  2. 1. Growth hormone and somatolactin function during sexual maturation of female Atlantic salmon

    Author : Susana Benedet Perea; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Growth hormone; somatolactin; insulin-like growth factor I; GH; SL; IGFI; GHR; SLR; IGFIR; ovary maturation; reproduction; Atlantic salmon; spawning; pituitary;

    Abstract : Background and aims: The growth hormone-insulin-like growth factor I (GH-IGF-I) system is known to act during sexual maturation of female salmonids, but the specific roles are not known. Somatolactin (SL) is a pituitary hormone closely related to GH and is only found in fish. In some species, including salmonids, there are two forms, SLa and SLß. READ MORE

  4. 2. Simple sl_{n+1}-module structures on U(h)

    Author : Jonathan Nilsson; Volodymyr Mazorchuk; Olivier Mathieu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : We study the category M consisting of U(sl_{n+1})-modules whose restriction to U(h) is free of rank 1, in particular we classify isomorphism classes of objects in M and determine their submodule structure. This leads to new sl_{n+1}-modules. READ MORE

  5. 3. Agpaitic Rocks of the Norra Kärr Alkaline Complex: Chemistry, Origin, and Age of Eudialyte-hosted Zirconium and Rare-earth Element Ore

    Author : Axel S.L. Sjöqvist; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Norra Kärr alkaline complex; agpaitic rocks; eudialyte; rare-earth elements; geochronology; radiogenic isotope geochemistry;

    Abstract : Agpaites are peralkaline nepheline syenites that are denominated by rock-forming complex silicate minerals such as eudialyte. The exotic mineralogy and chemistry of these rocks are not only interesting for research, but globally these rocks also have potential as polymetallic resources of elements such as zirconium, niobium, rare-earth elements, zinc, and uranium.

  6. 4. Response of marine food webs to climate-induced changes in temperature and inflow of allochthonous organic matter

    Author : Rickard Degerman; Agneta Andersson; Risto Lignell; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; bacterial production; mesocosm; food web efficiency; Baltic Sea;

    Abstract : Global records of temperature show a warming trend both in the atmosphere and in the oceans. Current climate change scenarios indicate that global temperature will continue to increase in the future. The effects will however be very different in different geographic regions. READ MORE

  7. 5. Irreducible Representations of Quantum Affine Algebras

    Author : Jesper Thorén; Matematik (naturvetenskapliga fakulteten); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Number Theory; Matematik; Mathematics; quantum evaluation modules; highest weight representations; quantum Yang-Baxter equation; quantum affine algebras; quantum groups; comultiplication; Hopf algebras; affine Lie algebras; field theory; algebraic geometry; algebra; group theory; Talteori; fältteori; algebraisk geometri; gruppteori;

    Abstract : We construct finite-dimensional representations of the quantum affine algebra associated to the simple finite-dimensional Lie algebra sl(n+1). The module structure is defined on the vector space tensor product of the fundamental representations of the quantum affine algebra. READ MORE
