Enhancing Mechanical and Combustion Performance of Boron/Polymer Composites via Boron Particle Functionalization.

High-speed air-breathing propulsion systems, such as solid fuel ramjets (SFRJ), are important for space exploration and national security. The development of SFRJ requires high-performance solid fuels with excellent mechanical and combustion properties. One of the current solid fuel candidates is composed of high-energy particles (e.

Effect of platelet rich fibrin and beta tricalcium phosphate on bone healing. A histological study in pigs.

Purpose: To investigate the effect of platelet rich fibrin (PRF) and beta tricalcium phosphate (β-TCP), alone or in combination, on bone regeneration in pig tibial defects.

Methods: Four standardized defects were prepared in both tibias of three adult male pigs. The first defect was left unfilled as a control; the others were grafted with either PRF, β-TCP or PRF mixed with β-TCP.

Gray matter changes in patients with deficit schizophrenia and non-deficit schizophrenia.

Objectives: Reduced gray matter volume is a frequently reported finding in brain imaging studies performed with schizophrenia patients. Some studies suggest a probable link between the negative symptoms of schizophrenia and gray matter loss; however, some of the negative symptoms observed in schizophrenia patients are not primarily linked to the core of schizophrenia. This study aimed to compare gray matter volumes in patients with primary negative symptoms (deficit schizophrenia [DS]), non-DS (NDS) patients, and healthy controls.
