The rheological properties of suspensions of bubbles in yield stress fluids are investigated through experiments on model systems made of monodisperse bubbles dispersed in concentrated emulsions. Thanks to this highly tunable system, the bubble size and the rheological properties of the suspending yield stress fluid are varied over a wide range. We show that the macroscopic response under shear...

the manifest of value of colors in nazik al-malaika s poemsali piranishal *khadije hashemi**from the early times, colors have played an important role in developing poeticimages, and colorful images are the realistic and sensory aspects among poets. poetshave used colorful words to explore and explain the relationship between poeticimages and sometimes they have used colorful words to express t...

Meanings are constructed situationally by the participants in interaction, as they construe intent in each other’s uttered words. A well-known story (said to be a favorite of both Vygotsky and Bakhtin) tells of a group of sailors having a nuanced exchange by repeating the same expletive to each other, but with a different intonation and timing at each turn. This polysemousness of words is equal...

The killing of bacterial cells by chemical agents may be considered as the resultant of a reaction between two systems, the cells and their suspending medium and the germicide and its solvent. The method for testing sanitizing agents proposed by Weber and Black (1948) allows evaluation, on the basis of the two systems, of factors such as ions present in the suspending or diluting medium, organi...

Self-suspension intervals are becoming increasingly common in various systems such as: (i) multi-core processors, where tasks running on one core have to synchronize with tasks running on other cores, (ii) heterogeneous ISA multi-core processors, where certain instructions can only be executed on specific processor cores, and (iii) systems with accelerated co-processors such as Digital Signal P...

BACKGROUND Mucilage compounds are pharmaceutically important polysaccharides that have an extensive range of applications, including binding agents, thickeners, water retention agents, emulsion stabilizers, suspending agents, disintegrates, film formers, and gelling agents. A historical approach to medical science written by Iranian scholars could help in identifying excellent ideas and provide...

this study presents the synthesis of polyvinyl acetate (pvac) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (pva) using alkaline alcoholysis. the influence of the molar ratio of hydrolysis catalyst (naoh) to pvac and the time and temperature of the saponification reaction on the degree of hydrolysis and molecular weight of the pva were investigated using response su...

Although some words may be considered to have similar meanings, they cannot be substituted for one anothel without changing the message. Words with similar meanings have similar denotations . Often, however, words with a similar denotation do not have the same connotations. “Denote implies all that strictly belongs to the definition of the word, connote aU of the ideas that are suggested by the...
