Objectives: The aim of this study was to review the presentation and analysis of ordinal data in three international nursing journals in 2003. Method: In total, 166 full-length articles from the 2003 editions of Cancer Nursing, Scandinavian Journal of Caring Sciences and Nursing Research were reviewed for their use of ordinal data. Results: This review showed that ordinal scales were used in abo
The era when customers bought what companies produced is long gone. The situation is now reversed and companies must produce what customers want; while the customers' preferences are, furthermore, becoming increasingly diverse. This has forced companies to adopt a new mode of thinking in order to survive. The strategy, by necessity, has become to manufacture flexibly. This thesis focuses on stra
The solvations of positively and negatively charged model ions in water droplets have been studied using Monte Carlo simulations performed with a polarizable intermolecular potential function model. Special focus has been placed on the position of the ion in the water droplet. It was found that the sign of the ionic charge is of minor importance but an increased ionic charge localizes the ion to t
We conjecture that the fractal dimension of hyperbolic sets can be computed by adding those of their stable and unstable slices. This would facilitate substantial progress in the calculation or estimation of these dimensions, which are related in deep ways to dynamical properties. We prove the conjecture in a model case of Smale solenoids.
Den amerikanska staden Phoenix ligger omgiven av berg i Sun Valley, Arizona. Klimatet är varmt och glest utspridda kaktusar står som eldgafflar mot skyn. Tänk på en typisk Vilda Västern-film så får du en förnimmelse av vad som kännetecknar Phoenix omgivningar. Trots ökenlika förhållanden bor där idag 1,3 miljoner invånare. Befolkningstillväxten tog fart på allvar luftkonditioneringen introducerade
In an earlier paper we reported on a new septum magnet design with a magnetic flux filter [1]. Now the first septum magnet is in operation as in injection septum magnet for the MAX I storage ring. We dcscribe the actual mechanical construction and the field measurements of the new magnets. The fine Structure of the septum nose needed several trials in the construction until we found the final solu
In normal conscious rats investigated by continuous cystometry, intravesically instilled prostaglandin (PG) E2 facilitated micturition and increased basal intravesical pressure. The effect was attenuated by both the NK1 receptor selective antagonist RP 67,580 and the NK2 receptor selective antagonist SR 48,968, given intra-arterially, suggesting that it was mediated by stimulation of both NK1 and
Three enantiomeric pairs of Diels-Alder adducts of 2,5-diphenylphosphole-1-oxide have been resolved by elution of each of the enantiomers with 95% ethanol from a swollen microcrystalline triacetylcellulose stationary phase. The degree of separation achieved in each case was confirmed by comparing the absorbance maximum of the UV spectrum of each separated enantiomer with that of a similar concentr
The pneumococcus is the principle cause of bacterial pneumonia and also a major cause of bacterial meningitis. The mechanisms and sites of pneumococcal adherence and invasion of the respiratory tract in vivo are not clear however. We have made pneumococci expressing green fluorescent protein (GFP) and used it to trace pneumococcal adherence and invasion in vivo. By using GFP pneumococci we have sh
Popular AbstractSveriges första stora kärnkraftsreaktor togs i bruk 1972. Samma år kom kärnkraften att för första gången på allvar ifrågasättas i den svenska riksdagen. Under loppet av ett par år förvandlades kärnkraftsfrågan till den nutida svenska politikens kanske mest kontroversiella och omdebatterade fråga. I denna avhandling analyseras den riksdagspolitiska debatten om kärnkraften mellan åreThis study applies a qualitative discourse theoretical method to analyse the central argumentation in the parliamentary debate on nuclear power in Sweden during 19721980, reconstructed from official documents such as governmental and parliamentary bills, committee reports, parliamentary debate protocols, and official commission reports. Particular concern is directed to the process in which vari
Today, as a rule, the most cost-effective way to remove nitrogen from municipal wastewater is the biological method based on nitrification and subsequent denitrification. All biological systems may be affected by toxicants, and biological nitrogen removal is no exception. An investigation of influent wastewaters from 109 Swedish municipal wastewater treatment plants was accomplished. Inhibitory s
The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. However, in lean combustion, problems related to the flame stability can arise. Swi
