High doses of intrathecally applied morphine or morphine-3 D-glucuronide (M3G) produce allodynia and hyperalgesia. Whole-cell patch-clamp recordings were made from substantia gelatinosa neurons in transverse slices of adult rat lumbar spinal cord to compare the actions of M3G with those of the -opioid agonist, DAMGO ([D-Ala,N-Met-Phe,Gly-ol]-enkephalin), and the ORL1 agonist, nociceptin/orphani...

El crecimiento urbano, ha hecho que las edificaciones se sitúen sobre suelos flexibles, la cual su resistencia es pequeña, para desea proyectar, generando problemas de asentamiento estructuras y esfuerzos diseño en losas cimentación. Como alternativa solución, los ingenieros civiles, colocan capas material préstamo (afirmado) el suelo natural, luego ser compactado. Esta técnica logra incrementa...

Abstract A mathematical model for nonlocal vibration and buckling of embedded two-dimensional (2D) decagonal quasicrystal (QC) layered nanoplates is proposed. The Pasternak-type foundation used to simulate the interaction between elastic medium. exact solutions frequency critical load 2D QC are obtained by solving eigensystem using propagator matrix method. present three-dimensional (3D) soluti...

numerous studies have been conducted about the role of media during a crisis. accordingly diverse functions have been defined for media while in crisis. by applying a prescriptive viewpoint to derive mass media functions, most of the studies have been the based on the opinions of experts and the opinions of the victims have rarely been taken into consideration. for the first time, we have direc...

in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...

In this study, a semi analytical method for transverse and axial vibration of single-walled boron nitride nanotube (SWBNNT) under moving a nanoparticle is presented. The surrounding elastic medium as Pasternak foundation and surface stress effect are included in the formulations of the proposed model. Using Timoshenko beam theory (TBT), Hamilton’s principle and nonlocal piezoelasticity theory, ...
