Estudo sobre as unidades de medidas das grandezas físicas básicas: comprimento, massa e tempo

Measurement units are used almost automatically nowadays, but few people know the origin of the units of length (meter), mass (kilogram) and time (second). And do not care to know what were anciently units of which our ancestors used, the difficulties that existed to make a set of measures. The aim of this work is to make a historical approach, through various units of measure. They are old, unusual to others that have been forgotten since the standardization of meters, and is also discussed about the metric system Englih (Once and foot), AV system (eg pound grain) that are still used in some countries like United States and England, the Troy system consisting of units of measure for precious stones and metals (eg gold and diamond) are also cited some physical concepts as reference: inertial, non-inertial; mass: gravity, relativistic, inertial

Comparação entre dossel e sub-bosque de um trecho de floresta ombrófila densa Montana, Parque Estadual da Serra do Mar, Núcleo Picinguaba, SP, Brasil

Estudos a respeito da composição florística e estrutura fitossociológica da vegetação são de grande importância não só para estabelecer parâmetros e associá-los a comunidades semelhantes em diferentes locais ou sob influência de condições ambientais diversas. Também servem para subsidiar medidas conservacionistas diante do cenário atual de intensa fragmentação, aplicáveis sob perspectivas da ecologia da paisagem. Neste estudo, analisamos a composição e estrutura do subbosque de um trecho de Floresta Ombrófila Densa Montana, e comparamos com o dossel. Amostramos todos os indivíduos arbustivo e arbóreos que tiveram altura superior ou igual a um metro e meio e perímetro à altura do peito (PAP) menor que quinze centímetros (H ≥ 1,5 m e PAP < 15 cm) em uma área de 0,4 ha, totalizando 2321 indivíduos. Encontramos 252 espécies, distribuídas em 43 famílias para o subbosque e 583 indivíduos, 129 espécies e 36 famílias para o dossel. Os valores do índice de diversidade de Shannon (H’) foram, respectivamente, 4,13 e 3,94 nat.ind.-1 e os valores de equabilidade de Pielou (J) foram 0,75 e 0,81. As famílias de maior riqueza em comum nos dois estratos foram Myrtaceae, Rubiaceae e Fabaceae. A espécie com o maior valor de importânica do sub-bosque foi Psychotria nuda (VI = 9,33%), abrangendo 12,3% dos indivíduos. Já para o estrato superior, Coussarea accedens foi a que mais se destacou, com VI = 7,94%, (12,5% dos indivíduos amostrados). A comparação entre as parcelas revela similaridade na composição, principalmente entre parcelas pouco distantes geograficamente. Em relação à riqueza, podemos perceber uma diferença significativa entre as parcelas, de forma que a parcela Q2 apresenta maior número de espécies para o sub-bosque. Quanto aos estratos, notamos que estes apresentam riqueza semelhante quando comparados... (Resumo completo, clicar acesso eletrônico abaixo)

Otimização do braço inferior da suspensão dianteira do veículo Baja utilizando o método dos elementos finitos

Mass reduction coupled with the mechanical performance in service has been the goal of many projects related to the transport area, considering the advantages that mass reduction can bring. However, make a simple material substitution without design a new geometry to corroborate for the best component performance, often makes the replacement unviable. In this study, it was investigated the advantages of replacing the prototype BAJA SAE front suspension lower arm of Equipe Piratas do Vale de BAJA SAE - Universidade Paulista, Campus Guaratinguetá, actually produced with steel, for a new component made of carbon fiber composite. The new geometry has been developed to provide the best possible performance for this component and your easy manufacturing. The study was done using the 3D modeling tools and computer simulations via finite element method. The first stage of this work consisted on calculation of the estimated maximum contact force tire / soil in a prototype landing after jump at one meter high, drop test in the laboratory with the current vehicle, current front suspension lower arm 3D modeling, finite element simulation and analysis of critical regions. After all current component analysis, a new geometry for the part in study was designed and simulated in order to reduce the component mass and provide a technological innovation using composite materials. With this work it was possible to obtain a theoretical component mass reduction of 25,15% maintaining the mechanical strength necessary for the appropriated component performance when incited

Sílabas métricas em Terenciano Mauro, De Syllabis, 997-1299

This monograph addresses to the study of Latin metrical notions and concepts as showed in the volume VI of Heinrich Keil’s work, entitled Grammatici Latini (GL): Scriptores Artis Metricae. From that book, it was chosen Terentianus Maurus’s work for corpus, particularly the excerpt between verses 997 and 1299 of De Syllabis, a part of Terentianus’s De Litteris, De Syllabis, De Metris, which is a metric manual written in verses. Until now, there are only three translations of that text into modern languages: two in Italian (one of them was used for comparison with the translation prepared for this monograph) and a French one. That work still contains many reference notes whenever Terentianus Maurus uses ancient authors to demonstrate his explanations on Metrics. Thus this research intends to join in other analysis made on Latin metrical manuals that have already been translated or are still going to be, as well as to notice the importance and the specific value of meter in ancient poetry

Cálculo estrutural de barreiras: Desenvolvimento de um programa computacional de interface online

This study aimed to develop a computer program which systematizes the structural shielding design calculation in diagnostic radiology facilities. For this purpose methodology of the National Council of Radiation Protection and Measurements (NCRP 147[5]) was used. By comparative statistics studies, it was verified if reference parameters values suggested by the US publication correspond to the average national values. The World Wide Web was chosen because of its characteristics as a powerful mean of communication, especially in terms of the wide variety of useful resources and easy access. To compare the reference values of some parameters proposed by NCRP 147 to Brazilian average, studies about the normalized workload per patient, performance of X-ray tube and primary air kerma, unshielded, at one meter from the focal point of the X-ray tube were made. Through this research, relative differences were found. In workload values this differences reached up to 50% in mammography compared to those presented by the NCRP 147; in X-ray tube performance the percentage differences reached 69% in dental radiology, and air kerma results amounted 31% in fluoroscopy. This demonstrates the importance of validation of international protocols to local realities

Expresividad poética y traducción con breve lectura de Fedro I. 1

The term poetic expressiveness refers to the multiple joints of the plan of expression, derived from the expressive value of the linguistic sign (ROSSET: 1970, 135) and its particular role in the field of poetry. The features of meaning, such as projection, elevation and salience, make it possible to consider expressive all poetic statements which constitute particularly dense instances in the formal consolidation of a convergence between the two planes (expression/content), and therefore it stands out from the others due to the high density of structural parallelisms and isomorphisms, which are procedures responsible for the impression that a particular form of content can only be expressed by cutting that same specific form of expression out. These considerations have an immediate impact on the reading, interpretation and practice of translating poems, which is intended to be demonstrated here, through an example of translation of a Phaedrus' fable, written in iambic meter.

Análise de parâmetros de qualidade da água para consumo humano

The Current work to assess the capacity of water potability samples for that, we used seven different brands of mineral water, bought locally, and also collected seven samples of public drinking fountains located in different places on campus headquarters of the State University of Maringá. The parameters analyzed were presence of fecal and total coliform, turbidity, color and compounds with UV-absorption at 254 nm. On the analysis of coliforms, two brands of mineral water and four samples of drinkers showed presence of total coliform, but no analysis indicated the presence of fecal coliforms. In the turbidity parameter, all samples were within the limits allowed by law, for both cases. No apparent color attribute, two samples of mineral water and a sample of drinking were outside the range required by law. Finally, the determination of UV showed the values of light absorption of each sample at a wavelength of 254nm, however, does not yet exist in Brazil a regulation on this parameter. With such analysis, it was possible to compare the results with current legislation. After these findings, it appears that more stringent hygienic practices should be adopted throughout the processing of mineral water as drinking in public. It is also necessary for greater oversight over the other parameters for determining the quality of water.

Resistência de porta-enxertos de cucurbitáceas a nematóides e compatibilidade da enxertia em melão

Nematodes severely attack net melon plants under protected cultivation conditions. The objective of this research was to select rootstocks with resistance to Meloidogyne incognita and M. javanica. The experiment was carried out under greenhouse conditions from October 2010 to April 2011 in Jaboticabal, Sao Paulo state, Brazil. Thirty-three cucurbitaceous genotypes were investigated as rootstocks; melons: CNPH 01-930 (Cucumis melo var. flexuosus), CNPH 01-962, 01-963 CNPH (Cucumis melo var. conomon), cvs. Gaucho Redondo, Gaucho Comprido, Redondo Amarelo, Gulfcoast, Chilton, Bonus no. 2, Fantasy; watermelons: cv. Charleston Gray, Progenie da Coreia (Citrullus lanatus); pumpkins: cvs. Mra. Ma, Ornamental, Howden, Mammoth, Kururu, Goianinha (Cucurbita moschata); gourd: Abobora de Porco, cvs. Maranhao, Brasileirinha (Lagenaria siceraria); squash: cv. Pataca Gigante (Cucurbita maxima); cucumber: cvs. Caipira, Branco Meio Comprido, Curumim (Cucumis sativus); loofah: Metro, Semente Branca, Semente Preta (Luffa cylindrica); wax gourd (Benincasa hispida); pumpkin rootstock: Hybrid cv. Keij; snake gourd (Trichosanthes cucumerins) and musk cucumber (Sicana odorifera). To evaluate the resistance, seedlings were transplanted to pots and the root inoculated with 3,000 eggs and second stage juveniles of M. incognita and M. javanica. Fifty days after the inoculation, the plants were evaluated for nematode resistance by means of the reproduction factor. The grafting compatibility between net melon cvs. Bonus no. 2 and Fantasy and the rootstocks previously characterized as resistant were evaluated by means of 60 graftings. CNPH 01-962, CNPH 01-963 and melon 'Gaucho Redondo', were considered resistant to M. incognita. Melon 'Redondo Amarelo', watermelon 'Charleston Gray', watermelon Progenie da Coreia, Trichosanthes cucumerins were considered resistant to M. javanica. Benincasa hispida was resistant to M. javanica and M. incognita. The compatibility between net melons and resistant rootstocks was higher than 98%.
