Microfungi represent an important part of the fungal flora in coniferous forest soils and they play a significant role in the decomposition processes. Common genera and species isolated at 3 sites in Sweden, 2 of which have well developed Fe podzol soil profiles are presented. Fungal isolations were made with a soil-washing technique from 5 soil horizons. Aureobasidium and Cladosporium were only i

Plasma autoantibodies (aAbs) against the oxidized DNA base derivative 5-hydroxymethyl-2'-deoxyuridine (5-HMdU) are potential biomarkers of cancer risk and oxidative stress. We examined their association with a number of cancer risk factors: smoking, alcohol habits, body fatness, and absence of the glutathione S-transferases M1 and T1 (GSTM1 and GSTT1) in a sample from the population-based Malmö Di

Implementation of an in-mill biological treatment plant is one solution to the problems associated with closure of whitewater systems. It is, however, important to operate the treatment with low concentration of nutrients in the effluent. The effect on the COD reduction from decreased additions of NH4-N and PO4-P were investigated in three parallel aerobic suspended carrier reactors during treatme

Blue (or green) light induced reversible and irreversible absorption changes in etiolated wheat (Triticum aestivum) coleoptiles. Immediately after a 10 s pulse of blue light, there was an absorbance increase at 440 nm and a decrease at 420 nm. The absorbance at 440 nm returned to the original level in a biphasic way with 1st-order rate constants of 0.05 s-1 and 0.006 s-1 at 25.degree. C. The chang

Relationships between cytosolic free calcium ([Ca2+]i) in platelets, indices of systemic calcium metabolism and blood pressure were examined in 86 subjects; 29 patients with untreated and 29 patients with treated essential hypertension, six patients with borderline hypertension and 22 healthy reference subjects. In order to analyse interactions between the variables, multivariate statistical analy

The work is composed of three parts: - (1) An overview of the concept moisture deign with regard to service life. (this report) - (2) A practical application of service life analysis applied to frost damage, based on materials testing. (this report) - (3) A theroretical analysis of methods for service life design of concrete and concrete structures exposed to internal frost damage (Report TVBM-04/

Object. Cerebral vasospasm following subarachnoid hemorrhage (SAH) leads to reduced blood flow in the brain. Inspired by organ culture-induced changes in the receptor phenotype of cerebral arteries, the authors investigated possible changes in the 5-hydroxytryptamine (HT) receptor phenotype after experimental SAH. Methods. Experimental SAH was induced in rats by using an autologous prechiasmatic i

This paper discusses the ethics underlying the occupational repertoire of the post-industrial citizen, giving attention to lifestyle phenomena such as increased tempo and quantity of occupations; manipulation of time, organisms and environments; decreases in sleep, rest and play etc. In trying to understand human behavior in the 21st century, an ethical perspective is delineated and some starting

Hemopoietic stem cells (HSCs) are maintained at relative quiescence by the balance between the positive and negative regulatory factors that stimulate or inhibit their proliferation. Blocking the action of negative regulatory factors may provide a new approach for inducing HSCs into proliferation. A variety of studies have suggested that TGF-beta negatively regulates cell cycle progression of HSCs

Performance of computer-based systems may depend on many different factors, internal and external. In order to design a system to have the desired performance or to validate that the system has the required performance, the effect of the influencing factors must be known. Common methods give no or little guidance on how to vary the factors during prototyping or validation. Varying the factors in a

Background: Iceland's geographical isolation with a stable and small population gives a rare opportunity for follow-up studies of medical interventions. Total hip replacements (THR) have been done at FSA Central Hospital in Akureyri, Iceland since 1982 with the Exeter hip implant being in use from the beginning. Methods: Hospital records for all patients operated on with THR between 1982 and the e

We examine how to reliably exploit baseline diversity of a multichannel interferometric synthetic aperture radar (InSAR) system to overcome the layover problem. In practice, the baseline steering vectors will be imprecise, resulting in array miscalibration. We propose, a nonparametric multilook approach based on robust Capon beamforming (RCB), allowing for uncertainty in the steering vectors.

We followed 11 patients 3-15 years after a cemented mega total hip replacement for a proximal femoral bone tumor. 7/8 survivors had good function and only occasional pain. 1 hip had been revised because of deep infection and in 1 case the cup had been exchanged because of aseptic loosening. 2 patients had been operated on because of local recurrence of the tumor. At follow-up, 1 patient had radiog

Objectives were to investigate prospectively the ability of DNA adducts to predict cancer and to study the determinants of adducts, especially air pollutants. DNA adducts were measured in a case-control study nested in the European Prospective Investigation into Cancer and Nutrition (EPIC investigation. Cases included newly diagnosed lung cancer (n = 115), upper respiratory cancers (pharynx and la

Background. Of the estimated one million Papanicolaou (pap) smears performed annually in Sweden, about 4% show any degree of abnormality. Approximately, 1% of these cases contain moderate or severe atypia (high-grade squamous intraepithelial lesions) and the rest contain low-grade atypia. Recommendations for the management of minor abnormalities vary in various parts of Sweden. Generally, a second

We derive stellar ages, from evolutionary tracks, and metallicities,from Strömgren photometry, for a sample of 5828 dwarf and sub-dwarfstars from the Hipparcos Catalogue. This stellar disk sample is used toinvestigate the age-metallicity diagram in the solar neighbourhood. Suchdiagrams are often used to derive a so called age-metallicity relation.Because of the size of our sample, we are able to q

In the present experiment we examined reality monitoring for socially sensitive and non-sensitive information relating to prejudice (negative and positive beliefs about an ethnic minority). At study, participants either imagined or perceived negative or positive attributes in connection with photographs of target individuals that clearly varied in ethnicity (non-western or western). At test, the t

The aim of this study is to examine the rewriting of the memoirs of the former pirate Alexander Olivier Exquemelin, Los Piratas de América, originally published in Amsterdam in 1678, which the Mexican writer Carmen Boullosa carries out in two recent novels: Son vacas, somos puercos and El médico de los piratas. In the light of Gérard Genette’s theory of hypertextuality this study deals with the fo
