Abstract: Obesity is a public health problem and its prevalence increases every year, resulting from a complex interaction between genetic, metabolic and environmental factors, as well as cultural influences. The Intestinal Microbiota is composed of trillions of microorganisms by forming a symbiotic relationship with the host and helping the absorption of various nutrients, increasing the extraction of components of the diet, the lipogenesis and intestinal permeability. Studies show that there is difference between the composition of the intestinal microbiota of an obese person and a healthy one. The purpose of this article is to review the literature on the relationship between the Intestinal Microbiota, Obesity and Insulin Resistance and also illustrate some studies on the subject.

Abstract: This paper presents the validation of a computational tool that serves to obtain continuous measurements of moving objects. The software uses techniques of computer vision, pattern recognition and optical flow, to enable tracking of objects in videos, generating data trajectory, velocity, acceleration and angular movement. The program was applied to track a ball around a simple pendulum. The methodology used to validate it, taking as a basis to compare the values measured by the program, as well as the theoretical values expected according to the model of a simple pendulum. The experiment is appropriate to the method because it was built within the limits of the linear harmonic oscillator and energy losses due to friction had been minimized, making it the most ideal possible. The results indicate that the tool is sensitive and accurate. Deviations of less than a millimeter to the extent of the trajectory, ensures the applicability of the software on physics, whether in research or in teaching topics.
