2. 16. Microenvironmental control of malignant growth

   Author : Benedek Bozoky; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The tumor microenvironment (TME) comprises a complex milieu of different cell types, including cancer associated fibroblasts (CAFs) and immune cells, blood vessels, and the extracellular matrix. Through its interaction with cancer cells, it plays an essential role in cancer invasion and metastasis. READ MORE

   Abstract : The Driving to Learn project explored possible achievements of training people with cognitive disabilities in a joystick-operated powered wheelchair utilizing the grounded theory approach. Theoretical sampling led the concomitant collection and analysis of data. READ MORE

5. 18. Symphysis Fundus Measurements for Detection of Intrauterine Growth Retardation

   Author : Eva Bergman; Ove Axelsson; Helle Kieler; Max Petzold; Reynir Tomas Geirsson; Uppsala universitet; []
   Keywords : symphysis-fundus measurements; small for gestational age; intrauterine growth retardation; fetal growth; self-administered; relative growth; screening method; statistical surveillance; fetal surveillance;

   Abstract : A case-control study was performed to evaluate the Swedish population-based symphysis fundus (SF) reference curves. The study included 242 small for gestational age (SGA) neonates (169 term and 73 preterm infants) as cases and 296 non-SGA infants as controls. Two Swedish SF curves were evaluated. READ MORE

6. 19. Chlorophyll fluorescence as a biological feedback signal -for optimized plant growth conditions and stress diagnosis

   Author : Linnéa Ahlman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cucumber; indoor farming; abiotic stress; Fluorescence gain; ESC; biotic stress; basil; dynamics; strawberries; light spectrum; greenhouse lighting control; lettuce; powdery mildew Podosphaera aphanis; Pythium ultimum; LED; classification; lemon balm;

   Abstract : The use of light emitting diodes (LEDs) instead of traditional high pressure sodium lamps, in greenhouses and indoor growing facilities, enables tuning and optimization of both light intensity and light spectrum. This opens for an energy saving potential not possible otherwise. READ MORE

7. 20. Feedback Control of Spatially Evolving Flows

   Author : Espen Åkervik; Dan Stefan Henningson; Luca Brandt; Martin Berggren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stability; Control; Estimation; Absolute Convective instabilities; Model reduction; Fluid mechanics; Strömningsmekanik;

   Abstract : In this thesis we apply linear feedback control to spatially evolving flows in order to minimize disturbance growth. The dynamics is assumed to be described by the linearized Navier--Stokes equations. Actuators and sensor are designed and a Kalman filtering technique is used to reconstruct the unknown flow state from noisy measurements. READ MORE
