In this work, the continuous extraction of solute from vegetable matrix has been studied. An industrial apparatus was used to acquire information for process implementation. To this end, a batch study was conducted to obtain the extraction kinetics, and the behavior of the matter under pressure and raw plant transport were investigated. Coupling these elements allows the representation of the extraction yields according to time in the apparatus. A methodology for the change from batch to continuous extractor based on laboratory tests is proposed.

In this paper a social constructionist approach is used to frame an analysis of the effects of physical impairment on selfperception. The results are reported of a recent study in which questionnaires were mailed to 314 people who were paraplegic and 284 who were post-polio, as well as to a control group of 327 who had no visible physical impairments.While the people who were paraplegic and those who made up the control group gave similar answers to most of the survey questions, those who were post-polio displayed a consistent, but different, way of reporting on their self-representations. Moreover, this discourse, which included such self-described characteristics as self-control, a sense of duty, and a concem for meticulousness, was consistent in the post-polio group across sex and age.It is concluded that the date of onset of physical impairment is significant in infiuencing the self-representation of persons with physical impairments. The socio-historical evolution of social practices and cultural expectations and norms with respect to persons with disabilities in Westem cultures were taken into account in interpreting the results of this survey.
