Research paper thumbnail of Estimation of the input data for the prediction of road transportation emissions in Spain from 2000 to 2010 considering several scenarios

Atmospheric Environment, 2005

This paper presents a study of pollutant emissions by road vehicles in Spain for the period 2000-... more This paper presents a study of pollutant emissions by road vehicles in Spain for the period 2000-2010. This study forms part of the SETISMO project, a global study of transportation in Spain for 1988-2010, and represents the logical continuation of the analysis of pollutant emissions by road transportation in Spain for 1988-1999. The study is based on the use of COPERT III software, of wide acceptance in Europe.

Research paper thumbnail of Comparison of GHG emissions from diesel, biodiesel and natural gas refuse trucks of the City of Madrid

The fuels analysed are diesel, biodiesel 30% (B30) and compressed natural gas (CNG). The engines tested were a spark ignition engine (Otto cycle) and two compression ignition engines (Diesel cycle), the first fed with CNG and the last two with B30 and diesel. What is new about this study is its scope of application concerning refuse collection services in the city of Madrid. The tests were carried out on refuse trucks of the FCC Company along actual urban routes in the city of Madrid. Also taken into account were the energy input and the greenhouse gases emitted for each of the paths taken by the fuels analysed, from resource recovery to delivery to the vehicle tank.

Research paper thumbnail of Hepatocellular carcinoma and squamous cell carcinoma in a patient with Fanconi's anemia

We report on a 31-year-old woman who developed squamous cell carcinoma of the esophagus and hepatocellular carcinoma. Jaundice and hepatic tumor developed in 1981, after she had received oxymetholone for 10 years. Liver biopsy revealed peliosis hepatis. Androgenic therapy was stopped and the jaundice resolved. However, the hepatic tumor was observed to be unchanged. The patient died of disseminated squamous cell carcinoma, but no metastatic lesions from hepatocellular carcinoma were detected in the autopsy. The association of Fanconi's anemia and squamous cell carcinoma is reviewed, and the malignant potential of androgen-related hepatic tumors is discussed.
