IL-10 producing CD8+ T cells in human infection with Leishmania guyanensis.

Cytokines are increasingly recognized as important components of the cellular immune responses to intracellular pathogens. In this study, we analyzed the production of TGF-beta, IL-10 and IFN-gamma by PBMC of unexposed naïve subjects and LCL patients after stimulation with live Leishmania guyanensis (L.g.). We demonstrated that IFN-gamma is produced in controls and LCL patients, IL-10 only in LCL patients and TGF-beta only in naïve subjects. Furthermore, in naive subjects, neutralization of TGF-beta induced IL-10 production. IL-10 produced in naïve subjects when TGF-beta is neutralized or in LCL patients did not modify the IFN-gamma production but inhibit reactive nitrogen species production. Analysis of the phenotype of IL-10 producing cells in naive subjects when TGF-beta is neutralized clearly showed that they are memory CD45RA- CD8+ T cells. In LCL patients, IL-10 producing cells are both CD45RA- CD4 and CD8+ T cells. The role of these IL-10 producing CD8+ T cells in the development of the diseases should be carefully evaluated.

Teräsvalimon energia-analyysi

Teräksen valuprosessi kuluttaa runsaasti energiaa ja tuottaa merkittävästi lämpöä. Ylimääräinen lämpö on poistettava tuotantotiloista, sillä se sisältää yleensä myös paljon hiukkasia ja muita epäpuhtauksia. Lämmön talteenottaminen vähentää teräsvalimon energiankulutusta, mutta sen toteuttaminen ei ole ongelmatonta. Energia-analyysi selvittää yrityksen energian käytön ja tuotannon kehityksen sekä nykytilan. Analyysi pyrkii selvittämään kohteet, joissa energiaakuluu ja joissa sitä syntyy eniten. Tämä opinnäytetyö on sovellettu teollisuuden energia-analyysi, joka sisältää ehdotuksia energian käytöntehostamismahdollisuuksista ja säästömahdollisuuksista. Ehdotuksissa esitelläänviisi tärkeimmäksi katsottua ja kahdeksan muuta energiansäästökohdetta. Näiden lisäksi on annettu seitsemän ehdotusta muista tuotantoa ja energiansäästöä tukevista toimenpiteistä.

Monitoimityöstökeskuksen kokonaistehokkuuden parantaminen kokonaisvaltaisella tuottavalla kunnossapidolla

Tämän diplomityön tavoitteena oli tutustua kokonaisvaltaisen tuottavan kunnossapidon teoriaan ja soveltaa sitä Abloy Oy Joensuun tehtaalla pilottikohteeksi valittuun koneeseen. Pilottikohteeksi oli valittu uusi Sveitsiläinen Hydromat-monitoimityöstökeskus, jonka kokonaistehokkuutta (OEE) pyrittiin parantamaan kokonaisvaltaisella tuottavalla kunnossapidolla (TPM). Työn kirjallisuusosuudessa tarkastellaan teoriatietoja, jotka liittyvät yleisesti kunnossapitoon ja tarkemmin TPM-toimintaan. Lisäksi käsitellään kunnossapidon mittareita ja tietojärjestelmiä. Työn empiirisessä osassa selvitetään, kuinka TPM-toiminta otettiin käyttöön Hydromat-monitoimityöstökeskuksen osalta. Eniten resursseja käytettiin koneen asetusaikojen lyhentämiseen. Lisäksi koneen käyttäjien itsenäiseen kunnossapitoon siirtyminen kuului työn sisältöön. Työssä on selvitetty myös uuden tuotannon seurantataulun käyttöönotto. Seurantataulusta nähdään useita tuotantotietoja kuten kokonaistehokkuus. Työn merkittävimmät tulokset osoittavat, että asetusajat ovat tällä hekellä hyvin pitkiä tavoitteisiin nähden. Asetusaikojen lyhentyminen halutulle tasolle vaatii koneen käyttäjien pitkän oppimisprosessin sekä optimaaliset toimintaolosuhteet. Lisäksi havaittiin, että uuden toimintamallin esitteleminen ja sen käyttöönotto valmistavassa teollisuudessa on vaativa prosessi.

Efeito de herbicidas na dessecação e germinação de sementes remanescentes de Lolium multiflorum L.

A trial was carried out to evaluate efficacy of different herbicides and spray volumes when sprayed to ryegrass for chemical management and control of remaining seeds. The treatments were: three formulations of glyphosate at 1080 g ha(-1) (Original Round up, Round up Transorb, WG Round Up), paraquat + diuron at 300+500 and 150+250 g ha(-1) and glufosinate ammonium at 400 and 600 g ha(-1). All treatments were used in spray volumes of 200 and 400 l ha(-1). The effectiveness of the desiccation of ryegrass plants was assessed at 1, 3, 7, 14 and 21 days after application. At the last evaluation samples were collected for dry mass production analysis, and also panicles with seeds for germination test. Glyphosate in different formulations and volumes and glufosinate ammonium at 600 g ha(-1) when sprayed with into 400 l ha(-1) provided the best controls regarding ryegrass chemical management. Treatments with gliphosate (Roundup Original) and paraquat + diuron (300 +150 g ha(-1)) in volumes of 400 and 200 L ha(-1), respectively, were the ones that showed the lowest values of dry matter, differing from the control. All the ryegrass seeds were killed by treatments with herbicides (paraquat + diuron) at 500 + 250 g ha(-1) and glufosinate-ammonium at 600 g ha(-1) when used 200 l ha(-1).

Serviço Social e Política: uma análise da participação dos assistentes sociais no Conselho Regional de Serviço Social 14ª região

This paper analyzes the political participation of Social Workers at the Social Service Regional Council Region 14th. The theoretical and methodological framework of this investigation has as its perspective the totality of social life and its determining relations within the object of study. To the production, analysis and collecting of data it was used a qualitative approach considering a bibliographical and documental research as well as a series of twelve interviews with 2005-2008 and 2008-2011 managing counselors of CRESS/RN. It was also used the data obtained from other special interviews held with the social workers in the period between 2007 and 2008. The results of this study allow and affirm the political dimension of Caseworkers and the CRESS/RN as a space of political activity with opportunities for effective and collective elaboration of strategies in order to reach the fulfillment of the ethical and professional policy of the Social Work. From a historical viewpoint, the beginning of this process is marked by the struggle for democracy, the end of military dictatorship, the establishment of the State of Human Rights. The Democratization of the so called Federal Council of Social Workers and its Regional Councils of Social Workers, CFAS / CRAS, respectively, area a result of the participation of the category in an effort to fight for democratization in Brazil. The objective of this research, so, is to understand which the socio-historical determinants are, that focus objectively and subjectively in the demobilization of social workers in CRESS Region 14th - in the contemporary and historical context. Among the results obtained we identified the ignorance of some professional workers and also of some advisors, regarding the existence and the role of the Council, as well as the commercialization of Education that compromises the quality of the professional training in its theoretical and methodological, ethical and political dimensions. According to our understanding, this shows a the presence of a non-critical professional profile based on a false reality, on the precariousness of employment contracts which undermine the political organization and submit the worker to various social exploring mechanisms such as double shift and ultimately the fragility of the management of the Regional Council -, as a consequence of the offensive capitalist system that ideologically invests to stop the political organization founded in a critical and democratic perspective. The low participation of some advisors and, in general, the category in CRESS / RN, despite its objective conditions, is a reality and it is presented to us as a challenge to future managements and policy consolidation to society. Inasmuch as the category intends to guarantee the high quality of its social workers, the demands of future counselors, their skills and abilities in dealing with regulatory issues, administrative policies that pervade the everyday life of CRESS / RN are necessary

Produção científica sobre gestão do conhecimento e gestão da informação no âmbito da Ciência da Informação: uma aplicação da Lei de Bradford

Aimed to analyze the scientific literature on information management and knowledge management in the most relevant journals in the Information Science field, noting in this way then relevance and impact to this field. It is a qualitative research and analyzed the scientific literature about this subject published in journals (online access) in the Information Science area and classified as Qualis of Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), specifically those who were assessed as level 'A' and 'B', covering a total of 26 journal titles. We applied the Bradford's Law for the scientific production analysis, especially in relation to the articles distribution in terms of proximity or distance variables. We observed that the terms 'information management' and 'knowledge management' are contemporary and have been gained relevance over time. We also founded that the general rule: few produces a lot and many produces a little is true if considered the characteristics of the studied data distribution.

A pesquisa sobre o fazer pesquisa: uma análise de citação da literatura periódica em Ciência da Informação

Introduction: This paper considers that information science (IS) literature covers a diversity of thematics with low emphasis on researches about conducting research. The study analyzes the scientific production of authors who investigate about research methodology in the information science (IS) literature, and the references used to lay the foundation of the methodological issues regarding the area. It discusses the methodological and epistemological positions of the leading researchers highlighted as the most productive investigators on the subject in the country. Method: The research adopts the content analysis coupled with metric studies to contextualize the indicators related to productivity, to the types of authorship and citation analysis. The bibliographic coupling method is considered an analysis mode which analyzes concomitant citations. It develops a theoretical framework about the importance of scientific production analysis in different knowledge fields. The study investigates, from a theoretical perspective, the concepts about research methodology and the complementarity between methodology and epistemology in conducting research. Results: The results of the analysis showed that the production of the highlighted authors presents the methodology as a thematic focus to be applied to IS contexts, as well as a research object in the field. The prominent productivity of the authors is justified especially by deepening the meta studies about the ways to conduct research in IS. This study also identifies a trend to single-authored studies about the theme. Conclusions: The research considers that meta studies and applied and methodological studies are important to recognize a consistent theoretical and practical core in the IS area. Regarding the epistemological influences identified by the citation analysis, the study observes that the critical rationalist epistemology and the social and political epistemology are highlighted in the construction of the theoretical framework of the most productive authors.

Comparative study over methods developed for quantification of darunavir in tablets by environmental friendly infrared and capillary electrophoretic techniques

Darunavir, a protease inhibitor used in the treatment of HIV infection, presents few methods for its determination in pharmaceuticals. Infrared (IR) spectroscopy offers the possibility of obtaining spectra relatively quickly, providing interesting information, analytically, qualitatively or quantitatively. Capillary electrophoresis (CE) performs separations of high efficiency in shorter time with reagents and samples in small quantity. These two methods are cost-benefitted when we evaluate the green level and the cost of analysis. Faster and cheaper methods without generating organic waste by IR and CE for the quantification of darunavir were developed and validated, focusing socioeconomic impact of analytical decisions. If the cost of acquisition, maintenance, production, analysis and conditioning of drugs and pharmaceuticals is high, consequently the price of this product in the market will be higher and it cannot be accessible to the patient. Treatment failure not only affects the quality of life of patients, but also contributes significantly to the economic burden of the health system. In this context there is a tool called Analysis of the Life Cycle, which comes to make us think in a multidimensional way focusing the whole, the parts and especially the interaction among the parts of a system.
