We analyze whether financial constraints of Brazilian firms are alleviated by ownership structure. More specifically, we study whether the presence of nonfinancial firms as shareholders of Brazilian firm mitigates financial constraints. We find that the presence of nonfinancial firms as...

An electron paramagnetic resonance (EPR) study of Er<Superscript>3+ </Superscript> ions in single crystals of RbTiOPO<Subscript>4</Subscript> (RTP) is presented. The EPR spectra show the existence of six different Er<Superscript>3+</Superscript> centres. The g-matrix has been determined for these centres from the analysis of the angular dependences of the spectrum in...</superscript></subscript></superscript>
