title: Submerged Friction Stir Welding of 6061-T6 Aluminium Alloy under Different Water Heads

description: The aim of this paper is to determine the feasibility of submerged friction stir welding of 6061-T6 aluminium alloy on different water heads through macrostructuralanalysis.In this work, aluminium 6061-T6 alloy was friction stir welded under normal and submerged conditions at different rotational speeds of 400 rpm, 800 rpm, 1200 rpm, 1600 rpm. The water head was varied from 10 to 30 mm in the case of thesubmerged friction stir welding process. In both normal and submerged friction stir welding processes, a welding speed of 45 mm/min, a normal load of 30 kN, tool tilt angle of 2˚, depth of tool penetration and tool geometry were kept constant. Torque is measured during the welding process, and power (kW) is calculated after the welding process. The macrostructural analysis was carried out for locating defect formation and identifying the feasible working range of process parameters of the welded aluminium 6061-T6 alloy. The mechanical properties such as ultimate tensile strength and microhardness of submerged friction stir welded of 6061 aluminium alloys were investigated.Scanning Electron Microscope (SEM) metallography was used for comparing the microstructure of the parent material, friction stir welded and submerged stir welded samples.

title: Particle Physics game: Discovering the Higgs boson

description: Abstract In this article it is proposed the use of a didactic game as a methodological complementation to teach High Energy Physics, addressing the theme of Elementary Particle Physics. The idea is to use playful and fun strategies to teach phenomena studied in the Hadron Large Collider (LHC), leading the participants to make new scientific discoveries, acquire knowledge and construct concepts that will be used in the formulation of the Higgs boson theory and its detection in the ATLAS experiment. Although such concepts have an extremely complex quantitative description, to some extent rooted in experimental analysis, it is possible to make it qualitatively accessible without having to resort to advanced mathematical formulations, while retaining its technical character.

title: CASE STUDY OF CONGENITAL ANOMALIES OF THE UPPER LIMB IN REFERENCE AMBULATORY CARE FACILITY

description: ABSTRACT Objective: The epidemiological profile of congenital anomalies of the upper limbs (CAULs) is of major relevance to monitoring and planning. A study of this profile may reveal if there is prevalence of some specific type of malformation in comparison to a more comprehensive epidemiological sample. The Latin American Collaborative Study of Congenital Malformations (ECLAMC) has an extensive database, providing an excellent source of comparison. This study aims to evaluate the epidemiological profile of CAULs at the hand surgery department of the Hospital Federal da Lagoa (HFL) in Brazil, and compare it to the ECLAMC data. Methods: We conducted a retrospective analysis of patients who underwent treatment at the pediatric outpatient hand surgery clinic. The sample universe consisted of 126 patients (4 of these patients presented with 2 simultaneous anomalies), totaling 130 malformations. Results: The results demonstrated that the comparable pathologies have significantly similar incidence rates. It is worth noting the polydactylies (pre- and post-axial), where the percentile of incidence in the ECLAMC was higher. Conclusion: This study showed that the epidemiological profile of patients who underwent treatment at this hospital was equivalent to that found in the ECLAMC database. Level of evidence III, Retrospective epidemiological study.

title: Effects of ranibizumab and amfenac on the functional abilities and radiosensitivity of uveal melanoma cells

description: ABSTRACT Purpose: To evaluate the effects of ranibizumab and amfenac in human uveal melanoma cell lines and to explore the ability of these compounds to sensitize uveal melanoma cells to radiation therapy. Methods: The 92.1 human uveal melanoma cell line was cultured and subjected to the proposed treatment (ranibizumab, amfenac, and a combination of both). Proliferation, migration, and invasion assays of the 92.1 uveal melanoma cell line were assessed after pretreatment with ranibizumab (125 mg/mL), amfenac (150 nM), or a combination of both. In addition, proliferation rates were assessed after treatment with ranibizumab and amfenac, and the cells were subsequently exposed to various radiation doses (0, 4, and 8 Gy). Results: Proliferation assay: cells treated with a combination of ranibizumab and amfenac had lower proliferation rates than controls (p=0.016) and than those treated with only ranibizumab (p=0.033). Migration assay: a significantly lower migration rate was observed in cells treated with amfenac than the control (p=0.014) and than those treated with ranibizumab (p=0.044). Invasion assay: there were no significant differences among the studied groups. Irradiation exposure: in the 4 Gy dose group, there were no significant differences among any groups. In the 8 Gy dose group, treatment with ranibizumab, amfenac, and their combination prior to application of the 8 Gy radiation led to a marked reduction in proliferation rates (p=0.009, p=0.01, and p=0.034, respectively) compared with controls. Conclusion: Combination of ranibizumab and amfenac reduced the proliferation rate of uveal melanoma cells; however, only amfenac monotherapy significantly decreased cell migration. The radiosensitivity of the 92.1 uveal melanoma cell line increased following the administration of ranibizumab, amfenac, and their combination. Further investigation is warranted to determine if this is a viable pretreatment strategy to render large tumors amenable to radiotherapy.

title: State capacities for infrastructure policies in contemporary Brazil

description: Abstract This article aims to discuss the capacities of the Brazilian State, particularly the Federal Executive Branch, to produce efficient infrastructure policies that deliver the expected benefits and also obtain support (or consent) from impacted social groups. We argue that the professionalization and technical knowledge of the federal government’s public bureaucracy are constrained by low levels of autonomy and intragovernmental cohesion. Likewise, the relationship between the federal bureaucracy and local civil society, subnational governments and accountability agencies are precarious. This situation represents a barrier to the efficiency and legitimacy of state action in the sector.

title: The end of the dissemination of Enem results per school, a brief reflection on the evaluation of public policies and access to information

description: Abstract This study aims to create a favorable scenario for the discussion about the decision of the Ministry of Education (MEC) to stop disseminating the results of the National High School Examination (Enem) per school. At first, the issue was contextualized and problematized under legal and public administration aspects. Then, statistics were compiled from the organization of data obtained in the “per-school” spreadsheets of previous years, to demonstrate the contribution of this information to the evaluation of the new public policies focused on education. The conclusion presents the main results of the quantitative data analysis, and from there the main aspects of the theoretical discussion are revisited.

title: ARTHROSCOPIC ASSESSMENT OF THE WRIST WITH KIENBÖCK’S DISEASE

description: ABSTRACT Objective: Treatment of Kienböck's disease is challenging and the variability of results, despite the surgical technique, shows that there must be other aspects that can influence outcomes. The objective of this study is determine, through arthroscopic approach, the pattern of impairment of the carpal bones in Lichtman stage III patients. Method: Wrist arthroscopy was performed in patients with symptoms and evidence of lunate necrosis on x-rays, with signs of 3A and 3B stages. The Outerbridge classification was used to grade the articular status of the carpal bones. Results: Fifteen patients with stage 3 disease were assessed, five of whom were staged as type 3A and ten as 3B using the Lichtman stages. According to the Outerbridge classification, the lunate sulcus was the most affected with means of 2.8 at 3A and 2.9 at 3B. Other areas were significantly less affected with means of 1.1 and 1.3, respectively. Conclusion: Arthroscopic assessment of the wrist could aid in surgical decision making, offering more details on cartilage status in stage 3 Kienböck's disease. Level of Evidence III, Study of nonconsecutive patients, without consistently applied reference “gold” standard.

title: Epistemologia da Ciência da Informação: evolução da pesquisa e suas bases referenciais

description: Abstract The present research analyzes the evolution of scientific production on the epistemology in the area of Information Science. It also seeks to present prominent authors and the main referencials used in the selected articles. Asks whether the increase in the number of articles publications on epistemology can mean the consolidation of a research community. By extension, presents the possibility of identifying philosophical and scientific traditions through the referencials of a corpus of analysis. It defends the hypothesis that the increase of the production on epistemology in Information Science indicates the recognition and relevance of this subject in the last years. Surveys were carried out in 30 scientific journals of Information Science, from 1972 to 2015, and 164 articles were selected for the analysis. The distribution of selected articles evidenced a significant increase in research from 2004. Faced with the increase in production, the general framework of authors and referencials stands out for the tradition, plurality and constant updating of their points of view. Highlights the need to encourage the spontaneous nature of research on the subject in the universe of undergraduate and postgraduate studies. It concludes that there is an indicative of consolidation of the research and, mainly, the formation of a scientific community around the epistemology of Information Science.

title: Salinity reduces nutrients absorption and efficiency of their utilization in cassava plants

description: ABSTRACT: The objective of this research was to evaluate the influence of salinity on the absorption and utilization of nutrients by cassava. For the study, cassava was submitted to four saline concentrations: 0, 20, 40, and 60mM NaCl. Results showed that the absorption of all nutrients, except nitrogen (N), was reduced by salinity, with highest reduction for potassium (K). However, all nutrients were maintained at concentrations which did not indicate mineral deficiency problem. The abnormal concentration of calcium in the tuberous roots may have been one of the factors that contributed to the lower growth of this organ and of the plant as a whole. Transports of nitrogen, potassium, phosphorus and sulfur from root to the aerial part was higher under salinity treatment. Efficiency in the use of all the nutrients, mainly N, was reduced due to salinity. Given that: (i) the absorption of K was the most impaired, (ii) there was abnormal accumulation of Ca in tuberous roots, and (iii) the efficiency in the use of N was the most affected, it is suggested to prioritize studies on these three issues, as a way to better understand the aspects related to the tolerance/sensitivity of cassava plants to salinity.
