Maghemite (γ-Fe2O3) nanoparticles have been synthesized using chemical co-precipitation at a different temperature. Characterizations of the sample were performed by X-ray diffraction (XRD), transmission electron microscopy (TEM), alternating gradient magnetometry (AGM) and thermogravimetryanalysis (TGA). The stability of the maghemite nanoparticles suspension was studied at different pH and ti...

The objective of this study was to determine the stability of metronidazole benzoate suspension in SyrSpend SF One-Step Suspension system. The studied samples were packaged in 60-mL amber plastic prescription bottles, which were stored protected from light under controlled environmental conditions for a period of 360 days. Stability of metronidazole benzoate suspension in SyrSpend SF was assess...

Diclofenac is the most widely used non-steroidal anti-inflammatory drug. However, its oral aqueous formulation is not available in market because of its bitter taste and scratching sensation in throat. This study was conducted to develop a stable suspension formulation of diclofenac. Diclofenac acid suspension was prepared by making some modifications in the previously described method. .For st...

We analyse the stability of the spring inverted pendulum with the vertical oscillations of the suspension point. An important factor in the stability analysis is the interaction between radial and oscillating modes. In addition to the small oscillations near the upper position, the nonlinearity of the problem leads to the appearance of limit-cycle oscillations of finite amplitudes.

We study both analytically and numerically the stability of the solutions of the Hébraud-Lequeux equation. This parabolic equation models the evolution for the probability of finding a stress σ in a mesoscopic block of a concentrated suspension, a non-Newtonian fluid. We prove a new result concerning the stability of the fixed points of the equation, and pose some conjectures about stability, b...

An important attribute of cocrystals is that their properties can be tailored to meet required solubility and stability specifications. But before such practical uses can be realized, a better understanding of the factors that dictate co-crystal behavior is needed. This study attempts to explain the phase behavior of anhydrous/hydrated cocrystals when the coformer modulates both water activity ...

A new type of hierarchical fuzzy system (HFS), namely, Hierarchical Classifying-Type Fuzzy System (HCTFS), is developed and proposed in the paper. While the HCTFS enjoys the full benefits of a traditional HFS, one of which is to suppress the effects of the unwanted phenomenon, “the curse of dimensionality,” it also offers one great advantage that all rule strengths are preserved when passing th...

The suspension system is used to observe the vibrations from shock loads due to irregularities of the road surface. It is perform its function without impairing the stability, steering (or) general handling of the vehicle. Generally for light vehicles, coil springs are used as suspension system. A spring is an elastic object used to store mechanical energy and it can be twist, pulled (or) stret...

A polynomial function supervising fuzzy sliding mode control (PSFaSMC), which embedded with skyhook surface method, is proposed for the ride comfort of a vehicle semiactive suspension. The multi-objective microgenetic algorithm (MOlGA) has been utilized to determine the PSFaSMC controller’s parameter alignment in a training process with three ride comfort objectives for the vehicle semi-active ...
