title: TROPICAL GRASS MANAGED UNDER INTERMITTENT LOTATION, SUBMITTED TO PHOSPHORUS SOURCES WITH DIFFERENT SOLUBILITIES, ASSOCIATED OR NOT TO NITROGEN FERTILIZER

description: Abstract The objective of this study was to evaluate the morphogenic and structural characteristics of piatã grass submitted to intermittent stocking and fertilized with phosphorus sources of different solubilities and nitrogen fertilization. The treatments were: control (without phosphate fertilizer application); slow solubility phosphorus source (FNR); fast solubility phosphorus source (FSS) and mixed solubility phosphorus source (FSM), whether or not associated with nitrogen fertilization. Measurements of pre-demarcated tillers were performed to evaluate the structural and morphogenic characteristics of the plants. Data were analyzed according to a randomized block design in a 4 x 2 factorial arrangement within each season. The minimum squared means of phosphate fertilizer treatments were compared with the control treatment by Dunnet test, and among themselves by the “t” test and the means of use or not of nitrogen fertilization were compared to each other by the “t” test at 5 % of significance. Sources containing readily available phosphorus, as in the FSS and FSM treatments, promoted greater leaf and stem elongation, as well as greater number and appearance of leaves, which highlights the importance of phosphorus and nitrogen availability in plant growth and development. confirmed by the increase in leaf elongation rate, leaf appearance and stem elongation. Thus, nitrogen and phosphate fertilizers are alternatives for the persistence and competitiveness of pasture livestock production. Regarding the source, the use of phosphorus sources with mixed solubility provides this nutrient in the short, medium and long term.

title: EFFECT OF ANTIOXIDANT SUPPLEMENTATION IN DIETS OF ROOSTERS DURING THE POST-PEAK PHASE ON REPRODUCTION AND PRODUCTION CHARACTERISTICS OF OFFSPRING

description: Abstract This study aimed to evaluate the effects of antioxidant supplementation in diets of breeding roosters during the post-peak phase on reproduction characteristics and muscle performance of offspring in two similar breeder houses from a local company. Treatments consisted of a control diet and a diet supplemented with antioxidants (8 ppm canthaxanthin + 40 ppm lycopene + 150 ppm vitamin C). During the 66th week of age, eggs were incubated, and offspring were housed. Dietary supplementation of the blend of antioxidant resulted in higher (p&lt;0.05) weights of testicles, crests, dewlaps, dewlap thickness, and number of perforations (53.35 x 25.30) in relation to non-supplemented roosters. There was no significant effect (p&gt;0.05) of supplementation of the antioxidant blend on weight gain and breast weight and count and diameter of muscle fibers of offspring at 7 days of age. Feed conversion and weight gain from 14 to 35 days were better (p&lt;0.05) in offspring from supplemented roosters. The supplementation of an antioxidant blend in roosters improved reproductive characteristics assessed and feed conversion and weight gain of offspring.

title: MORPHOGENIC AND STRUCTURAL CHARACTERISTICS OF SORGHUM FORAGE SUBMITTED TO THE CONTINUOUS LOTATION WITH SUPPLEMENTED BEEF STEERS

description: Abstract Morphogenesis is a valuable tool for the dynamics understanding of the pasture, however the morphogenetic studies related to sorghum culture are still scarce as well. The objective of the present study was to evaluate the effects of the different levels of supplementation on the morphogenetic characteristics of sorghum forage. The experiment was performed of UFSM from January to April 2013. The completely randomized experimental design was used, with measures repeated in time, with three treatments and two repetitions. The treatments consisted in S 0.8 = sorghum pasture + 0.8 % LW of supplementation, S 1.0 = sorghum pasture + 1.0 % LW of supplementation and S 1.2 = sorghum pasture + 1.2 % LW of supplementation. By increasing the supplementation level offered it was observed a lower value for the Number of Live Leafs (2.77, 3.34 and 3.55) and Leaf Elongation Rate (0.06, 0.09 and 0.08) characteristics. The variables Leaf Appearance Rate (0.0041, 0.0043 and 0.039), Leaf Senescence Rate (0.05, 0.06 and 0.11) and Phyllochron (283.96, 265.21 and 278.62) were not influenced (P˃0.05) by the different supplementation levels. There was a difference (P&lt;0.05) among the evaluation periods for Leaf Life Span (1081.1, 986.25 and 788.79) and Leaf Elongation Length (350.58, 312.83 and 326.36).

title: Social Innovation in Brazilian Social Entrepreneurships: A Proposed Scale for its Classification

description: Abstract Purpose: Social entrepreneurship and social innovation have attracted particular attention from policy makers, academics, and practitioners since the year 2000. As this area of knowledge is still incipient in the present literature, this study aims to develop and validate a scale to understand how social entrepreneurs identify social innovations generated by their entrepreneurships. Design/methodology/approach: In order to validate the scale, we applied it to 264 social enterprises in the 27 confederative units of Brazil. The statistical techniques used, besides the descriptive analysis of frequencies and central tendency and variability measures, were exploratory and confirmatory factor analysis. Findings: The results point to a validated scale consisting of 23 items that classify and identify social innovations of the product, organizational, and marketing types, and of incremental, disruptive, and institutional depths. Originality/value: The contribution to the understanding lies in the fact that the scale may stimulate social entrepreneurs or new entrants to better allocate their resources or their attention to certain types of social innovations in order to achieve better results for their entrepreneurships.

title: METABOLIZABLE ENERGY OF RICE BRAN, COTTONSEED MEAL AND WHEAT BRAN FOR SLOW-GROWING BROILERS AT TWO AGES

description: Abstract The aim of this study was to evaluate bromatological composition and metabolizable energy values of cottonseed meal, rice meal, and wheat bran when provided to slow growth rate broilers at different ages. Energy values of 15- to 25- and 35- to 45-day-old broilers were determined by the total feces collection method using two digestibility bioassays. The birds were distributed in a completely randomized experimental design to evaluate the age effect, with six replicates of 10 chickens each, for each ingredient. Values of apparent metabolizable energy adjusted by nitrogen balance (kcal/kg), for the first and second ages were: 1,255 and 1,564 for cottonseed meal, 3,124 and 3,301 for rice meal, and, 2,211 and 2,383 for wheat bran, respectively. The ingredients showed some variations regarding chemical composition and energy values, which were higher (P &lt; 0.05) in older broiler chickens.

title: Profile of high-risk pregnant women and co-management of the decision on the routh of birth delivery between doctor and pregnant woman

description: ABSTRACT Cross-sectional study carried out with survey data in four large Brazilian cities. This research analyzes data from Campinas (SP), aiming at characterizing the profile of high-risk pregnant women followed-up at specialized public outpatient clinics, as well as to verify and discuss aspects related to collaborative care in the decision on the route of birth delivery during the specialized prenatal care. The sample was calculated considering the prevalence of the high-risk pregnancy, morbidity profile and coverage of specialized services. Questionnaires were applied to 405 pregnant women of these services, and a descriptive analysis was performed based on the frequency distribution of the questions. The profile of pregnant women is mainly composed of young, black women, who have completed high school and without health insurance. There was a statistical association between variables: when women choose their own route of birth individually, the majority opts for normal birth; when only the doctor decides, the majority indicates cesarean section; and, when a joint decision is made the cesarean section prevails, but, in a lower percentage than when the doctor decides alone. It is necessary to discuss the power asymmetry between doctors and users in the care management as a fundamental component to qualify health work.

title: PERMANENCE OF WATER EFFECTIVENESS IN THE ROOT ZONE OF THE CAATINGA BIOME

description: ABSTRACT Soil is an important water compartment into a watershed scale, mainly due to its role in providing water to plants and to the influence of antecedent moisture on the runoff initiation. The aim of this research is to assess the permanence of water effectiveness in the soil under preserved-vegetation constraints in the Caatinga biome, in the semiarid northeastern Brazil. For this purpose, hourly soil moisture measurements were collected with TDR and analyzed between 2003 and 2010 for three soil-vegetation associations in the Aiuaba Experimental Basin. The results showed that in nine months per year soil moisture was below wilting point for two associations, whose soils are Chromic Luvisol and Haplic Lixisol (Abruptic). In the third association, where the shallow soil Lithic Leptosol prevails, water was found non-effective four months per year. A possible reason for the high water permanence in the shallowest soil is the percolation process, generating sub-surface flow, which barely occurs in the deeper soils. In situ observations indicates that the long period of soil moisture below the wilting point was not enough to avoid the blooming season of the Caatinga vegetation during the rainy periods. Indeed, after the beginning of each rainy season, there is a growth of dense green vegetation, regardless of the long period under water shortage.

title: Association of Respiratory Mechanics with Oxygenation and Duration of Mechanical Ventilation After Cardiac Surgery

description: Abstract Background: Mechanical ventilation (MV) and extracorporeal circulation (ECC) are associated with a decline in pulmonary mechanics that may affect gas exchange. Objective: To evaluate the impact of pulmonary mechanics on MV duration and gas exchange in the postoperative period of cardiac surgery. Methods: This was a cohort study in patients undergoing cardiac surgery. All patients underwent evaluation of pulmonary mechanics (static compliance and airway resistance) and arterial blood gas analysis upon admission to the intensive care unit (ICU) and were followed up until extubation and hospital discharge. Results: The study included 50 patients (46 women, 52%) with a mean age of 57.5 ± 13.5 years. The MV duration was 7.7 ± 3.0 hours, static compliance was 35.5 ± 9.1 cm H2O, resistance was 6.0 ± 2.3 cm H2O, mean length of ICU stay was 2.9 ± 1.1 days, and oxygenation index was 228.0 ± 33.4 mmHg. No significant correlation was found between MV duration and static compliance (p = 0.73), but a strong correlation was found between static compliance and gas exchange (r = 0.8 and p &lt; 0.001). Conclusion: Pulmonary mechanics have a strong correlation with gas exchange and a weak correlation with MV duration after cardiac surgery.

title: COTTON RESPONSE TO WATER DEFICITS AT DIFFERENT GROWTH STAGES

description: ABSTRACT Water deficit at certain cotton growth stages can cause severe damage to crop development, affecting physiological processes and reducing reproductive structures, with consequent yield losses. The objective of this study was to evaluate the response of cotton cultivars under water deficit applied at different stages of the crop cycle. We compared the number of bolls per meter, cotton yield, and water use efficiency for eight different cotton cultivars under a water deficit of 15 days. We selected the following growth stages: Emergence (EM), First Square (FS), First Flower (FL), Peak Bloom (PB), and First Open Boll (FOB). The control treatment was irrigated with 100% ETc. The experiment was conducted in Apodi, RN State of Brazil, semiarid region, using a sprinkler irrigation system. The number of bolls per meter, cotton yield, and water use efficiency were influenced by the interaction of cultivars x deficit periods. Lowest values were observed for water suppression in the FL and PB stages. When the water deficit was imposed in the initial stages of growth (EM to FS) or after the FOB stage, the cotton yield reduction was not significant. At the same stage and water deficit, the behavior of the different cultivars was similar. Producers are urged to take this information into account when developing irrigation schemes for cotton crops, thereby avoiding water deficits during the most critical periods of the crop cycle.

title: Elogio do anacronismo: para os andróginos de Ismael Nery

description: "Why praise anachronism when we are historians?" - asked Loraux. Anachronism was once a sin for historians, but has become a necessity. Approaching the issue from the perspective of some contemporary philosophers, such as Agamben, Rancière and Didi-Huberman, who rouse in our thought a new conception of time, this article argues that Ismael Nery (1900-1934), the "damned artist" of Brazilian Modernism, can be taken as an anachronistic artist. His art (painting, drawing and poetry) sets up temporal collages to express one of the principles of his philosophical system: the abstraction of time and space. The art of Nery presented itself as universal, mystical and spiritual, what placed him out of his time, or rather, out of the aesthetic representation that had been called upon to give visuality to the themes of the national.
