Great efforts have been recently made in the world of metallurgy in order to reduce raw material consumption and particularly energy consumption. Although most metallurgical products are produced by the proved procedures of plastic forming, some changes appear owing to the following requirements: – improvement of product quality, – reduction of production costs, – increase of productivity as we...

This report presents Semantic Web pipes, a powerful paradigm to build RDF-based mashups. Semantic Web pipes work by fetching RDF models on the Web, operating on them, and producing an output which is itself accessible via a stable URL. We illustrate how Semantic Web pipes can solve use cases ranging from simple aggregation to complex collaborative editing and filtering of distributed RDF graphs...

The roll forming industry has many difficulties in product development and process set-up. The design and development of rolls and processes re mainly based on trial-and-error and past experiences. Recent industrial trends demand products having high quality and tight tolerances. This equires more precise and cost-effective roll-forming processes than the ones employed in the traditional produc...

corrosion makes huge economic and ecologic damage all over the world. biologic corrosion of sewer pipes is considered as a serious limitation in economic perspectives. to prevent biologic corrosive damage, lining techniques can be applied by materials and aggregate resistant to attack bacterially in sewer pipes. the role of bacteria is that they convert sulfur compounds into sulfuric acid which...

Soil pipes are common and important features of many catchments, particularly in semi-arid and humid areas, and can contribute a large proportion of runoff to river systems. They may also significantly influence catchment sediment and solute yield. However, there are often problems in finding and defining soil pipe networks which are located deep below the surface. Ground-penetrating radar (GPR...

Using single-electrode current-clamp and two-electrode voltage-clamp, different identified neurones of the leech (Hirudo medicinalis L.) were shown to hyperpolarize, or to exhibit outward currents (usually >2 nA), during bath application of the organic buffers Mops, Pipes and Mes (10 mmol l-1). Tris and Hepes had little or no effect on the membrane properties of neurones when they were added to...
