A segunda metade do século XIX mostra-se como um período no qual em cada um dos grandes poetas se abre e se fecha o leque de correspondências da analogia: Baudelaire, Verlaine, Rimbaud, Mallarmé, expressam em sua obra essa tendência à busca da verdadeira vida, do real oculto, movimento em que as sensações desempenham um papel primordial. Atualmente, a obra de Le Clézio vem confi rmar a procura de um mundo completo suscitado pela poesia, o único modo possível de se traduzir em palavras o êxtase sensorial: é o que mostram tanto seus ensaios, quanto suas obras fi ccionais, de L’extase matérielle e L’Inconnu sur la terre a Mondo et autres histoires, Désert, La Quarantaine e Coeur brûle et autres romances, corpus selecionado para a discussão do assunto.

Fruit processing for beverage production purposes is a way of adding value to the raw material and of raising the farmer s income by increasing the demand. Thus the objective of this work was the production of fermented West Indian cherry beverages and their physicochemical and sensory evaluation. The beverages were produced based on the Brazilian legislation for fermented fruit beverages and wine. The fermented beverages were produced from West Indian cherry pulp (pulper) and juice (press) and sweetened with sugar to obtain three types of beverage: dry, semidry and sweet. The beverages were submitted to the following physicochemical analyses: pH, alcohol, reducing sugars, total reducing sugars, total acidity, volatile acidity, fixed acidity, dry extract, reduced dry extract, alcohol to reduced dry extract ratio, free sulphur dioxide, total sulphur dioxide and turbidity. In the sensory analysis, the beverages were assessed using a 9-point hedonic scale, evaluating the attributes of appearance, odour, flavour and overall assessment. The chemical and sensory results were submitted to an analysis of variance and the means compared using Tukey s test (5%). Both the raw materials (pulp and juice) and the different sugar concentrations (dry, semidry and sweet) interfered in the sensory and physicochemical parameters of the fermented West Indian cherry beverages, the tasters showing preference for the sweetened beverages.

This research had as objective to evaluate the effect of extrusion temperature and screw speed on physical and rheological properties, as well as, the sensory acceptance of cassava and passion fruit snacks produced in single-screw extruder. A central composite design with 11 treatments was used, considering as dependent variables: expansion index (EI), specific volume (SV), water solubility index (WSI), water absorption index (WAI), color (L*, a*, b*) and pasting properties (RVA). The products were flavored and analyzed for global acceptance. The results showed significant effects of temperature and screw speed on the dependent variables. The chocolate flavored snacks obtained good acceptance.

Years after the constructivism theory was adopted by “Parameters for National Syllabuses”, the results have pointed to a worse performance in teaching and learning with regards to reading and writing. This article presents the conclusions proceeding from investigation about the probable reasons for the student’s lack of success in reading and writing, and its relation to Emília Ferreiro’s constructivism proposals. Interviews were made as well as sit in class observation were done, with twenty teachers at six Fundamental Level 1 schools in Ourinhos, SP State, in schools that had been awarded the best and the worst performance rating in the Prova Brasil-2005, with this objective: to know and analyze the teacher’s conceptions under their practices and their practices in the classes. The conclusion is: it is not possible to attribute the students’ lack of success in reading and writing; these studies showed that many teachers, most of them, have a non-constructivist concept of teaching and learning, it means that they do not apply Ferreiro’s researches.

Tactile sensibility allows for adequate neuropsychomotor development. In addition, it enables the understanding of the subject’s own body, actions and explorations of objects, people and the environment. Previous studies have evaluated 3 to 10 year-old children. Herein, we evaluate the tactile sensibility in adolescents. The aim of this study was to verify whether the rapid growth of the body changes the normal pattern of tactile sensibility in adolescents. Furthermore, we provide evaluation material that is easy to use, simple, and secure to handle, designed to attend the specific age range studied. Thirty-two young participants between 11 and 18 years old, sixteen males and sixteen females, were evaluated. The adolescents go to public school and present normal development patterns. Graphesthesia, stereognosia, and Semmes-Weinstein monofilament tests were performed to evaluate the sensibility on the ventral and dorsal sides of the right and left hands. A questionnaire was used to identify the relevant activities performed with the hands during the studied period. The adolescents tested were collaborative during the research and presented curiosity regarding the boxes used in the experiment. Results indicated alterations in the tactile sensibility on the dorsal side of the hands from 13-year- old males. The major activities indicated by the adolescents were writing and sports for males and writing and cleaning for females. First evidences of possible changes in the normal tactile sensibility during adolescence were observed in this study.

OBJETIVO: O objetivo deste estudo foi comparar o comportamento oscilatório de cada membro inferior na tarefa de alcance frontal. Além disso, verificar a influência da informação visual nestas tarefas, em pacientes com doença de Parkinson. MÉTODO: Participaram deste estudo 8 pacientes com doença de Parkinson idiopática, de ambos os sexos, classificados entre os estágios 1 a 3 da escala de Hoehn e Yahr e 8 sujeitos controle. Para avaliar o comportamento oscilatório, foi aplicada a tarefa de alcance frontal que consistiu em elevar os braços a 90º, posicionar uma mão sobre a outra, estender os dedos e tentar alcançar à frente o mais longe possível sem retirar ou mover os pés da posição inicial. Os pés foram posicionados sobre duas plataformas de força, próximas uma da outra. Para aquisição dos dados de comportamento oscilatório foi utilizado o software AMTI Net Force, com freqüência de coleta de 100 Hz. Foram realizadas 3 tentativas para cada condição (com e sem informação visual), totalizando 6 tentativas com duração de 30 segundos cada. As avaliações clínica e postural foram realizadas no estado on do medicamento. Variáveis do COP analisadas: Trajetória, Velocidades Ântero-posterior e Médio-lateral e Limite de Estabilidade. RESULTADOS: Plataforma 1- MANOVA revelou apenas efeito de momento, Wilk’s Lambda= 0,04, F(8,6)=18,74, p≤0,01. Testes univariados apontaram diferença significativa para as variáveis Trajetória (F=31,62, p<0,001), Velocidade média médio-lateral (F=83,24, p<0,001) e para Limite de estabilidade (F=27,36, p<0,001). Plataforma 2- MANOVA revelou apenas efeito de momento, Wilk’s Lambda=0,026, F(8,6)=28,23, p<0,01. Análises univariadas apontaram diferenças no Momento para trajetória F(2,26)=104,07, p<0,01, velocidade média ântero-posterior...(Resumo completo, clicar acesso eletrônico abaixo)
