  1. 6. New Nanopores for Combined Plasmonic and Electrical Sensing

    Författare :Kunli Xiong; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Colloidal lithography; Plasmonic; Electrical technology; Thermal Energy.; Surface; Biosensor;

    Sammanfattning : In this thesis, several kinds of artificial plasmonic biosensors are introduced. They havedifferent nanostructures which are nanoholes, nanowells and nanopores. The fabricationtechnologies are introduced. All these nanostructures are fabricated based on colloidallithography technology and following by several special steps. LÄS MER

  3. 7. Klassrumsbedömning i matematik på gymnasieskolans nivå

    Författare :Semir Becevic; Claes Ericsson; Pernilla Nilsson; Jesper Boesen; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : Klassrumsbedömning i matematik på gymnasienivå är en licentiatstudie med en intention att närma sig, fånga upp samt förstå och tolka lärares ageranden, tankar, upplevelser och reflektioner inom och om bedömningen i matematik i gymnasiet. En annan avsikt är delvis att fylla i luckan mellan det målrelaterade kursbedömningssystemet och det praktiska fältet med en kvalitativ forskningsstudie om lärarerfarenheter från gymnasiets matematikkurser.

  4. 8. Regulation of chloroplast development during the greening process

    Författare :Yan Ji; Åsa Strand; Eevi Rintamäki; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; light response; anterograde signalling; plastid transcription; chloroplast development; photosynthesis; bZIP; PEP complex; de-etiolation; molekylärbiologi; Molecular Biology;

    Sammanfattning : Upon light exposure, the expression of one-third of the nuclear-encoded genes is changing, including genes encoding many chloroplast-targeted proteins responsible for the initiation of plastid transcription and the establishment of photosynthesis. The control of the nuclear-encoded genes involved in the development of chloroplast is referred to as anterograde signalling. LÄS MER

  5. 9. Chemical reactivities as a mirror of environmental transformations - method development and assessment of some selected organohalogens

    Författare :Lisa Granelli; Åke Bergman; Johan Eriksson; Roland Kallenborn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Sammanfattning : The assement of chemical persistence is an important part of legislative protection of the environment and human health. Of the vast number of chemicals on the market today few have been properly assessed. LÄS MER

  7. 10. Closing the Gap : How an Adaptive Behavioral Based Program on a Tablet Can Help Low Performing Children Catch Up in Math: a Randomized Placebo Controlled Study

    Författare :Martin Hassler Hallstedt; Ata Ghaderi; Tomas Furmark; Nancy Jordan; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; intervention; mathematics; tablet; fluency; short and long-term effects; educational technology; Psychology; Psykologi;

    Sammanfattning : Early mathematic skills have a substantial impact on later school achievement. Children with poor school achievement are at risk for adverse consequences later in life. Math competencies also have consequences for the economy at large because societies are becoming increasingly dependent on skill sets including mathematics. LÄS MER
