Reduction of energy use in buildings is fundamental for sustainable development. A computer program for the prediction of energy use in buildings was assessed by comparisons with the energy performance of existing buildings. The program was then used to evaluate the energy saving characteristics of concrete such as air tightness and heat capacity. The impacts on global environmental aspects and li
Objective: To investigate the potential of acetic acid supplementation as a means of lowering the glycaemic index (GI) of a bread meal, and to evaluate the possible dose - response effect on postprandial glycaemia, insulinaemia and satiety. Subjects and setting: In all, 12 healthy volunteers participated and the tests were performed at Applied Nutrition and Food Chemistry, Lund University, Sweden.
A control diet without supplemental fat and four diets containing 8% of coconut oil, rapeseed oil, fish oil or sunflower oil were fed to lactating sows in order to investigate the lipid absorption capacity of their progeny in terms of pancreatic enzyme activity, hormonal regulation, and bile salt concentration. In addition, the effect of age was studied during the four week suckling period, and du
Hyperplasia of middle-ear mucosa (MEM) during otitis media (OM) is thought to be partially mediated by the actions of growth factors and their receptors. The intracellular pathway leading from the small G-protein Ras to the extracellular regulated kinases (Erks) often links growth factor stimulation to cellular proliferation. This study assessed whether this pathway is involved in MEM hyperplasia
Cytogenetic aberrations have been reported in 45,000 human neoplasms. Structural balanced rearrangements are associated with distinct tumor subtypes with remarkable specificity and have been essential for identifying genes involved in tumorigenesis. All balanced rearrangements that have been characterized molecularly act by deregulating a gene in one of the breakpoints or by creating a fusion gene
Rome in Sweden? The Catholic Offensive in Ecumenical-National Context Since World War II, ecumenical principles have been used as historical measures. This has led to re-interpretations of historical events and to alterations of sources, for example the letters and diaries by Elisabeth Hesselblad, the renewer of St. Birgitta’s order. In the literature on the Swedish Archbishop Nathan Söderblom, th
The hydrophilic/hydrophobic properties of the membrane material have an important influence on the membrane flux reduction when treating solutions containing hydrophobic solutes. Different methods of measuring the hydrophobic properties of membranes have been evaluated; measurement of the contact angle being the most commonly used method. In this investigation the flux reduction of eight membranes
Popular Abstract in Swedish Denna studie behandlar huvudsakligen hur företagen väljer att anpassa sig till myndigheternas krav utifrån miljöskyddslagen. Undersökningen fångar en viss historisk tidpunkt då lagstiftning och myndigheter har en viktig betydelse. Det är en mycket dramatisk fas av den miljöekonomiska utvecklingen. I samhället har man inte tidigare artikulerat miljökraven på ett sådant sThis study primarily focuses on the ways in which companies choose to adapt themselves to the demands of the authorities as based on the Swedish environmental protection act. The time during which the burden upon nature became a serious, important question for companies is a very dramatic phase of a historical process. Before the arrival of more comprehensive legislation, no loads upon nature were
The anaerobic fermentation of deproteinized whey with beta-galactosidase coimmobilized with Saccharomyces cerevisiae in calcium alginate gel beads for the production of ethanol has been studied in a continuous horizontal packed bed reactor (HPBR). The results are compared with batch experiments in a stirred tank reactor. The immobilized yeast cells are exposed to conditions that vary with time and
1. The effects of antimalarial drugs on the intracellular signaling leading to activation of the phospholipase C and phospholipase A2 pathways and the induction of proinflammatory cytokines have been studied in mouse macrophages. 2. Both chloroquine and quinacrine, and to a lesser extent hydroxychloroquine, inhibited arachidonate release and eicosanoid formation induced by phorbol diester. This in

Popular Abstract in Swedish Konstant produktion av blodceller i benmärgen krävs för att bibehålla normal syretransport i blodet, sårläkning och ett effektivt immunförsvar. Bakom denna produktion ligger hematopoetiska blodstamceller som regleras av en komplex interaktion mellan dem och deras omgivning. Varje blodstamcell kan med självförnyande celldelningar, där minst en dottercell bibehåller en stHematopoietic stem cells (HSC) are sufficient and required for life long production of all blood cell lineages. Steady state HSCs are largely quiescent and we demonstrate that the kinetics of HSC cell cycling are slower compared to more committed progenitor cells also during expansion and self-renewal ex vivo and in physiological conditions. Such slow kinetics during cell division might reflect a
Background. Artificial neural networks have successfully been applied for automated interpretation of myocardial perfusion images. So far the networks have used data from the myocardial perfusion images only. The purpose of this study was to investigate whether the automated interpretation of myocardial perfusion images with the use of artificial neural networks was improved if clinical data were
The use of membrane-based extractions are increasingly seen as offering an alternative to conventional sample preparation procedures in analysis of chemical species in both food and agricultural samples. In this article, emphasis is placed on the attractiveness of membrane based extraction techniques to a variety of food and agricultural samples such as circulating nutrient solutions, fruit juices
Aim: To investigate the association between the use of cellular or cordless telephones and the risk for salivary gland tumours. Methods: Cases were assessed from the six regional cancer registries in Sweden. Four controls matched for sex and age in five year age groups were selected for each case. A total of 293 living cases and 1172 controls were included. Results: There were 267 (91%) participat
