In this experiment effect of two full and half width sinusoidal inner tubes in triplex-tube heat exchanger with phase change material (PCM) was investigated. Length and diameter of the tubes have been chosen such that the area of each tube to be the same. Charging and discharging processes were carried out by inner tube, outer tube and both. Results indicated, PCM melting and solidification tim...

Five new water-soluble derivatives of Nile Red 1-5 were prepared. These benzophenoxazine dyes fluoresce between 640 and 667 nm with quantum yields of 0.17-0.33 in pH 7.4 phosphate buffer, and at slightly shorter wavelengths and higher quantum yields in EtOH. Two dyes, 3 and 4 permeated into Clone 9 cells and selectively stained mitochondria and golgi, respectively.

The extension of limits of X-ray imaging techniques – in terms of spatial and temporal resolution as well as of material contrast – in the energy range from 5 to 70 keV has long exclusively taken place at third generation synchrotron beamlines. Yet, by using the latest generation of lab-sources together with novel X-ray detectors, results from microas well as sub-micrometer imaging are obtained...

root-knot nematodes are one of the limiting factors in seedling production and new olive gardens establishment in iran. in view of find resistance cultivars to root-knot nematodes, importance of careful identification of species and races are clarified. in order to investigate root-knot nematodes on olive, soil and root samples of gardens and nursery in gorgan area were collected. in this study...

A mechanical spike is a device used to mechanically act on the bow shock ahead of an airplane in supersonic ight. This action results in improved ight conditions. We will investigate here the e ects of the axial generation of a two-hundred-micrometer width cylindrical plasma ahead a quasi-realistic nose pro le of centimeter width. The device is named plasma spike by analogy to the above-cited m...

The diameters of pial arteries and veins were continuously monitored by a multichannel videoangiometer through a closed cranial window in 13 cats. Seventy-two arterial portions (diameter 30-283 micrometer) and 103 venous segments (diameter 32-486 micrometer) were studied under resting conditions and during stimulation of the cervical sympathetic chain. Arteries with a diameter of less than or e...

A new worm eel, Neenchelys andamanensis, is described based on a single specimen collected from a depth of 520-531 m, Andaman Sea, eastern Indian Ocean. The new species is similar to N. daedalus, N. nudiceps, and N. similis in its total vertebral count and slender body, however, it differs from the latter three in having a shorter tail (60% TL vs. 70-76%), more numerous preanal vertebrae (77 vs...
