The images of commercial potato chips were evaluated for various colour and textural features to characterize and classify the appearance and to model the quality preferences of a group of consumers. Features derived from the image texture contained better information than colour features to discriminate both the quality categories of chips and consumers' preferences. Entropy of a* and V and energ

Popular Abstract in Swedish Arbete är centralt i det moderna samhället. Samtidigt står många människor av olika anledningar utanför den ordinarie arbetsmarknaden. Att detta i särskild utsträckning gäller personer med funktionshinder har i många länder fått till följd att lagstiftning antagits för att på olika sätt öka arbetskraftsdeltagandet för denna grupp. De bestämmelser som reglerar arbete ochThis doctoral thesis examines labour market legislation on disability and work in Sweden, England and Germany. In order to provide increased access to the labour market for people with disabilities all three studies countries have undertaken more of less far-reaching legislative measures over a number of decades, both in line with, or as a result of, general labour and employment legislation, but

Two natural glycoproteins/glycoenzymes, invertase and glucoamylase, and two neoglycoconjugates, synthetized from Saccharomyces cerevisiae mannan, bovine serum albumin and penicillin G acylase were tested for interaction with lectin Concanavalin A (Con A). The interaction of natural and synthetic glycoproteins with Con A was studied using three different experimental methods: (i) quantitative preci

A numerical algorithm is presented for the problem of a crack along the interface of an elastic inclusion embedded in an elastic plane subjected to uniform stress at infinity. The algorithm is based on a Fredholm integral equation of the second kind and allows for fast and accurate solutions to geometries of great complexity. In an example crack opening displacement and stress intensity factors ar

The effect of detritus originating from different plant species on denitrifying capacity was investigated in a Swedish wastewater treatment wetland. Intact sediment cores containing sediment with a detritus layer were collected from wetland basins dominated by Typha latifolia, Phragmites australis, or Elodea canadensis in November 2000 and potential denitrification was measured using the acetylene

Summary Many competitive breath-hold divers use 'glossopharyngeal insufflation', also called 'lung packing', to overfill their lungs above normal total lung capacity. This increases intrathoracic pressure, decreases venous return, compromises cardiac pumping, and reduces arterial blood pressure, possibly resulting in a syncope breath-hold divers call 'packing blackout'. We report a case with a bre

b1 integrins are thought to play a central role in maintaining lymphocytes within mucosal epithelia via their interactions with extracellular matrix proteins and subepithelial cellular components within and underlying the basement membrane. In the current study type a (CD8abTCRab) and type b (CD8aaTCRcd and CD8aaTCRab) intraepithelial lymphocyte (IEL) subsets within the mouse small intestine were

A lab-scale continuous microalgal culture was grown on sterile-filtered wastewater in order to clarify the phosphorus removing mechanisms in a microalgal treatment step that treats residual phosphorus from a hydroponic wastewater treatment pilot plant. The phosphorus assimilation was dependent on algal biomass production, whereas the chemical precipitation was dependent on phosphorus load, i.e. an

The purpose of the present study was to investigate the amplifying function of the nucleus accumbens septi region (NAS) in 6-hydroxydopamine (6-OHDA)-induced rotational behaviour by implanting fetal dopamine (DA)-rich mesencephalic cell suspensions unilaterally in the NAS of rats previously subjected to combined mesostriatal (MS) and NAS 6-OHDA lesions. First, all the rats received a unilateral 6-

Recent research has improved the possibilities of assessing the influence of various factors on wound healing. Thus, PH. SANDBLOM (1944)(4), PH. SANDBLOM and A. MUREN (1953, 1954)(6,7) and B. ZEDERFELDT (1957)(8) and others have elucidated the effect of technical, local and physiological factors on the rate of healing of skin wounds. It has been shown (e.g. by B. ZEDERFELDT (1957)(8)) that various

This is a case report of a contact allergic reaction on the face due to a skin cleansing product containing the amphoteric surfactant sodium cocoamphoacetate, occurring in an atopic woman with multiple contact sensitivities. Because of its weak irritant properties, this surfactant is widely used in cosmetic products intended to be used for sensitive skin, including products for intimate, and baby

Neurobehavioral deficits in neuromotor function, verbal memory, executive function and attention found in patients with schizophrenia and their relatives have been suggested to be liability indicators or predictors of schizophrenia. It remains uncertain which of these neurobehavioral deficits are components of the illness itself or characteristics associated with genetic risk for it. The purpose o

We examine the evolutionary stability of year-round residency in territorial populations, where breeding sites are a limiting resource. The model links individual life histories to the population-wide competition for territories and includes spatial variation in habitat quality as well as a potential parent-offspring conflict over territory ownership. The general form of the model makes it applica

Background: Chronic obstructive pulmonary disease (COPD) is characterized by incompletely reversible airflow obstruction associated with inflammation in which monocytes/macrophages are the predominant inflammatory cells. The only known genetic factor related to COPD is inherited PiZZ deficiency of alpha1-antitrypsin (AAT), an inhibitor of serine proteases. Methods: We investigated the basal and LP

Dimorphism in pollen colour is rare among flowering plants, but occurs in two geographically and morphologically distinct subspecies of Nigella degenii (Ranunculaceae). We evaluated the role of genotype-by-environment interactions in the maintenance of two pollen morphs within each of these subspecies. Morph frequencies in a number of populations were related to current habitat conditions, and an
