The attractive force between the nanoparticles can cause them to aggregate. Therefore, nanoparticles have to be dispersed by different methods, in order to utilize their unique material characteristics completely. This study aims to use the self-developed nanofluids synthesis system to produce a Cu-based nanofluid with good suspension stability and particle dispersion. Parameters such as peak c...

Omeprazole is used in the treatment of dyspepsia, peptic ulcer disease, gastroesophageal reflux disease, laryngopharyngeal reflux, and Zollinger-Ellison syndrome. Omeprazole is marketed by AstraZeneca under a number of names, most notably Prilosec and Losec, as well as being available from a number of generic manufacturers. Omeprazole is available in both tablet and capsule form, with varying s...

This paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. Since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

Abstract A method of determining the parameters car suspension has been developed, which allows taking into account influence main characteristics suspension. In particular, static deformation, nonlinearity parameter, and such external factors as movement a over rough terrain, stability are taken account. Mathematical models vertical oscillations - dynamics sprung part vehicle with non-linear f...

The suspension parameters are vital in the suspension-type abrasive water jet (AWJ) machining of several engineering materials, more so difficult-to-cut because it significantly influences stability and sedimentation behaviour mixture particle acceleration into AWJs. AWJs improved by using polymer additives. Hence, is necessary to study effect (abrasive concentrations) on stability. In this dir...

n-sodium acrylate-o-carboxymethyl chitosan [cmch-g-paa(na)] bound fe3o4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. cmch-g-paa (na) was obtained by grafting of sodium polyacrylate on o-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegradability properties. a...

Compared with the traditional automotive suspension, hydro-pneumatic suspension has characteristics of large energy storage ratio, nonlinear stiffness and can change ground clearance vehicle body, which makes have good ride comfort handling stability during driving. In order to improve performance it is necessary design test bench for test. Aiming at problem that output signal mechanical used i...

Compared to mechanical bearings, active magnetic bearings eliminate friction, resulting in lower energy losses. However, due the magnetization characteristics and high-frequency working of core material bearing, there will be high wind friction loss, eddy current hysteresis loss copper bearing. These losses generate heat increase internal temperature which not only affect control accuracy beari...
