The direct scattering problem for an inhomogeneous lossy medium is examined for the one-dimensional case in which the phase velocity profile is discontinuous at the boundaries of the medium. Scattering operators (or impulse responses) and propagation operators are defined and equations that govern their behavior are developed. Knowledge of the scattering kernels for one round trip in the medium im

The effect of various antipsychotics during pregnancy has repeatedly been studied, but for most atypical antipsychotics, only little information is available. We identified from the Swedish Medical Birth Register 2908 women who had reported the use of any antipsychotic or lithium in early pregnancy and studied malformation rates with data also from the Register of Congenital Malformations and the

OBJECTIVES: To determine the agreement between transvaginal ultrasound examinations performed before and at saline contrast sonohysterography (SCSH) with regard to number, size and shape of Cesarean section (CS) scar defects. METHODS: In all, 108 women underwent transvaginal ultrasound examination with SCSH at least 6 months after CS: 68 had undergone one CS, 32 two CSs and eight women had undergo

Immunotherapy of malignant primary brain tumors holds the potential to improve the dismal prognosis after current clinical therapy. Although immunotherapy of experimental gliomas has been demonstrated to have the capacity to cure intracerebral tumors no convincing effects of immunotherapy have been shown in clinical trials. One reason for this could be that some of the models used do not display f

The resolution of normative conflicts is a recurring issue for the application of international law, more so now than ever before. To help lawapplying agents to justify decisions resolving a conflict between two norms,international law provides a host of different conflict rules. As several studies reveal, to apply such a conflict rule, law-applying agents often have todraw on political considerat

The proper function of mammalian mitochondria necessitates a coordinated expression of both nuclear and mitochondrial genes, most likely due to the co-evolution of nuclear and mitochondrial genomes. The non-protein coding regions of mitochondrial DNA (mtDNA) including the D-loop, tRNA and rRNA genes form a major component of this regulated expression unit. Here we present comparative analyses of t

Discussion about the film ALI (US, Michael Mann, 2001)

This paper presents an innovative research on urban risk reduction and climate change adaptation that combines case studies, grounded theory and systems analysis, which could be used as a template for similar intersectoral and interdisciplinary investigations. Such a ‘case studies–grounded theory–systems analysis approach’ permits a grounded theory to be built from case study data, which is viewed

En ansökan om betalningsföreläggande avvisas eller avskrivs för att gäldenären inte kan delges. Borgenären ansöker om stämning avseende samma sak. En omtvistad fråga — som rör förenklade tvistemål och tolkningen av 18 kap. 8 a § sjätte stycket rättegångsbalken — är om borgenären i tingsrättsförfarandet kan få ersättning för kostnaden hos Kronofogdemyndigheten. I denna artikel argumenteras för att
