Financial system, innovation and regional development: a study on the relationship between liquidity preference and innovation in Brazil

This paper discusses and assesses the features of the Brazilian Financial System, as well as the impacts of Liquidity Preference on Credit and Regional Development in Brazil. Precisely, we test the relationship between credit and development, and the role of banks in regional development. We estimate a panel across states in Brazil in order to test the impact of liquidity preference and other financial variables on Brazilian states credit level. We have also tested the relationship between liquidity preference and other financial variables across states and the number of patents, aiming at testing the importance of technology and innovation on regional development by means of bank system. Conclusions confirm both hypotheses.Monetary System, National Innovation System, Credit

Self-adjusting orthoses design

This paper proposes an approach to the development of a customized 3D printed multi-material cervical orthosis that combines new production techniques with smart materials and biomimetic structures. It suggests a lightweight, waterproof, ventilated, hygienic and comfortable orthoses designed specifically for each patient in collaboration with doctors, additive manufacturing specialists and designers. The combination of innovative production techniques with smart materials can generate an enhanced product, whose added value can be perceived by differentiated attributes and applications

Financial system, innovation and regional development: a study on the relationship between liquidity preference and innovation in Brazil

This paper discusses and assesses the features of the Brazilian Financial System, as well as the impacts of Liquidity Preference on Regional Development in Brazil. In the post-Keynesian literature, money is considered endogenous to the economic system, introduced in the economic activity through the credit provided by banks. Taken as non-neutral, banks are economic agents which can present lower or higher liquidity preference. Because of that, banks are also particularly important to the development process. Precisely, we tested the influence of credit and the role of banks in regional development. We estimate a panel across states in Brazil in order to test the impact of liquidity preference and other financial variables on Brazilian states’ number of patents, aiming at testing the importance of the bank system to technological progress and regional development. Conclusions confirm both hypotheses.Monetary System, National Innovation System, Credit, Brazil

Adsorption of two pesticides on a clay surface: a theoretical study

The contamination of water resources with many organic xenobiotic compounds poses a challenge to environmental sciences and technologies [1]. Although in many cases these contaminants are present only in small concentrations, the large variety of such compounds (some of which are classified as priority pollutants) is a matter of concern. Adsorption, alone or as part of a more complex water or wastewater treatment process, has been seen as playing a very important role in the removal of many of these pollutants [2]. In this regard, the choice of adsorbent materials is crucial, which requires an understanding of the details involved in the adsorption of more or less complex organic molecules by a variety of surfaces of different types. In addition to laboratory studies, computational studies may be valuable in this study [3]. MCPA (2-methyl-4-chlorophenoxyacetic acid, a herbicide) and Clofibric acid (2-(4-chlorophenoxy)-2-methylpropanoic, the metabolite of a pharmaceutical, clofibrate, and also a herbicide) are two phenoxy acids that differ only slightly in their structures. However, a quite distinct behavior in adsorption phenomena on clay materials has been observed in past studies [4]. By relating those differences with the molecules' structural features through atomistic computational studies, some insight may be gained into the respective adsorption processes of this type of compounds. In the present work quantum chemical calculations at density functional theory level have been performed to study the adsorption of MCPA and Clofibric acid by a clay surface model. Since hydration plays an important role for the adsorption process of these species, solvent effects were considered by inclusion of water molecules explicitly into the quantum chemical calculations. The deprotonated negatively charged species were found to strongly interact with the surface and the distinct behavior of both species upon adsorption was compared with experimental evidences
