Dispositivos de monitorização e controlo automático de factores climáticos em museus

As redes de comunicação sem fios são uma área de grande desenvolvimento. As tecnologias progridem e criam-se novas oportunidades de implementação de novos dispositivos nesta área. Neste tipo de redes, encontram-se as redes de sensores sem fios (WSN- Wireless Sensor Networks), que são constituídas por vários dispositivos (Nós Sensores) que colaboram entre si, para recolher e encaminhar informação sobre um determinado fenómeno físico até uma estação base. A um outro nível, a preservação das obras de arte é uma preocupação fundamental de todos os Museus. Existe a necessidade de conservar ao máximo as características genuínas de cada artefacto. Para tal, torna-se essencial uma monitorização e controlo de alguns factores ambientais, que podem danificar ou alterar as características dos materiais. Essa monitorização é realizada nos museus da Madeira, mas de uma forma manual e recorrendo a aparelhos que são dispendiosos e um pouco arcaicos. Assim sendo, tornou-se necessário encontrar uma solução, para a realização dessa tarefa de uma forma automática e contínua. As WSN oferecem uma resposta para estas necessidades, surgindo assim o projecto WISE-MUSE, que visa a monitorização ambiental para a conservação de obras de arte e artigos históricos, através de redes sem fios.Portanto, este projecto de Mestrado em Telecomunicações e Redes tem como área de acção a camada física da arquitectura do sistema WISE-MUSE. Neste sentido, desenvolveu-se um conjunto de dispositivos electrónicos, para monitorização e controlo de factores climáticos no Museu de arte contemporânea do Funchal. A ligação entre dispositivos e transmissão dos dados recolhidos foi assegurada através da implementação de uma rede sem fios. Ao nível dos nós sensores construídos, os desenvolvimentos mais importantes tiveram como meta a minimização de custos, consumo energético e dimensões dos mesmos. Além dos sensores, foram desenvolvidos outros componentes da rede, nomeadamente dispositivos routers e um dispositivo que permite o controlo automático da humidade.

Geologia e recursos hídricos subterrâneos da Ilha da Madeira

Nesta tese da especialidade de Hidrogeologia, é apresentado um primeiro levantamento vulcano-estratigráfico da ilha da Madeira. Os trabalhos de campo permitiram definir, até agora, sete unidades geológicas principais, descritas da mais antiga para a mais recente: 1- Complexo Vulcânico Antigo (CA) 2- Calcários Marinhos dos Lameiros - S. Vicente (CM) 3- Depósito Conglomerático-Brechóide (CB) 4- Complexo Vulcânico Principal (CP) 5- Complexo Vulcânico S. Roque/Paul (SRP) 6- Episódios Vulcânicos Recentes (VR) 7- Depósitos de Vertente (dv), Fajãs (fj), Quebradas (q), Depósitos de Enxurrada Recentes (dr), Areias de Praia (ap), Dunas Fósseis (df), Terraços (t), e Aluviões (a) A caracterização climática da ilha da Madeira foi feita com base nos dados recolhidos em 27 pontos de observação climatológicos, dos quais 14 são estações meteorológicas e 13 são postos udométricos, o que representa uma densidade de 1 ponto de observação/27 km2. Constatou-se que a variação da precipitação com a altitude não era linear e dependia da orientação das vertentes. Efectuou-se o balanço hídrico sequencial diário, com base nos valores de precipitação média diária, registados no Paul da Serra, durante os últimos 15 anos hidrológicos. Pretendeu-se quantificar a precipitação oculta na vegetação típica da ilha da Madeira, de modo a poder avaliar a contribuição daquele tipo de precipitação para os recursos hídricos subterrâneos, e, ainda, determinar qual o potencial daquele recurso natural, como contribuição importante às fontes tradicionais de abastecimento de água à ilha. Para o efeito, procedemos a dois tipos principais de medição: medição directamente sob a vegetação de altitude da Madeira, o urzal, que se desenvolve entre os 1200 e os 1600 m de altitude, e construção de aparelhos constituídos por obstáculos artificiais, de modo a interceptarem as gotículas de água contidas no nevoeiro. Pela sua importância, os resultados obtidos justificam o desenvolvimento futuro deste estudo. A caracterização hidrodinâmica das formações da ilha da Madeira baseou-se nas observações feitas no interior das galerias e túneis em escavação, na análise dos registos de caudais de galerias e nascentes e na interpretação de ensaios de bombeamento dos furos de captação. Os dados evidenciam a grande heterogeneidade e anisotropia características do meio vulcânico. As transmissividades vão desde 11 m2/d até 25 766 m2/d. A caracterização hidrogeoquímica permitiu identificar um grupo de 5 águas termais, emergentes em falhas, no Complexo Antigo, com características muito próprias, bastante distintas das restantes, que representam, quer em quantidade, quer em volume de caudais captados, a grande maioria das águas da ilha da Madeira. O principal fenómeno mineralizador das águas é a hidrólise de minerais silicatados, verificando-se, nas águas dos furos, nas das nascentes de altitude e nas situadas próximo do litoral, o efeito da contaminação de sais de origem marinha. A partir dos dados hidrogeológicos obtidos, foi possível elaborar um modelo conceptual de funcionamento hidrogeológico para a ilha da Madeira, que, apesar de possuir alguns elementos comuns, é, no seu conjunto, diferente dos modelos conhecidos para outras ilhas vulcânicas, nomeadamente, Canárias, Reunião, Havai e Polinésia Francesa.

Estudo de soluções de monitorização automática de ribeiras para prevenção do risco de aluviões

As aluviões, também denominadas por fluxos de detritos ou enxurradas, são movimentos de vertente rápidos, que ocorrem por ação da água e são consideradas um dos fenómenos mais perigosos em regiões montanhosas, causando prejuízos por onde passam. Como forma de prevenção, mas também como forma de estudo das condições inerentes à formação destes fenómenos e do respetivo comportamento ao longo do seu percurso, deve ser atribuído um papel importante à monitorização automática dos cursos de água. Na Ilha da Madeira, a aluvião mais recente aconteceu a 20 de fevereiro de 2010, afetando os concelhos da vertente Sul, particularmente os do Funchal e Ribeira Brava. Este evento surgiu devido a uma situação meteorológica adversa, com precipitações de elevada intensidade, resultando no transporte de um elevado volume de material sólido que levou ao transbordamento das ribeiras, obstruindo completamente a baixa funchalense e outros locais. Portanto, esta dissertação surge como introdução à temática do estudo e monitorização dos fluxos de detritos na Ilha da Madeira, onde, inicialmente, foi realizada uma primeira abordagem ao fenómeno, referindo as suas causas e características, tendo sido, também, mencionadas algumas das aluviões que assolaram a ilha. Posteriormente, foram descritos alguns dos equipamentos incluídos num sistema de monitorização, com as respetivas vantagens e desvantagens, bem como a descrição de alguns sistemas existentes. Como objetivo deste trabalho, foi idealizada uma solução de monitorização automática para a bacia hidrográfica da Ribeira de Machico, tendo sido analisadas as propriedades morfológicas da bacia, seguindo-se uma descrição dos sensores utilizados e a sua localização. Por fim, como caso de estudo, foi apresentado o sistema de monitorização a ser implementado pelo LREC (Laboratório Regional de Engenharia Civil), onde foram definidos os aparelhos utilizados, bem como a respetiva localização.

Mapeando fundamentos do Constructo Neuromarketing com profissionais de empresa de publicidade

This study aims to acknowledge the domain level and influence of the neuromarketing construct. This is done considering professionals at advertising agencies in Brazil. The presence of concepts related to this new approach is very little divulged, and there are little analysis performed on this area. Thus, the research is of qualitative and exploratory nature and used as primary fonts books, articles related to marketing, neuroscience, and psychology as well as secondary fonts. A profound interview was realized aiming the main advertising agencies in Brazil. The public was composed by managers responsible for planning. A content analysis was performed afterwards. The advances related to the brain science have permitted the development of technological innovation. These go primarily towards knowledge and unconscious experiences of consumers, which are responsible for the impulse of decision making and consumer behavior. These issues are related to Neuromarketing, that in turn, uses techniques such as FMRI, PET and FDOT. These scan the consumer s brain and produces imagines on the neuron s structures and functioning. This is seen while activities such as mental tasks for the visualization of brands, images or products, watching videos and commercials are performed. It is observed that the agencies are constantly in search of new technologies and are aware of the limitations of the current research instruments. On the other hand, they are not totally familiar with concepts related to neuromarketing. In relation to the neuroimage techniques it is pointed out by the research that there is full unawareness, but some agencies seem to visualize positive impacts with the use of these techniques for the evaluation of films and in ways that permit to know the consumer better. It is also seen that neuroimage is perceived as a technique amongst others, but its application is not real, there are some barriers in the market and in the agencies itself. These barriers as well as some questioning allied to the scarce knowledge of neuromarketing, make it not possible to be put into practice in the advertising market. It is also observed that even though there is greater use of neuromarketing; there would not be any meaningful changes in functioning and structuring of these agencies. The use of the neuro-image machines should be done in research institutes and centers of big companies. Results show that the level of domain of the neuromarketing construct in the Brazilian advertising agencies is only a theoretical one. Little is known of this subject and the neurological studies and absolutely nothing of neuroimage techniques

Os efeitos das reclamações online na lealdade dos consumidores: um estudo experimental

In an environment of constant change, technological developments, market competition and more informed consumers, the search for a lasting relationship through the conquest of loyalty has become the objective of companies. However, several authors suggest that this loyalty can be affected by negative comments available on the internet. Therefore, this dissertation has as objective to examine if the complaints are available on the internet impact the loyalty to a brand of mobile phone. The research used as the basis the Expanded NCSB model suggest by Johnson et al. (2001), studying five prominent drives of loyalty: image/brand reputation, affective commitment, calculative commitment, perceived value and trust, beyond the satisfaction construct as moderator variable. The research method adopted was the experimental design which included 285 undergraduate students, with the trial which included 285 undergraduate students, with the field study of the mobile industry, specifically, the brands of cell phones. The research approach was quantitative and methods were descriptive statistics, factor analysis, cluster analysis, linear regression and non-parametric test of Wilcoxon for data analysis. Of the 16 hypothesis stemmed from the research model proposed, 12 were confirmed. The results showed that the complaint available on the internet, here represented by the available on the site Reclame Aqui, may impact consumer perceptions about brand loyalty, as well as its antecedents, being that these complaints can affect all the consumers, regardless of historical satisfaction with the brand. It also noted the positive relationship between the independent variables trust, image/brand reputation, perceived value, affective commitment and calculative commitment and the dependent variable - loyalty, even when considering the data obtained after exposure to the complaint. However, no unanimous conclusion that the relationship between these variables was strongest in the group with satisfactory experience. At the first moment of the research, the trust was the most important variable for the formation of loyalty. However, after exposure to treatment, the image/brand reputation, was more relevant. Contributions of the study, limitations and recommendations for future researches are approached in the present investigation

Estudo e desenvolvimento de um capacitor eletrolítico de nióbio

It seeks to find an alternative to the current tantalum electrolytic capacitors in the market due to its high cost. Niobium is a potential substitute, since both belong to the same group of the periodic table and because of this have many similar physical and chemical properties. Niobium has several technologically important applications, and Brazil has the largest reserves, around 96%. There are including niobium in reserves of tantalite and columbite in Rio Grande do Norte. These electrolytic capacitors have high capacitance specifies, ie they can store high energy in small volumes compared to other types of capacitors. This is the main attraction of this type of capacitor because is growing demand in the production of capacitors with capacitance specifies increasingly high, this because of the miniaturization of various devices such as GPS devices, televisions, computers, phones and many others. The production route of the capacitor was made by powder metallurgy. The initial niobium powder supplied by EEL-USP was first characterized by XRD, SEM, XRF and laser particle size, to then be sieved into three particle size, 200, 400 e 635mesh. The powders were then compacted and sintered at 1350, 1450 and 1550°C using two sintering time 30 and 60min. Sintering is one of the most important parts of the process as it affects properties as porosity and surface cleaning of the samples, which greatly affected the quality of the capacitor. The sintered samples then underwent a process of anodic oxidation, which created a thin film of niobium pentóxido over the whole porous surface of the sample, this film is the dielectric capacitor. The oxidation process variables influence the performance of the film and therefore the capacitor. The samples were characterized by electrical measurements of capacitance, loss factor, ESR, relative density, porosity and surface area. After the characterizations was made an annealing in air ate 260ºC for 60min. After this treatment were made again the electrical measurements. The particle size of powders and sintering affected the porosity and in turn the specific area of the samples. The larger de area of the capacitor, greater is the capacitance. The powder showed the highest capacitance was with the smallest particle size. Higher temperatures and times of sintering caused samples with smaller surface area, but on the other hand the cleaning surface impurities was higher for this cases. So a balance must be made between the gain that is achieved with the cleaning of impurities and the loss with the decreased in specific area. The best results were obtained for the temperature of 1450ºC/60min. The influence of annealing on the loss factor and ESR did not follow a well-defined pattern, because their values increased in some cases and decreased in others. The most interesting results due to heat treatment were with respect to capacitance, which showed an increase for all samples after treatment

Efetividade do clareamento dentário com peróxido de carbamida a 10% e avaliação dos efeitos adversos sobre o esmalte dentário

The aim of the present study was to assess the effectiveness and adverse effects on dental enamel caused by nightguard vital bleaching with 10% carbamide peroxide. This was accomplished through the interaction of researchers from different areas such as dentistry, materials engineering and physics. Fifty volunteers took part in the doubleblind randomized controlled clinical trial. They were allocated to an experimental group that used Opalescence PF 10% (OPA) and a control group that used a placebo gel (PLA). Fragments of human dental enamel from the vestibular surface of healthy premolars, extracted for orthodontic reasons, were fixed to the vestibular surface of the first upper molars of the volunteers for in situ observation. Bleaching was performed at night for 21 days. The observation periods included Baseline (BL), T0 (21 days), T30 (30 days after treatment) and T180 (180 days after treatment, only for the OPA group). Tooth color was assessed by comparing it with the Vita® scale and by the degree of satisfaction expressed by the volunteer. We also assessed adverse clinical effects, dental sensitivity and gingival bleeding. The study of adverse effects on enamel was conducted in vivo and in situ, using the DIAGNOdent® laser fluorescence device to detect mineral loss. Scanning electron microscopy (SEM) was used to check for superficial morphological alterations, energy dispersive spectrophotometry (EDS) to semiquantitatively assess chemical composition using the Ca/P ratio, and the x-ray diffraction (XRD) technique to observe alterations in enamel microstructure. The results showed that nightguard vital bleaching with 10% carbamide peroxide was effective in 96% of the cases, versus 8% for the PLA group. Dental sensitivity was present in 36% (9/25) of the cases. There was no significant association between gingival bleeding and the type of gel used (p = 1.00). In vivo laser fluorescence analysis showed no difference in values for the control group, whereas in the OPA group there was a statistically significant difference between baseline values in relation to the subsequent periods (p<0.01), with lower mean values for post-bleaching times. There was a significant difference between the groups for times T0 and T30. Micrographic analysis showed no enamel surface alterations related to the treatment performed. No significant alteration in Ca/P ratio was observed in the OPA group (p = 0.624) or in the PLA group (p = 0.462) for each of the observation periods, nor between the groups studied (p=0.102). The XRD pattern for both groups showed the presence of three-phase Hydroxyapatite according to JCPDS files (9-0432[Ca5(PO4)3(OH)], 18-0303[Ca3(PO4)2.xH2O] and 25-0166[Ca5(PO4)3(OH, Cl, F)]). No other peak associated to other phases was found, independent of the group analyzed, which reveals there was no disappearance, nucleation or phase transformation. Neither was there any alteration in peak pattern location. With the methodology and protocol used in this study, nightguard vital bleaching with 10% carbamide peroxide proved to be an effective and safe procedure for dental enamel

Efetividade do flúor e da escovação e eficácia dos materiais de colagem ionômero de vidro e resina composta na reversão das microporosidades criadas pelo condicionamento ácido no esmalte dentário

The objectives of this clinical study was to evaluate the use of the toothpaste with fluoride and without fluoride and the daily tooth brushing are effective in the reversion of the dental enamel conditioned by acid. Another objective of this clinical study was to evaluate if the positioning of orthodontic accessories with glass ionomer cement helps in the reversion of the dental enamel conditioned by acid, when compared to composed resin. One hundred and twenty teeth were selected with indication of extraction by orthodontic reasons. The 30 volunteers were divided, randomly, in two groups. A group used toothpaste without fluoride and the other with it. The teeth of the sample were shuffled, in each volunteer. The teeth were conditioned by the 37% orthophosphoric acid. One of the conditioned teeth stayed in the mouth and suffered action of the abrasion for the tooth brushing, in another teeth a stainless steel mesh protection was positioned with glass ionomer cement, in another tooth the screen was glued with composed resin, in a fourth tooth (the control) was only conditioned after the extractions, 60 days later. All the teeth were appraised through DIAGNOdent, MEVA and EDS. In the obtained data it was possible to observe that there were not statistic significant differences in any comparison, even in the group that did not have access to the fluoride in the toothpaste as in the other that had. According with the used methodology, it was possible to observe too that there was not statistic significant differences in any comparison, even in the group that had the stainless steel mesh positioned with glass ionomer cement as in the group that the stainless steel mesh was positioned with composed resin. However, it was observed that there was an improvement in the topography of the enamel in all the teeth. The accomplishment of this study was facilitated due to the participation of the researchers' of the health area (dentistry), materials engineer, physics and chemistry. The researchers were originating from the Federal University of Rio Grande do Norte and of the University of Queensland, in Australia. This interdisciplinary group was decisive in the accomplishment of the study. It can be concluded that the enamel tends to return to its initial aspect, even if the patient does not have access to fluoride. That is probably due the action of the abrasion for the tooth brushing and mastication. In spite of it not being significant, it is suggested that the conditioned enamel was more resistant to the abrasion in the group that had access to fluoride. It was also possible to conclude that the fluoride liberated by the glass ionomer was not enough to provide a significant difference in the enamel conditioned by the acid, when compared with the composed resin, even in the group that did not use fluoride in the toothpaste as in the group that used

Efetividade do uso tópico de fluoreto e da escovação no controle de cáries produzidas "in vivo"

The objective of this clinical study was to evaluate the effectiveness of the toothbrushing with and without fluoride and the daily fluoride rinse (NaF 0.05%) on produced white spot, in vivo. This was a clinical study, controlled, randomized and triple blind. Thirty patients were selected for orthodontics reasons from Orthodontics Specialization Course at the Brazilian Dental Association - Section of Rio Grande do Norte. In this study it was used 4 bicuspid upper and lower. They had orthodontic reason for extractions, in 35 days, at least. The sample had one hundred and twenty teeth that received orthodontic bands. The bands were fixed with polycarboxylate cement, and there was a space standardized between bands and one surface of teeth. The four bicuspid of each patients were randomized and nominated as A, B, C and D. These nominations determinated the sequence of the extractions and what was done in each tooth. All the patients had been submitted to the toothbrushing with or without fluoride for 35 days. After this period, the A tooth of each patient was extracted to serve as control. The others teeth (B, C and D) were extracted one by each week. The entire sample was analyzed through the clinical examination and by laser fluorescence (DIAGNOdent®) in three different times: before orthodontic bands, 28 days after fixed and then removed the bands and, the last one, 07 days after one of the three treatments (toothbrushing with or without fluoride, tooth paste with fluoride and mouth rinse with fluoride). At the beginning all groups (A, B, C and D) had the same conditions, no significant difference was found. The same situation was found in a clinical examination. The results of the DIAGNOdent® for the groups that used tooth paste without fluoride, with fluoride and mouth rinse with fluoride, after 28 days, there was no significant difference. Clinically, the white spot was formed in all teeth after 28 days. When it was compared the three treated groups, the group without fluoride in tooth paste had worst result than the others groups. But there was no significant association between the number of active and inactive white spots and the type of treatment that the teeth had received. The demineralization of the enamel surface, under the orthodontic bands, it happened in a few weeks. The exposition of the white spots in oral environmental resulted in an improvement, but it was not enough to return to the values from the base line, either for the toothbrushing and/or the use of fluorite mouth rinse. Mouth rinse and toothpaste with fluoride have showed to reduce the incidence of demineralization in the enamel, but none seems to be superior to another one in an in vivo study

A mídia impressa sergipana nas eleições para governador em 2006: cobertura do Cinform, correio de Sergipe e jornal da cidade

The elections for governor in 2006 with its victory Marcelo Déda Workers Party (PT), were a landmark in the state of Sergipe, for the first time, called progressive fronts (an alliance of parties formed mostly by origin of the left) broke the hegemony of two political groups, Franco and the Alves, whose direction was in force for over 30 years. This study proceeds on the assumption that the print media has certain standards of conduct in covering the election period. Therefore, this study seeks to quantify, classify and compare data from three newspapers more representative of the State of Sergipe (Cinform, Cidade Journal and Correio de Sergipe) to analyze the behavior of these journals, such as private apparatus of hegemony in election coverage 2006. It also uses the concept of hegemony Gramsci and theories of journalism framing (Entman and Porto) and agenda setting (McCombs and Shaw) to identify these patterns
