Abstract:
Um experimento de campo foi executado, no período de mar o/2005 a fevereiro/2007, no município de Remígio, PB, para avaliar o efeito do biofertilizante supermagro (esterco fresco de bovino + água + macro e micro nutrientes), aplicado ao solo na forma líquida, sobre os teores de micronutrientes e sódio no solo. O trabalho consistiu na combina o de dois fatores: doses de supermagro, diluído em água na raz o de 1:4 (0, 1, 2, 3 e 4 L por planta), combinadas à aduba o de K2O (com e sem K2O), oriundo de cloreto de potássio, compondo um fatorial 5 x 2, no delineamento experimental em blocos casualizados, com três repeti es. A aplica o de supermagro, independentemente da adi o de K2O, promoveu aumento dos teores de boro, cobre, manganês e zinco, mas n o interferiu nos conteúdos de ferro e sódio no solo. A field experiment was carried out during the period from March/2005 to February/2007, in the municipality of Remígio, Paraíba State, Brazil, in order to evaluate the action of the “supermagro” biofertilizer (fresh bovine manure + water + macro and micronutrients) applied on the soil in liquid form, on the contents of soil micronutrients and sodium. The treatments were distributed in randomized blocks, with three repetitions, using the factorial design 5 x 2, consisting of levels of “supermagro” biofertilizer diluted in water in a 1:4 proportion (0, 1, 2, 3 and 4 L per plant), combined with K2O fertilization (with and without K2O), obtained from potassium chloride. The biofertilizer application on the soil in treatments without and with K2O, increased the contents of boron, copper, manganese and zinc on the soil, but had no effects on sodium and iron content.

Abstract:
an experiment was carried out during the period from december, 2005 to july, 2006, in municipality of remígio, paraíba, brazil, in order to evaluate the effects of the biofertilizer "supermagro" applied to soil in liquid form diluted in water in a ratio of 1:4, 30 days before and at intervals of 90 days after planting in absence and presence of potassium applied 60 days after planting and every 60 days subsequently until harvest on the production and mineral nutrition of yellow passion fruit plants (passiflora edulis f. flavicarpa deg.) the treatments were distributed in randomized blocks using the factorial design 5 x 2 referring to biofertilizer levels: 0, 1, 2, 3 and 4 l plant-1 in absence and presence of potassium at a k2o level of 20 g plant-1. the soil of the experimental area is a neossoil. the fruits were harvested daily for evaluation of fruit number per plant, mass of fruit, individual production per plant and productivity. the plants in the initial fructification phase were adequately provided with n, k, s, b, and zn, but they were deficient in p, ca, mg, cu, fe and mn. the mean mass of fruits was superior in plants of the treatments with biofertilizer and potassium, but the interaction biofertilizer "supermagro" versus potassium did not influence plant productivity.

Abstract:
alternative substrates, besides allowing the production of quality seedlings, reduce the production costs. in this work we evaluated the production of lettuce seedlings (lactuca sativa l.) using mixtures of carbonized rice husk and earthworm humus with different doses of sulpomag？. the experimental design consisted of complete randomized blocks, with five treatments and four replicates. the evaluated mixtures consisted of treatment 1: 70% of earthworm humus (hm) and 30% of carbonized rice husk (cac), with 12.2 g of arad phosphate (fa) per each liter of mixture, and treatments 2, 3 and 4: formulated with the same quantities of hm, cac and fa, added respectively with 2,0; 4,0 and 8,0 g of sulpomag？. the commercial substrate bioplant？ (sc) was used as control. the characteristics shoot fresh mass (mfpa), root fresh mass (mfrz), shoot dry matter (mspa), root dry matter (msrz), content of shoot dry matter (tmspa), content of root dry matter (tmsrz) and electrical conductivity (ce in ds m-1) were evaluated. the commercial substrate and the mixture 1 were superior to the others. independent of the doses of sulpomag？, the mixtures did not present differences among them. the mean values of the treatments for mspa were in the same tendency for mfpa, except for treatment 3, that presented production of mspa similar to treatment 1 and the commercial substrate. raising values of the electrical conductivity (ce) were observed in a linear way, in all mixtures, with increasing doses of sulpomag？. the production of lettuce seedlings is feasible similar to that obtained with the use of commercial substrate, using raw material found in the property. the production of mfpa was negatively affected by the addition of sulpomag？ in the substrate.

Abstract:
This paper presents a new approach for filter design based on stochastic distances and tests between distributions. A window is defined around each pixel, samples are compared and only those which pass a goodness-of-fit test are used to compute the filtered value. The technique is applied to intensity Synthetic Aperture Radar (SAR) data, using the Gamma model with varying number of looks allowing, thus, changes in heterogeneity. Modified Nagao-Matsuyama windows are used to define the samples. The proposal is compared with the Lee's filter which is considered a standard, using a protocol based on simulation. Among the criteria used to quantify the quality of filters, we employ the equivalent number of looks (related to the signal-to-noise ratio), line contrast, and edge preservation. Moreover, we also assessed the filters by the Universal Image Quality Index and the Pearson's correlation between edges.

Abstract:
In this paper, we provide some results related to the $\Delta_2$-condition of Musielak-Orlicz functions and $\varphi$-families of probability distributions, which are modeled on Musielak-Orlicz spaces. We show that if two $\varphi$-families are modeled on Musielak-Orlicz spaces generated by Musielak-Orlicz functions satisfying the $\Delta_{2}$-condition, then these $\varphi$-families are equal as sets. We also investigate the behavior of the normalizing function near the boundary of the set on which a $\varphi$-family is defined.

Abstract:
In this paper, we present a characterization of support functionals and smooth points in $L_{0}^{\Phi}$, the Musielak-Orlicz space equipped with the Orlicz norm. As a result, criterion for the smoothness of $L_{0}^{\Phi}$ is also obtained. Some expressions involving the norms of functionals in $(L_{0}^{\Phi})^{*}$, the topological dual of $L_{0}^{\Phi}$, are proved for arbitrary Musielak-Orlicz functions.

Abstract:
We generalize the exponential family of probability distributions. In our approach, the exponential function is replaced by a $\varphi$-function, resulting in a $\varphi$-family of probability distributions. We show how $\varphi$-families are constructed. In a $\varphi$-family, the analogue of the cumulant-generating function is a normalizing function. We define the $\varphi$-divergence as the Bregman divergence associated to the normalizing function, providing a generalization of the Kullback-Leibler divergence. A formula for the $\varphi$-divergence where the $\varphi$-function is the Kaniadakis' $\kappa$-exponential function is derived.

Abstract:
This paper presents a new approach for filter design based on stochastic distances and tests between distributions. A window is defined around each pixel, overlapping samples are compared and only those which pass a goodness-of-fit test are used to compute the filtered value. The technique is applied to intensity SAR data with homogeneous regions using the Gamma model. The proposal is compared with the Lee's filter using a protocol based on Monte Carlo. Among the criteria used to quantify the quality of filters, we employ the equivalent number of looks, line and edge preservation. Moreover, we also assessed the filters by the Universal Image Quality Index and the Pearson's correlation on edges regions.

Abstract:
In pregnant women subjected to spinal anesthesia for a Cesarean section, episodes of nausea and vomiting are common both during and following surgery. Acupuncture for the prophylaxis and treatment of these complications has been gaining in popularity due to its low cost, simplicity, absence of side effects and confirmed efficacy. This study investigated the efficacy of stimulating the P6 acupoint in conjunction with the use of dexamethasone as prophylaxis for nausea and vomiting in pregnant women submitted to spinal anesthesia for a Cesarean section. The patients (n = 100) were randomly distributed into two groups. In the first group (n = 50), a site located one centimeter laterally from P6 was stimulated. This is not a true acupuncture point (sham acupuncture). In the second group (n = 50), P6 was stimulated. In both groups, 4 mg of dexamethasone were administered intravenously. A questionnaire was used to obtain information on the occurrence of nausea and vomiting during surgery and in the first 12 hours postpartum. The chi-square test and Fisher’s exact test were used to assess differences between the groups. Age and physical status were similar in both groups. The incidence of nausea during surgery was 32% (n = 16) in the control group and 22% (n = 11) in the P6 group (p > 0.05). In the first 12 hours following surgery, nausea occurred in 16% of the women in the control group (n = 6) and in 4% in the P6 group (n = 4) (p = 0.045). The incidence of vomiting in the control group was 12% (n = 6) during surgery and 10% (n = 5) in the postoperative period compared to 8% (n = 4) and 4% (n = 2), respectively, in the P6 group (p > 0.05). Although these differences were not statistically significant with the exception of the incidence of nausea in the first 12 hours postpartum, a reduction occurred in the incidence of all the outcomes evaluated in the P6 group.

Abstract:
With the increased production of biodiesel, an excess of glycerol is being generated worldwide. One way to reduce the surplus of glycerol would be to use it as low calorific fuel in the own process of biodiesel production. However, being a high viscosity fuel with also high ignition point, its combustion requires severe control and monitoring due to the formation of the toxic pollutants. It is common practice mainly in developing countries to use biomass fuels in rural regions and it looks that with glycerol will not be different. The present article had as objective the construction of a simple chamber for the LPG assisted combustion of the biodiesel residual glycerol and the evaluation of all parameters related to the combustion itself. At a fixed mass flow of LPG different mass flows of glycerol were burnt and parameters such as O2, CO, CO , NOx, exhaust gases temperature, combustion efficiency and excess air were measured.
