The paper presents research on expedient repairs, including battle damage repair methods of hydro-pneumatic pipes with adhesives. According to analyzed publications concerning battle damage of military equipment, various pipes and lines, which are used in military vehicles and aircrafts, are one of the most often damaged parts during combat operations. During experimental tests, the efficiency ...

Field and Scott Smith [Field, M., Scott Smith, B.H., 1999. Contrasting geology and near-surface emplacement of kimberlite pipes in southern Africa and Canada. Proc. 7th Int. Kimb. Conf. (Eds. Gurney et al.) 1, 214–237.] propose that kimberlite pipes can be grouped into three types or classes. Classical or Class 1 pipes are the only class with characteristic low temperature, diatreme-facies kimb...

The purpose of the air distribution system in a fluidised bed combustor is to provide a reasonably uniform spread of combustion air over the entire horizontal cross-sectional area of the bed. One of the simplest, and hence cheapest, forms of air distributor is the sparge pipe design, in which an array of horizontal pipes is fitted at the base of the bed. Combustion air is then supplied to one e...

The paper sketches KURT, an autonomous robot platform prototype that is able to navigate inside a network of sewage pipes. KURT is a six-wheeled device; it has modular, layered hardware and control architectures. Its sensor connguration consists mostly of stationary and one exible ultrasound sensors and of two inclinometers. In experiments run in a test sewerage system consisting of concrete pi...

1. ABSTRACT It has been about fifty years ago since the first unplasticized poly(vinyl chloride) (uPVC) pipes were installed for use in gas distribution purposes. Currently, about 22,500 km of uPVC is still in use in the Dutch gas distribution network. The pipes were originally designed for a lifetime of 50 years, but due to positive experiences the question arises if (and how long) the lifetim...

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...

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...
