11. Ser inte skogen för alla träd : Reducering av kvalitetsbristkostnader enligt förbättringscykeln DMAIC. En fallstudie vid Derome Timber AB
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : Den svenska skogsindustrin är den tredje största exportören av skogsprodukter i världen och närmare 80% av produktionen exporteras. Den höga efterfrågan på svenska skogsprodukter har tillåtit det svenska sågverksföretaget Derome Timber AB att göra nyinvesteringar som resulterat i ökad produktion. LÄS MER
12. Control charts for statistical quality control of Swedish stroke care using Riksstroke data
Kandidat-uppsats, Umeå universitet/StatistikSammanfattning : The aim of this study was to implement statistical quality control to stroke care in Sweden by designing control charts for data from the Riksstroke registry to detect potential unnatural, or special cause variation in the years 2019-2020. Suitable control charts were designed for three quality indicators: the time elapsed from hospital admission to receiving reperfusion therapy (door-to-needle time), the proportion of patients directly admitted to stroke unit, and the fatality rate.

13. Improving Availability of the Pelletization Process
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. LÄS MER
14. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for NanoscienceSammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

15. QC upgrade and verification for HS-Lenti RT Activity Kit
Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The aim of this project was to present a cost-efficient quality control routine to ensure thefunctionality of HS-Lenti RT Activity Kit, an ELISA-based kit produced by Cavidi AB, thatscreens for lentiviruses such as HIV. Two main methods for quality control are presented inthis report; acceptance sampling and Statistical Process Control (SPC). LÄS MER
