封闭式行星轮系中功率流的图解法

Jixie chuandong, 2007
Based on the fundamental formulas, the diagrams are derivated and drawn reflecting the relationship between the structure and power flow of closed planetary gear train. They can be applied to analyze existed trains for the power flow direction.

Dynamic Response of Planetary Bearings in a Double Planetary Gear Train with Forward and Reverse Carrier Rotations

Machines
Planetary bearings are critical components in double planetary gear trains. The influence of carrier rotation direction on bearing dynamic behavior remains insufficiently understood, which hinders accurate reliability assessment and optimal design.

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

Journal of Fish Biology, EarlyView.
Abstract Marine fish species are likely to exhibit little genetic differentiation among populations due to their high dispersal potential during early life stages and migratory nature. However, recent studies have increasingly reported intraspecific genetic differentiation resulting from species‐specific ecological traits, environmental factors, and ...

How Alternative Management Ideas Are Realized for the Public Good: Performative Fabrics of Humanistic Practices

Journal of Management Studies, EarlyView.
Abstract Repurposing management for the public good involves realizing alternative ideas to serve societal interests. Humanistic management is centred on such ideas as human dignity and well‐being. Realization refers to the generation and maintenance of social realities corresponding to these ideas.
