The metabolic cost of producing joint moments is greater at the hip than the ankle.

Older adults walk using their hips relatively more and their ankles relatively less than young adults. This "distal-to-proximal redistribution" in leg joint mechanics is thought to drive the age-related increase in metabolic rate during walking. However, many morphological differences between hip and ankle joints make it difficult to predict how - or if - the distal-to-proximal redistribution affects metabolic rate during walking.

Kinetic study on the degradation of Acid Red 88 azo dye in a constructed wetland-microbial fuel cell inoculated with Shewanella oneidensis MR-1.

Removal of Acid Red 88 (AR88) as an azo dye from the synthetic type of wastewater was studied in a laboratory-made constructed wetland microbial fuel cell (CW-MFC) inoculated with Shewanella oneidensis MR-1 (SOMR-1). Plant cultivation was implemented using a typical CW plant known as Cyperus alternifolius. The complexity of the SOMR-1 cell membrane having different carriers of electrons and H ions gives the microbe special enzymatic ability to participate in the AR88 oxidation link to the O reduction.

Mindfulness and Procrastination Among University EFL Learners: The Role of Attention Control and Self-Regulated Learning.

The present study aimed to investigate the interconnections among mindfulness, self-regulated learning (SRL), attention control, and procrastination among English as a foreign language (EFL) learner in Iran. Additionally, the mediating influence of SRL and attention control on mindfulness-procrastination link were tested. For this purpose, 272 university EFL students were conveniently selected and administered self-report questionnaires.

Carbon-Based Materials in Combined Adsorption/Ozonation for Indigo Dye Decolorization in Constrain Contact Time.

This study presents a comprehensive evaluation of catalytic ozonation as an effective strategy for indigo dye bleaching, particularly examining the performance of four carbon-based catalysts, activated carbon (AC), multi-walled carbon nanotubes (MWCNT), graphitic carbon nitride (g-CN), and thermally etched nanosheets (CN-TE). The study investigates the efficiency of catalytic ozonation in degrading Potassium indigotrisulfonate (ITS) dye within the constraints of short contact times, aiming to simulate real-world industrial wastewater treatment conditions. The results reveal that all catalysts demonstrated remarkable decolorization efficiency, with over 99% of indigo dye removed within just 120 s of mixing time.
