21. Fabrication, functionalization and electrical conductance modulation of nanoparticle based molecular electronic Nano-devices
Sammanfattning : Over the years many techniques have been proposed for the purpose of the formation of electrically conducting metal-molecule-metal junctions. One such technique utilizes gold-nanoparticles (AuNPs) that could assist in contacting small molecules between large gaps. LÄS MER
22. Inverse ration ventilation : experimental studies on pulmonary integrity and gas exchange
Sammanfattning : In this thesis, pulmonary and circulatory effects of inverse ratio ventilation (IRV) have been studied experimentally. Comparisons have been made between volume and pressure controlled IRV and conventional ventilation under conditions of equal minute ventilation and end-expiratory alveolar pressure levels. LÄS MER
23. Regional ventilation, pulmonary perfusion and gas exchange in supine and prone positions
Sammanfattning : The rationale for treating patients with acute lung injury in the prone position springs from a number of observations. Clinical reports have documented improved oxygenation when patients are turned prone. Regional vascular conductance is higher in dorsal lung regions regardless of posture. LÄS MER
24. Effects of future climate on carbon assimilation of boreal Norway spruce
Sammanfattning : In boreal forests, the main factors limiting biomass production are the harsh climate, which combines a short growing season and low annual levels of incoming solar energy, and the limited availabilit... mery of nitrogen. LÄS MER
25. A Treatise on the Geometric and Electronic Structure of Clusters : Investigated by Synchrotron Radiation Based Electron Spectroscopies
Sammanfattning : Clusters are finite ensembles of atoms or molecules with sizes in the nanometer regime (i.e. nanoparticles). This thesis present results on the geometric and electronic structure of homogeneous and heterogeneous combinations of atoms and molecules. LÄS MER
