1. Foreign direct investment in developing economies A study on the productivity spillover effects in Latin America
Abstract Purpose The aim of this study was to investigate how the productivity spillover effects of foreign direct investment (FDI) in the Latin American economies are manifested. Specifically, the paper sought to identify the role of foreign presence and government intervention through an industrial policy on total factor productivity in Latin American cou

3. Non-Durable Consumption and Real-Estate Prices in Brazil: Panel-Data Analysis at the State Level
Resumo Este artigo investiga o efeito da variação dos preços dos imóveis sobre o consumo de bens não duráveis no Brasil. Para isso, construímos um painel estadual com informações sobre o consumo de bens não duráveis para o período 2008-2017, período que abrange o “boom” dos preços de imóveis e do consumo (2008-2014) e a queda dos mesmos (2

4. ARTIFICIAL NEURAL NETWORKS APPLIED IN FOREST BIOMETRICS AND MODELING: STATE OF THE ART (JANUARY/2007 TO JULY/2018)
ABSTRACT Artificial Intelligence has been an important support tool in different spheres of activity, enabling knowledge aggregation, process optimization and the application of methodologies capable of solving complex real problems. Despite focusing on a wide range of successful metrics, the Artificial Neural Network (ANN) approach, a technique similar to t

7. Multivariate Analysis and Machine Learning in Properties of Ultisols (Argissolos) of Brazilian Amazon
ABSTRACT: Ultisols are the most common soil order in the Brazilian Amazon. The Legal Amazon (LA) has an area of 5 × 106 km2, with few accessible areas, which restricts studies of soils at a detailed level. The pedological properties can be estimated more efficiently using statistical procedures and machine learning techniques, tools which are capable of rec

8. 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

9. Método para el estudio de la producción informativa: medios digitales de Portugal
Abstract The present investigation proposes a method of analysis of information production of digital media. The method employed consists of the analysis of information production, which can be collected from syndication channels in the press media, radio and digital television. The syndication channels of digital media in Portugal has been taken as an examp

10. Volatile Compounds from the Bark Bugs Phloea subquadrata and Phloeophana longirostris (Heteroptera: Phloeidae)
Phloea subquadrata and Phloeophana longirostris are subsocial species that differ from each other in their host plants and degrees of aggregation. Until recently, only ten low-molecular weight compounds, a sesquiterpene, and dimers of (E)-4-oxo-2-hexenal had been reported from the contents of P. subquadrata glands. Here, the main goal was to distinguish the

11. SÍNTESE E CARACTERIZAÇÃO DE SURFACTANTES ALQUILFENIL POLIGLICOSÍDICOS A PARTIR DA AMILOSE E ALQUIL FENÓIS EXTRAÍDOS DO LCC NATURAL
The surfactants were synthesized by condensing the obtained oligosaccharides of amylose and alkyl phenols extracted from the natural cashew nut shell liquid (nCNSL). The Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared Spectroscopy (FTIR) data showed aromatic ring bands, glycosidic rings, olefins and paraffins. The Nuclear Overhauser Effect Sp

12. Colloidal Dispersion Stability: Kinetic Modeling of Agglomeration and Aggregation
In this work we present a simple model for the kinetics of agglomeration and aggregation of colloidal particles. We consider that particles agglomerate rapidly and endothermically forming oligomers. These oligomers can, in turn, aggregate irreversibly, in a process that leads to the destabilization of the colloidal system. As these two processes have very di
