Estimativa da Radiação Solar em Presidente Prudente – SP nos anos de 1999-2007

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)

Validação dos parâmetros aeróbio e anaeróbio a partir de protocolo não invasivo aplicado ao exercício resistido - supino reto

The purpose of this study was to investigate the validity of critical force test from maximal lactate steady state (MLSS) during resistance test using straight bench press. Five healthy male volunteers aged (22.6 ± 2.88 years), weight (76.3 ± 11.49 kg) e height (182.6 ± 7.54cm), trained in resistance exercise, and performed four diferent test to determine: one maximal effort (1RM), critical force using the critical power model (force vs 1/time limit - 20, 25 and 30% 1RM). The CF was the linear coefficient and the anaerobic impulse capacity (CIA) was the angular. MLSS was determined using loads of 80, 90, 100 and 110% of critical force. Blood lactate samples were abtained at each 300sec between each stage of total 1200sec. Maximal 30s test (M30) was accomplished with load of 25% of body weight in SBP. The results showed that the 1 RM was 79.4 Kgf (± 16.98), CF 10.1N (± 2.25), CIA 1756.82 N.s (± 546.96) and the R² 0.984 (± 0,02). The MLSS occurs at 100% CF load. The lactate concentration at the MLSS was 2.2 mmol/L (± 0.77). Significant correlation was observed between MLSS and CF on SBP (r = 0.88 p = 0.05). In M30 the minimum, mean and peak power were (25.0 ± 4.9, 28.0 ± 4.9, and 30.0 ± 4.6 kgf.rps, respectively). The fatigue index was 18.0% (± 6,8). The M30 was significantly correlated with Ppeak and Pmean (r = 0.98 for both, p = 0.003). The CF means has been validated to predict the resistance training and the CIA show to be a representative anaerobic parameter in straight bench press.

Contagem automatizada de veículos utilizando segmentação estatística

In this work was developed a program capable of performing automatic counting of vehicles on roads. The problem of counting vehicles is using expensive techniques for its realization, techniques which often involve manual counting or degradation of the pavement. The main motivation for this work was the importance that the vehicle counting represents to the Traffic Engineer, being essential to analyze the performance of the roads, allowing to measure the need for installation of traffic lights, roundabouts, access ways, among other means capable of ensuring a continuous flow and safe for vehicles. The main objective of this work was to apply a statistical segmentation technique recently developed, based on a nonparametric linear regression model, to solve the segmentation problem of the program counter. The development program was based on the creation of three major modules, one for the segmentation, another for the tracking and another for the recognition. For the development of the segmentation module, it was applied a statistical technique combined with the segmentation by background difference, in order to optimize the process. The tracking module was developed based on the use of Kalman filters and application of simple concepts of analytical geometry. To develop the recognition module, it was used Fourier descriptors and a neural network multilayer perceptron, trained by backpropagation. Besides the development of the modules, it was also developed a control logic capable of performing the interconnection among the modules, mainly based on a data structure called state. The analysis of the results was applied to the program counter and its component modules, and the individual analysis served as a means to establish the par ameter values of techniques used. The find result was positive, since the statistical segmentation technique proved to be very useful and the developed program was able to count the vehicles belonging to the three goal..

Estudo para correção dos sensores da rede de monitoramento do campo elétrico em função do campo elétrico de tempo bom

A monitoring network of atmospheric electric field covering the Vale do Paraiba region was implemented. The sensors were located on different sites with different altitude and geographic topology. The present work reports the study carried on those sensors in order to verify the necessity of using some correction factor to the measured local electric field intensity due to effects of local environment. The measurements were done in continuous 24 hours per day with the data recorded on registers in each device accumulating information during a period of four months. The relation between the electric field values by each sensor was compared to the reference located on Sao Jose dos Campos city using the same period. In a graphical analysis using the local field intensity and the reference, the data were fitted to a straight line obtained by minimum square method. Variation up to 95% was observed between the field values in some sensors. Another method was proposed, comparing the mean values of the electric field in a function of time. The variation in some sensors reached up to 133%. We conclude that the variations are due to local atmospheric conditions and no correction factor is required on the electric field sensors

Métodos de estimativa de peso e altura na avaliação de desnutrição de pacientes com câncer

To calculate the estimated and actual height and weight measures in cancer patients, evaluate the correlation and concordance of these measures and to identify the malnutrition patients. 62 cancer patients, treated at the Amaral Carvalho Hospital (Jaú- SP). For classifi cation of nutritional status, the Patient-Generated Subjective Global Assessment, the Body Mass Index and the relationship with usual weight were used. For the estimated weight was used the algorithm Chumlea et al.7 and estimated height, the equation proposed by Chumlea et al.8 and Kwok & Whitelaw24. The Pearson Correlation Coeffi cient and the Intraclass Correlation Coeffi cient was calculated and simple linear regression was conducted. To compare the malnutrition detected by different methods, the Cochran’s Q test were performed. There was a strong and signifi cant correlation between the estimated and actual weight (r=0,95; CI95%=0,92-0,97; p<0,001) and excellent concordance (ρ=0,95). For height measurements, a signifi cant correlation was observed between the actual and estimated measurement the method Chumlea et al.8 (r=0,78; CI95%=0,66-0,86; p<0,001) and Kwok & Whitelaw24 (r=0,85; CI95%: 0,75-0,90; p<0,001). Concordance was “Good” (ρ=0,72) and “Moderate” (ρ=0,67) between the actual height and estimated by Chumlea et al.8 and Kwok & Whitelaw,24 respectively. There was a strong correlation between the actual and estimated weight and height measures. The reproducibility of the equation proposed by Chumlea et al.8 to calculate height was better. The nutritional status, the patients classifi ed as malnutrition was greater when using the Patient-Generated Subjective Global Assessment and the relationship with usual weight.

Quality of life of people living with HIV/AIDS treated by the specialized service in Vitória-ES, Brazil

The aim of this study is to establish the factors that influence the quality of life of people living with HIV/AIDS being treated at a specialized public service. The participants answered the questionnaire on sociodemographic conditions, issues related to HIV and daily habits. The quality of life was analyzed using the HIV/AIDS-targeted quality of life (HAT-QoL) instrument with 42 items divided into 9 fields: General Activity, Sexual Activity, Confidentiality Concerns, Health Concerns, Financial Concerns, HIV Awareness, Satisfaction with Life, Issues related to Medication and Trust in the Physician. Bivariate and multiple linear regressions were performed. Of the participants, 53.1% were women and had a mean age of 42 years. In analyzing the quality of life, the HAT-QoL domain with the lowest average was Financial Concerns (39.4), followed by Confidentiality Concerns (43.2), Sexual Activity (55.2) and Health Concerns (62. 88). There was an association between the variables: not being gainfully employed (p < 0.001), being mulatto or black (p = 0.045) and alcohol consumption (p = 0.041) with the worst quality of life scores. Inadequate socioeconomic and health conditions had a negative impact on the quality of life of people with HIV/AIDS.

Estimation methods of reference evapotranspiration (ETo) for Uberlândia -MG

One approach to verify the adequacy of estimation methods of reference evapotranspiration is the comparison with the Penman-Monteith method, recommended by the United Nations of Food and Agriculture Organization - FAO, as the standard method for estimating ET0. This study aimed to compare methods for estimating ET0, Makkink (MK), Hargreaves (HG) and Solar Radiation (RS), with Penman-Monteith (PM). For this purpose, we used daily data of global solar radiation, air temperature, relative humidity and wind speed for the year 2010, obtained through the automatic meteorological station, with latitude 18° 91' 66 S, longitude 48° 25' 05 W and altitude of 869m, at the National Institute of Meteorology situated in the Campus of Federal University of Uberlandia - MG, Brazil. Analysis of results for the period were carried out in daily basis, using regression analysis and considering the linear model y = ax, where the dependent variable was the method of Penman-Monteith and the independent, the estimation of ET0 by evaluated methods. Methodology was used to check the influence of standard deviation of daily ET0 in comparison of methods. The evaluation indicated that methods of Solar Radiation and Penman-Monteith cannot be compared, yet the method of Hargreaves indicates the most efficient adjustment to estimate ETo.
