Weekly resource use data for local wound treatment was collected from a clinical survey (138 patients). Annual costs were calculated from the weekly resource usage multiplied by unit costs and published epidemiological prevalence data for Sweden. The average weekly cost was 101 euro, though it differed depending by ulcer size. The total direct annual cost of venous leg ulcers in Sweden could be es

Objectives: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. Methods: Data were collected in four laboratories with a total of 20 males and 20 females perfo

Excited states in the T-z-1/2 nucleus Rb-75 were observed for the first time using the Ca-40(Ca-40,alpha p) reaction at 128 MeV. Identification was achieved using events detected by the Daresbury recoil separator in coincidence with gamma rays detected in the 45 element EUROGAM I Ge-detector array. Threefold events were used to build a decay scheme which consists of two rotational bands observed t

Driving pattern, i.e. the speed profiles of vehicles, was studied in connection with variables in the driver-car-environment system. Data were collected using five measuring cars that were driven by 29 randomly chosen families for two weeks each. The cars were equipped with data-logging devices that enabled studies of the speed and acceleration patterns of the vehicles as well as engine speed and

We detect a significant angle-dependence in the core level and valence line shapes of photoelectron spectra of single crystal K3C60. This allows the identification of bulk and surface components in the data, and allows us to explain the anomalous line shapes observed for this system. The states near the Fermi level are associated with the bulk of the sample. There is strong evidence of an insulati

Popular Abstract in Swedish Denna studie rapporterar ett undervisningsförsök i en 8:e klass (age 14-15) med 20 elever. Eleverna har bearbetat en naturvetenskaplig problemställning om växthuseffekten och jordens globala uppvärmning utifrån ett problemlösande och informationssökandarbete i grupp. Deras uppgift har varit att beskriva de fenomen och faktorer som påverkar jordens globala temperatur i oThis study gives an account of a teaching situation in the eighth grade with 20 student's aged 14-15. The students have worked with a scientific problem focussed on the greenhouse effect and the earth's global warming, based on a problem solving and information seeking way of working in groups. Their task has been to describe the phenomena and factors that influence the earth's global temperature

I denna rapport beskrivs några av de mekanismer som kan leda till sprickbildning. Rapporten behandlar enbart de fuktrelaterade mekanismerna. Samma mekanismer kan även relateras till temperaturrörelser. Det som förorsakar sprickor är förhindrade rörelser hos putsen.

Sediment-dispersed extraterrestrial chromite grains (63-355 mu m) have been recovered in a section across the Arenig-Llanvirn transition in the Killerod quarry in southeastern Scania. Previous studies of the same stratigraphic interval in the Orthoceratite Limestone at Kinnekulle, ca. 350 km to the north in Vastergotland, have shown a two orders of magnitude increase in extraterrestrial chromite b

Popular Abstract in Swedish Idag lagras allt fler kartor digitalt och nya metoder krävs för att förbättra denna digitala hantering. Ett område som studerats under senare tid är automatiska metoder för kartografisk generalisering. Kartografisk generalisering innebär att man förenklar informationen i en karta för att göra den mer lättläst i den önskade skalan. Denna avhandling beskriver en optimerinCartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. Two topics are treated: optimisation methods in graphic generalisation, and propagation of updates between cartographi

The DTMROC-S is a 16-channeI front-end chip developed for the signal processing of the ATLAS straw tube detector, TRT. Due to a highly radioactive environment, the chip is fabricated in a commercial 0.25μm CMOS technology hardened by layout techniques and, in addition, a special methodology was used to improve the circuit's robustness against Single Events Effects (SEE) caused by ionizing particle

Pharmacy-grade exogenous lung surfactant preparations of bovine and porcine origin, dispersed in physiological electrolyte solution have been studied. The organization and dynamics at the air/water interface at physiological temperature was analysed by neutron reflection. The results show that a well-defined surface phase is formed, consisting of a multilayer structure of lipid/protein bilayers al
