Wall displacements and ground pressure acting on the lining of a tunnel increase with time. These time-dependent deformations are both due to face advance effect and to the time-dependent behavior of the rock mass.  Viscoelastic materials exhibit both viscous and elastic behaviors. Thorough this study, the effect of different linear viscoelastic models including Maxwell, Kelvin and Kelvin-Voigt...

Study Links Use of Face Masks to Improved Cardiovascular Outcomes Air pollution from traffic and industrial sources increases cardiovascular morbidity and mortality, especially in populations with underlying cardiovascular disease. Environmental interventions to reduce pollution would be ideal, but their implementation may be hampered in countries where emissions reductions are trumped by econo...

FACE TO FACE: FRANCO BELTRAMETTI AND JUDITH DANCIGER: A COUPLE OF TRANSLATORS
 In 1973 Franco Beltrametti, a Swiss author strictly connected to both the authors of Beat Generation and those Italian neo-avant-garde (Gruppo 63), published bilingual collection poems in English that he significantly titled Face face (Grosseteste, England). As stated book itself, versions are translations by hi...

The equations for the earthquake forces on a rigid dam with an inclined upstream face of constant slope are solved exactly by two-dimensional potential-flow theory. The distribution of the hydrodynamic pressure along the upstream face and the total horizontal, vertical and normal loads on the dam are computed from the integral solutions. The results obtained from the exact theory are compared w...

We present a surface-mountable miniature Fabry-Perot (FP) pressure sensor that utilizes the total internal reflection at a 45 degrees angled fiber end face to steer the optical axis by 90 degrees . By using the fiber as a waveguide, as well as a natural mask in photolithography, an FP cavity is constructed on the sidewall of the fiber. A polymer-metal composite diaphragm is employed as the pres...

X-ray diffraction data obtained under nonhydrostatic compression of a polycrystalline sample yield an estimate of the single-crystal elasticity tensor of the material when analyzed using appropriate equations. The analysis requires as input the aggregate shear modulus from independent measurements. The high-pressure elastic moduli of face-centered-cubic FeO, body-centered-cubic iron (a-Fe), and...

Introduction: The present study aimed to compare the filtration performance between neat hybrid electrospun nanofibers consisting of polyacrylonitrile (PAN) polymer and magnesium oxide (MgO) nanoparticles and plasma treated ones in removing fine particles from the air stream. Methodology: The upper surface of the nanofibers were processed by cold-plasma with a radio frequency power supply (13....

Concrete faced rockfill dams (CFRDs) are among the structures that due to their advantages such ease of construction and low execution costs,have attracted more attention nowadays.Due to the fact that during large earthquakes,the hydrodynamic pressure will be large and cannot be ignored,the main purpose of this research is to apply reservoir hydrodynamic pressure of dam reservoir caused by the ...
