Methodology for Allocating Municipal Solid Waste to Biogenic/Non-Biogenic Energy

REA Catalogado

Average rating: 

2

Promedio: 2 (1 reseña)

This resource contains an explanation regarding a particular concern in defining renewable energy fuels: How should municipal solid waste (MSW) be classified? Historically, because MSW has widely been viewed as being mainly composed of biomass, EIA has classified all consumption at MSW combustion plants as a renewable portion of “waste energy."

Short-term sediment resuspension on the continental slope and geochemical implications: the Faeroe-Shetland Channel

REA Auditado

Continental slopes are important and complex regions that connect shallow shelf seas with the deep ocean. Since a large part of the global primary
productivity takes place on the continental margins, knowledge on sediment
resuspension and associated processes on the continental slope is crucial
to understand the fate of particles, including biogenic debris.

Formation of β-phenylethylamine as a consequence of lipid oxidation

REA Auditado

The decarboxylation of phenylalanine in the presence of methyl 13-hydroperoxyoctadeca-9,11-dienoate (LOOH), 2,4-decadienal (DD), 4,5-epoxy-2-decenal (ED), 4-hydroxy-2-nonenal (HN), and 4-oxo-2-nonenal (ON) was studied both to explore the potential of lipid oxidation products (LOP) to produce amino acid decarboxylation and to understand the reaction pathways responsible for this degradation. All assayed LOP were able to decarboxylate phenylalanine, but their reactivity decreased in the following order when the reaction was carried out under non-oxidative conditions: DD>ED≈LOOH>HN≈ON.

Sulfur isotopes as a tracer for biogenic sulfate reduction in natural environments: A link between modern and ancient ecosystems

REA Auditado

Sulfur isotopes have been widely used to trace the activity of sulfate reducing prokaryotes in modern and ancient geochemical settings and to estimate the role of this microbial metabolism in global sulfur cycling. Extensive pure culture data provide detailed insight into cellular mechanisms involved in microbial sulfate reduction. However, studies on natural communities of sulfate reducers are required for interpreting delta34S variations in sedimentary rocks, and these are much more limited.

Environmental impact of Funerals. Life cycle assessments of activities after life.

REA Auditado

SUMMARY This research investigates the environmental impact of funerals in the Netherlands. There are multiple reasons for this research. First of all, there is interest from civilians, the funeral sector and governmental authorities.

Life cycle assessment of platform chemicals from fossil and lignocellulosic biomass scenarios : phenolic compounds, solvent, soft and hard plastic precursors

REA Auditado

One of the challenges of our time is the substitution of the existing fossil based economy by a green economy within the framework of sustainable development of our society. Biomass, especially from lignocelluloses, is a promising solution for the substitution of fuels, energy, chemicals and materials from fossil sources in a so called ―Biorefinery‖.

Discriminating between tectonism and climate signatures in palustrine deposits: Lessons from the Miocene of the Teruel Graben, NE Spain

REA Auditado

The Upper Miocene (Vallesian–Turolian) Unit II of the Teruel Graben comprises at its top a 25 m-thick sequence
of palustrine deposits. Deposition of the entire unit commenced some 9 to 7 Ma ago in a halfgraben
basin.

Retreating alpine glaciers: increased melt rates due to accumulation of dust (Vadret da Morteratsch, Switzerland)

REA Auditado

The automatic weather station (AWS) on the snout of the Vadret da Morteratsch, Switzerland, has delivered a unique 12 year meteorological dataset from the ablation zone of a temperate glacier. This dataset can be used to study multi-annual trends in the character of the surface energy budget. Since 2003 there has been a substantial darkening of the glacier tongue due to the accumulation of mineral and biogenic dust. The typical surface albedo in summer has dropped from 0.32 to 0.15. We have analysed the implications of the lowered albedo for the energy balance and the annual ablation.

Amylose and Amylopectin Hybrid Materials via Enzymatic Pathways

REA Auditado

Oligo- and polysaccharides are important macromolecules in living systems, showing their multifunctional characteristics in the construction of cell walls, energy storage, cell recognition and their immune response.
Saccharides as organic raw materials can open new perspectives on the way to new biocompatible and biodegradable products which could help to overcome the problems resulting from the upcoming restrictions of petrochemical resources.

Copepods under turbulence: grazing, behavior and metabolic rates

REA Auditado

This review focuses on the effects of small-scale turbulence on the rate processes of copepods, an important group of planktonic animals, and on their consequences for the dynamics of pelagic ecosystems. Turbulent water motion enhances the encounter rates between planktonic organisms and their food, changing the perception of the food environment for copepods and other planktonic animals. As a consequence, their feeding behaviour is affected, and the grazing rates significantly increased.
