Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...

The rheological properties of soft rocks should be considered in the long-term design and maintenance deep-buried tunnels using uniaxial single-stage loading graded incremental cyclic-loading methods. In this article, creep tests were performed on silty mudstone from a specific water conveyance tunnel China, with buried depth range 1650–2320 m subjected to high situ stress. curves under differe...

Recent advancements in the inhalable, injectables, transdermal, nasal and other routes of administration, the unavoidable truth is that oral drug administration has been the preferred route for the drug delivery. There are sure components like poor medication solvency or retention, quick digestion system, high change in the medication plasma level and variability in quick and encouraged impact,...

To restore declining species, including Populus euphratica and other riparian communities, in the river ecosystem of the lower Tarim River, the ecological water conveyance project (EWCP), as a part of an integrated water resource management plan, was implemented in 2000. The EWCP aims to schedule and manage the water resources in the upper reaches and transfer water to the lower reaches by a se...

E. Azadegan , R. Ezzati Department of Mathematics, Islamic Azad University-Karaj Branch, Karaj, Iran |||||||||||||||||||||||||||||||Abstract In this paper, we present a new two-parameters family of iterative methods for solving non-linear equations and prove that the order of convergence of these methods is at least four. Per iteration of these new methods require two evaluations of the functio...

A system dynamics model was developed to estimate the carbon dioxide (CO2) emissions associated with conveyance of water from the water source to the distribution laterals of the Las Vegas Valley. In addition, the impact of several water management policies, including water conservation, reuse, and population growth rate change was evaluated. The results show that, at present, nearly 0.53 milli...

We assessed the water requirements of ethanol from corn grain and crop residue. Estimates are explicit in terms of sources-green (GW) and blue (BW) water, consumptive and nonconsumptive requirements across the lifecycle, including evapotranspiration, application and conveyance losses, biorefinery uses, and water use of energy inputs, and displaced requirements or credits due to coproducts. Etha...
