1. 1. High-grade spondylolisthesis in young patients : Long-term results of in situ fusion

   Författare :Anders Joelson; Per Wretenberg; Karin Frennered; Hans Tropp; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adjacent segment disk degeneration; Fusion in situ; Health-related quality of life; Sagittal balance; Self-image; Spondylolisthesis;

   Sammanfattning : The purpose of this long-term follow-up of 38 of 40 consecutive patients was to evaluate the results of uninstrumented in situ fusion for high-grade isthmic spondylolisthesis three decades after surgery. The mean age at surgery was 14 (range 9-24) years. LÄS MER

3. 2. Endoplasmic Reticulum Dynamic Structural Changes in Neurons: The Fission-Fusion Phenomena

   Författare :Krzysztof Kucharz; Sektion IV; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fragmentation; fission; endoplasmic reticulum; neurons; FRAP; primary cultures; organotypic slice cultures; in vivo; in situ; calcium; fusion; NMDA receptor; 2-photon microscopy; confocal microscopy;

   Sammanfattning : The endoplasmic reticulum (ER) is crucial for protein synthesis and protein maturation, is involved in cell stress and serves in neurons as the major intracellular Ca2+ store. Neuronal ER forms a continuous network of cisterns and tubules extending from soma to a subset of dendritic spines. LÄS MER

4. 3. In-situ monitoring of laser powder bed fusion applied to defect detection

   Författare :Claudia de Andrade Schwerz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; defect detection; productivity; nickel-based superalloy; process monitoring; pores; powder bed fusion; spatter; defect mitigation; mechanical properties; lack of fusion; melt pool; Additive manufacturing;

   Sammanfattning : Additive manufacturing technologies, particularly laser powder bed fusion (LPBF), have received much attention recently due to their numerous advantages over conventional manufacturing methods. However, the use of LPBF is still quite restricted, mainly due to two factors: its typically low productivity, which makes the technology less competitive in applications with moderate to high production volumes, and its limited reliability, particularly relevant for applications where high performance is required from the materials.

5. 4. Expression and Mutation Analyses of Candidate Cancer Genes In Situ

   Författare :Sara Kiflemariam; Tobias Sjöblom; Fredrik Pontén; Mef Nilbert; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; in situ; in situ hybridization; padlock probes; mRNA; tyrosine kinases; tyrosine phosphatases; fusion transcripts;

   Sammanfattning : Cancers display heterogeneity in genetic profiles of the individual cancer cells and in the composition of different malignant and non-malignant cell populations. Such intra-tumor heterogeneity plays a role in treatment response and the emergence of resistance to cancer therapies. LÄS MER

7. 5. Spectral analysis in laser powder bed fusion

   Författare :Benedikt Brandau; Frank Brückner; Alexander Kaplan; Dan Roth-Fagaraseanu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectral monitoring; Laser powder bed fusion; Laser optics; Absorbance; Produktionsutveckling; Manufacturing Systems Engineering;

   Sammanfattning : This thesis is about the investigation of the spectral interaction of electromagnetic radiation with metal powders. For this purpose, spectral data of powders for laser powder bed fusion processes are investigated in three papers using different techniques. LÄS MER
