Modelagem geoestatística das incertezas da distribuição espacial do fósforo disponível no solo, em área de cana-de-açúcar

Phosphorus is one of the limiting nutrients for sugarcane development in Brazilian soils. The spatial variability of this nutrient is great, defined by the properties that control its adsorption and desorption reactions. Spatial estimates to characterize this variability are based on geostatistical interpolation. However, inherent uncertainties in the procedure of these estimates are related to the variability structure of the property under study and the sample configuration of the area. Thus, the assessment of the uncertainty of estimates associated with the spatial distribution of available P (Plabile) is decisive to optimize the use of phosphate fertilizers. The purpose of this study was to evaluate the performance of sequential Gaussian simulation (sGs) and ordinary kriging (OK) in the modeling of uncertainty in available P estimates. A sampling grid with 626 points was established in a 200-ha experimental sugarcane field in Tabapuã, São Paulo State. The sGs algorithm generated 200 realizations. The sGs realizations reproduced the statistics and the distribution of the sample data. The G statistic (0.81) indicated good agreement between the values of simulated and observed fractions. The sGs realizations preserved the spatial variability of Plabile without the smoothing effect of the OK map. The accuracy in the reproduction of the variogram of the sample data obtained by the sGs realizations was on average 240 times higher than that obtained by OK. The uncertainty map, obtained by OK, showed less variation in the study area than that obtained by sGs. Thus, the evaluation of uncertainties by sGs was more informative and can be used to define and delimit specific management areas more precisely.

Prevalência do uso de chupeta e conhecimento dos educadores numa escola de educação infantil: estudo piloto

Pacifier use is very common among children, but despite being considered a harmless article, there is ample evidence of their misdeeds. Therefore, concern about its use is great for us who work in the promotion of breastfeeding. It is this delicate subject in schools because the child, in most cases, already goes to school with the habit installed. The pacifier use may interfere with speech aspect, because the child can come to the wrong talk, dental, dental occlusions, may cause bacterial contamination and encourage early weaning. The aim of this study was to investigate the prevalence of pacifier use among children of pre - school and knowledge of educators about the role of pacifier and its consequences. The research methodology was based on a questionnaire to teachers, monitors and direction and determine the prevalence of pacifier use with parents. According to the result, we developed an orientation for school. The results show that of the 57 children at the age of 4 months to 3 years, 50.88% used a pacifier, 92.98% and 96.49% used the bottle were breastfed. The guidance given after the data collection has clarified many questions for educators. We conclude that the methodology was effective because we can collect data addressing quantitative and qualitative questions and managed to get percentages on pacifier use and breastfeeding and student opinions, comments and more relevant phrases that emerged from parents and educators, complementing the result. Furthermore, through the data, it was possible to do an intervention. The results indicate that half of the children between 4 months and 3 years investigated makes use of a pacifier, so despite the advice given, it would be important to follow up these data over the next few years. We also conclude that a partnership is needed between parents and the school, because if the family does not help, you can not work in school guidance

Determinação da crítica razão esforço-pausa em Uchi-Komi no judô, com a utilização de deltas de variação de lactato sanguíneo e da escala subjetiva de esforço de Borg

In the competitive judo, the form as a trainer organizes the process of his/her athlete's training is a very important task for a good acting and a better use of the technical procedures. There is great importance in determining the exercise intensity for the judocas training due to the interest for the high income in several competitions, and few studies returned for this research area, involving those athletes' different physiologic conditions. Therefore, it is necessary to improve protocols of physical evaluation for this modality, increasing his/her applicability. The present study aimed at to verify the validity of a protocol of specific aerobic test of the judo (technique ipon-seoi-nague), no exhausting, adapted of the method of CHASSAIN (1986), using deltas of variations of the lactacidemia and of the Scale of Perception of Effort of Borg, in athletes well. The test adapted to the judo constituted of four exercise series with two efforts similar (double) of 180 seconds with one interval of 90 seconds among them. The series of exercises were accomplished in consecutive days. The intensities of the double tests were of 85%, 95%, 105% and 115% of the minimum lactato for each participant. This work used the technique ipon-seoi-nague, obeying the reasons effort-pause individualized for each athlete, that you/they correspond to the intensities of exercises proposed by the protocol of CHASSAIN (1986). In that way, the athletes applied a blow (maximum speed) and they rested some seconds, depending on the regime effort-pause of the session. At the end of each collection collection of blood (25NL) of each participant's earlobe was accomplished, seeking to measure the concentration of sanguine lactato. The collections were accomplished at the end of the first and of the second efforts, in each one of the series. For the analysis of the Perception of the athletes' Effort, the Scale of Perception...

Avaliação da tenacidade à fratura em juntas soldadas circunferenciais de tubulações de processo

This work aims to analyze the toughness of a welded joint in the presence of a crack through the analysis of maximum tension the material can withstand the presence of this type of defect, since a discontinuity is likely to occur in this type of joint and its detection and its design is simple, using non-destructive testing techniques. The study will be conducted through the CTOD test - Crack-Tip Opening Displacement, with type specimens SE (B) - Single Edge Bend taken from a weld in the L-C position in relation to the length (longitudinal axis) of a test tube. The main idea is to simulate the welding conditions for the manufacture of industrial pipes, made in boiler shops (pipe-shop) within petrochemical plants. These pipes are often subject to operation with flammable and toxic subjected to high pressures and temperatures, where one can break the line can cause irreparable damage to the plant, the environment and the health of surrounding communities. With this study we evaluate whether the weld metal has the same properties as fracture toughness of the base material. This study shows the importance of using a qualified welding procedure for performing quality welds while maintaining the properties of the fracture toughness of the base metal. It was found from the results of tests using a welding procedure described for carrying out welding ensures mechanical properties very close to the base metal, which in terms of design is great, since one can ensure that the weld will the same characteristics of the base metal specified for the assembly of the pipe

Comparação de eficiências do uso de sistemas construídos de áreas alagadas (Constructed Wetland Systems - CWS), tipos ascendente e descendente, para tratamento de efluentes

Water is an essential element for life. The use of this element, to support the community, defines it as water resource. This feature is being misused and degraded by the dumping of highly contaminated effluents. The impoverishment of its quality poses a risk to human consumption. The necessity to manage this resource, treating the wastewater properly, requires the constant improvement of treatment systems. Another need is to adjust the cost of systems to the demands of communities with less financial clout. This study aimed to adapt and understand the systems of wetlands, improving its efficiency, in an attempt to collaborate with the enrichment of this technology. The practical evidence, with lab-scale prototypes, assembled in ETE Piracicamirim with urban sewage effluent contributed to highlight the problems and operating system design. The bibliographic review showed that several studies had effectiveness for treatment. But it was evident the need for better understanding of dimensioning definitions that better attempted to the answers into the project. Moreover, standardization of system conditions for the specific wastewater treatment is an interesting field, identified, for future studies yet contribute to environmental engineering and sanitation

Emoção e afetividade na aprendizagem: breve revisão bibliográfica

This work has as its theme the role of emotions and affectivity in learning, particularly in science learning, being developed from a literature review. We start from the idea that learning occurs through changes in the neural networks of each individual and that these changes are caused by a combination of genetic and biological factors also influenced by emotions and affectivity. We seek information on the functioning of the human brain, highlighting the neuroanatomy and neurocognition, to understand how the brain processes information, including the feelings and emotions experienced by the individual. Once we try to understand which roles are assigned to the feelings and emotions in different learning theories, emphasizing the cognitive and humanistic theories. Finally, we found some more recent contributions to the understanding of the learning process, to the field of neuroscience. We were led to conclude that there is great scope for research in applied neuroscience to education, since the work, especially in the national literature are still scarce
