Os recursos hídricos nos processos de Agenda 21 Local

Os recursos hídricos desempenham um papel crucial para a vida e para a prossecução do desenvolvimento sustentável. Hoje é amplamente reconhecido que os recursos hídricos incorporam múltiplos valores, ambientais, sociais e económicos, e múltiplos interesses também. A gestão dos recursos hídricos ultrapassa as atividades associadas ao saneamento básico, envolvendo um conjunto diverso de políticas e instrumentos p...

Heavy metal pollution in mine-soil-plant system in S. Francisco de Assis - Pana...

In Press - Available online 29 July 2013 ; The active Panasqueira mine is a tin–tungsten (Sn–W) mineralization hosted by metasediments with quartz veins rich in ferberite. The economic exploitation has been focused on wolframite, cassiterite and chalcopyrite. The mineralization also comprises several sulphides, carbonates and silver sulphosalts. The mining and beneficiation processes produces arsenic-rich m...

Avaliação do impacte da drenagem de água ácida na hidrogeoquímica do rio Zêzere...

A mineralização hidrotermal da Panasqueira localiza-se no centro de Portugal e é o maior depósito de Sn-W da Europa Ocidental. A exploração mineira e as operações do tratamento do minério deram origem a escombreiras de grandes dimensões, principalmente, nas áreas do Cabeço do Pião (escombreira do Rio) e Barroca Grande. A exploração e beneficiação dos processos de tratamento no local geraram rejeitados ricos em ...

blaCTX-M-2 and blaCTX-M-28 extended-spectrum β-lactamase genes and class 1...

Twenty-eight Klebsiella pneumoniae clinical isolates that exhibited an extended-spectrum cephalosporin-resistance profile from a city in the Northeast of Brazil were analysed by PCR and DNA sequencing in order to determine the occurrence of blaCTX-M genes and class 1 integrons. We determined the occurrence of the blaCTX-M-2 gene in six K. pneumoniae isolates and describe the first detection of the blaCTX-M-28 g...

Radiation Technology: Processes and Products - Concepts and Applications, in Ra...

The basic concepts presented in this chapter are connected with the application of ionizing radiation on microorganisms and its effects that’s enable its use for processes and products in Industry. The radiation technology process is based on the physics and chemistry of radiation interactions with matter and the quantities that are used for monitoring radiation energy depositions. The modifications in a materi...

Sterilization of an Electronical Medical Device

Radiosterilization was applied to a medical device with a “programmable memory” to allow in vivo implantation. Irradiation on a Cobalt-60 facility at 25 kGy at a dose rate of 2kGy/h corrupted the memory. Therefore an alternative sterilization method using UV was developed and validated based on ISO 11737-1 and ISO 14937. These procedures may be useful and effective for research purposes when only a small number...
