Spray drying of the buriti pulp at different maltodextrin concentrations and temperature

In this work, the formulations prepared with buriti pulp and different maltodextrin concentrations (5, 10 and 15%) were dried in spray dryer and the chemical, physical and physical-chemical characteristics of the formulations and powder samples were evaluated. In this drying process two kinds of powder samples were collected: one into drying chamber and another in the cyclone. Using a factorial experimental planning, the experiments were conducted, in order to assess the moisture and ash contents, total acidity and density of both samples. The formulations dried in the spray dryer presented be feasible for the production of buriti pulp powder; however, powder samples collected into drying chamber and cyclone were different. Among the parameters analysed, it was found that only for density the samples collected into drying chamber, that the first-order empirical model obtained was statistically significant and predictive

Loss analysis in the process of profiling a medium-sized metallurgical company

In order to become competitive and stand out from the competition, companies seek for a differential in their market action, eliminating or reducing their losses in the productive process. The Lean Manufacturing system and its tools help the company in the quality of its production, allowing to analyze, identify and classify the types of waste and, consequently, to propose continuous improvements eliminating activities that do not add value. The present study is an analysis of losses in the sheet metal profiling process for the manufacture of trapezoidal tile in the ‘Dimensão Aço Longos e Planos’ industry, a medium-sized metallurgical company that mainly serves the civil construction sector whose objective is to identify the Loss of production to generate proposals for improvements to reduce and eliminate waste. The method used to elaborate this work was on the survey of processing data to identify and classify the wastes in the production of tiles. It was observed that the company presented the seven process losses, the most significant being the setup generated by the profiling machine, causing waits and excessive inventory

Application of FMEA as support in the preventive maintenance of the pneumatic machine norbar

This paper aims to identify the use of the Failure Mode and Effect Analysis (FMEA) tool as a support for the preventive maintenance of the Pneutorque Norbar machine, as well as in the strategic maintenance planning applied. A bibliographic study was carried out to contextualize the subject, followed by a case study. The research demonstrates how the development of an equipment failure analysis process, identifying the results obtained through the FMEA tool with the Statistical Process Control (CEP). For this, we analyzed this method in the process of maintenance and support of the Pneutorque Norbar machine, intending to obtain satisfactory results in the improvement of the maintenance planning process

Leading the Pathway : How Unicamp Is Implementing Sustainable Practices in the Energy Sector in Its Campuses?

Universities are powerful drivers to create and advance knowledge on sustainable development. Furthermore, they can be used as a controlled environment to apply innovative technologies and approaches. This process also embraces industry and government, in the triple helix innovation model, as in the University of Campinas (Unicamp), Brazil—one of the best Latin American universities (3rd)—and immersed in a significant financial and technological region in Brazil. It has 6 Campuses in 3 different cities, almost 40,000 students (high school, technical education, undergraduate, graduate, residency, and extension courses), and almost 10,000 employees (professors, technicians, and others). Due to its relevance and excellence, Unicamp decides to lead the pathway in urban sustainable development through its Sustainable Campus Project launched out in 2017 in partnership with an energy company (CPFL Energia) and with the Brazilian Electricity Regulatory Agency (ANEEL) through a Research and Development program. This chapter presents the Sustainable Campus Project’s main goals, practices, and current results, such as implementing electric buses, local solar generation, electrical efficiency improvement, and education. Through this case, we aim to show how universities, especially in developing countries, can lead the local pathway to a sustainable world

The surgical safety checklist and patient outcomes after surgery: a prospective observational cohort study, systematic review and meta-analysis

© 2017 British Journal of Anaesthesia Background: The surgical safety checklist is widely used to improve the quality of perioperative care. However, clinicians continue to debate the clinical effectiveness of this tool. Methods: Prospective analysis of data from the International Surgical Outcomes Study (ISOS), an international observational study of elective in-patient surgery, accompanied by a systematic review and meta-analysis of published literature. The exposure was surgical safety checklist use. The primary outcome was in-hospital mortality and the secondary outcome was postoperative complications. In the ISOS cohort, a multivariable multi-level generalized linear model was used to test associations. To further contextualise these findings, we included the results from the ISOS cohort in a meta-analysis. Results are reported as odds ratios (OR) with 95% confidence intervals. Results: We included 44 814 patients from 497 hospitals in 27 countries in the ISOS analysis. There were 40 245 (89.8%) patients exposed to the checklist, whilst 7508 (16.8%) sustained ≥1 postoperative complications and 207 (0.5%) died before hospital discharge. Checklist exposure was associated with reduced mortality [odds ratio (OR) 0.49 (0.32–0.77); P\u3c0.01], but no difference in complication rates [OR 1.02 (0.88–1.19); P=0.75]. In a systematic review, we screened 3732 records and identified 11 eligible studies of 453 292 patients including the ISOS cohort. Checklist exposure was associated with both reduced postoperative mortality [OR 0.75 (0.62–0.92); P\u3c0.01; I2=87%] and reduced complication rates [OR 0.73 (0.61–0.88); P\u3c0.01; I2=89%). Conclusions: Patients exposed to a surgical safety checklist experience better postoperative outcomes, but this could simply reflect wider quality of care in hospitals where checklist use is routine

Critical care admission following elective surgery was not associated with survival benefit: prospective analysis of data from 27 countries

This was an investigator initiated study funded by Nestle Health Sciences through an unrestricted research grant, and by a National Institute for Health Research (UK) Professorship held by RP. The study was sponsored by Queen Mary University of London
