Efficiency in Education - A Multilevel Analysis

Popular Abstract in Swedish Kostnaden för grund- och gymnasieskolan i Sverige motsvarar idag ca 4,5% av BNP. Med tanke på investeringens storlek är det viktigt att dessa resurser används effektivt. I avhandlingen studeras effektivitet inom den kommunala skolan på tre nivåer: Kommunal nivå, skolnivå och individuell nivå. Effektiviteten skattas i linjärprogrammeringsmodeller, genom så kallad Data EnSweden spends altogether about 4.5% of GDP on primary, secondary and upper secondary school. Considering the magnitude of this investment it is important that these resources are used efficiently. In this thesis efficiency in public education is analysed on three different levels: The municipal level, the school level, and the individual level. Efficiency is estimated using a linear programming te

Behandling av osteoporotisk kotkompression. Explosionsartat intresse för vertebroplastik och kyfoplastik

Vertebroplastik och kyfoplastik är två nya behandlingsmetoder vid osteoporotiska kotkompressioner, där man genom en perkutant insatt kanyl fyller den skadade kotkroppen med bencement så att frakturen stabiliseras, ryggsmärtan reduceras och patientmobiliseringen underlättas. Det finns inga prospektiva, randomiserade, kontrollerade studier publicerade som värderar effekterna av vertebro- och kyfoplaDuring the last 15 years, two new treatment strategies have gained worldwide attention in the treatment of osteoporotic vertebral fractures. The exponential increase in the use of percutaneous vertebro- or kyphoplasty has up to now not been supported by scientific sound evidence-based data. There exist no prospective randomised controlled trials (RCT) that support the efficacy of the treatments, n

Energy use in multi-family dwellings : measurements and methods of analysis

In 2001, multi-family dwellings were built at nine properties in Västra hamnen, Malmö, Sweden. Several well known Swedish architects were involved in designing the buildings, hence they reflect modern architecture. Prior to the inauguration, the buildings were displayed at the international housing exhibition Bo01. The housing exhibition had an ecological and sustainability focus. Regarding energy

Topics in Complex Analysis and Operator Theory I. The shift operator on spaces of vector-valued analytic functions II. Fatou-type theorems for general approximate identities III. Preduals of Q_p-spaces

Popular Abstract in Swedish Del I - "The Shift Operator on Spaces of Vector-valued Analytic Functions" består av tre artiklar som alla handlar om en viss sorts operatorer i Cowen-Douglas klassen med spektrum på enhetsskivan D, eller om man så vill, om operatorn Mz (multiplikation med z) på Hilbert rum H av vektorvärda analytiska funktioner på D. Den första artikeln, "On the Cowen-Douglas class forThis thesis consists of six articles on three different subjects in the area of complex analysis, operator theory and harmonic analysis. Part I - "The Shift Operator on Spaces of Vector-valued Analytic Functions" consists of three closely connected articles that investigate certain operators in the Cowen-Douglas class with spectrum D - the unit disc, or equivalently, the shift operator M_z

Apolipoprotein M: Progress in understanding its regulation and metabolic functions

ApoM is a novel apolipoprotein mainly present in high-density lipoprotein (HDL). It belongs to the lipocalin protein superfamily and may bind a small but so far unknown lipophilic ligand. It is secreted without cleavage of its hydrophobic signal peptide, which probably anchors apoM in the phospholipid moiety of plasma lipoproteins. Recent studies suggest that apoM may affect HDL metabolism and hav

Leva med stroke - lära av erfarenheter

Popular Abstract in Swedish Denna avhandling handlar om hur personer, som insjuknat i stroke, beskriver sina upplevelser och erfarenheter av att leva med stroke och hur de lär sig hantera sin livssituation. Kunskaper om läroprocesser i en livsomställning, som insjuknande i stroke innebär, är betydelsefulla för att kunna förstå, möta och stödja människor i sådana situationer. Under de senaste årtioThis thesis concerns how people with stroke describe their experiences of life with stroke and how they learn to live with stroke. In the western world the interest for research in lived experiences has increased. This might be due to the higher rate of people with illness and lifelong diseases. The aim of the study is to analyze stories from persons with stroke of their lived experiences of life

A comparison of structural and mechanical properties in cancellous bone from the femoral head and acetabulum

Mechanical interlock obtained by penetration of bone cement into cancellous bone is critical to the success of cemented total hip replacement (THR). Although acetabular component loosening is an important mode of THR failure, the properties of acetabular cancellous bone relevant to cement penetration are not well characterized. Bone biopsies (9 mm diameter, 10 mm long) were taken from the articula

Antibodies to intimin and Escherichia coli secreted proteins A and B in patients with enterohemorrhagic Escherichia coli infections

Enterohemorrhagic Escherichia coli produce an attaching and effacing lesion upon adhering to the intestinal epithelium. Bacterial factors involved in this histopathology include the intimin adhesin and E. coli secreted proteins (Esps) A and B. In this study we investigated the serum antibody responses to recombinant E. coli O157:H7 intimin, EspA, and EspB by immuno-blotting. Canadian patients with

In utero and lactational exposure to TCDD; steroidogenic outcomes differ in male and female rat pups

TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) has a potency to induce decreased fertility and structural reproductive anomalies in male and female mammals. While the activity profile of sex steroid hormone production distinctly differs in developing males and females, we wanted to analyze sex-specific effects of TCDD introduced in utero and via lactation on gonadal steroidogenesis and gonadotropin le

Simultaneous reduction of SO2 and NOx in an entrained-flow reactor

Simultaneous SO2 and NOx reduction in flue gas by the dry furnace sorbent injection process was simulated with an entrained-flow reactor. Several ammonium salts as well as urea were tested. Urea was found to give the highest NOx removal efficiency. By using urea-limestone sorbent, >90% SO2 removal and >80% NOx removal were obtained at Ca/S and N/NOx ratios both equal to 2. The DeNO(x) process is m

Värmeförluster till mark : grundläggning av typen platta på mark

Effekten av olika kantisoleringar, ändringar av ute- och innetemperaturer, köldknäppar, tjäle och snö beräknas samt värmeförluster vid ny byggnad under uppbyggnad av värmekudde.

On Development and Characterisation of Continuous Ink Jet Nozzles

This thesis concerns nozzles and their impact on droplet formation and droplet flight in a continuous ink jet printer. Methods are suggested to characterise droplet formation and droplet flight stability (D.F.S.). A study about the influence of droplet flight stability on the quality of print out is presented. A method to assess the charging process for the continuous ink jet is described. The dev

Analysis of the hypoxia-induced ADH2-promoter of the respiratory yeast Pichia stipitis reveals a new mechanism for sensing of oxygen limitation in yeast

We introduced a reporter gene system into Pichia stipitis using the gene for the artificial green fluorescent protein (GFP), variant yEGFP. This system was used to analyse hypoxia-dependent PsADH2 regulation. Reporter gene activity was only found under oxygen limitation on a fermentable carbon source. The promoter was not induced by oxygen limitation in the Crabtree-positive yeast Saccharomyces ce
