the orange-red spectrum of  the skin of  electric yellow (labidochromis caeruleus) is  one  of  the  idealistic and  necessary  schemas sought  by  aquarists  and commercial producers. in this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total length was 3.3 ± 0.35...

This paper investigates the introduction of and consequences of the “Vision Zero” (Nollvisionen) that was part of a law passed in 1997 and called for a radical reduction of deaths caused by road traffic.

In this paper, electrical heat engines driven by the Johnson-Nyquist noise of resistors are introduced. They utilize Coulomb’s law and the fluctuation–dissipation theorem of statistical physics. In these engines, resistors, capacitors and switches are the building elements. For best performance, a large number of parallel engines must be integrated to run in a synchronized fashion, and the size...
