title: Sewage sludge compost in zoysia grass sod production

description: Abstract This study evaluated whether the use of composted sewage sludge in zoysia grass sod production can partially or completely substitute fertilization based on urea. The experiment was conducted on a sod farm located in Itapetininga, São Paulo State, Brazil. The experimental design was a complete randomized block design with five replications and experimental plots of 5 m2 in a 2x6 factorial scheme. The first factor was the method of application (single or split), and the second factor was composted sewage sludge fertilization and two controls (no fertilization and a standard dose of conventional fertilizer). The conventional fertilizer (urea) dose corresponds to 300 kg N ha-1 and the sewage compost doses correspond to 100, 200, 300, and 400 kg N ha-1. The experiment began with the liming of the total area at 60 days after the previous harvest of zoysia grass sod. Three methods were used to evaluate sod production: soil cover rate, green color intensity, and leaf analysis. At 212 days after the beginning of the experiment, the compost treatment of 30 Mg ha-1 (300 kg ha-1 of N), applied in a single dose, allowed for complete sod formation (100% soil cover rate).

title: Ametoctradin: a new fungicide for potato late blight control

description: ABSTRACT: Late blight (Phytophthora infestans ) is among the most important and destructive diseases in potato cultivation. Aiming to evaluate the efficacy of the new fungicide ametoctradin, mixed with dimethomorph and metiram, an experiment was carried out in commercial potato crops (Ágata cultivar) in Pilar do Sul, São Paulo state, Brazil, during the growing season in 2013. A randomized block design was used, with 4 replications, on plots of 15 m2. Applications were carried out using a backpack sprayer with a spray-bar under 3 bar of constant pressure. The application volume varied from 300 L to 600 L.ha-1 based on crop development. The variables evaluated were leaf severity (0 to 100%), area under the disease progress curve, and yield. Ametoctradin + dimethomorph (1.25 L.ha-1) provided significant control of late blight, exceeding benthiavalicarb + fluazinam, dimethomorph + metiram, dimethomorph + pyraclostrobin, cymoxanil + mancozeb, metalaxyl-M + mancozeb, ametoctradin + metiram, and pyraclostrobin + metiram, although similar to ametoctradin + dimethomorph (1.00 L.ha-1), fluopicolide + propamocarb, and fenamidone + propamocarb. Ametoctradin + metiram resulted in moderate control, which was always similar to the standard. Ametoctradin and its associations represent a new alternative for the management of potato late blight.

title: Multi-objective Optimization Method For Repeat Ground-track Orbit Design Considering the Orbit Injection Error

description: ABSTRACT: Considering the adverse effects of orbit injection error, a novel repeat ground-track orbit redesign approach is proposed to reduce the fuel consumption caused by the orbital maneuvering from the injection orbit to the nominal orbit. By introducing the performance indexes of revisiting accuracy and orbit injection maneuvering fuel consumption, the problem of repeat ground track orbit redesign considering the orbit injection error is transformed into a multi-objective optimization problem, which can be solved by multi-objective genetic algorithm. Finally, the numerical simulations show that the redesigned repeat ground-track orbits not only can meet the requirements of revisiting ground targets with high accuracy, but also can reduce the required fuel consumption significantly.

title: Is pomegranate peels infusion effective for disinfection of toothbrushes?

description: Abstract Introduction Methods of decontamination or sanitization of toothbrushes have been questioned. Objective This study assessed the effectiveness of pomegranate peels infusion as a disinfectant of toothbrushes against Streptococcus mutans. Material and method A sample of 16 schoolchildren aged between 7 and 9 years performed brushing 5 days/week, with a careful brushing once a day. After each day of brushing, the toothbrushes were washed and sprayed with one disinfectant solution. This procedure was repeated for 4 weeks using one of the different solutions per week: distilled water (G1; negative control), pomegranate (Punica granatum Linn) peels infusion (G2), 1% sodium hypochlorite (G3) and 0.12% chlorhexidine digluconate (G4). After the fifth day, toothbrushes were collected for laboratory analysis. Toothbrushes heads were subjected to agitation in saline dilution of 10–1, 10–2,10–3, and 25 μL of each dilution were seeded in mitis salivarius agar culture medium for S. mutans colony-forming unit (CFU) counting. One calibrated examiner (Kappa = 0.91) performed the CFU (mL–1 × 104) counts. Kruskal-Wallis and Dunn Multiple Comparison tests were used at a significance level of 5%. Result G1 presented the highest number of CFU (3.9 ± 8.4), followed by G2 (3.2 ± 4.0). No S. mutans growth was observed in G3 and G4. There was no statistically significant difference between G1 and G2 and between G3 and G4 (p&gt;0.05). Conclusion Pomegranate infusion was completely ineffective for the disinfection of toothbrushes against S. mutans when compared with 1% sodium hypochlorite and 0.12% chlorhexidine digluconate solutions.

title: Gallic Acid and Cyclosporine Mixture and their Effects on Cardiac Dysfunction Induced by Ischemia/Reperfusion and eNOS/iNOS Expression

description: Abstract Background: Although many researches have been conducted on either a certain antioxidant or mPTP individually, little attention has been drawn to the effects of co-administration of an antioxidant and mPTP inhibitor together on cardiac dysfunction after I/R injury. Objectives: This study aims at determining the effects of gallic acid (as Antioxidant) combined with cyclosporine A (CsA) (as mPTP inhibitor) on I/R induced cardiac and endothelial (role of NO) dysfunction. Methods: Male Wistar rats were pretreated with gallic acid (7.5, 15, or 30 mg.kg-1 body weight, daily) for a period of 10 days. Then, the heart was isolated and exposed to 30-minute ischemia and perfused by CsA (0.2 µM) 20 min during reperfusion period. Results: The data have shown that infarct size was decreased significantly by CsA and gallic acid alone (p &lt; 0.05, one way ANOVA followed by LSD test), however the combination of both drugs had more significant improving effects (p &lt; 0.001). The combination of these two drugs improved more significantly maximum rate of rise and fall of ventricular pressure (±dp.dt-1 max), rate pressure product (RPP), left ventricular developed pressure (LVDP), heart rate and coronary flow rather than applying each one alone (p &lt; 0.05, repeated measurement ANOVA followed by LSD test). Conclusions: In conclusion, benefiting from an antioxidant concomitant with an mPTP inhibitor could have more improving effects on the cardiac dysfunction induced by I/R injury.

title: Regeneration under the Canopies of Native Species in a Restoration Area

description: Abstract This study aimed at evaluating the potential of Inga vera (Ingá) and Enterolobium contortisiliquum (Timbaúva) as facilitating species and their species-specific interaction on the restoration of a degraded and protected area in Rio Grande do Sul, Brazil. We surveyed the natural regeneration occurred under the canopies of 50 I. vera and E. contortisiliquum individuals, considering tree and shrub species with heights ≥ 30 cm and collar diameter ≥ 0.3 cm and &lt; 10 cm. We found 756 individuals under I. vera and 166 individuals under E. contortisiliquum. The study revealed that, despite corresponding to 19% of the total species found, the exotic species comprises 43.6% under I. vera and 11% under E. contortisiliquum. The I. vera presented a more significant number of species and individuals under its canopies when compared to E. contortisiliquum and the reference area.

title: Correlation of Socioeconomic and Environmental Factors with Municipal oil Royalties and CFEM

description: ABSTRACT This study aimed to determine the correlation between environmental, economic and social variables with royalties collected in the main oil and mineral producing municipalities. The data used, disaggregated by city, between 2004 and 2010, were the municipalities’ total revenue, investments in sanitation and environmental management, the number of inhabitants per municipality and Index FIRJAM municipal development. The relationship between the variables was evaluated by the Principal Component Analysis. The results showed that the largest collection of royalties, whether oil or mining, does not directly affect greater social or environmental development. Results can be explained by the lack of a legal framework that conditions the application of funds raised to the concerned areas. Thus, we conclude that the possible environmental and social impacts of exploitation of these non-renewable resources are not being rewarded for royalties.

title: Tube Volumes and Fertilization Management in Acrocarpus fraxinifolius Seedlings

description: Abstract Acrocarpus fraxinifolius, known as Indian cedar, has little forestry development in Brazil. Thus, the objective of this study was to find the best relation between nutrition and container (tube) volume in seedlings of this species. The experiment was carried out in a 2 × 8 factorial scheme (2 containers and 8 fertilizers), with polypropylene tubes of 50 and 110 cm³ being tested, and the following fertilization treatments: one control, 4 increasing doses of osmocotee plus: 3, 5, 7, 9 kg per m³ of substrate, and fractionated mineral fertilizations with cover manure. It was possible to note that the tube with the highest volume (110 cm³) presented better results for the morphological characteristics. However, when analyzing the physiological variables, it is clear that the 50 cm³ tubes presented similar results to the largest volume tube when well fertilized. It is concluded that the indicated to form seedlings of the species is the combination of tubes of 50 cm³ with the fertilization or double of this recommendation.

title: Allometric Relations in Leaves of Erythroxylum pauferrense: Endemic Species of Alto-Montana Forest in the Northeast Region, Brazil

description: Abstract Studies of leaf surface are important for the ecophysiological context. We tested 12 allometric equations to estimate the leaf area of the endemic species Erythroxylum pauferrense Plowman, using different morphometric measurements (n = 600). The analysis of variance (p &lt; 0.001), determination coefficient (R2adj), standard error of estimates (Sxy), and graphical interpretation of the dispersion of errors were used to select the models. The residual bias was estimated through the confidence interval using t-Student distribution (p = 0.01). Simple linear equations (Ŷ = 0.0244 + 0.7204 × CxL) and power functions (Ŷ = 0.7279 × CxL0.9971) were validated from an independent sample of leaves, confirming their accuracy. The results are important to guide actions of conservation of the endemic species.

title: Deproteinization: an integrated-solution approach to increase efficiency in β-galactosidase production using cheese whey powder (CWP) solution

description: Abstract Whey is the liquid that results from the coagulation of milk during cheese manufacture. Cheese whey is also an important environmental pollution source. The present experiment sought to compare β-galactosidase (EC 3.2.1.23) production by Aspergillus oryzae from deproteinized and un-deproteinized CWP solutions. β-galactosidase was produced by submerged fermentation in deproteinized or un-deproteinized CWP solutions. To determine the activity of the enzyme, a reaction mixture containing cell-free extract and ortho-Nitrophenyl-β-galactoside (ONPG) was used. The results indicated that β-galactosidase induction was greater when using deproteinized CWP solution compared to the un-deproteinized CWP solution. These results may enable an alternative management of cheese whey, thereby decreasing its impact on the environment and producing value-added biomacromolecules.
