Obsessive-Compulsive Disorder and Attachment
Introdução: A teoria da vinculação pretende
explicar de que forma as disposições biológicas e as experiências precoces predispõem o
indivíduo à saúde mental ou à patologia.
Objetivos: Reportar um caso de Perturbação
Obsessivo-Compulsiva num jovem com padrão de vinculação ansiosa, realizando uma
revisão da literatura sobre a associação entre
as duas entidades.
Métodos: É apresentado um caso clínico de
um jovem com Perturbação Obsessivo-Compulsiva com Perturbação de Ingestão Alimentar/Restritiva e de Ansiedade Generalizada
comórbidas. O Questionário de Vinculação ao
Pai e à Mãe foi aplicado para avaliar o estilo de
vinculação. Uma análise bibliográfica sobre o
tema foi realizada, evidenciado a contribuição
dos processos de vinculação, a abordagem e o
tratamento.
Resultados: O Questionário de Vinculação ao
Pai e à Mãe evidenciou uma vinculação ansiosa no jovem.
Conclusões: O presente caso pode ilustrar
como um padrão ansioso de vinculação poderá ter influenciado o subsequente desenvolvimento de psicopatologia. Uma abordagem
psicofarmacológica, a par da psicoterapêutica
envolvendo doente e cuidadores, parece ser a
mais adequada tendo-se revelado eficaz neste

Computer-controlled ion-selective electrode switch
The construction of a microcomputer-controlled electrode switch for
use in potentiometric determinations is described. This can be coupled to most of the analytical equipment usually found in laboratories, to enable a setting up of automatic systems capable of performing sequential determinations with several ion-selective
electrodes. The assessment of its analytical usage and behaviour are discussed
Drawbacks of ovarian ablation with goserelin in women with breast cancer
In the last few years, ovarian ablation with GnRH agonists has been used as first-line adjuvant therapy in pre and perimenopausal breast cancer. These drugs suppress ovarian function in the hypothalamic-pituitary axis and they have adverse effects in other end-organs. A retrospective study was conducted on 35 premenopausal women, with breast cancer, and treated with goserelin, in order to investigate the effects of iatrogenic estrogen suppression. All women complaint of amenorrhea and only half of them referred hot-flashes, weight gain or arthralgias. Hot-flushes and arthralgias remit spontaneously in the end of the treatment. Osteodensitometry was used to access bone mass. There was a reduction in mineral bone mass and T-score at femoral neck and lumbar spine after the treatment with goserelin, but without statistical significance, except for the T-score in lumbar spine
A Desinformação pelos olhos e mãos da UE: desconstruindo e interligando narrativas e práticas digitais de (In)segurança
Muitos dos debates que se têm desenvolvido nas Relações Internacionais em torno da desinformação equacionam esta última a partir do seu impacto nas democracias, da sua utilidade e efeitos em estratégias de propaganda ou de uma combinação dos três. Nestas reflexões, gramáticas de segurança e insegurança estão frequentemente presentes de forma explícita ou implícita revelando as agendas securitárias dos diferentes atores e as formas como o digital lhes dá continuidade ou as reconfigura. A relação da União Europeia (UE) com o fenómeno e as práticas da desinformação não são uma exceção a esta dinâmica. Assumindo que o entendimento de (in)segurança depende da perspetiva política que cada ator tem sobre o mundo, este capítulo analisa como a construção da agenda política da UE face à desinformação, nomeadamente em termos de narrativas e práticas, reflete o seu lugar de fala no sistema internacional. Neste sentido, espelha, com a sua visão como ator do Norte Global, um posicionamento geopolítico e elementos identitários e securitários que, por sua vez, sustentam e revelam uma agenda digital própria – normativa e de poder.info:eu-repo/semantics/publishedVersio
Sorption of lead (Pb2+) from aqueous solutions using chars obtained in the pyrolysis of forestry pine, rubber tires and plastics
Carbonaceous solid products resulting from thermochemical processes (pyrolysis, gasification), commonly known as chars, are emerging as low-cost sorbents of metallic contaminants, being their effectiveness already demonstrated in several studies (Inyang et al., 2012; Fuente-Cuesta et al., 2012; Ko³odyñska et al., 2012; Quek and
Balasubramanian, 2009; Devecia and Kar, 2013). Given the fact that the commercial viability of pyrolysis and gasification plants for the treatment and valorisation of
waste streams are increasingly being demonstrated, it is expected that large amounts of solid chars will be available in a near future, as by-products or as main products (pyrolysis-carbonization). Chars may possess several characteristics which turn them effective as heavy metals sorbents: aromatic carbon matrix with relatively porous structures, the presence of functional groups or inorganic inclusions in the surface providing active sites to interact with metallic species (Inyang et al., 2012; Fuente-Cuesta et al., 2012; Ko³odyñska et al., 2012; Quek and Balasubramanian, 2009; Devecia and Kar, 2013; Lu et al., 2012). Lead (Pb2+) is considered as a priority substance in the field of European water policy (EU, 2000; EU, 2008) which means that measures shall be taken by the Member States to eliminate or reduce the water pollution caused by this pollutant in order to fulfill the emission/discharge limits legislated for this compound
Leaching behaviour and ecotoxicity evaluation of chars from the pyrolysis of forestry biomass and polymeric materials
The main objective of this study was to assess the environmental risk of chars derived from the pyrolysis of mixtures of pine, plastics, and scrap tires, by studying their leaching potential and ecotoxicity. Relationships between chemical composition and ecotoxicity were established to identify contaminants responsible for toxicity. Since metallic contaminants were the focus of the present study, an EDTA washing step was applied to the chars to selectively remove metals that can be responsible for the observed toxicity. The results indicated that the introduction of biomass to the pyrolysis feedstock enhanced the acidity of chars
and promote the mobilisation of inorganic compounds. Chars resulting from the pyrolysis of blends of pine and plastics did not produce ecotoxic eluates. A relationship between zinc concentrations in eluates and their ecotoxicity was found for chars obtained from mixtures with tires. A significant reduction in ecotoxicity was found when the chars were treated with EDTA, which was due to a significant reduction in zinc in chars after EDTA washing

Site selection process for new nuclear power plants-a method to support decision making and improving public participation
The Brazilian Energy Plan (PNE 2030) that guides the Government in formulating its strategy for expanding energy supply by 2030 highlights the need for the Brazilian electrical system have more than 4,000 MW from nuclear sources by 2025. Therefore, the Government presented a proposal to build four more nuclear power plants with capacity of 1,000 MW each, at first, two in the Northeast and two in Southeast. The selection and site assessment are key parts of the installation process of a nuclear plant and may significantly affect the cost, public acceptance and safety of the facility during its entire life cycle. The result of this initial stage, it can even seriously affect program success. Wrong decisions in the process of site selection may also require a financial commitment to higher planned in a later phase of the project, besides causing extensive and expensive downtime. Select the location where these units will be built is not a trivial process, because involves the consideration of multiple criteria and judgments in addition to obtaining, organizing and managing a diverse range of data, both qualitative and quantitative, to assist in decision making and ensure that the site selected is the most appropriate in relation to safety and technical, economic and environmental feasibility. This paper presents an overview of the site selection process and its stages, the criteria involved in each step, the tools to support decision making that can be used and the difficulties in applying a formal process of decision making. Also discussed are ways to make the process more transparent and democratic, increasing public involvement as a way to improve acceptance and reduce opposition from various sectors of society, trying to minimize the expense and time involved in the implementation of undertakings of this kind
