Compared with AC interruption, DC interruption has no natural current zero crossing in the process of current interruption. The objective of this paper is to propose an arc-less DC vacuum breaker ...

The residual axial magnetic field (AMF) at current zero, which is caused by large di/dt during the forced currentzero stage of DC interruption based on the technique of artificial current zero, has a ...

The literature is limited about fractionation of essential oil components using batch vacuum distillation. Farah et al. (2006) report the use of fractional distillation to separate components of ...

These observations were only possible due to processing by vacuum distillation of essential oils, and thus, obtaining new fraction for the testing of volatile compounds against the cattle ticks.
