  2. 1. Study of Halo Nuclei Breakup on Light Targets at Intermediate and High Energies

    Author : Ioulia Parfenova; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 6He; 15C; cross sections; 8B; longitudinal momentum distributions; D; radioactive beams; halo nucleus; nuclear breakup reactions; 11Be;

    Abstract : The study of exotic nuclei is one of the most important topics in modern nuclear physics. It allows general understanding of the structure and nature of light nuclear systems in the vicinity of the driplines. READ MORE

  4. 2. Probing the Drip-Lines through Momentum Distributions

    Author : Martin Smedberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; momentum distributions; drip-line; diffraction; 17C; 119C; core shadowing; 6He; neutron stripping; radioactive beams; break-up; intermediate resonance; neutron halo; 8He; 8B; absorption; reaction mechanism;

    Abstract : About a decade ago it was found that nuclei in the vicinity of the neutron drip-line under certain circumstances develop very extended valence neutron distributions, a phenomenon today known as halo states. The recent development of radioactive nuclear beams has provided us with a perfect tool for investigating these particular nuclei. READ MORE

  5. 3. Hypothyroidism and Pregnancy

    Author : Michaela Granfors; Anna-Karin Wikström; Inger Sundström-Poromaa; Helena Åkerud; Ulla Feldt-Rasmussen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phosphodiesterase 8B; recurrent miscarriage; single nucleotide polymorphism; thyroid; guidelines; hypothyroidism; pregnancy; survey; thyroid testing; screening; iodine; iodine deficiency; median urinary iodine concentration; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Hypothyroidism is a common endocrine disorder affecting women of reproductive age. On a global level, iodine deficiency is still the most common cause of hypothyroidism. Also genetic variations, in particular SNP rs4704397 in the PDE8B gene, are responsible for a significant proportion of TSH variations. READ MORE

  6. 4. Fibroblast growth factor-8 regulation of breast cancer cell growth

    Author : Emeli Nilsson; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Expression of fibroblast growth factor-8 (FGF-8) is increased in a large number of breast cancers. In in vitro and in vivo breast cancer models FGF-8 promotes growth, invasion and angiogenesis. READ MORE

  7. 5. Effective Field Theory and One-proton Halo Nuclei

    Author : EMIL RYBERG; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radiative capture; halo nuclei; effective field theory; nuclear physics; charge radius;

    Abstract : In this thesis we present formalism for treating one-proton halo nuclei in effective field theory. Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as a structureless, effective degree-of-freedom. READ MORE
