Sustainable Development, EarlyView.ABSTRACT Isolating environmental issues from their broader social and political context limits understanding of their true drivers. In this sense, factors such as governance and education can be powerful determinants of environmental performance. This research examines the factors influencing the Environmental Health component of the Environmental ...

µPIV Measurement of Grease Velocity Profiles
, 2013 Lubricating grease is commonly applied to lubricate e.g. rolling bearings, seals and gears. Grease has some clear advantages over lubricating oil. It is a semi-solid material, which prevents it from flowing/leaking out from the lubricated system and ...

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction
steel research international, EarlyView.Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Symbolic Interaction, EarlyView.In this paper, we use Goffman's notion of “face work” to examine how pipeline engineers perform and present their working selves as competent experts. Our analysis identifies various faces and face work tactics, including a focus on professional judgment, actively selling one's expertise relative to others, protective self‐deprecatory strategies, and ...

Understanding grease flow through optical visualizations
, 2012 The flow dynamics of a lubrication mechanism is very complex, much due to the complex rheology and composition of the grease. In order to obtain an optimal lubrication, both the initial amount of grease and the position of the grease is highly important ...

An Outline of a Theory of Play
Symbolic Interaction, EarlyView.Play is often dismissed as trivial, yet it is a fundamental and adaptive aspect of human and mammalian life. This paper develops a sociological theory of play, treating it as a total social fact that spans biological, psychological, and social dimensions.
