The platelet blood count in laboratorial routine provides to the clinician important information about the hemostasis of the patient. There are many techniques described, however the gold standard techniques realized in hemocytometer spent a lot of time, making this technique impracticable in great routines. This research had the intent to evaluate if the automatic veterinary blood counter QBC Vet Autoread (R), whose results get five minutes to be ready, is capable to offer a trustworthy platelet count number. To this end, were evaluated the correlations among three different forms of platelets count in dogs: count in automatic blood counter QBC Vet Autoread (R), estimative in blood smear and the gold standard method by manual count in hemocytometer. The viability and confidence use of automatic blood counters of the medicine veterinary routine. Seventeen dogs were chosen randomly way, in the medical and surgical routine of HOVET-USP. The analysis revel high correlation between the hemocytometer and the estimative in blood smear (r=0,875) and between the hemocytometer and automatic blood count by QBC Vet Autoread (R) (r=0,939). Conclude that the platelet blood cont by QBC Vet Autoread (R), in addition to be fast, it's more truthful when compared with estimative in blood smear, although the latter one also had elevated correlation. However, morphological analysis through the smears cannot be dismissed because none of the other two techniques evaluated have the ability to assess platelet morphological changes.

Further to increase the wood yield, is important goal of forest tree breeding the adaptation of clones through diverse environment, especially for soil and climate. Perennial tree species such as eucalypts, have a long life cycle and the frosts can occur and to be their limiting source of cultivation. The aim of the study was to determine the genetic variability and the genetic correlations between selection ages of clones cultivated in the municipality of Palma So la, SC, Brazil, where frosts are common in the winter. A clonal trial was set up in 2008 in Palma So la, by statistical design of randomized complete blocks considering 29 clones, six replications, six plants per plot, and 3.0m x 3.0 m spacing. The silvicultural characters of total plant height, diameter of breast height (dbh), and wood volume were evaluated through 24, 36, 48, and 60 months old. The deviance analysis and estimates of genetic parameters were based on the REML / BLUP genetic statistical procedure. Significant differences were observed for all traits in the deviance analysis. High correlations and statistically significant between characters were observed, indicating that the early selection will provide significant gains. Part of the clones USP/IPEF 64, USP/IPEF 78, USP/IPEF 52, USP/IPEF 68, and USP/IPEF 74) are potential to be used into the breeding programs and in commercial stands into the studied frost regions.

The work is guided by the detailing of the Itajaí river basin, SC, rainfall dynamics at the annual, seasonal and monthly levels, allowing us to identify different responses that each location gives to the regional atmospheric circulation, particularly the rainfall. In this sense, we are aiming at approaching the concept of rhythm, which must be obtained at the daily level. The analysis at different climate scales was possible through isohyetal maps, trend lines, and Schroeder pluviographs. Moreover, we established the flow rate of the air masses by means of the Venn diagram. This data made it possible to assess the behavior of rains on that site and the reason why it is the stage of major flooding, as occurred in November 2008. The relatively mountainous topography combined with the frequent invasions of the Atlantic Polar Front, which often stop over the region, generate events of that magnitude, with high volumes accumulated in short periods of time. Such extreme events reinforce the idea of the search for the succession of types of weather to the detriment of averages that tend to abstract the reality

The Conservation in countrysides landscapes only it will be understood in the context of the habitat fragmentation that have been affected the species richness, abundance and distribution. We carried out a mammal survey in platation forest at São Paulo State and 8 we discussed the species richness comparing with others sites surveyed elsewhere. We investigate the landscape influence in the mammal species distribution through spatial analysis. The absence of primate species in plantation forests appear to be a pattern for this environments. The species richness was similar among areas and it was higher when there have contiguous native forest remnants. Moreover the landscape interference don’t appeared affect the mammal species distribution. In overview the landscape connectivity is ameliorate with forest plantation. However, those species more susceptible to extinction in fragmented landscape only can persist when there are contiguous forest fragments from the plantation forests. The management of plantation forests can improves the conservation value for medium and large size mammals species at countryside landscapes.

Increased demand for energy and the search for alternative energy sources are remarkable and current facts. The management of domestic solid waste is also part of the issue in view of the possibility of power generation in existing landfills, which could provide financial autonomy to the system of waste management and improve the environmental balance of landfills in Brazil, currently only used for final solids disposal. Landfill gas is a viable alternative energy source has been tested in landfills in the World and in Brazil. Thus, the research aimed to evaluate the percentage of methane (CH4) present in three sinks of gases from a landfill in the municipality of Rio Claro – SP (Brazil), and to estimate the potential methane generation over its life through the application of a mathematical model. As a result it was found that in general the percentage of methane present in the gases is significant, between 50 and 62%. It was also noted that waste with disposal time between 8 and 12 months already are in the methanogenic stage. Finally, there was a tendency to increase the generation of methane in the transition periods of rain and drought

The genus Brachycephalus is endemic to the Atlantic rainforest and is distributed mainly in the southeastern and southern Brazil. Currently, it has 17 recognized species, most of them, associated with mountainous habitats along the Serra do Mar and Serra da Mantiqueira ridges. Here we use an ecological niche modelling approach based on climatic variables, to assess the potential niche of the mountainous species of this genus. The model generated was then projected to future scenarios considering the last IPCC report, in order to estimate the impacts of climate changes on these species distribution. Results show a decrease in the total suitable area for the mountainous Brachycephalus species, as well as tendencies already observed for other organisms, such as, pole and upward migrations. A southern area on Planalto de Paranapiacaba increases in suitability for these species. We suggest special efforts on new surveys and conservation on the northern part of their distribution, once this seems to be the region more affected by climate changes on the projected scenarios

The wide territorial extension of Brazil derails the installation and maintenance of instruments for measuring solar radiation, which makes necessary the development and application of models that are able to estimate reliable and sufficient data for many different activities that use such data. And these, in most cases, are estimated from the Ångström equation. Based on this model, this project aimed to estimate the global solar radiation at Presidente Prudente-SP, Brazil, using daily data from 1999 to 2007. The solar radiation data have been extracted from the paper tapes of actinograph bi-metallic (Robitsch) daily records at the meteorological station in the Faculty of Science and Technology, UNESP. These tapes were scanned, resulting in digital images with x and y coordinates pairs (x = time; y = solar radiation, cal/min.cm²). The daily global solar radiation is the area under the curve of the image. This value has been calculated by computer algorithms. After the acquisition and calculation of the values needed to develop the Ångström equation have been determined the constants a and b, using linear regression between the values of Rg/R0 (solar radiation/solar radiation on a horizontal surface at the top of atmosphere), as ordered, and n/N (number of hours of sunshine/day length in hours) as abscissa. The slope of the line will be the constant b and the linear coefficient, the constant a. The estimated results were compared to the observed using the Kolmogorov-Smirnov test, realizing that the models can be accepted. So, the equation to aim the solar global radiation is: Rg = R0 (0,2662+0,3592 n/N)

The intensive development in the urbanization process implied a series of economic, social, and gradually, environmental transformations, essentially, since its intensification, which took place from the Industrial Revolution in Europe and North America. In Latin American countries, including Brazil, there was such acceleration in urban sprawl, only in the middle of the twentieth century, fomented by a peculiar industrialization, coming from the scientific-technical revolution, which occurred in developing countries. In this context, and with a lack of planning and an effective organization, cities of the dependent countries face an inordinate population growth and an unprecedented industrial swelling. Brazil, following this trend, presents several issues regarding the gaps in the provision of necessary infrastructure to meet the most basic needs of its population and the intense activity and anthropogenic effects on the environment. In this sense, environmental problems, related to air and water pollution, degradation and contamination of soil, paving roads, reduction of green areas, urban heat island, among others, reaching ever deeper into the Brazilian urban areas. It is important the analysis in this final project, the weather events related to episodes of strong winds and the events and the impacts to the population of Rio Claro (SP) in the period 2005 to 2010, basing themselves in Geographical Climatology and Urban climate studies. In this scenario, we found the prevalence of occurrences linked to falling trees in the study area, connected, at the same time, to the occurrence and to the absence of episodes of extreme events, with measurements of strong winds, showing a connection between the events and external facts to episodes of winds

The approach of the subject matter in this work relies on the fact that the reliability of methods for performance analysis of materials proves critical for the result. This work focused on the development and presentation of the methodology for lifting probability curves for fatigue test (SN) according to standard E739, this focus is justified by the fact that the results in fatigue test show considerable dispersion making it difficult to reading and interpretation of data, this dispersion arises because the phenomenon of rupture is strongly influenced by internal characteristics of the material, we can then have much data ranging from test to test. Thus we set out originally for a brief study of aluminum alloys in question, as well as the treatments to which they were subjected. We also studied the behavior of materials when subjected to cyclic loading, which configures process of fatigue failure, and even fatigue test method in question. This statistical analysis is based on the ASTM E739 standard, so its contents was studied in detail so that we could present in detail the methodology and raise SN curves for different aluminum alloy 7012 subjected to fatigue test. Data were collected from tests conducted in the department of materials from two samples of aluminum alloy 7012 solubilized and precipitated by different time intervals and assayed temperature fatigue-type traction-compression, these data were then analyzed and used to survey curves using the base as E739. After lifting the curve analyzed the characteristics of the test samples and their correlation with the test results. We confirmed the effectiveness of the method of statistical analysis by ASME E739, which allowed the reading of data without this method would be very difficult to have a reading and comparison of the results for the two types...

This work analyzed the loss of sensible heat from one fluid to be considered homogeneous heat distribution on a thermal reservoir with cylindrical geometries composite insulating layers. We studied two thermal reservoirs with a volume of 20 liters, and the first has a layer thickness of 75 mm of expanding polyurethane foam wrapped in the polycarbonate container and the second container has only layer thickness of 5 mm of polycarbonate, as insulation of fluid of the external environment. The experimental results are compared with theoretical results obtained through a calculation script, displayed and detailed during the work development, from the theory of energy balance. The maximum error introduced between the theoretical and experimental results were 3.5% and 1.4% respectively for the Boilers with or without a polyurethane coating

Brazil faces a complex problem in respect to municipal solid waste, having been in recent years an increase of its generation without the country there be adequate for proper disposal thereof. In many states , the percentage of waste destined improperly , ie , in dumps , landfills, send- outs , among others , is greater than that disposed in landfills , which would be the most correct way to be made. It can be argued that this discrepancy is due to the high cost of implementation and operation of the landfill, and the same need large areas with physical characteristics that suit their operations . When there is a provision in properly constructed landfills , municipal solid waste grounded generate gases with high potential energy through biochemical reactions during the anaerobic decomposition of organic material stored . Such gases can be used for power generation within the landfill or other economic means . To estimate the gas generation will be sufficient for such economic compensation , there are mathematical models that make estimating the amount of gas produced . These models calculate the energy capacity and generation , using parameters obtained based on the characteristics of solid waste , climate of the region where they are grounded and grounding time . Such models have been raised and studied so that it was possible to perform simulations that demonstrate the behavior of biogas generation related to the external conditions of the landfill that interfere with biological reactions within. The results show differences between the values obtained , it shows that the preparation of the models found and used in the simulations were allocated amounts for different parameters that determine this difference in the estimate . Therefore, to rule, the models have difficulty understanding this because there is no clarity in the formulation of the equations , and the definition of variables and parameters would require a detailed study to...

Pipelines are linear engineering works, designed mostly for transporting oil and its derivatives for long distances, furnishing even the farthermost zones of the country. Due to oil sector needs to ensure for the safety and conservation of its properties, several geotechnical studies are being held at the pipelines field, in order to preserve this important transportation, and also to prevent accidents, which might seriously compromise the environment and the population who lives around it. The OSBRA pipeline, who connects the city of Paulínia to the capital Brasília, is one of these engineering works that deserves to be pointed out. This research, performed at the Ribeirão da Prata Basin, was a pilot study conducted with the main objective of testing the current methodology efficiency, for future applications in the closest watersheds to the OSBRA pipeline. The objective of this research is to analyze flood wave and debris flow processes in a non-fictional watershed, by comparing two different kinds of methods: the first one based on simulation models (software ‘ABC 6’), and the other one by flood wave and debris flow susceptibility mapping. The results from the hydrological modeling were both hydrographs and ietographs that estimated values of outputs and infiltration. To construct the susceptibility maps were necessary three other maps: ground use and occupation maps, divided according to the different protection degrees that were offered to the ground; maps of dam locations in the area and physiographic compartimentation maps, divided according to the local geology. To complete the methodology, the results were collected from both methods for comparison. The obtained product for this methodology was series of data whose different susceptibility degrees to flood wave and debris flow could define the safest route for a pipeline crossing in this watershed...

The study of mathematical modeling assists in evaluation of the capacity of production and measurement of generation time of biogas in landfills, enabling the implantation of projects of energy generation from methane. Thus, the work aims, by simulating scenarios of potential methane generation in the landfill in Rio Claro, the use of field data from methane flow and waste grounded parameters as references for selecting values of k e L0 used to estimate methane generation model in LandGEM. As a result it was found that compared the characteristics adopted in the four scenarios recommended by the USEPA literature with those found in the landfill of Rio Claro (high amount of organic matter in the waste landed and daily practice of leachate recirculation), the scenario that apparently better represent the rate of methane generation is the scenario 01, with k = 0.7 and L0 = 96. Now, the adjustment of parameters in relation to the data field of methane flow, the value of L0 which best fits the methane generation from the landfill in Rio Claro is 150, while for k the line behavior that best represents the reality are values between 0.7 and 0.3. Regarding the parameters of the waste grounded, between the suggested values of k, 0,3 is most consistent with the intermediate level of biological degradation of the residue grounded, while L0 due to the biodegradability of the waste, a new value between 120 and 150 may be more appropriate for the study
