The process K-l3 is calculated to two-loop order (p(6)) in chiral perturbation theory (ChPT) in the isospin conserved case. We present expressions suitable for use with previous work in two-loop ChPT where the order p(4) parameters (L-i(r)) were determined from experiment. We point out that all the order p(6) parameters (C-i(r)) that appear in the value of f(+)(0) relevant for the determination of
Persistent aneurysm perfusion represents failure of endovascular repair. The leak may occur around either end of the prosthesis or through a collateral route. Most cases can be treated by endovascular means. Stents can be rotated, the prosthesis can be lengthened at either end, and collateral pathways can be occluded, all without recourse to open repair. This report describes the management of per
This paper presents an investigation of CO formation in a lean premixed propane/air turbulent flame in an afterburner configuration. A previous experiment showed that a high amount of CO was formed in the mean turbulent flame brush. To explain the high CO concentration in the flame zone, the effects of flame stretch and flame wrinkling are studied, based on an ensemble averaged laminar flamelet li
This study describes the chydorid (Branchiopoda, Anomopoda) assemblages from 66 European shallow lakes, and presents data relating the assemblages to lake type and ecological quality. Forty species, out of a total recorded European fauna of 60 species, were found in the study sites. No significant differences were found between chydorid assemblages associated with rock and plant substrata. Pattern
Popular Abstract in Swedish Tvärsektoriella nätverk mellan myndigheter, näringsliv och olika intressegrupper har tilldelats en allt större betydelse, då det varit en vanlig uppfattning att en hållbar utveckling bäst skapas genom ett gemensamt ansvar. Uppfattningarna om resultaten av dessa initiativ uppvisar dock spektakulära skillnader: från att framstå som oslagbara lösningar på de utmaningar soThe importance of cross-sectoral collaborative initiatives, that is partnerships of governments, civil society and the private sector, was elevated due to the belief that the issues of SD are a collective responsibility of all societal actors. The assessment of these initiatives is ranging dramatically; from giving them a status of an unbeatable solution for the SD challenges, to blaming them for
The report contains abstracts of master theses (examensarbete) made at the department of Automatic Control, Lund, during the academic year 1979/80. During this year 12 theses were made by 15 students. The theses are written in Swedish with an English abstract.
Conjugated polymers are becoming interesting materials for a range of optoelectronic applications. However, their often complex electronic and structural properties prevent establishment of straightforward property-function relationships. In this paper, we summarize recent results on the photophysics and excited state dynamics of conjugated polymers, in order to paint a picture of exciton formatio
Objective: To assess overall resource consumption, work capacity and quality of life of patients with multiple sclerosis in nine European countries. Methods: Information on resource consumption related to multiple sclerosis, informal care by relatives, productivity losses and overall quality of life (utility) was collected with a standardised pre-tested questionnaire from 13186 patients enrolled i
Treatment of a benzene solution of (tmeda)PdMe2 or (dppe)PdMe2 with carbon dioxide gives the corresponding methyl bicarbonate complex, (L-L)PdMe(O2COH). These were characterised by NMR spectroscopy and elemental analysis. Under strictly dry conditions no reaction was observed. Recrystallisation of the tmeda bicarbonate complex from acetone yields the corresponding eta(2)-carbonate complex, which w
Purpose: alpha-Melanocyte stimulating hormone (alpha-MSH; Fluka Chemie AG, Geneva, Switzerland) and oxytocin induce erection in rats after intracerebroventricular administration. We studied possible interactions of alpha-melanocyte stimulating hormone with mechanisms pertaining to oxytocin or nitric oxide. Materials and Methods: We used 78 anesthetized male Sprague-Dawley rats. Catheters were impl
The gleno-humeral joint space in standard antero-posterior images of 175 normal subjects was measured at three different sites. The average of the three measurements, the integral joint space, was calculated and was found to be between 4 and 5 mm. The value does not change with age, except in women, in whom it increases slightly. A narrow joint space in an elderly patient should not be expected si
For the new Munich high-flux reactor FRM-II a fission fragment accelerator is under design. The accelerator will deliver intense mass-separated beams of very neutron-rich fission fragments with energies at and beyond the Coulomb barrier. One main physics goal will be the investigation of very heavy neutron-rich nuclei produced in fusion reactions.
In order to elucidate the influence of nicotine smoking on bone mass in elderly women, bone mass was cross-sectionally assessed by dual energy X-ray absorptiometry (DXA) in total body, hip and lumbar spine, as well as with ultrasound of calcaneus and phalanges of the hand. Subjects were 1,042, 75-year old women, recruited on a population basis (Osteoporosis Prospective Risk Assessment (OPRA) study
Along with an increasingly globalized business environment and a strongly held corporate belief that the world can be rationally managed, the last two decades have witnessed a growing demand for normative models dealing with cross-cultural management issues. This trend has allowed cross-cultural management to establish itself as a significant research field, with much of the initial inspiration co
beta-Microseminoprotein (MSP) is a small cysteine-rich protein (molecular mass about 10 kDa) first isolated from human seminal plasma and later identified in several other organisms. The function of MSP is not known, but a recent study has shown MSP to bind CRISP-3, a protein present in neutrophilic granulocytes. The amino acid sequence is highly variable between species raising the question of th
Den icke-fiktiva svenska naturskildringen har så gott som uteslutande förknippats med manliga namn. I den här undersökande essän vill jag vidga fältet genom att presentera ett antal kvinnliga skribenter och deras olika förhållande till naturen: Esther och Ruth Kolthoff, Karin Jansson, Elsa af Trolle, Harriet Hjorth, Margit Geijer, Margaret von Bismarck, Margareta Ekström, Ingegerd Möller.
Projectilelike fragment emission is studied via two-particle correlation functions, constructed from coincidence data detected at very forward angles (0.7degreesless than or equal totheta(lab)less than or equal to7degrees) in the E/A=44 and 77 MeV Ar-40+Al-27 reactions. The shape of the proton-proton correlation function is unexpected. Possible origins of this effect are discussed and a way to ree
