  2. 1. New Reactions with Allyl- and Allenylboron Reagents : Transition-Metal-Catalyzed and Transition-Metal-Free Carbon-Carbon Bond Formation Processes

    Author : Dong Wang; Kálmán J. Szabó; Jianbo Wang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon-carbon bond formation; cross-coupling; organoboron compound; allylboron reagent; allylation; transition metal; metal carbene; allenylboron reagent; transition metal free; diazo compound; tosylhydrazone; quinone; organisk kemi; Organic Chemistry;

    Abstract : Organoboron compounds have been widely used in carbon-carbon bond formation reactions in organic synthesis and catalysis. This thesis is focused on cross-coupling reactions of allyl-, allenylboronic acids and their ester derivatives via transition metal catalysis or transition-metal-free processes. READ MORE

  4. 2. Mind & Well-being : The relationships between personality and health related pathology

    Author : Markus J. T. de Ruijter; Helgi B. Schiöth; Gull Rukh; Hui Xin Wang; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; personality; epidemiology; cardiovascular disease; well-being; job satisfaction; autism spectrum disorder; animal models;

    Abstract : The study of the associations between personality, lifestyle and health related pathology has revealed important associations. These include associations with physical health such as the onset of cardiovascular disease, but also with mental and emotional health such as depression or life satisfaction. READ MORE

  5. 3. Walking efficiently with smart springs

    Author : Israel Luis; Elena Gutierrez-Farewik; Ruoli Wang; Benjamin J. Fregly; KTH; []
    Keywords : Musculoskeletal modeling and simulation; muscle-tendon biomechanics; muscle parameter calibration; metabolic energy models; gait analysis; exoskeleton assistance; biomechanics; Biomekanisk modellering och simulering; rörelseorganen; biomekanik; muskel; muskelmodell och muskelarkitektur; metabolisk energi och kostnad; gång; gånganalys; exoskelett; hjälpmedel; gångpatologi; Teknisk mekanik; Engineering Mechanics;

    Abstract : Numerous assistive exoskeletons have been developed in recent years to assist walking in individuals with and without motor disorders. A standard metric to measure the efficacy of assistance is the change in the metabolic energy cost between unassisted and assisted conditions. READ MORE

  6. 4. Ab initio studies of advanced functional materials with complex magnetism

    Author : Duo Wang; Biplab Sanyal; Roland Mathieu; Claude Ederer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Complex magnetism; 2D magnets; Functional material; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : For centuries, magnetism of materials has been an inevitable part of human civilization. Only in the last century, the mysteries of magnetism started to unfold thanks to the development of quantum theory of solids. READ MORE

  7. 5. Experimental Studies of Separated Flow and Heat Transfer in a Ribbed Channel
