1. Buffer modification: A case study with polystyrene beads, DU145-, and MCF7 cell lines
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Separation of cancer cells gives advantages in understanding the disease, guiding treatment decisions, and facilitating drug development. Overall, separation plays an important role in biological research. Acoustophoresis is a technique that utilizes acoustic waves to separate particles and cells suspended in a buffer medium. LÄS MER
2. Ventilation systems in Low Energy Houses: augmentation of mixing in a small-scale water model by generating resonance
Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : Some passive houses are provided a warm supply flow inlet coming from a mechanical ventilation system, creating issues of shortcut ventilation as a result of an originated density layer stratification, since the supplied warm air is confined to the ceiling level. In this way, there exist several complaints of thermal discomfort and poor indoor environmental quality in passive houses. LÄS MER
3. Experimental study on stepped spray deflectors for planning hull
Master-uppsats, KTH/Marina systemSammanfattning : Planning vessels can reach high operational speeds thanks to their hull design. Some hull forms will develop large volumes of spray attached to the hull surface. The whisker spray is a thin layer consisting in droplets of water which can ac-count for a large proportion of the total resistance. LÄS MER
4. Evaluation of OSTE-hybrid materials for acoustophoresis applications
Master-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : This project aimed at exploring new hybrid materials to be used for acoustophoresis applications. Acoustophoresis can be used to manipulate particles inside a microfluidic channel by creating ultrasound standing waves within the channel [1]. This can be used for cell separation [2] or trapping of particles [3]. LÄS MER
5. Using CFD to investigate casue of vibrations in feed-water system
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : Computational fluid dynamics from large scale thermo-hydraulic simulation in 1D to large eddy simulation in 3D, were applied in this master thesis to study cause of vibrations in a feed-water system downstream the connected pumps. In the first step, the fluid flow of the pumps in RELAP5 simulations was disturbed by the blade passing sinusoidal vibrations to study their propagation in the piping system over time. LÄS MER
