  2. 1. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach

    Author : Linda Ta; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aerobic oxidation; ionic liquid; sustainability; NHC catalysis; oxidative NHC catalysis; green chemistry; OTHO; Organocatalysis;

    Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE

  4. 2. Organocatalytic Transformations with N-Heterocyclic Carbenes - An Investigation of Ionic Liquids as NHC Precatalysts and Aerobic Oxidative Esterifications

    Author : Linda Ta; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene; ionic liquid; multi-component reaction; aerobic oxidation; OTHO; Organocatalysis; green chemistry;

    Abstract : The call for more sustainable processes in the chemical society has led to the development of the field of green chemistry. The Twelve Principles of Green Chemistry serve as guidelines for the design of processes. READ MORE

  5. 3. The brain-pituitary-gonadal axis of the three-spined stickleback, Gasterosteus aculeatus

    Author : Yi Ta Shao; Bertil Borg; Sylvie Dufou; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BPG axis; GnRH; lh-β; fsh-β; three-spined stickleback; Gasterosteus aculeatus; homeostasis; feedback; funktionell zoomorfologi; Functional Zoomorphology;

    Abstract : The seasonal reproduction of the three-spined stickleback is stimulated by long day photoperiod. As in other vertebrates, the reproductive system of stickleback is regulated by the brain-pituitary-gonadal (BPG) axis which is largely controlled by feedback effects. Both negative and positive feedback effects on the BPG axis have been found in fish. READ MORE

  6. 4. Transactional Analysis Psychotherapy : Three Methods Describing a Transactional Analysis Group Therapy

    Author : Roland Johnsson; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transactional analysis psychotherapy; TA; diagnosis; psychotherapy method; alliance;

    Abstract : Transactional Analysis Psychotherapy - Three Methods Describing a Transactional Analysis Group Therapy The overall aim of the present thesis was to enhance and revive the practical understanding of the active ingredients in Transactional Analysis Psychotherapy (TA) and to define and lay down elements of TA, which makes it a distinct and replicable method of treatment. The thesis includes three empirical studies of a videotaped one-year long TA Group Therapy with 10 clients. READ MORE

  7. 5. Study of Electrochemical Behaviour and Corrosion Resistance of Materials for Pacemaker Lead Applications
