Reduced emissions from deforestation and degredation (REDD) and its potential role in Canada's climate change action plan
Deforestation contributes approximately 20 percent of global annual carbon dioxide (CO2) emissions. Increased CO2 is thought to contribute to increased global temperatures. Proposals have been brought forward to use carbon finance to compensate developing countries for reducing emissions from …

An experimental investigation of leachate generation predictions of waste from copper sulphide ore processing
… industry is the prolonged environmental degredation of groundwater and land, resulting from Acid Mine Drainage (AMD) formation from mine wastes due to oxidation of sulphide minerals. AMD enhances the mobilisation of trace and minor metals contained in wastes, therby generating …

Characterization of clasts in the Glen Torridon region of Gale crater observed by the Mars Science Laboratory Curiosity Rover
… indicate that clasts are the products of bedrock degredation followed by extensive eolian wear.

Triplet exciton dynamics in conjugated polymer films
… to play a primary role in photo-oxidative degredation of polymer devices. Two-photon photoemission is used to probe triplet exciton relaxation dynamics in pristine conjugated polymer films and triplet-triple annihilation is determined to be an important deexcitation mechanism. Controlled …

Awakened Lambs: Jewish Armed Resistance in the Ghettos, 1939-1944
… sources, it argues that under severe human degredation and suffering, many Jews in the ghettos chose to defy their Nazi oppressors. It illustrates that it was impossible for the Jews to comprehend the fate that was being prepared for them, that the persistence of ideological disagreement …

Fast Reducer Hyperobjects
… semantics, but finds they yield a performance degredation while being linguistically unwieldy. The examination of commutative reducers leads to an empirical investigation of the scalability of traditional reducers, finding a quadratic upper bound on their performance to be loose. Parts of this …

Niche-adaptive evolution in Campylobacter jejuni
… system associated genes, and to have undergone degredation of certain loci. The ST403CC isolates also exhibited a distinct pattern of reduced genomic recombination compared to non-ST403CC C. jejuni, with evidence of lineage specific recombination events. Both generalist & specialist lineages …

Studies of Coagulation and Fibrinolysis
… the kinetics of plasmin-mediated fibrin degredation were determined. First, the mechanism of prothrombin activation by prothrombinase was investigated using two models – a one-form model which posits a single form of prothrombinase and a two-form model which posits the existence of two, …

Electrochemical Detection of Anti-Biofilm Activity Using Unnatural Amino Acid-Containing Antimicrobial Peptides
… the same AMP as active toward biofilm degredation at low (<1 mircoM) concentrations. Overall, these electrochemical biosensors utilizing models of and actual P. aeruginosa have opened up new avenues to test for effectiveness of potential anti-biofilm agents toward biofilm forming …

Degradation despite regulation : water pollution in Billings Basin, Sao Paulo, Brazil
… a less than catastrophic level of environmental degredation. These external pressures seem to have been linked to such factors as the positive response to environmental issues by new political groups ascendant in state and metropolitan politics in Sao Paulo, pragmatic action in resource …

Life Cycle Assessment der alterungsbedingten Umweltverträglichkeit biogener Hydraulik-Schmierstoffe
… at room temperature, since it causes a slower degredation by oxygen diffusion. The ageing behaviour of synthetic esters during tribological application is independent of their previous synthesis process or their storage, so that biogenic hydraulic fluids can still be used after previous storage …

Charakterisierung der Biodegradation von Silikonmammaimplantaten
… proves itself independent of long invivo-times. Degredation of tensile stress and elongation at break could be already seen after short implantation times of about 1 year, reaching a limit after an implantation period of 10 years combined to a total loss of strength of about 30% compared to …

Neural and Behavioural Consequences of Chronic Inflammation following Spinal Cord Injury
… dioxygenase (IDO) resulting in the accelerated degredation of serotonin precursor tryptophan (TRP) and increased production of TRP metabolites such as kynurenine (KYN). They have also been shown to upregulate the enzyme cyclooxygenase (COX) resulting in the increased production of pain inducing …

Manufacture and Characterization of Ionic Polymer Transducers Employing Non-Precious Metal Electrodes
… for over 150,000 cycles with very little degredation in their performance. Using this new plating method, ionic polymer membrane transducers can be made in less than five hours. Characterization of these new devices shows that they have a mass energy density of 4-20 mJ/kg in the …

Hochmoore im Erzgebirge - Untersuchungen zum Zustand und Stoffaustragsverhalten unterschiedlich degradierter Flächen
Die Hochmoore des Erzgebirges sind auf Grund ihrer jahrhunderte langen Nutzung und der ökosystemaren Wandelprozesse der vergangenen 10 - 15 Jahre unterschiedlich stark degradiert. Gleichzeitig sind sie durch den Austrag vergleichsweise hoher Austräge von DOC (Dissoloved Organic Carbon) …

Influence of SiNx/Si interface states on Si solar cells
Impact of the SiN_x/n^+-Si interface on silicon solar cell performance was investigated, where SiN_x is used as a passivation layer. Significant shifts in capacitance, conductance and leakage current characteristics were observed for metal/SiN:H/n^+-Si MOS capacitor when it was subjected to a …

Movement and habitat use of lake sturgeon (Acipenser fulvescens) in the South Saskatchewan River system
Lake Sturgeon (Acipenser fulvescens) have experienced declines in numbers throughout their range due to historical overharvesting and more recent habitat degradation. Fragmentation and disruption caused by large dams on the rivers they inhabit have greatly impacted this species. Lake Sturgeon in …
