Physiology of Industrially Relevant Bacteria: Freeze-drying tolerance of Lactobacillus reuteri and Pseudomonas chlororaphis and product formation of Lactococcus lactis metabolizing maltose

When the metabolic activity of bacteria is exploited by the food and biotechnology industries, freeze-drying is commonly used to produce concentrated bacterial cultures with enhanced storage stability. The freeze-drying tolerance of the probiotic strain Lactobacillus reuteri and the biocontrol agent Pseudomonas chlororaphis has been characterized in this work. Lb. reuteri was found to have higher

Exterior Colours at Rural Dwellings in Southern Sweden during the 19th Century - To increase knowledge regarding local differentiations

Abstract The project’s main objective is to verify the existence of local colours and colour schemes in the exteriors of buildings. The research focused on 19th century dwellings in the rural areas of southern Sweden. The results and furthermore the conclusions are presumed to reveal locally differentiated colours used and to indicate rules governing the way in which the colours were combined duri

Euroscreen: The attraction of screen destinations. Baseline report assessing best practice

EuroScreen is a project specifically designed to capitalise on the major economic and cultural opportunities presented through screen tourism. The three year project, co-financed by the European Regional Development Fund and made possible by the INTERREG IVC programme, aims to exploit the screen sector as a proven catalyst for tourism development through the alignment of policies between the scree

Visible and radar observations of the Perseid meteor stream 1953-83

This paper describes a long term, high-resolution study of the activityof the Perseid meteor stream based on visual and radar observations atthe Onsala Space Observatory in Sweden. The data consists of 147 visualhourly rates and 1368 radar hourly rates. In a previous paper (Lindblad2000) a high-resolution study of the visual zenithal hourly rates ofbright Perseid meteors versus solar longitude was

Effects of Oral Contraceptives on Endogenous Hormones, Body Constitution, and Breast Epithelium in Healthy, Young Women

This thesis concerns the effects of low-dose oral contraceptives (OCs) on endogenous hormones, insulin-like growth-factor-1 (IGF-1), sexual hormone binding globulin (SHBG), and body constitution in two groups of healthy women aged 19­25 who had never been pregnant. Prolactin concentrations were elevated in a subgroup of present and former users. IGF-1 concentrations were significantly decreased du

Flernivådemokrati : en teoretisk såväl som praktisk utmaning

Under de senaste decennierna har nationella politiska system gått från att vara hierarkiska och territoriellt välavgränsade till att bli såväl flernivåbaserade som gränsöverskridande. Detta har onekligen haft konsekvenser för demokratin. Med utgångspunkt i den svenska utvecklingen problematiserar vi, i denna rapport, kort begreppet flernivådemokrati och studerar dess eventuella förtjänster och bri

Effects of increased UV-B radiation on the lichen Cladonia arbuscula spp. mitis: UV-absorbing pigments and DNA damage

Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. However, in the last two decades, due to the depletion of the stratospheric ozone layer, increasing levels of ultraviolet-B radiation (280-3

On the Role of Polyamines in Apoptosis

Popular Abstract in Swedish Reglering av celltillväxt och celldöd är mycket viktigt för bibehållandet av balansen mellan antalet olika celler i kroppen. Om regleringen rubbas kan olika sjukdomar uppkomma, som karakteriseras av för mycket celltillväxt eller av för mycket celldöd. Exempel är cancer, där man har för mycket tillväxt, samt många degenerativa sjukdomar som diabetes, Parkinsons och aids,Apoptosis is a kind of death that is best described as cellular suicide and it is important for normal tissue homeostasis. The process can be induced by a number of different stimuli and the dying cell goes through a defined pathway terminating in typical biochemical and morphological alterations of the cell. With my studies I wanted to investigate the role of the polyamines in the regulation of a
