title: Dynamic risk calculation model applied to gas compressor

description: Abstract The present article proposes to apply a Risk-Based Maintenance methodology in a gas compression system. This risk calculation is based on a semi-quantitative mathematical model that uses the interdependence of process variables and predictive maintenance data applied in a Condition-Based Maintenance methodology, in order to obtain the calculation of the dynamic risk. This promotes a review of maintenance and reliability strategies proactively in real time. The dynamic risk applied to the system involves the interface of predictive maintenance and process variables with the reliability and risk analyses of the system. This value, which is associated with the financial aspects, safety, people and environment, can be compared to the tolerable risk of production plant operation, providing operation or maintenance decisions. An example demonstrates the integration of process and maintenance data using this model methodology for a gas compression system. This framework can be applied to evaluate the integrity of systems, providing critical risk-based information for the maintenance and operation teams, assisting then in the mitigation of failures in the production systems.

title: Urban influence on the water quality of the Uberaba River basin: an ecotoxicological assessment

description: Abstract Ecotoxicological tests applied to Tradescantia pallida, Allium cepa and Lactuca sativa were used to assess the quality of the Uberaba River basin under urban area influence. Water samples were collected at eight different points during the dry season. The samples were assessed using the following toxicity indicators: micronuclei percentage in T. pallida pollen grains (TRAD-MN), seed germination, root growth, mitotic index (MI) and micronuclei in A. cepa root-cells, and seed germination and root growth in L. sativa. Water physicochemical parameters such as temperature, dissolved oxygen (DO), pH and electric conductivity were assessed in situ. The three plant species were efficient bio-indicators, since they presented good cost-benefit and fast and easily interpreted results, thus completing the physicochemical parameters. There was strong correlation between seed germination and root growth among the ecotoxicological parameters assessed in L. sativa and A. cepa. The micronuclei percentage in T. pallida and the MI in A. cepa presented strong correlation with water electric conductivity and moderate and negative correlation with DO. Water electric conductivity ranged from 75 to 438 µS.cm-1; and the DO concentrations ranged from 0.5 to 6.9 mg.L-1. The importance of pollution control measures in the Uberaba River basin stands out. From the supply-water capture point, the basin is strongly affected by pollution, mainly in the tributaries that cross the city. It presents a short, or almost absent, riparian forest line, residues on the river banks, and it is impacted by discharges of untreated sewage, among other anthropic actions.

title: Perception of medical students about the termination of life

description: Abstract The advancement of medicine has improved the treatment of diseases, modifying the population’s morbidity and mortality pattern, with an increase in chronic diseases. This phenomenon made it urgent to properly interpret the termination of life. Considering this need, this cross–sectional, descriptive and analytical study analyzed data regarding the perceptions of 111 students from the sixth year of the medical school about end-of-life palliative care. Data were collected between August and November 2016 through a questionnaire and analyzed by statistical tests using the Iramuteq software. 37.3% of students reported difficulty communicating a patient’s death to their family; 60% of them felt unprepared or had doubts regarding how to deal with death in the emergency department; 25% of students reported not knowing the term Euthanasia; 53%, Orthothanasia; and, 56%, Dysthanasia. Results show that there are still gaps in the knowledge of medical students making evident the need for medical schools to reinforce educational practices regarding death.

title: Analysis of saliva by Fourier transform infrared spectroscopy for diagnosis of physiological stress in athletes

description: Introduction Saliva is the most promising biofluid to monitor the physiological state of athletes, because this method is not invasive and has low contamination risks. The characterization of saliva by Fourier transform infrared spectroscopy (FT-IR) has been studied as an alternative technique to the standard clinical analysis. However, methodological procedures for saliva analysis are not completely clear, especially in terms of influence of storage conditions and sample preparations for infrared analysis. Thawed saliva includes a precipitate, which may influence the infrared spectral analysis. Thus, the purpose of this study was to show the spectral differences of the precipitate, supernatant, and a combo, as well as the best way to classify the physiological state of the athletes by FT-IR. Methods The saliva collection was performed before, immediately after, and two hours after a handball match. After the storage of samples at –20 ○C, it was possible to identify two phases (precipitate and supernatant) and to determine the biochemical differences between the spectra of each phase, which were distinctly analyzed by the second derivative and deconvolution bands. Results The precipitate and supernatant results showed characteristic bands, especially in the protein regions. All FT-IR spectra were also statistically classified by linear discriminant analysis (LDA), using principal component analysis (PCA). The LDA precipitate and supernatant had lower value when compared to combo spectra (Combination of precipitate and supernatant) with 82%, showing that this combination is the best way to discriminate spectra of saliva samples collected before, immediately after, and 2 h after physical effort. Discussion The results showed that it is possible to differentiate biochemically the two salivary phases, as well as the importance of the homogenization process of saliva samples to classify the physiological status of athletes using FT-IR.

title: Spatial and seasonal variation of zooplankton in reservoirs of the Cantareira system, Brazil

description: Abstract This study examined the spatial and seasonal variation of zooplanktonic communities and their relationship to the physical, chemical and biological properties of water in five reservoirs (Jaguari, Jacareí, Cachoeira, Atibainha e Paiva Castro) of the Cantareira system. Sampling was performed in May/June and November/December 2013 at 19 sites. To verify similarity of zooplankton attributes, we applied a two-way similarity analysis and a non-metric multidimensional scaling. Relationship between biological and environmental descriptors was examined by Pearson correlation. A total of 35 taxa was identified. Rotifers were predominant in terms of species richness and juvenile copepods followed by Bosmina freyi were the most abundant. Overall, the sites showed mesotrophic conditions, with the exception of the Jaguari reservoir, which was considered eutrophic. Based on the analysis, spatial and seasonal variations and correspondence between environmental indicators and densities were observed. Reservoir morphometry, water retention time, ecological interactions and water quality might explain the observed trend.

title: Latter of Drafting by Pesticide Contamination Risk on the Estiva Stream Watershed, Brazil

description: ABSTRACT The aims of this work was to determine risk areas with pesticide contamination on the Estiva stream watershed, a tributary of Uruçuí-Preto river, Brazil. Environmental data was used to determine layers of water way, infiltration and runoff with the transport of pesticide. The overlay of this information has generated a map with the risk areas with pesticide contamination. The basin had high human disturbance, with an increase of about 55% of land use and occupation by agricultural crops, in a period of approximately 27 years (1984-2011). An area of 269 Km2, correspondent to 11% of the basin area, has a high potential pesticide contamination risk, 45% medium contamination risk and 44% have little contamination risk.
