  2. 1. Parameters Controlling Distribution of Diagenetic Alterations within Fluvial and Shallow Marine Sandstone Reservoirs : Evidence from the Libyan Basins

    Author : Muftah Khalifa; Hemin Koyi; Joao Marcelo Medina Ketzer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diagenesis; Structural setting; Depositional facies; Basin thermal history; Ther- mal Hot basinal brines; Fluid inclusions; Raman Spectrometry; Stylolites; Hydro-carbon migration; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : This thesis demonstrates that geological setting, depositional facies, open system flux of hot basinal brines and descending of shallow waters have a strong impact on the distribution of the diagenetic alterations within continental and paralic/shallow marine sandstones which in turn control the quality and heterogeneities of the reservoirs.Geological setting controls the mineralogical and textural maturity of sandstone, whereas depositional facies control the pore water chemistry (marine, brackish or meteoric), sedimentary texture and sand body geometry.

  4. 2. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends

    Author : Olof Bäcke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosslinking; fullerene crystals; tomography; transmission electron mi- croscopy; organic solar cell; in situ; polymer:fullerene film; thermal degradation;

    Abstract : Polymer:fullerene bulk-heterojunction thin films show great promise for use as active layers in organic solar cells. However, their low thermal stability is a hindrance that complicates the manufacturing and influences the lifetime of devices. READ MORE

  5. 3. Logistics Systems for Recycling - Efficient Collection of Household Waste

    Author : Marianne Jahre; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste col lection systems; reverse distribution; green logistics; collection; reverse logistics; recycling; environment; waste;

    Abstract : This dissertation investigates collection and recycling of household waste with focus on packaging materials.

  6. 4. Robot Path Planning

    Author : Robert Bohlin; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of three papers concerned with the basic path planning problem for robots moving in a known static environment. Our main interest has been industrial robots, but the methods are general and apply to a wide range of robots. READ MORE

  7. 5. Isotope enrichment by countercurrent electromigration in molten salts

    Author : Arnold Lundén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A series of isotope enrichments by electromigration in molten saltslias been carried out during the last, years. The running conditions aresummarized in table 1 and the enrichments achieved are given intables 2—13. Practical details such as the arrangement of the electricalcircuits and the construction of the separation columns are discussed. READ MORE
