Projeto e constru??o de um bioreator para síntese organica assimétrica catalisada por saccharomyces cerevisiae (fermento biológico de padaria)
Pereira, Ricardo de Souza;
Química Nova , 1997, DOI: 10.1590/S0100-40421997000500017
Abstract: a model for the construction of a simple and cheap apparatus to be used as bioreactor for reactions catalyzed by baker's yeast (saccharomyces cerevisiae) is described. the bioconversion and separation of cells from products and residual substrates are obtained at the same time. the reactions carried out in this type of reactor are faster than those catalyzed by immobilized cells. yeast cells can be cultivated in this bioreactor operating with cell recycling at appropriated conditions using glucose and other nutrients.
A crian?a no Estado Novo: uma leitura na longa dura??o
Pereira, André Ricardo;
Revista Brasileira de História , 1999, DOI: 10.1590/S0102-01881999000200008
Abstract: this article analizes the discourse that justified the launching of a chilcare programe by the estado novo regime, in 1940, with the foundatiton of the departamento nacional da crian?a. i argue that this discourse belonged to a conservative view of the dualist metaphor concerning adults and children behavior as a struggle between evel and goodness, started in the xviii century. here, the discourse is depicted into its fundamental elements and compared to two differentes interpretations on the same issue: the feminist moviment project of social care and a critical study by the sociologist guerreiro ramos. i argue that simbolic elements of a collective mentality can be read in different ways.
Métodos n?o-invasivos para análises hormonais aplicadas aos estudos de ecologia e etologia
Pereira, Ricardo José Garcia;
Revista Brasileira de Zootecnia , 2007, DOI: 10.1590/S1516-35982007001000008
Abstract: the endocrine monitoring through urinary and fecal steroid analysis has been proven a feasible alternative in the investigation of reproductive and stress physiology in a great variety of birds and mammals (domestic and wild species). this approach has contributed to enhance integration between endocrinology and behavioral/ ecological studies originating detailed information towards different areas, such as animal welfare, social behavior, reproduction, conservation biology, biomedicine, among others. in brazil, however, its application has been limited mainly to the determination of reproductive and stress parameters in wild species, with no published articles employing measurement of urinary or fecal glucocorticoids or sexual steroids in domestic animals. thus, the aim of this lecture is first show examples of brazilian researches involving non-invasive endocrine monitoring, and secondly illustrate possible applications of this technology in studies involving domestic animals.
Pre-travel health advice for human immunodeficiency virus-infected travelers, from Rio de Janeiro
Igreja, Ricardo Pereira;
Revista da Sociedade Brasileira de Medicina Tropical , 2009, DOI: 10.1590/S0037-86822009000300005
Abstract: counseling for human immunodeficiency virus infected travelers is becoming increasingly specialized. previous studies have reported the experience of hiv-infected travelers from temperate-climate countries but little is known about hiv-infected travelers from tropical countries. a retrospective study was conducted on hiv-infected travelers presenting at a travel health clinic in rio de janeiro. eleven journeys by ten people were recorded. brazil (amazon region and northeast) was the destination for six journeys. other destinations were peru, angola, europe and asia. nine attendees were undergoing antiretroviral therapy. few hiv-infected people from rio de janeiro consulted a travel medicine specialist before traveling. since they travel to destinations in brazil and abroad where there are endemic diseases not encountered in rio de janeiro, careful pre-travel planning needs to be undertaken. strategies for increasing the frequency of pre-travel consultations need to be developed, such as closer collaboration between hiv clinics and travel health clinics.
Estrutura de capitais comparada: Brasil e mercados emergentes
Leal, Ricardo Pereira Camara;
Revista de Administra??o de Empresas , 2008, DOI: 10.1590/S0034-75902008000400007
Abstract: this article offers a comparative analysis of capital structure patterns of firms in emerging markets by means of an analytical survey of the literature that employs cross section samples of firms from many countries and analyses them jointly. this article does not focus on the analysis of capital structure on a country by country basis. only listed firms are discussed. the influence of country level explanatory factors is compared to the explanatory power of industry level and firm level factors. the main deliverables are several stylized facts identified in the survey of the literature. country level factors are not irrelevant even though firm level factors seem to dominate them. yet, industry level factors are not very important. debt ratios of emerging market firms have risen over time and the degree of creditor and investor protection have a favorable impact over them. the m&m hypotheses are only partially supported by the emerging market evidence.
A crian a no Estado Novo: uma leitura na longa dura o
Pereira André Ricardo
Revista Brasileira de História , 1999,
Abstract: O artigo trata do discurso que justificou a constitui o do programa de prote o materno-infantil lan ado durante o Estado Novo, em 1940, a partir da cria o do Departamento Nacional da Crian a. Sustenta-se aqui a idéia de que ele correspondeu a uma leitura conservadora da metáfora dualista, formalizada no século XVIII, que resultou em demoniza o do adulto e endeusamento da crian a. Para tanto, o discurso é remontado em seus elementos fundamentais e comparado com duas interpreta es diferentes sobre o mesmo tema, com as quais se defrontou: a proposta de política social do movimento feminista (dos anos 30) e uma análise crítica do sociólogo Guerreiro Ramos. Ao fim, procura-se demonstrar que elementos inscritos na mentalidade coletiva podem ser lidos de maneiras diversas.

Marcelo Ricardo Pereira
Revista Espa?o Acadêmico , 2011,
Abstract: Como admoestava Freud: uma escola deve conseguir mais do que n o impelir seus alunos ao suicídio; ela deve lhes dar o desejo de viver. Mas como fazê-lo? Como n o nos sentir impotente frente ao outro que demanda aprender? Como refrear o gozo do capital e a tirania dos manuais pedagógicos? Como consentir as incertezas e ambivalências próprias do gesto de educar? Como subverter a vontade de ignorancia do outro sem abandoná-lo fazendo valer assim seu desejo de viver? Eis o que abordaremos.
Editorial Note

Revista Brasileira de Finan?as , 2009,
Abstract: The Editorial Policy Committee of the Brazilian Finance Review approved to increase the number of issues per year from 3 to 4 during 2009. Thus, it is my pleasure to announce that the publication of issue 3 of volume 7 (this issue) has been anticipated from December to September of the current year and that we will publish a new issue in December. The growth in the number of submissions and the quality of the articles published enable this important step towards the consolidation of RBFin. In the beginning, in 2003, we published two issues per year, in 2008 we published 3 issues and we have already reached 4 issues per year in 2009, fulfilling one of the initial objectives of the Review which was to be a quarterly publication as soon as it consolidated. I thank the effort of all of those that helped RBFin to be the
