Analysis of Influence Factor of Oil Jet Lubrication Impingement Depth of Aviation Spur Gear

Jixie chuandong, 2017
When the nozzle is decorated without offset and incline,gears with transmission ratios above 1 won’t be efficiently lubricated. In order to solve this problem,analytic method is adopted to establish mathematical model,basing on the geometric relationship

Den attendance by Arctic foxes experiencing 10 years of increasing tourism

Wildlife Biology, EarlyView.
Wildlife tourism is a growing industry, and an increasing number of people seek to observe and interact with wild animals in their natural surroundings. In Iceland, the native Arctic fox Vulpes lagopus is widespread and has been under heavy hunting pressure for centuries.

Forty years of captive breeding in Przewalski's horse: pedigree‐based insights into population growth, sex ratio, and inbreeding

Wildlife Biology, EarlyView.
Long‐term captive breeding programs play a critical role in the conservation and reintroduction of endangered species, yet they face persistent challenges related to demographic structure and genetic management. The Przewalski's horse Equus przewalskii, once extinct in the wild, represents a global model for conservation breeding supported by pedigree ...

Profile modification to minimize spur gear dynamic loading [PDF]

An analytical computer simulation program for dynamic modeling of low-contact-ratio spur gear systems is presented. The procedure computes the static transmission error of the gears operating under load and uses a fast Fourier transform to generate the ...

Collaborating in future states—Contextual instability, paradigmatic remaking, and public policy

Australian Journal of Public Administration, EarlyView.
Abstract Collaboration is ubiquitous in public policy life, with its presence and profile determined by prevailing governance conditions. Commitments to globalisation and marketisation in the latter part of the 20th century marked the onset of an era defined by collaboration, between and across tiers and spheres of government, with non‐state actors ...

Crisis, temporality and governmental policy agendas: The cases of Finland and Sweden

Scandinavian Political Studies, EarlyView.
Abstract Crises transform the temporal orientation of political decision‐making. They demand immediate and decisive action and thus convert time into a means of political control. In these circumstances, assessing the long‐term consequences of proposed policies with respect to welfare, sustainability or justice also becomes demanding.

The company you keep: becoming one(self) in an Indonesian convent En bonne compagnie : devenir (quelqu’)un dans un couvent indonésien Pergaulan dalam biara di Indonesia: sebuah proses pembentukan diri*

Journal of the Royal Anthropological Institute, EarlyView.
This article investigates companionate processes of self‐making in a religious community of Catholic nuns in eastern Indonesia. I argue that the sociality of the convent establishes a unique context for understanding the effects of one's company on processes of self‐becoming.
