Diffusion phenomena of the oxygen and nitrogen in niobium by mechanical spectroscopy
(2010-05-19)
The short-range diffusion phenomenon (Snoek Effect) was investigated by mechanical spectroscopy measurements between 300 K and 650 K, in a polycrystalline niobium sample, containing oxygen and nitrogen, using a torsion ...
Comparison between Lebaron-Perez and Dal Pai-Escobedo correction methods for diffuse irradiance measured by the meo shadowring method
(2017-01-01)
This study aims to determine the effectiveness of two methods of correction of diffuse irradiance measured with shadowbands: LeBaron-Perez method and Dal Pai-Escobedo method. For the LeBaron-Perez method, we use the original ...
Possible indirect measurement of diffusion coefficient from migration kinetic essay of food packaging
(2008-01-01)
Diffusion coefficient is an important quantity that affects any migration process on food or nutritional systems. Special care has to be done to migration of undesirable substances from packaging into foods, if the diffusion ...
Salting kinetics, salt diffusivities and proximate composition in osmotically dehydrated Pirarucu muscle
(Univ Politecnica Valencia, 2018-01-01)
Pirarucu (Arapaima gigas Schinz) farming has been encouraged and, among meat preservation techniques, the salting process is a relatively simple and low-cost method. The objective of this work was to study the sodium ...
Diffusion analysis of one photosensitizer in bovine teeth using fluorescence optical imaging
(Spie - Int Soc Optical Engineering, 2012-01-01)
Some photosensitizers (PSs) used for PACT (Antimicrobial Photodynamic Therapy) show an affinity for bacterial walls and can be photo-activated to cause the desired damage. However, on dentine bacterias may be less susceptible ...

(Trans Tech Publications Ltd, 2008-01-01)
The scientific and technological development in the area of new materials contributed to several applications of niobium and its alloys in nuclear power plants as well as in aerospace, aeronautics, automobile and naval ...
Oxygen Diffusion in Ti-20Mo Alloys, used as Biomaterial, Measured by Mechanical Spectroscopy
(Trans Tech Publications Ltd, 2012-01-01)
Titanium alloys are favorable implant materials for orthopedic applications, due to their desirable properties such as good corrosion resistance, low elasticity modulus, and excellent biocornpatibility. The research on ...
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 ...
Diffusion of Interstitial Elements in Ti Alloys used as Biomaterials
(Trans Tech Publications Ltd, 2009-01-01)
Titanium alloys are excellent implant materials for orthopedic applications due to their desirable properties, such as good corrosion resistance, low elasticity modulus, and excellent biocompatibility. The presence of ...
Diffusion of Nitrogen in Ti-13V-11Cr-3Al Alloys
(Trans Tech Publications Ltd, 2009-01-01)
Metals with a bcc crystalline structure such as Ti-13V-11Cr-3Al alloys have their physical properties significantly changed through the addition of interstitial elements such as oxygen and nitrogen. These metals can dissolve ...
