Effects of alfalfa-intercropping and nanosilver-impregnation were studied here on the specific gas permeability of 10-year old Populus nigra var. betulifolia. Specimens were impregnated with a 200 ppm aqueous dispersion of silver nanoparticles under 250 kPa pressure; the results were then compared with the un-impregnated specimens. The size range of silver nanoparticles was 10 to 80 nm. After t...

Objective: Analyze the effect of sugar substitution by dehydrated aguamiel on physicochemical quality pear jam (Pyrus communis L.) 
 Design/methodology/approach: Different levels were analyzed (0, 25 and 50%). Physicochemical parameters as color, pH, acidity, density, consistency soluble solids evaluated.
 Results: Results showed that color characteristics was changed Study limitation...
