We have studied the atomic scale structure of molecular beam epitaxy grown Ga1-xMnxAs compounds with various Mn concentrations by cross-sectional scanning tunneling microscopy and first principles calculations. Only bright protrusions close to the top layer As atoms are directly correlated with the bulk Mn concentration. Atomically resolved filled and empty states images of this defect are compare

Sulfonylureas and glinides have similar mechanisms of action but differ in receptor affinity and binding sites and in absorption and elimination rates. This promotes differences in potency, rate of onset, and duration of action. While prominent in single-dose studies, these differences have less importance during long-term sulfonylurea treatment: at ordinary dosages, rapid- and short-acting (glipi

Rapid heat transfer methods can be used to speed up the baking, process and create new product properties. This study investigates the effect of air jet impingement and infrared radiation (alone or in combination) on crust formation of par-baked baguettes during post-baking. The parameters investigated are crust color; crust thickness, total water loss, and heating time. The results show that infr
Aim: To describe the prevalence of myelomeningocele (MMC) and the medical needs of adolescents, 15-18 years, with MMC in Sweden, at a time when they are on the threshold of adulthood, leaving paediatrics. Methods: In a retrospective study, we identified all adolescents with MMC, born during 1986-1989 and living in Sweden on July 1, 2004. An inventory was agreed upon with questions concerning their
The gas-to-aqueous solution shifts of the O-17 and C-13 NMR isotropic shielding constants for the carbonyl chromophore in formaldehyde and acetone are investigated. For the condensed-phase problem, we use the hybrid density functional theory/molecular mechanics approach in combination with a statistical averaging over an appropriate number of solute-solvent configurations extracted from classical
Studies report that urticarial dermographism is exacerbated by "life events" and emotions. The aim of this study was to determine what aspects of life quality are affected by symptomatic dermographism and whether acute stress is a potential triggering factor. A total of 21 adult patients with urticarial dermographism completed a questionnaire on symptoms and quality of life. Twelve patients agreed
BACKGROUND: Little is known about the relative effectiveness of calcium supplementation from food or pills with or without vitamin D supplementation for bone mass accrual during the rapid growth period. OBJECTIVE: The purpose was to examine the effects of both food-based and pill supplements of calcium and vitamin D on bone mass and body composition in girls aged 10-12 y. DESIGN: This placebo-cont

Solida tumörer t ex bröst- och prostatacancer är till skillnad från ickesolida tumörer som blodcancer/leukemi ofta dåligt försedda med syre på grund av långa avstånd mellan tumörceller ochNeuroblastoma is a childhood tumour derived from cells of the sympathetic nervous system, which are arrested at low differentiation stages. Low differentiation stage and high tumour stage correlate to poor outcome. In earlier studies we have found that hypoxia induces dedifferentiation of neuroblastoma cells, which implies that hypoxia evokes a more aggressive phenotype. Here we employ microarray
By exploiting the relative motion between the target and the radar, high-resolution images of moving targets can be produced using inverse synthetic aperture radar (ISAR). Recent studies have shown that accurate ISAR images can be obtained using the non-parametric high-resolution Capon and APES spectral estimators. In this paper, we propose a computationally efficient time-updating of the two-dime

High-fat diets are often associated with greater caloric intake and weight gain. Since satiety during fat intake is induced by fat in the intestine we investigated the efficiency of a lipid compound that retards fat digestion to regulate fat intake. We found this compound to reduce high-fat food intake, body weight and blood lipids in Sprague-Dawley rats, without causing steatorrhea. The absence o
To study the impact of canopy exchange on differences observed between atmospheric deposition and throughfall fluxes, several-held experiments were performed at the Speulder forest in The Netherlands. Relevant information was obtained by (i) measuring open-field precipitation and throughfall fluxes with different time resolutions, using two canopy exchange models, (ii) by comparing results from su
