Tracking Climate and Environmental Attention: A News‐Based Composite Index
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study introduces the Climate and Environmental Attention Index, a composite indicator that tracks media attention to climate and environmental issues. Based on the Semantic Brand Score, the proposed index extracts significant signals from unstructured text, going beyond traditional measures of word frequency and sentiment.

Voltammetric Determination of Dissolved Nitrous Oxide
International Journal of Electrochemical Science, 2011 The platinum disk electrode has been tested as a working electrode for the cathodic reduction of N2O in aqueous solutions using 0.2 M K2SO4 as supporting electrolyte, buffered at pH = 12, and a scan rate of 100 mV s-1.

Nitrous oxide in fresh water systems: An estimate for the yield of atmospheric N2O associated with disposal of human waste [PDF]
The N2O content of waters in the Potomac and Merrimack Rivers was measured on a number of occasions over the period April to July 1977. The concentrations of dissolved N2O exceeded those which would apply in equilibrium with air by factors ranging from ...

Nitrous oxide emissions from multiple combined applications of fertiliser and cattle slurry to grassland [PDF]
, 2008 Fertiliser and manure application are important sources of nitrous oxide (N2O) emissions from agricultural soils. The current default IPCC emission factor of 1.0% is independent of the type of fertiliser and manure, and application time, method and rate.

Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Detection and Mapping of Quantitative Trait Loci that Determine Responsiveness [PDF]
, 2004 Exposure to 70% N2O evokes a robust antinociceptive effect in C57BL/6 (B6) but not in DBA/2 (D2) inbred mice. This study was conducted to identify quantitative trait loci (QTL) in the mouse genome that might determine responsiveness to N2O.

EcoEnergy, EarlyView.Sulfation of TiO2 with tubular architecture assembly nanosheets cooperated with Sm modification endowed the TiO2–SO42−/MnSm catalyst with excellent low‐temperature NH3‐SCR activity, high N2 selectivity, and well H2O‐resistance. It clarifies how the Sm modification and sulfation adjusts the distribution of acid sites and modulates the activation of NH3 ...

Environmental change impacts on the C- and N-cycle of European forests: a model comparison study [Discussion paper] [PDF]
, 2012 Forests are important components of the greenhouse gas balance of Europe. There is considerable uncertainty about how predicted changes to climate and nitrogen deposition will perturb the carbon and nitrogen cycles of European forests and thereby alter ...

EcoEnergy, EarlyView.This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.
