By measuring excited state and charge dynamics in blends of an alternating polyfluorene copolymer and fullerene derivative over nine orders in time and two orders in light intensity, we have monitored the light-induced processes from ultrafast charge photogeneration to much slower decay of charges by recombination. We find that at low light intensities relevant to solar cell operation relatively f
Aiming for better understanding of the large complexity of excited-state processes in carotenoids, we have studied the excitation wavelength dependence of the relaxation dynamics in the carotenoid zeaxanthin. Excitation into the lowest vibrational band of the S-2 state at 485 nm, into the 0-3 vibrational band of the S2 state at 400 nm, and into the B-2(u)+ state at 266 nm resulted in different rel
Electron injection from the transition metal complex Ru(dcbpy)(2)(NCS)(2) (dcbpy = 2,2'-bipyridine-4,4'-dicarboxylate) into a titanium dioxide nanoparticle film occurs along two pathways. The dominating part of the electron injection proceeds from the initially excited singlet state of the sensitizer into the conduction band of the semiconductor on the sub-hundred-femtosecond time scale. The slowe
A 2-month psychological questionnaire concerning pregnancy was answered by 20,920 nondiabetic mothers of singletons. Retrospective analysis showed increased levels of islet autoantibodies (1A) in 290 (1.4%) newborns. High IA levels in the child's cord blood correlated strongly with IA levels in the mother (GADA r = 0.91, P < 0.0001; IA-2A r = 0.75, P = 0.0001). High IA levels were found in newborn
Today document archives are geographically distributed but often not replicated. This can potentially result in a low quality of service in terms of reduced availability and long user-perceived access times. Instead of indiscriminate replication we study the effectiveness of caching techniques such as prefetching and selective preloading. Our technique analyzes whether user access behavior is pred

On the difficulties of developing a European transnational movie star system. Contains comparisons with the star system in soccer.
Compaction and shear strength tests have been performed on different compacted fine-grained tills. The results show that the water sensitivity of the soil is not only dependent on particle size but also on the soil's chemical composition. Comparisons between modified Proctor and the moisture condition value (MCV) show similarities between the optimum moisture content despite the differences in com
A new Regulation on nutrition and health claims came into force in 2007 with implementation during a three-year period and will harmonise this area within the European Community. It makes provision for health claims on foods, including reduction of disease risk claims, and thus recognises the importance of food and nutrition for health. Member states have provided suggestions for claims regarding
Popular Abstract in Swedish Urinvägsinfektioner (UVI) är en av våra vanligaste infektionssjukdomar och orsakas oftast av bakterien Escherichia coli (E. coli). Infektionernas svårighetsgrad varierar, beroende på samspelet mellan bakterie och värd. Njurbäckeninflammation kan orsaka allvarliga störningar av njurfunktionen och kan till och med vara livshotande. Blåskatarr är en mindre allvarlig sjukdoUrinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. The difference in disease severity reflects the virulence of the infecting strain and the propensit
Gaia is ESA’s ambitious space astrometry mission with a foreseen launch date in early 2012. Its main objective is to perform a stellar census of the 1000 Million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS) - the math
Objective: Type 2 diabetes is heterogeneous in its clinical features, pathogenesis, and predisposing or causal genetic factors. This report examines what is known and what needs to be learned about the potential to individualize glycemic therapies in type 2 diabetes, based on phenotypes and genotypes. Participants: A 29-member international working group with expertise in diabetes epidemiology, ph
Over the past decade, the artworld has seen the emergence of various new art genres such as post-internet art, post-media art, and Internet-aware art to name a few. What these genres insinuate is an era of transition between us and digital media, between our online sphere and our offline sphere. This development affects all agents of the artworld, namely, the gallery system, the art-market and mos
Syfte Syftet med denna uppsats är att bidra med kunskap kring hur ehandelsföretag bedriver sitt CRM- respektive CSR-arbete, för att därigenom få insikt i eventuell problematik och risk med att konsumenternas personliga integritet kränks till följd av företagens CRM-strategier.

With this research we aim to understand the dynamics of consumers' use of cancel culture as a resource for their identity construction online. Theories included were surrounding framing, morality, consumers as moral protagonists, purity and dirt as well as distaste and symbolic violence. These theories were selected to aid with the analysis of the empirical material and to add new insight to t
