Sustainable city is a city with characteristics that allow the improvement of population´s quality of life without destroying the natural resources available on it. Improve sustainability should be the goal of every government in charge of a city. The first step a public administrator should do is to define areas to focus on. Then, he should select indicators to measure the urban conditions and evaluate some aspects of the city.

Presently a-days from purchasing an item to watch to a film we are relying upon the audits. In times past we used to get some information about the item however now the situation totally changed. As of late, we have seen a twist of survey sites. It presents an extraordinary chance to share our perspectives for different items we buy. In any case, we face the data over-burdening issue. Instructions to mine significant data from surveys to comprehend a client’s inclinations and make an exact proposal are essential.

The commercial use of macauba oil feasible and make it a desirable species, where the hydrolysis process of trilglycerides is a promising alternative for obtaining fatty acids. After hydrolysis, glycerin is removed and the fatty acids generated later can be used for the production of biodiesel. This research also innovates due to the challenge of using heterogeneous catalysts based on niobium oxide impregnated with phosphoric acid, which presented superior results in the hydrolysis process when compared with H-USY zeolite.

This article aims to identify research strategies focused on methodological procedures and presentation of results in national and international quantitative studies, in the administration area, within a framework of critical-comparative analysis, in the period between 2015 and 2019. To develop this study, an exploratory-descriptive research was carried out, with a qualitative and bibliographic approach. For the treatment of the data it was used the content analysis technique, by means of Iramutec software, based on the phases described by Bardin (1977).

O hábito de fumar durante a gravidez continua sendo um grande problema de saúde pública. A fumaça do cigarro está intimamente relacionada à deficiência no desenvolvimento fetal, podendo acarretar déficits neurológicos, psicomotores, cognitivos e aumento de complicações comportamentais. O objetivo deste estudo foi descrever como o tabagismo pré-natal impacta no desenvolvimento neuropsicomotor infantil. Trata-se de uma revisão sistemática. As pesquisas foram feitas nas bases de dados: SciELO, PubMed, Bireme e Lilacs, no período de agosto a setembro de 2019.

Currently the use of smartphones is not only used as a means of exchanging information, but the sophistication of this mobile phone also offers many applications that can be used in daily activities. One of the applications available on a smartphone is a noise meter. The many types of noise measuring applications available on smartphones make it easier for users to select and use these applications. Therefore, it is necessary to know the accuracy of the noise meter application available on smartphones.

Looking at the processes of human history, it is known that in pre-agricultural communities, people started with hunting and gathering and adopted the nomadic life in order to continue their lives and meet their basic needs such as eating and drinking. One of the most important reasons for the prevalence of the nomadic life is that the climate and geographical conditions affect the meeting of basic needs such as food and shelter. Scientists divide human history into three parts as pre-agricultural, agricultural and industrial society.

The IDF equation is widely used in several engineering areas to estimate rainfall intensities with a specific duration and frequency. These equations can be adjusted based on the series of pluviographic records or by the disaggregation of daily rain in shorter duration rains. In the present study, a survey of the IDF equations published in Brazil was carried out in 118 different types of publications. Until 2010, 634 IDF equations were registered, predominantly (61%) generated by pluviographic data.

This study contributes theoretically, from empirical experiences, to the construction of correspondence practices between designers and artisans from a maroon community, Itamatatiua, in Alcântara, (Maranhão-Brazil). We propose the establishment of a ‘common plan’ to design by means of anthropology, thus we present parameters that help constitute this proposal.

This work is the result of a proposal for activities involving Unplugged Robotics, applied to the educational context, for a class of the 4th year of elementary school. The objective was to analyze how this resource can encourage and guide the stages of learning in an interdisciplinary perspective, reusing everyday materials, which would possibly be discarded. The practice developed was based on competencies and skills from the National Common Curricular Base, based on the theme of socio-environmental awareness, more specifically the environmental impacts caused by human action.
