The instantaneous response models the rapid part of the interaction between electromagnetic fields and materials. From a physical point of view the instantaneous response is non-observable and from a mathematical point of view it constitutes the principal part of the Maxwell equations. In this paper, it is shown that the instantaneous response is not uniquely determined from a given set of values
Oscillator strengths for 57 U II lines in the region 3500-6700 Åhave been derived by combining new branching fraction measurements withrecently measured lifetimes. The lines combine six upper levels withnumerous low levels having excitation energies of 0-1.5 eV. The datainclude the U II line at 3859 Å, which is used forcosmochronology.
Real-time ultrasound was used in 654 consecutive pregnancies to obtain standard growth parameters for the fetal brain. Measurement of the width of the lateral ventricle (LVW) and hemisphere and their relationships to menstrual age, biparietal diameter, and birth weight were determined. The growth of the LVW was to a great extent independent of birth weight but dependent on menstrual age. Thirteen
Subcutaneous metastases from an oesophageal carcinoma were irradiated using different schedules. The results have to be evaluated with greatest caution but indicate that with the same CRE value, few fractions caused less skin reactions than several, and the size of the shoulder of the cell survival curve was of the order of 0.7 Gy.
Both the antibody affinity and the detectability of the label are essential in deciding the final characteristics of a heterogeneous immunoassay. This paper describes an approach to obtain a supplementary enhancement of the signal generated by using an enzyme label, e.g., by including the product of the enzymatic reaction in an additional amplification cycle during the detection step performed wit
The Parmeliaceae flora of the Nordic area is reviewed on the basis of literature, database, and herbarium sources. A list of 40 genera and 153 species in current use, with comments on their distribution and taxonomic remarks on some of the species, is presented.
The Scandinavian part of the NICHD study of successive small-for-gestational-age (SGA) births included 5722 parous women from Trondheim and Bergen (in Norway) and Uppsala (in Sweden). Study enrollment took place from January 1986 through March 1988. The aim of the main study was to investigate factors associated with inhibited intrauterine growth. This paper reports on the fetal, perinatal, and ne
In recent years the Swedish Police Force (SPF) have encountered greater demands on availability and 24/7 services when dealing with errands that are regarded as low priority compared to regular police work, e.g. collecting tips from the public. One attempt to meet these increasing demands was the development of a mobile communications platform that allowed the public to communicate easily with the
Popular Abstract in Swedish Denna doktorsavhandling består av fyra fristående artiklar. Artiklarna har det gemensamt att de alla använder Bayesiansk ekonometri, i kombination med s.k. Markov chain Monte Carlo (MCMC) metoder, för att studera olika problem inom finansiell ekonomi. De första två artiklarna är ytterligare relaterade till varandra genom att de båda handlar om portföljvalsteori och skatThis PhD thesis consists of four separate papers. What these papers have in common is that Bayesian Econometrics, in combination with Markov chain Monte Carlo (MCMC) methods, is applied to study various problems in financial economics. The first two papers are further related in that they both deal with portfolio selection and estimation risk, as are the last two papers in that they both deal with
An indirect 125I-labeled protein A assay for detection of cell surface-bound rat immunoglobulins is presented. The assay is quantitative and rapid and detects as little as 1 ng of cell surface-bound Ig. It discriminates between antibodies belonging to different IgG subclasses, IgM and IgA. We describe the production and specificity control of the reagents used and show that the test can be used fo
Objective. Intraperitoneal adhesions are an important cause of postoperative intestinal obstruction, abdominal discomfort and infertility. In the present study we hypothesized that a combination of polypeptides with different surface properties, resulting in fine disperse low-soluble complexes, could be of benefit in the prevention of abdominal adhesions. Material and methods. Various polypeptides
The ultrafast carotenoid band shift upon excitation of nearby bacteriochlorophyll molecules was studied in three different light harvesting complexes from purple bacteria. The results were analyzed in terms of changes in local electric field of the carotenoids. Time dependent density functional theory calculations based on known and model structures led to good agreement with experimental results,
Background. The aim of this study was to compare laparoscopic colposuspension with tension-free vaginal tape (TVT) in terms of costs to the county. Methods. In a prospective, randomized study, we approached 270 consecutive women presenting for evaluation of stress urinary incontinence symptoms at one university hospital. Preoperatively, and at 1-year follow-up, the women underwent urodynamic eval
Dizziness and subjective balance disturbances are common complaints in cervical pain syndromes. We assessed balance function with posturography using vibration-induced and galvanically-induced body sway in consecutive patients (n = 116) with cervico-brachial pain syndrome of more than 3 months' duration. A total of 83% of the patients showed signs of cervical root compression on MRT scans. The inc
Evidence is accumulating that pituitary hormone secretion is not only regulated by feedback from hormones produced in the target organs (long feedback) on the pituitary and the hypothalamus (feedforward), but also by a feedback of the hypophyseal hormones at the hypothalamic (short feedback) and the pituitary (ultra-short feedback) level. Inhibition of thyrotropin (TSH) and MSH secretion by pituit
