Interfaces in Self-Assembling Diblock Copolymer Systems: Characterization of Poly(isoprene-b-methyl methacrylate) Micelles in Acetonitrile

The kinetics of dipolar nonradiative energy transfer (DET) between dyes confined to the core−corona interface region of poly(isoprene-b-methyl methacrylate) block copolymers (PI−PMMA) in acetonitrile was analyzed using a new distribution model for energy transfer in spherical micelles. The distribution of block junction points was described by the model of Helfand and Tagami (HT) for the strong se

A visual self-image of legal authority: 'The temple of law'

The focus of this article is on the legal profession's visual self-image of legal authority. It takes a departure from the themes of visual legal communication and discusses the relationship between text and pictures in the legal domain. The discussion concludes with a reflection on the consequences of the modern pictorial evolution. Bearing this discussion in mind, will the development of the ICT

Six-band k center dot p calculation of spin-dependent interband tunneling in strained broken-gap heterostructures under a quantizing magnetic field

We investigate spin-dependent interband magnetotunneling processes in strained broken-gap resonant tunneling structures made from InAs, AlSb, and GaSb, which are promising materials for quantum devices. InAs/AlSb/GaSb/InAs/AlSb/GaSb double-barrier structures grown on both InAs and GaSb are considered. Transmission coefficients for interband tunneling processes from individual eigenstates in the In

Renal function in the setting of urinary diversion

Incorporating bowel into the urinary tract sets the stage for a potentially dangerous situation for the upper part of this tract. Obstruction, reflux and chronic bacteriuria may develop, all of which can all be detrimental. Most reports on renal function have used IVP and serum creatinine only, methods which are inadequate for proper assessment. Long-term follow-up of patients with ileal conduit d

Försäkringskassans frågor till rehabiliteringsaktörer.

Försäkringskassans handläggare ska avgöra om en individ kan utföra sina arbetsuppgifter eller är i behov av stödåtgärder för att klara sitt arbete. Handläggarna behöver information om i vilken grad sjukdomen eller skadan påverkar funktionsförmågan och möjligheten till arbetsåtergång. De upplever dock ofta att det medicinska underlaget de har tillgång till i form av läkarintyg är ofullständigt. När

Non-reflecting dispersive media

The modeling of non-reflecting one-dimensional dispersive media is discussed. The media are temporal dispersive with a spatially varying impedance. It is shown that the effects from the variation of the impedance can be matched by the temporal dispersive effects so that the media do not reflect any field regardless of the shape of the incident transient field. The problem of finding reflectionless

Receptor-mediated uterine effects of oxytocin and vasopressin

The neurohypophyseal hormones oxytocin and vasopressin are important in the regulation of uterine contractility. These hormones, as well as prostaglandin F2α, are most forceful myometrial tissue contractors. Vasopressin is probably a causative factor in primary dysmenorrhoea, whereas oxytocin is the major uterine stimulator of labour, both at term and preterm. In a prospective study we investiga

Extrachromosomal RNA-DNA complex containing long telomeric repeats in chironomids.

We have analysed an extracted RNase sensitive fraction containing telomeric repeat sequences in the telomerase negative dipteran Chironomus tentans. It shows a slow and well-defined electophoretic migration corresponding to > 20 kb and is sensitive not only to RNase, but also to DNase. It hybridizes to both strands of the telomeric repeat with about equal intensities. DNA is probably the dominant

Sensory ecology of feeding in the hummingbird hawkmoth Macroglossum stellatarum (Lepidoptera : Sphingidae)

The European hummingbird hawkmoth, Macroglossum stellatarum (Linnaeus 1758), drinks nectar while hovering in front of flowers of all colours, odours, sizes and shapes. Naive moths orient predominantly towards visual stimuli and prefer blue flowers with a radial pattern and a central contrasting spot. Hummingbird hawkmoths have trichromatic colour vision and can learn any colour and different patte

Antimicrobial activity of histidine-rich peptides is dependent on acidic conditions.

Synthetic peptides composed of multiples of the consensus heparin-binding Cardin and Weintraub sequences AKKARA and ARKKAAKA are antimicrobial. Replacement of lysine and arginine by histidine in these peptides completely abrogates their antimicrobial and heparin-binding activities at neutral pH. However, the antibacterial activity against Gram-negative (Escherichia coli, Pseudomonas aeruginosa) an

Few electron double quantum dots in InAs/InP nanowire heterostructures

We report on fabrication of double quantum dots in catalytically grown InAs/InP nanowire heterostructures. In the few-electron regime, starting with both dots empty, our low-temperature transport measurements reveal a clear shell structure for sequential charging of the larger of the two dots with up to 12 electrons. The resonant current through the double dot is found to depend on the orbital cou
