Analysis of Operating Conditions on Osmotic Dehydration of Plums (Prunus Domestica L.) and 3D-Numerical Determination of Effective Diffusion Coefficients
(De Gruyter, 2017-11)
The objective of this work was to analyze the relevant process conditions on osmotic dehydration of plums and to determine the diffusion coefficients related to this process. The influence of solution (type and concentration ...
Temperature-dependent diffusion coefficient of oil from different sunflower seeds during extraction with hexane
(Elsevier, 2011-07-17)
Oil extraction from confectionery, oilseed and wild sunflower seeds with n-hexane was investigated by laboratory tests carried out in a stirred batch extractor at several temperatures (40, 50 and 60 °C). The rates of ...
Charm diffusion in a pion gas implementing unitarity, chiral and heavy quark symmetries
(2011)
We compute the charm drag and diffusion coefficients in a hot pion gas, such as is formed in a heavy ion collision after the
system cools sufficiently to transit into the hadron phase. We fully exploit heavy quark effective ...
Effective diffusion coefficients behavior in osmotic dehydration of apple slices considering shrinking and local concentration dependence
(Blackwell Publishing, 2008-04-01)
The mass transfer during osmotic dehydration of apple slices immersed in 40, 50 and 60% (w/w) aqueous sucrose solutions was investigated to evaluate the influence of solution concentration on diffusivities. In the mathematical ...

Messages Do Diffuse Faster Than Messengers: Reconciling disparate estimates of the morphogen Bicoid diffusion coefficient
(Public Library Of Science, 2014-04)
The gradient of Bicoid (Bcd) is key for the establishment of the anterior-posterior axis in Drosophila embryos. The gradient properties are compatible with the SDD model in which Bcd is synthesized at the anterior pole and ...
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 ...
