1. Imiquimod/β-Cyclodextrin Inclusion Complex: Experimental and Theoretical Studies
Imiquimod (IMQ), an immune response modifier, is used for topical treatment of basal cell carcinoma and actinic keratosis. The very poor aqueous solubility of imiquimod gives rise to difficulties in designing aqueous formulations with this drug. One approach that is widely used to enhance drug solubility is complexation with cyclodextrins. The formation of t

2. Inelastic second-order analysis of steel columns under minor-axis bending
Abstract The inelastic second-order behavior of steel structural columns under minor-axis bending is presented in this article. To study this behavior, a nonlinear frame element formulation is adopted in which the steel's plasticity process is accompanied at the nodal points of each finite element through the refined plastic-hinge method (RPHM). A tangent mo

3. Cytotoxicity, antioxidant and antibacterial activity of four compounds produced by an endophytic fungus Epicoccum nigrum associated with Entada abyssinica
ABSTRACT Four compounds including beauvericin, parahydroxybenzaldehyde, indole-3-carboxylic acid and quinizarin were isolated from endophytic fungus Epicoccum nigrum and their cytotoxicity, antibacterial and antioxidant activity were evaluated. Beauvericin had remarkable activity against two Gram-negative strains (Bacillus cereus and Salmonella typhimurium)

4. Finite element modeling for buckling analysis of hybrid piezoelectric beam under electromechanical loads
A one-dimensional finite element model for buckling analysis of hybrid piezoelectric beams under electromechanical load is presented in this work. The coupled zigzag theory is used for making the model. The inplane displacement is approximated as a combination of a global third order variation across the thickness with an additional layer wise linear variati

5. Weak solutions for the electrophoretic motion of charged particles
We introduce a weak formulation for a system of electrostatic and hydrodynamic equations modelling the electrophoretic motion of charged particles in ionized fluids. We obtain a local in time existence theorem, using the results established in [11] and properties of the solutions of the Poisson-Boltzmann equation. These properties follows from singular integ

6. Topological sensitivity analysis for a two-parameter Mooney-Rivlin hyperelastic constitutive model
The Topological Sensitivity Analysis (TSA) is represented by a scalar function, called Topological Derivative (TD), that gives for each point of the domain the sensitivity of a given cost function when an infinitesimal hole is created. Applications to the Laplace, Poisson, Helmoltz, Navier, Stokes and Navier-Stokes equations can be found in the literature. I

7. Capital social em uma comunidade do meio oeste catarinense
The relationship between social capital and development, puts the concept in the academic calendar, in the formulation of public policies and development projects of international organizations. However, this growing debate is still modest when seen in the scientific literature on the subject, especially in terms of examining the dimensions of social capital

8. EQUAÇÕES DE NAVIER-STOKES: ASPECTOS FÍSICOS E SOLUÇÃO FRACA EM ESPAÇOS DE SOBOLEV
In this work, based on the Law of conservation of mass and the Newtons second Law, we deducted the equations of Navier-Stokes for the uncompressing fluids. Then we have developed in a detailed way the varying form of these equations. For this formulation, through the Galerkin method, we have proved the existence of weak solutions in Sobolev spaces in a bound

9. Princípios básicos e aplicação da iontoforese na penetração cutânea de fármacos
Physicochemical constraints severely limit the number of molecules that can be considered as candidates for transdermal delivery. Iontophoresis is a non-invasive technique in which a weak electric current is used to enhance the penetration of molecules into or through the skin. In this review the underlying mechanisms that drive iontophoresis and the impact

10. Um modelo geometricamente exato de barras com grandes deformações, que considera a distorção e o empenamento geral da seção transversal, e sua discretização pelo método dos elementos finitos. / A fully nonlinear geometrically exact multi-parameter rod model that incorporates general in-plane and out-of-plane cross-sectional changes, and its discretization by Finite Element Method.
The main purpose of this work is to present a fully nonlinear geometrically-exact multi-parameter rod model that incorporates general in-plane cross-sectional changes as well as general out-of-plane cross-sectional warping. The formulation constitutes an extension of the earlier works presented in [1] to [6], [8] and [9], in the sense that the restrictions t

11. A biologia moral: a constituição do sujeito (des)atento / The moral biology of attention: the constitution of the (in)attentive individual
The objective of this work is to analyze the constitution of the attentive and inattentive individual within the historical process of the moral biologisation of attention. This thesis divides the history of the moral biology of attention into three main phases: the second half of the eighteenth century; the second half of the nineteenth century; the last th

12. Electrostatic waves in a Maxwellian dusty plasma with variable charge on dust particles
A kinetic formulation developed to analyze wave propagation in dusty plasmas, which takes into account the variation of the charge of the dust particles due to inelastic collisions with electrons and ions, is utilized to study the propagation and damping of electrostatic waves with wave number exactly parallel to the external magnetic field and Maxwellian di
