  3. 3. Roles of LESIONS SIMULATING DISEASE1 and Salicylic Acid in Acclimation of Plants to Environmental Cues : Redox Homeostasis and physiological processes underlying plants responses to biotic and abiotic challenges

    Författare :Alfonso Mateo; Stanislaw Karpinski; Philip M. Mullineaux; John F. Allen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LSD1; Photooxidative stress; Reactive oxygen species; Light acclimation; Photorespiration; Salicylic acid; Plant physiology; Växtfysiologi;

    Sammanfattning : In the natural environment plants are confronted to a multitude of biotic and abiotic stress factors that must be perceived, transduced, integrated and signaled in order to achieve a successful acclimation that will secure survival and reproduction. Plants have to deal with excess excitation energy (EEE) when the amount of absorbed light energy is exceeding that needed for photosynthetic CO2 assimilation. LÄS MER

  4. 4. Equilibrium studies of ternary aluminium(III) hydroxo complexes with ligands related to conditions in natural waters

    Författare :Lars-Olof Öhman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aqueous solution; binary and ternary hydroxo complexes of Al3 ; carbonic acid; citric acid; phenolic ligands; emf-titrations; equilibrium analysis; model calculations towards natural waters;

    Sammanfattning : The thesis is a summary and discussion of eight papers. During the last decades, precipitation has become increasingly acidic due to the extensive use of fossil fuels. In areas of poorly buffered bedrocks, e.g. LÄS MER

  5. 5. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties

    Författare :Sung-Woo Cho; Mikael Hedenqvist; Amar K. Mohanty; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; wheat gluten; solution casting; compression molding; extrusion; injection molding; aging; migration; opacity; heat sealability; hemp fiber; laminate; polylactic acid; clay; nanocomposites.; Other chemical engineering; Övrig kemiteknik;

    Sammanfattning : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.
