Assessing subway network ground borne noise and vibration using transfer function from tunnel wall to soil surface measured by muck train operation
(2019)During the operation of urban subway rail transit system, ground vibrations are generated that transmitted through the ground and cause vibrations in nearby buildings. The operation of these systems can be characterized ... -
The autophagic response to oxidative stress in osteoarthritic chondrocytes is deregulated
(2018)It has been reported that oxidative stress (OS) is involved in the pathogenesis of osteoarthritis (OA) and that defective autophagy is accompanying this age-related disease. Moreover, it has been proposed that induction ... -
Bacterial live vaccines with graded level of attenuation achieved by antibiotic resistance mutations: transduction experiments on the functional unit of resistance, attenuation and further accompanying markers
(1998)At least 10% of spontaneous chromosomal antibiotic resistant mutants of bacteria express a strain-dependent graded reduction of virulence; this correlates linearly with a prolonged generation time. Occasionally, these ... -
Effects of low doses of different nitric oxide (NO) donors in rat models of obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD)
(2022)Several lines of evidence suggest that the intra- and inter-cellular messenger nitric oxide (NO) is critically involved in anxiety. Contrasting findings are reported, however, regarding the effects of NO donors in preclinical ... -
Noise reduction in urban LRT networks by combining track based solutions
(2016)The overall objective of the Quiet-Track project is to provide step-changing track based noise mitigation and maintenance schemes for railway rolling noise in LRT (Light Rail Transit) networks. WP 4 in particular focuses ...
