How to relaunch Programa 100%?

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Management from the NOVA – School of Business and EconomicsThis Work Project’s main goal is to relaunch Programa 100%, a program by Unilever Food Solutions Portugal (UFS) in partnership with the Portuguese ministry of Education that aims at providing children with healthier, more diverse and higher quality meals in public schools canteens that try to reduce the high number of obese children in Portugal. Besides, the initiative also tries to revitalize a low profitable market for UFS. This initiative has been active for almost 2 years and has not been giving the expected return to the company, so in this Work Project recommendations and conclusions are presented in order for the main strategic objective of this work project to be met: reach the breakeven point of Programa 100% in 2013. The major recommendation that is made is the addition of a new target (private schools)

Análise do efeito de filetes de adesivo na resistência estática de juntas adesivas tubulares

A procura de otimização na construção de equipamentos e estruturas tem vindo a gerar o surgimento de novos materiais, assim como novos processos de construção e de ligação. As juntas adesivas tubulares (JAT) são uma solução e possibilitam a construção de estruturas de forma mais simples, económica, leve e até resistente. Assim surge a necessidade de estudar várias variáveis que melhorem o desempenho e construção das JAT. Esta dissertação visa estudar a influência da aplicação de filetes de adesivo, com diferentes ângulos (), nas extremidades de ligação das JAT. São também considerados dois comprimentos de sobreposição (L0) de diferentes (L0=20 mm e L0=40 mm). De forma a abranger uma ampla gama de adesivos foram considerados três adesivos de características diferentes: Araldite® AV138, que se trata de um adesivo epóxido frágil, Araldite® 2015, que também é um adesivo epóxido, mas apresenta uma ductilidade moderada, e SikaForce® 7752, que se trata de um adesivo de poliuretano dúctil. Para o estudo paramétrico numérico foram utilizados modelos de dano coesivo (MDC). Inicialmente, esta técnica foi validada com resultados experimentais obtidos em trabalhos anteriores. O trabalho numérico consistiu numa análise elástica de tensões da camada de adesivo e previsão de resistência, por MDC, em função dos parâmetros geométricos e materiais referidos. Foi também realizado um estudo sobre a variável dano. Este estudo permitiu analisar a influência das alterações geométricas consoante os diferentes tipos de adesivos, possibilitando a verificação de qual a geometria que melhor se enquadra a cada tipo de adesivo. A conjugação de parâmetros que apresentou uma resistência maior, residiu no Araldite® AV138, com =7,5° e L0=40 mm.The search for optimization in the construction of equipment and structures has been generating the appearance of new materials, as well as new construction and joining processes. Tubular adhesive joints (TAJ) are a solution and make it possible to build structures in a simpler, more economical, light and even resistant manner. Thus, there is a need to study several variables that improve TAJ performance and construction. This thesis aims to study the influence of the application of adhesive fillets, with different angles, at the TAJ bonding ends. Two different overlap lengths (L0) are also considered (L0=20 mm and L0=40 mm). In order to cover a wide range of adhesives, three adhesives of different characteristics were considered: Araldite® AV138, which is a brittle epoxy adhesive, Araldite® 2015, which is also an epoxy adhesive, but has a moderate ductility and SikaForce® 7752, which it is a ductile polyurethane adhesive. For the numerical parametric study, cohesive zone models (CZM) were used. Initially, this technique was validated with experimental results obtained in previous works. The numerical work consisted of an elastic stress analysis in the adhesive layer and strength prediction, by CZM, according to the referred geometric and material parameters. A study was also conducted on the variable damage. This study made it possible to analyse the influence of geometric changes depending on the different types of adhesives, enabling the verification of which geometry best fits each type of adhesive. The combination of parameters that showed a higher resistance, resided in Araldite® AV138, with =7,5° e L0=40 mm

Scare Tactics

It is the purpose of this document to describe the design and development processes of Scare Tactics. The game will be discussed in further detail as it relates to several areas, such as market analysis, development process, game design, technical design, and each team members’ individual area of background research. The research areas include asymmetrical game design, level design, game engine architecture, real-time graphics, user interface design, networking and artificial intelligence. As part of the team’s market analysis, other games featuring asymmetric gameplay are discussed. The games described in this section serve as inspirations for asymmetric game design. Some of these games implement mechanics that the team seeks to emulate and expand upon in Scare Tactics. As part of the team’s development process, several concepts were prototyped over the course of two months. During that process the team adopted an Agile methodology in order to assist with scheduling, communication and resource management. Eventually, the team chose to expand upon the prototype that became the basis of Scare Tactics. Game design and technical design occur concurrently in the development of Scare Tactics. Designers conduct discussions where themes, settings, and mechanics are conceived and documented. Mechanics are prototyped in Unity and eventually ported to a proprietary engine developed by our team. Throughout the course of development, each team member has had to own an area of design or development. This has led to individual research performed in several areas, which will be discussed further in this document

Effects of disturbance area on fouling communities from a tropical environment: Guanabara Bay, Rio de Janeiro, Brazil

Em comunidades incrustantes marinhas, o espaço livre no substrato é um dos principais recursos limitantes para o estabelecimento de novos organismos. Assim sendo, distúrbios físicos que removam biomassa se mostram importantes agentes para a estruturação e dinâmica dessas comunidades. A extensão do distúrbio é uma característica que parece afetar os padrões de recolonização, e desta forma altera a diversidade de espécies. O objetivo deste trabalho foi analisar os efeitos de áreas crescentes de distúrbio em comunidades incrustantes. Para tal, comunidades macrobentônicas incrustantes foram previamente desenvolvidas por 6 meses na Baía de Guanabara (22°52'S, 043°08'W), recebendo uma única vez distúrbios circulares, aleatoriamente posicionados, com áreas crescentes (7 níveis, de 0 a 75% da cobertura removida, 10 réplicas por nível). Amostragens quinzenais foram realizadas após o distúrbio, de modo a acompanhar os padrões de desenvolvimento das comunidades. Na primeira amostragem observou-se que índices máximos de diversidade foram obtidos nas comunidades que receberam níveis intermediários de distúrbio. No entanto, no decorrer do tempo este perfil deu lugar a um pico de diversidade nas comunidades que sofreram os maiores níveis de distúrbio. Notou-se também um incremento contínuo da riqueza e diversidade ao longo do tempo até a 7ª amostragem (110 dias após os distúrbios), com subseqüente redução a partir deste momento. Tais padrões parecem corroborar a Hipótese do Distúrbio Intermediário, embora em médio prazo o perfil da comunidade mude drasticamente, revelando que perturbações físicas representam de fato um importante fator na estruturação de comunidades marinhas de substrato consolidado da Baía de Guanabara, além de realçar a importância de estudos de maior duração na avaliação dos impactos de distúrbios em comunidades marinhas.In marine fouling communities, free space is one of the key limiting resources for settlement of new organisms. In this way, removing biomass through physical disturbances would play an important role in the structure and dynamics of these communities. The disturbance size seems to be a characteristic that influences recolonization patterns, thus affecting species diversity. The aim of this study was to analyze the effects of growing disturbance areas on fouling communities. Fouling panels were allowed to develop for 6 mo. at Guanabara Bay (22°52'S, 043°08'W) prior to a single application of randomly positioned, circular physical disturbances of growing areas (7 levels, from 0 to 75% removed cover, 10 replicates per treatment). Samples were taken fortnightly after the disturbance event, so as to follow the development patterns of the community afterward. At the first sampling the diversity showed maximum indices in communities to which intermediary disturbance levels were applied. However, this profile changed later to a diversity peak in communities with higher disturbance levels. It also showed a continuous increase in richness and diversity through time until the 7th sample (110 days after the disturbance event), with subsequent decrease. Such patterns seem to corroborate the Intermediate Disturbance Hypothesis, despite the drastic profile change with time, revealing that disturbance is indeed an important factor structuring hard bottom communities at Guanabara Bay, and highlighting the importance of longer term studies of disturbance impacts in marine communities

Prevalence of treponema Spp. in endodontic retreatment-resistant periapical lesions

This study investigated the presence of the Treponema species in longstanding endodontic retreatment-resistant lesions of teeth with apical periodontitis, the association of this species with clinical/radiographic features, and the association among the different target species. Microbial samples of apical lesions were collected from twenty-five adult patients referred to endodontic surgery after unsuccessful root canal retreatment. Nested-PCR and conventional PCR were used for Treponema detection. Twenty-three periradicular tissue samples showed detectable levels of bacterial DNA. Treponema species were detected in 28% (7/25) of the cases. The most frequently detected species were T. socranskii (6/25), followed by T. maltophilum (3/25), T. amylovorum (3/25), T. lecithinolyticum (3/25), T. denticola (3/25), T. pectinovorum (2/25) and T. medium (2/25). T. vicentii was not detected in any sample. Positive statistical association was found between T. socranskii and T. denticola, and between T. maltophilum and T. lecithinolyticum. No association was detected between the presence of any target microorganism and the clinical or radiographic features. Treponema spp. are present, in a low percentage, in longstanding apical lesions from teeth with endodontic retreatment failure291CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPES302575/2009-0sem informaçã

Shorter delay to treatment by integrated diagnostic services and NGO-provided support among breast cancer patients in two Brazilian referral centres

Background: The diagnosis of breast cancer requires a complicated series of diagnostic exams. The present study addressed the delay of patients who used publicly and privately financed diagnostic services. Non-governmental organizations (NGOs) donated diagnostic mammograms and biopsies.Design and Methods: Data from 304 patients were obtained from two Brazilian referral centres. In one referral centre (FAP), diagnostic mammography, clinic-histopathological exam and immunohistochemistry were outsourced, whereas in the other centre (HNL), these services were integrated. Cox regression, Kaplan-Meier analysis and non-parametric tests were used to compare variables and time intervals.Results: If diagnostic mammography was financed privately and covered by private health insurance, the likelihood of a delay of >90 days between the first medical visit and the initiation of treatment decreased 2.15-fold (95%CI: 1.06- 4.36; p=0.033) and 4.44-fold (95%CI: 1.58-12.46; p=0.004), respectively. If the clinic-histopathological exam was outsourced (FAP) and publicly or privately financed, the median time between diagnostic mammography and the diagnostic result was 53 and 65 days in the integrated (HNL) and outsourced public system, compared to 29 days in the outsourced private system (p<0.050). The median time between the first medical visit and the diagnostic results of patients who were supported by NGOs, who financed their diagnostic services privately, and who used exclusively public diagnostic services was, respectively, 28.0, 48.5 and 77.5 days (p<0.050).Conclusion: Patients who used privately financed health services had shorter delays. Compared to outsourcing, the integration of the publicly financed clinic- histopathological exam diminished the delay. The support of patients by NGOs accelerated patient flow
