ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

A study on the design of asymmetric gears for application in gear pumps
This thesis presents a study on the design of spur gears with asymmetric teeth in external gear pump applications. A model is generated for asymmetric gears and for the specified gear pairs, Hertz contact stresses are determined by using analytical approach. The instantaneous flowrate equation is also derived.

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 ...

Reduction of contact stresses using involute gears with asymmetric teeth [PDF]
Asymmetrical involute gears have a different value of the operating pressure angle for right and left side of the gear. These teeth are suitable for one direction of rotation. Such teeth enable to change the length of the generating line.

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 ...

Toward Highest Frequency, Phase‐Sensitive Electric Field Sensing Enabled by Plasmonic Circuits
An electromagnetic field sensor using an optical sensor head for distortion‐free, high‐sensitivity measurements with potential for high‐frequency operation is presented. The frequency response is enabled by an antenna‐integrated plasmonic modulator. The sensitivity is calculated, and optimizations to obtain thermal‐background‐limited sensitivity are ...

Rigorous Electromagnetic Quasinormal‐Mode Method Made Easy for Users
We present a method that combines numerical techniques with accurate approximations to enable simple and ultrafast computations of the scattered field based on quasinormal modes expansions. The method is made available in the open‐source package MANlite implemented within COMSOL.

Analysis of Dynamics Characteristic of the Helical Gear Transmission in Helicopter
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
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.
