1. Design and Performance Study of Single and Multi-Layered Fractal Based Miniaturized Patch Antennas for 2.4 GHz Applications
Abstract The design and characterization of single and multi-layered miniaturized microstrip antennas resonating at 2.4 GHz are proposed. The miniaturization is accomplished by fractal Defected Ground Structure (DGS). The DGS used for miniaturization is a Modified Minkowski Fractal DGS (M-MFDGS). The proposed size reduction process with M-MFDGS follows the s

5. El análisis de imágenes como herramienta de monitoreo en la deshidratación de rodajas de banana
Abstract The objective of this work was to evaluate the morphometric, fractal and color changes during the dehydration of banana slices through the use of image analysis. The convective drying was performed between 75 °C and 134 °C at an air velocity of 0.65 m s-1. Results showed that the images provided quantitative information of the morphometric changes

10. Models for leaf area estimation in dwarf pigeon pea by leaf dimensions
ABSTRACT This study aims to determine the most suitable model to estimate the leaf area of dwarf pigeon pea in function of the leaf central leaflet dimension. Six samplings of 200 leaves were performed in the first experiment, at 36, 42, 50, 56, 64, and 72 days after emergence (DAE). In the second experiment, seven samplings of 200 leaves were performed at 2

11. A cytotoxic Petiveria alliacea dry extract induces ATP depletion and decreases β-F1-ATPase expression in breast cancer cells and promotes survival in tumor-bearing mice
Abstract Metabolic plasticity in cancer cells assures cell survival and cell proliferation under variable levels of oxygen and nutrients. Therefore, new anticancer treatments endeavor to target such plasticity by modifying main metabolic pathways as glycolysis or oxidative phosphorylation. In American traditional medicine Petiveria alliacea L., Phytolaccacea
