3. Energy embodiment in Brazilian agriculture: an overview of 23 crops
The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a v

4. Controle da velocidade e da direção entre dois veículos agrícolas / Speed and steering control between two agricultural vehicles
One problems of the mechanical harvest of sugar cane is the lack of synchronization between the harvester and field wagon. This problem can causes crop losses as well as reducing operational capacity. The first occurs when the machines are misaligned and part of the sugar cane is thrown out of the wagon. The operational capacity reduce occurring when the mac

5. Dinâmica folicular de vacas de corte tratadas com três protocolos de sincronização da ovulação =Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation / Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation
Background: Artificial insemination is an established and viable technique to accelerate the genetic advancement and economic return of the cattle. However, compromises the efficiency of detection of estrus results in low insemination rates. To avoid these problems in beef herd, synchronization protocols have been developed that allow inseminate large number

6. Regionalização de vazões de referência Q7,10 e Q90
The main objective of the research was the study and application of different methods for estimating ten years return period minimum annual seven consecutive days low flows (Q7,10) and minimum flows associated with remaining 90% in time (Q90), for the region between Doce and Itabapoana basins, through the hydrological regionalization. The three compared meth

9. Testing the Optimality of Aggregate Consumption Decisions: Is there Rule-of-Thumb Behavior?
Consumption is an important macroeconomic aggregate, being about 70% of GNP. Finding sub-optimal behavior in consumption decisions casts a serious doubt on whether optimizing behavior is applicable on an economy-wide scale, which, in turn, challenge whether it is applicable at all. This paper has several contributions to the literature on consumption optimal
