Avaliação in vitro da resistência adesiva de braquetes ortodônticos variando-se o tempo de armazenamento e o tipo de fotoativação: luz halógena e led

O objetivo deste estudo in vitro foi comparar os efeitos da fotoativação pelos sistemas luz halógena e LED na adesão de braquetes ortodônticos em diferentes tempos pós-colagem (imediato, 24h e 7d). Braquetes com adesivo pré-aplicado (Gemini series; APC adhesive precoated brackets; 3M Unitek, USA) foram colados na superfície vestibular de dentes bovinos. O esmalte dos dentes foi condicionado utilizando-se o primer auto-condicionante (Transbond SEP, 3M Unitek, USA) em todos os espécimes, conforme recomendações do fabricante. Setenta e dois dentes foram divididos em 2 grupos (n=36), conforme o sistema de fotoativação (luz halógena ou LED) e sub-divididos (n=12) de acordo com o tempo pós-colagem. Para os grupos luz halógena, o tempo de fotoativação foi de 20s e para os grupos LED foi de 10s. O teste de resistência ao cisalhamento foi realizado com auxílio de uma máquina de ensaios universal nos diferentes tempos pós-colagem: imediato, 24h e 7d. O valor médio de adesão para os grupos luz halógena foi de 20,01±5,24MPa e, para os grupos fotoativados pelo sistema LED 17,35±5,07MPa, sendo estes resultados estatisticamente diferentes. Quando comparado o efeito do tempo pós-colagem, os resultados revelaram que os valores de adesão foram significantemente maiores para o tempo de 7d. O resultado do teste ANOVA 2 – fatores revelou não existir diferença estatística entre a interação sistema de fotoativação e tempos pós-colagem. O teste de Tukey mostrou que para as 4 condições experimentais nos tempos imediato e 24h, os resultados não diferiram estatisticamente, independentemente do sistema de fotoativação. Somente com relação ao grupo luz halógena-7d, os resultados mostraram diferenças estatisticamente significantes. O grupo LED-7d desempenhou comportamento intermediário entre os grupos. O índice de adesivo remanescente não revelou diferenças... (Resumo completo, clicar acesso eletrônico abaixo)

Análise da queda de granizo em Guarulhos-SP e seus impactos socioeconômicos

The climate and weather have direct implications on society, are factors that can to regulate or restrict human occupation in a determined space. In this way, studies of climate and weather are justified to be extremely necessary for urban planning and economic activities, especially agriculture. The precipitation of hail, which enters in the classification of severe storm, causes large, direct and indirect impacts on society, mainly when it occurs in urban areas. This work aims to study the precipitation of hail, explain what is a severe storms and how hail is formed in clouds, making use of a literature review in geography and also in weather sciences. It is also an aim of this work analyze the genesis, evolution and dissipation of a specific case of precipitation of hail occurred in the metropolitan region of São Paulo, especially in Guarulhos, on 21st of September 21 of 2010, through the use of GOES-12’ satellite’s images and the use of São Roque’s weather radar. And in this way, show the potential impact of hail storms in society and contribute to a greater preparedness of the population, urban planners associations and emergency management, such as municipalities, the civil defense and fireman

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

Profissão docente, vida decente: um estudo sobre o uso do tempo no cotidiano do magistério dos anos iniciais

This paper presents an approach to time perception in the daily elementary school teachers. The research was conducted with five teachers from the public system of the Rio Claro City, São Paulo State. The methodology chosen for the preparation of the research was based on two factors: literature review and content analysis. For the literature search were used books and scientific articles, as content analysis, based on information collected from responses of teachers, research subjects, the questionnaire prepared by the researcher, also counted with the testimony in the form of narrative of these teachers (P1). In the final considerations points that all respondents have the perception of scarcity of time to carry out numerous tasks related to the practice of teaching. Also highlighted is the fact that all respondents can not separate work and personal life, as many of the jobs are taken home by integrating everyday of individual teachers, that is, their time outside the classroom

Avaliação do tempo e da concentração do condicionamento com ácido fluorídrico sobre a resistência de união entre cerâmica e cimento resinoso

The aim of this study was to verify through microtensile test the influence of time and concentration of surface conditioning with hydrofluoric acid and its interference in the adhesion of dual resin cement to porcelain.We used 32 bodies of glass-ceramic lithium disilicate system IPS e.max Press LT with dimensions of 6mm thick, 8 mm in length and 8 mm in length, which will be molded to obtain composite resin blocks corresponding to blocks ceramics. Ceramic and resin blocks were divided into 16 groups (n = 4) and numbered according to the concentration of hydrofluoric acid (2.5%, 5%, 7.5% and 10%) and conditioning time (20 seconds, 40 seconds, 1 minute and 2 minutes). The blocks were cleaned in ultrasonic apparatus with distilled water and dried with compressed air, subjected to acid etching and air-jet washed with water, dried with compressed air and received application of silane agent Monobond-S, followed by adhesive Excite ( Ivoclar Vivaden). Each ceramic block was bonded to the corresponding block of resin through the resin cement Multilink Automix. The specimens were cut to obtain nine micro samples for each set of ceramic-resin with 1 mm X 1 mm X 12 mm in length, which were submitted to microtensile test. The results were analyzed with descriptive statistics and analysis of variance with significance level of 5%, revealing that there were statistically significant (p = 0.000001 <0.05). From the Tukey test can be concluded that etching with hydrofluoric acid and 2.5% for 120 seconds gave the best bond strength, however, no statistical difference between the conditioning with the same acid in the concentration of 5.0% for 20 to 40 seconds

Simulação do tempo de descarga de caminhões graneleiros em uma estação de transbordo de carga em Porto Murtinho, MS

In the current decade, inter modal transport is widely discussed. In Brazil road transport is used in excess whereas there could be more focus and investment towards water transport. Water transport presents many benefits like being low cost and low maintenance. Sea and river ports today aren't capable of supporting Brazil's transport needs. Therefore, with this obstacle, this paper consists of an attempt of modeling and simulation of the process of unloading grain cargo from trucks, through simulation with ProModel software, to verify the necessity of installing more tumblers at the cargo unloading station in Porto Murtinho, MS

Estudo comparativo entre subestações ao tempo e subestações isoladas a gás

In this paper are compared two methods of deploying electrical substations, conventional type, when installed at open areas (Air Insulated Switchgear - AIS), and compact gas-insulated (Gas Insulated Switchgear - GIS) when installed inside buildings. With the expansion of urban centers, areas available for deployment of conventional substations become increasingly difficult to find in these locations. Also due to speculation in urban areas, it becomes feasible to install Gas Insulated Switchgear. This paper presents and evaluates criteria with advantages and disadvantages for application of the two methodologies, aiming to assist in decisionmaking moment of choice in deployment of Electric Power Substations in two scenarios. It is expected that at the end of this work, the criteria evaluated assist in this decision making

Influência do uso de hipoclorito de sódio 2,5% e extrato glicólico de sálvia 20% durante o preparo biomecânico sobre a resistência adesiva de retentores intra- radiculares: avaliação através do teste de push-out

The aim of this study it was to evaluate the use of irrigating solution used during root canal preparation on the adhesive cementation of prefabricated fiberglass pins. The bond strength between different regions of the root and the fiberglass pins cemented into the root canal were evaluated by push-out assay. For this study, 36 human teeth were used, all equally prepared. The irrigating solutions used for biomechanical preparation were: saline solution, sodium hypochlorite 2,5% and glycolic extract of salvia 20%. The dual cure resin cement was used for cementation of pins. After cementation, specimens were sectioned to give 3 slices of approximately 2 mm each (cervical, middle and apical), which were submitted to mechanical push-out test. Were performed ANOVA and Tukey's test with a significance level of 5%, for the analysis of mechanical test. Comparing the thirds we observed that the only solution that presented statistical difference in the bond strength was sodium hypochlorite, which showed higher values for the middle and apical third compared with the cervical third, but when compared without taking into consideration the dental thirds, solutions studied showed no differences in bond strength. Therefore, it was concluded that the solutions studied can be used during endodontic treatment without causing harmful effects on the final adhesive restoration

Qualidade microbiológica de lanches e salgados comercializados em Botucatu, SP

A entrada das mulheres no mercado de trabalho, a dificuldade de locomoção do local de trabalho até a residência, a falta de tempo para o preparo das refeições e o preço mais acessível fez com que a escolha por lanches e refeições rápidas tenha crescido muito, nos últimos anos. Entretanto, esses alimentos estão sujeitos a contaminação desde seu preparo até o momento do consumo, além da manutenção em temperaturas inadequadas. Assim, o objetivo do trabalho foi avaliar microbiológica lanches e salgados comercializados em lanchonetes, “lojas de conveniência” e trailers das principais áreas da cidade de Botucatu, deacordo com os padrões estabelecidos pela ANVISA (RDC N º 12, 2001). As análises foram realizadas de acordo com o Compendium (APHA, 2001). Foram analisadas 122 amostras de salgados de carne, coxinhas, risoles de queijo, camarão e palmito, enrolado de salsicha além de salgado de frios e sanduíches, das quais 17 (13,9%) excederam aos limites microbiológicos. Excesso de coliformes termotolerantes foram encontrados 2 coxinhas, 2 risoles de palmito e 6 salgados de carne, no total de 10 amostras (8,2%). A presença Salmonella spp. foi detectada em duas amostras (1,6%) e clostrídios sulfito redutores apresentaram concentrações acima dos limites em somente uma (0,8%) amostra de salgado de carne. Não foram encontradas amostras com excesso de Bacillus cereus. Staphyloccocus aureus foi observado em valores acima dos permitidos em 8 amostras (6,6%) (5 coxinhas, 2 risoles de frios e 1 salgado). A partir das amostras analisadas, os resultados obtidos indicam que a maioria dos salgados estava dentro dos limites microbiológicos estabelecidos pela ANVISA (2001). Entretanto, 9% das amostras apresentaram patógenos, expondo a população a riscos. É necessária maior vigilância das autoridades competentes e, principalmente, conscientização por parte dos vendedores

Utilização de gonadotropina coriônica equina em protocolos de inseminação artificial em tempo fixo em bovinos de corte

Current cattlemen must seek methods to maximum reproductive efficiency of their beef herds, making the business competitive and enhancing greater profitability. For the cow-calf producers, efficiency translates into more cows producing one calf every year. Fixed-time artificial insemination (TAI) is one of several technologies that producers utilize to reach this goal. Postpartum anestrus is one of the biggest obstacles to overcome in order to obtain suitable results at the end of the breeding season. The TAI protocols are efficient in re-establishing cyclicity in noncycling cows during the postpartum period, streamlining the use of labor on farms, allowing the use of artificial insemination (AI) on a large scale, and introducing superior genetics to the herd. The protocols that are most commonly used in Brazil are based on progesterone (P4) releasing devices that prevent premature estrus and ovulation; and estradiol (E2) to synchronize the initiation of a new follicular wave. In such protocols, administration of equine chorionic gonadotropin (eCG) helps the development of the follicle, increases ovulation rate, improves the endocrine and uterine environment during proestrus and diestrus, and improves fertility. The use of eCG in TAI protocols for suckled cows, non-lactating cows and heifers increases the pregnancy rate allowing more calves at the end of the breeding season and higher profitability to the cattlemen
