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

open access: yesEPJ 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

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

open access: yesEPJ 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.

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

open access: yesBone & 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.

BLAST++: BLASTing queries in batches [PDF]

open access: yesBioinformatics, 2003
Abstract Summary: BLAST++ is a tool that is integrated with NCBI BLAST, allowing multiple, say K, queries to be searched against a database concurrently. The results obtained by BLAST++ are identical to that obtained by executing BLAST on each of the K queries, but BLAST++ completes the processing in a much shorter time ...

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

open access: yesFrontiers 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.

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

open access: yesEPJ 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 ...

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

open access: yesBrain 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 ...

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

open access: yesChemical 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

pp-Blast: a "pseudo-parallel" Blast [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2003
We have developed a software called pp-Blast that uses the publicly available Blast package and PVM (parallel virtual machine) to partition a multi-sequence query across a set of nodes with replicated or shared databases. Benchmark tests show that pp-Blast running in a cluster of 14 PCs outperformed conventional Blast running in large servers.
