Bioavailable Dissolved Organic Carbon Serves as a Key Regulator of Phosphorus Dynamics in Stream Biofilms. [PDF]

open access: yesEnviron Microbiol Rep
We tested the effect of bioavailable DOC on P entrapment in biofilms and in biofilm P‐regulation mechanisms such as polyphosphate accumulation and alkaline phosphatase activity in semi‐natural experimental flumes. Our results show that intracellular P entrapment is limited by bioavailable DOC, while extracellular P entrapment is independent of ...

Heat treatment of poplar plywood: modifications in physical, mechanical and durability properties

open access: yesiForest - Biogeosciences and Forestry, 2023
Plywood made of poplar are limited to indoor usages since poplar exhibits a rather low natural durability. Recently, wood heat treatments have been applied to improve properties such as decay susceptibility and dimensional stability.

Monitoring and Heat Transfer Modelling of the Cure of Thermoset Composites Processed by Resin Transfer Moulding. [PDF]

open access: yes, 1999
Experimental studies have demonstrated the existence of significant thermal gradients during the cure stage of Resin Transfer Moulding (RTM). Presence of such thermal gradients can affect the final degree-of-cure distribution and cause the development

Impact of magnetic resin on DOC removal and downstream water treatment processes [PDF]

open access: yes, 2008
Seasonal periods of high rainfall and changes in land management have led to difficulties for UK water companies to remove sufficient natural organic matter (NOM) to stay in compliance with the tightening trihalomethane (THMs) standards.
