This paper presents the first 3-axis MEMS gyroscope that employs intermittent free vibration realized by a "Catch-and-Release (CR)" method. While CR enables drive power reduction and instant start-up, its application to multi-axis tuning-fork (TF ...

“Catch-and-Release” of HNO with Pyrazolones
The Journal of Organic Chemistry, 2015A new and versatile class of HNO donors, the (hydroxylamino)pyrazolone (HAPY) series of HNO donors utilizing pyrazolone (PY) leaving groups, is described. HNO, the smallest N-based aldehyde equivalent, is used as a reagent along with a variety of PY compounds to synthesize the desired HAPY donors in what can be considered an N-selective HNO-aldol ...

Ionic catch and release oligosaccharide synthesis (ICROS)
Chemical Communications, 2011A general and efficient chromatography-free ionic-liquid-supported "catch-and-release" strategy for oligosaccharide synthesis (ICROS) is reported. The methodology is compatible with current glycosylation strategies and amenable to protecting group manipulations. A series of β-(1→6) and β-(1→2)-linked glycan structures have been prepared to showcase the

Catch-and-release regulations and paddlefish angler preferences
Journal of Environmental Management, 2018This paper presents research on recreational paddlefish anglers' preferences for catch-and-release fishing. We used stated preference (SP) data from a choice experiment to identify the effect of a hypothetical catch-and-release regulation on fishing preferences, and revealed preference (RP) data to measure the desirability of actual paddlefish fishing ...

Catch and Release in Marine Recreational Fisheries
2002<em> Abstract.</em>—This study evaluates the performance of circle and comparable-size “J” hooks on Atlantic and Pacific sailfish <em> Istiophorus platypterus </em>and, to a lesser extent, on Pacific blue marlin <em> Makaira nigricans</em>.

From Catch-and-Harvest to Catch-and-Release: Multimodality and Deinstitutionalization
Academy of Management Proceedings, 2019In this paper, we join research on deinstitutionalization with the multimodal turn in organization studies to explore how organizations can use visual and material artifacts to assault longstanding practices. We adopt an interpretive approach using magazine cover images to explore the deinstitutionalization of catch-and-harvest fly fishing practices in

Noncovalent Catch and Release of Carboxylates in Water
The Journal of Organic Chemistry, 2014Association constants of a bis-(acetylguanidinium)ferrocene dication to various (di)carboxylates were determined through UV-vis titrations. Association constant values greater than 10(4) M(-1) were determined for both phthalate and maleate carboxylates to the bis-(acetylguanidinium)ferrocene salt in pure water. Density functional theory computations of

RADIOCHEMISTS can now expand their toolbox of molecular probes for positron emission tomography (PET), thanks to a new electrophilic fluorinating reagent. The palladium-based compound is made with 18F-fluoride, rather than 18F-fluorine gas, so it’s more practical to prepare than previously reported electrophilic fluorinating agents ( Science, DOI: 10 ...

Linking Angling Catch Rates and Fish Learning under Catch-and-Release Regulations
North American Journal of Fisheries Management, 2006Abstract Many recreational fisheries are subject to varying degrees of catch-and-release fishing through regulations and conservation-minded anglers. Clearly, releasing a proportion of the catch improves conservation of the fishery, yet it is not clear how the released catch contributes to angling quality.

Fisheries Management and Ecology
The impact of recreational fisheries on marine ecosystems is often overshadowed by commercial fisheries, although recreational fishing harvest can be substantial, especially for species that are either overfished or experiencing overfishing.
