Eco‐Innovation Among Environmental Small and Medium Enterprises: A Complexity Theory View on a Regional Paradox

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Environmental entrepreneurship and eco‐innovation, although cornerstones in the transition to a sustainable world, form a research nexus that remains largely understudied. We draw on the theory of complexity and the notion of cultural, temporal, and relational complexities to explain the process of eco‐innovation among environmental small ...

Noise and Vibration Analysis of Electric Oil Pump with Asymmetric Pitch Control for Gearbox in Hybrid and Battery Electric Vehicle

open access: yesApplied Sciences
This study proposes an asymmetric pitch control technique for electric oil pumps with symmetric gear-type pumps in order to reduce noise and vibration. For vane pump noise reduction, mechanical asymmetric pitch arrangements of each vane are widely used ...

Automatic Scallion Seedling Feeding Mechanism with an Asymmetrical High-order Transmission Gear Train

open access: yesChinese Journal of Mechanical Engineering, 2020
The current automatic scallion-transplanting machine is a complicated mechanism composed of two linkage mechanisms and two band carriers. It delivers seedlings inefficiently because of the movement limitations of the linkage mechanism.

Ni2‐Imido Bispincer Platforms: Cooperative Reactivity Enabled Through Substrate Addition Across a Ni2N Unit

open access: yesChemistry – A European Journal, EarlyView.
Ni2 bispincer complexes with an embedded central imido anchor are presented. The bispincer complexes leverage the high basicity of imido ligands to facilitate 1,2 addition of weak B─H and Si─H bonds, resulting in hydrido–amido complexes and resultingly a contortion of a Ni─Ni sigma bond to form an S = 1 species. The 1,2 addition is proposed to serve as

An analysis of fishing gear competition. Catalan fisheries as case studies

open access: yesScientia Marina, 2013
An asymmetric index was developed to measure the competition relationships among fishing fleets (or gears or métiers) in a multispecies fishery. This index can be used to measure the degree of dominance of each fleet and its level of independence from ...
