Modeling methane migration and oxidation in landfill cover materials with TOUGH2-LGM
Abstract: Methane oxidation within a Passive Methane Oxidation Barrier (PMOB) and the downward migration of molecular O2, whose presence is necessary for the oxidation reaction to occur, were simulated using the finite ...
Carrier transport properties in the vicinity of single seld-assembled quantum dots determined by low-voltage cathodoluminescence imaging
Abstract : We propose a method to investigate the carrier transport properties in the ultrathin wetting layer of a self-assembled quantum dot (QD) structure using low-voltage cathodoluminescence (CL) imaging. Measurements ...
Methanotrophs and methanotrophic activity in engineered landfill biocovers
Abstract: The dynamics and changes in the potential activity and community structure of methanotrophs in landfill covers, as a function of time and depth were investigated. A passive methane oxidation biocover (PMOB-1) was ...
Causal model to describe the spatial and temporal variation of faecal coliform concentrations in a pilot-scale test consisting of ponds aligned in series
Other titre : Causal model to describe the variation of faecal coliform concentrations in a pilot-scale test consisting of ponds aligned in series
Abstract: In this study, the application of path analysis was tested to validate a causal model developed to verify the influence on several factors of the variation of faecal coliform concentration in pilot-scale ponds ...
Dynamics and diversity of methanotrophs within an experimental landfill cover
Other titre : Diversity and dynamics of methanotrophs within an experimental landfill cover soil
Abstract: Three experimental biocovers were installed during the summer of 2006 at the St‐Nicéphore landfill in Québec (Canada). The main objectives of the experimental program were to assess the efficiency of these biocovers ...
Organization of silicon nanocrystals by localized electrochemical etching
Abstract : An approach to form a monolayer of organized silicon nanocrystals on a monocrystalline Si wafer is reported. Ordered arrays of nanoholes in a silicon nitride layer were obtained by combining electron beam ...
Resíduo do processo de reciclagem de papel como material alternativo para aplicações em geotecnia ambiental
Other titre : Paper by-product as an alternative material for geo-environmental applications
Resumo: Para fabricar papel a partir de aparas é preciso separar as fibras secundárias de celulose dos agregados e contaminantes do papel. Devido às limitações do processo, até 30 % das fibras são perdidas na forma de ...
