The main objective of this study was to analyze the behavior of variables related to swim ability at and above maximal lactate steady state (MLSS), performed at continuous and intermittent conditions in individuals with different aerobic performance levels. Participated of this study male swimmers with ages between 20 to 25 years, specialists in events of 400 m, 800 m and 1500 m and open water swims, with at least 3 years of experience in the modality. The individuals performed a maximal 400-m swim test. After this test, they were divided into two groups, in accordance with the speed attained during 400-m swim test: G1 (higher performance) and G2 (lower performance). For the determination of continuous MLSS (MLSSc), 2 to 4 trials of 30-min were performed. For the determination of the intermittent MLSS (MLSSi) 2 to 4 trials of 30-min (12 repetitions of 2 min 30 s, with 30 s of rest) were performed, in constant speed, with the first trial performed at 102.5% MLSSc. Th technical indexes, stroke rate (FB) and stroke length (CB) were determined in all tests. The SR was calculated trough recordings using the time needed to perform five stroke cycles. The SL was calculated dividing the speed by the SR. There was no significant difference on the antropometric characteristics between groups. The speed at and above MLSSc were significantly higher at G1 (1,23±0,05 e 1,27±0,06, respectively) than G2 (1,10±0,06 e 1,13±0,06, respectively). There was significant change in SL and SR in G2. In the same way, there was significant change in SL and SR only in G2, above MLSSc. Similar to continuous condition, the speeds at and above MLSSi were significantly higher in G1 (1,27±0,05 e 1,30±0,05, respectively) do que no G2 (1,14±0,07 e 1,16±0,07, respectively). There was significant change in SL and SR only in G2. There was significant change in SR and SL in both groups above MLSSi. Thus,...(Complete abstract click electronic access below)

Steam generation plants have several industrial applications, being important for the national and global energetic matrix. Operational knowledge of steam plants is extremely important to forming a Mechanical Engineer. The facilities from Faculty of Engineering of Guaratingueta have a no operated steam pilot plant, named Thermal Machine Lab. Nowadays, the Energy Department from the faculty cannot explore this lab for its classes, even being essential to consolidate the theoretical concepts with tests simulating industrial applications. The goal of this project was to restore the operational condition of equipment of steam laboratory by fixing the equipment, and creating operational scripts for them. In a close future this lab could be used for classes, research and other applications

The objective of this study was to compare the power corresponding to maximal lactate steady state determined through continuous (MLSSC) and intermittent protocol with active recovery (MLSSI). Ten trained male cyclists (25 ± 4 yr, 72.5 ± 10.6 kg, 178.5 ± 4.0 cm), performed the following tests on different days on a cycle ergometer: (1) incremental test in order to determine the anaerobic threshold (AT) and maximal power (Pmax); (2) two to five constant workload tests to determine MLSSC, and; 3) two to three constant workload tests to determine MLSSI, consisting on 8 x 4 minutes bouts interspersed by two minutes of active recovery at 50% Pmax (i.e., 46 min of exercise protocol). MLSS intensity was defined as the highest workload at which blood lactate concentration did not increase by more than 1 mM between minutes 10 and 30 of the constant workload. The workload corresponding to MLSSC (273.2 ± 21.4 W) was significantly lower than that corresponding to MLSSI (300.5 ± 23.9 W). With base on these data, it can be verified that the intermittent exercise mode utilized in this study, allows an increase of 10% approximately, in the exercise intensity corresponding to MLSS.

Flebotomíneos (Diptera, Psychodidae) são incriminados na transmissão das leishmanioses. A criação destes insetos em laboratório é considerada complexa, porém é importante para que testes na área de comportamento e ecologia química sejam realizados. Um dos ramos da chamada ecologia química, avalia compostos voláteis, os quais podem ser liberados por hospedeiros ou sintetizados em laboratório, com poder atrativo para insetos hematófagos. Vem sendo bastante estudada para o grupo dos culicídeos, mas para flebotomíneos estes estudos ainda são escassos. Neste estudo foi feito o estabelecimento da colônia da espécie Lutzomyia (L.) longipalpis, coletados em Ipecaetá - BA, importante vetor da leishmaniose visceral nas Américas, e realizado testes de atratividade utilizando alcoóis (1-octen-3-ol, 1-octanol, 1-heptanol e 1- nonanol), em túnel de vento no laboratório de Parasitologia da Faculdade de Ciências Farmacêuticas - UNESP, campus de Araraquara. Os testes foram feitos com fêmeas e machos, da colônia previamente estabelecida. Os resultados mostraram que as fêmeas apresentaram melhor resposta para os compostos nonanol e octenol e os machos para os compostos octenol, nonanol e heptanol.

Committed to a functionalist view of grammar, this study takes word classes as its object of analysis, aiming to show that categorical rigidity cannot be upheld in linguistic use. The analysis sample presented starts from the solutions of dictionaries in the registration of word classes parts and from the fluidity that these classes show in their use. Aspects of grammaticalization in Portuguese language are taken as evidence. It is argued that the grammatical organization of language has properties that support categorical shift processes, however singular they may seem to examination.

In recent years, the concept of art education has been changing substantially the artistic and cultural education in the Brazilian educational system, particularly in relation to the formation of a critical awareness and practice of citizenship. In this process, the Community Public Relations and Public Communication excel in fostering alliances between government and community. Based on literature review and authors debates, such as Geertz, Santos, White, Freire, Araujo, Barbosa, Kunsch e Peruzzo. Besides the analysis of important materials, official documents and Brazilian projects involving art, culture and education, such as Research-Action Report 2013, the National Plan for Culture, the National Education Plan and the Municipal Act 6119; this paper seeks to explicit this affirmation, assuming the social transformation aiming a full citizenship, as a motivational factor. In this paper we also present a plan that includes a project in art education for the Stable Dance Company and the public elementary schools in Bauru SP

In studies about the subjectivation process in contemporaneity and the social context in which one is inserted nowadays, the contemporary world is often characterized by the ascension of the narcissism – or individualism – and consumerism as a baseline to all other recent changes. The excessive valorization of aesthetics; the influence of media and marketing and the culture of image; the loss of the “inner side” and inter-human interchanges; against the exacerbation of the superficial and external, appear as essential transformations to the new configuration of the so called “post-modern” subjectivation process, privileged and reinforced by capitalist society. Next to them, exists an individual discontent – a malaise in the individual’s life – usually associated to an interior emptiness and general dissatisfaction in face of idealizations and self-esteem fluctuations. This work tries to understand how individuals establish affective bonds and social relationships in this contemporary context, connecting the contemporary context and relevant concepts to this study, including the idea of romantic love, narcissism and the “state of helplessness” in psychoanalysis, subject’s development and a parallel discussion with social-historical texts. The study, of a theoretical character, is located in the intersection between "individual" and "society" – a subjectivity, therefore, formed internally, within the individual, and submitted directly to social influence – and analyzes the determinants and influences that they exert upon one and another, based on critical-reflective readings and textual analysis of works in the fields of sociology, psychosociology and psychoanalysis.

The present study focuses on the presence of covert contrasts in the speech of children with a phonological disorder. The hypothesis is that children with phonological disorders manipulate secondary acoustic cues in an attempt to distinguish the phonological contrasts. We used five audio recordings of the speech of five children with speech disorders, between four and five years of age, who showed the so-called “phonic substitution” involving the sound group of the fricatives. The data were edited and analyzed using the software PRAAT. A phonetic transcription of the first repetition of each child was performed by three evaluators, reaching a 66% agreement level. After the transcription, we carried out a contrastive phonological analysis of the production of the five children and, finally, an acoustic analysis of all the “substitutions”, based on six parameters. We discovered the existence of covert contrasts in the productions auditorily regarded as homophones by the evaluators, representing a total of 54% of total substitutions identified through an impressionistic approach by the evaluators. Children with phonological disorders are seen to rely on secondary acoustic cues in an attempt to distinguish fricative phonemes. The data obtained in this study allow us to reflect on the importance of considering the phonetic detail within the phonological models.

A Pesquisa Operacional (PO) oferece ferramentas, usando modelos matemáticos, que descrevem situações do mundo real das empresas e do governo. Estes modelos permitem otimizar lucros ou minimizar custos através da Programação Linear (PL), considerada a maior descoberta da matemática aplicada do século XX. Sua aplicabilidade é imensa e a programação computacional é simples. Por exemplo, o uso de software como o Excel, garante encontrar a solução para problemas que podem envolver um número grande de variáveis e assim auxiliar os agentes na tomada de decisão. Vários Prêmios Nobel em Economia tiveram a PL envolvido em seu conteúdo, por exemplo, os prêmios dados a Leonid Kantorovich, Leonid Hurwicz, Tjalling Koopmans Kenneth, Kenneth J. Arrow e Robert Dorfman, Paul Samuelson e Robert Solow. A Teoria das Filas, utilizada neste trabalho, é uma ferramenta da PO que envolve distribuição de probabilidades e permite investigar a chegada e atendimento de clientes, a partir de certos números de canais disponíveis. O caso em análise é uma fila do caixa rápido do supermercado Oba Hortifruti, localizado na cidade de Indaiatuba - São Paulo. A fila possui característica M/M/1, no qual o primeiro M denota que a chegada de clientes à fila segue uma distribuição de Poisson, o segundo M denota que o tempo de atendimento dos clientes segue a distribuição Exponencial e o 1 significa que há apenas um canal de atendimento. A aplicação desta ferramenta sugere uma otimização do serviço para que o mesmo se torne estável (objetivo qualitativo), gerando assim uma maior satisfação do cliente com o atendimento, podendo elevar a margem de lucro do estabelecimento em estudo (objetivo quantitativo)

The system consortium of grain crops with forage plants allows the establishment of pastures resistant, vigorous and lower cost in areas infested with stink bug brown root. Maize has favorable characteristics for intercropping as high plant height and insertion height of the studs, allowing the crop to occur without interference of forage plants. Furthermore, the production system in consortium with Bt corn reduced the infestation of Spodoptera frugiperda and was not affected by Scaptocoris carvalhoi (Hemiptera: Cydnidae), The Panicum maximum cv. Massai allowed a consortium with excellent corn and pasture provided a vigorous and excellent leaf mass distribution and very deep roots in the soil. Grain yield for Bt corn was higher and significant (P <0.05), compared to other treatments. The use of Lorsban (1.5 liters / ha) and Thiodan (2.0 liters / ha) was highly effective (P <0.05) in the control of Spodoptera frugiperda and Scaptocoris carvalhoi (Hemiptera: Cydnidae).
