Globally, efforts are underway to reduce anthropogenic greenhouse gas emissions and to adapt to climate change impacts at the local level. However, there is a poor understanding of the relationship between city strategies on climate change mitigation and adaptation and the relevant policies at national and European level. This paper describes a comparative study and evaluation of cross-national...

The applicability of magnetic susceptibility measurements was tested to detect soil contamination from a waste site deposit in the topsoil in the vicinity of the Independence Hall, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi. Magnetic susceptibility (volume specific) measurements of the near surface topsoil (~ 15 cm top layer) were taken along four radial profiles from th...

We have implemented the sectional aerosol dynamics model SALSA (Sectional Aerosol module for Large Scale Applications) in the European-scale chemistrytransport model MATCH (Multi-scale Atmospheric Transport and Chemistry). The new model is called MATCHSALSA. It includes aerosol microphysics, with several formulations for nucleation, wet scavenging and condensation. The model reproduces observed...

introduction toxoplasma gondii is one of the most important pathogen that has adverse effect on reproductive function. evidence acquisition recent studies revealed that infection with t. gondii not only affect female reproduction, also cause male reproductive impairment. in clinical studies, high prevalence of toxoplasmosis in sterile men has been reported. in animal models, toxoplasmosis is as...

Ambient ozone (O3) concentrations tend to be higher on weekends than on weekdays in urban areas, a phenomenon known as the weekend effect. Nevertheless, its downwind influence could be diverse. The MM5-CMAQ model has been used to assess the causes of weekday/weekend O3 differences in the north-eastern Iberian Peninsula during an episode of photochemical pollution covering the whole Western Medi...

High-resolution vacuum ultraviolet carbon dioxide photoabsorption cross sections are required for modeling airglow emissions from the Martian and Venusian atmospheres and for photochemical models of those atmospheres. We report cross section measurements on CO2 at 295 and 195K between 106.1 and 118.7 nm at a spectral resolution of 0.005 nm. Significant deviations from the results of previous, l...

The comprehensive Gas Aerosol Modelling Evaluation System (GAMES) was used to investigate the impact of EU Directives on road traffic emissions scheduled for 2010 on photochemical pollution. The area under study is located in Northern Italy, where orographic features and the emissive mix represent a critical issue in ozone production and accumulation processes. The long-term period AprilSeptemb...

Climate change is one of today's most pressing global issues. Policies to guide mitigation and adaptation are needed to avoid the devastating impacts of climate change. The health sector is a significant contributor to greenhouse gas emissions in developed countries, and its climate impact in low-income countries is growing steadily. This paper reviews and discusses the literature regarding hea...

We are developing a new approach to investigate cluster magnetic field strengths and structures. It is based on the comparison of simulated Rotation Measure and radio halo images, obtained from 3dimensional multi-scale cluster magnetic fields models, with observations. This approach is applied to A2255 in which wide diffuse radio emissions and Rotation Measure images show the evidence of cluste...

Within the EU-project TRADEOFF, the impact of NOx (=NO+NO2) emissions from subsonic aviation upon the chemical composition of the atmosphere has been calculated with focus on changes in reactive nitrogen and ozone. We apply a 3-D chemical transport model that includes comprehensive chemistry for both the troposphere and the stratosphere and uses various aircraft emission scenarios developed dur...
