  2. 21. Oxidation induced failure of superalloys: High temperature crack growth and oxide scale properties

    Author : Anand Harihara Subramonia Iyer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micromechanical testing; crack growth; Nickel superalloys; scanning electron microscopy; focused ion beam microscopy;

    Abstract : Gas turbine materials are designed to work in extreme environments in high temperature with an oxidising environment and variable mechanical loading. The study of high temperature fatigue properties of these materials is therefore important. READ MORE

  4. 22. Molten carbonate fuel cells for electrolysis

    Author : Lan Hu; Carina Lagergren; Göran Lindbergh; Søren Højgaard Jensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Durability; electrode kinetics; gas phase mass transport; molten carbonate electrolysis cell; molten carbonate fuel cell; performance; reversible.; Chemical Engineering; Kemiteknik;

    Abstract : The molten carbonate fuel cell has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis, it provides a promising option for producing fuel gases such as hydrogen and syngas. The cell can thereby operate reversibly as a dual energy converter for electricity generation and fuel gas production. READ MORE

  5. 23. Gene Regulation and Epigenetic Mechanisms in the Parasite Trypanosoma cruzi

    Author : Patricia Respuela; Lena Åslund; George A.M. Cross; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; Molekylärbiologi;

    Abstract : Trypanosomes are unicellular protozoan parasites responsible for several human diseases that affect millions of people and cause thousands of casualties every year. They also represent a primitive eukaryotic model system harboring unique processes and basic regulatory mechanisms such as RNA-editing, polycistronic transcription and trans-splicing, first described in these organisms.

  6. 24. Long-range Control of Gene Expression by Imprinting Control Regions During Development and Neoplasia

    Author : Noopur Thakur; Chandrasekhar Kanduri; Thomas Ekstrom; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Genomic imprinting; Imprinting control region; Antisense RNA; de novo methylation; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Genomic imprinting is an epigenetic phenomenon by which a subset of genes is expressed in a parent of origin specific manner. Most of the imprinted genes are located in clusters. Genetic evidences suggest that genes in imprinted clusters are regulated by Imprinting Control Regions (ICRs). READ MORE

  7. 25. State-Oriented Business Process Modeling : Principles, Theory and Practice

    Author : Ilia Bider; KTH; []
    Keywords : business process; dynamical system; formal semantics; persistent action; law-based programming; business analysis; business modeling; object-oriented modeling; conceptual modeling; workflow;

    Abstract : In the last 50 years, a considerable amount of research workhas been completed in the mathematical system theory and theoryof control. Implementation of the results from this researchinto practice has drastically decreased the production costs.Most production processes are highly automated, and the use ofrobots in industry is growing.
