Delineating environmental groundwater vulnerability and protection zones mapping in fractured rock masses

Hard‐rock watersheds commonly exhibit complex geological bedrock and morphological features. Hydromineral resources have relevant economic value for the thermal spas industry. The present study aims to develop a groundwater vulnerability approach in Caldas da Cavaca hydromineral system (Aguiar da Beira, Central Portugal) which has a thermal tradition that dates back to the late 19th century, and contribute to a better understanding of the hydrogeological conceptual site model. In this work different layers were overlaid, generating several thematic maps to arrive at an integrated framework of several key‐sectors in Caldas da Cavaca site. Thus, to accomplish a comprehensive analysis and conceptualization of the site, a multi‐technical approach was used, such as, field and laboratory techniques, where several data was collected, like geotectonics, hydrology and hydrogeology, hydrogeomorphology, hydrogeophysical and hydrogeomechanical zoning aiming the application of the so‐called DISCO method. All these techniques were successfully performed and a groundwater vulnerability to contamination assessment, based on GOD‐S, DRASTIC‐Fm, SINTACS, SI and DISCO indexes methodology, was delineated. Geographical Information Systems (GIS) technology was on the basis to organise and integrate the geodatabases and to produce all the thematic maps. This multi‐technical approach highlights the importance of groundwater vulnerability to contamination mapping as a tool to support hydrogeological conceptualisation, contributing to better decision‐making of water resources management and sustainability.

Projeto de uma ETAR de 3200 habitantes equivalentes

A atividade humana e industrial usa a água para as suas atividades do quotidiano. A água é um recurso natural escasso cuja qualidade deve ser protegida, defendida, gerida e tratada em conformidade com o seu uso. Nesse âmbito, a gestão das águas prossegue objetivos de proteção da saúde humana e de preservação, proteção e melhoria da qualidade do ambiente[1]. Desde o final do seculo XIX até aos dias de hoje, verificou-se uma forte evolução nos sistemas de tratamento de águas residuais. Esta evolução foi fundamental para dar resposta às maiores exigências de qualidade do efluente tratado. O sistema de lamas ativadas é um dos processos de tratamento biológico das águas residuais mais usados em todo o mundo. Este trabalho consiste no desenvolvimento do projeto de conceção e dimensionamento de uma Estação de Tratamento de Águas Residuais (ETAR) para servir um pequeno aglomerado de cerca de 3200 habitantes equivalentes (hab.eq.), tendo como objetivo o dimensionamento de todas as etapas de tratamento necessárias ao cumprimento da legislação em vigor para a descarga das águas residuais urbanas no meio recetor. O Decreto-lei nº 152/97[2], relativo ao tratamento de águas residuais urbanas, juntamente com o Decreto-lei nº 149/2004[3] que identifica as zonas sensíveis e de zonas menos sensíveis, permitem que as entidades licenciadoras definam o grau de tratamento que a instalação deve possuir tendo em consideração a classificação do meio onde o efluente tratado é descarregado. O Decreto-Lei n.º 135/2009[1] estabelece o regime de identificação, gestão, monitorização e classificação da qualidade das águas balneares, impondo a qualidade microbiológica da água residual tratada mediante o meio recetor, e portanto conseguindo-se assim definir o tratamento de desinfeção a adotar. Resumidamente, a conceção do tratamento focou as seguintes etapas: tratamento preliminar formado por uma unidade compacta de tamisação, desarenador e desengordurador, tratamento secundário por lamas ativadas em regime de arejamento prolongado constituído por dois reatores com cerca de 400 m3 de volume seguido de um decantador com um diâmetro de 9.5 m, tratamento terciário de desinfeção composto por uma microtamisação seguido de desinfeção UV, e a utilização das operações comuns de espessamento e desidratação das lamas produzidas em excesso pelo tratamento, constituída por com um espessador gravítico com 4.6 m de diâmetro, e um filtro banda para a desidratação.

A consagração dos naturais

“One cannot analyse a legal concept outside the economic and socio-cultural context in which it was applied” – such is the longstanding thesis of António Manuel Hespanha. I argue that Hespanha’s line of argument relative to legal concepts is also applicable, mutatis mutandis, to legal agents: the magistrates, advocates, notaries, solicitors and clerks who lived and exercised their professions in a given time and place. The question, then, is how to understand the actions of these individuals in particular contexts – more specifically in late 18th century and 19th century Goa. The main goal of the present thesis was to comprehend how westernized and Catholic Goan elite of Brahman and Chardó origin who provided the majority of Goan legal agents used Portuguese law to their own advantage. It can be divided into five key points. The first one is the importance of the Constitutional liberalism regime (with all the juridical, judicial, administrative and political changes that it has brought, namely the parliamentary representation) and its relations with the perismo – a local political and ideological tendency nurtured by Goan native Catholic elite. It was explored in the chapter 2 of this thesis. The second key point is the repeated attempts made by Goan native Catholic elite to implement the jury system in local courts. It was studied in the chapter 3. Chapter 4 aims to understand the participation of the native Catholic elite in the codification process of the uses and traditions of the indigenous peoples in New Conquests territory. The fourth key point is the involvement of those elites not only in the conflict of civil and ecclesiastical jurisdictions but also in the succession of the Royal House of Sunda. It was analyzed in the chapter 5. The functions of an advocate could be delegated to someone who, though lacking a law degree, possessed sufficient knowledge to perform this role satisfactorily. Those who held a special licence to practice law were known as provisionários (from provisão, or licence, as opposed to the letrados, or lettered). In the Goa of the second half of the 18th century and the 19th century, such provisionários were abundant, the vast majority coming from the native Catholic elite. The characteristics of those provisionários, the role played by the Portuguese letrados in Goa and the difficult relations between both groups were studied in the chapter 6.

Trends in male contraception

Methods that are available for male contraception, namely coitus interruptus, condoms, and vasectomy, have been used since the 19th century. With the exceptions of a few improvements of these methods, no major progress has been made with respect to introducing new male contraceptives since then. It is extremely urgent to develop new, safe, effective, and reversible male contraceptive methods. Among all male contraceptive methods that are being investigated, the hormonal approach is the closest to clinical application. Hormonal contraception provides pregnancy protection by means of spermatogenic suppression. Androgen-progestin regimens currently represent the best available hormonal combination for induction of a profound suppression of spermatogenesis. Further development of new steroids is mandatory for increasing the choices of available contraceptive formulations and to optimize long-term safety of these regimens.

The mineralogy and chemistry of the German and Portuguese tiles used to face a historic building in the Amazon region and their natural susceptibility to tropical weathering

During the 19th century, the most prominent buildings of the city of Belém were faced entirely with tiles manufactured in Portugal and Germany, which now exhibit distinct degrees of degradation. The Pinho mansion is one of the most important of these buildings and was selected for the investigation of the action of the tropical Amazonian climate on the degradation of the tiles. To achieve this objective, the tiles were mapped for organic and inorganic degradation, and samples were collected for analysis. The minerals were determined by XRD, the chemical composition by classical wet methods and SEM/EDS, and the microorganisms under the microscope. The results show that the German and Portuguese tiles are quite different in their composition. While both ceramic bodies are composed of SiO2 and Al2O3, CaO was found only in the Portuguese tile. The low Na2O and K2O contents indicate the addition of materials to reduce the fusion temperature. SiO2 and PbO are the main constituents of the glaze, with CoO and FeO being added as pigment. The ceramic body of the German tiles is constituted of quartz, mullite, and cristobalite, in contrast with the Portuguese tiles, which are made of quartz, gehlenite, diopside, calcite, and feldspars. The glazes are XRD-amorphous. The chemical and mineralogical differences between the German and Portuguese tiles indicate that they were produced from different raw materials under distinct thermal processes. The most prominent weathering-related modifications are the thin layers (German tiles), oxidation stains, dark stains, the detachment of the tile (Portuguese tiles), loss of the glaze and powdering of the ceramic body (Portuguese tiles) through the establishment of Cyanophyta and Bacillariophyta.. The distinct degradation patterns of the tiles exposed to the tropical Amazon climate are a consequence of their distinct mineralogy and chemistry.

Myxomycetes collection preserved in the herbarium of the Federal University of Roraima (Brazil)

First records of myxomycetes in the North region of Brazil go back to the 19th century. Nevertheless, the myxobiota of this region is still largely unexplored, with only 42 species recorded, distributed in 20 genera and seven families. The objectives of this paper were to characterize the Myxomycetes collection of the Herbarium of the Federal University of Roraima (UFRR) and to add new records for the myxobiota of this State. The collection holds specimens collected in fragments of Open Ombrophilous Forest, Seasonal Semi-deciduous Forest, Riparian Forest, deforested areas and urban home gardens in the state of Roraima. The 157 exsiccates were analyzed and identified or redetermined based on identification keys, descriptions and illustrations. The collection is in good conditions of preservation and includes all subclasses of Myxomycetes, 83% of its orders, 50% of its families, and 20 species. Trichiales, with one family, three genera and six species, represents 62% of all exsiccates. Cribraria aff. splendens, Metatrichia vesparia, Physarella oblonga, Stemonaria longa and Stemonitis splendens are new records for Roraima and Arcyria obvelata, Comatricha pulchella, Stemonitis pallida and Stemonitopsis aequalis are referred for the first time in the Northern Region, enlarging the knowledge of the Brazilian geographic distribution of these species.
