Productive performance of broiler chickens fed tomato waste
Lira, Rosa Cavalcante;Rabello, Carlos B?a-Viagem;Ludke, Maria do Carmo Mohaupt Marques;Ferreira, Paulo Vanderlei;Lana, Geraldo Roberto Quint?o;Lana, Sandra Roselí Valerio;

Abstract: aiming to evaluate the effect of tomato waste inclusion on productive performance and characteristics of carcass and main broiler chicken cuts, an experiment was carried out using 300 male cobb chicks, distributed in a complete randomized design, with five rations and five replicates. diets consisted of control ration based on corn and soybean meal and four rations with 5, 10, 15 and 20% of tomato waste. feed intake, weight gain and feed conversion and, at the end of experiment, slaughter weight, gutted carcass without feet and head, breast, drumstick, thigh, wing, back, edible guts and belly fat were evaluated every week, as well as it was the yield. tomato waste increased feed intake in the periods from 1 to 7, 8 to 14 and 29 to 36 days of age and worsened gain weight and feed conversion of broiler chickens up to 29 days of age. regarding carcass weight (g) and weight of the noble parts, breast, drumstick and thighs decreased linearly in function of the use of tomato waste in poultry on pre- initial and initial phase, that is, up to 28 days old, but yield (%) was not affected except for yield of heart and liver. use of tomato waste in ration of broiler chickens during the period from 1 to 28 days may decrease weight gain and worsen food conversion. tomato waste may be used as ration ingredient in ration of broiler chicken in the breeding period from 29 to 42 days of age up to the level of 20% without harming weight gain and feed conversion of poultry.
Inclusion of guava wastes in feed for broiler chickens
Lira, Rosa Cavalcante;Rabello, Carlos B?a-Viagem;Ferreira, Paulo Vanderlei;Lana, Geraldo Roberto Quint?o;Lüdke, Jorge Vitor;Dutra Junior, Wilson Moreira;
Revista Brasileira de Zootecnia , 2009, DOI: 10.1590/S1516-35982009001200016
Abstract: the objective of this study was to evaluate the effect of including guava wastes in the feed on the performance and carcass yield of broiler chickens. an experiment was carried out with 300 male cobb strain chicks, in a randomized complete design with five levels of waste and five replications. a reference diet based on corn and soybean meal and four feeds with 3, 6, 9 or 12% guava waste were evaluated. the feed intake, weight gain and feed conversion were assessed weekly; the weight at slaughter and the weight and yield of eviscerated carcass, carcass without feet and head, breast, drumstick, thigh, wing, back, edible viscera and abdominal fat were assessed. the inclusion of guava waste in the feed promotes performance and carcass yield similar to that obtained with the feed based on corn and soybean meal, therefore this agro-industrial by-product can be used at levels of up to 12% in feeds for broiler chickens.
O valor da biodiversidade e o impasse taxon mico: a diversidade marinha como estudo de caso
Paulo da Cunha Lana
Desenvolvimento e Meio Ambiente , 2003,
Abstract: Rather than an ecological concept, biological diversity is more and more evaluated as a real global resource, due to the advances of molecular biology and genetic engineering. However, not even taxonomical biodiversity is adequately known, as shown by the case of marine environments. About 200 000 species of marine plants and animais are currently known, but estimates ranging from 500 000 to 5 million species have been put forward. This paper critically assesses the concept of biodiversity, using marine diversity as a case study. Current needs of human and material resources to survey the variability of life in the oceans are appraised and discussed.

Novas formas de gest o dos manguezais brasileiros: a Baía de Paranaguá como estudo de caso
Paulo da Cunha Lana
Desenvolvimento e Meio Ambiente , 2004,
Abstract: This report assesses and presents alternatives to the current control and social appropriation model of Paranaguá Bay’s mangroves, including zoning suggestions and the eventual adoption of ownership management strategies. The basic suggestion is that the management of the regional mangroves should not be mistaken with strict conservation, as suggested by environmental legislation.
As marismas da Baía de Paranaguá: características gerais, modos de apropria o e implica es para a legisla o ambiental
Paulo da Cunha Lana
Desenvolvimento e Meio Ambiente , 2003,
Abstract: This review presents the current knowledge on salt marshes of Paranaguá Bay (Southem Brazil) and analyses their floristic, faunistic and physiographic differences in relation to local mangroves. Usage and traditional management of local salt marshes have received scant attention in the literature and their potential resources and ecological functions are heavily underestimated. A re-enactment of environmental law is suggested, on the basis of a comparative analysis between structural and functional attributes of local mangroves and salt marshes.
Epidemiologic Study of Ramularia areola under Different Soil Covers and Spacings, for Cotton Crops  [PDF]
Jaqueline Aguilla Pizzato, Dejania Vieira Araújo, Milson Evaldo Serafim, Kelly Lana Araújo, Rivanildo Dallacort, Thiago Alexandre Santana Gílio, Jair Romano Júnior, Vanderlei Antunes Maciel
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.411257

The objective of this work was to evaluate the progress of the areolate mildew of cotton under different soil cover and spacing conditions. The experiment was carried out using randomized blocks and a 2 × 3 factorial design, with two spacings (0.45 m and 0.90 m) and three soil covers (no cover, Pennisetum glaucum and Crotalaria spectabilis) with four replications. The plants were inoculated with R. areola, sixty DAS. A total of 14 evaluations of disease severity were performed. At the lower, middle and upper thirds of plants, a diagram scale with nine levels of severity was used and the resulting data were converted into the AUDPC. Gompertz, logistic, and monomolecular mathematical models were tested in the disease severity curves for each third. Agronomics characteristics were evaluated as well. Significant differences of AUDPC were found for the cotton plants thirds, and the middle third was the highest AUDPC. Significant difference for the lower and upper thirds, whose AUDPC were highest on 0.90 m spacing, was observed too. The disease progress curves of the thirds did not fit the tested models. Significant results to the both covers situations, where the treatments grown on crotalária cover and without cover had highest AUDPC, were evidenced. The treatments with C. spectabilis cover were taller than other treatments. Significant data were observed for the cover crops used and in the treatments grown at 0.90

Non-periodic bifurcation for surface diffeomorphisms
Vanderlei Horita,Nivaldo Muniz,Paulo Sabini
Mathematics , 2012,
Abstract: We prove that a "positive probability" subset of the boundary of the set of hyperbolic (Axiom A) surface diffeomorphisms with no cycles $\mathcal{H}$ is constituted by Kupka-Smale diffeomorphisms: all periodic points are hyperbolic and their invariant manifolds intersect transversally. Lack of hyperbolicity arises from the presence of a tangency between a stable manifold and an unstable manifold, one of which is not associated to a periodic point. All these diffeomorphisms that we construct lie on the boundary of the same connected component of $\mathcal{H}$.
