The colection História Nova do Brasil, produced and published in the early 1960s by a group of intellectuals of the Instituto Superior de Estudos Brasileiros (ISEB), has become a field of discussion and debate among military and the left after 1964. Accused of promoting communist subversion, the collection had a new methodology to analyze the history of Brazil, with marxist approach. For this and other reasons, copies were seized by military agencies and the authors were indicted in military investigations, accused of violating the National Security Law.

No ano de 2005 o Herbário Rioclarense (HRCB) recebeu em doação pelo Museu Vicente Pallotti a coleção de exsicatas mantida pelo fundador do referido museu Padre José Pivetta. A maioria dos espécimes consistia de amostras de pteridófitas e angiospermas obtidas durante as décadas de 1950 e 1960 no Estado do Rio Grande do Sul, contudo, há exemplares provindos das regiões Norte e Centro-Oeste brasileiras e algum exemplares argentinos. A coleção apresentava-se em precário estado de conservação sendo necessária imediata remontagem dos materiais não deteriorados pela ação do tempo e/ou microorganismos e preservação das etiquetas originais. Os dados contidos nas etiquetas confeccionadas principalmente pelo Pe. José Pivetta foram copilados para uma planilha de dados do tipo Microsoft®Excel® 2000 e as exsicatas foram integradas ao acervo do Herbário RioClarense da Universidade Estadual Paulista (UNESP) campus de Rio Claro. A informatização dos herbários, agilizando a busca de dados para as pesquisas em botânica e ciências afins e tornando as informações aí depositadas disponíveis para um público mais diversificado, é fundamental para o avanço da ciência, ao acelerar a troca de informações e facilitar o gerenciamento de coleções (Brito & Joly, 1999). O trabalho de taxonomistas e pesquisadores correlatos é amplamente beneficiado com a presença de herbários bem organizados cujo acervo encontra-se informatizado e disponível para acessos. Ao todo nesta coleção foram recuperadas 2306 exsicatas pertencentes a 144 famílias. Dentre as mais representativas pode-se citar as Asteraceae com 236 exemplares (10,23%), Fabaceae com 174 exemplares (7,54%) e Pteridaceae com 85 exemplares (3,69%). Apesar de grande parte da coleção possuir identificação parcial, 54 exsicatas (2,34%) não a possuem, fato este verificado...(Resumo completo, clicaracesso eletrônico abaixo)

To isolate, to concentrate and to purify bacteriophages from isolates of P. aeruginosa; To observe the capacity of bacteriophages to infect isolates of P. aeruginosa susceptible and multiresitant to antimicrobial; To caractherize bacteriphages by electronic microscopy techniques. 10 isolates of Pseudomonas aeruginosa from LEMC culture collection were submitted to the experiments of ideal temperature for the lyse region appearance in the MaConkey culture plate and 2 extraction methods for the concentration of the phages, clorophorm (Silankorva) and filtration plus centrifugation (Bergan). Three infected clinical isolates of multiresistant P. aeruginosa an one susceptible isolate ( PA01) were evaluated by 3 transmission electron microscopy techniques to caractherize phages morphologically (“on grid”, “on drop” and direct extraction from the lyse region of the culture plate). The ideal temperature to obtain lyses region was 37°C. The stock solutions, obtained through the methodologies of Sillankorva and Bergan, had satisfactory results in infecting the multiresistant isolate and the negative control. Among the 3 techniques of electronic microscopy tested the direct from the lyse plate was the best to obtain the micrography of the phages

The increase of the antimicrobial resistance and its propagation around the world are the biggest threats to the public health care and to the treatment of diseases caused by microorganisms. Nowadays the antimicrobial resistance has increased abruptly. The essential oils are volatile and aromatic compounds derived from parts of plants as flowers, leafs, fruits, seeds, roots, sprouts, among others. The activity of extracts and essential oils of several plant species have been recognized and studied by empirical methods since a long time, but its antimicrobial activities were confirmed recently. Medicinal plants are used in folk medicine as medicines, antibiotic, analgesic, sedative and anti-inflammatory. The use of medicinal plants like source of medicines is an alternative of therapeutics for diseases treatment. In Brazil, studies with this goal are very important, once medicinal plants have been used as a choice of treatment and prevention of infections and diseases in health areas. Considering the fact that some products from medicinal plants have antimicrobial properties it is expected that using screening programs, new potential medicaments could be developed. Otherwise, scientific researches focused on determining therapeutic potential of plants are limited, there are lack of scientific studies which confirms the potential antibiotics properties of a large number of plants. The aim of the present study is determinate the antimicrobial activity of 10 medicinal species belonging to CPMA - Collection of Medicinal and Aromatic Plants from CPQBA/UNICAMP. The minimal inhibitory (MIC) and minimal bactericidal or fungicidal concentration (MBC) will be determined against the bacteria Escherichia coli, Pseudomonas aeruginosa, Salmonella choleraesuis, Staphylococcus aureus and the yeast Candida albicans. Furthermore, will be conducted chemical identification and fractionation of essential oils and extract with better activity

Toys are undoubtedly an important tool for healthy child development. Designers, as toys creators need to get theoretical bases of multidisciplinary to be able to define the issues around them with clarity and certainty. To analyze what makes the toy be efficient and present on child's routine is crucial to define this problem. To this end we need to probe his universe and find ways to turn the products more attractive to him. This paper discusses issues about the toy's world and describes a project developed in its bases that must value the national culture.
