Thesis (MEng)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Numerous problems with product quality and time-to-market launches can be traced back to the management of the product lifecycle. This research assignment provides insight into how an integrated value proposition design framework can address these issues by shifting the focus of product lifecycle management from being product-centric to being customer-centric. This framework combines tools, methods and processes from a variety of disciplines such as Systems Engineering, Marketing, Project Management, and Financial Management. The application of the framework during the product lifecycle management process is that of a planning and communication tool to ensure integration between multifunctional teams to increase customer value proposition quality and decrease product time to market. This research assignment was implemented in a new product development case study within a leading Telecommunications company in South Africa. / AFRIKAANSE OPSOMMING: Die bestuur van ‘n produk se lewensiklus veroorsaak verskeie probleme wat gepaard gaan met die kwaliteit van produkte en die verlengde tydperk wat dit neem om produkte aan die mark bekend te stel.

Dans le contexte du changement global, la diminution de la disponibilité en oxygène (hypoxie) combinée à la hausse de la température sont deux phénomènes particulièrement présents dans les eaux côtières vers lesquelles les larves de poissons peuvent dériver à la fin de leur développement. Il est admis que les régulations mises en oeuvre par les organismes pour faire face à leur environnement au cours des premières étapes de leur vie peuvent avoir des conséquences sur leur trajectoire de vie ultérieure (plasticité développementale). Ainsi, l'objectif principal de cette thèse était d’évaluer si des conditions d'oxygénation (40% et 100% de saturation) combinées à des conditions thermiques (15 et 20 °C) au stade larvaire, pouvaient avoir des impacts durables sur la physiologie des futurs juvéniles de bar (Dicentrarchus labrax). Nos résultats ont révélé que les retards de croissance associés à la plus basse température et à l’hypoxie au stade larvaire induisent une croissance compensatrice. De plus, les analyses des réserves hépatiques en glycogène et en lipides ont révélé que le métabolisme des juvéniles pourrait être affecté par les conditions environnementales au stade larvaire. Par ailleurs, nos données indiquent que la capacité d'extraction de l'oxygène a été affectée chez des juvéniles en raison de déformations operculaires causées par l’exposition précoce à l'hypoxie. Enfin, l'exposition précoce à l'hypoxie induit une sur-expression à long terme de gènes de l'hémoglobine de juvéniles replacés en situation d’hypoxie. Globalement, nos résultats contribuent à faire avancer les connaissances sur la façon dont les poissons marins font face aux changements climatiques actuels. / In the context of global change, decrease in oxygen availability (hypoxia) combined with rising water temperature are especially prevalent in coastal regions, towards which marine fish larvae may drift at the end of their development. It is well admitted that the physiological regulations implemented by organisms to cope with their environment during the early life stages of life can cause profound consequences in their subsequent life-history trajectory (developmental plasticity). Therefore, the main objective of this thesis was to investigate whether ecologically relevant conditions of oxygenation (40% and 100% air saturation) combined with thermic conditions (15 and 20 °C), occurring at the last stages of larval development of European sea bass (Dicentrarchus labrax) larvae, could have long-lasting impacts on juvenile physiology. Our data showed that growth depression resulting from low temperature and hypoxic conditions at larval stage induced a subsequent compensatory growth. Moreover, our analyses of hepatic glycogen and lipid stores revealed that metabolic features of juvenile could be affected by early exposure to oxygen and temperature conditions. Furthermore, our data revealed that oxygen extraction capacity was affected due to opercular deformities caused by early exposure to hypoxia. Finally, when seabass juveniles, that have been exposed to hypoxia at larval stage, were under chronic hypoxic condition they show a long-term up-regulation of hemoglobin genes. Overall, our findings contribute to make predictions of how the marine fish communities could be altered by current climate change.

By deciphering the codes present in the glycan structure, lectins are attracting increasing interest in biotechnology. The most studied group of carbohydrate-binding proteins consists of lectins purified from species of the Leguminosae family. Among the studies of the lectins from Leguminosae. many are focused on members of the Papilionoideae subfamily, while investigations of lectins of the other two subfamilies, Caesalpinioideae and Mimosoideae, are scarce. Even within the subfamily Papilionoideae, the vast majority of studies focus on lectins from Phaseoleae and Vicieae tribes, while the other tribes of this subfamily are still poorly explored. In this context, this work describes the structural and biological characterization of two new lectins purified from seeds of Parkia biglobosa (Mimosoideae subfamily, tribe Parkiae) and Vatairea guianensis Aublet (subfamily Papilionoideae, tribe Dalbergieae). P. biglobosa seeds (subfamily Mimosoidae) possess mannose/glucose-specific lectin (PBL) that was purified by affinity chromatography on a Sephadex G-100 column. PBL is composed by a single nonglycosylated polypeptide chain of three tandemly arranged jacalin-related domains and showed important antinociceptive activity associated to the inhibition of inflammatory process. PBL was crystallized and the data produced in the X-ray diffraction experiments will enable the future resolution three-dimensional structure of this protein. With respect to the N-acetyl-D-galactosamine/D-galactose specific lectin present in the V. guianensis seeds (VGL) was demonstrated that this protein presents high similarity in primary structure to other lectins from evolutionarily related plants, such as VML and lectins belonging to the Sophoreae tribe. VGL exhibits vasorelaxant activity in contracted rat aortas, an effect that is strictly dependent on the endothelium and involves NO and the lectin domain. / Lectinas são proteínas que contém pelo menos um domínio não catalítico que se liga reversivelmente a mono ou oligossacarídeos específicos. Por serem capazes de “decifrar os glicocódigos” codificados na estrutura dos glicoconjugados, as lectinas são moléculas que possuem um grande potencial biotecnológico e despertam um grande interesse científico. As Lectinas de Leguminosas representam o grupo mais bem estudado, contudo a maioria dos estudos de lectinas de leguminosas tem envolvido membros da subfamília Papilionoideae, enquanto que investigações de lectinas de outras duas subfamílias, Caesalpinoideae e Mimosoideae, são escassas. Mesmo dentro da subfamília Papilionoideae, a grande maioria dos estudos com lectinas se concentram em membros da tribo Phaseoleae, prinicpalmente das subtribos Diocleinae e Vicieae, enquanto que as outras tribos desta subfamília ainda são pouco exploradas. Neste contexto, o presente trabalho descreve a caracterização estrutural e biológica das de duas novas lectinas purificadas de sementes de Parkia biglobosa (Subfamília Mimosoideae, tribo Parkiae) e Vatairea guianensis Aublet (Subfamília Papilionoideae, tribo Dalbergieae). Sementes de P. biglobosa possuem uma lectina (PBL) específica para manose/glicose que foi eficientemente purificada por cromatografia de afinidade em gel de Sephadex G-100. PBL é composta por uma cadeia polipeptídica única, não glicosilada e composta por três domínios relacionados a jacalina organizados em sequência. A lectina exibe atividade antiinflamatória que está associada à inibição da migração de leucócitos e uma atividade antiniciceptiva que pode estar associada à inibição da dor inflamatória. PBL foi cristalizada e os dados produzidos nos experimentos de difração do cristal por raios X possibilitarão a futura resolução da estrutura tridimensional desta proteína. Com relação a lectina específica para N-acetil-D-galactosamina/D-galactose presente nas sementes de V. guianensis (VGL) foi evidenciado que esta exibe similaridade de estrutura primária com outras lectinas isoladas de espécies de plantas taxonomicamente relacionadas, tais como lectinas isoladas da tribo Sophoreae e a lectina VML, com a qual VGL compartilha o mesmo processamento pós- traducional. Além disso, ficou evidente que VGL exibe um efeito vasorrelaxante in vitro em aortas de ratos, sendo que este efeito é dependente da presença de endotélio, envolve a participação do óxido nítrico e é mediado pelo sítio de ligação a carboidratos da lectina.

The research presented by this dissertation is linked to the Research Line of Education and Arts, part of the Graduation Program in Education of the Federal University of Santa Maria, and had the main goal of comprehending the interfaces between the consolidation of a double bass school and professor Milton Romay Masciadri. In a broader view, it also has been pursued to know and spread the professor Masciadri‟s practices in the course of more than 30 years of teaching and performance with the double bass at the state of Rio Grande do Sul; to highlight some of his pedagogical and professional strategies; to contribute for the composition of the history of musical instruments teaching in Brazil; and to approximate the educational studies about teachers to the music education and instrument teaching universe. The Teacher‟s Identitary Process, theorized by NÓVOA (1992; 1995), the biographical method of FERRAROTTI (2014), and studies about conservatorial music teaching by KINGSBURY (1988), NETTL (1995), VASCONCELOS (2002) and BURWELL (2013) are significant examples of references hereby approached. The inquiry has been developed from (auto)biographical research references (NÓVOA; FINGER, 2014; BOLÍVAR, 2002; ABRAHÃO, 2004; FERRAROTTI, 2014; DOSSE, 2009) as well as from narrative inquiry studies (STAUFFER; BARRETT, 2009; CLANDININ, 2006; LOURO; TEIXEIRA; RAPÔSO, 2014), based on the Thematic Oral History methodology (MEIHY, 2005). From a scope of six semi structured interviews, the narratives of family members and ex-students of professor Masciadri had provided the necessary subsidy for an investigation about interfaces between accessions, actions and self-awareness (NÓVOA, 1992; 1995) along with the conservatorial system of double bass teaching, and the social, political and educational contexts in issue. As results we can list a deepened understanding of the intricate bonds among identitary elements of the instrument teacher‟s self, of the one-to-one pedagogy on the conservatorial music teaching, and of the hereditary consolidation of an instrument school. The conclusions that had emerged from reflections about and from narrative data point out to the contemporaneity of the educational phenomenon of musical instrument teaching, likewise to the applicability of the present assignments to the double bass teaching today. / A pesquisa apresentada nessa dissertação está vinculada à Linha de Pesquisa Educação e Artes LP4, do Programa de Pós-Graduação em Educação da Universidade Federal de Santa Maria, e teve como objetivo central compreender as interfaces entre a consolidação de uma escola de contrabaixo e a pessoa do professor Milton Romay Masciadri. De forma mais ampla, buscou-se também conhecer e divulgar as práticas do professor Masciadri no percurso de mais de 30 anos de ensino e performance contrabaixística no Rio Grande do Sul, destacar algumas de suas estratégias pedagógicas e profissionais, contribuir para a escrita da história do ensino de instrumentos no Brasil, e aproximar os estudos educacionais sobre professores ao universo do ensino de música e de instrumentos musicais. O Processo Identitário do Professor, teorizado por NÓVOA (1992; 1995), o método biográfico de FERRAROTTI (2014), e os estudos sobre ensino conservatorial de Música de KINGSBURY (1988), NETTL (1995), VASCONCELOS (2002) e BURWELL (2013) são exemplos significativos dos referenciais abordados nesse texto. A presente pesquisa desenvolveu-se a partir de referenciais da pesquisa (auto)biográfica (NÓVOA; FINGER, 2014; BOLÍVAR, 2002; ABRAHÃO, 2004; FERRAROTTI, 2014; DOSSE, 2009) e narrativa (STAUFFER; BARRETT, 2009; CLANDININ, 2006; LOURO; TEIXEIRA; RAPÔSO, 2014), com base na metodologia de História Oral Temática (MEIHY, 2005). A partir de um escopo de seis entrevistas semiestruturadas, as narrativas de familiares e ex-alunos do professor Masciadri forneceram os subsídios necessários à investigação acerca das interfaces existentes entre as adesões, ações e autoconsciência (NÓVOA, 1992; 1995) com o sistema conservatorial de ensino de contrabaixo e os contextos sociais, políticos e educacionais em questão. Como resultados, podemos destacar um entendimento aprofundado das intrincadas ligações entre elementos identitários da pessoa do professor de instrumento, da pedagogia de-um-para-um no ensino conservatorial de música, e do fenômeno da consolidação hereditária de uma escola de instrumento. As conclusões que emergiram da reflexão sobre e a partir dos dados narrativos apontam para a atualidade do fenômeno educativo do ensino de instrumento musical, bem como para a aplicabilidade desses apontamentos para o ensino de contrabaixo hoje.

O estudo tem por objetivo geral discutir a abordagem idiomática empregada pelo compositor na escrita das partituras do contrabaixo na grade orquestral, para, a partir daí, propor a tese de que tais excertos possam ter relevância considerável para o estudo técnico-musical do instrumentista, no que se defende a pertinência de sua adoção por intérpretes, professores e estudantes de contrabaixo. A metodologia de pesquisa inclui extensa revisão de literatura, com visita a autores do século 18 aos dias atuais, seguida de identificação de equivalências idiomáticas no repertório orquestral tradicional, contextualização das influências na escrita para o contrabaixo de Villa-Lobos e concluindo, por fim, com a proposição de uma seleção de excertos para a prática pedagógica. A tese é desenvolvida em três capítulos centrais. O primeiro trata da revisão de literatura sobre estudos de excertos orquestrais para contrabaixo e traça um panorama atual de sua aplicação em instituições locais, pondo em discussão, particularmente, a escassez desses materiais no âmbito da produção orquestral brasileira. O segundo capítulo aborda as influências na escritura das linhas de contrabaixo de Villa-Lobos, com descrição de aspectos idiomáticos na escrita do compositor para o contrabaixo em obras orquestrais, ilustrados com exemplos musicais de sua linguagem composicional extraídos mais extensamente da integral de suas Sinfonias e de dois títulos seus em específico, o Choros nº 10 e a Bachianas nº 9. O terceiro capítulo apresenta uma seleção de excertos das obras destacadas, com ênfase em passagens relevantes para o estudo técnico e musical do instrumentista aqui organizadas por tipo de idiomatismo, quando também se expõem os critérios utilizados para a seleção dos excertos. A análise musical dos materiais demonstra que Villa-Lobos construiu uma escrita elaborada e idiomática para o contrabaixo, conferindo ao instrumento um tratamento de franco respeito à sua natureza grave, ao seu potencial melódico e à sua função de apoio rítmico e harmônico. Conclui-se que, além de propor novas sonoridades para o instrumento, as partituras de contrabaixo de Villa-Lobos constituem um material fundamental de estudo, coleção essa que merece figurar nas listas de excertos orquestrais destinados à preparação e profissionalização do contrabaixista, sobretudo no Brasil. / The context and the specificities of the Villa-Lobos’ treatment to the double bass in his orchestral works are the main object of the investigation hereby presented. The main goal is to discuss the idiomatic approach to the double bass on Villa-Lobos’ orchestral works as a way to present the thesis that the excerpts of such orchestral works are relevant to the technique musical study of the performer, as well as localizing and indicating its pertinence to double bass performers, professors and students. The methodology chosen was the review of the literature followed by an identification of idiomatic equivalences from the traditional orchestral repertoire, the contextualization of Villa-Lobos’ influences on its double bass writing and the selection of excerpts. The thesis is organized in three chapters, besides the introduction, conclusion and appendixes. The first chapter presents the review of the literature on orchestral excerpts for the double bass where today state of the art in Brazilians institutions is presented. The discussion is centered in the lack of material addressed to the studies of Brasilian orchestral works. The second chapter addresses the influences Villa-Lobos received while writing his double bass parts. Here idiomatic aspects of the composers writing for the instrument are described as well as a selection of works that better illustrate such writing and his symphonies, the Choros 10 and the Bachianas 9 are emphasized. The third chapter presents a excerpts selection for the double bass extracted from the works mentioned on chapter two, with emphasis on passages relevant for the technical study of the performer organized by type of idiomatism. The criteria for the selection of excerpts are also presented. At the end of this work it is possible to state that the composer had an elaborated and idiomatic writing for the double bass treating it with respect for its low range nature, its melodic potential, and its function as a rhythmic and harmonic support instrument in Villa-Lobos orchestral works. Villa-Lobos not only proposed new sonorities for the instrument but his bass parts also offer a material that deserves to be included in lists of orchestral excerpts addressed to preparatory studies for the double bassist professionalization, particularly in Brazil.

The behavior of this cichlid, which attacks lures, is especially exciting for anglers. The middle Negro River has become one of the most popular areas of sport fishing of the world, where the largest peacock bass can be found. The importance of catch-and-release fishing as an sustainable fishing strategy has been shown to directly help conserve peacock bass fish stocks in the region. In this study, peacock bass mortality was evaluated in relation to catch-and-release fishing, comparing two types of artificial lures: the jig and a traditional middle-water type. Fish, samples were collected in January/February and October/November of 2012 in the Unini River, a right margin tributary of the Negro River, in the municipal region of Barcelos in Amazonas State. A total of 191 peacock bass were caught, 90 by jig lure and the rest by the middle-water lure. Both fish groups were submitted to experimental confinement during a period of three days. In both groups, 30 fish were confined individually and 60 confined collectively. Additionally, 11 fish from the second group had radio transmitters attached to be used in telemetry. The mortality rate was calculated for each type of lure and type of confinement. No mortality was encountered for the group caught with a jig beat lure. In comparison, the middle-water lure showed a mortality rate of 1.66% for the collective confinement and 18.18% for the monitoring involving telemetry. For both types of lures, no mortality was observed for fish confined individually. The data was plotted using a Kruskal-Wallis variance analysis that showed values of X2 (1.179) = 0,502 and p= 0,478 for confined environments. The same test show values of X2 (1.179) = 1,005 e p= 0,316 for the different lures. The results indicated that neither confinement type or lure type had a significantly negative impact on the peacock bass mortality rate from the catch-and-release fishery, demonstrating that catchand- release fishing has a very small impact on peacock bass mortality. Therefore, this type of recreational fishing is beneficial as a strategy to help conserve peacock bass fish stocksfishery / A expansão da pesca amadora no Brasil teve inicio na década de 90 e tem alcançado os rios de água preta na região Amazônica, principalmente no médio Rio Negro onde são encontrados os grandes tucunarés (Cichla spp.). Com o acentuado crescimento desta atividade na região, a prática do pesque-solte vem sendo proposta como um procedimento sustentável na pesca esportiva dos tucunarés da região. Contudo, em face das dúvidas acerca da eficácia desta modalidade de pesca, avaliamos o efeito do pesque-solte sobre a sobrevivência do tucunaré, comparando dois tipos de iscas artificiais o jig e a meia-água. Foram realizados dois ensaios nos períodos de janeiro/fevereiro e outubro/novembro de 2012 no rio Unini, afluente da margem direita do rio Negro (Barcelos-AM). Em total foram capturados 191 tucunarés: 90 por iscas jig e os demais por iscas de meiaágua. Ambos os grupos de peixes foram submetidos a experimentos de confinamento por um período de 3 dias. Do primeiro grupo, 30 peixes foram confinados individualmente e 60 coletivamente. No segundo grupo, 30 foram confinados individualmente e 60 coletivamente. Adicionalmente, 11 peixes deste grupo foram marcados com transmissores de rádio para monitoramento por telemetria. A taxa de mortalidade foi calculada através do percentual dos indivíduos mortos para cada tipo de isca e ambiente de confinamento. Não houve mortalidade para o grupo de tucunaré capturado com jig. Por outro lado, a isca de meia-água apresentou taxa de mortalidade de 1,66% para o confinamento coletivo e de 18,18% para os monitorados por telemetria, não havendo, portanto mortes de indivíduos confinados individualmente. Estes dados foram analisados por meio de uma análise de variância Kruskal-Wallis, onde apresentaram valores de X2 (1.179) = 0,502 e p= 0,478 para os ambientes de confinamentos. O mesmo teste apresentou valores de X2 (1.179) = 1,005 e p= 0,316 para as iscas utilizadas. Dessa forma, os resultados indicam que ambos, o tipo de ambiente e o tipo de isca, não apresentaram influencia significativa sobre a taxa de mortalidade dos tucunarés na prática do pesque-solte. Estes resultados mostram que a prática desta modalidade de pesca amadora, resulta em baixa taxa de mortalidade para os tucunarés. Sendo assim o pesque-solte se mostra uma atividade que não prejudica a sustentabilidade dos estoques pesqueiros de tucunaré.
