Some raw material characteristics were evaluated in three apple varieties cultivated in Southern Sweden, namely Kim, Mutsu and Jonagold. The study was undertaken to collect information in order to identify the effects of initial tissue properties on mass transport phenomena in general, and osmotic processing responses in particular. The texture profile analysis revealed cortex anisotropy of the th
Software inspection is an effective method to detect faults in software artefacts. Several empirical studies have been performed on reading techniques, which are used in the individual preparation phase of software inspections. Besides new experiments, replications are needed to increase the body of knowledge in software inspections. This paper presents a replication of an experiment, which compar
Self-desiccation occurs in all types of concrete due to the chemical shrinkage that takes place when water is attached to the cement. In High Performance Concrete the low porosity makes the effect of self-desiccation much more pronounced. This paper presents a summary of a Nordic Seminar on Self-Desiccation in Concrete held in Lund. For this purpose aspects of mix design, curing conditions, desicc
Transgenically modified potatoes with a large spread in amylose/amylopectin ratios were analysed both as tubers and in the form of isolated starch. Different microscopic techniques were used to study starch granules and tuber tissue. Starch gelatinisation properties and recrystallisation of amylopectin and amylose were studied by differential scanning calorimetry. Starch bioavailability and resist
Mild heat treatment of carrot slices as a pre-treatment for frozen storage was accomplished by exposure of slices to radiant heat to maximise thermal exposure of the cells at the surface while preserving the integrity of cells within the slices. Cell damage as a consequence of this treatment on texture was evaluated. Carrot slices treated for 7 s with radiant energy in the far-infrared region from
The title compounds, chlorotris(dimethyl sulfide-kappaS)platinum(II) hexafluorophosphate, [PtCl(C2H6S)3]PF6, and bromotris(dimethyl sulfide-kappaS)platinum(II) hexafluorophosphate, [PtBr(C2H6S)3]PF6, are isomorphous and are composed of [PtX(dms)3]+ complex cations (X = Cl and Br, and dms is dimethyl sulfide) and PF6- anions. The Pt atom is coordinated by three S atoms and one X atom in
In a search for new fungal compounds inducing apoptosis of the colon cancer derived cell line COLO-320, hormonemate (1) was purified from fermentations of an endophytic fungus isolated from living needles of a Pinus species. The producing strain was identified as Hormonema dematioides by microscopy and ITS rDNA sequence analysis. The structure of hormonemate was determined by spectroscopic methods

The steam pressure control loops in the drying section of a paper machine play an important role for the quality of the moisture content control. The steam pressure loops are essential for the effective use of advanced control schemes for the moisture control. From mathematical model building and experiments on industrial paper machines it is found that the dynamics from the steam valves to the st
Set yoghurts produced with seven different exopolysaccharide-producing starter cultures were subjected to sensory texture profiling including texture evaluation before and after a stirring procedure carried out by trained assessors. The microstructure of four selected yoghurts was investigated by confocal laser scanning microscopy with special focus on the distribution of exopolysaccharides (EPS)
Popular Abstract in Swedish Akut mellanöreinflammation (akut otitis media, AOM) är en av barnaålderns vanligaste sjukdomare och en av dem som oftast föranleder antibiotikabehandling. De flesta barn får bara någon enstaka AOM, men cirka 5% av dem som insjuknar drabbas sedan av upprepade infektioner (s.k. otit-benägna barn) och blir till ett problem både för patienten, dennes familj och samhället. DAcute otitis media (AOM) is one of the most common childhood diseases and the most common causes of antibiotic treatment in small children. Most children will experience one or two episodes of AOM during preschool age but some will suffer from repeated attacks, they will become otitis-prone. Complications with severe, sometimes fatal infections such as acute mastoiditis and meningitis are nowadays

Long term evaluation of an asymmetric CPC PV-thermal hybrid built for high latitudes, MaReCo (MaximumReflectorCollector), is performed in Lund, lat 55.7o, and this paper discusses output estimates and characteristics of the system. The output estimates are calculated using the MINSUN simulation program. To get the input for MINSUN, measurements were performed on two MaReCo prototypes. These measur
A biofilm is a complex and diverse aggregation of microorganisms at surface comprised of among different things a protective adhesive matrix of extracellular polymeric substance. Biofilm research represents a broad range of sciences joining efforts within an interdisciplinary field of research. This thesis deals with the modeling of biofilms using the most fundamental laws of physics; the conserva
The sequence differences within the 16S rRNA genes of Lactobacillus casei/paracasei and related species, Lactobacillus zeae and Lactobacillus rhamnosus, were investigated. Thirty-seven strains of mostly human or cheese origin were grouped by restriction endonuclease analysis (REA) of the total chromosomal DNA and by temporal temperature gradient gel electrophoresis (TTGE) of PCR-amplified 16S rRNA
Lactobacillus isolates from healthy Estonian and Swedish children were characterised by a lectin typing technique; 56 isolates from six species (L. acidophilus, L. paracasei, L. plantarum, L. fermentum, L. brevis and L. buchneri) were tested. The typing system was based on an agglutination assay with a panel of six commercially available lectins, which,were chosen on the basis of their carbohydrat
Heparan sulfate chains have been found to be associated with amyloid deposits in a number of diseases including transmissible spongiform encephalopathies. Diverse lines of evidence have linked proteoglycans and their glycosaminoglycan chains, and especially heparan sulfate, to the metabolism of the prion protein isoforms. Glypicans are a family of glycosylphosphatidylinositol-anchored, heparan sul
The extraction of red pigment and conductive matters from individual red beet tissue slices following pulsed electric field pretreatment of different durations was compared with a two dimensional bimodal Fickian diffusion model. The process appeared to be governed by two apparent diffusion coefficients, one slow and one fast. The values of these coefficients were independent of the duration of tre
