    Dissertação de Mestrado em Gestão e Conservação da Natureza.O principal objectivo do presente estudo foi obter o Valor Económico de Uso da Reserva Florestal de Recreio do Pinhal da Paz recorrendo a dois métodos diferentes, o Método de Avaliação Contingente e o Método do Custo de Viagem. O número de visitantes do Pinhal da Paz representa cerca de 60 % dos visitantes dos parques florestais na ilha de São Miguel, concentrados sobretudo nos meses de Verão, e o seu número tem vindo a aumentar desde a abertura no ano de 2000 ultrapassando os 100 mil visitantes anuais em 2003. Um inquérito presencial, após uma visita ao parque, permitiu caracterizar os visitantes, a utilização dos diferentes serviços e o seu grau de satisfação. Os visitantes foram igualmente inquiridos sobre a sua disponibilidade de pagar uma entrada, para melhorar e manter o Parque. Cerca de 77 % dos visitantes estão disponíveis para pagar uma entrada com um valor médio de 4,73 Euros. Os resultados do modelo de avaliação contingente confirmam que a probabilidade de pagar diminui para valores superiores da entrada e está positivamente correlacionada com o nível de rendimento. O valor médio estimado da entrada é de 5,78 Euros e está associado positivamente a alguns serviços do parque nomeadamente o parque infantil. Para o modelo de custo de viagem o valor médio estimado por visitante é de 4,38 Euros. Através do Modelo de Avaliação Contingente obteve-se um valor anual de 760.700,02 Euros para o uso recreativo da Reserva Florestal de Recreio do Pinhal da Paz. Com a aplicação do Modelo de Custo de Viagem a estimativa total dos benefícios económicos do recreio e lazer no Parque do Pinhal da Paz é de 576.447,42 Euros por ano. Podemos afirmar com este estudo que o Valor Económico de Uso Recreativo do Pinhal da Paz anual está entre 576.447,42 Euros e 760.700,02 Euros (a preços de 2006).ABSTRACT: The main objective of this study was to obtain the Economic Value of Use of the Recreational Forest Reserve of “Pinhal da Paz” using two different methods, the Contingent Valuation Method and Travel Cost Method. The number of visitors to the “Pinhal da Paz” is about 60 % of visitors to forest parks on the island of São Miguel, concentrated mainly in the summer months, and their number has increased since the opening in 2000, surpassing the 100 000 visitors in the year of 2003. A presence survey, after a visit to the park, allowed characterizing visitors, the use of different services and their degree of satisfaction. Visitors were also asked about their willingness to pay an entry, to improve and maintain the Park. About 77 % of visitors are available to pay an entry with an average value of 4,73 Euros. The results of the contingent valuation model confirm that decreases the likelihood of paying for higher values of entrance and it are positively correlated with income level. The estimated average value of the entrance is of 5,78 Euros and is positively associated with certain services of the park namely the playground. For the travel cost model the estimated average value by visitor is of 4,38 Euros. Through Contingent Valuation Model was obtained an annual value of 760.700,02 Euros for the recreation use of the Recreational Forest Reserve of “Pinhal da Paz”. With the implementation of the Travel Cost Model the estimate total economic benefits of recreation and leisure in “Pinhal da Paz” Park is 576,447.42 Euros per year. We can say from this study that the annual economic value of recreation use of “Pinhal da Paz” is among 576.447,42 Euros and 760.700,02 Euros (at 2006 prices)

    Time-space evolution of Iberian Pyrite Belt igneous activity: Volcanic and plutonic lineaments, geochronology, ore horizons and stratigraphic constraints

    Get PDF
    ABSTRACT: The volcanism in the Iberian Pyrite Belt migrated from the present day west/southwest to the east/northeast during Devonian/Carboniferous times. Evidence is here discussed based in U-Pb zircon ages of felsic volcanic and plutonic rocks, bounded by enclosed sediments and their biostratigraphic ages, together with hosted massive sulphides deposits and associated plutonic counterparts.Volcano-Sedimentary Complex rocks define several volcanic axes, or lineaments, with the general NWSE to WNW-ESE belt trending orientation. The usage of all the available data from high-resolution stratigraphy, geology and geophysics lead to establishment of eleven main volcanic axes, nine with zircon U-Pb radiometric ages (166 samples).In this research, we reinforce a previous inter-axes volcanic evolutionary trend, but we also suggest an intra-axis evolutionary trend of the IPB igneous activity with time. This means the basin igneous activity also evolved along most of the volcanic and plutonic lineaments, from west/northwest to east/southeast.Successive weighted average ages for each axis (SW to NE) and opposite end-point sample ages for each axis (NW/W to SE/E) are presented. Similar trends are found with felsic volcanic rocks, subvolcanic and plutonic rocks and even massive sulphide ages correspond to the regional trend corroborating the proposed geological framework.Siliciclastic sediments and lower VSC sequences (sediments, felsic volcanic rocks and massive sulphides) show a comparable age trending evolution although upper VSC sediments seem to be contemporaneous across the province. Older ages, from zircon U-Pb and from associated reworked palynomorph in the sediments, show a long-lasting age distribution along most Devonian times, suggesting the IPB evolved since Lochkovian times (Lower Devonian). Therefore, we propose the IPB inter-axes evolution could be related with a NE-direction plate motion (present-day location) over a heat source, while intra-axes are probably due to the collisional/compressive tectonic interaction of South Portuguese - Ossa-Morena zones tectonic setting.info:eu-repo/semantics/publishedVersio

    © 2022 Sociedade Portuguesa de Cardiologia. Published by Elsevier España, S.L.U.INTRODUCTION: During the Covid-19 pandemic there has been a general belief that hospital admissions for non-infectious causes, especially cardiovascular disease, have fallen. OBJECTIVES: To assess the impact of the pandemic on admissions for ST-elevation myocardial infarction (STEMI) during the first pandemic wave. METHODS: We performed a multicenter retrospective analysis of consecutive patients presenting with STEMI in two Portuguese hospital centers in two sequential periods - P1 (March 1 to April 30) and P2 (May 1 to June 30). Patients' clinical data and hospital outcomes were compared between the two periods for the years 2017 to 2019 and for 2020. RESULTS: During P1 in 2020, a reduction in the number of STEMI patients was observed in comparison with previous years (26.0±4.2 vs. 16.5±4.9 cases per month; p=0.033), as well as an increase in the number of mechanical complications (0.0% vs. 3.0%; p=0.029). Percutaneous coronary interventions in the setting of failed thrombolysis were more frequent (1.9% vs. 9.1%; p=0.033). An overall trend for longer delays in key timings of STEMI care bundles was noted. Mortality was higher during P1 compared to previous years (1.9% vs. 12.1%; p=0.005). CONCLUSIONS: During the first Covid-19 wave fewer patients presented with STEMI at the catheterization laboratory for percutaneous coronary intervention. These patients presented more mechanical complications and higher mortality.proofepub_ahead_of_prin

    Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

    BackgroundDisorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021.MethodsWe estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined.FindingsGlobally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer.InterpretationAs the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Foram avaliadas as características das partes não-integrantes da carcaça de novilhos 5/8 Nelore 3/8 Charolês terminados em confinamento e abatidos com 425, 467 e 510 kg. Os períodos de alimentação foram 30, 65 e 94 dias, respectivamente. A idade e peso médio iniciais foram de 660 dias e 361 kg, respectivamente. A dieta alimentar, com relação volumoso:concentrado de 60:40 com base na matéria seca (MS), continha 10,25% de proteína bruta e 3,18 Mcal de energia digestível/kg MS. De acordo com estimativa da equação de regressão, os rendimentos de carcaças quente e fria elevaram com o aumento no peso de abate (P). No entanto, quando expressos por peso de corpo vazio (PCV), houve similaridade entre os diferentes tratamentos. Quando os componentes foram expressos em valores absolutos, couro, total de componentes externos (TCE), fígado, total de órgãos vitais (TOV), total de gorduras internas (TGORD) e total de trato gastrintestinal vazio (TGVZ) apresentaram incremento com o aumento no P. Quando expressos por 100 kg de P e PCV, os componentes couro, TCE, fígado e TGVZ apresentaram similaridade; coração e TOV, decréscimo; e TGORD, acréscimo, com o aumento no P. Houve correlação positiva entre peso de fígado com consumo de matéria seca (r = 0,91) e com energia líquida de mantença (ELm) (r = 0,91) e entre TGORD com ELm (r = 0,78).<br>The characteristics of the body parts non-integrant of the carcass of 5/8 Nellore 3/8 Charolais steers feedlot finished and slaughtered with 425, 467 and 510 kg, were evaluated. The feeding periods were 30, 65 and 94 days, respectively. The average initial age and weight were 660 days and 361 kg, respectively. The diet, with 60% roughage and 40% concentrate dry matter basis (DM), contained 10.25% of crude protein and 3.18 Mcal of digestible energy/kg DM. According to regression equation estimate, the hot and cold carcass dressing increased as slaughter weight (SW) increased. However, when expressed per empty body weight (EBW), similarity among the different treatments was verified. When the components were expressed in absolute values, rawhide, total external components (TEC), liver, total vital organs (TVO), total internal fats (TFAT) and total empty gastrintestinal tract (TEGT) showed increase with increase in SW. When expressed per 100 kg of body weight and EBW, the rawhide, TEC, liver and TEGT components showed similarity; heart and TVO showed decrease; and TFAT showed increase, with increase in SW. Positive correlations between liver weight with dry matter intake (r=.91) and with net energy maintenance (NEm) (r=.91), and between TFAT with NEm (r=.78) were observed
