Mixed convection peristaltic flow of Jeffrey nanofluid in a channel with compliant walls is addressed here. The present investigation includes the viscous dissipation, thermal radiation and Joule heating. Whole analysis is performed for velocity, thermal and concentration slip conditions. Related problems through long wavelength and low Reynolds number are examined for stream function, temperature and concentration. Impacts of thermal radiation, Hartman number, Brownian motion parameter, thermophoresis, Joule heating and slip parameters are explored in detail. Clearly temperature is a decreasing function of Hartman number and radiation parameter. 相似文献
The cellular RNA content of mouse fibroblasts incubated with actinomycin decreases at a rate of about 1 to 1.5 per cent per hour, while DNA and protein content remain unchanged. This degradation affects nuclear and cytoplasmic RNA, ribosomal and soluble RNA. The breakdown products appear quantitatively in the acid-soluble fraction of the cells and the medium. Polynucleotides synthesized a short period (120 minutes) prior to exposure to actinomycin are degraded before those synthesized 8 to 12 hours previously. 相似文献

The differentiation of the indirect flight muscles was studied in the various pupal stages of Drosophila. Fibrillar material originates in the young basophilic myoblasts in the form of short myofilamants distributed irregularly near the cell membranes. The filaments later become grouped into bundles (fibrils). Certain "Z bodies" appear to be important during this process. The "Z bodies" may possibly be centriolar derivatives and are the precursors of the Z bands. The first formed fibrils (having about 30 thick myofilaments) are already divided into sarcomeres by Z bands. These sarcomeres, however, seem to be shorter than those of the adult fibrils.The H band differentiates in fibrils having about 40 thick myofilaments; the fibrils constrict in the middle of each sarcomere during this process. The individual myofibrils increase from about 0.3 µ to 1.5 µ in diameter during development, apparently by addition of new filaments on the periphery of the fibrils. The ribosomes seem to be the only cytoplasmic inclusions which are closely associated with these growing myofibrils. Disintegration of the plasma membranes limiting individual myoblasts was commonly seen during development of flight muscles, supporting the view that the multinuclear condition of the fibers of these muscles is due to fusion of myoblasts. 相似文献
Monoclonal antibodies (McAbs) specific for the C-proteins of chicken pectoralis major and anterior latissimus dorsi (ALD) muscles have been produced and characterized. Antibody specificity was demonstrated by solid phase radioimmunoassay (RIA), immunoblots, and immunofluorescence cytochemistry. Both McAbs MF-1 (or MF-21) and ALD-66 bound to myofibrillar proteins of approximately 150,000 daltons; the former antibody reacted with pectoralis but not ALD myofibrils, whereas the latter recognized ALD but not pectoralis myofibrils. Chromatographic elution of the antigens from DEAE-Sephadex, and their distribution in the A-band, support the conclusion that both of these antibodies recognize variant isoforms of C-protein. Since both McAbs react with a protein of similar molecular weight in the A-band of all myofibrils of the posterior latissimus dorsi (PLD) muscle, we suggest that either another isoform of C-protein exists in the PLD muscle or both pectoralis and ALD-like isoforms coexist in the A-bands of PLD muscle. 相似文献

Plant-derived smoke plays a key role in plant growth. Proteomic technique was used for underlying mechanisms of plant-derived smoke on the growth of soybean (Glycine max L.) under flooding stress. The length and weight of soybean root increased with 2000 parts per million plant-derived smoke under flooding stress within 4 days. Altered proteins by plant-derived smoke treatment under flooding stress were mainly related to protein metabolism, stress, and redox. Furthermore, proteins related to mitochondrial electron transport chain decreased by flooding stress; however, they increased by addition of plant-derived smoke under flooding stress. Based on the results of proteomic analysis, confirmation experiments were performed. ATPase abundance and ATP content increased with the treatment of plant-derived smoke under flooding stress. Furthermore, the ascorbate/glutathione cycle was activated with the treatment of plant-derived smoke under flooding stress. These results suggest that plant-derived smoke improves the root growth of soybean with energy production and reactive oxygen scavenging even if it is under flooding stress, which might positively regulate soybean tolerance towards flooding stress.
Nano materials with high surface area increase the kinetics and extent of the redox reactions, thus resulting in high power and energy densities. In this study high surface area zinc oxide nanorods have been synthesized by surfactant free ethylene glycol assisted solvothermal method. The nanorods thus prepared have diameters in the submicron range (300∼500 nm) with high aspect ratio. They have uniform geometry and well aligned direction. These nanorods are characterized by XRD, SEM, Specific Surface Area Analysis, solubility in alkaline medium, EDX analysis and galvanostatic charge/discharge studies in Zn/AgO batteries. The prepared zinc oxide nanorods have low solubility in alkaline medium with higher structural stability, which imparts the improved cycle life stability to Zn/AgO cells. 相似文献
