Participar Assinatura : software educacional de apoio à escrita do nome próprio para pessoas com deficiência intelectual

Monografia (graduação)—Universidade de Brasília, Instituto de Ciências Exatas, Departamento de Ciência da Computação, 2017.Este trabalho descreve o processo de desenvolvimento e testes de um software produzido para auxiliar pessoas com deficiência intelectual a aprenderem a assinatura do próprio nome. O sistema é um aplicativo para tablets com Android que pode ser complementar às práticas pedagógicas do professor. Ele colabora com a inclusão social, já que aproxima os estudantes da realidade dos dispositivos móveis, assunto muito importante nos dias de hoje. O software foi testado e validado em escola pública do Distrito Federal e obteve respostas positivas sendo bem aceito por professores e estudantes. Isso torna esta ferramenta de ensino uma aliada ao trabalho pedagógico já desenvolvido pelo professor, no processo de ensino do nome próprio.This paper describes the process of development and testing of software produced to help people with intellectual disabilities learn to sign their own name. The system is an application for tablets with Android that can be complementary to the pedagogical practices of the teacher. It collaborates with social inclusion, since it brings students closer to the reality of mobile devices, a very important subject nowadays. The software was tested and validated in a public school in the Federal District and obtained positive responses, being well accepted by teachers and students. This makes this teaching tool allied to the pedagogical work already developed by the teacher, in the process of teaching the proper name

Gesto e corporeit\ue0 nel IV canto del Purgatorio

Nel saggio viene fornito un esempio di come nella Commedia spesso i significati riposti nel testo non siano delegati soltanto all'espressione verbale, ma anche a quella corpore

Acquisizione in pista delle sollecitazioni su ramponi di battipista per la previsione di vita a fatica

Aim of the work was the design of instrumented trackbars to be mounted on rotating tracks of modern groomers for strain data acquisition in normal snow field operations: the knowledge of field load spectra and material fatigue properties allows for lightweight trackbars development. A rugged and compact acquisition system was adopted and applied to the trackbars in a protective case. Two trackbars were strain gauged with ten strain channels each, applied at two significant structural sections in correspondence of the support wheel and of the traction wheel, in order to measure the bending actions in two planes. Load acquisitions were performed to record the strain spectra for significant severe events and for typical use and compared with fatigue test data from a fatigue test bench developed at the company

Role of endogenous and exogenous nitric oxide on intestinal mucosa and microflora in the rat

In the present study the effects of exogenous and endogenous nitric oxide (NO) on intestinal bacteria and on the intestinal tissue integrity have been investigated in healthy rats and in rats receiving bacterial endotoxin (LPS). A segment of jejunum was taken in order to evaluate tissue damage and hematoxylin-eosin staining; microbiological studies were carried out collecting stool samples. Administration of LPS (5 mg kg-1 i.v.) induced a moderate jejunal damage, which was completely prevented by N-G-nitro-L-arginine methyl ester (L-NAME, 5 mg kg-1 s.c.), thus suggesting a damage of endogenous NO on the intestinal mucosa; sodium nitroprusside (SNP, 10 mg kg-1 os) reduced significantly jejunal damage induced by LPS. Endogenous NO produced by the administration of LPS resulted to be cytotoxic for all examined aerobic and anaerobic bacteria, while exogenous NO, released from SNP, showed an inhibitory effect only on Entero. faecalis and E. coli growth. From our data, it seems reasonable to conclude that high local levels of NO are required in order to observe jejunal damage and cytotoxic effects on aerobic and anaerobic faecal flora

Nutritional supplementation with copper in the rat. I Effects on adjuvant arthritis development and some in vivo- and ex vivo- markers of blood neutrophils

OBJECTIVE AND DESIGN: The aims of the work were: 1) to confirm the preliminarily observed anti-arthritic potential of a 200 ppm copper-supplemented diet in the rat: 2) to study the impact of the nutritional treatment and of the experimental pathology on neutrophil activity. ANIMALS AND CELLS: Two hundred female Sprague-Dawley rats were used. Polymorphonuclear leukocytes were isolated from these animals for the ex vivo studies. TREATMENT: Control-rats were maintained on a standard diet containing 5 ppm of copper. Supplemented-rats were kept on a diet containing 200 ppm of the metal. METHODS: Mycobacterium butyricum-induced arthritis was studied. Flame atomic absorption spectroscopy was used to assess copper and zinc levels. The "microplate-assay" technique was used to determine serum lysozyme concentration (lysis of Micrococcus lysodeikticus cell walls), as well as neutrophil O2- generation (superoxide dismutase-inhibitable reduction of ferricytochrome-c), and adhesion (activity of the membrane enzyme acid phosphatase). The results were statistically evaluated by the Student's t test. RESULTS: The nutritional copper-supplementation: 1) significantly inhibited the adjuvant-arthritis development (33% +/- 5, P<0.01); 2) did not modify lysozyme secretion or superoxide production; 3) significantly decreased the percentage of cell adhesion by an average of 41% +/- 19 (P<0.01). CONCLUSIONS: The copper-supplemented diet has an anti-arthritic effect which may be also primed by the effect of copper on the expression of the neutrophil cell-adhesion molecules
