  2. 1. Inner strength among the oldest old : a good aging

    Author : Björn Nygren; Berit Lundman; Astrid Norberg; Ingegerd Fagerberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aged; aging; development; health; inner strength; oldest old; resilience; Nursing; Omvårdnad;

    Abstract : The overall purpose of this thesis is to describe, explore and illuminate inner strength among the oldest old. The thesis has a salutogenic perspective where strengths and health are in the foreground instead of weakness and ill health. The thesis is part of The Umeå 85+ study and comprises four studies with both quantitative and qualitative data. READ MORE

  4. 2. The Formation and Breakdown of Passive Film on Ni Alloys : in situ synchrotron studies

    Author : Alfred Larsson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Passivity; Corrosion; Degradation; Nickel alloys; synchrotron; in situ; Fysicumarkivet A:2023:Larsson;

    Abstract : Corrosion results in huge annual costs and a large environmental footprint. The corrosion rate of some alloys can be made negligible by the presence of a spontaneously forming oxide film on the surface, a so-called passive film. Famous examples of alloys exhibiting passivity are stainless steels. READ MORE

  5. 3. Vehicle emissions abatement: NO oxidation and ammonia SCR

    Author : Xavier Auvray; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SpaciMS; NO oxidation; Cu-Beta zeolite; sulfur dioxide; Platinum; ammonia SCR; aging;

    Abstract : The design and the development of catalytic systems for reducing vehicle emissions is a complex task due to the variety of components in a wide range of gas flow and temperature. A complete system is, therefore, composed of a series of catalysts or catalytic systems, each of which is dealing with a particular aspect of the abatement process. READ MORE

  6. 4. Structure and Dynamics of Silica Dispersions and Gels

    Author : Jonas Nordström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aging; Photon correlation spectroscopy; sodium silicate; lithium electrolytes; water glass; fumed silica; sol-gel transition;

    Abstract : This thesis deal with the sol-gel transition of two quite different systems, both based on silica. The overall aim is to understand what interactions lead to this sol-gel transition and how the structure and dynamics change as a result of this.The first project concern the gelation of water glass, also known as alkaline sodium silicate solutions.

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

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

    Abstract : 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.
