Given the paradigm of inclusive education, the presence of students with autism spectrum disorder in regular schools has become more significant in recent years. Studies have revealed, however, deficits in academic participation of these students in these settings. Among the factors contributing to this phenomenon include poor teacher training and the lack of strategies to promote curriculum access. The aim of this study was to develop an instrument that would promote academic inclusion of a student with autism through procedures that could simultaneously empower the teacher. In this perspective, the study aimed to analyze the effects of an Individualized Educational Plan (IEP), developed collaboratively with teachers, on the academic and functional development of a student with autism in an early childhood education setting. Data were collected in a private school located in the city of Natal in Rio Grande do Norte, in the course of the academic year 2012. In addition to the student with autism, one teacher, a specialized educator, and four teacher aides participated in the study. The research used a single subject quasi-experimental design (AB) as well as qualitative methods of data analysis. The study was conducted in three phases: characterization, baseline and intervention. The first comprised interviews with the child´s parents and teachers, as well as the identification of two routines focus of intervention. In the second phase, the amount of time the student spent engaged in the selected routines during baseline was analyzed. In the third phase, the researcher prepared, collaboratively with the teachers, an individualized educational plan (IEP) for the student. Finally, the IEP was implemented by the teachers. The results indicated qualitative and quantitative changes in student´s participation in academic and functional tasks after the intervention program

This work aimed to study the reproduction and description of technique for digital sampling images during rats gait and determination of the sciatic functional index (SFI), through a glass walkway to obtain shoots with a digital camera. After controlled injury by strangulation of sciatic nerve, with 3mm of length, during 30 seconds, using hemostatic forceps, a group of 32 rats was performed 24 hours before the lesion which served as control and 24 hours, 7, 14 and 21 days after injury. The tests consisted in the filming and shooting each animal in order to observe the view from below (by a mirror to 45 degrees) and subsequently analyzed using the IMAGE-J program. Measures were taken from the lengths of the legs (right and left), and the distance between the ankle. In the analysis of IFC, values close to zero (0) suggest that the function of the sciatic nerve is still preserved and values coming from "less one hundred" (-100) indicate total loss of function. It was verified in this study that 24 hours before surgery the average SFI was -7.07 +/- 7.88 and 24 hours after injury these values rose to an average of -77.95 +/- 13.81, being about 10 times larger, where 78% of the animals showed 60 to 100% of functional loss in motor activity, demonstrated by the gradual recovery over the days analyzed, confirming the accuracy and effectiveness of the proposed methodology. These results suggest that studies can be conducted to simplify and reduce costs using the technique for digital images of footprints during rats gait in the laboratory.

To study plant growth and yield of cauliflower, two field trials were carried out: the first spring-summer (Oct. 07, 2006 to Jan. 28, 2007) and the second autumn-winter (Apr. 04, 2007 to Jul. 09, 2007). The experimental design was randomized complete blocks in 4 x 4 factorial design with three replications. The following factors: line spacing (0.6, 0.8, 1.0 and 1.2 m) and plant spacing (0.4, 0.5, 0.6 and 0.7 m). The used cultivar was cv. Verona 284. The characteristics, number of leaves by plant, diameter of stem, diameter of inflorescence, inflorescence mass and yield were evaluated. With the reduction in spacing, were observed lower numbers of leaves, stem diameter, diameter and mass of the inflorescence, but there was an increase in yield. The maximum yield (23 t ha(-1)) was obtained with 0.6 x 0.4 m, ie, in higher plant population (41,667, plants ha(-1)).

In maize (Zea mays L.), the inadequate nitrogen supply and planting density are considered limiting factors to the grain yield. The objective of this study was to evaluate the influence of different nitrogen levels and plant densities to the maize yield components and productivity. The experiment was carried out in the Cerrado region, located in the southern of the Maranhao State, Brazil, in a clay Oxisol (Ustox), cropped under the no-tillage system for six years. The randomized completed blocks experimental design with four replications was used, with treatments arrangement in a 5 x 4 factorial. The treatments were a combination of five doses of nitrogen as urea (0, 50, 100, 150 and 200 kg ha(-1)) and four plant densities (25,000; 50,000; 75,000 and 100,000 plants he). The grain number and mass per spike and grain mass per plant were improved by increased N and decreased plant density. Higher incomes of grains were obtained with adding concomitantly in N doses and in plants density. The maximum grain yield (11,9 Mg ha(-1)) was obtained with 120 kg ha(-1) of N and 83,000 plants ha(-1).

A compactação do solo tem causado decréscimos na produtividade de soja, e os valores de densidade do solo a partir dos quais a produtividade decresce são pouco conhecidos. Assim, este trabalho objetivou avaliar a produtividade de soja (cv. Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) 48) em relação à densidade relativa (Dsr) de Latossolo Vermelho textura média (LVd) e argilosa (LVef). em 2001/2002, foi realizado um experimento em casa de vegetação, com amostras coletadas nos dois solos na camada de 0,0-0,2 m, peneirados a 4,0 mm, adubados e compactados em camadas de 3,0 cm, em vasos de 20 cm de altura e 25 cm de diâmetro. Foram estabelecidos quatro níveis de compactação e dois de água no solo (tensão de 0,01 e 0,05 MPa), com três repetições. A soja foi semeada em novembro (duas plantas por vaso) e irrigada duas vezes ao dia. No segundo experimento, no campo (2002/2003), utilizou-se apenas o LVd que foi compactado por meio de passadas de trator com quatro pneus de mesma largura, estabelecendo-se cinco níveis de compactação, com quatro repetições. A soja foi semeada, em dezembro de 2002, no espaçamento de 0,45 m entre linhas e 20 plantas por metro. Foram determinadas a densidade do solo (Ds) e a Ds máxima pelo teste de Proctor, sendo a Dsr obtida por divisão da Ds pela Ds máxima. Na colheita, foi avaliada a produtividade de grãos. A Dsr ótima para a produtividade de soja, em casa de vegetação, foi superior no Latossolo Vermelho eutroférrico argiloso (0,84), comparada à do Latossolo Vermelho caulinítico de textura média (0,75), na tensão de água no solo de 0,01 MPa. No campo, a Dsr ótima para soja foi de 0,80.

The purpose of this paper is to identify the utilization of two models of orthotics used in the conservative treatment of rizartrose in patients/consumers that were referred by the medical clinic to the LAI (Laboratory of Integrated Accessibility). It describes this group s perception related to the functional aspects of the two models, evaluates the value of the product attributed by the patient/consumer and describes the importance attributed to each model. The research s objective consists in identifying which model this is preferred from the point of view by the patients that use either the dorsal or ventral models used in the conservative treatment of rizartrose . This work is then based on the exploratory research through the investigation of the bibliography available and in the research field. The research field used the case study methodology to investigate the phenomenon in the real context. The data were collected using a patient questionnaire during two times after the use of the dorsal orthotic and after the use of the ventral orthotic. The questionnaire was used to identify the relationship between the patients/consumers and the two different types of orthotics. A general descriptive analysis was used in order to verify the patient s abilities executing certain activities daily living using the dorsal and ventral orthotics, the product s functional aspects and its value from the patient s/consumer s point of view. The results show that the preference for the dorsal or ventral models is determined by the individual needs of each person. The results also show that other variables, such as the use of the orthotic on the dominant or non-dominant hand, play a role in the preferred model by the patient/consumer and need to be further investigated

The study analyzed the wood basic density effect in two Eucalyptus grandis x Eucalyptus urophylla hybrid clones (440 kg/m(3) e 508 kg/m(3)) on bleached pulp quality (fiber dimensions and physical-mechanical properties). The woods performance on pulping, bleaching and beating results were analyzed. The Kraft pulping was carried out in forced circulation digester in order to obtain 17 +/- 1 kappa number targets. The pulps were bleached to 90 +/- 1 using delignification oxygen and D0EOPD1 bleaching sequence. Bleached pulp of low basic density clone showed, significantly, lowest revolutions number in the PFI mill to reach tensile index of 70 N.m/g, low Schopper Riegler degree and generated sheets with higher values to bulk and opacity. These characteristics and properties allow concluding that bleached pulp of low basic density clone was the most indicated to produce printing and writing sheets. The bleached pulp of high basic density clone showed higher values of bulk and capillarity Klemm and lower water retention value when analyzed without beating. The bleached pulp of high basic density clone showed more favorable characteristics to the production of tissue papers.

This work proposes the specification of a new function block according to Foundation Fieldbus standards. The new block implements an artificial neural network, which may be useful in process control applications. The specification includes the definition of a main algorithm, that implements a neural network, as well as the description of some accessory functions, which provide safety characteristics to the block operation. Besides, it also describes the block attributes emphasizing its parameters, which constitute the block interfaces. Some experimental results, obtained from an artificial neural network implementation using actual standard functional blocks on a laboratorial FF network, are also shown, in order to demonstrate the possibility and also the convenience of integrating a neural network to Fieldbus devices

Estudou-se o efeito de diferentes embalagens de polietileno em figos cv. Roxo de Valinhos, sob condições de frigoconservação. Os frutos colhidos no início do estádio de maturação, foram limpos e selecionados, sendo após embalados em filmes plásticos de polietileno de diferentes espessuras, constituindo assim os tratamentos: 1(controle), 2 - PEBD com 6 µm de espessura, 3 - PEBD com 10 µm de espessura, 4 - PEBD com 15 µm de espessura, 5 - PEBD com 22 µm de espessura. Os frutos foram então armazenados em câmara fria com temperatura de -- 0,5 °C e 85-90 % de UR, por oito dias. As análises foram realizadas diariamente, avaliando-se os seguintes parâmetros: perda de massa fresca, aspecto visual, firmeza de polpa, sólidos solúveis totais (SST), acidez total titulável (ATT) e relação SST/ATT. Ao final, verificou-se que os frutos embalados em PEBD de 22 µm apresentaram maior firmeza de polpa, melhor aspecto visual, menores teores de sólidos solúveis totais, maiores níveis de acidez total titulável e menores valores na relação SST/ATT, quando comparados aos demais tratamentos. No parâmetro perda de massa fresca, todos os tratamentos foram estatisticamente superiores ao controle.

Seis cabras Pardas Alpinas com produção média de leite de 2,5kg/dia, foram distribuídas aleatoriamente em dois grupos de três cada, submetidas a termoneutralidade ou estresse térmico. Usou-se um delineamento estatístico crossover. Um período de adaptação de 28 dias foi seguido por quatro intervalos de 14 dias cada, durante os quais os animais sob estresse foram expostos à temperatura média do ar de 33,84ºC das 8 às 17 horas, incluindo radiação solar simulada das 10 às 15 horas. Na segunda semana de cada intervalo experimental amostras de leite individuais foram coletadas diariamente pela manhã e à tarde, adicionando-se conservador. No final da semana as amostras de cada ordenha foram misturadas formando-se amostras compostas nas quais foram efetuadas determinações de pH, acidez titulável, densidade e ponto crioscópico. Os resultados indicaram que os valores obtidos para densidade e ponto crioscópico são compatíveis aos encontrados por diversos autores em diferentes países. Constatou-se valor maior para densidade no leite ordenhado pela manhã, em relação ao da tarde, sendo que o intervalo desigual entre as ordenhas deve ter influído neste resultado. Não se verificou diferença estatística significativa para esta propriedade no leite das cabras em condições de termoneutralidade e de estresse térmico. Para o ponto crioscópico não se observou diferença estatística entre o leite ordenhado pela manhã e à tarde. Houve diferença estatística significativa para esta propriedade física entre o leite das cabras em condições de termoneutralidade e estresse térmico, sendo o valor médio maior, para as condições de termoneutralidade.

Complex network analysis is a powerful tool into research of complex systems like brain networks. This work aims to describe the topological changes in neural functional connectivity networks of neocortex and hippocampus during slow-wave sleep (SWS) in animals submited to a novel experience exposure. Slow-wave sleep is an important sleep stage where occurs reverberations of electrical activities patterns of wakeness, playing a fundamental role in memory consolidation. Although its importance there s a lack of studies that characterize the topological dynamical of functional connectivity networks during that sleep stage. There s no studies that describe the topological modifications that novel exposure leads to this networks. We have observed that several topological properties have been modified after novel exposure and this modification remains for a long time. Major part of this changes in topological properties by novel exposure are related to fault tolerance

This work holds the purpose of presenting an auxiliary way of bone density measurement through the attenuation of electromagnetic waves. In order to do so, an arrangement of two microstrip antennas with rectangular configuration has been used, operating in a frequency of 2,49 GHz, and fed by a microstrip line on a substrate of fiberglass with permissiveness of 4.4 and height of 0,9 cm. Simulations were done with silica, bone meal, silica and gypsum blocks samples to prove the variation on the attenuation level of different combinations. Because of their good reproduction of the human beings anomaly aspects, samples of bovine bone were used. They were subjected to weighing, measurement and microwave radiation. The samples had their masses altered after mischaracterization and the process was repeated. The obtained data were inserted in a neural network and its training was proceeded with the best results gathered by correct classification on 100% of the samples. It comes to the conclusion that through only one non-ionizing wave in the 2,49 GHz zone it is possible to evaluate the attenuation level in the bone tissue, and that with the appliance of neural network fed with obtained characteristics in the experiment it is possible to classify a sample as having low or high bone density

Avaliou-se a densidade básica da madeira e casca de sete espécies (E. saligna, E. grandis, E. urophylla, E. camaldulensis, E. citriodora, E. paniculata e E. pellita) e três clones de eucalipto (híbridos de E. grandis x E. urophylla) antes e durante o cultivo das linhagens LE-95/01 e LE-96/18 de shiitake (Lentinula edodes) em toras. Cada linhagem de shiitake foi inoculada em nove toras de cada tipo de eucalipto com 1 m de comprimento e 9 a 14 cm de diâmetro. Assim, o delineamento experimental foi inteiramente casualizado, com 20 tratamentos e 9 repetições, sendo cada repetição correspondente a uma tora. As toras foram mantidas em estufa climatizada, com temperatura de 25 ± 5ºC e umidade relativa do ar entre 60-80% durante 12 meses. Para a determinação da densidade básica, analisaram-se cunhas de discos e cascas de eucalipto recém-cortadas (sem inoculação das linhagens de L. edodes) e em cunhas de discos retirados de toras já inoculadas com as linhagens de L. edodes após 8 e 12 meses de incubação. Verificou-se que a densidade básica da madeira, ao longo do ciclo de cultivo, foi reduzida em todos os tipos de eucalipto.
