1. Rethinking abusive supervision: antecedents and reparative mechanisms of abusive supervision, including supervisor frustration, coworker support, guilt, and supervisor OCB in a mediated-moderation model
Abstract Purpose Drawing on affective events theory, this study positions role overload and supervisor frustration as antecedents of abusive supervision, leading to supervisor-led organizational citizenship behavior. In a mediated-moderation-sed analysis, we question whether coworker support moderates the relationship between supervisor frustration and abus

2. Chemometric Evaluation of Poly(3-hexylthiophene) Electrochemical Aging Path as a Function of Electrochemical Synthesis Variables
Conductive polymers are versatile materials that can be applied in many different technology fields, especially green energy. They have several advantages, such as easy synthesis, low density, and cost. However, its electric conduction property is also related to material aging with great loss of their characteristics, limiting their applicability. The in-de

3. Impact of Sexual Orientation, Social Support and Family Support on Minority Stress in LGB People
Resumo Lésbicas, gays e bissexuais (LGB) podem apresentar menores níveis de saúde mental quando comparados a pessoas heterossexuais. Este estudo verificou o impacto da orientação sexual nos componentes do estresse de minorias (vitimização, homofobia internalizada e ocultação da orientação sexual), e o papel moderador dos suportes social e familiar

4. A Numerical Modelling of Mixed Mode Crack Initiation and Growth in Functionally Graded Materials
The main objective of this work is to present a numerical modeling of crack propagation path in isotropic functionally graded materials (FGMs) under mixed-mode loadings. The displacement extrapolation technique (DET) and the maximum circumferential stress (MCS) criterion are investigated in the context of crack growth in functionally graded beam subject to t

5. Numerical investigation of diffuse instability in sandy soil using discrete element method under proportional strain path loading
Abstract The Loose sandy soil can manifest static liquefaction phenomenon under undrained condition, in which the onset of instability is within the failure line, and there is no obvious shear band. This type of failure mode, very different from localized instability that occurs in dense sand, is called the diffuse instability. In this paper, a series of pro

6. Bone Anisotropy - Analytical and Finite Element Analysis
Abstract A human femur model, submitted to static loads, is analyzed through the utilization of three material constitutive relationships, namely: isotropic, transversally isotropic and orthotropic. The influence of bone anisotropy with respect to principal stress/strain distribution on human femur external surface was accessed through the use of analytical

7. Rayleigh waves in isotropic microstretch thermoelastic diffusion solid half space
This paper is devoted to the study of propagation of Rayleigh waves in a homogeneous isotropic microstretch generalized thermoelastic diffusion solid half-space. Secular equations in mathematical conditions for Rayleigh wave propagation are derived for stress free, insulated/impermeable and isothermal/isoconcentrated boundaries. The phase velocity, attenuati

8. Mechanical behavior of the shear-patch loading interaction on transversally stiffened steel plate girders
In this paper, the behavior of the intertwined shear and patch loading mechanisms in transversally stiffened steel plate girders is described. The phenomenological insight depicted in this paper shows the influence of the web thickness and the flange yield strength as well as the influence of the transverse stiffeners on the stress distribution, the critical

9. 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

10. Implementação de um algoritmo numérico para solução da equação de Christoffel generalizada em acustoelasticidade. / Implementation of a numerical algorithm for solution of the generalized Chistoffel equation in acoustoelasticity.
Extensive studies carried out in the last decades on the propagation of ultrasonic waves in solids led to the development of nondestructive techniques for the assessment of the safety and integrity of industrial structures and components. The interest in the application of ultrasound techniques for stress measurement for example comes from the measurable cha

11. Deficiência de tiamina e isolamento social afetam aspectos do comportamento motor e níveis centrais de GABA e glutamato
The main phenomenon approached in this study is the motor behavior, evaluated after two different types of environmental stimuli, the consumption of diet deficient in B1 vitamin and/or social isolation. The B1 vitamin, thiamine, is an essential nutrient for the nervous tissue. In previous studies, our research group has shown that the maternal thiamine defic

12. Simulações Monte Carlo de integrais de trajetória : propriedades elásticas do 4He sólido / Path integrals Monte Carlo simulations : elastic properties of 4He
The path-integral Monte Carlo (PIMC) method is a sophisticated approach for the simulation of many-body quantum systems. In particular, it has been extensively used for the study of manybody bosonic systems such as 4He. The main objective of the present dissertation is to apply the PIMC method to determine the elastic constants of solid 4He in its hcp phase.
