title: Ore resource estimation based on radial based functions - Case study on União Luiz and Morro do Carrapato Gold Deposits (Alta Floresta Gold Province)

description: Abstract Radial basis functions can be used as an alternative method for mineral resource estimation when ordinary kriging cannot be done because it is impossible to calculate an experimental variogram. Interpolation based on radial based functions is a method that is similar to ordinary kriging. In this context, this article presents the results of gold resource estimation and modeling of the União Luis and Morro do Carrapato gold deposits located in Alta Floresta Gold Province, Mato Grosso. Experimental variograms in the main direction (90-degree strike) resulted in a pure nugget effect, whereas in the orthogonal direction (180/85), they resulted in a structured variogram. However, the structured variogram for 180/85 is useless because three orthogonal variograms are needed to define the anisotropy ellipsoid for deriving a correlation model used in ordinary kriging. Thus, mineral resource estimation was done using multiquadric equations, a very popular radial based function kernel. The 3D model for gold grades showed a vertical distribution suggesting a structural conditioning for gold mineralization. The grade-tonnage curve with a simulated cutoff of 5.0 g/ton resulted in a gold mineral resource of 2.122 tons. Through the above, the gold estimation and multiquadric equation-based 3D model for the studied area can be considered effective in its objective to estimate ore resources from the available data.

title: Effect of sodium nitroprusside (SNP) on the germination ofSenna macranthera seeds (DC. ex Collad.) H. S. Irwin & Baneby under salt stress

description: Nitric oxide (NO) has been used as stimulating of the germination process for many species. However, there are few studies evaluating the effect of nitric oxide donor in the regulation of seed germination under salt stress, especially for native forest species. The objective was to evaluate the effects of SNP, an NO donor substance, on germination of Senna macranthera seeds under salt stress. The seeds were germinated at different osmotic potentials induced by NaCl solution (0.0, -0.1, -0.2, -0.3, -0.4 and -0.5 MPa). To evaluate the effect of the SNP, potentials -0.3 and -0,4 MPa were selected, applying SNP at different concentrations: 100, 200, 300 and 400 µM. Germination tests were conducted at 25 °C, with photoperiod of 8 hours. Percentage of radicle protrusion, radicle protrusion speed index, percentage of normal seedlings, shoots and roots length and dry matter were evaluated. Salt stress with NaCl is harmful to germination of S. macranthera seeds. SNP has the potential to recover germination under salt stress, especially in the concentration of 100 µM.

title: Mathematical models for estimating the parameters of ruminal degradation kinetics of protein concentrates

description: SUMMARY This studied aimed to evaluate the parameters of ruminal degradation kinetics of protein concentrates, soybean meal (SM) and cotton cake (CC).To estimate the in situ degradation parameters of DM and CP from coproducts were fitted 5different non-linear mathematical models: Exponencial, Van Milgen, Logístico, Gompertz and Richards. For in situ evaluation were used two cattle cannulated in the rumen. The samples were incubate dat 0, 2, 4, 6, 12, 16, 24, 36, 48 and 72 hours and in the incubation residues were determined DM and CP and their degradability. The DM degradability of SM were 86.35, 74.23, 65.50% and to CC were 53.44, 41.70 and 35.21% in passage rates of 0.02; 0.05 and 0.08.h-1, respectively. The SM and CC showed values for the CP soluble fraction of the 18.15, 34.77% and 79.76, 55.10% to insoluble potentially degradable fraction, respectively. According to the Akaike weights (Wi) the model of Richards has 95.45 and 49.64% of chance to be the most suitable model to characterize the in situ DM degradation of SM and CC. However, the Gompertz model has 63.86 and 66.49% chance to be the most suitable model to characterize the CP in situ degradation of SM and CC.

title: NT-ProBNP at Admission Versus NT-ProBNP at Discharge as a Prognostic Predictor in Acute Decompensated Heart Failure

description: Abstract Background: Patients admitted for decompensated heart failure (HF) receive intensive diuretic and vasodilator therapy in the first days. Normally, this is a successful approach that leads to HF compensation and hospital discharge. However, recurrences within the first week of discharge are common. Objective: to evaluate whether the main predictor of recurrent outcomes in patients with HF is the severity of decompensation at admission or patient's blood volume after clinical management. Methods: Prospective, cohort study of patients admitted between January 2013 and October 2014, with diagnosis of acute decompensated HF, who were followed-up for 60 days after discharge. Inclusion criterion was increased plasma NT-proBNP (&gt; 450 pg/mL for patients younger than 50 years or &gt; 900 pg/mL for patients older than 50 years). Primary outcome was the combination of cardiovascular death with rehospitalization for decompensated HF in 60 days. Results: Ninety patients were studied, with median NT-proBNP at admission of 3,947pg/mL (IQR: 2,370 - 7,000 pg/mL), and median NT-proBNP at discharge of 1,946pg/mL (IQR: 1,000 - 3,781 pg/mL). The incidence of combined outcome was 30% (12.2% of deaths and 20% of rehospitalization). The area under the ROC curve for NT-proBNP at admission and 60-day cardiovascular events was 0.49 (p = 0.89; 95% CI = 0.36 - 0.62). The area under the curve of NT-proBNP absolute variation for 60 day-events was 0.65 (p = 0.04; 95%CI = 0.51 - 0.79), and the area under the curve for NT-BNP at discharge was 0.69 (p = 0.03; 95%CI = 0.58 - 0.80). In the multivariate analysis, pre-discharge NT-proBNP was a predictor of the primary outcome, independently of the NT-proBNP at admission and other risk factors. Conclusion: Different from the severity of decompensation at hospitalization, blood volume after compensation of HF is associated with recurrent event. This finding suggests that, regardless of initial severity, therapy response during hospitalization is determinant of the risk of recurrent decompensation.

title: Pleistocene-Holocene sedimentation of Solimões-Amazon fluvial system between the tributaries Negro and Madeira, Central Amazon

description: ABSTRACT: In the scope of Solimões-Amazon fluvial system between the Negro and Madeira tributaries, three levels of Quaternary fluvial terraces overlie the Alter do Chão and Novo Remanso formations further than 100 km southward its current main channel. Smooth undulated topography presenting low drainages density formed by sparse secondary plain channels and rounded lakes characterizes these deposits. Internally, they show point bars morphology constituted by intercalated layers of mud (silt and clay) and sand forming an inclined heterolithic stratification. The asymmetric distribution of fluvial terraces allied to the records of old scroll-bars features and paleochannels in many extensions of the Solimões River suggests the predominance of a meander pattern between 240 to 6 kyears. On the other hand, the development of the current anabranching pattern took place in the last six kyears due to the Holocene sea-level rise, besides the action of neotectonics and rainforest establishment related to the increase of humidity in Amazonia.

title: ESTIMATING THE NEED FOR NITROGEN IN THE PRODUCTION OF GRAIN AND SILAGE

description: ABSTRACT: The modeling for agriculture is a mathematical tool that allows us to weigh the effects of factors, environmental or management on crop productivity. Therefore, the aim of this study was to evaluate the efficiency of mathematical models, in the estimation of the productivity of maize over the need for nitrogen fertilization. Estimates of nitrogen fertilization were performed to obtain the potential productivity and depleted grain yield and silage corn genotypes. The Model 1 was based on estimates obtained in the literature and Model 2 on estimates generated by the proposed alternative model, calibrated with data observed in the experiment. To evaluate the performance of the models we used statistical indicators, such as Pearson correlation coefficient, Willmott agreement index, the performance index of Camargo, percentage deviation and medium square error. Recommendations of nitrogen generated by the models for the potential productivity and depleted much grain as silage were higher compared with the recommendations of the culture ways. The AG30A91 genotype had a higher leaf area index, reflecting higher estimates of potential productivity and depleted grain and silage. The model 2 can be used to estimate the yield of grain and silage and the need for simulation of nitrogen for grain production, however, requires adjustments to estimate nitrogen needs for the production of silage. Both models are efficient in simulating the crop cycle.

title: Urban Tree Planting Analysis in Four Squares of Tijuca, Rio de Janeiro, Brazil

description: In the present study, we conducted a tree planting evaluation in four squares of Tijuca, Rio de Janeiro, where we analyzed the species richness, diameter at breast height (DBH) and height of subjects, and we also performed a diagnosis of plant health. We found 310 individuals, distributed in 36 species and 14 families, with more emphasis on Cassia siamea and Delonix regia (32.4%). Cassia siamea represented 9.4% of the subjects of Castilho France square, 32.3% of Varnhagen square, 24.0% of Saens Pena square and 11.1% of Xavier de Brito square. Delonix regia totaled 3.2% of the species of Varnhagen square, 10.7% of Saens Pena and 35.2% of Xavier de Brito. A proportional distribution between exotic and native species was observed in the four squares investigated; however, a predominance of exotic species was found when the number of subjects was compared. 83.6% of the subjects presented height between 5 and 15 m. It was possible to observe that 49.5% of the trees showed DBH greater than 30 cm. 64.5% of the trees are healthy, 25.4% are being attacked by pests, and 10.1% have suffered worrying injuries. Given these facts, we recommend the replacement of debilitated subjects that represent a threat to users or impair aesthetics, always trying to use the largest possible number of native species to avoid uniformity. It is also necessary to intensify the control of pests and environmental education activities in order to reduce damage to flora specimens of urban squares.

title: Effect of vitamins and sterol as foliar additives in the development of Bombyx mori L. and influence of the application mode

description: The present study was aimed to evaluate the effects of different methods of foliar application of the additives nandrolone decanoate (anabolic steroid) 0,5%; ascorbic acid (vitamin C) 0,5%; retinol palmitate (vitamin A) 0,5%; and retinol acetate (vitamin A) 1,0% on some biological parameters of the silkworm. The experiment of application method (foliar spray prior to delivery, after delivery and soaking before feeding) used: nandrolone decanoate 0.5%, ascorbic acid 0.5%, and retinol palmitate 0.5%. The test of insect development evaluated: duration and larval viability, weight of cocoon, cocooning rate, liquid silk content, adult longevity, number of eggs per female and rising up time. For the application of foliar additives, the following were determined: weight gain, length, diameter and abdomen diameter of fifth instar larvae, and length, diameter and weight of silk gland. The results showed that although ascorbic acid provided the best value for the development of the caterpillars body, it did not correspond to significant increase in production; retinol palmitate did not affect the larvae body development; retinol acetate and retinol palmitate prolong the larval period, without, however, significantly altering the production parameters. The immersion method of leaves before being delivered to the caterpillars is the most feasible for the foliar application of additives.

title: The Spanish Banks in face of the Corporate Social Responsibility Standards: previous analysis of the financial crisis

description: ABSTRACT Transparency of information in the field of CSR (Corporate Social Responsibility) is common to various standards. In recent years there has been a proliferation of standards and models for the formalization of CSR strategies. The objective is to assess the degree of implementation of standards of normalization. The analysis was conducted with data from the year 2008, coinciding with the first signs of the financial crisis, serving as a reference point to analyze the effect of the crisis. The field work was conducted using a survey answered by 57 Spanish credit institutions. We found a low degree of implementation of standards. The GRI (Global Reporting Initiative) and the ISO 14001 stood out. In view of the orientation of credit institutions towards the market, Banks have incorporated much more elaborated and comprehensive quality standards than other credit institutions, such as the implementation of the standard AS 1000 that is equivalent to the joint implementation of the ISO 14000 and 9000.
