TL;DR: In this paper, a polymer solar heat collector was combined with single-crystal silicon PV cells in a hybrid energy-generating unit that simultaneously produced low temperature heat and electricity, and an analytical model for the PV/T system simulated the temperature development and the performance of both the thermal and photovoltaic units.

TL;DR: In this article, a new iterative procedure was proposed to extract the level density and the γ strength function from primary γ spectra for energies close up to the neutron binding energy, which was tested on simulated spectra and on data from the 173 Yb (3 He,α) 172 Yb reaction.

TL;DR: In this paper, the authors measured the enthalpy-temperature curves for some well known supercooling salt hydrates (disodium hydrogen phosphate dodecahydrate, sodium acetate trihydrate and STL-47).

TL;DR: In this article, the level density and the gamma strength function were extracted from primary gamma spectra for energies close up to the neutron binding energy for the Yb-173(He-3,alpha)Yb-172 reaction.

TL;DR: In this paper, a new method for unfolding γ-ray spectra is described based on the fact that the contribution of Compton scattered γrays in the spectra was a slowly varying function of energy.
