25. Eclectic feeding behavior of Lutzomyia (Nyssomyia) intermedia (Diptera, Psychodidae, Phlebotominae) in the transmission area of American cutaneous leishmaniasis, state of Paraná, Brazil
Introduction The blood meal source of sandflies provides valuable information about the vector/host interaction and allows for an understanding of American cutaneous leishmaniasis (ACL) transmission mechanisms. The aim of this study was to identify the blood meal sources of Lutzomyia (Nyssomyia) intermedia in an endemic area of leishmaniasis in Brazil's St

26. Vultures and others scavenger vertebrates associated with man-sized pig carcasses: a perspective in Forensic Taphonomy
The activity of vertebrates that feed on corpses can modify the chronology of the decomposition process and interfere with postmortem interval estimates. Further, by destroying the soft parts of the cadaver, scattering, burying or causing the disappearance of bones, it can entirely change the crime scene. In this study, we simulated a clandestine cemetery in

27. Effect of pectin extracted from citrus pulp on digesta characteristics and nutrient digestibility in broilers chickens
The experiment was carried out to evaluate the effects of continuous ingestion of pectin on intestinal viscosity, intestinal transit time, excreta moisture content, nutrient digestibility and energy metabolism of broilers at starter and growth phases. We used 240 one-day-old Cobb male broiler chicks, distributed in a completely randomized experimental design

28. Effects of pre-slaughter fasting on broiler welfare, meat quality, and intestinal integrity
The Brazilian Ministry of Agriculture (MAPA) regulations establish 12 hours as the maximum pre-slaughter fasting period for broilers; however, many processing plants have considered this time is not sufficient, and consequently return the birds to the farms, with consequent economic losses and welfare problems. Therefore, it is necessary to investigate the p

29. Transgredir, jamais! Interação e cortesia linguísticas nos manuais de etiqueta / Transgress, never! Linguistic interaction and politeness inside etiquette manuals
This thesis discusses communication as an interaction-dependent factor and linguis-tic politeness inserted in etiquette manuals, in order to explicit and implicitly identify the interactional strategies presented by three authors chosen as corpus, which is comprised of some parts chosen from three manuals of behavior: 1) Marcelino by Claudia: the guide to go

30. Relação entre distribuição espacial e sensibilidade à fragmentação florestal : um estudo de caso em aves suboscines do norte do Estado do Paraná
História evolutiva e especificidades ecológicas das espécies determinam seus níveis de sensibilidade à fragmentação florestal. A especialização à microhábitats, ou seja, a exploração de recursos específicos do ambiente florestal, é descrita como uma das características determinantes de sensibilidade e é diretamente influenciada pela heteroge

31. Chlorine requirement for Japanese laying quails
The objective of this study was to determine the chlorine nutritional requirement of Japanese Quails during the laying phase, based on performance and egg quality parameters. A total of 240 Japanese quails were distributed according to a randomized block design, with five treatments and six replicates, with 8 birds each. The experiment lasted 84 days, divide

32. PARÂMETROS IMUNOLÓGICOS FRENTE À CONTAMINAÇÃO POR SALMONELLA ENTERITIDIS EM AVES TRATADAS E NÃO TRATADAS COM ÁCIDOS ORGÂNICOS E SUA DETECÇÃO POR MÉTODOS FENOTÍPICOS E GENOTÍPICOS / IMMUNOLOGICAL PARAMETERS IN THE CONTAMINATION BY SALMONELLA ENTERITIDIS IN POULTRY TREATED AND NOT TREATED WITH ORGANIC ACIDS AND THEIR DETECTION BY PHENOTYPIC AND GENOTYPIC METHODS
Salmonellosis is a public health problem that involves issues in animal health and food handling practices that require combined actions to minimize its effects. This disease is a zoonosis with the greatest impact on public health throughout the world due to: high endemicity, high mortality and especially by its difficult to control and the development of an

33. Genetic Algorithm for the solution of majority problem / Algoritmo genÃtico para a soluÃÃo do problema da maioria.
Many natural and social systems exhibit globally organized behavior without the aid of a centralized control. Examples of such decentralized systems include conventions and norms, social learning in animals and humans, as well as fads, rumors and revolts. Examples are also abundant in biology: the evasive behavior of animals in large groups, such as fish and

34. Variabilidade do ambiente térmico em galpão para frangos de corte e sua influência nas respostas fisiológicas e comportamento das aves / Variability of thermal environment in barn for broilers and its influence on physiological responses and behavior or birds
The experiment was conducted in a barn with 21,000 Cobb male broilers, in order to characterize the variability of the thermal environment in a broiler barn and verify if the physiological responses and behavior are influenced by it. The treatments consisted of five 25 m-long sections (S1, S2, S3, S4 and S5) along the hall, set in ascending order from the ai

O experimento foi conduzido em galpão comercial com 21.000 frangos de corte, machos, da linhagem Cobb, com o objetivo de caracterizar a variabilidade do ambiente térmico de um galpão de frangos e verificar se as respostas fisiológicas e o comportamento das aves são influenciados pelo mesmo. Os tratamentos consistiram de cinco seções (S1, S2, S3, S4 e

36. Water intake behavior of broiler chickens exposed to heat stress and drinking from bell or and nipple drinkers
The aspects involved in broiler water intake are not well known, despite the importance of water in animal nutrition and physiology. Water intake behavior should be taken into account when deciding on different types of drinkers. Bell and nipple drinkers are the most commonly used in commercial broiler production. Broilers were housed in cages equipped with
