OBJECTIVE In this pilot study, the effect of sildenafil on digital ulcer (DU) healing and related clinical symptoms was analysed. METHODS A total of 19 patients with systemic sclerosis (SSc) were treated with maximally tolerated sildenafil doses up to 6 months. Primary outcome was the healing of DUs. Changes in other clinical symptoms were also evaluated. RESULTS In all, 49 DUs were present...
Characterization and modeling of high current conduction in TiSi2 and CoSi2 films formed on n+ Si and n+ polySi under DC and pulsed stress conditions is reported for the first time. High current conductance of silicides is shown to be strongly affected by the technology and process conditions. The non-linear I-V characteristics of silicide films under DC and pulsed high current stress has been ...
The variability of thermoelastic stresses at the Earth’s surface is investigated on different scales with a three–dimensional numerical model. Energy transfer by heat conduction and radiation of sun, atmosphere and Earth’s surface is regarded. It is shown that thermoelastic stresses are considerably high, so that they are able to assist faulting and thus force weathering of rocks. Their morphol...
