Reação do solo e disponibilidade de micronutrientes, em solo de textura média, tratado com lodo de esgoto e cultivado com milho

The evaluation of micronutrient availability in agricultural soil treated with sewage sludge was developed in Field with maize cultivation on a Dystrophic Red Latosol. The experiment used a randomized complete block design, with the treatments in a split-plot scheme, in time, with six doses of sewage sludge (main-plot treatment) in relation to the five sampling periods for the soil (subplot treatment), with four replications. The sewage sludge was applied in the superficial layer (0-20 cm). The micronutrients Fe, Cu, Mn and Zn were extracted from the soils using a DTPA (diethylenetriaminepentaacetic acid) solution. The same micronutrients were analyzed in the plant tissue after the nitric-perchloric decomposition of the maize samples by spectrometric atomic absorption. The results showed an increasing amount of Fe, Mn, Zn, Cu, Cation Exchange Capacity (CEC) and a decreasing pH in the soil. The increasing doses of sewage sludge increased the Fe, Mn, Cu and Zn availability in the soil solution, and the uptake amount by maize plants were always greater than the control values.

Os usos da mídia em aulas de Educação Física escolar: possibilidades e dificuldades

The media through images, sounds and information influences the way students interpret reality. This way, there is the need for the school to reflect on these issues and create teaching strategies to take advantage of this apparatus. The objective of this research was to analyze some possibilities of a proposal that addressed the content body culture through reports published by the newspaper Folha de São Paulo in Physical Education classes. The data indicated the media as a good teaching resource for classes of this course, since the students considered enriching classes for learning.

Secreção na orelha média em lactentes ocorrência, recorrência e aspectos relacionados

Objective: The present study aimed at evaluating the occurrence and recurrence of middle ear effusion and possible associated factors in the first two years of life of 190 newborns and infants, participants in the interdisciplinary prevention, detection, and intervention program at the Clínica de Educação para Saúde of Universidade do Sagrado Coração. Methods: Newborns and infants were monthly submitted to anamneses, otoscopy, behavioral hearing assessment using sound instruments and pure tones (pediatric audiometry) and tympanometry. Results: The results revealed that 68.4% of infants presented one or more episodes of middle ear effusion during their two first years, with more recurrence among males. Peak occurrence was between four and 12 months of age and, the earlier the first episode, the higher the probability of recurrence. Greatest incidence was during May and August. It was found that, of the variables investigated, the period of exclusive breastfeeding actuated as a protector factor. With respect of risk factors, it was observed that passive smoking, gastro-esophageal reflux and respiratory allergy were related with the recurrences of effusion. Conclusion: Findings revealed the importance of periodic auditory follow-up for infants during their first two years of life, considered to be the critical period of auditory system maturation, during which sensory deprivation can be responsible for damage to the development of speech, language and other auditory abilities. © 2007 Sociedad Chilena de Pediatría.

Técnicas de correlação no delineamento de feições rodoviárias em imagens de baixa e média resolução

This paper presents a method for the sequential road feature delineation from digital images. It is based on a feedback loop between extrapolation and refinement steps of a given road centerline point, using in both steps correlation techniques. Firstly, a previously extracted road centerline point is linearly extrapolated, resulting in an approximate position. Secondly, this approximate position is corrected by comparing gray level profiles extracted perpendicularly to the extrapolation direction. This strategy is then repeated to allow the entire road centerline to be extracted or a stop point to be found. In order to initialize the extraction process, the operator needs to supply a starting point plus direction and width. Experimental results obtained from the application of the method to real image data are presented and discussed in this paper.

Descrição do conceito de deficiência a partir da mídia cinematográfica: uma análise comportamental

This work pointed out forming elements from the conception of special necessities that the media show the audience by the movies. An expression description has established special needs and they were identified as keywords on a search of movies (1994-2004) which were analyzed by two observers, according to a script. The results showed that 33 of the movies selected, 39.9% were classified in the ramacategory; 64% shows the disability as organic nature and 57% with predominant clinic diagnoses. Many labeled practices were identified (85%) and few accessibilities options (76%). In 85% of the movies the disability is said a manifestation of problems with few (58%) professionals intervention. The results are discussed by the media role on the concept formation of disabilities, offering interaction models with important role on social practice specification or unsuitable to the relation with the diversity and to the culture.

Unidade amostral para determinação de massa média de frutos em lichieira em sistema orgânico e convencional

The experimental unit of measurement is a suitable technique to estimate the average character in evaluation, and experimentation should be well understood and executed, because the precision characterizes the quality of the inferences of the results. This research aimed to analyze the possibility to obtaining the quantity of fruit required for sampling of lychee plants, to determining the average mass of the fruits, with less sampling error. One hundred fruits were collected, in a hectare, in two cropping systems, conventional and organic, being one fruit per plant. From the data of fruit mass was used the Excel® to calculate the average fruit mass and number of fruits samples needed to represent the area of the producer. The results show that to achieve a sampling error of 10% for determining the average mass of fruit, 400 fruits should be collected for organic system and 370 for the conventional, while for 20% sampling error, it is necessary to collect 250 fruits per hectare in organic system and 220 in the conventional.

Interação de um aluno com paralisia cerebral com colegas de classe durante atividades ludicas

The study aimed to examine the quality of interpersonal relationships developed between a child with cerebral palsy (CP) and his classmates during group play activities carried out in the classroom and during recess. The participants of the study were a boy with clinical diagnosis of quadriplegic CP, his teacher and classmates. Data collection was carried out by means of a structured interview with the teacher and of video recording the child with CP interacting with his classmates in play activities. The interview data analysis was carried out using qualitative procedures and the video recording was analyzed using a category system. The results showed that the teacher perceived the child with CP to be interested; he participated in play activities and interacted successfully both with familiar partners and with all classmates in general. On the other hand, the analysis of the video recorded activities showed that even though interaction did in fact occur positively, the child with CP remained mostly an observer of the activities rather than an active participant, possibly due to the gap between the child's possibilities and the requirements imposed by the activities underway in the school setting.

Livros didáticos de ensino religioso: Análise da construção da polêmica no discurso da mídia

This text aims to identify the discursive relations and the mechanisms used by sources - discourses gathered at press and specialized sites - in composing of viewpoints presented about the religious education textbooks and, a result of that, of controversial relationship built thereafter. The theoretical foundation of this work rests largely on the concepts of global semantics and constitutive intermisunderstanding (MAINGUENEAU, 1997, 2008) and discursive heterogeneity (AUTHIER-REVUZ, 1990, 1998). The research corpus consisted of four texts, three of which were published in 2010 and another in 2011, two reports and two opinion articles about the subject. From our analysis, we could see the construction of a controversial relationship between a discursive formation that challenges the teaching of religion in Brazilian public education, on the grounds that benefit the Christian faith and, moreover, one that supports the continuation of this practice and consider it important for the formation of the student and also as a promoter of diversity and equality.
