1. 36. Portraying Unease : the Art and Politics of Uncomfortable Attachments

   Författare :Ellen Suneson; The Cultural Studies Group of Neuroscience; []
   Nyckelord :HUMANIORA; HUMANITIES; emotional responses; contemporary art; performance art; affect theory; feminist theory; queer feminist theory; visual methodology; embarrassment; attachment; hope; subversion; repair; self-doubt; institutional attachment; institutional promises;

   Sammanfattning : Portraying Unease critically discusses a tendency amongst politicized scholars to endow artworks with traits of subversion and political productivity. Artworks that address structural discrimination, such as heterosexism, racism, or ableism, are often described as possessing qualities that can challenge unjust systems or initiate political change.

3. 37. Circular Business Models that Extend Product Value : Going Beyond Recycling to Create New Circular Business Opportunities

   Författare :Katherine Whalen; Internationella miljöinstitutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular business model; product life extension; obsolescence; circular economy; business model; reuse; repair; refurbishment; sustainability strategies; sustainability education;

   Sammanfattning : Over the past ten years, significant industry, policy, and scientific attention has been given to the ‘circular economy’, which aims to create a more sustainable society by decoupling economic growth from resource consumption. Firms are expected to play a significant role in the shift to a circular economy model by implementing circular business models that encourage prolonged use of products, components, and materials.

4. 38. Clinical Aspects on Chimney Stent Graft Technique in Endovascular Repair of the Aorta

   Författare :Adel BinJabr; Vaskulära sjukdomar - kliniska studier; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chimney stent graft; chimney graft; chimney graft technique; snorkel technique; endovascular aortic repair; thoracic endovascular aortic repair; endoleak; patency; rupture; urgent; stent-graft; stent; graft; aorta; computed tomography; ultrasound; stenosis; EVAR; TEVAR; CTA; MRI; AAA; TAAA; supraaortic; visceral; aneurysm; dissection; mycotic infection; stent-graft infection; follow-up; endovascular complication; sandwich technique; periscope graft; periscope graft technique.;

   Sammanfattning : Introduction: Open repair of the aorta carries a high risk for morbidity and mortality especially in the elderly population and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. LÄS MER

5. 39. Thermo-Mechanical-Metallurgical Modelling of Pearlitic Steels and Railhead Repair Welding

   Författare :Björn Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pearlitic steels; Railhead repair; Welding simulations; Phase transformations; Cyclic plasticity; Finite element analysis; Homogenisation;

   Sammanfattning : The efficiency of rail transport is attributed to low rolling resistance, which comes at the cost of high contact pressures between rail and wheel. Consequently, both the rail and wheel can be susceptible to fatigue crack initiation and propagation due to the resulting high stresses and large number of load cycles in service. LÄS MER

7. 40. DNA precursor asymmetries, Mismatch Repair and their effect on mutation specificity

   Författare :Robert Buckland; Andrei Chabes; Juan Méndez; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA Replication Fidelity; Mutations; dNTP pools; Mismatch Repair; Checkpoint; Ribonucleotide Reductase; Msh2; medicinsk biokemi; Medical Biochemistry; molekylärbiologi; Molecular Biology;

   Sammanfattning : In order to build any structure, a good supply of materials, accurate workers and quality control are needed. This is even the case when constructing DNA, the so-called “Code of Life.” For a species to continue to exist, this DNA code must be copied with incredibly high accuracy when each and every cell replicates.
