In order to heat the ground wires for de-icing by the Joule effect, it is necessary to first electrically isolate them from towers, as shown in Fig. 7. The de-icing current can then be supplied by a voltage transformer. With this method it becomes possible to de-ice several kilometers ...
and cost analysis. It represents an excellent launching pad into the workforce for students from multiple faculties. The cars' performance in track races, called Dynamic Events, is a key factor in the rankings. These events test the cars' longitudinal, lateral, overall performance, and reliability...
Therefore, the extracted images needed to be extended by this factor to get the scales correct with the FESEM and EDS images. (Supplementary Note 3) Afterwards, the images have been thresholded (values >10% of max intensity) in order to remove noise. Visualisation and rendering of FESEM ...
For broad parameters of \(N_{t}\) and \(N_{b}\), the temperature of nanofluids is increased. A large thermal relaxation factor \(\lambda_{1}^{*}\) rises \(\theta (\eta )\) and also the thermal boundary layer, whereas larger solutal relaxation factor \(\lambda_{2}^{*}\) dro...
In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine. The integral of power over time defines the work performed. Because this integral depends on the trajectory of the point...
Charpy impact test results are measured in joules, the SI unit for energy. This is simply the amount of work performed by a 1-newton force pushing a sample by 1 m in the direction of the force. This value can be used to calculate the impact energy in J/m2 by dividing the joule valu...

Energy prices are a major factor for production costs of basic materials3and will probably continue to be so for future green value chains. While trade with fossils has so far dampened effects of the heterogeneous availability of primary energy, long-distance transport of electricity and H2is much...
A growing body of literature suggests that without care, interfaces prove to be the limiting factor for long-term stability55,56,57,58. Our systematic approach has enabled us to decouple the losses and degradation in the bulk and at interfaces. We have shown that initial PCE can be rapidly ...
