In this article, stream flow effectivness is based on hydraulic network studied in the shell-side of a shell and tube heat exchange as a case study. For an appropriate heat exchangers rating design to meet a specified duty, it's better to consider each stream flow separately. Using the hydraulic network principals, a set of the correlations for calculating different stream flow rates in the cro...

Uniaxial compression studies are performed on 50-mm-diameter bundles of nominally vertical, intertwined carbon nanotubes grown via chemical vapor deposition from a photolithographically defined catalyst. The inhomogeneous microstructure is examined, demonstrating density and tube orientation gradients, believed to play a role in the unique periodic buckling deformation mechanism. Through in sit...

We study the tube size and bundling effects on Raman active breathing-like phonon modes (BLM) and tangential-like phonon mode (TLM) of double-walled carbon nanotubes (DWCNT) in the framework of the bond polarization theory, and use the spectral moment’s method. The Raman active modes are calculated for different diameter and chirality of the inner and outer DWCNT tubes. The dependence of the Ra...

We prove that the invariant part, with respect to a compact group action satisfying certain condition, of direct image Nakano positive Hermitian holomorphic vector bundle over bounded pseudoconvex domain is positive. also consider noncompact $${\mathbb {R}}^m$$ and get same result for family tube domains, which leads new method matrix-valued Prekopa’s theorem originally proved by Raufi.

The interaction of the serine/threonine kinase Pelle and adaptor protein Tube through their N-terminal death domains leads to the nuclear translocation of the transcription factor Dorsal and activation of zygotic patterning genes during Drosophila embryogenesis. Crystal structure of the Pelle and Tube death domain heterodimer reveals that the two death domains adopt a six-helix bundle fold and ...

Rayleigh scattering spectra and Raman spectra from single bundles of aligned single-wall carbon nanotubes (SWNTs) have been obtained with dark field optical microscopy and Raman microscopy. Rayleigh scattering spectrum reveals resonance peaks due to the optically allowed interband transitions in SWNTs. The intensity of the resonance peaks was found to depend strongly on the incident light polar...
