1. 1. mRNA-based pharmaceuticals : A literature study based on current knowledge of mRNA

   Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - Ångström

   Författare :Alicia Andersson; Isabella Åkerfeldt; Amanda Borgenstam; Ellinor Olsson; Adam Nyström; [2022]
   Nyckelord :mRNA-pharmaceuticals; mRNA therapies; mRNA vaccines; mRNA components; mRNA design; and mRNA applications.;

   Sammanfattning : This literature study provides a comprehensive overview of the current knowledge of mRNA-based pharmaceuticals, technologies and applications.  mRNA-based pharmaceuticals have newly been bought into focus as a potential brand-new drug class and many believe that it has the potential to transform areas of medicine.

3. 2. Electrical analysis of interface recombination of thin-film CIGS solar cells

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Henrik Lotse; [2020]
   Nyckelord :interface recombination; SCAPS; activation energy; temperature dependent IV; dominant recombination path;

   Sammanfattning : In this master thesis, electrical characterization of thin film CuInxGa(1−x)Se2 solar cells produced by Midsummer AB were performed with the aim of determining the dominant recombination path of these cells. Current-Voltage (IV), Quantum Effinciency (QE), temperature dependent IV (IVT) and Drive-Level Capacitance Profiling (DLCP) was used with the objective to investigate the dominant recombination path as well as provide some insight of the solar cells in order to create a baseline model using the modelling software SCAPS (Solar cell CAPacitance Simulator).

4. 3. Analyser av två VSC-HVDC-stationer genom långtidsmätningar med elkvalitetsmätare

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Martin Pettersson; [2018]
   Nyckelord :VSC-HVDC; metrology; power quality; STATCOM; voltage stability; voltage collapse; harmonics; flicker; transmission; IVT; CVT; RCVT; PQSensor; Master of Wave; inverted Rogowski coil; ELSPEC; VSC-HVDC; mätteknik; elkvalitet; STATCOM; spänningsstabilitet; spänningskollaps; övertoner; flimmer; transmission; IVT; CVT; RCVT; PQSensor; Master of Wave; inverterad Rogowskispole; ELSPEC;

   Sammanfattning : Gotland har länge präglats av mycket speciella lösningar och legat i framkant vad gäller ny teknik. Under ca 20 år har Gotland haft en VSC-HVDC-station som har stabiliserat spänningen i det gotländska nätet. HVDC Light har löst en del av de tekniska begränsningarna som hindrat utvecklingen av vindkraftverk. LÄS MER

5. 4. Influence of Na doping on tunnelling rear contact passivation in Cu(In,Ga)Se2 solar cells

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

   Författare :Markus Sköld; [2016]
   Nyckelord :Sodium; Na; CIGS; solar cells; Passivation; rear contact; Al2O3; tunnelling; tunneling;

   Sammanfattning : In this thesis Cu(In,Ga)Se2 (CIGS) solar cells with different sodiumdoping of the CIGS absorber and varying Al2O3 rear surface passivationlayer thickness have been manufactured and electrically characterised. Baseline samples and samples without passivation were used asreferences for the passivated samples. LÄS MER

7. 5. Shorter project lead times in construction

   Master-uppsats, KTH/Fastigheter och byggande

   Författare :Karin Bergstrand; Viktor Appel; [2016]
   Nyckelord :Lean Construction; Value Stream Mapping; Waste; Flow efficiency; Construction Logistics; Supply Chain Management in Construction; Scheduling; Buffers; Variability; Lean Construction; Value Stream Mapping; Waste; Flow efficiency; Construction Logistics; Supply Chain Management in Construction; Scheduling; Buffers; Variability;

   Sammanfattning : The manufacturing industry has made an extensive journey through the last century when it comes to increasing productivity. Results in the construction industry end up far behind manufacturing and do not show anywhere near the same efficiency increase, improved quality or decreased costs. LÄS MER
