A presente tese investiga as relações entre leitura, material de leitura e leitor, focalizando especificamente a revista Seleções do Reader’s Digest e seus leitores. O estudo objetiva investigar tais relações, de modo a entender a trama discursiva de situações e condições sob as quais se estabelecem normas e condutas que produzem práticas e experiências ligadas à leitura. Para tanto, a investigação foi dividida em dois eixos: o primeiro consistiu na análise de 152 exemplares, predominantemente das décadas de 40 a 70 da revista de grande circulação nacional e de origem editorial estadunidense Seleções do Reader’s Digest, e o segundo se debruçou sobre entrevistas com doze leitores da referida publicação. O aporte teórico-metodológico da pesquisa situa-se no campo dos Estudos Culturais em Educação, articulados aos estudos sobre leitura e leitores. O trabalho está estruturado com base nos seguintes autores: Roger Chartier, Miguel de Certeau, Leonor Arfuch, Rosa Silveira, Michel Foucault, Stuart Hall, Jorge Larrosa, Emmanuel Fraisse, Jean-Claude Pompougnac, Martine Poulain, Zigmunt Bauman, dentre outros. O estudo entende a leitura enquanto experiência cotidiana, compreendendo-a como sendo aquela efetuada com regularidade, estando imersa nas suas várias dimensões e implicada no social, no cultural, no político e no econômico. As narrativas produzidas através das entrevistas dessa pesquisa possibilitaram sua circunscrição em histórias pessoais, que ajustadas à sua dimensão singular são reconhecidas como histórias de leitura. Ao problematizar as relações entre discursos, comportamentos, situações, ambientes e materiais de leitura – e, em especial da Seleções (1940 a 1970), emergiram representações que puderam integrar dois tópicos analíticos: o primeiro, “Leitores e leituras” e o segundo, “Textos e tramas”. No primeiro estabeleceram-se determinados perfis, que foram denominados como identidades leitoras, identificados a partir de experiências cotidianas de leitura. Já o segundo articula outras experiências cotidianas que, assim como a leitura, estão relacionadas com lazer, entretenimento, emoções, aprendizado, senso crítico etc. Tais experiências aparecem marcadas pela escuta do rádio – em especial, as radionovelas – e a televisão. Outras mídias ainda, próprias da contemporaneidade, como a internet e suas redes sociais, também apareceram nas narrativas dos entrevistados. As conclusões do estudo apontam para alguns entendimentos sobre possíveis relações entre Seleções e a leitura que os leitores faziam dela, quais sejam: o prazer que a leitura provoca; o aprendizado da/com a leitura; a variedade de suportes de leitura; a variedade de modos, gestos e espaços de leitura; a leitura como um “lugar” de memória levando à produção de histórias de leitura e “leituras” e sua relação com consumo. Por fim, conforme alguns cenários apresentados pelos depoentes, possuir uma biblioteca, mesmo que seja com revistas – algumas encadernadas, parece aliar-se a boas práticas de leitura com hábitos diários, que buscam sempre entendimento e atualização. Tais aspectos, dentre outros, podem ser tomados como indícios de algumas das possíveis materialidades de representação de leitura na contemporaneidade. / This thesis investigates the relationship between reading, reading material and the reader, focusing specifically on the magazine Reader's Digest and its readers. The study aims to investigate these relationships in order to understand the discursive situations and conditions under which establishes norms and behaviors that produce practices and experiences related to reading. Therefore, the research was divided into two axes: the first consisted on analysis of 152 samples, predominantly from the 40s to 70 magazine widely circulated national - source publishing U.S. - Reader's Digest and the second focussed on interviews with twelve readers on that publication. The theoretical-methodological research is in the field of Cultural Studies, articulated in reading and readers studies.

The study considers reading as everyday experience, understanding it as being that performed regularly, being immersed in its various dimensions and implicated in social, the cultural, the political and economic spheres. The narratives produced through interviews of this research enabled personal stories in his constituency, which adjusted its singular dimension are recognized as reading stories. To problematize the relationship between discourses, behaviors, situations, environments and reading materials - and especially the selections (1940-1970), emerged representations that could integrate analytical two topics: first, "Readers and readings," and second. "Texts and plots." In the first certain profiles were stabilisched which were called as readers identities, identified from daily experiences of reading. The second articulates other everyday experiences, as well as reading that are related to leisure, entertainment, emotions, learning, critical sense, etc.. Such experiences are marked by listening to the radio - especially the soap operas - and television. Other contemporary media, such as the Internet and social networks also appeared in the narratives of respondents. Conclusion of studies guide some understandings about possible relationships between the magazine and readers mode which are: the pleasure that reading causes; learning from / with reading, reading the various media, modes, gestures and spaces for reading, reading as a memory "place" leading to production of reading and stories "readings" and its relation with consumption. Finally, as some scenarios presented by the interviewees, have a library, even with magazines - some bound, seems to combine best practices with daily habits of reading,wich always sick for understanding and update. These aspects can be taken as evidence for some of the possible materiality of representation in contemporary reading.

Fingerprints play an important role in biometrics and cryptography. Their creation might be based on one-way hash functions, which should usually also be collision-resistant. But users tend to draw less attention at those fingerprints - so an attacker might hand out a similar fingerprint in order to spoof identity. The main ideas for creating such 'fuzzy fingerprints' and the creation algorithm itself are discussed in this lecture. The demonstration of the tool, that produces fuzzy fingerprints shows the practical background of this technique. / Fingerabdrücke besitzen sowohl in der Kryptographie als auch in der Biometrie eine große Bedeutung. In kryptographischen Anwendungen werden diese durch Einweg-Hash-Verfahren erzeugt, die für bestimmte Anwendungen auch kollisionsresitent sein müssen. In der Praxis schenken Benutzer diesen Fingerprints weit weniger Aufmerksamkeit - oft genügt es nur hinreichend ähnliche Fingerprints auszugeben, um die Nutzer zu täuschen Die Kriterien, die dabei erfüllt sein müssen und die Erzeugung dieser "Fuzzy Fingerprints" sind Hauptbestandteil dieses Vortrags. Durch die Demonstration eines Tools im praktischen Einsatz wird dieser abgeschlossen.

Market research reports by In-Stat, Gartner, and the Swedish Post and Telecom Agency (PTS) reveal a growing worldwide demand for Voice over IP (VoIP) and smartphones. This trend is expected to continue over the coming years and there is wide scope for mobile VoIP solutions. Nevertheless, with this growth in VoIP adoption come challenges related with quality of service and security. Most consumer VoIP solution, even in PCs, analog telephony adapters, and home gateways, do not yet support media encryption and other forms of security. VoIP applications based on mobile platforms are even further behind in adopting media security due to a (mis-)perception of more limited resources. This thesis explores the alternatives and feasibility of achieving VoIP security for mobile devices in the realm of the IP Multimedia Subsystem (IMS).

[pt] O Partial Digest Problem (problema de digestão parcial), também conhecido como o Turnpike Problem, consiste na construção de um conjunto de pontos na reta real dadas as distâncias não designadas entre todos os pares de pontos. Uma variante deste problema, chamada Min Distance Superset Problem (problema de superset de distância mínimo), lida com entradas incompletas em que algumas distâncias podem estar faltando. O objetivo deste problema é encontrar um conjunto mínimo de pontos na reta real, tal que as distâncias entre cada par de pontos contenham todas as distâncias de entrada. As principais contribuições deste trabalho são duas formulações de programação matemática diferentes para o Min Distance Superset Problem: uma formulação de programação quadrática e uma formulação de programação inteira. Mostramos como aplicar um método de cálculo direto de limites de valores de variáveis através de uma relaxação Lagrangeana da formulação quadrática. Também introduzimos duas abordagens diferentes para resolver a formulação inteira, ambas baseadas em buscas binárias na cardinalidade de uma solução ótima. A primeira baseia-se num subconjunto de variáveis de decisão, na tentativa de lidar com um problema de viabilidade mais simples, e o segundo é baseado na distribuição de distâncias entre possíveis pontos disponíveis. / [en] The Partial Digest Problem, also known as the Turnpike Problem, consists of building a set of points on the real line given their unlabeled pairwise distances. A variant of this problem, named Min Distance Superset Problem, deals with incomplete input in which distances may be missing. The goal is to find a minimal set of points on the real line such that the multiset of their pairwise distances is a superset of the input. The main contributions of this work are two different mathematical programming formulations for the Min Distance Superset Problem: a quadratic programming formulation and an integer programming formulation.We show how to apply direct computation methods for variable bounds on top of a Lagrangian relaxation of the quadratic formulation. We also introduce two approaches to solve the integer programming formulation, both based on binary searches on the cardinality of an optimal solution. One is based on a subset of decision variables, in an attempt to deal with a simpler feasibility problem, and the other is based on distributing available distances between possible points.

La chute de l’URSS en 1991 a permis un renouvellement de l’historiographie occidentale sur l’histoire de ce pays durant la Guerre froide : avec l’accès à de nouvelles archives, les dimensions sociales et culturelles sont désormais prisées et la production culturelle soviétique est examinée avec un regard plus apaisé. À partir de 1967, un magazine à grand tirage soviétique fait son apparition dans plusieurs villes occidentales : le Spoutnik Digest. Son titre évoque à la fois le satellite soviétique, qui a fasciné la planète dix ans plus tôt, et le Reader’s Digest, le magazine américain agrégateur de contenu le plus vendu et le plus lu dans le monde à l’époque. La revue mensuelle, quoique similaire à son homologue américain au premier regard, contient des textes exclusivement issus d’Union soviétique et de ses journaux officiels. Comme le Reader’s Digest, le Spoutnik Digest est un objet de propagande, mais la revue offre un regard différent sur l’URSS durant la Guerre froide et sur les tensions mondiales de l’époque : dans le Spoutnik Digest, l’URSS est un pays pacifique, culturellement riche et où il fait bon vivre, la revue priorisant la valorisation du monde communiste plutôt que la critique du capitalisme et des États-Unis en particulier. En ce sens, le Spoutnik Digest se distingue clairement du Reader’s Digest, dont l’anticommunisme est agressif et omniprésent. Ce mémoire étudie le Spoutnik Digest en tant qu’objet historique et culturel entre les années 1968 et 1988. L’analyse de sa forme et de son contenu porte sur les origines de cette revue, son lectorat cible et les thèmes les plus couverts, révélant au final le message soviétique de paix et de bonne volonté politique que le magazine tentait de transmettre dans le monde durant la Guerre froide. / The fall of the Soviet Union in 1991 allowed the Cold War historiography to renew itself: social and cultural dimensions are acknowledged and the outlook on the cultural material emanating from USSR can be analyzed with more scientific objectivity and an appeased perspective. In 1967, a new magazine appeared in many Western cities: the Sputnik Digest. Its name referred both to the Soviet satellite that fascinated the world ten years earlier and the Reader’s Digest, the famous American magazine specialized in content aggregating, the most read and sold internationally at the time. The Sputnik Digest, published on a monthly basis, even though looking similar to its American counterpart at first sight, contained texts directly extracted from official Soviet newspapers in USSR. Without doubt a propaganda tool, like its American counterpart, the magazine however offered a fresh insight of the USSR during the Cold War: from the Sputnik Digest point of view, the Soviet Union was a peaceful country, culturally rich and a great place to live in. The magazine prioritized the valorisation of the USSR as opposed to criticizing the capitalist Western powers and the United States. From that standpoint it radically diverged from the aggressive ideological tone of the Reader’s Digest. This master’s thesis, through this new perspective, will study the Sputnik Digest as a historical and cultural object between the years 1968 and 1988. By looking both at its format and content, it will examine the origins of this monthly journal, its targeted readership and the most covered themes, revealing the message of Soviet peace and goodwill that the magazine tried to spread worldwide during the Cold War.

Realizaram-se dois experimentos com o objetivo de avaliar a inclusão dos ingredientes alternativos farelo de girassol e sorgo na alimentação de frangos de corte adicionando-se enzimas. Os experimentos foram divididos em três ensaios independentes, os quais corresponderam a cada fase de criação: fase inicial (1 a 21 dias), onde foram avaliadas as características de desempenho; fase de crescimento (22 a 42 dias), onde foram avaliadas as características de desempenho e as características da carcaça e fase final (43 a 49 dias), onde foram avaliadas as características de desempenho e as características da carcaça. Para cada ensaio foram utilizadas 1.280 aves de ambos os sexos avaliando-se: desempenho (consumo, ganho de peso, conversão alimentar, rendimento de carcaça e rendimento dos cortes comerciais (peito, coxa + sobrecoxa, asa e dorso)), umidade da cama, viscosidade da digesta. Os dados foram submetidos à análise de variância utilizandose o procedimento do programa SAS (Statistic Analisys System, 2001) e como teste de comparação de médias foi utilizado o Teste de Tukey. No primeiro experimento, com farelo de girassol, o delineamento foi o inteiramente casualizado, com 8 tratamentos, em esquema fatorial 2 X 2 X 2 (2 critérios de formulação aminoácidos digestíveis e totais; 2 níveis de inclusão do farelo de girassol 0% e 15%; 2 formas de utilização das enzimas: com adição e sem adição), com 4 repetições de 40 aves cada. Concluiu-se que a utilização de 15% do farelo de girassol na dieta de frangos de corte prejudicou o desempenho dos animais, não afetando o rendimento de carcaça. Nas fases de crescimento e final, o melhor desempenho foi encontrado quando as dietas foram formuladas com base em aminoácidos digestíveis e com adição de enzimas; não influenciando a umidade do material da cama, aumentando a viscosidade da digesta. No segundo experimento com sorgo utilizou-se o mesmo delineamento com 8 tratamentos, em esquema fatorial 2 X 2 X 2 (2 critérios de formulação aminoácidos digestíveis e totais; 2 níveis de substituição do milho pelo sorgo 0% e 100%; 2 formas de utilização das enzimas: com adição e sem adição), com 4 repetições de 40 aves cada. O sorgo demonstrou ser um grande substituto do milho nas dietas, pelo fato de não alterar o desempenho das aves, umidade da cama e viscosidade da digesta. Com os dois ensaios realizados concluiu-se que ingredientes alternativos são viáveis na alimentação das aves, não restringindo a criação das mesmas somente no milho e na soja. / Two experiments were conduced to evaluate the inclusion of alternative ingredients, sunflower meal and sorghum, in diet of broilers with the addition of enzymes. The experiments were divided into three independent trials, which corresponded to each phase of raising: initial phase (1 21 days), where the performance characteristics were evaluated; growing phase (22 42 days), where the performance and the carcass characteristics were evaluated, and the final phase (43 49 days), where the performance and the carcass characteristics were also evaluated. For each trial 1,280 birds of both sexes were used to evaluate: performance (feed intake, wheight gain, feed conversion, carcass yield, and comercial cuts yield (breast, thigh, thigh + thigh of any fowl, wings and back)), litter humidity, digest viscosity. The data were submitted to variance analisys using the procedure of the program SAS (Statistc Analisys System, 2001) and the Tukey Test. In the first experiment, with sunflower meal, with 8 treatments,in factorial study, 2 x 2 x 2 ( 2 formulation digestible and total aminoacids; 2 levels of sunflower meal inclusion 0% and 15%; and enzyme use: with and without addition), with 4 repetitions of 40 poultries each. It was concluded that the use of 15% of the sunflower meal in the broiler´s diet harmed the animals´ performance, not affecting the carcass yield. In the growing and final phases, the best performance was found when the diets were made based on digestible aminoacids and with addition of enzymes; not influencing the humidity of the litter, increasing the digest viscosity. In the second experiment with sorghum 8 treatments were also used, in factorial study 2 x 2 x 2 (2 formulation digestible and total aminoacids; 2 levels of substitution from the corn to the sorghum 0 % and 100%; and enzyme use: with and without addition), with 4 repetitions of 40 poultries each. The sorghum has shown to be a great replacement of the corn in the diets, because it does not alter the poultry performance, bed humidity and digest viscosity. With both experiments performed, it was concluded that the alternative ingredients are feasible in the poultry feeding, not restricting their raising solely on corn and soybeans.

In first essay, fifteen horses were used in a completely randomized design with three diets and five repetitions. Diets used were: diet without soybean oil inclusion (control); diet with inclusion of 8.5% soybean oil; diet with inclusion of 19.5% soybean oil. Trial had 34 days of duration, 30 days to adaptation of diets and four days to samples collection. Kinetics of liquid phase of digesta was estimated by LIPE? (Isolated Lignin Purified Enriched) in liquid form. The LIPE? was given only one time by oral infusion in 30th day of essay and faeces samples were collected at 2, 4, 8, 12, 16, 20, 24, 30, 36, 42, 48, 54, 60, 66, 72 and 78 hours after. Faeces characteristics were evaluate on 33th and 34th day of essay. Blood samples were taken before and at 34th day. Data were submitted to variance analysis and means compared by Student Newman-Keuls test, at 5% of significance. In secund essay, twelve horses were used in a completely randomized design with two diets and six repetitions. Diets used were: diet without soybean oil inclusion (control); diet with inclusion of 10% soybean oil. The trial had 82 days of duration, with three physical effort tests before, at 60th and at 82th day of trial. Heart frequency and body temperature were evaluation and blood samples for analyze of hematological and biochemical parameters were taken in five moments in function of physical effort tests. The first data collection, before the test, with horses at rest, and immediately after the test, and 10, 20 and 120 minutes after the physical effort tests. Data were submitted to non parametric analysis, at 5% of significance. There was a significant reduction of dry matter intake in horses fed high fat diet. Apparent digestibility of fat increased in high fat diets (P<0.05) and apparent digestibility of cellulose decrease (P>0.05) in diet with 19.5% soybean oil inclusion. Apparent digestibility of others nutrients, except crude protein, digestive kinetics and faeces characteristics were not affecting (P>0.05) in horses fed diets with soybean oil inclusion. Horses fed high fat diet increased (P<0.05) in blood level of erythrocytes, hemoglobin and triglycerides and reduction of mean corpuscular volume. Soybean oil in diets did not affect physiological, hematological and biochemical parameters along the time intake time and in function physical effort tests. High fat diets were palatable and safety without any colic or diarrheas cases. The soybean oil can used in diet for horses, reducing dry matter intake and increasing energy density of diets that is interesting to athletic horses / Objetivou-se avaliar o consumo de dietas com diferentes n?veis de inclus?o de ?leo de soja por eq?inos atletas e os efeitos na digestibilidade aparente dos nutrientes, cin?tica digestiva, caracter?sticas fecais, nos par?metros fisiol?gicos, hematol?gicos e bioqu?micos. No primeiro ensaio foram utilizados quinze eq?inos em delineamento experimental inteiramente casualizado com tr?s dietas e cinco repeti??es. As dietas utilizadas foram: dieta sem inclus?o de ?leo de soja (controle); dieta com inclus?o de 8,5% de ?leo de soja; dieta com inclus?o de 19,5% de ?leo de soja. O ensaio teve dura??o de 34 dias, sendo 30 dias de adapta??o dos eq?inos ?s dietas e quatro dias de coleta de amostras. A cin?tica da fase l?quida da digesta foi estimada pelo LIPE? (Lignina Isolada, Purificada e Enriquecida) na forma l?quida, fornecido no 30? dia de ensaio, em dose ?nica, e as amostras fecais foram coletadas nos tempos 0, 2, 4, 8, 12, 16, 20, 24, 30, 36, 42, 48, 54, 60, 66, 72 e 78 horas ap?s o fornecimento. As caracter?sticas fecais foram avaliadas no 33? e 34? dia e, as coletas das amostras sang??neas no in?cio e 34? dia do ensaio. Os resultados foram submetidos ? an?lise de vari?ncia e as m?dias comparadas pelo teste Student Newman-Keuls, com n?vel de signific?ncia de 5%. No segundo ensaio foram utilizados doze eq?inos em delineamento experimental inteiramente casualizado com duas dietas e seis repeti??es. As dietas utilizadas foram: dieta sem inclus?o de ?leo de soja (controle); dieta com inclus?o de 10% de ?leo de soja. O ensaio teve a dura??o de 82 dias, com a realiza??o de tr?s testes de esfor?o f?sico ao in?cio, 60? e 82? dia. Nesses testes foram avaliadas freq??ncia card?aca e temperatura corporal e coletadas amostras de sangue para an?lises hematol?gicas e bioqu?micas. A primeira coleta de dados ocorreu antes do teste, com os eq?inos em repouso e, imediatamente, 10, 20 e 120 minutos ap?s o t?rmino dos testes de esfor?o f?sico. Os valores m?dios dos par?metros fisiol?gicos, hematol?gicos e bioqu?micos foram submetidos ? an?lise n?o param?trica, a 5% de signific?ncia. Houve redu??o significativa no consumo de mat?ria seca das dietas com a inclus?o de ?leo de soja. O coeficiente de digestibilidade aparente do extrato et?reo aumentou (P<0,05) nas dietas hiperlipid?micas e o coeficiente de digestibilidade da celulose reduziu com a inclus?o de 19,5% de ?leo de soja. A digestibilidade dos demais nutrientes, exceto da prote?na bruta, a cin?tica da digesta no trato gastrointestinal e as caracter?sticas fecais n?o foram alteradas (P>0,05) pela inclus?o de ?leo nas dietas. Os eq?inos consumindo as dietas hiperlipid?micas apresentaram aumento (P<0,05) nos n?veis sang??neos de eritr?citos, hemoglobina e triglicer?dios e redu??o no volume corpuscular m?dio. N?o houve altera??o nos par?metros fisiol?gicos, hematol?gicos e bioqu?micos dos eq?inos alimentados com a dieta hiperlipid?mica ao longo do tempo de consumo das dietas e em fun??o dos testes de esfor?o f?sico. As dietas mostraram-se palat?veis e seguras, sem ocorr?ncia de casos de c?licas ou diarr?ias. O ?leo de soja pode ser utilizado nas dietas de eq?inos atletas visando suprir a demanda energ?tica e reduzir o consumo de mat?ria seca, desej?vel em eq?inos da modalidade esportiva Concurso Completo de Equita??o.

O trabalho teve como objetivo investigar as estrat?gias tr?ficas e a morfo-histologia do trato digest?rio desses peixes no a?ude Marechal Dutra, Acari, do semi?rido do Rio Grande do Norte, Brasil. Foram analisados 133 exemplares de tra?ra, H. malabaricus e 118 esp?cimes de cascudo, H. pusarum. As duas esp?cies estudadas apresentam diferentes n?veis de cadeia alimentar e ocupa??o espacial na coluna de ?gua do a?ude. Os resultados do trabalho est?o apresentados sob a forma de quatro artigos cient?ficos. O primeiro artigo descreve a anatomia e a histologia do trato digestivo e os h?bitos alimentares da tra?ra, H. malabaricus. O intestino da tra?ra ? curtocom um coeficiente intestinal de 0,72 ? 0,09. O ?ndice de import?ncia alimentar demonstrou que H. malabaricus se alimenta preferencialmente de material animal, sendo 72,8% de peixes e 27,2% de camar?es. A histologia do seu tubo digest?rio confirma seu h?bito alimentar carn?voro. O segundo artigo aborda um estudo pioneiro sobre os h?bitos alimentares e a caracteriza??o anat?mica e histol?gica do trato digest?rio de H. pusarum. O intestino do cascudo ? longo com um coeficiente intestinal de 10.8?0.7. O ?ndice de import?ncia alimentar demonstrou que H. pusarum se alimenta preferencialmente de material org?nico em decomposi??o (88.7%) e microalgas filamentosas e diatom?ceas (11.3%). O terceiro artigo compara os aspectos morfol?gicos do trato digest?rio de H. malabaricus e H. pusarum, relacionando-os com seu h?bito alimentar. A disposi??o dos ?rg?os digest?rios em ambas as esp?cies est? diretamente relacionada com a forma da cavidade peritoneal e o formato do corpo. O intestino curto em H. malabaricus e muito longo em H. pusarum est? relacionado com seus h?bitos alimentares. A morfologia dos tubos digest?rios de H. malabaricus e H. pusarum confirmam seus h?bitos alimentares, carn?voro e detrit?voro/herb?voro, respectivamente. O quarto artigo aborda os aspectos alimentares e reprodutivos (estrutura de comprimento e peso, rela??o peso-comprimento, tipo de crescimento, propor??o sexual) do cascudo, H. pusarum. A esp?cie apresenta crescimento alom?trico negativo, com a predomin?ncia de f?meas na popula??o amostrada.Hoplias malabaricus, que habita o ambiente pel?gico, ? considerado carn?voro, enquanto que H. pusarum, que habita o ambiente bent?nico, ? caracterizado como detrit?voro/herb?voro. Cada esp?cie estudada mostra um regime alimentar bem diferente, sem que haja competi??o tr?fica entre elas. As estruturas morfo-anat?micas do trato digest?rio refletem sua estrat?gia alimentar. / The fish, Hoplias malabaricus (Osteichthyes: Erythrinidae) and armored catfish, Hypostomus pusarum (Loricariidae) are of freshwater origin from the neotropical region, and are considered ecologically and economically of important. This work investigated the trophic strategies, the morphology and histology of the digestive tract of these fish captured from the Marechal Dutra reservoir, Acari, the semiarid region of Rio Grande do Norte, Brazil. A total of 133 individuals of H. malabaricus and 118 specimens of H. pusarum were analyzed. The two study species occupy different levels in the food chain and spatial distribution in the water column of the reservoir. The results of this study are presented in the form of four scientific papers. The first article describes the morphology and histology of the digestive tract and the feeding habits of H. malabaricus (Bloch, 1794). This fish has a short intestine, with an intestinal coefficient of 0.72 ? 0.09. The dietary importance index indicates that H. malabaricus feeds preferentially on animal matter, especially on fish (72.8%) and prawns (27.2%). The histology of its digestive tract confirms the carnivorous feeding habit. The second article discusses about the pioneering work on the feeding strategy and the characterization of anatomy and histology of the digestive tract of H. pusarum. The intestine of this fish is long, with an intestinal coefficient of 10.8?0.7. The dietary importance index indicates that H. pusarum feeds preferentially on organic matter in decomposition (88.7%) and on filamentous microalgae and diatoms (11.3%). The third article compares the morphological aspects of the digestive tract of H. malabaricus and H. pusarum, in relation to their food habits. The arrangement of the digestive organs in both species is directly related to the shape of the peritoneal cavity and the form of the body. The short intestine of H. malabaricus and the long intestine of H. pusarum are associated with their feeding habits. The morphology of the digestive tracts of H. malabaricus and H. pusarum confirm their food habits, carnivorous and detritivorous / herbivorous, respectively. The fourth article discusses the food and reproductive aspects (length and weight, length-weight relationship, type of growth and sex ratio) of H. pusarum. This species has a negatively allometric growth, with the predominance of females in the sampled population. H. malabaricus inhabits the pelagic environment and is a carnivore, while H. pusarum, lives in the benthic environment and is characterized as a detritivore/herbivore. Each species studied shows a very different diet, without trophic competition between them. The morphological and anatomical structures of the digestive tract reflect their feeding strategy.

Foram utilizados 2.970 pintos de um dia, machos e f?meas, sexados, de tr?s gen?tipos comerciais de frangos de corte (Cobb 500, Hubbard Flex e Ross 308). Foram utilizados tr?s programas nutricionais, com diferentes n?veis de amino?cidos. As aves foram distribu?das em delineamento inteiramente casualizado, em ensaio fatorial 3x3x2 (gen?tipo x ra??o x sexo), com cinco repeti??es e 33 aves/parcela. As caracter?sticas convers?o alimentar (CA), ganho em peso m?dio di?rio (GPMD) e consumo de ra??o m?dio individual (CR) peso corporal aos 35 (PC35), 42 (PC42) e 49 (PC49) dias de idade. Duas aves de cada repeti??o foram abatidas aos 35, 42 e 49 dias de idade para se avaliarem as caracter?sticas de carca?a: peso corporal ao abate, peso e rendimento da carca?a, peso e rendimento dos cortes (peito, pernas e asas). Verificou-se, no per?odo de 1 a 35 dias, intera??o entre gen?tipo x sexo para GPMD e PC35. No per?odo de 1 a 42 dias de idade, n?o houve diferen?as entre os gen?tipos para PC42, CR, GPMD ou CA. Verificou-se intera??o significativa sexo x gen?tipo para peso do peito, sendo que, entre os frangos de corte machos, as aves Cobb 500 apresentaram maior peso do peito, n?o diferindo dos machos Ross, que por sua vez n?o diferiram dos machos Hubbard. Por fim, no per?odo de 1 a 49 dias de idade, n?o houve diferen?a entre os gen?tipos para CR, GPMD ou PC49. De maneira geral, os desempenhos das aves Cobb 500, Hubbard Flex e Ross 308 n?o foram muito diferentes, sendo essas diferen?as mais presentes nas caracter?sticas de carca?a. A ra??o basal apresentou, de forma geral, melhores resultados que as ra??es com mais ou menos 10% de amino?cidos, evidenciando a boa adequa??o dos n?veis nutricionais da mesma. Os machos apresentaram-se superiores, de forma geral, para as caracter?sticas de desempenho e de carca?a, em rela??o ?s f?meas. / Disserta??o (Mestrado) ?

We used 2,970 day-old chicks, male and female, sexed, three cultivars of commercial broilers (Cobb 500, Hubbard Flex and Ross 308). We used three nutritional programs with different levels of amino acids. The broilers were distributed in a completely randomized design in factorial design 3x3x2 (genotype x diet x sex) with five replications and 33 birds / plot. The characteristics of feed conversion (FC) , average daily weight gain (ADG) and feed intake average individual (CR) body weight at 35 (PC35) , 42 (PC42) and 49 (PC49) days of age . Two birds per replicate were slaughtered at 35, 42 and 49 days of age to evaluate carcass traits: body weight at slaughter weight and carcass yield, weight and yield of cuts (breast, legs and wings). It was found in the period 1-35 days genotype x sex interaction for ADG and PC35. In the period 1-42 days of age, there were no differences among genotypes for PC42, CR, DWG or CA. There was significant interaction sex x genotype for breast weight, and between broilers, Cobb 500 had higher breast weight, did not differ from Ross 308 males, who in turn did not differ from males Hubbard. Finally, in the period 1-49 days of age, there was no difference between genotypes CR, DWG or PC49. In general, the performance of broilers Cobb 500, Hubbard Flex and Ross 308 were not very different, and these differences were more present in carcass characteristics. The basal diet showed, in general, better results than diets with more or less 10 % of amino acids, which shows the good nutritional adequacy of the same. The males showed themselves superior, overall, to the performance characteristics and carcass, compared to females.
