  1. 6. Optical spectroscopy of impurity atoms in semiconducting Nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Shishir Shroff; [2017]
    Keywords : Photoluminescence; Nanowire; Defects; Diffusion; GaAs; Copper; Physics and Astronomy;

    Abstract : In a small and confined one dimensional geometry of nanowire, even few defects can influence the performance of the devices. Main objective of this thesis is to conduct photoluminescence study of such defect states in GaAs nanowires, which we will first introduce by diffusing copper impurity atoms, in very low concentrations.

  3. 7. Evaluation of Methods for Obtaining an Image Derived Input Function from Dynamic PET-images

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Radiofysik

    Author : Sofia Jonsson; [2016]
    Keywords : ;

    Abstract : Dynamic PET is a technique to follow the uptake kinetics of radioactive labelled molecules in the human body. The kinetic behaviour may be analysed to acquire parameters, such as perfusion of blood to tissue, with the knowledge of the blood activity time curve (also called input function). READ MORE

  4. 8. Dissolution kinetic study of limonene in supercritical carbon dioxide by in-situ Raman spectroscopy

    University essay from Lunds universitet/Kemiska institutionen

    Author : Cristiana Buzolin; [2016]
    Keywords : limonene; Raman spectroscopy; supercritical carbon dioxide; dissolution kinetics; solubility; analytical chemistry; analytisk kemi; Chemistry;

    Abstract : Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature.

  5. 9. Volume Kinetic Models for Perioperative Fluid Therapy

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Pehr Wessmark; Viktor Winther; [2015]
    Keywords : Volume kinetics; Population volume kinetics; Fluid therapy; Interstitial fluid expansion; 0.9% saline;

    Abstract : Intravenous fluid infusion during surgeries is based on clinical practice guidelines. Many factors impact the fluid distribution in the body, mainly the effect of anesthetic gases and surgical stress. Volume kinetics is a method to simulate the distribution and elimination of infusion fluids by considering the dilution of plasma over time. READ MORE

  6. 10. Amyloid Nucleation in Presence of Crowders

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Jonas Wessén; [2014]
    Keywords : nucleation; molecular self-assembly; protein physics; statistical mechanics; thermodynamics; fibrilation kinetics; Monte Carlo; Huntington s; Parkinson s; Alzheimer s; molecular crowding; amyloid fibrils; amyloid; protein aggregation; Physics and Astronomy;

    Abstract : During the last few years, crowding effects on the physics of proteins has become an increasingly popular topic of research. This is is because most biological processes involving proteins naturally take place in a crowded environment, e.g. in the cellular environment where macromolecules may occupy 30% of the volume.
