Ultrafast formation of a carotenoid radical in LH2 antenna complexes of purple bacteria

The SI-mediated carotenoid to BChl a energy-transfer pathway and carotenoid radical formation have been studied using femtosecond time-resolved transient absorption spectroscopy. A series of LH2 complexes (LH2 = light-harvesting complex 2) from Rhodobacter sphaeroides incorporating carotenoids neurosporene, spheroidene, and spheroidenone were used to explore the effect of conjugation length. The S

Chicagoskolan : Institutionaliseringen, idétraditionen och vetenskapen

Popular Abstract in Swedish Forskarna inom Chicagoskolan var de första i ett akademiskt ramverk som systematiskt och etnografiskt satte gruppen och människan i centrum i en modern urban kontext. Det hade förekommit andra som skrivit om industrialism, modernism, urbanitet och de fattiga i slummen, men inte på ett lika systematiskt och genomträngande sätt som Chicagoskolan. Skolans strävan att föranThe main purpose of my thesis is to investigate how the Chicago School in urban sociology, that was active between 1915 and 1935, developed and why it produced so many classical monographs during a period of about ten to fifteen years. To outline the historical reasons for the School to develop I have chosen to view the historical context as a field with different actors. Another related and overa

Economic Analyses of Drinking Water and Sanitation in Developing Countries

Popular Abstract in Swedish Denna avhandling fokuserar på två av de många faktorer som är av fundamental betydelse både för människors välfärd och för ett lands utveckling dvs. val av dricksvattenkälla och toalettfacilitet. I avhandlingen analyseras olika aspekter av hushållsefterfrågan på dessa två faktorer med hjälp av data från Filippinerna och Bangladesh. Avhandlingen består av fem kapitel, etThis thesis focuses on different aspects of household demand, and the determinants of demand, for water and sanitation related inputs fundamental to the households' well-being, i.e. drinking water and toilet facilities. The thesis consists of five chapters, one introductory chapter and four self-contained, essentially empirical, studies. In chapter two, Women's Health Choices and the Effects on C

A quantitative analysis of the N 1s ->pi* photoabsorption profile in N-2: new spectroscopical constants for the core-excited state

The N 1s --> pi* photoabsorption profile of N-2 is quantitatively analysed. New spectroscopical constants for the N 1s(-1) pi* core-excited state are determined from NEXAFS spectra and compared to previously published data. The accuracy of the new spectroscopical constants is discussed and error bars are given for the present data analysis. The goodness of the new spectroscopical constants is demo

Mannen med filmkameran : Studier i modern film och filmisk modernism

The anthology Mannen med filmkameran ("The Man with the Movie Camera") is a Festschrift for Joel Ohlsson, teacher in film studies at former Department for comparative Literature, Lund university. The texts are close readings and formal analyses of contemporary international film.

Functional outcome in rats transferred to an enriched environment 15 days after focal brain ischemia

BACKGROUND AND PURPOSE: The aim was to determine whether a delayed transfer to an enriched environment improves outcome after focal brain ischemia. METHODS: Performance on a rotating pole, prehensile traction, limb placement, and postural reflexes were tested in 15 spontaneously hypertensive rats housed in standard laboratory cages for 2 weeks after middle cerebral artery ligation. Seven of the 15

Occurrence of nematodes, tardigrades and rotifers on ice-free areas in East Antarctica

Nematodes, rotifers and tardigrades were collected on three nunataks (mountain peaks penetrating the ice sheet) in Vestfjella, on six nunataks; in Heimefrontfjella and on the Schirmacher Oasis in East Antarctica in the austral summers of 1996/97 and 2001/02. Most samples were taken on the nunatak Basen in Vestfjella where the Swedish station Wasa is located. The microfauna was patchily distributed

Svensk evangelisk väckelse på Bornholm

I denna uppsats behandlas andliga förbindelser mellan Sverige och Bornholm under 1800- och 1900-talet. Den rosenianska väckelsen kom att i hög grad ge det andliga livet på Bornholm dess särprägel. Liksom den rosenianska rörelsen i Sverige kanaliserades dels i Evangeliska Fosterlandsstiftelsen (EFS), dels i Bibeltrogna Vänner (BV), har motsvarande rörelse på Bornholm förgrenats i Luthersk Missionsf

Characteristic state plasticity for granular materials Part II: Model calibration and results

A non-associated plasticity theory for granular materials has been developed in Part 1 based on the concept of a characteristic stress state of vanishing incremental dilation. The model is fully three-dimensional and is defined by six material parameters: two for elastic stiffness, one for plastic stiffness, two for the shapes of yield and plastic potential surfaces and one for the dilation at fai

Space-Time Prediction of Ocean Winds

The topic of this thesis is inspired by an experiment in which a vessel, laying a submarine cable, was provided with forecasts overlaid with satellite observations of significant wave height. During the operation, the vessel was close to an adverse weather area and the personnel on board could confirm that the forecast was not as close to the "ground truth" as the satellite observation was.

Boron neutron capture therapy for glioblastoma multiforme : Clinical studies in Sweden

A boron neutron capture therapy (BNCT) facility has been constructed at Studsvik, Sweden. It includes two filter/moderator configurations. One of the resulting neutron beams has been optimized for clinical irradiations with a filter/moderator system that allows easy variation of the neutron spectrum from the thermal to the epithermal energy range. The other beam has been designed to produce a larg
