2. 1. Optical Analysis and Characterisation of the Climate Research Instrument STEAMR

   Author : Arvid Hammar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limb viewing; Monte Carlo; Stratosphere-Troposphere Exchange And climate Monitor Radiometer STEAMR ; quasi optics; THz; antennas; multi-beam; tolerance analysis; submillimeter-wave instruments; radiometers;

   Abstract : A growing interest for making high resolution observations in the upper troposphere and lower stratosphere has motivated the development of the multi-beam satellite-borne instrument Stratosphere-Troposphere Exchange And climate Monitor Radiometer (STEAMR). The measurements made by STEAMR will be used to monitor trace-gases and link the occurence of these to the Earth's climate by accurate modeling of the atmosphere. READ MORE

4. 2. Process planning for precision manufacturing : An approach based on methodological studies

   Author : Mats Bagge; Bengt Lindberg; Anders Kinnander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; precision manufacturing; machining; tolerance chain analysis; process behaviour; process performance; process capability; in-process workpiece.; Production Engineering; Industriell produktion;

   Abstract : Process planning is a task comprising a broad range of activities to design and develop an appropriate manufacturing process for producing a part. Interpretation of the part design, selection of manufacturing processes, definition of operations, operation sequences, machining datums, geometrical dimensions and tolerances are some common activities associated with the task.

5. 3. PCR inhibition mechanisms in forensic DNA analysis

   Author : Maja Sidstedt; Teknisk mikrobiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCR inhibition mechanisms; Real-time PCR; Digital PCR; Massively parallel sequencing;

   Abstract : In forensic DNA analysis, the polymerase chain reaction (PCR) enables DNAanalysis of minute biological crime scene traces. PCR is an enzymatic reaction for amplification of specific DNA fragments involving both biochemical andbiophysical processes. The main analytical challenge is posed by the nature of the samples of interest. READ MORE

6. 4. Role of cholesterol metabolism in hepatic steatosis and glucose tolerance

   Author : Osman Salih Osman Ahmed; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The liver is the central organ for lipid, lipoprotein and glucose homeostasis, thus hepatic metabolic disturbances can predispose individuals to develop cardiometabolic disorders (CMD) such as atherosclerotic cardiovascular diseases (ASCVD), type 2 diabetes mellitus (T2DM), and nonalcoholic fatty liver disease (NAFLD).The overall aim of this thesis was to expand the knowledge on how genetic and pharmacological interventions on hepatic and intestinal cholesterol metabolism could affect the pathophysiology of CMD.

7. 5. The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity

   Author : Niklas Gustavsson; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; oxidative stress; thermostability; temperature stress; stress tolerance; sHsp; protein aggregation; molecular chaperone; Heat stress; methionine sulfoxidation; Biokemi; metabolism; Plant biochemistry; Växtbiokemi;

   Abstract : The chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. READ MORE
