Implantação de aterros sanitários: Comparação de métodos de seleção de áreas

Historically, the incorrect waste disposal has been related to epidemics which resulted in thousand of deaths. Despite the efforts to develop sanitary disposal methods in the 19 century, even today, uncontrolled dumps are often found in undeveloped countries. These places are responsible for environment pollution and for several diseases. The process of adequate waste disposal begins with the selection of suitable landfill areas, based on environmental characteristics. The goal of this research was to compare two methods of landfill site selection: the first one developed by IG-SMA (1999), and the other by Basílio (2001). Both methods were developed and applied in the same area - region of Campinas, São Paulo State, Brazil and this fact explains the choice for them; the comparison was made by superposing maps. Despite the same geographic area, the result was very different and few areas in common were found; IG-SMA (1999) obtained more suitable areas than Basílio (2001). This has been attributed to scale, criteria and attribute differences and, as a conclusion, Basílio (2001) was considered more restrictive than IG-SMA (1999).

Comparação de métodos para determinação da estabilidade de agregados por vias seca e úmida em diferentes sistemas de uso e manejo do solo

The purpose of the work is to evaluate the stability by dry and humid of theaggregate in different systems or the use and management in Argissolos: agricultural, pasture and torest utilization. This work was realized in agricultural property, in Anhumas city, SR Several analyses including percentage of the aggregate (by way of dry and humid); the weighted mean diameter of the aggregate calculation and statistic analysis. Conclusion: the organic matter content of the A horizon of the soil under forest is 64 % more than the soil under pasture and 79 % more than the soil under annual crop; the WMDA of the aggregate obtained by dry and humid ways of the horizon A and its mean value for the soil decrease in the following sequence: PVAd - forest > PVe -pasture > PVd - annual culture, respectively, with the following values: 1.33560 and 1.445496 (D), 2.81114 and 2.351380 (H); 0.66748 and 1.011830 (D); 2.79642 and 1.624250 (H); 0.32468 and 0.993775 (S), 1.25808 and 0.983135 mm (H); the two methods are equally sensitive to reveal the effect of the soil use and management; the organic matter provides additional stability to the aggregates submitted to humid sieving and clay to the dry sieving: the WMDA obtained by dry and humid ways are statistically different for the soil profiles.

Comparação dos efeitos da romifidina e de uma emulsão de amitraz na sedação e na atividade locomotora espontânea de eqüinos

Amitraz (AM) and romifidine (RMF), two alpha-2 adrenoceptor agonists, produce sedative effect and decrease spontaneous locomotor activity (SLA) of horses. The behavioral effects and sedation after intravenous injection of RMF (0.06mg/kg) or AM 0.1mg/kg (AM 0.1) or AM 0.4mg/kg (AM 0.4) were compared in horses. RMF caused head ptosis (HP) until 45 min. The lower AM dose induced HP from 45 to 60 minutes and from 120 to 150 minutes, and the higher dose induced HP until 180 minutes. Data concerning changes in SLA were not conclusive. RMF or AM 0.4 caused a greater sedation than AM 0.1 until 20 min. After 20 minutes, the sedation caused by AM 0.4 was greater than that of RMF or AM 0.1. Romifidine caused consistent sedation until 45 minutes. The amitraz emulsion produced a dosedependent sedation until 180 minutes. Comparing to romifidine, the emulsion of amitraz induced a more substantial sedation. At dosages and dilution applied, amitraz is an effective sedative for horses.

Clonidina como medicação pré-anestésica em facectomias: Comparação entre as doses de 100 μg e 200 μg

BACKGROUND AND OBJECTIVES: The objective of the present study was to evaluate the degree of sedation, intraocular pressure, and hemodynamic changes with premedication with low doses of oral clonidine, 100 μg and 200 μg, in outpatient cataract surgeries. METHODS: This is a randomized, double-blind, clinical study undertaken at the Universidade Federal de São Paulo with 60 patients of both genders, physical status ASA 1 and 2, ages 18 to 80 years. Patients were separated into three groups: placebo, clonidine 100 μg, and clonidine 200 μg. Intraocular pressure, heart rate, and blood pressure besides assessment of sedation were measured before and 90 minutes after the administration of clonidine. Sedation levels were classified according to the Ramsay sedation scale. RESULTS: Patients who received placebo and 100 μg of clonidine did not show reduction in heart rate, while a reduction in heart rate was observed in patients who received 200 μg of clonidine, and this difference was statistically significant. Patients who received 200 μg of clonidine also had a reduction in systolic and diastolic blood pressure (p < 0.05). One patient who received 200 μg of clonidine developed severe hypotension, with systolic pressure < 80 mmHg. Patients treated with clonidine had a reduction in intraocular pressure (p < 0.05). Ninety minutes after the oral administration of placebo and 100 μg and 200 μg of clonidine, 25%, 60%, and 80% of the patients respectively were classified as Ramsay 3 or 4. CONCLUSIONS: Clonidine 100 μg can be indicated as premedication for fasciectomies, being effective in sedation and reduction of intraocular pressure, without adverse effects on blood pressure and heart rate.

Soluções nutritivas no desenvolvimento do crisântemo cultivado em vaso

Although the information about nutritive solution for potted chrysanthemum is still incongruent, the objective of this work was to evaluate the effect of nutritive solutions in the development of Miramar chrysanthemum cultivated in pots at FCAV-UNESP, Jaboticabal-SP. The experiment had a randomized block design with split-plot evaluation and treatments corresponding to four nutritive solutions consisting of commercial fertilizers (S1, S2, S3, S4) evaluated at 0, 14, 28, 42, 56 and 70 days after rooting (DAE), with five replications. The plant height, leaf area, number of leaves, stem diameter, total dry matter mass of aerial part and roots; number and diameter of inflorescences, and physiological indexes of growth analysis were evaluated. The nutritive solutions did not interfere significantly in stem diameter, number and diameter of inflorescences and dry matter of roots, although S3 and S4 provided the highest plants, leaf area, number of leaves, total dry matter of aerial part. The physiological indexes showed that plants presented an accelerated growth from 14 to 28 DAE with S4 and S3 solutions and therefore they were considered the best solutions.

Comparação entre hipertensão autoreferida e pressão arterial casual e presença de fatores de risco em funcionários da saúde Bauru e Jaú

Model: Prevalence study. Objectives: To evaluate the presence of self-reported hypertension to compare with blood pressure measurements. Besides, this work investigated health information level of workers and if the job position has any influence on blood pressure (BP). Methods: This study evaluated 349 health workers (44±10 years old) from Bauru and Jau cities, who answered some questions about history of health condition, use of medicines, past surgeries as well as social, scholar and physical conditions and had their blood pressure measured. Each subject selfreported as normotensive or hypertensive. Values of systolic ≥ 140 mmHg and/or diastolic PA ≥ 90 mmHg were considered elevated. Among the health workers evaluated, 198 were submitted to anthropometric and biochemical evaluations. Values are presented as means ± SD and frequency of distribution. It was used T-student test (p<0.05). Results: From all workers evaluated only 16% self-reported as hypertensive, which 56% presented high BP, however 91% used to take antihypertensive medicines. Among the 84% who self-reported as normotensive, 24% presented high BP and 8% used to take medicines. Although most of the employees of each section self-reported as normotensive, more than a half presented high BP and which was more common in the health's section (76.3%). Conclusion: These results suggest that besides the majority of the employees self-reported as normotensive, an elevated number of health workers presented high blood pressure and used to take medicines inappropriately, which indicates that they did not have enough knowledge about their health. Furthermore, it was observed that Health Section presented the higher blood pressure values.

Comparação entre as necessidades energéticas prescritas e administradas a pacientes em terapia nutricional enteral

Objective: evaluating the adequacy, prescription and energy supply of enteral nutrition therapy in hospitalized patients. Methods: was performed a retrospective survey of the evolution of TNE protocol of 59 patients hospitalized in a general hospital in Marília / SP / BR. Data collected included gender, age, clinical diagnosis, anthropometric and dietary data related to the prescribed dietary formula, route and method of administration of the enteral nutrition, the daily volume prescribed and administered, the daily amount of energy required and offered in the diet, as well as possible complications. Body mass index (BMI), triceps skinfold (TSF) and arm muscle circumference (AMC) were used to establish the nutritional status of the patients. The adequacy of ENT was done according to the daily energy requirement compared to the average energy received during the daily use of ENT. Results: The average found to the BMI was 21.4 kg/m 2, and no differences were found comparing male and female. The data for TSF and AMC were different between genders (p<0.05) and suggest a more severe muscle mass in relation to adipose tissue. The averaged to the energy requirements was 1642 kcal/day but the average of energy prescribed was 1045 kcal/day and the amount offered was 1035 kcal/day. There was a significant difference between the necessity and the supplied energy offered through enteral nutrition (p=0.00) as well between the energy required and prescribed (p =0.00), both were shorter than the necessity. There was no significant difference (p>0.05) in energy supply, volume of enteral nutrition prescribed and administered among eutrophic, underweight or overweight patients. Conclusion: The results of this study indicate that the prescription and energy supply were not based on the needs of these patients, causing a significant energy deficit, which can lead to worsening of the nutritional status of the same. In hospitalized patients in use of ENT, the energy requirement must be made by a qualified professional within the multidisciplinary team, based on the needs of each patient.

Contaminação microbiana das soluções de processamento radiográfico: Risco de infecção cruzada

Objective: To evaluate the microbial contamination in samples of radiographic developing and fixing solutions, radiographic processing water, dental unit waterlines and dental office's external water supply. Methods: Samples of 50 private dental offices and 20 dental offices of the School of Dentistry de Araçatuba-UNESP were collected. The samples were subjected to neutralization of the residual inhibitory agents followed by pre-enrichment in peptone water and EVA broth and were inoculated in selective and non-selective culture media. The DNA of the samples was extracted and the presence of superinfectant microorganisms was evaluated by PCR. The differences in the prevalence of the microorganisms in the samples of the solutions were analyzed by repeated-measures analysis of variance for category data, while the Chi-Square and Mann-Whitney tests were used to evaluate the existence of associations between the total number of heterotrophic microorganisms and infection control protocols. The significance level was set at 5%. Results: Samples of radiographic fixing solution presented a remarkably less frequent contamination than radiographic developing solution and radiographic processing water. The latter exhibited microorganisms typically originated from the oral microbiota and human skin as well as microorganisms frequently found in dental unit waterlines. There was less contamination of radiographic processing water in the dental offices where the x-ray film packets were disinfected before processing or were covered by a plastic film. Additionally, all samples of dental office's external water supply were drinkable. Conclusion: Covering the x-ray film packets with a plastic film protection barrier was proven the best manner to reduce the contamination of the evaluated solutions.

Comparação entre metodologias para avaliar a idade à primeira concepção em éguas puro-sangue inglês

In Brazil, due to the breeding season for Thoroughbred, the reproductive data are normally truncate, since the breeders try to get animals that were born at the beginning of the breeding season in order to take their competitive advantages (more developed, mature and trained animals) compared to animals born later in the same breeding season. To analyze these data suitable methods should be used. Then, this paper aims to compare three methodologies: the method of maximum restricted likelihood, using MTDFREML, bayesian analysis without censured data by software MTGSAM and bayesian analysis with censured data by software LMCD, to evaluate age at first conception in thoroughbred mares, in order to verify its impact on the choice of stallions during selection. The database contained 3509 records for age at first conception (months) for thoroughbred mares. The heritability estimates were 0.23, 0.30 and 0.0926 (log scale), for MTDF, MTGSAM and LMCD, respectively. Considering all animals in the pedigree (6713), ranking correlations varied from 0.91 to 0.99. When only stallions were considered (656), those varied from 0.48 to 0.99 (considering different percentages of selected males) between evalua-tion methods. The highest changes in the general classification were observed when LMCD was compared to the other two methods. As the linear censured model is the most suitable for trait analysis with censured data, it was observed that censure information would lead to the choice of different animals during the selection process, when compared to the two other methodologies.
