BACKGROUND Previous research has shown that cycling in a standing position reduces cycling economy compared with seated cycling. It is unknown whether the cycling intensity moderates the reduction in cycling economy while standing. PURPOSE The aim was to determine whether the negative effect of standing on cycling economy would be decreased at a higher intensity. METHODS Ten cyclists cycled...

Computational modeling of reaction systems can provide a strong foundation for experimental investigations. In this investigation, we first propose a unique theoretical system for breaking chiral symmetry that utilizes thermal cycling to amplify a small initial asymmetry. Unlike models in the literature, no autocatalytic reactions were needed for homochirality in this model to emerge. Following...

BACKGROUND Glass-ionomer cements perform a protective effect on the dentin-pulp complex considering the F ions release and chemical bonding to the dental structures. On the other hand, those materials have poor physic-mechanical properties in comparison with the restorative resin composite. The main aim of this work was to evaluate the influence of zirconia and/or alumina fillers on the microst...

Soil health is a critical determinant of plant performance. This manuscript describes how the physical, chemical, and biological components within soil interact to create good health. structure important provide support for plants, nutrient water cycling, decreased compaction, more efficient carbon storage. Measurements properties are presented that can be done in field on any soil.

Monoelectrochemical Conversions Multielectrochemical phase conversion is usually involved in a fast capacity fading during charge–discharge processes. In article number 2100108 by Minghua Wang, Hanping Zhang, and co-workers, an organic sulfur material [email protected] exhibits monoelectrochemical with enhanced cycling performance. The finding that the chemical matching point electrochemical ar...
