1. RECENT ADVANCES IN CYANATION REACTIONS
Transformations involving structurally complex molecules, natural products and representative molecules are extremely important to obtain key reaction intermediates, in addition to accessing molecules with bioactive properties. The development of cyanation methodologies in those molecules becomes important, because nitriles are versatile and important buildi

2. Large Displacement Static Analysis of Composite Elliptic Panels of Revolution having Variable Thickness and Resting on Winkler-Pasternak Elastic Foundation
Abstract Nonlinear static response of laminated composite Elliptic Panels of Revolution Structure(s) (EPRS) having variable thickness resting on Winkler-Pasternak (W-P) Elastic Foundation is investigated in this article. Generalized Differential Quadrature (GDQ) method is utilized to obtain the numerical solution of EPRS. The first-order shear deformation th

3. Turbo-extraction of glycosides from Stevia rebaudiana using a fractional factorial design
ABSTRACT Stevia rebaudiana (Bertoni) Bertoni, Asteraceae, leaf extract has recently called the attention of food industry as a proposal for natural sweetener. The sweet flavor is attributed to the glycosides, in especial stevioside and rebaudioside A, which are the plant main chemical markers. The aim of the work reported here was to optimize the turbo-extra

4. Propagation of plane waves at the interface of an elastic solid half-space and a microstretch thermoelastic diffusion solid half-space
The problem of reflection and refraction phenomenon due to plane waves incident obliquely at a plane interface between uniform elastic solid half-space and microstretch thermoelastic diffusion solid half-space has been studied. It is found that the amplitude ratios of various reflected and refracted waves are functions of angle of incidence, frequency of inc

5. Chromatic spatial contrast sensitivity estimated by visual evoked cortical potential and psychophysics
The purpose of the present study was to measure contrast sensitivity to equiluminant gratings using steady-state visual evoked cortical potential (ssVECP) and psychophysics. Six healthy volunteers were evaluated with ssVECPs and psychophysics. The visual stimuli were red-green or blue-yellow horizontal sinusoidal gratings, 5° × 5°, 34.3 cd/m2 mean luminan

6. Vibration of flexible and rigid plates on transversely isotropic layered media = : Vibração de placas flexíveis e rígidas em meios estratificados transversalmente isotrópicos / Vibração de placas flexíveis e rígidas em meios estratificados transversalmente isotrópicos
Este trabalho apresenta novos modelos para descrever o comportamento harmônico de placas rígidas e flexíveis incrustadas em meios estratificados. Incrustações profundas das placas são representadas por interfaces bi-materiais de meios viscoelásticos transversalmente isotrópicos. Incrustações rasas são representadas por meios estratificados viscoel

7. Análise e planejamento da floresta urbana enquanto elemento da infraestrutura verde: estudo aplicado à Bacia do Córrego Judas / Maria Joaquina, São Paulo / Analysis and planning of the urban forest as part of the green Infrastructure: study applied to the watershed of the Stream Judas / Maria Joaquina at São Paulo City, Brazil.
This dissertation develops a design proposal of the Green Infrastructure of the São Judas / Maria Joaquina\ s stream watershed, as a way to promote the increase of the tree cover, and of the public green spaces as well as the connectivity between areas that provide ecosystem services. A study of the Urban Forest - the main component of the Green Infrastruct

8. Solution of hyperbolic bioheat transfer problems by numerical green's functions: the ExGA-linear θ method
This paper presents a time-domain formulation called Explicit Green's approach (ExGA) linear θ method for the solution of the bioheat equation. Starting from the hyperbolic bioheat equation, which includes the parabolic one as a special case, the linear method is incorporated into the standard ExGA time marching scheme. The numerical Green's function is fir

9. Planar multilayer structure analysis: an educational approach
This paper discusses how symbolic computation combined with a circuit model can be used for analyzing planar multilayer structures, in a manner suitable for educational approach. Working in the Fourier domain, expressions for the transversal spectral Green’s functions are evaluated in compact, closed form using the symbolic computation capability of the Ma

10. Métodos Monte Carlo Quântico e Outer Valence Green s function aplicados na obtenção de energias de ionização de sistemas atômicos e moleculares e na construção e interpretação de diagramas de correlação / Quantum Monte Carlo and Outer Valence Green s function methods applied to obtain ionization energies of atomic and molecular systems and to construction and interpretation of correlation diagrams
The study was divided into 4 parts: Simple Ionization Energies: We evaluated the ability of MQC and OVGF methods in describing the values of the ionization energy of valence and core and tested the use of relaxed wave functions. The range of deviations obtained with the method of diffusion quantum Monte Carlo (MCQD), in relation to the experimental values, i

11. DinÃmica de VÃrtices pontuais na esfera S2 e no espaÃo hiperbÃlico
We present the movement equations of n punctual vortices over the following Riemann surfaces: the sphere S2 and the hyperbolic space H2. We also state the Hamiltonian formulation of the vortices motion over these surfaces. For this purpose, we primarily present the stereographic projection over S2 and over H2. Then, we construct the Laplace-Beltrami operator

Relação entre diversidade arbórea e aspectos do ciclo biogeoquímico de uma floresta monodominante de Brosimum Rubescens Taub. e uma floresta mista no Leste Mato-Grossense / Relação entre diversidade arbórea e aspectos do ciclo biogeoquímico de uma floresta monodominante de Brosimum Rubescens Taub. e uma floresta mista no Leste Mato-Grossense
Tropical monodominant forests in which one species represents more than 50% of the above ground biomass are a rare vegetation type. One of these forests is found in the eastern region of the State of Mato Grosso where the tree species Brosimum rubescens Taub. (Moraceae), accounts for more than 80% of the above ground biomass of the forest community. This sit
