  3. 12. Green Deserts or New Opportunities? : Competing and complementary views on the soybean expansion in Uruguay, 2002-2013

    Författare :Matilda Baraibar; Ulf Jonsson; Ronny Pettersson; Cristóbal Kay; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Uruguay; Soybean expansion; Discourse analysis; Agrarian change; Development perspectives; Agrifood globalization; agro-ecology; public regulation; pro-market; ekonomisk historia; Economic History;

    Sammanfattning : In just over a decade, soybean production in Uruguay emerged from almost non-existence to second most important export product. The extraordinary rapid soybean expansion is often referred to as representing changes that go far beyond the mere substitution of one agrarian activity for another, but evolved into a broad societal concern.

  4. 13. Molecular Screening for Target Discovery in Cancer

    Författare :Mårten Fryknäs; Anders Isaksson; Ulf Pettersson; Hugh Salter; Uppsala universitet; []
    Nyckelord :Genetics; Cancer; Drug resistance; Microarray; High-throughput screening; Genetik;

    Sammanfattning : Cancer is one of the major causes of death in the western world. Resistance to anti-cancer drugs and diagnostic difficulties are major obstacles to successful treatment. LÄS MER

  5. 14. Use of local electrochemical techniques for corrosion studies of stainless steels

    Författare :Nuria Fuertes; Rachel Pettersson; Mari Sparr; Ulf Kivisäkk; Yolanda Hedberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; passive film; thermal oxides; work function; pickling; SKPFM; SVET; XPS; AES; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The excellent corrosion resistance of stainless steels arises from the presence of a passive film on its surface. Above 10.5wt% Cr a chromium oxide of 1-3 nm is formed on the surface of the metal that in case of damage will reform and hinder further dissolution of the metal. LÄS MER

  7. 15. Global Profiling of Host Cell Gene Expression During Adenovirus Infection

    Författare :Fredrik Granberg; Hongxing Zhao; Ulf Pettersson; Richard Roberts; Uppsala universitet; []
    Nyckelord :Genetic engineering; Adenovirus; Microarray; Gene expression; Host-virus interaction; Genteknik;

    Sammanfattning : To investigate mechanisms involved in virus-host interactions, global changes in host gene expression were examined during infection with adenovirus type 2 (Ad2) using cDNA microarray technology. In paper I and II, transcriptional changes in HeLa cells were investigated during the early and late phase of infection, respectively. LÄS MER
