Instrumento e método para adquirir sinais e imagens do trato gastrintestinal

This invention relates to an apparatus and method for improving detection by equipment used to detect magnetic susceptibility. The advantages provided are related to different factors, such as reduced instrumentation cost, performance in terms of stability and sensitivity, etc. The devices may be used, for example, to detect magnetic tracers and markers in the gastrointestinal tract of animals and humans. They can be used in research and/or for diagnostic purposes using information related to a variety of parameters of the gastrointestinal tract, such as, pharyngeal and oesophageal transit time, gastric emptying and motility, colonic motility, inter alia.

Distribuição espacial de atributos químicos do solo em área de pastagem e floresta

The knowledge on spatial distribution of soil properties by means of geostatistics is important as an indicator for a better soil use and management. This study aimed at evaluating the spatial distribution of soil chemical properties, in a forest and pasture area in Manicoré, Amazonas State, Brazil. Grids with 70.00 m x 70.00 m, with regular spacing of 10.00 m x 10.00 m, totaling 64 points, were established, and then soil samples were collected at the depths of 0.0-0.20 m and 0.40-0.60 m and had their chemical properties determined. Data were analyzed by using descriptive statistics and geostatistics, and the sampling density analysis was based on the coefficient of variation and semivariograms range. The mean and median values were adjusted to the closest values, indicating normal distribution, while the spherical, exponential and gaussian models were adjusted to the soil chemical properties. It was concluded that the geostatistics provided adequate information for understanding the spatial distribution. The forest area showed a higher spatial continuity and the pasture area a lower sampling density. The chemical properties showed differences in the spatial variability, while the range represented better the estimates for sampling density and spacing, in the forest and pasture area.

Atributos químicos e matéria orgânica em complexos florestais periodicamente inundados na restinga da marambaia - RJ

This study aimed to evaluate and characterize the chemical properties of soil organic matter under two periodically flooded forest formations on the island of Marambaia, Rio de Janeiro. These formations differ on the degree of soil water saturation, caused by the influence of water table, and in the (F1) formation presents the water table nearer the surface compared to the (F2) formation. Samples were collected in layers from 0.00 to 0.05, 0.05-0.10 and 0.10-0.20 m. The soil properties evaluated were: pH, H+ + Al+ 3, Ca+2, Mg+2, Na+, K+, P, N, total organic carbon (TOC) and base saturation (V%), humin carbon fraction (C-HUM), carbon of humic acid fraction (HAF-C) and fulvic acid fraction carbon (FAF-C). Statistically higher pH values were observed for F1. In F2 there are higher values of Mg+2, P, N and V% value. Correlation was found between the concentrations of Mg+2, N, humic acid and fulvic acid with water table in F1, and water table in F2 with Na+ and K+. Fraction C-HUM was more representative of the total organic carbon, followed by C-HAF and C-FAF. The TOC levels were higher in F1. The C /N ratio was lower in F2, with values ranging between 9 and 12, and F1 were found higher values of this relationship, ranging from 9 to 15. Among the pathways of formation of organic soils in both areas it appears that the major route for organic matter accumulation is the inheritance route.

Estudo clínico de prevalência de sinais e sintomas de disfunções craniomandibulares e contatos oclusais cêntricos em pacientes portadores de lesão labiopalatal

A clinical investigation was undertaken to find out the prevalence of craniomandibular signs and symptoms in a group of 11 patients with labiopalatal lesions. The number and distribution of occlusal contacts was evaluated through questionnaire, clinical examination and analysis of mounted casts in partially adjustable articulators in the position of maximum inter cuspation. The most frequent signs and symptoms were articular sounds and lateral pterygoid muscle tenderness to palpation followed by restriction of mouth opening and sensation of tiredness. The number of occlusal contacts was small, mean of 5 contacts per patient, and the site was considered as atypical, 62% of them were on inclined plane surfaces , suggesting occlusal instability. The frequency of signs and symptoms was low and they were of a mild character. The most prevailing signs of craniomandibular dysfunction - articular sounds, muscular tenderness to palpation and restriction of mouth opening - was noticed in only one of the patients

Mapeamento da situação educacional dos alunos surdos de munícipios brasileiros atendidos pelo curso de língua brasileira de sinais na modalidade à distância

Recent years have seen a movement toward school inclusion of children with special educational needs. In Brazil, there is the formulation of laws guaranteeing rights for disabled people, giving you free access to regular classroom complemented by specialized educational services. In the case of students with deafness, the Federal Decree No. 5626 of 2005, recommends that schools offer the Brazilian sign language as language support, and should take into classrooms, an interpreter. In this study we conducted a mapping of the educational situation of students with hearing loss of 35 municipalities. There was a mode of education in which deaf students are enrolled, and also the municipalities have organized the specialized educational services for such students. Data were collected through interviews with managers of 35 municipalities. The results showed that the vast majority of municipalities participating in the study opted for the enrollment of deaf students in regular class. Only a few municipalities managers reported the existence of classes and enrollment in special schools or even the existence of deaf students out of schools. It also found that all municipalities have organized the specialized educational services, like additional offering in the resource rooms. We conclude that despite the existing difficulties, the Brazilian municipalities are gradually adjusting to the prospect of inclusive education. Continuing education courses should be offered in order to prepare more teachers to work with diversity.

Alunos com surdez e o processo de inclusão: uma análise de discursos sobre sobre Língua de Sinais

The process of inclusion of deaf students at regular and specialized educational institution is a complex issue, which has the main point of discussion its specificity linguistic represented by Brazilian Sign Language. Whereupon, this research analyzed how the discourses of young students with deafness on this type of education at regular and specialized educational institution from a city situated in the State of São Paulo. The aim of this study was analyze the relations between the discourses of deaf students and their production conditionals, using the dimension of Discourse Analysis and the historical-cultural psychology. As parts of this research, were used four deaf students enrolled in schools belong in the city of São Paulo, which two schools are regular and two are specialized to deaf people. The collection instruments build themselves in observation of dialogue situations in classroom and interview semistructured. The interviews were made by video recording, researcher and an interpreter. The results showed that discourse of the student enrolled in the specialized school differs in relation to the ideals of bilingual education, in this case defended by users of the Brazilian Sign Language, fact not observed in the context of the regular school.
