   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : With the high use of online social networks we are entering the era of big data. With limited resources it is important to evaluate and prioritize interesting data. This thesis addresses the following aspects of social network analysis: efficient data collection, social interaction evaluation and user privacy concerns. LÄS MER

5. 4. A close-up on neutrophils : Visualizing the mechanisms of their in vivo recruitment and function

   Författare :Sara Massena; Mia Phillipson; Randall S. Jonhson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; chemokine; chemotactic gradient; citrullination; hypoxia; inflammation; intraluminal crawling; intravital imaging; PAD enzymes; permeability; proangiogenic; proinflammatory;

   Sammanfattning : A successful immune response depends on prompt and sufficient recruitment of leukocytes from the circulation to infected or injured sites. Mobilization of leukocytes to hypoxic tissues is vital for angiogenesis, i.e. the formation of new blood vessels from preexisting vasculature, and thus crucial for tissue growth and regeneration.

7. 5. Enabling Surface Cleaning Robot for Large Food Silo

   Författare :Kinan Dandan; Amy Loutfi; Lars Karlsson; Mikael Ekström; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Confined space; surface cleaning robot; motion control; static and dynamic analysis;

   Sammanfattning : Working conditions in the dry cleaning and sanitation of confined interior spaces are often extreme, and workers need overall protection with tight clothing, helmets, face mask, earmuffs, and respirators. The environment is dirty, noisy with bad visibility and heavy with a high static work load. LÄS MER
