This review encompasses the fundamental aspects of electrophoretic deposition technique, factors influencing the deposition process, kinetic aspects, types of EPD, the driving forces, preparation of electrophoretic suspension, stability and control of suspension, mechanisms involved in EPD, multicomponent/composite deposition, drying of deposits obtained by EPD. Numerous applications including ...
The denaturation behaviour of DNA-protein complexes in metaphase chromosomes in suspension was analysed in situ by Hoechst 33258 fluorescence. The results indicate that due to the stability of the dye molecule and the product of the molecular extinction coefficient and the quantum yield at different temperatures, Hoechst 33258 is a suitable probe for the detection of double-stranded DNA. Thus, ...
The stability mechanism and thermal properties of the system alumina-anionic polyacrylamide (PAM) was studied. The polymer's adsorption properties in dependence on the following parameters solution pH (in the range 3-9), temperature (in the range 15-35 °C), and carboxyl groups' content in the PAM chains (in the range 5-30 %) were examined. The turbidimetry method was applied for determination o...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
In this paper, dynamics, postural stability and control of suspended wheeled mobile manipulators for cooperative heavy object manipulation are elaborated considering the effect of grasping posture. The presented model considers a system equipped with multiple manipulators with flexible suspension, which also contains an accurate nonlinear behavior of the tires. Moreover, it includes the vibrato...
Personalized medicine is a challenging research area in paediatric treatments. Elaborating new paediatric formulations when no commercial forms are available is a common practice in pharmacy laboratories; among these, oral liquid formulations are the most common. But due to the lack of specialized equipment, frequently studies to assure the efficiency and safety of the final medicine cannot be ...
Potential release of soil colloids into groundwater has attracted considerable attention because of their association with heavy metals. Much effort has been focused on using colloid-depositionbased parameters (batch experiment) to predict colloid release in soils (column experiment), though they are two separate processes. In this paper, relative colloid stability ratio was estimated and used ...
Suspensions are one of the most important dosage forms under liquid orals. A large number of drugs are formulated as suspensions considering their therapeutic and commercial benefits. The aim of the present study is to formulate paracetamol suspensions employing Plantago ovata mucilage as a suspending agent and evaluate the sedimentation stability using near infrared transmission measurements. ...
Viruses may remain infectious outside the host cell for considerable time and represent a source of accidental infection if not properly inactivated. In this study, the survival of vesicular stomatitis virus (VSV) in suspension and dried on surfaces was analyzed. In addition, the sensitivity of VSV to disinfectants and physicochemical changes was investigated. VSV showed a notable stability in ...
The purpose of the sliding mode controller for a vehicle suspension system is to reduce the discomfort sensed by passengers which arises from road roughness and to increase the ride handling associated with the pitching and rolling movements. This necessitates a very fast and accurate controller to meet as much control objectives, as possible. This paper deals with introducing a new technique s...
