title: Tillering of piatã grass subject intermittent cutting

description: ABSTRACT The aim of this study was to evaluate the tillering of Brachiaria brizantha cv. Piatã, as a basis for identifying the frequencies and post-cutting heights most suitable for this grass. In a 2 x 2 factorial scheme, combinations between two cut frequencies (95% and maximum light interception, IL max ) and two post-cut heights (15 and 20cm) were studied. The experimental design was in randomized blocks with 3 replicates, totaling 12 experimental units of 14m 2 each. Rates of appearance (TAR) and mortality (TMR) of tillers, the stability index and the population density of tillers were evaluated. The highest TAR in the canopy under 95% IL occurred in Summer 1, in comparison to the other seasons. In the canopies managed with IL max , TAR was higher in summer 1 and in autumn, when compared to other seasons. In summer 1 and at the end of spring and summer 2, there were the highest TMR for the two cutoff frequencies evaluated. In autumn, TMR was also high in the canopy cut with IL max . IE was lower during summer 1 in the canopy under IL max and 15cm of residue (0.995). However, at other times, stability index values were greater than one unit and were not influenced by post-cut frequency and height. The population density of tillers was lower in Summer 1, when compared to the other seasons. The piata grass may be defoliated with any combination of light intercepts, 95% and ILmax, and post-cut heights, 15 or 20cm, without impairing the persistence of pasture.

title: What is superexploitation?

description: Abstract What is the superexploitation of labour power? How does superexploitation operate? What are its impacts on the working class? This paper aims to answer these questions, showing how the category introduced by Ruy Mauro Marini can be comprehended in accordance with the Marxist theory of value and how it relates to the determination of the value of labour power. The text has been written in order to contribute both to a broader understanding of this category and to present it for those who are not knowledgeable about the dependency debate.

title: Cervical cancer: knowledge, attitude and practice on the prevention examination

description: ABSTRACT Objective: to evaluate the knowledge, attitude and practice of women on the cervical-uterine cancer screening and to investigate their association with sociodemographic variables. Method: a cross-sectional study, carried out from July to September 2015, with 500 women enrolled in the Basic Health Units of the Health District V, of the city of Recife-PE. For data collection, a semi-structured form was used. In statistical analysis, the Chi-square test and Fisher’s Exact Test were applied and, in the multivariate analysis, the Poisson model and Wald statistic. Results: the prevalence of adequate knowledge, attitude and practice was 35.2%, 98% and 70.6%, respectively. Adequate knowledge was associated with having no children, having a family income of two minimum wages and Spiritist/Afro-Brazilian religion. Conclusion: women carry out the examination, deem it necessary, but do not have adequate knowledge, which demonstrates the need for educational actions by nurses and other health professionals.

title: Capital taxation: theory and práxis (and the Brazilian case)

description: Abstract This paper shows how the theoretical assumptions that supported the current model of income taxation in Brazil (and in other countries influenced by the liberal ideology) are undergoing a significant international revision as a consequence of the increase in inequality and the maturation of the theory of optimal taxation. This review indicates that both the progressivity and the taxation of capital income can be made compatible in a neoclassical framework that seeks a balance between the search for equity and economic efficiency. In particular, it is concluded that: the total exemption of distributed profits and dividends, as takes place in Brazil, does not guarantee the neutrality sought by neoclassical models based on more realistic hypotheses about the behavior of economic agents; the dual income tax model, in the different formats adopted by the Nordic countries, can serve as a reference for a reform that will guarantee alignment of the treatment of capital incomes and, at the same time, a greater burden on extraordinary incomes.

title: Effects of cover crops on soil hydraulic properties and yield in a persimmon orchard

description: ABSTRACT This study evaluated the effects of cover crops on yield and soil hydraulic properties of a persimmon orchard in Turkey. Soil samples were taken from 0-20 and 20-40 cm. Profiles of a clay soil and field capacity, permanent wilting point, available water capacity and saturated hydraulic conductivity of the samples were determined. Festuca rubra subsp. rubra, Trifolium repens, Festuca arundinacea, a mixture of them [Trifolium repens (40%) + Festuca rubra rubra (30%) + Festuca arundinacea (30%)], Vicia villosa R., and Trifolium meneghinianum were used as the cover crops. The experiment was conducted in a randomized complete blocks design with four replications including a mechanically cultivated and herbicide treated control plots. The greatest mean persimmon yield (16.2 Mg·ha-1) was observed in the Vicia villosa treatment and the lowest mean yield (3.6 Mg·ha-1) was observed in the bare control. The cover crops increased soil hydraulic properties, with increased aggregate stability, total porosity, reduced bulk density, and penetration resistance. The greatest increases in organic matter contents at 0-20 cm soil depth in the persimmon orchard were observed in the Vicia treatments (73.4% in the first and 74.5% in the second year). The highest aggregate stability (67.4%) and total porosity (60.9%) values were obtained on the Vicia treatments. To increase persimmon yield and improve soil physical and hydraulic properties, cover crops, especially Vicia villosa and Trifolium repens are suggested for clay soils.

title: Package of menthol measures for thirst relief: a randomized clinical study

description: ABSTRACT Objective: To evaluate the effectiveness of the menthol package (lip hydration and ice popsicles) compared to a package of non-menthol measures (lip hydration and ice popsicles) as a way to relieve thirst in patients in the Anesthetic Recovery Room. Method: Randomized and parallel trial study, with 120 patients randomized patients in an experimental group - menthol measurements (n=59) and control group - measures without menthol (n = 61). Results: There was a significant (p&lt;0.05) decrease in intensity, hydration, dryness and taste in the oral cavity between the three moments of assessment/intervention in the two groups. The difference was significant in the experimental group for thirst intensity at the second assessment/intervention point (p&lt;0.05) after a single administration of the menthol package. Conclusion: There was a reduction in thirst intensity in both groups. Patients who received menthol packages showed a significant decrease in intensity after a single evaluation/intervention time. NCT: 02869139.

title: Individualized parameterization of multiparametric monitors alarms in infarcted patients

description: ABSTRACT Objective: To measure the magnitude of the effect of an individualized parameterization protocol for hemodynamic alarms in patients with acute myocardial infarction. Method: Pragmatic clinical trial, open label and single arm, whose intervention was performed through a protocol validated and tested in 32 patients using multiparametric monitors. The heart rate, blood pressure, respiratory rate, oxygen saturation and ST segment-monitoring were measured and classified for clinical consistency one hour before and after the intervention, for 64 hours. Results: The protocol obtained Content Validity Index of 0.92. Of the 460 registered alarms, 261 were considered inconsistent before the intervention and 47 after it. The Relative Risk of inconsistent alarms after the protocol was 0.32 (95% CI 0.23-0.43, p &lt;0.0001). Conclusion: The protocol proved to be a protective factor to the appearance of inconsistent clinical alarms of multiparametric monitors.

title: Small-sized fish: the largest and most threatened portion of the megadiverse neotropical freshwater fish fauna

description: Abstract: We introduce the work providing a synthetic description of the diversity and phyletic structure of freshwater fish in the Neotropical Region, especially emphasizing that of Brazil. This is accompanied by a discussion about environments of fish from small to medium sized to large, taking into account how it shaped their respective biologies/ecologies, as well as what they imply for their use by humans. We present, as figures, the results of our exploratory analysis of Brazilian Red Book of Threatened Species of Fauna (2018), focusing on the small-sized ones, with up to 15 cm of standard length. We continue to present the main human impacts in small fish environments, along with those suffered by medium to large fish environments, and then follow by their respective deleterious effects. Finally, we present a general synthesis, reinforcing the enormous importance of small fish conservation and their respective preferred environments, followed by our main conclusions, and possible conservation strategies.

title: Infection related to Klebsiella pneumoniae producing carbapenemase in renal transplant patients

description: ABSTRACT Objective: To evaluate the risk factors related to Klebsiella pneumoniae carbapenemase infection after renal transplantation. Methods: This was a retrospective epidemiological (case-control) study, conducted from October 2011 to march 2016. Transplanted patients with infection by this bacteria during hospitalization were selected as cases. The controls were paired by age, sex, type of donor and transplant time. The proportion of cases and controls was 1:2. Results: Thirty hundred and five patients were included in the study (45 cases and 90 controls). The risk factors found for infection by KPC were: time of hospitalization after the transplant (OR: 4.82; CI95% 2.46-9.44), delayed kidney function (OR: 5.60; CI95% 1.91-11.01) and previous infectious for another microorganism ( OR: 34.13 CI95% 3.52-132.00). Conclusion: The risk of acquisition of this bacterium was directly related to invasive procedures and exposure to the hospital environment. The findings reinforce the importance of prevention measures and control of infection by this microorganism.

title: Nurse safety culture in the services of a university hospital

description: ABSTRACT Objective: To evaluate nurse safety culture in a teaching hospital, as well as to verify differences in the safety culture dimensions between services. Method: cross-sectional, quantitative study, conducted from October to December 2015, in a university hospital. The instrument Hospital Survey on Patient Safety Culture was applied. Results: A total of 195 nurses from four different services participated in the study. Significant difference between services were identified for five dimensions of safety culture: organizational learning (P=0.012); return of information and communication about error (P=0.014); management support for patient safety (P=0.001); general perceptions about patient safety (P=0.005); and frequency of event notification (P=0.003). Conclusion: The medical clinic service had the highest statistical difference between the dimensions. These evaluations allow managers to identify the differences between the same hospital’s services, serving as a warning and assisting in the services’ improvement.

title: The use of children’s stories in nursing care for the child: an integrative review

description: ABSTRACT Objective: To identify how children’s stories can be used in child care. Method: Integrative literature review, conducted in databases between 2000 and 2018, in three languages. Full research articles were included that agreed with the following question: “How can children’s stories be used in child care?”. Results: From the analysis of 16 selected articles, three categories emerged: The use of stories in the hospital; Specialized nursing intervention; and Stories in the educational dimension. Final considerations: Evidence shows benefits to children, families, institutions and nursing. The use of children’s stories as a care intervention can occur in different situations and settings, values; boosts bonds, reduces anxiety in children and families, encourages children’s participation in care, and promotes health education. It is a low-cost and still incipient strategy in nursing.
