Comprehensive study of a heavy fuel oil spill : modeling and analytical approaches to understanding environmental weathering
… mass spectrometry (FT-ICR MS) to examine natural weathering of the oil over a one and a half year period. Traditional GC techniques detected variable evidence of evaporation/ dissolution, biodegradation and photodegradation. Petroleum hydrocarbon compounds smaller than ~n-C16 were rapidly lost due …

Quantitative Oil Source-Fingerprinting Techniques and Their Application to Differentiating Crude Oil in Coastal Marsh Sediments
Oil source-fingerprinting is an environmental forensics technique that uses analytical chemistry to determine the origin of oil residues in environmental samples by comparison to a known or suspected source oil. Currently, the only standardized method for oil source fingerprinting is a qualitative …

The Watched Towers : Creating disjunction in a river of movement
… experience of a route through disjunction and weathering. My motivation for the route is driven by my fascination with movement along an existing spine, which stretches 700 metres from Woodstock station to the harbours edge. The route crosses eight different types of private and public …

Interface durability of externally bonded GFRP to normal and high-performance concrete
… fibers are vulnerable to attack caused by harsh environmental weathering agents such as freezing-thawing, wetting-drying, and exposure to alkaline and acidic environments. Concerned with durability, this study is based on a fracture mechanics approach to evaluate the interface durability of GFRP …

Determination of creep, fatigue and ageing characteristics of non-metallic strength members in optical communication cables
Innovative tensile, creep, fatigue, environmental weathering and ageing test methods have been developed to compare the ultimate and relative performances of four commercial brands of non-metallic continuous multi fibre strength member yarns, and one jointed non-metallic multi fibre strength member …

Impact of pavements on the urban heat island
… rapid pace of urbanization has led to several environmental challenges since the time of the Industrial Revolution. Recently however, unhindered use and modification of natural materials and ecosystems and the resulting consequences have led to a renewed focus on sustainability. Among the …
