, Isida, Zuhra, Djemshid (in the poetry of A. Draguna), Virgin Mary (Jumprova Marija, in the poetry of L. Rundane). In the poetry of L. Rundane, one’s world has a Latgalian identity. In contrast, in the poetry of A. Draguna the world is more sought for, whereas one’s values seem to come from Eastern concepts of the mind and the meaning of a human life. In the poetry of I. Gaile and A. Manfelde the use of a personal name is aimed at: - marking one’s space, but unlike in the poetry of the authors mentioned above, it is full of doubts and controversies not only on the emotional level, but also regarding the values that one is looking for. Therefore personal names serve to reveal these controversies, not just to acknowledge one’s space; - a self-extinguishment of personal names and their change into simulacra, - or the process of mythologization of everyday life. It can be concluded that the limited use of personal names, of separate names, and of phrases which start with a capital letter, such as the lack of persistence in changing pronouns and generic names into the status of personal names (Miracle, You, Father of Noise, etc), proves the intensity of the perception of the mythical world, an expression paradigm common for postmodernism. (L. Rundane, A. Draguna). The relatively free and manifold use of personal names, their changes into generic names (contextual appellativization), the quest for general notions (lexical meanings), and the desire to create them (Barbie, harlequin, Aivazovsky, Lennon, Tanya, etc.) on the one hand create sumulacra, and on the other hand emphasize a mythologization of everyday life and the possibilities of its use in literary texts (through the use of figures or palimpsests).

Genetic diversity is the basis for plant breeders to develop new and improved cultivars with desirable, suited, and adaptive characteristics. Several factors such as hybridization, recombination, and mutation (Spontaneous and induced) are useful measures for providing variation in plants. However, naturally occurring mutation rate offers less for their optimum utilization. Hence induced mutation is considered to be a prime alternative other than naturally occurring variation. It has been considered a verified way of creating new variation within a crop variety which offers a possibility for the induction of desirable attributes which either can’t be expressed in nature or have been faded away during the process of evolution. Some of the mutant varieties of several crop species have led to a global contribution to crop improvement. The fate of the induced mutation largely depends on how induced mutagenesis underpins plants’ functional genome. Plant mutagenesis is had already played a significant role in crop improvement by successful enhancement of the yield, better nutritional quality, and wider adaptability. This review article is primarily centered around mutation, selection of mutant, how and when to use induced mutation, their treatment dose, and roles of mutation in Plant Breeding. Lastly, there still lies a huge potential aspect for future crop improvement through the application of induced mutation in plant species. In barley, a mutant that is resistant to mildew was 1st recorded in 1942. From the 170 diverse plant species, 3222 mutant varieties are evolved in 60 countries across the world officially. That release of varieties is possible due to the extensive use of induced mutation for 50 years in plant breeding activities all over the world. The modification of the nucleotides sequence of the genetic material of an organism, virus, extrachromosomal DNA is called a mutation. Mutagen is the agent causing mutation. There is extensive use of mutants in different subjects such as genetics, plant breeding, and plant physiology. Hugo deVries coined the term ‘mutation’ in 1901 to show sudden alteration in character considered to be heritable. Hence transmittable to the offspring while an agent causing mutation is called a mutagen. Mutation can occur naturally (spontaneous mutation) or by different agents such as chemical mutagen, ultraviolet light, x-rays, gamma rays, and so on (induced mutation). Mutagenesis is defined as the process in which the genetic information of an organism changed in a stable manner resulted in mutation.

Martin Amis’s novels are known for their representation of the dilemma of human beings in facing the problems of their age. Problems that may lead them to the status of crisis and expose them to sever psychological pain. This paper deals with issues related to identity and the traumatic conditions of the characters in two of Martin Amis's outstanding novels which are Money and London Fields.  Using a descriptive analytic approach, I will be highlighting how these characters pass through a status of crisis while living in an era of material idolization and greed that results in death of love and human noble emotions which consequently lead them to the verge of apocalypses. Although the setting of these novels are United Kingdom (UK) and the United States of America (USA), the author wants to present the case as an international problem that may affect human life in different places of the world. Through a harsh language and a realistic manifestation, Amis is disclosing the true face of modernity which apparently is very attractive but deep inside is full of atrocities and disaster. I will also indicate how some of the main characters overcome the challenges they face and are able to find out their lost identities after paying high prices both emotionally and psychologically.

Education is an important factor in human life. According to Ki Hajar Dewantara, education is a civilizing process that a business gives high values ??to the new generation in a society that is not only maintenance but also with a view to promote and develop the culture of the nobility toward human life. Education is a human investment that can be used now and in the future. One other important factor in supporting human life in addition to education, which is technology. In this globalization era, technology has touched every joint of human life. The combination of these two factors will be a new innovation in the world of education. The innovation has been implemented by Raharja College, namely the use of the method iLearning (Integrated Learning) in the learning process. Where such learning has been online based. ILearning method consists of TPI (Ten Pillars of IT iLearning). Rinfo is one of the ten pillars, where it became an official email used by the whole community’s in Raharja College to communicate with each other. Rinfo is Gmail, which is adapted from the Google platform with typical raharja.info as its domain. This Rinfo is a medium of communication, as well as a tool to support the learning process in Raharja College. Because in addition to integrated with TPi, this Rinfo was connected also support with other learning tools, such as Docs, Drive, Sites, and other supporting tools.

Cruel and inhumane acts that harm human life and health, as well as humiliate the dignity, are prohibited in most countries of the world, and Russia is no exception in this issue. The article presents an analysis of the institution of responsibility for torture in the Russian Federation. The author comes to the conclusion that the current criminal law of Russia superficially and fragmentally regulates liability for torture, in connection with which the author formulated the proposals to define such act as an independent crime. In the frame of modern globalization, the world community pays special attention to the protection of human rights, in connection with which large-scale international standards have been created a long time ago. The Universal Declaration of Human Rights and other international acts enshrine prohibitions of cruel and inhumane acts that harm human life and health, as well as degrade the dignity.Considering the historical experience of the past, these standards focus on the prohibition of any kind of torture, regardless of the purpose of their implementation.
