DRIS na avalia??o do estado nutricional do arroz irrigado por inunda??o
Guindani, Raquel Hermann P?tter;Anghinoni, Ibanor;Nachtigall, Gilmar Ribeiro;
Revista Brasileira de Ciência do Solo , 2009, DOI: 10.1590/S0100-06832009000100012
Abstract: in view of the high cost of fertilizers and the importance of mineral nutrition on the technology level used by rice producers for yields in southern brazil, the use of evaluation techniques of the nutritional status, such as foliar diagnosis has become essential. among the methods for nutritional plant diagnosis, the diagnosis and recommendation integrated system (dris) stands out, which is based on the concept of nutrient balance. the objective of this study was to establish a dris reference norm and nutritional standards for flooded rice. results of foliar analysis and grain yield of 356 farms in different rice-producing regions in the 2005/2006 growing season were used. the leaf samples were collected at the flowering stage. high-yielding populations were selected based on the best correlation between the index of nutritional balance (ibn) and the maximum yield, which reached a more than 9.000 kg ha-1. the calculation of the dris functions and indexes was based on the original method of beaufils. results indicated that: the nutrient concentration was positively related with the respective dris indexes; the ibn correlated negatively with yield; the determination of the dris equilibrium point allowed the establishment of nutritional standards for flooded rice; and the dris method, using specific norms for the rio grande do sul state, was efficient for a nutritional diagnosis of flooded rice.
Maria Gabriela Llansol Meets George Steiner: The Idea of Europe as a Llansolian Edenic Space
Ribeiro, Raquel
Ellipsis , 2008,
Abstract: This article stresses how the first two and widely ignored books of the Portuguese Maria Gabriela Llansol, Pregos na Erva and Depois dos Pregos na Erva, are the primordial traces of Llansol’s Edenic Space. Furthermore, it is stated that this Llansolian concept ultimately meets the five key ideas that define Europe according to George Steiner’s latest book, The Ideia of Europe.
Hyperbolicity and Types of Shadowing for C1 Generic Vector Fields
Raquel Ribeiro
Mathematics , 2013,
Abstract: We study various types of shadowing properties and their implication for C1 generic vector fields. We show that, generically, any of the following three hypotheses implies that an isolated set is topologically transitive and hyperbolic: (i) the set is chain transitive and satisfies the (classical) shadowing property, (ii) the set satisfies the limit shadowing property, or (iii) the set satisfies the (asymptotic) shadowing property with the additional hypothesis that stable and unstable manifolds of any pair of critical orbits intersect each other. In our proof we essentially rely on the property of chain transitivity and, in particular, show that it is implied by the limit shadowing property. We also apply our results to divergence-free vector fields.
Sobre palavras que vendem coisas: o glossário do risco em anúncios de revistas
Spink, Mary Jane P.;Galindo, Dolores;Ribeiro, Raquel Noel;Ornellas, Maria Annita;
Estudos de Psicologia (Natal) , 2007, DOI: 10.1590/S1413-294X2007000100002
Abstract: the aim of this research was to understand how the discursive traditions (risk as danger; risk as probability and risk as adventure) of the language of risk are used in magazine advertisements. advertisements were defined as genres of discourse that put into circulation materiality (quotidian artifacts) that can be commercialized (as symbolic goods) and are necessarily addressed to a specific public. a sample of 101 magazines was defined using the categories of the anuário de mídia - revistas. the analysis took into account the words used in the advertisements, the category of goods been advertised and the type of magazine in which they appeared. although risk does sell products, the focus tends to be on risk control rather than on an apology of risk. even when products are associated to risk as adventure, what is being sold is the sensation of risk counterbalanced by a diversity of safety strategies.

Abstract: OBJECTIVE: Detect of cardiac alterations in children with AIDS and compare their evolution with the administration of only one anti-retroviral and the recent cases who received drugs in combination. METHODS: We prospectively studied 47 children in 3 groups: group 1, 20 cases treated only with zidovudine; group 2, 10 patients treated initially with zidovudine and later with a combination of drugs and in group 3, 17 patients, who receiced two or three since the beginning. In all patients it was done chest X-ray, EKG and echocardiography every 6 months and after death complete pathological study. RESULTS: Among the 45 patients cases 26 (57%) were index cases. Malnutrition, diarrhea tachycardia, signs of congestive heart failure, pericardial effusion, abnormal ventricular repolarization and arrhythmias were more frequent in group 1. Echocardiographic abnormalities were present in 10 (50%) children of group 1. They were less frequent in the others two groups. In regard to the outcome in group 1, two patients had worsening of sings of cardiomyopaty and 4 died. Cardiac dysfunction in all cases of group 2 and 3 improved with the medication. CONCLUSION:- The children who received combination and their cardiac alterations had more favorable outcome than those who received only one drug.
Ancoragens e varia??es nas representa??es sociais da corrup??o
Poeschl,Gabrielle; Ribeiro,Raquel;
Análise Social , 2010,
Abstract: in this paper, we examine the representations of corruption of portuguese respondents and attempt to identify variations according to different social groups and to the general, global, or national contexts in which the phenomenon is considered. we found that ?corruption, in general?, is represented by practices and motives that reflect a moral judgment, and by illegal groups and activities, as is also the case for corruption at the global level. corruption at the global level also has a geopolitical dimension, whereas corruption at the national level is seen in a particularized way, highlighting cases and situations often debated in the media.
Revisitando as influências das agências internacionais na origem dos conselhos de políticas públicas

Servi?o Social & Sociedade , 2012, DOI: 10.1590/S0101-66282012000100004
Abstract: this article aims at deepening the debate on the influence of international agencies in the processes that gave rise to the councils of public policies as institutional channels of participation in brazil. it focuses on the intense international activity at the end of world war ii and the creation of multilateral institutions. it contemplates the international agencies'role in the field of health policies in brazil, and it seeks to reconstruct the guidelines that focused on the stimulation of participatory strategies that led to the creation of health councils, which were the first reference for other areas to implement their decentralized and participatory systems.
Metabolic Syndrome in Schizophrenia: A Non systematic Review
Marta Nascimento,Raquel Ribeiro
PsiLogos , 2012,
Abstract: Background: The link between mental illness and metabolic disturbances has been recognized since the beginning of the last century. The debate concerning medical morbidity in schizophrenia intensified during the last twenty years, especially after the introduction of atypical antipsychotics. Aims: To highlight some features of the metabolic syndrome in this population, specifically epidemiological data, underlying mechanisms and antipsychotic therapy. Methods: Non systematic review of literature. Results and Conclusions: Despite the different criteria used for the definition of metabolic syndrome, it is clear today that the schizophrenic population has the highest rate of metabolic syndrome. Additionally, the prevalence of the metabolic syndrome in this population demonstrates a geographical distribution similar to the general population. Although it hasn’t been recognized for years, schizophrenic patients’ vulnerability to develop metabolic disturbances isn’t entirely related to antipsychotic therapy. Actually, it results from an interaction of multiple factors, including hereditary, genetic, biochemical and environmental ones (which include antipsychotic therapy). Moreover, they are not exclusively explained by weight gain. Metabolic disturbances are one of the main concerns related to general psychopharmacology. The differences between typical and atypical antipsychotics in terms of metabolic syndrome are not completely established. However, clozapine and olanzapine are recognized to have the worst metabolic profile, amongst all atypical antipsychotics.
Efectos del conocimiento know-how en la subjetivación contemporánea Effects of know-how knowledge in contemporary subjectivization
Raquel Ribeiro Toral
Psicoperspectivas : Individuo y Sociedad , 2008,
Abstract: El presente artículo se propone contribuir al estudio de la subjetivación en nuestros días, considerando que la gran expansión del conocimiento know how en la organización de la vida social, está modificando el modo en que la gente usa cotidianamente su juicio y sentido común. Para una mejor comprensión, el artículo fue organizado así: introduce la conceptualización psicoanalítica freudiana respecto a la subjetivación, destacando la importancia del conocimiento subjetivante y de la función psicológica del juicio; muestra cómo a partir de la modernidad el know how comenzó a desplazar al subjetivante; integra a la discusión la perspectiva de filósofos contemporáneos que dan cuenta de dificultades en la subjetivación actual; y concluye con la idea de que el actual orden mundial basado en el know how estaría dificultando la subjetivación tal como la conocemos hasta ahora y quizá estaría dando pauta para subjetivarnos de formas novedosas. The present article intends to make a contribution to the study of subjectivization in our days, considering that the vast expansion of know-how knowledge, in social life organization, is modifying the way in which people use their judgment and common sense in every day life. For a better understanding, this article has been organized in the following way: it starts by introducingthe Freudian psychoanalytic conceptualization with regard to subjectivization, stressing the importance of subjectivating knowledge and judgment’s psychological function; it shows as well how, since modern times, this know-how began to displace the subjectivating knowledge; it proceeds by integrating to this discussion the perspective of contemporary philosophers who convey the difficulties found in current subjectivization. Finally, it concludes with the idea that the current world order, based on know-how knowledge, would be hampering subjectivization such as we conceptualize it so far, and would perhaps be giving guideline to new forms of subjectivization.

Análise Social , 2010,
Abstract: Examinam-se neste artigo as representa es da corrup o de inquiridos portugueses e procuram-se identificar varia es consoante os grupos sociais e os contextos geral, global ou nacional em que o fenómeno é considerado. Verificou-se que a “corrup o em geral” é representada por práticas e motivos que reflectem um julgamento moral e por grupos e actividades ilegais, tal como acontece em rela o à corrup o ao nível global. Esta tem ainda uma dimens o geopolítica, enquanto a corrup o ao nível nacional é entendida de forma particularizada, real ando-se casos e situa es específicas muitas vezes divulgados pelos media. In this paper, we examine the representations of corruption of Portuguese respondents and attempt to identify variations according to different social groups and to the general, global, or national contexts in which the phenomenon is considered. We found that “corruption, in general”, is represented by practices and motives that reflect a moral judgment, and by illegal groups and activities, as is also the case for corruption at the global level. Corruption at the global level also has a geopolitical dimension, whereas corruption at the national level is seen in a particularized way, highlighting cases and situations often debated in the media.
