Tidal hydroelectric power has been proposed as one potential solution for sustainable energy sources. The first tidal turbine in North America began continuous operation in the Annapolis River estuary (44 °45'N; 65° 29'W) in June, 1985. The machine

Co-extruded films with up to 65 layers of two rheologically mismatched polymer systems – polystyrene/poly(methylmethacrylate) (PS/PMMA) and hard/soft thermoplastic polyurethanes (TPUs) – were successfully produced using a combination of a 9-layer

This research work presents the first continuous multilayer coextrusion system for high viscosity elastomeric materials. Three unvulcanized rubber materials were chosen to validate the system: two butyl rubbers and a polyisoprene. The elastomers were

A new extensional rheometer limited in achievable strain only by sample rupture is presented. The rheometer is based on the Meissner design of two pairs of counter-rotating rollers pulling a sample of fixed length but is small enough to fit inside th

Two dies for polymer co-extrusion layer multiplication are evaluated experimentally and computationally in terms of pressure drop and layer uniformity. The first design is that of the original die, is compact, and has successfully been used to co-ext

The snapper-grouper fishery off the coast of the southeastern United States contains many exploited species that are governed under a multitude of species-specific regulations. Despite ample information on landed commercial catches, there is a critic

The blueline tilefish Caulolatilus microps is a long-lived, slow-growing deepwater demersal species patchily distributed along the outer continental shelf of North America from Cape Lookout, North Carolina, to Campeche Bank, Mexico. Commercial landin

Juvenile king mackerel Scomberomorus cavalla and Spanish mackerel S. maculatus are caught by commercial shrimp trawlers in South Carolina. Our study documented the extent and duration of this bycatch during the commercial shrimp trawling season in So

We investigated whether the abundance of age-0 mackerels in a fishery-independent trawl survey could be used to predict abundance at age 1 for king mackerel Scomberomorus cavalla and Spanish mackerel S. maculatus. After deletion of inappropriate leng
