Research on the transformer oil-based nanofluids (NFs) has been raised expeditiously over the past decade. Although, there is discrepancy in the stated results and inadequate understanding of the mechanisms of improvement of dielectric nanofluids, these nanofluids have emerged as a potential substitute of mineral oils as insulating and heat removal fluids for high voltage equipment. The transfo...

The effect of geometrical parameters and physical-mechanical properties the internal bearing layer a three-layer spherical structure on its dynamic behavior under impulse loading was investigated. A finite-element model created calculations normal deflections stresses layers were performed using Fimap with NX Nastran software calculation complex. Options for reducing negative impact inefficient...

Specific to blast loading, bond shear tests between carbon fiber reinforced polymer (CFRP) strips and concrete have not yet been reported in literature, the best knowledge of authors. Given high potential strengthening with CFRP increase resistance, it is necessary better understand dynamic interaction under impulse. This article presents a new experimental setup developed order study driven co...

The impact of the elasticity polymer filler a three-layer cylindrical structure normal elliptical cross-section on its stress-strain state under internal impulse loading was studied. Determined values and distribution deflections stresses in sections S1 S2. finite-element method calculating (SSS) such by software-calculation complex Fimap with NX Nastran applied. Conclusions were made regarding...

the impulse oscillation system (ios) measures respiratory impedance (zrs) in terms of resistance (rrs) and reactance (xrs) at multiples of 5 hz. these measurements can be used clinically to help diagnose and monitor respiratory disorders, independent of effort. there is, as yet, no information on reference values for ios in iranian adolescents. the predictive equation for resistance and impedan...

Zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. The efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of Na+ and make depolarization Na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. Also it is an effective blocker of one subtype of tetrodoxine (...

This paper reports results from an experimental and computational study on the influence of bend radius internal angle damage impulse transfer characteristics flexible steel V-structures subjected to localized explosion loading. issue has bearing manufacturing V-hulls used for Mine Resistant Ambush Protected vehicles around world. Global transfer, transient deformation were measured during smal...
