1. New Contours of the Native Vegetation Protection Law of 2012
ABSTRACT The conservation of natural resources within rural properties is a constitutional obligation. Among the social function criteria required for the exploitation of rural properties, besides the rational use and respect of working conditions, there is a need to ensure environmental protection. The current guidelines regarding the exploration and the en

2. TiO2 thin Films for Biofouling Applications
This work presents a study of TiO2 thin films prepared by sputtering, for using as protection for biofouling action on marine structures. Titanium oxide thin films were prepared with different amount of oxygen on the surface of regular 1020 steel, a structural material for marine technology. The cristalline structure analysis evidenced the formation of anata

3. Biological X-ray irradiator characterization for use with small animals and cells
This study presents the characterization of an X-ray irradiator through dosimetric tests, which confirms the actual dose rate that small animals and cells will be exposed to during radiobiological experiments. We evaluated the linearity, consistency, repeatability, and dose distribution in the positions in which the animals or cells are placed during irradia

5. Evaluation of the environmental sustainability of massive forestry fragments of the coastal plain and lower slopes of Bertioga (SP) / Avaliação da sustentabilidade ambiental dos fragmentos de maciços florestais da planície costeira e baixa encosta do município de Bertioga (SP)
The São Paulo coastal zone alternates extensive zones of great diversity of biotopes with others intensively degradated. These characteristics are observed in the municipality of Bertioga and its forest regions localized among Itaguaré and Guaratuba river basins. Due to their special characteristics these basins are denominated Bertioga System. The aim of

6. A regulação da proteção ambiental na Organização Mundial do Comércio-OMC
Esta dissertação, inserida nos parâmetros da revisão bibliográfica, buscou analisar as formas de regulação da proteção ambiental no âmbito da OMC. A OMC tem um escopo muito mais amplo que seu antecessor, GATT 1947, pois além de incorporar as diversas mudanças paulatinamente efetuadas no tratado que lhe precedeu, incluiu, ao longo da Rodada Urugua

7. Intraspecific variation in sensitivity to ambient ultraviolet-B radiation in growth and yield characteristics of eight soybean cultivars grown under field conditions
The present study was conducted with eight cultivars of soybean (Glycine max) to determine the effect of exclusion of solar UV-B on the vegetative growth (plant height, leaf area, no. of nodes), UV absorbing compounds (implicated in UV protection) and crop yield (No. of pods and seed weight) and to determine the cultivar difference in their sensitivity to am

8. Substituição da areia natural por areia de britagem de rochas basálticas para argamassas de revestimento
The present study has the purpose of evaluate the artificial sand, in substitution the extration sand, in mortars of covering. The substitution of percentage of the extration sand was also evaluated. The artificial sand is an alternative to the sand of extration in mortars, in view of the gradual exhaustion of the deposits of sand next to the great consumers

10. Participação do L-NAME, da L-arginina e da N-acetilcisteína no enfisema pulmonar induzido por fumaça de cigarro em camundongos / The lung remodeling in mouse emphysema is independent of nitric oxide modulation
Nitric oxide (NO) represents one of the most important intra and extracellular mediators/messengers. It takes part in both biologic and pathologic processes. This study aimed to verify NO role in pulmonary emphysema induced by cigarette smoke (CS) in mice. So L-NAME (LN) (a NOinhibitor) and L-arginine (LA) (a substract for NO formatio

11. Ablative and mechanical properties of quartz phenolic composites
Abstract. Quartz phenolic composites have been applied to thermal protection systems (TPSs) for reentry vehicles since the late fifties due to their excellent ablative resistance and mechanical performance. TPSs must withstand the aggressive reentry environment, such as atomic oxygen, when submitted to very high temperatures (> 1000° C) and heat flux. The a
