Abstract: stural control in children with typical development and children with profound hearing loss Original Research (1969) Total Article Views Authors: Monteiro de Sousa AM, de Fran a Barros J, Martins de Sousa Neto B Published Date May 2012 Volume 2012:5 Pages 433 - 439 DOI: http://dx.doi.org/10.2147/IJGM.S28693 Received: 30 November 2011 Accepted: 17 January 2012 Published: 09 May 2012 Aneliza Maria Monteiro de Sousa,1 J natas de Fran a Barros,2 Brígido Martins de Sousa Neto3 1Faculty of Health Sciences, University of Brasilia, Brasilia, Federal District, Brazil; 2Department of Physical Education at the Federal University of Rio Grande do Norte, Natal, Rio Grande do Norte, Brazil; 3University Center UNIEURO, Brasilia, Federal District, Brazil Purpose: To describe the behavior of the postural control in children with profound sensorineural hearing loss and compare the results of experimental tests with hearing children aged 7 to 10 years. Patients and methods: This is a cross-sectional study where 100 children were divided into experimental and control groups. We used a force platform, AccuSway Plus, where the tests were conducted under the experimental conditions: open base, eyes open (OBEO); open base, eyes closed (OBEC); closed base, eyes open (CBEO); closed base, eyes closed (CBEC). The body sway velocity (V) of the center of pressure, the displacement in the anteroposterior direction (COPap) and mediolateral (COPml) of the center of pressure were the parameters to evaluate the postural control. For statistical analysis we used the nonparametric Mann–Whitney U test, with a significance level of 5%. Results: In comparisons of variables between the groups, the experimental group outperformed by at least 75% of the control group values. In terms of global trends, the experimental group shows higher values of body oscillations in all experimental conditions and variables evaluated. Children with hearing loss had poorer balance performance compared to the group of hearing. The inferential analysis revealed a statistically significant difference in the balance between deaf and hearing children in the OBEC experimental condition in relation to the COPml parameter (P = 0.04). There were no statistically significant differences in comparisons between the sexes when the groups were analyzed separately. The prevalence of unknown etiology showed 58% of cases and congenital rubella in 16%. The discovery of deafness occurred in 70% of children before the age of 3 years. Conclusion: In this study, children with hearing loss had poorer balance performance compared to the group of hearing children. This finding confirms the need to investigate postural control through longitudinal studies to identify the area of sensory deficit causing poor balance performance and promote more specific early interventions.

Abstract: Soils of tropical forests are important to the global budgets of greenhouse gases. The Brazilian Atlantic Forest is the second largest tropical moist forest area of South America, after the vast Amazonian domain. This study aimed to investigate the emissions of Nitrous Oxide (N2O) and Carbon Dioxide (CO2) as well as methane (CH4) emissions and consumptions along an altitudinal transect and the relation between these fluxes and other climatic, edaphic and biological variables (temperature, fine roots, litterfall, and soil moisture). Annual means of N2O flux were 2.6 (±0.5), 0.9 (±0.1), and 0.7 (±0.2) ng N cm 2 h 1 at altitudes 100, 400, and 1000 m, respectively. On an annual basis, soils consumed CH4 at all altitudes with annual means of 1.0 (±0.2), 1.8 (±0.1), and 1.6 (±0.3) mg m 2 d 1 at 100 m, 400 m and 1000 m, respectively. Although not sampled in the hottest and wettest portion of the year because of instrument malfunctions, mean fluxes of CO2 averaged 3.6 (±0.2), 3.5 (±0.3), and 3.1 (±0.3) μmol m 2 s 1 at altitudes 100, 400 and 1000 m, respectively. N2O fluxes were significantly influenced by soil moisture and temperature. Soil-atmosphere exchange of methane responded to changes in soil moisture. Carbon dioxide emissions were strongly influenced by soil temperature. While the temperature gradient observed at our sites is only an imperfect proxy for climate warming, our results suggest that increasing temperatures will result in increased in microbial activity with a consequent increase in soil N2O and CO2 emissions and soil CH4 consumption.

Abstract: The objective of this work was to evaluate, by using path analysis, the influence of some agronomiccharacters on soybean yield. An experiment was conducted in cerrado soil, in Serra do Quilombo,Bom Jesus, Southern of Piaui State, from december 2007 to april 2008, in an Oxisol. The experimentaldesign was randomized blocks, with treatments consisting of six levels of phosphorus (0, 40, 60, 100,120 and 140 kg P2O5 ha-1) with four replications. Some characteristics were evaluated: plant height,height of first pod insertion, number of nodes per plant, number of string beans per plant, 100 grainsweight, dry weight and total grain production per plant. The number of pods per plant was the yieldcomponent that showed the greatest direct effect on dry matter and total grain production perplant. The number of nodes per plant had a strong indirect effect on dry matter production. Thevariable height of first pod insertion showed lower correlation with the other variables.

Abstract: To study the interactions between a Rhizobium tropici strain and lectins isolated from the seeds of Canavalia ensiformis (ConA) and Canavalia brasiliensis (ConBr), a lectin fluorescence assay was performed. In addition, an experiment was designed to evaluate the effect of the two lectins on bacterial growth. Both lectins were found to bind to R. tropici cells, but the interactions were inhibited by D-mannose. Interestingly, only ConBr stimulated bacterial growth in proportion to the concentrations used (15.6–500 μg/mL), and the bacterial growth stimulation was inhibited by D-mannose as well. Structure/Function analyses by bioinformatics were carried out to evaluate the volume and carbohydrate recognition domain (CRD) configuration of ConA and ConBr. The difference of spatial arrangement and volume of CRD may indicate the variation between biological activities of both lectins. The results suggest that ConBr could be a promising tool for studies focusing on the interactions between rhizobia and host plants.

Abstract: to use of waster water from desalting in the hydroponic cultivation, an experiment was carried out at the department of environmental science of the universidade federal rural do semi-árido-ufersa, in the municipal district of mossoró-rn, in pots with substrates of coconut fiber under greenhouse conditions. the experimental design was in randomized blocks, with three repetitions. treatments were composed of five levels of salinity of the nutrient solution obtained with, and without, dilution of the waster water from desalting (2.1, 3.6, 4.9, 6.0 and 7.0 ds m-1). the variables plant height, stem diameter, leaf area, mean weight of fruit and total and marketable yield were detemined. in general, the variables decreased linearly with the increase of the salinity of the nutrient solution, showing that the salinity with waster water from desalting reduces the absorption of water by the plants due to the osmotic effect.
