Filtros de areia aplicados �� irriga����o localizada: teoria e pr��tica

The application of sand filters in localized irrigation systems is recommended in the presence of organic and algae contamination. The proper design and maintenance of these equipments are essential to assure an effective water quality control, in order to reduce the emitters clogging, to keep its water application uniformity, and to prevent increasing in the system operation costs. Despite the existence of some references about design, operation and maintenance of these filters, they are dispersed, with not enough details to guarantee the optimization of its hydraulics structure design and the proper selection of porous media to be used. Therefore, the objective of this work was to report a current literature review, relating practical information with scientific knowledge. The content of this review would help to induce and intensify the research on this subject and to contribute so the operational functions for the equipment are reached. It is also expected to assist the improvement of the filtration and flushing processes in the agricultural irrigation and the development of original design procedures and the rational use of these devices.

M��es ouvintes com filhos surdos: concep����o de surdez e escolha da modalidade de linguagem

The aim of this study was to analyze the conceptions that hearing mothers of deaf children have about deafness and relate it to the language mode used by the mother and the child. We interviewed 10 mothers of deaf children, five of whom were prescholars and five of school age. The content was analyzed as to thematic and category types, with emphasis on the categories conception of deafness and choice of language mode . Data analysis showed that one mother seems to see deafness as a disease, another as a difference and the other mothers were found to be somewhere between these two views. In relation to the preferred language mode, half the mothers reported that their children predominantly use signs, the other half uses speech and signs, with the exception of one child who uses only speech. The child whose mother acts as if deafness is a disease uses speech while another one whose mother acts as if deafness is a difference uses speech as well as signs.

Resultados da cirurgia de reservat��rios ileais em pacientes com doen��a de Crohn

BACKGROUND: Total rectocolectomy and ileal pouch-anal anastomosis is the choice surgical procedure for patients with ulcerative colitis. In cases of Crohn's disease post-operative diagnosis, it can be followed by pouch failure. AIM: To evaluate ileal pouch-anal anastomosis long-term outcome in patients with Crohn's disease. METHODS: Between February 1983 and March 2007, 151 patients were submitted to ileal pouch-anal anastomosis by Campinas State University Colorectal Unit, Campinas, SP, Brazil, 76 had pre-operative ulcerative colitis diagnosis and 11 had post-operative Crohn's disease diagnosis. Crohn's disease diagnosis was made by histopathological biopsies in nine cases, being one in surgical specimen, two cases in rectal stump, small bowel in two cases, ileal pouch in three and in perianal abscess in one of them. The median age was 30.6 years and eight (72.7%) were female. RESULTS: All patients had previous ulcerative colitis diagnosis and in five cases emergency colectomy was done by toxic megacolon. The mean time until of Crohn's disease diagnosis was 30.6 (6-80) months after ileal pouch-anal anastomosis. Ileostomy closure was possible in 10 cases except in one that had ileal pouch fistula, perianal disease and small bowel involvement. In the long-term follow-up, three patients had perineal fistulas and one had also a pouch-vaginal fistula. All of them were submitted to a new ileostomy and one had the pouch excised. Another patient presented pouch-vaginal fistula which was successfully treated by mucosal flap. Three patients had small bowel involvement and three others, pouch involvement. All improved with medical treatment. Presently, the mean follow-up is 76.5 months and all patients are in clinical remission, and four have fecal diversion. The remaining patients have good functional results with 6-10 bowel movements/day. CONCLUSION: Crohn's disease diagnosis after ileal pouch-anal anastomosis for ulcerative colitis may be usual and later complications such fistulas and stenosis are common. However, when left in situ ileal pouch is associated with good function.

TEORIA SINT��TICA: DE UMA PERSPECTIVA DE -ISMOS PARA UMAPERSPECTIVA DE PROGRAMAS

This paper tries to show that the developments in linguistic sciences are better viewed as stages in a single research program, rather than different ideological -isms. The first part contains an overview of the structuralistas' beliefs about the universality and equivalence of human languages, and their search for syntactic universals. In the second part, we will see that the generative program, in its turn, tries to answer why language is a universal faculty in the human species and addresses questions about its form, its development and its use. In the second part, we will see that the paper gives a brief glimpse of the tentative answers the program has been giving to each of these issues.

A teoria e a pr��tica: a quest��o da diferen��ano discurso sobre e da sala de aula

The main purpose of this paper is to question the relationship between theory and practice or basic and applied research in the domain of Applied Linguistics and classroom discourse. In order to achieve our aim, some theoretical texts, some recorded and transcribed classes as well as some teachers and students opinions about reading and writing were analysed. Results have shown that 1) practice is not the direct application of theoretical data: the relationship between them is not as simple as some applied linguists seem to believe because of the action of the unconscious in the constitution of subjectivity; 2) the conceptualization of the theoretical issues takes place in a confused and disorderly manner mixed up with personal experiences and previous knowledge (practice). We intend to question the fact that practice comes as secondary to theory.

Uma observa����o sobre o lugar da teoria da liga����o e do crit��rio tem��tico dentro do programa minimalista

In this paper I present some evidencie that forces us to conclude that within the Minimalist Program (Chomsky 1993; 1995), Binding Theory (BT) should be computed after LF (Logical Form). I show that derivations leading to structures containing violations of BT-Principles must converge at LF, since less economical alternative derivations respecting those principles are also ungrammatical. Being irrelevant to the notion of convergence, BT must apply after LF. A similar reasoning reveals that the Theta-Criterion should have the status of a bare output condition appling at LF, since less economical derivations are allowed by the computational system to prevent violations of it.
