We investigate the phase transitions in InAs/GaSb quantum wells sandwiched between two wide-gap AlSb barrier layers under an external electric field perpendicular to interfaces. The Schrodinger and the Poisson equations are solved self-consistently to derive the subband dispersions, the potential profile, the electron charge distribution in the InAs layer, and the hole charge distribution in the G

Syftet med detta forskningsprojekt är att undersöka hur ett antal väl dokumenterade experimenthus har fungerat under en tioårsperiod. Undersökningen jämför i första hand uppgifter om energianvändning och de driftfrågor som hör till energianvändningen. Vidare har de boendes upplevda inomhusklimat studerats för att kunna se om, och i så fall hur, experimenthusens låga energianvändning har påverkat d

Essä om Ian Flemings författarskap med fokus på James Bond-serien och de första filmatiseringarna.

We have examined long-term growth-factor expanded human neural progenitors following transplantation into the adult rat brain. Cells, obtained from the forebrain of a 9-week old fetus, propagated in the presence of epidermal growth factor, basic fibroblast growth factor, and leukemia inhibitory factor were transplanted into the striatum, subventricular zone (SVZ), and hippocampus. At 14 weeks, imp

Popular Abstract in Swedish ”Luffarturismen” har blivit en populär form av resande. Många svenskar för under en tid - ibland flera månader eller år - en vagabonderande tillvaro på platser långt hemifrån. Resan blir en parentes i vardagen - en extraordinär sfär fylld av förväntningar på äventyret och den äkta upplevelsen. Vad har resenären för bild av det ”Långtbortistan” hon lockas av, och hur skThis dissertation, The Attraction of the Extraordinary - Images and Experiences Among Backpacker Tourists, is a study based on informal interviews with predominantly Swedish independent travellers, as well as observations and documentary analysis of the backpacker subculture. Backpacking is a type of tourism which has been gradually institutionalized. Through the institutionalization of the backpa

Relativistic fragmentation of Pb-208 has been used to produce excited states in neutron-rich nuclei with N approximate to 126. Spectroscopic information for a range of nuclei has been obtained through observing delayed gamma-ray emissions from isomeric states. Preliminary results for Pt-203,Pt-204 nuclei are presented. For the first time, excited states have been observed in Pt-203 and Pt-204. The

The role of the carbohydrates for the structure and functions of the plasma and tissue protein alpha1-microglobulin (alpha1m) was investigated by deletion of the sites for N-glycosylation by site-directed mutagenesis (N17,96-->Q). The mutated cDNA was expressed in a baculovirus-insect cell system resulting in a nonglycosylated protein. The biochemical properties of N17,96Q-alpha1m were compared to

BACKGROUND. Intrauterine growth retardation is one of the major causes of perinatal mortality and morbidity. To date, there are no reliable methods to detect brain damage in these patients. METHODS. We conducted a case-control study in tertiary NICUs from December 2001 to December 2003 with 42 intrauterine growth retardation infants and 84 controls. Routine laboratory variables, neurologic outcome

Annotated translation (with introduction and commentary) of Mao Zedong's three speeches at the Moscow Meeting of Representatives of Communist and Workers' Parties in November 1957.

The development of mature B lymphoid cells involves a highly orchestrated regulation of stage- and lineage-specific genes. In this study, we report an analysis of the human surrogate L chain VpreB promoter. The promoter has an overall homology of 56% to the mouse counterpart and displays a preB cell-restricted activity in transient transfections in cell lines. The promoter harbors three independen

Based upon earlier experimental work by our group, we have started a human immuno-gene therapy study. The goal is to study the effects of immunisation with autologous tumour cells expressing gene sequences for human interferon-gamma For more than two decades we have sought for efficient treatment against malignant gliomas. Our most successful treatment in the animal models is immuno-gene therapy w

BACKGROUND: Neonatal screening for alpha(1)-antitrypsin (AAT) deficiency was undertaken in Sweden between 1972 and 1974 when 129 infants with severe AAT deficiency (phenotype PiZ) were identified. The cohort has been followed up prospectively. METHODS: 124 PiZ subjects, still alive and still living in Sweden, were invited to a follow up examination at about 22 years of age. The check up included a
