A model for the third order optical response of carotenoids is used to analyse transient grating and pump-probe data of peridinin in solution and bound in the peridinin-chlorophyll protein (PCP). For peridinin in solution, the transient grating signal detected at 505 nm exhibits a bi-exponential recovery whose fast phase is assigned to relaxation from the S-2 state that has a lifetime of 75 +/- 25
This is at study of a food riot that took place in the southern Swedish city of Malmö in 1799. It demonstrates that E P Thompon’s influential concept of a “moral economy” still is a quite productive analytical tool. Focusing on the relation between the crowd and the authorities, the essay demonstrates that a moral economy was partly shared by the two groups, but clashed with the new ideology of fr
A search for resonant WZ production in the l nu l'l' (l, l' = e, mu) decay channel using 20.3 fb(-1) of root s = 8 TeV pp collision data collected by the ATLAS experiment at LHC is presented. No significant deviation from the Standard Model prediction is observed and upper limits on the production cross sections of WZ resonances from an extended gauge model W' and from a simplified model of heavy
Popular Abstract in Swedish Pankreascancer (cancer i bukspottkörteln) utgör fjärde orsak död i cancer. Det är den cancerform som har den dystraste prognosen av alla, med en 5-års överlevnad mindre än 6%. Sjukdomsrelaterade symptom uppträder ofta sent i förloppet och det saknas metoder för tidig diagnos varför de flesta av patienterna upptäckts i sent skede. Endast cirka 20 procent av patienterna kPancreatic cancer (PC) is the fourth leading cause of cancer-related deaths, with a 5-year survival less than 6%. It does not show any symptoms in its early stages, hence most (>85%) of the patients are diagnosed at late stage. At the time of diagnosis, metastases are frequently observed which make most patients unsuitable for curative surgical treatment and chemotherapy remains the only choice fo
Here, we investigated the structure of natural montmorillonite (MMT) and modified Cloisite C15A (MMT pre-intercalated with a dimethyl-dehydrogenated tallow quaternary ammonium surfactant) nanoclays in the wheat gluten-urea matrix in order to obtain a nanocomposite with improved barrier and mechanical properties. Small-angle X-ray scattering indicated that the characteristic hexagonal closed packed
Objective The aim of this study was to describe the frequency, attribution, outcome and predictors of seizures in systemic lupus erythematosus (SLE). Methods The Systemic Lupus International Collaborating Clinics, or SLICC, performed a prospective inception cohort study. Demographic variables, global SLE disease activity (SLE Disease Activity Index 2000), cumulative organ damage (SLICC/American Co
The development and expansion of evaluation theory and practice is at the core of several different disciplines. There exist different traditional Information System (IS) evaluation approaches, like experimental, pragmatic, constructivist, pluralist and realist IS evaluation. IS evaluation approaches are influenced by the way they address to technology. Recently actor network theory (ANT) and soci
Popular Abstract in Swedish När det blir stopp i ett av hjärtats kranskärl blockeras blodflödet till hjärtat, vilket kan orsaka blodbrist i en del av hjärtmuskeln. Detta kan i sin tur leda till hjärtinfarkt, vilket tar död på hjärtmuskelceller och skadar hjärtat. Vid den efterföljande behandlingen av hjärtinfarkt kan små proppar i kranskärlen, så kallade mikroembolier, ytterligare förvärra skadan Myocardial infarction (MI) following an acute coronary occlusion is a leading cause of morbidity and mortality. During revascularization, microemboli may complicate treatment and affect cardiac function. The long-term effects of microembolization are not fully elucidated. Following an MI it is important to accurately determine the size of the infarction, as it can be used for guidance in terms of
Utifrån aktuell forskning kring publik och reception, och mot bakgrund av en förskjutning inom samtidens scenkonst mot åskådarnas delaktighet och medansvar söker texten uppvärdera publiken och de många aspekter av teaterhändelsen som receptionsperspektivet aktualiserar, och bidra till en omdefiniering av teaterns problem och dess uppdrag visavi publiken.
AimOral mucositis is a common and debilitating side effect of haematopoietic stem cell transplantation. Our study investigated parents' and children's experiences of oral mucositis treatment and whether the parents' perceptions accurately reflected the children's views. MethodsWe analysed 71 questionnaires completed by the parents of children who had undergone haematopoietic stem cell transplantat
Based on a known observation that symplecticity is preserved under certain Sundman time transformations, adaptive symplectic integrators of an arbitrary order are constructed for separable Hamiltonian systems, for two classes of scaling functions. Due to symplecticity, these adaptive integrators have excellent long-time energy behaviour, which is theoretically explained using standard results on t
Quinoa stalk (Chenopodium quinoa Willd.) from agricultural crop residue, totora (Schoenoplectus tatora) and o-macrophytes (aquatic flora) from Lake Titicaca (on the Bolivian Altiplano) were studied in a wet anaerobic co-digestion process together with manure front llama, cow and sheep. Anaerobic semi-continuous experiments were performed in (10) 2-1 reactors at a temperature of 25 degrees C with 3
Very old persons (80+) are often described as "frail", implying that they are particularly vulnerable to adverse health outcomes. Elderly Persons in the Risk Zone was designed to determine whether a preventive home visit or multiprofessional senior group meetings could postpone deterioration in frailty if the intervention is carried out when the person is not so frail.
Heterostructure nanowires have many potential applications due to the avoidance of interface defects by lateral strain relaxation. However, most heterostructure semiconductor nanowires suffer from persistent interface compositional grading, normally attributed to the dissolution of growth species in the common alloy seed particles. Although progress has been made for some material systems, most bi
The thermal stresses in a concrete bridge are affected by the surrounding climate. Varying temperature will produce movements which, if restrained, may induce stresses in the structure. To predict the thermal stresses in box cross-sections, FE simulations have been performed with extensive climatic input data to simulate the temperature and resulting stress fields in the hollow concrete arch of th
