Microplastic Pollution in Aquaculture: Challenges and Mitigation

open access: yesWater and Environment Journal, Volume 40, Issue 1, Page 3-20, February 2026.
ABSTRACT Microplastics (MPs) have gained significant attention due to their potential environmental threat. This paper addresses MPs contamination in aquaculture, a critical concern for food safety and public health. The extensive use and disposal of plastic products in aquaculture, like netting materials, pose a significant threat to aquatic life ...

On the danger of redundancies in some aerospace mechanisms [PDF]

open access: yes
An attempt is made to show that redundancies in some aerospace mechanisms do not generally improve the odds for success. Some of these redundancies may even be the very cause for failure of the system. To illustrate this fallacy, two designs based on the
