We introduce a novel approach to reveal ordering fluctuations in sheared dense suspensions, using line scanning combined rheometer and laser confocal microscope. validate the technique with moderately suspension, observing modest shear-induced nearly linear flow profile. At high concentration ( ϕ = 0.55) applied stress just below shear thickening, we report temporal resolution, directly measure...

Aims: Qualitative analysis of a mucoadhesive polymeric (Carbopol940) suspension of Norfloxacin was carried out with the aim of developing an oral controlled release gastro-retentive dosage form. Methods: The characterization of ultrasonicated formulation was performed by Fourier Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy, Xray powder diffraction (XRD) and Scanning electron micro...

In shallow coastal ecosystems where most of the seafloor typically lies within the photic zone, benthic autotrophs dominate primary production and mediate nutrient cycling and sediment stability. Because of their different structure and metabolic rates, the 2 functional groups of benthic macrophytes (seagrasses, macroalgae) have distinct influences on benthic−pelagic coupling. Most research to ...

in this study the effect of different concentrations of some abiotic elicitors (salicylic acid, jasmonic acid, cadmium chloride and sodium chloride) with different incubation times (3, 6, 9 and 12) on azadiractin production and cell growth in the cell culture of the iranian native neem were investigated. cell growth rate was measured by changes in dry cell weight and it was used as a basis for ...

purpose: to compare the results of two different methods of frontalis suspension using fascia lata in congenital ptosis. methods: in a randomized clinical trial, double triangle sling was compared with single triangle sling using fascia lata. eight patients with unilateral and 11 patients with bilateral congenital ptosis were randomly assigned for each procedure. results: there was no statistic...

in recent years, great efforts have been devoted to the design of drug delivery systems. many polymeric excipients have been studied in order to make drug release fit the desired profiles. the aim of this work was to design a theophylline oral suspension, as sustained release pharmaceutical preparation in order to decrease the plasma level fluctuations and adverse effects of theophylline. micro...

In this paper the importance of self tuning adaptive PID control scheme for automotive suspension system is explained. The objective of this study is to obtain a mathematical model for the passive and semi-active suspension system for quarter car model. Current automobile suspension system employs springs and damper with fixed coefficient. Vehicle suspension systems are typically rated by their...

Cpe mice have a point mutation in carboxypeptidase E (Cpe), an exopeptidase that removes C-terminal basic amino acids from intermediates to produce bioactive peptides. The mutation renders the enzyme inactive and unstable. The absence of Cpe activity in these mutants leads to abnormal processing of many peptides, with elevated levels of intermediates and greatly reduced levels of the mature pep...

Tyrosyl kinase activity in vesicular stomatitis virus (VSV) acquired from host cells that differ in morphology was investigated. VSV grown in baby hamster kidney (BHK) cells with rounded morphology and a high efficiency of colony formation in soft agar (Rous sarcoma virus [RSV]-transformed and suspension BHK cells) was compared with VSV grown in BHK cells with a flattened morphology and lower e...
