1. 1. Self-Healing Concrete

   Författare :Magdalena Rajczakowska; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Hans Hedlund; Erik Schlangen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cementitious materials; self-healing; exposure; fly ash; calcite; C-S-H; cracking; Byggmaterial; Building Materials;

   Sammanfattning : Concrete is a brittle material prone to cracking due to its low tensile strength. Crack repairs are not only expensive and time-consuming but also increase the carbon footprint. Designing a novel concrete material possessing the ability to self-repair cracks would enhance its sustainability. LÄS MER

   Sammanfattning : This thesis analyse how life-histories are expressed and reformulated in connection to a life crisis of ill health. The study is based on ten interviews with people who in connection with ill health have made use of treatments within both orthodox medicine and complementary medicine and who have also developed various forms of self-treatment.

4. 3. Investigation on the self-healing capabilties of asphaltic materials using neutron imaging

   Författare :Adrian Markari; Nicole Kringos; Anders Kaestner; Romain Balieu; Lily Poulikakos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-healing; bituminous materials; neutron imaging; sample size effect; reconstruction; image processing; volumetric analysis; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Sammanfattning : Bitumen acts as a binding agent in asphalt mixtures where it binds the aggregates together. It is known for its potential to heal small cracks and recover its mechanical properties under the right conditions. Though this self-healing property is known, there is currently a lack of knowledge about the mechanisms that drive the process. LÄS MER

5. 4. Santería healing in Cuba

   Författare :Johan Wedel; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; anthropology; Cuba; Santería; Afro-Cuba; religious healing; medical anthropology; medicine; rituals;

   Sammanfattning : In Cuba, from the early twentieth century up until today, the Afro-Cuban religious tradition santería has stood for health, protection, and a meaningful life for many Cubans. Santería, which has its roots in Africa and the religious beliefs of the Yoruba slaves, is currently flourishing, with both Cubans and foreigners turning to it for help in instances of ill-health.

7. 5. On the quantification of healing in asphalt materials

   Författare :Remya Varma; Nicole Kringos; Romain Balieu; Lily Poulikakos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Healing; bitumen; mastic; viscoelastic strain; viscoplastic strain; fracture; creep and recovery; Läkning; bitumen; mastic; viskoelastisk töjning; viskoplastisk töjning; brott; kryp and återhämtning; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Sammanfattning : Asphalt materials exhibit self-healing characteristics. In order to evaluate the healing capabilities of these materials, numerous investigations are carried out by researchers. These investigations include various definitions of healing and mechanical test methods to quantify the extent of healing. LÄS MER
