1. Questões de cronologia rousseauísta: o caso do Ensaio sobre a origem das línguas
Resumo: O século XX viu ganhar forma um efervescente debate travado em torno do Ensaio sobre a origem das línguas de Rousseau, sobretudo quanto à sua gênese, ao período em que foi escrito e às suas possíveis relações com o Discurso sobre a origem da desigualdade. O presente artigo, ao repassar a literatura crítica sobre o tema, propõe uma cronolog

2. The Research on Porphyrins and Analogues in Brazil: A Small Review Covering Catalytic and other Applications since the Beginning at Universidade de São Paulo in Ribeirão Preto until the Joint Venture between Brazilian Researchers and Colleagues from Universidade de Aveiro, Portugal
The synthetic versatility and the potential applications of porphyrins and analogues in different fields have aroused special interest in their study, especially to mimic biological systems, such as cytochrome P-450. The ability of the porphyrin tetrapyrrolic core to accommodate metal ions of varying charges can modulate the type of application of these comp

3. Temporal stability of soil moisture in banana cropping area in the Brazilian semiarid region
RESUMO A umidade do solo é essencial para a produção agrícola. O conhecimento de sua variabilidade espaço-temporal é indispensável para suporte à agricultura, sendo fortemente influenciada pelas práticas culturais, condições de cobertura do solo e métodos de irrigação. Assim, este estudo teve como objetivo avaliar a estabilidade temporal e a di

4. Microalgae: Cultivation Aspects and Bioactive Compounds
Abstract Microalgae are aquatic unicellular microorganisms that can be found both in freshwater and marine systems; are capable of photosynthesis; and can grow as individual cells or associated in chains or small colonies. Microalgae cultivation has gained large momentum among researchers in the past decades due to their ability to produce value metabolites,

5. TRACTIVE DEMAND, SOIL MOBILIZATION PARAMETERS, AND CORN YIELD IN COMPACTED OXISOL
ABSTRACT Direct seeding systems are characterized by soil disturbance only occurring in the sowing line and the maintenance of the remaining area is achieved by covering with crop residues. Without total area soil mobilization as recommended by the no-tillage system, associated with the increase in the degree of soil compaction caused by the traffic of agric

6. The Mato Perso Conduit System: evidence of silicic magma transport in the southern portion of the Paraná-Etendeka LIP, Brazil
ABSTRACT: The Mato Perso Conduit System is described from a ~ 120 km2 area in south Brazil exposing silicic volcanics of the Paraná-Etendeka LIP. A volcanic succession is defined by basaltic flows covered by flat-lying oxidized vitrophyres, banded vitrophyres cutting the lower lavas and grey flat-lying vitrophyres covering all the units. Flow morphologies d

7. ECOLOGICAL-ECONOMIC ZONING OF THE CITY OF ALTINÓPOLIS – SP, BRAZIL
ABSTRACT: Since colonial times, Brazilian land use has been made under an extractivist model at the expense of deforestation, increasing soil and vegetation depletion, stream siltation, as well as loss of biodiversity. An ecological-economic zoning (EEZ) has been taken as feasible alternative to guide public policies aimed at city land-use planning. This stu

8. BASIC UNIT COST SIMULATION FROM FREE-STALL DESIGN TO DAIRY CATTLE CONFINEMENT USING DIFFERENT CONSTRUCTION TECHNIQUES
ABSTRACT The ascendancy of milk production in Brazil is due to mainly to the adoption of confinement systems, however, construction quality of these systems impact on milk production. This study aimed to simulate the Basic Unit Cost (BUC m-2), referring to a free-stall design with capacity for 80 animals and different construction techniques, with a database

9. LOCATING PUBLIC SCHOOLS IN FAST EXPANDING AREAS: APPLICATION OF THE CAPACITATED p-MEDIAN AND MAXIMAL COVERING LOCATION MODELS
The area of Guaratiba, in Rio de Janeiro, presents extraordinary population growth rates that exceed all other districts of the city. Moreover, the public investments underway, in view of the 2106 Olympic Games, are making the region even more attractive. Therefore, it is appropriate to suggest proactive measures to avoid the predicted collapse of several pu

10. Avalanches e redes complexas no modelo Kinouchi-Copelli / Avalanches and complex networks in Kinouchi-Copelli model
The capacity of a sensory system in efficiently detecting stimuli is usually given by the dynamic range, a simple measure of the range of stimulus intensity over which the network is sensible enough. Many times biological systems exhibit large dynamic ranges, covering many orders of magnitude. There is no easy explanation for that, since individual neurons p

The main objective of this study is quantify the impact caused by changes in federal tax on the tax policy of the states, considering the presence of horizontal tax competition between states. In federal systems, where various levels of government operate simultaneously in the same tax regime, setting tax rates on the same basis of taxation, there may be the
