Investigations on specimen design and mounting for Split Hopkinson Tension Bar (SHTB) experiments

EPJ Web of Conferences, 2015
Split Hopkinson Tension Bar (SHTB) experiments can be used to test the material behavior with high strain rates in tension loading. The influence of the specimen mounting and the specimen design on the test results was investigated.

Effects of the Reynolds Number on the Efficiency and Stall Mechanisms in a Three-stage Axial Compressor [PDF]

Journal of Applied Fluid Mechanics
The Reynolds number (Re) is an important parameter that can affect compressor performance. This study experimentally and numerically investigated the effect of Re variations on the efficiency and stall mechanisms for a three-stage axial flow compressor ...

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

Research on dynamic stiffness match form of indirect fastener based on rail high-frequency wear characteristics

Scientific Reports
The stiffness combination of the dual-layer pads in indirect fastener systems significantly influences high-frequency wheel-rail wear behavior. However, the actual stiffness exhibits strong nonlinearity and non-uniformity due to the deformation of the ...

Abatacept for Prophylaxis of Acute and Chronic Graft‐Versus‐Host‐Disease in Children Undergoing Allogeneic Hematopoietic Stem Cell Transplantation—A Systematic Review and Meta‐Analysis of Cohort Studies

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.
