  2. 1. Prenatal risk factors for severe cardiovascular diseases up to middle-age : a Nordic collaborative study

    Author : Fen Yang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background and objectives: Cardiovascular diseases (CVDs) are major causes of death and disability. However, the established traditional risk factors cannot explain a substantial proportion of CVD cases, prompting investigations into novel risk factors. READ MORE

  4. 2. Short- and long-term neuronal plasticity in hippocampal CA1 region of rat

    Author : Fen-Sheng Huang; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glutamate; hippocampus; plasticity; synapse; LTP; LTD; AMPA; NMDA;

    Abstract : The brain is highly plastic, displaying both short- and long-term changes, resulting from developmental processes as well as learning and memory. Moreover, short-term plasticity such as paired pulse facilitation and depression (PPF, PPD) have long been used to monitor the presynaptic versus postsynaptic changes occurring during more lasting processes such as long-term potentiation and depression (LTP, LTD).

  5. 3. Equal Peace : United Nations Peace Operations and the Power-Relations between men and women in Timor-Leste

    Author : Louise Olsson; Peter Wallensteen; Mats Hammarström; Fen Osler Hampson; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; United Nations; Peacekeeping; Peace Operations; Peacebuilding; Equality; Timor-Leste; Peace and conflict research; Freds- och konfliktforskning;

    Abstract : This dissertation expands the inquiry of United Nations peace operations to incorporate their effects on gender power-relations of the host state. To achieve this, a mainstream-based analytical framework, additionally informed by suggestions from feminist research, was formulated and applied to the case of Timor-Leste. READ MORE

  6. 4. Towards a changed view on greenhouse gas exchange in the Arctic: new findings and improved techniques

    Author : Mikhail Mastepanov; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; methane; carbon dioxide; greenhouse gas; chamber; Arctic; fen; permafrost;

    Abstract : Arctic ecosystems represent an important component in the global terrestrial exchange of greenhouse gases and energy with the atmosphere. In the changing climate, which is most pronounced in the Arctic, the possible scenarios of greenhouse gas exchange response should be seriously considered in predictive climate modelling efforts.

  7. 5. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions

    Author : Mats Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; O2; CO; ionization potential; Con; Fen; NO; sticking probability; laser ionization; D2; Wn; Cun; Rhn; reaction probability; cluster; jellium model; Nbn; metal cluster reactivity; N2; time-of-flight mass spectrometry; Nin;

    Abstract : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. READ MORE
