  1. 16. Retrofitted Solar Domestic Hot Water System for Single-Family Electrically-Heated Houses: Development and testing

    Författare :Ricardo Bernardo; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar domestic hot water; retrofitting; single family electrically heated houses; high solar fraction; photovoltaic thermal concentrating hybrids; PVT; parabolic reflectors; CPC thermal collector.;

    Sammanfattning : In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. LÄS MER

  3. 17. Identification of the common eliminated region (CER1) by the microcell hybrid based 'elimination test'

    Författare :Ying Yang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Elimination test; common eliminated region 1 CER1 ; 3p21.3; microcell hybrids; tumor suppressor gene; LF lactoferrin ; LIMD1 LIM-domain containing gene 1 ; sequencing; MMCT microcell mediated chromosome transfer ; real time PM methylation;

    Sammanfattning : The aim of elimination test (Et) is to identify tumor antagonizing genes from chromosome regions that are regularly deleted in microcell hybrid (MCH) derived tumors through serial SCID mice passages. Et so far was focused on the short arm of human chromosome 3 (chr 3) due to its frequent deletions in 21 tumor types including renal cell carcinoma (RCC), small cell lung carcinoma (SCLC) and breast cancer (BRC).

  4. 18. Growth and Behaviour : Epigenetic and Genetic Factors Involved in Hybrid Dysgenesis

    Författare :Wei Shi; Reinald Fundele; Diethard Tautz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Interspecies hybridization; hybrid dysgenesis effect; speciation; genomic imprinting; epigenetics; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : In mammals, the most frequently observed hybrid dysgenesis effects are growth disturbances and male sterility. Profound defects in placental development have been described and our work on hybrids in genus Mus has demonstrated putative hybrid dysgenesis effects that lead to defects in lipid homeostasis and maternal behavior.

  5. 19. Performance of forage maize at high latitudes : plant development, agronomy and nutritive value

    Författare :Zohaib Mussadiq; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Following the development of earlier maturing hybrids the cultivation of forage maize (Zea mays L.) in Northern Europe has markedly increased in recent decades. This has raised needs for greater knowledge regarding the performance of forage maize in marginal areas, such as Sweden, under current conditions. LÄS MER

  7. 20. Exploring bis-MPA Based Dendritic Structures in Biomedicine

    Författare :Oliver Andrén; Michael Malkoch; Peter Löwenhielm; Sandra Garcia Gallego; Karen Wooley; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; Polymers; antibacterial; self-assembly; Kemi; Chemistry;

    Sammanfattning : In the last decades there has been significant advances in polymer chemistry. New coupling chemistries, polymerization techniques and accelerated approaches enable researches to push the limits of structural control. LÄS MER
