Analysis of Dynamics Characteristic of the Helical Gear Transmission in Helicopter

Jixie chuandong, 2015
The multiaxial helical gear transmission is widely used in helicopter for parallel operation. The dynamics model of the helical gear transmission is established for system inherent characteristic analysis,and the dynamic response is obtained.

Spontaneous unidirectional rotation of a symmetric gear driven by spherical active particles

National Science Open
Time reversal asymmetry and spatial anisotropy are considered two prerequisites for Brownian ratchet. An intriguing realization can be achieved by placing an asymmetric gear in the suspension of motile rod-like bacteria.

Reshaping Labor Intermediation: An Integrated Workforce Management Strategy to Contrast Agricultural Workers' Exploitation in Italy

Strategic Change, EarlyView.
ABSTRACT Labor exploitation within agri‐food supply chains poses significant ethical and managerial challenges, particularly in Mediterranean contexts where irregular employment practices persist. This study investigates the case of NoCap, a third‐party ethical certification initiative operating in Italy that integrates social responsibility into ...

INVESTIGATION OF GEARS WITH ASYMMETRIC PROFILE USING RELIABILITY PARAMETERS

Ukrainian Journal of Mechanical Engineering and Materials Science
The results of the study of gears with involute and sinusoidal teeth are presented herein. The subjects of the comparative analysis were the stresses at the root of the tooth from the side of the applied load and from the side of the unloaded profile, contact stresses, and elastic deformations under the action of a given torque.

C‐LENS: An Integrative Process Framework for Managing Governance and Complexity in University–Industry Collaboration

Knowledge and Process Management, EarlyView.
ABSTRACT University–industry collaboration (UIC) often underperforms not because its relevance is unclear, but because collaboration processes are rarely designed to accommodate evolving governance needs amid complexity. Existing studies have examined drivers, barriers, and institutional interfaces, yet process dynamics, governance mechanisms, and ...

Parametric Modeling and Contact Stress Analysis of Asymmetric Modified Helical Gears

Jixie chuandong
In order to construct an accurate model of asymmetric involute modified helical gears and analyze the influence of pressure angles on its contact stress, based on the gear meshing principle and the secondary development of SolidWorks in C#, a ...

Should Paratonia Be Considered a Movement Disorder? Implications for Clinical Management

Movement Disorders Clinical Practice, EarlyView.
Abstract Paratonia is an involuntary and variable resistance to passive movement that emerges with cognitive decline in dementias of different etiologies, with prevalence approaching 90% to 100% in end‐stage disease. It is common in Parkinson disease and the atypical parkinsonisms.

Defining equity: Government and community notions of equity in marine conservation co‐management

People and Nature, EarlyView.
Abstract Perceived inequities lie at the core of many conservation conflicts, yet empirical comparisons of how different stakeholders conceptualise equity remain rare. Despite its prominence in global policy frameworks, equity is context‐dependent and understood differently by different actors, making it difficult to define and operationalise. Using an

Computational analysis of the effect of bogie inclination angle on landing gear noise

, 2010
Airframe noise and in particular main landing gear noise is a major noise source during the approach phase. Wind tunnel tests have shown a strong relationship between the inclination angle of the bogie and the noise radiation of a main landing gear ...

Forest governance and the politics of care: Practices, subjectivities and more‐than‐human‐relations in contemporary conservation regimes in Guaviare, Colombia

People and Nature, EarlyView.
Abstract Market‐based conservation instruments such as REDD+ and Payments for Ecosystem Services (PES) have been promoted to curb deforestation in the Colombian Amazon. Yet these schemes remain contested, as they advance neoliberal conservation and reproduce gender inequalities.
