I think I have more episodes of "flow" in programming than in cycling for sure. :-)I guess I have experienced flow during cycling a few times, mostly during climbs and long flats. And yes I knew this only after the that rather than during.I think there is a third parallel with "flo...
Both in terrestrial and aquatic environments a considerable part of organic matter originating in primary production ends up in one form or another in what is represented in flow diagrams as a box with inscription 'decomposers'. For instance, an analysis of the Serengeti Plains (Phillipson, 1973)...
Together with low cost, the current formulation suggests new space in electrolyte design where nearly all factors that matter to the sustainability of batteries can be well balanced. This is a preview of subscription content, access via your institution Access options Access Nature and 54 other ...
If you're cycling during winter for any length of time, wearing a pair of overshoes over your cycling shoes will offer extra insulation and protection from the elements that should hopefully keep your feet comfortable and warm. If you've had frozen feet on the bike before I'm willing to ...
Start with dynamic stretches to loosen up your muscles and improve flow of blood to the joints. Incorporate movements that mimic the golf swing, such as arm circles, torso twists, and hip rotations. Gradually increase the intensity of your warm-up to elevate your heart rate and prime your ...
open-system anoxic, cold, hypersaline environments like GH, where dormant or dead populations may be present and organic matter including DNA may be preserved [5]. Indeed, detected active microbial communities at AHI springs including Lost Hammer differ from the total microbial biomass [6,28,29]...

comparing O2 consumption (VO2) and CO2 production (VCO2) during a single bout of personalized cycling intensity (~40% VO2max) at sea level (0 m) and at simulated 2000 m altitude, i.e., under normal (N-Ox: 20.9%) and mildly reduced (R-Ox: 17.0%) normobaric oxygen, respectively. ...
deep geothermal energy; thermal cycling treatment; uniaxial compression strength; crack propagation; failure mode1. Introduction Renewable and reliable resources, such as deep geothermal and nuclear energy [1,2], have attracted a large amount of concern for their clean, financial, and environmentally ...
