Organic carbon and bacteria have a high variability at different scales in the soil, and organic carbon may be a limiting factor for growth of soil bacteria. Thus, it can be expected that these co-vary at different scales in the soil. In this thesis, I have studied the spatial interaction between soil bacteria and natural and contaminant (polycyclic aromatic hydrocarbon, PAH) organic carbon. The o

Molar mass and molar mass distribution of polymers are parameters of fundamental importance as they influence the performance of the polymer in applications. Polysaccharide derivatives are a class of polymers that have attracted significant scientific and commercial interest as they can be manufactured from a wide range of abundant sources in nature and thereby often are both cheap and biocompatib

Inhalation of air-borne microorganisms and components thereof can cause illnesses and diseases. However, lack of specific and sensitive methods for exposure assessment can pose problems in predicting health outcomes. Characterization of microbial load from indoor environments using gas chromatography-mass spectrometry (GC-MS) and/or tandem mass spectrometry (GC-MSMS) as well as various bioassays (

A number of homo- and heterodinuclear complexes have been synthesized as structural and functional models for the the active sites of phosphoesterases and soluble methane monooxygenases. The complexes are based on four new dinucleating ligands containing a central, potentially bridging, phenolate moiety. The hydrolytic activity of the complexes was examined by exploring the ability of the complexe

The thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. Measurements: · Absolute lung volume was obtained with a tracer gas method (sulfur hexaf

Using computer-assisted sequence homology searches we identified three genes encoding proteins similar to certain fusion partner proteins in cancer. The novel APRIL gene was localized to 15q25 and encodes a protein, containing an acidic amino-acid region similar to that/those of leukemia-associated fusion partner proteins DEK and SET. The N-terminus of APRIL contains leucine-rich repeats. The mous

Many individuals spend a substantial portion of their waking time thinking about topics unrelated to current activities and surroundings (mind wandering). This dissertation sought to contribute to our knowledge of why some people mind wander more than others. Mind wandering in cognitive tasks is more common in individuals with poor executive cognitive control (working memory updating, inhibiting t

The aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. The results showed that monovalent salt only slightly increases the hydrophob

Asthma is a common disease, characterized by periods of bronchoconstriction of unclear origin. This thesis examines a specific behavior of airway smooth muscle, the so-called spontaneous airway tone. It was suspected that a defect regulation of this tone may be a cause of asthmatic bronchoconstriction. The experiments shows that tracheal preparations can display two types of spontaneous tone. In t

Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. The distribution will be more or less heterogeneous both due to the fact that polymers from renewa

This work has been aimed at developing and applying laser-induced incandescence (LII) for flame soot characterization. The basic principle of LII is rapid heating of the soot particles to temperatures of 3500-4000 K by short laser pulses. Thereby the intensity of the soot incandescence is increased. By detection of this increased incandescence and analysis of the detected signal, the volume fracti

Optical spectroscopy is a versatile and powerful tool to probe translucent materials. In this work, the focus is on characterization of strongly scattering (turbid) materials by means of time-of-flight spectroscopy (TOFS). Instrumentation and modelling aspects of TOFS were investigated and improved, enabling significantly more accurate spectroscopic measurements. It was shown that the commonly us

IntroductionThis study is part of an international collaboration that investigates teachers’ attitudes and responses to vignettes depicting school bullying situations. As per Bandura's model of reciprocal determination, attitudes and behavior in these situations can be influenced by individual and contextual factors. This study specifically examines several factors related to teachers ‘professiona

In Sweden there are many people who take the food on our tables for granted, there is rarely anyone who reflects on the fact that it was hard work behind. The situation has not always been like that. During the late 1800s there were still many people living in rural areas and their livelihood was farming. Their jobs and mundane chore was to produce, if not the whole, but parts of the food that wou
