The influence of certain astronomical and constructive parameters on the concentration of solar radiation with plane heliostats fields

In the Falck case, the far-sighted family champion of change Alberto Falck—with crucial support of the external CEO Achille Colombo—was able to de-escalate the family business

The present study is focused on the environmental parameters and a deterministic model is used to predict seasonal variations of the traffic noise, as well as the influence of the

Although the helium con- centration generally seems to be higher in the north than in the south, it appears that the most significant feature is a much larger seasonal

We argue that the structure of the Gulf Stream, and more precisely the spatial shift between velocity and temperature, plays a key role in the generation of a localized eddy flux,

For an elementary solar cell with constant dimensions and recombination velocity at the back contact, the results show an improvement of the solar cell parameters when we increase
