Biomechanical and histological evaluation of a prototype bovine pericardial patch for veterinary abdominal surgery: An approximation study.

In veterinary medicine, especially within large animal medical and surgical clinics, addressing cavitary defects is a primary concern. In bovines, umbilical hernias are the most common defect, and surgical repair often necessitates the use of prosthetic materials. However, there is a high rate of recurrence with sutures or synthetic meshes, largely due to tissue contamination.

Thermoluminescent composites of sintered synthetic-topaz/ corundum for dosimetry by a novel reversible process.

Topaz (AlF(OH)SiO)/corundum (AlO) composites were prepared by a facile and novel reversible process from the sintering of synthetic topaz and AlF powders, with corundum formed into the topaz matrix. The corundum formation reaction occurs in the temperature range 875-975 °C, from 40 min sintering time, obtaining the topaz- AlF(OH)SiO/corundum- AlO composites. Although sintering temperature and time increment lead to higher corundum formation in the topaz matrix (78.
