During the first several minutes of an explosive volcanic eruption, the flow in the column above the vent is unsteady even if the discharge from the vent is steady. At a fixed location in the column, parameters such as temperature and ash content change with time until steady flow conditions are established. For conditions believed to be typical of fountain-forming silicic eruptions of intermed...

The objective of this paper was to fabricate a biodegradable tubular scaffold for small diameter (d<6 mm) blood vessel tissue engineering. The tube scaffold needed a porous wall for cell attachment, proliferation and tissue regeneration with its degradation. A novel method given in this paper was to coat a porous layer of poly (epsilon-caprolactone) (PCL) on the outside of a poly (glycolic-co-l...

Depth-from-Defocus (DFD) using the Spatial-Domain Convolution/Deconvolution Transform Method (STM) is a useful technique for 3D vision. STM involves simple local operations in the spatial domain on only two images recorded with diierent camera parameters (e.g. by changing lens position or changing aperture diameter). In this paper we provide a theoretical treatment of the noise sensitivity anal...

In the operations of banana postharvesting process, design and development related to dehanding machine, cutting crushing machine bunch stalks, fiber extraction stalks are in initial stages. addition, with society urbanization, aging populations hilly mountainous areas, where bananas planted, becoming a more serious problem. The basic physical characteristic parameters bunches, hands, basis for...

Hydroxyapatite (HAp) nanoparticles of tunable diameter were obtained by the precipitation method at room temperature and by microwave hydrothermal synthesis (MHS). The following parameters of the obtained nanostructured HAp were determined: pycnometric density, specific surface area, phase purity, lattice parameters, particle size, particle size distribution, water content, and structure. HAp n...

ISSN 2277 – 5056 | © 2012 Bonfring Abstract--A FEM simulation study was carried out to investigate the influence of the rolling parameters on the rolling process. Using commercial FEM software, ABAQUS, a number of cases were studied. In this paper, a twodimensional Elastic-plastic finite element model to simulate the cold rolling of thick strip with different roll angular velocity and roll diam...

The morphology of filamentous fungi closely correlates with the productivity in submerged culture. Using itaconic acid (IA) production by Aspergillus terreus as a research model, the quantitative relationship between the growth form of A. terreus and IA production was investigated. IA fermentation was scaled up from shake flasks to a 7 L stirred tank bioreactor based on the quantitative relatio...

We demonstrated gate voltage control of spin precession in InGaAs mesoscopic ring arrays based on Rashba spin orbit interaction (SOI). We employed 100 nm ALD Al2O3 and 150 nm sputtered SiO2 gate insulators combined with large and small ring arrays to compare the gate sensitivity for the spin precession. Al’tshuler-Aronov-Spivak (AAS) oscillations were clearly observed and the oscillation phases...
