Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae

Popular Abstract in Swedish Alla växter utsätts för någon form av stress i sin dagliga miljö. Till exempel råder det väldigt sällan optimala tillväxtförhållanden på en åker, där ogräsen konkurrerar, insekterna knaprar, svamparna frodas och olika näringsbrister kan råda, för att inte tala om de torra somrarna. Det är alltså troligt att en växt utsätts för ett flertal stressfaktorer samtidigt, vilkePlants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. In this work the intera

Time-Domain Theory of Forerunners

The time-domain theory of forerunners (precursors) in temporally dispersive, nonmagnetic, isotropic materials is developed with the propagator technique. Specifically, the impulse response at a (comparatively) large propagation depth is expanded in two different ways: (a) with respect to the wave front and (b) with respect to slowly varying field components. A few numerical examples illustrating t

CLEAR: A novel family of highly cross-linked polymeric supports for solid-phase peptide synthesis

Cross-Linked Ethoxylate Acrylate Resin (CLEAR) supports were prepared by radical copolymerization, either in the bulk or suspension mode, of the branched cross-linker trimethylolpropane ethoxylate (14/3 EO/OH) triacrylate (1) with one or more of allylamine (2), 2-aminoethyl methacrylate·HCl (3), poly(ethylene glycol-400) dimethacrylate (4), poly(ethylene glycol) ethyl ether methacrylate (5), and t

Critical Systemic Thinking – or The Standard Engineer in Paris

In wanting to pursue critically informed research, we highlight a steppingstone we use in our struggle answering the question ‘How do we recognize what to critically reflect upon?’. When we, as researchers, try to apply critical thinking we may find that our descriptions of our reasoning undermine the purpose for those descriptions. We perceive problems to flow from an entrapment of mind in the ‘f
