Twenty eight boys (9.47 ± 0.64 years and thirty girls (9.69 ± 0.70 years were evaluated. The correlation values between agility and velocity on 5, 10 and 25 m velocity were, respectively, r = 0.63, 0.51, 0.44 and 0.64 with vertical jump, r = 0.68, 0.62, 0.28 and 0.62 with sextuple jump, and r = 0.60, 0.50, 0.26 and 0.57 with horizontal jump. The vertical and sextuple jumps were able to predict the agility and 25 m velocity performance (p < 0.05. Furthermore, they demonstrated capacity to predict 5 and 10 m velocity, respectively (p < 0.05. The vertical and sextuple jump tests may be used for assessment and control of training with children practicing activities that require agility and velocity, since both jumps predicted the agility and velocity performance, which did not occur with the horizontal jump.

Participaram 13 voleibolistas do sexo feminino (15,6 ± 0,9 anos. Inicialmente foi realizado um protocolo de potência máxima (três saltos máximos, seguido do protocolo de resistência de saltos (ciclos de três saltos máximos em aproximadamente 10 segundos (s - um salto a cada três s, com recuperação de 15 s. O tempo de duração do protocolo de resistência foi de 20 minutos. Foi usada a técnica do salto com contramovimento sem ajuda dos braços, sobre tapete de contato. Para tratamento dos dados os saltos foram divididos em quatro períodos com 12 ciclos cada um. Os resultados mostraram queda na altura dos saltos de aproximadamente 1,3cm entre os períodos de 1 a 4, sendo que, essa queda foi mais significativa nos 3º e 4º períodos em comparação ao 1º e 2º. Entretanto, com relação às variáveis RMS e FM, não ocorreu alteração nas respostas eletromiográficas entre músculos e períodos. Concluiu-se, assim, que a fadiga pode depender de variáveis psicofisiológicas, ao nível do SNC, que também influem no desempenho.The purpose of this study was to analyze the performance and the electromyographic responses of the muscles Rectus Femoris, Biceps Femoris and Gastrocnemius Medialis during vertical jumping protocol.

    Full Text Available INTRODUÇÃO E OBJETIVO: Na prática do voleibol, as entorses de tornozelo representam 25 a 50% das lesões agudas. Medidas preventivas, como estabilizadores dinâmicos de tornozelo (EDT, são frequentemente utilizadas, porém, há controvérsias se esse dispositivo pode ou não interferir no desempenho esportivo. O objetivo deste estudo foi analisar o efeito do EDT Active Ankle System® (AAS na altura do salto vertical em jogadoras de voleibol. MÉTODOS: Selecionou-se uma amostra de conveniência de 14 atletas entre 14 e 18 anos de idade, do gênero feminino. Estas foram instruídas a saltar simulando o gesto esportivo do ataque e do bloqueio com e sem o EDT, sobre placas de contato conectadas a um computador portátil que, através de um programa, calculava a altura do salto vertical. Previamente, foi feito um estudo-piloto para determinação do coeficiente de correlação intraclasse para as quatro condições de teste (n = 4, no qual os valores encontrados foram: ataque com EDT, 0,95; ataque sem EDT, 0,76; bloqueio com EDT, 0,92; bloqueio sem EDT, 0,89. Os dados de altura de cada tipo de salto vertical nas condições com e sem EDT foram comparadas através de testes t de Student para amostras pareadas. RESULTADOS: Para um nível de significância de α = 0,05, não foi encontrada diferença significativa entre os saltos do ataque com o EDT (0,41 + 0,073m e sem o EDT (0,41 + 0,086m, p = 0,517. Também não foi encontrada diferença significativa para os saltos do bloqueio com o EDT (0,31 ± 0,048m e sem o EDT (0,32 ± 0,050m, p = 0,06.

Para el control de la intensidad se han utilizado tres protocolos de saltos verticales con participación de brazos: a saltos verticales partiendo desde la posición de erguidos (CMJ + S; b partiendo de un salto previo donde la altura de caída estaba regulada por el participante (DJ-AR, y c partiendo de un salto previo máximo (DJ-M. Han participado 28 deportistas practicantes de modalidades deportivas donde el salto vertical constituye una habilidad básica. Se ha utilizado una plataforma de fuerza, operando a 500 Hz, sincronizada temporalmente a una cámara de vídeo, que registraba a 210 Hz el plano sagital de los saltos realizados sobre la plataforma. La aceleración vertical del CM se determinó a partir de la fuerza neta vertical y la masa del saltador. A continuación, los sucesivos registros de la velocidad vertical y las posiciones de componente vertical adoptadas por el CM se determinaron mediante integración de las componentes verticales de las funciones de aceleración-tiempo y velocidad-tiempo, respectivamente. Las constantes de integración se determinaron mediante imágenes de vídeo (2D.

    Full Text Available Con el propósito de analizar los cambios de la fuerza máxima explosiva en relación a la ejecución de series de salto vertical repetido (SVR con periodos cortos de recuperación pasiva en jugadores de baloncesto, se evaluaron 12 deportistas en un protocolo de cuatro series (S de 15-s de saltos verticales con 10-s de recuperación entre S. Se midieron la altura de salto inicial (ASI y final (ASF de cada S; se utilizó ANOVA de una vía con post hoc de Bonferroni para el análisis de las diferencias ASF-ASI por S y una prueba t de Student para analizar el índice de fatiga (IF por serie. Se encontró que la diferencia ASF-ASI fue progresivamente incremental desde la S1 hasta la S4 (-2,8 ±6,2 cm, -6,8 ±4,9 cm, -8,4 ±5,6 cm y -9,3 ±5,9 cm, respectivamente, aunque la diferencia fue mayor solo en S4 con respecto a S1 (p=0,014. Es posible que los períodos de recuperación entre cada S influyeron en el mantenimiento de la fuerza muscular explosiva (FME durante los primeros 45-s de saltos, sin embargo, la suma de estas ejecuciones generó un aumento de la fatiga al final de la prueba. La FME puede ser afectada por la suma de ejecuciones de SVR aun con la inclusión de períodos cortos de recuperación entre series. La relación trabajo-recuperación en baloncesto es un factor que debe considerarse para planificar el entrenamiento en jugadores de baloncesto.

    The purpose of this study was to value the immediate effect on the capacity of vertical jump, caused by the execution of continuous jumps in a trampoline. Nine subjects (23,4 ± 2.83 years, males and sportsmen with prior experience in the execution of countermovement jump (CMJ, they carried out a series of continuous vertical jumps on a trampoline during 60 seconds, being valued the capacity of jump in platform of contacts before and after this activity. The electromyographic (EMG activity was registered of five muscles of the right leg (gluteus, biceps femoris, vastus lateralis, gastrocnemius medialis and soleus in all the CMJ. The height of jump diminished significantly (p <0.01 after the execution of the jumps in the trampoline, being recovered in a brief period of time. Themselves differences were not observed in the EMG for the root mean squared (RMS or in the amplitude in none of the muscles, neither in the phase of impulse, neither in the 50 ms previous to start of the jump. In the neuromuscular pattern, in spite of the great variability existing inter and intraindividual, a significant delay was identified (p<0.05 in the activation of the biceps femoris immediately after the trampoline. Keeping in mind these results, seems probably that the smaller height of the vertical jump reached after the trampoline be more attributable to a modification in the temporary characteristics and sequence of activation of the muscles that to a decrease in the activation of the same.

    Full Text Available El propósito ha sido realizar un análisis dinámico y cinemático sobre los saltos verticales (SV y horizontales (SH y cuantificar la aportación de los segmentos corporales al desplazamiento del centro de masa (CM durante la fase de propulsión. Han participado 28 deportistas practicantes de modalidades deportivas donde el salto vertical constituye una habilidad básica. Se ha utilizado una plataforma de fuerza, operando a 500 Hz, sincronizada temporalmente a una cámara de vídeo a 210 Hz que registraba el plano sagital de los saltos. Los saltos han sido considerados como un movimiento simétrico que se desarrolla en un plano, compuesto por un modelo mecánico coordinado simplificado de ocho segmentos. En la condición SV, los participantes debían de realizar un salto vertical máximo partiendo de una posición erguida sobre la plataforma de fuerza. En la condición SH, los participantes debían realizar un salto máximo en horizontal desde la misma posición. El tiempo de batida ha sido superior en SH con respecto a SV, (0.898 vs 1.056 s, constatándose una estrategia de rotación-extensión para SH. Los resultados ponen de manifiesto que la fuerza neta ejercida durante el impulso de frenado es mayor para SV debido a la mayor velocidad radial al inicio del impulso de frenado (-1.166 vs -0.992 m/s. Existe una mayor participación de las articulaciones del tobillo y la cadera plasmada en la mayor contribución del tronco en SH durante toda la batida, además de constatarse una mayor contribución de las extremidades superiores al desplazamiento vertical del CM en SV.

    RESUMEN

    Registrar el tiempo de vuelo (Tv en una plataforma de contacto es una metodología muy utilizada para estimar la altura del salto vertical. Los objetivos del trabajo son: a-analizar si el tipo de plataforma de contacto influye en el Tv, y b-comprobar la validez y fiabilidad de una nueva plataforma de contacto de tipo optoeléctrico. 89 estudiantes realizaron 3 saltos verticales máximos registrados simultáneamente en una Plataforma de Fuerzas (PF y dos plataformas de contacto: ErgoJump Plus (EJ y SportJump System Pro (SJ, en los sentidos longitudinal y transversal respecto a PF. EJ subestimó el Tv en 50.8 ms, mientras que SJ lo subestimó en 10.6 ms. La altura del salto no influyó en estas diferencias, aunque fueron mayores para EJ cuando se saltó en sentido transversal. La relación PF-EJ (r=0.6597 fue menos alta que PF-SJ (r=0.9992. El coeficiente de variación fue mayor en EJ (6.61±4.81%* que en SJ (1.21±0.81% y PF (1.19±0.78%. El tipo de plataforma de contacto (optoeléctrica vs. mecánica influye sustancialmente en el Tv y la altura del salto vertical, por lo que estos dispositivos deberían ser validados antes de ser utilizados en estudios científicos. El nuevo sistema SJ que incorpora tecnología láser, ha resultado válido y fiable para medir saltos verticales.

    ABSTRACT

    The purpose of the present study is to determine the effect of two types of strength training on the different manifestations of dynamic force in which light loads (repetitive jumps and heavy loads are combined (Squat 70% of the 1RM. The study sample was selected from the Spanish Army (n=30: 15 males in each group, 22 ± 4 years of age, for which no control group existed. The reason for the lack of group control is sufficiently verified by scientific literature demonstrating that strength training produces significant gains in the height of the jump. The manipulated independent variable is the form of combination of the loads. In group 1 the combination of loads is made in the same set, and in group 2 the combination of loads is made in different sets, thereby determining which method, of both used, is more effective. Procedure: Both experimental groups trained 3 times per week, during 8 consecutive weeks. The intensity of the training and the load were the same for both groups. The

    The aim of this study was to find out if it is possible to predict the height of the vertical jump from kinematic, dynamometric and anthropometric variables using a multiple linear regression model. Fifty-three subjects, 21 male and 9 female volleyball players of first National categories (First National League and First League, as well as 23 Physical Education students (12 males and 11 females participated in this study. First, the height of the flight during the performance of a "squat jump" (SJ and "countermovement jump" (CMJ was determined. Then, the maximal isometric strength in the squat position was assessed with the knees bent at 90º, 120º and 140º while the electromyographic activity was simultaneously recorded on the vastus lateralis with surface electrodes. The muscle mass of the lower limbs was obtained by dual-energy X-ray absorptiometry (DEXA. The positive mechanical impulse explained on its own 77% of jumping height variability. Prediction power was increased to 82% by including in the model the percentage of body mass represented by de muscle mass of the lower limbs. The inclusion of the muscle mass of the lower limbs, as a third variable, raised the prediction power to 98% of jumping height variability. The same variables allowed for a similar level of prediction during the squat jumps.

    This paper aims to identify the influence that the delay of the second foot in a vertical jump with run up approach, has on the total impulse, impulse absorption, impulse acceleration, and on the percentage participation of each foot during the takeoff phase. Twenty three physical education undergraduates students participated in the study recruited among university basketball and volleyball players (mean height: 179 ± 6.1 cm; mean mass: 70.96 ± 8.82 kg. Two force platforms were used, one for each foot support (Dinascan – IBV at 250 Hz frequency and time-synchronized to one another and to a high speed video camera (Redlake Motion Space 1000 S. Results showed that the lower the time between the first and second contact foot, the lesser the takeoff time (p<0.001, although this reduction is only attributed to the negative period. The impulse of acceleration was not affected by the delay of the second foot, so that there would not be advantages regarding jump height. There is a bigger reduction of the horizontal velocity when the time between the first and the second contact foot is increased (p<0.01.

The sprint test consisted of a 30-meter run timed at the 10-meter and at the 30-meter marks. The jump capacity was assessed through the CMJ. Pearson's correlation (r was used to determine the association between these variables. The significance level adopted was p<.05. The U-20 players presented faster V10 and slower V20 than the professionals (p<.05. The correlation (r between CMJ and V10, V20 and V30 were .239, .370 and .408, respectively, for the U20 group and .381, .381 and .470, respectively, for the professional group. Evaluating the two categories together the correlation were; r= 0,293, 0,386 and 0,441 to V10, V20 and V30 respectively. The correlation between CMJ and V10 was weak and moderate for V20 and V30. In the professional category the correlation between CMJ and all the other parameters was moderate. It is probable that higher correlation values for CMJ and V10 for the professionals could be attributed to specific training effects.

    Full Text Available Em alta durante quase todo o século XIX, o prestígio dos naturalistas caiu nas últimas décadas do mesmo século, na medida em que o enfoque dos estudos biológicos transitava do histórico para o funcional. A redescoberta dos trabalhos de Mendel, em 1900, e a emergência da genética aceleraram este processo, onde a atividade do experimentalista substituía a anterior. Ao mesmo tempo, o darwinismo também declinava e os primeiros anos do século XX caracterizam o chamado "eclipse do darwinismo". Theodosius Dobzhansky, russo radicado nos Estados Unidos a partir de 1927, é o pesquisador que irá reunir as duas tradições, a naturalista e a experimentalista. No desempenho de suas atividades, ele realiza um verdadeiro salto qualitativo nos estudos de evolução em populações naturais, que pela primeira vez podem ser efetuados através do método experimental, auxiliados por um rigoroso planejamento teórico. Este artigo narra algumas etapas desta história.The high prestige naturalists had during most of the 19th century began to decrease in the last decades of that century, as the focus in biological studies switched from historical to functional. The rediscovering of Mendel's works in 1900 and the emerging of genetics made the process move faster and caused experimentalist activities to take over. Simultaneously, Darwinism was also losing ground and the first years of the 20th century were characterized by the so-called 'eclipse of Darwinism'. Theodosius Dobzhansky, a Russian researcher who moved to the United States in 1927, joined the two different traditional approaches, the naturalistic and the experimental ones. Through his activities, he accomplishes a quality leap for the study of evolution in natural populations, which can for the first time be carried out through experimental methods guided by thorough theoretical planning. This article narrates some of the steps of this story.

    Full Text Available Measuring the height of the vertical jump is an indicator of the strength and power of the lower body. The technological tools available to measure the vertical jump are black boxes and are not open to third-party verification or adaptation. We propose the creation of a measurement system called Chronojump-Boscosystem, consisting of open hardware and free software. Methods: A microcontroller was created and validated using a square wave generator and an oscilloscope. Two types of contact platforms were developed using different materials. These platforms were validated by the minimum pressure required for activation at different points by a strain gauge, together with the on/off time of our platforms in respect of the Ergojump-Boscosystem platform by a sample of 8 subjects performing submaximal jumps with one foot on each platform. Agile methodologies were used to develop and validate the software. Results: All the tools fall under the free software / open hardware guidelines and are, in that sense, free. The microcontroller margin of error is 0.1%. The validity of the fiberglass platform is 0.95 (ICC. The management software contains nearly 113.000 lines of code and is available in 7 languages.ResumenLa medición de la altura del salto vertical es un indicador de la fuerza y potencia del tren inferior.

    Full Text Available The hydroelectric exploitation of the Verdon stream, which is the most important of those flowing into the Durance river, is achieved by means of the Vinon Dam, and other dams. The combined water supply from the Greoux dam and the Vinon dam provide a controlled flow for the Provence canal, which is fed through the Maurras gallery. In this Alpine zone a general study is being conducted at present to coordinate in the best possible manner the use of the torrential water, available in the various valleys, both for irrigation and power producing purposes. The most important aspects of the Vinon project are the drilling of the very long galleries. This work has been done with very modem equipment of high efficiency. The author describes this in detail. The Vinon power plant is partly underground, and has a central cylindrical section, of 19 m diameter. This power station has a Francis unit, of 27.800 kw, operated by a water supply of 40 m3/sec under a hydrostatic head of 78 m.El aprovechamiento hidroeléctrico del arroyo Verdón, afluente más importante del río Durance, se realiza por medio del salto de Vinon. Las aguas combinadas de la restitución y embalse de Gréoux suministrarán un caudal regulado al canal de Provenza, para lo cual se aprovechará la galería de Maurras. Esta zona alpina es objeto, actualmente, de un estudio general que coordinará las aguas torrenciales de las distintas cuencas afectadas para un mejor aprovechamiento, tanto hidroeléctrico como para riegos, además de asegurar una regulación de caudales. Los trabajos más importantes del salto de Vinon se centran en la perforación de galerías de gran longitud, trabajo que se ha realizado con material moderno de gran rendimiento que el autor describe.

    Full Text Available Verifica-se precocidade na utilização de calçado de salto alto, mas não há muitos estudos identificando suas conseqüências. O objetivo deste trabalho foi verificar alterações de equilíbrio e eventual retração muscular em estudantes universitárias habituadas a utilizar salto alto diariamente. Foram avaliadas 30 jovens (média de 20 anos de idade que anotaram, durante duas semanas, o tempo diário em que permaneciam com o calçado. Foram avaliadas quanto a desvios posturais, quanto às retrações musculares da cadeia posterior, pelo teste de alcance horizontal, e quanto ao equilíbrio, pelo teste de Romberg. Os resultados foram analisados estatisticamente. A média de estatura foi 1,63 m e a de massa corporal, 58,5 kg. O tempo médio de uso dos sapatos de salto alto foi de 34 h por semana. Ao relacionar o alcance horizontal com o tempo semanal de uso do salto alto, verificou-se forte correlação negativa (r=-0,8692; pPrecocity has been noticed in the use of high-heeled shoes. However, there are not many studies on its consequences. The aim of this work was to search for equilibrium alterations in young women used to daily wearing high-heeled shoes. Thirty female undergraduates (mean aged 20 years old were asked to write down, for two weeks, the number of hours per day they remained with the shoes on. They were then assessed as to posture deviations, as to muscle retractions of the posterior chain by means of the sit and reach test, and as to equilibrium by the Romberg test. Results were statistically analysed. Mean volunteers' height was 1.63 m and mean body mass, 58.5 kg. A negative, strong correlation (r=-0.8692; p<0.0001 was noticed between reach range and weekly time (in hours of high-heeled shoe wearing.

    Full Text Available INTRODUÇÃO: A prática de exercícios de alongamento é muito comum como parte do aquecimento em diversas modalidades esportivas, porém, esta prática pode ser negativa para aqueles que desejam o aprimoramento da força e potência muscular, consequentemente, o rendimento dos saltos pode ficar reduzido após exercícios de alongamento, que depende do tempo de duração e intensidade do mesmo. OBJETIVO: Avaliar a influência do tempo de permanência no exercício alongamento sobre o desempenho do drop jump unilateralmente (unipodal. MÉTODOS: A amostra foi composta por 16 adultos jovens hígidos, com larga experiência em saltos. O protocolo de teste consistiu em realizar três drop jumps unipodais máximos a partir de uma plataforma de 15 cm sobre um tapete de salto (Hidrofit(r, antes e após duas durações (i.e. uma série 3 min. de um lado, e 6 min. para outro, a escolha foi de forma aleatória de alongamento dos músculos tríceps sural, utilizando uma intensidade entre 70-90% da percepção subjetiva de desconforto. A análise de variância ANOVA (2x2 foi utilizada para verificar diferenças para a altura de salto, tempo de contato e flexibilidade, utilizando um nível de significância de 5%. RESULTADOS: Apresentaram diferenças significativas entre condições pré e pós-alongamento para as durações de 3 e 6 minutos (P=0,002 e P=0,001, respectivamente, com a diminuição na altura máxima do salto. O tempo de contato foi maior apenas para a duração de 6 minutos (P=0,039. CONCLUSÃO: A realização de exercícios de alongamento do músculo tríceps sural por 3 ou 6 minutos de duração resulta na queda do desempenho do drop jump unipodal, diminuição da altura do salto vertical (para 3 e 6 min. de duração e tempo de contato (apenas 6' min., reforçando a necessidade de mais debates na área sobre exercícios de alongamento antes daqueles de potência.

    Full Text Available El entrenamiento del salto es fundamental para obtener un óptimo desempeño en diversos deportes, siendo el método complejo, basado en el fenómeno de potenciación posactivación (PPA, uno de los de los más utilizados para el entrenamiento de esta cualidad. Numerosos estudios respaldan la existencia de PPA representada en las variaciones de un salto vertical, sin embargo, en la literatura no se describe un protocolo estándar de entrenamiento que genere dicho fenómeno. Este estudio piloto cuantitativo cuasi experimental tiene como objetivo determinar en cuál de las zonas de fuerza descritas por Naclerio se debe entrenar para que la PPA se exprese, en mayor medida, evidenciado en las variaciones de altura de un salto Counter Movement Jump (CMJ. Se utilizó un muestreo por conveniencia de veinticinco individuos, divididos aleatoriamente en cinco grupos, cada uno correspondiente a una zona de fuerza. Luego los sujetos fueron entrenados con sentadilla media según los parámetros de cada zona. Finalmente, se obtuvo la altura del salto basándose en la fórmula de Bosco a partir de los fotogramas de una cámara digital. Existieron dos zonas de fuerza que presentaron un aumento en la altura del salto posterior a la potenciación, la zona de fuerza potencia y explosiva, sin embargo solo la primera de estas mostró resultados significativos en dicho cambio (p < 0,05, representados como un 7 % de aumento. Pretendemos que dichos hallazgos sean útiles para el desarrollo de nuevos estudios que permitan el diseño de nuevas metodologías de entrenamiento y rehabilitación deportiva viéndose beneficiados por sus propiedades.

    Full Text Available OBJETIVO: Revisar estudos referentes às repercussões do uso de calçado com salto alto na postura corporal de adolescentes. FONTES DE DADOS: Pesquisa realizada nas bases de dados Scopus, SciELO e PubMed entre 1980 e 2011, incluindo artigos escritos em inglês e português. Foram utilizados os descritores: "postura", "centro de gravidade" e "calçado de salto alto". Foram encontrados 55 artigos, independentemente do desenho do estudo, incluindo-se 20 relacionados à postura da coluna vertebral e membros inferiores, à localização do centro de gravidade e às repercussões do uso do calçado de salto alto no sistema musculoesquelético em adolescentes. SÍNTESE DOS DADOS: O uso frequente do calçado de salto alto acarreta modificação do centro de gravidade e do equilíbrio corporal, podendo ocasionar mudança no alinhamento dos segmentos corporais. Isso traz repercussões negativas ao desenvolvimento motor das adolescentes, pois nessa fase há a necessidade de manutenção da postura fisiológica para que ocorra o crescimento e o desenvolvimento do sistema musculoesquelético. CONCLUSÕES: O uso do calçado de salto alto por adolescentes pode favorecer o aparecimento de distúrbios posturais, dentre os quais se destacam anteriorização da cabeça, hiperlordose lombar, anteversão pélvica e joelho em valgo. Identificou-se que a altura e a largura do salto são as características do calçado que mais influenciam no surgimento de alterações posturais e desequilíbrio corporal.

    Full Text Available Este trabalho teve como objetivo avaliar o efeito do treinamento sobre as variáveis da cinemática de equinos jovens da raça Brasileiro de Hipismo no salto em liberdade. Foram utilizados 14 equinos da raça Brasileiro de Hipismo com idade de 40 a 42 meses, peso vivo de 436,3±11,6kg e 448,2±12,7kg e altura na cernelha de 1,57±0,03m e 1,58±0,03m ao início e ao final do experimento, respectivamente. Os equinos realizaram dois protocolos de avaliação de salto, um antes e outro após o treinamento. O treinamento teve a duração de cinco meses e consistiu em 50 minutos de atividade física por dia, montados, sendo dois dias de flexionamento, dois dias de condicionamento físico e dois dias de trabalho específico de salto de obstáculos. Nos protocolos de avaliação, foram filmados cinco saltos em liberdade sobre um obstáculo oxer, com o primeiro e o segundo elemento na altura de 0,90m e 1,00m de altura, respectivamente, e 0,90m de largura. Foram fixados marcadores reflexivos nos equinos em pontos anatômicos utilizados como pontos de referência para a avaliação das características cinemáticas no salto. As filmagens foram realizadas com câmera de 100Hz, e as imagens, processadas no Simi Reality Motion Systems (r. Os resultados das variáveis avaliadas foram comparados com o teste de t pareado (P0,05. Conclui-se que o treinamento específico para salto com cinco meses de duração altera algumas variáveis cinemáticas dos equinos no salto de obstáculo proporcionando melhoria, principalmente, na trajetória do salto.

    Full Text Available A intensa mobilização do solo no sistema cultivo convencional causou degradação da estrutura, compactação e adensamento do solo abaixo da camada arável, reduzindo a macroporosidade e a taxa de infiltração de água no solo, com conseqüente aumento de escoamento superficial, de erosão e de assoreamento de rios e de reservatórios. A semeadura direta, que protege a superfície do solo, praticamente controlou a perda por erosão hídrica, os terraços foram eliminados, pelos agricultores, e a conseqüência foi maior escoamento superficial do que no sistema cultivo convencional. Com o objetivo de avaliar o comportamento hidrológico do vertical mulching em semeadura direta, em relação ao escoamento superficial, realizou-se esta pesquisa nos anos agrícolas 2002/2003 e 2003/2004, em Latossolo Vermelho distrófico típico, na região fisiográfica do planalto médio do Rio Grande do Sul, isto é, um experimento em escala de campo, com parcelas sem vertical mulching, com vertical mulching a cada 10 m e com vertical mulching a cada 5 m, no delineamento de blocos ao acaso com três repetições. Sulcos em nível, perpendiculares ao declive, com dimensões de 0,08 m de largura por x 0,38 m de profundidade, foram abertos e preenchidos com palha compactada o suficiente para prevenir desmoronamento das paredes do sulco. No ciclo da cultura da soja e do trigo foram simuladas chuvas com duas intensidades, 70 e 106 mm h-1. Foram determinados o escoamento superficial, a taxa de infiltração básica de água no solo e a concentração de nutrientes e de CO no escoamento superficial. Os resultados indicam que o vertical mulching na semeadura direta reduz, significativamente, o volume do escoamento superficial aumenta a taxa de infiltração básica de água no solo e reduz também as perdas totais de nutrientes e de CO devido ao menor volume de água no escoamento superficial.Intensive soil mobilization in the conventional tillage system has caused

    Full Text Available FUNDAMENTOS E OBJETIVO: O segmento mais freqüentemente lesado no basquetebol é o tornozelo, sendo a entorse por inversão a lesão mais comum. Para evitá-la, é comum o uso de implementos. O objetivo deste estudo foi avaliar a força reação do solo (FRS em jogadores de basquete durante execução do salto em três situações: uso de tênis, bandagem e tênis, e tênis e órtese tipo Aircast. MÉTODOS: Oito atletas foram analisados durante o salto, através de uma plataforma de força, nas três situações citadas, para análise das componentes vertical e horizontal médio-lateral da FRS. RESULTADOS E CONCLUSÃO: Não houve diferença estatística significativa entre as três situações na componente vertical da FRS durante o salto, embora o uso de bandagem tenda a apresentar, na impulsão, maiores valores do pico de força vertical (3,10 ± 0,46PC; 3,01 ± 0,39PC; 3,03 ± 0,41PC e do gradiente de crescimento (GC (12,33 ± 12,21PC; 8,16 ± 3,89PC; 8,46 ± 3,85PC, e durante a aterrissagem, menores valores de pico de força vertical (5,18 ± 1,35PC; 5,56 ± 1,31PC; 5,49 ± 1,44PC e do GC (88,83 ± 33,85PC; 95,63 ± 42,64PC; 94,53 ± 31,69PC. Durante a impulsão, a força medial do salto com Aircast foi significativamente menor que com tênis (p = 0,0249 e apresentou valor semelhante ao do uso da bandagem, enquanto a força lateral foi significativamente maior com a bandagem do que com tênis (p = 0,0485 e tendeu a ser maior do que o Aircast. Na aterrissagem o componente médio-lateral da FRS ficou inalterado nas três situações. Concluiu-se que a bandagem potencializou a força direcionada ao salto vertical durante a impulsão, porém não estabilizou tanto quanto o Aircast os movimentos de inversão e eversão do pé. Durante a aterrissagem, os implementos não foram efetivos para reduzir a força médio-lateral, mas com a bandagem, houve um tempo maior para absorção do impacto.FUNDAMENTOS Y OBJETIVO: EL segmento mas frecuentemente

Para caracterizar a distribuição espacial da temperatura do ar no ambiente protegido, instalaram-se termopares (cobre-constantã formando malhas, com espaçamento horizontal entre eles de 3,0 m e nas alturas de 0,5, 1,0, 2,0, 3,0 e 4,0 m em relação ao solo. Os dados foram armazenados a cada 15 min por sistemas automáticos de aquisição de dados nos ambientes protegidos. O sistema de nebulização constituiu-se de duas linhas com 70 bocais totais, instalados a uma altura de 3,0 m, utilizando-se uma pressão de trabalho de 200 kPa. A nebulização não afetou o gradiente vertical de temperatura, que manteve a tendência de aumento de temperatura com a altura, em relação ao nível do solo, enquanto o efeito na redução de temperatura pelo sistema de nebulização somente foi eficaz durante a realização da mesma. Para a representação da distribuição espacial de temperatura do ar no ambiente protegido nos diferentes níveis de altura, construiu-se superfícies isotérmicas a partir dos resultados.

    Highlights: • SALTO peer review service is designed for reviewing of ageing management and NPPs’ preparedness LTO. • It has been established as an effective tool to review the compliance with IAEA safety standards. • The important issues for safe LTO are being identified by SALTO missions. • Analysis of those issues is provided in the paper. • This peer review service is strongly recommended for NPPs prior to entering LTO period. - Abstract: This paper presents main IAEA activities for safe long term operation (LTO) which includes establishment of IAEA Safety Standards and other LTO related documents, fostering information exchange and establishing databases and provision of SALTO (Safety Aspects of Long Term Operation) peer review service. This paper provides insights into IAEA SALTO peer review service objectives, scope and methodology. The SALTO peer review service was designed to assist nuclear power plant (NPP) operators in adopting a proper approach to LTO of their plants and in implementing complete and appropriate activities to ensure that plant safety will be maintained during the LTO period. The SALTO peer review service can also support regulators in establishing or improving regulatory and licensing strategies for LTO of NPPs. Issues derived from 19 SALTO missions and 2 LTO modules of OSART (Operational Safety Review Team) missions conducted during the period of 2005 to March 2014 are also analyzed in this paper.

    Full Text Available OBJETIVO: Descrever a prevalência de infecção por HIV em gestantes e a taxa de transmissão vertical, segundo o perfil socioeconômico dos bairros de residência das mães. MÉTODOS: Estudo ecológico exploratório utilizando a base de dados do Sistema de Informação de Agravos de Notificação de gestantes HIV-positivas e aids em crianças notificadas entre 2000 e 2006 em Vitória, ES. Para análise das informações socioeconômicas foi utilizado o Índice de Qualidade Urbana. A prevalência de HIV em gestantes e a taxa de transmissão vertical foram calculadas. A distribuição espacial dos casos foi realizada no programa Terraview 3.2.0. Para verificar a associação entre a qualidade urbana e a prevalência de HIV em gestantes utilizou-se o modelo de regressão de Poisson. RESULTADOS: Um total de 137 gestantes e 14 crianças infectadas por transmissão vertical foi notificado no período. Sete crianças correspondiam a mães HIV-positivas sem notificação de caso no período analisado. A prevalência de infecção em gestantes no período foi de 0,44% e a taxa de transmissão vertical foi de 9,7%. CONCLUSÕES: A prevalência de infecção por HIV em gestantes e a transmissão vertical associam-se à qualidade urbana do bairro de residência, indicando que os bairros com menor qualidade urbana devem ser priorizados quanto às ações para redução da transmissão vertical.

    Full Text Available O objetivo do presente estudo foi comparar os efeitos do treino de força (TF e do respectivo destreinamento entre dois modelos de periodização do volume (linear - ML; não linear - MNL em jovens voleibolistas. A amostra foi composta por 12 jovens do sexo masculino jogadores de voleibol (17.1 ± 0.5 anos, divididos em dois grupos homogêneos. Os resultados sugerem que 8 semanas de TF induzem modificações significativas nos indicadores da força, independentemente do modelo de periodização utilizado. Contudo, o MNL parece menos eficaz no desenvolvimento da força explosiva em habilidades motoras específicas (salto vertical. Os resultados indicam que 4 semanas de destreinamento são suficientes para provocarem perdas significas na força muscular em jovens voleibolistas. O destreinamento de um ML induz a perdas significativas na força explosiva do trem superior (lançamento de bola medicinal e inferior (salto vertical, enquanto que no MNL parece diminuir significativamente a força dinâmica máxima (supino e o desempenho no salto vertical.This study aimed to compare the effects of strength training (ST and detraining (DT of two volume periodization models (linear - LM; non linear - NLM in young male volleyball players. 12 volleyball players (17.1±0.5 years old were randomly divided into two groups.

    The synthetic aggregates are being employed in civil construction for the reduction of mineral extraction activities. Within this context, the recycling of industrial waste is the basis of the majority of processes to reduce the exploitation of mineral resources. In this work the sintering in a vertical fixed bed reactor for synthetic aggregate production using 20% pellets and 80% charcoal was studied. The pellets were prepared from a mixture containing clay, charcoal and fly ash. Two experiments varying the speed of air sucking were carried out. The material produced was analyzed by X-ray diffraction, scanning electron microscopy, measures of their ceramic properties, and particle size analysis. The results showed that the solid-state reactions, during the sintering process, were efficient and the produced material was classified as coarse lightweight aggregate. The process is interesting for the sintering of aggregates, and can be controlled by composition, particle size, temperature gradient and gaseous flow. (author)

    Full Text Available BACKGROUND: There still are controversies concerning the vertical transmission of hepatitis C virus. AIM: To evaluate the prevalence of antibodies against hepatitis C virus in pregnant women, as well as the rate of vertical transmission of this virus. PATIENTS AND METHODS: Between August 1998 and November 1999, 1,090 consecutive pregnant women were screened for anti-hepatitis C virus; positive results were confirmed by the polymerase chain reaction assay. Patient's viral load was evaluated by the branched deoxyribonucleic acid assay. Hepatitis C virus genotype was identified by direct sequencing of the polymerase chain reaction amplification products. The same tests were performed in the children born from infected mothers at the 1st and 6th month of life. RESULTS: Of the 1,090 mothers surveyed, 29 were positive for anti-hepatitis C virus (prevalence of 2.66%. Twenty-five patients presented with hepatitis C virus RNA, with a median hepatitis C virus viral load of 3.132 ± 5.891 MEq/mL. Twenty-two patients (six human immunodeficiency virus-coinfected were followed and gave birth to 23 children; 18 of them had blood samples tested at the 1st month of life, and 22, at the 6th month. Vertical transmission rate was 5.56%; it affected a girl who had hepatitis C virus RNA detectable only in the 1st month sample (41.570 MEq/mL. The mother who transmitted hepatitis C virus was coinfected with human immunodeficiency virus and presented with an hepatitis C virus viral load of 3.765 MEq/mL, with 100% homology with her daughter's hepatitis C virus genotype. CONCLUSION: These results suggest that the prevalence of hepatitis C virus infection in pregnant women should not be neglected, and early diagnosis of vertical transmission and the follow up of infected children should be emphasized.RACIONAL: Ainda existem controvérsias em relação à transmissão vertical do vírus da hepatite C (VHC.

    Full Text Available Resumo Objetivo Analisar a capacidade preditiva da bioimpedância tetrapolar segmentada vertical na detecção do excesso de peso em adolescentes com o uso da bioimpedância tetrapolar horizontal como referência. Métodos Estudo transversal feito com 411 alunos de 10 a 14 anos, de ambos os sexos, matriculados em escolas públicas e privadas, selecionados por processo amostral aleatório simples e estratificados de acordo com sexo, idade e proporção em cada instituição. Foi feita avaliação antropométrica e analisada a composição corporal por meio das bioimpedâncias bipolar vertical, tetrapolar horizontal e tetrapolar segmentada vertical. Foram construídas as curvas ROC com base nos cálculos de sensibilidade/especificidade para cada ponto das diferentes medições possíveis de gordura corporal do equipamento em questão. Posteriormente, foram executados os seguintes testes estatíticos: t de Student, correlação de Pearson e qui-quadrado de McNemar. Para a interpretação das variáveis, usou-se o software SPSS 17.0. Resultados A amostra foi composta por 53,7% meninas e 46,3% meninos. Do total, 20% e 12,5% exibiram, respectivamente, sobrepeso e obesidade. Os gráficos das medidas dos segmentos corporais refletiram-se em altos valores de sensibilidade e especificidade, além de elevadas áreas sob a curva ROC, que variaram de 0,83 a 0,95 para meninas e de 0,92 a 0,98 para meninos, o que sugere um desempenho levemente superior para o sexo masculino. O percentual de gordura total foi apontado como o critério mais eficiente do equipamento para a detecção do excesso de peso, enquanto a gordura segmentar do tronco apresentou-se como um indicador de precisão inferior. Conclusão A aparelho comportou-se satisfatoriamente na predição do excesso de peso.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Os pacientes com doença pulmonar obstrutiva crônica (DPOC têm risco aumentado de complicações pós-operatórias, sobretudo quando submetidos à anestesia geral. O bloqueio do plexo braquial representa uma alternativa para estes pacientes em intervenções cirúrgicas de membros superiores. O objetivo deste relato foi apresentar um caso de bloqueio do plexo braquial, por via infraclavicular vertical em paciente com DPOC com fratura de cotovelo. RELATO DO CASO: Paciente do sexo feminino, 67 anos, 52 kg, estado físico ASA III, com indicação de osteossíntese de cotovelo, portadora de bronquiectasias desde nove anos de idade após uma pneumonia. Apresentava tosse produtiva habitualmente, e fora submetida à avaliação de seu pneumologista que a liberou para o procedimento. Após instalação de monitorização com pressão arterial não-invasiva, ECG e oxímetro de pulso, foi realizado bloqueio do plexo braquial por via infraclavicular vertical com 30 mL de ropivacaína a 0,5%. A intervenção cirúrgica foi realizada sem intercorrências. A paciente recebeu alta hospitalar no dia seguinte ao procedimento cirúrgico. CONCLUSÕES: O bloqueio do plexo braquial por via infraclavicular vertical é uma técnica alternativa para portadores de DPOC e fratura de cotovelo, por sua menor morbidade quando comparado com a anestesia geral e com a via supraclavicular.

    Uruguay is located at the southern border of Aedes aegypti distribution on the South American sub-continent. The reported dengue cases in the country are all imported from surrounding countries. One of the cities at higher risk of local dengue transmission is Salto, a border city with heavy traffic from dengue endemic areas. We completed an intervention study using a cluster randomized trial design in 20 randomly selected 'clusters' in Salto. The clusters were located in neighborhoods of differing geography and economic, cultural and social aspects. Entomological surveys were carried out to measure the impact of the intervention on vector densities. Through participatory processes of all stakeholders, an appropriate ecosystem management intervention was defined. Residents collected the abundant small water holding containers and the Ministry of Public Health and the Municipality of Salto were responsible for collecting and eliminating them. Additional vector breeding places were large water tanks; they were either altered so that they could not hold water any more or covered so that oviposition by mosquitoes could not take place. The response from the community and national programme managers was encouraging. The intervention evidenced opportunities for cost savings and reducing dengue vector densities (although not to statistically significant levels). The observed low vector density limits the potential reduction due to the intervention. A larger sample size is needed to obtain a statistically significant difference. © The author 2015.

    Full Text Available Este estudo teve por objetivo realizar o inventário arbóreo-urbano em 24 bairros do Município de Salto de Pirapora, SP, por meio da avaliação quali-quantitativa. Para tanto, foram obtidas informações relacionadas à: espécie arbórea, situação da copa e do tronco, orientação do tronco, fitossanidade, interceptação das raízes no passeio, necessidade de tratos silviculturais, altura total e altura da primeira bifurcação, assim como características do espaço viário. Foram registrados 868 indivíduos, dos quais 679 foram catalogados em 71 espécies arbóreas. A espécie de maior frequência foi Caesalpinia pluviosa, representando 13,6% do total, seguida de Ficus benjamin (10,4%, Lagerstroemia indica (5,0% e Terminalia catappa (4,8%. Quanto à condição do tronco, 68,8% dos indivíduos arbóreos não apresentaram problemas; 85,7% das árvores observadas possuíam orientação simpodial adequada; poucas árvores apresentavam danos relacionados à fitossanidade que poderiam interferir em sua integridade e, ou, longevidade; 69,6% não interferiam, de forma direta, na calçada; 32,8% das árvores necessitavam de podas por estarem acima da fiação elétrica; 0,5% necessitava de substituição; e 5,7% precisavam ser removidas. Com relação à altura total das árvores, 63,0% apresentavam crescimento menor que 5 m; e 65,3% com altura da primeira bifurcação do tronco inferior a 1,80 m. O Bairro Primavera destacou-se pelo maior número de árvores em sua urbanização. Em contrapartida, o Jardim Amélia apresentou apenas um indivíduo. Dessa forma, observou-se que cada bairro possuía sua particularidade, e ações de manutenção e enriquecimento, tanto relacionadas ao número de espécies quanto à quantidade de indivíduos, deveriam ser consideradas no planejamento urbano-arbóreo daquele município.

    Full Text Available Resumo Grande parte da dinâmica de crescimento urbano é motivada pela busca do lucro, o qual, por sua vez, está relacionado à localização, principal componente de valorização do solo. A verticalização é uma das estratégias para a maximização do lucro sobre o solo urbano. Em áreas onde o custo deste é alto, os promotores imobiliários tendem a intensificar a área construída e o número de pavimentos. O objetivo deste estudo é investigar as características configuracionais das vias em que aconteceu o processo de verticalização residencial em Florianópolis, no Estado de Santa Catarina. Para isso, utilizou-se a Teoria da Sintaxe Espacial, por meio de suas duas medidas principais, Integração e Escolha. Os resultados indicaram que a lógica de localização dos edifícios residenciais verticais (ERVs na cidade de Florianópolis está relacionada, principalmente, à medida de Escolha local (R3, ou seja, há maior concentração de ERVs em vias que canalizam fluxos utilizados para chegar às outras partes dentro de um sistema local, tornando sua localização localmente central. Entretanto, isso está também relacionado ao processo histórico de ocupação urbana, com áreas mais antigas e consolidadas mostrando tendência de ocupação dos ERVs em vias com maior Integração e Escolha até um determinado momento e posteriormente voltando-se para áreas mais interiorizadas do tecido.

    Full Text Available Fruto de uma pesquisa desenvolvida no âmbito do projeto Razão-Poesia a respeito da colocação dos poetas na sociedade e nos meios editorial e literário, este artigo tem por objetivo identificar posicionamentos éticos e estéticos de alguns poetas diante da visibilidade proporcinada pelos meios de comunicação. Fomos em busca de compreender a opção daqueles que qualificamos de “poetas da verticalidade” pela sua busca estética, e “poetas do desaparecimento” pelo seu posicionamento ético. Arthur Rimbaud e Roberto Juarroz tiveram duas maneiras diferentes de escolher o desaparecimento: a fuga para o estrangeiro e a discrição silenciosa. O primeiro transformou definitivamente a forma do verso pela intensidade da pulsação do seu dizer. O segundo não teve a mesma influência sobre a produção poética subsequente, mas compôs uma obra extensa e sistemática. A análise desses dois exemplos nos conduziu a pensar a liberdade do desprendimento como condição de possibilidade do exercício ético e estético.

    Full Text Available Este artículo desarrolla un modelo estocástico macroeconómico útil para explicar los efectos que tienen los saltos inesperados en el gasto de gobierno per cápita y en variables demográficas en el crecimiento económico per cápita. Para ello se supone que las dinámicas estocásticas del gasto público y de la población son conducidas por procesos de difusión con saltos modulados por una cadena de Markov. Los resultados más importantes son que los saltos bruscos e inesperados en el gasto público per cápita y en el crecimiento de la población impactan negativamente la tasa de crecimiento per cápita del producto. En particular, si hay un salto brusco y repentino en la tasa de crecimiento de la población, entonces el capital per cápita disminuye repentinamente impactando con ello negativamente el producto per cá- pita. Por último, los resultados teóricos encontrados se complementan con eviden- cia empírica del caso mexicano obtenida mediante un modelo que toma en cuenta tanto la volatilidad de las tasas de crecimiento de la población y del gasto público per cápita así como las sorpresas en la intensidad de los saltos en esas variables.

    Full Text Available OBJETIVO: Quantificar a relação entre o posicionamento do olho e das pálpebras, em diferentes posições do olhar, ao longo do meridiano vertical, em indivíduos normais. MÉTODOS: Foi quantificada a posição das pálpebras superior e inferior e do olho, de dez indivíduos normais, por meio do processamento da imagem da fenda palpebral usando o programa NIH Image. Foram medidas as distâncias margem-centro pupilar superior e inferior em sete posições do olhar ao longo do meridiano vertical, ou seja -30, -20, -10, 0, +10, +20 e +30 graus (sinais: negativos infraducção e positivos supraducção. RESULTADOS: Em relação à distância margem superior-centro da pupila, nota-se que o maior valor é obtido na posição primária do olhar, ou seja, tanto quando se olha para cima, como para baixo, essa distância diminui. A redução na distância margem superior-centro da pupila é um pouco maior no olhar para cima. Em relação à distância margem inferior-centro da pupila, nota-se que o valor é maior no olhar para cima e menor no olhar para baixo, em relação à posição primária do olhar. No que tange à fenda palpebral, pode-se notar que no olhar para cima a fenda aumenta até 20 graus de rotação ocular. No olhar para baixo, ela diminui. CONCLUSÃO: Os dados do presente trabalho mostram que a altura da fenda palpebral varia de acordo com a amplitude da mirada vertical e que considerações sobre o valor da magnitude da distância entre a margem palpebral e o centro da pupila devem levar em conta o grau de rotação ocular vertical.PURPOSE: To quantify the relation between eye and eyelids placement in different positions during downgaze and upgaze in healthy subjects. METHODS: The position of the eye and eyelids of 10 healthy individuals was quantified by palpebral fissure image processing with NIH Image software.

    Full Text Available O squat jump (SJ tem sido extensivamente usado para controlar o treino, contudo, estudos realizados em atletas treinados são escassos. Assim, a principal questão de estudo foi: quais os parâmetros de força que melhor podem explicar a performance do SJ em atletas treinados? Trinta e cinco atletas realizaram 3 SJ com uma barra de 17 kg. A força exercida contra o solo foi medida com uma plataforma sincronizada com um medidor linear de posição. Somente o melhor salto foi analisado. A análise do SJ foi dividida em duas fases: concêntrica 1 que foi definida desde o início do movimento até se alcançar a máxima velocidade positiva; e a concêntrica 2 definida o momento em que acaba a fase concêntrica 1 até se atingir a velocidade de saída. Não foi observada nenhuma relação entre a performance do SJ e o impulso durante a fase concêntrica 1. Todavia, observou-se uma correlação moderada mas significativa (r = .63 entre a altura do SJ e o impulso da fase concêntrica 2. Para além disso, uma associação moderada significativa (r = .56 foi igualmente observada entre o SJ e a força explosiva produzida durante a fase concêntrica 1. O SJ revelou ainda relações significativas com o pico de potência e potência média, mas somente durante a fase concêntrica 1 (r = .57. Em suma, é importante que os valores de força, de potência e de força explosiva sejam mantidos durante a fase inicial do salto, isto é, durante a fase concêntrica 1, promovendo uma maior impulsão vertical.

    Full Text Available Dentro de las habilidades deportivas, la capacidad de producir fuerza lo más rápidamente posible, o fuerza explosiva, juega el papel más importante en la optimización de dichas habilidades. Zatsiorsky (1995 la define como “la habilidad para desarrollar la máxima fuerza en la menor cantidad de tiempo”. Las correlaciones existentes entre pruebas de velocidad y tests de salto han sido ampliamente observadas. Sin embargo, las correlaciones entre pruebas de velocidad y tests isométricos están menos estudiadas. Una muestra de 24 velocistas de categoría junior fue sometida a pruebas de velocidad específica, tests de salto con contramovimiento y en profundidad, así como a un test isométrico máximo para la musculatura extensora del tobillo. Los resultados muestran fuertes relaciones entre los tests de carrera y los de salto, así como de estos últimos con los de dinamometría. Por otro lado, sólo con el test de 20 metros se obtienen correlaciones con variables del test isométrico, sin que se encuentren correlaciones con la marca en 100 metros lisos. La principal conclusión de nuestros datos es que las variables medidas en un test isométrico van a tener alta relación con la primera fase de la carrera en pruebas de velocidad.

    The mobile-bearing Salto total ankle prosthesis has been reported to have promising outcomes. However, clinical reports on this prosthesis are few, and most have been published by the inventors and disclosed consultants. We retrospectively reviewed 59 patients who received Salto prosthesis unilaterally. The average follow-up was 35.9 (range, 6-56) months. Clinical and radiologic results were evaluated. Clinical results were evaluated according to visual analog scale (VAS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, Ankle Osteoarthritis Scale (AOS) pain and disability score, and ankle range of motion (ROM) in dorsiflexion/plantarflexion. In the radiographic evaluation, we measured the tibial angle (TA), talar angle (TAL), tibial slope, and talocalcaneal angle (TCA) on weightbearing radiographs. By the last follow-up, 7 of 59 patients (11.9%) had undergone reoperation, and 3 of 59 implants (5.1%) had been removed. The prosthesis survival was 94.9% (95% CI, 89.1%-100%). With any reoperation as the endpoint of follow-up, the clinical success rate was 88.1% (95% CI, 79.4%-96.9%). The mean postoperative visual analog scale score, AOFAS ankle-hindfoot score, and Ankle Osteoarthritis Scale pain and disability score improved significantly ( P < .001). The ankle range of motion also improved from preoperative 33.4 ± 16.6 to 40.3 ± 15.5 postoperatively ( P < .001); however, there was no statistically significant change in plantarflexion ( P = .243). Radiolucent areas and osteolysis were found in 28 (47.5%) and 27 (45.8%) patients, respectively. Heterotopic ossification was observed in 13 patients (22.0%). In this series, early clinical and radiographic outcomes of this prosthesis were promising. We believe the early radiolucent lines were probably due to the gap at the implant and bone interface, and they disappeared at the time of osseous integration. However, longer follow-up is necessary to determine the long-term durability and survivorship

    Full Text Available Salto a la Gloria recounts the life of the eminent Spanish histologist Santiago Ramón y Cajal from his childhood in Petilla de Aragón (Navarra, Spain. until the awarding of the 1906 Nobel Prize in Physiology and Medicine. Without avoiding stereotypes (the mischievous child, the absentminded scientist dedicated exclusively to science and archetypes surrounding the scientist at that time, the film moulds a biography both entertaining and decidedly close to reality. It includes moral messages specific to the historical moment in which it was filmed, and humor scenes clever not only in content, but also in their placement throughout the film. The director utilizes well-implemented sharp contrasts in order to unite the events of Cajal’s life: his rural childhood, his participation in Cuba’s war of independence or his admission into Zaragoza’s School of Medicine (Spain. From a current mentality, and in light of the true knowledge of Cajal’s life, scenes that attempt to emphasize his greatness seem comical, like the cabaret scene where the only thing that remains for him to say is “sin, sin....” In short, a good movie considering the financial resources provided and the time in which it was filmed.

    Full Text Available This paper is the outcome of a survey on environmental impacts due to visitors in a tourist attraction, using geotechnology as a tool. The study was carried out at Salto Ventoso, Farroupilha, Rio Grande do Sul State (Brazil, a tourist attraction with major importance for the region. At the site, a private area, the attraction is a 60 meters (197 feet height cascade and its scenic landscape. Visitors can also hike through the trail that goes behind the waterfall. The trail was mapped using GPS (Global Positioning System and theodolite, and divided into twelve sections, which were evaluated on the issues of declivity, width, damage to natural resources and infrastructure, drainage problems, number of unofficial trails and amount of waste. The results showed that the site presents a series of environmental impacts resulting from both lack of planning and great amount of visitors. Some strategies for managing the site would be the installation of safety and signing infrastructure, as well as a work on environmental awareness of the visitors and their impacts on site.

De esta forma, podemos concluir que existen diferencias entre categorías, no solo en el valor de las variables, sino en la correlación de estas, por lo que las variables a controlar en el entrenamiento y a desarrollar podrían ser diferentes en función de dicha categoría.

  2. Salto de Miranda. Trabajos de excavación de la galería

    Full Text Available The first article of this series was published in issue N.° 162 of «Informes de la Construcción», under the title «Salto de Miranda». The present article deals with the work of excavating the gallery. Modern practice requires that to do this type of work successfully the auxiliary material should be most carefully studied beforehand. N.° 164 of the this magazine has included a paper entitled «Recent progress in the auxiliary material for underground gallery excavation», summarising the most recent type of machinery now available in the market. Since the Grand Coulee Dam was built by the Bureau of Reclamation, where essentially new techniques were introduced, including minimum times for maximum progress, these new procedures and equipment have been generally adopted throughout the world. To this must be added the urgent and increasing demands for electric power, and the vast amounts of money involved in these hydroelectric projects, which explain the rapid adoption of automatic procedures in this kind of work. In this paper the author explains how, using the means available to him, he sought to coordinate the various constructional tasks, to get as near as possible to the most economic working cycle. Underground ventilation is an acute problem, and involves the safety of those working inside the tunnel. The author explains, in simple terms, how the theory of fluids and air circulation can affect the rational and practical solution of providing adequate air supply for the health and comfort of the underground worker. To attain this end, however, a considerable mechanical and economic investment is necessary.En el número 163 de Informes de la Construcción se publicó el primer trabajo de esta serie, con el título de «Salto de Miranda».

Foram avaliados os constituintes do hemograma, a atividade sérica das enzimas CK, AST e LDH e a concentração TBARS na membrana de eritrócitos. A suplementação utilizada apresentou efeito sobre alguns parâmetros do hemograma, uma vez que no GT houve retorno aos níveis basais de número de hemácias e leucócitos, caracterizado por neutrofilia, em até seis horas. No GC, tais valores retornaram aos níveis de repouso entre 12 e 24 horas. Para a AST, o GT retornou ao valor do repouso seis horas após a realização do exercício. No entanto, não houve efeito sobre as enzimas CK e LDH, nem para o TBARS. Apesar de terem sido observadas diferenças na dinâmica de alguns parâmetros hematológicos entre os grupos, não foi possível determinar atividade antioxidante no GT no delineamento experimental utilizado, o que demonstra a necessidade de mais estudos para o entendimento do estresse oxidativo em cavalos atletas e a suplementação com antioxidantes na dieta desses animais.

    Full Text Available O artigo pretende avaliar criticamente o conceito de fé e o modo como a fé cristã é racionalmente justificada por Alvin Plantinga em sua principal obra Warranted Christian Belief (2000. Para tanto, o texto parte de uma comparação com a proposta de Richard Swinburne. Após discutir brevemente a epistemologia geral de Plantinga, o texto expõe a sua aplicação à crença em Deus e à fé cristã. A tese de Plantinga de que a fé não constitui um “salto no escuro” e que o seu componente não-teórico é semelhante ao amor erótico é comparada com a visão de Swinburne, segundo a qual a fé firme pode comportar elementos de incerteza na crença e supõe uma decisão voluntária, sendo, por isso mesmo, meritória. A comparação sugerirá que as diferenças indicam uma possibilidade de complementaridade entre as duas concepções

    1994-01-01

    The handspring 1 1/2 front salto vault in the tucked position is deemed to be an important high-level vault. It was the compulsory vault of the 1988 Olympics and is a building block for more advanced skills in the handspring family. The purpose of this study was to predict an individual's optimal performance of a handspring 1 1/2 front salto vault. An assessment of the athlete's present performance ability was determined using cinematographical analysis of three trials. These trials were judged as being typical high-level performances of the vault. Secondly, an objective function was identified based on the performance result of points awarded. The objective function was composed of those performance variables that, if maximized, would result in minimal deductions. Postflight height and distance were identified as those variables. Angular momentum was included in a penalty function form to ensure that sufficient angular momentum was present for successful completion of the skill. A Lagrangian approach was used to derive the equations of motion and a Rayleigh-Ritz procedure, using fifth-degree polynomials, was used to represent and discretize the state variables. The predicted optimal performance of the skill displayed greater virtuosity in postflight height, distance and angular momentum when compared to the individual's best trial performance. The results of this study generally fall within the limits observed for elite vaulters.

    The Salto Grande Reservoir is used for electric generation, irrigation, fish farming, recreation and water supply for the region's cities. The reservoir belongs to the city of Americana, located in on the eastern region of Sao Paulo State, Brazil. It belongs to the Piracicaba River Hydrographic Basin, the second most important economic and populated region and one of the most polluted areas in the State. This basin is located in a highly industrialized and agricultural region. Due to urban, industrial and agricultural activities as well as sewage wastes the water and sediments of this reservoir and surroundings are extremely contaminated, mainly by metals, according to CETESB (Environmental Control Agency of the Sao Paulo State). In order to obtain better information about its sediment contamination the present study reports results of the concentration of some major (Ca, Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Se, Ta, Th, U, Zn and rare earth (Ce, Eu, La, Lu, Nd, Sc, Sm, Tb and Yb)) elements in sediments and Cd, Cr, Cu, Ni and Pb concentration in sediments and water from the Salto Grande Reservoir. Multielementar analysis was carried out by Instrumental Neutron Activation Analysis (INAA). Multielemental concentrations in the sediment samples were compared to NASC (North American Shale Composite) values. The concentration values for metals As, Cd, Cr, Cu, Pb, Ni and Zn were compared to the Canadian Council of Minister of the Environment (CCME) oriented values (TEL and PEL) and adopted by CETESB, (author)

    Full Text Available O salto alto há muitos anos tem sido um grande aliado das mulheres, tornando-se uma ferramenta fundamental em seu dia a dia. Contudo, a utilização indiscriminada, seja do ponto de vista da frequência de utilização ou da altura do salto, pode trazer prejuízos para a saúde do corpo, que, a busca do melhor equilíbrio, pode desencadear alterações da postura, trazendo problemas para os pés e para a coluna vertebral. Os objetivos deste estudo foram: identificar a postura das curvaturas das colunas vertebral, torácica e lombar de estudantes universitárias, a partir do conhecimento dos ângulos destas curvaturas, e comparar esta postura nas situações com salto alto e com os pés descalços. Foram avaliadas 34 estudantes do sexo feminino, com idades médias de 20±1,9 anos, utilizando o instrumento arcômetro, nas situações com salto alto de 9 cm de altura e com pés descalços. O arcômetro foi colocado sobre os processos espinhosos das vértebras T1, T12, L1 e L5, identificados por palpação, e forneceu os ângulos das curvaturas. Para verificar as diferenças dos ângulos e da postura entre as duas situações de teste, foram utilizados o teste t pareado e o do χ², respectivamente (a=0,05. Os resultados demonstraram que a utilização de salto alto não modificou significativamente os ângulos das curvaturas torácica e lombar da coluna vertebral, bem como não interferiu na classificação da postura das estudantes universitárias, as quais, em sua maioria, apresentaram postura normal da coluna vertebral.For many years, high heels have been a great ally of women becoming an important tool in their everyday lives. However, its use, especially indiscriminate in the point of view of the use frequency or heel height, can bring harm to the body, which, in the search for better balance, may favor body posture changes by bringing injuries to the feet and to the spine. The aims of this study were: to identify the curvatures position of

    Full Text Available Este estudo teve como objetivo identificar as estratégias de dispersão de propágulos, a distribuição espacial e a estratificação vertical de espécies arbóreas em um fragmento de Floresta Ombrófila Mista em Lages, SC. Para amostragem da vegetação arbórea, foram alocadas 25 parcelas de 400 m² (20 m x 20 m e todos os indivíduos arbóreos dentro das parcelas com diâmetro a altura do peito (DAP, medido a 1,30 m do solo maior ou igual a 5 cm foram identificados e tiveram sua altura estimada. Para complementar a lista florística, foram feitos caminhamentos aleatórios no fragmento objetivando identificar espécies arbóreas não amostradas nas parcelas. As espécies foram classificadas segundo: i a sua síndrome de dispersão em zoocórica, anemocórica ou autocórica; ii o padrão de distribuição espacial dos indivíduos, considerando-se a distribuição aleatória, agregada e uniforme; iii a posição no estrato vertical da floresta, como sendo dos estratos superior, intermediário ou inferior. Do total de 87 espécies amostradas, 80,5% foram classificadas como zoocóricas, 16,1% como anemocóricas e 3,4% como autocóricas. Verificou-se a predominância de espécies com distribuição espacial aleatória e pertencente ao estrato superior, com altura superior ou igual a 12,45 m. Os resultados indicam a importância da fauna silvestre para a manutenção do funcionamento ecológico do fragmento estudado, uma vez que a maior parte das espécies são zoocóricas. O conhecimento desses atributos das populações arbóreas pode subsidiar estratégias de conservação e manejo de fragmentos florestais na região, uma vez que permite conhecer melhor a ecologia das espécies.

    Full Text Available We describe an efficient computational scheme for downward surface flux computations in a vertically inhomogeneous grey planetary atmosphere for different values of solar zenith angle. We start with the basic equations of a recently developed discrete ordinates spectral nodal method, and we derive suitable bidirectional functions whose diffuse components do not depend on the solar zenith angle. We then make use of these bidirectional functions to construct an efficient scheme for computing the downward surface fluxes in a given model atmosphere for a number of solar zenith angles. We illustrate the merit of the computational scheme described here with downward surface flux computations in a three-layer grey model atmosphere for four values of solar zenith angle, and we conclude this article with general remarks and directions for future work.Este artigo descreve um esquema computacional baseado em desenvolvimentos recentes do método espectro-nodal de ordenadas discretas para o cálculo eficiente do fluxo radiativo superficial em uma atmosfera planetária cinza e verticalmente não-homogênea para valores distintos do ângulo zenital solar. A partir das equações básicas do método espectro-nodal de ordenadas discretas, são obtidas funções bidirecionais discretas cujas componentes difusas não dependem do ângulo zenital solar. Com essas funções bidirecionais discretas, é construído um esquema computacional para calcular eficientemente fluxos radiativos superficiais em uma dada atmosfera-modelo para vários ângulos zenitais solares. O mérito computacional do esquema resultante é ilustrado com resultados numéricos para os fluxos radiativos superficiais em uma atmosfera-modelo cinza com três camadas para quatro valores distintos do ângulo zenital solar.

    The INMETRO/ANP 1 regulation (2000), presents rules to be followed for measuring and calibrating cylindrical vertical oil storage tanks in Brazil, according to ISO 7507-1 (1993) standard. A methodology for estimating the uncertainty (95,45 % confidence level) of the volume in a custody transfer process was developed, based on ISO GUM (1998) standard. The strapping method was selected for this study, because it has been used as a standard procedure by INMETRO. In this study, the same uncertainty values, as suggested by the standard, were used to estimate the uncertainty of the liquid volume in the tank. This study showed that the uncertainty of the transferred liquid volume from the tank varies from 0,2% to 0,4%, being smaller for larger volumes, which is thus the recommended application. The uncertainty of the ring height measurement is the largest contribution to the volume measurement uncertainty, and, thus, must be accurately measured. The tank internal diameter uncertainty is a small contribution to it. This paper calculates the uncertainty of liquid volume transferred from the tank by three methods, namely, this paper's, ISO 7507- 1's and INMETRO's, and shows that the most important contribution to the measurement uncertainty is the density measurement uncertainty, which must be accurately measured, at least, to within {+-} 0,0005, if the volume uncertainty is to remain in the 0,5 % to 1 % range.

    Full Text Available O cultivo do morangueiro fora do solo possibilita a eliminação do uso de produtos para desinfecção, reduzindo o consumo de frutos contaminados e a agressão ao meio ambiente, além de proporcionar melhor aproveitamento da área e maior facilidade de manejo da cultura. Este trabalho teve como objetivo avaliar, em ambiente protegido e colunas verticais, dois sistemas de irrigação: gotejamento por estacas (externo e autocompensante (interno; dois tipos de substratos: Horta 2 e Tabaco 1; com e sem drenagem. A cultivar utilizada foi a Oso Grande. O delineamento foi em blocos casualizados, com os tratamentos dispostos em parcela subsubdividida, com três repetições. Com base nos rendimentos obtidos nos terços superior, médio e inferior das colunas, o sistema de irrigação mais indicado é o gotejamento por estacas (externo, com drenagem na extremidade inferior da coluna. Os substratos não diferem quanto à produção, mas Horta 2 incrementa o teor de antocianina nos frutos.Since strawberry cultivation in soil less system does not needs disinfection products, it decreases fruits and environmental contamination. Besides it provides a better utilization of the area and makes easy the management of the culture. The objective of this work was to evaluate two irrigation systems: dripping for props (outside and self compensate (inside; and two types of substrates: Horta 2 and Tabaco 1; with or without draining, on the cultivar Oso Grande of strawberry. The experiment was carried out under protected cultivation and in vertical columns conditions. The experimental design was randomized blocks, with three replications, and the treatments were arranged in a split-plot. The strawberry yield found in the upper, medium, and lower positions of the columns indicates that the dripping for props (outside is the most efficient irrigation system, since drainage is used in the lower extremity of the column. Although there were no differences substrates, Horta

    Full Text Available PURPOSE: Sleeve gastrectomy (SG removes substantial part of the gastric mucosa, which produces ghrelin. This reduction is expected to force other organs, such as the duodenum, to compensate by increasing the number of ghrelin-producing cells. The purpose of this study was to evaluate whether this response occurs. METHODS: Twelve adult male, Wistar rats underwent SG and were reoperated 30 or 60 days after the initial surgery. During the second surgery, a segment of the duodenum was resected to count ghrelin cells using immunohistochemistry. In six animals, SG was not performed, and the duodenal segment served as a control for ghrelin cell counts. The ghrelin cell index (GCI, which is the number of ghrelin cells divided by the number of villi in each segment, was measured and used in statistical analysis by one-way analysis of variance (ANOVA. RESULTS:There were increases in the absolute numbers of cells 30 and 60 days after SG, but statistical analysis by ANOVA showed no significant difference between the groups. CONCLUSION: A compensatory increase in the number of duodenal immunopositive ghrelin cells did not occur as a response to sleeve gastrectomy.OBJETIVO: A gastrectomia vertical (GV remove a maior parte das células produtoras de grelina. Esta redução poderia induzir o duodeno a produzir mais células de grelina de forma compensadora. O objetivo deste trabalho foi estudar se esta compensação ocorre.

  9. Acquired vertical accommodative vergence.

    Klein-Scharff, Ulrike; Kommerell, Guntram; Lagrèze, Wolf A

    2008-03-08

    Vertical accommodative vergence is an unusual synkinesis in which vertical vergence is modulated together with accommodation. It results from a supranuclear miswiring of the network normally conveying accommodative convergence. So far, it is unknown whether this condition is congenital or acquired. We identified an otherwise healthy girl who gradually developed vertical accommodative vergence between five to 13 years of age. Change of accommodation by 3 diopters induced a vertical vergence of 10 degrees. This observation proves that the miswiring responsible for vertical accommodative vergence must not necessarily be congenital, but can be acquired. The cause and the mechanism leading to vertical accommodative vergence are yet unknown.

    Group A rotavirus (RVA) is the most important etiologic agent of infant acute gastroenteritis (AGE) worldwide. Detection and molecular characterization of RVA in Salto department, Northwestern region of Uruguay, was conducted on 175 clinical samples, being 153 stool and 22 vomit samples, collected from hospitalized children with AGE, between 0-15 years old, from two hospitals of Salto city during 2011 and 2012. RVA was detected and genotyped by seminested multiplex RT-PCR in order to determine G- and P-genotypes. Positive samples were sequenced and phylogenetic analyses were carried out in order to determine lineages and sub-lineages. RVA were detected in 64 (37%) of the samples and the G and P genotypes observed were: 6% G1P[8], 23% G2P[4]/G2P[X]/GXP[4], 23% G3P[8]/G3P[X], 14% G12P[8]/G12P[X], 16% GXP[8], 1,5% G12P[9], 3% G2P[4]/[8], and 16% non-typeable. VP7 and VP4 genotypes related to DS-1 like gene constellation were prevalent during 2011 and those VP7 and VP4 genotypes related to Wa-like constellation were prevalent during 2012 (mainly represented by G3P[8]). Interestingly, RVA was detected in vomit samples in a high prevalence (41%). RVA was observed mainly in the age group between 1 and 5 years old (75% of the cases), and seasonality with a high detection rate in winter season was observed for the two consecutive years of surveillance. To our knowledge, this study represents the first detection and molecular characterization of RVA in Salto department, Northwestern region of Uruguay; and the first identification of the emerging genotype G12 in the country. © 2015 Wiley Periodicals, Inc.

    Full Text Available Resumen: Los sistemas con conmutación de modos se definen como aquéllos que pueden exhibir diferente comportamiento dinámico en función del estado en que se encuentran. Pueden por tanto ser descritos por un conjunto finito de subsistemas dinámicos y una lógica que rige la conmutación entre ellos. Una alternativa para su control es la arquitectura multi-controlador con supervisión ya que permite utilizar controladores de modo diferentes y alcanzar así múltiples objetivos de control. Pero la conmutación de controladores suele tener como consecuencia la aparición de saltos o transitorios derivados que pueden ser inaceptables. Este tipo de sistemas y problemática son frecuentes en diferentes áreas de aplicación industrial, en donde la tecnología de control más utilizada es el Controlador Lógico Programable (PLC. Es por ello que el objetivo de este trabajo es presentar un método de diseño e implementación de un mecanismo de transferencia sin salto (BT en una arquitectura multi-modo y multi-bucle para sistemas con conmutación de modos, en PLC y en conformidad con el estándar IEC 61131-3. La estrategia BT se basa en que controladores de modos candidatos a conmutar realicen un seguimiento a los controladores activos, siendo la detección del estado de operación actual y de los posibles estados siguientes, clave en la definición de la forma de ejecución de los algoritmos de control que componen la arquitectura. Se presentan también los pasos del diseño de la arquitectura completa así como resultados experimentales que validan la arquitectura. Abstract: Switched mode systems are defined as those represented by a finite set of linear subsystems and a set of logic rules orchestrating the switching among them. A set of dynamic subsystems together with a logical system that orchestrates the switching among them could be used in order to describe it. An alternative to control them is a supervisory multi-mode controller architecture

    A vertical axis wind turbine is described. The wind turbine can include a top ring, a middle ring and a lower ring, wherein a plurality of vertical airfoils are disposed between the rings. For example, three vertical airfoils can be attached between the upper ring and the middle ring. In addition, three more vertical airfoils can be attached between the lower ring and the middle ring. When wind contacts the vertically arranged airfoils the rings begin to spin. By connecting the rings to a center pole which spins an alternator, electricity can be generated from wind.

  4. Longitudinal processes in Salto Grande reservoir (Americana, SP, Brazil and its influence in the formation of compartment system

    Directory of Open Access Journals (Sweden)

    L. H. ZANATA

    Full Text Available Studies on the longitudinal processes in reservoirs, involving physical, chemical and biological processes have been thoroughly appraised, suggesting the existence of a longitudinal organization controlled by the entrance and circulation of water which inserts modifications in the structuring of the system. To evaluate this effect, the Salto Grande reservoir (Americana, SP was analyzed in 11 sampling stations in its longitudinal axis, in the rainy and dry seasons of 1997 considering the physical chemical and biological variables. Analyzing the results in agreement with the declining concentration degree of the river--barrage direction, a more significant correlation was verified in the dry period for total phosphorus (r² = 0.86, dissolved total phosphate (r² = 0.83, nitrite (r² = 0.93, inorganic phosphate (r² = 0.89, ammonium (r² = 0.84 and suspended material (r² = 0.85. In the rainy period, only nitrite (r² = 0.90 and conductivity (r² = 0.89 presented correlation with the distance of the dam, which demonstrates the effects of precipitation and the operational mechanism of the dam, as well as the distinction among the physical (sedimentation, chemical (oxidation and biological (decomposition processes in spatial heterogeneity of the system. These factors were decisive in the organization of these communities, with higher occurrence of rotifers and copepods in relation to cladocerans, the first ones being more abundant in the entrance of the Atibaia river, decreasing towards the dam direction, while copepods presented an inverse pattern.

    Full Text Available Studies on the longitudinal processes in reservoirs, involving physical, chemical and biological processes have been thoroughly appraised, suggesting the existence of a longitudinal organization controlled by the entrance and circulation of water which inserts modifications in the structuring of the system. To evaluate this effect, the Salto Grande reservoir (Americana, SP was analyzed in 11 sampling stations in its longitudinal axis, in the rainy and dry seasons of 1997 considering the physical chemical and biological variables. Analyzing the results in agreement with the declining concentration degree of the river--barrage direction, a more significant correlation was verified in the dry period for total phosphorus (r² = 0.86, dissolved total phosphate (r² = 0.83, nitrite (r² = 0.93, inorganic phosphate (r² = 0.89, ammonium (r² = 0.84 and suspended material (r² = 0.85. In the rainy period, only nitrite (r² = 0.90 and conductivity (r² = 0.89 presented correlation with the distance of the dam, which demonstrates the effects of precipitation and the operational mechanism of the dam, as well as the distinction among the physical (sedimentation, chemical (oxidation and biological (decomposition processes in spatial heterogeneity of the system. These factors were decisive in the organization of these communities, with higher occurrence of rotifers and copepods in relation to cladocerans, the first ones being more abundant in the entrance of the Atibaia river, decreasing towards the dam direction, while copepods presented an inverse pattern. A distribution pattern similar to Copepoda was also verified for the Cladocera, evidencing a tendency to increase the density of organisms in the stations distant to the entrance of the Atibaia river, not being registered, however, a distribution gradient in the longitudinal axis, as observed for rotifers and copepods. In relation to the trophic degree a longitudinal gradient was also verified from

MÉTODOS: Foram selecionadas 36 adolescentes, 16 no grupo de não usuárias e 20 no grupo de usuárias, com idade entre 13 e 20 anos. A postura do pé foi analisada por fotos nas condições descalça e com calçado de salto alto tipo Anabella, previamente padronizado, após terem permanecido com ele por uma hora. Sua análise foi realizada pelo software SAPO. A impressão plantar foi realizada descalça e, a partir dela, calculado o Índice de Chipaux - Smirak para classificação do arco plantar. Para análise estatística, utilizou-se o teste t pareado para verificar igualdade entre lados direito e esquerdo. Foi realizado o teste de aderência Shapiro Wilk e, então, a análise inferencial por meio dos testes não paramétricos de Wilcoxon, o teste de Mann-Whitney e a correlação de Spearman. O nível de significância adotado foi de 0,05. RESULTADOS: Não foi encontrada correlação entre o tipo de arco plantar e a postura do pé das adolescentes estudadas. Porém, o ângulo do retropé se mostrou significativamente diferente, apresentando varo de retropé após a colocação do calçado em ambos os grupos, e o arco plantar do grupo de usuárias apresentou valores menores quanto ao Índice Chipaux - Smirak.

Atualmente, para aumentar a renda, o viticultor usa algumas alternativas tecnológicas que têm sido preconizadas, como o cultivo em manjedoura na forma de Y, em substituição ao sistema de condução em espaldeira; a poda extemporânea que permite duas safras por ano (de verão e de inverno e o uso de cobertura plástica para a proteção dos cachos contra intempéries e doenças. Portanto, foi desenvolvido um experimento visando a caracterizar a influência do sistema de condução, do uso de cobertura plástica e da poda extemporânea na produção e no tamanho dos cachos de 'Niagara Rosada'. Os resultados obtidos durante as safras de verão (2008 e 2009 e de inverno (2009 e 2010 permitiram verificar que, no sistema de condução em Y, foram obtidas maiores produções e tamanho de cacho em relação ao espaldeira. O uso de cobertura plástica no sistema em Y propiciou aumento de produção devido ao incremento em número e massa dos cachos. Também foi verificado que tanto a produção quanto a massa do cacho foram superiores na safra de verão em comparação à de inverno.The Niagara Rosada is the most important table grape cultivar for growers from Jundiaí region (São Paulo, Brazil.

    The objective of this paper is to summarize the goals, technical requirements, advantages, and potential risks of gastroplasty for treatment of severe obesity. Gastroplasty is preferred to more complex operations, as it preserves normal digestion and absorption and avoids complications that are peculiar to exclusion operations. The medical literature and a 30-year experience at the University of Iowa Hospitals and Clinics (UIHC) provides an overview of vertical banded gastroplasty (VBG) evolution. Preliminary 10-year results with the VBG technique currently used at UIHC are included. At UIHC the VBG is preferred to other gastroplasties because it provides weight control that extends for at least 10 years and the required objective, intraoperative quality control required for a low rate of reoperation. It is recommended that modifications of the operative technique not be attempted until a surgeon has had experience with the standardized operation--and then only under a carefully designed protocol. Realistic goals for surgery and criteria of success influence the choice of operation and the optimum, lifelong risk/benefit ratio. In conclusion, VBG is a safe, long-term effective operation for severe obesity with advantages over complex operations and more restrictive simple operations.

    Full Text Available CONTEXTUALIZAÇÃO: A fratura distal do fêmur é uma das possíveis complicações no período pós-operatório de reconstrução de LCA, porém, de incidência rara. RELATO DE CASO: Descreve-se o caso de um atleta de 34 anos, gênero masculino, no quinto mês de pós-operatório de reconstrução de LCA. O caso evoluía normalmente de acordo com o protocolo estabelecido; o paciente apresentava bom controle e estabilidade sensoriomotora, quando sofreu fratura supracondiliana do fêmur ao realizar um salto durante atendimento fisioterápico. A reconstrução ligamentar foi realizada com enxerto dos músculos flexores do joelho e a fratura, ocasionada posteriormente, reduzida e fixada com placa e parafuso. Dez meses após a redução aberta e fixação interna da fratura, apresenta função regular na escala Lysholm, amplitude de movimento normal e força muscular grau V em flexores e extensores da coxa. DISCUSSÃO: Poucos relatos de caso semelhantes ao presente foram encontrados na literatura; a maioria apresentou fratura do fêmur após a reconstrução do LCA com tendão patelar. Este caso mostra-se relevante pela associação da fratura supracondiliana do fêmur com reconstrução ligamentar com tendões dos flexores, visto que apenas um trabalho seguiu tal direção. Dentre as prováveis causas dessa fratura, destacam-se uma fragilidade óssea por desuso e túnel ósseo femoral de diâmetro maior que o padrão, apesar de não haver consenso em relação a essas alterações. Uma hipótese sugerida pelos autores deste relato é de que o túnel ósseo de fixação do enxerto pode ter sido um intensificador de estresse sobre o local da fratura.BACKGROUND: Distal femoral fracture is one of the possible complications on the post operative period of the ACL reconstruction; however, with rare incidence.

Porém, não é raro que, quando se avaliam medidas isoladamente, tenha-se uma idéia errônea do que a face do paciente apresenta em termos de padrão vertical. OBJETIVOS: o presente trabalho realizou diferentes correlações entre a ângulo do plano mandibular (GoGn-SN, o índice de altura facial (IAF e a sobremordida, avaliando a resposta dessas correlações quanto ao padrão citado na literatura, além de identificar possíveis fatores que, eventualmente, levassem essas medidas a um comportamento fora desse padrão. METODOLOGIA: o estudo foi realizado em radiografias cefalométricas de perfil entre dois grupos de indivíduos brasileiros - um portador de oclusão excelente e outro de má oclusão - atendidos no Curso de Especialização em Ortodontia e Ortopedia Facial da Faculdade de Odontologia da Universidade Federal da Bahia. RESULTADOS: as medidas esqueléticas GoGn-SN e IAF apresentaram forte correlação entre si. A sobremordida, entretanto, não apresentou correlação com essas medidas no grupo com oclusão excelente e demonstrou fraca correlação naquele com má oclusão. Uma correlação coerente com o padrão citado na literatura foi encontrada em 35% e 31% dos indivíduos dos grupos com oclusão excelente e má oclusão, respectivamente. Os indivíduos restantes apresentaram variações na altura dentoalveolar dos incisivos, compensando as displasias verticais. No grupo com oclusão excelente, esse fator se somou às compensações na região de molares. CONCLUSÕES: os resultados encontrados indicam que a maior parte dos grupos apresentou um comportamento diferente do padrão citado na literatura, quando as três medidas foram correlacionadas simultaneamente.INTRODUCTION: The evaluation of facial vertical proportions is one of the most important features

    Full Text Available En este trabajo se evaluó objetivamente la relación entre la variabilidad del rendimiento de la pastura en el departamento de Salto (Uruguay y la variabilidad climática. Se analizaron también las posibles implicancias del cambio climático futuro. Se utilizaron datos diarios y mensuales de la estación meteorológica Salto en el período 1961-1990 y un registro de datos experimentales de crecimiento de pastura en el período 1980-1994. Adicionalmente, se emplearon salidas diarias de reanálisis del NCEP y de los Modelos de Circulación General HadCM3 y CSIRO-Mk2 para los escenarios A2 y B2. Las correlaciones simples entre las variables climáticas y la pastura confirmaron en términos cuantitativos la sensibilidad de la pastura a la variabilidad climática, explicando entre el 20% y 58% de la varianza en los rendimientos. Las mayores asociaciones se encontraron en otoño (principalmente con las variables relacionadas con la precipitación y verano. En invierno no se observaron asociaciones significativas. El efecto conjunto de las variables climáticas explicó entre el 36% y 86% de la variabilidad en el crecimiento de la pastura. Para los escenarios estudiados, los incrementos proyectados en las temperaturas mínima y máxima permitirían reducir las probabilidades de ocurrencia de temperaturas por debajo del umbral mínimo considerado para la pastura (10ºC y aumentar las probabilidades de estrés térmico durante el verano. La precipitación presentaría incrementos que podrían aumentar la incidencia de excedentes hídricos en invierno. Los incrementos proyectados para el verano no compensarían los aumentos de la demanda hídrica atmosférica por mayores temperaturas.This work aimed to evaluate the relationship between natural pasture yield and climate variability in the district of Salto (Uruguay, and to analyze the possible implications of future climate change.

    Full Text Available This study aims to analyze the diet and trophic ecomorphology of Odontesthes bonariensis, relating these features with species' abundance in the natural environment and in the Salto Caxias reservoir (at Iguaçu river after the reservoir's formation. The samples were carried out before (from March 1997 to February 1998- pre and after (from October 1998 to February 2001 - post 1 and 2 the damming. The stomach contents of 218 individuals were analyzed by occurrence and volumetric methods. O. bonariensis' diet is based on insects, scales, plants and detritus. Microcrustaceans (Cladocera and Copepoda were the main items, allowing the characterization of the species as zooplanktivore. The species has a superior position and protractible mouth, with small teeth, creating a serrated pattern, uniformly lined side by side. There are many gill rakers, that are long and close together (typical of filtering fishes; the stomach is ill defined and the intestine is short. There was a gradual increase of O. bonariensis' abundance during the period of field study, mainly after the second year of damming. This fact seems to be closely related with the high abundance and availability of zooplankton in the dammed environment, and also with the ability of the species to exploit this resource.

    Rheology of emulsion mixtures and void fraction measurements of multiphase flows requires proper instrumentation. Sometimes it is not possible to install this instrumentation inside the pipe or view the flow. Ultrasound technology has characteristics compatible with the requirements of the oil industry. It can assist the production of heavy oil. This study provides important information for an analysis of the feasibility of developing non-intrusive equipment. These probes can be used for measurement of multiphase void fraction and detect the flow pattern using ultrasound. Experiments using simulated upward air-water vertical two-phase flow show that there is a correlation between the acoustic attenuation and the concentration of the gas phase. Experimental data were obtained through the prototype developed for ultrasonic data acquisition. This information was processed and used as input parameters for a neural network classifier. Void fractions ({proportional_to}) were analyzed between 0% - 16%, in increments of 1%. The maximum error of the neural network for the classification of the flow pattern was 6%. (author)

    This study investigated the influence of a 4-wk combined electromyostimulation (EMS) and plyometric training program on the vertical jump performance of 10 volleyball players. Training sessions were carried out three times weekly. Each session consisted of three main parts: EMS of the knee extensor muscles (48 contractions), EMS of the plantar flexor muscles (30 contractions), and 50 plyometric jumps. Subjects were tested before (week 0), during (week 2), and after the training program (week 4), as well as once more after 2 wk of normal volleyball training (week 6). Different vertical jumps were carried out, as well as maximal voluntary contraction (MVC) of the knee extensor and plantar flexor muscles. At week 2, MVC significantly increased (+20% knee extensors, +13% plantar flexors) as compared to baseline ( vertical jumps considered were also significantly higher compared to pretraining ( jump) and 21% (squat jump). The significant increases in maximal strength and explosive strength produced by the present training program were subsequently maintained after an additional 2 wk of volleyball training. EMS combined with plyometric training has proven useful for the improvement of vertical jump ability in volleyball players. This combined training modality produced rapid increases (approximately 2 wk) of the knee extensors and plantar flexors maximal strength. These adaptations were then followed by an improvement in general and specific jumping ability, likely to affect performance on the court. In conclusion, when EMS resistance training is proposed for vertical jump development, specific work out (e.g., plyometric) must complement EMS sessions to obtain beneficial effects.

    Full Text Available BACKGROUND: Surgical options for morbid obesity are diverse, and the Roux-en-Y gastric bypass, initially described by Fobi has gained popularity. Knowledge about the physiology of the bypassed stomach is limited because this newly produced segment of the stomach is inaccessible to endoscopic or contrast radiological studies. AIM: To evaluate the myoelectric activity of the bypassed stomach and its reply to the feeding. METHODS: An experimental protocol was conducted to evaluate postoperative gastric bypassed motility in dogs submitted to the Roux-en-Y gastric bypass procedure. Two groups of five animals were studied on postoperative fasting and after a standard meal, recording electrical response and control activity. Both control and Roux-en-Y gastric bypass operated study group had a pair of electrodes placed on three points of the remaining stomach: fundus, body and antrum. Data registration was performed after complete ileus resolution, and analysed with DATA Q Inst. series 200. RESULTS: The results achieved on the conditions of this study suggest that: 1. the remaining stomach maintain the same pattern of motility; 2. there is a reduced fasting electromyography activity following the Roux-en-Y gastric bypass procedure; 3. significantly reduced fasting electric control activity when compared both groups, and a markedly reduced fasting response electric activity and; 4. the electric response to the feeding kept the same standard of the stomach, however in a statistically reduced way. CONCLUSION: The electrical activity of the bypassed stomach of Roux-en-Y gastric bypass procedure kept the same pattern but in a statistically reduced number of contraction.RACIONAL: Dentre a grande diversidade de opções cirúrgicas para obesidade mórbida, a gastroplastia vertical com reconstituição em Y-de-Roux, tornou-se extremamente popular.

  9. Vertical allometry: fact or fiction?

    Science.gov (United States)

    Mahmood, Iftekhar; Boxenbaum, Harold

    2014-04-01

    In pharmacokinetics, vertical allometry is referred to the clearance of a drug when the predicted human clearance is substantially higher than the observed human clearance. Vertical allometry was initially reported for diazepam based on a 33-fold higher human predicted clearance than the observed human clearance. In recent years, it has been found that many other drugs besides diazepam, can be classified as drugs which exhibit vertical allometry. Over the years, many questions regarding vertical allometry have been raised. For example, (1) How to define and identify the vertical allometry? (2) How much difference should be between predicted and observed human clearance values before a drug could be declared 'a drug which follows vertical allometry'? (3) If somehow one can identify vertical allometry from animal data, how this information can be used for reasonably accurate prediction of clearance in humans? This report attempts to answer the aforementioned questions. The concept of vertical allometry at this time remains complex and obscure but with more extensive works one can have better understanding of 'vertical allometry'. Published by Elsevier Inc.

    A vertical axis wind turbine airfoil is described. The wind turbine airfoil can include a leading edge, a trailing edge, an upper curved surface, a lower curved surface, and a centerline running between the upper surface and the lower surface and from the leading edge to the trailing edge. The airfoil can be configured so that the distance between the centerline and the upper surface is the same as the distance between the centerline and the lower surface at all points along the length of the airfoil. A plurality of such airfoils can be included in a vertical axis wind turbine. These airfoils can be vertically disposed and can rotate about a vertical axis.

    Vertical saccades have never been studied in dyslexic children. We examined vertical visually guided saccades in fifty-six dyslexic children (mean age: 10.5±2.56 years old) and fifty-six age matched non dyslexic children (mean age: 10.3±1.74 years old). Binocular eye movements were recorded using an infrared video-oculography system (mobileEBT®, e(ye)BRAIN). Dyslexic children showed significantly longer latency than the non dyslexic group, also the occurrence of anticipatory and express saccades was more important in dyslexic than in non dyslexic children. The gain and the mean velocity values were significantly smaller in dyslexic than in non dyslexic children. Finally, the up-down asymmetry reported in normal population for the gain and the velocity of vertical saccades was observed in dyslexic children and interestingly, dyslexic children also reported an up-down asymmetry for the mean latency. Taken together all these findings suggested impairment in cortical areas responsible of vertical saccades performance and also at peripheral level of the extra-ocular oblique muscles; moreover, a visuo-attentionnal bias could explain the up-down asymmetry reported for the vertical saccade triggering.

    2013-04-01

    Longuet-Higgins and Stewart (J Fluid Mech 13:481-504, 1962; Deep-Sea Res 11:529-562, 1964) and later Phillips (1977) introduced the problem of waves incident on a beach, from deep to shallow water. From the wave energy equation and the vertically integrated continuity equation, they inferred velocities to be Stokes drift plus a return current so that the vertical integral of the combined velocities was nil. As a consequence, it can be shown that velocities of the order of Stokes drift rendered the advective term in the momentum equation negligible resulting in a simple balance between the horizontal gradients of the vertically integrated elevation and wave radiation stress terms; the latter was first derived by Longuet-Higgins and Stewart. Mellor (J Phys Oceanogr 33:1978-1989, 2003a), noting that vertically integrated continuity and momentum equations were not able to deal with three-dimensional numerical or analytical ocean models, derived a vertically dependent theory of wave-circulation interaction. It has since been partially revised and the revisions are reviewed here. The theory is comprised of the conventional, three-dimensional, continuity and momentum equations plus a vertically distributed, wave radiation stress term. When applied to the problem of waves incident on a beach with essentially zero turbulence momentum mixing, velocities are very large and the simple balance between elevation and radiation stress gradients no longer prevails. However, when turbulence mixing is reinstated, the vertically dependent radiation stresses produce vertical velocity gradients which then produce turbulent mixing; as a consequence, velocities are reduced, but are still larger by an order of magnitude compared to Stokes drift. Nevertheless, the velocity reduction is sufficient so that elevation set-down obtained from a balance between elevation gradient and radiation stress gradients is nearly coincident with that obtained by the aforementioned papers.

  7. Multiservice Vertical Handoff Decision Algorithms

    2006-01-01

    Full Text Available Future wireless networks must be able to coordinate services within a diverse-network environment. One of the challenging problems for coordination is vertical handoff, which is the decision for a mobile node to handoff between different types of networks. While traditional handoff is based on received signal strength comparisons, vertical handoff must evaluate additional factors, such as monetary cost, offered services, network conditions, and user preferences. In this paper, several optimizations are proposed for the execution of vertical handoff decision algorithms, with the goal of maximizing the quality of service experienced by each user. First, the concept of policy-based handoffs is discussed. Then, a multiservice vertical handoff decision algorithm (MUSE-VDA and cost function are introduced to judge target networks based on a variety of user- and network-valued metrics. Finally, a performance analysis demonstrates that significant gains in the ability to satisfy user requests for multiple simultaneous services and a more efficient use of resources can be achieved from the MUSE-VDA optimizations.

A análise estatística dos dados foi efetuada por meio de regressões múltiplas das variáveis, erro horizontal e erro vertical, em função das variáveis independentes: altitude; altitude e declividade. Os erros médios horizontais e verticais pouco dependem da altitude, bem como da altitude e declividade, induzindo à conclusão de que não há necessidade de se levar em conta compartimentos de relevo com declividades uniformes e constantes para o traçado das curvas de nível em aerofotos.This study was conducted to obtain level curves from vertical aerial photographs, using linear graphics correction in areas with different slope classes. Statistical analysis of data was made by multiple regressions of horizontal and vertical deviation as a function of the following independent variables: altitude, altitude and slope. Vertical and horizontal deviations showed no significant dependence either on altitude or the altitude and slope, leading to the conclusion that there is no need to involve topography with uniform and constant slopes to obtain iso-level curves from aerophotos.

    2007-05-01

    The eg3 experiment at the Jefferson Lab CLAS detector aims to determine the existence of the $\\Xi_{5}$ pentaquarks and investigate the excited $\\Xi$ states. Specifically, the exotic $\\Xi_{5}^{--}$ pentaquark will be sought by first reconstructing the $\\Xi^{-}$ particle through its weak decays, $\\Xi^{-}\\to\\pi^{-}\\Lambda$ and $\\Lambda\\to\\pi^{-}$. A kinematic fitting routine was developed to reconstruct the detached vertices of these decays, where confidence level cuts on the fits are used to remove background events. Prior to fitting these decays, the exclusive reaction $\\gamma D\\rightarrow pp\\pi^{-}$ was studied in order to correct the track measurements and covariance matrices of the charged particles. The $\\Lambda\\rightarrow p\\pi^{-}$ and $\\Xi^{-}\\to\\pi^{-}\\Lambda$ decays were then investigated to demonstrate that the kinematic fitting routine reconstructs the decaying particles and their detached vertices correctly.

    In this study we show the vertical distribution of atmospheric methane (CH4) measured in Sodankylä, Northern Finland. The CH4 profiles are retrieved from the direct Sun FTS measurements using the dimension reduction retrieval method. In the retrieval method, we have a few degrees of freedom about the profile shape. The data set covers years 2010-2016 (from February to November) and altitudes 0-40 km. The retrieved FTS profiles are validated against ACE satellite measurements and AirCore balloon measurements. The total columns derived from the FTS profiles are compared to the official TCCON XCH4 data. A vertically resolved methane data set can be used, e.g., to study stratospheric methane during the polar vortex.

    Full Text Available During the last decades, market segmentation and intra-industry trade have become increasingly relevant. The underlying hypothesis of our work is that distinct articles have heterogeneous potential for vertical differentiation, implying that different patterns of international specialization should be identifiable. We carry out an analysis on revealed comparative advantage (through the Lafay Index in specific sectors of interest. Then we highlight the emergence of diverse degrees of product quality differentiation among sectors (through the Relative Quality Index. Results confirm our hypothesis. Indeed it appears that only certain goods, for which the pace of either creative or technological innovation (or both is particularly fast, present a high degree of vertical differentiation and market segmentation. This allows countries to specialize in a particular product variety and gain market power position for that variety. These findings should be taken in due consideration when designing trade policies.

    An appropriate management of HBV infection is the best strategy to finally reduce the total burden of HBV infection. Mother-to-child transmission (MTCT) is responsible for more than one third of chronic HBV infections worldwide. Because HBV infection in infancy or early childhood often leads to chronic infection, appropriate prophylaxis and management of HBV in pregnancy is crucial to prevent MTCT. The prevention of HBV vertical transmission is a complex task and includes: universal HBV screening of pregnant women, administration of antivirals in the third trimester of pregnancy in women with high viral load and passive-active HBV immunoprophylaxis with hepatitis B vaccine and hepatitis B immune globulin in newborns of all HBV infected women. Universal screening of pregnant women for HBV infection, early identification of HBV DNA level in HBV-infected mothers, maternal treatment with class B according to FDA antivirals and passive/active anti-HBV immunoprophylaxis to newborns of HBV-positive mothers are crucial strategies for reducing vertical HBV transmission rates. Consideration of caesarean section in order to reduce the risk of vertical HBV transmission should be recommend in HBV infected pregnant women with high viral load despite antiviral therapy or when the therapy in the third trimester of pregnancy is not available.

    We present the first attempt to extract vertical stroke V{sub cb} vertical stroke from the Λ{sub b} → Λ{sub c}{sup +}l anti ν{sub l} decay without relying on vertical stroke V{sub ub} vertical stroke inputs from the B meson decays. Meanwhile, the hadronic Λ{sub b} → Λ{sub c}M{sub (c)} decays with M = (π{sup -},K{sup -}) and M{sub c} =(D{sup -},D{sup -}{sub s}) measured with high precisions are involved in the extraction. Explicitly, we find that vertical stroke V{sub cb} vertical stroke =(44.6 ± 3.2) x 10{sup -3}, agreeing with the value of (42.11 ± 0.74) x 10{sup -3} from the inclusive B → X{sub c}l anti ν{sub l} decays. Furthermore, based on the most recent ratio of vertical stroke V{sub ub} vertical stroke / vertical stroke V{sub cb} vertical stroke from the exclusive modes, we obtain vertical stroke V{sub ub} vertical stroke = (4.3 ± 0.4) x 10{sup -3}, which is close to the value of (4.49 ± 0.24) x 10{sup -3} from the inclusive B → X{sub u}l anti ν{sub l} decays. We conclude that our determinations of vertical stroke V{sub cb} vertical stroke and vertical stroke V{sub ub} vertical stroke favor the corresponding inclusive extractions in the B decays. (orig.)

Se utilizaron 24 ejemplares de las razas Silla Argentina, PSI y mestizo de la Escuela de Equitación del Ejército Nacional de Colombia, que participaron en pruebas de salto (1,10 – 1,20 m en diferentes centros ecuestres de la Sabana de Bogotá. Se determinó frecuencia cardiaca, frecuencia respiratoria y enzimas musculares (creatinquinasa (CK, lactato deshidrogenasa (LDH y el ácido láctico.. Se tomaron tres muestras: reposo, inmediatamente después del ejercicio y a las 6 horas posejercicio. Para la frecuencia cardiaca se utilizó un monitor POLAR S625; la frecuencia respiratoria se determinó mediante fonendoscopio; y las enzimas y el ácido láctico se analizaron en laboratorio. Se utilizó el método estadístico ANAVA para enzimas musculares y acido láctico y estadística descriptiva para frecuencia cardiaca y respiratoria. En los resultados se encontró un comportamiento estadísticamente significativo (p < 0.05 del ácido láctico y la enzima creatinkinasa, a diferencia del comportamiento de la enzima lactato deshidrogenasa, que fue no significativo. Las frecuencias cardiaca y respiratoria se elevaron de manera significativa posejercicio y regresaron a lo normal alrededor de las 6 seis horas. El ácido láctico se incrementó posejercicio y disminuyó a las 6 horas, contrario a lo reportado por otros autores. Se concluye que una vez analizadas estas variables, hay diferencias con los valores obtenidos por otros autores, que pueden deberse a la altitud, al tipo y tiempo de ejercicio realizado. Por tanto es indispensable continuar haciendo estudios en este campo.

  3. ?Vertical Sextants give Good Sights?

    Science.gov (United States)

    Richey, Michael

    Mark Dixon suggests (Forum, Vol. 50, 137) that nobody thus far has attempted to quantify the errors from tilt that arise while observing with the marine sextant. The issue in fact, with the related problem of what exactly is the axis about which the sextant is rotated whilst being (to define the vertical), was the subject of a lively controversy in the first two volumes of this Journal some fifty years ago. Since the consensus of opinion seems to have been that the maximum error does not necessarily occur at 45 degrees, whereas Dixon's table suggests that it does, some reiteration of the arguments may be in order.

    Full Text Available Background/Aim. Elevation in adduction is the most common pattern of vertical strabismus, and it is mostly treated with surgery. The results of weaking of inferior oblique muscle are very changeable. The aim of this study was to evaluate binocular vision using sensory tests before and one and six months after the surgery. Methods. A total of 79 children were divided in two groups: the first, with inferior oblique muscle of overaction (n = 52, and the second with dissociated vertical deviation (DVD, and primary inferior oblique muscle overaction (n = 27. We tested them by polaroid mirror test (PMT, Worth test at distance and near, fusion amplitudes on sinoptofore, Lang I stereo test and Wirt-Titmus stereo test. We examined our patients before and two times after the surgery for vertical strabismus. Results. Foveal suppression in the group I was found in 60.5% of the patients before, and in 56.4% after the surgery. In group II Foveal suppression was detected in 64.7% of the patients before, but in 55.6% 6 months after the surgery with PMT. Worth test revealed suppression in 23.5% of the patients before, and in 40.7% after the vertical muscle surgery. Parafoveal fussion persisted in about 1/3 of the patients before the surgery, and their amplitudes were a little larger after the surgery in the group I patients. Lang I stereo test was negative in 53.9% before and 51.9% after the surgery in the group I, and in 48.2% of the patients before and after the surgery in the group II patients. Wirt-Titmus stereo test was negative in 74.5% of the patients before and in 72.9% after the surgery in the group I, but in the group II it was negative in 70.8% before and in 68.0% of the patients 6 months after the surgery. Conclusion. Binocular responses were found after surgery in 65.7% of the patients the group I and in 55.6% patients the group II. There was no significant difference between these two groups, but binocular responses were more often in the patients

    ão existe nenhuma avaliação desta forma de transmissão, no entanto, sabe-se que em Salvador-Bahia 0, 7% a 0, 9% das gestantes de classe socio-econômica baixa são portadoras deste virus. Além disto, em Salvador, já foram detectados vários casos de linfoma/leucemia de células T do adulto e quatro casos de dermatite infectiva, condições que são diretamente ligadas à transmissão vertical do HTLV-I, demonstrando assim a importância desta via de transmissão entre nós. Através de seleção sorológica de gestantes no prenatal e evitando a amamentação nas soropositivas, conseguiu-se no Japão redução de ~ 80% da transmissão vertical deste virus. É necessário que no Brasil os órgãos de Saúde Pública comecem a fazer estudos no sentido de se certificar da magnitude deste problema. Sugerimos que em nosso país seja feita avaliação sorológica pré-natal em grupos selecionados, tais como: gestantes provenientes de áreas endêmicas, imigrantes japonesas ou descendentes de japoneses, usuárias de drogas injetáveis (UDI ou gestantes cujos parceiros sejam UDI, portadoras do virus da imunodeficiência adquirida, gestantes com comportamento sexual promíscuo e aquelas que tenham recebido transfusão sanguínea.

    Paper-based electronic devices are attracting considerable attention, because the paper platform has unique attributes such as flexibility and eco-friendliness. Here we report on what is claimed to be the firstly fully integrated vertically-stacked nanocellulose-based tactile sensor, which is capable of simultaneously sensing temperature and pressure. The pressure and temperature sensors are operated using different principles and are stacked vertically, thereby minimizing the interference effect. For the pressure sensor, which utilizes the piezoresistance principle under pressure, the conducting electrode was inkjet printed on the TEMPO-oxidized-nanocellulose patterned with micro-sized pyramids, and the counter electrode was placed on the nanocellulose film. The pressure sensor has a high sensitivity over a wide range (500 Pa-3 kPa) and a high durability of 10(4) loading/unloading cycles. The temperature sensor combines various materials such as poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), silver nanoparticles (AgNPs) and carbon nanotubes (CNTs) to form a thermocouple on the upper nanocellulose layer. The thermoelectric-based temperature sensors generate a thermoelectric voltage output of 1.7 mV for a temperature difference of 125 K. Our 5 × 5 tactile sensor arrays show a fast response, negligible interference, and durable sensing performance.

OBJETIVO: Determinar a relação entre três testes funcionais de equilíbrio com as principais medidas da plataforma de força em atletas. MÉTODO: Quinze atletas do sexo feminino praticantes de futebol de salão (futsal e handebol, com idades entre 13 a 17 anos participaram do estudo. As atletas realizaram três testes funcionais: 1 Star excursion balance test, 2 Salto lateral e 3 Figura em oito; além de um teste em apoio unipodal sobre uma plataforma de força com os olhos abertos durante 30 segundos. Os parâmetros do centro de pressão dos pés (COP foram calculados por análise estabilográfica. Para todos os testes (funcionais e plataforma, três tentativas foram realizadas e a média foi retida para as análises. RESULTADOS: As correlações entre os testes funcionais e a plataforma de força foram de r = 0,01 a -0,69 (fraca a moderada, dependendo da variável do COP. As melhores correlações (r = -0,69 foram encontradas entre o Star Excursion Balance Test de alcance e a área do COP, indicando que quanto maior a distância alcançada, melhor o equilíbrio. Segundo, uma correlação de fraca a moderada foi encontrada entre o teste da figura em oito e a área do COP (p. ex: r = 0.43. O teste de salto lateral não apresentou boa correlação com os obtidos na plataforma de força. CONCLUSÃO: Este estudo demonstrou que para a avaliação do equilíbrio em atletas de futsal e handebol feminino o teste Star Excursion Balance Test pode ser usados na ausência da plataforma de força para identificação de possíveis déficits de equilíbrio.

    Full Text Available The maximum volume of liquid bridge left between two vertically mounted spherical particles has been theoretically determined and experimentally measured. As the gravitational effect has not been neglected in the theoretical model, the liquid interface profile is nonsymmetrical around the X-axis. Symmetry in the interface profile only occurs when either the particle size ratio or the gravitational force becomes zero. In this paper, some equations are derived as a function of the spheres' sizes, gap width, liquid density, surface tension and body force (gravity/centrifugal to estimate the maximum amount of liquid that can be held between the two solid spheres. Then a comparison is made between the result based on these equations and several experimental results.

  12. Vertical jump coordination: fatigue effects.

    Rodacki, André Luiz Felix; Fowler, Neil E; Bennett, Simon J

    2002-01-01

    The aim of this study was to investigate the segmental coordination of vertical jumps under fatigue of the knee extensor and flexor muscles. Eleven healthy and active subjects performed maximal vertical jumps with and without fatigue, which was imposed by requesting the subjects to extend/flex their knees continuously in a weight machine, until they could not lift a load corresponding to approximately 50% of their body weight. Knee extensor and flexor isokinetic peak torques were also measured before and after fatigue. Video, ground reaction forces, and electromyographic data were collected simultaneously and used to provide several variables of the jumps. Fatiguing the knee flexor muscles did not reduce the height of the jumps or induce changes in the kinematic, kinetic, and electromyographic profiles. Knee extensor fatigue caused the subjects to adjust several variables of the movement, in which the peak joint angular velocity, peak joint net moment, and power around the knee were reduced and occurred earlier in comparison with the nonfatigued jumps. The electromyographic data analyses indicated that the countermovement jumps were performed similarly, i.e., a single strategy was used, irrespective of which muscle group (extensor or flexors) or the changes imposed on the muscle force-generating characteristics (fatigue or nonfatigue). The subjects executed the movements as if they scaled a robust template motor program, which guided the movement execution in all jump conditions. It was speculated that training programs designed to improve jump height performance should avoid severe fatigue levels, which may cause the subjects to learn and adopt a nonoptimal and nonspecific coordination solution. It was suggested that the neural input used in the fatigued condition did not constitute an optimal solution and may have played a role in decreasing maximal jump height achievement.

The predicted amino acid sequences of <em>CYP83A1-1em>, <em>CYP83A1-2 em>and <em>CYP83B1em> shared high sequence identity of 87.65, 86.48 and 95.59% to the corresponding ones in <em>Arabidopsis>, and 98.80, 98.61 and 98.80% to the corresponding ones in <em>Brassica pekinensis em>(Chinese cabbage, respectively. Quantitative real-time PCR analysis indicated that both <em>CYP83A1em> and <em>CYP83B1em> expressed in roots, leaves and petioles of pak choi, while the transcript abundances of <em>CYP83A1 em>were higher in leaves than in petioles and roots, whereas <em>CYP83B1 em>showed higher abundances in roots. The expression levels of glucosinolate biosynthetic genes were consistent with the glucosinolate profile accumulation in shoots of seven cultivars and three organs. The isolation and characterization of the glucosinolate synthesis genes in pak choi would promote the way for further development of agronomic traits via genetic engineering.

    Full Text Available Este estudo objectivou analisar as magnitudes dos impactos nos membros inferiores de atletas de andebol durante a recepção ao solo no remate em suspensão e relacioná-las com massa corporal (MC dos atletas, altura do salto (AS e ângulos de flexão do joelho (AJ e do quadril (AQ na recepção. Participaram nove atletas de andebol com idade de 22.2 ± 1.4 anos. Foi utilizado um acelerómetro triaxial para análise dos impactos no joelho e no tornozelo e um sistema de reconstrução tridimensional de movimento para análise cinemática do AQ, AJ e AS. Utilizou-se estatística descritiva, análise de variância e regressão linear múltipla, com significância de 5%. As maiores magnitudes de impactos ocorreram no eixo antero-posterior, tanto no joelho (28.24 g, quanto no tornozelo (59.81 g; 71% do impacto no joelho pode ser explicado pelas variáveis AQ e MC; 45% do impacto no tornozelo pode ser explicado pelas variáveis AQ e AJ. Conclui-se que o ângulo de flexão do quadril foi a variável mais determinante nos valores de impactos nos membros inferiores, enquanto a altura do salto parece não ter influência, mostrando que o domínio da técnica correcta de recepção ao solo pode minimizar as sobrecargas aplicadas no organismo dos atletas.

Se registró la fuerza vertical de cincuenta saltos realizados por diez deportistas de sexo masculino antes y después de un protocolo de fatiga. Se obtuvieron registros de electromiografía de superficie para seis músculos de miembro inferior y se analizó el nivel de activación y coordinación intermuscular. Para los análisis se consideraron por separado los tiempos de trabajo mecánico negativo y positivo. En ambas condiciones el curso temporal de distribución de fuerza es más importante para la performance que cualquier parámetro instantáneo. El tiempo de trabajo externo negativo fue significativamente menor en condición de fatiga. Los análisis electromiográficos mostraron un aumento en el nivel de activación de todos los músculos estudiados e importantes cambios en la secuencia de activación. Las variables cinético-temporales puntuales no resultaron buenos predictores de la altura del salto. Cuando el CMJ es ejecutado sin fatiga, un alto valor de estado activo favorece el trabajo positivo. Durante la fatiga, una compensación parcial del rendimiento podría darse por el aumento de actividad de los elementos contráctiles. Sin embargo, la secuencia de activación sufre importantes cambios, de manera que los cambios en rendimiento estarían asociados principalmente con la disminución en la capacidad de trasmitir la potencia en sentido proximal distal.

  12. Unconventional vertical word-order impairs reading.

    2011-01-01

    Western written languages unfold across both the horizontal (from left to right) and the vertical (from top to bottom) dimensions. Culturally determined horizontal reading/writing habits are so pervasive that their influence can be found not only in visual scanning but also in performance across different domains and tasks. However, little is known on the effects of vertical word order. In the present study, a lexical decision task is used to show that reading performance is less efficient when verbal material is vertically arranged following a bottom-to-top order.

    Adami, N.; Caps, H.

    2015-01-01

    Surface tension profiles in vertical soap films are experimentally investigated. Measurements are performed by introducing deformable elastic objets in the films. The shape adopted by those objects once set in the film is related to the surface tension value at a given vertical position by numerically solving the adapted elasticity equations. We show that the observed dependency of the surface tension versus the vertical position is predicted by simple modeling that takes into account the mechanical equilibrium of the films coupled to previous thickness measurements.

    Full Text Available O salto vertical é inerente à prática do voleibol e demanda grande capacidade de geração de força e trabalho da musculatura envolvida, principalmente do músculo quadríceps. Devido a esta demanda, desequilíbrios entre os músculos extensores e flexores podem estar presentes, levando à sobrecarga das estruturas musculotendíneas da articulação do joelho. Sendo assim, torna-se necessário o estabelecimento de parâmetros de função muscular relacionados a esta articulação em atletas de voleibol. Portanto o objetivo do presente estudo foi avaliar, através de dinamometria isocinética, torque máximo, trabalho máximo, razão agonista/antagonista e índice de fadiga de flexores e extensores de joelho em duas categorias do voleibol. Os testes isocinéticos de flexão e extensão do joelho foram realizados no modo concêntrico-concêntrico, na posição sentada, nas velocidades de 60 e 300º/s em 36 atletas (20 da categoria Infanto-Juvenil e 16 da Juvenil. Os dados possibilitaram estabelecer parâmetros de função muscular da articulação do joelho em atletas das Seleções Brasileiras Infanto-Juvenil e Juvenil de Voleibol Masculino do ano de 2003. Estes atletas apresentaram valores de torque máximo e trabalho máximo normalizados pela massa corporal para quadríceps superiores às médias da população de atletas e não-atletas. Quando comparadas as categorias, os atletas juvenis apresentaram significativamente valores maiores de razão agonista/antagonista e trabalho máximo de flexores de joelhos na velocidade de 60°/s. Além disso, a razão agonista/antagonista foi inferior ao valor de referência esperado em ambas as categorias, caracterizando a predominância da musculatura extensora sobre a flexora. O índice de fadiga encontra-se próximo ao esperado para a maior parte dos atletas. O presente estudo pode servir de base para comparações em futuros estudos que avaliem a função muscular isocinética de atletas de voleibol

    lasting a few hundred thousand years as the island migrates over a broad flexural arch related to isostatic compensation of a nearby active volcano. The arch is located about 190±30 km away from the center of volcanic activity and is also related to the rejuvenated volcanic stage on the islands. Reefs on Oahu that are uplifted several tens of m above sea level are the primary evidence for uplift as the islands over-ride the flexural arch. At the other end of the movement spectrum, both in terms of magnitude and length of response, are the rapid uplift and subsidence that occurs as magma is accumulated within or erupted from active submarine volcanoes. These changes are measured in days to years and are of cm to m variation; they are measured using leveling surveys, tiltmeters, EDM and GPS above sea level and pressure gauges and tiltmeters below sea level. Other acoustic techniques to measure such vertical movement are under development. Elsewhere, evidence for subsidence of volcanoes is also widespread, ranging from shallow water carbonates on drowned Cretaceous guyots, to mapped shoreline features, to the presence of subaerially-erupted (degassed) lavas on now submerged volcanoes. Evidence for uplift is more limited, but includes makatea islands with uplifted coral reefs surrounding low volcanic islands. These are formed due to flexural uplift associated with isostatic loading of nearby islands or seamounts. In sum, oceanic volcanoes display a long history of subsidence, rapid at first and then slow, sometimes punctuated by brief periods of uplift due to lithospheric loading by subsequently formed nearby volcanoes.

  18. Vertical vergence adaptation produces an objective vertical deviation that changes with head tilt.

    To document the cyclovertical ocular motor mechanism used for vertical fusion in healthy subjects, and to explore whether vertical vergence training in healthy individuals can produce objectively confirmed vertical deviations that change with head tilt, revealing a basic mechanism that can produce a pattern of misalignment in an otherwise normal ocular motor system that is similar to superior oblique muscle paresis (SOP). Seven subjects with normal orthoptic examinations were adapted to vertical image disparities using our tilting haploscopic eye-tracking apparatus presenting concentric circle targets without torsional cues. Static eye positions were recorded with head straight and when tilted 45 degrees to the left and right, during both binocular and monocular viewing. Vertical fusional vergence was accompanied by a cycloversion, with the downward-moving eye intorting and the upward-moving eye extorting, implicating primary involvement of the oblique extraocular muscles. After adaptation to the slowly increasing vertical target separation, all subjects developed a temporary vertical deviation in the straight ahead position that increased with head tilt to one side and decreased with head tilt to the other side. These results not only show that head-tilt-dependent changes in vertical deviation are not necessarily pathognomonic for SOP, but also, and more importantly, suggest mechanisms that can mimic SOP and suggest a possible role for vertical vergence training in reducing deviations and thus the amount of head tilt required for fusion. Ultimately, vertical vergence training may provide an adjunct or alternative to extraocular muscle surgery in selected cases.

  20. Thermal vertical bimorph actuators and their applications

    CERN Document Server

    Sehr, H J

    2002-01-01

    In this thesis, a novel concept for lateral actuators based on vertical bimorphs is presented. Vertical bimorphs consist of silicon beams side-coated with aluminium, which bend when heated due to the different thermal expansion coefficients of the two materials causing a displacement in the wafer plane. The heating of the actuator is provided by an electrical current through the silicon beam. The simplest implementation of a vertical bimorph actuator is a clamped-clamped beam. To obtain higher deflections, a meander shaped actuator has been designed. By combining four meander actuators, a two-dimensional positioning stage has been realised. The meander actuator has also been applied for normally closed and normally open micro-relays. Analytical calculations and ANSYS simulations have been carried out to predict the physical behaviour of the bimorph devices, including temperature distribution, static deflection, vertical stiffness, thermal time constant and lateral resonances. For both the clamped-clamped beam...

    The probabilistic distribution of the vertical extent of collision damage is an important and somewhat controversial component of the proposed IMO harmonized damage stability regulations for cargo and passenger ships. The only pre-existing vertical distribution, currently used in the international...... cargo ship regulations, was based on a very simplified presumption of bow heights. This paper investigates the development of this damage extent distribution based on three independent methodologies; actual casualty measurements, world fleet bow height statistics, and collision simulation modeling...

Body weight was recorded daily and blood samples collected every 6 days. At day 12, pigs were orally dosed with BrdU and 12 h later, satellite cells were isolated. Satellite cells were also cultured <em>in vitroem> for 7 days to determine if PO4 nutrition alters their ability to proceed through their myogenic lineage. Dietary PO4 deficiency resulted in reduced (<em>P> < 0.05 sera PO4 and parathyroid hormone (PTH concentrations, while supra-adequate dietary PO4 improved (<em>P> < 0.05 feed conversion efficiency as compared to the PO4 adequate group. <em>In vivoem> satellite cell proliferation was reduced (<em>P> < 0.05 among the PO4 deficient pigs, and these cells had altered <em>in vitroem> expression of markers of myogenic progression.

  11. A Physician's Perspective On Vertical Integration.

    Science.gov (United States)

    Berenson, Robert A

    2017-09-01

    Vertical integration has been a central feature of health care delivery system change for more than two decades. Recent studies have demonstrated that vertically integrated health care systems raise prices and costs without observable improvements in quality, despite many theoretical reasons why cost control and improved quality might occur. Less well studied is how physicians view their newfound partnerships with hospitals. In this article I review literature findings and other observations on five aspects of vertical integration that affect physicians in their professional and personal lives: patients' access to physicians, physician compensation, autonomy versus system support, medical professionalism and culture, and lifestyle. I conclude that the movement toward physicians' alignment with and employment in vertically integrated systems seems inexorable but that policy should not promote such integration either intentionally or inadvertently. Instead, policy should address the flaws in current payment approaches that reward high prices and excessive service use-outcomes that vertical integration currently produces.

    There are no studies exploring the development of vertical saccades in large populations of children. In this study, we examined the development of vertical saccades in sixty-nine children. Binocular eye movements were recorded using an infrared video oculography system [Mobile EBT(®), e(ye)BRAIN], and movements from both eyes had been analyzed. The gain and the peak velocity of vertical saccades show an up-down asymmetry. Latency value decreases with the age of children, and it does not depend on the direction of the saccades; in contrast, the gain and the peak velocity values of vertical saccades are stable during childhood. We suggest that the up-down asymmetry is developed early, or is innate, in humans. Latencies of vertical saccades develop with the age of children, in relationship with the development of the cortical network responsible for the saccade preparation. In contrast, the precision and the peak velocity are not age-dependent as they are controlled by the cerebellum and brainstem structures.

    2012-01-01

    Full Text Available Nanowires (NWs/Ag sheath composites were produced to investigate plasmonic coupling between vertically aligned NWs for surface-enhanced Raman scattering (SERS applications. In this investigation, two types of vertical NW arrays were studied; those of ZnO NWs grown on nanosphere lithography patterned sapphire substrate via vapor-liquid-solid (VLS mechanism and Si NW arrays produced by wet chemical etching. Both types of vertical NW arrays were coated with a thin layer of silver by electroless silver plating for SERS enhancement studies. The experimental results show extremely strong SERS signals due to plasmonic coupling between the NWs, which was verified by COMSOL electric field simulations. We also compared the SERS enhancement intensity of aligned and random ZnO NWs, indicating that the aligned NWs show much stronger and repeatable SERS signal than those grown in nonaligned geometries.

    Vertical cable acquisition is performed by deploying a certain number of vertical hydrophone arrays in the water column, and subsequently shooting a source point on top of it. The advantage of this particular geometry is that gives a data set with all azimuths included. Therefore a more complete 3-D velocity model can be derived. In this paper there are presented some results from the Fuji survey in the Gulf of Mexico. Based on these results, improved geometries and review recommendations for future surveys are discussed. 7 figs.

  7. Electrostatic comb drive for vertical actuation

    Energy Technology Data Exchange (ETDEWEB)

    Lee, A. P., LLNL

    1997-07-10

    The electrostatic comb finger drive has become an integral design for microsensor and microactuator applications. This paper reports on utilizing the levitation effect of comb fingers to design vertical-to-the-substrate actuation for interferometric applications. For typical polysilicon comb drives with 2 {micro}m gaps between the stationary and moving fingers, as well as between the microstructures and the substrate, the equilibrium position is nominally 1-2 {micro}m above the stationary comb fingers. This distance is ideal for many phase shifting interferometric applications. Theoretical calculations of the vertical actuation characteristics are compared with the experimental results, and a general design guideline is derived from these results. The suspension flexure stiffnesses, gravity forces, squeeze film damping, and comb finger thicknesses are parameters investigated which affect the displacement curve of the vertical microactuator. By designing a parallel plate capacitor between the suspended mass and the substrate, in situ position sensing can be used to control the vertical movement, providing a total feedback-controlled system. Fundamentals of various capacitive position sensing techniques are discussed. Experimental verification is carried out by a Zygo distance measurement interferometer.

  8. Vertical distribution of natural radionuclides in soils

    Lozano J. C.

    2012-04-01

    Full Text Available Low-level alpha spectrometry techniques using semiconductor detectors (PIPS and liquid scintillation counters (LKB Quantulus 1220™ were used in order to determine the activity concentration of 238U, 232Th, 234U, 230Th, 226Ra, and 210Pb in soil samples. The soils were collected from an old disused uranium mine located in southwest Spain. The soils were selected with different levels of influence from the installation, in such a way that they had different levels of radioactive contamination. The vertical profiles in the soils (down to 40 cm depth were studied in order to evaluate the vertical distribution of the natural radionuclides. The possible contamination of subsurface waters depends strongly on vertical migration, and the transfer to plants (herbs, shrubs, and trees also will depend on the distribution of the radionuclides in the root zone. The study of the activity ratios between radionuclides belonging to the same series allowed us to assess the differing behaviour of the radionuclides involved. The vertical profiles for these radionuclides were different at each sampling point, showing the local impact of the installation. However, the profiles per point were similar for the long-lived radionuclides of the 238TJ series (238U, 234U, 230Th, and 226Ra. Also, a major disequilibrium was observed between 210Pb and 226Ra in the surface layer, due to 222Rn emanation and subsequent surface deposition of 210Pb.

    Science.gov (United States)

    Holstein, Daniel M.; Paris, Claire B.; Vaz, Ana C.; Smith, Tyler B.

    2016-03-01

    Whether mesophotic reefs will behave as refugia for corals threatened by global climate change and coastal development depends on vertical exchange of larvae between diverse habitats. Here we use a biophysical model of larval dispersal to estimate vertical connectivity of a broadcasting ( Orbicella faveolata) and a brooding ( Porites astreoides) species of coral in the US Virgin Islands. Modeling predicts subsidy to shallow areas by mesophotic larvae of both species based on local hydrology, adult reproductive characteristics, larval traits, and a wide range of scenarios developed to test depth-sensitive factors, such as fertilization rates and post-settlement survivorship. In extreme model scenarios of reduced fertilization and post-settlement survivorship of mesophotic larvae, 1-10 % local mesophotic subsidy to shallow recruitment is predicted for both species, which are demographically significant. Although direct vertical connectivity is higher for the broadcaster, the brooder demonstrates higher local multigenerational vertical connectivity, which suggests that local P. astreoides populations are more resilient than those of O. faveolata, and corroborates field studies. As shallow habitat degrades, mesophotic-shallow subsidy is predicted to increase for both species. This study is the first of its kind to simulate larval dispersal and settlement between habitats of different depths, and these findings have local, regional, and global implications for predicting and managing coral reef persistence in a changing climate.

  19. The Vertical Farm: A Review of Developments and Implications for the Vertical City

    Directory of Open Access Journals (Sweden)

    Kheir Al-Kodmany

    2018-02-01

    Full Text Available This paper discusses the emerging need for vertical farms by examining issues related to food security, urban population growth, farmland shortages, “food miles”, and associated greenhouse gas (GHG emissions. Urban planners and agricultural leaders have argued that cities will need to produce food internally to respond to demand by increasing population and to avoid paralyzing congestion, harmful pollution, and unaffordable food prices. The paper examines urban agriculture as a solution to these problems by merging food production and consumption in one place, with the vertical farm being suitable for urban areas where available land is limited and expensive. Luckily, recent advances in greenhouse technologies such as hydroponics, aeroponics, and aquaponics have provided a promising future to the vertical farm concept. These high-tech systems represent a paradigm shift in farming and food production and offer suitable and efficient methods for city farming by minimizing maintenance and maximizing yield. Upon reviewing these technologies and examining project prototypes, we find that these efforts may plant the seeds for the realization of the vertical farm. The paper, however, closes by speculating about the consequences, advantages, and disadvantages of the vertical farm’s implementation. Economic feasibility, codes, regulations, and a lack of expertise remain major obstacles in the path to implementing the vertical farm.

    2017-04-27

    We examined plastic changes in the vestibulo-ocular reflex (VOR) during low-frequency vertical head rotation, a condition under which otolith inputs from the vestibular system are essential for VOR generation. For adaptive conditioning of the vertical VOR, 0.02Hz sinusoidal pitch rotation for one hour about the earth's horizontal axis was synchronized with out-of-phase vertical visual stimulation from a random dot pattern. A vertical VOR was well evoked when the upright animal rotated around the earth-horizontal axis (EHA) at low frequency due to the changing gravity stimulus and dynamic stimulation of the otoliths. After adaptive conditioning, the amplitude of the vertical VOR increased by an average of 32.1%. Our observations showing plasticity in the otolithic contribution to the VOR may provide a new strategy for visual-vestibular mismatch training in patients with otolithic disorders. This low-frequency vertical head rotation protocol also provides a model for investigating the mechanisms underlying the adaptation of VORs mediated by otolith activation.

The driving current is increased by 5-fold due to the inherent vertically stacked five-level nanowires, thus showing good feasibility of three-dimensional integration-based high performance transistor. The developed fabrication process, which is simple and reproducible, is used to create multiple stiction-free and uniformly sized nanowires with the aid of the one-route all-dry etching process (ORADEP). Furthermore, the proposed FET is revamped to create nonvolatile memory with the adoption of a charge trapping layer for enhanced practicality. Thus, this research suggests an ultimate design for the end-of-the-roadmap devices to overcome the limits of scaling.

    Active stabilisation showed a relative locked linewidth of approx 3 kHz. Coarse tuning over 7 nm was achieved using a 3-plate birefingent filter plate while fine-tuning using cavity length change allowed tuning over 250 MHz. Vertical external cavity semiconductor lasers have emerged as an interesting technology based on current vertical cavity semiconductor laser knowledge. High power output into a single transverse mode has attracted companies requiring good fibre coupling for telecommunications systems. The structure comprises of a grown semiconductor Bragg reflector topped with a multiple quantum well gain region. This is then included in an external cavity. This device is then optically pumped to promote laser action. Theoretical modelling of AIGaAs based VECSEL structures was undertaken, showing the effect of device design on laser characteristics. A simple 3-mirror cavity was constructed to assess the static characteristics of the structure. Up to 153 mW of output power was achieved in a single transver...

    Much efforts have been made for the realization of hybrid Josephson junctions incorporating various materials for the fundamental studies of exotic physical phenomena as well as the applications to superconducting quantum devices. Nonetheless, the efforts have been hindered by the diffusive nature of the conducting channels and interfaces. To overcome the obstacles, we vertically sandwiched a cleaved graphene monoatomic layer as the normal-conducting spacer between superconducting electrodes. The atomically thin single-crystalline graphene layer serves as an ultimately short conducting channel, with highly transparent interfaces with superconductors. In particular, we show the strong Josephson coupling reaching the theoretical limit, the convex-shaped temperature dependence of the Josephson critical current and the exceptionally skewed phase dependence of the Josephson current; all demonstrate the bona fide short and ballistic Josephson nature. This vertical stacking scheme for extremely thin transparent spacers would open a new pathway for exploring the exotic coherence phenomena occurring on an atomic scale.

    Georgakis, Christos; Ingólfsson, Einar Thór

    2008-01-01

    In this paper, a novel, accurate and readily codifiable methodology for the prediction of vertical footbridge response is presented. The methodology is based on the well-established response spectrum approach used in the majority of the world’s current seismic design codes of practice. The concept...... of a universally applicable reference response spectrum is introduced, from which the pedestrian-induced vertical response of any footbridge may be determined, based on a defined “event” and the probability of occurrence of that event. A series of Monte Carlo simulations are undertaken for the development...... of a reference response spectrum. The simulations use known statistical data for pedestrian and population walking characteristics to generate loads for a 50m long simply-supported bridge, with a fixed level of damping and a mean pedestrian flow rate of 1 pedestrian / sec.

    Full Text Available This paper develops a different approach for enhancing the performance of Vertical Axis Wind Turbines for the use in the urban or rural environment and remote isolated residential areas. Recently the vertical axis wind turbines (VAWT have become more attractive due to the major advantages of this type of turbines in comparison to the horizontal axis wind turbines. We aim to enhance the overall performance of the VAWT by adding a second set of blades (3 x 2=6 blades following the rules of biplane airplanes. The model has been made to operate at a maximum power in the range of the TSR between 2 to 2.5. The performances of the VAWT were investigated numerically and experimentally and justify the new proposed design.

  11. Predicting Vertical Motion within Convective Storms

    Science.gov (United States)

    van den Heever, S. C.

    2016-12-01

    Convective storms are both beneficial in the fresh water they supply and destructive in the life-threatening extreme weather they produce. They are found throughout the tropics and midlatitudes, vary in structure from isolated to highly organized systems, and are the sole source of precipitation in many regions of Earth. Convective updrafts and downdrafts plays a crucial role in cloud and precipitation formation, latent heating, water vapor transport, storm organization, and large-scale atmospheric circulations such as the Hadley and Walker cells. These processes, in turn, impact the strength and longevity of updrafts and downdrafts through complex, non-linear feedbacks. In spite of the significant influence of convective updrafts and downdrafts on the weather and climate system, accurately predicting vertical motion using numerical models remains challenging. In high-resolution cloud-resolving models where vertical motion is normally resolved, significant biases exist in the predicted profiles of updraft and downdraft velocities, at least for the limited cases where observational data have been available for model evaluation. It has been suggested that feedbacks between the vertical motion and microphysical processes may be one cause of these discrepancies, however, our understanding of these feedbacks remains limited. In this talk, the results of a small field campaign conducted over northeastern Colorado designed to observe storm vertical motion and cold pool characteristics within isolated and organized deep convective storms will be described. High frequency radiosonde, radar and drone measurements of a developing through mature supercell storm updraft and cold pool will be presented and compared with RAMS simulations of the same supercell storm. An analysis of the feedbacks between the storm dynamical and microphysical processes will be presented, and implications for regional and global modeling of severe storms will be discussed.

    Suchomel, Timothy J; Lamont, Hugh S; Moir, Gavin L

    2016-06-01

    This review article discusses previous postactivation potentiation (PAP) literature and provides a deterministic model for vertical jump (i.e., squat jump, countermovement jump, and drop/depth jump) potentiation. There are a number of factors that must be considered when designing an effective strength-power potentiation complex (SPPC) focused on vertical jump potentiation. Sport scientists and practitioners must consider the characteristics of the subject being tested and the design of the SPPC itself. Subject characteristics that must be considered when designing an SPPC focused on vertical jump potentiation include the individual's relative strength, sex, muscle characteristics, neuromuscular characteristics, current fatigue state, and training background. Aspects of the SPPC that must be considered for vertical jump potentiation include the potentiating exercise, level and rate of muscle activation, volume load completed, the ballistic or non-ballistic nature of the potentiating exercise, and the rest interval(s) used following the potentiating exercise. Sport scientists and practitioners should design and seek SPPCs that are practical in nature regarding the equipment needed and the rest interval required for a potentiated performance. If practitioners would like to incorporate PAP as a training tool, they must take the athlete training time restrictions into account as a number of previous SPPCs have been shown to require long rest periods before potentiation can be realized. Thus, practitioners should seek SPPCs that may be effectively implemented in training and that do not require excessive rest intervals that may take away from valuable training time. Practitioners may decrease the necessary time needed to realize potentiation by improving their subject's relative strength.

  15. Vertical and horizontal seismometric observations of tides

    Science.gov (United States)

    Lambotte, S.; Rivera, L.; Hinderer, J.

    2006-01-01

    Tidal signals have been largely studied with gravimeters, strainmeters and tiltmeters, but can also be retrieved from digital records of the output of long-period seismometers, such as STS-1, particularly if they are properly isolated. Horizontal components are often noisier than the vertical ones, due to sensitivity to tilt at long periods. Hence, horizontal components are often disturbed by local effects such as topography, geology and cavity effects, which imply a strain-tilt coupling. We use series of data (duration larger than 1 month) from several permanent broadband seismological stations to examine these disturbances. We search a minimal set of observable signals (tilts, horizontal and vertical displacements, strains, gravity) necessary to reconstruct the seismological record. Such analysis gives a set of coefficients (per component for each studied station), which are stable over years and then can be used systematically to correct data from these disturbances without needing heavy numerical computation. A special attention is devoted to ocean loading for stations close to oceans (e.g. Matsushiro station in Japon (MAJO)), and to pressure correction when barometric data are available. Interesting observations are made for vertical seismometric components; in particular, we found a pressure admittance between pressure and data 10 times larger than for gravimeters for periods larger than 1 day, while this admittance reaches the usual value of -3.5 nm/s 2/mbar for periods below 3 h. This observation may be due to instrumental noise, but the exact mechanism is not yet understood.

  16. Vertically integrated flow in stratified aquifers

    Science.gov (United States)

    Strack, Otto D. L.

    2017-05-01

    We present a set of continuous discharge potentials that can be used to determine the vertically integrated flow in stratified aquifers. The method applies to cases where the boundaries are vertical and either the hydraulic head is given, or the boundary is a seepage face, or the integrated discharge is given. The approach is valid for cases of given recharge through the upper and/or lower boundaries of the aquifer. The method is valid for any values of hydraulic conductivity; there are no limitations of the contrast for the method to be valid. The flows in the strata may be either confined or unconfined, and locally perched conditions may exist, but the effect of capillarity is not included. The hydraulic head is determined by applying the Dupuit-Forchheimer approximation. The main advantage of the approach is that very complex conditions in stratified aquifer systems, including locally perched conditions and extremely complex flow systems can be treated in a relatively straight forward approach by considering only the vertically integrated flow rates. The approach is particularly useful for assessing groundwater sustainability, as a model to be constructed prior to developing a fully three-dimensional numerical model.

  17. Dynamic stiffness of suction caissons - vertical vibrations

    2006-12-15

    The dynamic response of offshore wind turbines are affected by the properties of the foundation and the subsoil. The purpose of this report is to evaluate the dynamic soil-structure interaction of suction caissons for offshore wind turbines. The investigation is limited to a determination of the vertical dynamic stiffness of suction caissons. The soil surrounding the foundation is homogenous with linear viscoelastic properties. The dynamic stiffness of the suction caisson is expressed by dimensionless frequency-dependent dynamic stiffness coefficients corresponding to the vertical degree of freedom. The dynamic stiffness coefficients for the foundations are evaluated by means of a dynamic three-dimensional coupled Boundary Element/Finite Element model. Comparisons are made with known analytical and numerical solutions in order to evaluate the static and dynamic behaviour of the Boundary Element/Finite Element model. The vertical frequency dependent stiffness has been determined for different combinations of the skirt length, Poisson's ratio and the ratio between soil stiffness and skirt stiffness. Finally the dynamic behaviour at high frequencies is investigated. (au)

    The successful control of strongly shaped plasmas on the Korea Superconducting Tokamak Advanced Research (KSTAR) device requires active feedback of fast motion of the plasma vertical position by the use of internal normal conducting coils (IVC). This has required new electronics to supply relative flux loop differences, for zp, and voltage loop differences, for dzp/dt, as well as a novel technique (Zfast) to use a high-pass filter, typically 1 Hz, on the error in the signal in the feedback loop. Use of Zfast avoids the potential contention encountered when the internal coil attempts to perform control of the plasma shape which should be controlled by the slower and more powerful superconducting coils. A common problem of this contention is saturation of the IVC and loss of fast vertical control. This is eliminated by proper use of the Zfast. A Ziegler-Nichols relay feedback system was used to fine tune the required feedback gains. The selection of the magnetic sensors, filter time constants, control gains and of the Zfast control strategy which allowed vertically stable operation at a plasma elongation, kappa. of up to 2.16 at li = 1.15 and Betap = 2.4 will be discussed which is beyond the design reference of KSTAR of kappa = 2.0 at li = 1.2 and Betap = 1.9.

    The National Spherical Torus Experiment Upgrade (NSTX-U) completed its first run campaign in 2016, including commissioning a larger center-stack and three new tangentially aimed neutral beam sources. NSTX-U operates at increased aspect ratio due to the larger center-stack, making vertical stabilization more challenging. Since ST performance is improved at high elongation, improvements to the vertical control system were made, including use of multiple up-down-symmetric flux loop pairs for real-time estimation, and filtering to remove noise. Similar operating limits to those on NSTX (in terms of elongation and internal inductance) were achieved, now at higher aspect ratio. To better understand the observed limits and project to future operating points, a database of vertical displacement events and vertical oscillations observed during the plasma current ramp-up on NSTX/NSTX-U has been generated. Shots were clustered based on the characteristics of the VDEs/oscillations, and the plasma parameter regimes associated with the classes of behavior were studied. Results provide guidance for scenario development during ramp-up to avoid large oscillations at the time of diverting, and provide the means to assess stability of target scenarios for the next campaign. Results will also guide plans for improvements to the vertical control system. Work supported by U.S. D.O.E. Contract No. DE-AC02-09CH11466.

    Full Text Available A green synthesis route for the production of silver nanoparticles using methanol extract from <em>Solanum> <em>xanthocarpum> berry (SXE is reported in the present investigation. Silver nanoparticles (AgNps, having a surface plasmon resonance (SPR band centered at 406 nm, were synthesized by reacting SXE (as capping as well as reducing agent with AgNO3 during a 25 min process at 45 °C. The synthesized AgNps were characterized using UV–Visible spectrophotometry, powdered X-ray diffraction, and transmission electron microscopy (TEM. The results showed that the time of reaction, temperature and volume ratio of SXE to AgNO3 could accelerate the reduction rate of Ag+ and affect the AgNps size and shape. The nanoparticles were found to be about 10 nm in size, mono-dispersed in nature, and spherical in shape. <em>In> <em>vitro> anti-<em>Helicobacter> <em>pylori> activity of synthesized AgNps was tested against 34 clinical isolates and two reference strains of <em>Helicobacter> <em>pylori> by the agar dilution method and compared with AgNO3 and four standard drugs, namely amoxicillin (AMX, clarithromycin (CLA, metronidazole (MNZ and tetracycline (TET, being used in anti-<em>H.> <em>pylori> therapy. Typical AgNps sample (S1 effectively inhibited the growth of <em>H.> <em>pylori>, indicating a stronger anti-<em>H.> <em>pylori> activity than that of AgNO3 or MNZ, being almost equally potent to TET and less potent than AMX and CLA.

    This research tries to make advancement in GPS signal processing to estimate the interseismic vertical deformation field at western part of Sumatra Island. The data derived by Continuous Global Positioning System (CGPS) from Badan Informasi Geospasial (BIG) between 2010 and 2012. GPS Analyze at Massachusetts Institute of Technology (GAMIT) software and Global Kalman Filter (GLOBK) software are used to process the GPS signal to estimate the vertical velocities of the CGPS station. In order to minimize noise due to atmospheric delay, Vienna Mapping Function 1 (VMF1) is used as atmospheric parameter model and include daily IONEX file provided by the Center for Orbit Determination in Europe (CODE) as well. It improves GAMIT daily position accuracy up to 0.8 mm. In a second step of processing, the GLOBK is used in order to estimate site positions and velocities in the ITRF08 reference frame. The result shows that the uncertainties of estimated displacement velocity at all CGPS stations are smaller than 1.5 mm/yr. The subsided deformation patterns are seen at the northern and southern part of west Sumatra. The vertical deformation at northern part of west Sumatra indicates postseismic phase associated with the 2010 and 2012 Northern Sumatra earthquakes and also the long-term postseismic associated with the 2004 and 2005 Northern Sumatra earthquakes. The uplifted deformation patterns are seen from Bukit Tinggi to Seblat which indicate a long-term interseismic phase after the 2007 Bengkulu earthquake and 2010 Mentawai earthquake. GANO station shows a subsidence at rate 12.25 mm/yr, indicating the overriding Indo-Australia Plate which is dragged down by the subducting Southeast Asian Plate.

    We study triangulations $\\\\cal T$ defined on a closed disc $X$ satisfying the following condition: In the interior of $X$, the valence of all vertices of $\\\\cal T$ except one of them (the irregular vertex) is $6$. By using a flat singular Riemannian metric adapted to $\\\\cal T$, we prove a uniqueness theorem when the valence of the irregular vertex is not a multiple of $6$. Moreover, for a given integer $k >1$, we exhibit non isomorphic triangulations on $X$ with the same boundary, and with a unique irregular vertex whose valence is $6k$.

Does the presence of “premium” or high-quality products in a product line enhance brand equity? Conversely, does the presence of “economy” or low-quality products in a product line diminish brand equity? Economists and marketing researchers refer to variation in quality levels of products within a category as “vertical” differentiation, whereas variation in the function or “category” of ...

    A photodiode consisting of nanopillars of thin-film silicon p-i-n on an array of vertically aligned carbon nanotubes (CNTs) with a noncontinuous cathode electrode is demonstrated. The structure exploits the intrinsic enhancement of the CNTs' electric field, which leads to reduction in the photodiode's operating voltage and response time and enhancement of optical coupling due to better light trapping, as compared with the conventional planar photodiode. These improvements translate to higher resolution and higher frame rate flat-panel imaging systems for a broad range of applications, including computed tomography and particle detection.

    Full Text Available A novel vertical meandering technique to reduce the lateral size of a planar printed antenna is presented. It is implemented by dividing a conventional spiral patch into a different number of segments and placing them on different sides of the microwave substrate with vias as the connections. To confirm the validity of this technique, measured electrical performance and radiation characteristics of five antennas with different numbers of segments are compared. The smallest antenna is reduced in size by 84% when compared with the conventional printed spiral antenna.

    NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this full-circle view of the rover's surroundings during the 1,818th Martian day, or sol, of Opportunity's surface mission (March 5, 2009). South is at the center; north at both ends. This view is presented as a vertical projection with geometric seam correction. North is at the top. The rover had driven 80.3 meters (263 feet) southward earlier on that sol. Tracks from the drive recede northward in this view. The terrain in this portion of Mars' Meridiani Planum region includes dark-toned sand ripples and lighter-toned bedrock.

    This paper discusses some recent measurements of third and fourth moments of vertical differences (shears) of longitudinal velocity fluctuations obtained in unstable air at the NASA 150 m meteorological tower site at Cape Kennedy, Fla. Each set of measurements consisted of longitudinal velocity fluctuation time histories obtained at the 18, 30, 60, 90, 120 and 150 m levels, so that 15 wind-shear time histories were obtained from each set of measurements. It appears that the distribution function of the longitudinal wind fluctuations at two levels is not bivariate Gaussian. The implications of the results relative to the design and operation of aerospace vehicles are discussed.-

    Full Text Available Modules for Vertical Urban Gardens (MHUG are a hybrid of vertical gardens and urban agriculture. Vertical gardens have been recognized for the past 2500 years, mainly in the form of the Hanging Gardens of Babylon, while urban agriculture is being practiced today by more than 700 million people worldwide. The benefits that MHUV offers are multiple, but perhaps the most significant is the consumption of foods free of chemicals, free of GMO’s, irrigated with potable water, and that are 100% organic. It is presented a “culinary and medicinal module” that can be implemented in the kitchen area, on roofs, terraces, balconies or patios, where species such as thyme, mint, peppermint, parsley, lemon balm and rosemary can be at hand when preparing dishes. The module consists of three plastic baskets that are recyclable and resistant to decay. Each basket has four rows with space for fourteen seedlings. The baskets are first lined on the interior with a black geotextile, and then are covered with a mesh (polisombra which helps support the substrate and seedlings. Each basket rests on a structure made of recycled wood (from pallets or crates that both holds the basket vertically and serves as a rain cover. The cages measure 0.33m by 0.55m by 0.14m. Each module comes with hosing and connectors for a drip irrigation system, and an instructional manual. The modules demonstrate the benefits of urban agriculture combined with the beauty and modality of vertical gardens, leading to useful applications for food production and decoration in the spaces where vertical urban gardens are possible.

    2016-07-01

    Full Text Available Our intuitive knowledge of physics mechanics, i.e. knowledge defined through personal experience about velocity, acceleration, motion causes, etc., is often wrong. This research examined whether similar misconceptions occur systematically in the case of vertical projectiles launched upwards. The first experiment examined inferences of velocity and acceleration of the ball moving vertically upwards, while the second experiment examined whether the mass of the thrown ball and force of the throw have an impact on the inference. The results showed that more than three quarters of the participants wrongly assumed that maximum velocity and peak acceleration did not occur at the initial launch of the projectile. There was no effect of object mass or effect of the force of the throw on the inference relating to the velocity and acceleration of the ball. The results exceed the explanatory reach of the impetus theory, most commonly used to explain the naive understanding of the mechanics of object motion. This research supports that the actions on objects approach and the property transmission heuristics may more aptly explain the dissidence between perceived and actual implications in projectile motion.

    Corals rely on water flow for the supply of nutrients, particles and energy. Therefore, modeling of processes that take place inside the reef, such as respiration and photosynthesis, relies on models that describe the flow and concentration fields. Due to the high spatial heterogeneity of branched coral reefs, depth average models are usually applied. Such an average approach is insufficient when the flow spatial variation inside the reef is of interest. We report on measurements of vertical variations of drag force that are needed for developing 3D flow models. Coral skeletons were densely arranged along a laboratory flume. Two corals were CT-scanned and replaced with horizontally sliced 3D printed replicates. Drag profiles were measured by connecting the slices to costume drag sensors and velocity profiles were measured using a LDV. The measured drag of whole colonies was in excellent agreement with previous studies; however, these studies never showed how drag varies inside the reef. In addition, these distributions of drag force showed an excellent agreement with momentum balance calculations. Based on the results, we propose a new drag model that includes the dispersive stresses, and consequently displays reduced vertical variations of the drag coefficient.

  6. Vertical Crossing Angle in IR8

    2013-01-01

    The operation of the LHCb spectrometer dipole has a considerably larger and more challenging impact on the geometry of the LHC beams than the magnets in the high luminosity regions [1]. The integrated dipole field of 4 Tm deflects the beams in the horizontal plane, and using a set of three dipole magnets, called "compensators" a closed horizontal orbit bump is created. This paper summarizes the basic layout of the beam geometry in IR8 under the influence of the LHCb dipole and its compensators and shows the theoretically expected beam orbits, envelopes and aperture needs in the originally designed version. LHCb operation with both field polarities leads to unequal net crossing angles between the two beams and affects the experiment acceptance. It had been proposed therefore to establish a LHC operation mode where the originally designed horizontal crossing angle is shifted at high energy into the vertical plane leading to a vertical crossing scheme at luminosity operation. The new scheme has been successfully...

  7. The capillary interaction between two vertical cylinders

    Cooray, Himantha

    2012-06-27

    Particles floating at the surface of a liquid generally deform the liquid surface. Minimizing the energetic cost of these deformations results in an inter-particle force which is usually attractive and causes floating particles to aggregate and form surface clusters. Here we present a numerical method for determining the three-dimensional meniscus around a pair of vertical circular cylinders. This involves the numerical solution of the fully nonlinear Laplace-Young equation using a mesh-free finite difference method. Inter-particle force-separation curves for pairs of vertical cylinders are then calculated for different radii and contact angles. These results are compared with previously published asymptotic and experimental results. For large inter-particle separations and conditions such that the meniscus slope remains small everywhere, good agreement is found between all three approaches (numerical, asymptotic and experimental). This is as expected since the asymptotic results were derived using the linearized Laplace-Young equation. For steeper menisci and smaller inter-particle separations, however, the numerical simulation resolves discrepancies between existing asymptotic and experimental results, demonstrating that this discrepancy was due to the nonlinearity of the Laplace-Young equation. © 2012 IOP Publishing Ltd.

  8. Determinants of Arbovirus Vertical Transmission in Mosquitoes.

    Sebastian Lequime

    2016-05-01

    Full Text Available Vertical transmission (VT and horizontal transmission (HT of pathogens refer to parental and non-parental chains of host-to-host transmission. Combining HT with VT enlarges considerably the range of ecological conditions in which a pathogen can persist, but the factors governing the relative frequency of each transmission mode are poorly understood for pathogens with mixed-mode transmission. Elucidating these factors is particularly important for understanding the epidemiology of arthropod-borne viruses (arboviruses of public health significance. Arboviruses are primarily maintained by HT between arthropod vectors and vertebrate hosts in nature, but are occasionally transmitted vertically in the vector population from an infected female to her offspring, which is a proposed maintenance mechanism during adverse conditions for HT. Here, we review over a century of published primary literature on natural and experimental VT, which we previously assembled into large databases, to identify biological factors associated with the efficiency of arbovirus VT in mosquito vectors. Using a robust statistical framework, we highlight a suite of environmental, taxonomic, and physiological predictors of arbovirus VT. These novel insights contribute to refine our understanding of strategies employed by arboviruses to persist in the environment and cause substantial public health concern. They also provide hypotheses on the biological processes underlying the relative VT frequency for pathogens with mixed-mode transmission that can be tested empirically.

    Brulle, Robert V.

    1983-10-18

    A vertical axis windmill having a rotating structure is provided with a series of articulated vertical blades whose positions are controlled to maintain a constant RPM for the rotating structure, when wind speed is sufficient. A microprocessor controller is used to process information on wind speed, wind direction and RPM of the rotating structure to develop an electrical signal for establishing blade position. The preferred embodiment of the invention, when connected to a utility grid, is designed to generate 40 kilowatts of power when exposed to a 20 mile per hour wind. The control system for the windmill includes electrical blade actuators that modulate the blades of the rotating structure. Blade modulation controls the blade angle of attack, which in turn controls the RPM of the rotor. In the preferred embodiment, the microprocessor controller provides the operation logic and control functions. A wind speed sensor provides inputs to start or stop the windmill, and a wind direction sensor is used to keep the blade flip region at 90.degree. and 270.degree. to the wind. The control system is designed to maintain constant rotor RPM when wind speed is between 10 and 40 miles per hour.

    In this paper, we proposed a dynamical approach to assess vertices' centrality according to the synchronization process of the Kuramoto model. In our approach, the vertices' dynamical centrality is calculated based on the Difference of vertices' Synchronization Abilities (DSA), which are different from traditional centrality measurements that are related to the topological properties. Through applying our approach to complex networks with a clear community structure, we have calculated all vertices' dynamical centrality and found that vertices at the end of weak links have higher dynamical centrality. Meanwhile, we analyzed the robustness and efficiency of our dynamical approach through testing the probabilities that some known vital vertices were recognized. Finally, we applied our dynamical approach to identify community due to its satisfactory performance in assessing overlapping vertices. Our present work provides a new perspective and tools to understand the crucial role of heterogeneity in revealing the interplay between the dynamics and structure of complex networks.

    considering inventory, changes in the underground environment, and theoretical and experimental results. The recipes represent the degraded waste in its weakest condition; simulating 50, 75, and 100% degradation by weight. The percent degradation indicates the anticipated amount of iron corrosion and decomposition of cellulosics, plastics, and rubbers. Samples were die compacted to two pressures, 2.3 and 5.0 MPa. Testing has established that the less degraded the surrogate material is and the higher the compaction stress it undergoes, the stronger the sample is. The 50% degraded surrogate waste material was accepted for use in obtaining input parameters for another WIPP PA model by a conceptual model peer review panel and the EPA. The use of a 50% degraded surrogate waste in vertical flume testing would provide an improved estimate of the waste shear strength and establish consistency between PA models in the approach used to obtain input parameters.

    Full Text Available ResumoEste trabalho teve como objetivo avaliar a estratificação vertical de um remanescente de Floresta Ombrófila Mista na região sul do Paraná. O estudo foi realizado com base em dados provenientes de oito parcelas amostrais permanentes, instaladas nos municípios de General Carneiro, Coronel Domingos Soares e Bituruna, para duas formações distintas sendo: campo com sub-bosque pouco desenvolvido e ralo e floresta densa. Para que o estudo da estratificação se tornasse possível, foram estimadas alturas para as araucárias e para o grupo das folhosas. A estimativa deu-se com base no ajuste de equações para as araucárias e folhosas independentemente. Para a representação da estratificação vertical da floresta, utilizou-se o método h-M, levando em consideração dados de diâmetro e altura coletados em 1998 e 2003. Em trabalhos anteriores o mesmo apresentou dificuldades na visualização da estratificação, não gerando picos abruptos entre um estrato e outro. Foi elaborada, portanto, uma metodologia que proporcionasse uma divisão mais abrupta entre os estratos, através da divisão do banco de dados em três grupos. A metodologia proposta indicou para a formação de campo com sub-bosques pouco desenvolvidos, a existência de três estratos em 1998 e quatro em 2003. Para a floresta densa foram observados para ambos os anos cinco estratos verticais.AbstractThe purpose of this paper was to assess the vertical stratification of an Araucaria Forest in the south of Paraná.

In order to enable the stratification, heights were estimated for the araucaria trees and broad-leaved species. The tree height estimation was based on the adjustment of independent equations

    Variano, E. A.

    2010-12-01

    The objective of this work is to understand the fluxes connecting the water column, substrate, and atmosphere in wetland environments. To do this, analytical, numerical, and laboratory models have been used to quantify the hydrodynamic contributions to vertical fluxes. A key question is whether the hydrodynamic transport can be modeled as a diffusivity, and, if so, what the vertical structure of this diffusivity is. This question will be addressed in a number of flow types and for a number of fluxes. The fluxes of interest are heat, sediment, dissolved gases (such as methane and oxygen) and other dissolved solutes (such as nutrients and pollutants). The flows of interest include: unidirectional current, reversing flow (under waves, seiches, and tides), wind-sheared surface flows, and thermal convection. Rain and bioturbation can be important, but are not considered in the modeling work discussed herein. Specifically, we will present results on gas transport at wind-sheared free surface, sediment transport in unidirectional flow, and heat transfer in an oscillating flow cause by a seiche. All three of these will be used to consider the question of appropriate analytical models for vertical transport. The analytic models considered here are all 1D models that assume homogeneity in the horizontal plane. The numerical models use finite element methods and resolve the flow around individual vegetation stems in an idealized geometry. Laboratory models discussed herein also use an idealized geometry. Vegetation is represented by an array of cylinders, whose geometry is modeled after Scirpus spp. wetlands in Northern California. The laboratory model is constructed in a way that allows optical access to the flow, even in dense vegetation and far from boundaries. This is accomplished by using fluoropolymer plastics to construct vegetation models. The optical access allows us to employ particle image velocimetry (PIV) and planar laser induced fluorescence (PLIF) to measure

    The objective of the study was to assess the use of maximum (Vmax) and final propulsive phase (FPV) bar velocity to predict jump height in the weighted jump squat. FPV was defined as the velocity reached just before bar acceleration was lower than gravity (-9.81 m·s(-2)). Vertical jump height was calculated from the take-off velocity (Vtake-off) provided by a force platform. Thirty swimmers belonging to the National Slovenian swimming team performed a jump squat incremental loading test, lifting 25%, 50%, 75% and 100% of body weight in a Smith machine. Jump performance was simultaneously monitored using an AMTI portable force platform and a linear velocity transducer attached to the barbell. Simple linear regression was used to estimate jump height from the Vmax and FPV recorded by the linear velocity transducer. Vmax (y = 16.577x - 16.384) was able to explain 93% of jump height variance with a standard error of the estimate of 1.47 cm. FPV (y = 12.828x - 6.504) was able to explain 91% of jump height variance with a standard error of the estimate of 1.66 cm. Despite that both variables resulted to be good predictors, heteroscedasticity in the differences between FPV and Vtake-off was observed (r(2) = 0.307), while the differences between Vmax and Vtake-off were homogenously distributed (r(2) = 0.071). These results suggest that Vmax is a valid tool for estimating vertical jump height in a loaded jump squat test performed in a Smith machine. Key pointsVertical jump height in the loaded jump squat can be estimated with acceptable precision from the maximum bar velocity recorded by a linear velocity transducer.The relationship between the point at which bar acceleration is less than -9.81 m·s(-2) and the real take-off is affected by the velocity of movement.Mean propulsive velocity recorded by a linear velocity transducer does not appear to be optimal to monitor ballistic exercise performance.

  1. Estimating tropical vertical motion profile shapes from satellite observations

    Back, L. E.; Handlos, Z.

    2013-12-01

    The vertical structure of tropical deep convection strongly influences interactions with larger scale circulations and climate. This research focuses on investigating this vertical structure and its relationship with mesoscale tropical weather states. We test the hypothesis that vertical motion shape varies in association with weather state type. We estimate mean state vertical motion profile shapes for six tropical weather states defined using cloud top pressure and optical depth properties from the International Satellite Cloud Climatology Project. The relationship between vertical motion and the dry static energy budget are utilized to set up a regression analysis that empirically determines two modes of variability in vertical motion from reanalysis data. We use these empirically determined modes, this relationship and surface convergence to estimate vertical motion profile shape from observations of satellite retrievals of rainfall and surface convergence. We find that vertical motion profile shapes vary systematically between different tropical weather states. The "isolated systems" regime exhibits a more ''bottom-heavy'' profile shape compared to the convective/thick cirrus and vigorous deep convective regimes, with maximum upward vertical motion occurring in the lower troposphere rather than the middle to upper troposphere. The variability we observe with our method does not coincide with that expected based on conventional ideas about how stratiform rain fraction and vertical motion are related.

The approach is motivated by the difficulty in incorporating behavioral aspects of carbon transport into large scale carbon budgets of the world's oceans. The results show......Through diel vertical migration (DVM), zooplankton add an active transport to the otherwise passive sinking of detrital material that constitutes the biological pump. This active transport has proven difficult to quantify. We present a model that estimates both the temporal and depth characteristic...... that despite their lower abundance, large zooplankton (length circa 1–2 mm) migrate deeper and transport approximately twice as much carbon as do the smaller zooplankton (length circa 0.2–0.3 mm).

    NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this 180-degree view of the rover's surroundings during the 1,798th Martian day, or sol, of Opportunity's surface mission (Feb. 13, 2009). North is on top. This view is presented as a vertical projection with geometric seam correction. The rover had driven 111 meters (364 feet) southward on the preceding sol. Tracks from that drive recede northward in this view. For scale, the distance between the parallel wheel tracks is about 1 meter (about 40 inches). The terrain in this portion of Mars' Meridiani Planum region includes dark-toned sand ripples and lighter-toned bedrock.

    Located at the center of the neck and the pharyngeal column and, thanks to its attachments, tied to the base of the skull, to the mandible, to the tongue, to the larynx, and to the scapular belt, the hyoid bone is intimately related to an extensive tendino-muscular complex. From this strategic position, the hyoid bone participates in all functional and nutritional activities of the oro-facial complex. Heavily involved in the physiology of the pharyngeal column, it appears to enjoy a remarkable stability in relation to its surrounding structures as it participates in the critical process of vertical ontogenetic development. Deceptively simple in its shape and location it is anything but. While it would be easy to scorn it as a vestigial organ of little importance, the hyoid bone is actually an ancient witness of the evolution of the first human vertebrae and a vestige of the 2nd and 3rd brachial arches. Like a toy buffeted by powerful groups of muscles and tendons, the hyoid bone occupies a crossroads position where it is solicited by many vital functions, the most critical of which is respiration. Its functional behavior seems to have evolved considerably over the course of phylogeny. By piecing together the conceptions of many authors, we can conclude that the similarities--and, later, the differences--existing between the human fetus and those of other primates, and, then between young children and young primates, are related to an essentially different status quo, which modifies the delicate equilibrium of the pharyngeal region. In metamorphosing from a sagittal equilibrium to one that is vertical, this very status quo maintains an open respiratory airway during each time frame, continuously permitting the articulation and modulation of sounds, particularly during the vertical period. The hyoid bone is unpaired, in a mid-line position, symmetrical, and located just below the mandible with which it shares, to an astonishing extent, certain morphological

    Experiments at the DIII-D tokamak demonstrate a non-monotonic relationship between measured scrape-off layer (SOL) currents and vertical displacement event (VDE) rates with SOL currents becoming largely n=1 dominant as plasma is displaced by the plasma control system (PCS) at faster rates. The DIII-D PCS is used to displace the magnetic axis 10x slower than the intrinsic growth time of similar instabilities in lower single-null plasmas. Low order (n control is disabled. Previous inquiry shows VDE asymmetry characterized by SOL current fraction and geometric parameters of tokamak plasmas. We note that, of plasmas displaced by the PCS, short displacement time scales near the limit of the PCS temporal control appear to result in larger n=1/n=2 asymmetries.

    If light new physics with lepton-flavor-violating couplings exists, the prime discovery channel might not be ℓ →ℓ‧ γ but rather ℓ →ℓ‧ X, where the new boson X could be an axion, majoron, familon or Z‧ gauge boson. The most conservative bound then comes from ℓ →ℓ‧ + inv , but if the on-shell X can decay back into leptons or photons, displaced-vertex searches could give much better limits. We show that only a narrow region in parameter space allows for displaced vertices in muon decays, μ → eX , X → γγ , ee, whereas tauon decays can have much more interesting signatures.

    Health care providers may vertically integrate not only to facilitate coordination of care, but also for strategic reasons that may not be in patients' best interests. Optimal Medicare reimbursement policy depends upon the extent to which each of these explanations is correct. To investigate, we compare the consequences of the 1997 adoption of prospective payment for skilled nursing facilities (SNF PPS) in geographic areas with high versus low levels of hospital/SNF integration. We find that SNF PPS decreased spending more in high integration areas, with no measurable consequences for patient health outcomes. Our findings suggest that integrated providers should face higher-powered reimbursement incentives, i.e., less cost-sharing. More generally, we conclude that purchasers of health services (and other services subject to agency problems) should consider the organizational form of their suppliers when choosing a reimbursement mechanism.

    2013-01-01

    Multispectral imaging is a powerful tool that extends the capabilities of the human eye. However, multispectral imaging systems generally are expensive and bulky, and multiple exposures are needed. Here, we report the demonstration of a compact multispectral imaging system that uses vertical silicon nanowires to realize a filter array. Multiple filter functions covering visible to near-infrared (NIR) wavelengths are simultaneously defined in a single lithography step using a single material (silicon). Nanowires are then etched and embedded into polydimethylsiloxane (PDMS), thereby realizing a device with eight filter functions. By attaching it to a monochrome silicon image sensor, we successfully realize an all-silicon multispectral imaging system. We demonstrate visible and NIR imaging. We show that the latter is highly sensitive to vegetation and furthermore enables imaging through objects opaque to the eye.

  9. Premixed flame propagation in vertical tubes

    Kazakov, Kirill A

    2015-01-01

    Analytical treatment of premixed flame propagation in vertical tubes with smooth walls is given. Using the on-shell flame description, equations describing quasi-steady flame with a small but finite front thickness are obtained and solved numerically. It is found that near the limits of inflammability, solutions describing upward flame propagation come in pairs having close propagation speeds, and that the effect of gravity is to reverse the burnt gas velocity profile generated by the flame. On the basis of these results, a theory of partial flame propagation driven by the gravitational field is developed. A complete explanation is given of the intricate observed behavior of limit flames, including dependence of the inflammability range on the size of the combustion domain, the large distances of partial flame propagation, and the progression of flame extinction. The role of the finite front-thickness effects is discussed in detail. Also, various mechanisms governing flame acceleration in smooth tubes are ide...

Nei's genetic distance varied from D = 0.0638 between PL and YA to D = 0.0174 between IT and YA. These results indicate the existence of genetic differentiation and that, possibly, the Guaíra Falls isolated the populations reproductively. They also suggest the possibility of different spawning areas, partially avoiding the genetic homogenization of the IT and PL populations.

    Since electron microscopy (EM) first appeared in the 1930s, it has held centre stage as the primary tool for the exploration of biological structure. Yet, with the recent developments of light microscopy techniques that overcome the limitations imposed by the diffraction boundary, the question arises as to whether the importance of EM in on the wane. This Commentary describes some of the pioneering studies that have shaped our understanding of cell structure. These include the development of cryo-EM techniques that have given researchers the ability to capture images of native structures and at the molecular level. It also describes how a number of recent developments significantly increase the ability of EM to visualise biological systems across a range of length scales, and in 3D, ensuring that EM will remain at the forefront of biology research for the foreseeable future.

    We review recent work to determine the strange quark mass m{sub s} as well as the proposal to determine vertical bar V{sub us} vertical bar using hadronic {tau} decay data. The recent update of the strange spectral function by OPAL and their moments of the invariant mass distribution are employed. Our results are vertical bar V{sub us} vertical bar=0.2208+/-0.0034 and m{sub s}(2GeV)=81+/-22 MeV. Our result is already competitive to the standard extraction of vertical bar V{sub us} vertical bar from K{sub e3} decays and to the new proposals to determine it. The error on vertical bar V{sub us} vertical bar is dominated by experiment and will be eventually much improved by the B-factories hadronic {tau} data. Ultimately, a simultaneous fit to both m{sub s} and vertical bar V{sub us} vertical bar to a set of moments of the hadronic {tau} decays invariant mass distribution will provide one of the most accurate determinations of these Standard Model parameters.

    A facile method was demonstrated to decorate aerosol Ag nanoparticles onto vertical graphene surfaces using a mini-arc plasma reactor. The vertical graphene was directly grown on a sensor electrode using a plasma-enhanced chemical vapor deposition (PECVD) method. The aerosol Ag nanoparticles were synthesized by a simple vapor condensation process using a mini-arc plasma source. Then, the nanoparticles were assembled on the surface of vertical graphene through the assistance of an electric field. Based on our observation, nonagglomerated Ag nanoparticles formed in the gas phase and were assembled onto vertical graphene sheets. Nanohybrids of Ag nanoparticle-decorated vertical graphene were characterized for ammonia gas detection at room temperature. The vertical graphene served as the conductance channel, and the conductance change upon exposure to ammonia was used as the sensing signal. The sensing results show that Ag nanoparticles significantly improve the sensitivity, response time, and recovery time of the sensor.

    Vertical heat transport by evaporation and condensation is a key process in transferring energy from the surface of the Earth to the atmosphere. Although this process has been studied for a long time, thermodynamic constraints on this process and on the vertical structures of the atmosphere are still poorly understood and quantified. In this work, we use a simple 1D vertical energy-entropy climate model to investigate this issue. Especially, we explore the roles of the entropy-rated constraints in determining vertical heat transport and atmospheric vertical structures. The sensitivities of the vertical distributions of atmospheric temperature, the energy and entropy fluxes to the variation of solar radiation are also discussed.

    In 2009, Ministry of Education, Culture, Sports, Science and Technology(MEXT) started the survey system development for Hydrothermal deposit. We proposed the Vertical Cable Seismic (VCS), the reflection seismic survey with vertical cable above seabottom. VCS has the following advantages for hydrothermal deposit survey. (1) VCS is an efficient high-resolution 3D seismic survey in limited area. (2) It achieves high-resolution image because the sensors are closely located to the target. (3) It avoids the coupling problems between sensor and seabottom that cause serious damage of seismic data quality. (4) Because of autonomous recording system on sea floor, various types of marine source are applicable with VCS such as sea-surface source (GI gun etc.) , deep-towed or ocean bottom source. Our first experiment of 2D/3D VCS surveys has been carried out in Lake Biwa, JAPAN, in November 2009. The 2D VCS data processing follows the walk-away VSP, including wave field separation and depth migration. Seismic Interferometry technique is also applied. The results give much clearer image than the conventional surface seismic. Prestack depth migration is applied to 3D data to obtain good quality 3D depth volume. Seismic Interferometry technique is applied to obtain the high resolution image in the very shallow zone. Based on the feasibility study, we have developed the autonomous recording VCS system and carried out the trial experiment in actual ocean at the water depth of about 400m to establish the procedures of deployment/recovery and to examine the VC position or fluctuation at seabottom. The result shows that the VC position is estimated with sufficient accuracy and very little fluctuation is observed. Institute of Industrial Science, the University of Tokyo took the research cruise NT11-02 on JAMSTEC R/V Natsushima in February, 2011.

    The VCS (Vertical Cable Seismic) is one of the reflection seismic methods. It uses hydrophone arrays vertically moored from the seafloor to record acoustic waves generated by surface, deep-towed or ocean bottom sources. Analyzing the reflections from the sub-seabed, we could look into the subsurface structure. Because VCS is an efficient high-resolution 3D seismic survey method for a spatially-bounded area, we proposed the method for the hydrothermal deposit survey tool development program that the Ministry of Education, Culture, Sports, Science and Technology (MEXT) started in 2009. We are now developing a VCS system, including not only data acquisition hardware but data processing and analysis technique. We carried out several VCS surveys combining with surface towed source, deep towed source and ocean bottom source. The water depths of the survey are from 100m up to 2100m. The target of the survey includes not only hydrothermal deposit but oil and gas exploration. Through these experiments, our VCS data acquisition system has been completed. But the data processing techniques are still on the way. One of the most critical issues is the positioning in the water. The uncertainty in the positions of the source and of the hydrophones in water degraded the quality of subsurface image. GPS navigation system are available on sea surface, but in case of deep-towed source or ocean bottom source, the accuracy of shot position with SSBL/USBL is not sufficient for the very high-resolution imaging. We have developed another approach to determine the positions in water using the travel time data from the source to VCS hydrophones. In the data acquisition stage, we estimate the position of VCS location with slant ranging method from the sea surface. The deep-towed source or ocean bottom source is estimated by SSBL/USBL. The water velocity profile is measured by XCTD. After the data acquisition, we pick the first break times of the VCS recorded data. The estimated positions of

    Se evaluó la eficacia biológica de ocho aislamientos de <em>Trichoderma spp. em> provenientes de suelos de Colombia para el control de los agentes causales de volcamiento, <em> Sclerotium rolfsiiem> y <em> Rhizoctonia solaniem>, bajo condiciones <em> in vitroem> y de invernadero. Los análisis <em> in vitroem> mostraron la capacidad antagónica de todos los aislamientos evaluados. En condiciones de invernadero, cuatro aislamientos fueron altamente eficaces contra <em> S. rolfsiiem> en plantas de fríjol en semillero (>90% de reducción de la enfermedad y dos aislamientos fueron eficaces contra <em> R. solaniem> en plantas de algodón en semillero (58 y 61% de reducción de la enfermedad. El análisis UP-PCR y DS-PCR permitió determinar tres grupos de aislamientos; dentro de estas asociaciones formadas no se encontró ninguna relación evidente entre la posición en el dendrograma y la actividad antagónica, pero sí permitió separar las especies de <em> Trichodermaem> por grupos, e incluso encontrar diferencias dentro de aislamientos de una misma especie. Los resultados muestran que el comportamiento micoparasítico de los aislamientos de <em> Trichoderma spp. em> varía según el hongo fitopatógeno, evidenciando una amplia especificidad del antagonista por su sustrato, es decir por el hongo atacado; por lo tanto es necesario realizar cuidadosas selecciones del aislamiento de <em> Trichodermaem> que se utilice en programas de control de fitopatógenos.

    Full Text Available Heat shock proteins (HSPs play various stress-protective roles in plants. In this study, three <em>HSP> genes were isolated from a suppression subtractive hybridization (SSH cDNA library of <em>Ginkgo bilobaem> leaves treated with cold stress. Based on the molecular weight, the three genes were designated <em>GbHSP16.8em>, <em>GbHSP17em> and <em>GbHSP70em>. The full length of the three genes were predicted to encode three polypeptide chains containing 149 amino acids (Aa, 152 Aa, and 657 Aa, and their corresponding molecular weights were predicted as follows: 16.67 kDa, 17.39 kDa, and 71.81 kDa respectively. The three genes exhibited distinctive expression patterns in different organs or development stages. <em>GbHSP16.8em> and <em>GbHSP70em> showed high expression levels in leaves and a low level in gynoecia, <em>GbHSP17em> showed a higher transcription in stamens and lower level in fruit. This result indicates that <em>GbHSP16.8em> and <em>GbHSP70 em>may play important roles in <em>Ginkgo> leaf development and photosynthesis, and <em>GbHSP17em> may play a positive role in pollen maturation. All three <em>GbHSPs> were up-regulated under cold stress, whereas extreme heat stress only caused up-regulation of <em>GbHSP70em>, UV-B treatment resulted in up-regulation of <em>GbHSP16.8em> and <em>GbHSP17em>, wounding treatment resulted in up-regulation of <em>GbHSP16.8em> and <em>GbHSP70em>, and abscisic acid (ABA treatment caused up-regulation of <em>GbHSP70em> primarily.

    2013-08-01

    This study aims to review the main methods used to improve vertical jump performance (VJP). Although many training routines have been proposed, these can be grouped into four main categories: plyometric training (PT), weight training (WT), whole body vibration training (VT) and electromyostimulation training (ET). PT enhances muscular force, the rate of force development (RFD), muscular power, muscle contraction velocity, cross-sectional area (CSA), muscle stiffness allowing greater storage and release of elastic energy. WT improve muscular force, velocity, power output, and RFD during jumping on a force plate, muscle hypertrophy and neural adaptations. One of the most effective methods to improve VJP is the combination of PT with WT, which takes advantage of the enhancement of maximal dynamic force through WT and the positive effects of PT on speed and force of muscle contraction through its specific effect on type II fibers. Some authors have found an increase in VJP with the use of VT while other did not see such an effect. However, it remains unknown by which mechanisms VT could enhance VJP. ET has been shown to elicit muscle hypertrophy. The VJP may be improved when ET is applied concomitantly with PT or practice of sports. In summary, scientific evidence suggests that the best way to improve VJP is through the combination of PT with WT. Further research is needed to establish if better results are possible by more complex strategies.

    With vertical integration, registrars and medical students attend the same educational workshops. It is not known whether these learners have similar or different learning styles related to their level of education within the medical training schema. This study aims to collect information about learning styles with a view to changing teaching strategies. If a significant difference is demonstrated this will impact on required approaches to teaching. The VARK learning inventory questionnaire was administered to 36 general practice registrars and 20 medical students. The learning styles were compared as individuals and then related to their level of education within the medical training schema. Students had a greater preference for multimodal learning compared with registrars (62.5 per cent versus 33.3 per cent, respectively). More than half of the registrars preferred uni or bimodal learning modalities, compared with one-third of the medical students. The present workshop format based on visual and aural material will not match the learning needs of most learners. This small study has shown that the majority of medical students and registrars could have their learning preferences better met by the addition of written material to the workshop series. Surprisingly, a significantly larger number of medical students than registrars appeared to be broadly multimodal in their learning style, and this warrants further research. © 2013 John Wiley & Sons Ltd.

  15. Vertical landscraping, a big regionalism for Dubai.

    Wilson, Matthew

    2010-01-01

    Dubai's ecologic and economic complications are exacerbated by six years of accelerated expansion, a fixed top-down approach to urbanism and the construction of iconic single-phase mega-projects. With recent construction delays, project cancellations and growing landscape issues, Dubai's tower typologies have been unresponsive to changing environmental, socio-cultural and economic patterns (BBC, 2009; Gillet, 2009; Lewis, 2009). In this essay, a theory of "Big Regionalism" guides an argument for an economically and ecologically linked tower typology called the Condenser. This phased "box-to-tower" typology is part of a greater Landscape Urbanist strategy called Vertical Landscraping. Within this strategy, the Condenser's role is to densify the city, facilitating the creation of ecologic voids that order the urban region. Delineating "Big Regional" principles, the Condenser provides a time-based, global-local urban growth approach that weaves Bigness into a series of urban-regional, economic and ecological relationships, builds upon the environmental performance of the city's regional architecture and planning, promotes a continuity of Dubai's urban history, and responds to its landscape issues while condensing development. These speculations permit consideration of the overlooked opportunities embedded within Dubai's mega-projects and their long-term impact on the urban morphology.

    Tamppari, L. K.; Lemmon, M. T.

    2011-01-01

    Phoenix results, combined with coordinated observations from the Mars Reconnaissance Orbiter of the Phoenix lander site, indicate that the water vapor is nonuniform (i.e., not well mixed) up to a calculated cloud condensation level. It is important to understand the mixing profile of water vapor because (a) the assumption of a well-mixed atmosphere up to a cloud condensation level is common in retrievals of column water abundances which are in turn used to understand the seasonal and interannual behavior of water, (b) there is a long history of observations and modeling that conclude both that water vapor is and is not well-mixed, and some studies indicate that the water vapor vertical mixing profile may, in fact, change with season and location, (c) the water vapor in the lowest part of the atmosphere is the reservoir that can exchange with the regolith and higher amounts may have an impact on the surface chemistry, and (d) greater water vapor abundances close to the surface may enhance surface exchange thereby reducing regional transport, which in turn has implications to the net transport of water vapor over seasonal and annual timescales.

The readout board hosts a bank of FPGA’s, one per VIPIC-L to allow processing of up to 0.7 Tbps of raw data produced by the camera.

  18. Potential of Vertical Hydroponic Agriculture in Mexico

    2017-01-01

    Full Text Available In 2050, Mexico’s population will reach 150 million people, about 80% of whom will likely live in urban centers. This increase in population will necessitate increased food production in the country. The lands classified as drylands in Mexico occupy approximately 101.5 million hectares, or just over half the territory, limiting the potential for agricultural expansion. In addition to the problem of arid conditions in Mexico, there are conditions in other parts of the country related to low to very low water availability, resulting in pressure on the water resources in almost two-thirds of the country. Currently, agriculture uses 77% of the water withdrawn, primarily for food production. This sector contributes 12% of the total greenhouse gas emission (GHG production in the country. Given the conditions of pressure on water and land resources in Mexico and the need to reduce the carbon footprint, vertical farming technology could offer the possibility for sustainable food production in the urban areas of the country in the coming years.

  19. Vertical barriers with increased sorption capacities

    Bradl, H.B. [Bilfinger + Berger Bauaktiengesellschaft, Mannheim (Germany)

    1997-12-31

    Vertical barriers are commonly used for the containment of contaminated areas. Due to the very small permeability of the barrier material which is usually in the order of magnitude of 10-10 m/s or less the advective contaminant transport can be more or less neglected. Nevertheless, there will always be a diffusive contaminant transport through the barrier which is caused by the concentration gradient. Investigations have been made to increase the sorption capacity of the barrier material by adding substances such as organoclays, zeolites, inorganic oxides and fly ashes. The contaminants taken into account where heavy metals (Pb) and for organic contaminants Toluole and Phenantrene. The paper presents results of model calculations and experiments. As a result, barrier materials can be designed {open_quotes}tailor-made{close_quotes} depending on the individual contaminant range of each site (e.g. landfills, gasworks etc.). The parameters relevant for construction such as rheological properties, compressive strength and permeability are not affected by the addition of the sorbents.

    Re-planning of LTCS TVAC testing and supporting RTA (Receiver Telescope Assembly) Test Plan and Procedure document preparation. The Laser Thermal Control System (LTCS) is designed to maintain the lasers onboard Advanced Topographic Laser Altimeter System (ATLAS) at their operational temperatures. In order to verify the functionality of the LTCS, a thermal balance test of the thermal hardware was performed. During the first cold start of the LTCS, the Loop Heat Pipe (LHP) was unable to control the laser mass simulators temperature. The control heaters were fully on and the loop temperature remained well below the desired setpoint. Thermal analysis of the loop did not show these results. This unpredicted behavior of the LTCS was brought up to a panel of LHP experts. Based on the testing and a review of all the data, there were multiple diagnostic performed in order to narrow down the cause. The prevailing theory is that gravity is causing oscillating flow within the loop, which artificially increased the control power needs. This resulted in a replan of the LTCS test flow and the addition of a GSE heater to allow vertical operation.

    The International Young Physicists' Tournament (IYPT) is a worldwide, annual competition for high school students. This paper is adapted from the winning solution to Problem 14, Magnetic Spring, as presented in the final round of the 23rd IYPT in Vienna, Austria. Two magnets were arranged on top of each other on a common axis. One was fixed, while the other could move vertically. Various parameters of interest were investigated, including the effective gravitational acceleration, the strength, size, mass and geometry of the magnets, and damping of the oscillations. Despite its simplicity, this setup yielded a number of interesting and unexpected relations. The first stage of the investigation was concerned only with the undamped oscillations of small amplitudes, and the period of small amplitude oscillations was found to be dependent only on the eighth root of important magnet properties such as its strength and mass. The second stage sought to investigate more general oscillations. A numerical model which took into account magnet size, magnet geometry and damping effects was developed to model the general oscillations. Air resistance and friction were found to be significant sources of damping, while eddy currents were negligible.

  2. Functionalization of vertically aligned carbon nanotubes

    Directory of Open Access Journals (Sweden)

    Eloise Van Hooijdonk

    2013-02-01

    Full Text Available This review focuses and summarizes recent studies on the functionalization of carbon nanotubes oriented perpendicularly to their substrate, so-called vertically aligned carbon nanotubes (VA-CNTs. The intrinsic properties of individual nanotubes make the VA-CNTs ideal candidates for integration in a wide range of devices, and many potential applications have been envisaged. These applications can benefit from the unidirectional alignment of the nanotubes, the large surface area, the high carbon purity, the outstanding electrical conductivity, and the uniformly long length. However, practical uses of VA-CNTs are limited by their surface characteristics, which must be often modified in order to meet the specificity of each particular application. The proposed approaches are based on the chemical modifications of the surface by functionalization (grafting of functional chemical groups, decoration with metal particles or wrapping of polymers to bring new properties or to improve the interactions between the VA-CNTs and their environment while maintaining the alignment of CNTs.

  3. Maximum height and minimum time vertical jumping.

    Domire, Zachary J; Challis, John H

    2015-08-20

    The performance criterion in maximum vertical jumping has typically been assumed to simply raise the center of mass as high as possible. In many sporting activities minimizing movement time during the jump is likely also critical to successful performance. The purpose of this study was to examine maximum height jumps performed while minimizing jump time. A direct dynamics model was used to examine squat jump performance, with dual performance criteria: maximize jump height and minimize jump time. The muscle model had activation dynamics, force-length, force-velocity properties, and a series of elastic component representing the tendon. The simulations were run in two modes. In Mode 1 the model was placed in a fixed initial position. In Mode 2 the simulation model selected the initial squat configuration as well as the sequence of muscle activations. The inclusion of time as a factor in Mode 1 simulations resulted in a small decrease in jump height and moderate time savings. The improvement in time was mostly accomplished by taking off from a less extended position. In Mode 2 simulations, more substantial time savings could be achieved by beginning the jump in a more upright posture. However, when time was weighted more heavily in these simulations, there was a more substantial reduction in jump height. Future work is needed to examine the implications for countermovement jumping and to examine the possibility of minimizing movement time as part of the control scheme even when the task is to jump maximally.

    This is the first report of an outbreak of Theileria lestoquardi abortion and stillbirth in a mob of 450 ewes in July 2012, during which, approximately 35 late-term ewes lost their fetuses over a 5-day period. A dead ewe and her aborted fetus were transported to the Ahvaz Veterinary Hospital for the diagnostic evaluation. The microbial cultures from the ewe vaginal discharges and fetal abomasal contents and the liver were negative. The blood films of the ewe and her fetus contained Theileria piroplasms and the impression smears from ewe liver and fetal spleen were positive for Theileria Koch blue bodies. The DNA was extracted from the liver and spleen of ewe and her fetus, respectively, and analyzed by polymerase chain reaction (PCR) using specific primers derived from the nucleotide sequences of 18S ribosomal DNA (rDNA) gene of T. lestoquardi. A single fragment of 428-bp fragment was amplified. The PCR product was directly sequenced and the alignment of the sequence with similar sequences in GenBank(®) showed 100% identities with 18S rDNA gene of T. lestoquardi. The present study is the first report of the T. lestoquardi vertical transmission that could be related to the abortion. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available INTRODUCTION: Currently in orthodontic diagnosis, besides the lateral cephalometric analysis which evaluates the anteroposterior and vertical direction, the frontal analysis may be added, leading us to another important dimension in space: the transverse dimension. OBJECTIVE: Few longitudinal samples with the frontal radiograph were published, so this cephalometric study was designed to correlate the transversal and vertical measures by Ricketts-Faltin frontal analysis into two radiographic times. METHODS: The sample consisted of 45 Brazilian children, 25 girls and 20 boys, all presenting mixed dentition, with balanced facial aesthetics and no previous orthodontic/orthopedic treatment. The initial average age (T1 was 7.7 years and the final (T2 13.3 years. The measurements evaluated were: FTD, MxTD, NTD, LITD, MdTD (transversal, OVD and TVD (vertical. RESULTS: All transversal measures were positively correlated with a medium or high correlation with each other and the vertical measurements; only LITD presented a low correlation with these measurements. CONCLUSION: It was concluded that the face has interdependent regions and that this feature remains with growth.INTRODUÇÃO: atualmente no diagnóstico ortodôntico, além da análise cefalométrica lateral - que avalia os sentidos anteroposterior e vertical -, deve-se acrescentar a análise no sentido frontal, a qual propicia outra dimensão importante no espaço, a transversal.

Métodos Estudo descritivo e analítico que usou as bases de dados de laboratórios da Rede Nacional de Laboratórios de CD4 e Carga Viral de DST/Aids do Ministério da Saúde. As grávidas com HIV-1 foram selecionadas em uma pesquisa ativa de informações clínicas e dados obstétricos e neonatais em seus prontuários médicos entre 1998-2011. Resultados Foram analisadas 102 grávidas entre 1998 e 2004 e 251 entre 2005-2011, no total 353 crianças nascidas de grávidas com HIV-1. Observou-se que a transmissão vertical foi de 11,8% entre 1998 e 2004 e de 3,2% entre 2005-2011 (p < 0,001. O maior uso de medicamentos antirretrovirais (p = 0,02, a redução na carga viral (p < 0,001 e o tempo de ruptura de membranas menor do que quatro horas (p < 0,001 foram associados à redução nos fatores de transmissão vertical quando os dois períodos são comparados. Conclusão Observou-se uma redução na taxa de transmissão vertical nos últimos anos. De acordo com as variáveis estudadas, sugere-se que os fatores de risco de transmissão vertical de HIV-1 foram ausência de terapia antirretroviral, alta carga viral das grávidas e tempo de ruptura maior do que quatro horas.

    Operating experimental devices have provided key inputs to the design process for ITER axisymmetric control. In particular, experiments have quantified controllability and robustness requirements in the presence of realistic noise and disturbance environments, which are difficult or impossible to characterize with modeling and simulation alone. This kind of information is particularly critical for ITER vertical control, which poses some of the highest demands on poloidal field system performance, since the consequences of loss of vertical control can be very severe. The present work describes results of multi-machine studies performed under a joint ITPA experiment on fundamental vertical control performance and controllability limits. We present experimental results from Alcator C-Mod, DIII-D, NSTX, TCV, and JET, along with analysis of these data to provide vertical control performance guidance to ITER. Useful metrics to quantify this control performance include the stability margin and maximum controllable vertical displacement. Theoretical analysis of the maximum controllable vertical displacement suggests effective approaches to improving performance in terms of this metric, with implications for ITER design modifications. Typical levels of noise in the vertical position measurement which can challenge the vertical control loop are assessed and analyzed.

    Ooi, P. K.; Ibrahim, K.

    2008-05-01

    Vertical MOSFET has been introduced in the last few decades. As planar devices become smaller and smaller, vertical MOS transistor is one of the solutions for surpassing the short channel effects and pattern transfer. Thus, it is a promising approach to achieve channel lengths between 100 nm and 25 nm. In this work, we simulate sub-100 nm single channel length vertical silicon MOSFET. The simulations are done with using ATHENA, DEVEDIT and ATLAS from SILVACO International. Input and output electrical characteristics of the vertical MOS transistors are investigated. The short channel effects of the vertical MOSFETs are explored. Due to the structure is not symmetry, source at top and bottom is also considered. The results also compared with experimental results from other researcher.

  17. Impact of Vertical Wind Shear on Tropical Cyclone Rainfall

    Science.gov (United States)

    Cecil, Dan; Marchok, Tim

    2014-01-01

    While tropical cyclone rainfall has a large axisymmetric component, previous observational and theoretical studies have shown that environmental vertical wind shear leads to an asymmetric component of the vertical motion and precipitation fields. Composites consistently depict a precipitation enhancement downshear and also cyclonically downwind from the downshear direction. For consistence with much of the literature and with Northern Hemisphere observations, this is subsequently referred to as "Downshear-Left". Stronger shear magnitudes are associated with greater amplitude precipitation asymmetries. Recent work has reinforced the prior findings, and explored details of the response of the precipitation and kinematic fields to environmental vertical wind shear. Much of this research has focused on tropical cyclones away from land, to limit the influence of other processes that might distort the signal related to vertical wind shear. Recent evidence does suggest vertical wind shear can also play a major role in precipitation asymmetries during and after landfall.

    Full Text Available INTRODUÇÃO: A instabilidade funcional (IF é a complicação mais comum após o entorse de tornozelo; acomete até 52% dos atletas com história de entorse. O entorse de tornozelo é uma das lesões esportivas mais comuns, inclusive no voleibol, em que 90% dos entorses de tornozelo ocorrem durante a aterrissagem, após o movimento de bloqueio. A IF é definida por queixas de falseios e entorses recorrentes, sem que haja evidências clínicas de lesão ligamentar, sendo extremamente prejudicial para a prática do voleibol, pois interfere na realização dos fundamentos envolvidos na modalidade. OBJETIVOS: Comparar os padrões temporais e de magnitude da atividade eletromiográfica dos músculos tibial anterior (TA, fibular longo (FL e gastrocnêmio lateral (GL durante a aterrissagem do salto vertical após a execução da habilidade do bloqueio do voleibol entre jogadores com e sem IF de tornozelo. MÉTODOS: Foi adquirida a atividade EMG do tibial anterior, do fibular longo e do gastrocnêmio lateral em 21 atletas com IF (GI e em 19 atletas controle (GC - idade média de 20 ± 4 anos. Os envoltórios lineares foram calculados para cada um dos grupos no período de tempo entre 200ms antes e 200ms após o instante do impacto, determinados por meio da componente vertical da FRS. A magnitude e o instante do pico máximo de cada um dos músculos também foram determinados matematicamente. Os grupos foram comparados por meio do teste t (α = 0,05. RESULTADOS: O grupo com instabilidade apresentou instante de pico do TA mais tardio ± (GC = -107,4 ± 29,6ms; GI = -134,0 ± 26,0ms e FL (GC = -11,0 ± 55,9ms; GI = -41,7 ± 49,8ms e menor pico de TA (GC = 68,5 ± 17,2%; GI = 81,2 ± 28,8% e FL (GC = 72,9 ± 27,3%; GI = 59,1 ± 16,0%, CONCLUSÕES: Os resultados mostram um padrão de alteração mais tardio e com menor magnitude nos músculos de atletas com IF que podem predispô-los à condição de instabilidade, mesmo na ausência de lesão anat

  20. On the vertical extent of atmospheric feedbacks

    2001-03-01

    This study addresses the question: what vertical regions contribute the most to water vapor, surface temperature, lapse rate and cloud fraction feedback strengths in a general circulation model? Multi-level offline radiation perturbation calculations are used to diagnose the feedback contribution from each model level. As a first step, to locate regions of maximum radiative sensitivity to climate changes, the top of atmosphere radiative impact for each feedback is explored for each process by means of idealized parameter perturbations on top of a control (1 x CO{sub 2}) model climate. As a second step, the actual feedbacks themselves are calculated using the changes modelled from a 2 x CO{sub 2} experiment. The impact of clouds on water vapor and lapse rate feedbacks is also isolated using 'clear sky' calculations. Considering the idealized changes, it is found that the radiative sensitivity to water vapor changes is a maximum in the tropical lower troposphere. The sensitivity to temperature changes has both upper and lower tropospheric maxima. The sensitivity to idealized cloud changes is positive (warming) for upper level cloud increases but negative (cooling) for lower level increases, due to competing long and shortwave effects. Considering the actual feedbacks, it is found that water vapor feedback is a maximum in the tropical upper troposphere, due to the large relative increases in specific humidity which occur there. The actual lapse rate feedback changes sign with latitude and is a maximum (negative) again in the tropical upper troposphere. Cloud feedbacks reflect the general decrease in low- to mid-level low-latitude cloud, with an increase in the very highest cloud. This produces a net positive (negative) shortwave (longwave) cloud feedback. The role of clouds in the strength of the water vapor and lapse rate feedbacks is also discussed. (orig.)
