  1. 1. Elevers interaktiva lärande vid problemlösning i grupp : En processtudie

    Författare :Anders Jakobsson; Pedagogik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social constructivistic theory; science; problem solving in groups; learning attitudes; greenhouse effect; cognitive and knowledge development; collaboration; socio-cultural theory.; Pedagogy and didactics; Pedagogik; didaktik; pedagogisk metodik;

    Sammanfattning : This study gives an account of a teaching situation in the eighth grade with 20 student's aged 14-15. The students have worked with a scientific problem focussed on the greenhouse effect and the earth's global warming, based on a problem solving and information seeking way of working in groups.

  3. 2. On PLL Modeling and Design in Nanometer‐Scale CMOS

    Författare :Anders Jakobsson; Shaofang Gong; Adriana Serban; Hannu Tenhunen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-locked loop; Frequency synthesizer; Calibration; Modelling; Quantized-state system; Phase interpolator; Sub-sampling PLL;

    Sammanfattning : Integrated circuits play a vital role in our everyday lives, from wireless gadgets and multimedia players to sensors and processors that control vital infrastructure. Since most electronic circuits need a clean, stable clock or carrier to function, one of the most important components of integrated circuits is the phase-locked loop. LÄS MER

  4. 3. Elovl3 and very long chain fatty acids; role in metabolism

    Författare :Andreas Jakobsson; Anders Jacobsson; James Ntambi; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fatty acids metabolism elongation; Physiology; Fysiologi;

    Sammanfattning : Fatty acids (FA) are important in several aspects of cellular function, for example as structural molecules and metabolic substrates. The bulk of FA up to 16 carbons (palmitic acid) in length are synthesised by a cytosolic enzyme complex called fatty acid synthase (FAS), while FA can be further elongated into very long-chain fatty acids (VLCFA) by membrane-bound enzymes in the endoplasmatic reticulum (ER).

  7. 5. Archaeological Genetics - Approaching Human History through DNA Analysis

    Författare :Evangelia Daskalaki; Anders Götherström; Mattias Jakobsson; Walther Parson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ancient DNA; pyrosequencing; molecular genetics; aDNA; neolithization; evolutionary genetics; mtDNA; viking age; archaeological genetics; genetik; evolutionsgenetik; naturvetenskap; neolitisering; vikingatid; arkeologisk genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : There are a variety of archaeological questions, which are difficult to assess by traditional archaeological methods. Similarly, there are genetic and population genetic questions about human evolution and migration that are difficult to assess by studying modern day genetic variation. LÄS MER
