Revisão de projeto de edifício hospitalar, especialidade de hidráulica

Sendo o setor da construção civil um dos pilares do desenvolvimento económico nacional, torna-se fundamental ter uma melhor compreensão dos principais fatores que o cercam. Os dados mais atuais indicam que o cenário da construção civil em Portugal converge com a grande maioria dos países europeus. Enquanto os demais países apresentam um crescimento significativo no âmbito da reabilitação, o setor construtivo português vem apresentando um incremento notável na participação da reabilitação no cenário nacional. Apesar disso, algumas importantes obras de reabilitação estão sendo realizadas como forma de resgatar as características basilares da edificação, contudo, sem afetar de forma significativa o património da arquitetura portuguesa. Este é o caso do Centro de Saúde, o qual passou por um projeto de reabilitação em 2013 para assegurar um melhor funcionamento da unidade de saúde, entretanto, preservando diversas características que tornam aquela edificação única. O presente estudo teve como objetivo a análise das soluções adotadas para o sistema de abastecimento de água e sistema de drenagem de águas residuais e pluviais. Com o auxílio das legislações vigentes e de bibliografias externas, fez-se a verificação dos principais pontos considerados para o dimensionamento dos sistemas supracitados. No geral, o projeto realizado apresentou uma grande assertividade no que concerne a aplicação da normativa vigente e de metodologias não regulamentares, entretanto, consolidadas. Por fim, o objetivo do presente estudo foi efetuar a análise dos conceitos hidráulicos utilizados, propondo melhorias quando necessário. Contudo, os principais problemas encontrados referem-se à transparência de dados e parâmetros utilizados, os quais não foram suficientemente pormenorizados no memorial descritivo do respetivo projeto de reabilitação.Since the civil construction sector is one of the pillars of national economic development, it is essential to have a better understanding of the main factors that surrounding it. The most current data indicate that the civil construction scenario in Portugal converges with the vast majority of European countries. While the rest of the countries show significant growth in the field of rehabilitation, the Portuguese construction sector has shown a notable increment in the share of rehabilitation in the national scenario. Despite this, some important rehabilitation works are being carried out as a way to rescue the basic characteristics of the building, however, without significantly affecting the heritage of Portuguese architecture. This is the case of the Health Center, which underwent a rehabilitation project in 2013 to ensure better functioning of the health unit, however, preserving several characteristics that make that building unique. The present study had the objective of analyzing the solutions adopted for the water supply system and the wastewater and rainwater drainage system. With the aid of current legislation and bibliographies, the main points considered for the design of the aforementioned systems were verified. In general, the project carried out showed great assertiveness with regard to the application of current regulations and non-regulatory methodologies that were consolidated in the meantime. Finally, the objective of this study was to carry out the analysis of the hydraulic concepts used, proposing improvements when necessary. However, the main problems encountered refer to the transparency of the data and parameters used, which were not sufficiently detailed in the descriptive memorial of the respective rehabilitation project

Research plan for the Spanish exploratory longline fishery for Dissostichus spp. in Divisions 58.4.1 and 58.4.2: preliminary results of stage 1 (2012/13 season)

During the 2012/13 season Spain started the approved multi-year research survey in Divisions 58.4.1 and 58.4.2 in order to obtain information to better understand the population dynamics of both species of Dissostichus in areas off the Antarctic continent close to the Ross Sea and Banzare Bank, and to implement the use both local depletion and tag-recapture methods in areas described so as to estimate local abundance. The research plan, as it was stated in the proposal, takes several years to be completed. It has started in the SSRUs closest to the Ross Sea, 58.4.1H and G, during the 2012/13 season. In order to fix the protocols and ascertain the viability and suitability of the study, it was establish the return to the same areas the two-three subsequent years along with the movement to new places and westwards to SSRUs 58.4.1D, C, B and 58.4.2E is expected. The vessel Tronio has started the research plan after the exploratory fishing season in the Subarea 88.1, using the Spanish bottom longline system. A total of 42 research sets were performed within the SSRUs 58.4.1H and 58.4.1G. Two depletion experiments were completed and three prospecting-phase clusters of sets did not reach the established threshold to start the depletion. A prospective estimation of the local biomass (BLOC) of the two localized areas where the depletion experiments were performed is done and regarding the maximal and minimal biomass for the SSRUs (BSSRU) considering areas with high and low densities. This study will be reviewed and completed the upcoming years with the new data obtained revisiting the same areas as well as with the tag-recapture data in order to estimate the local abundance using two different approaches, depletion and tag-recapture methods. A summary of the activities and results from the survey is also presented related to the sampling scheme, collected samples and species

Research plan for the exploratory fisheries for Dissostichus spp. in Divisions 58.4.1 and 58.4.2 in 2013/14

The Spanish vessel Tronio started the research plan in the 2012/13 season using the Spanish bottom longline system. One depletion experiments was completed in each of the SSRU surveyed (58.4.1H and 58.4.1G). Three prospecting-phase clusters of sets did not reach the established threshold to start the depletion. A prospective estimation of the local biomass (BLOC) of the two localized areas where the depletion experiments were performed is done as well as an estimation of the biomass of the SSRUs (BSSRU), maximal and minimal, considering areas with high and low densities. A summary of the activities and results from the survey is also presented related to the sampling scheme, collected samples and species involved

Results of the Spanish exploratory longline fishery for Dissostichus spp. in divisions 58.4.1 and 58.4.2 in the 2013/14 season.

Following the Spanish research plan approved by the SC-CCAMLR XXXII, during the second year of the multi-year research survey in Divisions 58.4.1 and 58.4.2, the F/V Tronio has returned to the same places surveyed in the 2012/13 season, as well as expanded the experience westwards to the 58.4.1D and 58.4.1C SSRUs. A prospective estimation of the local biomass (BLOC) of one localized area that was visited for the commercial Spanish fleet along five seasons in the SSRU 58.4.1C is made, together with the estimation of the total Biomass in the entire SSRU using a depletion model. There have been some Antarctic toothfish recaptured that would allow, in successive years, to estimate the local abundance by tag-recapture models. The IEO is starting the process of reading otoliths with ageing purposes, data to be added in order to carry out a robust assessment of Dissotichus eleginoides stock in these divisions. Results of other data collected such as fish bycatch, incidental catch of benthic taxa or otoliths collection for ageing purposes are also presented

Results of the Spanish exploratory longline fishery for Dissostichus spp.

We addressed the revisions requested by the WG-SAM-14 regarding the results of the second year of Spanish research experience and ongoing research plan presented in WG-SAM- 14/12 and WG-SAM-14/09. A summary of the results of the Spanish research that took place in the 58.4.1 division during the last two fishing seasons is presented. A prospective estimation of the local biomass (BLOC) of three SSRUs visited using the local depletion method, together with the extrapolation to the total Biomass in the entire SSRUs, as well as an estimation of the Biomass in SSRU 58.4.1H using the mark-recapture Petersen model is made

Continuation in the 2015/16 season of the research plan initiated in 2012/13 for stocks of Dissostichus spp. in Divisions 58.4.1 and 58.4.2

In the 2012/13 fishing season Spain began implementing a multi-annual Research Plan for Divisions 58.4.1 and 58.4.2 in order to estimate local biomass of Dissostichus spp. by means of two methods: depletion and tagging. In 2014/15 the vessel was unable to conduct the proposed research experience due to problems with a blade of the propeller, During the season 2015/16 is intended to make the same proposed research with some minor changes, always subject to the ice conditions, fulfilling Spain's commitment to return to the same fishing areas in order to study inter-annual variability and maximize tag recovery, as well as, to progress research in these SSRUs (58.4.1H, G, D and C). Two research surveys have been already implemented in Division 58.4.1 and preliminary estimates of local biomass using Leslie depletion analyses have been obtained. Some recoveries of tagged toothfish have been made, both within-season and between-seasons recaptures and a preliminary Age-Length Key of Dissostichus mawsoni has been built after otholits reading from 58.4.1 division specimens. All these data will allow a robust stock assessment attempt by the end of this multiyear research survey
