ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Dynamics of a split torque helicopter transmission [PDF]
A high reduction ratio split torque gear train has been proposed as an alternative to a planetary configuration for the final stage of a helicopter transmission. A split torque design allows a high ratio of power-to-weight for the transmission.

Next Generation Hosts for Protein Recognition, Assembly and More
The original design of synthetic receptors for proteins was based on macrocycles with a hydrophobic core and a polar/charged periphery. This design, geared towards protein recognition, facilitates receptor self‐assembly. Macrocycle oligomerization, in turn, contributes to protein assembly as evidenced in many cocrystal structures.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Fatigue Life Analysis of the Plastic Helical Gear and Steel Worm Transmission Mechanism
The rapid development of polymer materials has promoted the trend of plasticization of metal gears in medium and low load gear transmissions. Plastic helical gears are often used to replace metal worm gears in the worm and helical gear transmission, but ...
