The spectroscopic properties of spirilloxanthin in an nhexane solution and bound to the core light-harvesting LH1) complex of Rhodospirillum rubrum were studied by near infrared ultrafast transient absorption spectroscopy. Global analysis of the kinetic traces measured after excitation of spirilloxanthin to the S2 (1Bu +) state enabled us to estimate the species-associated difference spectra that

All service control nodes can be modelled as a server system with one or more servers processing incoming requests. In this paper we show how non-linear control theory may be used when analyzing admission control mechanisms for server systems. Two models are developed, one linear and one non-linear. We show that, due to the non-linearities appearing in a real server system, linear control theory i

Popular Abstract in Swedish Analysen av källornas uppgifter om uppbyggnadsfasen av de väpnade styrkorna under Muhammad och hans efterföljare kaliferna fram till 680 ger vid handen, att vi här har att göra med en organisation som stod på en likvärdig nivå med sina fiender i ledningsmässigt, strategiskt och taktiskt hänseende. Angreppet på de östromerska provinserna Palestina I-III och Arabia visar In the present work I have studied how the armed forces under Muhammad and the first caliphs were built up and how they operated in the period 622-80. The perspective is that of the history of religion and strategic theory, and comparisons are made with both contemporary and more recent material. The concept of "Strategic surprise attack" formed an important part of the campains that the generals

The thesis Housing Culture, Information Flows, and Craftsmen 1740-1820 (Bostadskultur, informationsflöden och hantverkare 1740-1820) investigates two mansion houses – Bålby in Närke and Skottsbergska gården in Karlshamn – with the focus on craftsmen and their clients. This is in order to analyse the relationship between professional craftsmen in the capital and in other regions. The clients have a

This paper reports proper orthogonal decomposition (POD) analyses for the velocity fields measured in a test burner. The Cambridge/Sandia Stratified Swirl Burner has been used in various studies as a benchmark for high resolution scalar and velocity measurements, for comparison with numerical model prediction. Flow field data was collected for a series of bluff-body stabilized premixed and stratif

Despite its facilitating role in creating opportunities for people with disabilities to exercise human rights, access to assistive technology is limited in many countries. It is therefore promising that the Convention on Rights of Persons with Disabilities (CRPD) addresses this area. The purpose of this study was to analyse the assistive technology content of the CRPD from a basic human rights per

COPD is a progressive disease, which can take different routes, leading to great heterogeneity. The aim of the post-hoc analysis reported here was to perform continuous analyses of advanced lung function measurements, using linear and nonlinear regressions.

The interaction of light with multiple red blood cells was systematically investigated by the finite-difference time-domain method (FDTD). The simulations showed that the lateral multiple scattering between red blood cells is very weak and that the polarization has an almost insignificant influence on the distribution of the scattered light. The numerical results of the FDTD method were compared w

Previously we reported the presence of anti-idiotypic antibodies (anti-Id) specific to autoantibodies against GAD65 (GAD65Ab) in healthy individuals while the activity of anti-Id directed to GAD65Ab in T1D patients was significantly lower. These anti-Id recognize the antigen binding site of GAD65Ab, thus preventing their binding to GAD65. Here we characterized the IgG subclass profile of these ant

The Swedish Mongol Mission (SMM) was an ecumenical union active mostly among Mongols in Outer and Inner Mongolia between 1897 and 1945. SMM were to establish five stations at the borders of the Gobi Desert from 1908 to 1944. The stations were Hallong Osso, Goltjaggan, Dojen, Hatt in Sum, situated in Inner Mongolia and Urga (in present Ulan Bator) situated in Outer Mongolia. In 1950 the activities

We investigated the quality of life (QoL) of newly diagnosed persons with cancer aged 65 years at baseline and 3 months after, in relation to age, contact with the healthcare system, activities of daily living, hope, social network and support using the European Organization for Research and Treatment of Cancer QLQ-C30, Katz ADL, Nowotny's Hope Scale, and the Interview Schedule for Social Interact

Rotational Coherent anti-Stokes Raman spectroscopy (CARS) has the last decades been developed into a useful tool for thermometry and concentration measurements in combustion. In this paper, we present a novel polarization approach of the technique, which will enhance its potential and widen the range of conditions at which it can be utilized. The theory of the polarization approach is described in

CagA seropositivity is an important risk factor for gastric adenocarcinoma and duodenal ulcer. However, CagA seropositivity is also found in Helicobacter pylori-seronegative subjects. Is CagA seropositivity in these subjects a sign of a past H. pylori infection, or does it represent a false-positive reaction? This study investigates the intensity of the CagA immune reaction and the variation in Ca

Helicobacter pylori is a cause of chronic gastritis and leads to development of atrophy in some cases. There is evidence that the heat shock protein 60 (HSP60) of H. pylori is involved in induction of chronic inflammation. Seroprevalence of IgG antibodies to H. pylori HSP60 in an adult cohort from Saaremaa, Estonia (68 persons, median age 57 years), with a high prevalence of antibodies to cell sur
