  1. 1. Selective conversion of alcohols to aldehydes over metal oxide catalysts

    Författare :Mariano Massa; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. LÄS MER

  3. 2. Epigenetic Regulation and Reprogramming of the H19 Imprinting Control Region

    Författare :Piero Mariano; Rolf Ohlsson; Karl Ekwall; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Imprinting; chromatin; H19; Igf2; CTCF; Insulator; methylation; Boris; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : The development of a new individual from the fertilized oocyte can ultimately be seen as the consequence of the establishment and maintenance of specific patterns of gene expression. Although regulation of gene activity occurs at different levels, cellular specialization and differentiation are the results of developmental cues that essentially take place at the transcriptional level.

  4. 3. Intimate partner violence in Nicaragua : studies on ending abuse, child growth, and contraception

    Författare :Virgilio Mariano Salazar Torres; Ulf Högberg; Ann Öhman; Eliette Valladares; Rachel Jewkes; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intimate partner violence; IPV; child growth; contraception; pregnancy; Nicaragua; ending abuse; Public health science; Folkhälsovetenskap; folkhälsa; Public health;

    Sammanfattning : Background: Intimate partner violence (IPV) is a pervasive, worldwide public health problem and one of the most common violations of human rights. The aim of this thesis were twofold: (i) to study the process and factors related to ending of IPV of Nicaraguan women and (ii) to examine to what extent IPV exposure is associated with the child linear growth and women’s contraceptive use after pregnancy.

  5. 4. Revising Business Model Innovation: Towards a value process framework for AI-based Offerings

    Författare :Girish Agarwal; Mats Magnusson; Mariano Corso; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digitalization; Value; Artificial Intelligence; Business Model Innovation; Machine Design; Maskinkonstruktion;

    Sammanfattning : Advances over the last few decades in digital technologies in general and artificial intelligence (AI) technology in particular have transformed many industries. There are many successful AI use cases in industry. LÄS MER

  7. 5. Solution Chemistry and Morphological Properties for Organic Solar Cells : Exploring Alternative Solvents Using Microgravity and Modelling as Tools

    Författare :Ishita Jalan; Jan van Stam; Patricia Saenz Mendez; Stela Andrea Muntean; Mariano Campoy-Quiles; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solution chemistry; green solvents; microgravity; OPV; HSP; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Sammanfattning : Organic photovoltaics (OPVs) have the advantage of the accessibility of energy for all, due to facile and low-cost processing, with its low energy payback time compared to other technologies, therefore promising applications. Research and development have led to power conversion efficiencies of nearly 20% and now catching up to their inorganic counterparts. LÄS MER
