Due to its unique ability to split water, Photosystem II (PSII) is easily accessible to oxidative damage. Photoinhibited PSII centres diffuse laterally from the grana core region of the thylakoid membrane to the stroma lamellae in order to allow replacement of damaged proteins and cofactors. The 'new born' PSII centres in this region are characterized by the absence of the water splitting capacity

Birds appear to use their tails during flight, but until recently the aerodynamic role that tails fulfil was largely unknown. In recent years delta-wing theory, devised to predict the aerodynamics of high-performance aircraft, has been applied to the tails of birds and has been successful in providing a model for the aerodynamics of a birds tail. This theory now provides the conventional explanati

This thesis presents work within the area of ubiquitous computing, an area based on a vision of computers blending into the background. The work has been done within the EU project PalCom that introduces palpable computing. Palpable computing puts a new perspective on ubiquitous computing, by focusing on human understandability. The thesis goals are to allow for ad-hoc combinations of services an

The problem whether endogenous nitric oxide (NO) may serve as a true physiological regulator of vascular tone in vivo was approached by testing its role during graded acute haemorrhage with the aid of the nitric oxide synthase (NOS) inhibitor L-NAME. The study was performed on the vascular bed of cat skeletal muscle with a technique permitting quantitative recordings of vascular resistance in the

Objective: To determine if the correlation between magnitude of creatine kinase-myocardial band release after coronary artery bypass surgery and 6-month mortality is comparable to that of patients admitted with an acute coronary syndrome. Methods: The GUARDIAN trial tested the efficacy of cariporide, an Na+/H+ exchange inhibitor, on reduction of myocardial ischemia or death in high-risk patients.

Traditional fragmented and mechanistic science is unable to cope with issues about sustainability, as these are often related to complex, self-organizing systems. In the paper, sustainable development is seen as an unending process defined neither by fixed goals nor by specific means of achieving them. It is argued that, in order to understand the sources of and the solutions to modern problems, l

Genetic factors appear to contribute to the severity and progression of diabetic retinopathy. We assessed the associations of the C807T and Glu505Lys variants of the glycoprotein Ia (alpha(2) integrin) subunit of the platelet/endothelial collagen receptor and risk of retinopathy in a population-based survey of 288 diabetic patients in one Swedish community. Neither variant was associated with reti

This thesis analyses educational investments and labour market attachment for refugee immigrants who received a permanent visa to Sweden during 1987-1991. It consists of five self-contained chapters. Chapter 2 presents a brief overview of the historical process behind immigration to Sweden from the post-war period until today, give an orientation on the development of Swedish immigration policy du

The gene encoding calpain-10 (CAPN10) has been identified as a candidate gene for type 2 diabetes. Our aim was to study the impact of genetic (heritability and polymorphisms) and nongenetic (insulin, free fatty acids, and age) factors on CAPN10 mRNA expression in skeletal muscle using two different study designs. Muscle biopsies were obtained before and after hyperinsulinemic-euglycemic clamps fro

Polymorphonuclear leukocyte infiltration into tissues in host defense and inflammatory diseasecauses increased vascular permeability and edema formation through unknown mechanisms.Here, we report the involvement of a paracrine mechanism in neutrophil-evoked alteration inendothelial barrier function. We show that upon neutrophil adhesion to the endothelial lining,leukocytic 2 integrin signaling tri

Hur mycket kostar det i Sverige att “sätta en jude på plats“? Enligt dagens rättspraxis ett tusen kronor i skadestånd, för psykiskt lidande, samt 50 till 80 dagsböter. Detta pris är, enligt Skövde tingsrätt, ett kraftigt straff. Den 28 augusti 1991 åtalades två unga män, E och F, vid Skövde tingsrätt för “ofredande“ av S, en värnpliktskamrat av judisk härkomst. De två unga männen hade “smädat“ S g

Popular Abstract in Swedish Korrosion av stålarmering i betong orsakade höga reparationskostnader för Ölandsbron, och är en grundläggande fråga vid val av material och utförande för Öresundsbron. Avhandlingen behandlar hur val av betongkvalité och tjocklek hos betongen som skyddar armeringen påverkar dels hur fort saltvatten tränger in i betong för att till slut nå armeringen, dels hur mycket Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. Measured total chloride thresholds for uncracked concret

A compartmental model describing the distribution and retention of radioactive iodide in thyroid and other organs is presented. The model is developed from published ICRP models. It is designed primarily for radiation dosimetry of iodine radionuclides used in nuclear medicine, but may also be useful for occupational radiation protection. In the proposed model, the distribution of iodide to the thy
