Crônicas Da Morte Revivida Na Luta: Uma Etnografia Da Romaria Dos Mártires Da Caminhada Em Ribeirão Cascalheira (mt), Brasil
The purpose of this article is to discuss some aspects that compose a ritual sacralization of popular leaders, killed in areas of intense land conflicts in Brazil, and their transformation into martyrs of the land. The Martyrs of the Walk Pilgrimage which provides the basis for this analytical incursion took place between 16 and 17 July 2011, in Ribeirão Cascalheira (Mato Grosso). The agency of these martyrs seems to be based on individual skills, recognized and legitimized within the group itself, both because of their trajectories of struggle and resistance and their training by religious and Catholic missionaries linked to the Liberation Theology. In this direction, if while living their work with peasants and indigenous groups was intense, when they are dead their presence is often triggered and ritualized. This enterprise suggests that the dead man’s active memory, linked to the active memory of the struggle, enables the active presence of the dead in the struggle. © CRIA.20233936
Performance And Economic Analysis Of Finished Lambs In Feedlot
This study aimed to evaluate animal performance and economic performance of feedlot crossbred lambs (Santa Inês+ - Suffolk) fed different diets based on hay from Cynodon dactylon genotypes, through the use of financial measures considering only the period of feedlot, without relating it to the complete management cycle. A total of 30 intact crossbred Suffolk lambs, identified with earrings, with an average age of 90 days and an average body weight of 21.5 kg were used in this study. Diets were formulated using as treatments a standard concentrate and hay of the Cynodon dactylon genotypes Jiggs, Vaquero, Tifton 68, Coast-Cross, Tifton 85 and Russell in a 60:40 forage-to-concentrate ratio. The treatments were distributed in a randomized complete block design with five replicates. There were significant differences between diets in terms of total expenditure on food, and the highest values were obtained for the Jiggs genotype (BRL 48.96/animal). The animals fed diets based on Tifton 68 hay had a higher rate of return (2.16%) and profitability (34.63%) compared to the other diets. The use of diets based on Tifton 68 hay for feedlot lambs in the finishing phase brings higher economic returns compared to the remaining diets.37129330
Assessment Of Visual Health Campaign Activities At Schools - Teachers' Perception
Purpose: 1) To assess the opinion of teachers involved in visual screening of school-age children and their referral to ophthalmologic examination within the "Eye-to-Eye National Campaign for Visual Disorders Prevention and Rehabilitation" (Campanha Nacional de Prevenção e Reabilitação Visual Olho no Olho); 2) To identify the teachers' perception with respect to the training received for conducting the campaign. Methods: A descriptive study has been conducted, based on data recorded from the application of a questionnaire to 1,517 elementary school teachers working in public schools in 27 Brazilian states. The following items were examined: received orientation, use of educational videos and handbooks, supplied explanations, difficulties, questions and overall campaign assessment. Results: 82.0% of the teachers stated they had received orientation and 92.0% stated they had read the "Teacher Orientation Manual", Among those who received orientation, 47.0% stated it had been supplied by school officials; 30.0%, by healthcare agents, and 23.0% by ophthalmologists. In the self-assessment of performance, 58.0% reported no difficulties; 32.0% reported questions concerning the campaign activities and the professionals who most frequently asked to provide clarification were those from the State Education Agency (38.0%), followed by the school director (20,0%), Conclusions: Most teachers considered themselves adequately trained and oriented to take part in the campaign. Teachers' training was provided by administrative officials, previously trained by ophthalmologists ("multiplying effect") and the small percentage of questions raised indicated the validity of the procedure. Concerns have been raised as to the information about the ophthalmologic examination, transportation of the children and delivery of glasses. This kind of program always presents some difficulties and requires adjustments. It should, indeed, be improved, perhaps through a closer involvement of the community and families during its development.702239245Krueguer EA. Prevenção da cegueira na infância. Planejamento.

Aspectos quantitativos e morfométricos das infrapopulações de platynosomum illiciens (trematoda: dicrocoeliidae) em paroaria dominicana (passeriformes: emberizidae) do estado da Bahia, Brasil
During the study of the metazoan parasites of Paroaria dominicana Linnaeus, 1758 (Passeriformes), four infrapopulations of Platynosomum illiciens (Brown, 1901) (Trematoda), parasitic in the liver ducts were collected, with intensity of infection 10, 11, 18 and 36 specimens respectively. Differences between the means of morphometrical values and the total number of eggs were statistically tested. The liver weigh were not significantly correlated with avian total weigh and length, and with the total parasitic abundance. Positive correlations were observed between the size of infrapopulations and the total number of eggs, and between parasite body size and the eggs. size. Negative correlations were observed between parasitic intensity and liver weigh; between the size of infrapopulations and the parasite body size; between total number and the size of eggs and between parasite body size and total number of eggs. These results suggests that host with smaller liver had greater infrapopulations. These greater infrapopulations showed smaller parasite body size and higher size and number of eggs.Durante o estudo dos metazoários parasitos de Paroaria dominicana Linnaeus, 1758 (Passeriformes), quatro infrapopulações de Platynosomum illiciens (Brown, 1901) (Trematoda) foram coletadas nos ductos hepáticos, com intensidades parasitárias de 10, 11, 18 e 36 espécimes respectivamente. Diferenças entre os valores morfométricos médios e o número total de ovos das infrapopulações foram estatisticamente testadas. O peso do fígado não se correlacionou ao peso das aves, ao comprimento do corpo das aves e à abundância parasitária. Foram detectadas correlações positivas entre o tamanho das infrapopulações e o número de ovos produzidos e entre o tamanho do corpo dos parasitos e o tamanho dos ovos. Correlações negativas foram observadas entre a intensidade parasitária e o peso do fígado; entre o tamanho das infrapopulações e o tamanho dos indivíduos dessas infrapopulações; entre o número e o tamanho dos ovos e entre o tamanho do corpo dos parasitos e o número de ovos. Os resultados indicaram que as infrapopulações maiores se estabeleceram em aves com fígados menores e que quanto maiores as infrapopulações foram observados menor tamanho corporal e menor tamanho dos ovos, os que se apresentaram em maior quantidade
Dark energy, non-minimal couplings and the origin of cosmic magnetic fields
In this work we consider the most general electromagnetic theory in curved
space-time leading to linear second order differential equations, including
non-minimal couplings to the space-time curvature. We assume the presence of a
temporal electromagnetic background whose energy density plays the role of dark
energy, as has been recently suggested. Imposing the consistency of the theory
in the weak-field limit, we show that it reduces to standard electromagnetism
in the presence of an effective electromagnetic current which is generated by
the momentum density of the matter/energy distribution, even for neutral
sources. This implies that in the presence of dark energy, the motion of
large-scale structures generates magnetic fields. Estimates of the present
amplitude of the generated seed fields for typical spiral galaxies could reach
G without any amplification. In the case of compact rotating objects,
the theory predicts their magnetic moments to be related to their angular
momenta in the way suggested by the so called Schuster-Blackett conjecture.Comment: 5 pages, no figure
Hypothalamic S1p/s1pr1 axis controls energy homeostasis
Sphingosine 1-phosphate receptor 1 (S1PR1) is a G-protein-coupled receptor for sphingosine-1-phosphate (S1P) that has a role in many physiological and pathophysiological processes. Here we show that the S1P/S1PR1 signalling pathway in hypothalamic neurons regulates energy homeostasis in rodents. We demonstrate that S1PR1 protein is highly enriched in hypothalamic POMC neurons of rats. Intracerebroventricular injections of the bioactive lipid, S1P, reduce food consumption and increase rat energy expenditure through persistent activation of STAT3 and the melanocortin system. Similarly, the selective disruption of hypothalamic S1PR1 increases food intake and reduces the respiratory exchange ratio. We further show that STAT3 controls S1PR1 expression in neurons via a positive feedback mechanism. Interestingly, several models of obesity and cancer anorexia display an imbalance of hypothalamic S1P/S1PR1/STAT3 axis, whereas pharmacological intervention ameliorates these phenotypes. Taken together, our data demonstrate that the neuronal S1P/S1PR1/STAT3 signalling axis plays a critical role in the control of energy homeostasis in rats.Sphingosine 1-phosphate receptor 1 (S1PR1) is a G-protein-coupled receptor for sphingosine-1-phosphate (S1P) that has a role in many physiological and pathophysiological processes.

Optimization of germination and initial quality of seedlings of Prunus persica tree rootstocks
In vivo assessment of possible probiotic properties of Zymomonas mobilis in a Wistar rat model
In recent years the incorporation of probiotic bacteria into foods has
received increasing scientific interest for health promotion and
disease prevention. The safety and probiotic properties of Zymomonas
mobilis CP4 (UFPEDA-202) was studied in a Wistar rat model fed the
109 colony forming units (cfu)/mL-1 of the assayed strain for 30 days.
No abnormal clinical signs were noted in the group receiving viable
cells of Z. mobilis and water (control) during the period of the
experiment. There were no significant difference (p > 0.05) in feed
intake and weight gain among mice fed the Z. mobilis in comparison to
the control group. No bacteria were found in blood, liver and spleen of
any animals. Mice receiving Z. mobilis showed significantly differences
(p < 0.05) in total and differential leucocytes count, excepting for
neutrophils, after the experimental period. Otherwise, it was not found
in control group. Histological examination showed that feeding mice
with Z. mobilis caused no signs of adverse effects on gut, liver and
spleen. From these results, Z. mobilis CP4 (UFEPEDA-202) is likely to
be nonpathogenic and safe for consumption, and could have a slight
modulating effect on immunological performance in mice
