Micronutrient concentrations in foliage and stemwood (including bark) of six European tree species (Betula pendula Roth., Quercus robur L., Fraxinus excelsior L., Fagus sylvatica L., Tilia cordata Mill. and Picea abies (L.) Karst.) planted on the same type of soil at six sites in three different countries were studied. Micronutrient concentrations in foliage were considerably higher than in stemwo
The aim of this study was to assess persistent organochlorine pollutant (POP) levels in serum collected from children (11-15 years old) working and sometimes also living at the municipal waste-disposal site in Managua, located at the shore of Lake Managua, and in nonworking children living both nearby and also far away from the waste-disposal site. The influence of fish consumption was further eva
BACKGROUND: Leucocyte recruitment and inflammation are key features of high dose radiation-induced tissue injury. The inflammatory response in the gut may be more pronounced following radiotherapy due to its high bacterial load in comparison to the response in other organs. We designed a model to enable us to study the effects of radiation on leucocyte-endothelium interactions and on intestinal mi
There is growing interest in developing a conceptual understanding of the experience of balance in everyday life, from an occupational perspective. The purpose of this study was to gain insights about balance in the everyday lives of women with stress-related disorders. Data were gathered from 19 women who were past the first phase of recovery from a stress-related disorder and participated in one
Popular Abstract in Swedish Denna avhandling behandlar utvecklingen av den norsk-svenska freden mellan 1905-1940. Efterhand kom denna relation att närma sig Stabil Fred—ett förhållande karaktäriserat av avsaknaden av militärt våld, hot om militärt våld, och förväntningar på hot om militärt våld. Utvecklingen mot Stabil Fred smammanfaller delvis med den svenska demokratiseringen, och författaren uThis study concerns the development of Stable Peace between states in the modern anarchical international system. As a starting point for the inquiry the author argues that the prevalence of this type of interstate relationships—characterized by the mutual expectations that neither military violence nor threats thereof will be employed—may be seen as a fundamental challenge to the validity of prev
The development of the Asperger Syndrome (and highfunctioning autism) Diagnostic Interview (ASDI) is described. Preliminary data from a clinical study suggest that inter-rater reliability and test–retest stability may be excellent, with kappas exceeding 0.90 in both instances. The validity appears to be relatively good. No attempt was made in the present study to validate the instrument as regards
Regression testing is expensive and may consume much of organizations’ software development budgets. Thus, it is of interest to reduce the total time devoted to test execution by using test selection techniques. Many techniques have been proposed but few have been evaluated on real-world, large scale systems. In this paper we report on an empirical evaluation of using the class firewall regression
A large number of studies carried out on pupils aged 8–14 have shown that teachable agent (TA) based games are beneficial for learning. The present pioneering study aimed to initiate research looking at whether TA based games can be used as far down as preschool age. Around the age of four, theory of mind (ToM) is under development and it is not unlikely that a fully developed ToM is necessary to
The aim of this study was to investigate experiences of hassles and uplifts among women. One hundred working mothers were interviewed using the Target Complaints instrument. Content analysis, resulting in both qualitative categories and quantitative variables, was used. Working mothers' hassles were mainly generated by their social, temporal and doing contexts and illustrate the importance of cons
Using literature data on the gas phase reaction between free lanthanide atoms and carbon dioxide, we have found an isokinetic relation for seven of the twelve investigated elements with an isokinetic temperature, T-iso of 2500 +/- 330 K. This value is analyzed in the framework of the model of selective energy transfer, SET, indicating that metal-CO2 complexes are formed as pre-reaction states. The
Matrilin-2 is a member of the protein superfamily with von Willebrand factor type A-like modules. Mouse matrilin-2 cDNA fragments were expressed in 293-EBNA cells, and the protein was purified, characterized, and used to immunize rabbits. The affinity-purified antiserum detects matrilin-2 in dense and loose connective tissue structures, subepithelial connective tissue of the skin and digestive tra
Popular Abstract in Swedish Fram till början av 80-talet var det främsta sättet, för att ta fram ett material med en ny egenskapsprofil, att framställa en ny polymer. Att ta fram denna polymer tog både lång tid och stora kostnader i anspråk. Utvecklingen gick i stället mot att blanda redan kända polymerer och på så sätt kombinera deras individuella egenskaper. De flesta polymerer är inte blandbaraThe search for polymeric materials with new property profiles has stimulated a great interest into polymer blends and reactive processing. During recent years many new blends have reached the market. Although some of these are homogeneous mixtures of polymers, most commercial blends are composed of immiscible polymers, and contain two or more polymeric phases. The properties of such blends depend
This study reports on a study from 2008 of overall mobility patterns among older people and the mobility patterns of those in transition from a two person household to a one person household. The purpose of the study was to explore the mobility patterns of those in transition from a two-person household to a one-person household in relation to the overall patterns of mobility of the older people.
Degradation of vegetation and soil erosion has contributed to loss of biological productivity and land degradation in Iceland. This thesis focuses on spatial and temporal patterns of land degradation in Iceland from a geographical perspective both along short and long timescales. The activity of current degradational processes has been assessed by studying farmers' perception of the problem and co
An affinity-assay was developed that is based on the modulation of the diffusion coefficient of a redox-labelled hapten upon complementary recognition of the analyte leading to an increase of molecular weight and hence to a decrease of the diffusion coefficient. The slower diffusion is monitored by means of cyclic voltammetry. In order to demonstrate the feasibility of this assay format, recogniti
In humans, beta-alanine (BAL) and the neurotransmitter gamma-aminobutyrate (GABA) are transaminated by a single aminotransferase enzyme. Apparently, yeast originally also had a single enzyme, but the corresponding gene was duplicated in the Saccharomyces kluyveri lineage. SkUGA1 encodes a homologue of Saccharomyces cerevisiae GABA aminotransferase, and SkPYD4 encodes an enzyme involved in both BAL
