Abstract Samanea tubulosa Benth. it has been widely used in traditional medicine to treat inflammatory processes. The present study aimed to investigate the antinociceptive effect and mechanism of action of the fractions obtained from the Samanea tubulosa pods in mice. The antinociceptive activity was evaluated in formalin, capsaicin and glutamate tests and the. The possible mechanisms of action involved in the antinociceptive effect of the hexane and ethyl acetate fraction in the opioid system, also the the K + ATP channels and the L-arigine pathways of nitric oxide were evaluated. The chemical characterization analysis revealed in the hexane fraction the presence of triterpenes such as lupenone and lupeol. In the glutamate test, the hexane and ethyl acetate fractions showed antinociceptive activity at the dose of 12.5 and 25 mg kg-1. The antinociception produced by the hexane and ethyl acetate fractions was significantly reversed by naloxone, indicating that the fractions act through the opioid pathway. Antinociceptive response of the ethyl acetate fraction was blocked by glibenclamide, indicating that this fraction acts via the K + ATP channels activation. It is concluded that the fractions under study exert antinociceptive activity possibly related to the opioid route and through K+ ATP channels activation.

ABSTRACT In the Amazon region, soil patches with an anthropic A horizon are found, called Indian black earths (IBEs). Indian black earths are highly fertile and, therefore, are deforested by small local farmers to cultivate without basic management that maintains soil and crop sustainability. Therefore, in order to evaluate the effect of using different cultures on the spatial variability of soil chemical attributes, three cultivated IBEs and one IBE under natural forest were selected for georeferencing and sample collection. The collection was made with a mesh system with 88 points per IBE, stratified in three layers: 0–0.05, 0.05–0.10 and 0.10–0.20 m. The soil was sampled, dried in the shade and sieved to obtain the fine earth fraction for analysis of chemical attributes. Descriptive statistical and geostatistical analyses were applied to the results. The use and management of soil influenced the spatial behavior of the chemical attributes of IBEs. The cultivation of Brachiaria over many years favored the reduction of the spatial variability of chemical attributes. The use of cacao and coffee crops also favored the homogeneity of the IBEs in relation to the natural forest, but not as much as for Brachiaria, likely due to the succession of crops that preceded these crops. The IBE in the forest contains a high natural spatial correlation in the first 0.1 m of the surface; however, more than 70% of this correlation is linked to a random variation.

Objetivou-se com este trabalho avaliar os efeitos de distintas salinidades da água de irrigação sobre o crescimento de porta-enxertos de goiabeira cv. Paluma adubada com doses crescentes de potássio, em experimento conduzido sob condições de estufa do CCTA/UFCG município de Pombal - PB. O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 5 x 4, cujos tratamentos resultaram da combinação de cinco níveis de condutividade elétrica da água de irrigação (CEa = 0,3; 1,1; 1,9; 2,7 e 3,5 dS m-1) e quatro doses de potássio (70, 100, 130 e 160% de K) sendo a dose referente a 100% de K correspondente a 726 mg de K dm-3 de substrato, com quatro repetições e duas plantas por parcela, sem bordadura. O aumento da salinidade da água de irrigação reduz o crescimento de porta-enxerto de goiabeira cv. Paluma, sendo os efeitos mais deletérios em níveis superiores a 1,9 dS m-1; doses crescentes de K até 1.161,6 mg de K dm-3 de substrato não atenuaram os efeitos nocivos dos sais, bem como, não exerceram diferença sobre o crescimento da maioria das variáveis de porta-enxerto de goiabeira cv. Paluma aos 120 e 225 dias após a emergência.

The objective of this work was to evaluate the effects of different irrigation water salinities on the growth of guava rootstock cv. Paluma fertilized with increasing doses of potassium, in an experiment conducted under greenhouse conditions of the CCTA / UFCG municipality of Pombal - PB. The experimental design was a randomized complete block design in a 5 x 4 factorial scheme, whose treatments resulted from the combination of five levels of electrical conductivity of the irrigation water (ECw = 0.3, 1.1, 1.9, 2.7 and 3.5 dS m-1) and four doses of potassium (70, 100, 130 and 160% K), the dose corresponding to 100% K corresponding to 726 mg K dm-3 substrate, with four replicates and two plants per plot, no border. The increase of salinity of the irrigation water reduces the growth of guava rootstock cv. Paluma, the most deleterious effects being at levels above 1.9 dS m-1; increasing doses of K up to 1161.6 mg K dm-3 substrate did not attenuate the harmful effects of the salts, nor did they exert any difference on the growth of most of the variables of guava rootstock cv. Paluma at 120 and 225 days after the emergency.

ABSTRACT The objective of this study was to regionalize 7-day 10-year low flows, long-term annual mean, and 90% and 95% permanence flows from Piquiri (PR) river basin. The following regionalization methods were adopted: Traditional, Linear interpolation, Chaves, Modified linear interpolation, and Modified Chaves. The equations obtained by the Traditional method, adding main river length or drainage density as independent variables, significantly improved R2 equations value. Streamflow forecasting by Linear Interpolation and Chaves methods were as good as those provided by the Traditional Method, thus, these methods could be applied to Piquiri River basin, especially when drainage area is the only available spatial information.

ABSTRACT This study aimed to compare methods for estimating reference evapotranspiration using an experimental basin in the Brazilian Cerrado, for water management purposes. For that, we estimated daily reference evapotranspiration over a certain period (time series between 1982 and 2012) through different empirical methods. These methods consisted of Blaney-Criddle (BC), Hargreaves & Samani (HS), ASCE Penman-Monteith (ASCE- PM), Penman (1948/1963) (PO), Priestley-Taylor (PT), which were all compared to the standard Penman-Monteith FAO-56 (PM-FAO56). Based on statistics, ASCE- PM, P and BC methods should be recommended for cerrado areas, either in rainy or dry seasons. After these, the PT also stood out. Among the less complex methods, based on temperature and energy data, PT method is recommended whether climatological data are scarce either in rainy or dry seasons. Yet, HS reached the greatest errors, a broad data spread and low estimate accuracy, but showing better performance in dry periods, thus remaining under restricted use.

ABSTRACT This study aimed to estimate the probability of climatological water deficit in an experimental watershed in the Cerrado biome, located in the central plateau of Brazil. For that, it was used a time series of 31 years (1982–2012). The probable climatological water deficit was calculated by the difference between rainfall and probable reference evapotranspiration, on a decennial scale. The reference evapotranspiration (ET0) was estimated by the standard FAO-56 Penman-Monteith method. To estimate water deficit, it was used gamma distribution, time series of rainfall and reference evapotranspiration. The adherence of the estimated probabilities to the observed data was verified by the Kolmogorov-Smirnov nonparametric test, with significance level (α-0.05), which presented a good adjustment to the distribution models. It was observed a climatological water deficit, in greater or lesser intensity, between the annual decennials 2 and 32.

O objetivo do trabalho foi avaliar a efici�ncia de um reator em batelada sequencial (RBS) na remo�ção biológica de nitrog�nio de efluente de abatedouro bovino, por meio dos processos de nitrifica�ção/desnitrifica�ção. Foram investigados os efeitos da concentra�ção inicial de nitrog�nio amoniacal de 100; 150 e 200 mg L-1 e vazção de ar de 0,125; 0,375 e 0,625 L min-1 Lreator-1 na remo�ção de compostos nitrogenados, por meio de configura�ção de um planejamento do tipo Delineamento Composto Central Rotacional (DCCR). Foram verificadas varia�›es de 9,2 a 94,9%, 4,0 a 19,6% e 20,8 a 92,0% na conversção de nitrog�nio amoniacal a nitrato, acœmulo de nitrito e remo�ção de nitrog�nio total, respectivamente. O aumento da vazção de ar e a diminui�ção da concentra�ção inicial de nitrog�nio amoniacal resultaram em maiores efici�ncias na remo�ção de nitrog�nio total e na conversção de nitrog�nio amoniacal a nitrato. Nos intervalos preestabelecidos do estudo, efici�ncias de remo�ção e conversção dos compostos nitrogenados, superiores a 85%, foram atingidas com varia�ção de vazção de ar de 0,375 a 0,725 L min-1 Lreator-1 e concentra�ção inicial de nitrog�nio amoniacal de 80 a 200 mg L-1. No processo de desnitrifica�ção, foram obtidas efici�ncias de 91,5 a 96,9% na remo�ção de nitrito/nitrato e de 78,3 a 87,9% na remo�ção de matŽria org‰nica.

The aim of this study was to evaluate the efficiency of a sequencing batch reactor (SBR) on biological removal of nitrogen from cattle slaughterhouse wastewater by nitrification/denitrification processes. The effects of initial concentration of ammoniacal nitrogen were investigated at 100; 150 and 200 mg L-1 and air flow rate at 0.125; 0.375 and 0.625 L min¹ Lreactor-1 on the nitrogen compounds removal, by a Central Composite Rotational Design (CCRD) configuration. There were variations from 9.2 to 94.9%, 4.0 to 19.6% and 20.8 to 92.0% in the conversion of ammoniacal nitrogen to nitrate and nitrite concentration and removal of total nitrogen, respectively. The increase of air flow rate and decrease of the initial concentration of ammoniacal nitrogen resulted in higher efficiencies of total nitrogen removal, as well as the conversion of ammoniacal nitrogen to nitrate. During the pre-established intervals of this study, the removal and conversion efficiencies of nitrogen compounds above 85% were achieved in air flow rate variations from 0.375 to 0.725 L min-1 Lreactor-1 and initial concentration of ammoniacal nitrogen from 80 to 200 mg L-1. On denitrification process, we obtained efficiencies from 91.5 to 96.9% on the removal of nitrite/nitrate and from 78.3 to 87.9% on the removal of organic matter.

Este trabalho teve por objetivo selecionar cepas de microrganismos com alto potencial de produção de lipase, a fim de remover óleos e graxas, no pré-tratamento da água residuária de purificação do biodiesel. Para tanto, foram feitas análises das características físico-químicas do efluente, e a partir desse resíduo foram isolados e selecionados microrganismos com potencial de produção de lipase. Em seguida, foi feito um ensaio de biodegradação de gordura, nas condições: pH (5,95), temperatura (35 ºC), rotação (180 rpm) e sulfato de amônio como fonte de nitrogênio (3 g L-1), e tendo como variáveis os microrganismos pré-selecionados e o tempo (24; 48; 72; 96 e 120 h). A água residuária de purificação do biodiesel apresentou uma concentração de O de 6,76 g L-1. Das seis culturas microbianas isoladas do tanque de decantação deste efluente, dois microrganismos (A e B) foram selecionados, com índice enzimático de 0,56 e 0,57, respectivamente. O tratamento da água residuária, utilizando o microrganismo isolado Klebsilla oxytoca, obteve uma remoção de O de 80% em 48 h.

O Programa Nacional de Produção e Uso do Biodiesel introduziu o biodiesel na matriz energética brasileira, trazendo a perspectiva de aumento da oferta de glicerina, coproduto gerado na proporção de 10 kg para cada 100 L de biodiesel. O objetivo principal deste trabalho foi avaliar a adição de glicerina bruta na digestão anaeróbia de efluente de indústria de fécula de mandioca (manipueira), em reator de fluxo semicontínuo horizontal de uma fase, em escala de laboratório. Foi utilizado um reator com volume útil de 8,77 L, meio suporte em eletroduto corrugado de policloreto de vinila (PVC), temperatura de 261 ºC, alimentado com manipueira e glicerina, aplicando-se tempos de detenção hidráulica de 4 e 5, dias e cargas orgânicas volumétricas crescentes de 3,05; 9,32; 14,83 e 13,59 g COD L-1 d-1, obtidas com a adição de glicerina aos níveis de 0; 2; 3 e 2% (v/v), respectivamente. As eficiências de remoção média de ST e STV foram decrescendo a partir da adição de glicerina à manipueira, com médias de 81,19 a 55,58 % para ST e 90,21 a 61,45% para STV. A adição de glicerina em 2% aumentou a produção de biogás em relação ao tratamento-controle, chegando a 1,979 L L-1 d-1. A produção de biogás em função da DQO consumida foi maior para o tratamento-controle que, para os tratamentos com adição de glicerina, indica menor conversão da matéria orgânica em biogás.

The Brazil's Biodiesel Production and Use Program introduces biodiesel in the Brazilian energy matrix, bringing along the perspective of a growth of the glycerin offer, co-product generated in the proportion of 10 kg for each 100 L of biodiesel. The aim of this study was to evaluate the addition of crude glycerin in the anaerobic digestion of cassava starch industry effluent (cassava wastewater), in a horizontal semi-continuous flow reactor of one phase in laboratory scale. It was used a reactor with a 8.77 L of useful volume, a medium support for corrugated conduit of polyvinyl chloride (PVC), temperature of 261 ºC, fed with cassava wastewater and glycerin, with hydraulic detention times of 4 and 5 days and increasing volumetric organic load of 3.05; 9.32; 14.83 and 13.59 g COD L-1 d-1, obtained with the addition of glycerin at 0; 2; 3 and 2% (v/v), respectively. The average removal efficiencies of TS and TVS were decreasing from the addition of glycerin to the cassava wastewater, averaging 81.19 to 55.58% for TS and 90.21 to 61.45% for TVS. The addition of glycerin at 2% increased the biogas production compared to the control treatment, reaching 1.979 L L-1 d-1. The biogas production as a function of the consumed COD was higher for the control treatment than for the treatments with addition of glycerin, which indicates lower conversion of organic matter into biogas.

Um reator em bateladas sequenciais com biomassa em suspensão e volume útil de 5L, aplicado para remoção de nutrientes e matéria orgânica, foi operado em escala de bancada, nas condições ótimas obtidas a partir de um delineamento composto central rotacional (DCCR), tempo de ciclo (TC) de 16 h (10h15 fase aeróbia e 4h35 fase anóxica) e relação carbono:nitrogênio (DQO/N-NO2-+N-NO3-) de 6. Avaliaram-se 20 ciclos completos, nitrificação seguida de desnitrificação, com o objetivo de efetuar o estudo do comportamento cinético de degradação da matéria orgânica (DQO) e nitrogenada (N-NH4+, N-NO2- e N-NO3-) presentes no efluente proveniente do abate e industrialização de aves, bem como avaliar a estabilidade do reator através de gráficos de controle Shewhart para medidas individuais. Os resultados apontaram valores médios de remoção de nitrogênio inorgânico total (N-NH4++N-NO2-+N-NO 3-) de 84,32±1,59% (C.V.=1,89%) e de matéria orgânica (DQO) de 53,65±8,48% (CV= 15,81%), no processo completo (nitrificação-desnitrificação), estando o processo sob controle estatístico. A atividade nitrificante estimada, durante a fase aeróbia, pela determinação dos parâmetros cinéticos, apresentou valores médios para K1 e K2, de 0,00381±0,00043 min-1 e 0,00249±0,00056 min-1, respectivamente. A avaliação do comportamento cinético de conversão do nitrogênio indicou possível redução no TC da fase anóxica, uma vez que foram alcançadas remoções de N-NO2- e N-NO3-, superiores a 90%, em apenas uma hora de desnitrificação.

A sequential batch reactor with suspended biomass and useful volume of 5 L was used in the removal of nutrients and organic matter in workbench scale under optimal conditions obtained by central composite rotational design (CCRD), with cycle time (CT) of 16 h (10.15 h, aerobic phase, and 4.35 h, anoxic phase) and carbon: nitrogen ratio (COD/NO2--N+NO3--N) equal to 6. Complete cycles (20), nitrification followed by denitrification, were evaluated to investigate the kinetic behavior of degradation of organic (COD) and nitrogenated (NH4+-N, NO2--N and NO3--N) matter present in the effluent from a bird slaughterhouse and industrial processing facility, as well as to evaluate the stability of the reactor using Shewhart control charts of individual measures. The results indicate means total inorganic nitrogen (NH4+-N+NO2- -N+NO3--N) removal of 84.32±1.59% and organic matter (COD) of 53.65±8.48% in the complete process (nitrification-denitrification) with the process under statistical control. The nitrifying activity during the aerobic phase estimated from the determination of the kinetic parameters had mean K1 and K2 values of 0.00381±0.00043 min-1 and 0.00381±0.00043 min-1, respectively. The evaluation of the kinetic behavior of the conversion of nitrogen indicated a possible reduction of CT in the anoxic phase, since removals of NO2--N and NO3--N higher than 90% were obtained with only 1 h of denitrification.

O conhecimento do comportamento hidrossedimentológico de uma bacia hidrográfica é fundamental para a adequada gestão e uso de seus recursos hídricos. Este trabalho teve o objetivo de verificar a viabilidade de se determinar indiretamente a curva-chave de sedimentos usando como alternativa um turbidímetro. O trabalho foi desenvolvido no Rio São Francisco Falso, situado no oeste do Paraná, na margem esquerda do lago de ITAIPU. O método direto foi realizado usando o molinete e amostrador de sedimentos em suspensão DH-48. O método indireto consistiu no uso de linígrafo e turbidímetro. A partir dos resultados obtidos, foi possível concluir que o método indireto usando um turbidímetro apresentou-se plenamente viável, pois encontrou-se modelo matemático do tipo potencial igual ao método direto. Determinou-se ainda que a descarga média de sedimentos em suspensão no Rio São Francisco Falso, no ano agrícola de 2006/2007, foi de 7,26 t dia-1.

Understanding hydrosedimental behavior of a watershed is essential for properly managing and using its hydric resources. The objective of this study was to verify the feasibility of the alternative procedure for the indirect determination of the sediment key curve using a turbidimeter. The research was carried out on the São Francisco Falso River, which is situated in the west of the state of Paraná on the left bank of ITAIPU reservoir. The direct method was applied using a DH-48 sediment suspended sampler. The indirect method consisted of the use of a linigraph and a turbidimeter. Based on the results obtained, it was concluded that the indirect method using a turbidimeter showed to be fully feasible, since it gave a power function-type mathematical model equal of the direct method. Furthermore, the average suspended sediment discharge into the São Francisco Falso River during the 2006/2007 harvest was calculated at 7.26 metric t day-1.

Neste trabalho se avaliou a distribuição "in situ" de fósforo (P), matéria orgânica (MO), potássio (K), cálcio (Ca), magnésio (Mg), capacidade de troca catiônica (T), alumínio (Al), soma de bases (S), saturação por bases (V) e do pH, em um solo cultivado com soja irrigada com água residuária proveniente da suinocultura (ARS), com níveis de concentração de 0, 25, 50 e 75%. Constituiu-se um esquema fatorial a partir dos quatros níveis de concentração da ARS, das profundidades de 20, 40 e 60 cm com cinco repetições. Os resultados encontrados demonstraram diferenças significativas apenas para P, K e T no perfil do solo. Para todas as características na profundidade de 60 cm, os respectivos níveis de concentração estiveram bastante próximos aos níveis iniciais, ou seja, antes da aplicação dos tratamentos.

In this work the distribution was evaluated "in situ" of phosphorus (P), organic matter (MO), potassium (K), calcium (Ca), magnesium (Mg), cation exchange capacity (CEC), aluminum (Al), sum of bases (S), base saturation (V) and pH of a soil cultivated with soybean and irrigated with swine wastewater in the 0, 25, 50 and 75% levels.
