Calcareous soils are frequently typified by a low availability of plant nutrients due to poor solubility of these elements at high pH. Calcicole plants have recently been shown to release organic acids in response to the nutrient deficient conditions prevailing in these soils. It has been speculated, however, that the efficiency of this nutrient mobilization mechanism may be significantly reduced

Recent multi-configuration Hartree-Fock (MCHF) calculations of atomic hyperfine structures are reviewed. In particular, spin-polarization and relativistic effects are considered. Using a systematic active space MCHF approach, combined with large multi-reference configuration interaction (MR-CI) calculations, it is shown that hyperfine structures in many cases can be calculated very accurately. For
The threatened estate - the memorails of Per Brahe junior On the background of the present research on memorials and monuments follows a study of a number of memorials erected by the count Per Brahe junior between 1653 and 1680 on Visingsö and in Skärstad in Småland, at Dimbo in Västergötland and Östra Ryd in Uppland. The memorials belong to a period, when his county Visingsborg in Sweden and baro
BACKGROUND.: To better define subpopulations in which achieving adequate mycophenolic acid (MPA) concentrations quickly would be important, a post hoc exploratory analysis on the fixed-dose concentration-controlled database was performed, comparing high- versus low-risk renal transplant patients. METHODS.: Renal transplant patients were treated with mycophenolate mofetil, corticosteroids, and cycl

Research on incompetent humans raises ethical challenges, especially when there is no direct benefit to these research subjects. Contemporary codes of research ethics typically require that such research must specifically serve to benefit the population to which the research subjects belong. The article critically examines this "same-population condition", raising issues of both interpretation and
Popular Abstract in English Most of us are familiar with using plant-derived material such as wood for producing heat for warming the cottages or cooking food when we are camping. Apart from that, plant-derived materials such as trees, forest residues, grasses, agricultural crops, agricultural residues and straw have great potential in producing energy in a larger scale. This group of material is In this thesis, a numerical approach is adopted to study biomass thermochemical conversion. Detailed physical and chemical processes involved in the thermochemical conversion of biomass are considered. The aims are to improve the understanding of the physical and chemical processes involved and to develop and validate mathematical models for numerical simulation of the biomass conversion process.
Context: The diagnosis of late-onset hypogonadism (LOH) in older men with age-related declines in testosterone (T) is currently not well characterized. Objective: Our objective was to investigate whether different forms of hypogonadism can be distinguished among aging men. Design: The study was a cross-sectional survey on 3369 community-dwelling men aged 40-79 yr in eight European centers. Methods
This article explores how we can understand contemporary participatory online encyclopaedic expressions, particularly Wikipedia, in their traditional role as continuation of the Enlightenment ideal, as well as in the distinctly different space of the Internet. Firstly we position these encyclopaedias in a historical tradition. Secondly, we assign them a place in contemporary digital networks which
BACKGROUND: Sphingomyelin occurs in modest amounts in the diet, in sloughed mucosal cells, and in bile. It is digested by the mucosal enzymes alkaline sphingomyelinase and ceramidase. In humans, alkaline sphingomyelinase is also secreted in bile. The digestion of sphingomyelin is slow and incomplete, which has been linked to the inhibition of cholesterol absorption and colonic carcinogenesis. OBJE
New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). In recent years FPGAs have developed, from
OBJECTIVE: To assess the inter-tester reliability of the New Mobility Score in patients with acute hip fracture. DESIGN: An inter-tester reliability study. SUBJECTS: Forty-eight consecutive patients with acute hip fracture at a median age of 84 (interquartile range, 76-89) years; 40 admitted from their own home and 8 from nursing homes to an acute orthopaedic hip fracture unit at a university hosp
Popular Abstract in Swedish Den här avhandlingen handlar om utvecklingen av CARS som en diagnostikmetod för att studera förbränningsförlopp. CARS står för Coherent Anti-Stokes Raman spectroscopy och är en optisk laserbaserad metod för att mäta temperaturer och ämneskoncentrationer i gaser. CARS, och andra typer av förbränningsdiagnostikmetoder, bidrar till ökad förståelse för de processer som utgöDuring the last decades, coherent anti-Stokes Raman spectroscopy (CARS) has been an important tool in combustion research. The focus of this thesis is the improvement of the capability of the pure rotational CARS (RCARS) technique for this type of applications. The technique is used to measure temperatures and relative species concentrations in the gas phase and thermometry is performed by fitting
