Drying of persimmon: Mathematical model for diffusivity as a simultaneous function of moisture content and shrinkage
(Isnt Tecnologico Veracruz, 2001-01-01)
Fresh persimmon has a high moisture content (about 85% wet basis) making it highly perishable and requiring adequate drying conditions to obtain an acceptable dehydrated product. Drying kinetics of persimmon cv. Rama Forte ...
Rehydration and shrinkage behaviour of dried pineapple
(Isnt Tecnologico Veracruz, 2001-01-01)
The shrinking behavior, apparent densities and rehydration indexes of fresh and osmotically pre-treated pineapple slices during air-drying were obtained. The air drying velocity varied from 1.5 to 2.5 m/s and the air ...
Modeling and simulation of intermittent drying of high moisture foods
(Univ Politecnica Valencia, 2018-01-01)
This study aimed at the modeling and simulation of intermittent drying to be applied to highly deformable moist foods such as apples. Mass transport modeling considered two stages: the first at 95, 85 and 75 degrees C air ...
Influence of chomium and molybdenum in solidification and shrinkage defects for high resistance grey iron alloys
(Instituto de Investigaciones en Ciencia y Tecnolog a de Materiales (INTEMA)Mar del Plata, 2014-11-10)
This paper presents an evaluation of Cr and Mo influence in solidification and shrinkage defects in grey cast iron. A series of five grey cast irons were produced with different Cr and Mo additions. A test casting was ...
Multipath reduction from GPS double differences using wavelets: How far can we go?
(2004-12-01)
Wavelets are being extensively used in Geodetic applications. In this paper, the Multi-Resolution Analysis (MRA) using wavelets is applied to pseudorange and carrier phase GPS double differences (DDs) in order to reduce ...
Sintering of ZnO doped SnO2
(Kluwer Academic/plenum Publ, 1999-01-01)
Dense SnO2 ceramics were obtained by doping with ZnO concentrations varies from 0.5 to 5.0 mel. The obtained powder was isostaticaly pressed to 210MPa in cylindrical shape and sintered from ambient to 1.500 degrees C using ...
Electrical measurements in doped zirconia-ceria ceramics
(Amer Ceramic Soc, 2002-01-01)
Zirconia-ceria powders with 12 mol % of CeO2 doped with 0.3 mol% of iron, copper, manganese and nickel oxides were synthesized by the conventional mixed oxide method. These systems were investigated with regard to the ...
A regularized nonlinear diffusion approach for texture image denoising
(2009-12-01)
In this paper a new partial differential equation based method is presented with a view to denoising images having textures. The proposed model combines a nonlinear anisotropic diffusion filter with recent harmonic analysis ...
Effect of the incorporation of marble waste in the properties of clay ceramic bricks
(2020-01-01)
Residues incorporation into construction building materials is a promising sustainable alternative for the correct disposal of this kind of material. Brazil is one of the largest world producers of ornamental stones. ...
