  2. 1. Tight maps, a classification

    Author : Oskar Hamlet; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tight maps; Tight homomorphisms; Maximal representations; Toledo invariant; Bounded Kähler class; Hermitian symmetric spaces; Bounded cohomology; Hermitian symmetric spaces;

    Abstract : This thesis concerns the classification of tight totally geodesic maps between Hermitian symmetric spaces of noncompact type. In Paper I we classify holomorphic tight maps. We introduce a new criterion for tightness of Hermitian regular subalgebras. READ MORE

  5. 3. Walking the tight rope : Informal livelihoods and social networks in a West African city

    Author : Ilda Lourenço-Lindell; Katherine Gough; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; social networks; social capital; informal safety nets; informal sector; informalization; livelihoods; urban food; regulation; social change; structural adjutsment; Guinea-Bissau; West Africa; African cities; ADP; ADB;

    Abstract : Trends towards ‘informalization’ are looming large in the world today. African cities have long been characterised by the presence of an ‘informal sector’ but are now experiencing new waves of ‘informalization’. READ MORE

  6. 4. World oil supply and unconventional resources : Bottom-up perspectives on tight oil production

    Author : Henrik Wachtmeister; Mikael Höök; Roger Bentley; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oil supply; oil production; unconventional resources; tight oil; shale oil; bottom-up model; projections; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : Oil is the world’s largest primary energy source. It dominates the transportation sector which underpins the world economy. Yet, oil is a nonrenewable resource, destined not to last forever. In the mid-2000s global conventional oil production stagnated, leading to rising oil prices and fears of permanent oil scarcity.

  7. 5. Tight-Binding Modelling of Deep Eutectic Solvent-Based Lithium Battery Electrolytes

    Author : Mirna Alhanash; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; xTB; tight-binding; deep eutectic solvent; electrolyte.;

    Abstract : In recent years, there has been a growing interest in utilizing liquid electrolytes such as deep eutectic solvents (DES) as electrolytes for lithium batteries, owing to their numerous advantageous properties, including ease of preparation, tunability, wide electrochemical stability windows, and low vapor pressures. However, an aspect that remains poorly understood is the intricate relationship between the local structural symmetry, entropy, and the macroscopic properties of DES electrolytes. READ MORE
