This paper aims to investigate the use of m-government applications for public services providing in Brazil. As a secondary objective, the paper aims to analyze the relationship between the use of m-government applications and development.

To achieve the objective of this research, the 100 smartest cities of Brazil were selected and the mobile apps provided by their local governments were identified. Both qualitative and quantitative methods were adopted, including content analysis technique, chi-square test and regression analysis.

The results show that mobile apps developed by local governments of Brazilian smart cities include information and public services access, health, education, security, tourism, water supply system, environment, among others. The results also show a positive relationship between apps downloads and development indexes.

This paper emphasizes the social side of information technology, showing that it can contribute to the implementation of more inclusive cities that respond to the needs and interests of their citizens.

This paper presents empirical evidences of the potential benefits of m-government technologies for development in an emerging country. Moreover, it highlights how mobile applications developed by local governments may lead to a better quality of life of the population, considering a comprehensive approach of development that involves its economic, social and human dimensions.

The purpose of this paper is to characterize oils extracted from Bertholletia excelsa, Lecythis pisonis, Dipteryx lacunifera, Carya illinoensis and Juglans regia, regarding their characterization and fatty acid profile.

The oils were extracted from oilseeds by cold pressing and physico‐chemical characterization was performed by using standard methods for oils and fats. The oxidative stability and fatty acid profile also were determined.

According to the results, the physico‐chemical properties of oils from nuts and walnuts were comparable to those of good quality conventional oils. The oil seeds are a good source of unsaturated fatty acids, especially oleic and linoleic acids.

Implies the identification of fatty acid profile and physico‐chemical properties of oils extracted from nuts and walnuts, and to prevent certain types of diseases.

The paper identifies a new source of essential fatty acids extracted from oilseeds.
