25. Influence of upward and horizontal growth direction on microstructure and microhardness of an unsteady-state directionally solidified Al-Cu-Si alloy
In order to analyze the effect of the growth direction on dendrite arm spacing (λ1) and microhardness (HV) during horizontal directional solidification (HDS), experiments were carried out with the Al-3wt.%Cu-5.5wt.%Si alloy and the results compared with others from the literature elaborated for upward directional solidification (UDS). For this purpose, a wa

26. The Effect of Material Property on the Critical Velocity of Randomly Excited Nonlinear Axially Travelling Functionally Graded Plates
Abstract In this paper, the critical axial speeds of three types of sigmoid, power law and exponential law functionally graded plates for both isotropic and orthotropic cases are obtained via a completely analytic method. The plates are subjected to lateral white noise excitation and show evidence of large deformations. Due to randomness, the conventional de

27. Research on Free Vibration Frequency Characteristics of Rotating Functionally Graded Material Truncated Conical Shells with Eccentric Functionally Graded Material Stringer and Ring Stiffeners
Abstract In this research work, an exact analytical solution for frequency characteristics of the free vibration of rotating functionally graded material (FGM) truncated conical shells reinforced by eccentric FGM stringers and rings has been investigated by the displacement function method. Material properties of shell and stiffeners are assumed to be graded

28. Free vibration responses of temperature dependent functionally graded curved panels under thermal environment
Abstract Free vibration responses of shear deformable functionally graded single/doubly curved panels under uniform, linear and nonlinear temperature fields are investigated in the present article. The micromechanical material model of functionally graded material is computed using Voigt model in conjunction with the power-law distribution to achieve the con

29. 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

30. Fracture initiation from initial spherical flaws in incompressible propellant materials
The scope of the present article is the study of the fracture initiation from initial spherical flaws in incompressible propellant materials. Using a constitutive law, derived from the neo-Hookean strain energy function, one may deduce the relation between the radial pressure applied at infinity and the corresponding extension ratio, at the surface of the ca

31. Error propagation in open respirometric assays
This work deals with the calculation of the uncertainty of the exogenous respiration rate (Rex) and the total oxygen consumed (OCT) derived from a single open respirometric profile. Uncertainties were evaluated by applying a linear error propagation method. Results show that standard deviations (SD) of Rex and OCT depend not only on the SD of the dissolved o

32. Dynamic and static analysis of FGM skew plates with 3D elasticity based graded finite element modeling
The present article deals with static and dynamic behavior of functionally graded skew plates based on the three-dimensional theory of elasticity. On the basis of the principle of minimum potential energy and the Rayleigh Ritz method, the equations of motion are derived in conjunction with the graded finite element approach. Solution of the resulted system o

33. Size-dependent vibrations of post-buckled functionally graded Mindlin rectangular microplates
In this paper, the free vibration behavior of post-buckled functionally graded (FG) Mindlin rectangular microplates are described based on the modified couple stress theory (MCST). This theory enables the consideration of the size-effect through introducing material length scale parameters. The FG microplates made of a mixture of metal and ceramic are consid

34. Inactivation of Bacillus atrophaeus spores in healthcare waste by uv light coupled with H2O2
Healthcare waste inoculated with B. atropheaus spores was used to evaluate a treatment process using UV light in combination with H2O2. First, the influence of the waste mass on the spore inactivation fraction was investigated for a constant radiation exposure time of 10 min and power per unit mass of waste (44-237 W/kg). The degree of inactivation of the sp

35. Os limites do direito diante da teoria do risco: uma abordagem sobre a (in)eficiência das políticas de segurança pública
Os estudos sobre a Teoria da Sociedade, desenvolvidos de forma originária por Niklas Luhmann identificam que a função do Direito na atual sociedade passa a ser de não limitar o Direito e sua ação, pelo contrário, ela busca superar a forma tradicional e delimitada do exercício da ação do direito, contribuindo, assim para abrir quanto mais espaços p

36. As limitações aos direitos fundamentais: os limites dos limites como instrumento de proteção a estes direitos
The promulgation of the Constitution of 1988 inserted Brazil into the Democratic Rule-of- Law State paradigm. Thenceforth, fundamental rights play an important role in the legal structure as central norms in the constitutional system. Due to this new function, a closer study of this subject is required not only by scholars but also by decision makers respons
