Popular Abstract in Swedish Tungmetaller i kommunala avfallsupplagExtensive use of heavy metals in modern society influences routes followed by fluxes on the surface of the Earth. The changed flow paths may be harmful for the balance of biological systems at different levels, micro-organisms, human beings and whole ecosystems, since the toxicity of heavy metals is determined by their concentrations and chemical forms. The fluxes of cadmium in Sweden and especia

Background: In addition to their possible direct biological effects, plasma carotenoids can be used as biochemical markers of fruit and vegetable consumption for identifying diet-disease associations in epidemiological studies. Few studies have compared levels of these carotenoids between countries in Europe. Objective: Our aim was to assess the variability of plasma carotenoid levels within the c

I have used data, mainly from south of 62degreeN, collected within the Breeding Bird Survey and the Winter Bird Count (1975-2001) to describe the population development of the Goshawk Accipiter gentilis in Sweden. The data from the breeding season indicate a considerable population increase. The winter data show a stable population for the winters 1975/1976-1993/94, then six winters with lower val

Decisions regarding strategic software process improvement (SPI) are generally based on the management's viewpoint of the situation, and in some cases also the viewpoints of some kind of an SPI group. This may result in strategies, which are not accepted throughout the organisation, as the views of how the process is functioning are different throughout the company. This paper describes a method f

An algorithm for multiple sequence comparison was implemented in FORTRAN 77 for VAX/VMS in GCG-compatible format. The MULTICOMP program package includes several procedures with which one query sequence can be compared simultaneously to several DNA, RNA or amino acid sequences. The same technique was also introduced for comparing propensities of secondary structural features, which can be predicted

A series of mono and bis -amino alcohols derived from phenylalanine were synthesised and their application as chiral catalysts in the asymmetric ethylation of aromatic aldehydes in the presence of diethylzinc investigated.

In the early postnatal period, the permeability of the piglet small intestine is high to compensate for the absence of trans-placental transfer of immunoglobulins during the fetal period. Vesicles, which mainly reflect the uptake of macromolecules and other colostral/ milk components, were studied in three different regions of the small intestine - proximal, mid and distal - in a total of twelve p

One of todays great issues is how an advanced medical technology like xenotransplantation should be applied. It is well known that medicine brings not only potential but also risk. On the cultural level, xenotransplantations are equally complicated; they arouse thoughts about whether our outlook on humanity will be influenced now that modern techniques can correct our defective bodies. The article

The identification of genes underlying quantitative-trait loci (QTL) for complex diseases, such as rheumatoid arthritis, is a challenging and difficult task for the human genome project. Through positional cloning of the Pia4 QTL in rats, we found that a naturally occurring polymorphism of Ncf1 (encoding neutrophil cytosolic factor 1, a component of the NADPH oxidase complex) regulates arthritis s

The immune-modulating cytokine interleukin-6 (IL-6) its expressed both in adipose tissue and centrally in hypothalamic nuclei that regulate body composition. We investigated the impact of loss of IL-6 on body composition in mice lacking the gene encoding IL-6 (116(-/-) mice) and found that they developed mature-onset obesity that was partly reversed by IL-6 replacement: The obese 116(-/-) mice had

This paper presents a new method to obtain porosity in apatitic cements, by mixing a-tricalcium phosphate (alpha-TCP) with calcium sulphate hemihydrate. The material was characterized by X-ray diffraction and observations in Electron Microscopy. The results show that crystals of calcium sulphate stayed embedded in the hydroxyapatite formed from a-TCP. By dissolution of these crystals porosity coul

Skalmur med bakomliggande träregelstomme är idag en av de vanligaste yttervägskonstruktionerna i Sverige. I allmänhet fungerar konstruktionen bra. Det finns dock många exempel på skador som beror på brister i fuktsäkerheten. I denna skrift beskrivs olika fuktbelastningar och vilka problem som kan uppstå. Varje detalj i konstruktionen beskrivs ur fuktteknisk synvinkel. Olika åtgärder för att förbä
