Vibronic origin of long-lived coherence in an artificial molecular light harvester.

Natural and artificial light-harvesting processes have recently gained new interest. Signatures of long-lasting coherence in spectroscopic signals of biological systems have been repeatedly observed, albeit their origin is a matter of ongoing debate, as it is unclear how the loss of coherence due to interaction with the noisy environments in such systems is averted. Here we report experimental and

Tubular and glomerular kidney effects in Swedish women with low environmental cadmium exposure

Cadmium is a well-known nephrotoxic agent in food and tobacco, but the exposure level that is critical for kidney effects in the general population is not defined. Within a population-based women's health survey in southern Sweden (Women's Health in the Lund Area, WHILA), we investigated cadmium exposure in relation to tubular and glomerular function, from 1999 through early 2000 in 820 women (71%

Sydsvenska baptister inför myndigheter. Tillämpning av religionsbestämmelser i Lunds och Växjö stift 1857-1862.

Popular Abstract in Swedish Under 1850-talet framträdde baptismen som den första verkliga frikyrkorörelsen i Sverige. Den tog helt och hållet avstånd från det ordinära kyrkolivet och kom därför i konflikt med samhällets religiösa regelverk. Kyrkliga och världsliga myndigheter betrktade baptismen som villfarande och samhällsupplösande. Deras agerande mot baptisterna i landets södra delar blir i denDuring the 1850's, Baptism appeared as the first real free church movement in Sweden. It distanced itself completely from normal church life and therefore came into conflict with society's religious rules. Ecclesiastical and temporal authorities regarded Baptism as erroneous and social disruptive. In the present treatise, their actions against the Baptists in the southern parts of the country beco

Laser pulse control of exciton dynamics in the FMO complex: Polarization shaping versus effects of structural and energetic disorder

Femtosecond laser pulse control of exciton dynamics in biological chromophore complexes is studied theoretically using the optimal control theory specified to open quantum systems. Based on the laser pulse induced formation of an excitonic wave packet the possibility to localize excitation energy at a certain chromophore within a photosynthetic antenna system (FMO complex of green bacteria) is inv

Functional role of aerobic glycolysis in rat portal vein

The functional role of aerobic lactate production in the rat portal vein was investigated. Changing substrate from glucose (11.5 mM) to pyruvate (11.5 mM) or beta-hydroxybutyrate (3 mM) had virtually no effect on spontaneous mechanical activity. Lactate production (FLA) was smaller with pyruvate than with glucose (0.05 +/- 0.01 vs. 0.14 +/- 0.03 mumol g-1 min-1, n = 4). Addition of 0.5 mM iodoacet

Autocatalytic behaviour in esterification between anhydrides and alcohols

In this work the Arrhenius parameters and heat of reaction for the esterification of acetic anhydride by methanol and the esterification of propionic anhydride by 2-butanol were determined using a CPA 202 reaction calorimeter (ChemiSens). Three reaction rate models were tested for each of the esterification reactions, two of which assumed autocatalytic behaviour. The autocatalytic models were base

The distance scale of planetary nebulae

By collecting distances from the literature, a set of 73 planetarynebulae with mean distances of high accuracy is derived. This sample isused for recalibration of the mass-radius relationship, used by manystatistical distance methods. An attempt to correct for a statisticalpeculiarity, where errors in the distances influences the mass-radiusrelationship by increasing its slope, has been made for t

The resolution of the Nirenberg-Treves conjecture

We give a proof of the Nirenberg-Treves conjecture: that local solvability of principal-type pseudo-differential operators is equivalent to condition (Psi). This condition rules out sign changes from - to + of the imaginary part of the principal symbol along the oriented bicharacteristics of the real part. We obtain local solvability by proving a localizable a priori estimate for the adjoint opera

Topographical organization of the cerebellar cortical projection to nucleus interpositus anterior in the cat

1. A new methodological approach for detailed study of the organization of the cerebellar corticonuclear projection was evaluated in barbiturate-anaesthetized cats. Extracellular field potentials were simultaneously recorded in nucleus interpositus anterior and in the forelimb area of the C3 zone, at the cerebellar surface. On electrical and natural stimulation of the forelimb skin, the evoked pos

Metabolic impact of a family history of Type 2 diabetes. Results from a European multicentre study (EGIR)

BACKGROUND: Insulin resistance was found in some but not in all previous studies of non-diabetic first degree relatives of Type 2 diabetic patients. Small study groups, ethnic differences and/or non-optimal techniques may explain the conflicting results. AIM: To study the impact of a family history of Type 2 diabetes on insulin action in a large group of non-diabetic Europeans using the 'gold stan

Picosecond-lidar thermometry in a measurement volume surrounded by highly scattering media

In this work, a picosecond-lidar system, using a Nd:YAG picosecond laser, a Newtonian telescope and a streak camera, was used for single-ended furnace diagnostics. The optical access of the furnace was obstructed by a sooty diffusion ethylene flame. It was demonstrated that, with proper optical arrangement, the elastic scattering of the flame can be mapped in one dimension simultaneously as temper

Fast, rugged and sensitive ultra high pressure liquid chromatography tandem mass spectrometry method for analysis of cyanotoxins in raw water and drinking water-First findings of anatoxins, cylindrospermopsins and microcystin variants in Swedish source waters and infiltration ponds.

Freshwater blooms of cyanobacteria (blue-green algae) in source waters are generally composed of several different strains with the capability to produce a variety of toxins. The major exposure routes for humans are direct contact with recreational waters and ingestion of drinking water not efficiently treated. The ultra high pressure liquid chromatography tandem mass spectrometry based analytical

Additive-induced morphological tuning of self-assembled silica-barium carbonate crystal aggregates

Crystallisation of barium carbonate from alkaline silica solutions results in the formation of extraordinary micron-scale architectures exhibiting non-crystallographic curved shapes, such as helical filaments and worm-like braids. These so-called "silica biomorphs" consist of a textured assembly of uniform elongated witherite nanocrystallites, which is occasionally sheathed by a skin of amorphous

Temaintro: Aristoteles Retoriken

Aristoteles Retoriken utkom 2012 i svensk översättning av Johanna Akujärvi. Därmed finns den nu – äntligen, frestas man att säga – tillgänglig på alla de tre skandinaviska språken: Thure Hastrups danska översättning utkom 1983 och Tormod Eides norska år 2006. Det betyder att skandinaviska läsare nu kan möta en av retorikämnets viktigaste utgångspunkter på sitt modersmål. Att Rhetorica Scandinavic

Fransk litteratur i Sverige 1830-1900. Översättning, reception och spridning

The article presents some results from an international project on the introduction of French literature in Scandinavia during the 19th century. A point of departure is the database BREFS (Bibliographie du Réalisme Français en Scandinavie), containing the translations of novels, short stories, poetic works and theatre plays that were published in Denmark, Finland, Iceland, Norway and Sweden in boo

Pregnancy in heart- and heart/lung recipients can be problematic

Objective. The first successful pregnancy after heart transplantation was reported in 1988. Worldwide experience with heart and heart/lung transplanted (H-HLTx) pregnant women is limited. To expand this knowledge the collaborating Nordic thoracic transplant centers wanted to collect information on all such pregnancies from their centers. Design. Information was retrospectively collected on all H-H
