Abstract Dive studies across mammals, birds, reptiles and fish often focus on deep dives, shallow water diving has tended to be overlooked. For air-breathers, foraging in poses challenges since the lungs generate buoyancy, divers must trade off extent of inhalation against negative buoyancy needed avoid floating surface. Using high-resolution depth loggers, we addressed this knowledge gap aroun...

This article discusses the selection of operating modes for high voltage power supply electrostatic dust collector. Methods generation, regulation in converters and choice converter operation mode are considered.

It has been challenging to achieve multi-photochromic systems without affecting the individual photoswitching properties of constituent units. Herein, we present design and synthesis a new family platinum-acetylide dendrimers containing up twenty-one photochromic dithienylethene (DTE) units that exhibit both high efficiency switching properties. Upon irradiation with ultraviolet (UV) visible (v...
