Adsorption of Zinc from Aqueous Solutions Using Modified Brazilian Gray Clay  [PDF]
Patrícia N. M. Vasconcelos, Wellington S. Lima, Marta L. P. Silva, André L. F. Brito, Hervé M. Laborde, Meiry G. F. Rodrigues
American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.49065
Abstract:

In this study, the removal of zinc (Zn2+) from aqueous solutions was investigated using a Na-enriched Brazilian gray clay. The mineral clays were characterized through EDX, XRD analysis and CEC. A finite bath system was used to evaluate the main effects of mechanical agitation (from 100 to 200 rpm), pH values in the range from 6.0 to 8.0 and Zn2+ initial concentrations (from 10 to 50 mg/L) on the removal process capacity. Langmuir and Freundlich isotherm models were applied in order to determine the efficiency of clay used as an adsorbent. According to the obtained results, Langmuir model adjusts very well to the experimental data. Based on the kinetic studies for the Na-enriched gray clay, it was verified that the mechanism corresponds to a predominant pseudo-second order adsorption, presenting a kinetic constant value equal to k = 1.13 (g.min/mg).

The Technology Roadmapping Method and its Usage in Chemistry
Vasconcelos Loureiro,Aline Marta; Borschiver,Suzana; de Andrade Coutinho,Paulo Luiz;
Journal of technology management & innovation , 2010, DOI: 10.4067/S0718-27242010000300013
Abstract: technology roadmapping is a widely used technique in the industry for the development of long term planning strategies, making it possible to align market, product and technology over time. this article offers a brief review of this tool, covering the definitions of the terms technology roadmap and technology roadmapping, the types and formats of roadmaps, the structure of roadmaps, the processes of operation/adaptation of roadmapping, challenges and the key successful factors in implementing the roadmapping and its usage. finally, an overview of public domain roadmaps is given, with special highlight to the ones related to chemistry.
Occurrence of early adverse events after vaccination against influenza at a brazilian reference center
Lopes, Marta Heloísa;Mascheretti, Melissa;Franco, Marilia Miranda;Vasconcelos, Ricardo;Gutierrez, Eliana Battaggia;
Clinics , 2008, DOI: 10.1590/S1807-59322008000100005
Abstract: introduction: since 1999, the ministry of health in brazil has conducted campaigns of vaccination against influenza targeted towards the elderly, chronically-diseased people and health care workers. the vaccine against influenza is associated with adverse events of minor importance. objective: to investigate the early adverse events related to the vaccine against influenza. casuistics and methods: one hundred and ninety seven elderly individuals and health care workers vaccinated against influenza were included. an inquiry regarding adverse events related to the vaccine was applied seven days after the vaccination. results: local adverse events were reported by 32.5% and systemic effects by 26.4% of the vaccinated subjects. pain in the region of the injection, headache, myalgia, malaise, and coryza were more frequent in the workers than in the elderly (p<0.05). there was no statistically significant difference in the occurrence of fever. conclusions: the belief of part of the population that credits frequent and uncomfortable adverse events to the vaccine was not confirmed. the subjective adverse events were more frequent in the health care workers, which can influence, in a negative way, the disclosure of the benefits of this vaccine due to their role as opinion makers.
Integrative review of the nursing interventions used for the early detection of cervical uterine cancer
Vasconcelos, Camila Teixeira Moreira;Damasceno, Marta Maria Coelho;Lima, Francisca Elisangela Teixeira;Pinheiro, Ana Karina Bezerra;
Revista Latino-Americana de Enfermagem , 2011, DOI: 10.1590/S0104-11692011000200028
Abstract: in a national program to combat cervical uterine cancer (cuc) four basic elements should exist: primary prevention, early detection, diagnosis/treatment and palliative care. of these, early detection is the most effective modality. one of the purposes of evidence-based practice (ebp) is to encourage the use of research results with the assistance provided, reinforcing the importance of research for clinical practice. this study aimed to evaluate the evidence available in the literature regarding effective nursing interventions for the early detection of cuc. the selection of articles was performed in the databases: scopus, pubmed, cinahl, lilacs and cochrane. the sample of this review consisted of seven articles, with evidence levels 1, 2 or 3. the behavioral, cognitive and social interventions, showed positive effects in the early detection of cuc, especially the interactive cognitive interventions. it is suggested, when appropriate, to use a combination of interventions in order to obtain a more effective result.
O efeito do tempo de equilíbrio sobre a qualidade do sêmen caprino criopreservado
Rodrigo Freitas Bittencourt,Antonio de Lisboa Ribeiro Filho,Sidney Gon?alves Gonzalez Alves,Marta Freitas Vasconcelos
Revista Brasileira de Saúde e Produ??o Animal , 2006,
Abstract: Sete amostras de sêmen de um caprino adulto, colhidas com a utiliza o de vagina artificial, foram submetidas a criopreserva o, com o objetivo de verificar a influência do tempo de equilíbrio sobre a congelabilidade do sêmen caprino. O tempo de equilíbrio foi considerado o tempo total em que os espermatozóides forma mantidos em contato com o glicerol e com os demais componentes do diluidor, previamente a congela o. Logo depois da colheita e avalia o, o sêmen foi diluído e envasado em palhetas de 0,25mL, com dose inseminante de 100 x 106 espermatozóides. Essas foram encaminhadas para o resfriamento, com uma curva média de resfriamento de -1,07oC/min, até atingirem a temperatura de 5oC (30min de período de resfriamento). Depois desse período as amostras foram mantidas a temperatura de 5oC até completarem 1, 2, 3 e 4h de tempo de equilíbrio total, repectivamente G1, G2, G3 e G4. Posteriormente, congeladas em vapor de nitrogênio líquido. A descongela o foi realizada em banho-maria a 37oC por 30s. Através dos parametros espermáticos estudados, o tempo de equilíbrio de 2h (G2) foi o protocolo que obteve os melhores índices de viabilidade espermática após o processo de congela o-descongela o, quando comparado com os demais grupos avaliados.

Claudiniete Maria da Concei??o Bezerra Vasconcelos,Marta Lenise do Prado
Revista Eletr?nica de Enfermagem , 2004,
Abstract: This is a cutting of my máster, thisI had as objective to know the nurses-educators self-criticalexpressions concerning the working process on professional teaching for technical nursing. was based on theconstructive, social-interactive conception by Vygotsky, which assembled expressions from a nursing teachinggroup who works in a Brazilian South region state. There were carried out thematic and systematic meetings withthe subjects of this study where their reports about their respective pedagogical experiences were explored. It wasused the method proposed by Trentini and Paim as an analysis procedure. The results point out that these nurseseducatorsexpress their pleasure of working with technical nursing teaching. They also show that the different kindof problems they face during the working process can lead them to all sort of devaluation. Apart from this, theresults point out some aspects that are indicatives of internal organization of a social institution as interactiveamong the subjects of this education level. It also shows that this kind of organization seems to keep changing thepedagogical competence of this group.

Abstract: O conhecimento tem sido reconhecido como sendo um dos principais recursos estratégicos das empresas no mundo atual e, em conseqüência, a aprendizagem tem sido considerada como sendo o processo mais importante. As empresas mais inovadoras e competitivas s o aquelas que desenvolvem a habilidade de gerenciar o conhecimento, incorporando-o aos seus produtos e servi os. Dentro deste cenário, a gest o do conhecimento e a implementa o de uma cultura da aprendizagem devem estar inseridas no conjunto de estratégias das empresas. Mas qual é a realidade das empresas brasileiras em rela o a estas quest es? Este artigo prop e uma sistemática para avaliar a gest o do conhecimento e a aprendizagem nas empresas e analisa o comportamento de empresas mineiras frente a estas práticas, focalizando as pequenas e médias empresas (PME).
