In this work, nanocomposite (NC) hydrogels based on polyacrylamide/chromium triacetate were prepared at different reaction mixture (gelant) volumes and their crosslinking process and viscoelastic behaviors were studied. The X-ray diffraction (XRD) patterns taken from the NC hydrogels containing laponite nanoparticles did not show any distinct characteristic basal reflection for all of the NC hy...

conclusions kannada children with rd were particularly poor on simultaneous and successive processing. our results support the heterogeneity view of rd. results independent-samples t tests (two-tailed) showed significant difference between the groups on all the pass component subtests. the pass scores of children with rd were scattered unevenly around the average to well below the average range...

We investigate pressure driven pipe flow of Laponite suspension, as a model thixotropic fluid. The tendency the suspension to age is controlled by addition sodium chloride salt vary ionic strength. use syringe pump prescribe and observe that steady state obtained. Unusually, drop required maintain constant rate decreases with an increase in rate, qualitative contrast expectation for Poiseuille ...

Background and Aims: World Health Organization Global Polio Laboratory Network (GPLN) plays a critical role in the Global Polio Eradication Initiative. Cell culture methods (mostly RD and L20B cell lines) have been used for Enteroviruses and polioviruses isolation, respectively. Cross-contamination among L20B and RD cell lines causes the problem in accuracy of poliovirus surveillance and decrea...

BACKGROUND AND AIM: Although Rubber dam (RD) usage is one of the ideal and standard methods for isolating the teeth in several operative procedures of dentistry, General Dental Practitioners often neglect it. Many studies within several countries have reported various frequencies for RD application. There is no such study for Iran, so we conducted a study to report the frequency of its applicat...

Colloidal hybrids comprise organic and inorganic components and are attracting considerable attention in the literature. Recently, we reported hybrid anisotropic microsheets that formed thermoresponsive gels in polymer solutions [Liu et al., Langmuir, 25, 490, 2009]. Here, we investigate the composition and properties of these hybrid colloids themselves in detail for the first time. Three diffe...
