Assessing intermittent saline inflows in urban water systems.

Urban water drainage systems' primary function is to transport sanitary or stormwater. The intrusion of saline waters has recognized detrimental effects. Especially in coastal areas, saline inflows can compromise performance by increasing the risk of untreated discharges, weakening the structural condition of concrete or metallic components, reducing the effectiveness of wastewater treatment processes and limiting the potential reuse for irrigation. Performance deterioration can be prevented by an early assessment of exposure to saline water, followed by timely actions to control its causes and consequences. The paper describes a procedure for diagnosing undue saline inflows. The procedure is based on the determination of saline inflow's magnitude, acceptance levels, and contribution to the system's performance. Contextual factors and performance indicators, and their reference values, are selected for the assessment. Options to address the problem are proposed, depending on the results. These options can relate to organizational, operational, and structural actions. Application to a case study allowed to validate the method and discuss the results. Here, saline volumes entering the system are quite relevant (almost 30%), posing problems regarding corrosion, treatment plant operation and significant concrete exposure to intermittent saline waters.

Ectoparasites infesting animals living in close contact with human beings: a real trouble for One Health perspective? / [Ectoparasitos infestando animais que vivem em contato próximo com seres humanos: um problema real para a perspectiva Saúde Única?]

The number of domestic animals living with human beings is rapidly increasing in parallel with an enhanced risk of transmission of their parasites and the pathogens they might carry. The aim of this study was to assess the occurrence of hematophagous arthropods infesting domestic animals from Northeastern Brazil and to remark the implications of their occurrence on the epidemiology and control of selected veterinary and human diseases. From January 2017 to April 2019, ectoparasites infesting domestic cats, dogs and horses were collected for their respective hosts and identified. Overall, ectoparasites were sampled from 86 domestic animals, living in different anthropic settings. A total of 401 specimens (344 ticks and 57 fleas) were collected from different hosts [i.e., 10 (2.49%), 96 (23.94%) and 295 (73.57%) from cats, dogs and horses, respectively]. Two flea (i.e., Ctenocephalides canis and Ctenocephalides felis) and 5 tick species (i.e., Amblyomma ovale, Amblyomma sculptum, Dermacentor nitens, Rhipicephalus microplus and Rhipicephalus sanguineus sensu lato) were identified. This study provides data on the ectoparasite fauna infesting domestic animals from Northeastern Brazil. The diagnosis and treatment of these parasites should not be underestimated, considering the role that hematophagous arthropods display as vectors of pathogens of medical and veterinary concern.(AU)

O número de animais domésticos infestados por ectoparasitos vivendo em estreito contato com seres humanos está aumentando, elevando o risco de infecção pelos patógenos transmitidos por vetores. Objetivou-se neste estudo avaliar a ocorrência de ectoparasitos infestando animais do nordeste do Brasil e discutir as implicações desse parasitismo na epidemiologia e no controle de doenças de importância médico-veterinária. De janeiro de 2017 a abril de 2019, artrópodes foram coletados de gatos, cães e cavalos, e identificados morfologicamente. Ectoparasitos foram removidos de 86 animais infestados provenientes de áreas urbanas e rurais. Foram identificados 401 espécimes (344 carrapatos e 57 pulgas) coletados de diferentes hospedeiros (10 (2,49%), 96 (23,94%) e 295 (73,57%) de gatos, cães e cavalos, respectivamente. Duas espécies de pulgas (Ctenocephalides canis e Ctenocephalides felis) e cinco espécies de carrapatos (Amblyomma ovale, Amblyomma sculptum, Dermacentornitens, Rhipicephalus microplus e Rhipicephalus sanguineus sensu lato) foram identificadas. Este estudo fornece informações sobre a ectofauna de animais domésticos do nordeste do Brasil. Portanto, o diagnóstico e o tratamento desses parasitos não devem ser subestimados, considerando que os artrópodes aqui relatados podem veicular patógenos de importância médico-veterinária.(AU)

Innovation results of IAM planning in urban water services.

The requirement to provide urban water services continuously while infrastructures are ageing, imposes the need for increasingly sustainable infrastructure asset management (IAM). To achieve and maintain adequate levels of service, the AWARE-P IAM methodology has been applied in collaborative projects launched by the National Civil Engineering Laboratory, in partnership with IST (Technical University of Lisbon), Addition (software company) and several water utilities. The objective of these projects is to support urban water utilities in the development, implementation and maintenance of IAM plans. To guarantee the success of IAM planning, following the AWARE-P IAM methodology, utilities are required to: consider that the infrastructure has system behaviour and lifespan is indefinite and guarantee the full-alignment of IAM planning with organisation objectives. By analysing the strategic and tactical plans of participating utilities, the proposed methodology principles are discussed and supported. The main innovation results from the implementation of IAM planning are also presented and discussed, including the challenges of setting up an IAM process, together with the major benefits and drawbacks that come up when developing IAM plans. The results were demonstrated by the effective implementation of 16 strategic and 14 tactical IAM plans by the participating utilities.

[Knowledge of male college students on induced abortion]. / Conhecimento de universitários do sexo masculino sobre aborto provocado.

The purpose of the study was to verify the knowledge of male university students regarding induced abortion. The sample was comprised of 71 male students that corresponded to 70% of the population made up of students from different health related programs at a federal university. Data was collected in August and October of 1998, by means of a questionnaire that was based on two previous exploratory studies. The respondents were 17 to 22 years old, catholic, single and financially dependent. The results demonstrated that a large percentage of male students had knowledge of what an induced abortion was and of its consequences, as well as of the methods used to induce the fetal loss. The respondents expressed a negative opinion about abortion and placed the responsibility for such a decision on the couple. They also indicated that besides the woman, other individuals, such as friends and family members bared some responsibility for the decision to end or not a pregnancy.

[Ethical behavior of nurses in university hospitals]. / O comportamento ético dos enfermeiros dos hospitais universitários.

The aims of this study were to analyse the conception of ethics in the nurse's speech and practice, to verify its influence on nurses formation, and to investigate the nurses views regarding to the contribution of ethics to the comprehension of the moral reality and to the critical analysis of the nursing practice. The methodology focused on the qualitative analyses of data collected through the techniques of: document collection and analysis, group interviews, and observations of the nurses ethical behaviour during their practice. According to he results, the nurses conception of ethics relates in satisfaction to their work, to professional discrimination, and to corporate issues of health team. No reference was made to citizenship concerns. There is also a setting away from ethics understanding while moral behaviour and a critical view of the profession and of health care.

[Are the roles of the nurse specialist and the master of health services the same?]. / O papel do enfermeiro especialista e do mestre nos serviços de saúde é o mesmo?

This study aimed at identifying the role of the nurse with a graduate degree at the service level based on nurses and service directors expectations in health care institutions. A total of 278 nurses and 25 service directors responded to a questionnaire and an instrument was designed to measure their expectations towards the nurse with a postgraduation degree. The results indicate that nurses and service directors hope nurses with a postgraduation degree to be highly qualified to provide care. While service directors express a slight difference in favor of both the master degree and the deep knowledge of the specialty, nurses expectations in relation to it, are a little greater in all aspects. Service directors priorize refresh courses for nurses while nurses priorize specialization courses. The study has implications for a deeper discussion of these professionals functions in service and for the objective of postgraduate education programs in the region.

[Perspective evaluation of the post-graduate courses of the Nursing Department at UFRN (1980-1992)]. / Avaliaçäo e perspectiva dos cursos de pós-graduaçäo lato-sensu do departamento de enfermagem da UFRN (1980-1992).

The purpose of the study was to evaluate the "lato sensu" graduate programs of study of the Department of Nursing in the UFRN, and to know the perspectives of its students and faculty. A total of 67 questionnaires were applied to 14 professors and 53 ex-students. The sources of data were: a survey of the scientific knowledge produced by the faculty; specialization program final reports; partial 1989-1991 program evaluations; and, the final report of the first Graduate Program Evaluation Seminar (1992). Eventhough the results of the evaluation were positive, some aspects of the program were found to need further analysis so that future graduate studies might be improved. These aspects were: revision of the curriculum content, improvement of the space environment, and improvement of the bibliographic resources.
