Bone strength index in adolescent girls: does physical activity make a difference? [PDF]
British Journal of Sports Medicine, 2005 Background: Bone strength index (BSI) combines bone mineral and bone biomechanical properties to measure resistance to bending. This index may have greater clinical significance than the more often described markers of bone mineral content (BMC), areal density, or geometry alone and, in turn, may show a stronger relation to fracture ...

Feasibility of using pozzolanicity tests to assess reactivity of wood biomass fly ashes
Građevinar, 2021 Pozzolanic activity of materials can initially be assumed from the quantity of the pozzolanic oxides SiO2, Al2O3 and Fe2O3. Some of the methods for assessing pozzolanic reactivity of materials include measurement of CaO consumption (Frattini test ...

Pre-activation negativity (PrAN): A neural index of predictive strength of phonological cues
Laboratory Phonology, 2023 We propose that a recently discovered event-related potential (ERP) component—the pre-activation negativity (PrAN)—indexes the predictive strength of phonological cues, including segments, word tones, and sentence-level tones. Specifically, we argue that PrAN is a reflection of the brain’s anticipation of upcoming speech (segments, morphemes, words ...

Assessment of the compressive strength and strength activity index of cement incorporating fly ash
IOP Conference Series: Materials Science and Engineering, 2020 Abstract In recent years, the utilizations of industrial by-product as substitute for non-renewable material in cement and concrete production has received significant attention for sustainable development goals. In this study, fly ash blended cement was produced by replacing 5%, 10%, 15%, 20%, 25%, 30% and 35% by weight of Portland ...
