Development of Rotary-type High Speed Puddling Harrow

Experimental Modeling of a Long Orifice-type Restrictor of High Speed Turbine Hybrid Bearing

To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of ...

High-speed atomic force microscopy of protein dynamics: myosin on actin and rotary enzyme F1-ATPase

AFM allows the visualization of biological samples under physiological solution conditions, at high spatial resolution. However, captured images are limited to snapshots because it takes at least 30 seconds to capture an image, whereas biological phenomena are highly dynamic. To overcome this limitation, my group has developed high-speed AFM. The dynamic processes and structural dynamics of pro...

High-speed atomic force microscopy reveals rotary catalysis of rotorless F₁-ATPase.

F(1) is an adenosine triphosphate (ATP)-driven motor in which three torque-generating β subunits in the α(3)β(3) stator ring sequentially undergo conformational changes upon ATP hydrolysis to rotate the central shaft γ unidirectionally. Although extensive experimental and theoretical work has been done, the structural basis of cooperative torque generation to realize the unidirectional rotation...

Resource Specialization in Puddling Lepidoptera

Lepidoptera feed at mud puddles, dung, and carrion in a behavior known as puddling. Sodium and sometimes protein are feeding cues, are actively collected, and play a potentially important role in lepidopteran nutritional and mating ecology. We showed that montane butterßy species have feeding preferences among mud, herbivore dung, and carnivore dung, and that these preferences differed among bu...
