Abstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior
The central aim of this work is to examine Surrealistic traces in the novel A Torre da Barbeia. In this work, the Portuguese writer Ruben A. mixes the stream of Portuguese literary tradition conceming the reflection upon nation with Surrealistic influences. Therefore, the present analysis has the objective of investigating Surrealistic traces of the novel, specially the representation of the Supematural. This study is divided into three chapters. Chapter one presents a brief historical description of Surrealism as an artistic device. Next, this chapter offers a review on the literary works by Ruben A. as well as some literary criticism about the author's production. It has been observed that Surrealistic influence is one of the most recurrent subjects as critics have highlighted, on the hand, representation of the Supematural is an almost disregarded matter. Chapter two develops an analysis of the novel in order to identify Surrealistic aspects in its construction. The third chapter approaches the topic of the depiction of the Supematural, according to different theories with regard to the Wonderful. The results point to the presence of both categories. It is through them that the verisimilar is breached and the primacy of the imagination over the prosaic, as defended by Breton and his disciples, is conveyed. As a consequence, another reality on the leveI of the text is established.
O objeto deste estudo é o rd'mance A Torre da BarbeIa (1964), do escritor português Ruben A., que alia, à tradição literária portuguesa de reflexão sobre os destinos pátrios, uma forte influência do Surrealismo. Por isso, a proposta de análise apresentada objetiva levantar traços surrealistas no romance e, dentre eles, examinar um aspecto marcante na composição da obra, a representação do sobrenatural. O trabalho divide-se em três capítulos. O primeiro realiza um breve histórico sobre o movimento surrealista. Após, apresenta-se o autor e sua produção para, então, efetuar-se a revisão da fortuna crítica da obra. Observou-se que, embora a influência surre alista seja citada recorrentemente pelos críticos, a representação do sobrenatural é aspecto pouco explorado pelos estudiosos. O segundo capítulo apresenta a análise do romance, buscando desmembrar-Ihe a estrutura e identificar determinados traços surrealistas em sua construção. Finalmente, o terceiro capítulo aborda o tópico da representação do sobrenatural através de uma revisão teórica das categorias do fantástico e do maravilhoso, seguida do exame de sua configuração no romance. Os resultados obtidos revelam que a obra apresenta ambas as categorias e que, através delas, rompe-se com o verossímil, realizando, conforme defendido por Breton e discípulos, o primado da imaginação sobre o prosaico e instaurando textualmente uma outra realidade, próxima do sonho. Tal procedimento, contudo, não conduz ao desvinculamento da realidade nacional. Ao contrário, serve como suporte para um mergulho na "essência" da nacionalidade, num processo de desmitificação do passado ao pôr em cena as forças inconscientes por trás das ações de portugueses de épocas históricas variadas.

Abstract:
Esta dissertação tem como principal objetivo a introdução à obra do designer Ruben de Freitas Martins (1929 - 1968), apreendendo a sua trajetória e algumas das principais características criativas de seu trabalho. Ele iniciou sua carreira como artista plástico, derivando-a para o design até atingir a posição de empresário do setor, engajado na divulgação da profissão no Brasil. Nessa condição, durante a década de 60 dirigiu a Forminform, considerado o primeiro escritório de design do país. Na primeira parte da dissertação, com o intuito de analisar de forma eficaz e comparativa o seu trabalho, buscamos investigar e reconstruir a trajetória de Ruben Martins, sua formação profissional e o círculo social com o qual conviveu. Para tanto, foi realizado um levantamento de dados sobre a história e o contexto do designer, incluindo a coleta de matérias jornalísticas, artigos e entrevistas realizadas com personalidades que possuem informações sobre o próprio, como João Carlos Cauduro e Karl Heinz Bergmiller, além da constante pesquisa junto ao Acervo Pessoal de Ruben Martins, recolhido pela família. Na segunda parte, encontra-se a análise detalhada de um de seus principais trabalhos, a marca criada para a Rede de Hotéis Tropical (1967), \"leitura\" esta construída a partir do rebatimento das informações levantadas na primeira parte do trabalho.
This dissertation has as main objective the introduction to the work of designer Ruben de Freitas Martins (1929 - 1968), seizing his career and some key features of his creative work. He began his career as an artist, deriving her to the design to reach the position of manager of the sector, engaged in spreading the profession in Brazil. In this condition, during the 60´s, directed the office Forminform, considered the first design office in the country. In the first part of the dissertation, in order to effectively analyze and compare their work, we investigate and reconstruct the trajectory of Ruben Martins, vocational training and social circle with whom he lived. To that end, we conducted a survey about the history and context of the designer, including collection of news stories, articles and interviews with personalities who have information about him, as João Carlos Cauduro and Karl Heinz Bergmiller, farther the constant search with the Personal Collection of Ruben Martins, picked up by family. The second part is the detailed analysis of one of his major works, the brand created for the Network of Tropical Hotels (1967), the \"reading\" is built from information gathered in the first part of the dissertation.

Abstract:
Abstract In this work, steam generation was studied using natural gas or rumen as energy sources in a slaughter plant that sacrifices 7500 cattle per month, with consumption 0.5749 kg/s of saturated steam at 624 kPa. For a slaughtered cow, 10.5 kg of rumen can be obtained after being dried outdoors; for its final disposal, the slaughter plant bears the costs of USD 7.2 per ton of rumen. In the study, exergy and exergoeconomic performances were compared by generating steam with a natural gas boiler with the steam generation with a rumen boiler. From this, combustion analysis, energy efficiency, exergy destruction, exergy efficiency, exergy destruction costs, and generating 1 kg of steam from the two boilers were evaluated. The study results showed that the generation of steam with rumen is less efficient than with natural gas since it presents the exergy destruction of 1175.9 kW and exergy efficiency of 26.83%. While the generation of steam with rumen boiler was obtained, with exergy destruction of 1419.9 kW and exergy efficiency of 23.29%. Exergy destruction cost and the cost of generating 1 kg of steam using rumen were $/h 7821 and 0.0073 $/kg, respectively. Although the generation of steam with natural gas present the exergy destruction cost of 26285 $/h and the cost of generating steam of 0.021 $/kg, this indicators are higher using natural gas as a fuel that with rumen pellets.

Abstract:
The rumen microbial communities of ruminants are thought to be the most promising biochemical source of inordinately diversified and multi-functional cellulolytic enzymes with unique functional adaptations to improve biotechnological processes. The exploitation of rumen microbial genetic variety has been limited due to a lack of effective screening culture techniques and a lack of understanding of the rumen microbial genetic diversity. This study is conducted to isolate and characterize rumen bacteria from goat rumen that have capability to produce xylanase enzyme. Serial dilutions technique is applied to isolate bacteria from goat rumen and repeated tubing of the selectively enriched microbial cultures by using the specific media for rumen bacteria. Following that, all of the isolates were underwent Methyl Red (MR) test & Voges-Proskauer (VP) test to identify organisms metabolic pathway, Triple Sugar Iron Agar (TSI) Test to determine bacterial ability to utilize sugar, Motility Indole and Urease activity test (MIU) to determine motility, Urease utilization and can produce Indole or not, Citrate utilization test to utilize citrate as carbon and energy source, Oxidase test, Catalase test to check the presence of catalytic enzyme where all isolates found promising which indicates that all five isolates are superior and capable to produce xylanase.

Full text
Abstract:
Over the past decade, one can observe a steady growth in the use of terms such as Place Branding, Nation Branding, Destination Branding and City Branding. Both in academic research and in the practical applications in large cities management and urban spaces, this new paradigm takes shape and, along with it, the need for definitions and concepts, methods and methodologies and the establishment of technical and theoretical standards. This approach was born in the Marketing field, specifically in what was called Place Marketing. In this context the Branding stood out as a development tool solutions to the need for differentiation, generation of solid images and the establishment of symbols and identity signs, in order to leverage economic benefits for countries, cities and regions. In a way, fulfilling, in the first instance, a similar role to the branding of products and services. But it was specifically in Branding corporations that were found the biggest matches to adapt this knowledge to management positions. Ashworth & Kavaratzis (2010) highlight the fact that both present multidisciplinary roots, a multiple number of strategic actors (stakeholders), high degree of intangibility and complexity of social responsibility, the multiplicity of identities and the long-term development needs are strong examples their similarities. The development and management of corporate identities, here expanded to the Branding corporations, it is a prolific field of Design. It great names of the area said their careers and built great legacy. The time of greater proficiency in the area were the 50s and 60s, dominated by modernist thought, and, coincidentally or not, exactly the time that focused efforts to assert the identity of the designer as a professional (STOLARSKI, 2006) . Nationally stand out names like Alexandre Wollner, Ruben Martins, the duo Carlos Cauduro and Ludovico Martino and Aloisio Magalhaes. In contrast, in the literature produced in the marketing field, often the role of design in this context is reduced to merely promotional measures, such as creating logos or advertising campaigns. In other words, defined as a work of low complexity and low social prägnanz. This approach comes at odds with contemporary theories of design, such as MetaDesign, Design Thinking and Design Collaborative, in which are presented motodológicos models of high relevance for the identification, analysis and solution of complex problems involving multiple elements and agents. The proposed article aims to survey the state of the art City Branding / Place Branding focused on publications produced in the disciplinary field of design. The literature review will grant that, before the above presented context, is analyzed as designers and researchers design face the contributions that the field can offer to the practice and theory of Branding places. Finally, Article yearns assess whether the pre-established hypothesis that there are possible and fruitful connections between contemporary theories of design and the City Branding, is being addressed in articles and publications area.DOI: http://dx.doi.org/10.4995/IFDP.2016.3288

Abstract:
Ruminants provide human society with high quality food from non-human-edible resources, but their emissions negatively impact the environment via greenhouse gas production. The rumen and its resident microorganisms dictate both processes. The overall goal of this project was to determine whether a causal relationship exists between the rumen microbiome and the host animal's physiology, and if so, to isolate and examine the specific determinants that enable this causality. To this end, we divided the project into three specific parts: (1) determining the feed efficiency of 200 milking cows, (2) determining whether the feed- efficiency phenotype can be transferred by transplantation and (3) isolating and examining microbial consortia that can affect the feed-efficiency phenotype by their transplantation into germ-free ruminants. We finally included 1000 dairy cow metadata in our study that revealed a global core microbiome present in the rumen whose composition and abundance predicted many of the cows’ production phenotypes, including methane emission. Certain members of the core microbiome are heritable and have strong associations to cardinal rumen metabolites and fermentation products that govern the efficiency of milk production. These heritable core microbes therefore present primary targets for rumen manipulation towards sustainable and environmentally friendly agriculture. We then went beyond examining the metagenomic content, and asked whether microbes behave differently with relation to the host efficiency state. We sampled twelve animals with two extreme efficiency phenotypes, high efficiency and low efficiency where the first represents animals that maximize energy utilization from their feed whilst the later represents animals with very low utilization of the energy from their feed. Our analysis revealed differences in two host efficiency states in terms of the microbial expression profiles both with regards to protein identities and quantities. Another aim of the proposal was the cultivation of undescribed rumen microorganisms is one of the most important tasks in rumen microbiology. Our findings from phylogenetic analysis of cultured OTUs on the lower branches of the phylogenetic tree suggest that multifactorial traits govern cultivability. Interestingly, most of the cultured OTUs belonged to the rare rumen biosphere. These cultured OTUs could not be detected in the rumen microbiome, even when we surveyed it across 38 rumen microbiome samples. These findings add another unique dimension to the complexity of the rumen microbiome and suggest that a large number of different organisms can be cultured in a single cultivation effort. In the context of the grant, the establishment of ruminant germ-free facility was possible and preliminary experiments were successful, which open up the way for direct applications of the new concepts discovered here, prior to the larger scale implementation at the agricultural level.

Abstract:
The overall objective of the whole research was to elucidate the mechanisms by which LAB silage inoculants enhance ruminant performance. The results generated will permit the development of better silage inoculants that maximize both silage preservation and animal performance. For this one-year BARD feasibility study, the objectives were to: 1. determine whether lactic acid bacteria (LAB) used in inoculants for silage can survive in rumen fluid (RF) 2.select the inoculants that survived best, and 3. test whether LAB silage inoculants produce bacteriocins-like substances. The most promising strains will be used in the next steps of the research. Silage inoculants containing LAB are used in order to improve forage preservation efficiency. In addition, silage inoculants enhance animal performance in many cases. This includes improvements in feed intake, liveweight gain and milk production in 25-40% of studies reviewed. The cause for the improvement in animal performance is not clear but appears to be other than direct effect of LAB inoculants on silage fermentation. Results from various studies suggest a possible probiotic effect. Our hypothesis is that specific LAB strains interact with rumen microorganisms which results in enhanced rumen functionality and animal performance. The first step of the research is to determine whether LAB of silage inoculants survive in RF. Silage inoculants (12 in the U.S. and 10 in Israel) were added to clarified and strained RF. Inoculation rate was 10 ⁶ (clarified RF), 10⁷ (strained RF) (in the U.S.) and 10⁷, 10⁸ CFU ml⁻¹ in Israel (strained RF). The inoculated RF was incubated for 72 and 96 h at 39°C, with and without 5 g 1⁻¹ glucose. Changes in pH, LAB numbers and fermentation products were monitored throughout the incubation period. The results indicated that LAB silage inoculants can survive in RF. The inoculants with the highest counts after 72 h incubation in rumen fluid were Lactobacillus plantarum MTD1 and a L. plantarum/P. cerevisiae mixture (USA) and Enterococcus faecium strains and Lactobacillus buchneri (Israel). Incubation of rumen fluid with silage LAB inoculants resulted in higher pH values in most cases as compared with that of un-inoculated controls. The magnitude of the effect varied among inoculants and typically was enhanced with the inoculants that survived best. This might suggest the mode of action of LAB silage inoculants in the rumen as higher pH enhances fibrolytic microorganisms in the rumen. Volatile fatty acid (VFA) concentrations in the inoculated RF tended to be lower than in the control RF after incubation. However, L. plalltarull1 MTDI resulted in the highest concentrations of VFA in the RF relative to other inoculants. The implication of this result is not as yet clear. In previous research by others, feeding silages which were inoculated with this strain consistently enhanced animal performance. These finding were recently published in Weinberg et.al.. (2003), J. of Applied Microbiology 94:1066-1071 and in Weinberg et al.. (2003), Applied Biochemistry and Biotechnology (accepted). In addition, some strains in our studies have shown bacteriocins like activity. These included Pediococcus pentosaceus, Enterococcus faecium and Lactobacillus plantarum Mill 1. These results will enable us to continue the research with the LAB strains that survived best in the rumen fluid and have the highest potential to affect the rumen environment.

Abstract:
The effect of rumen available protein amino acids and carbohydrates on microbial protein synthesis, amino acid flow and performance of high yielding dairy cows was studied. A significant relationship between the effective degradabilities of OM in feedstuffs and the in vivo ruminal OM degradation of diets of dairy cows was found. The in situ method enabled the prediction of ruminal nutrients degradability response to processing of energy and nitragenous supplements. The AA profile of the rumen undegradable protein was modified by the processing method. In a continuous culture study total N and postruminal AA flows, and bacterial efficiency, is maximal at rumen degradable levels of 65% of the CP. Responses to rumen degradable non carbohydrate (NSC) were linear up to at least 27% of DM. Higher CP flow in the abomasum was found for cows fed high ruminally degradable OM and low ruminally degradable CP diet. It appeared that in dairy cows diets, the ratio of rumen degradable OM to rumenally degradable CP should be at least 5:1 in order to maximize postruminal CP flow. The efficiency of microbial CP synthesis was higher for diets supplemented with 33% of rumen undegradable protein, with greater amounts of bacterial AA reaching the abomasum. Increase in ruminal carbohydrate availability by using high moisture corn increased proportions of propionate, postruminal nutrients flow, postruminal starch digestibility, ruminal availability of NSC, uptake of energy substrates by the mammory gland. These modifications resulted with improvement in the utilization of nonessential AA for milk protein synthesis, in higher milk protein yield. Higher postruminal NSC digestibility and higher efficiency of milk protein production were recorded in cows fed extruded corn. Increasing feeding frequency increased flow of N from the rumen to the blood, reduced diurnal variation in ruminal and ammonia, and of plasma urea and improved postruminal NSC and CIP digestibility and total tract digestibilities. Milk and constituent yield increased with more frequent feeding. In a study performed in a commercial dairy herd, changes in energy and nitrogenous substrates level suggested that increasing feeding frequency may improve dietary nitrogen utilization and may shift metabolism toward more glucogenesis. It was concluded that efficiency of milk protein yield in high producing cows might be improved by an optimization of ruminal and post-ruminal supplies of energy and nitrogenous substrates. Such an optimization can be achieved by processing of energy and nitrogenous feedstuffs, and by increasing feeding frequency. In situ data may provide means for elucidation of the optimal processing conditions.
