nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
Stepped block protection has considerable potential as a low-cost method for the construction of chute spillways and the protection of embankments from erosion by overtopping flow. Stepped spillways are structurally stable, resistant to water loads and significantly increase the rate of energy dissipation on the spillway face thus eliminating or greatly reducing the need for a large energy diss...
Application of micro-piles to stabilize unstable slopes has been widely considered in recent years. A micro-pile is a small-diameter (typically less than 300 mm), drilled, and grouted as non-displacement pile that is typically reinforced. The main objective of this study is to evaluate the influence of the micro-pile group on increasing safety factor as well as finding the optimum position of m...
a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
City of Vantaa considers constructing a truck parking area and a filling station on a soft clay deposit in Luhtaanmäki, Vantaa (in Finland). The aim of this study was to evaluate whether vacuum preloading with vertical drains is a feasible ground improvement method for the site. Besides in situ –tests and classification tests, overall 18 oedometer tests were carried out. Preliminary design of v...
This paper presents the results of nonlinear numerical simulations carried out to analyze rainwater infiltration through a road embankment structure using the finite element method (FEM) technique. The analysis of this paper includes a simplification of a crosssectional road embankment located in Santander (Northern Spain) and considers different realistic hydraulic material parameters, accordi...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
To study the deformation behavior of high rockfill (HRF) embankment during construction and operation, based on more than a 50-m second-class road reconstruction project from Xunyang to Ankang national 316 in Shaanxi, China, centrifuge model test was performed laws HRF embankment. The results showed following: (i) stable operation; (ii) construction, settlement occurred at top, uplift slope foo...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
the construction of underground tunnel plays a more and more important role in the development of big cities. one of the most important problems caused by the construction of the tunnel is that underground excavation will cause large settlement of the ground and buildings. previous studied showed the difference between numerical and experimental results. in this study the case study of niyayesh...
