A história da educação em São Paulo: a instrução pública dada a ler nos Annuarios do Ensino do Estado de São Paulo 1907-1927

In this article we aimed the identification and the analysis of the “textual configuration aspects” from the speeches of the “high authorities” of public instruction in São Paulo contained in Annuarios do ensino do estado de São Paulo, centrally those published between 1907 and 1927, on the direction of public instruction and its teachers statewide. This formulation resulted from the need to search the peculiar aspects of these discourses, that is, from a conductor thread through which and by vitue of which these discourses have been produced. It was concluded at the end, the common orientation mentioned to speeches was to bring the idea together, a sense of unity to the sphere of public education in the state, which would characterize the called school apparatus in São Paulo.

Estudo das propriedades elétricas do cobre e alumínio; sobre a força magnética em um imã caindo dentro de um tubo

Magnetic fields can be produced by natural magnets, artificial magnets, and by circulating electric currents in wires and solenoids. An interesting experiment to observe the interaction between the magnetic field and free charges in a conductor, a magnet falling inside a tube made of conductive materials. The slowing down of the magnet by the appearance of a field in the opposite direction to the original one (Lenz's Law) is function the number of free electrons in the conductor and the electrical properties of this. Based on this, the objective of this study is to analyze the relationship between the electrical properties of conductors, copper and aluminum, with magnetic force on a neodymium magnet-iron-boron magnet falling inside a copper tube and aluminum, positioned vertically. In performing this experiment, we observed that it is a demonstration of Lenz-Faraday’s Law

Estudo das características térmicas e mecânicas de formulações de adesivos PSA HOT MELT contendo variações de borrachas SBC e resinas taquificantes

The properties of the hot melt adhesive pressure sensitive (HMPSA) using an elastomer as a base polymer a copolymer of styrene and butadiene (SBS) and variation of tackifiers resins such as hydrocarbon resins and hydrogenated hydrocarbon were investigated. The formulations were prepared by mixing process within shear. The adhesives prepared were evaluated in test Brookfield viscosity and softening point Ring and Ball to compare the formulations and the influence of variations in raw materials. Infrared analyzes were performed to detect the reactions between the inputs and investigate the chemical interactions of the same properties of the adhesive. In thermal analysis, the assay was performed thermogravimetry (TG) and diferencial exploratory calorimetry (DSC). Were investigated the parameters of the tensile test on each of the formulations. Finally, were analysed comparatively the basic formulations of adhesives with their respective raw materials

Desenvolvimento de nanopartículas de quitosana para adminstração nasal de zidovudina

Zidovudine (AZT) is the drug most commonly used in AIDS treatment, isolated or in combination with other antiretroviral agents, but it has certain limitations due to its therapeutic dose-dependent haematological toxicity. In addition, it has low oral bioavailability, since it undergoes pre-systemic metabolism. The nasal route has been used as an alternative route for drug administration, because it can promote its direct absorption to blood circulation, avoiding hepatic metabolism. However, this route presents as a factor limiting the mucociliary clearance mechanisms that remove quickly the formulation of the nasal cavity. To prolong the residence time of formulations, in this direction, has been proposed the development of mucoadhesive systems. Among the various existing systems, the use of chitosan (QS), as mucoadhesive polymer, has been widely exploited in the preparation of nanoparticles (NPs). The objective of this study was to develop and characterize QS’s NPs for intranasal administration of AZT. For both NPs have been developed by ionic crosslinking of QS with sodium tripolyphosphate (TPP). These NPs were characterized by studies of particle size distribution, zeta potential, morphology, mucoadhesion tests, assessing the ability of encapsulation of the drug and permeation profile of AZT. The evaluation of AZT in the NPs was determined by UV-Vis spectroscopy. Mucoadhesion measures were made using a texture analyzer, using a mucin disk and porcine mucous membrane , and permeation assay were conducted using porcine nasal mucous membrane adapted to the Franz cell. These results suggest that the systems in hand have great potential for nasal AZT administration

Biodegradação de filmes de polipropileno (PP), poli (hidroxibutirato-co-valerato) (PHBV) e blenda pré-irradiados com luz UV

This work intends to investigate the biodegradation of the polymers and blend films of polypropylene (PP) and poly(hidroxybutirate-valerate) (PHBV), after UV radiation to facilitate the PP degradation, which is a polymer with long chains difficult to degrade by biological agents present in the environment. This polymer is outstanding by its mechanical properties and versatility of industrial and commercial use and the PHBV by its quick biodegradability in the environment. Blends of these materials could to present a commitment between mechanical properties and biodegradability to execute its function and after the discard to have lesser lifetime in the garbage landfills. Another aspect of this work is the controlling effect of PP on PHBV, influencing its degradation time

Regime nazista: as teorias ideológicas e educacionais moldando a formação do indivíduo nazi

O período correspondente ao Terceiro Reich alemão (1933-1945), quando a Alemanha esteve sob o domínio do Regime Nazista, foi caracterizado pelo alto grau de violência, de dominação e de exterminação em massa, e, também, pelo envolvimento “voluntário” de crianças e jovens na luta por um ideal que não lhes pertencia, as quais foram, desde a mais tenra idade, doutrinadas para matar e morrer em nome desse ideal. Para atingir esse fim, teorias, supostamente comprovadas, foram concebidas e incorporadas a educação de modo a fazer dela o grande veículo condutor da dominação que se pretendia. Por este motivo, o seu estudo se torna de grande importância para se pensar na educação – do presente e do futuro -, no sentido de sua utilização para atingir fins que não possuem como premissa a formação do sujeito livre e emancipado, capaz de agir de forma reflexiva e autônoma no mundo em que vive. No presente trabalho, pretende-se apresentar o resultado de uma pesquisa desenvolvida a partir da revisão bibliográfica, sobre o contexto histórico, social, econômico e educativo da Alemanha nazista com a finalidade de proceder ao levantamento e a análise de dados e informações em torno dos principais fatores que contribuíram para a ascensão do Partido Nazista, na figura de seu líder, Adolf Hitler. O objetivo maior deste trabalho foi buscar argumentos que possibilitassem a compreensão em torno dos motivos que levaram os jovens e as crianças a seguirem Hitler e o seu ideal até as últimas consequências. Como metodologia utilizou-se a pesquisa bibliográfica, com base qualitativa e em caráter historiográfico e exploratório. O material bibliográfico analisado trouxe diversas possibilidades que, apesar de não conclusivas, permitiram a compreensão em torno da eficácia dos mecanismos educativos...

Estudo, construção e caracterização de diodos orgânicos tipo Schttky

During the twentieth century the inorganic electronics was largely developed being present in various industrial equipment or household use. However, at the end of that century were verified electronic properties in organic compounds, giving rise to the field of organic electronics. Since then, the physical properties of elementary devices such as diodes and organic transistors have been studied. In this work was studied the properties of diode devices fabricated with a semiconductor polymer, the poly-o-methoxyaniline (POMA). Devices containing electrodes of Au and Al were fabricated with semiconductor polymer of different doping levels. We found that the rectifying behavior for the heterojunctions metal/polimer are reached only for high doping level (with conductivity greater than 1,77. 10-9 S / cm), which gives the devices characteristic of a Schottky diode. The rectifying behavior was observed for electric fields of low magnitude, below the operating field (~ 600 V/cm), while for electric field greater than 600 V/cm the a linear behavior I vs.V was obtained. We determined that this Ohmic behavior arises from the charge transport over the volume of the semiconductor material after the lowering of the metal/semiconductor barrier. In devices with weakly doped semiconductor, the electrical resistance of the volume becomes high and the process of charge transportation is dominated by the volume, for any intensity of the applied electric field

História de vida e formação: educando o olhar e percebendo pesquisa enquanto experiência

Way in the theme of the story of my life and training and electingchildhood as a guide in the works of Benjamin. Narrating a series of reflections on childhood and experience, taking for reading and interpretation of aphorisms that make up my childhood and training as a fellow researcher, a full text simultaneously, is juxtaposed with other texts and authors, intertwining with Benjamin, memory and history in my narrative, in a singular moment, an event. In this course highlight the place ofexperience and their languages, between the know-how, andknowing how to express thinking about childhood and educationevent in the making, which announces the issue of impoverishment and destitution of the experience of life ineducational practice, indicating the possibility resume thembetween school knowledge and practices through different view of childhood and the event, as a teacher. I will continue outliningmy experience in research groups choosing the language and itsinterfaces specifically with art cinema / pictures in the construction of our subjectivity in postmodernity. The methodology is qualitative, will take place within what we call the ethical self. Transcendence is an act and not a process, and yetas an overshooting of history is always historically situated and,therefore, has a concrete context. Using my own journey as an educator / researcher in my path as an area of passage / travel / experience / track / time in the constitution of my subjectivity in my own life story
