Abstract: Neste trabalho s o apresentados os resultados relativos à proposta para a amplia o do programa de coleta seletiva no município de S o Jorge do Ivaí, estado do Paraná, Brasil. A metodologia contempla aplica o de questionário, visita ao barrac o de triagem, caracteriza o gravimétrica de resíduos e confec o de mapa de zoneamento da coleta seletiva. A coleta seletiva atual foi implementada pela prefeitura municipal por meio de um projeto piloto na regi o central do município. Estima-se a coleta de 1,12 t mensal de resíduos com a participa o de 30% da popula o do município. No entanto, as estimativas aqui realizadas indicam a gera o diária de 6,0 t de resíduos sólidos urbanos com 20% (1,18 t diário) passíveis de reaproveitamento e reciclagem. Desse modo, se justifica a amplia o da coleta seletiva no município e as necessidades básicas para a realiza o dessa implanta o s o aqui descritas. = This paper presents the results for the proposed to expand the program of selective collection in the S o Jorge Ivaí, Paraná, Brazil. The methodology involved questionnaires, visits to the shed screening, characterization of wastes and gravimetric preparation of zoning map of the collection. The current selective collection was implemented by the municipal government through a pilot project in the central city. It is estimated to collect 1.12 tons per month of waste with theparticipation of 30% of the population of the municipality. However, the estimates made here indicate the daily generation of 6.0 tons of waste with 20% (1.18 t/day) capable of reusing and recycling. Thus, there is justification for expanding the collection at the county and the basic needs for the completion of this deployment are described here.

A New Independent GPS-Free System for Geo-Referencing from Space  [PDF]
P. Kaufmann, P. L. Kaufmann, S. V. D. Pamboukian, R. Vilhena de Moraes
Positioning (POS) , 2014, DOI: 10.4236/pos.2014.52005
Abstract: A new system’s geo-referencing from space is entirely free from any GNSS (GPS or equivalent) systems. The system addresses to various strategic and economic applications such as in remote clock synchronism, aircraft and balloon navigation, missile and smart bombs tracking, satellite orbital determination and remote target geo-positioning. The new geometry concept corresponds to an “inverted GPS” configuration, utilizing four ground-based reference stations, synchronized in time, installed at well known geodesic coordinates and a repeater in space, carried by an aircraft, balloon, satellite, etc. Signal transmitted by one of the reference bases is retransmitted by the transponder, received back by the four bases, producing four ranging measurements which are corrected for the time delays undergone in every retransmission. A minimization function was derived to compare the repeater’s positions referred to at least two groups of three reference bases, to correct for the signal transit time at the repeater and propagation delays, and consequently to provide the accurate repeater position for each time interaction. Once the repeater’s coordinates are known, the other determinations and applications become straightforward. The system solving algorithm and process performance has been demonstrated by simulations adopting a practical example with the transponder carried by an aircraft moving over bases and a target on the ground. Effects produced by reference clock synchronism uncertainties at the four bases on the measurements are reviewed.

Abstract: a method for arsenic determination in pharmaceutical grade baso4 by solid sampling electrothermal atomic absorption spectrometry (sos-et aas) is described. two background (bg) correction systems, deuterium and zeeman-effect (z), were evaluated. background was decreased by using hydrogen combined with pd. accurate and precise results were obtained using z-sos-et aas. relative standard deviation using z-sos-et aas was lower than 9.5%. limit of detection was 0.005 μg g-1 and characteristic mass was 25.4 pg. results were also compared with those obtained using the preparation method suggested by european pharmacopoeia for baso4 followed by determination using inductively coupled plasma optical emission spectrometry and inductively coupled plasma mass spectrometry. results were around 20% lower than results obtained using the proposed method. some advantages as simplicity, higher sample throughput were found when compared with the official method currently described in pharmacopoeia.

A Hierarchical Dynamic Beta Regression Model of School Performance in the Brazilian Mathematical Olympiads for Public Schools
Alexandra M. Schmidt,Caroline P. de Moraes,Helio S. Migon
Statistics , 2015,
Abstract: The Brazilian Mathematical Olympiads for Public Schools (OBMEP) is held every year since 2005. In the 2013 edition there were over 47,000 schools registered involving nearly 19.2 million students. The Brazilian public educational system is structured into three administrative levels: federal, state and municipal. Students participating in the OBMEP come from three educational levels, two in primary and one in secondary school. We aim at studying the performance of Brazilian public schools which have been taking part of the OBMEP from 2006 until 2013. We propose a standardization of the mean scores of schools per year and educational level which is modeled through a hierarchical dynamic beta regression model. Both the mean and precision of the beta distribution are modeled as a function of covariates whose effects evolve smoothly with time. Results show that, regardless of the educational level, federal schools have better performance than municipal or state schools. The mean performance of schools increases with the human development index (HDI) of the municipality the school is located in. Moreover, the difference in mean performance between federal and state or municipal schools tends to increase with the HDI. Schools with higher proportion of boys tend to have better mean performance in the second and third educational levels of OBMEP.
Chemical Screening of Urochloa humidicola: Methods for Characterizing Secondary Metabolites and Allelopathic Activity on Forage Legumes  [PDF]
R. C. Ribeiro, M. G. de Carvalho, M. de L. L. de Moraes, R. O. P. Rossiello, D. R. de Oliveira, R. M. Q. de Amorim, E. Barbieri Junior
American Journal of Plant Sciences (AJPS) , 2018, DOI: 10.4236/ajps.2018.96093
Abstract: The aim of this study was to identify the main classes of secondary metabolites present in the root and shoot crude extracts and fractions from the forage grass Urochloa humidicola (Rendle) Morrone & Zuloaga and to evaluate the allelopathic effect of these metabolites on forage legumes for intercropping. Phytochemical prospecting analyses, 1H NMR and capillary electrophoresis were performed on extracts of U. humidicola. Allelopathic activity was evaluated in germination of Stylosanthes, Macrotyloma axillare and Lactuca sativa L. (standard) in the presence of crude extracts, isolated saponins, flavonoids and trans-cinnamic acid. The metabolite classes present in the extracts could be determined by the combined use of the tested analytical techniques, but their use alone was usually not sufficient to chemically characterize the species. Capillary electrophoresis was effective in detecting phenolic compounds. Macrotyloma axillare was tolerant to crude extracts of U. humidicola. Saponins and trans-cinnamic acid, but not the flavonoids, reduced germination of the target plants.
