We present a novel active mixing method in a microfluidic chip, where the controlled stirring of magnetic particles is used to achieve an effective mixing of fluids. To perform mixing, the ferromagnetic particles were embedded and manipulated under the influence of a rotating magnetic field. By aligning the magnetic beads along the magnetic field lines, rod-like structures are formed, functioni...

A cytogenetical study on 13 alfalfa (Medicago sativa) cultivars available in Iranian Forest and Rangelands Genebank was performed in order to obtain basic information on the variability in chiasma frequency/distribution, chromosome association and segregation. Such cytogenetic information is useful for planning hybridization programs. Cluster analysis of meiotic data and ordination of cultivars...

The current research focuses on understanding the transition of pipe flow by using a triggering device. In particular, rod was installed within CoSma-Pipe at Brandenburg University Technology Cottbus-Senftenberg. effect rod, which has variable height perpendicular to axis inlet, examined in range 2,500 ≤ Re 31,000 where is Reynolds number based mean velocity, diameter, and air's viscosity. This...

Fano resonances in plasmonic nanostructures, generated by the spectral interference between a broad resonance or continuum and narrow resonance, have attracted significant interest recent literature. Herein, introducing nanodisc next to nanoring via electron beam lithography, set of for such ring-disc-pair (RDP) hybrid is confirmed through coupling dipolar disc mode different multipolar bonding...

We have measured the spatial density of cones and rods in eight wholemounted human retinas, obtained from seven individuals between 27 and 44 years of age, and constructed maps of photoreceptor density and betweenindividual variability. The average human retina contains 4.6 million cones (4.08-5.29 million). Peak foveal cone density averages 199,000 cones/mni2 and is highly variable between ind...

A rectangular rod is placed in a flow field flowing parallel to a flat plate. Effect of chord-thickness ratio of rectangular rod on developing vortex shedding downstream to the rod is studied. Then, for each one of the aspect ratios, the distance of the rod from the neighboring flat plate is reduced until the rod sticks to the flat plate. In each case, the effect of the flat plate boundary laye...
