Impact of management scenarios and fishing gear selectivity on the potential economic gains from Namibian hake [PDF]

open access: yes, 1999
This paper develops a model for Namibian hake, which incorporates the biology, gear selectivity and the economies of the hake fisheries in a framework that allows the analysis of fishing gear impacts on the potential economic gains from the resource. The

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

‘Pre‐Technologies’ and the Lifeworld: Assistive Technologies as ‘Pre‐Technologies’ for Self‐Formation as Freedom

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT This article identifies assistive technologies (ATs) as ‘pre‐technologies’ mediating access to other technologies for disabled subjects (DSs). The motivation is to show that without ATs, DSs cannot be said to have the same level of access to freedom and self‐forming activities as able‐bodied subjects.
