Researchers in the field of Augmentative and Alternative Communication point out the lack of instruments for assessing children and young people with a complex communication needs. This study's focus is the selection of words for creating an instrument for the vocabulary range in non-speaking children aged two to eleven years and eleven months. Three studies were performed. The first study identified and described tools available for assessing receptive vocabulary and their respective word lists. The second identified and described research that presented word inventories or word lists. The third study identified the vocabulary reported by parents and teachers. The words that were identified in the three studies were analyzed according to: the number of times they occurred; the Picture Communication Symbols system classification; and a semantic and syntactic classification. Based on these studies the following criteria for vocabulary selection were established for word selection: the 45 words which appeared in all three studies, the words that occurred five times or more, considering the three studies, representing 167 (14.14%) words; the words identified in study one or two, but that had been reported by the families - 183 (19.37% out of 945 words) - or by teachers - 108 (11.43% out of 945 words). The word list was composed of 269 items, classified in 18 semantic and syntactic topics; it represents an initial tool for professionals in the field of health and education to set goals for beginning assessment of children and teenagers who are users of Augmentative and Alternative Communication systems.

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

The objective of this paper is to introduce a model, called the Model of the System of Schemes of Actions and Operations on Symbols and Signs (MoSSAOSS), that articulates a systemic, systematic, and synthetic view of some of the principal theoretic and experimental results obtained by Piaget and his coworkers. Here, the term model means a schematic representation of experience, the relation of whose elements can be explored by means of logic and mathematics in order to deduce properties that correspond, in a sufficiently accurate form, to direct observable empirical properties. The MoSSAOSS model is intended to reveal in an abstract and simplified form, and through explicit hypothesis and definitions, the general structure and function of the System of Schemes of Actions and Operations on Symbols and Signs. It is this system that furnishes the elements that make possible the diverse structures necessary for the knowledge of the epistemic subject, the subject of knowledge, the stages in their construction, and the attribution of significations to objects, to situations, and to the actions and operations of the subject itself.

Este artigo é composto de duas seções: a primeira consiste de um exame empírico das manifestações de junho baseado no debate público e, a segunda, numa sintética formulação teórica sobre o enquadramento interpretativo para, em seguida, apresentar o que se considera os dois quadros interpretativos predominantes durante aquele ciclo de manifestações.

This study was developed to evaluate the performance of different coagulant and pH dosages by applying the use of Dissolved Air Flotation (FAD) to enable its use in effluent treatment of the extraction process of palm oil. The study was developed in the laboratory, where studies about emulsions stability were made for the production of a synthetic effluent which best suit the characteristics of raw effluent. The synthetic water that would be used in the tests of FAD was produced, once the stability and characterization which best approached the raw wastewater was obtained. Trials tested three coagulant doses, combined with various pH ranges and five upward velocities (Va), finding an optimal range of this combination. Some operating parameters such as time and gradient of rapid mixing (20 s / 1000 s-1), time and gradient flotation (15 min / 60 s-1), chamber pressure saturation (450 kPa) and recirculation rate (20%) were set. In this way, samples were collected for analysis of the removal of turbidity parameters, suspended solids and oils and greases. This one is obtained by a correlation turbidity x oils and greases, referring to the previous analysis. The degree of removal obtained were 73,97% for turbidity, 51,4% for total suspended solids and 86,2% for oils and greases. Removal rates may be increased in later studies, by ranging the velocity gradient and flocculation parameters and the recirculation ratio, and by using lower flotation speeds to these effluent characteristics.
