During a 15-y period, 48 children were treated for Wilms' tumour (WT). Seven of them were < 1 y of age at diagnosis. One child presented with non-traumatic haematuria, but in all the other children WT was revealed as a palpable abdominal mass at routine examination or investigation due to another disease. The four children under 6 months of age at diagnosis were primarily operated upon; the others
The drought of 2003 was exceptionally severe in many regions of Europe, both in duration and in intensity. In some areas, especially in Germany and France, it was the strongest drought for the last 50 years, lasting for more than 6 months. We used continuous carbon and water flux measurements at 12 European monitoring sites covering various forest ecosystem types and a large climatic range in ord
The dispersive properties of dielectric materials in both the time and the frequency domains are discussed. Special emphasis is placed on the treatment of heterogeneous materials, particularly two-phase mixtures. A time-domain Maxwell-Garnett rule is derived that differs from the corresponding frequency-domain formula in that it is expressed in terms of convolutions and inverse operators of the su
Mo oxide films were prepared by dual-target reactive DC magnetron sputtering under conditions leading to films that were blue in as-deposited state. The deposition rate for this “blue” Mo oxide was as high as 1.5 nm/s, to be compared to ∼0.85 and ∼0.1 nm/s for highly transparent Mo oxide films made with dual-target and single-target sputtering, respectively. Good electrochromic properties of the “

The paper explores parental perception of social dangers in the urban environment as a constraint for children to walk and cycle. Group discussions with 37 Swedish and 35 English parents of 7 to 12 year old children revealed that social dangers related to strangers, criminality and drugs concerned parents in both countries. These concerns also influenced travel mode choices for their children’s jo
Regulation of violaxanthin de-epoxidase (VDE) involves a conformational change at low lumenal pH, followed by binding of the enzyme to the thylakoid membrane. The role of histidine residues in this process was studied by release of unbound enzyme from thylakoids upon sonication, on a pH scale from 4.7 to 7.1. The co-operativity for binding of spinach VDE (four histidines) to the membrane was found
