Feedbacks, or internal interactions, play a crucial role in the climate system. Negative feedback will reduce the impact of an external perturbation, a positive feedback will amplify the effect and could lead to an unstable system. Many of the feedbacks found in the climate system are positive; thus, for example, increasing CO2 levels will increase temperature, reduce the snow cover, increase the

Popular Abstract in Swedish Ordet "fängelse" ger mångfaldiga och motstridiga associationer; till höga murar och gallerförsedda fönster, till inspärrning, straff och farliga brottslingar men också till förtryck, utstötthet och trasiga människor. De svenska fängelserna växte fram under 1800-talet och var en del i en internationell trend. Fängelset framställdes som ett stort humanitärt och straffrättThe general aim of the thesis is to study 19th century Swedish prisons from the point of view of the surrounding discourse and also as a social system. The prison phenomenon grew out of the meeting between prisons as a discourse-produced norm system and the social practice consisting of the reality as experienced by the prisoners and the prison staff. The growth and development of the Swedish pris

The presence of a functional glpT gene in Haemophilus influenzae could be questioned, since there is only what appears to be a truncated glpT (HI0686, 143 nt in the 5'-end) available in the H. influenzae Rd genome database (Fleischmann et al. , 1995). For cloning of the glpT gene from H. influenzae type b strain Eagan, an isogenic glpT, rec-1 double mutant and a selective medium for detection of t

OBJECTIVE: To find out the prevalence of symptomatic non-palpable groin hernias in women under 40 years old with undiagnosed chronic groin pain. DESIGN: Retrospective analysis. SETTING: University hospital, Sweden. SUBJECTS: 116 women 14-39 years old (mean 27) with chronic undiagnosed groin pain who underwent herniography 1977-1994. INTERVENTIONS: Intraperitoneal injection of 80 ml iodine contrast

The relationships between characteristics of the ward atmosphere and treatment outcome in a psychiatric day-care unit were investigated. The treatment programme was based on occupational group therapy and included long-term mentally ill patients, equally distributed with regard to psychosis and non-psychosis diagnoses. The ward atmosphere was rated on the Community-Oriented Programs Environment Sc

Activity quantification in nuclear medicine imaging is highly desirable, particularly for dosimetry and biodistribution studies of radiopharmaceuticals. Quantitative In-111 imaging is increasingly important with the current interest in therapy using Y-90 radiolabeled antibodies. One of the major problems in quantification is scatter in the images, which leads to degradation of image quality. The a

BACKGROUND: Although age is associated with increasing blood pressure, there is a substantial heterogeneity within a certain birth cohort. Whether increase in systolic and diastolic blood pressure is related to pulmonary function is largely unknown. OBJECTIVE: To study blood pressure elevation between 55 and 68 years of age in relation to vital capacity (VC) and forced expiratory volume (FEV1.0) a

Popular Abstract in Swedish Cellerna i blodet har en rad skilda funktioner, såsom att transportera syre, levra blodet vid behov eller att på olika sätt delta i vårt immunförsvar. Alla blodets celler härstammar från en s k stamcell som har förmåga att genom en rad förändringar mogna ut till vilken typ av cell som helst i blodsystemet. Leukemi är en sjukdom som drabbar blodet och som uppstår p g a aAcute myeloid leukemia (AML) is commonly associated with balanced chromosomal translocations. Characteristically, these translocations lead to the fusion of two unrelated genes, resulting in the expression of an aberrant fusion protein. t(8;21) is one of the most common translocations found in patients with AML. It results in the expression of the chimeric protein AML1-ETO. AML1 is a transcription

Despite improvements in therapy for children with type 1 diabetes, the prevalence of cardiovascular morbidity in adulthood due to accelerated atherosclerosis remains significant (1). Similar to other cardiovascular risk factors, the diabetic state facilitates arterial endothelial injury, a primary event in the pathogenesis of atherosclerosis (2). Although several pediatric studies have reported an

1. Five oligotrophic clear-water lakes on the Faroe Islands were studied during August 2000. Algal and bacterial production rates, community respiration, and CO2 saturation were determined. In addition, we examined the plankton community composition (phytoplankton and heterotrophic nanoflagellates) and measured the grazing pressure exerted by common mixotrophic species on bacteria. 2. High respir

BACKGROUND: In peritoneal dialysis, approximately 40% of the total osmotic ultrafiltration (UF) induced by glucose can be predicted to be due to "free" water transport across aquaporin-1 (APQ-1). Theoretically, it would be possible to assess the fraction of free water transport in the early phase of a hypertonic dwell, when UF rate is high and the relative contribution of Na+ diffusion is low. La

Man kan inte få reda på hur Jesus såg ut och exakt formulerade sig – t.o.m. ”Fader Vår” har vi i två rätt olika versioner. Hans egna verbala mönster skiner dock igenom evangelietraditionen, och går, liksom ett stort antal innehållsliga temata centrerade kring gudsriket, sannolikt tillbaka till Jesus själv. Två inflytelserika forskningsidéer, den om den obegränsade formbarheten i muntlig tradering

Popular Abstract in Swedish Diskussionen tar sin utgångspunkt i den klyfta som finns mellan, å ena sidan, stora delar av forsknings- och policy-världen och, å andra sidan, den verklighet som författaren stött på ute på den afrikanska landsbygden. Forskningsvärlden ser vattenresurser som en rent ekonomisk tillgång och småskaliga bönder beskrivs såsom vinstmaximerande individer, medan verkligheten äAllocation, control, and management of natural resources are issues that absorb researchers within both the social and natural sciences. This study deals with such research questions as well as with one of the most fundamental issues in Economic History – namely institutional change. The plot is set around continuity and change of property rights institutions governing water resources. The setting

The uptake of N-15-labelled alanine, ammonium and nitrate was studied in ectomycorrhizal morphotypes of intact Pinus sylvestris seedlings. PCR-RFLP analysis of the ITS-region of fungal rDNA was used to identify the morphotypes. Seedlings were grown in forest soil collected at an experimental site in southern Sweden. The treatments compared were a control, N fertilisation (600 kg N ha(-1) as urea),
