Semi-buried structures are most commonly used at first line of defense along the border between two countries. This demands investigation of their dynamic behaviour under blast loading. Herein, a semi-buried structure with foam sandwiched walls and buttresses to reduce the effect of blast is analysed. The effect of provision of different configurations of buttresses and foam core between two la...
The soil stabilisation is employed to construct geostructures as embankments, river levees, road subbases or backfill excavations, improving the mechanical behaviour and reducing consumption of extracted primary aggregates. This study focused on use lime/cement treated soils trenches where high power line cables are buried. Indeed, under these circumstances not only properties but also thermal ...
residues (Franzluebbers et al., 1994; Rovira and Vallejo, 2002). Maintaining soil C is especially difficult in hot climates. Information Soil C decomposition and retention also depend on is needed regarding the influence of residue biochemical properties residue biochemical quality (Melillo et al., 1982; Heal on decomposition in hot, semiarid climates so that management pracet al., 1997; Senevi...
Understanding soil-pipe interaction during cyclic axial displacement is essential for the design and evaluation of buried pipeline systems. This study introduces an efficient practical numerical approach using beam-spring-interface elements to simulate behaviour. Numerical predictions evolution shear normal stress distributions around pipe are validated against full-scale experimental results s...
of the many diverse arts that flourished during the third millennium bc, textiles played an especiallysignificant role in society. archaeological textiles offer an important source of material cultural testimony fordaily life in ancient times- relating simultaneously to agriculture, pastoralism, trade, migration, ritual, and soforth as well as to craft technologies. the study of the techniques ...
Combined ground penetrating radar and metal detector equipment are now available (e.g., MINEHOUND, ERA TechnologyVallon GmbH) for landmine detection. The performance of the radar detector is influenced by the electromagnetic characteristics of the soil. In this paper we present an experimental procedure that uses the same equipment for the detection and calibration by means of signal processing...
There are 2 types of distraction devices for mandibular distraction: buried and external. The advantage of buried devices is the stability, but the difficulty in removing the screws is the greatest disadvantage. To resolve this problem, an osteosynthesis screw (Fariña Screw) has been designed, which greatly facilitates its removal when buried distractors are used.
Loess/soil sequences have been proven to be excellent paleoclimate indicators. Large areas of northern Iran are covered by loess deposits which provide a good condition to carry out research on paleoclimate, paleosols and discontinuities. The objectives of this research were to identify clay minerals of soil-loess sequences, to determine the role of climate change in clay mineral transform...
