Pipe dreams represent permutations pictorially as a series of crossing pipes. Recent applications of pipe dreams include the calculation of Schubert polynomials, fillings of moon polyominoes, and in the combinatorics of antidiagonal simplicial complexes. These applications associate pipe dreams to words of elementary symmetric transpositions via a canonical mapping. However, this canonical mapp...

An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing perfor...

Soil piping is a complex mechanism of subsurface soil erosion, which results underground conduits (cave/tunnel) varying dimensions. associates with severe consequences, such as land subsidence and slide. Therefore, the investigation pipe crucial. However, study challenging unless characteristic surficial evidences are available. Based on evidences, can be configured geophysical techniques in-tu...

This paper presents, a set of experiments was conducted in a Plexiglas flume setup to investigate the simultaneous use of pipe and blade in the scour control around a submerged pipe. A vertical cylindrical pipe with and without a blade placed below it was selected for the experiments. The experiments were carried out in two different sates: with blade and without blade the pipe. Moreover, they ...

The adoption of Health IT has been argued to bring about improvements in adopting hospitals. However, examining a panel of hospitals for the adoption of IT, we find that close to 50% of hospitals that adopt a health IT system go on to stop using it during the duration of our panel.1 We find that smaller hospitals and hospitals that are located in areas that have low IT-Intensity are more likely...
