Popular Abstract in Swedish Under det senaste decenniet har risker med och alternativ till allogent blod (blod från främmande givare) debatterats mycket pga. risken för smitta, allergiska reaktioner, samt starka indicier som talar för att blod från främmande givare kan påverka immunförsvaret hos mottagaren. Därför vill man gärna begränsa mängden tillfört givarblod under kirurgiska ingrepp på barn,In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23

Uppsatsen försöker att ta ett samlat rättssociologiskt grepp om kränkningsersättningen som är den viktigaste formen av brottsskadeersättning (under år 2006 betalade Brottsoffermyndighe-ten ut över 81 miljoner konor i kränkningsersättning). Hur dessa skador värderas och konstrueras speglar samhällets rättskultur och ger upphov till en rad rättssociologiska frågeställningar om rättens roll och samsp

The solution properties of two water-soluble polymers, poly(acrylic acid) (PAA), covalently labeled with the fluorescent hydrophobic dye naphthalene (Np), have been investigated in water:organic solvent mixtures. The naphthalene chromophores have been randomly attached, onto the polymer, with two different degrees of labeling. Fluorescence measurements (steady-state and time-resolved) have been us

The aim of this study was to determine the threshold of fracture probability at which interventions became cost-effective in men and women, based on data from Sweden. We modeled the effects of a treatment costing $500 per year given for 5 years that decreased the risk of all osteoporotic fractures by 35% followed by a waning of effect for a further 5 years. Sensitivity analyses included a range of

The cone snail is the only invertebrate system in which the vitamin K-dependent carboxylase (or gamma-carboxylase) and its product gamma-carboxyglutamic acid (Gla) have been identified. It remains the sole source of structural information of invertebrate gamma-carboxylase substrates. Four novel Gla-containing peptides were purified from the venom of Conus textile and characterized using biochemica

Epigenetic variation may contribute to the development of complex metabolic diseases such as type 2 diabetes (T2D). Hepatic insulin resistance is a hallmark of T2D. However, it remains unknown if epigenetic alterations take place in the liver from diabetic subjects. Therefore, we investigated the genome-wide DNA methylation pattern in the liver from subjects with T2D and non-diabetic controls and

In the present work non-idealities of flat burner-stabilized flames at atmospheric and low pressures are examined using PIV measurements, which are supported by and analyzed with the help of CFD modeling. Radial and axial velocity profiles measured in the cold flow and in the flames at atmospheric and at lower pressures are presented. Two possible reasons for the drop in the apparent laminar burni

It is recommended that intervention thresholds should be based on absolute fracture risk, but there is a large variation in hip fracture incidence from different regions of the world. The aim of this study was to examine heterogeneity of hip fracture probability in different regions from recent estimates of hip fracture incidence and mortality to adjust intervention thresholds. Ten-year probabilit

Popular Abstract in Swedish Hos människan lever en rad mikroorganismer som tillsammans utgör normalfloran. Normalfloran återfinns på alla kroppsytor, det vill säga huden och slemhinnorna i munnen, svalget, magsäcken, tunn- och tjocktarmen, vagina och urinrörsmynningen. Samspelet mellan människokroppen och mikroorganismerna utsätts dagligen för påfrestningar. En sådan naturlig påfrestning är de sjuThis thesis is concerned with a family of bacterial surface proteins expressed by different strains of the anaerobic Gram-positive, commensal and human pathogen Peptostreptococcus magnus. These proteins have been studied with respect to their role in virulence, function, structure, and evolution. Strains isolated from patients with vaginosis have previously been shown to be associated with express

This chapter introduces basic differences between Free/Open Source Enterprise Resources Planning systems (FOS-ERP) and Proprietary ERP (P-ERP), revisiting the previous work of Carvalho (2008). Taking into account that some years has passed and the economic downturn came, it updates key aspects of FOS-ERP under both vendor and adopter perspectives. Like its predecessor, this chapter contributes to

The apparent permeability index is widely used as part of a general screening process to study drug absorption, and is routinely obtained from in vitro or ex vivo experiments. A classical example, widely used in the pharmaceutical industry, is the in vitro Caco-2 cell culture model. The index is defined as the initial flux of compound through the membrane (normalized by membrane surface area and d

The decay of core-excited electronic states in free 1,3 trans butadiene molecules has been studied using high-resolution synchrotron radiation and electron spectrometry. The core-level energy shift between the terminal and central carbon atoms is 0.64 eV making selective excitation of core electrons from these atoms possible. Resonant excitation to the au(*) valence state leads to autoionizing dec

Background Postoperative policies of "wait-and-see" and radiotherapy for low-grade glioma are poorly defined. A trial in the mid 1980s established the radiation dose. In 1986 the EORTC Radiotherapy and Brain Tumor Groups initiated a prospective trial to compare early radiotherapy with delayed radiotherapy. An interim analysis has been reported. We now present the long-term results. Methods After s

By measuring excited state and charge dynamics in blends of an alternating polyfluorene copolymer and fullerene derivative over nine orders in time and two orders in light intensity, we have monitored the light-induced processes from ultrafast charge photogeneration to much slower decay of charges by recombination. We find that at low light intensities relevant to solar cell operation relatively f

The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. Aspects of costs and energy demand while using NF at elevated temperatures were also evaluated. The increa

The purpose of this thesis has been to analyse the mechanism of the market driving approach carried out by a global organisation with a corporate brand. Market driving is a new organisational approach to strategy that lacks a solid theoretical framework, but constitutes a reality of global firms such as IKEA, The Body Shop, Benetton, Dell, Hennes and Mauritz, Starbucks. In the literature, the mark
