Ball milling and AlB2 addition effects on the hydrogen sorption properties of the CaH2 + MgB2 system
2010
Among the borohydrides proposed for solid state hydrogen storage,Ca(BH4)2 is particularly interesting because of its favourable thermodynamics and relatively cheap price.Composite systems,whereother species are present in addition to the borohydride,show some advantages in hydrogen sorption properties with respect to the borohydrides alone,despite a reduction of the theoretical storage capacity. We have investigated the milling time influence on the sorption properties of the CaH2 +MgB2 system from which Ca(BH4)2 and MgH2 can be synthesized by hydrogen absorption process.Manometric and calorimetric measurements showed better kinetics forlong time milled samples.We found that the total subst…

Multiple sclerosis in twins from continental Italy and Sardinia: a nationwide study.
2005
Knowledge about the balance between heritable and nonheritable risk in multiple sclerosis (MS) is based on twin studies in high-prevalence areas. In a study that avoided ascertainment limitations and directly compared continental Italy (medium-prevalence) and Sardinia (high-prevalence), we ascertained 216 pairs from 34,549 patients. This gives a twinning rate of 0.62% among MS patients, significantly less than that of the general population. In continental Italy, probandwise concordance was 14.5% (95% confidence interval, 5.1-23.8) for monozygotic and 4.0% (95% confidence interval, 0.8-7.1) for dizygotic twins. Results in Sardinia resemble those in northern populations but in limited number…
