This paper provides an overview of the DITTO (Developing Integrated Tools to Optimise) project and presents some of its initial findings. The aim of DITTO is to increase the practical capacity of railway systems by developing computerised tools that can determine the theoretical capacity of a given infrastructure, optimise timetables in the face of delays and optimise real-time traffic manageme...

Summary Specimens of a thin longidorid species collected in Peñalba (Huesca), north-west Spain, were previously described as Paralongidorus iberis . However, we conclude, through scanning electron microscopy and molecular studies on population from about 15 km the type locality paratype specimens, that this was originally placed wrong genus. Both populations have pore-like amphidial apertures, ...

results of the 100 klebsiella isolates, 41 (41%) demonstrated resistance or reduced susceptibility to ceftazidime and/or aztreonam and 35% (n = 35) were esbl-producers. twenty-eight (8o%) of the esbl-producing isolates carried the blactx-m type genes. based on pcr assays and sequencing of blactx-m genes, ctx-m-1, ctx-m-2 and ctx-m-9 were identified in 21 (60%), 15 (42%) and nine (34%) of these ...

Joints and fissures in natural rocks have a significant influence on the stability of the rock mass, and it is often necessary to evaluate strength failure and crack evolution behavior. In this paper, based on experimental tests and numerical simulation (PFC2D), the macro-mechanical behavior and energy mechanism of jointed rock-like specimens with cross non-persistent joints under uniaxial load...
