Calcareous soils are frequently characterized by the low bioavailability of plant nutrients. Consequently, many vascular plant species are unable to successfully colonize calcareous sites and the floristic composition of calcareous and acid silicate soils has been shown to differ markedly. The root exudation of oxalate and citrate has been suggested to play a pivotal role in same nutrient acquisit
Objective: This paper analyzes some of the problems with error counting as well as the difficulty of proposing viable alternatives. Background: Counting and tabulating negatives (e.g., errors) are currently popular ways to measure and help improve safety in a variety of domains. They uphold an illusion of rationality and control but may offer neither real insight nor productive routes for improvin
Aims and objective. To evaluate patient- reported health outcomes of a multidisciplinary group educational programme for people with Parkinson's disease ( PD), delivered as part of routine clinical practice. Background. Studies suggest that educational programmes for people with PD have potential to improve patients' perceived health and well- being. However, controlled trials of multidisciplinary
We present the details of an experiment on light particle interferometry. In particular, we focus on a time-of-flight technique which uses a cyclotron RF signal as a start and a liquid scintillator time signal as a stop, to measure neutron energy in the range of En approximate to 1.8-150 MeV. This dynamic range (up to 300 ns) is much larger than the beam bunch separation (54 ns) of the AGOR cyclot
A number of screening procedures are offered by midwives during pregnancy and the number is increasing rapidly. The measurement of nuchal translucency is a fairly new ultrasound method for antenatal screening, primarily for Down syndrome. The results give a better risk calculation than maternal age alone and can mean a decrease in the number of invasive procedures needed to identify this syndrome
Element cycling and nutrient supply in forest ecosystems are of vital importance for short-term productivity and for longer-term land management in terms of nutrient leaching and CO2 fixation. This thesis includes a series of studies with the objective of modelling some aspects of the effect of acidification and climate change on element cycling and nutrient supply in forest soil. A reconstructio
Popular Abstract in Swedish Klumpfot är en medfödd fotfelställning, som drabbar 1 av 1000 barn. Behandlingen består initialt av korrektion av felställningen, genom töjning och eventuellt operation. Det finns flera alternativa metoder att genomföra töjningar, och flera alternativa operationsmetoder. När felställningen korrigerats övergår behandlingen till att bibehålla det uppnådda läget med hjälp Clubfoot is a congenital disorder, affecting about one of 1000 children. Treatment consists of initial correction of the deformity, followed by prolonged orthosis treatment to maintain the correction obtained. There are several different treatment options. Outcome studies, using reliable and valid instruments are rare. In this thesis an assessment instrument, Clubfoot Assessment Protocol (CAP) wa
Ambient solar radiation effects on Phragmites australis leaf and culm litter were investigated in a shallow and eutrophic south Swedish lake littoral. Leaf and culm litter was exposed to natural sunlight in the lake at a water depth of a few centimeters. For the leaf litter, an additional subset of the experiment was exposed to solar radiation in the air, to evaluate effects of the solar radiation
Total and 0.2 M HCl-soluble concentrations of 44 mineral elements were studied in four profiles (0-110 cm) of a Haplic Podzol, developed from a 13,000-14,000-year-old quartzite-gneiss moraine deposit in south Sweden. Depending on element and soil fraction of the element considered, concentration maxima occurred in different horizons in the soil. The E horizon was impoverished in HCl-soluble fracti
A pairwise comparison of the nucleic acid sequence of 168 bases from 152 wild-type or unique cell culture-adapted strains of hepatitis A virus (HAV) revealed that HAV strains can be differentiated genetically into seven unique genotypes (I to VII). In general, the nucleotide sequence of viruses in different genotypes differs at 15 to 25% of positions within this segment of the genome. Viruses from
The achievement of a sustainable society is ultimately an educational enterprise. E-learning has a role to play in this endeavour, as it permits global access to environmental education, independent of time and place,once the courses are available on the Internet. Besides reaching new target groups not able to attend higher education on campus, e-learning may potentially be a more resource efficie
Occurrences of fire ignitions in a given region during a specified period of time are modelled as outcomes of a Poisson point process. The ignition frequency is considered a function of the total floor area of the building. Parameter estimates and their uncertainties are computed. Different criteria for model selection are used. The proposed methodology is specifically useful in the case with smal
Objective: To investigate the associations between psychosocial conditions at work, social capital/social participation, and daily smoking. Design/setting/participants/measurements: The 2000 public health survey in Scania is a cross sectional postal questionnaire study with a 59% participation rate. A total of 5180 persons aged 18–64 years that belonged to the work force and the unemployed were i
We compared the efficiency of some commercially available products and methods used for remediation of mould-contaminated building materials. Samples of gypsum board and pinewood were artificially contaminated with toxin-producing isolates of Stachybotrys chartarum and Aspergillus versicolor, respectively, then, ten different remediation treatments were applied according to the manufacturers' inst
Diamond-Blackfan anemia (DBA) is a congenital erythroid hypoplasia caused by a functional haploinsufficiency of genes encoding for ribosomal proteins. Recently, a case study reported a patient who became transfusion-independent in response to treatment with the amino acid L-leucine. Therefore, we have validated the therapeutic effect of L-leucine using our recently generated mouse model for RPS19-
