  2. 1. Down syndrome : Growth and endocrine impact

    Author : Åsa Myrelid; Jan Gustafsson; Göran Annerén; Ann-Christine Lindgren; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Down syndrome; growth; growth charts; body proportions; growth hormone; thyroid function; metabolism; body composition; cognition; motor development; Downs syndrom; tillväxt; tillväxtkurvor; kroppsproportioner; tillväxthormon; sköldkörtelfunktion; metabolism; kroppssammansättning; kognitiv förmåga; motorisk utveckling; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Abstract : Down syndrome (DS) is associated with psychomotor retardation, short stature and endocrine dysfunction. Statural growth is a well-known indicator of health. The growth in DS differs markedly from that of other children and there is a 20 cm reduction of final height as compared to target height. READ MORE

    Abstract : The mature vascular system is composed of a network of blood vessels organized into arteries, capillaries, and veins. The vessels are composed of endothelial cells surrounded by smooth muscle cells and embedded in a specialized basement membrane. READ MORE

  6. 4. Epitaxial growth of semiconductor nanowires

    Author : Ann Persson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; materialteknik; nanowires; nanostructures; growth mechanism; Materiallära; Material technology; Halvledarfysik; Semiconductory physics; nanoelectronics; Au; VSS; VLS; surface diffusion; band gap engineering; InP; ternary system; GaAs; heterostructures; InAs; CBE; epitaxy;

    Abstract : This thesis describes the results obtained from investigations carried out on epitaxially grown III-V semiconductor nanowires aimed at improving our understanding of and knowledge on the growth mechanism of nanowires. This is important to be able to control their growth, in order to make future applications possible. READ MORE

  7. 5. Nanoscale Crystal Growth: The Importance of Interfaces and Phase Boundaries Kristallväxt på Nanometer Skala: Vikten av Ytor och Gränser

    Abstract : Surfaces and interfaces have a special significance to nanotechnology because the surface/volume ratio of nanomaterials is larger than for bulk materials. Therefore, interfaces of nanomaterials are usually more important to the properties of nanomaterials than for larger scale materials. READ MORE
