    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Internet; net cultures; children; digital native; online threats; counter-strategies; online interviews; online ethics; Pedgogical work; Pedagogiskt arbete;

    Abstract : This thesis deals with the following questions: What do children find negative on the Internet? What counter strategies do they use? How have they developed these strategies? The method used is one-to-one online interviews and the analyses are qualitative in nature. The sample is children in grade 6 of the Swedish compulsory school, aged between 11 and 13. READ MORE

  4. 2. Engineering of Native Cellulose Structure for Pharmaceutical Applications : Influence of Cellulose Crystallinity Index, Surface Area and Pore Volume on Sorption Phenomena

    Author : Albert Mihranyan; Ragnar Ek; Maria Strømme; Hans Leuenberger; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; microcrystalline cellulose; Cladophora sp. algae; crystallinity index; surface area and pore volume; fractals; stability; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : Cellulose powders from various sources were manufactured and characterized to investigate the influence of their crystallinity index, surface area, and pore volume on sorption phenomena and the relevant pharmaceutical functionality. The influence of the cellulose crystallinity index on moisture sorption was important at low and intermediate relative humidities. READ MORE

  5. 3. Physiological Studies of Native and Stem Cell-Derived Islets

    Author : Daniel Norman; Per-Ola Carlsson; Daniel Espes; Helge Ræder; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irisin; CART; Islet blood flow; Islets of Langerhans; Stem cell-derived islets; Fysiologi; Physiology; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : In type 1 and type 2 diabetes, the β-cells of the islets of Langerhans are either destroyed by the immune system or stressed due to peripheral insulin resistance. To improve the life of patients with these diseases, new treatments are needed. READ MORE

  6. 4. Defects and Impurities in CdTe : An ab Initio Study

    Author : Anna Lindström; Mattias Klintenerg; Susanne Mirbt; Biplab Sanyal; Peter Zahn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Native defects; Compensation mechanisms; Semiconductor doping; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this thesis defects and impurities in CdTe have been studied with ab initio methods. CdTe is a II-VI semiconductor with many important applications such as γ- and X-ray detectors, solar cells and medical imaging. READ MORE

  7. 5. Efficient and Flexible Characterization of Data Locality through Native Execution Sampling

    Author : Erik Berg; Erik Hagersten; Mark D. Hill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : Data locality is central to modern computer designs. The widening gap between processor speed and memory latency has introduced the need for a deep hierarchy of caches. Thus, the performance of an application is to a large extent dependent on the amount of data locality the caches can exploit. READ MORE
