Lipid quality during frozen storage of the low trophic marine resource polychaete (Alitta virens) was evaluated after blanching, vacuum packing, and different storage temperatures (−23°C vs −27°C). In non-blanched samples, free fatty acid (FAA) reached a level of 15–20% after 12-months of frozen...
The possibility to produce multi-materials and functionally graded materials opens new opportunities within material development, not only to explore new possibilities for combinations of different materials, but also to develop entirely new materials. Materials that are customized for individual...
Duplex stainless steels are widely used in offshore oil and gas, maritime, process, and nuclear industries as they deliver high corrosion resistance, toughness, and ductility, but they are sensitive to formation of brittle microstructures during additive manufacturing. This study has explored the...
Four hot-gas bypass defrosting configurations for CO2-NH3 cascade blast freezer for application in fish processing firm are numerically investigated. Due to the high moisture content of fish, defrosting is necessary after every 4 to 5 h of batch operation. A thermodynamic model for the cascade...
Sand casting usually implies some flash or burr on the cast parts that are unevenly distributed and variations in size and mass. Furthermore, the cast part itself can also have significant geometric deviations caused by sand casting process variations. Effective automated deburring needs to be fast...
Abandoned, lost, or otherwise discarded fishing gear (ALDFG) is a global challenge that negatively affects marine environment through plastic pollution and continued capture of marine animals, so-called “ghost fishing”. In different pot fisheries, ghost fishing related to ALDFG is of concern...
Glass industries contribute approximately 22 million tonnes of CO2 emissions in Europe annually. The European Clean Hydrogen Alliance has developed an investment agenda to support the strategic investment of hydrogen amounting to 9.3 billion €. Hydrogen is a potential fuel source but is not readily...
The holy grail of Industry 5.0 resides in the intersection of the three dimensions; sustainable, resilient, and human-centric manufacturing. While the Industry 4.0 paradigm addresses resiliency and sustainability through increased flexibility and efficiency, the human component of manufacturing...
Synthetic oil spill dispersants have become essential in offshore oil spill response strategies. However, their use raises significant concerns regarding toxicity to phyto- and zooplankton and other marine organisms, especially in isolated and vulnerable areas such as the Arctic and shorelines...
In the Asian paddle crab (Charybdis japonica) gillnet fishery in the Yellow Sea, China, the minimum mesh size (MMS) regulation has been of a major importance due to high bycatch rates of undersized crabs. In this study, we evaluated how gillnet mesh size can affect the capture probability of C...
