3. Use of stable isotopes of carbon to detect coconut water adulteration
ABSTRACT: Industrialized coconut water may have been adulterated by adding sugar above the limit permitted by law. According to Brazilian law, industrialized coconut water can receive the maximum addition of 1 g of sugar per 100 mL of the drink. This work aimed to detect adulteration in industrialized coconut water produced in Brazil and measure the relative

4. Elastoplastic Stability and Failure Analysis of FGM Plate with Temperature Dependent Material Properties under Thermomechanical Loading
Abstract The present paper explores the stability and failure response of elastoplastic Ni/Al2O3 functionally graded plate under thermomechanical load using non-linear finite element formulation based on first-order shear deformation theory and von-Karman’s nonlinear kinematics. The temperature dependent thermoelastic material properties of FGM plate are v

5. DESENVOLVIMENTO DE UMA TÉCNICA ULTRASSÔNICA PARA AVALIAR TEORES DE ÓLEO E GRAXA EM EFLUENTES DE BIOCOMBUSTÍVEIS
Ultrasound as a metrology tool has many applications in health care, industrial, and chemical analyses. Ultrasonic techniques are rapid, low-cost, non-invasive, and highly repeatable. Although ultrasound can be used to measure emulsions, no effort had been made thus far to optimize its sensitivity for metrological analysis. In this work, a technique for anal

6. A universal constant for semistable limit cycles
We consider one-parameter families of 2-dimensional vector fields Xµ having in a convenient region R a semistable limit cycle of multiplicity 2m when µ = 0, no limit cycles if µ < 0, and two limit cycles one stable and the other unstable if µ > 0. We show, analytically for some particular families and numerically for others, that associated to the semist

7. Composição do leite e diagnóstico de mastite em caprinos) = Milk composition and mastitis diagnosis in goats / Milk composition and mastitis diagnosis in goats
Background: Milk is one of the most used foodstuffs by humans in their diet. The quality of goat milk is already regulated by Law, which takes into consideration its physical-chemical and microbiological composition parameters. Several factors contribute for the alteration of the physical-chemical and microbiological parameters of caprine milk. These include

8. Development and validation of spectrophotometric method for the determination of DPP-4 inhibitor, sitagliptin, in its pharmaceutical preparations
A simple, sensitive and reproducible spectrophotometric method was developed for the determination of sitagliptin phosphate in bulk and in pharmaceutical formulations. The proposed method is based on condensation of the primary amino group of sitagliptin phosphate with acetyl acetone and formaldehyde producing a yellow colored product, which is measured spec

9. PROPRIEDADES VIBRACIONAIS E DIELÉTRICAS DA MULITA Bi2Mn4O10 / VIBRATIONAL PROPERTIES AND DIELECTRIC OF MULITA Bi2Mn4O10
In this work we investigated the vibrational properties of ceramics Bi2Mn4O10 (BMO) at room temperature by the Raman and Infrared spectroscopies, the phonons were classified by FG matrix method of Wilson. The dielectric properties of the material, in turn, were studied using the impedance spectroscopy in a range of 22 C to 275 C. Furthermore, static atomisti

12. Controle de movimentos coordenados de robôs móveis quando os robôs assumem a liderança de maneira aleatória / Control of coordinated movements of mobile robots when the robots take the lead in a random
This dissertation proposes a study on the automatic control of dynamic systems to the problem of coordination of mobile robots. The coordinated motions are performed with the robots following a leader, and any robot of the formation can assume the leadership randomly. The robots exchange informations according to a pre-specified communication directed graph
