When Sephadex beads (0.45mg/kg b.w) are instilled intratracheally into rats, a granulomatous alveolitis with giant cell formation and fibrosis occurs. Moreover, the events in the alveolar region are paralleled by an eosinophil-dominated peribronchitis/bronchiolitis and perivasculitis. Bronchoalveolar lavage (BAL) shows a very distinct feature with an early pronounced neutrophil increase, followed

New methodologies based on supercritical fluid extraction (SFE) have been developed for the determination of fat-soluble vitamins in processed foods. The results obtained so far indicate that SFE is well suited to extraction of fat-soluble vitamins from food products, although validation work is required to establish accuracy and precision. The vitamins investigated were A, E and beta-carotene, an

En enkätundersökning har genomförts bland brandingenjörer i Sverige med syftet att få information om detektionstider samt reaktions- och beslutstider vid en utrymning av tre olika lokaltyper; varuhus, restaurang och danslokal/nattklubb. Reslutaten kan ligga till grund för fortsatta studier för att bestämma partialkoefficienter för dimensionering av de gångvägar som används vid utrymning. Den ger o

Policies for handling cases of penicillin-non-susceptible Streptococcus pneumoniae (PNSP) in day-care groups vary between different counties in Sweden. The aim of this study was to evaluate the epidemiological effect of excluding PNSP-carriers from children's day-care centres (DCC). We followed the incidence in 14 DCC groups with ongoing PNSP-spread, by repeated group screens until no further case

The function of the mature polymorphonuclear neutrophil is dependent on its granules, each with its characteristic content of proteins. The granule proteins are formed at different stages during maturation of neutrophils from myeloblasts to segmented cells. The regulation of granule protein expression is controlled by a number of transcription factors, many of which are also essential for commitme

Conidiation in A. cichorii Nattras is reversibly stimulated by near UV radiation (NUV .apprx. 313 nm) and inhibited by blue light (.apprx. 450 nm) and apparently is a mycochrome-mediated process. After induction with plane-polarized NUV, blue light polarized perpendicularly to the NUV was more effective in counteracting the induction than was blue light polarized parallel to the NUV. Both the blue

New basis sets of the atomic natural orbital (ANO) type have been developed for the main group and rare gas atoms. The ANO's have been obtained from the average density matrix of the ground and lowest excited states of the atom, the positive and negative ions, and the dimer at its equilibrium geometry. Scalar relativistic effects are included through the use of a Douglas-Kroll Hamiltonian. Multico

Background: The " Lister family complex," an extensive Swedish family with autosomal dominant Parkinson disease, was first described by Henry Mjones in 1949. On the basis of clinical, molecular, and genealogic findings on a Swedish and an American family branch, we provide genetic evidence that explains the parkinsonism in this extended pedigree. Methods: Clinical methods included a detailed neuro

This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. The framework is based on projective geometry, which is the natural language for describing the geometry of multiple views. The affine and Euclidean geometries are rega

Glyceryl monooleate (GMO) and other unsaturated long-chain monoglycerides show peculiar phase behaviour characterised by the presence of one or more cubic liquid-crystalline phases. In the present study, hydrolysis of cubic lipid-water phases formed by GMO were determined. Human pancreatic carboxyl ester lipase (CEL), colipase-dependent lipase with colipase, human duodenal contents and rat pancrea

The aim of this study was to describe the types and extent of eating difficulties, the need for assistance when eating, the nutritional status and pressure ulcers in consecutive patients (n = 162) admitted for stroke rehabilitation over a period of 1 year. Structured observations and assessments of eating, nutritional status (subjective global assessment of nutritional status), pressure ulcers and

We have developed software, called UNHLATEXTM> KMORPH, for predicting particle morphology development under conditions of kinetic control. In order to accomplish this, one must first simulate the polymerization kinetics and as a result KMORPH has developed into a fairly complete model for seeded emulsion polymerization kinetics. The simulation takes into account both the aqueous phase and particle

We assessed the influence of timing of harvests on an age-structured population by altering the order of the harvest in relation to density-dependent recruitment and winter mortality. To analyze the effects of harvest timing on a general population of stream salmonids with five age-classes, we used three management strategies: no minimum size limits and two minimum size limits with increasing degr

Popular Abstract in Swedish Under de senaste årtiondena har både kraftsensorer och digitala kameror kommit att bli vanliga som sensorer i olika robotiktillämpningar. Denna avhandling behandlar olika problem inom visuell rörelseskattning och återkoppling, samt integrationen av dessa tekniker med reglering av kontaktkrafter för en industrirobot. Olika ämnen tas upp, från grundläggande teori till praOver the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. Different topics ranging from basic theory to system implementation and applications are treated. A new interface develo

First, in the absence of pair correlation the properties of one-particle orbits of neutrons in nuclei close to the neutron drip line are briefly reviewed for both weakly bound neutrons and the neutrons in the continuum. The low-lying states in the continuum, which are close to the Fermi level, are of immediate importance for pair correlation and deformations of those nuclei. Then, the Hartree-Fock

Denna litteraturstudie utgör andra etappen i ett licentiatarbete om utbytbarhet, material- och energiflöden för installationer i byggnader (Orsaker till byte av VVS-installationer; TABK--01/1020).

The mobilization of fat stored in adipose tissue is mediated by hormone-sensitive lipase (HSL) and the recently characterized adipose triglyceride lipase (ATGL), yet their relative importance in lipolysis is unknown. We show that a novel potent inhibitor of HSL does not inhibit other lipases. The compound counteracted catecholamine-stimulated lipolysis in mouse adipocytes and had no effect on resi
