1. USO DE UM SCANNER DE MESA E ESPUMA DE POLIURETANO PARA QUANTIFICAÇÃO DE FERRO TOTAL EM CÁPSULAS DE SUPLEMENTOS ALIMENTARES
In this work, an alternative and low-cost technique for the extraction and quantification of Fe (total) from food supplements by digital image analysis is shown. The method is based on the complexation of Fe ions in solution with the 8-hydroxyquinoline ligand, forming a colored complex that is extractable from aqueous solution to polyurethane foam, coloring

2. SPRAY DEPOSITION ON MAIZE USING AN ELECTROSTATIC SPRAYER
ABSTRACT It is a well-known fact that the application of pesticides can be improved using an electrostatic spray due to the reduction of the application rate and increase in deposition on plant targets. However, little information exists on the use of such technology in maize crops. Thus, this study is aimed to evaluate the spray deposition on maize resultin

3. GPU Finite Element Method Computation Strategy Without Mesh Coloring
Abstract A GPU-adapted Finite Element Method (A-FEM) implementation without using a mesh coloring strategy to avoid race conditions is presented. All the elements are simultaneously processed, and the local data is computed and consolidated into the device memory in a new adapted Coordinate Format data structure (a-COO). The comparison between the proposed s

4. Analytical study of the physicochemical characteristics from Melipona subnitida D. honey in adequation to Brazilian law
Abstract Honey has different physical and chemical properties because it is produced from the nectar of plants. The present work had the objective of analyzing laboratory tests on honey bee Melipona subnitida D. from Ceará, in comparing them with other honeys from the Northeast Region, making it possible to know better the standards of these honeys, in orde

6. Plasma Treatment of Polyamide Fabric Surface by Hybrid Corona-Dielectric Barrier Discharge: Material Characterization and Dyeing/Washing Processes
In this study, the hybrid corona-dielectric barrier discharge plasma treatment was employed to modify the physical, chemical and morphological characteristics of a half-knitted fabric composed of 92% polyamide 6.6 and 8% elastane (PA). These properties of the fabric were evaluated by the water contact angle, x-ray diffraction, infrared spectroscopy, scanning

7. Monochromatic double coloring effect on V2O5 thin films deposited by electron beam
ABSTRACT Electrochromic material is a thin film technology that has a close relationship with environmental sustainability since they can control the light and heat that enter and leave a building. Vanadium oxide films are electrochemically active for lithium and electron co-intercalation, presenting low optical variation in the low energy visible light, whi

11. Effects of Curcuma longa rhizome on growth, skin pigmentation, and stress tolerance after transport of Trichogaster labiosa
ABSTRACT We aimed to evaluate the effects of Curcuma longa as growth promoter, skin pigmentation enhancer, and stress reducer in diets of Trichogaster labiosa after transport. We used five diets containing 0.0, 1.0, 5.0, 10.0, and 25.0 g kg−1 of turmeric rhizome powder. We observed quadratic effects of turmeric supplementation for feed intake, weight gain,

12. Morpho and Cytological Differentiation of Calli of Eucalyptus grandis x Eucalyptus urophylla During Somatic Embryogenesis
ABSTRACT The aim of this study was to induce and analyze embryogenic calli from two types of explants (leaves and meristems) of the hybrid Eucalyptus grandis x Eucalyptus urophylla. Leaves and meristems of plants kept in a nursery were disinfected and inoculated in Petri dishes containing MS culture medium supplemented with different concentrations of the gr
