Valor nutritivo da leguminosa Pueraria phaseoloides (Roxb.) Benth como alternativa na suplementação alimentar de ruminantes na Amazônia Oriental

Este trabalho foi realizado na Unidade de Pesquisa Animal “Senador Álvaro Adolpho” na Embrapa Amazônia Oriental, em Belém, Pará, para avaliar o efeito de quatro níveis de substituição (25%, 50%, 75% e 100%) da leguminosa Pueraria phaseoloides (Roxb.) Benth, no consumo voluntário e digestibilidade aparente da matéria seca (MS), proteína bruta (PB), energia bruta (EB), fibra em detergente neutro (FDN) e fibra em detergente ácido (FDA). O experimento foi de 14 dias de adaptação e sete dias de período experimental, utilizando-se dezesseis ovinos da raça Santa Inês, de dez meses de idade e média de 28 (± 2,44) kg de peso vivo, em delineamento inteiramente casualizado, com quatro tratamentos e quatro repetições. A substituição do quicuio-da-amazônia pela puerária na dieta influenciou o consumo voluntário e a digestibilidade aparente de todos os nutrientes, sendo descrito por função quadrática. Constatou-se um aumento quadrático nos consumos aparentes da FDN e FDA, contudo, com aumento do nível de leguminosa na dieta, foram observadas diminuições significativas nos teor de FDN quando foi fornecido o nível de 75%. A utilização da leguminosa Pueraria phaseoloides, proporciona maior disponibilidade de matéria seca na forragem e elevação do valor nutritivo, principalmente, proteína na dieta, promovendo aumento da produtividade animal. Níveis de substituição de P. phaseoloides, em torno de 100%, possibilitam maior consumo da matéria seca, matéria orgânica, PB e EB, enquanto que, o nível de 75% permite maior consumo das frações fibrosas.

Cálculo K: uma abordagem alternativa para a relatividade especial

In this paper we present an alternative approach due to Bondi for the special theory of relativity. During the development, we analyse the Bondi diagrams, visual resources from which we can take some information about the analysed systems, and we discuss the K factor of Bondi's theory, which is in the core of this work. We then discuss some of the main results obtained from Einstein's special theory of relativity such as the time dilation, spatial contraction and simultaneity of spatially separated events, besides the Lorentz transformations. We also show other two important results in physics coming from K calculus: the relativistic linear momentum and the total relativistic energy.

Educação continuada do catalogador na modalidade a distância: uma proposta alternativa

This paper presents a proposal for the teaching of cataloguing, emphasizing the problem-solving methodology. The proposal was designed for the distance-based continuing education of the professional cataloguer. It takes into account the challenges inherent to the development of interactive and inter-disciplinary tasks, as well as the development of directed self-education and critical consciousness of that professional, inasmuch as he becomes an active subject, manager of his/her own education.

Metadata Authority Description Schema (MADS): uma alternativa à utilização do formato MARC 21 para dados de autoridade

Introduction: Authority records interchange requires establishing and using metadata standards, such as MARC 21 Format for Authority Data, format used by several cataloging agencies, and Metadata Authority Description Schema (MADS), that has received little attention and it is a little widespread standard among agencies. Purpose: Presenting an introductory study about Metadata Authority Description Schema (MADS). Methodology: Descriptive and exploratory bibliographic research. Results: The paper address the MADS creation context, its goals and its structure and key issues related to conversion of records from MARC 21 to MADS. Conclusions: The study concludes that, despite its limitations, MADS might be used to create simple authority records in Web environment and beyond libraries context.

Uso de sistemas de comunicação suplementar e alternativa na Educação Infantil: percepção do professor

Augmentative and Alternative Communication Resources have proven to be helpful in the insertion of students with disabilities and complex communication needs into a variety of pedagogical activities and expand the skills and competencies of the teacher in the teaching-learning. The objective of this research was to identify the perception of teachers regarding the use of augmentative and alternative communication during an intervention program in Preschool. Participants were a special class of Preschool students with disabilities and severe communication complexity, along with their teacher and the researcher. For the development of this research, a Alternative Communication Program was applied. The teacher was provided with systematic guidance concerning language and communication. In a collaborative process, three children’s songs were selected according to the teacher’s pedagogical planning and adapted resources through Augmentative and Alternative Communication Systems. During the intervention program, assisted evaluations also took place immediately after the activities with the music. The data were collected in audio recordings. For data analysis, content analysis was carried out resulting in the outlining of themes and subthemes. Results indicated that the teacher identified that Augmentative and Alternative Communication Systems can to facilitate expression abilities of students with disabilities; that Augmentative and Alternative Communication Systems can be used by children in Preschool; and that resources adapted through augmentative and alternative communication systems should be in accordance with the specificities of students.

Programa de capacitação de famílias de crianças, jovens e adultos usuários de comunicação alternativa

This study aimed to enter a training program for family members of children, youth and adults who use augmentative and alternative communication systems in the context of alternative languages . The study included families in the age group of 25-65 years in the period 2010- 2012. The activities were held weekly with duration of one hour in a alternative communication laboratory. All activities were videotaped and after that, the verbal participants’ reports were transcribed. The obtained categories were analyzed according to the steps of the program. The results indicated that families realized: the necessity of graphics systems for communication; the importance of adapted materials; and the need to understand their children’s different skills. The study reinforced the need for systematic and continuous guidance for families, as well as highlighted the use of graphics systems in the context of language.

Sistema de Comunicação Alternativa na Interação de um aluno com autismo e seu professor

Individuals with autism are often unable to communicate through speech, and the ones that are able to speak sometimes cannot begin or to maintain a conversation. This article presents a case study that observed the communicative profile of a young student with autism interacting with his teacher during classroom activities using adapted PECS. The results demonstrated that the autistic student enhanced communicative initiatives in the interaction with his teacher, and the augmentative and alternative communication system was a facilitating tool used in the communicative learning process.

Efeitos da comunicação alternativa na interação professor-aluno com paralisia cerebral não-falante

Speech has been regarded as a social communicative modality required for building relationships in different contexts and cultures. Nevertheless, this is not always a readily available resource, especially for those who have developmental disorders. In this sense, Augmentative and Alternative Communication resources and strategies have been used by nonspeaking students with disabilities as useful tools to achieve greater social participation in different environments. Therefore, the present study examined the interaction between teachers and a student with cerebral palsy before and after the use of Alternative Communication strategies in the classroom. The study had a quantitative and qualitative nature and was designed as an intervention study. There were four main stages: 1) filming before the introduction of the resources in the classroom, 2) training the school teachers 3) providing technical assistance regarding the use of alternative communication to the child's teacher 4) filming teacher-student interactions using these technological resources. The interactions were transcribed and grouped into links. In this research, a link means the initiator's behavior directed to the exchange partner and the response in sequence from the interlocutor back to the initiator. It was found that the established interactions presented a maximum of four links, with greater frequency for episodes of 1st and 2nd links. After the intervention, there were different contexts with the presence of interactions up to the 6th link, often greater frequency for episodes of 1st, 2nd and 3rd links. In addition, the teacher showed a tendency to use symbols only as a tool for evaluating and teaching concepts. This perception changed as the teacher became familiarized with the Augmentative and Alternative Communication technology resources.
