title: WATERMELON YIELD AND EFFICIENCY OF USE OF WATER AND NITROGEN

description: ABSTRACT The evaluation of the yield of crops and their efficiency of use of water and nitrogen is essential to optimize the management of production factors. The objective of this study is to evaluate the effect of irrigation regimes and nitrogen doses in fertigation on fruit yield and efficiency of use of water and nitrogen by the Top Gun watermelon hybrid. The study was conducted in Bom Jesus, Piauí, Brazil, from August 4 to October 15, 2015. The study used a completed randomized block design with four repetitions, five irrigation depths (110.17, 156.86, 221.16, 268.87, and 317.09 mm), and five doses of nitrogen in fertigation (0, 50, 100, 150, and 200 kg ha-1 applied as urea). Fruit yield and water use efficiency were not affected by nitrogen doses; however, there was a significant interaction of the factors for the efficiency of nitrogen use. The highest yield (39,549.45 kg ha-1) was obtained using 233.48 mm of water during the growth cycle. The water depth that promoted the maximum efficiency of water use was 110.42 mm, and nitrogen use was most efficient using 232.21 mm of water and 50 kg ha-1 of nitrogen.

title: Comparative analysis of niobium and vanadium carbide efficiency in the high energy mechanical milling of aluminum bronze alloy

description: Abstract This study aims to analyze the efficiency of niobium and vanadium carbides in the high energy mechanical milling of aluminum bronze alloy. Two series of experiments were made following the same steps for both niobium carbide (NbC) and vanadium carbide (VC) additions: 30 g of chips were weighed and placed in a stainless steel jar with 3 % of carbide and 1 % of stearic acid for a mass/sphere relationship of 1:10. The milling was realized using a planetary ball mill for 10, 30 and 50 hours in an inert argon atmosphere at 300 rpm. Results shown in laser diffraction indicate a great reduction in the particle sizes of powders when VC is used. For 30 hours milling, D50 values ranged from 1580 µm with NbC to 182.3 µm with VC addition. The D50 values ranged from 251.5 µm with NbC to 52.26 µm with VC addition, for 50 hours milling. The scanning electron microscopy showed that in 10 hours of milling, the energy was not sufficient to achieve the shear of chips in both cases. For 30 hours, it's possible to observe particles with sizes between 100 µm and 800 µm with NbC addition while for the same milling time, with VC it's possible to see particles with different sizes, but with many shapes of fine particulates. For 50 hours milling, particles achieved the smaller sizes between 50 and 200 µm with NbC and ranging from 5 until 50 µm with VC addition.

title: THE PUBLIC LIBRARY OF BIG FIELD IN THE YEARS 1930 BY THE PAGES OF THE MAGAZINE FOLHA DA SERRA

description: ABSTRACT The objective of this research is to analyze the campaign for the creation, implantation and operation of the Campo Grande Public Library, south of Mato Grosso, in the 1930s, propagated in the pages of Revista Folha da Serra (RFS, 1931-1940). The relationship between RFS and the emergence of the Campo Grande Public Library Society, the creator and maintainer of the Library in question, is questioned. With a theoretical-methodological reference anchored in the New Cultural History, the analysis includes the press as an important source of research for the history of education, in an educational perspective beyond the walls of the school (CHARTIER, 1990; CATANI; BASTOS, 2002; BICCAS, 2008). It is concluded that the Public Library implemented by RFS in Campo Grande in the 1930s, with its events, contests and debates influenced new habits, behaviors and knowledge, contributing to the formation and expansion of readers in the region, thus expanding the potential audience of RFS.

title: Design and study of urban form using shape grammars

description: Abstract The main goal of this paper is to present shape grammars as an analytical tool to study urban morphology and as a design tool for urban planning. Shape grammars emerged in the 70s through the seminal article by Stiny & Gips, and are used to analyse past design styles (analytical grammars) as well as to create new and original design languages (original grammars). In this paper, the formalization of shape grammar is introduced and the relevance of its use in different contexts is discussed. With this in mind, the paper highlights the extent to which shape grammars can be used as part of a methodology for a flexible urban design that responds to the requirements and needs existing in urban and built environments. The paper also presents a state of the art of shape grammars for urban design and several case studies both concerning analytical studies of urban space and proposals for new urban planning. Currently available and under development digital tools that use shape grammars for urban design are presented at the end of the paper.

title: AGRONOMIC BIOFORTIFICATION OF BEET PLANTS WITH ZINC VIA SEED PRIMING1

description: ABSTRACT One-fifth of the world's population consumes too little zinc (Zn) causing deficiencies that can damage cells, stunt growth, and decrease immune response. This study evaluated the effect of time on the priming of beet seeds, in solutions enriched with Zn, on physiology, growth, production, and root biofortification. Two greenhouse experiments were conducted during spring 2015 and autumn 2016. In each experiment, 24 treatments were tested which comprised various combinations of three Zn concentrations (0, 10, and 30 mg mL-1), two Zn sources (sulphate and chloride), and four time periods (12, 16, 20, and 24 h), arranged in a randomised block design with four replicates. The concentration of Zn, mainly as sulphate, affected all parameters evaluated in the beet plants, such as fresh and dry root mass, photosynthesis, and root Zn concentration (biofortification). Compared to the control, fresh root mass increased 70 and 100 g per plant with 10 mg mL-1 of Zn during the experiments in 2015 and 2016, respectively. The same concentration for 16 h produced the highest Zn concentration in the roots, achieving 121 and 42 mg kg-1 in 2015 and 2016, respectively. Priming seeds in solutions enriched with Zn, thus, benefited the physiological response of the beet plants by promoting increases in growth, production, and biofortification of beet roots. Therefore, this method can be used to biofortify beet plants agronomically, regardless of the Zn source.

title: Surgical management of palatine Torus - case series

description: INTRODUCTION: Torus palatinus is a specific name to identify exostoses developed in the hard palate along the median palatine suture. Despite of not being a pathological condition, its presence requires attention and knowledge regarding its management. Surgical removal of exostoses is indicated when the patient frequently traumatizes the area of palatine torus during mastication and speech or when it is necessary for the rehabilitation of the upper arcade with complete dentures. OBJECTIVE: The aim of this article is to present three cases of Torus palatinus and to discuss the management of them. CASE REPORT: In the first case, a 57-year-old Caucasian man sought oral rehabilitation of his edentulous maxilla but presented a hard nodules in the hard palate; in the second case, a 40-year-old Caucasian woman was referred for frequent trauma of palatal mucosa during mastication, aesthetic complaint, and discomfort caused by the trauma of her tongue in this area; and in the third case, a 45-year-old Caucasian woman presented with a lesion on the palate that caused difficulty swallowing. When the Torus palatinus was impairing the basic physiological functions of the patients, all cases were surgically treated, improving the patients' quality of life. FINAL CONSIDERATION: The dentist should be properly prepared to choose the best from among the existing surgical approaches for each individual lesion in order to improve the results and avoid possible complications.

title: Analysis of the presence and location of mast cells in periapical cysts and periapical granulomas

description: ABSTRACT Objective: The aim of the present study was to locate mast cells in chronic periapical lesions (granulomas and cysts) by using histochemical techniques and toluidine blue staining. Methods: A quantitative, descriptive, cross-sectional and retrospective research was performed. The sample was obtained from histopathological reports in the archives of the laboratory of surgical pathology of the University of Pernambuco between November 2014 and May 2015. Results: Sixteen cases of granuloma and 21 cases of periapical cysts were selected. The stained slides were analyzed by two examiners at different times, in a double-blind study. Mast cells were found in 13 (61.9%) of the periapical cyst cases, located in the capsule of the lesion. In the periapical granuloma cases, mast cells were found in eight cases (50%), located in the granulation tissue. Conclusion: Mast cells were detected in both cysts and periapical granuloma, located in the capsule and granulation tissue, respectively. Mast cells were more prevalent in periapical cysts than in periapical granuloma.

title: Mild cognitive impairment (MCI) and dementia in a sample of adults in the city of Bogotá

description: ABSTRACT The low prevalence of dementia described in communities is likely due to the low sensitivity of screening tests and an absence of evaluation by specialists. OBJECTIVE: To estimate the prevalence of mild cognitive impairment (MCI) and dementia in adults older than 50 years. METHODS: A two-phase, cross-sectional study was conducted by specialists to evaluate cognition and associated demographic risk factors in 1,235 independent community-dwelling adults from Bogotá. In Phase I, screening was performed using the MMSE and MoCA tests. In Phase II, after application of a comprehensive neuropsychological battery with neurologic and psychiatric evaluations, a cognitive diagnosis was established by consensus. RESULTS: The prevalence found for MCI was 34% and for dementia was 23%. MCI was associated with incomplete high school, OR=1.74 (95%CI=1.23-2.45), and with an age of 70-79 years, OR=1.93 (95%CI=1.47-2.53). A total of 73% of MCI cases were amnestic. Dementia was associated with incomplete primary education, OR=8.98 (95%CI=5.56-14.54), complete primary education, OR=6.23 (95%CI=3.70-10.47), and age older than eighty years, OR=3.49 (95%CI=2.23-5.44). CONCLUSION: The prevalence of dementia found was greater than the rates reported in previous studies. Low educational level was the main risk factor for cognitive impairment and should be considered in strategic planning for the local health system.

title: Characterization of water quality parameters in the port area of Barcarena, PA, Brazil

description: Abstract Companies in the industrial hub of Barcarena-PA city use raw materials, supplies and energy that generate solid waste, industrial effluents and domestic sewage that are released in water bodies, changing their physical, chemical and microbiological characteristics. To determine the influence of the companies located in the industrial hub of Barcarena, a study was conducted in a stretch of Pará River under the influence of industrial effluents released by operating companies. Four sampling sites were therefore selected where two campaigns were conducted, one held in the less rainy period and another in the rainy season. Within each field, samples were collected simultaneously at four sample points over a period of 12 hours with 90 minute intervals starting and ending at the end of the ebb tide. We collected 36 samples in the 4 selected points in each sampling campaign of the tide, totaling 72 samples in the two campaigns. Samples were analyzed for pH, temperature, conductivity, total dissolved solids (STD acronym in Portuguese), color, sodium, calcium, potassium, chloride, alkalinity and toughness. The ANOVA test of two factors was used in order to observe whether the variables showed significant differences between the sampling points and seasonality at a 95% significance level. The Water Quality Index (IQA-CETESB) was also calculated. Statistical tests showed that the location of the sampling sites had no influence on the average levels of pH, however there was a significant influence on the other variables. Regarding seasonality, there was no significant difference in all variables, except for chloride and alkalinity. The water samples showed IQA of excellent and good quality.

title: Soft Power, Hard Aspirations: the Shifting Role of Power in Brazilian Foreign Policy

description: Journalists and policy analysts have highlighted the emergence of Brazil as a regional power. However, little attention has been paid to its foreign policy strategies. Brazil's rise to prominence in world politics represents the historical culmination of a foreign policy featuring two main strategies – persuasion and consensus building – both of which emphasise the use of soft power. We analyse four current foreign policy initiatives: the campaign for a permanent seat on the UNSC; the development of a nuclear submarine; Brazil's leadership of the UN peacekeeping mission in Haiti; and government support for Brazilian multinationals. We suggest a growing tension between these initiatives and the two strategies identified above. These initiatives reflect the view current among some policymakers that if Brazil is to rise as a global power it must play by the rules of great power politics.
