  1. 1. The impact of criminal and externalizing behaviors on aging : Long-term associations with health and dementia

    Författare :Carmen Solares Canal; Henrik Larsson; Jonas Persson; Henrik Andershed; Björn Hofvander; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Older adults; aging; criminal behavior; externalizing behaviors; violent crime; dementia; Alzheimer s diseases; mental health; physical health; epidemiology;

    Sammanfattning : Previous studies have shown that criminal and other externalizing behaviors are associated with several adverse outcomes, but very little is known about the impact of these behaviors beyond middle adulthood. Few studies have explored how a life-course background of criminal and externalizing behaviors influence aging and more specifically, whether it is associated with the onset and development of different neurodegenerative, mental, and physical health disorders when aging.

  3. 2. Nanowires in Cell Biology

    Författare :Henrik Persson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phase holographic microscopy; Nanowires; living cells; cell injection; Fysicumarkivet A:2014:Persson;

    Sammanfattning : This thesis explores the interactions between cells and nanowires, to increase our understanding of how cells are affected and how they can be manipulated by these one-dimensional, semiconductor crystals (lengths 1-10 µm, diameters .... LÄS MER

  4. 3. Estimation of forest parameters using 3D satellite data : stereogrammetry, radargrammetry and interferometry

    Författare :Henrik Persson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Accurate data about the forest are needed both in climate research and forest management planning. This thesis focuses on using different types of three-dimensional (3D) satellite data sources to accurately estimate forest variables, primarily above-ground biomass (AGB) and tree height (H).

  5. 4. Inter-System Handovers in Heterogeneous Wireless Systems

    Författare :Henrik Persson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hierarchical structure; performance analysis; inter-system handover; wireless systems; handover terminology;

    Sammanfattning : To better utilize existing wireless systems, they can be combined together to interact and thereby provide better balanced capacity. They can further profit from this by getting their ongoing connection moved from the current system to another. The main issues are to make this move without losing the ongoing connection and to make it seamless, i.e. LÄS MER

  7. 5. A Model System for Powder Injection Moulding – Physical Properties and Mould Filling Analysis

    Författare :Henrik Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; processing conditions; thermal properties; computer simulations; rheology; powder injection moulding; mould filling; jetting;

    Sammanfattning : ABSTRACTPowder injection moulding (PIM) is an important and accepted industrial technique for producing net-shaped components which combines the advantages of injection moulding and powder metallurgy. The properties of the feedstock, a mixture of powder and binder system (often based on a thermoplastic polymer), strongly influence the process. LÄS MER
