13. Vibration Analysis of Rotating Functionally Graded Cylindrical Shells with Orthogonal Stiffeners
Abstract In this paper, free vibration analysis of rotating functionally graded cylindrical shells with orthogonal stiffeners is presented. Based on Love's first approximation theory and smeared stiffeners technique, the governing equations of motion which take into account the effects of initial hoop tension and also the centrifugal and Coriolis forces due

14. Génesis Semiótica de los Enteros
Abstract The traditional presentation of the integers ring generates difficulties for learning the product with its well-known signs rule. Our working hypothesis is that the solely representation of the product of two natural numbers by the area of a rectangle can hinder the vision of the product of two integers. Referring us to the scheme of Mathematical Wo

15. Vibration and Buckling Analysis of Functionally Graded Plates Using New Eight-Unknown Higher Order Shear Deformation Theory
Abstract In this paper a new eight-unknown higher order shear deformation theory is proposed to study the buckling and free vibration of functionally graded (FG) material plates. The theory bases on full twelve-unknown higher order shear deformation theory, simultaneously satisfies zero transverse shear stress at the top and bottom surfaces of FG plates. Equ

16. Dynamic analysis and vibration control of a multi-body system using MSC Adams
AbstractIn this paper, modelling and simulation of a multi-body system for its vibration control using sensors and actuators is presented. The model developed on MSC ADAMS consists of six legs connecting moving and base plates using spherical joints with axial rotation of legs constrained. It contains linear actuator collocated with force sensor. Mathematica

17. Semi-analytical Vibration Characteristics of Rotating Timoshenko Beams Made of Functionally Graded Materials
AbstractFree vibration analysis of rotating functionally graded (FG) thick Timoshenko beams is presented. The material properties of FG beam vary along the thickness direction of the constituents according to power law model. Governing equations are derived through Hamilton's principle and they are solved applying differential transform method. The good agre

18. Three dimensional Free Vibration and Transient Analysis of Two Directional Functionally Graded Thick Cylindrical Panels Under Impact Loading
AbstractIn this paper three dimensional free vibration and transient response of a cylindrical panel made of two directional functionally graded materials (2D-FGMs) based on three dimensional equations of elasticity and subjected to internal impact loading is considered. Material properties vary through both radial and axial directions continuously. The 3D g

19. DISPOSITIVOS DGT MODIFICADOS COM MATERIAIS ALTERNATIVOS PARA USO NA ESPECIAÇÃO DE ELEMENTOS TRAÇO
The use of MT-K10 Montmorillonite immobilized onto agarose was investigated in this work as an alternative binding phase in Diffusive Gradient in Thin Film (DGT) devices for the determination of metallic labile species. In addition, agarose itself was also used as the diffusive phase. The percentage of sorption of Zn2+, Cu2+, Cr3+, Mn2+, Cd2+, Pb2+, and Ni2+

20. Strategies to improve the mechanical properties of starch-based materials: plasticization and natural fibers reinforcement
Biodegradable polymers are starting to be introduced as raw materials in the food-packaging market. Nevertheless, their price is very high. Starch, a fully biodegradable and bioderived polymer is a very interesting alternative due to its very low price. However, the use of starch as the polymer matrix for the production of rigid food packaging, such as trays

21. Luis de León (1527-1591) y su teoría de la justicia: aspectos principales de su doctrina
The studies about Luis de León has focused mainly in his mystical, narrative and literary theory. In this paper, the author attempts to develop the principal aspects of his legal doctrine. Like other great theologians of The Salamanca School, also Leon has studied the issue of the nature of human law and its relationship with the natural law. This is precis

22. Whole transcriptome organisation in the dehydrated supraoptic nucleus
The supraoptic nucleus (SON) is part of the central osmotic circuitry that synthesises the hormone vasopressin (Avp) and transports it to terminals in the posterior lobe of the pituitary. Following osmotic stress such as dehydration, this tissue undergoes morphological, electrical and transcriptional changes to facilitate the appropriate regulation and relea

23. El derecho positivo o convencional, su naturaleza: el carácter creativo (constitutivo) y derivado de las leyes humanas
This paper attempts to present some criteria for recognizing a rule of positive law. Even thoughit is true that the classical iusnaturalism teaches that the legal norms contains natural and conventional elements, it is possible, I think, recognize that a rule belongs, strictly speaking, at the positive law or natural law. In particular, I propose that a rule

24. A importância da lei de Gay-Lussac para a classificação dos compostos orgânicos
This article shows the genesis of the law of volumes of combining gases, formulated by Gay-Lussac in 1808, and how it allowed the expression of the composition of organic compounds in terms of whole numbers of volumes, thus leading to the first classification of organic compounds, formulated by Dumas and Boullay in 1828. It was from this work that Organic Ch
