Purpose With respect to two new subjects, i.e. nanofluids and microchannels, in heat transfer systems and modern techniques used for building them, this paper aims to study on effect of using aluminum oxide nanoparticles in non-Newtonian fluid of aqueous solution of carboxy-methyl cellulose in microtube and through application of different slip coefficients to achieve various qualities on surface of microtube. Design/methodology/approach Simultaneously, the effect of presence of nanoparticles and phenomenon of slip and temperature jump has been explored in non-Newtonian nanofluid in this essay. The assumption of homogeneity of nanofluid and fixed temperature of wall in microtube has been used in modeling processes. Findings The results have been presented as diagrams of velocity, temperature and Nusselt Number and the investigations have indicated that addition of nanoparticles to the base fluid and increase in microtube slip coefficient might improve rate of heat transfer in microtube. Originality/value The flow of non-Newtonian nanofluid of aqueous solution of carboxy methyl cellulose-aluminum oxide has been determined in a microtube for the first time.

The distribution of cellulase in the class Bivalvia is studied with respect to phylogenetic position, feeding category, and food. Cellulase activity in nine species is measured turbidimetrically using reprecipitated cellulase substrate, colorimetrically using methyl cellulose substrate, and histochemically with methyl cellulose film. Cellulolytic activity in these animals generally corresponds to the level of cellulose in the food. Those animals feeding on particles with a high cellulose content have high cellulase levels, while those organisms feeding on epiorganisms, diatoms, or phytoplankton with low cellulose content have low cellulase levels. The Gastrotriteia may have characteristically higher endogenous cellulase levels than the other major groups and certain genera may have characteristically low cellulase activity.
