title: Partial Volume Prediction Through Nonlinear Mixed Modeling

description: ABSTRACT The objective of this study was to assess the prediction of partial volumes with nonlinear mixed modeling for Pinus taeda. The volume of 558 trees was measured. The four-parameter logistic model was used in its modified form for the nonlinear mixed approach and, for comparison, the 5th degree polynomial was used. In the mixed modeling, the random effects diameter, age and place were inserted. The statistical criteria used to assess the quality of the adjustment were the Akaike Information Criterion (AIC), the Bayesian Information Criterion (BIC), standard error of the estimate (Syx) and residual graphical analysis. Among the random effects analyzed, age obtained the best adjustment. However, to predict partial volumes, it was noticed that, regardless of the analyzed portion of the trunk, the 5th degree polynomial had the best estimates, with a mean standard error of 20.1% of the estimate compared to 51.8% of the logistic.

title: Pre-concentration potential evaluation for a silicate zinc ore by density and sensor-based sorting methods

description: Abstract Pre-concentration consists of the preliminary discarding of a fraction of the mineral processing plant feed which contains little or none of the mineral of interest, reducing the mass to be processed in downstream operations (e.g. milling, concentration and dewatering), as well as the capital and operational costs. In this context, this study investigates the performance of density and sensor-based sorting separation methods in the removal of carbonate gangue of a zinc ore, in size fractions typical of crusher products, using sink and float tests with heavy liquids, jig stratification and laboratory scale ore sorting tests using an X-Ray Transmission (XRT) sensor. The best results were obtained through sink and float in heavy liquids, which indicated the possibility of discarding 30% of the feed mass, removing over 60% of the carbonates (CaO and MgO) and losing only 2% of the zinc. The ore sorting tests also presented positive results, with approximately 93% of metallurgical recovery in 70% of the mass for both size fractions tested. The jig stratification results were worse, since the zinc content discarded with this method was high. The results indicate significant reduction potential for Capex and Opex costs using pre-concentration strategy.

title: Color stability of conventional and bulk fill composite resins

description: ABSTRACT Objective: This study compared the color stability of different dental composite resins after prolonged exposure to a coffee solution. Methods: Sixty-four cylindrical discs (10 mm diameter x 2 mm thickness) were prepared using 8 different dental composite resins (n=8, per group). The specimens were first immersed in artificial saliva for 24 h followed by immersion in a coffee solution for 14 days. The assessment of chromatic variation (ΔE) was performed with the aid of a Vita Easyshade Advanced spectrophotometer (VITA Zahnfabrik, Bad Sackingen, Germany). The color of each specimen was calculated based on the L*, a* and b* coordinates of the CIELab system. Results: Grandio SO had the lowest average chromatic variation (ΔE=7.77) after immersion in coffee solution. Durafill VS, Grandio and Z350 XT (ΔE=8.58; ΔE=9.52; ΔE=10.39, respectively) showed similar chromatic variation, with no statistical difference in relation to Grandio SO. However, the other dental composite resins evaluated showed statistically higher values of ΔE compared to Grandio SO, and Enamel HRi (ΔE=20.56) demonstrated the highest chromatic variation. Conclusion: The Bulk Fill and hybrid composite resins from the same manufacturer (Micerium, Avegno, Italy) showed greater chromatic variation than the other composite resins tested. Grandio SO (Voco, Cuxaven, Germany) had the lowest ΔE variation.

title: Behavior of Pulmonary Function after Hospital Discharge in Patients Submitted to Myocardial Revascularization

description: Abstract Background: Coronary artery bypass grafting (CABG) is a type of surgery where there is a compromise in one or more coronary arteries, with the objective of restoring function to the areas that have been compromised in the heart, possibly leading to respiratory compromise and postoperative complications. The return time of the pulmonary function to the preoperative condition is still indeterminate in the literature. Objective: To describe the behavior of pulmonary function after hospital discharge in patients submitted to CABG. Methods: This is a prospective cohort study. Only patients undergoing MRI, whose lung function was evaluated preoperatively, at hospital discharge and 30 days after surgery, were evaluated. This evaluation consisted of maximum inspiratory pressure (MIP) and expiratory (MEP), vital capacity (VC) and expiratory flow peak (EFP). Results: A total of 30 patients were evaluated, of which 18 (60%) were males, mean age 62 ± 9 years. A reduction in lung function from preoperative time to hospital discharge was observed in all variables. There was improvement in MIP (88 ± 9 vs 109 ± 5, p &lt; 0.001), MEP (67 ± 10 for 90 ± 8, p &lt; 0.001) and EFP (310 ± 59 for 390 ± 32, p &lt; 0.001), high for review. At the time of the review, no variables returned to their preoperative value: MIP (116 ± 5 for 109 ± 5, p = 0.43), MEP (111 ± 8 for 90 ± 8, p &lt; 0.001), VC (45 ± 12 for 39 ± 7, p = 0.33) and EFP (430 ± 40 for 390 ± 32, p &lt; 0.001). Conclusion: It is concluded that MRI surgery reduces lung function and is not reestablished after 30 days of the procedure. Being the expiratory muscular force and the peak of expiratory flow the most affected.

title: Alternative forced-molting methods in japanese quails

description: SUMMARY The aim of this study was to evaluate the effects of different forced-molting methods on the performance and quality of laying quail eggs. The experiment was conducted in a conventional shed for quails and lasted 115 days. 480 Japanese quails at an initial age of 52 weeks were used. The following treatments were evaluated: total feed fasting (control treatment); corn and soybean bran diet; high- zinc diet (7,300 ppm); wheat bran diet; and ground corn diet. A fully randomized experimental outline was used with 5 treatments and 4 repetitions. Each lot was formed by 24 quails with a total of 480 birds. Performance (production and egg weights, feed intake, feed conversion ratio per kg egg mass and per dozen eggs, viable eggs and egg viability) and egg quality (eggshell thickness and yield, specific weight and Haugh unit) were evaluated. Treatment differences were compared using the Scott-Knott test (5%). Wheat bran and high- zinc diets yielded poorer averages of egg production and feed conversion ratioper dozen eggs. Studied treatments had no influence on egg quality. Hence, we can conclude that corn- only or corn and soybean bran only feeds can be adopted as forced molting methods in Japanese quails instead of traditional fasting methods.

title: Normative evaluation of the actions of family health nurses in the control of schistosomiasis in Pernambuco

description: ABSTRACT Normative evaluation of nurse's actions in the control of schistosomiasis in Pernambuco within the Family Health Program was conducted between 2009 and 2011. A logic model has been built from the regulatory apparatus and a semi-structured questionnaire, which was applied to 40 nurses from 40 units of a random sample covering 23 municipalities. The actions were judged from the creation of the composite indicator Implementation Degree (GI). The management function (52.8%) was better implemented than the technical function (33.3%). The GI process was 47.84 points (incipient). There was failure in the identification of the environmental criteria of risk, in joint planning and surveillance.

title: Characterization of automotive shredder residues before and five years after landfill disposal

description: The paper illustrates the results of an extensive analytical characterization study of automotive shredder residues (ASR), also known as "fluff". The analyses concerned material fractions and their content, with special reference to heavy metals (e.g. Cd, Cr, Hg, Pb, Cu) and arsenic. Elution tests on the original materials were also conducted. Moreover, chemical concentrations of ASR samples after about five years' landfill residence was assessed, in order to verify possible changes resulting from both in-situ leaching and organic matter degradation phenomena. Results show that lead seems to be the most critical element in view of possible ASR acceptance in non-hazardous waste landfills because of its high concentration in raw waste and, especially, of its proven leachability characteristics.

title: Geology and petrography of Jauru Group, at region of Retiro Novo Farm, SW of Amazonian Craton: a Statherian accretionary prism evidence

description: ABSTRACT: The Alto Jauru Group, located in southwestern Amazonian Craton, region of Retiro Novo Farm, comprises biotite-muscovite-quartz schists, chlorite-biotite-muscovite schists, garnet-cordierite-biotite schist and staurolite-andalusite-biotite schist, associated with garnet-sillimanite-biotite gneiss, biotite gneiss, amphibolite and muscovite granite. The group shows evidence of being an accretionary prism dominated by sediments. Petrography and structural relationships indicate that it was affected by two deformational events, Dn and Dn+1, associated with Sn foliation (schistosity and gneissic banding) and Sn+1 (crenulation cleavage), and three metamorphic events (M1, M2 and M3): the first is contemporary with Sn in lower greenschist facies; M2 is associated with the second phase of Sn+1 under greenschist to amphibolite facies; the third thermal event of amphibolite facies resulted from intrusion of the Cabaçal tonalite. Determination obtained by U-Pb (SHRIMP) on zircon provided the age of 1819 ± 6.7 Ma for the crystallization biotite gneiss igneous protolith. From the tectonic point of view, the Alto Jauru Group corresponds to an accretionary prism formed in the Statherian.

title: Agrochemicals and their impacts on human and environmental health: a systematic review

description: ABSTRACT Currently, Brazil is the largest consumer of agrochemicals in the world. Several studies have proved the harm to human and environment health due to exposure to agrochemicals. A systematic review was carried out over the period 2011 to 2017 about this theme on scientific databases. A total of 116 studies were included that demonstrated the negative impact on human and environment health. It is essential to carry out studies on the effects of chronic and simultaneous exposure to various agrochemicals, in addition to studies on the links of structural determination of the use of poisons and their consequences.

title: Specific gravity of eggs of female broiler breeders in the yield of incubation and chick weight post-hatch

description: SUMMARY The objective of this work was to evaluate the effect of specific gravity of eggs from broiler breeders of different ages in the yield of incubation and the weight of post-hatch chicks. Were used 3.072 eggs from two batches of broiler breeders, Cobb - 500®. The eggs were distributed a completely randomized design in a 2x4 factorial design with two broiler breeder ages (53 and 64 weeks) and four different egg densities (1.070, 1.075, 1.080, 1.085), totaling eight treatments and four replications (with 96 eggs per experimental unit). The evaluated variables were the egg weight (g), the hatching rate (%), the fertility rate (%), the weight loss of eggs during the incubation period (%) and the ratio of the weight of the chicks/egg weight (%). The results were submitted to analysis of variance, being that the effect of density was assessed by polynomial regression and the age effect of breeders by F test at 5% probability. Weight losses of eggs, except for the densities of 1,075 and 1,085, from breeders with 53 and 64 weeks of age, respectively, were within the values recommended in the literature. The chick weight was proportional to the weight of the egg, representing on average 68% and no differences between age and density of broiler breeders. The age of the breeders exerted influence on the yield of incubation, and the best results (p&lt;0.05) obtained by eggs from breeders with 53 weeks of age.

title: Chelated minerals and two limestone particle sizes on production of layers in the second laying cycle

description: SUMMARY The aim of this experiment was to evaluate the performance, egg quality, and bone quality of commercial white-egg layer hens in the second production cycle fed diets containing organic and inorganic minerals and two limestone particle sizes. A total of 215 birds with an average weight of 1.527 ± 0.092 kg were distributed in a completely randomized design in a 2 × 2 factorial arrangement (two mineral sources and two limestone particle sizes) with six replicates. The following four treatments were tested: T1 = inorganic minerals + 100% fine limestone; T2 = inorganic minerals + 50% fine limestone + 50% coarse limestone; T3 = organic minerals + 100% fine limestone; and T4 = organic minerals+ 50% fine limestone + 50% coarse limestone. No significant interaction occurred between the studied factors for any variable. Egg production, egg mass, bone resistance and bone deformity were higher with organic supplementation. Eggshell weight, percentage of eggshell, and specific gravity were higher in the treatments with the fine+coarse limestone association. In conclusion, organic mineral supplementation improves the performance based on egg production and egg mass. The association between fine and larger-sized limestone improves the external quality of eggs. The use of organic minerals improves the bone quality of birds in the second production cycle.
