  1. 1. Development of rotation electron diffraction as a fully automated and accurate method for structure determination

    Författare :Bin Wang; Xiaodong Zou; Andy Stewart; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; structure determination; structure refinement; metal-organic framework; guest molecules; software development; automation; hierarchical cluster analyses; high-throughput data processing; data merging; frame orientations; least-squares optimization; data processing; TEM goniometer; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Over the past decade, electron diffraction methods have aroused more and more interest for micro-crystal structure determination. Compared to traditional X-ray diffraction, electron diffraction breaks the size limitation of the crystals studied, but at the same time it also suffers from much stronger dynamical effects. LÄS MER

  3. 2. Characteristics of Self-Injury in Young Adolescents : Findings from Cross-Sectional and Longitudinal Studies in Swedish Schools

    Författare :Jonas Bjärehed; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-suicidal self-injury; NSSI; Deliberate self-harm; DSH; Adolescents; cluster analysis;

    Sammanfattning : Self-injury in adolescents (e.g. when individuals cut, burn, hit or otherwise deliberately cause themselves direct injury), has gained recognition as a potentially important mental health problem during the past decade. Relatively little has been known about the scope and characteristics of this behavior in Swedish adolescents. LÄS MER

  4. 3. Empirical Bayes Methods for DNA Microarray Data

    Författare :Ingrid Lönnstedt; Allan Gut; Tom Britton; Mette Langaas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; two-channel microarrays; differential expression; replication; empirical Bayes; factorial design; interaction; time trends; hierarchical Bayes; MCMC simulations; ANOVA; F-statistics; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Sammanfattning : cDNA microarrays is one of the first high-throughput gene expression technologies that has emerged within molecular biology for the purpose of functional genomics. cDNA microarrays compare the gene expression levels between cell samples, for thousands of genes simultaneously.

  5. 4. Functional Inference from Orthology and Domain Architecture

    Författare :Mateusz Kaduk; Erik Sonnhammer; Erich Bornberg-Bauer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Orthology; Functional coupling networks; Association networks; Hierarchical groups of orthologs; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

    Sammanfattning : Proteins are the basic building blocks of all living organisms. They play a central role in determining the structure of living beings and are required for essential chemical reactions. One of the main challenges in bioinformatics is to characterize the function of all proteins. LÄS MER

  7. 5. Directed Evolution of Glutathione Transferases Guided by Multivariate Data Analysis

    Författare :Sanela Kurtovic; Bengt Mannervik; Ulf Hellman; Denis Pompon; Uppsala universitet; []
    Nyckelord :Biochemistry; DNA shuffling; substrate selectivity; mutant library; glutathione transferase; multivariate data analysis; prodrug; Biokemi;

    Sammanfattning : Evolution of enzymes with novel functional properties has gained much attention in recent years. Naturally evolved enzymes are adapted to work in living cells under physiological conditions, circumstances that are not always available for industrial processes calling for novel and better catalysts.
