Model Experiments on the Sardine Purse Seine Operating in Hyuganada-IV

open access: yesNIPPON SUISAN GAKKAISHI, 1954
As the fourth step in the experimental studies of the purse seine, a series of model experiments was made with the purpose of investigating the timely change of the depth of bottom margin of the net in the course of operation. The model gear and the experimental apparatus were the same as were used in the previous experiments1, 2).

Seabird bycatch in a sardine purse seine fishery

open access: yesICES Journal of Marine Science, 2020
Abstract Limited understanding of seabird bycatch in purse seine fisheries has been highlighted as a key information gap in assessments of seabird bycatch in fisheries globally. This study documents the bycatch of breeding flesh-footed shearwaters (Ardenna carneipes) in a sardine purse seine fishery on the southern coast of Western ...

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Feeding Habits of Mene maculata (Teleostei: Menidae) in the Southwestern Waters of Taiwan, Western Pacific Ocean

open access: yesFishes
This study investigated the feeding habits of moonfish (Mene maculata) in the waters of southwestern Taiwan in the Western Pacific Ocean using commercial trawling nets and Taiwanese purse seines. For this, we analyzed the body size and stomach content of

An Analysis on the Sinking Resistance of Purse Seine - 2. In the Case of the Model Purse Seine with Different Netting Material and Sinkers -

open access: yesBulletin of the Korean society of Fisheries Technology, 2004
This study deals with an analysis on the sinking resistance for the model purse seine, in the case of different netting material and sinkers. The experiment was carried out using rune simplified model seines of knotless nettings. Dimension of model seines 420cm for corkline and 85cm for seine depth, three groups of models rigged 25, 45 and 60g with the

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

open access: yesAdvanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

open access: yesAdvanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...
