Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

Water quality, fishing effort and fish yield in lakes

Fisheries Research, 1992
The relationship between fish yield, water quality and fishing effort was explored in 70 Finnish lakes. The total yield (kg ha−1 yr−1) was also split to species level (11 species). Fishing effort was estimated by the number of fishermen (fishermen km−2). The principal components of water quality variables were extracted.

Fishing Mortality and Effort

1993
It is convenient to distinguish three problems which involve the variation of the fishing mortality coefficient with age. The first (§8.1.1), concerns the effects of the selective action of the meshes of the fishing gear, and of the interaction between this and recruitment to the exploited area.

Impact of wind speed on fishing effort

Modeling Earth Systems and Environment, 2020
In this work, we search to show the influence of the wind speed on the annual fishing effort, catches and profit of seiners, and show that these parameters are the most important parameters involved in seiner’s fishing activity. To achieve this objective, we consider a bioeconomic system of marine populations exploited, in the southern Atlantic zone of

How commercial fishing effort is managed

Fish and Fisheries, 2018
AbstractWild capture fisheries produce 90 million tonnes of food each year and have the potential to provide sustainable livelihoods for nearly 40 million people around the world (http://www.fao.org/3/a-i5555e.pdf). After decades of overfishing since industrialization, many global fish stocks have recovered, a change brought about through effective ...
