  1. 11. Scarcity, Abundance and Sufficiency: Contributions to Social and Economic Theory

    Författare :Adel Daoud; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economics; sociology; scarcity; abundance; sufficiency;

    Sammanfattning : Economic sociology has established itself as a strong and vibrant field in the social sciences. A number of significant studies have been conducted on the relation between the economy and society: on firms, markets, networks, money, and general action theory. But little has been done on the issues of scarcity, abundance, and sufficiency (SAS). LÄS MER

  3. 12. Study of retention mechanisms in Hydrophilic Interaction Chromatography by Nuclear Magnetic Resonance Spectroscopy

    Författare :Adel Shamshir; Knut Irgum; Tobias Jonsson; Ngoc Phuoc Dinh; Torgny Fornstedt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HILIC; hydrophilic interaction chromatography; adsorption; STD-NMR; saturation transfer difference; retention mechanism; NMRD; solid state-NMR; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis deals with investigations of the retention mechanisms in hydrophilic interaction liquid chromatography (HILIC) using nuclear magnetic resonance spectroscopy. The aims are to understand how the different types of stationary phases can influence the retention of various solutes and the adsorption abilities of solvent on stationary phases. LÄS MER

  4. 13. Wellbore stability analysis based on a new true-triaxial failure criterion

    Författare :Adel Al-Ajmi; Robert Zimmerman; Bernt Aadnoy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failure criteria; Mogi failure criterion; intermediate principal stress; polyaxial test data; wellbore stability; Geoengineering and mining engineering; Geoteknik och gruvteknik;

    Sammanfattning : A main aspect of wellbore stability analysis is the selection of an appropriate rock failure criterion. The most commonly used criterion for brittle failure of rocks is the Mohr-Coulomb criterion. LÄS MER

  5. 14. Enabling Solutions for Integration and Interconnectivity in Millimeter-wave and Terahertz Systems

    Författare :Ahmed Adel Hassona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integration; Interconnects; Waveguide transitions; Embedded Wafer Level Ball Grid Array eWLB ; Electromagnetic band-gap EBG ; Millimeter waves; Packaging; Terahertz; Monolithicmicrowave integrated circuit MMIC ;

    Sammanfattning : Recently, Terahertz (THz) systems have witnessed increasing attention due to the continuous need for high data rate transmission which is mainly driven by next-generation telecommunication and imaging systems. In that regard, the THz range emerged as a potential domain suitable for realizing such systems by providing a wide bandwidth capable of achieving and meeting the market requirements. LÄS MER

  7. 15. Non-galvanic Interconnects for Millimeter-wave Systems

    Författare :Ahmed Adel Hassona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interconnects; THz; taper; waveguide transition; MMIC; InP; WR-6.5.; slot antenna; CMOS; eWLB; LTSA; finline; millimeter-wave; SiC; D-band; GaAs;

    Sammanfattning : Fueled by the increasing demand for higher data rates, millimeter-wave (mmW) systems emerged as a candidate that can provide multi-gigabit per second (Gb/s) transmission. This demand is mainly driven by modern communication systems and several other wireless and sensing applications such as production quality inspection and imaging systems. LÄS MER
