A prospective randomised study was made of 20 patients who underwent acromioplasty for the chronic impingement syndrome. Ten were operated on by Neer's technique and 10 with a modification where the deltoid origin was spared. Rehabilitation was more rapid with a better range of movement in the latter group. Acromioplasty with this modification offers benefits compared with the standard procedure.

Nine children with congenital bladder exstrophy treated without pelvic osteotomy were analyzed clinically and radiologically at a mean age of 13 years (range 9-16 years). The acetabular and femoral version angles were measured by computed tomography (CT) imaging. Two of the children had a slight waddling gait, but none of them had any pain and they could participate in sports without problems. The

The regulation of acetylcholine (ACh) release from cholinergic neurons transplanted to the hippocampus or neocortex was studied by microdialysis in awake rats. Fetal basal forebrain tissue was implanted as a cell suspension or solid graft into the fimbria-fornix-lesioned hippocampus, or as a cell suspension into the frontal cortex after excitotoxic lesion of the nucleus basalis. Several months aft

This paper presents an angular-domain massive MIMO detector which exploits sparsity in massive MIMO channel along with a reconfigurable systolic array architecture to achieve high area efficiency. The underlying idea is to perform signal detection in the angular domain, where the channel matrix can have much lower dimension due the limited number of dominant angles (of arrival and departure) of th

Aim: This population-based study assessed the incidence of rickets in infants up to age of one born in Sweden from 1997 to 2014. We also examined maternal and perinatal factors and co-morbidity. Methods: We used Swedish National Board of Health and Welfare registers and data from Statistics Sweden. The outcome measure was an International Classification of Diseases, Tenth Revision, code for ricket

Att begränsa den globala uppvärmningen till under två grader - tvågradersmålet - är ett övergripande mål i klimatpolitiken såväl internationellt som i Sverige. Tvågradersmålet kan ses som ambitiöst jämfört med globala trender idag, men den utesluter inte alla klimateffekter. Om målet är tillräckligt beror alltså även på vilka risker vi kan acceptera och vad vi kan åtgärda med anpassning. För att k

Nonlinear phenomena have been reported in many diverse disciplines, including physics, health sciences, engineering, literature, neurology, geology and music. As this paper will show, nonlinear phenomena have robust potential for both performance and composition. It has been shown that nonlinear phenomena occur in the sound production of extra-normal extended techniques for both voices and musical

The purpose of this article is to empirically investigate the present state of the performance measurement systems (PMS) at 7 sites of 6 different large Swedish manufacturing companies. The methodology has both a bottom-up and a top-down perspective. Important findings are that the PMSs are very similar in how they function but differ a lot in what is measured.
