He reported fever, night sweats, weight loss of 10 kg over 3 months, haemoptysis and skin ulcers (figure 1). Radiography and chest CT scan (figure 2) showe...

not understand how she came to have parents so entirely different from herself. Spurred by various emotional urges she sets out on a crusade to '' live her own life.'' Usually she discovers herself inadequate to meet life as independently as she would like. She finds also that the consequences of independence are somewhat staggering. It is difficult to understand how anyone who has worked with ...

MOTIVATION We present a new probabilistic model of the evolution of RNA-, DNA-, or protein-like sequences and a software tool, Rose, that implements this model. Guided by an evolutionary tree, a family of related sequences is created from a common ancestor sequence by insertion, deletion and substitution of characters. During this artificial evolutionary process, the 'true' history is logged an...

The stopped-flow mixing technique was used to develop a very fast, sensitive and accurate method for determining total proteins. The method is based on the lower fluorescence of Rose Bengal caused by binding of the dye to the proteins. The decrease in the fluorescence intensity, measured at 572 nm with excitation 555 nm, was linearly related to protein concentration from 1.3 to 24.5 micrograms ...

investigation of inter-storm variability of runoff and soil loss characteristics helps experts and decision makes better understanding of hydrological response. however, this important has been less considered in the world, especially developing countries. the present study was therefore planned to evaluate the effect of different rainfall intensities and slopes on inter-storm variability of co...

The weather in Eurasia, Australia, and North and South America is largely controlled by the strength and position of extratropical storm tracks. Future climate change will likely affect these storm tracks and the associated transport of energy, momentum, and water vapour. Many recent studies have analyzed how storm tracks will change under climate change, and how these changes are related to at...

The hippocampal and telencephalon volumes of the nocturnal Leach's storm-petrel (Oceanodroma leucorhoa, n = 15) were compared with published data for food-storing and non-storing Passerines. The hippocampus to telencephalon ratio of Leach's storm-petrels is intermediate between food-storing and non-storing birds. Leach's storm-petrels taken from nesting burrows in wooded habitat had a larger re...
