Knowledge centers as an innovative knowledge transfer mechanism : lesson learned from the program implemented in Lesser Poland

The aim of the paper is to present the lessons learnt from the "SPIN" regional public project. The project was implemented in the region of Lesser Poland. The objective of the project was to increase the intensity of knowledge transfer from universities to enterprises. The goal was achieved by establishing four Centres for Knowledge Transfer at major universities. Each of them was dedicated to a specific domain of knowledge - regional smart specialization - biotechnology, translational medicine, smart grids and energy-saving buildings. The paper discusses the implementation and effects of the project. The most important conclusions stemming from the project concern the fact that the context of the implementation needs to be taken into account during the project as well as the importance of leadership. More attention should also be devoted to the motivation and skills of those involved in the implementation

Conoscopic study of strontium-barium niobate single crystals

Optically transparent single crystals of strontium-barium niobate, Sr xBa1-xNb2O6, of different compositions (x 0.26...0.7) were examined with the aid of conoscopic light interference figures. A regular change of the isochrome concentric ring number and diameters consistent with the temperature variation of the value of birefringence is demonstrated by direct observations of polar cuts of optically uniaxial samples. Anomalous violations of the conventional (uniaxial) interference patterns occur occasionaly in some samples being indicative of the existence of biaxial trait in their behaviour even though no voltage is applied. These features may depend on annealing treatments at elevated temperatures. The results of the study show that conoscopic images may serve as a sensitive indicator of the structural state of SBN crystals related to the effects of stress-induced change of optical anisotropy and temperature dependent birefringence parameters
