1. 1. Rheological changes at the air-liquid interface and examining different kind of magnetic needles

   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Fredrik Anderson; [2015]
   Keywords : Interfacial Shear Rheometer; rheometry; magentic needles; oscillation; surface chemistry; modulus; elastic; viscous; viscoelasticity; Reologi; elasticitetsmodul; oscillering; magnetiska nålar; viskositet; viskoelasticitet;

   Abstract : The main objective in this work was to learn how the instrument, the Interfacial Shear Rheometer (ISR400), worked and to investigate how the rheological properties, storage modulus (elasticity), G' and loss modulus (viscous), G'', changes when the surface pressure at the air-liquid interphase changes. The second objective were to examine the different kind of magnetic needles used in the experiments and to conclude which type of needle is best for its specific field of analysis. READ MORE

3. 2. Relationships Between Skin Properties and Body Water Level

   University essay from KTH/Medicinsk teknik

   Author : Ida Andersson; Anders Hedvall; [2013]
   Keywords : 22 MHz; body water level; correlations; Cutometer; dehydration; distensibility; elasticity; humans; immediate elastic deformation; mechanical properties; skin; thickness; ultrasound; viscoelasticity; 22 MHz; Cutometer; dehydrering; direkt elastisk deformation; elasticitet; hud; korrelationer; kroppens vattennivå; mekaniska egenskaper; människor; tjocklek; töjbarhet; ultraljud; viskoelasticitet;

   Abstract : A need for a quantitative method to determine body water level has been identified by a team of Clinical Innovation Fellows at the Centre for Technology in Medicine and Health (CTMH). A reliable way to determine body water level would bring great benefits to the healthcare sector, where no optimal method is available at the time of writing. READ MORE
