In the present research, the aqueous suspensions of nano-sized YSZ particles were prepared using a common and available dispersant (Dolapix CE64) at different pH values and their stability were evaluated through the sedimentation height, viscosity measurement, and microstructural observation. Different amounts of dispersant were tested and the optimum percentage was examined by measuring the vi...

the pharmacokinetic properties of amoxicillin and clavulanic acid when used alone or in combination may be different and show interaction between these two agents that might decrease the absolute bioavailability of clavulanic acid. in an open, randomized, replicated latin square under fasting condition, pharmacokinetics of new formulations of amoxicillin/clavulanic acid were compared with a ref...

A bearingless induction machine has combined characteristics of induction motor and magnetic bearings. Therefore, the advantages are small size and low-cost. In the magnetic suspension of the bearingless motors, suspension forces are generated based on the feedback signals of displacement sensors detecting the movement of the rotor shaft. The suspension forces are generated taking an advantage ...

sponge iron (dri) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). in this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. isothermal and non-isothermal re-oxidation experiments were carried out on each type of dri and their autoignition...

the suspension system of a vehicle is one of the most important parts which is involved in the process of vehicle designing. when a vehicle suspension system is designed, the evaluation of its performance against the road disturbances such as shocks and bumps are very important. the most commonly used systems consist of four hydraulic jacks with mobility in vertical line with low speed and low ...

a nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. tire model is based on the elliptic concept and tire calspan data. according to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...

Introduction: The palliative care in patients with bone metastasis includes variety of techniques such as conventional analgesics, surgery, external beam radiotherapy, hormone therapy, chemotherapy and using bone-seeking radiopharmaceuticals. Even some of the recent works used combined methods like chemotherapy and radionuclide therapy or using radionuclide therapy as adjuvant ...

Plant cell cultures could be used as an important tool for biochemical production, ranging from natural pigments to pharmaceutical products. Anthocyanin is affected by a variety of factors. Light, an important plant environmental factor, influences the anthocyanin production in vegetative plant tissues. Here, we have investigated the influence of the blue laser-diode (BLD) and red laser-He Ne (...

In this study, an efficient and facile technique for preparing graphene oxide in suspension and powder forms was presented based on a modification on Hummers' method followed by an additional ultrasonic process. The method involved the provision of graphene oxide from graphite by reaction of potassium permanganate and sulfuric acid with stabilizing the medium complex. Furthermore, this study ev...
