Deteção remota aplicada à rega dos espaços verdes urbanos

A nova cultura da água visa a conservação dos recursos naturais e o aumento do rendimento produtivo da água nos espaços verdes públicos e privados. Estes espaços assumem uma relevância no bem-estar e na qualidade de vida das populações urbanas. No entanto, o aumento da área verde em climas mediterrâneos estará inevitavelmente associado ao aumento do consumo em água. A rega surge com a finalidade de fazer face às necessidades hídricas das plantas em função das caraterísticas climáticas da região. Esta situação é mais relevante quando a escolha das plantas não recai sobre as autóctones e a água para a rega tem origem na rede de distribuição de água potável. Nos últimos anos, alguns municípios em Portugal têm vindo a implementar a instalação de dois tipos distintos de contadores de água: consumo doméstico e rega. Assim, garante-se água para rega com tarifário de menor custo, visto não incluir tratamento de água residual. Desde 2012, que a vila de São Brás de Alportel implementou este sistema de rega para os jardins privados. O presente trabalho tem como objetivos o estudo da evolução dos consumos de água na rega dos espaços verdes privados que aderiram a este sistema e a monitorização da rega nos espaços verdes públicos, para uma gestão sustentável da água. A monitorização será realizada pela avaliação da qualidade dos espaços verdes através da deteção remota, integrada com a informação dos dados climáticos e dos consumos de água.info:eu-repo/semantics/publishedVersio

High connectivity of the Crocodile Shark between the Atlantic and Southwest Indian Oceans: highlights for conservation

Among the various shark species that are captured as bycatch in commercial fishing operations, the group of pelagic sharks is still one of the least studied and known. Within those, the crocodile shark, Pseudocarcharias kamoharai, a small-sized lamnid shark, is occasionally caught by longline vessels in certain regions of the tropical oceans worldwide. However, the population dynamics of this species, as well as the impact of fishing mortality on its stocks, are still unknown, with the crocodile shark currently one of the least studied of all pelagic sharks. Given this, the present study aimed to assess the population structure of P. kamoharai in several regions of the Atlantic and Indian Oceans using genetic molecular markers. The nucleotide composition of the mitochondrial DNA control region of 255 individuals was analyzed, and 31 haplotypes were found, with an estimated diversity Hd = 0.627, and a nucleotide diversity pi = 0.00167. An analysis of molecular variance (AMOVA) revealed a fixation index phi(ST) = -0.01118, representing an absence of population structure among the sampled regions of the Atlantic Ocean, and between the Atlantic and Indian Oceans. These results show a high degree of gene flow between the studied areas, with a single genetic stock and reduced population variability. In panmictic populations, conservation efforts can be concentrated in more restricted areas, being these representative of the total biodiversity of the species. When necessary, this strategy could be applied to the genetic maintenance of P. kamoharai.Foundation for Research Support of the Sao Paulo State - FAPESP [2011/23787-0, 2010/51903-2]; Portuguese Foundation for Science and Technology (FCT) [SFRH/BPD/93936/2013]; Foundation for Research Support of the Sao Paulo State - FAPESP [2011/23787-0, 2010/51903-2]; Portuguese Foundation for Science and Technology (FCT) [SFRH/BPD/93936/2013]info:eu-repo/semantics/publishedVersio

Currents issues in cardiorespiratory care of patients with post-polio syndrome

ABSTRACT Post-polio syndrome (PPS) is a condition that affects polio survivors years after recovery from an initial acute attack of the poliomyelitis virus. Most often, polio survivors experience a gradual new weakening in muscles that were previously affected by the polio infection. The actual incidence of cardiovascular diseases (CVDs) in individuals suffering from PPS is not known. However, there is a reason to suspect that individuals with PPS might be at increased risk. Method A search for papers was made in the databases Bireme, Scielo and Pubmed with the following keywords: post polio syndrome, cardiorespiratory and rehabilitation in English, French and Spanish languages. Although we targeted only seek current studies on the topic in question, only the relevant (double-blind, randomized-controlled and consensus articles) were considered. Results and Discussion Certain features of PPS such as generalized fatigue, generalized and specific muscle weakness, joint and/or muscle pain may result in physical inactivity deconditioning obesity and dyslipidemia. Respiratory difficulties are common and may result in hypoxemia. Conclusion Only when evaluated and treated promptly, somE patients can obtain the full benefits of the use of respiratory muscles aids as far as quality of life is concerned
