Investigation of the Nature and Number of Surface Active Sites of Supported and Bulk Metal Oxide Catalysts Through Methanol Chemisorption
(CRC Press - Taylor & Francis Group, 2005)
The present Chapter presents a chronological summary of the application (advantages and disadvantages) of probe molecules both in the liquid and gas media to investigate the surface of oxide based materials and heteropoly ...
Convecção natural e radiação em cavidade aberta preenchida com meio poroso heterogêneo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2014-05-08)
Although of relevance to a variety of engineering applications, the study of natural convection within an open cavity containing a conducting solid body is rarely found in the literature. Moreover, previous studies have ...
Searching new antifungals: The use of in vitro and in vivo methods for evaluation of natural compounds
(2016-04-01)
In the last decades, the increased number of immunocompromised patients has led to the emergence of many forms of fungal infections. Furthermore, there are a restricted arsenal of antifungals available and an increase in ...
Investigação numérica da convecção natural de fluido de Bingham em cavidade fechada preenchida com meio poroso

Power-law distribution in a learning process: competition, learning and natural selection
(Elsevier B.V., 2005-01-01)
In the present work, we propose a model for the statistical distribution of people versus number of steps acquired by them in a learning process, based on competition, learning and natural selection. We consider that ...

Development of a competitive natural gas market
(FGV CERI, 2017)
Since 1997, Brazil has been flirting with the idea of creating a market for natural gas. However, the industry requires a vision and solutions beyond engineering challenges: it requires a market design underpinned by a ...
Simulación del proceso de endulzamiento de gas natural usando solución acuosa de monoetanolamina.
(Escuela Superior Politécnica de Chimborazo, 2019-06-17)
The riddance of the acid components of natural gas is known as sweetening, this is achieved through its absorption with basic solutions such as alkanolamines, throughout a reversible exothermic reaction, which subsequently ...
