Dispositivo Médico-Cirúrgico Eletromecânico para Laparoscopia

Os avanços realizados nas técnicas cirúrgicas têm permitido que o tempo de recuperação outrora contado em dias ou até semanas tenha sido reduzido para horas, com os pacientes a saírem do hospital pelo seu próprio pé pouco tempo após a intervenção. Tal resulta numa redução do tempo de recuperação, menos desconforto para o paciente e consequente redução dos custos associados ao internamento. A redução nos tempos de recuperação é fundamentalmente devida às técnicas cirúrgicas minimamente invasivas que assentam sobretudo na utilização de instrumentos laparoscópicos. A anestesia é agora muitas vezes local ou apenas uma sedação, ficando o paciente sob efeito da anestesia durante um período menor quando comparado com as técnicas tradicionais. O desenvolvimento de dispositivos laparoscópicos que permitam ao cirurgião maior manobrabilidade associada a uma atuação simples, sem os movimentos invertidos inerentes aos instrumentos tradicionais, irão permitir realizar intervenções que outrora seriam realizadas com as técnicas tradicionais, de forma segura e menos intrusiva reduzindo o risco de complicações pós-operatórias. Os dispositivos laparoscópicos mais avançados associados a certas técnicas cirúrgicas, permitem a realização de intervenções complexas e de grande minucia através de apenas um orifício LESS (Laparoendoscopic single-site surgery), ou no caso de ser realizada com robô, R-LESS (Robotic laparoendoscopic single-site surgery); reduzindo de forma ainda mais acentuada o tempo de recuperação e o tamanho da cicatriz. O aumento da manobrabilidade dos dispositivos laparoscópicos é obtida através da inclusão de sistemas eletromecânicos relativamente complexos que tentam transpor o movimento da mão para a pinça dentro do paciente. No entanto, a adição destes sistemas podem tornar a manipulação desses dispositivos pouco intuitiva e pouco ergonómica, sobretudo se forem usados com apenas uma das mãos. Por outro lado, quando a atuação deixa de ser realizada de forma puramente mecânica e direta o cirurgião perde sensibilidade da força que está a ser exercida pelo dispositivo já que esta passa a ser efetuada através de um sistema assistido, como por exemplo motores elétricos, sistemas hidráulicos ou pneumáticos. Estes fatores resultam que a aceitação destes dispositivos pelos cirurgiões não tenha sido fácil. Para contornar este problema, o dispositivo desenvolvido para além de grande capacidade de manobra, oferece atuação natural e portabilidade. Contempla uma componente háptica de atuação hidráulica que ajudará o cirurgião a melhor perceci-onar o que se passa na ponta da pinça. Como o movimento da pinça é controlado por um sistema eletromecânico é possível escalonar a amplitude do movimento de entrada e reduzir o tremor fisiológico das mãos. A pinça e respetiva haste é convencional podendo ser usados os trocarts já existentes. Foi desenvolvido um protótipo virtual com todos os componentes necessários para um funcionamento integral. No então não foram realizados protótipos físicos de todos os componentes, nem se sabe como os diferentes módulos interagem entre si.

Metodologia para implantação de um sistema de disposição de rejeitos em minério de ferro na região do semiárido: estudo de caso

Tailings dams are structures that aims to retain the solid waste and water from mining processes. Its analysis and planning begins with searching of location for deployment, step on which to bind all kinds of variables that directly or indirectly influence the work, such as geological, hydrological, tectonic, topographic, geotechnical, environmental, social characteristics, evaluation security risks, among others. Thus, this paper aims to present a study on the most appropriate and secure type of busbar to design a layout structure of iron ore tailings, taking into account all the above mentioned variables. The case study involves the assessment of sites for location of dams of tailings disposal beneficiation of iron mine to be built in Bonito, in the municipality of Jucurutu in Seridó Potiguar. For site selection among alternatives, various aspects of the current state of the art were considered, one that causes the least environmental impact, low cost investment, adding value to the product and especially the safety of the implanted structure mitigates the concern about induced earthquakes as a result of liquefaction wastes somatized by dams in the region, as the tilling of Mina Bonito is located practically in the hydraulic basin dam Armando Ribeiro in environmental protection (APA). The methodology compares induced by dams in the semiarid region with the characteristics of the waste disposal and sterile seismicity, taking into account the enhancement of liquefaction by the action of seismicity in the Mina Bonito region. With the fulcrum in the methodology, we indicated the best busbar type for disposal of tailings from iron ore or combination of them, to be designed and built in semiarid particularly for Mina Bonito. Also presents a number of possible uses for the tailings and in engineering activities, which may cause processing to the common good.

O sistema aquífero Barreiras na região de Parnamirim, RN: uso das águas e potencialidades

The study area is within the Pirangi River Basin, eastern sector of Rio Grande do Norte state, where is located of the Parnamirim city. It has an area of approximately 370 km². Urbanization has developed much fast without an appropriate infrastructure, mainly by the lack of sewage systems, with risks of contamination of groundwater that may cause serious damage to the health of the population. The Barreiras Aquifer System groundwater in the area represents the main source of water supply for urban and rural populations. The use of groundwater occurs without adequate planning and therefore, important recharge areas are being occupied. This study was conducted to quantify the use and evaluation of the potential of groundwater, in order to increase good water quality supply and lower risks of being affected by polluting activities. With these objectives, the following activities were carried out: 268 points of water have been registered; characterization of the lithological, thickness and hydrogeological structure of the Barreiras aquifer, based on the correlation of well logs; and evaluation of hydrodynamic parameters of the aquifer, from the interpretation of results well pumping tests. It was found that the saturated thickness increases from west to east towards the sea, with values ranging from 15,47-56,5 m with an average of 32,45 m. The hydrodynamic parameters using Cooper-Jacob method were: average transmissivity of 5,9x10-3 m²/s and average hydraulic conductivity 2,82x10-4 m/s. The effective porosity is of 15%, obtained by applying Biecinski equation. The potentiometric map shows the main direction of groundwater flow, from west to east, and identifies the recharge areas corresponding to the region of the tablelands of the "Barreiras". The river valleys refer to the discharge areas of the aquifer system. The Recharge was estimated at 253 mm/year, which corresponds to the 16.4% rate of infiltration.

Estudo da sismicidade na barragem do Açu no período de 2012 a 2013

The seismic activity in the Northeastern of Brazil has been a constant target of study, since it is the most active region of the country. However, some areas have their earthquakes related to human action, what means they are induced. The Açu dam is a classic example of reservoir-induced seismicity and it has been the subject of several studies. Recently, after a considerable period of inactivity, the LabSis / UFRN recorded events related to the dam, which led to the installation of a network around the reservoir. From the data provided by this network, it was observed that the seismic activity is related to a new epicental area inside the lake. The epicentral parameters and the focal mechanism were determined. It was found that the events were related to the reactivation of a basement structure in a new seismogenic subvertical fault with NE-SW-striking subparallel to the São Rafael Fault. These results were used in the preparation of a scientific paper, which discussed the relationship between this seismicity with the geology of the region and with the reservoir water level. The paper showed that the diffusion of pore pressure was the main mechanism that controlled the triggering of the induced seismicity at the reservoir.

Incisión fluvial del río Darro durante el periodo 1890-2010 en el sector urbano de Granada (Alambra-Valparaíso, España) determinada a partir de fotografías históricas

En este trabajo se calcula la tasa media de incisión fluvial del río Darro (Granada, España) durante el periodo 1890-2010 en su tramo urbano (sector Alhambra-Valparaíso). Para ello se han utilizado fotografías históricas en las que aparece dicho río, a partir de las cuales se ha podido determinar la posición del cauce en el momento en el que se realizaron las fotografías. La comparación con los escenarios actuales de tales imágenes ha permitido determinar la diferencia de altura del cauce a través de medidas de cotas absolutas realizadas mediante teodolito. Esta metodología ha permitido estimar de modo cuantitativo un índice de encajamiento vertical medio del río de 1,05 cm/año para el periodo histórico considerado.

La alquería de Pereila, un poblamiento andalusí en la Algarbía malagueña

El poblamiento rural de origen andalusí en la antigua Algarbía malagueña es un gran desconocido para la historiografía medieval. Las excavaciones y prospecciones con metodología arqueológica son prácticamente inexistentes y el recurso a la documentación escrita, en concreto la de origen castellana, ha dado un resultado muy limitado. Como excepción tenemos la información correspondiente al antiguo espacio residencial de Pereila y su territorio. La alquería estaba situada dentro del actual término municipal de Coín (Málaga) y un pleito en el 1537 entre el cabildo Catedralicio de Málaga y los beneficiados de Coín por el cobro del diezmo de dicho lugar, nos ha aportado una información valiosa sobre los límites territoriales del poblamiento, y en menor medida, de sus espacios de trabajo. También utilizaremos la metodología propia de la arqueología extensiva y los principios de la arqueología hidráulica que nos servirán para complementar la información aportada por la documentación escrita.

Agua y desarrollo urbano en la Castilla medieval: aportaciones a su estudio en la ciudad de Guadalajara

Uno de los elementos críticos del urbanismo castellano en la Edad Media era el acceso a recursos hídricos que pudieran servir para el abastecimiento humano. En función del clima, la orografía, y las infraestructuras heredadas de épocas anteriores, cada ciudad y villa del reino trató de buscar la mejor manera de asegurar el suministro de agua para sus vecinos. A lo largo de este trabajo se analiza la forma en la que el concejo de Guadalajara, así como los principales poderes religiosos y nobiliarios de la ciudad, fueron trazando la red de abastecimiento urbano durante la Baja Edad Media, a partir de las fuentes del paraje conocido como El Sotillo, y cómo realizaron la explotación económica del cauce del río Henares en las cercanías del municipio. El agua, bien escaso en la Alcarria, fue durante los siglos bajomedievales un elemento de gran importancia económica y símbolo de prestigio social, que despertó el interés de todos los grupos de la sociedad arriacense.
