O presente estudo tem como objetivo comparar a efic?cia dos f?rmacos ibuprofeno e a associa??o de code?na + paracetamol, no controle da sensibilidade imediata gerada pelo clareamento dent?rio de consult?rio com per?xido de hidrog?nio a 35%. M?todos: Foram selecionados aleatoriamente 60 volunt?rios e os mesmos foram divididos em 3 grupos: Placebo (PL) 400 mg (n= 20), Ibuprofeno (IB) 400 mg (n= 20) e associa??o de Code?na 30 mg + Paracetamol 500 mg (CP) (n= 20). Os volunt?rios foram submetidos a 2 sess?es de clareamento com per?xido de hidrog?nio 35% em 2 aplica??es de 20 min cada. As medica??es foram tomadas 1 hora antes do procedimento clareador em ambas as sess?es. Os valores de sensibilidade foram coletados utilizando uma escala visual anal?gica de dor. A an?lise estat?stica foi feita atrav?s do teste de ANOVA 1 Fator e p?s teste de tukey, utilizando o software Assistat?. Resultados: Houve diferen?a estatisticamente significativa entre os tratamentos (p<0,01) (m?dias: PL: 4,7; IB: 4,8 e CP: 1,0). Conclus?o: O tratamento da associa??o de code?na + paracetamol foi mais eficaz em eliminar a sensibilidade imediata gerada pelo clareamento dent?rio com per?xido de hidrog?nio 35%, com valores bem pr?ximos de zero, em compara??o as medica??es ibuprofeno e placebo. / Sensitivity is the main adverse effect caused by tooth whitening. The aim of the present study was to compare the efficacy of ibuprofen and the combination of codeine + paracetamol in the control of the immediate sensitivity generated by dental office whitening with 35% hydrogen peroxide. Methods: Sixty volunteers were randomly selected and divided into three groups: Placebo (PL) 400 mg (n = 20), Ibuprofen (IB) 400 mg (n = 20) and Codeine 30 mg + Paracetamol 500 mg (N = 20). The volunteers were submitted to 2 bleaching sessions with 35% hydrogen peroxide in 2 applications of 20 min each. Medications were taken 1 hour before the bleaching procedure in both sessions. Sensitivity values were collected using a visual analog pain scale. Statistical analysis was done using ANOVA 1 Factor and post test of tukey, using Assistat? software. Results: There was a statistically significant difference between the treatments (p <0.01) (averages: PL: 4.7, IB: 4.8 and CP: 1.0). Conclusion: The treatment of codeine + paracetamol was more effective in eliminating the immediate sensitivity generated by tooth whitening with 35% hydrogen peroxide, with values close to zero, compared to ibuprofen and placebo.

Em meio ao declínio do consumo de cigarros devido ao aumento das campanhas restritivas e a crescente consciência pública dos riscos associados à saúde dos fumantes, as indústrias de cigarros se deparam com o constante desafio de desenvolver novas tecnologias de fabricação e materiais que minimizem os efeitos da fumaça de cigarros sobre a saúde dos consumidores. O sabor e a composição da fumaça ingerida pelo fumante durante o ato de fumar dependem fundamentalmente da combinação do design do cigarro e do blend de fumo utilizado. O interesse na realização desta pesquisa foi avaliar a influência da densidade do filtro de cigarros na redução dos teores dos principais constituintes da fumaça. Para a realização do estudo, protótipos de cigarro foram fabricados em escala industrial, utilizando o mesmo blend de fumo e demais parâmetros de design do cigarro, apenas variando a especificação do denier do acetato de celulose utilizado na fabricação do filtro. O desempenho dos filtros como material filtrante da fumaça foi avaliado em termos da queda de pressão e das propriedades da fibra do cabo de acetato. E, utilizando métodos padronizados, os protótipos de cigarro foram fumados em máquina de fumar e a composição dos teores de alcatrão, nicotina e monóxido de carbono foi determinada para a avaliação da capacidade de retenção dos filtros de cigarro fabricados com diferentes densidades. Os resultados mostram que a utilização de cabos de acetato com menor denier por filamento nos filtros de cigarro apresenta grande desempenho na redução dos constituintes da fase particulada da fumaça, como o alcatrão e a nicotina, porém não apresenta efeito na redução do monóxido de carbono, substância volátil presente na fase vapor da fumaça. No entanto, cabos de acetato com menor espessura dos filamentos somente podem ser utilizados em filtros de cigarro se combinados com outros parâmetros de design de cigarro a fim de não apresentar prejuízo na aceitação do produto junto aos consumidores, devido ao aumento no esforço para a realização da tragada. / In the middle of the cigarette consumption decline caused by the increase of restrictive advertising campaigns and smokers’ health risk public awareness, tobacco industries now encounter the permanent challenge of developing materials and new manufacturing technologies to minimize cigarette smoke effects in regards to consumers’ health. The taste and formulation of the smoke absorbed in the smoking activity crucially depend on the combination between cigarette design and tobacco blend. The aim in this research was to evaluate the influence of cigarette filter density to reduce the level of smoke main constituents. In order to conduct the study, cigarette prototypes were manufactured at industrial proportion, using the same tobacco blend and respective cigarette design parameters, but only varying the denier specification of the cellulose acetate filter tow used to produce the filter. The performance of filters as smoke-filtering materials were evaluated in terms of pressure drop and filter tow fiber properties. And, according standardized methods, cigarette prototypes were smoked in smoking machines, and the composition of tar, nicotine and carbon monoxide levels was determined to evaluate the retention capacity of the cigarette filters manufactured with different densities. Results show that the use of filter tows with low denier per filament in cigarette filters increases smoke particulate phase components removal efficiency, such as tar and nicotine, but it does not present effects to reduce carbon monoxide, volatile substance that exists in the smoke vapor phase. However, filter tows with of filaments can only be used in cigarette filters if combined with other design parameters in order to avoid damage in the product acceptance by consumers due to the increase of effort in the cigarette puff.

O presente trabalho observa a iniciativa do governo federal que pretende garantir a qualidade do ensino brasileiro, através da igualdade de oportunidades e de acesso ao conhecimento por meio do Projeto Um Computador por Aluno – UCA. Tais tecnologias estão sendo disponibilizadas em fase de estudo piloto, podendo, posteriormente, atingir a totalidade de escolas regulares no país. Por outro lado, faz-se necessário observar que a Política Nacional de Educação Especial na Perspectiva da Educação Inclusiva, garante o acesso e permanência de pessoas com deficiência nos bancos regulares de ensino. Observar como ocorre o processo inclusivo de pessoas com deficiência mediadas por laptops foi o objetivo deste estudo. Caracterizando-se como uma pesquisa qualitativa, descritiva em formato de estudo de caso, este trabalho enfocou a realidade de Tiradentes-MG. Esta cidade configura-se como UCA total, ou seja, município em que todas as escolas foram contempladas nesta fase do projeto piloto. Sob o enfoque vygotskyano avaliou-se quais mudanças ocorrem nas dimensões cognitivas e sociais de pessoas com deficiência quando mediadas por laptops em contexto escolar, bem como se identificou quais movimentos inclusivos estão sendo desencadeados a partir da implementação do PROUCA, tanto nas dinâmicas de sala de aula e nas escolas quanto na gestão educacional do município. Os diferentes resultados da pesquisa apontaram que o projeto de disseminação de laptops do governo federal, balizando a ferramenta ofertada sob o conceito da homogeneidade e uniformidade tecnológica, impõe barreiras ao atendimento da diversidade em situação de inclusão sociodigital. Além disso, observamos que a prática inclusiva em Tiradentes garante a vinculação do aluno especial à rede regular de ensino, mas ainda não articula movimentos capazes de promover a efetiva participação dos sujeitos com deficiência no ambiente escolar, quer seja pela falta de acesso arquitetônico, pela restrição ao atendimento educacional especializado ou pelo escasso apoio pedagógico ao professor. / This paper analyzes the federal government initiative which aims to ensure the quality of education in Brazil through equal opportunity and access to knowledge with the One Laptop per Child Project – UCA. These technologies have become available in a pilot study phase and may subsequently reach the totality of regular schools in the country. However, it is necessary to note that the National Policy on Special Education, in the Perspective of Inclusive Education, ensures access and retention of people with disabilities in regular education classes. The objective of this study was to observe how the inclusive process of disabled people mediated by laptops occured. Characterized as a qualitative research, with a descriptive case study format, this work focused on the reality of Tiradentes-MG, which is a city considered as total UCA, that is, a municipality in which all schools were covered in this phase of the pilot project. Under the Vygotskian approach, the study assessed what changes occured in cognitive and social dimensions of people with disabilities when mediated by laptops in the school context, and it also identified which inclusive movements were triggered by the implementation of PROUCA, both in the classroom and school dynamics and in educational administration of the municipality. The different results of the research showed that the federal project of distribution of laptops imposes barriers to address diversity in a situation of sociodigital inclusion by delimiting the offered tool under the concept of technological homogeneity and uniformity. Furthermore, we observed that the inclusive practice in Tiradentes, ensures the binding of the special student to the regular school system, but it has not yet articulated movements that promote the effective participation of individuals with disabilities in the school environment, whether by lack of access Architectural, the restriction tospecialized educational services, or by the limited pedagogical support to the teacher.

Neste trabalho buscamos evidências, para o caso brasileiro, da Hipótese da Renda Permanente. Primeiro, investigamos a existência de tendências e ciclos comuns entre as séries de consumo e renda per capita. Então, usando o resultado de co-movimentos entre as variáveis decompomos cada série em tendência e ciclo, através dos modelos de componentes não observados de Harvey (1989). Por fim, usando os modelos de vetores autorregressivos, decompomos a variância dos erros de previsão, seguindo a metodologia de Blanchard e Quah (1989), com o objetivo de avaliarmos a importância relativa dos choques permanentes e transitórios para as variações do consumo. Os resultados apontam que as inovações permanentes são responsáveis pela maior parte das variações no consumo. Este resultado embora rejeite a Hipótese da Renda Permanente, indica que o consumo responde pouco a variações transitórias na renda, ou seja, os choques temporários têm pouca importância para o consumo.

This current study was elaborate in order to evaluate the information about biology of the population, more specifically about population structure, spatial distribution, and reproductive aspects of U. victoriana from mangrove of Itacuru?? / Coroa Grande located in Sepetiba Bay, RJ. Three transects were established with three areas on the right bank of the Draga river, and each area containing 10 m long and 2.25 m wide. Crabs were collected monthly during the period of November 2010 to October 2011. The animals were collected using a quadrat of 30 x 30 cm, performing three random replicates in each plot. In laboratory, the animals were separated by sex and it were taken biometric measurements such as carapace width, carapace length, abdomen width, height of the larger chelipod, length of the larger chelipod and length of the gonopod. Sediment samples were collected in three transects to determine the granulometric composition. It was collected a total of 529 individuals in the study period, of which 89 were males, 97 females non-ovigerous, 16 ovigerous females and 327 juveniles. In the population structure the frequency distribution of males and females was unimodal. The average size of the female LC was 5,64 ? 1,73 mm and 4,97 ? 1,53 mm for males. The analysis of size comparison between sexes showed that females are significantly larger (U = 23741.5, p <0.001) than males. The overall sex ratio of population was 1,94:1, predominantly males. In spatial distribution, there was a greater abundance of animals in the area 2, where the predominance of juveniles, ovigerous females and non-ovigerous females was not superior to other transects. The average size of the ovigerous females was 6.67 ? 0.60 mm, ranging from 5.38 to 7.70 mm. Mean fecundity was 424 ? 186 eggs, with a range from 211 to 886 eggs. The average size of the eggs was 0.292 ? 0.011 mm, with a width 0.27 to 0.30 mm. Recruitment occurred in April. The morphological maturity of females was estimated for the size 5.0 mm and 5.9 mm for males. It follows that the U. victoriana population from mangrove studied, showed to be stable, showing juveniles during all of the months. The distribution of U. victoriana was not influenced by temperature or granulometric, suggesting that other factors, for example, the abundance of trees or biologic factors could influence their distribution in the mangrove. The fecundity found in this population correlates with the females size, as occurs in most brachyuran. The reproductive period was seasonal, with higher frequency of ovigerous females in the months of September and October. / A esp?cie Uca victoriana von Hagen, 1987 ? um caranguejo pertencente ? fam?lia Ocypodidae, t?pico de zonas entremar?s, caracterizado por um forte dimorfismo sexual. O presente trabalho teve como objetivo obter informa??es sobre a biologia populacional, mais especificamente em rela??o ? estrutura populacional, distribui??o espacial e aspectos reprodutivos de U. victoriana do manguezal de Itacuru??/Coroa Grande localizado na Ba?a de Sepetiba, RJ. Foi estabelecido um transecto com tr?s ?reas na margem direita do rio da Draga, onde cada ?rea tinha 10 m de comprimento por 2,25 m de largura. Os caranguejos foram coletados mensalmente durante o per?odo de novembro de 2010 a outubro de 2011. Os animais foram coletados utilizando-se um quadrat de 30 x 30 cm, realizando-se tr?s r?plicas aleat?rias em cada parcela. No laborat?rio os animais foram separados por sexo e tomadas as medidas biom?tricas, como a largura da carapa?a, comprimento total, largura do abdome, comprimento do maior quel?podo, altura do maior quel?podo e comprimento do gonop?dio. Amostras do sedimento foram coletadas nas tr?s ?reas para determinar a composi??o granulom?trica. Foi coletado um total de 529 indiv?duos no per?odo de estudo, dos quais 89 eram machos, 97 f?meas n?o ov?geras, 16 f?meas ov?geras e 327 juvenis. Quanto ? estrutura populacional, a distribui??o de frequ?ncia em machos e f?meas foi unimodal. O tamanho m?dio da LC dos machos foi de 4,97 ? 1,53 mm e das f?meas de 5,64 ? 1,73 mm. A an?lise de compara??o do tamanho entre os sexos demonstrou que as f?meas s?o significativamente maiores (U= 23741,5; p< 0,001) em rela??o aos machos. A propor??o sexual da popula??o foi de 1,94:1 (M:F), com predomin?ncia de machos. Na distribui??o espacial, houve maior abund?ncia de animais na ?rea 2, onde a predomin?ncia de juvenis, f?meas ov?geras e f?meas n?o ov?geras foi superior em rela??o ?s outras ?reas. O tamanho m?dio das f?meas ov?geras foi de 6,67 ? 0,60 mm, variando de 5,38 a 7,70 mm. A fecundidade m?dia foi de 424 ? 186 ovos, com uma amplitude de 211 a 886 ovos. O tamanho m?dio dos ovos foi de 0,292 ? 0,011 mm, com uma amplitude de 0,27 a 0,30 mm. O pico de recrutamento ocorreu no m?s de abril. A maturidade morfol?gica das f?meas foi estimada para o tamanho de 5,0 mm e dos machos de 5,9 mm de LC. Conclui-se, que a popula??o de U. victoriana do manguezal estudado demonstrou ser est?vel, apresentando juvenis durante todos os meses. A distribui??o de U. victoriana n?o foi influenciada pela temperatura e granulometria, sugerindo que outros fatores como a abund?ncia de ?rvores ou fatores bi?ticos podem estar influenciando sua distribui??o neste manguezal. A fecundidade encontrada nesta popula??o se correlaciona com o tamanho das f?meas, como ocorre na maioria dos braqui?ros. O per?odo reprodutivo foi sazonal, com maior frequ?ncia de f?meas ov?geras nos meses de setembro e outubro.

Requirements prioritization is an important part of developing the right product in the right time. There are different ideas about which method is the best to use when prioritizing requirements. This thesis takes a closer look at five different methods and then put them into an controlled experiment, in order to find out which of the methods that would be the best method to use. The experiment was designed to find out which method yields the most accurate result, the method’s ability to scale up to many more requirements, what time it took to prioritize with the method, and finally how easy the method was to use. These four criteria combined will indicate which method is more suitable, i.e. be the best method, to use in prioritizing of requirements. The chosen methods are the well-known analytic hierarchy process, the computer algorithm binary search tree, and from the ideas of extreme programming come planning game. The fourth method is an old but well used method, the 100 points method. The last method is a new method, which combines planning game with the analytic hierarchy process. Analysis of the data from the experiment indicates that the planning game combined with analytic hierarchy process could be a good candidate. However, the result from the experiment clearly indicates that the binary search tree yields accurate result, is able to scale up and was the easiest method to use. For these three reasons the binary search tree clearly is the better method to use for prioritizing requirements

A combination of an original work of fiction, Alone Among Friends, and a critical discussion of masculinity in the work of Per Petterson, this dissertation joins a growing conversation in the field of Masculine Studies about the depiction of men in literature. Written in a spare and realistic style, Alone Among Friends is a novella that hopes to explore ideas of masculinity, friendship, success, and failure present in the mindset of the American Millennial generation. Takings its cues from The Sun Also Rises, Light Years, and The Salt Point, Alone Among Friends examines the destructive nature of hyper-masculinity and highlights the danger of attaching too much meaning to external validation as the measuring stick for one's self worth. Moreover, Alone Among Friends is also influenced by the themes of memory and knowing found within the work of Per Petterson. "How Memories of the Father Inform a Son's Understanding of Masculinity in the Novels of Per Petterson" discusses the ways in which Per Petterson, a Norwegian writer, has been both influenced by American notions of masculinity and also managed to incorporate European aspects of family into his work to create a unique hybrid perspective that merges the American idea of the emancipated male protagonist with the European family centered narrative. By tracing Petterson's influences, this dissertation will attempt to show how Petterson is a logical heir to such American writers as Ernest Hemingway and Richard Ford, and it will argue that, by firmly grounding his novels in the point of view of sons that study every aspect of their fathers, Petterson inhabits a space that has long been absent from both American and Norwegian literature alike. Through the examination of Out Stealing Horses and In the Wake, this dissertation focuses on the varying ways in which these direct comparisons between father and son influence the son's perception of his own success and failure as a man.

The aim of this research was to find relationships between complimentary advertising strategies and sponsored search advertisement (SSA) in order to formulate a model to maximise return on investment achieved from online sponsored search advertisements. The results obtained from statistical analyses of SSA campaign data showed that complimentary online and offline advertisement campaigns have various different correlations to impressions, click-through rates, number of pages visited, time spent visiting a website, bounce rate of visitors to the website, cost-per-click and number of new registrations per keyword search from visitors gained through SSA campaigns. In particular, online display advertisements were found to have a slight positive correlation with new registrations made by customers gained through a simultaneously running SSA campaign. Offline radio adverts were found to have a positive correlation with impressions gained for SSA campaigns, whilst at the same time showing a negative correlation with the number of pages viewed by website visitors obtained through the SSA campaign. Some negative correlations to SSA campaign performance were also found, with the time visitors spent viewing the website decreasing, their bounce rate increasing and the cost-per-clicks for the keywords in the SSA campaign also increasing during periods when offline radio adverts were active. Offline television adverts were found to have a negative correlation with impressions gained for SSA campaigns, as well as the click-through rate for the keywords in these SSA campaigns. Offline television adverts did however also show a negative correlation with the cost-per-clicks for keywords in the SSA campaigns. Finally, a graphical model was developed to illustrate these correlations found between complimentary advertisement campaigns and SSA performance metrics. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted
