  1. 1. Kraft, form, transformationer : Om kinestetisk musikalitet och kroppsvärldande i pojkars krigslek

    Författare :Ebba Theorell; Inger Eriksson; Ulrika von Schantz; Cecilia Roos; Elin Eriksen Ødegaard; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; War play; improvisation; proprioception; perception; aesthetics; kinestesia; space; body-subject; transduction; transformation; force; form; time; becoming; attention; sensation; the thinking body and body-worlding; ämnesdidaktik med inriktning mot de estetiska ämnenas didaktik; Teaching and Learning with Specialisation in the Arts Education;

    Sammanfattning : War play has generally been studied with violence as a central perspective, investigating its impact on children’s aggression, both in a positive and negative sense. Some research results have claimed that war play can contribute to normalising or even encouraging violent behavior amongst children, while other results have claimed that children can develop important physical, cognitive or social skills through war play.

  3. 2. Surface interactions and adsorbate structures : An atomic force microscopy study

    Författare :Goran Bogdanovic; KTH; []
    Nyckelord :atomic force microscope; AFM; cantilever calibration; colloidal probe; surface force; force curve; friciton; hydrophobic; adhesion; roughness; multilayer; silica; cellulose; cationic polyelectrolyte; MAPTAC;

    Sammanfattning : Atomic force microscopy, AFM, was used for studying somecurrent topics in the field of surface and colloid science. Themain topics addressed in this thesis were: the nature of thelong-range attraction between hydrophobic surfaces; slidingfriction behavior for microscopic contacts; and interfacialstructuring of polyelectrolyte-nanoparticle multilayerfilms.

  4. 3. Leibniz on Agency and Force

    Författare :Peter Myrdal; Lilli Alanen; Pauliina Remes; John Carriero; Michael Della Rocca; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Leibniz; Gottfried Wilhelm; 1646-1716; Early Modern Philosophy; Agency; Force; Final causes; Theoretical Philosophy; Teoretisk filosofi;

    Sammanfattning : This is a study of Leibniz’s theory of agency – his theory of the nature of causal powers and agents. Leibniz develops his view against the background of an Aristotelian conception of agency. The latter was rejected by many early modern philosophers in the wake of the mechanist conception of the natural world. LÄS MER

  5. 4. Reconstructing force from harmonic motion

    Författare :Daniel Platz; David B. Haviland; John E. Sader; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; oscillator; force spectroscopy; atomic force microscopy; intermodulation; multifrequency; inverse problem; high quality factor;

    Sammanfattning : High-quality factor oscillators are often used in measurements of verysmall force since they exhibit an enhanced sensitivity in the narrow frequencyband around resonance. Forces containing frequencies outside this frequencyband are often not detectable and the total force acting on the oscillatorremains unknown. LÄS MER

  7. 5. Force measurements using scanning probe microscopy : Applications to advanced powder processing

    Författare :Anders Meurk; KTH; []
    Nyckelord :atomic force microscope; AFM; SPM; van der Waals interaction; DLVO-theory; surface forces; colloidal probe; force curve; friction; adhesion; stick-slip; cantilever; calibration; spring constant; silicon nitride; iron; silica;

    Sammanfattning : The object of this thesis is to apply scanning probemicroscopy (SPM) to the field of advanced powder processing.Measurement of interparticle surface forces at conditionsrelevant to ceramic processing has been performed together withthorough studies of powder friction. LÄS MER
