Avan?os metodológicos na avalia??o da qualidade da forragem conservada
Jobim, Clóves Cabreira;Nussio, Luiz Gustavo;Reis, Ricardo Andrade;Schmidt, Patrick;
Revista Brasileira de Zootecnia , 2007, DOI: 10.1590/S1516-35982007001000013
Abstract: the suitable evaluation of nutritional value of forages depends on the adoption of appropriate methodologies. forage quality is highly dependent of fermentation products, in case of silage, and the losses of soluble compounds and microorganisms activity in the case of hay. the theme "methodological advances in evaluation of preserved forage quality" at the 44th annual meeting of brazilian society of animal science has as main goals to highlight the more useful and particular methodological procedures for conserved forages and additional to the standard chemical analysis.. analytical procedures for preserved forage should suffer a standardization to permit comparisons of results obtained by the world wide laboratories. this review brings to discussion the description and systematization of important physical and chemical methods to be implemented in preserved forage evaluation. the methodological procedures available permit not only quantify, but also permit qualify the losses occurred during preservation process and across the aerobic exposition of the roughage source during feed out. it suggests that the adoption of any management strategies for conserved forages may depend on an evaluation accordingly fit to the losses observed in the overall process.
From manifolds to invariants of E_n-algebras
Ricardo Andrade
Mathematics , 2012,
Abstract: This thesis represents the first step in an investigation of an interesting class of manifold-theoretic invariants of $E_n$-algebras which generalize topological Hochschild homology. The main goal of this thesis is to give a definition of the invariants, and analyse their geometric framework. These invariants have appeared in the work of Paolo Salvatore and Jacob Lurie (who calls them topological chiral homology), where they are involved in a sort of non-abelian Poincar\'e duality.

A new species of Bruchomyia (Diptera: Psychodidae) from caverns in the state of Minas Gerais, Brazil
Freddy Bravo,Ricardo Andrade Barata
Zoologia (Curitiba) , 2012, DOI: 10.1590/s1984-46702012000500009
Abstract: Nine Neotropical species of Bruchomyia Alexander, 1920 have been previously described, all from South America. A new species of this rare genus, collected in caverns of the state of Minas Gerais, southeastern Brazil, is described and named Bruchomyia mineira sp. nov. The new species is morphologically similar to B. argentina Alexander, 1920, but they can be differentiated from each other by characters of the eyes, M2 vein and base of gonostylus.
Influências das condi??es e organiza??o do trabalho de uma indústria de transforma??o de cana-de-a?úcar na ocorrência de acidentes de trabalho
Rumin, Cassiano Ricardo;Schmidt, Maria Luiza Gava;
Saúde e Sociedade , 2008, DOI: 10.1590/S0104-12902008000400007
Abstract: the present study is about the relationship between the work conditions and organization as elements that contribute to work accidents. the data were collected in a sugar cane industry that produces sugar, alcohol and other derivates located in the state of s?o paulo. for data collection we have used direct observation of work and conducted semi-directed personal interviews with 22 workers from the sugar production division. sugar production was indicated by the work safety and hygienic team as the section where most accidents occurred. we have used the psychodynamics of the work view (dejours, 1994) as the theoretical framework to assess data obtained in the interview because it highlights the role the men-work relationship plays in the physical and psychological health of workers. the interviews analysis involved three aspects: working conditions, working organization and dissatisfaction. results showed that the studied environment presents physical, chemical and biological factors that are unfavorable to workers' health. as for the working organization, data showed that the working division, as well as the tasks overloaded workers. reports on dissatisfaction involved: lack of perspective of professional development, lack of technical training, difficulty in dealing with equipment and inappropriate protection equipment. in the workers' speech one can stand out the inefficiency of the organizational actions to eliminate or neutralize the working accident's risks and the prevalence of the "unsafe act" theory in the investigation of the working accidents' cause.
Bayesian GARMA Models for Count Data
Marinho G. Andrade,Ricardo S. Ehlers,Breno S. Andrade
Statistics , 2015,
Abstract: Generalized autoregressive moving average (GARMA) models are a class of models that was developed for extending the univariate Gaussian ARMA time series model to a flexible observation-driven model for non-Gaussian time series data. This work presents Bayesian approach for GARMA models with Poisson, binomial and negative binomial distributions. A simulation study was carried out to investigate the performance of Bayesian estimation and Bayesian model selection criteria. Also three real datasets were analysed using the Bayesian approach on GARMA models.
Effects of Socioeconomic on Survival for Adult Glioblastoma Multiform Patients in Rio de Janeiro, Brazil, 1999-2009  [PDF]
Jose Carlos Lynch, Leonardo Welling, Claudia Escosteguy, Alessandra G. L. Pereira, Ricardo Andrade, Celestino Pereira
Open Journal of Modern Neurosurgery (OJMN) , 2012, DOI: 10.4236/ojmn.2012.21001
Abstract: Backgrond: To compare the survival of glioblastoma multiforme (GBM) patients operated on at public hospital with that of patients operated on at the private hospital. Method: We carried out a retrospective analysis of the patients’ medical records, the surgical reports, and the pre and post-operative images of patients with a histopathological confirmed adult supratentorial glioblastoma multiform (GBM). Sixty-three patients were treated at public hospital and 21 at private hospitals. Results: The present study revealed that the survival of patients treated in private hospitals was statistically superior to that of patients treated in public hospitals (11.9 vs 7.7). Conclusions: Our study advances towards the confirmation of the hypothesis that socioeconomic and educational factors influence the KPS and the performance of RT treatment, with negative effects over the GBM patients’ survival.
Tetramethrin Identified in Fat Adjacent to Mammary Carcinoma in a Male Dog—Case Report  [PDF]
Fernanda C. Figueiroa, Paulo Ricardo O. Bersano, Fábio Henrique E. Andrade, Noeme S. Rocha
Open Journal of Pathology (OJPathology) , 2012, DOI: 10.4236/ojpathology.2012.23019
Abstract: Canine mammary tumors (CMT) are very common in female dogs, representing approximately 50% of all tumors in this species, but are highly uncommon in male dogs and are primarily related to hyperestrogenism. There is considerable scientific interest in the possible role of environmental contaminants in the etiology of mammary tumors, specifically in relation to synthetic chemical substances released into the environment to which living beings are either directly or indirectly exposed. In this study, the presence of pyrethroid insecticide was observed in adipose tissue adjacent to canine mammary tumors. High Precision Liquid Chromatography—HPLC was adapted to detect and identify environmental contaminants in adipose tissue adjacent to malignant mammary tumor in one male dog, Akita, 12 years old. After surgery, the mass was carefully examined for malignant neoplastic lesions. Five grams of adipose tissue adjacent to the tumor was collected to detect environmental contaminants. The pyrethroid was identified as tetramethrin, at 0.20 μg/g. This is the first report in which the environmental contaminant level was detectable in adipose tissue of this male dog with a malignant mammary tumor, by HPLC. Results suggest the possible involvement of pyrethroid in the canine mammary tumor carcinogenesis since this animal did not present any other tumor that could cause hyperestrogenism.
VARIACIONES DEL CONTENIDO DE Mn DE DOS SUELOS SOMETIDOS A ESTERILIZACIóN Y SU EFECTO SOBRE LA PUDRICION RADICAL DEL TRIGO O "MAL DE PIE"

Abstract: the variation on mn content of a suppressive and a conducive soils on the expression of take-all wheat (triticum aestivum l.) disease, caused by the fungus gaeumannomyces graminis (sacc.) von arx & olivier var. tritici walker (ggt), was evaluated under controlled greenhouse conditions. two soils of the ninth region previously determined to be a) naturally suppressive (ultisol) and b) as conducive (andisol) to wheat take-all disease were used. both soils were seeded with wheat cv. dalcahue - inia for 40 days, under natural growing conditions and in autoclave and microwave sterilized soil, to observe the effect of mn content on the expression of the disease. the mn content increased after sterilization from 98.2 mg kg-1 to 293 mg kg-1 in the suppressive soil, and from 2.5 mg kg-1 to 295 mg kg-1 in the conducive soil. the dry matter was not affected by the mn variations in the soils. the root infection process of the wheat operated independently of the available mn content of the soil, be it suppressive or conducive; and the root infection reached levels as high as 89%. the foregoing indicates that the inhibition of the infection observed on transferring 1% of the suppressive soil to a sterile base is not an expression of their manganese content but of biological factors associated with those soils.
