A cultura de índio, seu menino, vem de longe aqui : formação histórica e territorialização dos Tremembé/CE

This dissertation is based on the ethnography of a strategic selection of three Tremembé ethnic situations, which are situated in the backlands of Acaraú and Itarema, municipalities located in Ceará State (Northeast Brazil). My main aims are the following. Firstly, I reconstitute the historical and social formation of three localities, called Lagoa dos Negros, Telhas, and Queimadas, related to a particular origin myth which refers to Almofala, an extinct colonial Aldeamento in the seashore, where the Tremembé indians and other native populations were converted and gathered under missionary administration. According to the origin myth, these three localities were set up after a strong drought which happened in 1888 (the so called three eights) when a group of Tremembé families moved to the countryside and established close to the Lagoa dos Negros and, later on, they were segmented into smaller groups which started to live in other areas and places not far from the former location. Notably, I develop an anthropological approach to understand the historical formation of these three localities. Secondly, I analyze some processes of territorialization, which were emerged from the 1980s and had important consequences to these indigenous families throughout the next two decades. This historical dimension is re-appropriated and ressignified in ethnic terms. A third point of my work is the analysis of the construction of territorialities and also the cultural and symbolic dimensions which are formulated by the Tremembé Indians who live in these localities. Therefore, I investigate some cultural traditions and rituals, such as the Torém dance, but I also examine their multiple semantics, which constitute a transversal direction throughout the history understood by the Tremembé of the different social situations I researched. To sum up, there is a process of cultural actualization, which is still going on and presents itself through the ludic sphere as well as their political and religions dimensions, which are usually associated to the ritual presentation of the Torém

Avaliação das concentrações hepáticas e séricas de retinol em bovinos e do consumo habitual de fígado por gestantes

The vitamin A is essential to animals because of its participation in a great number of biological functions. The investigation of this vitamin s concentrations is important to serve as reference to normality parameters. This study had as aim to analyse the serics and hepatics concentrations of vitamin A in two groups of bovines and to compare the hepatics concentrations to the present requeriments of vitamin A for pregnant women. It was also appraised the consume habit of bovine liver by pregnant women through of the alimentary frequency quest. Two groups of bovine were studied and the first was formad by Nelore bovine breed and the second by bovine without defined breed (WDB). It was analysed 120 samples: 60 of liver and 60 of serum. The method used to dose retinol was High Performance Liquid Cromatography (HPLC). The average (+ sd) of retinol concentrations in Nelore breed bovine and WDB liver were 16947,8 + 6866,9 and 5213,1 + 2517,2 µg of retinol/100g and at serum 39,6 + 17,9 e 28,6 + 9,4 µg of retinol/dL, respectively. No statistically significant correlation was found between hepatic and the serum retinol. The bovines in this study had adequate vitamin A levels. Independently of animal breed, the daily ingestion of bovine liver is not advised for pregnant women who show adequate support of vitamin A. The consume of bovine liver by pregnant women consulted on school maternity hospital Januário Cicco, UFRN, Natal RN, was considered high

Avaliação de diferentes formas de preservação e desenvolvimento in situ de folículos ovarianos pré-antrais caprinos

This study evaluated the effect of indole-3-acetic acid (IAA) in the activation of goats preantral follicles (FOPA). Were used four pairs of ovaries of adult mixed breed goats. Each ovarian pair was divided into 23 fragments. One fragment was fixed for histology and other fragment was using to follicular isolation procedure. The remaining fragments were cultured in 1.0 ml of Minimum Essential Medium (MEM) or MEM supplemented with IAA at concentrations of 10, 40, 100, 500 or 1000 ng/mL. The in vitro culture was performed at 39°C in incubator with 5% CO2 for 1, 3 and 5 days. After in vitro culture was evaluated histological integrity and viability of FOPA. The addition of 100 ng/ml of IAA to MEM showed a significant increase in follicles transition in the third day of in vitro culture, characterizing follicular activation. Moreover, this concentration was obtained maintaining the histological integrity of PAF by the fifth day of in vitro culture. The viability test confirmed the results of histology. Thus, we conclude that IAA can promote the activation of goats FOPA

Aspectos ambientais e sociais envolvidos na transmissão da L. chagasi no município de Parnamirim/RN

Visceral leishmaniasis hás adapted in the past 20 years to periurban and urban areas, and in Natal, Rio Grande do Norte, it became endemic. Thid study aimed to evaluate the environmental and social aspectsof Leishmania chagasi infection and its epidemiologic transmission chain in an urban, periurban and rural area of Parnamirim-RN. A study with three sections was conducted: Section 1: Sectional study of the human and canine infection by L. chagasi and its environmental and social determinants. Section 2: Observational longitudinal cohort to evaluate the dynamics of the canine infection. Section 3: Longitudinal study to evaluate the behavior of Lu. Longipalpis vector and the seasonal factors related to its dynamics. To include in the study the hauses were randomly selected and georreferenciated. Montenegro skin test was done in the human population and blood samples were collected for anti-Leishmania antibody detection. The canine population was examinated for L. chagasi infection by RIFI, ELISA and ELISA for rK39. An entomologic surveillance was monthly done with CDC light trapsin 10 houses of each locality. Quantitative and qualitative analyses was done using STATISC 6.0. Probality and prediction maps were done using ArcGis 9.0 model. In the human population L. chagasi infection was associated with the area of the hause, age, sex, population densyti, vegetation, kind of the floor of thr hause, water and resides destiny. In the canine population L. chagasi infection was associated with the breed, size, time of living in the hause, presence of dogs in the neighborhood, presence of horses and donkeys in the neighborhood, vegetation, kind of the floor and walls of the hause. The human infection was associated with canine infction only when analyzed taking into account the locality. In the prospective study, serum conversion and antibody lost observed in 30,8% and 22% of the animals examined, respectively. The human infection rate by L. chagasi was 24,6%, by the presence of anti-Leishmania antibody and 38,6% by the Montenegro skin test. The canine infection rate 32,5% by the presence of anti-Leishmania antibody. The vector Lu longipalpis showed an atypical behavior. These results indicate that environmental and social factors are important variables associated with L. chagasi infection in humans and canines, with punctual association of thr last two. Control measures of the infection on the studied points are necessary, in the aim to reduce the endemic focus of the disease in the study area. This research was carried out in a multidisciplinary involving the categories of: doctor, biologist, veterinarian, statistical, pharmaceutical and biochemical

Parâmetros parasitológicos e desempenho produtivo de ovinos naturalmente infectados com nematoides gastrintestinais mantidos em diferentes pastagens tropicais

The control of gastrointestinal nematodes of small ruminants is usually done with anthelmintics. However, due to the emergence of ever-increasing parasite resistance to these drugs, looking up an alternative control parasites. One of this is sought in pasture management, as these are the sources of animals` infection by L3 infective larvae of helminths. The aim of this study was to evaluate the performance of sheep to natural infections by gastrointestinal nematodes grazing Panicum maximum cv. Massai and cv. Aruana, and Brachiaria brizantha cv. Piatã and cv. Marandu. The work was conducted from May to August-2011 with 48 male sheeps SRD versus Santa Inês breed. The animals were naturally infected with gastrointestinal nematodes, and maintained in four different cultivars of tropical forage grasses, naturally contaminated with eggs and larvae of gastrointestinal nematodes. Each week the animals were phenotypically characterized by parasitological examinations (eggs per gram of feces - EPG, and feces culture), hematological (packed cell volume PCV, and blood eosinophil count) method to evaluate the Famacha© colorof ocular mucosa, and the measures of body condition score and weight. In pastures was made the recovery of infective larvae in order to determine the quantity of L3 present in the pasture. The experimental design was a randomized completed block with two replications and before the entry of animals in the paddocks, they have been wormed. The experiment was ended when the animals reached 32.0 kg liveweight, and then were slaughtered and autopsies performed for the recovery and identify parasites of the abomasum, small intestine and large intestine. Results were subjected to analysis of variance, t test and Tukey`s test. The animals kept on pastures of Marandu grass had lower EPG counts, higher percentage of packed cell volume and higher average weight; those who remained in the Piatã pasture had lower eosinophil counts per microliter of blood. About the Famacha©, the highest prevalence was Famacha 2, and the body condition score ranged between 2 and 3. The results of feces cultures and recovery of larvae on pastures showed the presence of larvae of Trichostrongylus sp., and at the necropsy too. This way, it was concluded that the grass cultivars influences the sheep parasite load; the Famacha, together with EPG and packed cell volume are important indicators for use in controlling gastrointestinal nematode infections. The Trichostrongylus sp. was the most prevalent parasite in sheep during the rainy season

Valor nutritivo de fenos de moringa (moringa oleifera lam) com diferentes idades de corte

This study was conducted to evaluate the consumption and digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), total carbohydrates (TC), non-fiber carbohydrates (NFC) and neutral detergent fiber (NDF) in sheep fed hay moringa (Moringa oleifera Lam) obtained with four cutting ages (28, 35, 42 and 49 days). We used 20 females Morada Nova breed, with 20kg of live weight, distributed in a completely randomized design and maintained in metabolism cages. There was a negative linear effect of age of cutting on DM intake, with an estimated maximum consumption of 0.67 kg / day for the hay produced at 28 days of cutting. It was also observed linear behavior, with an estimated maximum consumption 172g/dia, 0.36 kg / day; 18g/dia, at 35, 42 and 49 days old, for CP, OM and EE, respectively. For NDF, quadratic effect was found with advancing maturity of the plant. The apparent digestibility of DM, CP, OM and TC linearly decreased with advancing age of cutting hay Moringa oleifera. It was concluded that the hay Moringa oleifera showed better nutritional value after 28 days of cutting

Avaliação genética da eficiência reprodutiva em vacas pardo-suíças por meio da análise de sobrevivência

Among the traits of economic importance to dairy cattle livestock those related to sexual precocity and longevity of the herd are essential to the success of the activity, because the stayability time of a cow in a herd is determined by their productive and reproductive lives. In Brazil, there are few studies about the reproductive efficiency of Swiss-Brown cows and no study was found using the methodology of survival analysis applied to this breed. Thus, in the first chapter of this study, the age at first calving from Swiss-Brown heifers was analyzed as the time until the event by the nonparametric method of Kaplan-Meier and the gamma shared frailty model, under the survival analysis methodology. Survival and hazard rate curves associated with this event were estimated and identified the influence of covariates on such time. The mean and median times at the first calving were 987.77 and 1,003 days, respectively, and significant covariates by the Log-Rank test, through Kaplan-Meier analysis, were birth season, calving year, sire (cow s father) and calving season. In the analysis by frailty model, the breeding values and the frailties of the sires (fathers) for the calving were predicted modeling the risk function of each cow as a function of the birth season as fixed covariate and sire as random covariate. The frailty followed the gamma distribution. Sires with high and positive breeding values possess high frailties, what means shorter survival time of their daughters to the event, i.e., reduction in the age at first calving of them. The second chapter aimed to evaluate the longevity of dairy cows using the nonparametric Kaplan-Meier and the Cox and Weibull proportional hazards models. It were simulated 10,000 records of the longevity trait from Brown-Swiss cows involving their respective times until the occurrence of five consecutive calvings (event), considered here as typical of a long-lived cow. The covariates considered in the database were age at first calving, herd and sire (cow s father). All covariates had influence on the longevity of cows by Log-Rank and Wilcoxon tests. The mean and median times to the occurrence of the event were 2,436.285 and 2,437 days, respectively. Sires that have higher breeding values also have a greater risk of that their daughters reach the five consecutive calvings until 84 months

Produção de ovinos em pastagem de capim-massai suplementados na estação seca

The low quality of tropical pastures in the dry season justifies the use of dietary supplements to meet the nutritional needs of sheep to meat production. Therefore, the objective of this experiment was to evaluate the agronomic characteristics of massaigrass in the dry season and the effect of protein supplements in the performance and productivity of sheep to meat production grazing. The protein supplements evaluated were: soybean meal, Leucena hay, Gliricidia hay and multiple mixture. The animals were managed in massaigrass pastures under rotational stocking and supplemented daily. Were used 24 sheep ½ Santa Inês x ½ SPRD (without defined breed), males uncastrated, mean age 90 days in a completely randomized design. Performance of sheep was evaluated for average daily gain of live weight gain per area and stocking rate (animals of 25 kg/ha). The pasture was evaluated for forage mass of pre and post-grazing, the percentages of participation of morphological constituents and their nutritional values and rates of herbage accumulation. The total herbage mass decreased throughout the dry season. Crude protein and in vitro digestibility of organic matter of the leaf were higher in the upper 15 cm of the canopy stratum. The average daily weight gain of the animals supplemented with legume hay was similar to that gained by animals supplemented with soybean meal in the four grazing cycles. The total live weight gain of animals supplemented with legume hay was higher than the animals supplemented only with multiple mixing the first two grazing cycles. Hays of Leucena and Gliricidia can be given for supplementation of sheep maintained on pasture

Moradores crônicos de hospital psiquiátrico: um desafio à desinstitucionalização

The existence of chronic inhabitants in the psychiatric hospitals imposes a challenge to the Psychiatric Reform, that proposes things such as the gradual and progressive way to extinct mental institutions, once the permanence of the hospital in the system is only necessary because there is not a net of well structured substitute services capable of receiving that demand. This work considered relevant to deepen the knowledge about those people who passes their lives jailed by the walls of psychiatric hospitals and compose significant part of the world population. It also aimed to investigate the problem relative to the condition of being an inhabitant of a psychiatric hospital the Dr. João Machado Hospital (HJM), in the city of Natal/RN. The paper used different points of view (patients , families and professionals ) to define the profile of the inhabitants, to identify the possibility of insertion in substituting social equipment, to know the expectations of the inhabitants and their relatives regarding to the exit of the life shelter, to investigate the demands related to the net of cares social support for making feasible the discharge and to identify the difficulties that are involved in the exit of the chronic inhabitant of the hospital. There were defined three methodological phases: delineation of the identification, socio-economic and clinical profile of the inhabitants of the HJM; semi-structured interviews with professionals; and open interviews with inhabitants and family. It concluded that the psychiatric institutionalization contributes to the generation of chronic inhabitants in the psychiatric hospitals. Among the professionals, it was detached the defense of desospitalization, but an existence of devices of the asylum model. The relatives showed a resistance to participate in the care and the inhabitants exposed their desire to leave the hospital, as well like the wish of permanence. It was considered important: the construction of an extra-hospital net that enables to desinstitutionalization; the qualification of the technical; orientation to the family, stimulating its participation in the process of caring; give freedom to the individuals in mental suffering, enabling them to be ahead of their lives and express their desires and opinions; the implementation of an extended clinic that is capable of building new possibilities; and a subjectivity guided by the social enclosure

Famílias privadas de liberdade: a saga da violência vivenciada por adolescentes que trilham os áridos caminhos da criminalidade

This paper has as its main focus the relation between the infringement act and the adolescents families social economical problematic, who obey the social educational deprivation of freedom at CEDUC in the district of Pitimbu RN, establishing in the theme Children and Adolescents, with the objective of showing how these families breed in the social economical and cultural political aspect. It also seizes who those adolescents are and their family members in their social aspect and as those families face their daily activities. The focus on the social matter, family, adolescent, infringement act, exclusion, inclusion formed the analysis categories which made myths and reality possible, taking into consideration the infringement act in our society. The data collection showed that those families conditions of life are of poverty. Families originated from low social classes, 62.5 % coming from the countryside and living with a daily income ranging from R$ 0,31 to R$ 8,31. Their level of education is low; there is lack of human and citizenship rights and no professional qualification whatsoever. It questions the degrading social exclusion suffered by millions of Brazilian people due to social, political and infringement economical problems. Has this favored the infringement practice? How to confirm the families lack of competence having the social vulnerability? Are the Public Political Institutions really performing the way they should? Are they really carrying out their role as they should? We have noticed that from then on, the necessity of understanding the exclusion/inclusion suffered not only in an imprecise and empty way, but understood as processes of integrative exclusion or ways of delinquency, where the excluding is not only the only one who has lack of material care but the one who is seen or recognized as a person, is not being treated as one. The effort of this paper provided an approach to our object, and the seizing of a close relation between the infringement act and the exclusion process or inclusion suffered, which are submitted to families of those adolescents who deprive of freedom
