Eggs in the freezer: energetic consequences of nest site and nest design in Arctic breeding shorebirds [PDF]
, 2012 Birds construct nests for several reasons. For species that breed in the Arctic, the insulative properties of nests are very important. Incubation is costly there and due to an increasing surface to volume ratio, more so in smaller species. Small species

Development of High Efficiency Dog Clutch with One-Way Mechanism for Stepped Automatic Transmissions
International Journal of Automotive Engineering, 2019 In order to reduce drag losses and a clutch actuator load, the new dog clutch system for stepped automatic transmission is developed. Transmitting torque is converted to the engaging force because rotating shaft and dog clutch are connected with the ...
