Aplicação da modelagem no estudo da teoria cinética dos gases

In this term paper is studied the use of models and analogies and it's influences in the study of chemistry, for learning and understanding of concepts related to the kinetic theory of gases. It was developed an activity with students of high school second year, enrolled in a State school, in the city of Bauru-SP. It was built and developed a model using the mechanical vertical model scheme, based on the proposal of Professor Luiz Ferraz Netto, for the teaching of the kinetic theory of gases. It was applied a questionary to evaluate the effect of the model in the classroom, and the analysis of data was done in descriptive qualitative way. It was verified that the methodology favored the development of conceptual understanding, demonstrating significant results on the theme of learning

Dispositivo de microdescargas em gases na pressão atmosférica

This work describes the development of an electro-mechanical micro-discharges device operating at ambient condition of pressure and temperature, capable to produce plasma jets for surface finishing. The discharges are produced through a needle shape electrode hollow cathode type by which flows the helium gas. The voltage applied on the electrode is provided for an AC/AC switching voltage converter of full-bridge topology. The converter is energized by a power line of 110/220 VAC, 60 Hz and gives a 1000 V peak-to-peak from 5 kHz to 40 kHz square waveform output. The output frequency is defined by a control signal provided by an external signal generator. The equipment setup includes output acquisition of voltage and current and a photo-detector for photo-electrical measurements, which allows an optical characterization of the plasma jet

Morbidity following sural nerve harvesting: A prospective study

Objective: To evaluate donor site morbidity following sural nerve harvesting, with special attention to the recovery of sensory loss. Methods: We prospectively followed 38 subjects who underwent sural nerve harvest, including two with bilateral nerve excision. Symptoms related to sural nerve excision were evaluated and demarcation of the area with reduced touch sensation was quantified. Assessments were performed periodically up to 1 year after surgery and the results of different sensory evaluations were compared. Results: A significant reduction of sensory deficit was identified between consecutive evaluations (p < 0.05). Decreases of 26.85%, 20.69% and 24.29% were observed 3, 6 and 12 months after surgery, respectively. Shock-like pain (7.5%), stabbing pain (7.5%), and numbness (5%) were the most frequently reported symptoms. All symptoms were brief and resolved spontaneously 3-6 months after surgery. Conclusion: Sural nerve harvest can be performed with acceptable morbidity. When present, symptoms resolve between the third and sixth month after surgery and a significant reduction of sensory loss in the area innervated by the sural nerve was observed during the first year of follow-up.
