title: Evaluation of subway systems in CO 2 emissions: Comparative analysis of emissions from cars, buses and subways

description: ABSTRACT The transportation sector is responsible for a portion of the global emissions of carbon dioxide (CO2). Scientific studies published on CO2 emissions by passenger transport systems treat basically results involving only the emissions related to fuel consumption of cars and buses. As for subways, usually emissions related to the generation of electrical energy needed to provide the traction force of the trains are considered. No specific or standardized publications on other approaches to calculate emissions for subways were identified. Thus, this study aims to provide a scientific contribution to the general study of CO2 emissions by subways, conceptually defining five approaches of calculations and conducting a comparative analysis of CO2 emissions by cars, buses and subways. The result of this research allowed to quantify the actual contribution of subways on the reduction of total emissions from the transportation sector. In the traction power of trains approach, it was concluded that the subways of São Paulo and Rio de Janeiro emit 63.5 times less than cars and 8 times less than buses.

title: Alternative Communication Program for a Child with Cerebral Palsy and His Communication Partners: a Multiple-Probe Design Study

description: ABSTRACT Augmentative and Alternative Communication (AAC) for children with cerebral palsy is essential for their engagement in different contexts. Therefore, the purpose of this paper was to verify the effects of a program of AAC for a non-verbal child with cerebral palsy in three different contexts of daily life: school, home and rehabilitation settings. This study used a Multiple-probe Experimental Design. The participants were a child with cerebral palsy and three communication partners in their respective settings: teacher, mother and occupational therapist. The intervention consisted of the individualized process of theoretical and practical training directed at the communication partners and implementation of the AAC. After implementation of the intervention program, the results showed that the child and the communication partners successfully used AAC resources. The results indicate that the strategies adopted in the three contexts were effective and provided to the child and his communication partners an understanding of how to use the AAC effectively.

title: Rediscovering a forgotten scientific collection in the Rio Grande do Norte State, Brazil: The herpetological collection of the zoologist José Santiago Lima-Verde

description: Abstract: The zoologist Dr. José Santiago Lima-Verde (1945-2019) made a number of major contributions to the field of animal biology in the northeastern Brazil, in particular through his research with snakes. While employed as a professor at Escola Superior de Agricultura de Mossoró, currently the Universidade Federal Rural do Semi-Árido, Prof. Lima-Verde established a herpetological collection which remained forgotten for a number of decades. In the present study, we describe the revitalization of this collection, which included the updating of the identification of the species and the compilation of the metadata on the collection, which is now named the Coleção Herpetológica Lima-Verde. We catalogued 80 specimens representing 30 species, including 23 species of snakes, five lizards, and two amphisbaenians. One third (30%) of the specimens had information on dates and sites, with the majority of these specimens being collected in the Brazilian State of Rio Grande do Norte during the 1970's. We also catalogued 315 eggs of seven snake species, from 22 clutches laid in captivity. The collection presents unpublished data and will constitute a reference for future herpetological research on the species found in western region of State of Rio Grande do Norte. Our findings reinforce the importance of zoological collections for the understanding of patterns of biodiversity, and we would recommend the creation of more regional scientific collections and the broader recognition of their value as a basic source of biological data.

title: Single-Walled Carbon Nanotubes/Poly Vinyl Chloride Nanocomposites and its Properties

description: ABSTRACT The SWNTs was purified/functionalized by acid treatment method and the F-SWNTs were used as reinforcing materials. The acid treatment introduced carboxyl (–COOH) group to the SWNTs. The PVC and F-SWNTs/PVC films were prepared by solution casting method. The fractured surfaces of sample was analyzed through SEM and showed the dispersion of F-SWNTs in PVC. The thermal study indicated that the thermal stability of PVC is enhanced with F-SWNTs incorporation. The mechanical properties were also increased with CNTs filling. The solvent uptake study suggested that the nanocomposites resist towards solvent uptake, which is due to the hydrophobic nature of CNTs and their irregular network formation within the polymer matrix.

title: Use of eggshell as an alternative source of calcium to obtain calcium titanate (CaTiO3)

description: ABSTRACT We describe the study of the re-utilization of egg shell as an alternative mineral source of calcite in the synthesis of calcium titanate (CaTiO3). The raw materials were characterized by X-ray diffraction and X-ray fluorescence; compositions were formulated and sintered under different conditions. After sintering the crystalline phases formed were quantified by the Rietvield (MR) method, analyzes of apparent density (DA), impedance spectroscopy (EIA) and scanning electron microscopy (SEM) were performed. The results reveal the possibility of using the egg shell residue as a source of calcium for the formation of calcium titanate with perovskite structure, it is fundamental to consider studies of technical and economic viability are also developed so that possible applications of interest are feasible.

title: Conceptual Elaboration Through the Collaborative and Collective Creation of Digital Games in the Perspective of Inclusive Education

description: ABSTRACT: This paper examines the development of concepts in children with and without disabilities through digital game creation activities. The study presents the use of technology in a pedagogical approach based on Vygotsky's theories related to conceptual elaboration, imagination, and creativity in childhood and on advanced studies in game design with children. The qualitative research adopted the Design-Based Research (DBR) as a methodological approach, which made the collaborative and collective performance of students in games creation activities possible. The interdisciplinary team was composed by researchers and undergraduate students in the areas of computing, education, and design and by four children from the third year of Elementary Education at a school in Itajaí, Santa Catarina, including two with intellectual disabilities. Data analysis revealed the children's appropriation of concepts about digital games and their components, the perception of the game creation process, the complexity inherent in the construction of technologies, and the critical view of children regarding games and their use. Intellectual differences among children were overcome through approaches that favored their different competencies, which afforded admiration among peers, mutual respect, and school inclusion.

title: Simulation of climatic impacts of desertification in Northeast Brazil

description: ABSTRACT The climatic behavior of the Brazilian Northeast (BNE) was simulated considering a scenario where all its caatinga area was replaced by desert. Precipitation decreased in the region in almost every month of the year, mainly on the caatinga sector. Evapotranspiration showed decreases of great magnitude throughout the year, especially during the rainy season. Runoff presented overall increases, indicating a decrease of the water extracted by plant roots. Air temperature was the most affected variable, with increases of up to 6°C in some regions and an average increase of approximately 3°C in the caatinga area. In addition, there was a restorative mechanism associated with convergence of humidity that worked favoring precipitation although insufficient to prevent its reduction in the BNE.

title: Characterization of Lactobacillus plantarum strains isolated from Turkish pastırma and possibility to use of food industry

description: Abstract Five Lactobacillus plantarum strains (which were previously isolated from Turkish pastırma), were evaluated for the possibilities of using in the food industry. Antimicrobial properties, metabolic activities, exopolysaccharide production and antibiotic resistance were investigated. It was also assessed probiotics features such as adhesion ability, survival in simulated gastric environment and acid tolerance analysis. Antimicrobial activity was characterized based on effects of several enzymes, different temperature and pH. All strains showed remarkable antimicrobial activity and antimicrobial substances were found resistant to enzymes, high temperature and low pH. Metabolic activities and exopolysaccharide production of the strains were found relatively weak. Determinate to antibiotic susceptibility patterns 14 different antibiotics used and strains were found reliable in terms of transferable resistance genes except for erythromycin. All strains showed resistance to acidic condition and gastric environment. However, adhesion ability of strains was found relatively low. All findings showed that, these strains potential candidate for use in food industry especially as natural food preservatives because of antimicrobial activity capacity and one strain (S2) have remarkable potential to use as starter cultures or probiotics.

title: Elaboration and validation of a measure to evaluate the knowledge of primary care physicians in Brazil about nutritional recommendation for hypertension control

description: Abstract Background Primary health care physicians play a leading role in nutritional counseling to reduce hypertension related to morbidity and mortality. The literature is scarce on instruments validated for Brazil that evaluate the evidence based on knowledge of these professionals. Objective To elaborate a measure to evaluate the level of knowledge about nutritional recommendation for the control of hypertension for primary care physicians in Brazil. Method A validated instrument for the English language was used as the basis for the questionnaire elaboration, which was tested according to the fundamentals of the Item Response Theory. The dimensionality of the questionnaire was performed on the polychoric correlation matrix. For the estimation of the parameters of the items, the two Parameters Logistic Model (discrimination and difficulty) was used. Results Most of the items were considered easy, the discriminative power varied between high, moderate and low values. The absence of difficult items contributed to the imprecision of the measure among those with higher levels of knowledge. Conclusion The results show a measure that accurately measures physicians with a low level of knowledge, being a useful tool to identify professionals who need to improve their nutritional knowledge.

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.
