Agricultural production and sustainable development in a Brazilian region (Southwest, Sao Paulo State): motivations and barriers to adopting sustainable and ecologically friendly practices

The objective of this study is to identify the adoption level of practices associated with more sustainable agriculture and environmentally friendly practices. Additionally, the motivations for and barriers to the adoption of these practices by farmers are investigated. Data were collected through closed questionnaires taken by a random sample of farmers in the Southwest, Sao Paulo, Brazil, during the second half of 2013. Overall, sustainable agricultural practices recommended in the literature and analysed in this study are being not fully adopted by farmers of the studied area. The results showed that financial motivation is associated with farmers adopting new, more sustainable technology, whereas the lack of information on and lack of technical support for these technologies are significant barriers. Other results, research implications, limitations and suggestions for future research are presented.

Nonlinear state estimation and control applied to a manipulator robotic including drive motor

A robotic control design considering all the inherent nonlinearities of the robot engine configuration is developed. The interactions between the robot and joint motor drive mechanism are considered. The proposed control combines two strategies, one feedforward control in order to maintain the system in the desired coordinate, and feedback control system to take the system into a desired coordinate. The feedback control is obtained using State Dependent Riccati Equation (SDRE). For link positioning two cases are considered. Case 1: For control positioning, it is only used motor voltage; Case 2: For control positioning, it is used both motor voltage and torque between the links. Simulation results, including parametric uncertainties in control shows the feasibility of the proposed control for the considered system.

A influência das universidades públicas de São Carlos-SP na dinâmica do espaço geográfico: a importância da população estudantil para o setor imobiliário

The city of San Carlos is known to have important centers of research aimed at developing high technologies, which are: Federal University of São Carlos (UFSCar), the University of São Paulo (USP). Thus, the portion of the population of students who are not from the city of San Carlos, but it has to be present daily to provide their respective courses in San Carlos, has the need to rent property. The housing market, in turn, uses the application of capital to meet the demands of students and business is taking steps that make the production of space and provide new scope of the place, giving new meaning to the settings and new residents. This work goes towards understanding the students, social workers, boosting growth in this market and the influences of space and real estate agents and their actions materialized in space to meet this demand
