Toxic temperatures: Bee behaviours exhibit divergent pesticide toxicity relationships with warming

Global Change Biology, 2023
AbstractClimate change and agricultural intensification are exposing insect pollinators to temperature extremes and increasing pesticide usage. Yet, we lack good quantification of how temperature modulates the sublethal effects of pesticides on behaviours vital for fitness and pollination performance. Consequently, we are uncertain if warming decreases

Tailoring a cognitive behavioural model for unexplained physical symptoms to patient's perspective: a bottem-up approach. [PDF]

, 2010
The prevalence of unexplained physical symptoms (UPS) in primary care is at least 33%. Cognitive behavioural therapy has shown to be effective. Within cognitive behavioural therapy, three models can be distinguished: reattribution model, coping model and

The Behaviour of Toxic Metals in The Brewing Process. [PDF]

Kvasny Prumysl, 2009
Treating hops with a high dose of pesticides containing Cu and Al results in a very slight increase of their content in beer (only by a few hundredths or thousandths of mg/l). The distribution of selected toxic metals (Cd, Pb, Ni, Cr, Hg, As and Se) into beer and brewing residuals (spent grain, trub and yeast) was observed in pilot plant scale ...

Wood-Based Cellulose Nanofibrils: Haemocompatibility and Impact on the Development and Behaviour of Drosophila melanogaster

Biomolecules, 2019
Wood-based cellulose nanofibrils (CNF) offer an excellent scaffold for drug-delivery formulation development. However, toxicity and haemocompatibility of the drug carrier is always an important issue.

Cobalt toxicity in anaerobic granular sludge: influence of chemical speciation [PDF]

, 2008
The influence of cobalt speciation on the toxicity of cobalt to methylotrophic methanogenesis in anaerobic granular sludge was investigated. The cobalt speciation was studied with three different media that contained varying concentrations of complexing ...
