Numerical analysis of ACSR conductor-clamp systems undergoing wind-induced cyclic loads
Abstract—Submitted to wind induced vibrations, overhead conductors are vulnerable to fatigue damage, especially at restraining fixtures such as the suspension clamp. This paper proposes an efficient finite element ...
UV laser controlled quantum well intermixing in InAlGaAs/GaAs heterostructures
Abstract : The influence of surface irradiation of GaAs with a KrF excimer laser on the magnitude of the quantum well intermixing (QWI) effect has been investigated on GaAs/AlGaAs and GaAs/AlGaAs/InAlGaAs QWs heterostructures. ...
Determination of the soil water characteristic curve of highly compressible materials: Case study of pulp and paper by-product
Abstract: A technique was developed for the determination of various points of the soil-water characteristic curve (SWCC)—including the air entry value (AEV)—of compressible materials from one single test. The testing ...
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 ...
Suction profiles and scale factors for unsaturated flow under increased gravitational field
Abstract: Scale factors for centrifuge modelling have been traditionally defined using dimensional analysis concepts. This is the case, for example, of centrifuge modelling of unsaturated water flow. However, scale factors ...
A simple field method to qualify the state of saturation in capillary barriers
Abstract: A simple and straightforward field method to rapidly qualify the state of saturation of moisture retaining layers (MRL) is proposed and the details of its calibration and operation, described. The technique is ...
Anaerobic biodegradation of an organic by-products leachate by interaction with different mine tailings
Abstract: Deinking by-products from paper recycling has been used as cover material on acid-producing tailings. Due to remaining cellulose, anaerobic degradation leads to the production of an organic-rich leachate, which ...
Behaviour of tire shred – sand mixtures
Abstract: Tire shreds and tire shred-soil mixtures can be used as alternative backfill material in many geotechnical applications. The reuse of tire shreds may not only address growing environmental and economic concerns, ...
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 ...
