Topping time, yield and quality of Florence fennel and basil seed
No full textThe effects of inflorescence removal time (topping) relative to stage of plant growth in Florence fennel (Foeniculum vulgare Mill. var. azoricum Thell.) and basil (Ocimum basilicum L.) were examined.
In the fennel during the first year 5 topping treatments were made: 1) control; 2) topping at boot stage; 3) topping at emergence of primary umbel (PU) with removal of the PU+first order, 4) topping at emergence of PU with removal of the PU only; 5) topping at beginning flowering of PU. In the second year topping treatments happened at boot stage, at initial and full flowering of PU.
In the basil 8 treatments were planned:1) control; 2) topping the main stem at appearance of the spike; 3) as treatment 2 by topping all the stems; 4) treatment 2, 7 days later; 5) treatment 3, 7 days later; 6) treatment 2 topped 14 days later; 7) topping apex and 2 expanded leaves below of all stems; 8) topping apex and 3 expanded leaves below of all stems
Topping treatments did not influence the yield and yield component of fennel and basil.
For the fennel in the first year germination percent was higher for the "seed" coming from PU and when the topping occurred at beginning of the flowering. "Seeds" from PU reached earlier predetermined germination percent and showed a higher germination value. In the second year, germination percent decreased when topping happened at boot stage and at beginning of the flowering, while the time to reach a pre-determinate germination percent was shorter when elimination of the PU occurred at full flowering.
In the basil higher and lower germination percent resulted by topping according to treatment n. 7 and n. 6 respectively. Longer time to reach ninety-five percent of the final germination was observed when plants were topped as treatment n. 2

Ejector-Assisted Liquid Metal Topping Cycles
No full textDirect fired coal power stations exhibit a comparatively poor performance since they cannot be operated in a combined cycle. A liquid metal topping cycle could dramatically improve their overall conversion efficiency. The high temperature required poses demanding technical problems both in the primary heat exchanger and in the turbine. The present paper discusses the possibility of alleviating the turbine-related problems through the use of an ejector which transfers the energy produced in a metal vapour topping cycle to a helium-vapour mixture at much lower temperature and pressure. Ejector performance is analysed both from a mechanical and from a thermodynamic point of view. Three typical alkali metal fluids are examined: sodium, potassium and cesium. The efficiency of the energy transfer from vapour to helium significantly increases with the metal molecular weight and attains optimum values of around 90 per cent. Turbine inlet temperature reduction due to the ejector action is about 500 K. Important gains are also the reduction in turbine inlet pressure and expansion ratio. After the energy transfer to helium and the turbine expansion, metal vapour and inert gas are separated by vapour condensation at a decreasing temperature. Such cooling represents the main thermodynamic loss in the process. At a maximum temperature of 1500 K and a condensation temperature for the reference vapour cycle of 950 K, computed efficiencies of the ejector-assisted topping cycle are in the range 17–19 per cent, as against pure vapour cycle efficiencies in the range 24–26 per cent. The strong cooling of the mixture needed to separate the liquid metal implies a significant increase in heat consumption which can be mitigated by means of an internal heat regeneration, which improves cycle efficiency to 19–22 per cent. With reference to a standard steam bottoming cycle, and including electrical, mechanical and boiler losses, plant efficiencies of around 50 per cent seem achievable
Study of LH2-fueled topping cycle engine for aircraft propulsion
No full textAn analytical investigation was made of a topping cycle aircraft engine system which uses a cryogenic fuel. This system consists of a main turboshaft engine which is mechanically coupled (by cross-shafting) to a topping loop which augments the shaft power output of the system. The thermodynamic performance of the topping cycle engine was analyzed and compared with that of a reference (conventional-type) turboshaft engine. For the cycle operating conditions selected, the performance of the topping cycle engine in terms of brake specific fuel consumption (bsfc) was determined to be about 12 percent better than that of the reference turboshaft engine. Engine weights were estimated for both the topping cycle engine and the reference turboshaft engine. These estimates were based on a common shaft power output for each engine. Results indicate that the weight of the topping cycle engine is comparable to that of the reference turboshaft engine
ANÁLISE DE COR INSTRUMENTAL E SENSORIAL DE TOPPING DE AZEITONA
No full textOs topping são caracterizados pela existência de frutos inteiros ou em pedaços padronizados, imersos em um líquido viscoso, na qual sua textura deve ser firme para que somente escorra lentamente sobre o alimento durante o seu consumo. A estrutura do topping está fundamentada na ação de hidrocolóides e de acidulantes que mantém a estrutura estável, redução do pH, proporcionando estabilidade química e preservação das características sensoriais do produto como a cor, por exemplo. Neste contexto, o presente trabalho objetivou avaliar a influência do emprego associado de diferentes concentrações de hidrocolóides na cor instrumental e sensorial de amostras de topping de azeitona. No desenvolvimento das formulações do topping de azeitona, suco, água potável, ácido cítrico e concentrações diferenciadas de guar (G) e xantana (X) (topping1: 0,75% G + 0,25% X), (topping 2: 0,50% G + 0,50% X), (topping 3: 0,25% G + 0,75% X) foram homogeneizados em agitador magnético com aquecimento. A determinação instrumental da cor foi efetuada em colorímetro (sistema CIE L*a*b*), onde: L* indica luminosidade; a* e b* representam as coordenadas de cromaticidade. A partir dos parâmetros mensurados foram determinados o ângulo Hue (H°) e Croma (C*). As análises foram realizadas em triplicata e os resultados foram tratados por Análise de Variância e Teste de Tukey (95%). Na análise da cor sensorialfoi empregado o teste de aceitabilidade, com 70 julgadores não treinados da UNIPAMPA Bagé. Neste teste os julgadores expressaram seu grau de gostar ou desgostar do produto em relação ao atributo cor através de uma escala estruturada de 9 pontos, com os extremos gostei muitíssimo e desgostei muitíssimo. Observou-se que houve diferença significativa (
Leonard J. Arrington: A Historian\u27s Life
No full textGary Topping, a professor at Salt Lake Community College, has previously published a number of books and articles on Utah environmental history and historians who have lived in Utah. In some ways, Topping\u27s article on Robert Dwyer and his book on historians Bernard DeVoto, Juanita Brooks, Wallace Stegner, Dale Morgan, and Fawn Brodie can be considered precursors to this book.
In other ways, this book is also somewhat of a new foray; unlike most of the other historians Topping has treated, Leonard Arrington was neither a non-Mormon nor a lapsed Mormon. He remained an active Latter-day Saint throughout his life. Arrington served in numerous ecclesiastical positions, including as a counselor in a stake presidency and Church Historian--the only person whom the First Presidency has called to the position who was not also a General Authority. President Gordon B. Hinckley asked Arrington\u27s widow, Harriet Horne Arrington, for permission to speak at his funeral, which she gladly gave.
In spite of the title, Topping\u27s book is a selective intellectual biography rather than a complete Historian\u27s Life. In the preface, Topping clearly states, I have confined my attention to those works that strike me as most important and also from which I can most efficiently and persuasively make the points I wish to make. This procedure results in a book that touches on Arrington\u27s early life and education but focuses almost entirely on his books and articles on Mormon topics, especially those about the nineteenth century. With the exception of Arrington\u27s biography of Brigham Young, the biographies Topping reviews are those commissioned by families, and all of them consider Latter-day Saints who lived in the nineteenth and early twentieth centuries. While Topping examines works such as Building the City of God, The Mormon Experience, and Mormons and Their Historians, his book does not consider the extensive body of Arrington\u27s work, often written in collaboration with others, on twentieth-century Utah and Western economic and social history
The prevention of sucker growth of tobacco after topping
No full textExperiments conducted overseas and elsewhere in Australia have shown that the application of mineral oils to the cut surface of the tobacco stem after topping (removal of the flower head) have reduced the amount of sucker growth of tobacco plants. Previous experience in Western Australia has shown that the most appropriate time for topping of tobacco crops has been after the first leaf has been harvested. This operation has the effect of putting more body and width into the tip leaves, which, without topping, tend to be narrow and comparatively light in weight. With late planted crops, however, crops are generally left untopped, since the topping operation tends to retard the ripening of leaf by several weeks, although, after this period, the leaves ripen more rapidly and evenly
