Four qualitative methods for the detection of beta-lactamase production in Staphylococcus and Micrococcus species were evaluated and compared with a quantitative macroiodometric reference method. The disc diffusion test with penicillin G and the cloverleaf method could not separate beta-lactamase-positive from beta-lactamase-negative strains. Two applications of the chromogenic cephalosporin test,

A new Reynolds stress transport model (RSTM) aimed for engineering applications is proposed with consideration of near-wall turbulence. This model employs the Speziale, Sarkar and Gatski (SSG) pressure strain term, the omega equation, and the shear stress transport (SST) model for the shear stresses at the near-wall region (say, y(+) < 30). The models are selected based on the following merits: Th

Modern treatment decision making in medicine is recommended to be evidence based. In order to have a high grade of evidence, the studies should have sufficient power, be randomized and double blinded. Moreover, the evaluation parameters should be solid and reproducible. While there is a lot focus on primary study design much less is focused on patient eligibility and to what extent the patients in

Popular Abstract in Swedish Moderna tillverkningsmaskiner är dyra och därför måste dess tillgänglighet och effektivitet ständigt hållas högt. Sådana resultat kan man inte åstadkomma utan tillämpning av en effektiv underhållsstrategi. Förutsättningar för att minska eller arrestera förslitnings hastighet på maskins delar och öka maskinlivslängden är stora vid användning av tillståndsövervakning, (TÖModern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. The main result reported in this thesis is that the rolling element bearing’s mean effective li

Pelvic pain (acute or chronic) is a common symptom in women of all ages. Ultrasonography is the least invasive investigative tool available to the clinician. Transvaginal probes produce high-resolution images of the pelvic organs, providing reliable and reproducible information without the need for a full bladder. Common gynaecological pathology involving the uterus, Fallopian tube and/or the ovar

Aluminum interacts with negatively charged surfaces in plant roots, causing inhibition of growth and nutrient uptake in plants growing on acid soils. Pectins in the root cell wall form the major cation adsorption surface, with Ca2+ as the main adsorbing cation. Adsorption of Al3+ and Ca2+ to isolated cell wall material of tomato (Lycopersicon esculentum L.) roots was examined at pH 3.00-4.25 and i

The effect on intestinal macromolecular absorption capacity and immunoglobulin G (IgG) transfer of feeding sow colostrum at different intervals and in different quantities to newborn pigs was studied. An amount of 15 ml/kg body weight (BW) colostrum was fed at 3 (treatment 3-15), 6 (treatment 6-15) or 12 (treatment 12-15) h intervals, respectively, starting 0-4 h after birth for 24 h; or 30 ml/kg

The pharmacokinetics of antimigraine drugs zolmitriptan and sumatriptan varied considerably with a fourfold to 10-fold variation in plasma levels. In addition, the pharmacodynamics of triptans as investigated in vitro also varied considerably. In theory, there should probably be a 10-fold variation in doses available, but in clinical practice a fourfold difference in doses will probably cover the

Natural radiative lifetimes and LandégJ factors for several highly excitedF states in cesium were measured using time-resolved fluorescence spectroscopy. TheF states were excited from the 52D5/2 state with a pulse-modulated CW dye laser, and the delayed-coincidence method was employed to record decay curves, which in some experiments exhibited Zeeman quantum beats. A further CW dye laser was used

In this work, the interfacing of a poly(ethylene glycol) (PEG)-phosphate aqueous two-phase system with hydrophobic interaction chromatography (HIC) for primary recovery of an intracellular protein was evaluated. As a model protein, a recombinant cutinase furnished with a tryptophan-proline (WP) peptide tag was used and produced intracellularly in Escherichia coli (E. coli). E. coli cell homogenate

The atomic and electronic structure of the lattice-mismatched h-BN/Pt(111) and h-BN/Rh(111) interfaces formed by pyrolitic reactions with vaporized borazine has been studied by low-energy electron diffraction, scanning tunneling microscopy, x-ray-absorption spectroscopy, and core-level and valence-band photoemission. It has been found that on Pt(111), h-BN forms a nearly flat monolayer, insignific

The adapter protein APS has previously been shown to be involved in recruiting the ubiquitin E3 ligase c-Cbl to the insulin receptor, the platelet-derived growth factor b-receptor and the erythropoietin receptor, leading to increased degradation of the receptors and inhibition of mitogenesis. Here we demonstrate, by use of immobilized synthetic phosphopeptides corresponding to various autophosphor

Popular Abstract in Swedish Olika laserbaserade mätmetoder för diagnostik av förbränningsmotorrelaterade fenomen har utvecklats och demonstrerats, såväl utanför som i motorer. Följande områden har studerats: -Inverkan av inhomogen bränsle-/luftblandning på cykel-till-cykelvariationer hos förbränningen i en otto-motor studerad genom laserinducerad fluorescens (LIF) på bränslet. -Restgasers inverkanVarious laser diagnostic techniques have been developed and demonstrated for engine, or engine-related measurements. The experimental work is presented in Chapter 3 and in Papers I-VII. In Chapter 3, imaging of soot in a running compression-ignition (CI) is described. Four different approaches were applied with the aim of investigating the applicability of these approaches in a running engine. I

In an attempt to identify novel susceptibility genes predisposing to early-onset diabetes (EOD), we performed a genome-wide scan using 433 markers in 222 individuals (119 with diabetes) from 29 Scandinavian families with ≥2 members with onset of diabetes ≤45 years. The highest nonparametric linkage (NPL) score, 2.7 (P < 0.01), was observed on chromosome 1p (D1S473/D1S438). Six other regions on chr

While populism and populist politics have been the focus of a wide range of studies in the social sciences, few analyses of populist phenomena have moved beyond the level of simple description. This study has three immediate aims: to critique existing theories of populism, to develop a new, analytical view of populism, and apply this view comparatively to two cases. This new view of populism emer
