OBJECTIVES To quantify and compare the number of calories that school-aged Canadian children expend to meet established benchmarks for active play and organized physical activities (i.e., organized sport, physical education, active transportation). METHODS This study was informed by the benchmarks (i.e., amount of activity a child needs to be sufficiently active) and grades (i.e., how Canada ...

Topological defects frequently emerge in active matter like bacterial colonies, cytoskeleton extracts on substrates, self-propelled granular or colloidal layers and so on, but their dynamical properties and the relations to large-scale organization and fluctuations in these active systems are seldom touched. Here we reveal, through a simple model for active nematics using self-driven hard ellip...

ABSTRACT The aim of this study was to update a systematic review on the use active transportation school in Brazilian children and adolescents. All studies were extracted from LILACS; BIREME; SCIELO MEDLINE. search carried out manuscripts published period 2018-2019. descriptors used Portuguese, English Spanish. In overall, 8 included review, with 1 presenting data three periods (2009, 2012 2015...

Transparent microfluidic devices based on ZnO thin film/glass surface acoustic waves (SAWs) were explored for active cleaning its acoustofluidic performance. Acoustic generated from films glass substrate investigated and their performance including transportation, jetting nebulization evaluated. Ash particles starch solutions used as model contaminants the of ZnO/glass SAW devices, mass loading...
