The brazilian-plum (Spondias tuberosa, His) is a tropical fruit tree that has been consolidated in the market for agribusiness processing, due to its characteristic flavor of fruit. Accordingly, studies to optimize the propagation of plants are necessary for production of seedlings with agronomic and quality assurance measures. This study aimed at determining the efficient techniques for uniform seed germination, as brazilian-plum seed present mechanical dormancy, and establish optimal culture media for multiplication of shoots from the in vitro micropropagation. Firstly, in a greenhouse at the Universidade Federal do Rio Grande do Norte, was evaluated the influence of different methods of breaking dormancy in the emergence of seedlings of brazilian-plum and speed of germination (IVG) of seeds. After 60 days of cultivation, it was found that splay in the distal portion of the seed was the best treatment, with rates of 85.33% in germinability and 3.415 of IVG, compared with the treatment of seed-soaking in water for 12h + humus and the control group. Subsequently, new sources of seedling explants were obtained in studies of tissue culture. Laboratory of Plant Biotechnology that the university, was used stem apex, nodal segments and internodes in search of decontamination with various concentrations of calcium hypochlorite [Ca(OCl)2] and micropropagation, inoculating them in half WPM (1980) with various concentrations of 6-benzylaminopurine (BAP). We used 10 sample units with three replications for different concentrations of [Ca(OCl)2], BAP and explants type. After thirty days, which was observed for the control of contamination, during the establishment in vitro, concentrations of [Ca(OCl)2] between 0.5% and 2.0% were effective in combating exogenous contamination of the apex. In nodal segments and internodes, concentrations of [Ca(OCl)2] between 1.0% and 2.0% and 1.5% and 2.0% were respectively, sufficient to reduce the percentage of losses in these infestations explants. For micropropagation, the culture medium supplemented with 0.1 mg.L-1 BAP promotes better development of multiple shoots per explants from nodal segment. However, success does not get to shoot training in internodal segment

Os estudos que aqui se apresentam correspondem à avaliação da Iniciativa Iniciação à Programação nas Escolas do 1.º ciclo em Portugal (adiante designada de IP1 ou simplesmente Iniciativa) desenvolvida durante o ano letivo de 2015-2016. Considerando a natureza de projeto-piloto da IP1, bem como as suas finalidades e características é adotada uma perspetiva de avaliação global, formativa e participada que assegurou a recolha de informação fundamental aos processos de tomada de decisão que visem o conhecimento sobre a implementação da Iniciativa e a sua eventual generalização à população das escolas do 1.º ciclo em Portugal. Os estudos de avaliação realizados têm como finalidade contribuir para o conhecimento e compreensão aprofundada das condições humanas e materiais em que a iniciativa IP1 foi implementada no conjunto das escolas e dos agrupamentos incluindo aqueles aspetos que possam vir a ser melhorados de modo a aumentar a eficácia de propostas futuras a desenvolver, identificando os pontos fortes e fracos bem como antecipando a avaliação de impacto que terá no momento da sua generalização a toda a população das escolas do 1.º ciclo em Portugal Tratando-se de um projeto-piloto espera-se que os resultados dos estudos de avaliação a realizar possam constituir um contributo para o conhecimento detalhado das estratégias de implementação levadas a cabo pelas Escolas e identificar prioridades, estabelecer procedimentos e requisitos que apoiem os processos de tomada de decisão, adquirindo pela via da investigação e da avaliação, o conhecimento antecipado das condições para efetuar a generalização prevista. A avaliação da IP1 foi desenhada e implementada a partir de duas linhas metodológicas de investigação, distintas, mas complementares e que deram lugar a 4 (quatro) estudos de avaliação. A primeira linha, de natureza quantitativa, inclui os estudos I e II e destina-se à avaliação global da IP1 através da recolha de elementos e indicadores de impacto quer ao nível da Escola quer ao nível dos professores e dos alunos. Os estudos I e II tiveram como opção metodológica o inquérito por questionário. A segunda linha de estudo, com carácter mais qualitativo inclui os estudos III e IV e destina-se a analisar e a compreender de forma mais aprofundada quer as ações realizadas pelas entidades parceiras ao longo da Iniciativa (nomeadamente as estratégias de coordenação, formação, acompanhamento e monitorização da Iniciativa) quer os eventuais impactos da Iniciativa observáveis nas Escolas. O estudo III teve como opções metodológicas a entrevista focus-group aos parceiros e outras entidades institucionais associadas à Iniciativa, a análise de conteúdo de material empírico recolhido através de questões abertas e pela preferência de cenários de alargamento da IP1. O estudo IV teve como opções o estudo de caso que recorreu a visitas “in situ” a escolas envolvidas na IP1. Em cada estudo de caso recorremos à observação de aulas, às entrevistas a professores e alunos e à análise documental, como técnicas de recolha de dados, de acordo com um protocolo de investigação comum a todos estudos. São apresentadas e discutidas as principais conclusões dos estudos de investigação e avaliação realizados, respeitando a estrutura organizativa adotada desde o seu início.

Neste artigo temos por objetivo geral analisar a distribuição espacial das instituições de ensino superior e das indústrias de alta tecnologia no território brasileiro. Para isto, nos utilizamos do referencial teórico, ao buscar referências bibliográficas que discutissem sobre o desenvolvimento dos pólos tecnológicos e das instituições de ensino superior. Como categorias de análise geográfica, utilizamos: espaço urbano, território e região. No referencial empírico, devido à dimensão do universo de pesquisa e da escala geográfica adotada, utilizamos fontes de dados secundárias, coletadas em institutos pesquisa estatais (INEP, IBGE, RAIS, ANTT e INFRAERO). A partir das técnicas de georreferenciamento dos dados coletados para os 5.564 municípios brasileiros elaboramos mapas temáticos, que nos permitiu compreender a distribuição das instituições estudadas, bem como as relações entre elas. As indústrias de alta tecnologia no Brasil se associam espacialmente e organizacionalmente com as instituições de ensino superior para capacitação de mão-de-obra, e secundariamente, para desenvolver novas tecnologias, visto que no Brasil estas indústrias são caracterizadas mais pela difusão de tecnologias de ponta, do que de fato pelo desenvolvimento de novas tecnologias em si.

Educação vai além de promover a instrução dos alunos, ultrapassa fronteiras conteudistas e promove mudanças comportamentais a partir das práticas vivenciadas no dia a dia. É dentro dessa concepção que se estrutura o Projeto Virtudes, desenvolvido pelo Bom Jesus, numa perspectiva de proporcionar ações que valorizem a formação moral dos estudantes inseridos no ambiente da escola. Para o desenvolvimento dessas atividades, os educadores são orientados a conhecer e reconhecer a virtude de cada turma como norteadora de suas práticas pedagógicas em sala de aula. Na Geografia, considerando as virtudes Sabedoria, Solidariedade, Diálogo e Disciplina, respectivamente do 6ª, 7ª, 8ª e 9ª ano, procurou-se criar atividades que pudessem contribuir para o desenvolvimento cognitivo e social sem privá-los dos conteúdos necessários para sua formação enquanto estudante daquela turma. A partir das técnicas utilizadas foi possível presenciar um crescimento exponencial considerando as necessidades de cada ação promovida, uma vez que procurou-se explorar diversas características individuais e coletivas dentro do espaço escolar. Assim, percebe-se que não são novas formas de educar necessárias, mas sim o resgate dos valores éticos e morais que devem ser encarados como base para a formação de uma sociedade mais consciente e cidadã, comprometida com a valorização da vida.

We evaluated children in the first grade of a elementary school using neurological examination. With no previous knowledgement of their educational performance, were invited all children attending five classes of the first grade of an elementary public school chosen randomly, in Itatiba / Sao Paulo / Brazil, whose parents assigned a Commitment Term for participation in this research. Children who missed three evaluations in different days or whose parents did not assigned the Commitment Term were excluded. The Traditional Neurological Examination (ENT) (Lefevre, 1972) was applied. It was considered for normal the measurement of the skull circumference, proposed by Diament & Rodrigues (1976), and the application of all ENT items. The data were stored in a database of the Epi6 Program (Epidemiologic Information), and analyzed by percentage calculation and by the c2 test. The significance level was 0.05. Children evaluated were 124. The ENT results were normal in 87 (70.16%) and altered in 37 (29.83%). Among the alterations, there were observed: light tremor, light muscular hypotonia, speech acquisition delay, macrocephaly, microcephaly, hyperactivity, cranial nerve syndrome, central facial paralysis. One child presented corticospinal tract impairment syndrome of the distal lower extremities.

This text offers some contributions to the debate on the changes proposed to the National Curricular Directives to reform secondary education in Brazil. In the first part, the political and economic scene is evaluated as the context which generated the last stage of reforms in the educational field in the 90s. It questions the option for a model of structural reform (in the Brazilian case more restricted to the Program for Reform of Professional Education - PROEP) and of the curriculum, whose themes find their justification in the contemporary economic, social cultural and political context. It discusses the use of a model that bases itself on experiences developed in other countries and takes the international orientation of the multilateral organizations as its theoretical methodological reference, leaving out the peculiarities and injunctions of the Brazilian political administrative system. Such a policy measure can increase the tension and distance normally existing between government programs and the possibility of their real implementation in the school network. In the second part, it discusses the Resolution of the National Education Council, the Congress on Basic Education, no.3, of 16.698 that instituted the National Curricular Directives for secondary education, as well as the Legal Bases - Part I - of the National Curricular Parameters for secondary education. The analysis of official discourse takes Bardin's (1977, p. 209) proposals as its methodological reference for the models of structural analysis, seeking to make the implicit values and the connotations of the legal texts explicit

This article takes the concepts of biopower and governmentality as the starting point for an analysis of certain recent Brazilian government documents about the introduction of Philosophy as a subject in secondary school. In the 1980s, this argument centered on Philosophy's so-called criticism and its potential for preparing citizens for a democratic society, was used by the movements aimed to restore democracy in Brazil. This argument appears to have been assimilated by the Brazilian government, because it is stated in the Guidelines and Bases of Education Law, secondary school students should demonstrate knowledge of philosophy necessary for the exercise of citizenship. The argument also appears in documents such as the PCN and PCN+ (National Curricular Parameters) and OCEM (Curriculum Guidelines for Secondary School) in their chapters on Philosophy. These documents are examined here in the light of governmentality, making explicit how Philosophy is equipped to train young people according to what is understood as a modern democratic society.

MIPs are synthetic polymers that are used as biomimetic materials simulating the mechanism verified in natural entities such as antibodies and enzymes. Although MIPs have been successfully used as an outstanding tool for enhancing the selectivity or different analytical approaches, such as separation science and electrochemical and optical sensors, several parameters must be optimized during their synthesis. Therefore, the state-of-the-art of MIP production as well as the different polymerization methods are discussed. The potential selectivity of MIPs in the extraction and separation techniques focusing mainly on environmental, clinical and pharmaceutical samples as applications for analytical purposes is presented.

A new practical experiment involving silver and gold nanoparticle syntheses was introduced in an inorganic chemistry laboratory course for undergraduate students at the Institute of Chemistry, UNICAMP. The nanoparticles were synthesized by the reduction of silver nitrate and tetrachloroauric acid with sodium borohydride and sodium citrate in an aqueous medium. Stabilities of the suspensions were tested using several different reactants including sodium chloride, polyvinylpyrrolidone, polyvinyl alcohol and cistamine. Changes in optical properties were observed by electronic spectra and also by transmission electronic microscopy, which also yielded data for estimating particle size.
