Peroxide-Induced Synthesis of Maleic Anhydride-Grafted Poly(butylene succinate) and Its Compatibilizing Effect on Poly(butylene succinate)/Pistachio Shell Flour Composites.

Framing the Circular Bioeconomy, the use of reactive compatibilizers was applied in order to increase the interfacial adhesion and, hence, the physical properties and applications of green composites based on biopolymers and food waste derived lignocellulosic fillers. In this study, poly(butylene succinate) grafted with maleic anhydride (PBS--MAH) was successfully synthetized by a reactive melt-mixing process using poly(butylene succinate) (PBS) and maleic anhydride (MAH) that was induced with dicumyl peroxide (DCP) as a radical initiator and based on the formation of macroradicals derived from the hydrogen abstraction of the biopolymer backbone. Then, PBS--MAH was used as reactive compatibilizer for PBS filled with different contents of pistachio shell flour (PSF) during melt extrusion.

The feeling of emptiness questionnaire (CSV). elaboration and validation.

Chronic feeling of emptiness (CFE) is con- sidered a diagnostic criteria in current psychiatric classifica- tions. However, no rating scale is still available for this phe- nomenological concept, which affects diagnostic reliability and the homogeneous use of the concept among clinicians. The aim of this study is to investigate the dimensional com- ponents of CFE and elaborate a specific questionnaire.
