  2. 6. Aerosol Metal Nanoparticles and their Role in Particle-Assisted Growth of III–V Nanowires

    Author : Robert Hallberg; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerosol formation; III–V semiconductor materials; catalyst particles; Palladium nanoparticles; Gold nanoparticles; Spark discharge generation; MOVPE; MOCVD; Transmission electron microscopy TEM ; Phase stability; Nanoparticle deposition; Nanoparticle generation; nanoparticles characterization; Nanowire NW ; Nanowire growth;

    Abstract : Semiconductor nanowires have properties that make them potentially useful for applications in future electronic, photovoltaic, and optoelectronic devices. A powerful nanowire fabrication technique is the use of a nanoparticle as a preferential nucleation site, from which a nanowire grows. READ MORE

  4. 7. Modelling and simulation of factors influencing on-site construction of concrete frameworks : Studying the effects of resource allocation, weather conditions, and climate-improved concrete

    Author : Robert Larsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete-event simulation DES ; Concrete; Structural frames; Productivity; Resource use; Weather; Carbon Emissions;

    Abstract : Concrete is the most common material used to build the structural framework in multistory buildings. However, the construction works carried out on the building site are affected by many different factors that may reduce productivity. READ MORE

  5. 8. Cold atoms in a variety of optical lattice potentials

    Author : Robert Saers; Umeå universitet; []
    Keywords : ;

    Abstract : In this thesis, both experimental achievements and theoretical preparatory investigationsfor future experiments are introduced. The experiments presentedare performed with the set-up used for laser cooling and trapping of rubidiumatoms, and the theoretical examinations are adopted for intended experimentson Bose-Einstein Condensates.

  6. 9. Lifestyle and glycaemic control before and after the onset of type 2 diabetes

    Author : Robert Koivula; Genetisk och molekylär epidemiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Prediabetes; Obesity; Beta-cell Function; Insulin Sensitivity; Physical Activity; Exercise; Diet; Lifestyle; Ectopic Fat; Genetic Epidemiology; Genetic Risk; Biomarker; Precision Medicine;

    Abstract : Type 2 diabetes (T2D) is a complex disease with widespread physiological insults to the regulation of metabolic homeostasis, above all glycaemic regulation. The pathogenesis of T2D and its progression is broadly understood to be through a gradual decrease in peripheral insulin sensitivity, a compensatory rise in insulin secretion, and a gradual decline in beta-cell function, resulting in glycaemic dysregulation and eventual T2D.

  7. 10. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution

    Author : Robert Almstrand; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AOB; NOB; biofilms; image analysis; FISH; Nitrosomonas; population dynamics; spatial distribution;

    Abstract : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. READ MORE
