title: Cognitive neuroscience in the classroom: teaching strategies in Spanish Language

description: Abstract: In this article, we present an analysis of the activities of a didactic material developed for teaching reading in Spanish (PINHO, 2015b), based on concepts of Cognitive Neuroscience (COSENZA; GUERRA, 2011) and reading teaching and learning (LEFFA, 1996; SCHLATTER, 2009). The objective of this paper is to analyze some activities and strategies of teaching Spanish Language used in classes applied by the researcher in the mentioned research and to observe how they contribute with the teaching and learning of reading in Spanish language. The analysis of the activities was based on the neuroscientific concepts of cognitive functions (perception, memory, executive functions and expressive functions) and on studies about the development of reading ability. It was possible to verify that the activities of reading comprehension analyzed seek to develop cognitive functions during the process of learning to read in Spanish, besides to stimulating the use of reading strategies.

title: CHARACTERIZATION AND PHENOTYPIC VARIABILITY IN NATURAL POPULATIONS OF MANGABEIRA IN THE STATE OF TOCANTINS, BRAZIL

description: ABSTRACT This study aimed to characterize three natural populations of mangabeira (Hancornia speciosa) located in parts of the Cerrado in the region of Porto Nacional, State of Tocantins, as well as to evaluate phenotypic variability in individual plants based on the physicochemical properties of their fruits. Ten genotypes were selected from each population, and 20 fruits of each genotype were collected for analysis. Fruits were analyzed for transverse and longitudinal diameters, total mass, pulp mass and yield, and number and fresh mass of seeds. Two seeds were taken from each fruit for the measurement of longitudinal and transverse diameter and thickness. Furthermore, pH and soluble solids were measured in the total pulp of each genotype. Descriptive statistics were performed on the data from morphological characterization, and populations were compared by the Kruskal-Wallis test, followed by Dunn's test at 5% probability level. The relationship between variables was estimated by the Spearman’s correlation coefficient. Phenotypic variability was verified using the principal component analysis. All three natural populations of mangabeira investigated here exhibited similar characteristics regarding fruit morphology and pH. Significant differences were detected only in the transverse diameter of the seed (Canaã had the highest value) and for total soluble solids content (Providência had the highest value). Significant correlations were found for corresponding morphological variables and pH in each population, except for several negative correlations that were observed in the Canaã population, which produced more homogeneous fruit. The Providência population presented the largest and most massive fruit. The greatest phenotypic variabilities were observed in the São Judas Tadeu and Providência populations.

title: Serum testosterone does not affect bone mineral density in postmenopausal women

description: Objective The purpose of the present study was to investigate the correlation between serum testosterone levels and bone mineral density (BMD) in postmenopausal women.Materials and methods The study group was made up of postmenopausal women admitted to our tertiary center. Serum calcium, phosphorus, albumin, parathyroid hormone (PTH), thyrotropin (TSH), 25-OH vitamin D, and total testosterone concentrations were measured. Subjects were categorized into three groups regarding bone mineral density (BMD) values: normal (n = 22), osteopenia (n = 21), and osteoporosis (n = 21). Subjects were also categorized into three groups according to serum testosterone levels: low testosterone (n = 10), normal testosterone (n = 42), and high testosterone (n = 12).Results No significant difference was found for serum testosterone, TSH, calcium, phosphorus, albumin, PTH, and 25-hydroxyvitamin D levels among patients with normal BMD, osteopenia, and osteoporosis (p &gt; 0.05). Lumbar spine, total femur, femoral neck, trochanteric, intertrochanteric, and Ward’s triangle BMD values were similar for the different testosterone levels (p &gt; 0.05).Conclusion There was no correlation between serum testosterone levels and patient age, body-mass index, or any measured BMD values. Given the findings in our study, which failed to demonstrate a statistically significant relationship between testosterone and BMD, adjustment of other risk factors for osteoporosis might have a more distinctive effect in this setting.

title: Effect of the action of diamond burs with high speed on the tensile strength of cores cemented with zinc phosphate at different preparation times

description: Objective: To know the finishing effect, in order to be able to safely proceed with the cores preparation in the daily clinic, without compromising the prosthetic restoration longevity. Methods: This study used 48 human single-rooted premolars, which after the section of its crowns, were endodontically treated, and its root canal prepared 8 mm deep to receive cores casting in cobalt-chrome alloy. Cementing was made with zinc phosphate and the tensile test performed at different preparation times: G1 - without re-preparation after cementation (control); G2 - re-prepared 24 hours after cementation, and G3 - re-prepared 15 minutes after cementation. Results: Statistical analysis showed no significant difference in the tensile strength values in the different groups (p = 0.233), in other words, the core re-preparation 15 minutes or 24 hours after the cementation caused no significant reduction in tensile strength between the core and the root remaining when using the zinc phosphate cement. Conclusion: The metallic core re-preparation cast 15 minutes or 24 hours after cementation caused no significant reduction in tensile strength between the cast metallic core and the root remaining, although in absolute values there was an important difference.

title: Cervical cancer screening coverage in the state of Minas Gerais, Brazil between 2000-2010: a study using data from the Cervical Cancer Information System (SISCOLO)

description: Abstract This study aimed to analyze the cervical cancer screening in Minas Gerais, Brazil, regarding the number of tests performed annually and its coverage. We used data from the Cervical Cancer Information System (SISCOLO). Screenings performed between 2000 and 2010 were analyzed regards time sequence for women who lived in the state, aged 25-59 and users of the Unified Health System (SUS). We performed comparisons against target goals agreed for the Viva Mulher Program in the macroregions. The overall coverage was lower than the one set by Viva Mulher Program (63.8%) and also lower than the estimated by the population criteria (66.4%). In 2000, macroregions that showed the highest coverage for the two goals were: Northern Triangle, South and Central Triangle. In 2010, there were changes regarding the position occupied by the macroregions and coverage improvements. As for SUS targets, the Northern, Jequitinhonha and South macro-regions had the highest coverage. The differences between the two targets evaluated in this study highlight the importance of the criteria chosen for setting goals.

title: School Seen from Outside: what do the families say?

description: Abstract: The article aims at analyzing the view expressed in families' discourse regarding their children's school. Open answers from questionnaires filled in four municipal schools from Campinas, São Paulo state, elected by contrast criteria (higher or lower social-economic level) are analyzed. For this analysis, the topics of Education Quality; School-Community Relationship; School Organization; Reasons for School Appreciation; Extra-class Activities; and Security were considered. It is possible to observe a differential view towards school related to social class and that listening to the families allows for knowing the place occupied by the school in their lives, elucidating aspects which are not always clear to professionals that, when considered, can contribute to the students' school life.

title: ASSOCIATIONS BETWEEN ATTRIBUTES OF NITISOLS AND THE CLIMATE OF THE SOUTHERN COAST OF PERNAMBUCO

description: ABSTRACT Nitisols are livelihood sources of agricultural and socio-economic development in several underdeveloped countries worldwide, including Brazil. Brazilian Nitisols are usually associated with basaltic rocks found in the Southern and Southeastern regions of the country. However, Nitisols derived from basalt also occur on the southern coast of Pernambuco state, a region under full urban, agricultural, and industrial development. Aiming to understand the relationship between climate and attributes of Nitisols from the southern coast of Pernambuco, we performed morphological descriptions, physical and chemical analyzes, iron selective extraction, and soil mineralogy (sand, silt, and clay) for three basaltic soil profiles along a land slope. The results suggest a strong weathering of the profiles due to climate conditions, besides a great loss of basic cations and xanthization process, resulting in the natural genesis of acric Nitisols with yellowish coloration, which has not been yet cataloged for this soil order in the Brazilian taxonomic system. In addition, there is a variation for physical attributes of Nitisols along the slope.

title: Study of the electricity consumption reduction of a compressed air system: the case of a steelmaking company

description: Abstract This work aims to reduce the energy consumption and thus increase the availability of blast furnace compressors of a steelmaking company, located in Alto Paraopeba region in Minas Gerais state, Brazil, through the elimination of waste points in the compressed air distribution. In order to develop this work, an ultrasound test in the compressed air line was performed to identify and quantify leaks in the flow. Once the leaks were identified, they were eliminated through corrective maintenance and improvements, and then the energy consumption scenarios before and after the improvements were compared. As a result, the average monthly electricity consumption in the reporting period decreased by 57.2%. In addition, one compressor was set aside in stand-by condition, as in the original plant. Thus, one can prove the efficiency in eliminating of waste points in compressed air distribution, since the reduction of energy consumption is important for the company to remain competitive, as the cost of electric energy affects the final price of the final products.
