A number of chemicals, mostly adenosine analogues, cause the nucleolus of the chick embryo fibroblast to lose material and unravel over a period of several hours into beaded strands termed nucleolar necklaces (NN). The results of analyses of the fibroblasts, treated with the NN-forming chemical dichlororibobenzimidazole (DRB), suggests that the following biochemical alterations occur: DRB almos...

This article reviews previous studies on micellar structures formed by hydrophobically modified polysaccharides in aqueous solutions static and dynamic light scattering, small angle X-ray neutron fluorescence from pyrene solubilized polymer solution. The experimental results are consistently explained the full or loose flower necklace model for pullulan bearing octenyl groups amylose dodecyl ra...

The Apinayé are a Brazilian indigenous ethnic group that live in transition zone between the Cerrado and Amazon. This study primarily aims to understand meaning art holds for students at Indigenous School. We used an ethnographic research methodology, while also observing classes distributing open questionnaires these students. results showed arts produced by people mostly refer body paintings ...

HBI is an accessories store that sells women's jewelry accessories. Shop various products such as bracelets, rings, necklaces, earrings and other custom Each sales activity must have a document contains information about reports. reports at Stores still use Microsoft Excel, so it takes long time to get report developments. Increasing product requires implementing business strategy improve the q...

The current status of Ultra High Energy Cosmic Rays (UHECR) is reviewed, with emphasis given to theoretical interpretation of the observed events. The galactic and extragalactic origin, in case of astrophysical sources of UHE particles, have the problems either with acceleration to the observed energies or with the fluxes and spectra. Topological defects can naturally produce particles with ene...

We study driven flow with exclusion in graphenelike structures. The totally asymmetric simple exclusion process (TASEP), a well-known model in its strictly one-dimensional (chain) version, is generalized to cylinder (nanotube) and ribbon (nanoribbon) geometries. A mean-field theoretical description is given for very narrow ribbons ("necklaces") and nanotubes. For specific configurations of bond...

We present anO(n) time algorithm for finding the lexicographically largest fixed-density necklace of length n. Then we determine whether or not a given string can be extended to a fixed-density necklace of length n in O(n) time. Finally, we give an O(n) algorithm that finds the largest fixed-density necklace of length n that is less than or equal to a given string. The efficiency of the latter ...

Nanostructured terahertz detectors employing a single semiconducting nanowire or graphene sheet have recently generated considerable interest as an alternative to existing THz technologies, for their merit on the ease of fabrication and above-room-temperature operation. However, the lack of alignment in nanostructure device hindered their potential toward practical applications. The present wor...

Ultra High Energy Cosmic Rays (UHECR) can be a signal from very early (post-infationary) Universe. At this cosmological epoch Topological Defects (TD) and long lived superheavy (SH) particles are expected to be naturally and effectively produced. Both of these relics can produce now the particles, such as protons and photons, with energies in a great excess of what is observed in UHECR, E ∼ 10 ...
