(Universidade Federal de São Carlos, 2018-09-26) Gomes, Daniel Telhado; Pandolfelli, Victor Carlos; https://lattes.cnpq.br/7369376873984839; https://lattes.cnpq.br/5134702097016780
The increasing demand for petroleum experienced in the last decades has pushed the barrel price to a level never seen before, stimulating a race for rising production volumes and taking us to even deeper waters. On a similar move, the refining industry has adapted itself and optimized its processes, resulting in higher unit operational availability. During this period, one of the initiatives explored to reduce maintenance downtime was the increment of phosphate-bonded refractories installation, replacing the cement based castables. In addition of satisfactory thermo-mechanical properties up to 1,500 °C, these products allow high heating rates after curing without explosion risk and chemical adhesion on pre-fired refractory linings, speeding up equipment’s repair. Despite the advantages, the shortage production of these materials in Brazil required its importation, turning costs 5–15 times higher than those for conventional castables. Prospecting potential new suppliers, this work characterized imported and previously qualified phosphate-bonded products, comparing them with those newly developed by national manufacturers, aiming to evaluate the performance and suitability for using these formulations. The results showed that in many aspects the national materials overcame the previously qualified references, being viable options for using in oil refineries. On the other hand, it was also observed the need of improvement and adjustments, motivating the development of a second generation of phosphate-bonded castable refractories in Brazil. Based on the obtained results, requirements were also proposed for materials specification.
Aconselhamento em planejamento reprodutivo de mulheres em condições de vulnerabilidade, segundo a percepção dos profissionais da estratégia saúde da família
(Universidade Federal de São Carlos, 2018-09-26) Lujan, Luciana Francisco; Callegari, Fernanda Vieira Rodovalho; https://lattes.cnpq.br/6123189460389930; Carbol, Maristela; https://lattes.cnpq.br/9852217198710064; https://lattes.cnpq.br/1821090443006044
The reprodutive planning is a thematic widely discussed in the health political programs of Brazil. For substantiate itself in prevention actions, promotion, information and health education, pertains respect especially to basic attention. Recognizing to special protection women in greater vulnerability situation, includes in the health professionals actions, the counseling as a caution integrated space. As a social assistent from the Support Core to Family Health (NASF) and integral member of the technical sterilization from São Carlos/SP Municipal Secretary of Health, I could watch the actions of health professionals from AB (basic attention) envolved in the reprodutive planning. This research was delineated from this experiences with the goal of analyzing the reprodutive planning counseling of women in vulnerability conditions in the Families Health Unities (USF), according to the doctors and nurses perception. Treat a descriptive exploratory study of qualitative approach. The integrants were doctors and nurses from São Carlos/SP USP. The data collect ocurred on the first period of march until june 2017, by means of semi-structured open interview. From the collected material, of accomplished deductions and theoretical referential perspective, accomplished the analysis by thematic categories. From the 26 participants, checked that 42% hat between 38 and 47 years old, being the most of female sex and with performance in USF above of five years. With the interviewed stories it was possible to verify that exists a singular and complex relationship in the reprodutive planning counseling of women in vulnerability conditions, evidencing two analytical categories: triggering factors of vulnerability and reprodutive planning counseling and the vulnerability particularities. The interviewed by recognizing factors that produces vulnerability and that influences the health-sickness process, pointed being indispensable an extended look in reprodutive planning counseling of this women to produce a more effective health care. Through the organization process of work is possible to consolidate the reprodutive planning counseling as a production space of new practices and development of new technologies at woman health area. Conclued that the doctors and nurses from Family Health Strategy (ESF) identified women in vulnerability conditions that experience uneven way and in disadvantage in socioeconomic, cultural historic and political factors. To perform the reprodutive planning, the professionals have used management devices and arrangements of care and extended clinic.
