  1. 1. Exploring the complexity of functional hiv-1 specific t-cell responses and global virus-host genetic variability

    Författare :Carina Pérez; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : HIV has become one of the biggest health problems up to date. After 30 years of tremendous effort, the development of an HIV vaccine is still far from achieved. One of the main issues is the high mutation rate of the virus which results in the selection of mutated variants. LÄS MER

  3. 2. The Challenges of Analyzing the Molecular Properties of Starch

    Författare :Daysi Pérez; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amaranthus caudatus; Chenopodium quinoa; Chenopodium pallidicaule; Canna indica; Lepidium meyenii; Xanthosoma sagittifolium; Manihot esculenta; starch; amylose; amylopectin; field-flow fractionation; size distribution; dissolution;

    Sammanfattning : Both the nutritional and functional properties of starch are directly influenced by the molecular structure of its polymers: amylose and amylopectin. It is therefore important to have reproducible methods for quantifying the molecular size. LÄS MER

  4. 3. Mellan det förflutna och framtiden : Den sandinistiska revolutionen i Nicaragua

    Författare :Enrique Pérez; Socialantropologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nicaragua; revolution; tradition; development; democracy; cooperation; popular participation; local development; Sandinismo; Cultural anthropology; applied anthropology; ethnology; Kulturantropologi; etnologi;

  5. 4. Deformation and failure of hard rock under laboratory and field conditions

    Författare :Kelvis Pérez; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : The understanding of the fracture mechanisms and failure processes of the rock is an important requirement for the design of mining excavations and civil engineering constructions. The fracture process is necessary for the excavation and fragmentation of rock, but fracture of rock must be avoided and controlled to preserve the integrity of the construction. LÄS MER

  7. 5. A teacher-centred design system to integrate digital technologies in secondary mathematics classrooms

    Författare :Miguel Perez; Marianna Bosch; John Monaghan; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Design; digital technologies; praxeology; teachers; professional development; inquiry systems; agile educational design; Mathematical Education; Matematikdidaktik;

    Sammanfattning : Despite efforts made by teachers and researchers, studies show that digital technologies have not improved conditions for teaching and learning mathematics to the degree expected by stakeholders inside as well as outside the school system.In this research, the problem of the integration of digital technologies is addressed through the perspective of design.
