  1. 1. On the Road to a Software Profession : Students’ Experiences of Concepts and Thresholds

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Boustedt; Uppsala universitet.; Uppsala universitet.; Högskolan i Gävle.; [2010]
    Keywords : Natural Sciences Computer and Information Science Computer Science; Naturvetenskap Data- och informationsvetenskap Datavetenskap datalogi ; Social Sciences Educational Sciences Didactics; Samhällsvetenskap Utbildningsvetenskap Didaktik; Datavetenskap med inriktning mot datavetenskapens didaktik; Computer Science with specialization in Computer Science Education Research; Biographies; class diagram; computer science education; computer science education research; computing concepts; concept map; content analysis; higher education; java interface; learning; object orientation; phenomenography; programming; role-play; software development; software profession; threshold concepts; variation theory;

    Abstract : Research has shown that there are gaps in knowledge between newly hired and experienced professionals and that some of these gaps are related to concepts, such as the concepts of object orientation. This problem, and the fact that most computer science majors want to work in the software industry, leads to questions regarding why these gaps exist and how students can be better prepared for their future careers.

  2. 2. Controlling Structure and Water Miscibility of Polyion - Surfactant Ion Complex Salts

    University dissertation from Physical chemistry 1 Kemicentrum Lund University

    Author : Jens Norrman; Lunds universitet.; Lund University.; [2007]
    Keywords : Fysikalisk kemi; Physical chemistry; phase diagram; cubic Pm3n; hexagonal; lamellar; self diffusion; PFG NMR; SAXS; liquid crystals; polymer; counterion; complex; polyelectrolyte; surfactant; Kemi; Chemistry;

    Abstract : The interaction between poylions and oppositely charged surfactant ions has been investigated. This has been done by using the pure complex salt (polyion + surfactant ion) as a point of departure. Different parameters of the complex salt have been varied in a systematic way and the effect on structure and water miscibility has been investigated. READ MORE

  3. 3. An Investigation of Thermogelling Aqueous Systems of Ethyl(HydroxyEthyl)Cellulose and Ionic Surfactants

    University dissertation from Department of Food Technology, P.O.Box 124, S-221 00 Lund, Sweden

    Author : Katarina Lindell; Lunds universitet.; Lund University.; [1996]
    Keywords : HS-DSC; polymer-polymer association; SANS; solubilization; dexamethasone; timolol maleate; in vitro release; thermoreversible gelation; phase diagram; cloud point; Ethyl hydroxyethyl cellulose; ionic surfactants; Livsmedelsteknik; Food and drink technology; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING;

    Abstract : Aqueous solutions of a particular type of the nonionic cellulose derivative ethyl(hydroxyethyl)cellulose (EHEC) may form thermoreversible gels in the presence of ionic surfactants. Low-viscous solutions can be transformed to clear, stiff gels as the temperature is increased. READ MORE

    Abstract : Perovskite based materials have great potentials for various energy applications and the search for new materials for uses in SOFCs has largely been concentrated to this class of compounds. In this search, we have studied perovskite phases in the system La2Co1+z(Ti1-xMgx)1-zO6, with 0  x 0.9 and z = 0.0, 0. READ MORE

  5. 5. Initiation of ventilation, surfactant treatment, and lung function after preterm birth

    University dissertation from Department of Clinical Sciences, Lund Faculty of Medicine, Lund University

    Author : Lars Björklund; Lunds universitet.; Lund University.; [2005]
    Keywords : Artificial; Respiration; Pediatrics; Pediatri; Respiratory Function Tests; Pulmonary Surfactants; Newborn; Respiratory Distress Syndrome; Infant; Premature; Animals; MEDICIN; MEDICINE;

    Abstract : The thesis investigates lung function and the effects of rescue surfactant treatment in mechanically ventilated preterm human infants with respiratory distress syndrome (RDS), and the effects of ventilation at birth on the response to surfactant supplementation in preterm lambs. To assess lung function, the author recorded static pressure-volume (P-V) curves during passive deflation from total lung capacity (TLC) to ambient pressure and measured end-expiratory lung volume (FRC) during mechanical ventilation by tracer gas washout.
