Tailings and Mine Waste ’08 includes papers from the 12th annual Tailings and Mine Waste convention, held through Colorado nation collage of fortress Collins, Colorado. the aim of this sequence of meetings is to supply a discussion board for dialogue and institution of debate between everyone within the mining and environmental neighborhood relating to tailings and mine waste.

Ecotextiles: The way forward for sustainable development in by Mohsen Miraftab PDF

A gently selected and edited number of 23 papers from the Ecotextile 2004 convention held on the collage of Bolton, this booklet explores recycling and use of waste as uncooked fabrics in such components as garments and carpet manufacture.  The papers talk about sustainability and eco-design with issues on more desirable layout, use of sustainable fibers, and production concepts.

Benthic algae can be important primary producers in water depths of less than 50 meters (Tissot and Welte 1984, p. 22). Benthic algae are multicellular algae attached to bottom sediments. Zooplankton and other herbivores consume 40% to 95% of primary production in aquatic environments (Hobbie and Fletcher 1988) and compose up to 50% of the biomass in marine environments (Killops and Killops 1993, Fig. 1). Consequently, they contribute a large proportion of detrital organic matter to sediments. Aquatic organisms are most likely to contribute carbohydrates, proteins, and lipids to sediments (Barnes, Barnes, and Bustin 1990).

44) and is by far the most common electron acceptor in biologic oxidation-reduction reactions. Oxygen has two unpaired electrons in its outer orbitals and tends to fill these orbitals by acquiring two bonding electrons. 55). Elemental carbon has four unpaired electrons in its outer orbitals, which hold a stable configuration of eight paired electrons. Carbon can form four covalent bonds, by acquiring electrons from less electronegative elements or by losing electrons to more electronegative elements.

Elemental compositions of these groups are shown in Table 2-2. Elemental composition influences the susceptibility to bacterial decomposition and the makeup of thermal decomposition products. Organic compounds that perform structural or protective functions are resistant to bacterial decomposition and are more likely to be incorporated into sediments. Carbohydrates are the most abundant molecular group. They include sugars, such as glucose, and their polymers. Cellulose, hemicellulose, and chitin are carbohydrates that perform structural and protective functions; they can be slowly degraded by a limited group of organisms.
