TL;DR: A complex composite system with multifunctional role: bone graft material and hyperthermia generator necessary for bone cancer therapy, obtained by a co-precipitation method and characterised by XRD, FTIR and SEM.
Abstract: Our purpose was obtaining and characterizing a complex composite system with multifunctional role: bone graft material and hyperthermia generator necessary for bone cancer therapy. The designed system was a magnetite enriched collagen/hydroxyapatite composite material, obtained by a co-precipitation method. Due to the applied electromagnetic field the magnetite will induce hyperthermia and cause tumoral cell apoptosis. The complex bone graft system was characterised by XRD, FTIR and SEM, while the hyperthermia was quantify by measuring the temperature increase due to the applied alternative electromagnetical field.

TL;DR: In this article, the authors analyzed solar radiation distribution and intensity globally, continentally (all continents, except for Antarctica) and nationally (194 countries), based on the global horizontal irradiation and direct normal irradiation (DNI) data, released at the best spatial resolution available in reliable international databases.

TL;DR: In this paper, a class of double phase energy functionals arising in the theory of transonic flows were studied and their main feature is that the associated Euler equation is driven by the Baouendi-Grushin operator with variable coefficient.
Abstract: In this paper we are concerned with a class of double phase energy functionals arising in the theory of transonic flows. Their main feature is that the associated Euler equation is driven by the Baouendi-Grushin operator with variable coefficient. This partial differential equation is of mixed type and possesses both elliptic and hyperbolic regions. After establishing a weighted inequality for the Baouendi-Grushin operator and a related compactness property, we establish the existence of stationary waves under arbitrary perturbations of the reaction.
