Synergetic effects for p-nitrophenol abatement using a combined activated carbon adsorption-electrooxidation process

A novel fluidized electrochemical reactor that integrated advanced electrochemical oxidation with activated carbon (AC) fluidization in a single cell was developed to model pollutant p-nitrophenol (PNP) abatement. AC fluidization could enhance COD removal by 22%-30%. In such a combined process, synergetic effects on PNP and COD removal was found, with their removal rate being enhanced by 137.8% and 97.8%, respectively. AC could be electrochemically regen erated and reused, indicating the combined process would be promising for treatment of biorefractory organic pollutants.     

IC反应器快速启动的试验研究

采用麸皮纤维作载体来启动IC反应器可促进厌氧污泥的颗粒化进程,加快IC反应器的启动．试验研究表明,投加麸皮纤维的IC反应器所需启动时间仅为41d,比不投加麸皮纤维的IC反应器提前了20d;投加麸皮纤维的IC反应器最高处理容积负荷是不投加麸皮纤维的IC反应器的1．38倍．

''''97全国甲A足球队春训生化指标的观察

从整个春训期间生化指标中反映,春训的大强度训练计划是合理的,运动员身体机能状况处于正常水平,但大负荷课强度较小,达不到大负荷刺激机体、提高机能水平的目的。训练手段以３对３以下的对抗攻守练习强度较大,如果增加密度,对提高运动员对抗中完成各种技术能力和无氧代谢能力有利。血乳酸是反映运动强度的良好指标,应根据足球训练的特点,选择和增加采血点,才能更准确地反映运动训练的实际情况。     

Stiffness,intralimb coordination,and joint modulation during a continuous vertical jump test

This study analysed the modulation of jump performance, vertical stiffness as well as joint and intralimb coordination throughout a 30-s vertical jump test. Twenty male athletes performed the test on a force plate while undergoing kinematic analysis. Jump height, power output, ground contact time, vertical stiffness, maximum knee and hip flexion angles, and coordination by continuous relative phase (CRP) were analysed. Analysis of variance was used to compare variables within deciles, and t-tests were used to compare CRP data between the initial and final jumps. Results showed reduction in jump height, power output, and vertical stiffness, with an increase in contact time found during the test. Maximum knee and hip flexion angles declined, but hip angle decreased earlier (10–20% of the test) than knee angle (90–100%). No changes were observed in CRP for thigh–leg coupling when comparing initial and final jumps, but the trunk–thigh coupling was more in-phase near the end of the test. We conclude that fatigue causes reduction in jump performance, as well as changes in stiffness and joint angles. Furthermore, changes in intralimb coordination appear at the last 10% of the test, suggesting a neuromotor mechanism to counterbalance the loss of muscle strength.
