Enteropathogenic Escherichia coli (EPEC) and Shiga toxin-producing E. coli (STEC) are pathovars of E. coli that impact human health by causing childhood diseases. In this work, 118 synanthropic rodents of the genus Rattus from Buenos Aires, Argentina were evaluated as EPEC and STEC carriers. Rectal swab samples from captured animals were evaluated by conventional PCR to detect the presence of t...

This paper analyses the impact of the corporate tax reform introduced in Italy at the beginning of 2004 on firms’ tax burden. For this purpose we develop a microsimulation model reproducing the Italian corporate tax system. The model is based on an integrated dataset combining ISTAT (Italian National Statistical Office) survey data and published accounts data for corporations, for the year 2000...

The transport of Na+, K+ and Cl- across the isolated epithelium of the eel intestine was studied using a combination of four experimental strategies: short-circuiting, measurements of intracellular potentials and ion concentrations, application of a variety of transport inhibitors and measurement of unidirectional fluxes with radioactive tracers. When short-circuited, the system performs a net ...

Bacteriophages (phages) carrying Shiga toxin genes constitute a major virulence attribute in enterohemorrhagic Escherichia coli (EHEC). Several EHEC outbreaks have been linked to food. The survival of such strains in different foods has received much attention, while the fate of the mobile Shiga toxin-converting phages (Stx phages) has been less studied. We have investigated the stability of an...

This issue does not appear to have been tackled in much detail in the literature. The analysis considers the effect of profit taxation (as a measure of investment incentive...

The vast increase in foreign assets globally has raised interest in how the home country should tax profits flowing from these investments. Broadly speaking, countries have chosen either to exempt foreign income from taxation or to subject foreign income to taxation with credits/deductions given for foreign taxes paid. Recent research has focused on the effect of these foreign income tax rules ...

Countries around the world continue to tax corporate income at significant rates despite downward pressures from international competition. Average statutory corporate income tax rates fell from 46% in 1982 to 33% in 1999, though tax bases simultaneously broadened, as a result of which average corporate tax collections actually rose from 2.1% of GDP in 1982 to 2.4% of GDP in 1999. Two pieces of...
