title: Nursing educational intervention for the identification of Adverse Events in hemodialysis

description: ABSTRACT Objective: To develop an educational program aimed at the qualification of the nursing technicians that makes possible the understanding of Adverse Events (AE), aiming to adapt the data records; to elaborate tools for the records of the AE in hemodialysis patients; and to assess the knowledge before and after the educational program. Method: An educational intervention was conducted through a classroom and online course on how to recognize and record AE in hemodialysis. The effectiveness of the program was assessed through the gain of knowledge measured through online record of the AE in fictitious problem cases before and after the course. Result: Sixteen nursing technicians participated in the study. In the initial test, the mean score was 3.7 ± 0.3 points and in the final assessment was 4.2 ± 0.3 points (p=0.0002). Conclusion: It was possible to verify that the educational intervention contributed to increase the knowledge of the participants and that the training of these can be achieved with classroom and online learning courses.

title: Training in diabetes education: meanings attributed by primary care nurses

description: ABSTRACT Objective: seize meanings attributed by primary care nurses to training in diabetes education. Method: exploratory and descriptive study, with a qualitative approach, with twenty primary care nurses; semistructured interview script, with interviews processed in the IRaMuTeQ software and analyzed through the Descending Hierarchical Classification. The results were subsidized in the Representational Theory of Meaning. Results: nurse training in diabetes education is insufficient for holistic action, although it allows the community to be instrumentalized in specific issues about the disease, using the limited tools available, especially lectures. Nurses find themselves in a context of challenges, improvisations, weaknesses, and limitations that determine the meaning attributed to diabetes education and subsequent actions. Conclusion: the meanings attributed by the nurses revealed an incipient training, which limits the quality of care provided and instigates the search for qualification.

title: Dynamic analysis of gun barrel vibrations due to effect of an unbalanced projectile considering 2-D transverse displacements of barrel tip using a 3-D element technique

description: Abstract In this paper, dynamic analysis of two different weapon systems (35 mm Anti-Aircraft Barrel (AAB) and 120 mm Grooved Tank Barrel (GTB)) under the effect of statically unbalanced projectile has been performed with a new 12 DOF 3-D element technique using Finite Element Method (FEM). The muzzle deviations, which negatively affect the barrel shooting accuracy at firing, are calculated in a time dependent manner using Newmark β algorithm with high accuracy at both axes (y and z) considering the Coriolis centripedal and centrifugal forces. The effect of such fundamental physical parameters as shift from rotating center and angular velocity belonging to the unbalanced projectile on barrel dynamics are analyzed with this new and affective FEM. As a result, it was found out that 1% of a millimeter shift from projectile belonging to a weapon system leads to excessive vibration on both axes and compromises the shooting accuracy of the barrel.

title: Quality of bananas harvested at different development stages and subjected to cold storage

description: ABSTRACT One of the biggest problems faced by banana growers is to determine the most appropriate harvest time. This study aimed to evaluate the post-harvest conservation of 'Prata-Anã' bananas harvested at 16, 17, 18, 19 and 20 weeks after the inflorescence emergence and subjected to 25 days of cold storage at the temperature of 13.5 ºC (± 1 ºC) and 90 % (± 5 %) of relative humidity. The bananas harvested at 19 and 20 weeks after the inflorescence emergence showed a more advanced maturity stage after 25 days of cold storage at 13.5 ºC. The bananas showed an increase in the content of soluble solids, as well as sugars, during the evaluations, after withdrawal from the cold room. Regardless of the fruit age, there was a decrease in the pH values over the 9 days of evaluation, after the 25-day storage period. The fruits at the ages of 19 and 20 weeks presented, on average, starch contents lower than those of the fruits with 16, 17 and 18 weeks. Fruits at the ages of 19 and 20 weeks showed higher extravasation levels on the second day of evaluation. Both the fruit harvest time and storage temperature directly influenced the post-harvest conservation and the physical and chemical characteristics of the 'Prata-Anã' bananas.

title: Dopplerfluxometric and angiogenic analysis of canine mammary tumors

description: ABSTRACT The behavior of the tumor Doppler indexes and gene expression related to neovascularization was evaluated aiming to improve the characterization of neoplastic masses vascularization. Twenty-seven bitches with histopathological diagnosis of mammary neoplasia were submitted to tumor Dopplerfluxometric evaluation and collection of neoplastic fragments to analyze the gene expression of VEGF, FLT-1, FLK-1 and ATR1. Were found 22 epithelial (carcinomas) and five mesenchymal (sarcomas) tumors. Positive correlation was observed between FLT-1 and PS, PI and RI. FLK-1 presented a similar positive correlation with the PS and PI parameters, and a tendency for RI (r= 0.45, P= 0.07), whereas VEGF showed a positive correlation just with PI. VEGF also showed a positive correlation with its receptors, but did not present a correlation with ATR1. FLT-1 and FLK-1 also showed positive correlation with each other, and with ATR1. There was higher mean expression of VEGF in epithelial tumors than in mesenchymal ones. The PS, PI and RI associated with the expression of VEGF and its receptors have been shown to be relevant to characterize neovascularization of malignant tumors, and the differentiated expression of VEGF between the types of mammary tumors, may be an auxiliary indicator in the characterization of malignant breast cancers in bitches.

title: Reduction in the spray drift of 2,4-D in tomato using hydraulic nozzles with air induction and LI-700 adjuvant

description: ABSTRACT The drift of hormonal effect herbicides is a major problem for agriculture, because, even in small amounts, it may cause high losses in crops with plants that are sensitive to their action mechanism. This study aimed to evaluate the efficiency of hydraulic spray nozzles with air induction, as well as the use of the LI-700 adjuvant, in the reduction of the 2,4-D herbicide drift, in tomato crop. A complete randomized split-plot experimental design, with eight replications, was used. Two herbicide solutions were assigned in the plots (with or without the use of adjuvant) [2,4-D (670 g ha-1) and 2,4-D (670 g ha-1) + LI-700 (712.88 g ha-1)], and, in the subplots, five nozzle models [simple fan (JSF11003), simple fan with air induction (AD-IA11003), dual fan with air induction (AD-IA/D11003), simple hammer fan with air induction (TTI11003-VP) and empty cone with air induction (CV-IA10003). The treatments were applied in a wind tunnel, under a pressure of 300 kPa. In a laser analyzer, applying only water, the volumetric median diameter, the relative amplitude and the percentage of drops with diameter lower than 150 µm were measured for all nozzle models. The CV-IA10003 and TTI11003-VP hydraulic nozzles outstand by reducing the 2,4-D herbicide drift and decreasing the damage to tomato plants. The addition of the LI-700 adjuvant to the 2,4-D syrup, independently of the nozzle model, reduces the drift of this herbicide and its effects on the tomato plant root. However, even when adopting these technologies, the application of the 2,4-D herbicide near the tomato crop should be avoided.

title: REVISITING IDEAL GASES AND PROPOSAL OF A SIMPLE EXPERIMENT FOR DETERMINING ATMOSPHERIC PRESSURE IN THE LABORATORY

description: Relevant historical aspects concerning ideal gases were briefly reviewed to provide a condensed resource for the undergraduate student of chemistry. The importance of the barometer and the concept of atmospheric pressure were reviewed and discussed. A combination of Boyle's law with the well-known equation for determining the pressure produced by a column of stationary fluid was used to obtain a graphical method for determining atmospheric pressure under isothermal conditions in the laboratory. Important aspects related to the study of ideal gases were reviewed in light of the pressure-volume data that can be obtained by physical chemistry students using a simple apparatus composed of a commercial hypodermic syringe connected to a mercury manometer. Relevant concepts associated with the measurement of a physical quantity, the importance of linear regression, as well as the use of a graphical method to test the validity of a theory were reviewed from a pedagogical perspective through the experimental study of Boyle's law during regular experimental physical chemistry classes.

title: Water loss management: a constructivist approach

description: ABSTRACT Considering the increasing demand and the water crisis in many countries, loss management in water supply systems seems relevant to all water services. This research set out to build a performance evaluation model to support a sanitation company on the loss management in the water supply systems that it operates, based on the Constructivist Multicriteria Decision Aid Approach (MCDA-C). The model construction followed the three phases of MCDA-C: structuring, actions evaluation and recommendations. The structuring phase resulted in 64 descriptors in four families of fundamental points of view: apparent losses, real losses, operational support, and external relations. At the end of the evaluation phase, the status quo of the water supply system studied was 22.51, within the competitive level judged by the decision-maker. Actions recommendations were designed to improve the status quo performance of those descriptors with compromising performance, judged by the decision-maker as relevant to be improved. Recommendations were important for improving performance in all families of fundamental points of view, resulting in the overall performance of 60.82. This way, the MCDA-C methodology proved to be consistent for the topics covered in this research and confirmed its constructivist assumptions in all the stages developed here: structuring, evaluation and recommendations.

title: Artificial feeding systems for calves in tropical conditions

description: ABSTRACT The objective of this study was to evaluate the bioeconomic performance of calves in the first 60 days of life submitted to three feeding systems. Twenty-four calves (Dutch x Guzerá) were used, 12 males and 12 females, with initial weight of 32.25±4.8kg for females and 36.92±6.8kg for males. The animals were distributed in a completely randomized design, in a factorial scheme (3 x 2). The calves received water at will and six liters of milk replacer a day for 60 days in three different strategies, called the suckling system (SA-30: 3 liters of milk replacer, twice a day until 30 days of age; SA-45: 3 liters of milk replacer, twice a day until 45 days of age; SA-49: 3 liters of milk replacer, twice daily up to 49 days old). The lactation systems studied did not present statistical difference (P&gt;0.05) for the consumption and digestibility of nutrients, except for organic matter (OM) and ethereal extract (EE). There was an interaction (P&lt;0.05) between the suckling system and sexual class for the OM and EE intakes, as well as for the average daily gain, in which HS 49 males presented higher averages in relation to SA 30. The bioeconomic performance of male calves from the lactation system 49 was superior and presented the best cost-benefit ratio among the systems studied.
