title: LINEAR AND NON-LINEAR EQUATIONS TO PREDICT THE BEHAVIOR OF PHYSICO-CHEMICAL PROPERTIES OF AVIATION FUEL MIXED WITH ALTERNATIVE BIOQUEROSENE DROP-IN

description: Density, viscosity and calorific values are important physical properties to affect the utilization of biofuel. In this work, mixtures of farnesane and a “jet fuel”, QAv-1, were used to study the variation of density and kinematic viscosity as a function of the volumetric fraction of farnesane and temperature. Experimental measurements were carried out for nineteen farnesane blends and pure farnesane and QAv-1, at four temperatures in the range of 293 - 323 K. Variation of high heating (HHV) and low heating (LHV) values were also determined for different blends of farnesane/QAv-1. Several empirical correlations were used to predict the density, the kinematic viscosity, HHV and LHV values. By using some of these empirical correlations, the estimated values of those three properties studied are in excellent agreement with the experimental data, with low absolute average prediction error.

title: Study of K-40, Ra-226, Ra-228 and Ra-224 activity concentrations in some seasoning and nuts obtained in Rio de Janeiro city, Brazil

description: Abstract This work presents an investigation of the activity concentration (AC) of naturally occurring radionuclides in 26 samples of seasoning and nuts utilized for Brazilian population. The samples were measured using gamma spectroscopy technique with a high-purity germanium detector. The analysis shows that K-40 AC was measured in all samples, and its AC ranges from 21.0 Bq/kg to 1288 Bq/kg. The highest K-40 AC was measured for cheiro verde, a Brazilian seasoning made of chives (Allium schoenoprasum) and parsley ( Petroselinum crispum), while annatto, made with the fruit of Bixa orelhana , presented the lowest AC. Brazil nut (Bertholletia excelsa ) presented the highest AC for Ra-226 and Ra-228 with 24 Bq/kg and 25.7 Bq/kg, respectively, and black pepper (Piper nigrum) presented the highest Ra-224 AC, with 33.9 Bq/kg. Behavior of radionuclides present in the seasoning samples and dose percentage due to ingestion was evaluated. The highest effective dose for members of the public due to idealized intake of 1 kg of seasoning was 23.5 µSv/y due to Brazil nut and the lowest effective dose was found for annatto: 0.13 µSv/y. The Syrian seasoning was the only sample that presented a measurable amount of Cs-137, (6.1 ± 1.1) Bq/kg for AC and 0.08µSv/y for effective dose.

title: Surgical Treatment for Congenital Heart Defects in Down Syndrome Patients

description: Abstract Objective: To analyze data related to surgical treatment in patients with congenital heart defects (CHD) and Down syndrome (DS) based on information from International Quality Improvement Collaborative Database for Congenital Heart Disease (IQIC). Methods: Between July 1, 2010 and December 31, 2017, 139 patients with CHD and DS underwent surgery at Hospital de Base and Hospital da Criança e Maternidade de São José do Rio Preto (FUNFARME)/Faculdade de Medicina de São José do Rio Preto - SP (FAMERP). A quantitative, observational and cross-sectional study was performed in which the pre, intra and postoperative data were analyzed in an IQIC database. The data included gender, age, prematurity, weight, preoperative procedures, diagnosis, associated cardiac and non-cardiac anomalies, Risk Adjustment for Congenital Heart Surgery (RACHS-1), type of surgery, cardiopulmonary bypass (CPB), perfusion time, aortic clamping time and CPB temperature, bacterial sepsis, surgical site infection and other infections, length of stay in intensive care unit (ICU), length of hospital stay and in-hospital mortality. Results: The most prevalent procedures were complete atrioventricular septal defect repair (58 - 39.45%), followed by closure of ventricular septal defect (36 - 24.49%). The RACHS-1 categories 1, 2, 3 and 4 were distributed as 22 (15%); 49 (33.3%); 72 (49%) and 4 (2.7%), respectively. There were no procedures classified as categories 5 or 6. Bacterial sepsis occurred in 10.2% of cases, surgical site infection in 6.1%, other infections in 14.3%. The median length of ICU stay was 5 days and the median length of hospital stay was 11 days. In-hospital mortality was 6.8%. Conclusion: Surgical treatment in patients with CHD and DS usually does not require highly complex surgical procedures, but are affected by infectious complications, resulting in a longer ICU and hospital length of stay with considerable mortality.

title: INFLUENCE OF DIFFERENT THERMAL ENVIRONMENTS ON THE PERFORMANCE OF LAYING HENS DURING THE INITIAL STAGE OF REARING

description: ABSTRACT This study was conducted with the aim of assessing the effects of different ambient temperature values on the performance of laying birds from one to 42 days of age in order to obtain optimal comfort temperatures. A total of 864 laying hens were distributed in four climatic chambers with different temperature ranges. One of the chambers was maintained within the thermal range recommended by the literature and the others were maintained under temperatures that consisted of mild and moderate cold stress and moderate heat stress. The experiment was conducted according to a completely randomized design in a split-plot arrangement and six replications. The data were analyzed by means of the analysis of variance and regression. The final performance of birds with temperatures of 33, 28, 26, 23, 19, and 19 °C (for the first, second, third, fourth, fifth, and sixth week of age, respectively) presented better productive results, confirming the assertiveness regarding the best thermal comfort and welfare of laying birds during the rearing stage. The results showed that under conditions of cold thermal stress, birds presented a worse performance, thus affecting their development and productive efficiency.

title: Communicative and strategic planning-action approach: social technology for the planning of postgraduate programs

description: Abstract The Communicative and strategic planning-action approach methodology (CSP) combines strategy and communicative rationality. It is coherent and enables strategic planning when applied to socially constructed contexts, such as in graduate programs (PPG). This study reports the experience of the Graduate Program in Environmental Sciences (GPES) of the Federal University of Rondônia (UNIR) using the CSP in the 2015/2016 Planning, setting the bases for the planning process of other graduate programs of the univeristy. This is a qualitative and applied research, adopting a descriptive approach and using participatory procedures. The data were collected from research diaries where participant observation was registered, and from semi-structured forms used to obtain feedback about the planning process with the participants. The data collected was then submitted to descriptive and content analysis. Twenty-one professors participated in this process. A planning team was formed including professors from the GPES to adapt and apply the CSP. The planning process was structured in three rounds with meetings in two cities in order to write the GPES Development and Consolidation Plan for 2015/2016. It was possible to observe the positive results obtained in the planning process since the participants recognized the method’s capacity to gather them to establish dialogues and connections regarding their projects, also facilitating a shared understanding about the programs context. The planning process originated a methodological proposal adapting and contextualizing the CSP in order to be used in other graduate programs of UNIR. The results show that the CSP is a useful social technology to improve graduate programs, helping them to achieve their potential, structuring the basis for the dialogue between the program and its environment, producing actions of scientific and social impact.

title: Characteristics of scientific collaboration among research groups in areas of exact sciences, biology and humanities

description: Abstract This study aims to characterize the scientific collaboration (SC) among research groups, active in the different areas of knowledge (exact sciences, biology, and humanities). It addresses the reasons for collaboration; interaction dynamics; facilitator aspects, challenges, problems and difficulties faced; main results achieved; and learned content. It is a theoretical, empirical, descriptive and qualitative research, based on a literature review that describes the panorama of studies on this subject. Data collected by semi-structured interview were organized in categories of analysis defined “a priori” and submitted to content analysis. The results identified that collaboration is driven by the need to meet the requirements of funding agencies and are aimed especially at: 1) the expansion of studies and research, with diversification of theoretical and methodological perspectives, with the objective of obtaining greater knowledge about the subject, in addition to the use and exchange of knowledge and experience of other members of the SC; and 2) sharing of financial resources and equipment. The proximity of the research groups line of study and the prior relationship among the researchers, which is gained in opportunities of study and interaction (events), contribute to form partnerships for scientific collaboration. There is an overlap between challenges, problems, hindering and facilitating aspects, with the presence or absence of certain conditions determining how the aspect is perceived. Among the main results are the best use of resources, quality improvement, production expansion, and the knowledge dissemination. In addition to focusing on the theme in the context of Brazilian research groups of different areas of knowledge, the study contributes to the identification of contents learned in the performance in SC.

title: THE TECHNOLOGICAL LEVEL OF AGRICULTURAL MECHANIZATION IN THE STATE OF CEARÁ, BRAZIL

description: ABSTRACT Agricultural mechanization is a significant factor of agricultural modernization, but there are few data on the technological levels of this mechanization in the State of Ceará, Brazil. To study this topic, we designed a structured questionnaire, and interviews were conducted across the state. The survey data made it possible to calculate an index of agricultural mechanization technology and study hypotheses specific to farms of Ceará. The results indicate that the technology levels are different between farms of different sizes: large and medium farms are level I-M5 (automation), while small farms ranged from level IV-M1/M2 (primary/animal) to III-M3 (preliminary). We conclude that public policy for training should be directed at small farms. There is a need to show new production alternatives to small farmers, which leads to savings, and increases the profitability of the activity.

title: Business models in the public domain: the public governance canvas

description: Abstract This study aims to put forward a public governance ontology, based on robust business literature and a structured public governance concept, to aid in improving understanding, communication, innovation, and measurements in public ventures. The ontology approach is combined with design science to develop a “public governance canvas model,” which conveys different descriptions of governance arrangements of given public ventures. The product of this research is a model that forms the ideal structure of new strategic management and information tools, as well as offers other benefits relating to measurement and evaluation. Finally, the canvas model is applied in three different institutional contexts of public management. Further development of this review could be accomplished by applying this model to organizations that generate important outcomes for both practitioners and academics.

title: Communication that constitutes and transforms subjects: communicative action in Jürgen Habermas, dialogical action in Paulo Freire and Organizational Studies

description: Abstract This essay presents contributions by Jürgen Habermas and Paulo Freire for the constitution of critical-reflexive subjects and the implications in the teaching-research-extension processes in the field of Organizational Studies. We show that intersubjectivity and dialogicity are conditions for the understanding between subjects and it is precisely through these conditions that the subjects are constituted, in a process that is dialogical, pedagogical and political. Freire and Habermas offer elements to deconstruct dominant instrumental logic and provide the basis for the reconstruction of unprecedented-viable possibilities of ways of organizing and managing. Therefore, this article highlights the importance of Organizational Studies to broaden the focus of teaching-research-extension possibilities and directs them to a communicative and dialogic engagement, beyond the borders of universities. This reconstruction indicates that researchers participate in different public arenas, debate and build public problems, processes of resistance, visibility, and dramatization of problematic issues. Observing the contributions of Freire and Habermas, Organizational Studies as a field cannot be limited to developing a critique, from a distant point of view: it is necessary to co-participate, co-act, co-operate and co-construct with its public.
