Relatório de actividade clínica

A Medicina Dentária é uma ciência médica que envolve a prestação de cuidados de saúde ao nível da cavidade oral, maxilares e estruturas ancas. O seu exercício visa o diagnóstico das mais diversas patologias que comprometem o normal funcionamento dessas estruturas e, portanto, do corpo humano. O seu leque de atuação é vasto, as terapêuticas efetuadas têm como intuito a prevenção e o tratamento. A cárie, as doenças periodontais, a desarmonia dento-maxilar, as disfunções temporo-mandibulares, são só algumas das unidades onde esse trabalho é feito. A estética, aliada à função, é, cada vez mais, requisito obrigatório por parte do doente. As reabilitações orais extensas são cada vez mais comuns. Assim, deve o aluno, futuro clínico, receber a formação teórica e prática adequada, dispondo dos meios para que a sua prática clínica seja polivalente, crítica e competente. Este trabalho reflete não só a forma como se processa o ensino da Medicina Dentária, na Universidade Católica Portuguesa, como demonstra o funcionamento interno da Clínica Universitária. Assim, através destes dois fatores, serão interpretados os protocolos de atuação em cada área disciplinar e a base teórica que os antecede, e a forma como surge a oportunidade, ao aluno, de os colocar em prática. Foi feita uma análise estatística das diferentes variáveis em estudo, analisando, a distribuição dos pacientes pelos diferentes grupos de trabalho e interdisciplinaridade, nas diferentes áreas disciplinares. A par registaram-se os valores para análise descritiva, onde recolhemos e interpretámos, na amostra (n=63), o número de consultas ao longo das diferentes áreas médico-dentárias. Verificámos que a Medicina Dentária, na Universidade Católica é, maioritariamente, lecionada com base numa componente multidisciplinar. O correto diagnóstico e a relação que o aluno, enquanto operador, consegue estabelecer com o doente, transmitindo-lhe a possível necessidade de cuidados; são as ferramentas base. Daí, a possibilidade de exercício das mais diversas áreas clínicas será tanta quanto a capacidade, num contexto em que exista necessidade de tratamento, do operador alertar e mobilizar o doente.Dentistry is a medical area which provides services within the field of the stomatognathic system. Its exercise aims at diagnosing varied pathologies which compromise the normal functioning of that system and consequently the human body. Its scope of action is broad the therapies have made the intention to prevention and treatment t. Caries, periodontal diseases, dento-maxilar disharmony, temporomandibular dysfunctions are but some of the units upon which that work is performed. Aesthetics, alongside with function, is increasingly a compulsory requisition from the patient’s side. Extensive oral rehabilitations are more and more common. Thus, the student, a future physician, should receive the necessary theoretical training and have the technical means for his clinical practice to be polyvalent, critical and competent. This paper reflects not only the way the teaching of Dentistry is processed at Universidade Católica Portuguesa, but it also demonstrates the internal functioning of the University’s Clinic. Therefore, through these two factors, we will interpret the performance protocols, in each disciplinary area and the theoretical basis preceding them, as well as the way the opportunity arises for the student to put them into practice. A statistical analysis of the different variables at study was carried out, analyzing the distribution of the patients throughout the different work groups and interdisciplinarity within the varied disciplinary areas. Simultaneously the values were registered for descriptive analysis, where we collected and interpreted, on sample (n=63), the number of appointments throughout the different areas of dentistry. We have concluded that Dentistry at Universidade Católica is mainly taught on a multidisciplinary component basis. The correct diagnosis and the relationship which the student, as an operator, manages to establish with the patient, transmitting the need for medical care, are the base tools. Hence the possibility to exercise the most varied clinical areas will be as much as the capacity of the operator to alert and mobilize the patient in a context in which treatment is needed

Distributed active traction control system applied to the RoboCup middle size league

This work addresses the problem of traction control in mobile wheeled robots in the particular case of the RoboCup Middle Size League (MSL). The slip control problem is formulated using simple friction models for ISePorto Team robots with a differential wheel configuration. Traction was also characterized experimentally in the MSL scenario for relevant game events. This work proposes a hierarchical traction control architecture which relies in local slip detection and control at each wheel, with relevant information being relayed to a higher level responsible for global robot motion control. A dedicated one axis control embedded hardware subsystem allowing complex local control, high frequency current sensing and odometric information procession was developed. This local axis control board is integrated in a distributed system using CAN bus communications. The slipping observer was implemented in the axis control hardware nodes integrated in the ISePorto robots and was used to control and detect loss of for traction. %and to detect the ball in the kicking device. An external vision system was used to perform a qualitative analysis of the slip detection and observer performance results are presented

Análise e otimização do funcionamento de uma UTA assitida por energia solar com enfoque na roda exsicante e respetivo controlador

Tese de mestrado integrado, Engenharia de Energia e do Ambiente, Universidade de Lisboa, Faculdade de Ciências, 2016Vai-se tornando cada vez mais vital, atualmente, suprir as necessidades de consumo de energia, tais como as de eletricidade. Os sistemas de ar condicionado são responsáveis por uma grande parte desse consumo de eletricidade que se verifica no sector doméstico. De forma a suavizar os picos de consumo que se registam na época do verão, pode-se recorrer a sistemas de arrefecimento evaporativo exsicante (DEC, do inglês Desiccant Evaporative Cooling). Neste trabalho, em primeira instância, foram analisados vários dias no período de funcionamento da Unidade de Tratamento de Ar (UTA) do LNEG, desde 2003 até 2016 (atualidade). Os dias foram escolhidos segundo alguns critérios em termos de temperatura e de humidade, influenciando os processos de desumidificação e regeneração da roda exsicante e, consequentemente, o seu desempenho. Tentou estabelecer-se uma relação entre a velocidade de rotação da roda e a TCA. Esta acabou por não se verificar, no entanto o balanço de massa confirmou-se. Foram, desta forma, levados a cabo testes de análise de sensibilidade, para determinar a influência que variáveis como a temperatura, a humidade relativa e o caudal exercem na quantidade de água retida pela roda exsicante na conduta de entrada e cedida na conduta de saída, e, consequentemente, na transferência de conteúdo em água (TCA). Verificou-se que os caudais são as variáveis com mais influência na alteração das massas de água, principalmente o caudal de entrada, e as humidades relativas são as variáveis que mais influenciam a TCA. Por fim, compararam-se os caudais obtidos a partir da velocidade do ar com os caudais obtidos pelo sistema, fazendo-se assim novos testes, semelhantes aos últimos. Na maior parte dos casos, registou-se um aumento de todos os valores nas condutas de entrada e de saída de 33 e 26%, respetivamente. No entanto, para os caudais o aumento foi maior.Is becoming increasingly vital to currently meet the power consumption needs, such as electricity’s. Air conditioning systems account for a large part of that consumption of electricity that occurs in households. In order to smooth consumption peaks that are registered in summer time, we can use desiccant evaporative cooling systems. In this work, first of all, were analyzed several days in the operation period of the air handling unit of LNEG, from 2003 to 2016 (today). The days were chosen according to certain criteria in terms of temperature and humidity, which are important to take into account, as they have a strong influence in the desiccant wheel’s performance. We tried to establish a relationship between the wheel rotation speed and water transfer content. This turned out not to be seen, however the mass balance was confirmed. Were then carried out sensitivity analysis tests to determine the influence of variables such as temperature, relative humidity and flow rate have on the amount of water held in the desiccant wheel inlet duct and given away in the outlet duct, and, hence, on the water content transfer. It was found that the flow rates are the variables with more influence in the change of water masses, particularly the incoming flow, and relative humidities are the variables that most influence the water content transfer. Finally, then, it was compared flow rates obtained from the air speed with flow rates obtained by the system, thus making new tests, similar to the latter. In most cases, there was an increase of all values in the inlet and outlet ducts of 33 and 26%, respectively. However, for the flow rate the increase was greater

Atualização do sistema de descrição e análise de função para colaboradores não quadro

Mestrado em Ciências EmpresariaisOs efeitos da globalização e das alterações internas emergentes originaram a necessidade de repensar a gestão do capital intelectual dos colaboradores. Tendo isto em conta, o desafio passa por desenvolver e atualizar ferramentas de recursos humanos duma forma que melhor nos permitam analisar funções e suas respetivas competências. O objetivo do presente projeto consiste na atualização dos documentos de Descrição e Análise de Funções, aplicadas às funções não-quadro, numa multinacional da indústria química, identificando simultaneamente as competências inerentes a cada uma delas e promover ações futuras de desenvolvimento. O projeto foi desenvolvido com finalidade à resolução dos objetivos previamente identificados pela empresa, havendo por base documentação do Grupo ao qual a empresa pertence e, numa segunda fase, a técnica de entrevista por questionário a chefias para levantamento de funções e competências. Os resultados obtidos permitiram responder aos objetivos inicialmente definidos e possibilitaram dar mais um passo pela uniformização da Gestão de Recursos Humanos aplicada às funções quadro, com as não-quadro.The effects of globalization and the emerging internal changes, led to the need to rethink the management of the intellectual capital of employees. With this in mind, the challenge is to develop and update Human Resources tools in a way that will allow us to analyze functions and also competencies. The objective of this project is to update the Job Description documents, applied to the non-cadre functions, in the framework of a chemical multinational site, also identifying the core competencies inherent to each one, and propose actions and promote future developments. The project was developed to provide the resolution of the objectives previously identified by the company, using as start point the group documentation and, secondly, the interview by questionnaire to managers, for the job descriptions updates and competencies definition. The obtained results allowed to meet the initially set objectives, and also made possible to reach one more step into the standardization of the Human Resource Management applied to the cadre functions with the non-cadre functions

Características del alpechín: modelos y análisis estadístico

A synthesis of the work carried out on Olive Mill Wastewater (OMW) characterisation is given, covering articles published over the last 50 years. Data on OMW characterisation found in the literature are summarised and correlations between them and with phenolic compounds content are sought. This permits the characteristics of an OMW to be estimated from one simple measurement: the phenolic compounds concentration. A model based on OMW characterisations accounting 6 countries was developed along with a model for Portuguese OMW. The statistical analysis of the correlations obtained indicates that Chemical Oxygen Demand of a given OMW is a second-degree polynomial function of its phenolic compounds concentration. Tests to evaluate the regressions significance were carried out, based on multivariable ANOVA analysis, on visual standardised residuals distribution and their means for confidence levels of 95 and 99 %, validating clearly these models. This modelling work will help in the future planning, operation and monitoring of an OMW treatment plant.Presentamos una síntesis de los trabajos realizados en los últimos 50 años relacionados con la caracterización del alpechín. Realizamos una recopilación de los datos publicados, buscando correlaciones entre los datos relativos al alpechín y los compuestos fenólicos. Esto permite la determinación de las características del alpechín a partir de una sola medida: La concentración de compuestos fenólicos. Proponemos dos modelos, uno basado en datos relativos a seis países y un segundo aplicado únicamente a Portugal. El análisis estadístico de las correlaciones obtenidas indica que la demanda química de oxígeno de un determinado alpechín es una función polinómica de segundo grado de su concentración de compuestos fenólicos. Se comprobó la significancia de esta correlación mediante la aplicación del análisis multivariable ANOVA, y además se evaluó la distribución de residuos y sus promedios a un nivel de fiabilidad del 95 y 99 %. Este trabajo ayudará al diseño futuro de plantas de tratamiento de alpechín, así como a su funcionamiento y control

Mechanical behavior of dowel connection for timber-concrete composite rural bridges

This study focuses on the evaluation of the mechanical behavior of two types of connections for intended use in rural Timber‑Concrete Composite traffic bridges. The two connection types used were the “X” type connection – XD and the dowel type connection – PD. Firstly, static shear tests in small-scale specimens were performed in both connection types and higher results were obtained for the XD series, both for stiffness and load carrying capacity. Secondly, the PD connection was chosen, based on practical and economical aspects, for further testing also in small-scale specimens, including cyclic tests. The influence of the number of cycles in the connection stiffness and load carrying capacity was evaluated. It was concluded that the load carrying capacity increased after the application of a pre-defined number of load cycles and that the connection stiffness increased 80.6% and 34.1% after 10,000 and 1,000 cycles, respectively, for different applied load levels. Also the increase of load level in the cyclic tests affected the performance of the connection, leading to a decrease in stiffness

Environmental modeling with precision navigation using ROAZ autonomous surface vehicle

The use of robotic vehicles for environmental modeling is discussed. This paper presents diverse results in autonomous marine missions with the ROAZ autonomous surface vehicle. The vehicle can perform autonomous missions while gathering marine data with high inertial and positioning precision. The underwater world is an, economical and environmental, asset that need new tools to study and preserve it. ROAZ is used in marine environment missions since it can sense and monitor the surface and underwater scenarios. Is equipped with a diverse set of sensors, cameras and underwater sonars that generate 3D environmental models. It is used for study the marine life and possible underwater wrecks that can pollute or be a danger to marine navigation. The 3D model and integration of multibeam and sidescan sonars represent a challenge in nowadays. Adding that it is important that robots can explore an area and make decisions based on their surroundings and goals. Regard that, autonomous robotic systems can relieve human beings of repetitive and dangerous tasks
