title: Abrasive effects of sediments on impellers of pumps used for catching raw water

description: ABSTRACT This study presents an analysis of the abrasive effects of sediments from the bed of the Acre River, Brazil, on the wear of three different ferrous materials employed in the manufacture of impellers of centrifuge pumps used to catch raw water. In order to evaluate the abrasive wear and specific wear coefficient (k) as a function of sediment concentration, tests were conducted in samples of SAE 8620 steel, nodular cast iron and gray cast iron by using a rotary-ball abrasion meter. These tests employed abrasive slurry with concentration of 1, 2, 3, 5 and 10 g L-1 of sediments in distilled water. The volume of worn material as a function of the relative velocity of water flow in relation to the impeller blades was mathematically estimated. The experimental results showed that: i) The semi-angular and semi-rounded shapes of the sediments from the Acre River produced evidence of micro-grooving and plastic deformation in the three metallic alloys; ii) SAE 8620 steel showed higher resistance to abrasive wear than samples of gray and nodular cast iron; iii) the increase in the volume of worn material due to increment in sediment concentration and the relative velocity of the mixture (water + sediment) to the rotor pads.

title: Quality of ‘Fuji Suprema’ apples influenced by long-term annual addition of phosphorus to the soil

description: ABSTRACT: Fertilization of apple orchards with phosphorus (P) has received less attention than with nitrogen and potassium. In Brazil, the information about apple response to soil P addition is meager. The objective of this study was to evaluate the long-term effect of annual soil P addition on quality and mineral composition of apple fruits. The experiment started in 2010, in a commercial orchard located in the São Joaquim, Southern of Brazil. The orchard consisted of ´Fuji Suprema’, planted in high-density on a Haplumbrept soil. Treatments consisted of 0, 40, 80, 120 and 160kg ha-1 P2O5 applied annually starting in 2010 broadcast over the soil surface along the tree row. Evaluations were performed from 2012/2013 through 2014/2015 growing seasons. We harvested three samples from each experimental unit. One sample was cold stored in a controlled atmosphere chamber for six months; the others were immediately evaluated for firmness, total soluble solids, titratable acidity (TA), skin color, and the concentrations of N, P, K, Ca and Mg in the fruit flesh. Application of P to the soil affected only flesh firmness at harvest and TA after six months of storage in the 2012/2013 season, as well as firmness after six months of storage in the 2013/2014 season. In the 2014/2015 season, the addition of P reduced fruit color but only at harvest. Addition of P to the soil affected the levels of P in the fruit in the 2012/2013 season, as well as N and the N/Ca ratio of fruit in the 2014/2015 season. Overall, attributes related to fruit quality of cultivar Fuji Suprema were slightly affected by long-term annual addition of P to the soil.

title: SOIL ATTRIBUTES AND WHEAT PERFORMANCE IN A GEOREFERENCED SEED PRODUCTION FIELD

description: ABSTRACT The aim of this research was to study the linear correlations and spatial distribution between soil attributes and productivity and physiological quality of wheat seeds. Soil samples were collected at georeferenced points in an area of 41 ha with a rectangular grid of 100 × 100 m to determine soil fertility. Grain productivity, number of ears m-2, protein content, and physiological seed quality were assessed. The results were submitted to Pearson's correlation analysis, descriptive statistics, and geostatistics. Phosphorus content presented a high spatial variability, with a coefficient of variation of 97.79%. Protein content, number of ears, and SMP index presented low values of coefficient of variation, indicating their low spatial variability. Physiological seed quality was not correlated with soil attributes. Wheat productivity showed a strong correlation between calcium and soil organic matter contents, as verified by analyzing the spatial distribution maps. The analysis of the spatial distribution maps of soil nutrients is a tool that can contribute to farmers’ decision making in the management of crop fertilization aiming at increasing productivity.

title: RETENTION CURVES AND AVAILABLE WATER CAPACITY IN LATOSOLS

description: ABSTRACT Water stored in the soil between field capacity and the permanent wilting point, is known as the available water capacity. Its availability to be effectively used by plants depends on the type of soil and its water retention characteristics. The aim of this work was to compile information about water retention curves in Latosols, and to provide a first approximation of values and most likely amplitudes for water storage and available water capacity of these soils. The database was constituted from information collected from articles, theses, dissertations and other publications. Soil water retention curves, as well as available water, were estimated for the order Latosols, and for the suborders Red Latosol (RL), Red-Yellow Latosol (RYL) and Yellow Latosol (YL). RL presented the lowest amplitude of water storage between field capacity and permanent wilting point, resulting in lower available water capacity compared to Yellow and Red-Yellow Latosols. YL presented the highest available water capacity among analyzed soils.

title: THE PHOTOVOLTAIC ELECTRIFICATION IN ISOLATED COMMUNITIES OF CARDOSO ISLAND STATE PARK - SP

description: ABSTRACT This study concerns a research conducted in 2014, in isolated communities of Cambriú and Foles belonging to the Cardoso Island State Park-SP, in order to establish a link between electrification through isolated photovoltaic systems type SIGIFI 30 (30 kWh/month) with the existing demands, interactions and changes in traditional communities studied. The energy in this case is presented as a structure component to these demands regarding to the labor, agriculture, fishing, health, education, comfort of buildings and income generation. The objective was to conduct an analysis of the implementation of photovoltaic electrification process, and to establish a relationship with the surveyed communities. The results demonstrated that electrification provided benefits to the residents of the communities, but it only achieves real success if linked to other public policy instruments such as health, education and transportation that considered the diversities and peculiarities of these populations with regard to the strong isolation to which they belong. It was also noted that the training or technical assistance provided was not characterized as causing problems for residents, that in the majority did not present significant complaints to the management and the operation of the installed systems.

title: Leprosy in individuals under the age of fifteen in priority cities, Mato Grosso, Brazil

description: ABSTRACT: Objectives: We aimed to compare the sociodemographic, clinical and epidemiological characteristics of individuals under the age of 15, reported to have leprosy, and who lived in priority and non-priority cities, as well as to compare the spatial distribution of these reported cases in such cities. This is a cross-sectional study of new leprosy cases in individuals under the age of 15 (n=429) registered in the Information System for Notifiable Diseases from the State of Mato Grosso, Brazil, between 2011 and 2013. The diagnosed cases were compared regarding sociodemographic, clinical and epidemiological aspects using the chi-square test at a 5% significance level. The spatial distribution was made through ArcGIS 10.2 software. Results: Of the 141 assessed cities in the state, according to the spatial distribution, 58.1% (n=82) showed a high, very high and hyper-endemic mean incidence coefficient, and, of these, 34.1% (n=28) include the group of priority municipalities. Of the new cases included in the study, 73.9% (n=317) were reported in priority cities. We observed a difference in the proportion of cases registered among the cities, with a greater proportion in priority cities, in the age group from five to nine years old (χ²=4.09; p=0.043), in the white race (χ²=7.01; p=0.008) and in the tuberculoid clinical form (χ²=3.89; p=0.048). There was a greater proportion in non-priority cases with regard to non-urban areas (χ²=24.23; p&lt;0.001), two to five skin lesions (χ²=5.93; p=0.014) and spontaneous demand (χ²=6.16; p=0.013). Conclusion: The differences highlighted regarding clinical and epidemiological characteristics between the cities demonstrate the difficulty of endemic control in both municipality groups.

title: Burden of tuberculosis trends in a Brazilian southern state

description: ABSTRACT: Introduction: The burden of tuberculosis has been scarcely explored in developing countries. Objective: To estimate the trend of the burden of tuberculosis in the state of Santa Catarina, southern Brazil, from 2007 to 2011. Methods: Epidemiological time-series study on tuberculosis notifications and deaths reported in the Disease Notification System and the Mortality Information System between 2007 and 2011. Crude rates of Disability-Adjusted Life Years (DALY) and subcomponents were calculated and standardized by gender and age groups. Segmented linear regression was used to estimate the trends for burden of tuberculosis during the study period. Results: There were 696 deaths and 8,598 notifications during the study period. The highest rate was found in 2009, with 91.8 DALY/100,000 inhabitants, and the lowest in 2007, with 67.2 DALY/100,000 inhabitants. The highest burden was among men in economically active age groups. The study showed a non-significant increase of 3.8% per year in DALY rates. Conclusion: The burden of tuberculosis remained stable in Santa Catarina, Brazil between 2007 and 2011.
