In the present work, the sensitivity to the moisture (hygroscopisity) is studied for 3,4-dinitropyrazole (DNP) as a famous energetic molecule. All of the DNP-H2O complex systems (1-3) as well as individual molecules were optimized and bond lengths, bond angles, dihedral angles, charge transfer and stability via NBO analysis, corrected interaction energies with ZPE + BSSE and hydrogen bonds anal...

Background: Colorectal cancer (CRC) is the third most common cancer worldwide. microsatellite instability (MSI) is a molecular marker of a deficient mismatch repair system and happens in almost 15% of CRCs. Because of a wide frequency of MSI+ CRC in Iran compared to other parts of the world, the importance of screening for this type of cancer is highlighted. Methods: The most common MSI detecti...

Ocean platforms that are under complex sea conditions and loads for long periods prone to fatigue cracks. These cracks may lead large deformations, even displacement, of the platform, should be monitored ensure engineering safety. Cracks not easily detected in micro stage small levels strain measurement required high accuracy. Furthermore, suddenly developing into especially structural connecti...

In this paper the effect of corrugated diaphragm on performance of MEMS microphone is described. The corrugated diaphragm is modeled in order to improve the sensitivity of micromachined silicon acoustic sensor. Analytical analyzes have been carried out to derive mathematic expressions for the mechanical sensitivity and displacement of corrugated diaphragm with residual stress. It is shown that ...

In the present study, mechanical behavior of tricuspid valve (TV) chordae tendineae tissue is investigated experimentally and theoretically. A series uniaxial testing experiments TV conducted its viscoelastic model developed by taking into account initial condition displacement tissue. Our experimental result shows typical J-shaped force-displacement curve corresponding established via a nonlin...

Grey correlation theory is an uncertainty analysis method, which can find the relevance of various factors studied through certain data processing in incomplete information and main influencing factors. In order to study influence vehicle load on vibration underground civil air defense construction, taking construction at intersection Zhongzhou Middle Road Shachang South Luoyang as subject, bas...

the issue of successful project management and control is of vital importance in today’s world. although the time and cost of any project is determined in advance, paying less attention to an appropriate control and revision will result in a small chance of reaching those goals. the earned value management method that shows deviation of projects schedules and costs is of the good method for thi...
