The response of partially-confined right-circular cylinders to internal blast loading by Ozinsky, Adam

“…For the 0.5 l tests, the cylinders exhibit a linear increase in deformation with increasing charge mass, while the relationship is an exponential increase for the 0.75 l axial charge position. …”

Whole exome sequencing: a customised approach to exploring the genetic basis of musculoskeletal soft tissue injuries by Gibbon, Andrea

“…In addition, several variants previously associated with the risk of injury including TNC rs1138545 (C>T), MMP3 rs3025058 (5A>6A), rs679620 (G>A), rs591058 (C>T) and rs650108 (G>A) and COL1A1 rs1107946 (G>T) and rs1800012 (G>T), were also prioritised for investigation in additional injury cohorts. • To functionally annotate the prioritised variants using a host of in silico bioinformatic analyses tools. …”

The Efficacy of a Task-Orientated Group-Intervention Programme for Children with Specific Learning Disorder with Co-morbid Developmental Coordination Disorder by Crafford, Roche

“…Method: A quantitative, quasi-experimental design with pre- and post-tests was used. Learners were included if they presented with a primary or secondary diagnosis of SLD plus DCD (scoring at or below the 16th percentile on the Motor Assessment Battery for Children 2nd Edition (MABC-2) and a functional motor problem, as identified by the MABC checklist), aged between 6–10 years and grade 1-4. …”

Low load operation of turbine-driven boiler feed pumps by Clark, John Shaun

“…The main recommendations from the case studies were as follows: i. to stroke the steam admission valves as per the design charts, ii. to test the operation of the BFPT down to 40 % generator load, iii. to keep the pump leak-off philosophy unchanged, iv. to maintain the cooling water system and condensers sufficiently to avoid poor condenser vacuum, v. to reconsider the decommissioning of the “cold reheat” steam supply, vi. and, to favour use of the BFPT over the electric feed pumps at all generator loads.…”

Role of extracellular environment in mechanical properties of human cardiac fibroblasts and myofibroblasts by Haasbroek, Pieter Daniël

“…Rheological measurements indicated an elastic shear modulus of 500 ± 13 Pa and 2721 ± 39 Pa for PEG gels of 4% (m/v) and 10% (m/v), respectively. Specialised micro-indentation and uniaxial tensile testing found PEG gels of 7%, 10%, 14% and 18% concentration to have elastic moduli of 42.0 ± 2.8 kPa, 65.3 ±8.0 kPa, 78.2 ± 8.4 kPa, and 121.5 ± 11.9 kPa, respectively. …”
