13. Análise do Impacto das Políticas de (Des)Oneração da Folha de Pagamento na Economia Brasileira
Resumo A política de desoneração da folha de pagamento foi implantada em 2012, mas em 2015 o Governo Federal estabeleceu mudanças que representaram uma reoneração da folha de pagamento. O objetivo é avaliar os impactos econômicos dessas políticas por meio de simulações com um modelo de equilíbrio geral computável dinâmico para a economia brasil

14. Heart disease and the stress hypothesis in the mid-twentieth century: a historical review
Abstract Background In the 1920s, heart disease (a noncommunicable disease), was the new leading cause of death in the USA. Simultaneously, experimental progress in the study of stress provided scientific justification for a new type of risk factor. The objective of the present work is to examine the history of heart disease as a public health problem and

15. A general method for designing non-symmetrical composite steel and concrete columns
Abstract The study of non-symmetrical composite columns is complex and European and North American standards only approach this issue superficially. In this text, a new proposal is presented for non-symmetrical composite column design subject to biaxial bending and axial compression, based on the compatibility of the deformation method, which considers the n

16. Agriculture and food security challenge of climate change: a dynamic analysis for policy selection
ABSTRACT This study presents an empirical examination of climate change related to vulnerability impacts on food security and remedial adaptation options as a suitable strategy by prioritizing needs over a 50-year period. An Empirical Dynamic Commutable General Equilibrium Model for Climate and the Economy (EDCGECE) is applied using future strategies for Mal

17. Equilibrium pricing and ordering policies in a two-echelon supply chain in the presence of strategic customers
ABSTRACT This paper studying the impact of strategic customer behavior on decentralized supply chain gains and decisions, which includes a supplier, and a monopoly firm as a retailer who sells a single product over a finite two periods of selling season. We consider three types of customers: myopic, strategic and low-value customers. The problem is formulate

18. SAIS DE TETRAFENILFOSFÔNIO E TRIS(1,10-FENANTROLINA)FERRO(II) DE COMPLEXOS ANIÔNICOS DE DIBUTILESTANHO(IV) COM DITIOCARBIMATOS: SÍNTESE, CARACTERIZAÇÃO E ATIVIDADE ANTIFÚNGICA
Six new salts of organometallic complexes of tin(IV) with the general formulae: (Ph4P)2[Sn(Bu)2(RSO2N=CS2)2] and [Fe(phen)3][Sn(Bu)2(RSO2N=CS2)2] [Ph4P = tetraphenylphosphonium, R = CH3 (1), C2H5 (2) and C4H9 (3); Fe(phen)3 = tris(1,10-phenanthroline)iron(II), R = CH3 (4), C2H5 (5) and C4H9 (6)] were synthetized from potassium dithiocarbimates (RSO2N=CS2K2.H

19. The general equilibrium theory as economic metatheory
Muitos economistas têm certo inconformismo em relação ao excesso de formalização matemática da economia. Isso emerge da insatisfação em relação a um debate antigo sobre a falta de correspondência com a realidade dos modelos teóricos de "mainstream". Embora não tenhamos a pretensão de resolver esse debate aqui, buscamos neste artigo associar a f

20. Nonlinear Equilibrium and Stability Analysis of Axially Loaded Piles Under Bilateral Contact Constraints
AbstractThis paper presents a nonlinear stability analysis of piles under bilateral contact constraints imposed by a geological medium (soil or rock). To solve this contact problem, the paper proposes a general numerical methodology, based on the finite element method (FEM). In this context, a geometrically nonlinear beam-column element is used to model the

21. State estimation of chemical engineering systems tending to multiple solutions
A well-evaluated state covariance matrix avoids error propagation due to divergence issues and, thereby, it is crucial for a successful state estimator design. In this paper we investigate the performance of the state covariance matrices used in three unconstrained Extended Kalman Filter (EKF) formulations and one constrained EKF formulation (CEKF). As bench

22. As primeiras impressões de Hicks sobre a Teoria Geral
In this article, we present an interpretation of the Hicks' first review of Keynes's General Theory. First we analyze the influence of Hayek's theory on the work of Hicks. We show how Hicks, reflecting on the Austrian theory of the business cycle, created the concepts of "week" and temporary equilibrium. Then we discuss how the author reformulated these conc

23. Tree community dynamics in a submontane forest in southeastern Brazil: growth, recruitment, mortality and changes in species composition over a seven-year period
In order to assess long-term community dynamics in tree populations, we investigated trees with a diameter at breast height (DBH) > 5 cm in an 11-ha fragment of submontane tropical forest in southeastern Brazil, at the beginning and end of a seven-year period. We observed a general tendency toward decreasing numbers of trees and toward stability in basal are

24. General exact harmonic analysis of in-plane timoshenko beam structures
The exact solution for the problem of damped, steady state response, of in-plane Timoshenko frames subjected to harmonically time varying external forces is here described. The solution is obtained by using the classical dynamic stiffness matrix (DSM), which is non-linear and transcendental in respect to the excitation frequency, and by performing the harmon
