title: Oral cancer in Brazil: a secular history of Public Health Policies

description: The oral cancer in Brazil is considered an important public health issue. Despite almost a century of combat disease, with oncological assistance programs and prevention campaigns based public policies, the incidence of oral cancer in several regions is still high. The major goal of cancer prevention and control is a reduction in both the incidence of the disease and the associated morbidity and mortality, as well as improved life for cancer patients and their families. Low-income and disadvantage groups are generally more exposed to avoidable risk factors such as tobacco and alcohol consumption. These groups have less access to the health services and education that would empower them to make decisions to protect and improve their own health. Thus, cancer control programs are the most effective instrument to bridge the gap between knowledge and practice and achieve this goal. The authors report some key historical facts concerning the fight against oral cancer in Brazil, in addition to addressing the epidemiological aspects of disease.

title: CUTTING HEIGHT AND ADDITION OF ENZYME-BACTERIAL INOCULANTS ON CORN SILAGE CHEMICAL COMPOSITION AND DIGESTIBILITY IN SHEEP

description: Abstract The objective of this experiment was to observe the influence of the height of corn plant cutting, associated or not with an enzyme-bacterial inoculant or not, on the chemical composition and digestibility of the silage in sheep. The cut heights were 20 and 40 centimeters above the soil. The additive inoculant was Maize-All®. We analyzed on silage: pH; dry matter; organic matter; crude protein; ether extract; neutral detergent fiber; acid detergent fiber; hemicellulose; cellulose; lignin; and non-fibrous carbohydrates. At the digestibility trial we evaluated apparent digestibility of DM, OM, CP, EE, NDF, ADF, Hem, Cel and NCF. We observed that a high cut reduced lignin value. The corn silage harvested at 20 cm had 84.0 g. kg-1 DM of lignin, higher value than the corn silage harvested at 40 cm (69.3 g. kg-1 MS), and there was no effect of inoculation. There were no differences among treatments at the digestibility trial. The cutting height reduced just lignin concentration. However, this lignin reduction did not affect digestibility and hence it did not affect the TDN concentration.

title: ACIDIFIER AND NUTRIENTS DIGESTIBILITY IN GROWING PIGS

description: Abstract The aim of the experiment was to evaluate the effect of the addition of acidifiers to diets on the digestibility of growing pigs. We used 18 pigs with an average initial weight of 53.55 kg. The treatments consisted of conventional diet (corn and soybean meal) and alternative diet (pre-cooked corn and inactive soybean), with the addition of an acidifier at the levels of 0%, 0.1%, and 0.2%. The experimental design was in randomized blocks in a 2 x 3 factorial arrangement (diets x levels of the acidifier). The alternative diet was worse for CP (P&lt;0.03) and ash (P&lt;0.001) digestibility, but improved fiber digestibility (CF, P &lt;0.001; ADF, P &lt;0.001). The addition of the acidifier (0.2%) improved digestibility of Ca (P &lt;0.01). There was an interaction between the acidifier and diet on digestibility coefficients of DM (P &lt;0.01) and NDF (P&lt;0.02). The alternative diet showed higher DM digestibility than the conventional diet when added 0.1% acidifier, respectively, 86.02% and 84.51% (P&lt;0.05). As for NDF digestibility results, the alternative diet showed higher values than the conventional diet with the addition of 0% or 0.1% of the acidifier. For the alternative diet with 0.2%, values greater than 0 or 0.1% (P&lt;0.05) were obtained.

title: REQUIREMENT OF METHIONINE PLUS CYSTINE FOR PULLETS IN THE INITIAL PHASE (1 TO 6 WEEKS OLD)

description: Abstract An experiment was carried out to evaluate the requirement of methionine +cystine for growing pullets at starter phase (1 to 6 weeks old) and its effect on the laying phase. In the first experiment, 720 birds (50% Lohmann LSL and 50% Lohmann Brown) at one week of age were distributed on a completely randomized design, 5 x 2 factorial arrangement (levels of met + cys and strain), with four replications and 18 birds each. The levels of total methionine + cystine studied were 0.536; 0.616; 0.696; 0.776; and 0.856 %. At 22 weeks of age, 240 birds were used for the second experimental phase. The diets given to birds at this phase was the same for all the treatments. In the production phase, the residual effects of the experimental diets provided during the initial phase on the production parameters were evaluated. The level of methionine + cystine recommended for white-egg and brown-egg pullets in the period from 1 to 6 weeks of age are 0.778 % of total methionine + cystine (0.700% met + cis digestible) and 0.739% of total methionine + cystine (0.665% of digestible methionine + cystine), respectively.

title: Factors associated with efficiency in Primary Health Care, in brazilian municipalities

description: ABSTRACT This article aims to identify the factors that influence the efficiency in the application of resources destined to Primary Health Care in brazilian municipalities. To this end, the inflated beta regression model was used, since the dependent variable presents values in the interval (0,1]. According to the results, the Firjan Index of Municipal Development in health and basic sanitation services are factors that positively influence the average efficiency in the Primary Health Care of a municipality. On the other hand, the per capita expenditure of a municipality, in primary care, exerts a negative effect on the average efficiency.

title: FORAGE ACCUMULATION DURING THE STOCKING PERIOD ON PASTURES SUBJECTED TO INTERMITTENT STOCKING

description: Abstract The aim of this study was to evaluate the forage accumulation during the stocking period on Kikuyu grass pastures (Pennisetum clandestinum Hochst. Ex. Chiov) subjected to intermittent stocking. Treatments consisted of four defoliation levels (removal of 40, 50, 60, and 70% relative to the initial height) starting from the same pre-grazing height (20 cm). The following variables were evaluated: leaf and stem elongation rates (evaluated during four times across the period of occupation), leaf area index, and forage accumulation rates. Additionally, ten tillers/strip were evaluated for the same variables into exclusion cages. The linear, quadratic and cubic effects of severity of defoliation were evaluated by orthogonal polynomials contrasts with 5% of significance level. There was a linear and inverse relationship between the proportion of removed leaf area index with leaf elongation and herbage accumulation rate. The leaf elongation rate in individual tillers and the forage accumulation rates of tillers on excluded areas from grazing were greater than those under grazing. During the stocking period on pastures submitted to intermittent grazing, forage accumulation was observed and it was linear and negatively correlated with the proportion of leaf area removed.

title: EFFECT OF STRAINS AND SEXING ON PERFORMANCE AND CARCASS YIELD OF BROILERS

description: Abstract: We carried out this study to evaluate the productive performance and carcass yield of different strains and sexing of broilers. We evaluated 576 birds of Cobb, Ross, and Hubbard strains, arranged in male, female or mixed sexing, slaughtered at 45 days of age. We used a completely randomized design (CRD), in a 3 X 3 factorial (strain X sex), with four replicates per treatment. Body weight, weight gain, feed intake, and feed conversion showed significant differences in the course of the phases evaluated; however, they were similar at the end of the study period. Males showed superior results compared to females and mixed sexing. Carcass yield showed no significant differences among strains and sexing of birds; however, in some prime cuts, Cobb presented the best results.

title: PRODUCTIVE EFFICIENCY OF SHEEP WITH DIFFERENT CONFORMATION TRAITS UNDER GRAZING

description: Abstract: This study was carried out to evaluate the productive efficiency of Corriedale sheep of different conformation traits, reared on natural and/or cultivated winter pastures. At calving, the females were classified as medium (frame = 50 to 57.5 kg) and large (frame = 57.6 to 62 kg) regarding the size and as average (2 to 3 points) or high (3.5 to 4.5 points) regarding the body condition score. The experimental design was entirely randomized in a 2 x 2 factorial arrangement (two groups of body weights x two classes of body condition at calving). Sheep with medium body structure were lighter compared to large ones at calving (39.97 vs 48.16 kg, respectively) and at weaning (43.10 vs 50.22 kg, respectively). The production efficiency at calving and at weaning did not differ between medium (46.91 and 44.24 kg) and large sheep (47.83 and 45.69 kg), respectively. Sheep with average body condition at calving compared with sheep with high body condition showed no significant differences for productive efficiency at calving (46.89 vs. 47.82) and at weaning (44.10 vs. 45.83). The animal size and the body condition score at calving did not influence the production efficiency of sheep herds on grazing.

title: Addition of biostimulant to the industrial treatment of soybean seeds: physiological quality and yield after storage

description: Abstract: This study aimed to compare the results of germination, vigor, and yield of high- and low-vigor soybean seeds submitted to on-farm application of biostimulant with its application via industrial treatment 60 days before sowing. The experimental design was a factorial arrangement of 6 × 2 × 2 (technology × vigor level × strategy of biostimulant application) for the laboratory experiment and of 6 × 2 (technology × strategy of biostimulant application) for the field experiment. Germination, accelerated aging, emergence in sand, seedling dry biomass, and electrical conductivity were assessed in the laboratory, while stand, one thousand-grain weight, and yield were assessed in the field. Biostimulant application in soybean seeds not coated with pesticides did not affect the physiological quality regardless of the application moment (at the day of sowing or at 60 days before sowing). However, when applied in seeds coated with fungicides and insecticides, better results of germination, vigor, and yield were obtained with the on-farm use of biostimulant.

title: Analysis of Radar Cross Section Reduction of Fighter Aircraft by Means of Computer Simulation

description: ABSTRACT: This paper presents a preliminary study of the Radar Cross Section (RCS) reduction on the fighter aircraft. First, it was studied the RCS of the aircraft from computational simulations based on prior knowledge of vulnerable areas of this aircraft to radar threats. Subsequently, the possible applications of Radar Absorbing Materials (RAM) on the surface of the aircraft were evaluated, in order to reduce its RCS. The absorber material used in the simulations was denominated FC70, which has good attenuation in the range of 10 to 12 GHz. The study of this reduction was accomplished by applying RAM in four different scenarios at the frequency of 11.1 GHz, where the material is more sensitive. The RCS simulations of the fighter aircraft and its RCS reduction by RAM application were carried out with the support of the software "Computer Simulation Technology" (CST), version 2012. Such technology makes it possible to simulate the application with an absorber material layer on the surface of the aircraft. For the study of the RCS reduction on the fighter aircraft, it was first necessary to develop a detailed 3D model of the fighter aircraft, and it was developed with the software "Computer Aided Three-Dimensional Interactive Application" (CATIA). In conclusion, it is impossible to make much progress attempting to retrofit stealth onto a conventional aircraft because if the shape is wrong, no amount of absorbing material treatments will reduce the RCS.
