this paper presents a description of the equipment, testing procedure, and methodology to obtain ground mechanical parameters. the p-y curves for laterally loaded piles are developed. methods for the development of p-y curves from pressure meter and dilatometer (dmt) test are described. p-y curves are used in the analysis to represent lateral soil-pile interaction. the pressure meter offers an ...

an interaction potential at different orientation for the ch4 and co2 complex was derived at theb3lyp level of theory and 6-31+g* basis sets. the potential energy surface was computed on somemolecular geometries. the complete basis set limit of the interaction energies were fitted to wellknownanalytical functions. to determine the second virial coefficients b, u(r) is used to obtain themodel’s ...

Current age is the age of globalization. An age in which the conceptual and semantic frameworks has immersed, compacted, and materialized human beings in the same texture. Hypermedia systems has turned knowledge into a wall-to-wall neighbor and cognitive geography has made people closer together. The world has gotten rid of scattering and dispersion, and the global village or meta-geographical ...

the character of the intermolecular interactions in cl2-hx (x =f, cl and br) complexes has been investigated by means of the second-order möller–plesset perturbation theory (mp2) and the density functional theory (dft) calculations. the results show that there are two types of lowest interaction potential equilibrium structures in the interactions between cl2 and hx: x∙∙∙cl type geometry and hy...

the magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. the magnetoresistance is calculated in the ballistic regime, within the landauer-büttiker formalism. it has been demonstrated that the conductance of a magnetic nanowire with double domain walls can ...

in this research, the interactions of hcn gas with pristine, ga-, n- and gan-doped of boron phosphide nanotube (bpnts) were investigated by using density function theory (dft). the structure, electrical and nqr parameters, quantum descriptors involving energy gap, global hardness, global softness, electrophilicity, electronic chemical potential and electronegativity were calculated. the adsorpt...

crystallization of aluminum fluoride at atmospheric pressure has been considered. structure, size and shape of crystals formed during the crystallization process have been investigated. by applying the direct analysis method for the existed aluminum in solution, the aluminum fluoride nucleation process has been detected as a concentration valley at the outset of crystallization process. the lin...

this paper reports on an exploratory study that explores the instructional patterns within english as a foreign language (efl) secondary school classrooms in syria. recently, the syrian ministry of education (moe) has introduced a new national curriculum which recommends a shift in efl teachers’ instructional practices. despite this costly innovation, there has been no attempt to check whether ...
