The spectral induced polarization (SIP) method is a promising method for many near surface applications, including characterization of contaminated soil. In this study, SIP measurements, high-resolution X-ray tomography and image analysis are combined to investigate clean and tetrachloroethylene (PCE) contaminated sand. This is the first known combination of these methods and the aim of this paper
The precise characterization of femtosecond laser pulses is as challenging as their generation and a topic of intense research. Dispersion-scan (d-scan) [1] is a recently established technique where the spectrum of a nonlinear signal, e.g., second-harmonic generation (SHG), is measured as a function of dispersion applied to the pulse. The spectral phase of the pulse can then be retrieved from the
Recent developments in drilling technology have resulted in about five to ten times faster penetration rates compared to penetration rates of conventional diamond drilling. The increased penetration rates open up for affordable drilling of deep boreholes in regions with cold crust, such as in Scandinavia, allowing for geothermal energy generation in enhanced geothermal systems. We present two infr
Objectives: The progression and pathophysiology of neuropathy in impaired glucose tolerance (IGT) and type 2 diabetes (T2DM) is poorly understood, especially in relation to autophagy. This study was designed to assess whether the presence of autophagy-related structures was associated with sural nerve fiber pathology, and to investigate if endoneurial capillary pathology could predict the developm
The bone material from three archaeological occupation phases at Huseby Klev provides the best source of evidence currently available about the subsistence strategies of pioneer settlers in Northern Europe. The results from Huseby Klev indicate that the pioneer settlers initially relied heavily on marine mammals for their sustenance. This subsistence strategy changed during the second and third oc
The aim of this study is to increase our understanding of the attitudes towards the scientific search for extraterrestrial life among high school and university students in Sweden. The most important results of the analysis are that: (a) the great majority of students believe that extraterrestrial life exists; (b) most students regard searching for extraterrestrial life to be quite important or ve
This article will present and discuss the process of digital co-production and audiences' responses to the full-scale interactive, gestural, visual and musical experience of a Virtual Reality arts play. This was inspired by cist-slab images from the Kivik Grave, which is Sweden's most famous Bronze Age grave. The aim of the VR arts play was to use digital technology to engage users as time-travell
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
Specific granule protein of 28 kDa (SGP28), also termed cysteine-rich secretory protein 3 (CRISP-3), is a glycoprotein that belongs to a family of cysteine-rich secretory proteins (CRISPs). SGP28 was originally discovered in human neutrophils, but transcripts are widely distributed in exocrine glands (salivary glands, pancreas, and prostate) and also found at lower levels in epididymis, ovary, thy
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
A rapid and sensitive assay was developed for the detection of amphetamine in plasma and urine. The method relies on the principle of competitive ELISA (enzyme-linked immunosorbent assay). A flow microchip with a total volume of 7 µL was used for the development of a chemiluminescent ELISA technique. Solutions, samples, and the chemiluminescence substrate were injected by a flow system, and a phot
We consider all two times iterated Ito integrals obtained by pairing m independent standard Brownian motions. First we calculate the conditional joint characteristic function of these integrals, given the Brownian increments over the integration interval, and show that it has a form entirely similar to what is obtained in the univariate case. Then we propose an algorithm for the simultaneous simul
OBJECTIVE: The study was undertaken to measure baseline values for chemical markers in human subjects during wakefulness, anesthesia, and neurosurgery, using intracerebral microdialysis. METHODS: Microdialysis catheters were inserted into normal posterior frontal cerebral cortex in nine patients who were undergoing surgery to treat benign lesions of the posterior fossa. The perfusion rate was 1.0
The aim of this study is to investigate the degree of job satisfaction, burnout and strain among nurses (n=134) working in three care units for demented people in southern Sweden. Three questionnaires were used: the Maslach burnout inventory (MBI), the work-related strain inventory (WRSI), and a recently developed measure for assessing job satisfaction. Based on principal component analysis, an ei
A pool of heparan sulphate-binding proteins (HSBPs) from Helicobacter pylori culture supernates was obtained by sequential ammonium sulphate precipitation and affinity chromatography on heparin-Sepharose, The chromatographic procedure yielded one major fraction that contained proteins with heparan sulphate affinity as revealed by inhibition studies of heparan sulphate binding to H. pylori cells. P
Specific antiarrhythmic therapy with class I and III drugs for atrial fibrillation (AF) conversion and prevention of its recurrence is frequently utilized in clinical practice. Besides being only moderate effective, the utilization of antiarrhythmic drugs may be associated with serious side effects. In the clinical setting it is difficult to directly evaluate the effects of antiarrhythmic drugs on
