Short-circuit currents in turbogenerators
, 1979 The thesis is concerned with an investigation of several aspects of the short-circuit currents which arise in turbogenerators. Of particular interest is the phenomenon that one or more of the armature currents may not pass through zero for a considerable

Design of Short Circuit Indicator for Medium Voltage Systems [PDF]
, 2023 A phenomenon known as a short circuit occurs when the input terminals of a power source come into direct electrical contact with one another, which results in a very high flow of current.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
