Environmental impact of combustion of ethanolic biodiesel/diesel blends from several feedstocks on the gas emission levels in the atmosphere
Evaluated ethanolic biodiesel from several feedstocks and engine operational conditions and the effect of engine operating conditions and biodiesel content in the blends during their combustion on the exhaust emissions point to crambe and macaw as more environmentally sustainable feedstocks for biodiesel production because they generate less greenhouse gas emissions.


Detection of Greenhouse Gas Precursors from Diesel Engines Using Electrochemical and Photoacoustic Sensors
The results indicate that the detection techniques used were sufficiently selective and sensitive to detect the gaseous species mentioned above in the ppmV range.
Influence of oxidized biodiesel blends on regulated and unregulated emissions from a diesel passenger car.
The results showed that the DPF had the ability to significantly reduce particulate matter (PM) emissions over all driving conditions and carbon monoxide (CO) and hydrocarbon (HC) emissions were also reduced with biodiesel; however, a notable increase in nitrogen oxide (NO(x)) emissions was observed with biod diesel blends.
Experimental Investigation of the Effect of Fuel Injection Advance on Engine Performance and Exhaust Emission Parameters Using Canola Oil Methyl Ester in a Turbocharged Direct-Injection Diesel Engine
This paper presents the effect of fuel injection advance on engine performance and exhaust emission parameters using a diesel engine running on canola oil methyl ester (COME). COME was produced and...
Irreversible climate change due to carbon dioxide emissions
The climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop, showing that thermal expansion of the warming ocean provides a conservative lower limit to irreversible global average sea level rise.
Attribution of polar warming to human influence
Polar temperatures have been warming significantly over the past few decades. A comparison between observational temperature records and model simulations shows that temperature changes in both the
Impact of urban atmospheric pollution on coronary disease.
An exhaustive search of published studies investigating links between coronary heart disease and urban atmospheric pollution supports the possibility that urban pollution is indeed an environmental cardiovascular risk factor and should be considered as such by the cardiologists.
Monitoring and Prediction of the Earth's Climate: A Future Perspective
An overview is given of a much-needed potential climate information system that embraces a comprehensive observing system to observe and track changes and the forcings of the system as they occur, and that develops the ability to relate one to the other and understand changes and their origins.
Myocardial dysfunction and potential cardiac hypoxia in rats induced by carbon monoxide inhalation.
Findings suggest that CO deteriorates heart oxygen supply to utilization and potentially may induce myocardial hypoxia through mechanisms that include increased oxygen demand due to increased contractility, reduced coronary blood flow reserve, and cardiomyocyte respiration inhibition.
Earth's Energy Imbalance: Confirmation and Implications
It is calculated that Earth is now absorbing 0.85 ± 0.15 watts per square meter more energy from the Sun than it is emitting to space, confirmed by precise measurements of increasing ocean heat content over the past 10 years.
Global Change and the Earth System: A Planet Under Pressure
The PAGES research community works toward improving our understanding of the Earth's changing environment. By placing current and future global changes in a long term perspective, they can be
