Uso da grade aradora superpesada, pesada e arado de discos na incorporação de calcário em profundidade e na produção de milho

Este trabalho teve o objetivo de avaliar o efeito dos modos de incorporação de calcário na correção da acidez no perfil do solo e na produção do milho. Para tanto, foi conduzido um experimento em Latossolo Vermelho Distrófico, textura argilosa, em Uberlândia - MG, no período de maio de 1995 a março de 1997. O delineamento experimental foi em esquema de parcelas subdivididas. As parcelas principais foram constituídas pelos modos de incorporação do calcário: grade aradora pesada (14 discos de 0,86 m) e grade niveladora (60 discos de 0,56 m); arado de disco (4 discos de 0,66 m) e grade niveladora; grade aradora superpesada (14 discos de 0,86 m) e grade niveladora; as subparcelas foram as doses de calcário dolomítico: 0; 6 e 9,2 t ha-1. O modo de incorporação do calcário afetou a eficiência da calagem no perfil do solo. A gradagem pesada não foi adequada para a incorporação do calcário. A aração com arado de disco mais gradagem niveladora teve desempenho satisfatório, atingindo até 0,20 m de profundidade. A gradagem com grade aradora superpesada proporcionou maior uniformidade e profundidade de incorporação, com neutralização da acidez do solo até 0,30 m de profundidade. O milho respondeu linearmente à aplicação do calcário, e o modo alternativo de incorporação pela gradagem com grade superpesada proporcionou maior produção.

WHO disability grade does not influence physical activity in Brazilian leprosy patients

Disability caused by leprosy may be associated with stigma. The aim of this work is to describe the degree of disability, quality of life and level of physical activity of individuals with leprosy and to identify possible correlations between these factors. Ninety-seven patients from two referral centres were studied. A complete medical history was taken and the World Health Organization degree of physical disability classification (WHO-DG), the International Physical Activity Questionnaire (IPAQ) and the Medical Outcome Study 36-item Short-form health Survey (SF36) were applied. The mean age of patients was 51 +/- 14.9 years old; participants were predominantly men, married, unemployed, had concluded treatment and had had lepromatous leprosy. The WHO-DG and the level of physical activity (P-value = 0.36) were not correlated. The WHO-DG showed that 72.2% of patients had disabilities, 37-1% of whom performed vigorous physical activities. No significant association was observed between the WHO-DG and the domains of the QoL SF-36 except for functional capacity (P-value = 0.02); the physical capacity is generally 'very good' when individuals have no disabilities and 'bad' with severe disabilities. In conclusion, the WHO-DG of leprosy patients does not affect the level of physical activities or quality of life except functional capacity. There is no significant association between physical activities and quality of life in these individuals.

Evaluation of sixth grade primary schoolchildren's knowledge about avulsion and dental reimplantation

Dental trauma, particularly tooth avulsion, is a frequent cause of tooth loss in children, adolescents, and young adults. The avulsed tooth should be immediately reimplanted in its alveolus. This procedure can be performed by anyone at the accident site and not only by dental surgeons. Therefore, the purpose of this study is to evaluate the knowledge of sixth graders of the city of Aracatuba, SP, about dental avulsion and tooth reimplantation through a structured and standardized survey. Our sample consisted of 778 students. The data collected was processed using the program epiinfo 2000. Most students were around 12 years of age and 94.5% related to practice some kind of sports. Results demonstrated that the possibility of tooth reimplantation after dental avulsion is not acknowledged among these students and dental traumatism was associated to caries, toothache, and use of orthodontic appliances. Only 18.9% of the students associated dental traumatism to an impact trauma; 3.6% would store the tooth in milk, and 3.1% believed the tooth could be reimplanted by anyone present at the accident site. In summary, the results show an overall the lack of knowledge about dental traumatism and highlight the need of special programs designed to educate school-aged students about emergency procedures to handle cases of dental traumatisms.

Negative Even Grade mKdV Hierarchy and its Soliton Solutions

In this paper we discuss the algebraic construction of the mKdV hierarchy in terms of an affine Lie algebra (s) over capl(2). An interesting novelty araises from the negative even grade sector of the affine algebra leading to nonlinear integro-differential equations admiting non-trivial vacuum configuration. These solitons solutions are constructed systematically from generalization of the dressing method based on non zero vacua. The sub-hierarchies admiting such class of solutions are classified.

Alfabetização de jovens no 6º ao 9º ano na perspectiva freireana: uma intervenção educativa para a vida na escola e no mundo

By showing how the problem of illiteracy is present among adolescents 11-14 years of age, attending school regularly, and realize how much this problem affect your life not only in school but also in their participation in society, it has set the aim of this research to alphabetize and write the lyrics registered adolescents of elementary school (6th to 9th grade) in a public school, by the Paulo Freire alphabetization method. The type of research that best responds to the proposed objective was action research with a qualitative approach. The data obtained from this research were analyzed in three topics: the search and selection of generating words, technical literacy and consciousness of each generating words (encoding and decoding of the situation experienced this situation with critical weight, pragmatic), and in the end, the analysis of the production of genre personal letter. The survey results indicate that, indeed, it is possible to write the lyrics and literate adolescents with Freirean literacy method. Also indicate the need to continue this work with the subjects of this research to develop linguistic and discursive skills to dominate the genre studied, both in the phenomenon of literacy, as in the write the lyrics. The results also point to another need, which is the extension of this research work in the community and other schools of the city, who have this problem of having teenagers in Elementary Education II, without being literate, as an alternative to overcome this major problem of illiteracy
