The amount of dissolved iron in food cooked in Chinese iron pots and that in food cooked in aluminum. stainless steel. and clay pots were determined. It was found that the amount of dissolved iron in food cooked in Chinese iron pots was two to five times higher than that in food cooked in the other types of pots. According to the test results, the estimated increase in daily iron intake was about 14.5 mg for adults and 7.4 mg for children when Chinese iron pots were used. (c) 1990 Academic Press. Inc.

Supernumerary robotic arms(Superlimb) are a new type of wearable robot that works closely with humans as a third hand to augment human operation capability. Accurate conveyance of wearers' intentions, allocation of roles, and humancentered interaction considerations are the key points in the process of human–Superlimb collaboration. This paper proposes a human-centered intention-guided leader–follower controller that relies on the dynamic modeling of Superlimb with application to load-carrying scenarios. The proposed leader–follower controller takes the human as the leader and the Superlimb as the follower, achieving effective information communication, autonomous coordination, and good force compliance between Superlimb, humans, and the environment under human safety assurance. First, the human–Superlimb dynamic system is modeled to achieve force interaction with the environment and wearer. Second, to achieve the precise intention extraction of humans, pose data from five visual odometry sensors are fused to capture the human state, the generalized position, the velocity of hands, and the surface electromyography signals from two myoelectric bracelets sensors are processed to recognize the natural hand gestures during load-carrying scenarios by a designed Swin transformer network. Then, based on the real-time distance detection between human and mechanical limbs, the security assurance and force-compliant interaction of the human–Superlimb system are realized. Finally, the human hand muscle intention recognition, human–robot safety strategy verification,and comparative load-carrying experiments with and without the proposed method are conducted on the Superlimb *** showed that the task parameters are well estimated to produce more reasonable planning trajectories, and Superlimb could well understand the wearer's intentions to switch different Superlimb actions. The proposed sensor-based human–robot communication framework motivates future studies of o

道路问题关乎党的命脉,关乎国家前途、民族命运、人民幸福。实现"两个一百年"的奋斗目标和中华民族伟大复兴的"中国梦"必须坚持走中国特色社会主义道路,而不是什么其他道路。中国共产党对中国特色社会主义道路的高度自信和自觉坚持使我们有必要追问这一道路自信来自何处、基础何在这一前提性问题。我们认为中国特色社会主义道路自信来自于:对人类社会发展前景的积极探索,对当今世界时代主题的科学判定,对过去历史经验教训的深刻总结,对当代中国基本国情的准确把握,新时期以来发展成就的实践证明,对发展中的问题持有的清醒认知。
