Developing and implementing an open and non-proprietary device description for FOUNDATION fieldbus based on software standards

Support for interoperability and interchangeability of software components which are part of a fieldbus automation system relies on the definition of open architectures, most of them involving proprietary technologies. Concurrently, standard, open and non-proprietary technologies, such as XML, SOAP, Web Services and the like, have greatly evolved and been diffused in the computing area. This article presents a FOUNDATION fieldbus (TM) device description technology named Open-EDD, based on XML and other related technologies (XLST, DOM using Xerces implementation, OO, XMIL Schema), proposing an open and nonproprietary alternative to the EDD (Electronic Device Description). This initial proposal includes defining Open-EDDML as the programming language of the technology in the FOUNDATION fieldbus (TM) protocol, implementing a compiler and a parser, and finally, integrating and testing the new technology using field devices and a commercial fieldbus configurator. This study attests that this new technology is feasible and can be applied to other configurators or HMI applications used in fieldbus automation systems. (c) 2008 Elsevier B.V. All rights reserved.

Acidity and Aluminum Speciation as Affected by Surface Liming in Tropical No-Till Soils

Aluminum toxicity is one of the major soil factors limiting root growth in acidic soils. Because of the increase in organic matter content in the upper few centimeters of soils under no-till systems (NTS), most Al in soil solution may be complexed to dissolved organic C (DOC), thus decreasing its bioavailability. The aim of this study was to evaluate the effects of surface liming on Al speciation in soil solution in Brazilian sites under NTS. Field experiments were performed in two regions with contrasting climates and levels of soil acidity: Rondonopolis, Mato Grosso State, on a Rhodic Haplustox, and Ponta Grossa, Parana State, on a Typic Hapludox. The treatments consisted of a control and three lime rates, surface applied to raise the base saturation to 50, 70, and 90%. Soil solution was obtained at soil water equilibrium (1:1 w/w soil/water ratio). The effects of surface liming on soil chemical attributes and on the composition of the soil solution were dependent on weather conditions, time under NTS, and soil weathering. Most Al in soil solution was complexed to DOC, representing about 70 to 80% of the total Al at pH <5.0, and about 30 to 4096 at pH >5.0. Under pH 5.5, the results were closely correlated with the solubility line for amorphous Al. Organic complexes may control Al(3+) release into soil solution at pH <5.5. Results suggest that in areas under NTS for a long period of time, Al toxicity might decrease due to its complexation to high-molecular-weight organic compounds.

Reclaimed wastewater: Impact on soil-plant system under tropical conditions

This study investigated the ionic speciation of reclaimed urban wastewater (RWW), and the impact of increasing RWW irrigation rates on soil properties and plant nutrition under field conditions. Most RWW elements (>66%) are readily available as NH(4)(+), Ca(2+), Mg(2+), K(+), SO(4)(2-), Cl(-), H(3)BO(3), Mn(2+) and Zn(2+), but in imbalanced proportion for plant nutrition. Lead, Cd, Cr and Al in RWW are mostly bounded with DOM or OH. Irrigation with RWW decreased soil acidity, which is beneficial to the acidic tropical soil. Although RWW irrigation builds exchangeable Na(+) up, the excessive Na(+) was leached out of the soil profile after a rainy summer season (>400 mm). Benefits of the disposal of RWW to the soil under tropical conditions were discussed, however, the over irrigation with RWW (>100% of crop evapotranspiration) led to a nutritional imbalance, accumulating S and leading to a plant deficiency of P and K.

Mass Spectrometric Analysis of a Cyclic 7,8-Butanoguanine Adduct of N-Nitrosopyrrolidine: Comparison to Other N-Nitrosopyrrolidine Adducts in Rat Hepatic DNA

The well established rat hepatocarcinogen N-nitrosopytrolidine (NPYR, 1) requires metabolic activation to DNA adducts to express its carcinogenic activity. Among the NPYR-DNA adducts that have been identified, the cyclic 7,8-butanoguanine adduct 2-amino-6,7,8,9-tetrahydro-9-hydroxypyrido[2,1-f]purine-4(3H)-one (6) has been quantified using moderately sensitive methods, but its levels have never been compared to those of other DNA adducts of NPYR in rat hepatic DNA. Therefore, in this study, we developed a sensitive new LC-ESI-MS/MS-SRM method for the quantitation of adduct 6 and compared its levels to those of several other NPYR-DNA adducts formed by different mechanisms. The new method was shown to be accurate and precise, with good recoveries and low fmol detection limits. Rats were treated with NPYR by gavage at doses of 46, 92, or 184 mg/kg body weight and sacrificed 16 h later. Hepatic DNA was isolated and analyzed for NPYR-DNA adducts. Adduct 6 was by far the most prevalent, with levels ranging from about 900-3000 mu mol/mol Gua and responsive to dose. Levels of adducts formed from crotonaldehyde, a metabolite of NPYR, were about 0.2-0.9 mu mol/mol dGuo, while those of adducts resulting from reaction with DNA of tetrahydrofuranyl-like intermediates were in the range of 0.01-4 mu mol/mol deoxyribonucleoside. The results of this study demonstrate that, among typical NPYR-DNA adducts, adduct 6 is easily the most abundant in hepatic DNA. Since previous studies have shown that it can be detected in the urine of NPYR-treated rats, the results suggest that it is a potential candidate as a biomarker for assessing human exposure to and metabolic activation of NPYR.

Population pharmacokinetics and pharmacodynamics: An underutilized resource

A meeting was convened in Canberra, Australia, at the request of the Australian Drug Evaluation Committee (ADEC), on December 3-4, 1997 to discuss the role of population pharmacokinetics and pharmacodynamics in drug evaluation and development. The ADEC was particularly concerned about registration of drugs in the pediatric age group. The population approach could be used more often than is currently the case in pharmacokinetic and pharmacodynamic studies to provide valuable information for the safe and effective use of drugs in neonates, infants, and children. The meeting ultimately broadened to include discussion about other subgroups. The main conclusions of the meeting were: 1. The population approach, pharmacokinetic and pharmacodynamic analysis, is a valuable tool both for drug registration purposes and for optimal dosing of drugs in specific groups of patients, 2. Population pharmacokinetic and pharmacodynamic studies are able to fill in the gaps' in registration of drugs, for example, to provide information on optimal pediatric dosing. Such studies provide a basis for enhancing product information to improve rational prescribing, 3. Expertise is required to perform the population studies and expertise, with a clinical perspective, is also required to evaluate such studies if they are to be submitted as part of a drug registration dossier Such expertise is available in the Australasian region and is increasing. Centers of excellence with the appropriate expertise to advise and assist should be encouraged to develop and grow in the region, 4. The use of the population approach by the pharmaceutical industry needs to be encouraged to provide valuable information not obtainable by other techniques. The acceptance of population pharmacokinetic and pharmacodynamic analyses by regulatory agencies also needs to be encouraged, and 5. Development of the population approach to pharmacokinetics and pharmacodynamics is needed from a public health perspective to ensure that all available information is collected and used to improve the way drugs are used. This important endeavor needs funding and support at the local and international levels.

Christian Thomasius and the desacralization of philosophy

Despite his significance in early modern Germany, where he was well-known as a political and moral philosopher, jurist, lay-theologian, social and educational reformer, Christian Thomasius (1655-1728) is little known in the world of Anglophone scholarship. 1 Unlike those of his mentor, Samuel Pufendorf, none of Thomasius's works was translated into English, when, at the end of the seventeenth century, English thinkers were searching for a final settlement to the religious question. None has been translated since. Moreover, while Thomasius has been subject to increasing scholarly attention in Germany since the 1970s, where he has been treated largely as a representative of the "early Enlightenment," there is very little secondary literature on him in English. 2 Things are however beginning to change in this regard, with recent research already giving rise to important new Anglophone books and essays. 3 Knud Haakonssen's article on [End Page 595] Thomasius for the new Routledge Encyclopedia of Philosophy might well be a straw in the wind

Management of Uncommon Hernias in Cirrhotic Patients

Background. Abdominal hernias are a common disease among cirrhotic patients, because of malnutrition and persistently high intra-abdominal pressure due to ascites. When tense ascites is present, life-threatening complications are likely to occur. In such cases, the morbidity and mortality rates are high. Objective. We describe 3 cirrhotic patients with rare complicated hernias that needed surgical repair. We discuss optimal timing for surgical approaches and the necessity of ascites control before surgery, as well as the technical details of the procedures. Method. Review of hospital charts of selected rare cases of herniae in cirrhotic patients. Conclusion. Elective surgical approaches can treat even uncommon hernias in cirrhotic patients with good results.

Interferon and Alternative Activation of Monocyte/Macrophages in Systemic Sclerosis-Associated Pulmonary Arterial Hypertension

Objective. To explore the relationship between biomarkers of pulmonary arterial hypertension (PAH), interferon (IFN)-regulated gene expression, and the alternative activation pathway in systemic sclerosis (SSc). Methods. Peripheral blood mononuclear cells (PBMCs) were purified from healthy controls, patients with idiopathic PAH, and SSc patients (classified as having diffuse cutaneous SSc, limited cutaneous SSc [lcSSc] without PAH, and lcSSc with PAH). IFN-regulated and ""PAH biomarker"" genes were compared after supervised hierarchical clustering. Messenger RNA levels of selected IFN-regulated genes (Siglec1 and MX1), biomarker genes (IL13RA1, CCR1, and JAK2), and the alternative activation marker gene (MRC1) were analyzed on PBMCs and on CD14- and CD14+ cell populations. Interleukin-13 (IL-13) and IL-4 concentrations were measured in plasma by immunoassay. CD14, MRC1, and IL13RA1 surface expression was analyzed by flow cytometry. Results. Increased PBMC expression of both IFN-regulated and biomarker genes distinguished SSc patients from healthy controls. Expression of genes in the biomarker cluster, but not in the IFN-regulated cluster, distinguished lcSSc with PAH from lcSSc without PAH. The genes CCR1 (P < 0.001) and JAK2 (P < 0.001) were expressed more highly in lcSSc patients with PAH compared with controls and mainly by CD14+ cells. MRC1 expression was increased exclusively in lcSSc patients with PAH (P < 0.001) and correlated strongly with pulmonary artery pressure (r = 0.52, P = 0.03) and higher mortality (P = 0.02). MRC1 expression was higher in CD14+ cells and was greatly increased by stimulation with IL-13. IL-13 concentrations in plasma were most highly increased in lcSSc patients with PAH (P < 0.001). Conclusion. IFN-regulated and biomarker genes represent distinct, although related, clusters in lcSSc patients with PAH. MRC1, a marker for the effect of IL-13 on alternative monocyte/macrophage activation, is associated with this severe complication and is related to mortality.

O combate ?? viol??ncia contra a mulher: a luta entre antigos valores e novos padr??es de pol??ticas p??blicas

O caso relata uma situa????o de viol??ncia dom??stica vivenciada por uma mulher negra e os obst??culos por ela enfrentados para denunciar o agressor e fazer valer seus direitos. Mostra a contradi????o entre normas e sua efetiva aplica????o, quando o comportamento de agentes p??blicos ainda conserva padr??es e valores de um Estado autorit??rio, patriarcal e escravocrata. O caso ?? fict??cio, mas espelha situa????es reais coletadas em documentos e relat??rios da Ouvidoria da Secretaria de Pol??ticas para as Mulheres- SPM/PR. O estudo suscita discuss??es sobre a dimens??o ??tica da atividade de agentes p??blicos de um Estado democr??tico, englobando quest??es referentes aos direitos humanos, direitos e deveres do Estado e da sociedade, o papel da transpar??ncia, do controle social e da responsabiliza????o por resultados (accountability) etc. Pode ser aplicado em cursos sobre ??tica e servi??o p??blico, pol??ticas p??blicas de g??nero e ra??a e atendimento ao cidad??o

Matriz de capacita????o modelada por compet??ncias para atuar em programas de educa????o a dist??ncia: uma proposta para as escolas de governo

This study discusses distance learning (DL) as a corporate education strategy in the scope of National Policy on Staff Development. The purpose was to identify, along with managers and specialists of National Network of Schools of Government in Brazil (RNEG), demanded competencies for DL professionals acting in continued education to service public. Part of the research is based in official documents and in related capacity-building initiatives of Schools of Government in the last three years. Through questionnaire sent to managers of institutions of RNEG, we identified existing infrastructure, teams profile, actions developed in DL and training needs. The research allowed to map the critical competencies to work in DL programs and to create a proposal from a Competency-Based Training Matrix for school teams in order to leverage continuing education programs to public servants in three spheres of government. The results revealed the key technological, pedagogical, management and communication skills, as well as the critical activities and content to be included in the training plans. It was found that 88% of institutions have already implemented or are in the process of implementing DL, and the other 12% are deficient in qualified staff to make regulations on hiring personnel or in technology fluency. This corroborates the importance and the contribution of Competency-Based Training Matrix for RNEG

Um corpo-dissertação em movimento : uma questão de aprendizagem

Este trabalho ganha corpo a partir das experiências do antropólogo Carlos Castaneda. Além de ponto de partida para pensar as questões relativas ao corpo, o movimento e aprendizagem, as obras A Erva do diabo, Uma estranha realidade e Porta para o infinito, do autor mencionado, comparecem aqui para 1) investigarmos os relatos de experiência; 2) apresentarmos alguns conceitos-chaves, relativos a aprendizagem da “feitiçaria”, tal como a vontade. Vale frisar que nosso interesse na obra de Castaneda, não está nas questões místicas do xamanismo, nem mesmo nos pontos relativos ao campo da antropologia, mas na questão da aprendizagem. Para Dom Juan, o vellho índio feiticeiro e principal mestre de Carlos Castaneda, o propósito final do aprendizado da feitiçaria é justamente tornar-se um homem de conhecimento. Com o objetivo de analisar o lugar do movimento e do corpo no processo de aprendizagem, faremos o seguinte percurso analítico: de Skinner e Piaget abordaremos respectivamente a aprendizagem do comportamento operante e a aprendizagem em sentido amplo. Em seguida, apresentamos o pensamento de Francisco Varela e Bruno Latour, principalmente os conceitos de enação, corpos articulados e aprendizagem por afetação. Com Vincianne Despret discutiremos o aspecto afectivo, corporal e involuntário da aprendizagem. Com este apanhado conceitual, visamos então colocar em análise os efeitos ético-políticos dos modos de produção de conhecimento, efeitos irremediavelmente neste corpo-dissertação, e mais ainda efeitos na vida. Por fim, ao que parece, as modulações nos conceitos de corpo, movimento/ação, ao longo da exposição dos autores indicaram, por vezes, a participação de outros elementos, tais como a vontade e a percepção-atenção, implicando variações na forma de conceber a aprendizagem. Percebemos que de acordo com a formulação de aprendizagem e as nuances do movimento/ação e do corpo, isto implica produções diferenciadas de conhecimento e de realidade.
