  1. 36. Modeling urban energy flows at macro and district levels : towards a sustainable urban metabolism

    Författare :Aumnad Phdungsilp; Ivo Martinac; Kevin Bennett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The urban sustainability is a growing importance in the built environment research. Urban areas play a key role in planning for sustainable city development. Urbanization has implications for future energy systems and energy-related emissions. LÄS MER

  4. 38. From green to yellow : a leaf story

    Författare :Olivier Keech; Per Gardeström; Pierre Dizengremel; Lee Sweetlove; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplasts; cytoskeleton; darkness; metabolism; microscopy; mitochondria; microtubules; senescence; system redox; Plant physiology; Växtfysiologi;

    Sammanfattning : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. LÄS MER

  5. 39. Diet and gastrointestinal cancer : one-carbon metabolism and other aspects

    Författare :Susanna C Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Diet has been hypothesized to play a major role in the etiology of gastrointestinal cancer, but the specific dietary factors involved remain unclear. The aims of this thesis were: to examine the associations of dietary magnesium and vitamin B6 intakes with risk of colorectal cancer in the Swedish Mammography Cohort (SMC); to evaluate the relation between folate intake and risk of pancreatic cancer in the SMC and the Cohort of Swedish Men (COSM); to use metaanalysis to summarize the evidence from published studies of the associations of folate intake and polymorphisms in the gene encoding 5,10-methylenetetrahydrofolate reductase (MTHFR C677T and A1298C), a central enzyme in one-carbon metabolism, with risk of esophageal, gastric, pancreatic, and colorectal cancer; and to perform a meta-analysis of epidemiologic studies of the relationship between processed meat consumption and risk of gastric cancer.

  7. 40. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere

    Författare :Xiaofen Wu; Mark Dopson; Ricardo Amils; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular phylogeny; acid sulfate soils; metal; acidophiles; deep biosphere; oligotrophy; biofilm formation; metagenome; binning; metabolism; Mikrobiologi; Microbiology;

    Sammanfattning : This thesis describes the use of different DNA sequencing technologies to investigate the structure and function of microbial communities in two extreme environments, boreal acid sulfate soil and the terrestrial deep biosphere.The first of the two investigated environments was soils containing un-oxidized metal sulfides that are termed ‘potential acid sulfate soil’ (PASS) materials.
