    Sammanfattning : 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. LÄS MER

    Sammanfattning : 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. LÄS MER
