We report in situ spectroscopic measurements monitoring the adsorption of a series of carboxylate surfactants onto the surface of the semisoluble, ionic solid fluorite (CaF2). We employ the surface-specific technique, vibrational sum-frequency spectroscopy (VSFS), to examine the effect that surfactant adsorption has on the bonding interactions and orientation of interfacial water molecules thro...
Following the Brent Spar controversy, the OSPAR countries reached a unanimous agreement in 1998 for the future rules for disposal of petroleum installations. The vast majority of existing offshore installations will be re-used or returned to shore for recycling or disposal. For installations where there is no generic solution, one should take a case-by-case approach. We provide a survey of inte...
In the late 1970s politicians and civil servants were acutely aware of the chronic decline of the manufacturing sector as a source of employment in Britain. At a time of fear of mass unemployment, sources of new work were urgently sought. Biotechnology had been promoted by visionaries since the early twentieth century. With oil prices soaring, its potential to produce substitutes for petroleum ...
T he burning of wood is probably our oldest source for heating and cooking, and has been used by man for tens of thousands of years. Combustion of biomass, such as wood, animal dung and crop residues, is still used for cooking and heating by a large proportion of the global population, especially in less developed countries. In the industrialised world, and in countries with a cold winter clima...
Creating large conservation zones in remote areas, with less intense stakeholder overlap and limited environmental information, requires periodic review to ensure zonation mitigates primary threats and fill gaps in representation, while achieving conservation targets. Follow-up reviews can utilise improved methods and data, potentially identifying new planning options yielding a desirable balan...
Geo-information technologies are valuable tools for ecological assessment in stressed environments. Visualizing natural features prone to disasters from the oil sector spatially not only helps in focusing the scope of environmental management with records of changes in affected areas, but it also furnishes information on the pace at which resource extraction affects nature. Notwithstanding the ...
Good Life As a Social Movement Proposal for Natural Resource Use: The Indigenous Movement in Ecuador
The Ecuadorian indigenous movement has developed the concept of Good Life (Sumak Kawsay or Buen Vivir) as a conceptual weapon in order to defend the territories of indigenous nationalities as the movement itself defines them. Starting in 2002, petroleum exploitation in indigenous areas in the Amazon has been denounced as an attack against the principles of the traditional concept of Good Life. ...
