Helminthological records of six-banded Armadillos Euphractus sexcinctus (Linnaeus, 1758) from the Brazilian semi-arid region, Patos county, Paraiba state, including new morphological data on Trichohelix tuberculata (Parona and Stossich, 1901) Ortlepp, 1922 and proposal of Hadrostrongylus ransomi nov comb.

This work aimed to evaluate the gastrointestinal helminthfauna composition of six-banded armadillos from the Brazilian semi-arid region. Gastrointestinal contents of six road-killed adult animals from Patos County, Paraiba State, were analyzed. Six species of nematodes, comprising five genera and four families, were recovered from the analyzed animals. New morphological data on Trichohelix tuberculata is given, along with a new taxonomical proposal for Hadrostrongylus ransomi (Travassos, 1935) n. comb. This is the first record for parasitic helminths in this host from the Brazilian semi-arid.

ESTABILIDADE TERMICA DO PARACETAMOL EM SOLUCAO: CROMATOGRAFIA EM CAMADA DELGADA (CCD) - ESPECTROFOTOMETRIA ULTRAVIOLETA

The interference practised by the products in degradation of paracetemol when there is the application of spectrophotometry UV is the main obstruction to the execution of studies of thermic stability. The application of chromatography in slender layer to the isolation of paracetamol, besides being the excessively hard to apply was satisfactory to the desired proposal. The type and extension of degradation suffered by paracetamol in solution suggest the convenient inclusion, in the formulations, of one system antioxidant. This practice makes possible the blockage of the oxidation of p-aminophenol, produced by the hydrolytic degradation of paracetamol; this fact propitiated the diminution of the number of products of degradation in the medicine, making the use more secure. On the other hand, considering especially the methodological necessities of the present work, the presence of one antioxidant system facilitated the separation of paracetamol through the Thin Layer Chromatography and consequently optimized its quantification by Spectrophotometry UV during the study of thermic stability. The formulation proposed revealed excellent stability.

Trabalhando com estratégias de ensino-aprendizado por descoberta na área da saúde: a problematização e a aprendizagem baseada em problemas.

Considering the changes in teaching in the health field and the demand for new ways of dealing with knowledge in higher learning, the article discusses two innovative methodological approaches: problem-based learning (PBL) and problematization. Describing the two methods' theoretical roots, the article attempts to identify their main foundations. As distinct proposals, both contribute to a review of the teaching and learning process: problematization, focused on knowledge construction in the context of the formation of a critical awareness; PBL, focused on cognitive aspects in the construction of concepts and appropriation of basic mechanisms in science. Both problematization and PBL lead to breaks with the traditional way of teaching and learning, stimulating participatory management by actors in the experience and reorganization of the relationship between theory and practice. The critique of each proposal's possibilities and limits using the analysis of their theoretical and methodological foundations leads us to conclude that pedagogical experiences based on PBL and/or problematization can represent an innovative trend in the context of health education, fostering breaks and more sweeping changes.

Proposal of a new technique for bile duct reconstruction after iatrogenic injury. Study in dogs and review of the literature

Purpose: Interposition of a jejunal tube between the common bile duct and duodenum. Methods: Five adult mongrel dogs of both sexes, weighing on average 22.3 kg (18 to 26.5 kg), were used. Obstructive jaundice was induced by ligation of the distal common bile duct. After one week, a 2.5-cm long jejunal tube was fabricated from a segment of the loop removed 15 cm from the Treitz angle and interposed between the common bile duct and duodenum. Results: The animals presented good clinical evolution and no complications were observed. After 6 weeks, complete integration was noted between the bile duct mucosa, tube and duodenum and a significant reduction in total bilirubin and alkaline phosphatase was observed when compared to the values obtained one week after ligation of the common bile duct. Conclusion: The jejunal tube interposed between the dilated bile duct and duodenum showed good anatomic integration and reduced total bilirubin and alkaline phosphatase levels in the animals studied.

A development process proposal for the ERP5 system

Modeling ERP software means capturing the information necessary for supporting enterprise management. This modeling process goes down through different abstraction layers, from enterprise modeling to code generation. Thus ERP is the kind of system where enterprise engineering undoubtedly has, or should have, a strong influence. For the case of Free/Open Source ERP, the lack of proper modeling methods and tools can jeopardize the advantage brought by source code availability. Therefore, the aim of this paper is to present a development process proposal for the Open Source ERP5 system. The proposed development process aims to cover different abstraction levels, taking into account well established standards and common practices, as well as platform issues. Its main goal is to provide an adaptable meta-process to ERP5 adopters. © 2006 IEEE.

Proposal of a hybrid rectifier structure with HPF and low THD suitable for front-end trolleybuses systems supplied by AC distribution networks

This paper presents the development and the experimental analysis of a new single-phase hybrid rectifier structure with high power factor (PF) and low harmonic distortion of current (THDI), suitable for application in traction systems of electrical vehicles pulled by electrical motors (trolleybus), which are powered by urban distribution network. This front-end rectifier structure is capable of providing significant improvements in trolleybuses systems and in the urban distribution network costs, and efficiency. The proposed structure is composed by an ordinary single-phase diode rectifier with parallel connection of a switched converter. It is outlined that the switched converter is capable of composing the input line current waveform assuring high power factor (HPF) and low THDI, as well as ordinary front-end converter. However, the power rating of the switched converter is about 34% of the total output power, assuring robustness and reliability. Therefore, the proposed structure was named single-phase HPF hybrid rectifier. A prototype rated at 15kW was developed and analyzed in laboratory. It was found that the input line current harmonic spectrum is in accordance with the harmonic limits imposed by IEC61000-3-4. The principle of operation, the mathematical analysis, the PWM control strategy, and experimental results are also presented in this paper. © 2009 IEEE.

Strategy proposal, from the perspective of Latin America and the Caribbean, for advancing towards an international convention on the human rights of older persons

The Brasilia Declaration, adopted in 2007 at the second Regional Intergovernmental Conference on Ageing in Latin America and the Caribbean: towards a society for all ages and rights-based social protection and ratified in ECLAC resolution 644(XXXII) of 2008, called on participating governments to work towards adopting a international convention regarding the rights of older persons (Article 24). It also established a mandate for a Human Rights Council Special Rapporteur who would be responsible for promoting and protecting the rights of older persons (Article 25).Three meetings were held during the past biennium pursuant to that commitment. The first and second meetings took place, respectively, in Rio de Janeiro, Brazil (2008) and in Buenos Aires, Argentina (2009). At the third meeting, held in Santiago (Chile), on 5-6 October 2009, participating countries requested the Secretariat of the United Nations Economic Commission for Latin America (ECLAC) to prepare "a proposal for a strategy on how to follow up article 24 and 25 of the Brasilia Declaration." This proposal should include the "minimum content necessary in an international convention on the rights of older persons from the Latin American and Caribbean perspective."In response to this request, this document first presents a general overview of existing human rights standards, both at the international and at the regional levels, that are relevant to the promotion and the protection of the rights of older persons. It then provides the arguments that, from a Latin American and Caribbean perspective, justify the adoption of an international convention regarding the rights of older persons, as well as the minimum contents that this convention should include. The document finally presents a proposed strategy to move towards the adoption of an international convention in this realm from a Latin American and Caribbean perspective.

Managing environmental training in organizations: Theoretical review and proposal of a model

Purpose: The aim of this work is to address the issue of environmental training in organizations, presenting a theoretical review on the subject and proposing a model that highlights the importance of this type of training for organizations. Design/methodology/approach: The paper presents a thorough, updated literature review, discusses typology and the best practices of environmental training, and presents a framework integrating environmental training and organizational results. Findings: A careful consideration allows identifying a significant theoretical gap related to the lack of theoretical references, best practices, and an alignment between environmental training and organizational results. To overcome this gap, a model was proposed that helps to manage the environmental training process in organizations. Research limitations/implications: The paper needs to be complemented with empirical research on the topic. Originality/value: Environmental training is considered to be an essential element for organizations seeking to mitigate their environmental impacts. ISO 14001 states that environmental management is a duty of certified organizations. However, there have been few published articles that suggest models and insights to improve the environmental training in organizations. © Emerald Group Publishing Limited.
