36. Experimental Verification of BP-HiPIMS Thrusters
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The ion acceleration process in Bipolar High Power Impulse Magnetron Sputteringis investigated for use in a novel space propulsion system - the BP-HiPIMS thruster.The interest for BP-HiPIMS has recently been growing within the area of thin filmdeposition due to the theorised acceleration of target ions caused by the reversedpulse following the regular HiPIMS pulse.

37. Modeling of the pedestal performance in the DTT tokamak
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysikSammanfattning : This master thesis concerns the modeling of the pedestal in the fusion plasma device DTT and its dependence on several plasma parameters. The modeling was performed using the Europed code which is based on the EPED model. Several parameters were found to have a significant impact on the pedestal predictions. LÄS MER
38. Analysis of Hall effect thrusters using Hybrid PIC simulations and coupling to EP plume
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : In the last 30 years, numerical models have been developed to properly analyze Hall eect thrusters (HET),leading to a bridge between analytical prediction/empirical intuition and experiments. For companies in thespace sector, these codes serve to much more than simply simulating the thruster, but it provides a fast, cheapand reliable tool for processes such as validation and verication procedures, as well as for technical developmentof the thruster.

39. Evaluation of Manual and QIAcube miRNA Extraction from Plasma with the miRNeasy Advanced Kit from Qiagen
Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Sepsis is a syndrome causing millions of deaths every year. The diagnosis today uses several parameters one of which is blood culture. It can take up to 48 hours to get results. Sepsis can lead to major organ dysfunction in a span of four hours; therefore time is of the essence. LÄS MER
40. Field study of the drought’s impact on feeding strategy and biological parameters in early lactation dairy cattle
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : The summer of 2018 was unusually warm and dry. For animal production, this resulted in poor pastures, reduced harvests of crops, such as roughage and grains, and increased risk for heat stress in the animals. The drought led to problems as in shortage of animal feed, which made the feeding of dairy cattle difficult. LÄS MER
