This thesis measures cost efficiency in the production of health care and social services in Sweden. The object of analysis is not provider efficiency, but instead the relative efficiency of political organizations or different contractual arrangements. The thesis focuses on: 1) the measurement of cost efficiency, 2) the investigation of potential trade-offs between quantity of health care service
The plan for the final disposal of spent fuel front Swedish nuclear power plants is to place it in copper canisters that are sealed and stored in a deep repository. The canisters will be sealed by friction stir welding (FSW) and the reliability of this process has now been evaluated. The reliability study was performed in three steps: first an optimization experiment to identify optimal process se
Transient evoked otoacoustic emissions (TEOAEs) have been analyzed for objective assessment of hearing function and monitoring of the influence of noise exposure and ototoxic drugs. This paper presents a novel application of the Hilbert-Huang transform (HHT) for detection and time-frequency mapping of TEOAEs. Since the HHT does not distinguish between signal and noise, it is combined with ensemble
Software inspection is a method to detect faults in the early phases of the software life cycle. In order to estimate the number of faults not found, capture-recapture was introduced for software inspections in 1992 to estimate remaining faults after an inspection. Since then, several papers have been written in the area, concerning the basic theory, evaluation of models and application of the met
A stirred tank membrane reactor is used to study the kinetics of polygalacturonic acid (PGA) enzymatic hydrolysis. The reactor operates in semicontinuous configuration: the native biopolymer is loaded at the initial time and the system is continuously fed with the buffer. The effect of retention time (from 10 1 to 142 min) and membrane molecular weight cutoff (from I to 30 kDa) on the rate of perm
It can be difficult to engage colleagues with the findings and recommendations of an externally-funded project, even when, or perhaps particularly when, it has major implications for institutional processes. The authors were involved with a large single-institution Higher Education change project that aimed to make the university more responsive to changes in curriculum needs, the student voice, e
In this article we report on how 64 dentists working in a big city in southern Sweden view their profession. The dentists ranged in age from 30 to 70 years (as it was indicated in intervals of 10 years). Their professional experience ranged from 2 to 44 years (mean, 23 years). We collected their views on the ideal skills of a good dentist by means of a questionnaire. From this material we identifi
Hepatitis B virus (HBV) infection remains a major public health threat in the Middle East and North Africa (MENA). Phylogenetic analysis of HBV can be helpful to study the putative transmission links and patterns of inter-country spread of the virus. The objectives of the current study were to analyze the HBV genotype/sub-genotype (SGT) distribution, reverse transcriptase (RT), and surface (S) gen
We investigate self-heating in vertical, gate-all-around III-V InAs/InGaAs nanowire MOSFETs using pulsed IV measurements at various temperatures. Low temperature measurements reveal a negative output conductance indicating self-heating in the transistor. Under pulsed measurements, an increase in drain current (15%) and transconductance (30%) are observed at room temperature, with values influenced
Currently well established technology-based manufacturing companies with a service business provides their markets with innovative and reliable products. Despite this, these companies often find their service delivery process to be inefficient, due to its time-based nature. Furthermore, the markets on which they operate are currently experiencing a shortage of qualified service personnel and thus
Småskalig plattform för upprening av monoklonala antikroppar Utvecklingen av en uppreningsplatform för antikroppar visar en 30% ökning i produk-tivitet med hjälp av parallella flödesbanor. Det är nu också möjligt att upprena ännu fler prov per körning än tidigare. Utvecklingen av nya antikroppar blir allt mer viktigare i dagens samhälle för att kunna förbättra vår analytiska och diagnostiska föThe aim of this project is to transfer and implement a monoclonal antibody purification process that is traditionally done on an ÄKTAxpress to another machine called the ÄKTA pure. This is due to the fact that the ÄKTAxpress is being discontinued by the manufacturer and a replace-ment machine is needed for the time being. The project will include developing some new meth-ods that might also highli
En ny början för Skånes rikkärr Ibland när du går ute på den skånska myllan en dag i juni kan du träffa på ett sankt område med påtagligt mosstäcke och vackra orkidéer; då har du vandrat in i ett rikkärr och med tanke på orkidéerna så rör det sig med största sannolikhet om ett extremrikkärr. Vad är då ett rikkärr och varför behöver vi börja arbeta hårt med att bevara denna något gäckande naturtypRich fens contribute with numerous ecosystem services, such as the highest biodiversity found among wetlands, water purification, carbon sequestration, hydrological services, recreational and educational services are all part of services provided from rich fens. Drainage and land-use change has severely damaged or destroyed these services in many regions of Europe and Sweden; restoration plans are
This thesis examines the diachronic semantic development in terms of metonymization and metaphorization for 30 nouns loaned into the Swedish language between the 13th and 20th centuries from a cognitive-semantic point of view. Through the framework of Lexical Meaning as Ontologies and Construals (LOC) combined with a study of the occurrence of metaphorization, metonymization, widening and narrowin
Fossila bränslen är mycket viktiga för dagens samhälle och transportsektorn är nästan helt beroende av dem. Tyvärr påverkar de miljön negativt och bidrar till att växthusgasnivå ökar. Jordens medeltemperatur har ökat med 0.8°C sedan början av industrialiseringen. Den globala uppvärmningen är ett naturligt förlopp, men har under de senaste åren varit en stor del av människors bidrag. Idag har atmosOil is very important for today’s society and the transportation sector is almost completely dependent on this material. Unfortunately, it affects the level of greenhouse gases negatively which in turn contribute to global warming. Therefore, it is necessary to reduce greenhouse gas emissions, especially in the sectors that emit the most, as transportation sector. The European Parliament has decid
Den 1 januari 2016 skärptes kraven för luftutsläpp från förbränningsanläggningar genom För-ordningen (2013:252) om stora förbränningsanläggningar. I förordningen skärptes bland annat kraven för utsläpp av kväveoxider, NOX. Till följd av de skärpta kraven berördes Kraftringens produktionsanläggning Gunnesboverket. På anläggningen finns tre biooljeeldade hetvatten-pannor för fjärrvärmeproduktion därNew regulations regarding emissions of air pollutants came into force as of January 1st 2016 in Sweden. The regulations are found in “The Regulation on Large Combustion Plants” SFS 2013:252. The regulation contained stricter regulations of NOX emissions which affected the energy company Kraftringen and their three biooil-fueled boilers, at the heating plant Gunnesboverket, that are used for produc
Two different techniques exist for glass fiber production, direct melt bushing and marble bushing. The purpose of the project was to study the glass fiber production process and investigate the possibilty of constructing mathematical models from experimental data. This part also included implementation of a DAQ system to obtain the expeimental data. A second objective was to construct an efficent
