The research shows that increasing the consumption of energy by households is growing rapidly and without adequate planning, due to population growth and therefore an increase in energy consumption. With the current concerns of sustainability and energy efficiency by industry, there is the need to prove to population that there are many ways to incorporate sustainable practices to their daily lives, starting from by their own residence. The quality certification of the energy efficiency level in residential buildings, shows how one can influence and improve housing issues on sustainable actions as rooted in our country

Mobility and accessibility are terms that are related to each other. Large urban centers now face problems arising from rapid population growth and among them are problems inherent to mobility and accessibility. The aim of this paper was to conduct a literature review, from a review in journals and books on the issue of mobility in urban centers, showing how mobility is associated with accessibility. A key finding was that the new social reality is the challenge for the future planning of cities and in these cases should be used the knowledge of design, architecture, urbanism and urban planning to address these problems.

The rising in greenhouse gases emission as consequence of industrial expansion especially in developing countries is appointed as one of those reasons responsible for global warming. High-level temperatures are set as responsible for low productivity and high levels of discomfort. With the increase of worldwide energy demand, due to the population growth, this work aims to be an introductory text revising the current ventilation (mechanical and natural) and refrigeration technologies as well as low energy cooling techniques and architectural alternatives that seeks offering good ventilation and ideal buildings temperatures, making them sustainable. In addition, the text deals with the measurement instruments used to evaluate the parameters defined by international and national standards. At last, a case of study applies few concepts and technologies described in the text, introducing the results achieved, the limitations and suggestions to future works

The main purpose of this study is to perform a nitrogen budget survey for the entire Brazilian Amazon region. The main inputs of nitrogen to the region are biological nitrogen fixation occurring in tropical forests (7.7 Tg. yr(-1)), and biological nitrogen fixation in agricultural lands mainly due to the cultivation of a large area with soybean, which is an important nitrogen-fixing crop (1.68 Tg. yr(-1)). The input due to the use of N fertilizers (0.48 Tg. yr(-1)) is still incipient compared to the other two inputs mentioned above. The major output flux is the riverine flux, equal to 2.80 Tg. yr(-1) and export related to foodstuff, mainly the transport of soybean and beef to other parts of the country. The continuous population growth and high rate of urbanization may pose new threats to the nitrogen cycle of the region through the burning of fossil fuel and dumping of raw domestic sewage in rivers and streams of the region.

This article focuses on some aspects of the agrarian history of Soledade, a town in the north of the state of Rio Grande do Sul, southern Brazil. Our aim is to understand how this area was in many ways affected by the Land Law of 1850, particularly in economic and social terms. Population growth, arrival of European immigrants and increasing privatization of the commons contributed for the increasing of land prices in the region during the second half of the 19 th century. Understanding this situation as a great opportunity to make money, some landowners, directly or through a colonization company, allotted and sold the land they had previously acquired through the Land Law of 1850
