Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Ballistic impact studies of a borosilicate glass

International Journal of Impact Engineering, 2010
The ballistic impact properties of a borosilicate ('pyrex') glass was studied using mild steel rods accelerated using a light gas gun. High-speed photography at sub-microsecond framing rates was used along with schlieren optics to investigate the propagation of elastic shock waves and fracture fronts.

The influence of impact velocity on bullet trajectory deflection through ballistic gelatine

, 2023
This paper presents the results of a study on bullet trajectory deflection, for 9 mm Luger Full Metal Jacket Round Nose (FMJ-RN) bullets fired through 23–24 cm of ballistic gelatine. The bullets were fired at different velocities. Impact velocity, energy

The Tendon‐to‐Bone Seam: A Transtendinous Approach to Rotator Cuff Repair

Arthroscopy Techniques, EarlyView.
Abstract This technique article describes the tendon‐to‐bone seam technique, a knotless, transtendinous approach to arthroscopic rotator cuff repair. The technique employs a single‐use deployment device preloaded with multiple PEEK anchors interconnected with a single polyethylene #2 suture, enabling the surgeon to create a continuous “seam” of ...

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

Clinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Experimental and numerical study on CuO/ZnO-modified aramid fabric for ballistic and UV radiation protection

Polymer Testing
Aramid fabrics are widely used in bulletproof armor because of their excellent mechanical properties. Previous studies have shown that ultraviolet radiation has a negative effect on the mechanical properties of aramid yarn, so improving the mechanical ...
