O lazer nas empresas de Rio Claro: uma análise das razões e atividades envolvidas

A busca pela qualidade de vida dos funcionários e o aumento da produtividade têm sido fatores geradores do interesse de empresas, na busca por proporcionarem, dentro das próprias organizações ou em centros agregados, formas de atividades inovadoras, disponibilizando espaços de vivências do lazer e de atividades anti-estresse aos funcionários, especialmente utilizando a recreação e as atividades lúdicas, aspectos que representam diferenciais importantes na contemporaneidade. Sendo assim, este estudo busca analisar como e com que finalidades as empresas de diferentes portes da região de Rio Claro oferecem as atividades recreativas e de lazer para os mesmos. O estudo, de natureza qualitativa, será composto pela união de pesquisa bibliográfica e exploratória, desenvolvida por intermédio de entrevista semi-estruturada como instrumento para coleta de dados, aplicada a uma amostra intencional, composta por organizadores e funcionários que participaram ou participam destas vivências oferecidas pelas empresas, as quais serão previamente selecionadas e identificadas conforme o porte, tipo de atividades oferecidas e anuência para participação no estudo, na cidade de Rio Claro, SP. Os resultados serão analisados por meio da utilização da técnica de Análise de Conteúdo Temático.

Avaliação da cobertura de formas de vida no estrato herbáceo e sua relação com a diversidade da regeneração natural de lenhosas em Mata Atlântica

A comunidade vegetal pode ser constituída por diversas formas de vida, envolvendo desde plantas vasculares a não vasculares, bem como uma ampla gama de grupos taxonômicos e funcionais. Sendo considerada parte integrante do ciclo de crescimento florestal associados às fases iniciais do estabelecimento e desenvolvimento deste ciclo. Espécies herbáceas e subarbustivas, uma guilda importante, mesmo dentro de formações florestais, possuem um grande poder de colonização e modificação da comunidade, com isso o estabelecimento de indivíduos de porte arbóreo pode ser restringido pelo aumento de biomassa dessas espécies, pois tais vegetais por encobrirem o solo podem inviabilizar o processo germinativo do banco de sementes, transitório ou permanente. Este estudo analisou a relação entre cobertura de Arecaceae, Samambaias, Poaceae e Bromeliaceae, e a densidade e diversidade da regeneração natural de lenhosas em um trecho de Floresta Ombrófila Densa situada no Parque Estadual Carlos Botelho. Formam inventariadas 120 parcelas contidas em 6 transectos. Cada transecto contou com 20 parcelas (1m X 1m), sendo que 10 delas estavam inseridas em locais onde ocorrem manchas de Calathea communis (Maranthaceae) e as outras 10 em locais desprovidos desta espécie. Os indivíduos regenerantes foram divididos em 3 classes de altura, a classe A compreendeu plântulas lenhosas de 10 a 15 cm, a classe B de 16 a 50 cm e a classe C envolveu jovens de 50 a 150 cm.. A quantificação da cobertura das diferentes guildas foi realizada em manchas com presença e ausência de Calathea communis, no interior das parcelas. Através de uma análise de variância, conclui-se que existe uma tendência da Calathea communis interferir na cobertura de todas as formas de vida estudadas. Para as Arecaceae, Samambaias, Poaceae e Bromelias, o teste de ANOVA two-way, mostrou uma variação significativa (p<0,05), em pelo... (Resumo completo, clicar acesso eletrônico abaixo)

Pós-processamento de formas de ondas oriundas de descargas atmosféricas no Centro de Estudos de Descargas Atmosféricas e Alta Tensão (CENDAT) – IEE/USP

Atmospheric Discharges are responsible for several lost in the electrical system therefore it´s done studies to find ways to reduce the problem caused by discharges. This branch of engineering is necessary the gathering, stock and analysis of large quantity of data to validate or refuse the many studies produced about it The CENDAT proposed a project to collect data on induced voltages in distribution lines and current waveform of the lightning, but a difficulty that arose was the accumulation of data due to lack of manpower available to catalog all the data collected. Thinking in this difficulty, the engineer Acacio Silva Neto CENDAT´s researcher with trainees began to develop a program to solve this problem. This work keeps the development of this program in order to solve the problem of accumulation of data

Benefícios à saúde dos compostos Eriodictiol, Hesperidina e suas formas derivadas

Os flavonoides são compostos naturais presentes em diversos tipos de plantas e vegetais, quimicamente classificados como polifenóis e geralmente encontrados em sua forma livre ou glicosilada. Os compostos eriodictiol e hesperidina são flavonoides derivados de frutas cítricas, sendo o primeiro predominantemente presente no limão e o segundo em laranja. Seus principais efeitos quando consumidos por humanos incluem melhorias do sistema cardiovascular, efeitos anti-inflamatórios, antimicrobianos, anticâncer, antifertilidade, antinociceptivo, antioxidante entre outros. Os mecanismos principais envolvidos correspondem desde interações com enzimas regulatórias, à capacidade quelante de alguns flavonoides em sequestrar radicais livres.O uso de alternativas terapêuticas com o eriodictiol e a hesperidina já vem sido utilizada há anos e os mecanismos propostos para a explicação de seus efeitos elucidados.

Avaliação de gastrocitoproteção, mecanismo de ação e comparação do efeito da vitamina E (α-Tocoferol) nas formas natural e sintética

The aim of this study was to verify if α-tocopherol, the main substance of Vitamin E and also the one with the major antioxidant propriety, could offer citoprotection to a stomach damaged by alcohol. There are many forms of α-tocopherol, two forms of them were evaluated; d-l-α-tocopherol, the synthetic form and d-α-tocopherol, the natural form of α-tocopherol. Three experiments were made, all of them having absolute ethanol as the lesion agent, but the period and the doses changed in each of them. In the first two experiments, each group of animals received a different form of α-tocopherol and in the third experiment, they’ve received α-tocopherol p.o. for the period of seven days before the lesion agent was administrated. Moreover, immunohistochemistry assays were made from the stomachs samples of the third experiment to verify possible mechanisms involving nitric oxide and 2-cyclooxygenase. Satisfactory results of citoprotection have been obtained when the two forms were administered in the period of one week at doses of 100 mg/kg for synthetic form and 150 mg/kg for natural type. Nevertheless, the two forms didn’t differ statistically in their effectiveness against ethanol. The immunohistochemistry assays showed an increase of the levels of NO and COX2 in relation with the negative control, although there was no correlation between this increase and the gastroprotective effect. In conclusion, α-tocopherol has gastroprotection effect in some doses, but apparently there is no such a thing like the better the dose, the better the effect; that citoprotection don’t have a relationship with NO neither with COX2; the natural and the synthetic form don’t differ in their gastroprotection effect. More studies must be done looking forward an effective dose and also to understand the mechanisms underlay the citoprotection of α-tocopherol in the stomach

O Grupo Sobrevento de teatro de formas animadas

Since prehistoric man seeks to dominate play scenes and images of their daily lives, to understand them or dominate. In the theater, the man tried to represent hunting scenes and deities. Since the first creation material representative of the gods, these objects acquire magical powers. After a long time, came the Puppet Theater, which through the use of various materials, the man concocted dolls in his image and likeness, as well as representations of animals. Subsequently, the Theater of Animated FormsVisual involved various props, like the mask, the shadow and the object. Thus, these elements can appear all together or not in the same show and are, therefore, the Theater of Animated Forms. How important human need to understand the world and events around them, the arts were needed to explain the divine and unreachable. Clumping the four languages of art: music, plastic arts, dance and theater, the Theater of Animated Forms of so characteristic of the man in search of the divine and sublime sentiments or not. In Brazil, faced with a multitude of excellent groups Theater of Animated Forms, the Sobrevento Group stands to monitor on an extensive repertoire theoretical foundation for the themes of the pieces created, and the high level of aesthetic sensitivity and artistic creation through is the dummies used in your repertoire. The objective of this study is to describe and analyze the Sobrevento Group considering the process of artistic creation, which led to the understanding of what is Theater of Visual Theater. To this end, guided interpretive anthropological approach, we conducted an ethnograph with the group

Energia, suas formas e transformações: uma abordagem contextualizada por meio de material não-formal

Energy is a physical quantity very present in physics. Although extremely useful, its concept is very abstract for most students in high school and college. Identify the presence and form of energy in a given phenomenon is not simple, as there is immediate understanding on the transfer and transformation. This work emphasizes the study of mechanical energy in its different forms as well as the thermal energy, considering the possible transformations between them. To this end, use is mad of toys, exploring its potential as an alternative material to be use in supplement classroom teaching in primary and secondary levels. The proposed use of ludic pedagogy takes into account the author’s experience as an intern project Toy Scientific Department of Physics and its role as mediator in the workshops offered by the project to school at these levels

Produção de vetores recombinantes para expressão de diferentes formas da proteína K1 do herpesvírus associado ao Sarcoma de Kaposi (KSHV)

Kaposi´s sarcoma associated herpesvirus (KSHV) or human herpesvirus 8 (HHV-8) is a gammaherpesvirus essential for the development of all forms of Kaposi´s sarcoma (KS). The KSHV’s life cycle is basically divided into latent and lytic phases, which have distinct viral gene expression profiles. Some important oncogenic products of KSHV are expressed during the lytic phase, including the viral K1 protein. As an effect of interfer-ence with intracellular signaling, K1 expression increases proliferation and survival of KSHV-infected cells. Due to its high level of genetic variability compared to other re-gions of the viral genome, the K1-encoding ORF (ORF-K1) is commonly evaluated for KSHV genotyping. It remains unclear whether different viral genotypes have particular biological effects that might modify the KSHV oncogenicity. The present study aimed to contribute to the establishment of an experimental in vitro model for evaluation of the K1 protein from common KSHV genotypes. Recombinant expression vectors with the ORF-K1 from KSHV genotypes A, B and C were prepared by genetic cloning. The recombi-nant vectors pKSHVOK1 obtained by cloning were sequenced for structural validation. After that, HEK293 cell line was transfected with the recombinant vectors, and proteins were extracted for expression analysis by Western blot technique, for K1 functional vali-dation. Results showed that ORF-K1 vectors containing KSHV ORF-K1 from the A, B and C genotypes were produced and structurally validated by DNA sequencing. The K1 expression at the protein level was also confirmed by immunoblots using an antibody for FLAG detection, an epitope from the vector that binds to K1. Based on presented re-sults, it´s possible to conclude that the recombinant vectors will be able to be used in future studies of K1 protein biological properties from distinct KSHV genotypes

Soluções numéricas de Equações Diferenciais Fracionária e Ordinária para o cálculo da distribuição da concentração em um sistema de compartimento

The purpose of this work was the study of numerical methods for differential equations of fractional order and ordinary. These methods were applied to the problem of calculating the distribution of the concentration of a given substance over time in a given physical system. The two compartment model was used for representation of this system. Comparison between numerical solutions obtained were performed and, in particular, also compared with the analytical solution of this problem. Finally, estimates for the error between the solutions were calculated

Das formas de ensinar e conhecer o mundo: lições de coisas e método de ensino intuitivo na imprensa periódica educacional do século XIX

This article analyses A Eschola Publica, an educational journal that circulated in São Paulo state between 1893-1894 and 1896-1897, whose editors, allied with the diffusion of republican ideas, helped the consolidation of objective method as a pedagogical efficient modern tool. It was possible gathering some sources that shows the acceptance of that method and the difficulties for its dissemination in the classroom, mainly those refers to teacher’s formation. Taking as referential bibliographical resources about schooling culture it was possible verifying that circulating in complementary parallel way to textbooks, the articles by A Eschola Publica endorse the innovative purposes and show barriers imposing on educational context. This journal produced a place for discussions and debates that contributed for controlling and producing symbolic resources

Paixão, mito e formas de vida em textos publicitários

The passion, understood by Aristotle, as a contingency which causes a change in the essence of the subject, was object of research of the Greek philosopher as rhetorical strategy used by the speaker to touch its listeners. The greimasian semiotics, enlarging the concept of Aristotle’s passion, understands it as the soul states of a subject that can be gathered form the analysis of a text. Reflections towards the passion discursivization and its persuasion effects in advertisements lead us to establish the relationships between passion, myth and ways of life.
