Objective: The aim of this study was to compare switched on and switched off (sham) low-level laser therapy (LLLT) in the treatment of drug-induced hyposalivation. Background Data: Hyposalivation is decreased salivary flow rate most frequently present in patients who take a lot of medication, suffer from Sjögren’s syndrome, or were irradiated. Available therapies provide only short-term relief....

This article presents the effect of low magnetic field (B<10 mT) on both Negative Bias Temperature Instability (NBTI) stress and recovery. This effect is study on commercial power double diffused MOS transistors (VDMOSFET). We show that the degradation is less important when the magnetic field is applied. The dynamic of the degradation change and the relaxation is accelerated. These results can...

Low velocity impact experiments (0.14 to l km/ s) carried out in polycrystalline water ice targets at 257 and 81 K resulted in interactions which can be assigned to four fragmentation classes, cratering, erosion, disruption, and total fragmentation. Specific kinetic energies for the transitions between these classes range from l x 105 to 7 x 105 ergs/g for 81 K ice and from 3 x 105 to 2 x 106 e...
