1. 1. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

   Master-uppsats,

   Författare :Ali Amena Hussain; [2022-03-09]
   Nyckelord :Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

   Sammanfattning : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.

3. 2. Optimering av Savoniusturbinens effektivitet i marina strömmar med hjälp av CFD-analys av flödesriktare

   Kandidat-uppsats, Uppsala universitet/Elektricitetslära

   Författare :Leonard Hammar; Jacob Kovaleff Malmenstedt; [2022]
   Nyckelord :MCT; Marine Current Turbine; Savonius turbine; CFD; Ansys fluent; diffuser augmented turbine; Savoniusturbin; Marina strömmar; CFD; Ansys fluent; flödesriktare;

   Sammanfattning : The Savonius turbine is a self-starting vertical axis turbine that has a few advantages compared to other vertical axis turbines such as lower cost, lower noise and is relatively easy to manufacture. This turbine does however have a lower efficiency and is therefore less used in the electricity production than other turbines. LÄS MER

4. 3. Lactate as a signaling molecule : A potential role in controlling exercise induced adaptations in human skeletal muscle

   Magister-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för fysisk aktivitet och hälsa

   Författare :Fabian Nordström; [2021]
   Nyckelord :;

   Sammanfattning : Introduction The lactate molecule has a key role in human energy metabolism, particularly in skeletal muscle: acting as a buffer within the muscle cell enabling glycolysis to continue during high energy demand, as well as acting as an energy shuttle between cells. The lactate molecule has also lately been shown to act as a signaling molecule in non-human models acting as a signaling molecule regulating the transcriptional process, potentially controlling the expression of several important metabolic proteins.

5. 4. Managing Multicultural Teams in Generation Global : a case study on MobileIron

   Kandidat-uppsats, Uppsala universitet/Företagsekonomiska institutionen

   Författare :Claudia Madero; [2020]
   Nyckelord :multicultural teams; management; cultural intelligence; CQ; global identity;

   Sammanfattning : To cope with increasing demands and competition in the ever-growing global market, organizations have been increasing the use and formation of multicultural teams (MCTs). Though advantageous in numerous aspects, MCT literature lays significant focus on the struggles in managing communication and cohesion in these teams. LÄS MER

7. 5. Optimering av underhållsstrategier i åldrande kärnkraftsanläggningar : En litteratur- och intervjustudie med kompletterade fallstudie kring kabel- och rörgenomföringar

   Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Nina Back; [2020]
   Nyckelord :Sustainable maintenance strategies; Nuclear power plant; ageing; hardness measurements; resource effectiveness; reliable operations; cable- and pipe transit; Brattberg-transits; Hållbara underhållstrategier; kärnkraftsanläggning; åldring; hårdhetsmätning; resurseffektivisering; driftsäkerhet; kabel- och rörgenomföringar; Brattbergsgenomföringar;

   Sammanfattning : Rapporten baseras på en litteratur- och intervjustudie kring underhållsstrategier och komponentutbyten i kärnkraftverk, med fokus på komponenter som tenderar till att påverkas av åldring i en högre grad. Exemplifiering sker genom en kompletterande fallstudie kring kabel- och rörgenomföringar av typen Brattbergare som har packbitar bestående av ett polymert material. LÄS MER
