The energy ejected from the galaxy micro-quasar GRS 1915+105 in the form of jets is expected to lead to formation of an extended double lobe/hot-spot structure with an energy content comparable to an average supernova remnant. We used the Effelsberg 100m telescope at 10.45 GHz in attempt to identify such structures. For this distant galactic plane source no definite identification was possible,...

Based on recently reported results, we present arguments indicating that sign changes in proper acceleration of test particles on the symmetry axis and close to the r = 2M surface of quasi-spherical objects related to the quadrupole moment of the source might be at the origin of relativistic jets of quasars and micro-quasars.

Only a small fraction of the known X-ray binaries have radio emission and it is unclear how the presence of radio emission is related to their other physical properties. Some of these objects show well collimated jets and have been called micro-quasars. High velocity outtows at around 0.3 c were discovered from the famous X-ray bina-ries SS433 and Cygnus X-3 in the early 1980's. However more re...

In this paper, we introduce a microfluidic-based self-excited energy conversion system inspired by Kelvin's water dropper but driven by inertia instead of gravity. Two micro water jets are produced by forcing water through two micropores by overpressure. The jets break up into microdroplets which are inductively charged by electrostatic gates. The droplets land on metal targets which are gradua...

The micro-conveyor is a 9 × 9 mm manipulation surface able to move millimeter-sized planar objects in the four cardinal directions using air flows. Thanks to a specific design, the air flow comes through a network of micro-channels connected to an array of micro-nozzles. Thus, the micro-conveyor generates an array of tilted air jets that lifts and moves the object in the required direction. In ...

The paper discusses the diagnostics of plasma jets in solar corona with use data from modern space- and ground-based telescopes observing Sun extreme ultraviolet (EUV) micro- wave bands. We examine observational parameters EUV radio emission events associated jets, depending on mechanism formation, initiation conditions, evolution jets. opportunities provided by study which relies simultaneous ...
