A multispecies investigation of the strain rate sensitivity of the modulus of cortical bone [PDF]

EPJ Web of Conferences, 2021
The stiffness of cortical bone shows both inter- and intra-species variation. Currently, it is unclear whether this variation is due to differing testing protocols or an inherent feature of the material.

Deformation and damage characteristics of ball bearings under blast loading [PDF]

EPJ Web of Conferences, 2021
This paper presents the unique failure characteristics, such as fragmentation, internal cracks, general deformation and pitting, observed on a SS420C ball bearing from direct blast loading using a cylindrical PE-4 explosive. Axisymmetric simulations were

Development of a rodent high-energy blast injury model for investigating conditions associated with traumatic amputations

Bone & Joint Research, 2021
Aims: In recent conflicts, most injuries to the limbs are due to blasts resulting in a large number of lower limb amputations. These lead to heterotopic ossification (HO), phantom limb pain (PLP), and functional deficit.

Differential effects on TDP-43, piezo-2, tight-junction proteins in various brain regions following repetitive low-intensity blast overpressure

Frontiers in Neurology, 2023
IntroductionMild traumatic brain injury (mTBI) caused by repetitive low-intensity blast overpressure (relBOP) in military personnel exposed to breaching and heavy weapons is often unrecognized and is understudied.

Blast Exposure Dysregulates Nighttime Melatonin Synthesis and Signaling in the Pineal Gland: A Potential Mechanism of Blast-Induced Sleep Disruptions

Brain Sciences, 2022
Blast-induced traumatic brain injury (bTBI) frequently results in sleep-wake disturbances. However, limited studies have investigated the molecular signaling mechanisms underlying these sleep disturbances, and potentially efficacious therapies are ...

Extending the annular in-plane torsional shear test specimen to applications at high strain rates [PDF]

EPJ Web of Conferences, 2021
In-plane torsional shear testing is a well-established material testing technique in the metal forming community. The corresponding specimen is designed to be machined from sheet metal with a continuous annular shear zone intended to deform in simple ...

Study of the influence of the synthesis process on the sublimation of TATP and HMTD by thermal gravimetric analysis

Chemical Thermodynamics and Thermal Analysis, 2022
The influence of two important parameters in the synthesis of TATP (the type of catalyst and the presence or absence of stirring during the precipitation process) on its sublimation was studied by thermal gravimetric analysis. TATP synthesised with H2SO4

Characterization of muscle recruitment during gait of bilateral transfemoral and through-knee persons with limb loss

Frontiers in Bioengineering and Biotechnology, 2023
Introduction: Due to loss in musculoskeletal capacity, there is an increased burden on the residual limbs of bilateral transfemoral and through-knee persons with limb loss.
