Diagnóstico de gestação em cadelas: aspectos radiográficos e ultrassonográficos

The modernization of image equipaments associate to the veterinary professionals qualification allowed an advance in diagnosis veterinary medicine, and, consequently, in premature pregnancy diagnosis in bitches. Currently, owners and creators search for information related to pregnancy detection, fetal development and viability and litter size determination. Through diagnosis methods as radiology and ultrasonography, associated to clinics aspects, the diagnosis of early pregnancy become more acurated and precise, allowing more quality in the accompaniment of prenatal of these bitches. Ultrasonographic exams help the accompaniment of these pregnancies through of visuals recourses, which can supply information related to pregnancy detection, embrionary and fetal development, fetal viability e litter size determination through fetals mensurations. The radiographic study has as principal indication the fetal counting, and has been the most acurated for this analyses. It may be done after the da s after the luteini ing hormone surge, when occurs the fetal mineralization. Due to its importance in the present time and in small animals clinic, the objective of this study is to discuss the main radiographics and ultrassonographics aspects of the diagnosis of pregnancy in bitches

Classificação e mapeamento de áreas de risco de enchentes e inundações no bairro Jardim Inocoop - Rio Claro - SP

In the last few decades, Brazil has experienced an accelerated urbanization process in which many cities have grown in a disorderly way occupying environmentally fragile areas unsuitable for habitation. Anthropogenic actions such as high levels of impermeable soil, structural changes in watercourses, lack of riparian vegetation, illegal presence of trash and rubbish along the river banks added to irregular settlements in floodplains result in the rise of high risk areas. When accompanied by intense and prolonged rainfall phenomena, those areas have been the scenery of serious accidents such as floods. This study aims to classify the level of the risk of floods in the neighborhood of Jardim Inocoop, in the town of Rio Claro, São Paulo countryside, Brazil. One of the main technical support to tackle this issue is the identification and classification of the risks. In order to classify the risk level of flood in this case study, the methodology adopted was developed by the Ministry of Cities and Technology Research Institute, and take into account the arrangement of the hydrological scenario, vulnerability of households and dangerous process according to the distance of the houses from the axis of drainage. Therefore, the risk levels adopted to classify are listed below: very high (MA), high risk (A), moderate (M) and low risk (B). In conclusion, it is imperative to develop prevention plans in order to avoid or to minimize the damages caused by natural disasters. Therefore, the zoning of the risk sceneries remains as an important issue once it helps to identify the areas with high level risk of flood. Consequently, the occupation must be regulated where there is low or absent risk and it must be often forbidden where the high risk of flood is detected. Thus, the present study remains as an attempt to notify the risk of floods through its spatialization on a map, remainig...(Complete abstract click electronic access below)

Dinâmica da produção de serapilheira em diferentes sistemas de restauração florestal

The ecological restoration is an alternative to increasingly important for biodiversity conservation. However, actions need indicators to evaluate its effectiveness in restablishment ecological processes, including nutrient cycling. The objective of this study was to compare the annual litterfall from five different treatments for forest restoration, compared with a neighboring fragment of Seasonal Semideciduous Forest, in order to subsidize their management plans for ecological restoration. Litter traps of 0.25m² were used, and a total production was: 1700.6 Kg. ha-1.year-1(treatment 1), 7748.1 Kg. ha-1.year-1(treatment 2), 7120.8 Kg. ha-1.year-1 (treatment 3), 9254.5 Kg. ha- 1.year-1 (treatment 4), 7130.2 Kg. ha-1.year-1 (treatment 5) and 8876 Kg. ha-1.year-1 (fragment of Seasonal Semideciduous Forest - treatment 6). The leaf fraction was the largest contributor to the deposition of litter in all treatments. Litter served as a good environmental indicator that can be used as a tool to support management plans. Key words: Litterfall, forest restoration and Seasonal Semideciduous Forest

Avaliação da produtividade em áreas de campo sujo com diferentes históricos de fogo

Fire is a common event in different ecosystems and can both be caused by humans or have natural sources.. In many of these ecosystems, natural fires are an important factor that determines the vegetation. The reduction of tree cover by fire for example, resulted in the evolution of several species-rich ecosystems, dominated by C4 grasses. However, the fire caused by human actions may have greater intensity and lead to negative responses of vegetation, since man changed the fire regime in many parts of the world, such as in the Cerrado. The passage of fire can benefit herbaceous and woody seedlings that cannot compete with the dominant grass layer. It removes the dead biomass and litter (major components of the fuel load), opening up spaces within the grass matrix that allow the establishment of other species. After some time without fire, an increase in shrub cover and decrease herbaceous layer can be observed. One of the major consequences of the absence of fire in savanna and grassland ecosystems is the accumulation of flammable dead biomass (mainly composed of graminoids), which will probably be the fuel load of the next burning thus, fires will be more intense and hotter. Moreover, very frequent burns lead to a reduction in the frequency and density of grasses. Therefore, this study aimed to assess the quantity and quality of biomass in areas with different fire history (fire exclusion for 2 and 7 years) in areas of campo sujo in central Cerrado. Plots (1x1m) were established in both areas and all aboveground biomass of each plot was cut at ground level and put in paper bags in the field. In the laboratory, the material was sorted into live and dead biomass. In addition, live biomass was separated into different functional groups (graminoids, forbs, Vellozia spp, palm and shrubs). The material was oven dried for two days at 80°C and subsequently weighed. In both areas, we found a dominance of graminoid and dead biomass. The area...

Diagnóstico dos resíduos de serviços de saúde do grupo B gerados no município de Uberaba (MG)

The present work aimed to quantify the generation of group B health care`s residuals in places such as drugstores and pharmacies, in the municipality of Uberaba, MG, Brazil, as well as to identify their final destination in those places during the months of July and September, 2010. In order to also verify the medicaments generated by the whole community, some delivery campaigns were arranged to capture out-of-date medicaments at 3 drugstores. In this sense, all people who effectively looked for a pharmacy/drugstore to deposit the medicaments were invited to respond some questions, containing information about the name of the medicament, the pharmaceutical composition, the color applicable to the medicament and the expiration date. At the end of the period of research, 76 interviews were performed and 90 medicaments were observed (1.18 products per interview, in average). Results obtained suggested that pharmacies/drugstores located downtown tend to generate more medicaments than others located in the districts and periphery zones. Moreover, manipulation drugstores tend to generate more products than their conventional counterparts. Regarding the therapeutic classes, the anti-hypertensive medicaments represented the most substantial percentage of the medicaments delivered, accounting for 21,11%. However, the worst scenario tends to show that people usually do not know exactly how to discard this sort of product – about 65% of the people consulted discard chemical pharmaceutical residuals in the same place the domestic trash is thrown away – what may represent a serious risk in terms of contamination of the environment, so that a strong campaign towards the proper usage and discharge of medicaments should be strongly encouraged

Regeneração natural de mata ciliar em ecossistema de floresta estacional semidecidual: chuva de sementes e banco de sementes do solo

The knowledge of the dynamics of soil seed bank and seed rain is fundamental to understand the forest succession process, as well as for its conservation and restoration. This paper aimed at studying the role of the soil seed bank and seed rain in the dynamics of a riparian tropical seasonal forest fragment located on the hinterland of São Paulo State. The seed rain was studied by 30 litter traps installed at 50 cm from the floor, with an area of 50 cm x 50 cm. Between November of 2008 and October of 2009, 11364 seeds of 82 species belonging to 33 different families were collected. The deposition density of seeds was 126.27 individuals.m². With the data obtained from this research, the two seasons couldn’t be differed from each other hence 2009 was an atypical year considering the precipitation, which was constantly elevated. For the soil seed bank, fifty superficial soil samples will be taken at the end of both the rainy and dry seasons. The germination method was applied for the data analysis. It was observed a predominance of herbaceous habit species, with an average of 71% of the germinations in both seasons. The Sφrensen similarity index between the seasons was low (0,27). The density and species diversity were higher after the rainy season, unlike other published researches
