Silicone tubes of appropriate sizes were used to enclose the injured zone of transsected ulnar and median nerves in the human forearm as an alternative to conventional microsurgical repair of the nerve trunk. A gap measuring 3-5 mm was left intentionally between the nerve ends inside the tube. The clinical early results from a prospective randomised study that compared these two principles have re

Since many years, life charting has been used to describe the life course and life events of psychiatric patients. The aim of the present study was to describe and evaluate time geographic life. charts of 11 former psychiatric patients in order to promote systematic descriptions of their life events over time. Information on all events which was gathered from the life charts was analysed by manife

Pseudoneurological symptoms (i.e., conversion disorder), historically subsumed within the "hysteria" concept alongside phenomena such as psychogenic amnesia and multiple personality disorder have been classified as somatoform disorders since DSM-III. Since then, there have been repeated calls to reclassify conversion disorder with the dissociative disorders, as in ICD-10. The authors review issues

Popular Abstract in Swedish Allt fler marknads- och teknikdrivna programvarutvecklingsföretag ställs inför utmaningen att hantera tusentals krav som uttrycks i vanlig textuell form. Det stora antalet krav orsakar flaskhalsar i kravhanteringsprocessen vilket påkallar en mer effektiv kravhantering. Denna avhandling presenterar resultaten från empiriska undersökningar av att använda språkvetenskapliAn increasing number of market- and technology-driven software development companies face the challenge of managing several thousands of requirements written in natural language. The large number of requirements causes bottlenecks in the requirements management process and calls for increased efficiency in requirements engineering. This thesis presents results from empirical investigations of usi

The "European Guidelines on Quality Criteria for Diagnostic Radiographic Images" do not address the choice of the film characteristic (H&D) curve, which is an important parameter for the description of a radiographic screen–film system. The image contrast of clinical lumbar spine and chest radiographs was altered by digital image processing techniques, simulating images with different H&D

The titration properties of a fatty acid solubilized in different types of micelles, cationic, anionic and nonionic, have been investigated experimentally and theoretically. The solution containing micelles, counterions, and added salt was treated as a dielectric continuum in the Monte Carlo simulations. The dielectric permittivity of the interior of the micelle can have a profound effect on the c

We present a case of hematogenous dissemination of transitional cell carcinoma in the bladder to the prostate in a 36-year-old male in whom cystoprostatectomy was performed and an orthotopic bladder substitute constructed.

We conducted large-scale, systematic sampling of influenza type A virus in migratory waterfowl (mostly mallards [Anas platyrhynchos]) at Ottenby Bird Observatory, southeast Sweden. As with previous studies, we found a higher prevalence in fall than spring, and among juveniles compared with adults. However, in contrast to other studies, we found that prevalence in spring was sometimes high (mean 4.

A simple, novel, and general method is presented in this paper for approximating the sum of independent or arbitrarily correlated lognormal random variables (RV) by a single lognormal RV. The method is also shown to be applicable for approximating the sum of lognormal-Rice and Suzuki RVs by a single lognormal RV. A sum consisting of a mixture of the above distributions can also be easily handled.

Efficient use of industrial robots requires a strong interplay between user level commands, the motion control system, and external equipment. It should also be possible for an experienced application engineer to tailor the motion control to a specific application in a convenient way, instead of deficient utilization of the device or tricky user programming which is often the case today. A layered

Elevated solar UV-B radiation associated with stratospheric ozone reduction may exert effects on terrestrial ecosystems through actions on plants, microbes, and perhaps on some animals. At the ecosystem level, the effects are less well understood than at the molecular and organismal levels. Many of the most important, yet less predictable, consequences will be indirect effects of elevated UV-B act

This paper presents a novel approach to the modeling of failure of finger-joints in glued-laminated beams. A nonlinear strain-softening model with stochastic material parameters was used to characterize the failure zone of the finger-joint. Monte Carlo simulations of the behavior of finger-joint laminations and of laminated beams were performed using the finite-element method. Various lamination t

In the new sub-micron beamline at the Lund Nuclear Microprobe facility a special large area HPGe X-ray detector has been installed. It consists of eight 100-mm(2)-size detector elements arranged in an annular formation around the beam entrance hole. Different parameters like FWHM, FWTM, peak-to-background ratio and peak-to-valley ratio for each individual detector element as well as their sum spec

Genotyping of hepatitis C virus (HCV) is important because of its clinical and epidemiological implications. We report here the distribution of HCV genotypes in various patient groups in Finland using a rapid and reliable HCV typing method based on restriction fragment length polymorphism (RFLP) of the amplified DNA from the 5' non-coding region of the genome. The reaction product from the primary
