Energy sustainability and the establishment of ‘national water network’ are all inseparable from construction underground engineering. Monitoring indices for surrounding rock vital safety management engineering construction, which determines actual state rock. The complexity deep leads to many situations that cannot be predicted explained by existing experience. Therefore, it is necessary ident...

  Abstract   Background: The polymorphic variants at codon 72 of the p53 gene, encoding either   proline or arginine at residue 72, produce marked change in the structure of p53.   From the evidence that the DNAmismatch repair system and p53 interact to maintain   genomic integrity, we hypothesized that the codon 72 variation may influence the   prevalence of microsatellite instability a featur...

Unusual electronic phase transitions in the A-site ordered perovskites LnCu3Fe4O12 (Ln: trivalent lanthanide ion) are investigated. All LnCu3Fe4O12 compounds are in identical valence states of Ln(3+)Cu(2+)3Fe(3.75+)4O12 at high temperature. LnCu3Fe4O12 with larger Ln ions (Ln = La, Pr, Nd, Sm, Eu, Gd, Tb) show an intersite charge transfer transition (3Cu(2+) + 4Fe(3.75+) → 3Cu(3+) + 4Fe(3+)) in...

OBJECTIVE The purpose of this study was to evaluate Doppler flow velocity changes in cerebral vessels of monochorionic twins with twin-twin transfusion syndrome (TTTS). METHODS Repeated Doppler umbilical and cerebral blood flow studies were performed in 7 twin pairs with TTTS. Eight monochorionic twin pairs and 11 dichorionic twin pairs served as control groups. The following Doppler paramete...

the presence of van der waals (vdw) force can lead to mechanical instability in freestanding nano-scale actuators. most of the previous researches in this area have exclusively focused on modeling the instability in actuators with one actuating components. while, less attention has been paid to actuators consist of two actuating components. herein, the effect of the vdw force on the instability...

this paper investigates the relationship between macroeconomic instability and private investment of the iranian economy. the study uses a trivariate var(2)-garch(1,1)-in-mean with diagonal bekk approach to proxied inflation and exchange rate uncertainties as the main indicators of macroeconomic instability. moreover, bounds testing approach to level relationship applied to investigate the long...

in this study a nonlinear asymmetric instability analysis carried out to study primary atomization of annular liquid sheets emanating from the prefilming airblast atomizer using a perturbation method and potential flow assumption. in this direction, firstly governing equations derived according to potential flow assumption and conservation equations while dynamic and static boundary condition a...

We analyze the effect of a highly dispersive element placed inside a modulated optical cavity on the frequency and amplitude of the modulation to determine the conditions for cavity self-stabilization and enhanced gyroscopic sensitivity. Hence, YZ model cavity rotation or instability by an arbitrary AM/FM modulation, and the dispersive element as a phase and amplitude filter. We find that anoma...

BACKGROUND Patellar stabilizing braces are used to alleviate pain and prevent subluxation/dislocation by having biomechanical effects in terms of improved patellar tracking. The purpose of this study is to analyze the effects of the dynamic patellar realignment brace, Patella Pro (Otto Bock GmbH, Duderstadt, Germany), on disease determinants in subjects with patellofemoral instability using upr...
