Extended Hollo-Bolts (EHBs) are blind bolts that have an extended bolt shank ending in anchor nut. When used with concrete-filled tubes, the extension and concrete serve to enhance significantly performance of both connection components: tension tube face bending. The enhancements a result confining concrete, preventing local buckling steel allowing achieve tensile strength equal standard bolt+...

The aim of this study was to evaluate the response of rat subcutaneous tissue to MTA Fillapex® (Angelus), an experimental root canal filling material based on Portland cement and propylene glycol (PCPG), and a zinc oxide, eugenol and iodoform (ZOEI) paste. These materials were placed in polyethylene tubes and implanted into the dorsal connective tissue of Wistar rats for 7 and 15 days. The spec...

The article describes the experimental investigation of pool boiling heat transfer on minichannels with filling in form porous structure (copper foam). results were compared data for a smooth surface and without additional fillings. Tests carried out liquid Novec-649. Surfaces partially filled formed by inserting pieces copper foam into 5 mm depth 1 width. Minichannels completely MCC-F. measure...

Application of combining herbal medicine and biomedical material science to nerve regeneration is a new approach. In this study, we describe a novel use of purified genipin, which can be extracted from Gardenia jasminoides Ellis, fixing the gelatin to be an extracellular matrix for peripheral nerve regeneration. A 10-mm gap of rat sciatic nerve was created between the proximal and distal nerve ...

OBJECTIVE This study assessed the biocompatibility of the Epiphany endodontic sealer prepared with resinous solvent of Epiphany system (Thinning resin) in rat subcutaneous tissues. STUDY DESIGN Polyethylene tubes were filled with the sealer and 4 groups were established: GI, Epiphany prepared with 1 drop of resinous solvent (RS); GII, Epiphany prepared with 1 drop of RS and photoactivated; GI...
