1. 1. Beam-to-Beam Contact and Its Application to Micromechanical Simulation of Fiber Networks

   Författare :Hamid Reza Motamedian; Artem Kulachenko; Umberto Perego; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber network; beam-to-beam contact; rotational contact; non-consistent; simulation; finite element; multiscale; microscale; micromechanics; paper; refining; beating; fine; hygroexpansion; shrinkage; drying; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : This doctoral thesis covers the topic of modeling the three-dimensional fiber net- works with the finite element method. It contains the part addressing the numerical aspects of the modeling, namely, the contact formulation and application of the developed methods to the fundamental questions such as the effect of randomness in fiber properties and effect of fines and hygroexpansion.

3. 2. Advocates and Voices. Swedish patient associations, their importance to individuals with cancer and collaboration with health care

   Författare :Christina Carlsson; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; support; Patient associations; voluntary action perspective; cancer; membership; contact person; network; Cytologi; cancerology; oncology; Cytology; experiential knowledge; advocates; consumers involvement; voice of medicine; onkologi; voice of lifeworld;

   Sammanfattning : Patient associations (PAs) have an increasing impact for their members and for the health care system. This thesis studies PAs for cancer patients (PACPs) ? currently with over 20 000 members in Sweden ? regarding coverage, activities, and collaboration with the health care system with specific reference to the members? experiences.

4. 3. Cattle for beads : The archaeology of historical contact and trade on the Namib Coast

   Författare :Jill Kinahan; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Historical archaeology; contact; indigenous response; glass trade beads; commercial ceramics; nineteenth century; Namib coast; Arkeologi; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

   Sammanfattning : Early contacts between indigenous pastoralists at Walvis Bay on the Namib Coast and Western seafarers are poorly documented and little understood. Trade augmented regional exchange networks with a range, of archaeologically visible and easily identifiable objects. LÄS MER

5. 4. Rough surfaces in contact : artificial intelligence and boundary lubrication

   Författare :Marco Rapetto; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Sammanfattning : Interacting surfaces are found in mechanical systems and components. Since engineered surfaces are not perfectly smooth, only a fraction of the nominal surface area is actually in contact. This fraction is denoted as the real area of contact, Ar, and is formed by the sum of the contact spots between the two touching surfaces. LÄS MER

7. 5. Exploring the multiscale 3D architecture of human chromosome contact networks

   Författare :Dolores Bernenko; Ludvig Lizana; Martin Rosvall; Petter Holme; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; community detection; DNA 3D organization; Hi-C; network science; DNA-DNA contact data;

   Sammanfattning : Cells regulate genes to coordinate essential functions allowing cells to grow, divide, specialize, and respond to stresses. While regulatory proteins are the most common way to control these genes, the DNA’s 3D structure also plays a critical role as it affects how proteins access genes and how regulatory DNA elements interact over large genomic distances.
