13. A convergência estratégica em Arranjos Produtivos Locais: uma análise sobre a cooperação entre atores em rede em duas regiões cafeeiras
Resumo: O desenvolvimento de novos Arranjos Produtivos Locais (APLs) no Brasil é um tema de extrema importância no atual contexto econômico e social brasileiro. As Indicações Geográficas (IG) surgem com o objetivo de proteger e valorizar produtos e serviços típicos de uma região. O resultado é que estes APLs que buscam reconhecimento de origem nece

14. Digital Approach for Measuring Tree Diameters in the Amazon Forest
ABSTRACT Buttresses and other natural structures modify the shape of stems in Amazonia and change the diameter at breast height (DBH) measured at 1.3 m at ground level. The lack of adequate measurement techniques affects negatively forest dynamics analyses and biomass estimating. The study evaluated an indirect method of measuring diameters in trees with DB

15. Research on the Folding Patterns and Deployment Dynamics of Inflatable Capsule Structures
ABSTRACT: The folding patterns and deployment dynamic characteristics of conical inflatable capsule structures were investigated. A six-fold-line method of packing a conical shell surface was designed. The fold-line layouts and relation formulas of the fold angles were determined. The folded state of the inflatable capsule structure was parametrically modele

16. GFEM STABILIZATION TECHNIQUES APPLIED TO DYNAMIC ANALYSIS OF NON-UNIFORM SECTION BARS
Abstract The Finite Element Method (FEM), although widely used as an approximate solution method, has some limitations when applied in dynamic analysis. As the loads excite the high frequency and modes, the method may lose precision and accuracy. To improve the representation of these high-frequency modes, we can use the Generalized Finite Element Method (GF

17. The Dusseldorf Illustrated Schema Questionnaire for Children (DISC)
Abstract Childhood experiences are considered to be of crucial importance in the formation of maladaptive schemas, according to Young's concept. Although some schema questionnaires already exist for children, these instruments differ in their schema structures with between 8 and 12 identified factors. To obtain a deeper understanding of early maladaptive sch

18. Molecular Dynamics Simulations of Cetyltrimethylammonium Bromide (CTAB) Micelles and their Interactions with a Gold Surface in Aqueous Solution
Surfactants are molecular structures with remarkable physicochemical properties and applications. Most of their characteristics are due to their ability to promote aggregation and interactions with different interfaces. The scarcity of theoretical studies dedicated to evaluating the forces involved in these interactions prompted us to propose other models ca

19. Organic Matter Stocks and the Interactions of Humic Substances with Metals in Araucaria Moist Forest Soil with Humic and Histic Horizons
ABSTRACT Soils with humic and histic horizons in tropical and subtropical ecosystems play an important role in determining the atmospheric C stock and its stabilization, climate regulation, water holding capacity, and environmental filtering, due to the different functions of soil organic matter (SOM). However, the processes and mechanisms that regulate SOM

20. Population dynamics of the mud crab Panopeus austrobesus Williams, 1983 (Brachyura: Panopeidae) associated with a mussel farm at the southeastern Brazilian coast
Abstract Mussel farms are one of the most important modalities of aquaculture and constitute almost 80% of the total bivalve production in Brazil, representing about 5% of the national production. Brachyuran crabs are common inhabitants of these environments and represent an important link in coastal marine food chains. The aim of this investigation is to de

21. Stretching the Limits? Strengths and Pitfalls of South Atlantic Security Regionalism
Abstract In the broader context of regional studies, the South Atlantic comes across as a singular, yet still understudied case study for the formation, evolution, and regression of security regionalism dynamics. More so when South Atlantic countries have come to engage in increased regionally focused interactions through wider defence co-operation ties. How

22. Impactos de la dinámica urbana en los mercados laborales en las principales ciudades chilenas
Abstract Economic and financial liberalization reforms, in most Latin American countries, have led to a radical change in the structure of material production in the region. In this context, this paper aims to identify and characterize the link between the growth trends of the main Chilean cities and the evolution of their urban labor markets, seeking to cla

23. Outer cell wall structure and the secretion mechanism of colleters of Bathysa nicholsonii K. Schum. (Rubiaceae)
ABSTRACT Secretory structures are formed by many types of plants and are present on numerous different organs. Among the many types of known secretory structures, colleters are predominant on plants of the Rubiaceae. One remarkable characteristic of secretory tissues is the export of exudates; however, the precise mechanism involved in this process is still

24. Nonlinear Dynamics Analysis of FGM Shell Structures with a Higher Order Shear Strain Enhanced Solid-Shell Element
Abstract In this paper, non-linear dynamics analysis of functionally graded material (FGM) shell structures is investigated using the higher order solid-shell element based on the Enhanced Assumed Strain (EAS). With this element, a quadratic distribution of the shear stress through the thickness is considered in an enhancing part. Material properties of the
