A computerized tool to assess reading skills of students with motor impairment.

Conventional tests for assessing the early reading skills of preschool children on school entry are not accessible to students with motor limitations of upper limbs. This paper presents a game-like computerized test featuring an appealing scenario that is accessible to these students. It was developed on a platform that creates 2D vector graphics and contains three phases of interactive content accessible through an adapted peripheral.

Enhanced Sensitivity of Gas Sensor Based on Poly(3-hexylthiophene) Thin-Film Transistors for Disease Diagnosis and Environment Monitoring.

Electronic devices based on organic thin-film transistors (OTFT) have the potential to supply the demand for portable and low-cost gadgets, mainly as sensors for in situ disease diagnosis and environment monitoring. For that reason, poly(3-hexylthiophene) (P3HT) as the active layer in the widely-used bottom-gate/bottom-contact OTFT structure was deposited over highly-doped silicon substrates covered with thermally-grown oxide to detect vapor-phase compounds. A ten-fold organochloride and ammonia sensitivity compared to bare sensors corroborated the application of this semiconducting polymer in sensors.
