2. 1. Mircostructure and rheological properties of concentrated tomato suspensions during processing

   Author : Elena Bayod; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheology; microstructure; morphology; flocs; tomato paste; ketchup; fibre suspensions; viscoelastic properties; particle size distribution; time dependency; network; yield stress; wall slip; Mooney; Cox-Merz rule; Tikhonov; tube viscometer; rotational viscometer; homogenisation; shearing;

   Abstract : Food processing comprises operations such as dilution (changing the concentration), homogenisation (changing the particle size), and subsequent pumping (shearing), among others. It is thus of great interest to gain a better understanding of the mechanisms governing the creation and disruption of structures during these engineering operations, and the way in which they are related to the textural and rheological properties of the material.

4. 2. Candidate biomarkers for synaptic pathology: neurogranin, neuroligins and neurexins in neurodegenerative disorders

   Author : Elena Camporesi; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Synaptic dysfunction; Alzheimer’s disease; Biomarkers; Neurogranin; Neurexins; Neuroligins; Cerebrospinal fluid; Brain tissue;

   Abstract : Synapses are small units through which neurons communicate in the brain. They represent the site of memory formation and cognitive abilities and are thus primarily affected by neurodegenerative diseases such as Alzheimer’s disease (AD), the leading cause of dementia in the elderly population.

5. 3. Bivalve shells as environmental archives

   Author : Elena Dunca; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Historical Geology and Paleontology; historisk geologi och paleontologi;

   Abstract : Bivalves can be used as environmental biomonitors by studying the growth rate and the structure of their shells, as well as by analysing elemental distribution in the shells. Information about water chemistry, temperature and pH, about precipitation, food supply and other environmental parameters are stored in the bivalve shells. READ MORE

6. 4. Pressure-driven flows in thin and porous domains

   Author : Elena Haller; Peter Wall; John Fabricius; Johan Byström; Eduard Marušic-Paloka; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Mathematics; Tillämpad matematik;

   Abstract : The present thesis is devoted to the derivation of Darcy's law for incompressible viscous fluid flows in perforated and thin domains by means of homogenization techniques.  The problem of describing asymptotic flows in porous/thin domains occurs in the study of various physical phenomena such as filtration in sandy soils, blood circulation in capillaries, lubrication and heationg/cooling processes.

7. 5. Composition and maintenance of skin resident T-cells in health and disease

   Author : Elena Hoffer; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Tissue-resident memory T cells (TRM) reside in healthy skin at sites of previous infections. Upon re-infection, TRM cells rapidly respond by initiating tissue inflammation and exert effector functions to eliminate pathogens. TRM cells are potent effector cells and as such, they are key players in focal inflammatory skin diseases. READ MORE
