Legal Issues regarding Software Use and Reuse within the European Union Legislation
No full textThis paper addresses the problem of legal issues in the use and reuse of a software artifact with reference to the European Union regulations. Up to now software have been protected by means of the author law, however they are very different from other artifacts subject to the author law. This problem is getting more urgent as reuse is becoming a widely used software development methodology. Guidelines for implementing an" almost safe" contract for using and reusing software artifact are presented here. Questions regarding common misconceptions of the rights of the purchasers are also described

Occurrence of DNA sequence differences in C-heterochromatin of Eulemur coronatus and Eulemur macaco, as revealed by fluorescence resonance energy transfer.
No full textIn the genus Eulemur (Malagasy lemurs) karyotype diversification has occurred mainly through Robertsonian mechanisms of chromosome fusion (Rumpler et al., 1976). Eulemur coronatus is the sole species to have the largest genome size, due to a very large amount of C-heterochromatin, mostly located at the pericentromeric regions of the largest chromosomes (Warter and Rumpler, 1985). This increase in C-heterochromatin was thought to be due to DNA amplification (Ronchetti et al., 1993). The aim of this work was to investigate whether the large C-heterochromatin of Eulemur coronatus might have derived by amplification of the smaller C-heterochromatin of Eulemur macaco, a closely related species with smaller genome size. To obtain information on the overall base composition of the total genomes, on the relative interspersion of AT and GC base paris along the DNA molecule and on the structural differences in C-heterochromatin, we used a quantitative cyto-chemical approach, based on fluorescence resonance energy transfer (FRET) between DNA-specific fluorochromes (i.e. the AT-specific Hoechst 33258, and the non base-specific dye, propidium iodide). Micro-spectrofluorometry and image analysis were used to investigate both the overall FRET efficiency and its spatial distribution along the chromosome arms. FRET efficiency values of the DNA in C-heterochromatin were significantly different in the two Eulemur species, indicating a different qualitative composition of repetitive DNA. This suggests that the repetitive DNA of Eulemur coronatus cannot have originated by amplification in toto of the repetitive DNA sequences of Eulemur macaco
Fate of C-24 hydrogen atoms of cholesterol during its conversion into tigogenin in Digitalis lanata
No full text(24R)-[24-3H]- and (24S)-[24-3H]-cholesterols are transformed into tigogenin [(25R)-5α-spirostan-3β-ol] in Digitalis lanata without involvement of the hydrogen atoms at C-24; this confirms that the reduction of the Δ24-precursor of cholesterol is a ‘trans’ process
Origin of the 27-methylene group of the steroidal sapogenin convallamarogenin

Stereochemistry of the hydrogen introduction at C-25 in the biosynthesis of tomatidine
No full textThe C-26 atom of tomatidine, bearing the nitrogen atom, derives from the C-2 atom of MVA; from this it is inferred that the introduction of hydrogen at the C-25 atom of the Δ24 biosynthetic intermediate occurs from the 24-si, 25-si face
