Geofísica aplicada no diagnóstico preliminar do antigo lixão do município de Rio Claro - SP

The issue of solid waste disposal and urban growth are conflictive, since the areas where old uncontrolled refuse disposal were away from the city today are incorporated to the urban area population. Thus, now population is closer to the degradation of contaminants coming from waste disposal, and, in some cases, these areas become housing subdivisions. This work aims to support the diagnosis of a former landfill in the municipality of Rio Claro (SP), using geophysical methods through resistivity anomalies. In order to develop the diagnostic, it was utilized water and soil analysis of a preliminary report and techniques of vertical electrical sounding and electrical profiling. The areas influenced by the garbage presented less resistivity than the one of the natural subsoil. Through the interpretation of results, the local potentiometric map was elaborated, as well as a map of calculated resistivity. The interpretation of these products indicated a disagreement between the groundwater flow and the current topography, leading to an identification of a preferential direction of the contamination plume in the NE-SW. These observations prove the applicability of geoelectrical methods in areas of former waste disposal with little information.

Diagnóstico ambiental das nascentes do Córrego dos Macacos – município de Álvares Machado/SP

Environmental diagnosis fits in analysis social-spatial organization insofar it contributes to understanding past and present aspects of how a territory works as well as enables the creation of statements for future ordainment. In this context, the present study aims at contributing with data for creating recovery and environmental preservation projects for the basin of Macacos‟ stream‟s headwaters, located in the north of Álvares Machado county in São Paulo state. To achieve this purpose, the main characteristics and existing uses in the basin have been analyzed and its main environmental problems were identified in the data and information collected in journals, field work and interviews with dwellers from the interested area and local government authorities. On this way, a diagnosis of the environmental state of the studied area was performed considering its specific issues regarding the natural and physical process as well as human influences. From the analysis carried out it was possible to identify environmental impacts on different levels resulting from the conflictuous relation between uses and occupations and the natural dynamics of the studied basin.

Diagnóstico ambiental de atividades de mineração com ênfase em olarias no município de Rio Claro (SP)

The environmental diagnosis of any area affected for mining activities contributes in a positive form for the analysis of the characteristics of the environment, biological and social, thus being able to establish control parameters. The clay extration for red ceramics promotes the environment degradation as any another one cultivates of mineral goods, but in lesser scale, which had to the dimensions of potteries. Being thus, some decurrent environment characteristics of the clay extration had been inquired clearly used for potteries located in the city of Rio Claro, SP. For this, the followed method was the cadastre of these areas and potteries in created tables, searching, with this, the contribution for the involved people in the extract activity of related potteries and the facilitation in the visualization of the main problems, necessities and proposals for each one. It could be perceived that the environmental diagnosis of the areas had in common presented referring points to the places where if they find the activities. The same ones are located in the region the northwest of Rio Claro and well next one to the others. Moreover, they have in common, referring characteristics to the process of manufacture of bricks. In common, all the responsibility for the administration and course of the activities competes to the proper families, since the administrative part, even though to the process of manufacture of the bricks. Moreover, from the comment of the areas through field work, the prominent use of diverse areas in the region for the clay extration is noticed, making with that the region has great importance in the regional scene.

Métodos diagnóstico de Hiperadrenocorticismo canina

The Hyperadrenocorticism is a disease that occur in dogs between mead to old age, is associated with the higher level of glucocorticoid that result in a corporal reaction. To make a diagnostic of this disease is necessary have a good history and physical examination, the principals complains of the proprietary are polyuria, polydipsia and polyphagia, in some times abdominal enlargement and lethargy. In the physical examination is observed this abdominal enlargement, hepatomegaly, alopecia, in some cases pyoderma and difficult respiratory. From this documents is possible determinate the differential diagnostics and with the tests find the diagnostic of the disease that the animal have. The base methods are hemogram, biochemical, urinalysis, radiographs and ultrasonography it’s possible do tomography and magnetic resonance too. There are confirmation methods too, they are very important, because the others not have documents necessary for the final diagnostic. Those are Urine cortisol to creatinine ratio, dexamethasone suppression test with high dose or low dose and ACTH stimulation test. Despite those tests have high sensibility and specificity, they can result in false positive or false negative, this is one of the causes to do the base methods and together make the veterinary doctor find the solution of the diagnostic and do the adequate treatment

Simulação de contaminação de sedimentos e águas subterrâneas por gasolina e álcool: um estudo de monitoramento de variações das propriedades físico-químicas

Geophysics studies in areas impacted by petroleum derivatives describe abnormalities of both low and high electrical resistivity (the opposite of electrical conductivity), confirmed as contaminant phase by chemical analysis: this contradiction can be explained by degrading processes that naturally occur and create sub products that can change the environment conductivity. Monitoring the variation of the parameters mentioned serves as a comparative basis to the variation in geoelectrical parameters, which identified the correlation between the same contaminant parameters and the difference between their behavior studied apart, as well as its relations with the biodegradation process. The results are applied to the fuel distribution and storage sectors, leading to the diagnosis and monitoring of possible groundwater contamination scenarios, and the knowledge of the area exposure time to the contaminant, besides the better remediation alternative and impacts control. Among some conclusions, the most significant are the decrease in conductivity over time, so as the increase in Eh value in the gasoline contaminated tank, as well as the decrease in the pH value in the second tank with ethanol, which can be attributed to its degradation. Comparing the variations in both tanks, it is evident that Eh, pH and electrical conductivity do not behave temporally in a similar way, although some correlations between Eh and pH can be related.

Diagnóstico da pesquisa em biodiversidade no Brasil

Biodiversity is a result of millions of years of biological evolution, and is the component of the system which supports life on our planet. Besides the intrinsic value of each species, all of them as a whole, as well as of the interactions among the species, and their interaction with the physical and chemical environment, result in ecosystem services vital for supporting life on Earth. Because of that, the science of biodiversity is largely recognized as a priority area of scientific investigation both in developed and developing countries. In Brazil, the research on biodiversity can be divided in three parts: 1) discovery and characterization of biodiversity – including marine and human-altered landscapes – systematics and taxonomy; 2) understanding the functioning of ecosystems and environmental services, including in marine and human-altered landscapes; 3) bioprospecting of the chemical diversity of the Brazilian biota.

Diagnóstico ambiental em área com vazamento de combustíveis por meio da integração de dados geofísicos e geoquímicos no município de São Manuel - SP

The contamination of the physical environment occurs as a result of the lack of planning and inadequate management of hazardous products. Due to the difficulty of the characterization and study of soil and groundwater, the contamination has been long neglected. The characterization of these areas by research techniques through direct methods such as physical and chemical analysis, are widely used in the diagnosis and monitoring. However, despite presenting quantitative results, this method is not representative in spatial terms. The purpose of this work is to bring geophysical complementation with the diagnosis, bringing the spatial element for the detection of the contamination plume. In the study area, there was a railway accident in 1999 in which three wagons fell and spilled 240,000 L of diesel onto the soil. The main objective is to assess the presence of contaminants in the residual phase and dissolved in the subsurface, using the technique of Electrical Tomography (ETR), understand the effects of natural attenuation process in the degradation of hydrocarbons and changes in electrical properties in soil and groundwater. The results allowed the definition of three distinct patterns of resistivity region with presence of dissolved phase, set in a historical chemical analyzes: low values (> 60Ω.m) associated with the presence of hydrocarbons in an advanced stage of degradation, intermediate values (260Ω.me 511Ω .m) indicative of coexistence of residual hydrocarbons and dissolved phase, and high values (> 1000Ω.m), which reveal the prevalence of residual phase with incipient degradation, possibly in high toxicity concentrations for effective action of biodegradation processes. The diagnostic of areas with potential accumulation of residual phase can subsidize the planning of remediation techniques and promote the complete decontamination of the area

Lombalgia equina: diagnóstico e tratamento

Low back pain is considered a major cause of lameness and performance decay, but identify the location of the lesions and quantify the intensity of pain is difficult because often the most obvious clinical sign, in some cases, is not the pain itself, but, low athletic performance. The diagnosis and treatment of this disease are associated with a high cost and have a strong impact on the equine industry, since it results in direct economic losses. The diagnosis of low back pain is made through physical examination and additional tests, including radiography, ultrasound, thermography and blockades. Major injuries causing back pain in horses is the contact or overlap of the spinous processes, supraspinous desmitis, osteoarthritis of the articular processes, vertebral body lesions and myositis. Therapeutic measures used in the treatment of these diseases are systemic inflammatory steroid, local infiltration, acupuncture, chiropractic, physical therapy, changes in training and surgeries.

Halitose na geriatria: diagnóstico, causas e prevalência

Halitosis is the unpleasant odor of exhaust air through the mouth and lungs. There are over 50 causes, and approximately 90% of cases, is of oral origin. May have physiological origin (stress, breath of morning, fasting, and inappropriate diets), local reasons (bad oral hygiene, bacterial plaque retained on the tongue and/or tonsils, lower production of saliva, gum disease) or systemic reasons (diabetes, kidney or liver problems, constipation, etc.). In the Third Age, this problem tends to increase significantly. Thus, the aim of this study was to detect the presence of halitosis in the geriatric group attended in the dental clinic of UNIRP, identifying their incidence and principal causes. The sample consisted of 48 volunteer patients aged 60 years or older and included more than 90% of patients treated in this age group. It was performed a anamnesis and physical examination. The intra-oral halitosis was detected using a breath meter (halimeter). In the group studied, approximately 54.16% had halitosis, 84.61% of these were users of the prosthesis. The tongue coating was present in 80.76% of individuals with halitosis. After brushing the tongue, 88.46% of patients with halitosis have had the initial index oral malodor decreased. Based on the results of this study it was concluded that factors as dental prostheses and tongue coating are critical factors in causing halitosis.
