We investigated the prevalence of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli in untreated hospital wastewaters and 2 sewage treatment plants (STPs). A collection of 252 ESBL-producing E. coli isolates from hospital wastewater and STPs were typed and tested for resistance to 17 antimicrobial agents and for the presence of integron-associated integrases (intI gene) and ESBL g...

Two respirometric principles are combined in an experimental setup based on a laboratory scale batch reactor and applied to the characterization of activated sludge and wastewater. In the first respirometric principle the temporary disturbance of the dissolved oxygen concentration in the reactor is used to estimate the respiration rate. To this end, the oxygen mass-transfer must be calculated a...

It has been widely reported that industrial control systems underpinning critical infrastructures ranging from power plants to oil refineries are vulnerable to cyberattack. A slew of countermeasures have been proposed to secure these systems, yet their adoption has been disappointingly slow according to many experts. Operators have been reluctant to spend large sums protecting against threats t...

Access to water supply and sewerage networks are essential elements of basic sanitation, however, access these is conditioned exclusionary models reflects an unequal way reproducing space. There a need critically think about political ecology that assesses the conditions this reveals asymmetries in times marked by neoliberalism, which incorporates, from new legal framework, directions for sanit...
