title: EFFECT OF THERMO-MECHANICAL TREATMENT ON PROPERTIES OF PARICA PLYWOODS (Schizolobium amazonicum Huber ex Ducke)

description: ABSTRACT Thermo-mechanical treatment is a technique for wood modification in which samples are densified by means of heat and mechanical compression, applied perpendicularly to fibers, which under different combinations of time, temperature, and pressure increases wood density and thus improve some of its properties. This study aimed to treat thermo-mechanically parica plywood and observe the effects on its physical and mechanical properties. Specimens were submitted to two treatments, 120 and 150 ºC, remaining under pressure for seven minutes and, subsequently, under zero pressure for 15 minutes. Results showed a significant increase in specific mass from 0.48 g cm-3 to an average of 0.56 g cm-3, and a compression ratio of about 31.7% on average. Physical properties also varied significantly and results showed that treated samples swelled and absorbed more water than those untreated, leading to a greater thickness non-return rate. This indicates the proposed thermal treatments did not release the internal compressive stress generated during panel pressing, not improving its dimensional stability as a result. On the other hand, mechanical properties were positively affected, leading to an increase of 27.5% and 51.8% in modulus of rupture after treatments at 120 and 150 ºC, respectively. Modulus of elasticity and glue-line shear strength did not vary statistically and Janka hardness was 29.7% higher after treatment at 150 ºC.

title: National Conferences of Education: intellectuals, state and educational discourse (1927-1967)

description: ABSTRACT The article has as its object the educational discourse enunciated throughout the thirteen National Conferences of Education (CNEs), organized by the Brazilian Association of Education (ABE) and carried out between 1927 and 1967. In methodological terms, we have the conjectures of linguistic contextualism as a basis, in particular the notion of complex language. We will privilege the characterization of the ABE and its events, and the relations between the ABE and the State; we will also formulate a hypothesis about the structuring of educational discourse. The sources of the research are documents of a diverse nature, such as correspondences, newspapers, conferences and motions presented during the CNEs. In the study, we were able to identify the ABE and the CNEs as privileged places to project an intelligentsia with the authority to talk about the problems and, above all, about the goals and priorities of the national education. The study of the CNEs also revealed that the educational congresses fulfilled multiple functions, among which we highlight: giving visibility to the actions of the State; legitimizing the intellectuals involved in the direction of educational reforms; winning the consent of society in general and of the school community in particular for the implementation of intended changes; and, finally, structuring educational discourse.

title: Surveillance of intradomiciliary contacts of leprosy cases: perspective of the client in a hyperendemic municipality

description: ABSTRACT Objective: To characterize approach methods for intradomiciliary contacts (IdC) of leprosy cases resident in Northern Brazil, during 2001-2012. Method: A cross-sectional and descriptive study in the state of Rondônia. Included IdC of leprosy cases diagnosed/reported in SINAN-Ministry of Health (MS), 2001-2012. A semi-structured instrument was applied to the IdCs, with six interventions: complete dermatological examination; complete neurological examination; BCG vaccination; instructions for return to the health unit; BCG guidance; and guidance to mobilize other contacts. Results: From a total of 459 IdCs included, failure to perform the dermatological examination was reported by 191 people (41.6%) and the neurological examination, by 252 (54.9%); 138 (30.1%) did not have BCG indicated and 122 (26.6%) did not receive guidelines; 257 (56.0%) were not advised to return for a new evaluation/follow-up and 186 (40.5%) were not asked to mobilize other contacts. Conclusion: Despite the favorable indicators of IdC examination coverage in the state, the evaluation process presents patterns that indicate operational quality failures.

title: EFFECT OF PHOSPHATE FERTILIZATION AND BASE SATURATION OF SUBSTRATE ON THE SEEDLINGS GROWTH AND QUALITY OF Plathymenia foliolosa Benth.

description: ABSTRACT This study aimed to evaluate the growth and quality of seedlings of Plathymenia foliolosa Benth in response to base saturation of substrate and phosphate fertilization. The treatments were arranged in a factorial design of 6 P levels (0, 120, 240, 360, 480 and 600 mg dm-3) by 5 base saturation levels (3.5, 25, 40, 55, 70 %), in randomized blocks with four replications. The height of aerial part, neck diameter, shoot dry matter, root dry matter and total dry matter were determined at 118 days after the transplanting. It was still calculated the relation shoot dry matter/root dry matter and the Dickson Quality Index. There were significant effects of the phosphate fertilization for all studied variables. The base saturation had influence on all studied variables, except for the shoot dry matter/root dry matter relation. No significant effect of the interaction between base saturation of substrate and phosphate fertilization was observed on seedlings growth and quality. For the studied conditions, it is recommended 300 mg dm-3 of P for the production of quality seedlings of Plathymenia foliolosa without the necessity of liming.

title: Space-temporal analysis of Chagas disease and its environmental and demographic risk factors in the municipality of Barcarena, Pará, Brazil

description: ABSTRACT: Introduction: Chagas disease is a parasitosis considered a serious problem of public health. In the municipality of Barcarena, Pará, from 2007 to 2014, occurred the highest prevalence of this disease in Brazil. Objective: To analyze the disease distribution related to epidemiological, environmental and demographic variables, in the area and period of the study. Methods: Epidemiological and demographic data of Barcarena Health Department and satellite images from the National Institute For Space Research (INPE) were used. The deforestation data were obtained through satellite image classification, using artificial neural network. The statistical significance was done with the χ2 test, and the spatial dependence tests among the variables were done using Kernel and Moran techniques. Results: The epidemiological curve indicated a disease seasonal pattern. The major percentage of the cases were in male, brown skin color, adult, illiterate, urban areas and with probable oral contamination. It was confirmed the spatial dependence of the disease cases with the different types of deforestation identified in the municipality, as well as agglomerations of cases in urban and rural areas. Discussion: The disease distribution did not occur homogeneously, possibly due to the municipality demographic dynamics, with intense migratory flows that generates the deforestation. Conclusion: Different relationships among the variables studied and the occurrence of the disease in the municipality were observed. The technologies used were satisfactory to construct the disease epidemiological scenarios.

title: ASSESSMENT OF GENETIC STABILITY OF MICROPROPAGATED Eucalyptus globulus Labill HYBRID CLONES BY MEANS OF FLOW CYTOMETRY AND MICROSATELLITES MARKERS

description: ABSTRACT Flow cytometry and microsatellite markers were used to determine a genetic fidelity of micropropagated plants from the two Eucalyptus urophylla x E. globulus clones and a Eucalyptus grandis x E. globulus clone derived from adult material. Clones were repeatedly subcultured for 25 subcultures on MS medium supplemented with BA (2.22 µM) and ANA (0.05 µM) for in vitro shoot multiplication. The elongation was performed in MS culture medium supplemented with AIB (2.46 µM) and BA(0.22 µM). The ex vitro rooting and acclimatization phases were lead at the same time. The micropropagated clones showed genetic stability by flow cytometry and microsatellite markers. The results proved that micropropagation, for purposes of rejuvenation, can be a viable technique to generate genetically stable or identical E. globulus hybrid clones.

title: PHOSPHORUS FERTILIZATION AND HARVEST INTERVALS INFLUENCE ENERGETIC AND PHYSICAL PROPERTIES OF BRIQUETTES AND LARGE BRANCHES OF MATE

description: ABSTRACT In mate crop, the commercial part consists of leaves and thin branches, while the large branches (LB) are considered unused residues and left in the field, although they may have potential for use as energy. The objective of this paper was to evaluate the influence of phosphorus fertilization and harvest interval in productivity of mate large branches and in their physical and energetic properties, as well as in derived briquettes. In a seven-year-old plantation, doses of 0, 20, 40, 80, 160 and 320 kg.ha-1 of P2O5 were applied considering harvest intervals of 12, 18 and 24 months. Dry mass, average diameter, P content, and physical and energetic properties of LB were determined. With LB, after its transformation into particles and briquetting, physical and energetic properties were determined, as well as P availability in soil. The phosphorus fertilization increased LB productivity in larger harvest intervals, increasing the amount of energy produced per unit of area, but did not change basic density and gross calorific value of wood. Mate harvest intervals did not affect the apparent density and calorific value of briquettes produced by LB. LB harvested at intervals of 18 and 24 months produced wood with higher basic density and gross calorific value. LB or briquettes have adequate energetic and physical properties, being technically a plant residue with great potential for use as energy.

title: Burden of caregivers of children and adolescents with Down Syndrome

description: Abstract The aim of this study was to evaluate the profile and burden of caregivers of children/adolescents with and without Down syndrome. The evaluations were performed through questionnaires about the profile and burden of the caregivers (Zarit Burden Interview) and the profile of the children/adolescents. These questionnaires were applied to 168 caregivers. The chi-square test, Fisher's exact test, and analysis of variance were used with a significance level set at a = 5%. Both groups were composed of 84 participants, and the caregivers of the disabled group had a significantly higher percentage of females (p = 0.001), those in the 41-60 age group (p &lt; 0.001), those who had no occupation (p &lt; 0.001), those with a low per capita income (p &lt; 0.001), those with a low level of schooling (p = 0.021), those who were Catholic in religion (p = 0.001), those who had more health problems (p &lt; 0.001), those who continued the use of medication (p &lt; 0.001), and those with a moderate level of burden (p &lt; 0.001). The children/adolescents with disabilities needed significantly more help for eating (p = 0.051), bathing (p = 0.006), dressing (p = 0.042), sphincter control (p = 0.027), and intimate hygiene (p &lt; 0.001). The caregivers of children/adolescents with Down syndrome presented a moderate burden compared to the caregivers of normoreactive children/adolescents.
