Silva, Adriana Lara da;Costa, Rodrigo Alves;Martins, Afonso Henriques;
Rem: Revista Escola de Minas , 2002, DOI: 10.1590/S0370-44672002000200008
Abstract: this work presents the bench scale experimental results for the cyanide regeneration from pure alkaline aqueous solutions of gold, cooper and iron cyanocomplexes using the avr process associated to the ion exchange polymeric resins imac hp555sò ((room&haas-usa) and amberlite ira-420ò (room&haas brasil ltda.). the resin imac hp555sò adsorved 64.5% cn, 87.4% au, 64.9% cu and 60.5% fe from the alkaline solution containing metal cyanocomplexes. meanwhile, the elution stage with h2so4 and thiourea reached 31.2% cn, 86.2% au, 86.4% cu e 41.5% fe. the resin ira-420ò adsorbed 53.4% cn, 86.3% au, 83.8% cu and 86.0% fe under the same experimental conditions adopted for the resin imac hp555sò. the resin amberlite ira-420ò eluted 48% cn, 96.8% au, 9.1% cu and 76% fe.

Rem: Revista Escola de Minas , 2002,
Abstract: Esse trabalho apresenta os resultados da regenera o de cianetos, presentes em solu es aquosas com composi o química similar ao de efluentes típicos da cianeta o do ouro, através do processo AVR (Acidifica o, Volatiliza o, Reneutraliza o) associado ao emprego de resinas poliméricas ani nicas de troca i nica Imac HP555sò (Rohm&Haas Co.-USA) e Amberlite IRA-420ò (Room&Haas Química Ltda.-Brasil). A resina Imac HP555sò adsorveu 64,5% CN, 87,4% Au, 64,9% Cu e 60,5% Fe presentes em uma solu o alcalina mista de cianocomplexos metálicos. Na etapa de elui o com H2SO4 e tiouréia foram alcan ados 31,2% CN, 86,2% Au, 86,4% Cu e 41,5% Fe. A resina IRA-420ò, nas mesmas condi es experimentais do estudo da resina Imac HP555sò, adsorveu 53,4% CN, 86,3% Au, 83,8% Cu e 86,0% Fe. Em termos de elui o, a resina Amberlite IRA-420ò obteve 48% CN, 96,8% Au, 9,1% Cu e 76% Fe.

Revista Ceres , 2011, DOI: 10.1590/S0034-737X2011000600001
Abstract: in vitro culture offers a controlled system to study the nutritional, physiologic and biochemical processes of embryos in several developmental stages. in this work, the relationship between development stage of the fruit and sucrose concentration in the culture medium for in vitro development of coffee embryos was evaluated. embryos of coffea arabica l. cv. acaiá were excised and inoculated into the culture medium ms with ph adjusted to 5.8. the treatments consisted of the combination of six sucrose concentrations (0, 15, 30, 60, 90 and 120 g l-1) and six developmental stages of the fruit ('pin-head', 'lead', 'green', 'green-yellow', 'cherry' and 'overripe'). after inoculation, the embryos were incubated in growth room at 27 ± 1oc, photoperiod of 16 hours and 35 μ mol m-2 s-1 of luminous intensity. the experimental design was entirely randomized (6 x 6 factorial), with six repetitions and the parcel constituted by four tubes each. after 60 days, the seedlings were evaluated based on shoot length, total fresh weight of shoot and root. influences of the sucrose concentrations and the stages of fruit development were observed, and the best results were obtained with embryos excised in the stage 'green' and inoculated in the culture medium supplemented with 51 to 70 g sucrose l-1.
Revisitando a espanhola: a gripe pandêmica de 1918 no Rio de Janeiro
Goulart, Adriana da Costa;
História, Ciências, Saúde-Manguinhos , 2005, DOI: 10.1590/S0104-59702005000100006
Abstract: the article analyzes the political and social impacts of the 1918 spanish flu epidemic in the city of rio de janeiro, then brazil's federal capital. based on an analysis of rio de janeiro press reports and of other documentation (including annals, reports, and bulletins from a federal ministry, the mayor's office, and the chamber of deputies, along with studies from the brazilian national academy of medicine and dissertations from rio de janeiro's faculdade de medicina), we explore use of the epidemic as a means of political engineering. our focus is on how the epidemic impacted not only the representation of certain political and social actors but also the reaffirmation of a group of sanitarians as an intelligentsia with a vocation for political leadership who played a key role in the process of modernizing brazilian society.

Open Journal of Forestry (OJF) , 2014, DOI: 10.4236/ojf.2014.42021
Abstract:

The study aimed to establish floral composition, diversity levels, category size, phytosociological structure, commercial use and ecological group of species present in the regeneration of open ombrophile forest in southern Amazon, Brazil. Data were collected at S?o Nicolau farm, in the municipality of Cotrigua?u, northwest of Mato Grosso state, coordinates 51°9'19.5\"S and 58°14'53\"W. One hundred plots of 10 × 10 m were allocated. All individuals between 29.9 and 59.9 cm had circumference at breast height (CAP) measure, with sub-plots of 5 × 5 m which were measured in all subjects between 1:50 m in height 29.9 cm CAP and sub-plots of 2 × 2 m for individuals between 0.30 to 1.5 m tall. The information obtained in the field were processed in excel spreadsheet. The results showed the occurrence of 610 individuals belonging to 82 species, 34 plant families, with a diversity index of Shannon & Weavers 2.77. The index of value of importance showed species Protium robustum,

Psico , 2012,
Abstract: Em um local estressante de trabalho, os amigos podem fornecer apoio e compreens o. Perder um amigo no trabalho significa deixar de ter uma fonte de ajuda (Sias, Heath, Perry, Silva e Fix, 2004). O rompimento de um relacionamento de amizade, em uma organiza o, pode ocorrer por vários motivos, como as personalidades dos amigos, as expectativas conflituosas, as trai es e as promo es. Nesta pesquisa, optou-se por explorar as promo es e compreender, a partir da percep o dos pares entrevistados, sua influência nas rela es de amizade. Foi utilizada a abordagem qualitativa, com entrevistas semi-estruturadas em profundidade, aplicadas a seis díades, em quatro empresas de grande porte, analisadas através de análise de conteúdo. O estudo apontou para o questionamento quanto à existência da rela o de amizade no local de trabalho e evidencia a falta de consenso na caracteriza o deste tipo de rela o. In a stressful workplace, friends can provide support and understanding. Losing a friend at work means no longer have a source of help (Sias, Heath, Perry, Smith and Fix, 2004). The breakup of a relationship of friendship, in an organization, can occur for several reasons, such as personalities of friends, conflicting expectations, betrayals and promotions. In this research, we chose to explore the promotion and understanding, from the perspective of couples surveyed, their influence in the relations of friendship. It was used a qualitative approach with semi-structured in-depth, applied to six dyads in four large companies, analyzed using content analysis. The study pointed to questions about the existence of a relationship of friendship in the workplace and highlights the lack of consensus on the characterization of this type of relationship.

Revista da Escola de Enfermagem da USP , 1998, DOI: 10.1590/S0080-62341998000300009
Abstract: this investigation was carried out in order to: identify the occurrence of professional accidents with perforate cutting potentially contaminated material among nurses and nursing auxiliaries that work in a general teaching hospital in the interior of the state of s?o paulo. the other objectives were: to associate the occurrence of accident with the professional category and period of work; to identify the type of perforate cutting material most involved in accidents, to identily the attitudes taken by the person accidented. the data were collected on individual interview based on a structured formulary in which the following information was registered: the probable reason of accident, how long the professional has been working on such function, the material involved in the accident, the actions taken after the accident. it was evidenced that the standard precautions or the universal precautions as they used used to be nominated are not being used as they should be. such attitude brings risks to the nursing team. we think that this team needs specific orientations through continuing education concerning the theme.
