Esta tese analisa duas revistas de variedades, a norte americana Readers Digest e a brasileira Seleções do Readers Digest, entre os anos de 1939 e 1971. Ambas as revistas tinham como fundamento editorial a seleção e a reprodução condensada de artigos publicados em outros periódicos impressos. As publicações compõem importantes fontes de pesquisa para a percepção de elementos transnacionais entre os dois países, isto é, aquilo que era escolhido como possível para ser reproduzido em cada uma das nações, fazendo circular temáticas de maneiras distintas, a depender principalmente de contextos locais. O objetivo da análise se concentra nas relações e representações de gênero que circulavam entre Estados Unidos e Brasil, com foco no modo como a mulher é apresentada e mobilizada em diferentes situações, atentando para a forma como os periódicos, ao levarem em consideração as perspectivas locais, foram capazes de dialogar e propor papéis determinados em distintos contextos sociais e políticos. A pesquisa procura também compreender a difusão de um discurso pautado na compreensão de uma classe média universal, atentanto-se para a forma como as revistas apresentaram temas como a família, o controle de natalidade e a participação política como elementos norteadores para se atingir tal propagação. Pretende, por fim, apontar a forma como grupos subalternizados e de contestação como, por exemplo, os movimentos pelos Direitos Civis e de mulheres, foram negativamente apresentados nas páginas dos periódicos, enquanto os mesmos reforçavam tipos considerados modelares de conduta por seus editores. / This thesis analyzes two variety magazines, the North American Reader\'s Digest and the Brazilian Seleções do Reader\'s Digest, among the years of 1939 and 1971. Both magazines were based on the selection and condensed reproduction of articles published in other printed periodicals. The publications make up important sources of research for the perception of transnational elements between the two countries, that is, what was chosen as possible to be reproduced in each of the nations, circulating themes in different ways, depending mainly on local contexts. The purpose of the analysis focuses on the gender relations and representations that circulated between the United States and Brazil, focusing on the way women are presented and mobilized in different situations, paying attention to the way in which the magazines, taking into account local perspectives, were able to dialogue and propose specific roles in different social and political contexts. The research also seeks to understand the diffusion of a discourse based on the understanding of a \"universal middle class\", considering the way these magazines presented topics for instance family, birth control and political participation as guiding elements to achieve such propagation. Finally, it intends to point out how subalternized groups and of contestation, such as the movements for Civil Rights and women, were negatively presented in the pages of the periodicals, while they reinforced types considered behavioral by their editors.

Master of Science / Department of Animal Sciences and Industry / Duane L. Davis / Cell isolation method may have effects on the characteristics of the cells isolated from porcine umbilical cords. As stem cells age or approach senescence, it is hypothesized that their properties change. We expect that isolation method and age of cells will have effects on the phenotype of porcine umbilical cord (PUC) cells during in vitro expansion. We investigated the effects of three isolation methods on PUC population doublings, ability to produce colony forming units (CFU), and amount of ganglioside GD2 (GD2) expression over eleven passages. Isolation methods were explant (Exp) in which the Wharton's Jelly was removed from cords, minced and plated, enzyme digest (Dig), and stomacher assisted enzyme digestion (Stom). Cell isolates were analyzed for GD2 expression, CFU, and population doublings at early (3), middle (7), and late (11) passage. The Exp method produced greater (P<0.05) population doublings and more (P<0.05) CFU at passage 7. Explant isolates also were numerically more likely to survive to passage 11 (9/9 isolates vs 5/9 for Dig and 7/9 for Stom). In contrast, the percent cells expressing GD2 was greater (P<0.05) for Stom isolates than Exp isolates at passage 11. There were no trends for increased passage number to decreased population doubling, CFU formation, or percent GD2 positive cells. In summary, our results indicate that the Exp isolation method produced the greatest number of population doublings over 11 passages and there were minimal effects of isolation method on CFU and GD2 expression. Although Exp may be more difficult to scale up to isolate all of the PUCs in a cord, it provided greater in vitro expansion than the enzyme methods in our experiment and may provide the most cells for biotechnological and biomedical applications.

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.

The thesis "The Launch and Growth of the Reader's Digest Phenomenon on the Czech Media Market" recounts the history of the Reader's Digest Association (RDA) and its Czech affiliated company, Reader's Digest Výběr s.r.o. The first part of the thesis presents a chronological overview of the RDA's development from its founding to the present day. The second part describes and characterizes the RDA's first and best known product, Reader's Digest magazine. The magazine also engages in thematic analysis, which determines the specific themes of its content. The thesis describes the RDA's activities in the international sphere, focusing primarily on its Czech affiliate, namely on both its production and the marketing methods used by this Czech company.

A lot of information nowadays is made available through Web APIs on the Internet and without security and encryption; it is very easy for malicious users to access confidential information. The goal was to find out what different mechanisms that are available for providing a safe communication with a web API from web clients and mobile applications with little as possible impact on the performance. Learning, implementing and maintaining the mechanisms are also im- portant aspects looked at in the evaluation. Many mechanisms are available for use to secure the communication but not all are suitable for public clients. The suitable mechanisms are Digest authentication and OAuth 2.0. The chosen mechanisms were developed, tested and evaluated in regard to safety, performance impact and usabil- ity from a company perspective. The authentication and authorization mechanism, which was the most suitable, was OAuth 2.0as it has least impact on performance and better security features than the other mechanisms. / Mycket information finns numera tillgänglig via Web API:er på Internet och utan säkerhet och kryptering är det mycket lätt att illvilliga personer får tillgång till konfidentiellinformation. Målet är att ta reda på vilka olika säkerhetsmekanismer som finns tillgängliga för att tillhandahålla en säker kommunikation med ett Web API från webbklienter och mobila applikationer med så liten påverkan på prestanda. Kunskapsinhämtning, utveckling och underhållandet av lösningar är också viktiga aspeketer som tittats på vid utvärderingen av mekanismerna. Flera mekanismer finns att använda sig av för att säkra kommunkationen men de lämpliga mekanismerna för publika klienter är Digest Authentication och OAuth 2.0. De utvalda mekanismerna har utvecklats, testats, utvärderats med avseende på säkerhet, påverkan på prestanda och användbarhet utifrån ett företags perspektiv. Autentiserings- och behörighets-mekanismen som blev den utvalda var OAuth 2.0 då den har minst påverkan på prestandan och bättre säkerhets egenskaper än de andra mekanismerna.

This thesis offers an investigation into the roles of slaves and freedmen and the extent of their involvement in the Romans’ legal and literary discourse on adultery and the legislation introduced to address it – the lex Iulia de adulteriis coercendis. It also seeks to assert their place more firmly within the context of the Roman familia and explore what this means in the context of the adultery statute. This thesis reasserts the position of slaves and freedmen within the Roman familia as a whole and, more specifically, as individuals deserving and requiring of consideration within the context of the analysis of the adultery statute and other social legislation. A multi-disciplinary approach has been adopted in this thesis to address the multiple avenues apparent in the investigation. A detailed analysis of the primary extant source of the statute, found in Justinian’s Digest, was carried out to determine the extent of the inclusion of the servile and freed in adulterous relationships and how much consideration was shown to them by the legal writers, or jurists. As a corollary to this analysis, a range of literary works, from Ovid, the Elder Seneca, Quintilian, Tacitus and Suetonius, was examined to provide a counterpoint to the legal perspective on the inclusion of slaves and freedmen within adulterous relationships, and, subsequently, the familia. Re-assessing the roles of slaves and freedmen within adulterous relationships and the legislation aimed at controlling this crime also necessitates another reassessment – namely, that of the motivations behind the introduction of the statute itself. Notoriously difficult to determine, this thesis posits, in conclusion, that, rather than being an instrument of the moral indignation of the contemporary Roman population, the adultery legislation was instituted as an instrument of economic control to counter the potential dilution of the wealth of the elite of Rome by illegitimate children. Slaves and freedmen were, then, a crucial element of a deceptively complex piece of legislation typically assumed to affect and address members of the Roman elite only.

Thus, the Brazilian Agricultural Research Corporation (EMBRAPA) is selecting and improving varieties of sweet potatoes with higher levels of Beta-carotene, pro-vitamin A. The carotenoids provitamin A amount of in foods does not necessarily correspond the amount that is absorbed and metabolized by the body. For a better determination of these values and knowledge of the mechanisms of its transport and absorption, it is necessary to understand the factors that lead to the food matrix release, until the absorption and the influence on the promotion and maintenance in human health. In order to perform preliminary studies of its absorption, this study aims to determine the efficiency of micellization of Beta -carotene in orange sweet potato (Ipomoea batatas, Lam), by applying a in vitro digestion as a tool for determining the bioaccessibility, which is the first step for bioavailability determination. This approach aims to simulate the oral, gastric and intestinal stages of human. The digestion was performed with 10 g of fresh samples, homozeneided with 5% (w/w) of canola oil. The extraction was performed with acetone and petroleum ether and the micellar fraction with petroleum ether, NaCl 10% (w / v) and NaSO4 2% (w/v) and involves the use of enzymes as -amylase , pepsin, bile, pancreatin, lipase and mucin, and inorganic compounds such as KCl, KSCN, NaH2PO4, Na3PO4, NaOH, NaCl, CaCl2, HCl, NaHCO3. The physiological variations are reproduced by the heating bath shaker with orbital gyrus (37?C) and centrifugation (5000g, 45 min). Quantification and determination of the profile of carotenoids were performed by high performance liquid chromatography (HPLC) with YCM ? C30 Carotenoid S-3 4.6 x 250mm column. Quantification of total carotenoids was performed by UV-VIs. The whole procedure was performed under controlled temperature (25 ? C) and light. The Beta -carotene was present mainly with levels of 86%, 73% and 82% for access 1, 2 and 3 and after digestion, the profile of Beta -carotene has set levels of 96%, 89% and 100%, respectively. The efficiency of micellization was 23.8%, 28% and 25% for 1.2 and 3 hits, indicating Beta -carotene transfer of the food matrix to micelles, corresponding to bioaccessibility of the compound. This methodology proved to be faster and cheaper, since the in vivo studies are costly, complex and require more time. / O Brasil foi classificado pela Organiza??o Mundial da Sa?de (OMS) como ?rea de car?ncia sub-cl?nica grave de vitamina A. Assim, a Empresa Brasileira de Pesquisa Agropecu?ria (EMBRAPA) v?m selecionando e melhorando variedades de batata-doce com teores maiores de Beta-caroteno, composto pr?-vitamina A. A quantidade de caroten?ides pr?-vitamina A presentes nos alimentos n?o corresponde necessariamente ?quela quantidade absorvida e metabolizada pelo organismo. Para uma melhor determina??o destes valores e conhecimento dos mecanismos de transporte e absor??o deste composto, faz-se necess?rio, o entendimento dos fatores que levam ? sua libera??o da matriz do alimento, at? a extens?o de sua absor??o, bem como a influ?ncia na promo??o e manuten??o da sa?de humana. A fim de realizar estudos preliminares de sua absor??o, este trabalho visa determinar a efici?ncia de miceliza??o de Beta-caroteno de batata-doce de polpa alaranjada (Ipomoea batatas, Lam.), atrav?s da aplica??o de digest?o in vitro, como ferramenta de determina??o da bioacessibilidade, etapa preliminar para a determina??o da biodisponibilidade. Esta metodologia visa simular as etapas de digest?o oral, g?strica e intestinal humana. Foram pesados 10g de amostra in natura e adicionados 5% (p/p) de ?leo de canola. A extra??o do alimento foi realizada com acetona e ?ter de petr?leo e a da fra??o micelar, com ?ter de petr?leo, NaCl 10%(p/v) e NaSO4 2%(p/v) . Enzimas como: a-amilase, pepsina, bile, pancreatina, lipase e mucina, bem como compostos inorg?nicos, tais como KCl, KSCN, NaH2PO4, Na3PO4, NaOH, NaCl, CaCl2, HCl, NaHCO3. As varia??es fisiol?gicas foram reproduzidas pelo banho de aquecimento com giro orbital (37?C) e centrifuga??o (5000g;45 min). A quantifica??o e determina??o do perfil de caroten?ides foi realizada por cromatografia l?quida de alta efici?ncia (CLAE), com coluna YCM? Carotenoid C30 S-3 de 4,6 x 250mm. A quantifica??o de caroten?ides totais foi realizada por espectrofotometria UV-VIs. Todo o procedimento foi executado sob temperatura (25?C) e luz controlada. O Beta-caroteno estava presente majoritariamente, com teores de 86%, 73% e 82%, para as variedades 1, 2 e 3 e ap?s a digest?o, o perfil do Beta-caroteno passou a configurar teores de 96%, 89% e 100%, respectivamente. A efici?ncia de miceliza??o foi de 23,8%, 28% e 28,9% para as variedades 1,2 e 3, indicando a transfer?ncia do - caroteno da matriz do alimento para as micelas, correspondendo a bioacessibilidade deste composto. Esta metodologia demonstrou-se mais r?pida e mais barata, quando comparada aos estudos in vivo, que s?o mais onerosos, complexos e demandam mais tempo.
