Effects of Dietary Green Rooibos on Physical Endurance in Swimming Mice

Green rooibos made from unfermented rooibos leaves contains high amounts of aspalathin. Dietary green rooibos is expected to increase physical endurance and decrease physical fatigue, because aspalathin has antioxidant activity and stimulates glucose uptake in muscle tissue. The aim of this study was to validate the effects of green rooibos and aspalathin by using a swimming mouse model. Dietary green rooibos and aspalathin tended to increase swimming time in mice. This beneficial effect might be induced by increased glycogen accumulation in the liver and skeletal muscles.

氩气泡对浸入式水口附近弯月面影响的水模试验

为弄清楚浸入式水口附近钢液弯月面的行为规律，本文进行了水模试验弯月面被沿浸入式水口上升的大的氩气泡所影响。水、硅油和空气用于模型代替钢液、保护渣和氩气，圆柱形棒当做浸入式水口。通过调整具防水涂层圆柱形棒，使水与圆棒的润湿角和钢液与浸入式水口的润湿角相近。一定体积的单个气泡通过罩形容器释放到圆棒底部，用高速摄像机观察了气泡通过水与硅油界面处时硅油在水槽内的聚集行为。
