Perfil fermentativo, estabilidade aeróbia e valor nutritivo de silagens de capim-marandu ensilado com aditivos

Com o objetivo de avaliar as perdas em silagem de capim-marandu produzidas com aditivos foram desenvolvidos dois experimentos. No experimento 1, objetivou-se conhecer o perfil de fermentação e a estabilidade aeróbia de quatro silagens: 1) forragem não tratada (Controle); 2) tratada com Lactobacillus plantarum e Propionibacterium; 3) tratada com Lactobacillus buchneri; e 4) tratada com 0,1% de benzoato de sódio. No experimento 2, foram utilizados nove novilhos castrados Nelore (PC de 350 ± 38,9 kg), alocados em três quadrados latinos 3 x 3 para avaliação do consumo e da digestibilidade das rações contendo 85,4% das seguintes silagens de capim-marandu: 1) controle; 2) controle com L. plantarum, Pediococcus acidilactici + enzimas fibrolíticas; e 3) tratamento 2 + L. buchneri. No experimento 1, as silagens apresentaram baixas recuperações de MS durante a fermentação (média de 86%) e os coeficientes de digestibilidade in vitro da matéria seca reduziram de 65,5% (momento da ensilagem) para 50,0% no 60º dia após o fechamento dos silos. No experimento 2, o valor médio de consumo das rações foi de 5,7 kg MS/dia (1,6% PC) e a digestibilidade de 51,6% e não diferiram entre as rações. As silagens apresentaram perdas acentuadas na fase fermentativa e o uso de aditivos não alterou essas perdas. A inoculação com bactérias não influenciou o consumo ou a digestibilidade das rações.

Perfil radicular da figueira sob efeito de níveis de adubação orgânica

O presente trabalho objetivou avaliar a distribuição do sistema radicular da figueira 'Roxo de Valinhos' em função da aplicação de níveis de adubação orgânica durante quatro anos. A cultura foi conduzida em Botucatu-SP, no espaçamento de 3 x 2 m, num solo classificado como Nitossolo Vermelho. Os tratamentos corresponderam a níveis crescentes de adubação orgânica com esterco de curral, conforme a recomendação de N para a cultura: testemunha (sem adubação), 25 %; 50 %; 75 %; 100 %; 125 % e 150 % da dose recomendada. A avaliação da distribuição do sistema radicular foi realizada 4 anos após a instalação da cultura, sendo que, de cada planta, foram retiradas quatro amostras a 0-40 cm de distância do tronco, na profundidade de 0-40 cm. As amostras foram submetidas à lavagem e secagem em estufa (65 ºC), para posteriormente avaliar a massa seca das raízes. O sistema radicular mostrou-se mais desenvolvido horizontalmente do que na vertical. O menor peso de raízes foi obtido sem esterco (43,3 g), e o maior, com 150 % da dose de N recomendada (177,7 g).

A tripla perspectiva: a vinda, a permanência e a volta de estudantes angolanos no Brasil

Este artigo é uma reflexão sobre o papel que as universidades paulistas e paranaenses desempenham no processo de formação acadêmica dos estudantes dos Países Africanos de Língua Oficial Portuguesa (Palop), em particular os angolanos. Essa formação na instituição de ensino superior propicia novos diálogos e novas sínteses identitárias possibilitadas por outras práticas culturais apreendidas no contato com alunos, docentes, funcionários, instituições acadêmicas e de pesquisa que ignoram a realidade vivenciada por eles em Angola. Constituiremos, assim, o cenário histórico-cultural; o percurso acadêmico e identitário do estudante angolano; o contexto estudantil angolano; a história recente desse país; o lugar do intelectual e do professor universitário; o papel e o uso da língua portuguesa no Brasil e em Angola no ambiente estudantil, familiar e na rua. Buscamos entender o imaginário do jovem estudante intercambista angolano que convive com os conflitos do estigma do migrante temporário e do estereótipo do refugiado de guerra.

Um estudo sobre o ensino-aprendizagem das demonstrações matemáticas

Demonstrations are fundamental instruments for Mathematics and, as such, are frequently used by mathematicians, math teachers and students. In fact, demonstrations are part of every Mathematics teaching environment, because Mathematics considers something true when it can be demonstrated. This is in contrast to other fields of knowledge that employ observation and experimentation to validate truth. This dissertation presents a study of the teaching and learning of demonstrations in Mathematics, describing a Teaching Module applied in a course on the Theory of Numbers offered by the Mathematics Department of the Universidade Federal do Rio Grande do Norte for mathematics majors. The objective of the dissertation was to propose and test a Teaching Module that can serve as a model for teaching demonstrations. The Teaching Module consisted of the following five steps: the application of a survey to determine the students‟ profiles and their previous knowledge of mathematical language and techniques of demonstration; the analysis of a series of dialogues containing arguments in everyday language; the investigation and analysis of the structure of some important techniques of demonstration; a written assessment; and, finally, an interview to further verify the principal results of the Teaching Module. The analysis of the data obtained though the classroom activities, written assessments and interviews led to the conclusion that there was a significant amount of assimilation of the issue at the level of relational understanding, (SKEMP, 1980). These instruments verified that the students attained considerable improvement in their use of mathematical language and of the techniques of demonstration presented. Thus, the evidence supports the conclusion that the proposed Teaching Module is an effective means for the teaching/learning of mathematical demonstration and, as such, provides a methodological guide which may lay the foundations for a new approach to this important subject

Tipos e consequências da violência sexual sofrida por estudantes do interior paulista na infância e/ou adolescência

Discutem-se os tipos de Violência Sexual (VS) sofridos na infância e/ou adolescência e suas vicissitudes, nas trajetórias sexuais de 236 adolescentes, de ambos os sexos, cursando o Ensino Médio no interior do Oeste Paulista que declararam ter sofrido um ou mais tipos de violência sexual. Dentre esses tipos, destacamos a Violência Doméstica Sexual (VDS), aqui definida como intrafamiliar. Nesse caso, observamos que, dentre os 236 adolescentes com histórico de VDS, 94 (39.8%) declararam ter pensado em suicídio e 39 (16.5%) disseram ter tentado, sendo que 35 (89.7%) deles se declararam heterossexuais (27 [77.1%] do sexo feminino) e 4 não-heterossexuais (3 bissexuais e 1 outro, sendo todos do sexo feminino). A maioria das vítimas finda por relatar o ocorrido aos amigos e responsáveis, mas pouco ou nada é feito, em termos de medidas protetivas a elas.

As práticas exitosas de leitura no ensino fundamental: vozes sociais de professores e de estudantes

The school is the social place which should provide the formation of critical readers. In this context, the role of the teacher is crucial when it comes to teaching reading. Thus, this doctoral research aims to explicit the reading practices evidenced from social voices of teachers and Fundamental School students from state public schools at RN that have successful results, according to IDEB 2009. Moreover, we seek to explicit, through the positions of teachers, the conceptions of reading underlying their reading activities, as well as elucidate the social voices related to teaching of reading that are present in the National Curriculum Guide for 9 years Fundamental School and in the Political-Pedagogical Projects of the educational institutions investigated. In order to accomplish this goal, we carried out observations in the classroom, applied questionnaires with teachers and students in the 9th grade of Fundamental School, in classes of Portuguese Language, and also performed dialogical meetings with the management and pedagogics schools teams. The theoretical foundation that guides the research comes from bakhtinian thinking (2009, 2010), which addresses the dialogical perspective of language and active responsive comprehension. Furthermore, this work is anchored in theoretical reflections of Antunes (2005, 2009) and Geraldi (2003, 2006, 2010) about the reading and writing in the country, which contribute to the resizing of the teaching and learning process of Portuguese Language. This study belongs to the field of Applied Linguistics, which investigates language as social practice in the context of learning mother language or in contexts where relevant questions about the use of language are evidenced. The parameters of qualitative research in a social-historic perspective are adopted seeking to understand the school context by the subjects involved in research. The research corpus is composed of: (i) information constructed through the use of questionnaires with teachers and students; (ii) information constructed from the observed lesson and dialogue with management and pedagogical teams; (iii) a set of selected information, i.e., empiricism built through documentary analysis of the National Curriculum Guide for 9 years Fundamental School (CONSELHO NACIONAL DE EDUCAÇÃO, 2010) and the Political- Pedagogical Projects of the investigated schools. The analysis of the sayings of teachers and students suggest reading practices from various texts, in particular, from the literary sphere, in activities involving discussions, reading and reading comprehension exercises, interviews, songs, seminars organizations, concerts, dramatizations, literary weeks, among other practices. Furthermore, these analyses reveal that teach Portuguese Language requires commitment, responsibility and satisfaction, as well as more grounded theoretical principles, which make teaching practice more efficient. The research also reveals that the success of the teaching-learning process occurs by virtue of the involvement of school s segments in the educational process, creating therefore a network of responsibilities. In this sense, this research may contribute to the production of knowledge that can guide and enrich the teaching and learning of reading, envisioning a pedagogical practice constructed from the relationship with the other, i.e., from the dialogism which provides formation of young people that exercise their citizenship

Apropriação de novas mídias por estudantes universitárias

It is an investigation that seeks to reveal, record and analyze the process of appropriation and use of digital media by university students, aged between 40 and 60 years. Interested in studying how changes are perceived in the educational sphere for students Whois have gone through liberal/traditional school, ie, effected the first contact with technological devices media as adults, in the university. This investigation sought to contribute to the knowledge on the use of new learning strategies imposed by digital media by recording and analyzing the reports surveyed sample. Allowed to know the cultural universe of these women, revealing the context in which receive mediated messages and uses that maré these learning strategies within their daily academic life. Gathered in this work, reflexions guided by studies of media reception and role played by digital media as builders images and facilitators in knowledging acquisitions, it was chosen to work two main theorical notions: communication media and digital inclusion. As the research methodology, it was used the exploratory descriptive technical together with other appropriate tecniques. In ordem to approach the problem can be observed two phases: a quantitative one, which was used an investigative procedure, a survey data with closed questions; and a qualitative phase, which was used to collect data through a diary from situations encountered in the classroom. The main objective of analyzing how digital media are received, appropriated and used by university women has been fulfilled and it is remarkable that they access with dificulty and can not be considered included digitally. The results show that the problem of these agents is not the access, there are was of appropriation of digital media offered at IES, and it was possible to note that they seek to integrate to the technological world, and they even have devices that can insert them on this world. Insertion in cyberculture sets up the ability to find a favorable way to be aware of reality and production of knowledge and liberating and dignifying practices, in this case refers to an appropriation of citizenship through the field of technological devices offered as a perspective that they can interact

Perfil demográfico e condições sanitárias dos idosos em área urbana do Sudeste do Brasil

São apresentadas séries históricas de indicadores demográficos e sanitários para a população com 60 anos e mais do Brasil, Estado de São Paulo e Município de Araraquara, de porte médio. em 1991, os idosos eram 7,8% da população brasileira e 9,7% de Araraquara, superando em número as crianças menores de 5 anos (8,9%). Aumentou o peso relativo do segmento com mais idade (70 anos e mais), que já representa 40% do total, assim como o índice de urbanização dos idosos, 93,7% no Estado e 96,3% no Município, acima da média da população em geral em 1991. As principais causas de morte são as doenças do aparelho circulatório (40% do total de óbitos) e os neoplasmas (15%). São sugeridas medidas para a assistência à saúde dos idosos: a) expansão da capacidade atual de atendimento, através do treinamento gerontológico de médicos generalistas e enfermeiros da rede pública e privada; b) incremento das atividades educativas já existentes, dirigidas aos idosos, profissionais da saúde e educadores do ensino médio; c) incremento do programa de visita domiciliar aos idosos e criação de hospital-dia para evitar internações necessárias e garantir a manutenção dos baixos níveis atuais de institucionalização em asilos (0,7% em Araraquara). A existência de pelo menos 35% dos idosos de Araraquara, com acesso à assistência privada à saúde, reforça a importância da inclusão desses serviços nos programas locais de saúde da terceira idade.

Saúde física e emocional de cuidadores da cidade de Santa Cruz-RN: perfil epidemiológico e fatores associados

Taking care for an impaired elderly is a hard and costly task that could affect directly the caregiver health. The purpose of this study was to evaluate the physical and mental health of elderly caregivers from the city of Santa Cruz-RN and analyze the potential correlated factors through an observational analytic design of a crosssectional. A multidimensional questionnaire was used to evaluation of the social demographics characteristics and those related to the care activity, as well as the caregivers´ physical and mental health. It was realized a descriptive analyze using frequency distribution and measures of the central tendency and dispersion to description of the caregivers. To verify the magnitude of the association between the variables was used the bivariate analysis through the Pearson and Spearman correlations and qui-square test. To evaluation of the association of the correlated factors to the adverse outcome with the caregivers´ physical and mental health was made a multivariate analysis by logistic binary regression and multiple linear regression models. The final sample was constituted by 304 persons, mostly women with a mean age of 50.3 ±16.8 years. The principal factors related to the physical health were age, stress and life satisfaction. Be a male caregiver, caring for a little while the elderly with cognitive deficit and not been spouse were related to worse mental health. Have worse physical health, high stress, depressive symptomatology, burden and low levels of satisfaction were also related to the mental health. After adjust through multiple linear regression was observed R2 values of R2=0,21 for Stress, R2 =0,17 for Depressive Symptomatology, R2 =0,21 for Burden and R2 =0,16 for Satisfaction. The attainment of the factors associated with caregiver´s health can help in the elaboration of specifics politics witch the goal is the integral attention to the elderly and his caregiver. The inability of continuous taking care could result in adverse outcomes such as institutionalization, impairment and death

Cargos comissionados da administração pública direta do Rio Grande do Norte: análise comparativa entre o perfil profissional dos cargos comissionados com vínculo funcional e sem vínculo funcional

The professional profile of public administrators in Brazil is changing very rapidly in recent years, seeking to meet the principle of efficiency by public agencies at all levels. The admission of the permanent government employee under the Public Administration is by competition, however, commissioned positions are free appointment of managers, which allows effective participation of external experts according to their respective standards and norms. In this context, this dissertation seeks to understand the main characteristics of the profile of the occupants of commissioned positions in Direct Public Administration of the State of Rio Grande do Norte, noting the differences between those with functional link with the have nots. For this study, by data collection and content analysis, a mapping of the administrative structure of the Government of the State of Rio Grande do Norte was done, i.e., the organization of the Executive Branch, which is regulated by the Complementary Law no. 163/1999 and its amendments, which consists of 53 (fifty three) entities, these 29 (twenty nine) are agencies of the direct administration and the remaining 24 (twenty four) comprises the indirect administration. With the collected data, analysis on the number of commissioned positions of each organ of the State of Rio Grande do Norte and information on education, age, length of service, gender and functional link with the direct administration was carried out. Data were available from SEARH in June/2013, when they totaled 58,733 (fifty-eight thousand seven hundred thirty-three) servers, these 2.15% (two point fifteen percent) occupy commissioned positions, corresponding to 1,262 commissioned positions under the Direct Administration, below the national average of 4% (four percent). Of total commissioned positions 64.7% (sixty-four point seven percent) have no functional link with the direct administration, while only 35.3% (thirty -five point three percent) have functional link. It was noticed that there are no clear and specific criteria for the appointments of commissioned positions in the State. They occur freely, as provided in the State Constitution. Another conclusion is the importance of Public Administration define and improve their capacity, competence and efficiency in the delivery of public services. For that it is necessary to invest in their workforce composed of permanent employees and commissioned positions to define the appropriate professional profile
