title: Influence of Curing Conditions on Lime-metakaolin Mortars

description: ABSTRACT This study analyzed the influence of curing conditions on air lime mortars with two types of metakaolin which were used as partial substitutes for lime mass (10%). Flexural strength and compressive strength tests, as well as mineralogical composition ones by X-ray diffraction (XRD), were carried out in specimens after having been cured for 28 and 180 days indoors, at constant temperature and humidity, and outdoors, with no direct exposure to rain. Analyses of microstructure and chemical composition were conducted by scanning electron microscopy (SEM) and by energy-dispersive X-ray spectroscopy (EDS), respectively, in 180-day-old specimens, which were cured outdoors. Comparisons of results of the experimental analysis showed that substitutions were less efficient in environments with low relative humidity.

title: Crop coefficient and water requirement of prickly pear in the Agreste region of Alagoas state, Brazil

description: ABSTRACT Prickly pear cultivation has played an important role in the Brazilian livestock farming, being used as forage for animals in the Northeast region, especially during the drying season, because it is an excellent source of water. Thus, the objective of this study was to estimate the crop coefficient and water requirement of prickly pear in the Agreste region of Alagoas state, Brazil. Prickly pear crop evapotranspiration (ETc) was determined using five drainage lysimeters, made of polyethylene with dimensions of 0.35 x 0.40 m (side and depth). Four soil layers were separated and put into the lysimeters in the opposite sequence, in order to maintain it as close as possible to the initial soil structure. The reference evapotranspiration (ETo) was estimated by the Penman-Monteith, Hargreaves-Samani and FAO-Radiation methods, using climatic data from the meteorological station of the Instituto Nacional de Meteorologia (INMET) in the city of Arapiraca, AL, Brazil. Crop coefficient (kc) was calculated by the ratio between ETc and ETo. The average kc obtained was 0.72, 0.84 and 0.48 for the Penman-Monteith, Hargreaves-Samani and FAO-Radiation methods, respectively. Keeping the soil under field capacity during the experimental period, the total crop evapotranspiration was 637.84 mm, with daily value equal to 4.22 mm d-1.

title: Uma Nota Sobre Consumo Energético, Emissões, Renda e Emprego na Cadeia de Soja no Brasil

description: Abstract This article, based on the breakdown of energy matrices from 2000 to 2014, compatible with the input-output matrices of Brazil, indicates that the Soya Chain in agribusiness accounts for 12.70% of GDP, 12.10% of jobs, 9.80% of energy consumption and 8.70% of CO2 emissions. There was a structural change based on the expansion of soybeans to soybean processing and processing, as well as a significant use of renewable energy that reaches 59.05% of the chain and represents 71.48% of its emissions. Thus, in energy consumption the chain presents activities that reconcile accelerated economic growth with the preservation of the environment.

title: Acinetobacter baumannii infections in Amazon Region driven by extensively drug resistant international clones, 2016-2018

description: BACKGROUND Acinetobacter baumannii is a leading cause of nosocomial infections. This species is characterised by the presence of pandemic lineages (International Clones) that present a broad antimicrobial resistance profile. OBJECTIVE To perform the molecular epidemiology of carbapenem-resistant A. baumannii from a clinical setting in the Amazon Basin, and to characterise their antimicrobial resistance determinants. METHODS The genetic relationship of carbapenem-resistant A. baumannii were assessed by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Class A, B and D β-lactamase genes were screened by polymerase chain reaction (PCR) and sequencing. The antimicrobial susceptibility profile was obtained by Disc-diffusion method and minimum inhibitory concentration (MIC) determination. FINDINGS All carbapenem-resistant A. baumannii strains belonged to three international clones, IC-1, IC-5 and IC-6, the latter recently reported by the first time in Brazil. The major determinant of carbapenem resistance in IC-1 and IC-5 strains was bla OXA-23, associated with ISAba1 and ISAba3, respectively, while IC-6 harboured the bla OXA-72. CONCLUSIONS The A. baumannii epidemiology in Brazilian Amazon Region was unknown. It was demonstrated that A. baumannii XDR international clones were responsible for nosocomial infections in Boa Vista during 2016-2018, revealing that the epidemiological scenario of A. baumannii infections in Amazon Region resembles those from the cosmopolitan regions worldwide.

title: Diffuse Double-harmonic oscillator

description: Abstract The behavior description of diffuse system, linear and nonlinear, can be treated through Fokker-Planck equation. This equation has shown great interesting of researchers for its good adaptation to different systems, classical and quantum. In this work we use the Fokker-Planck to find the total probabilities of diffuse bistable potential under action of a external electric field. The system solutions show that there is two wave functions, one symmetrical and another anti-symmetrical and when the electric field is applied all energy levels are degenerate. It is observed that the application of external electric field entails in a decrease of temperature of the system and, consequently, shorter time to reach equilibrium.

title: The video analysis of a fidget spinner flight: torque and angular momentum

description: Abstract Could the world-famous fidget spinner toy be used in the classroom to illustrate the concepts of moment of inertia, torque and angular momentum? Curiously, there are very few papers related to the topic that have been published so far. In this work, we present a real situation consisting of two extremely simple experimental configurations of oblique launching of a spinner with and without initial spin type rotation. We define spin type rotation as any rotation in which the spinner rotates around one of its main symmetry axes. The technique chosen for data collection was the video analysis, using the free software Tracker. The main results were (i) To present a fast and easy execution experiment that simultaneously approaches the concepts of torque, orbital angular momentum and spin angular momentum. (ii) Analyze in a qualitative way the similarities and differences between the orientations of the orbital and spin angular momenta for two types of oblique launching (iii) Obtain a quantitative estimative of the magnitudes of the spin angular momenta in relation to the respective symmetry axis of the spinner, in both cases.

title: Oral health status of the guarani indigenous population living in southern Brazil

description: Abstract Background The oral health of Brazilian indigenous population has been historically neglected. Recently special attention started through a National Indigenous Oral Health Policy. However, little is known about the epidemiological oral data of these populations, especially in the south of Brazil. Objective To investigate the oral health status of the Guarani Indigenous. Method A cross-sectional study was carried out in 19 villages, totaling 203 subjects. WHO research methods were used. Results The mean DMFT at 12 and 15-19 years was 1.3 and 3.4, respectively. In adults, mean of 11.55 being the component lost (P) 69.3%. Among the elderly, a DMFT of 18.6. The DMF-T was significantly higher in females (p &lt; 0.05) at 5 years. The presence of dental calculus was the most prevalent periodontal condition at all ages. 91% of the children had a normal occlusion pattern. Acceptable standards of fluorosis were found in 91.4% between 15 and 19 years. Oral hygiene and use of fluoride paste were reported by 95%. Conclusion The mean DMFT at different ages is lower in the Guarani people than in the general population. The access to oral hygiene items and access to health services may explain some of these results. Epidemiological data is fundamental for planning future actions for this population.

title: Influence of the salt concentration on action mechanisms of natamycin against microorganisms of importance in food manufacture

description: Abstract The objective of this study was to evaluate the influence of salt concentration on action of natamycin on important microorganisms in food manufacturing as this preservative has been used in immersion baths in several dairy products in the country. Strains of Candida albicans, Escherichia coli and Staphylococcus aureus were inoculated at different saline and peptone water concentrations and received natamycin treatments. These solutions were maintained at 12 °C and the behavior of the microorganisms evaluated at 0, 24 and 48 hours (T0, T1 and T2). Each microorganism was assessed in isolation as well as the association of C. albicans and E. coli. Under the conditions proposed by the research, it was possible to conclude that 0.025% natamycin has no efficacy on C. albicans inoculated at saline concentrations below 5%. The results obtained in E. coli counts suggest that natamycin may interfere with its development even at concentrations that may be considered low (0.1%) and at salinity conditions of 7.5% to 10%. The association of natamycin with sodium chloride potentiates its antimicrobial action, which can represent an economy and its use is amplified by the industries.

title: Chromosome-level genome assembly of the brown alga Undaria pinnatifida using PacBio and Hi-C technologies

description: <i>Undaria pinnatifida</i> is an important economic kelp species in East Asia. In recent decades it has drawn increasing attention due to its worldwide spread as an invasive species. Lack of genome sequence hinders crucial fundamental researches in this alga. Herein, we present the whole genome sequence of a male gametophyte of <i>U. pinnatifida</i>, the first reference genome of the family Alariaceae. The genome, which was assembled based on the clean data produced by the Pacific Biosciences sequencing platform, was 511.0 Mb with contig N50 length of 1.7 Mb. We then assembled the contigs into chromosome-level scaffolds with an N50 length of 16.5 Mb using the high-throughput chromosome conformation capture (Hi-C) technology. In total 502.8 Mb genomic sequences were located on 30 chromosomes, accounting for 98.4% of the whole assembled length. A total of 12,402 protein-coding genes were annotated in the reference genome. This chromosome-level genome will provide valuable information for molecular biological studies in <i>U. pinnatifida</i> and comparative genomic studies with other brown algae.<br>

title: Efficient Regionalization for Spatially Explicit Neighborhood Delineation

description: # Efficient Regionalization for Spatially Explicit Neighborhood Delineation<br>## AbstractNeighborhood delineation is increasingly relied upon in urban social science research to identify the most appropriate spatial unit. In problems of this type, the true number of neighborhoods (typically called the k parameter) is unknown and analysts often require algorithmic approaches determine kendogenously. Existing approaches for neighborhood delineation that do not require pre-specification ofa k-parameter, however, are either nonspatial or lead to noncontiguous or overlapping regions. In this paper, we propose the use of max-p-regions for neighborhood delineation so that the geographic space can be partitioned into a set of homogeneous and geographically contiguous neighborhoods. In addition, we developed a new efficient algorithm to address the computational challenges associated with solving the max-p-regions so that it can be applied for large-scale neighborhood delineation. This new algorithm is implemented in the open-source Python Spatial Analysis Library (PySAL). Computational experiments based on both simulated and realistic data sets are performed and the results demonstrate its effectiveness and efficiency.<br>## Instructions<br><br>The files in this archive demonstrate the code for the new max-p algorithm.<br>To run the demonstration, please do the following:<br>1. extract the archive `unzip maxp.zip`2.
