medicinal plant species constitute a considerable part of the flora in iran and play a major role in the composition of plant communities. therefore, it is necessary to recognize the factors leading to the establishment and distribution of vegetation. for data sampling (2012), land units were specified. the plot size was determined using minimal area method and number of plots was determined by...

GLORIA sidescan imagery, multibeam bathymetry, seismic profiles, and piston cores (3-5 m penetration) reveal the near-surface geology of the Bryant Canyon turbidite pathway on the continental margin of Louisiana. This pathway extends from the continental shelf edge, across the continental slope, to a deep-sea fan on the continental rise. The pathway is narrow (<2 km) where it crosses shallow sa...

The belled anchor pile has proficient application in the field of geotechnical engineering as because its enlarged base can bear more compressive loads and large volume of breakout soil within slip surface move upward under tension. The bell anchor pile can be used in case of on-land and off-shore structures where there is a threat to overturning of structures due to external tension loads. The...

Each year, the number of scrap tires disposed in huge piles across world continuously increases. Consequently, new recycling solutions for these materials have to be proposed. Among them, one possibility consists shredding and mixing obtained tire chips with sand, which can used as alternative soils various geotechnical applications, such backfilling retaining structures, slope highway embankme...

Free gas in sandy marine sediments is a common occurrence worldwide. A distinct feature of gassy sand that, under undrained shearing, presence occluded bubbles the pore fluid can increase strength at relatively loose state, while reduce dense sand. Previous theoretical analyses have primarily focused on modelling ‘beneficial’ effect free migrating static liquefaction, with few attempts to descr...
