Use of biotechnology in agriculture has become beneficial for many farmers. However, growing of genetically modified crops has it's own specifics. Paper describes and evaluates specifics of use of biotechnologies in agriculture in the Czech Republic.

Plantas transgênicas que expressam toxinas de Bacillus thuringiensis Berliner (Bt) têm sido amplamente utilizadas para o controle de Spodoptera frugiperda (J. E. Smith) no Brasil. Entretanto, a evolução da resistência é um dos maiores entraves para a continuidade do uso desta tecnologia. Para subsidiar programas de Manejo da Resistência de Insetos (MRI), foram conduzidos estudos para o aprimoramento dos programas de manejo da resistência de S. frugiperda a tecnologias Bt. Foram realizadas estudos para determinar a dominância funcional da resistência de S. frugiperda a tecnologias Bt mediante a avaliação da sobrevivência de larvas neonatas provenientes das linhagens de S. frugiperda resistentes ao milho Herculex® que expressa a proteína Cry1F (HX-R), ao milho YieldGard VT PRO™ que expressa as proteínas Cry1A.105 e Cry2Ab2 (VT-R), ao milho PowerCore™ que expressa as proteínas Cry1A.105, Cry2Ab2 e Cry1F (PW-R), e ao milho Agrisure Viptera™ que expressa a proteína Vip3Aa20 (Vip-R), além da linhagem suscetível (Sus) e de suas respectivas linhagens heterozigotas em diversas tecnologias de milho e algodão Bt. Posteriormente, um método prático para o monitoramento fenotípico da suscetibilidade a diferentes tecnologias de milho e algodão Bt foi testado a partir da avaliação da sobrevivência de larvas neonatas em folhas de plantas Bt em populações de S. frugiperda provenientes dos Estados do Rio Grande do Sul, Paraná, São Paulo, Goiás e Bahia na safra agrícola 2014/15. E por último, a estimativa da frequência de alelos de resistência de S. frugiperda a Vip3Aa20 foi validada pelo método de F1 screen. Em geral, observou-se alta mortalidade dos heterozigotos nas tecnologias Bt testadas, comprovando que a resistência de S. frugiperda a proteínas Bt é funcionalmente recessiva o que suporta a estratégia de refúgio em programas de MRI. Verificou-se também que linhagens resistentes a eventos que expressam proteínas Cry não sobrevivem em tecnologias que expressam proteína Vip. No monitoramento prático da suscetibilidade a tecnologias Bt, sobrevivência larval superior a 70% foi observada para populações de campo do Paraná, Goiás e Bahia no milho Herculex®. Em tecnologias de milho PowerCore™ e YieldGard VT PRO™ houve sobrevivência larval variando de 1,1 a 17,9%. Em contraste, não houve sobreviventes em tecnologias de milho Viptera™. Em algodão WideStrike® que expressa as proteínas Cry1Ac e Cry1F, sobrevivência acima de 41% foi observada para populações de campo de S. frugiperda. A sobrevivência larval em Bollgard II® que expressa as proteínas Cry1Ac e Cry2Ab2 variou de 14 a 40%. No algodão TwinLink® que expressa as proteínas Cry1Ab e Cry2Ae, a sobrevivência larval das populações foi menor que 20%. O método de F1 screen foi eficiente na detecção de alelos de resistência a Vip3Aa20 em populações de S. frugiperda provenientes de diferentes regiões produtoras de milho no Brasil na safra 2014/2015. De 263 isofamílias testadas, foram detectadas três isofamílias positivas oriundas do Paraná, Mato Grosso e Goiás. A frequência de resistência estimada a Vip3Aa20 variou de 0,0140 a 0,0367 nas populações avaliadas, sendo que a frequência total foi de 0,0076. Neste estudo, fornecemos informações para refinar as estratégias de MRI, além de introduzir novas técnicas para monitorar a resistência de S. frugiperda a tecnologias Bt no Brasil. / Transgenic plants expressing toxins from Bacillus thuringiensis Berliner (Bt) have been widely used to the control of Spodoptera frugiperda (J. E. Smith) in Brazil. However, the resistance evolution is one of the major threats to the continuous use of this technology. To subsidize Insect Resistance Management (IRM), studies were conducted to improve S. frugiperda resistance management programs to Bt technologies. Studies to determine functional dominance of resistance of S. frugiperda to Bt technologies were conducted by evaluating neonate larval survival of S. frugiperda strains resistant to Herculex® maize expressing Cry1F protein (HX-R), to YieldGard VT PRO™ maize expressing Cry1A.105 and Cry2Ab2 proteins (VT-R), to PowerCore™ maize expressing Cry1A.105, Cry2Ab2 and Cry1F proteins (PW-R) and to Agrisure Viptera™ maize expressing Vip3Aa20 protein (Vip- R), in addition to susceptible strain (Sus) and the respective heterozygous strains in several Bt maize and cotton technologies cultivated in Brazil. Then, a practical method for phenotypic resistance monitoring of several Bt maize and cotton were tested, based on neonate larval survival on Bt leaf tissue in S. frugiperda populations collected from Rio Grande do Sul, Paraná, São Paulo, Goiás and Bahia States. Finally, the F1 screen method was validated to estimate the frequency of Vip3Aa20 resistance alleles in S. frugiperda. In general, high mortality of heterozygous individuals was observed on Bt technologies, confirming that resistance of S. frugiperda to Bt proteins is functionally recessive and supporting the importance of refuge areas in IRM programs. No larval survival on Vip expressing maize was found with strains of S. frugiperda resistant to maize expressing Cry toxins. In the practical resistance monitoring, more than 70% of larval survival in field populations of S. frugiperda from Paraná, Goiás and Bahia was detected in Herculex® maize. Larval survival on PowerCore™ and YieldGard VT PRO™ maize technologies ranged from 1.1 to 17.9%. In contrast, no larval survival of field populations was observed on Viptera™ maize technologies. On WideStrike® cotton, more than 41% larval survival was observed in field populations of S. frugiperda. The larval survival was on Bollgard II® ranged from 14 to 40%. In TwinLink® the larval survival was lower than 20%. The F1 screen method was efficient in detecting Vip3Aa20 resistance alleles in field populations of S. frugiperda. From a total of 263 isofamily lines tested, three positive isofamily lines from Paraná, Mato Grosso and Goiás were found. The frequency of Vip3Aa20 resistance alleles ranged from 0.0140 to 0.0367, with overall frequency of 0.0076. In this study, we provide valuable information to improve IRM strategies and propose new methods to monitor resistance of S. frugiperda to Bt technologies in Brazil.

This study considers the nature of the sacramental knowledge that was taught in the sixteenth-century catechisms of Martin Luther, Andreas Osiander, Peter Canisius, the Heidelberg Catechism, and the Catechism of the Council of Trent. Focusing on the sacraments of baptism, penance, and communion, this thesis seeks to present two principal arguments that are rooted in the indisputable fact that the catechisms were intended for a lay audience. Firstly, the knowledge imparted in sacramental instruction was too limited to delineate effectively along confessional lines, thereby raising questions about the extent to which catechisms can be viewed as tools by which to create fixed confessional identities. The second argument is that catechisms should be seen as facilitators of concord rather than division. The avoidance of complex sacramental doctrine suggests that catechisms were intended to help the laity live together. This does not suggest that there was an attempt to merge together doctrinal beliefs: each of the catechisms taught the elements of a Catholic, Lutheran, or Reformed faith. Moreover, the German catechists were fiercely devoted to their respective confessions, as evidenced by their broader publications. However, in providing religious edification for the laity, the heat was taken out of these theological divisions.

Tendo em vista que a produção dessa proteína pelo vegetal geneticamente modificado pode influenciar a capacidade da planta em alocar fungos endofíticos, o objetivo do presente estudo foi investigar as possíveis alterações na composição de fungos endofíticos associados ao algodoeiro transgênico (Bt) em comparação ao não-transgênico (não-Bt). Desse modo, coletas foram realizadas nos estádios de desenvolvimento da planta. Em cada coleta foram selecionadas amostras de folhas, caules, raízes, flores e sementes de algodoeiro Bt e não-Bt, cultivados simultaneamente. Foram isolados 23 taxa de fungos endofíticos pertencentes aos grupos Zygomycota, Ascomycota, Coelomycetes, Hyphomycetes e Blastomycetes. E 17 gêneros foram encontrados: Acremonium, Cladosporium, Colletotrichum, Curvularia, Fusarium, Glomerella, Guignardia, Lecanicillium, igrospora, Pestalotiopsis, Phoma, Phomopsis, Rhizopus, Rhodotorula, Talaromyces, Tritirachium e Xylaria. As espécies mais frequentes de fungos de acordo com o órgão vegetal foram Phomopsis archeri em folhas e caules, Phoma destructiva em raízes, igrospora sphaerica em flores e Curvularia lunata var. aeria em sementes. A abundância e diversidade de fungos endofíticos associados ao algodoeiro Bt e ao não-Bt aumentam com o envelhecimento da planta, porém não houve diferença significativa entre a composição de fungos endofíticos associados aos dois tipos de algodoeiro, indicando que a expressão da proteína Cry1Ac não afeta a capacidade do algodoeiro em alocar os fungos endofíticos e que os efeitos detectados relacionados à composição da comunidade fúngica estão associados à idade e órgão da planta. A ocorrência de fungos endofíticos em sementes de algodoeiro sugere que há transmissão vertical desses microrganismos entre as plantas de uma geração para a outra. Dos fungos endofíticos obtidos, quarenta isolados foram avaliados quanto à produção qualitativa das enzimas hidrolíticas extracelulares lipase, protease e amilase. E o melhor resultado foi apresentado por isolados de Cladosporium cladosporioides obtidos de raiz de algodoeiro Bt e do não-Bt, que apresentaram um índice enzimático alto para duas das três enzimas testadas, sendo um microrganismo promissor a ser usado em diferentes setores da indústria biotecnológica

This thesis aims to contribute to Western theology by exploring plurality as well as unity within Christianity. By looking at the history of orthodoxy as a narrative construction of identity, I argue that Christian identity is not based on doxa, dogma, or practises. Instead, I suggest that Christian identity should be rooted primarily as a practise in the experience of and participation with God through the living Christ. I propose that ecumenical unity is not ecclesial or doxalogical but rather practical because unity is achieved when groups act together and participate in each other without ceasing to be different. I explore in my first chapter the philosophical concepts (time and narrative) which form the basis of identity. I introduce the thoughts of G. Deleuze and P. Ricœur separately before bringing them together in a dialogue. The dialogue develops the concepts of time and narrative into a general theory for constructing identity. I analyse identity in the second chapter by reading historical reactions to I. Kant's conception of a permanent identity because Kant is a central focus in contemporary philosophical thought on identity. Inspired by the dialogue between Deleuze and Ricœur introduced previously, I construct a new approach to identity. My concept of identity can be applied equally to individuals and groups, however I primarily follow group identity in my thesis. My third chapter applies this theory of identity to the discussion of the concept of orthodoxy. I present a model for interpreting orthodoxy in terms of group identity, then I trace the history of orthodoxy in three general periods: the early Church, the Reformation era, and our contemporary period. I show that concerns with theological truth in questions of orthodoxy were often politicised and used to establish an authority to control Christian identity. During the Reformations, reforms were treated as questions of authority and at times resulted in exclusion rather than reform. Political moves subsequently created multiple authorities which I suggest reveal the contingency of authority. Since the nineteenth century, groups approached Christian unity without addressing the implications of authority's contingency. In my fourth chapter, I pursue the question of ecumenical unity by interpreting authorities as created and embedded in particular contexts which render impossible a single, universal authority. In contrast to a singular definition of the Church, I argue that Pauline images of the body of Christ shape Christian identity as polydox. My model of relating differences within unity reveals the extent to which many theological 'controversies' still are politicised. Finally, I argue that the ecumenical dialogue overlaps with inter-religious and 'secular' dialogues, both of which are necessary for the Church's work on identity as organic unity.

The Name of God has formed a crucial element of Jewish thought throughout its history, from the Biblical text, through the rabbinic and kabbalistic writings and into the modern age when the topic has still been a focal point for Jewish philosophers. The purpose of this study is to examine the texts of Judaism, especially those within the mystical tradition, pertaining to the Name of God, and to offer a philosophical analysis of these as a means of understanding the metaphysical role of the name generally, in terms of its relationship with identity. While the materials are historical, the aim is a speculative re/construction of a systematic philosophical approach to naming from these materials. Beginning with the formation of rabbinic Judaism in Late Antiquity, I will progress through the development of the motif into the Medieval Kabbalah, where the Name reaches its grandest and most systematic statement – and the one which has most helped to form the ideas of Jewish philosophers in the 20th Century. This will highlight certain metaphysical ideas which have developed within Judaism from the Biblical sources, and which present a direct challenge to the paradigms of western philosophy. Thus a grander subtext is a criticism of the Greek metaphysics of being which the west has inherited, and which Jewish philosophers often subject to challenges of varying subtlety; it is these philosophers who often place a peculiar emphasis on the personal name, and this emphasis seems to depend on the historical influence of the Jewish metaphysical tradition of the Name of God.

This thesis examines Thomas Aquinas' concept of human freedom in the context of his treatment of God's knowledge of future contingents. Much has been written about Aquinas' attempt to solve the problem of how humans can act freely if God knows all future things, but little of that work comments on a major underlying assumption in his treatment of the problem - namely, the concept of human freedom presupposed. This thesis therefore seeks to establish the nature of the freedom that Aquinas was assuming in the important discussions of God's knowledge of future contingents. Chapter 1 sets out Aquinas' statement of the problem and his solution to it, that since God is outside time, he knows things not as future but as 'present'; and knowing x as 'present' imposes no necessity on x itself. Some criticism of Aquinas' solution is reviewed. It is noted that although Aquinas' approach seems to imply a concept of freedom which includes the possibility of doing otherwise than one does, other interpretations are possible. It is noted also that modern commentators hold differing views on what Aquinas' concept of freedom is. Chapter 2 examines the link between contingency and freedom and makes the point that, for Aquinas, contingency in human behaviour seems to arise from the peculiarly human way of bringing things about i.e. by voluntary action. As a preliminary to looking at his analysis of voluntary action, Aquinas' distinction between 'human acts' and 'acts of man' is noted and a further distinction drawn between 'simply' and 'fully' voluntary acts. It is concluded that the nature of freedom will be found in Aquinas' description of human, or fully voluntary, acts.
