An artificial taste sensor based on conducting polymers.

Pure and composite nanostructured films of conducting polymers were used as individual sensing units constituting an electronic tongue. The use of extremely thin films for signal transduction via impedance spectroscopy measurements in the frequency range 10-1 MHz allows the detection of trace amounts of tastants and inorganic contaminants in liquid systems. In addition, the sensor could detect the suppression of sourness by sweetness displaying similarities with the biological system. Brands of several commercial beverages could be easily distinguished without complex analysis, including the discrimination of waters, tastants and wines.

[Family planning: an evaluation of the program at a health center (1986-1990)].

OBJECTIVE: To gain dome idea of the characteristics of the population attended at a Family Planning Clinic (FPC) in a Health Centre, attempting to find the coverage and performance of the Clinic. DESIGN: Retrospective descriptive study, which analysed 403 cases between July 1986 and December 1990. SITE. Family Planning Clinic in the "Huerta de la Reina" Health Centre. PATIENTS AND OTHERS PARTICIPANTS: Women of child-bearing age who requested a consultation during the period of the study. MAIN MEASUREMENTS AND RESULTS: A uni/bivariate analysis of the studies was carried out. Coverage of 16.3% of the population of child-bearing age, with 69.5% of the women being under 29, was attained. The most frequent motive for a consultation was advice on methods of contraception. Oral contraception (65.0%) was the most common form prescribed. 27.1% of those attending consultation were referred to the second level. Attendance at periodic check-ups was very low.
