This work addresses the erosion caused by rain, describing their steps and factors that most influence the intensity and volume of transported material. The work presents the Universal Soil Loss Equation that quantifies the erosion, with the influence of different factors that affect it. The following notes the occurrence of this process in cutting slopes. They suffer with removal of the vegetation and surface soil layer, making them even more susceptible to this process. In this way it's necessary a protection model for the slopes. Some protection methods are presents with their main features, advantages and disadvantages, implementation process, especially to survey the approximate cost of each method and their application restrictions

This essay aims to contribute to discuss public policies of social protection and practice guidelines for psychosocial care. Targeting children and underage adolescents whose documents, even though permeated with egalitarian discourses and promoted actions aimed at the construction of autonomy, continue endorsing welfare guardianship and addressed to the people classified as at-risk through biopolitical, disciplinary and security technologies based on a minority logic. The essay problematizes the ways in which psychology has found legitimacy in practices that eventually looms confinement practices which aspire to move away from, as was evidenced by documents and practices.

Using the sol-gel process, organic-inorganic hybrid coatings were synthesized by incorporation of different concentrations of functionalized carbon nanotubes, to improve their mechanical strength and thermal resistance without changing its passivation character. The siloxane-PMMA hybrids were prepared by radical polymerization of methyl methacrylate (MMA) with 3-methacryloxipropiltrimethoxisilane (MPTS) using the thermal initiator benzoyl peroxide (BPO), followed by acid catalyzed hydrolysis and condensation of tetraethoxysilane (TEOS). The analysis of pristine and functionalized carbon nanotubes was carried out using Scanning Electron Microscopy, X-ray Photoelectron Spectroscopy and Raman Spectroscopy. Structural analysis of hybrids was performed by Nuclear Magnetic Resonance, Atomic Force Microscopy and Raman Spectroscopy. For analysis of mechanical strength and thermal stability were performed mechanical compression tests and thermogravimetric analysis, respectively. Electrochemical Impedance Spectroscopy was used to evaluate the corrosion resistance in saline environment. The results showed an effective functionalization of carbon nanotubes with carboxyl groups and conservation of its structure. The hybrids showed high siloxane network connectivity and roughness of approximately 0.3 nm. The incorporation of carbon nanotubes in the hybrid matrix did not change significantly their thermal stability. Samples containing carbon nanotubes exhibit good corrosion resistance (on the order of MΩ in saline environment), but the lack of complete dispersion of carbon nanotubes in the hybrid, resulted in a loss of mechanical and corrosion resistance compared to hybrid matrix.

Since the beginning of time man has used body ornaments, often-simple element of decoration, passing by the object ritualistic and religious icon, also as a symbol to the demonstration of status and power. Many of these objects have survived to today, but the vast majority is lost in time or was dismantled to reuse the material in new jewelry. The history of jewelry uses the pieces that have survived intact, documents and images of those jewels. This work uses of Visual Arts, more specifically the portrait art of, to analyze the mystical amulets of child`s protection jewel in works of painters Juan Pantoja dela Cruz and Diego Velásquez.

My purpose is to reflect critically on how Benjamin Libet interprets his experiments, which are focused primarily on the question of free will. These experiments have often been considered as scientific evidence against free will, to the extent that they would have shown that the intention and will result from conscious brain processes, which are unconscious and precedents. But that is not the position of Libet, which distinguishes intention and conscious will, arguing that only the first results from previous and unconscious brain processes, while the second is autonomous and able to act causally on brain. Thus, Libet choose to ignore the suggestion of its initial experiments, that is, that all mental events result of specific brain processes. I argue that Libet ignores it because he is not able to understand how mental events, being essentially separated and at the same time the result of brain activity, could act causally on the brain.

This work presents the results of the efficiency of three protection methods of roads slopes, against the development of erosion processes.The methods anlyzed were: (1) grass planting "San Carlos" (Axonopus compressus), (2) litter, composed of remains of branches and leaves of eucalyptus E. Grandis, and (3) Compacted soil cover with a local soil with properties more resistant to erosion processes.The experiment consisted of assembly of four rectangular cells with 6 meters, three for protection systems in study and one was kept unprotected to evaluate the efficiency of the methods in study.The determination of the amount of eroded sediment was based on the sum of the solids in suspension and stored sediments in the geotextile bags.The results showed that, compared to the unprotected cell, the litter obtained a reduction of soil loss of 90%, while the grass enveloped and reduced 80% and 65% respectively.

The constant misuse of land in Permanent Preservation Areas (APPs) have been recurrent, especially in urban areas, where the dynamics of change is constant. The protection of these areas to maintain a balance in the ecosystem and the population's quality of life is fundamentally important. So it is of utmost important to draw up a mechanism that can help in decision-making in relation to measures for the protection, mitigation of damages that are being caused and revitalization of these areas. Thus, a managing these areas based on the PMBOK (Project Management Body of Knowledge) in order to create mechanisms to facilitate the protection and revitalization of APPs, could be of great help for making public decision-making bodies that are entrusted to protect such areas. Based on this, we elaborated a project management in order to revitalize and protect the APPs in urban area of Rio Claro, SP and could become a model for future use by public bodies
