The occurrence of transgenic herbicide-resistant oilseed rape (Brassica napus) in ruderal (non-crop disturbed) areas has not been investigated previously in Canada. The primary objective of this study was to document their occurrence in two main ruderal areas (along railways and roads) in the province of Saskatchewan, where half of all oilseed rape is grown, and at the port of Vancouver, Britis...

For the Round Table participants, the idea implicit in the separation between infrastructure manager and providers of transport services in the rail sector is actually to end another form of separation, namely that between the railways and the transport market. Many experts think that a single national railway undertaking is far too rigid to be able to develop a full range of products capable o...

This paper reports some results of a long-term work in application of AI techniques whose ultimate goal is the development of tools for resource scheduling. Most of the efforts so far have been devoted to crew scheduling in railways and the resulting tool is called CREWS. CREWS contains the basic knowledge for crew scheduling, remains constant across companies, and only needs to be extended wit...

There are very similar features between Chinese Railways and European Railways in terms of train operation mode and train control. ETCS (European Train Control System), supported by the European Union and the European Industrials, has been finalized as the technical standard of train control systems in Europe after more than ten years effort. There is more than 71,500 kilometers of railway oper...

Road and railway networks are pervasive elements of all environments, which have expanded intensively over the last century in all European countries. These transportation infrastructures have major impacts on the surrounding landscape, representing a threat to biodiversity. Roadsides and railways may function as corridors for dispersal of alien species in fragmented landscapes. However, only f...

Progress of construction technology Japan has a relatively small proportion of lowland, consisting mainly of alluvial coastal plains. Railway construction started in the early Meiji Era (1868–1912) and since the construction technology was still immature, the first lines were built in level coastal areas. The rails were laid mostly on earth structures such as embankments and cuttings. Many rail...

A second of magnitude 7.5 struck near city Elbistan few hours later. Both these events are associated with system. The sequence caused widespread damage and collapse structures densely populated areas throughout Southern Turkey Nort...
