Níveis nutricionais de cálcio para aves de corte ISA Label criadas sob semiconfinamento

Determinaram-se os níveis nutricionais de cálcio (Ca) para aves, machos e fêmeas, da linhagem ISA Label, nas fases inicial (um a 28 dias), crescimento (28 a 56 dias) e final (56 a 84 dias). Foram realizados três ensaios, um para cada fase, e, em cada ensaio, 480 aves com idade correspondente à fase de criação foram alojadas em 24 unidades experimentais com áreas de abrigo e de pastejo. Foi utilizado delineamento inteiramente ao acaso, em esquema fatorial 4x2 (Ca e sexo), totalizando oito tratamentos com três repetiç ões de 20 aves. Avaliaram-se: ganho de peso (GP); consumo de dieta (CD); conversão alimentar (CA); teores de fósforo (PT), de cálcio (CaT) e de cinzas na tíbia (CT) e resistência à quebra óssea (RQO). Na fase inicial, recomenda-se 1,16% de Ca na dieta, para aves de ambos os sexos, na fase de crescimento, 0,78 e 0,88% de Ca para machos e fêmeas, respectivamente, e, na fase final, 0,69% de Ca na dieta para ambos os sexos.

Efeitos das variáveis ambientais locais sobre a abundância, a riqueza e a biomassa da macrofauna de solo em um ecossistema semiárido no estado do rio grande do norte, nordeste do brasil

The soil macrofauna is influenced to several biotic and abiotic environmental factors, from changes in the physical environment to a variety of interactions among the species involved, affecting the patterns of biodiversity of soil fauna. The power and specificity of the mechanisms that act on soil organisms vary greatly depending on environmental conditions at different scales of space and time. The Caatinga has great spatial heterogeneity of vegetation, climate and soil, so the soil macrofauna would follow this local spatial variation in the environment? This study aimed to investigate the effects of local environmental variables on biological parameters (taxa richness, total abundance and biomass) of soil macrofauna in a fragment of caatinga in João Câmara, Rio Grande Norte, Northeast Brazil. The study was conducted in the Cauaçu farm, where a grid of 2000m x 500m was drawn, and later, 30 sampling points were randomly selected. The methodology used to collect the macrofauna was the TSBF method. We tested the effects of 10 environmental variables on macrofauna across the plots and across the layers of soil. The hypothesis that macrofauna soil responds to changes in the environment was not supported throughout the plots, but was confirmed to soil layers. The soil macrofauna shows a pattern of concentration in the surface layer and decreases considerably in the deeper layers. This pattern had significant and positive relationship with the aerial plant biomass and fine root stock. The aerial plant biomass releases plant necromass that accumulates in the surface layer, providing an important source of resource and shelter for soil macrofauna, explaining their greater abundance in this layer. The roots are used as a means for the arrival of nutrients to the soil from the primary production, thus a greater amount of root conditions higher food intake for macrofauna, especially the herbivores

Aspectos biológicos de Harmonia axyridis alimentada com duas espécies de presas e predação intraguilda com Eriopis connexa

O objetivo deste trabalho foi determinar os aspectos biológicos de Harmonia axyridis, alimentada com duas espécies de presas, e a ocorrência de predação intraguilda com Eriopis connexa. Larvas de H. axyridis foram alimentadas diariamente com ovos de Anagasta kuehniella ou com o pulgão Schizaphis graminum. Adultos da joaninha foram separados em dez casais que receberam o mesmo tipo de alimento da fase larval. Na avaliação da predação, uma larva de quarto instar de cada espécie foi mantida na presença ou ausência de abrigo e de ovos de A. kuehniella. A fase larval de H. axyridis durou 10,2 e 8,9 dias, quando alimentada com A. kuehniella e S. graminum, respectivamente. A sobrevivência do predador, em fase imatura, variou de 70 a 100%. A joaninha apresentou período de oviposição de 47,3 e 51,7 dias, com 887,6 e 822,5 ovos, ao se alimentar de A. kuehniella e S. graminum, respectivamente. A longevidade das fêmeas foi de 74,1 e 76,2 dias e a dos machos de 67,3 e 70,3 dias, em A. kuehniella e S. graminum, respectivamente. H. axyridis atuou como predador intraguilda e foi a espécie dominante na competição com E. connexa.

A videobiografia como dispositivo de pesquisa-ação-formação: uma prática educativa com adolescentes abrigados

The focus of this thesis is a production of video biographies with/by sheltered teenagers. The general objective is discuss the potential production of video biographies while a device of research-action-formation. From de point of view of research, the study interrogates cultural practices that demarcates the passage of teenagers in shelter institutional; From the point of view of action, seeks to identify the modes of appropriation of space for audiovisual creation by teenagers; and, from the point of view of formation, asks the potentiality of audiovisual language while the way from which teenagers can auto-configure themselves responsibly, in the reinvention of places and others worlds for them. The research falls in the intersection of qualitative approach of ethnographic and of research-action-formation. Is anchored theoretically in autobiographical approaches - Pineau (2005); Passeggi (2008); Delory-Momberger (2008); Josso (2010) e Bertaux (2010) - and in the filmic method - Ramos (2003); Wohlgemuth (2005) and Comoli (2009). Participated in the research eleven teenagers members of the production cycle of biographical traces, among these, the three teenagers who advanced to cycles of audiovisual recording life narratives and reflective exercises around produced reports, procedures of which we extract the set of empirical material analyzed The analysis revealed that teens use in under three types of practices: the practices of mess , as way of expression; the practices of evasion , as resistance to restraint the right to come and go, and the practices of claim a regime of "truth" to the institutional environment, which emerge as a survival tactic in the face of paths desvínculos, family abandonment and neglect. The study also showed the appropriation of spaces of audio-visual creation meaningful expression through music by teenagers and encourage dialogue between and with the teenagers and the achievement of reflective exercises focused for awareness of their stories in becoming. These findings show a broader sense the thesis that visual language is a potent mobilizer artifact reflections and empowerment of individuals in situations of social exclusion

Sair curado para a vida e para o bem: diagramas, linhas e dispersão de forças no complexus nosoespacial do Hospital de Caridade Juvino Barreto (1909-1927)

This work has as object of study the Hospital de Caridade Juvino Barreto, nosocomial institution located in the city of Natal (RN), between the Praia de Areia Preta and the Monte Petrópolis, focusing on the period from 1909, the year in which the new hospital building was constructed and opened, and 1927, the date of the transfer of administration of the public domain to the newly created Sociedade de Assistência Hospitalar (SAH). We study the conditions of possibility of the emergence of this hospital space in the urban environment of the capital of Rio Grande do Norte, seeking to understand the different tactics and strategies implemented by the historical subjects involved in the formation of this institution nosocomial. Starting from a corpus of documents consisting of medical memories (with Dr. Januário Cicco as privileged observer), information present in newspapers (the Republic and the Christmas Journa l), photo collection and extensive administrative and legal material (Speeches, Exhibitions, Reports, Laws and Resolutions), we analyzed in detail the medical geography of HCJB, relating the discourses of medicine and geography in choosing the spatial location of the hospital as we examine the architecture of the hospital, its inner spat iality, divisions, forms of space control, and, finally, we discuss the medical practices that took place within it, leading us in this regard, from the experiences of clinical hospital chief, Dr. Januário Cicco, especially the discussion on "ethics" in hospital work. The perception of HCJB as medical nosoespaciality always on the move, incorporated under taxonomic principles based on difference and dispersion forces, led us to articulate it theoretically from the conceptual-methodological arsenal of philosopher Michel Foucault, particularly his reflections of genealogical phase, focusing on the phenomenon of power, a position that allows us to enhance our space-hospital construction, invention, product of power relations, which give the unfinished aspect nosocômio, apparent, always at stake, perpetual non-modeling possibility has previously defined array, establishing it at the field of possible, of virtuality, of power: hospital that could have been and that it was not. Indeed, the investigation of various aspects/elements of hospital space Juvino Barreto revealed us new dimensions of hospital space, far more complex than the simple and the current idea of a place to shelter patients: plasticity and fluidity of space, which is not made to circumscribe the limits of empeiria, engraving up to strength relations fought between different subject; its Constitution as a transitional space, Heterotopic, doing live inside modern elements with premoderns (professional doctors working with religious thought, skeptical of positivist medicine living with the religious faith of the nuns of Santana); the impossibility of thinking hospital space of HCJB while homogeneous unit, static, transistoric, making the spatiality, without considering the profound differences, fractures and dislocations that animated his own existence, multiplying their expressions of identity

Comportamento do camarão de água doce macrobrachium rosenbergii (De Man, 1879) em cultivos misto e monossexo

Understanding the behavioral activities of freshwater shrimp in captivity is of paramount importance for the appropriate management of the species. In Brazil, the shrimp Macrobrachium rosenbergii is currently the most widely used species in the freshwater shrimp culture due to its high potential for cultivation and good market acceptance. Thus, the present study aimed to describe and characterize the behavioral activities of M. rosenbergii in monosex and in mixed (male and female) (manuscript 1, 2 and 3) populations and the growth performance of this species in restrictive feeding conditions and in different feeding management (manuscript 4 and 5, respectively) . Juvenile and adult shrimps were collected from ponds of the Aquaculture Station - Unidade Especializada em Ciências Agrárias - Universidade Federal do Rio Grande do Norte (UFRN), Macaíba/RN and then transferred to the Laboratório de Estudos do Comportamento do Camarão LECC (Laboratory for Shrimp Behavioral Studies) of the Universidade Federal do Rio Grande do Norte (UFRN). For each treatment , eight aquaria of 250 L (50 cm x 50 cm x 100 cm) were used in a closed recirculating water system with artificial lighting, constant aeration , continuous filtration through a biochemical and biological filter (canister filter), and fine sand as substrate . The water quality was monitored daily. The lab consisted of two rooms with artificial lighting system , controlled by a timer with dark / light cycle of 12:12 h . In manuscript 1, the behavioral categories of the species were presented through an ethogram, which described 31 behaviors, subdivided into general and agonistic behaviors. Manuscript 2 compared the behavioral profile of shrimps in male and in female monosex and mixed populations over 24 hours in laboratory. In three types (mixed, male monosex and female monosex) of populations during the light and dark phases of the 24 hour cycle, the shrimps showed higher occurrence of cleaning behavior. Manuscript 3 examined the influence of the color of the shelter on the frequency of its use and behavioral activities of shrimp in mixed, in male monosex and in female monosex populations over 24 hours. We observed that the shrimp M. rosenbergii burrow more frequently during the light phase in male monosex and mixed populations; they also tend to choose the black shelters. Female monosex populations tend to use red and orange shelters. In manuscript 4, we evaluated in laboratory the behavioral activities and growth performance of juvenile shrimps under food restriction. We observed that a mild food restriction may be used since there is no loss concerning the growth of the animals; feeding management on alternate days , compared to daily management can be financially productive both reducing labor costs and reducing the amount of feed used . Manuscript 5 evaluated the behavior of shrimps in monosex and in mixed populations, as well as the latency of reach the food according to feed offer (tray or food dispersal) . Our results indicate that animals adjust to both types of feed offer food dispersal as much as tray, but they spend more time to reach the feed when it is offered in trays (feeders). Comparing culture types (mixed, male monosex and female monosex), the latency to reach the food was lower for female monosex population. The data obtained in this study demonstrate the importance of identifying different pressures and environmental stimuli on the behavioral responses of this species. This knowledge would support management improvement to optimize the levels of animals‟ welfare, resulting in a better zootecnical performance

Sentidos e perspectivas atribuídos por crianças à sua condição de estar para adoção

Considering the Brazilian current context, where many children are in institutional shelter waiting for adoption, the aim of this study was to know the meaning that sheltered children (whose families had already lost their custody or were in the process of losing it, at the moment of the field work) gave to their adoption condition. The research was carried out with three children in the shelter where they lived, in Natal, Rio Grande do Norte, Brazil. The field work took six months approximately. In order to meet the objective of this research, individual procedures were structuralized using figures and drawing material. With these procedures the children could speak directly or indirectly about the application of the legal measure of institutional shelter, about their lives before the application of this legal measure and what happened since then, and their original families and future perspectives. The content of the procedures was tape recorded and registered in the field work diary. The analysis of the corpus occurred with the Thematic Content Analysis, considering the theoretical methodological perspective of the Net of Meanings approach. The analysis of the corpus showed the ambiguity of the children, who consider good to live in the institution where they are, recognizing the responsibility of the original caregivers for their sheltered condition and, at the same time, they miss their relatives and wish to be with them. The subjects recognize the perspective of adoption and imagine it in a positive way. However, when the children were questioned about what could happen to them in the future, they said that they did not know, expressing uncertainty concerning their destinations

Mulheres em situação de violência e atenção em saúde mental: um estudo no município de Natal (RN)

The present study aims to meet the attention given to women with mental health needs in specialized services for the fight against violence against women, as well as psychosocial care network in the municipality of NatalRN. It is a qualitative research characterized as research-intervention that took place in the year 2011. The study started in the Centre of Reference in which individual semi-structured interviews were carried out directed to the coaching staff and manager, in order to know the care offered in relation to the aforementioned clientele. From the Reference Centre were identified through analysis of registration records, the routes traversed by users through the network of psychosocial care and hospital network. After the identification of the same were visited two day-care Centers, two psychiatric hospitals, a basic health Unit and the local shelter. In these organizations was investigated the reception and procedures offered to users in situations of violence, the knowledge of policies for women and the coordination with the attention to women, through interviews with semi-structured individual scripts directed to professionals. The interviews were analyzed taking as starting point the theoretical framework of French Institutional Analysis, which includes the assumption of events analysers for the critical reading of dimensions introduced in the practices of care of the teams that took part in the study. The survey results revealed difficulties on the part of the same host of users with this profile, both in the face of violence as services in mental health services. This fact led to the lack of support under the guarantee of their rights, ceasing the possibilities of confronting the situations of violence, as well as in the context of mental health care
