  2. 1. Response of Bolivian Altiplano Lakes to Seasonal and Annual Climate Variations

    Author : Ramiro Pillco; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENSO; terminal lake; bathymetry; lake level; water balance; lake routing; paleolakes; climate change; precipitation pattern; intermittent rivers.; Desaguadero River; Lake Titicaca; Lake Poopó;

    Abstract : The Bolivian Altiplano is situated between two mountain ranges, the western and eastern central Andes in South America. It has two major lakes, Lake Titicaca to the north, and Lake Poopó to the south, which both are important for the nature as well as for the living conditions on the Altiplano. The two lakes are the remnants of large paleolakes. READ MORE

  4. 2. C2- and C3-symmetric ligands via ring-opening of aziridines

    Author : Fredrik Lake; KTH; []
    Keywords : asymmetric catalysis; aziridine; benzaldehyde; diethylzinc; enantionselective; ligand; proazaphosphatrane; ring-opening; sulfonamide; symmetry; titanium; nicronium;

    Abstract : This thesis deals with the design and synthesis of chiralenantiopure nitrogencontaining ligands and the use of theseligands in asymmetric catalysis. A modular synthetic approachto enantiopure nitrogen-containing ligands was developed. Thesynthetic method is based on the ring-opening of activatedchiral aziridines by nitrogen nucleophiles.

  6. 4. Cytoplasmic mRNP particles in dormant and developing artemia embryos

    Author : Mats Lake; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In dormant cryptobiotic embryos of Artemia there is a stored pool of messenger RNA (mRNA) associated with the endoplasmic reticulum. Upon resumption of the embryos this latent mRNA is activated and used in the protein synthesis. READ MORE

  7. 5. Recombination frequencies in hybrid females of inbred lines of Drosophila melanogaster

    Author : Staffan Lake; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The intention of the present study was to examine the effect of the maternal genome and cytoplasm, of the attachment of extra heterochromatin of the transposing of heterochromatic regions into euchromatic parts and of temperature shocks during various stages of the development on recombination in Drosophila metanogaster. The access to marker genes along the X-chromosome induced in the inbred line made it possible to examine this array of different conditions in females with an isogenic background. READ MORE
