  4. 2. Effects of Food Supplementation and Psychosocial Stimulation on Growth and Development of Severely Malnourished Children : Intervention Studies in Bangladesh

    Author : Baitun Nahar; Lars-Åke Persson; SM Grantham-McGregor; Tahmeed Ahmed; Kim F Michaelsen; Uppsala universitet; []
    Keywords : Psychosocial stimulation; food supplementation; HOME; child-rearing practices; maternal depressive symptoms; severe malnutrition; Bangladesh; International Health; Internationell hälsa;

    Abstract : Early childhood malnutrition is a global public health problem with serious short- and long-term consequences. The aim of this thesis is to evaluate the effects of psychosocial stimulation (PS) with or without food supplementation (FS) on growth and development of severely malnourished children, quality of home environment, mother’s child-rearing practices and depressive symptoms.

  5. 3. Spectral Analysis of Neutron Capture Elements in the Laboratory and Stars

    Author : Martin Lundqvist; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmic chemistry; Astronomy; space research; Atom- och molekylärfysik; Atomic and molecular physics; Astronomi; Sm; Hf; Os; Ir; Neutron capture processes; rymdvetenskap; kosmisk kemi; cool stars; Spectroscopy; atomic data;

    Abstract : The pedigree of the elements heavier than iron is a vital question in the history and evolution of our galaxy. The elements up to and including those of the iron group are produced mainly through fusion processes within stars, giving the stars their energy. READ MORE

  6. 4. Quasicrystal Approximants in the RE-Au-SM systems (RE = Gd, Tb, Ho, Yb; SM = Si, Ge) : Syntheses, structures and properties

    Author : Girma Hailu Gebresenbut; Cesar Pay Gómez; Martin Sahlberg; Torbjörn Gustafsson; Alan I. Goldman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quasicrystal approximant; structure; physical property; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this study, new Tsai-type 1/1 quasicrystal approximants (ACs) in the RE-Au-SM systems (RE = Gd, Tb, Ho, Yb; SM = Si, Ge) were synthesized using high temperature synthesis techniques such as self-flux, arc-melting-annealing and novel arc-melting-self-flux methods. The syntheses not only provided appropriate samples for the intended structural and physical property measurements but could also be adapted to other systems, especially where crystal growth is a challenge.

  7. 5. Syntheses, structure determination, magnetic and thermoelectric properties of quasicrystal approximants in RE-Au-SM systems (RE = Gd, Tb and Yb and SM = Si, Ge)

    Author : Girma Hailu Gebresenbut; Cesar Gomez; Martin Sahlberg; Torbjörn Gustafsson; Lars Eriksson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quasicrystals; quasicrystal approximants; thermoelectric properties; magnetic properties; Materialvetenskap; Materials Science;

    Abstract : In this study, new compositions of Tsai-type 1/1 quasicrystal approximants Gd(14)Au(70)Si(16), Gd(14)Au(67)Ge(19), Tb(14)Au(70)Si(16) and Yb(16)Au(65)Ge(19)are synthesized using both self-flux and arc-melting-annealing techniques. Both syntheses routes resulted single phase samples. READ MORE
