Loess-Scape in the Dobrudja Plateau (Romania). Landforms and Updated Typology
Present Environment and Sustainable Development, 2018 The study of loess and loess-like deposits in Romania has developed considerably, over the years. C14 dating determined that the last three glaciations (Mindel, Riss, Würm) and, at least, two interglacial periods were recorded in the Dobrudja Plateau ...

Pure bending of pipe-in-pipe systems [PDF]
Thin-Walled Structures, 2019 Abstract Subsea pipelines and PIP systems experience large bending moments during installation and operation. However, unlike single-walled pipelines, the behaviour of PIPs under bending has been only marginally addressed. In the current study, the bending response of PIP systems with diameter-to-thickness ratio (D/t) of 15–40 is investigated. Linear

Influence of piping processes on the relief evolution. Bardenas Reales (Navarra, Spain)
Cuadernos de Investigación Geográfica, 2013 Piping processes are controlled by many interacting factors, such as dispersion index and sodium content, SAR and ESP, together with other important factors as cracking density, slope degree and climate.

Pipe-to-pipe impact program [PDF]
, 1984 This report documents the tests and analyses performed as part of the Pipe-to-Pipe Impact (PTPI) Program at the Pacific Northwest Laboratory. This work was performed to assist the NRC in making licensing decisions regarding pipe-to-pipe impact events following postulated breaks in high energy fluid system piping.
