The study’s primary purpose is to assess the probabilistic impact of corruption in climate finance on achieving zero emissions. This scientific problem highly relevant since largest recipients international assistance are countries with significant public sector. Thus, it necessary increase transparency use funds and strengthen accountability. study used methods survival analysis, namely Kaplan...
Abstract Procurement incentives are a widely leveraged policy lever to stimulate electric vehicle (EV) sales. However, their effectiveness in reducing transportation emissions depends on the behavioural characteristics of EV adopters. When an is used, under what conditions and by whom dictates whether or not these vehicles can deliver reductions. Here, we document that replacing gasoline powere...
Following Part 1, a comparison of CO(2)-emissions pathways between "zero-emissions stabilization (Z-stabilization)" and traditional stabilization is made under more realistic conditions that take into account the radiative forcings of other greenhouse gases and aerosols with the constraint that the temperature rise must not exceed 2 °C above the preindustrial level. It is shown that the finding...
The growth of Eu-doped CaF2 and BaF2 thin films on Si~100!, ~110!, and ~111! substrates has been realized by molecular beam epitaxy using elemental Eu evaporation. Very bright blue emissions from Eu-doped CaF2 and yellow emissions from Eu-doped BaF2 were obtained in the wavelength range of 400–850 nm at 10 K. Depending on the Si substrate orientation, the zero-phonon line of Eu in the CaF2 thin...
California Policy Should Distinguish Biofuels by Differential Global Warming Effects Richard J. Plevin Energy and Resources University of California, Berkeley Biofuels such as ethanol offer potential greenhouse gas (GHG) reductions compared to petroleum-based liquid fuels. However, while the combustion of biomass is considered carbon neutral, the production of biofuels can result in considerabl...
Contralateral stimulation of the auditory system causes changes in levels of otoacoustic emissions. The main objective of this study was to determine the changes in the level of distortion product otoacoustic emissions for contralaterally presented unmodulated broad-band noise, or amplitude modulated broad-band noise. Two types of modulating signal were used in the investigations (sine or recta...
Widely cited ecological analyses of autism have reported associations with mercury emissions, with precipitation, and race at the level of counties or school districts. However, state educational agencies often suppress any low numerical autism counts before releasing data--a phenomenon known as "administrative censoring." Previous analyses did not describe appropriate methods for censored data...
