Previous research has indicated a qualitative resemblance between the current distribution along actively corroding crevice walls and currents measured in corresponding anodic polarization plots. Using detailed measurements of the potential gradient along the crevice, a semi-quantitative current distribution was calculated for the crevice wall using a double numerical differentiation method. Th...

This paper provides a summary analysis of the typological and historical development of active glass walls. From the beginning of the glass revolution, the fascination with large areas of transparency has been tempered by the negative environmental effects they can produce: excessive heat loss when it is cold, excessive heat gain when the sun shines, and even excessive daylighting. Comments Pre...

the effective parameters of (5, 0) and (5, 5) single-wall carbon nanotubes during the interaction with carbon dioxide as sensors are determined. the interaction of carbon dioxide  molecules with internal and external walls of the nanotubes is studied using gaussian 03 coding by density functional theory (dft) at the b3lyp/6-311g level of theory. co2 rotation around tube axles vertically and par...

In this paper, Homotopy perturbation method (HPM) has been applied to investigate the effect of magnetic field on Cu-water nanofluid flow in non-parallel walls. The validity of HPM solutions were verified by comparing with numerical results obtained using a fourth order Runge–Kutta method. Effects of active parameters on flow have been presented graphically. The results show that velocity i...

Lysobacter enzymogenes strain N4-7 produces multiple biochemically distinct extracellular -1,3-glucanase activities. The gluA, gluB, and gluC genes, encoding enzymes with -1,3-glucanase activity, were identified by a reverse-genetics approach following internal amino acid sequence determination of -1,3-glucanase-active proteins partially purified from culture filtrates of strain N4-7. Analysis ...

Lysobacter enzymogenes strain N4-7 produces multiple biochemically distinct extracellular beta-1,3-glucanase activities. The gluA, gluB, and gluC genes, encoding enzymes with beta-1,3-glucanase activity, were identified by a reverse-genetics approach following internal amino acid sequence determination of beta-1,3-glucanase-active proteins partially purified from culture filtrates of strain N4-...

abstract: Although structures have been built from masonry for many years, little is still known about the behaviour of a wall subject to in-plane shear. This particularly true partially grouted concrete masonry. The factors that are affect strength this type discussed with varying results and interpretations highlighted. There consensus increasing axial stress increases shear reduces ductility...
