INVESTIGATION OF THE EFFECT OF RING-CAVITY ON SECONDARY-COMBUSTION AND INTERIOR BALLISTIC STABILIZATION WITH LOW-TEMPERATURE SOLID PROPELLANT IN GAS EJECTION

Investigation of the effect of ring-cavity on secondary-combustion and interior ballistic stabilization with low-temperature solid propellant in gas ejection

The potential for secondary-combustion with low-temperature solid propellant in gas generation is a potential risk to ejection application.This study Dusters performed a three-dimensional dynamic numerical simulation with Re-Normalization Group turbulence model and finite-rate/eddy-dissipation model of a two-step reaction mechanism to better unders

Lung mitochondrial DNA copy number, inflammatory biomarkers, gene transcription and gene methylation in vapers and smokers

Summary: Background: Mitochondrial DNA copy number (mtCN) maintains cellular function and homeostasis, and is linked to nuclear DNA methylation Soapstone Carvings and gene expression.Increased mtCN in the blood is associated with smoking and respiratory disease, but has received little attention for target organ effects for smoking or electronic ci

Total elbow replacement in England: a protocol for analysis of National Joint Registry and Hospital Episode Statistics data

Abstract Introduction Primary total elbow replacement (TER) services in England are being restructured with the goal of centralising care to specialised centres.It is important to monitor the impact of this service redesign.This protocol outlines an intended analysis to provide detailed descriptions of the patients who are receiving primary TER, wh

An evidence base to optimise methods for involving patient and public contributors in clinical trials: a mixed-methods study

Background: In comparison with other study designs, randomised trials are regarded as particularly likely to benefit from patient and public involvement (PPI).Using mixed-methods research we investigated PPI from the perspectives of researchers and PPI contributors.Methods: Randomised trials in receipt of funding from the Health Technology Assessme
