Basins of attraction in nonsmooth models of gear rattle [PDF]
, 2008 This paper is concerned with the computation of the basins of attraction of a simple one degree-of-freedom backlash oscillator using cell-to-cell mapping techniques. This analysis is motivated by the modeling of order vibration in geared systems.

Conversational Democracy: Facilitating Children's ‘Unprompted Talk’ in Social Work Dialogues
Child &Family Social Work, EarlyView.ABSTRACT In child and family social work dialogues, social workers address topics that are relevant to children's well‐being and safety. In doing so, they inevitably prioritize one conversational direction over another. This means that while one topic is being addressed, other possible topics are put on hold or are simply never developed.

Solar drum positioner mechanisms [PDF]
, 1982 The need for additional power on spinning satellites required development of deployable solar arrays activated, as on a 3-axis vehicle, after separation from a booster or shuttle orbiter. Mechanisms were developed for telescopically extending a secondary

Fish and Fisheries, EarlyView.ABSTRACT The fishing sector is facing a major crisis, usually addressed from an economic and/or environmental perspective. However, at least in developed countries, the ageing of fishers and the lack of generational replacement is one of the main challenges to its survival. Although the sector has been calling for this problem to be addressed, there is

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)
Fisheries Oceanography, EarlyView.ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Study of lubricant jet flow phenomena in spur gears: Out of mesh condition [PDF]
, 1983 The penetration depth onto the tooth flank of a jet of oil at different velocities pointed at the pitch line on the outgoing side of mesh was determined. The analysis determines the impingement depth for both the gear and the pinion.
