1. 16. Topics in geometry, analysis and inverse problems

   Författare :Hans Rullgård; Mikael Passare; Victor Palamodov; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laurent series; Harnack curves; differential equations; tomography; Mathematical logic; Matematisk logik;

   Sammanfattning : The thesis consists of three independent parts.Part I: Polynomial amoebasWe study the amoeba of a polynomial, as de ned by Gelfand, Kapranov and Zelevinsky. A central role in the treatment is played by a certain convex function which is linear in each complement component of the amoeba, which we call the Ronkin function. LÄS MER

   Sammanfattning : DIGITAL ANALYSIS OF CARDIAC ACOUSTIC SIGNALS IN CHILDREN Milad El-Segaier, MD Division of Paediatric Cardiology, Department of Paediatrics, Lund University Hospital, Lund, Sweden SUMMARY Despite tremendous development in cardiac imaging, use of the stethoscope and cardiac auscultation remains the primary diagnostic tool in evaluation of cardiac pathology. With the advent of miniaturized and powerful technology for data acquisition, display and digital signal processing, the possibilities for detecting cardiac pathology by signal analysis have increased.

4. 18. Finite Element Analysis of Case-Hardened Roller Bearings

   Författare :Jan Pettersson; Roland Fortunier; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis deals with the material modelling of case-hardened bearing steel, with special reference to hardened roller bearing components. The result of a case-hardening process is a hardened component with substantially improved material properties within a restricted region beneath the heat-treated surface. LÄS MER

5. 19. Assembling a toolkit for computational dissection of dense protein systems

   Författare :Daniel Nilsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; macromolecular crowding; liquid-liquid phase separation; Monte Carlo simulation; time-lagged independent component analysis; finite-size scaling; polymer field theory; protein force field; Fysicumarkivet A:2021:Nilsson;

   Sammanfattning : The cellular interior is a dense environment. Understanding how such an environment impacts the properties of proteins and other macromolecules, as well as how weak, non-specific interactions drive processes such as protein droplet formation through liquid-liquid phase separation, is a major challenge in biological physics.

7. 20. Feber i interaktion : Kropp, kunskap och legitimitet i svenska primärvårdssamtal

   Författare :Klara Bertils; Anna Lindström; Helen Melander Bowden; Camilla Lindholm; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; conversation analysis; medical interaction; epistemics; multimodality; joint activity; nurse-patient; fever; conversation analysis; samtalsanalys; vårdkommunikation; kunskap; multimodalitet; gemensamma aktiviteter; sjuksköterska-patient; undersköterska-patient; feber; Linguistics; Lingvistik;

   Sammanfattning : This thesis explores the social and interactional dimensions of fever and body temperature. Using the theoretical and methodological framework of Conversation Analysis, this thesis investigates how patients and healthcare professionals talk about fever, measure body temperature and negotiate the significance of temperature measurements in acute primary care encounters.
