On a dialogue between hard-rock aquifer mapping and hydrogeological conceptual models: insights into groundwater exploration

Groundwater is a dynamic and renewable resource, but in hard-rock terrains its availability is rather limited compared to other types of aquifer formations. Groundwater systems require a comprehensive understanding of geology, morphotectonics and hydrology, which are controlled by ground characteristics like weathering grade, fracturing degree, permeability, slope, drainage pattern and density, land cover, and climate. GIS-based integrative cartography provides an accurate way to improve knowledge on water circulation models and on the global functioning of aquifer systems. The groundwater conceptual model based in Earth systems has proven its value in water resource studies. This approach highlights the importance of groundwater exploration mapping as a useful tool to support hydrogeological conceptualisation of fractured hard-rock terrains, contributing to the sustainability of water resources.info:eu-repo/semantics/publishedVersio

Desindustrialização. Reindustrialização. Terciarização

pp. 75-88A crise que desde o início dos anos 70 atingiu a economia mundial, em particular as economias desenvolvidas de mercado, activou a discussão teórica sobre os modelos a seguir por essas economias. Na perspectiva de alguns autores a crise traduziu-se na perda de importância dos ramos que constituíram a base do crescimento econômico do pós-guerra mas também no desaparecimento de uma classe produtiva nos termos tradicionais (nomeadamente a mão-de-obra especializada). A indústria deixou de ser vista como o sector dinâmico da economia. Estamos em presença das chamadas teses da Desindustrialização

Modelos e tendências do compartilhamento de serviços: uma discussão entre governança, estratégia e territórios / Service sharing models and trends: a discussion between governance, strategy and territories

O objetivo deste texto é discutir aspectos teóricos e práticos, que envolvem governança, estratégia e configurações territoriais almejadas pelas companhias para implantação dos centros de serviços, apresentando alguns exemplos. Para tanto, foi realizada uma revisão da literatura, buscando embasamento das referidas áreas de estudo; acessados documentos corporativos atuais, que versam sobre o tema investigado; e análise de conteúdo de entrevistas semiestruturadas com especialistas em compartilhamento de serviços, com experiência em operações brasileiras e portuguesas, o que proporcionou melhor compreensão do fenômeno. Identificou-se que, apesar do cenário da crise sanitária da COVID-19, a considerar uma economia diferente no pós-pandemia, os Centros de Serviços Compartilhados continuam nas pautas de decisões empresariais. O resultado contribuiu para potencializar o papel da governança na promoção do compartilhamento de serviços, na busca do melhor modelo organizacional possível, considerando operações complexas e visando conformidade, controle e riscos. Da mesma forma, foi possível observar os aspectos estratégicos, estabelecendo conexão entre as demandas regulatórias, corporativas e mercadológicas e a implantação dos centros. Neste quesito, foi importante conhecer componentes das configurações dos territórios

Microbial water quality of public swimming pool in the district of Bragança

The poor water quality of recreational and rehabilitation pools,has been correlated to insufficient disinfection or human contamination, and can be a vehicle for transmitting diseasesto users. Because people with different characteristics attendpublic swimming pools with different purposes, the pool water quality control is essential to minimize hazards related tounsafe water.MethodsThis study was based on data collection of 144 samples between 2018 and 2020 in therapeutic and recreational pools(indoor and outdoor) in the Braganca district. The proportionof the number of bathers were estimated, as well as the microbial parameters: Total coliforms,Escherichia coli, enterococci, Pseudomonas aeruginosa, total Staphylococcus,Staphylococcus coagulase-positive and mesophilic microbial count. Results: The E. coli, enterococci and mesophilic microbial count werenot found in any sample. Unsafe pool water was mainly contaminated by both photogenicP. aeruginosa(6.3%) and total Sthaphylococcus (10.4%). Levels ofP. aeruginosaintherapeutic pools was greater than in recreational pools (indoor and outdoor) (10.5% vs 6.8% and 4.5%, respectively),while total Sthaphylococcus was absent in therapeutic pools and represent 13.6% and 10.6% of positivity in indoor and outdoors wimming pools, respectively. The bathers number medium of therapeutic, indoor and outdoor pools was 4.8, 3.4 and 6.9,respectively. Conclusions: Overall, the results endorse the good water quality of theseswimming pools, mainly by the absent of faecally-derivedbacteria. The presence of P. aeruginosain therapeutic pools canbe explained by the type of users, while the high number of bathers may promote the growth of some microorganisms,particularly in outdoor poolsinfo:eu-repo/semantics/publishedVersio

Tuberculin skin testing versus interferon-gamma release assay among users of a public health unit in Northeast Portugal

he screening of groups with a high risk for developing tuberculosis (TB) is a priority in order to control this disease. Since there is no gold standard for the diagnosis of latent TB infection (LTBI), both the tuberculin skin test (TST) and the interferon-gamma release assays (IGRA) have been used for this purpose. The aim of this study was to determine the proportion of LTBI by using the TST and the IGRA tests, and to assess the risk factors related with discordant results between tests across several risk groups advised for screening in Northeast Portugal. Data were collected from the database of patients with suspected LTBI and advised for the screening in a public health unit (January 2014 to December 2015). The proportion of LTBI was computed using both tests. Logistic regression models assessed risk factors for a positive test and for discordant results between tests. The adjusted odds ratio (OR) and respective 95% confidence interval (95% CI) were obtained. Out of 367 patients included in the analysis, 79.8% had a positive TST and 46.0% of them had a positive IGRA. In comparison with contacts of active TB cases, healthcare workers and inmates presented higher odds of TST positivity (OR 4.38, 95% CI 1.59–12.09 and OR 4.74, 95% CI 1.45–15.49, respectively), but immunocompromised people presented lower odds of TST positivity (OR 0.14; 95% CI 0.06–0.31). Instead, healthcare workers (OR 0.44, 95% CI 0.24–0.80) and immunocompromised people (OR 0.24, 95% CI 0.10–0.56) presented lower odds of a positive IGRA. There were 42.0% concordant positive results, 16.1% concordant negative results, and 41.9% discordant results, with healthcare workers presenting higher odds of discordant results (OR 3.34, 95% CI 1.84–6.05). The proportion of LTBI estimated by TST and IGRA among people advised for screening in our setting is high, highlighting the need of preventive strategies. Among healthcare workers, TST results should be read with caution as the higher proportion of discordant results with a positive TST suggests the impact of the booster reaction in this group.info:eu-repo/semantics/publishedVersio

Using engineering geosciences mapping and GIS-based tools for georesources management: lessons learned from rock quarrying

The heterogeneity of the geological properties of rock masses is very important in engineering geosciences and rock engineering issues. The study of discontinuous rock masses has developed enormously. In particular, the assessment of in situ block size plays a key role in rock engineering design projects such as mining, quarrying and highway cutting operations. The application of Geographic Information Systems to engineering geosciences has become more common. In this article, the importance of an integrative comprehensive approach to rock engineering is discussed in the context of quarrying operations, i.e., from field mapping surveys to geomechanical assessment. This approach led us to a better understanding of the appropriateness of exploitation of raw material aggregates and to reduced uncertainty about sustainability of georesources in relation to their management and the environment.info:eu-repo/semantics/publishedVersio
