1. Seed quality of 22 quinoa materials (Chenopodium quinoa Willd.) from the department of Boyacá
ABSTRACT Chenopodium quinoa Willd. is a pseudocereal with seeds that are a rich source of vitamins and minerals. However, there are few studies on quinoa seed quality, especially for the Colombian germplasm. So, the objective of this research was to determine the quality of 22 quinoa materials from the Department of Boyacá by evaluating the physical (color,

8. Characterization of growth sectors in synthetic quartz grown from cylindrical seeds parallel to [0001] direction
In the present study, the morphology and the impurity distribution were investigated in growth sectors formed around the [0001] axis of synthetic quartz crystals. Plates containing cylindrical holes and cylindrical bars parallel to [0001] were prepared by ultrasonic machining and further used as seed-crystals. The hydrothermal growth of synthetic quartz was

10. Estudo de um secador com promotores estaticos anulares de mistura
A Continuous Vertical Annular Static Mixer Dryer was constructed and studied (Industrial Patent 8700583). The equipment consisted on a cylindrical drying column constructed in transparent acrylics, and a fan that blowed the ambient air, which was heated by a set of electrical heaters. The air flow rate was controlled by changing the admission area of the fan
