Contaminação das águas subterrâneas por resíduos de postos de combustíveis: uma abordagem no município de Rio Claro

The contamination of underground waters is a subject of great importance, since a lot of people use this kind of source for public supply. This paperwork manages with how gas stations can contaminate these waters and what are some remediation techniques, used nowadays to solve this problem. The contamination caused by the gas stations can have its origin in the underground storage tanks when they suffer corrosion and show leaking problems. It’s a topic of great relevance, because the hydrocarbons derivated from petroleum present in the fuels can stay for a long time in the environment. Besides that, an analyses of the risk of contamination by gas stations in the city of Rio Claro was made based on three parameters: density of the gas stations, depth of the underground water and hydraulic conductivity. To achieve such goal, maps were elaborated considering those parameters individually and considering the three of them together. Analyzing those maps, it was concluded see that the spots that represent the biggest risks of contamination in Rio Claro are located southeast and center-west.

Radônio como indicador de contaminação de solos por hidrocarbonetos

Previous studies show that in areas contaminated by fuel spill (NAPL- non-aqueous phase liquids), from operational activities, transport and storage, it was possible to observe a significant decrease of ²²²Rn (radon) gas concentration in the soil, even a non-uniform distribution of this gas in top soil, even with a geological situation was practically homogeneous. These anomalies may be associated with the preference partitioning of radon in NAPLs. This work consists of applying ²²²Rn as an indicator for locating subsurface contamination by NAPLs in an area of the city of Rio Claro (SP) where, according to the “Survey of Contaminated and Rehabilitated Areas in the State of São Paulo (Environmental Sanitation and Technology Company - CETESB), there was, in the year 2007, groundwater contamination from leaks of liquid fuels. The challenges of this research are: Promulgate the use of a new tool with greater efficiency in obtaining results, in addition to generate less impact in half and have less expenditure; disseminate scientific culture promoting greater integration of C&T (culture & technology) between universities and businesses. The emanometric technique to estimate the location, number and interfacial area of NAPL in saturated and non-saturated zone, has the advantage of locating and determining plumes of free phase even when the amount of VOC's (Volatile Organic Compounds) that reaches the surface is low or non-existent. In addition, the measurement techniques ²²²Rn are quite developed. The results obtained show that, similar to the other studies, the 222Rn soil gas presents an anomalous behavior in the area bounded by NAPL plume, being possible to note a significant deficit in the concentration of the gas in spots where the saturation by NAPLs is still critical. Therefore it is concluded that this tool is really promising, but we must be careful to evaluate the initial conditions of the area, as well as the type of...

Avaliação da espessura da mandíbula com relação à fixação interna rígida em osteotomia sagital: estudo anatômico

Purpose: Trying to provide more anatomical data to the oral and maxillofacial surgeons regarding to orthognathic surgery, specifically about sagittal split osteotomy, the authors accomplished an anatomical study in dry human jaws, measuring the thickness in four previously established points of the body and mandibular ramus, at the usual spots used for the internal fixation by screws. Material and Methods: The authors also use the data collected to evaluate if there are significant differences between the group I (human dry mandibles with teeth) and group II (edentulous human dry mandibles). Results: For the group I the authors found the following results: x1 = 14,48, x2 = 14,94, x3=12,82 and x4 = 9,41, being the x2 the thickest point, and the least thick the x4. However in the group II, the found medium values were: x1 = 13,38, x2 = 13,08, x3 = 11,63 and x4 = 12,18, being the thickest point in that group the x1 and the least thick x3. The coefficient of simple correlation between the variables (group I and II) revealed a value of 0,6194, being this difference no significant at the meaning level of 95%.

Conservative treatment for amelogenesis imperfecta: a case report

Amelogenesis imperfecta is a hereditary condition that can alter the thickness, color, and shape of tooth enamel. Recent adhesive materials and techniques have provided less invasive treatment options. This case report presents the treatment of a patient whose anterior teeth had color alterations, white spots, pits, and shape defects. Using a more conservative technique, the mandibular and maxillary anterior teeth were restored using veneer direct composite restorations. After 6 years, the restorations demonstrated no deterioration, and no pathology was seen in association with the rehabilitation.

Variable assessment of wing colouration in aerial contests of the red-winged damselfly Mnesarete pudica (Zygoptera, Calopterygidae)

Wing pigmentation is a trait that predicts the outcome of male contests in some damselflies. Thus, it is reasonable to suppose that males would have the ability to assess wing pigmentation and adjust investment in a fight according to the costs that the rival may potentially impose. Males of the damselfly Mnesarete pudica exhibit red-coloured wings and complex courtship behaviour and engage in striking male– male fights. In this study, we investigated male assessment behaviour during aerial contests. Theory suggests that the relationship between male resource-holding potential (RHP) and contest duration describes the kind of assessment adopted by males: self-assessment, opponent-only assessment or mutual assessment. A recent theory also suggests that weak and strong males exhibit variations in the assessment strategies adopted. We estimated male RHP through male body size and wing colouration (i.e. pigmentation, wing reflectance spectra and transmission spectra) and studied the relationship between male RHP and contest duration from videodocumented behavioural observations of naturally occurring individual contests in the field. The results showed that males with more opaque wings and larger red spots were more likely to win contests. The relationships between RHP and contest durations partly supported the self-assessment and the mutual assessment models. We then experimentally augmented the pigmented area of the wings, in order to evaluate whether strong and weak males assess rivals’ RHP through wing pigmentation. Our experimental manipulation, however, clearly demonstrated that strong males assess rivals’ wing pigmentation. We finally suggest that there is a variation in the assessment strategy adopted by males
