    Full Text Available Objetivou-se avaliar nutricionalmente a grama-estrela (Cynodon nlemfuensis cv. Africana utilizada sob pastejo rotacionado por vacas leiteiras. Dez vacas mestiças foram manejadas em 2 ha de grama-estrela e divididas em 11 piquetes/ha. O período de pastejo foi de três dias e os 30 subseqüentes foram destinados à recuperação da pastagem. Durante o período experimental, os animais foram ordenhados duas vezes ao dia e receberam suplementação com 2 kg de concentrado. Amostras representativas do pasto ingeridas (extrusa foram colhidas para determinação de sua composição nutricional. O consumo de matéria seca (MS pelos animais foi estimado utilizando-se cromo e a MS indigestível como indicadores externo e interno. O desempenho individual das vacas foi avaliado pela produção de leite diária e pela pesagem dos animais. A dinâmica da matéria alimentar foi estimada com base nas técnicas in vitro gravimétricas, de produção cumulativa de gases da fermentação microbiana e da estimativa da cinética de passagem das fases sólida e líquida. A quantidade de energia líquida total (ELt, em MJ/dia, atendeu à demanda energética exigida pelos animais. Os valores de proteína metabolizável (PM preditos corresponderam ao suprimento de 91% da PM exigida por esses animais. As predições das exigências em macrominerais atenderam apenas 75% do Ca exigido, mas atenderam às exigências dos demais macrominerais. A grama-estrela atende à demanda energética nutricional de mantença e produção de 11,7 kg de leite por dia. Nas circunstâncias estudadas, é necessário suplementar nutrientes que complementem a PM e Ca não atendidos completamente.

    Full Text Available Objetivou-se avaliar o desempenho e a qualidade do leite produzido por vacas da raça Holandesa no terço final da lactação, alimentadas com silagens de grama estrela com aplicação de inoculante ou uréia em relação à silagem de milho. Foram avaliadas silagens de grama estrela com aplicação de aditivo enzimo-bacteriano na dosagem de 80 g deinoculante/tonelada, uréia na dosagem de 7 kg t-1 e silagem de milho. Para avaliação do desempenho produtivo e digestibilidade foram utilizadas seis vacas da raça Holandesas com peso médio de 480 kg distribuídas em delineamento (duplo quadrado latino (3 x 3. Asdigestibilidades da MS, PB e FDN foram maiores para a silagem de milho. O fornecimento de silagens de grama estrela com aditivo e com uréia não interferiu na produção e qualidade do leite, mostrando-se como alternativa para sistemas de produção animal com base emvolumosos conservados mediante a análise econômica da substituição da silagem de milho.The study aimed to evaluate animal performance and quality of milk from Holstein cows during the final third period of lactation fed stargrass silages supplied with inoculant or urea in relation to corn silage. Stargrass silages with enzymatic-bacterial inoculant (80 g of additive/ton of silage, urea supply (7 kg t-1 and corn silage were evaluated. Six Holstein cows with an average body weight of 480 kg were allocated in a double Latin square design (3 x 3. Corn silagepresented the highest values of DM, CP and NDF digestibility when compared to stargrass silages. Supplying Holstein cows with stargrass silages with additive and urea did not promote any effect on production and milk quality. Thus, it can be an alternative in animalproduction systems based on conserved roughage, depending on economical analysis for the replacement of corn silage.

    Full Text Available Este trabalho foi realizado com o objetivo de investigar o comportamento das enzimas pectina metilesterase (PME e β-galactosidase (β-Gal durante o amadurecimento do mamão cv.'Golden'. Mamões com 15% de cor amarela foram estocados em câmara de refrigeração a 20ºC e 85-95 % UR, por um período de 11 dias. Durante este período de estocagem, foi determinada a cor da casca, firmeza e pH da polpa dos frutos, bem como a atividade das enzimas PME e β-Gal. A atividade da PME, observada ao longo do amadurecimento do mamão, indicou que esta enzima participou do processo de hidrólise da parede celular, principalmente no início do amadurecimento dos frutos. Já a atividade da β-Gal aumentou, de maneira não gradual, do primeiro dia até o final do armazenamento, quando alcançou seu valor máximo. Uma redução drástica na firmeza e no pH da polpa ocorreu nos três primeiros dias de armazenamento. Neste período, os frutos apresentaram coloração com valores do ângulo hue próximos de 80, a qual corresponde a uma coloração amarela. Verificou-se que a PME atua de modo efetivo no amadurecimento do mamão, mas a redução precoce em sua atividade indica que a β-Gal tem também um papel fundamental na rápida perda de firmeza pelo mamão cv. Golden.

Foram realizadas a determinação da cor externa dos frutos e análises das características químicas de teor de sólidos solúveis, pH, acidez titulável, açúcares redutores, 'ratio' e ácido ascórbico de frutos semi-maduros e maduros. Os resultados obtidos permitiram concluir que os frutos semimaduros apresentaram maior acidez total, menor teor de sólidos solúveis e menor concentração de açúcares; no entanto, estes frutos apresentaram maiores teores de vitamina C, expressa em ácido ascórbico. Portanto, quando se buscam altos índices de vitamina C, os frutos devem ser colhidos num estádio de maturação menos avançado, com coloração alaranjada. O estudo demonstrou também que a cv Olivier produz frutos com características adequadas tanto para o mercado in natura quanto para a indústria, apresentando boa coloração e características químicas dentro dos padrões para esta fruta.

Com objetivo de determinar a época na qual ocorre a indução e evocação floral, cortes longitudinais de gemas apicais e axilares, corados com pironina Y-methylgreen foram efetuados em períodos regulares de maio a agosto. Através das mudanças no formato da gema, principalmente diâmetro, que aumentou com a indução, foi possível determinar a época do ano na qual gemas vegetativas são induzidas a florescerem. Foram detectadas variações nos diâmetros das gemas no período de início da morfogênese floral (meados até o final de julho. A medição do diâmetro das gemas mostra-se um procedimento eficiente para acompanhar os fenômenos decorrentes da indução, evocação e morfogênese florais. Gemas vegetativas apresentam diâmetro médio de 100µm, com túnica composta por três camadas, de formato cônico, recobrindo o corpo, ao passo que a reprodutiva é mais achatada, após a iniciação do primeiro primórdio de sépala, exibindo diâmetro médio de 200µm.

O objetivo desse trabalho foi avaliar o comportamento da cultura da melancieira em sistemas orgânicos sobre os componentes de produção e a caracterização química dos frutos. O experimento foi conduzido na Estação Experimental Agroecológica do CCHA, Campus IV da UEPB, em Catolé do Rocha. Foram avaliados os efeitos de 3 fontes de matéria orgânica e 5 dosagens de biofertilizante nos componentes de produção de melancieira. O delineamento experimental utilizado foi em blocos ao acaso, num esquema fatorial 5x3, com 4 repetições. A água para suprimento da irrigação teve como fonte um aqüífero, poço amazonas próximo ao local do experimento e o método de irrigação foi por gotejamento. As variáveis analisadas foram: Número de frutos por planta; Comprimento do fruto; Perímetro do fruto; Número de sementes por fruto; Sólidos Solúveis totais (ºBrix, (pH dos frutos, Produção por planta e Produtividade. A adubação orgânica com húmus, esterco bovino, esterco caprino e biofertilizante influenciam positivamente os componentes de produção de melancia. O esterco caprino pode substituir o esterco bovino e o húmus na adubação orgânica da melancia. A produtividade registrada para as plantas adubadas organicamente independentemente da fonte é compatível ao representado em cultivo convencional.

    Full Text Available A uva Isabel, originária do Sul dos Estados Unidos, é uma das principais cultivares de Vitis labrusca. Atualmente é a cultivar mais difundida na Serra Gaúcha, representando aproximadamente 45% de toda a uva produzida nessa região. Além da elaboração de vinho tinto comum, a Isabel é utilizada para elaboração de vinho rosado e suco e comercializada como uva de mesa. O objetivo do presente trabalho foi determinar as características agronômicas e enológicas da uva Isabel, para elaboração de vinho tinto comum. Para isso, avaliou-se a maturação da uva e realizaram-se estudos para caracterizar o cacho, o mosto e o vinho tinto, nas safras de 1988 a 1994. Os resultados obtidos evidenciaram que a uva Isabel tem cacho pequeno, solto, formado por bagas e sementes grandes. O mosto apresenta cor rosada pouco intensa, tem bom teor de açúcar e baixo nível de ácido málico e acidez total. O vinho tem cor vermelha viva; o aroma é intenso e com acentuada tipicidade varietal; a análise sensorial evidencia que geralmente falta ao vinho equilíbrio e maciez.

    Full Text Available O Brasil é considerado o maior produtor de citros e o maior exportador de suco de laranja. Doenças de pós-colheita representam uma grande perda para a citricultura, sendo que para a exportação de frutos são rígidas as exigências com relação a isenção de resíduos químicos nos mesmos. Patógenos de importância em pós-colheita de citros incluem o Penicillium digitatum, agente causal do bolor-verde e o Colletotrichum gloeosporioides, agente causal da antracnose. Dada a importância econômica que representam estas doenças dos frutos cítricos, tanto em termos de comprometimento da qualidade e dificuldade de controle, a busca de alternativas adicionais que possam viabilizar a capacidade produtiva e garantir a obtenção de frutos com excelentes padrões de qualidade torna-se imprescindível. Portanto, estudou-se os efeitos dos extratos aquosos do flavedo de Citrus aurantifolia var. Tahiti, Lentinula edodes, Agaricus subrufescens (syn. Agaricus brasiliensis, albedo de Citrus sinensis var. Valência e do ácido jasmônico no controle póscolheita do bolor verde e da antracnose e na indução de resistência em frutos de laranjeira Valência (Citrus sinensis. Foi possível observar que o extrato aquoso do flavedo (C. aurantifolia apresentou efeito inibitório sobre os patógenos, quando tratados em pós-colheita, em função da redução dos sintomas e esporulação. Porém, os extratos de albedo (C. sinensis, L. edodes, A. subrufescens e o ácido jasmônico não apresentaram efeitos sobre P. digitatum e C. gloeosporioides.

As avaliações foram realizadas após nove meses de armazenamento, no momento da abertura das câmaras e após sete dias de exposição a 25ºC. Somente os frutos mantidos em 800m.L-1 de etileno durante o período de conservação em AC foram influenciados pelo etileno, apresentando maior respiração e síntese de etileno, menor firmeza de polpa e cor de fundo da epiderme mais amarela do que aqueles armazenados com 0,25 ou 20m.L-1 de etileno na atmosfera da câmara. A maçã 'Fuji' apresentou baixa sensibilidade a altas concentrações de etileno durante o armazenamento em AC, não se justificando a sua absorção em câmaras comerciais.The experiment was carried out aiming to evaluate the effect of ethylene concentrations on the quality and occurrence of physiological disorders on Fuji apples stored in controlled atmosphere (CA with 1kPa O2 / 0,2kPa CO2 at 0.5ºC. The treatments applied were: 0.25; 20; and 800m.L-1 ethylene. The evaluations were accomplished after nine months of storage, at the opening of the chambers and after seven days in shelf life (25ºC. Only the fruits kept at 800m.L-1 ethylene during storage period were influenced by the ethylene, showing higher respiration and ethylene biosynthesis, lower firmness and more yellow background color of the peel than those stored with 0.25 or 20m.L-1. Fuji apples presented low sensibility to high ethylene concentrations during storage in AC, therefore absorption is not recomended in commercial storage rooms.

Durante o período experimental (09/94 a 12/95, ocorreu uma precipitação efetiva de 671 mm/ano. Houve efeito positivo das lâminas crescentes de irrigação sobre a diferenciação floral natural e antecipação no período de colheita do fruto, o que resultou no encurtamento do ciclo da planta, sem que se observasse prejuízo ao peso médio do fruto, das parcelas submetidas às maiores lâminas d'água. Nestas, mais de 70% dos frutos foram colhidos com uma antecipação de 22 dias em relação ao final da colheita. As maiores lâminas de irrigação permitiram igualmente uma distribuição mais eqüitativa da colheita, no período em que ela ocorreu.

    Food irradiation is one of the most promising treatments that can be utilized for fruits disinfestation and extension of shelf life. The authors studied the influence of 0,5 kGy of Gamma irradiation on the soluble carbohydrates composition of papaya (Carica papaya L. cv. Solo) fruit, and on sucrose metabolizing enzymes: sucrose synthase (SS), sucrose-phosphate synthase, acid and neutral invertases activities, during ripening. The results demonstrated that ethylene production, total soluble sugars, sucrose content, and sucrose-phosphate synthase and invertases activities were affected by irradiation, but not respiration, glucose and fructose content, and SS activity.

    Full Text Available A irradiação de alimentos é um tratamento pós-colheita bastante promissor, capaz de atuar tanto na desinfestação como no aumento da vida útil de frutos. O mamão é um fruto com curta vida pós-colheita, levando de 6 a 12 dias para atingir a senescência. Além disto, a infestação por larvas de mosca diminui sensivelmente o seu potencial de exportação. O objetivo deste trabalho foi verificar a ação de uma dose de 0,5 kGy de irradiação gama, normalmente utilizada para desinfestação e aumento de vida útil dos frutos, sobre o comportamento dos carboidratos solúveis durante o amadurecimento do mamão (Carica papaya L. cv. Solo, e sobre as enzimas relacionadas ao metabolismo da sacarose: sacarose sintase (SS, sacarose-fosfato sintase (SPS e invertases ácida e neutra. Os resultados demonstraram que a irradiação não exerce efeito sobre o teor de glicose e frutose, ou sobre a respiração e atividade da SS.

Os tratamentos foram arranjados segundo fatorial 2 x 2 x 5, em blocos casualizados com três repetições, e consistiram de duas formas de aplicação de fósforo (localizada no fundo do sulco e distribuída no sulco com incorporação, dois espaçamentos entre linhas de plantio (0,5 e 1,0 m e cinco doses de fósforo (0, 30, 60, 100 e 150 kg/ha de P e a 0, 60, 120, 200 e 300 kg/ha, para as aplicações localizada e distribuída, respectivamente. Foram efetuadas sete colheitas (cortes das plantas nos sulcos (linhas centrais da parcela, correspondente a 2 m². Após pesagem da forragem colhida, amostras foram retiradas para determinação dos teores de MS. Amostras de solo também foram colhidas sobre as linhas de plantas após cada corte, para determinação dos teores de fósforo disponível pelo extrator Mehlich-1. Após cada corte, foi feita adubação em cobertura com nitrogênio e potássio (67 kg/ha de N e K2O utilizando-se sulfato de amônio e cloreto de potássio. A adubação fosfatada apresentou efeitos residuais sobre a produção de MS do capim-elefante durante dois anos após o estabelecimento da forrageira. Maiores produções foram verificadas no espaçamento de 0,5 m entre linhas de plantio. A forma de aplicação do fertilizante não influenciou o rendimento de MS. Os níveis críticos de fósforo no solo mostraram-se estáveis com a sucessão de cortes, apresentando maiores valores para o espaçamento de 1,0 m e na forma distribuída e incorporada no sulco para os dois espaçamentos.The experiment was conducted over two years to evaluate the residual effect of phosphate fertilizer application on the DM yield and the soil P critical levels for maintenance of elephantgrass (Pennisetum purpureum Schum. cv

    Full Text Available O experimento foi realizado no município de Aparecida do Rio Doce-GO, no sudoeste Goiano, durante os anos de 2007 e 2008, visando a caracterizar a produção da videira 'Niágara Rosada', em diferentes épocas de poda: (1 09-07-07; (2 28-09-07; (3 03-03-08 e (4 19-04-08. Variáveis associadas à produção por planta, avaliação de cachos e bagas, folhas remanescentes na colheita, posição de brotos na gema e quantidade de cachos/broto, pH, sólidos solúveis (SS, acidez titulável (AT e relação SS/AT foram analisadas nas produções obtidas nas quatro épocas de poda. A maior massa de cachos foi encontrada nas podas de julho e de abril. As podas realizadas em março e abril permitiram maior número de cachos e maior produtividade. A poda de setembro apresentou maior comprimento, largura e massa de bagas. A qualidade dos frutos foi semelhante entre as safras, mostrando apenas diferenças significativas para pH, AT e para a relação SS/AT nas quatro épocas. A época de poda 3 apresentou o menor valor de folhas remanescentes em relação às demais (6,15 folhas, não sendo considerado como grande desfolha nem causando quedas de produtividade. Para a avaliação da posição do broto na gema, a maior média foi observada na época de poda 1, sendo que as gemas de maior frequência de emissão de ramos com frutos foram aquelas onde se aplicou a cianamida hidrogenada (3ª a 6ª gema, indispensável na estimulação das brotações em videiras. Então, conclui-se que a videira Niágara Rosada pode ser podada nas quatro épocas do ano estudadas no Sudoeste Goiano, já que as avaliações dos cachos e bagas mostraram-se satisfatórias em relação a outras regiões, e as precipitações não afetaram a qualidade final dos frutos em nenhum dos períodos.

O número de gemas e o número de brotações foram avaliados com intervalo semanal, num total de quatro avaliações, e, na última avaliação, considerou-se a altura da brotação, bem como foi determinada a taxa de multiplicação. O maior número de gemas foi obtido com 2miM de BAP e, na ausência de AIB, enquanto o maior número de brotações foi atingido, até a terceira semana de cultivo, com 2 e 4miM de BAP. Para altura das brotações, tanto na ausência como no nível de 1miM de AIB, o aumento nas concentrações de BAP resultou na diminuição do comprimento das brotações linearmente. Observou-se, de modo geral, com o aumento dos níveis de BAP, para todas as doses de AIB, uma redução na altura das brotações. A concentração de 1miM de AIB associado com BAP influenciou negativamente a taxa de multiplicação, até a concentração de 5,9miM de BAP.

Verificou-se que a associação do tratamento hidrotérmico à aplicação de cloreto de cálcio é viável, e que existe uma correlação positiva entre o Ca aplicado e a quantidade deste elemento na casca, porém com pouca penetração para a polpa do fruto, o que demonstra que o Ca age positivamente na diminuição dos sintomas da antracnose. Pelo contraste apresentado na aparência externa dos frutos, a aplicação de cloreto de cálcio a 4% mostrou melhores resultados, porém sem garantir a qualidade final exigida para a exportação dos frutos. A aplicação de cloreto de cálcio não se mostrou efetiva no aumento do período de conservação dos frutos.The aim of this work was to study the effects of the application of calcium chloride associated with hydrothermal treatment on post-harvest preservation of mango fruit (Mangifera indica L.. The Ca absorption by mango peel and flesh was investigated using the same conditions usually employed for the fruit exportation to the american market. It was verified that the association of heat treatment to Ca application was viable. There was a positive correlation between the amount of Ca applied and the amount of this element presented in the peel, although low penetration toward the flesh was observed. It was demonstrated that Ca reduces anthracnose symptoms. It was also verified, by observing the external appearance of the fruits, that the best results were obtained when 4% of calcium chloride was used, although such concentration did not guarantee the required quality for the fruit exportation. The calcium chloride application was not effective to increase the shelf-life of the fruits.

    Neste trabalho, quatro épocas de plantio (março, abril, maio e junho, 1994 combinadas respectivamente com um, dois, três e quatro meses de armazenamento do alho-planta, a temperaturas entre 5 e 10°C, foram comparadas com as mesmas épocas de plantio de alho-planta armazenado em condições ambientais, na cultivar Cateto Roxo, em Goiânia, Goiás. Usou-se o delineamento de blocos casualizados com três repetições e parcelas subdivididas. A produção de bulbos curados e limpos, tanto dos bulbilhos frigorificados quanto dos não frigorificados, diminuiu com o tempo de armazenamento, em regressão linear. A frigorificação do alho-planta por apenas um mês e plantado em março reduziu a produção em 50% em relação ao não frigorificado, e a combinação de quatro meses de frigorificação com o plantio em junho anulou a produção. A freqüência do número de plantas com bulbilhos aéreos mostrou tendência à redução de março a junho. Concluiu-se que a frigorificação do alho-planta da cultivar Cateto Roxo diminui severamente a produção sem qualquer vantagem econômica.

    The high quality garlic cultivars in Brazil were grown only in the southern part of the country because of its higher latitude and cool climate during the growing season. These cultivars yield well also in lower latitude regions when cold storaged planting stock is used. Concerning traditional cultivars in the tropics, however, there is a lack of information on the effect of cold storage. Cateto Roxo is well adapted to the Brazilian tropics from the middle-west (Goiás up to the north-east (Piauí. On this cultivar, four planting dates (March, April, May and June, 1994 combined

O objetivo deste trabalho foi averiguar as diferenças morfoanatômicas da epiderme foliar na tentativa de diferenciar as plantas de 'Prata-anã' em relação aos seus variantes somaclonais. A análise por microscopia eletrônica de varredura mostrou uma diferença significativa entre o diâmetro polar dos estômatos da 'Prata-anã' não variante e suas variantes, ambas em condições in vitro, observando-se que o mesmo não ocorre para as plantas in vivo. O número médio de estômatos é menor nas plantas variantes somaclonais, porém sem diferenças significativas a não ser para a planta PIII. A descamação de cera é evidente somente nas plantas variantes de ambos os materiais (in vitro e in vivo. Conclui-se que os caracteres morfoanatômicos da epiderme foliar, como densidade estomática, diâmetro estomático polar e a uniformidade da cera atuam como marcadores morfológicos para caracterizar as plantas micropropagadas de 'Prata-anã' em relação aos seus variantes somaclonais para a característica gigantismo.Somaclonal variation corresponds to the emergence of abnormal plants during the process of multiplication in vitro, mainly related to stature, in the case the gigantism.

    Full Text Available O presente trabalho teve por objetivo identificar os estádios da cultura de feijão que apresentam a menor sensibilidade ao estresse de água no solo, nos quais a irrigação pode ser omitida sem um significativo decréscimo na evapotranspiração, para melhor definir práticas de irrigação em situação de água escassa. O experimento foi realizado em um solo franco arenoso (Typic Haplustoll, em Tumbaco-Pichincha, Equador, entre julho e novembro de 1994, região caracterizada por um clima temperado e seco (temperatura média anual de 16ºC, umidade relativa média do ar 74% e chuva de 123 mm durante o peláodo do experimento. Sete regimes de irrigação foram utilizados, incluindo irrigação ótima durante todo o ciclo, irrigação deficiente durante todo o ciclo, irrigação tradicional da região, deficiência lúdrica no período vegetativo, na floração e formação de vagens, no enchimento de vagens e na maturidade. As parcelas experimentais foram de 33,6 m2 (8 linhas de 7 metros de comprimento, distantes entre si 0,6 m com uma população de 120.000 plantas/ha. Os tratamentos de irrigação foram aplicados depois da germinação uniforme das sementes e estabelecimento da cultura. A umidade do solo foi monitorada com sonda de nêutrons, até a profundidade de 50 em, 24 horas antes e depois de cada irrigação. A evapotranspiração atual da cultura foi estimada pela técnica do balanço hídrico. Da análise dos resultados obtidos, concluiu-se que a deficiência de água no solo, durante a fase de enchimento da vagem, afetou a produtividade do feijoeiro. Nesta fase a eficiência de uso de água pela planta (Ec = 0,46 kg/m3 foi a mais baixa. Deficiência de irrigação no estádio vegetativo não reduziu a produtividade, permitindo uma economia de água de 30%.

A aplicação foi feita em maio, quando as frutas estavam com coloração verde-amarelada, e as coletas para avaliação feitas a cada 30 dias, até o mês de novembro. Foram feitas 7 coletas no total. As variáveis estudadas foram coloração da epiderme, espessura da casca, pH do suco, acidez total titulável (ATT, teor de sólidos solúveis totais (SST, relação SST/ATT, índice tecnológico e rendimento de suco. Os resultados obtidos não permitiram concluir que o ácido giberélico tenha influência sobre as características fisico-químicas do suco, tais como pH, rendimento, SST, AT, Ratio e índice tecnológico. A espessura da casca também não foi influenciada pelo AG3. No entanto, o ácido giberélico reteve a coloração verde da casca, segundo um gradiente no que diz respeito à concentração, no sentido de que ao aumentá-la, manteve por mais tempo a coloração verde das frutas. Este comportamento foi observado em maior ou menor escala, em todos os pHs da solução. O pH=3 da calda de aplicação foi o que reteve por mais tempo a coloração verde nas frutas, indicando assim que o ácido giberélico foi mais absorvido neste pH, do que nos demais. O pH normal (4,5 reteve a coloração verde das frutas por mais tempo que o pH=6, indicando assim que pHs mais ácidos favorecem a absorção do ácido giberélico pelas plantas. Foi observado também que o ácido giberélico atrasou o fenômeno do reverdecimento, o qual ocorre quando as temperaturas se tornam mais altas.The objective of this work was to study the effect of gibberellic acid on "Valência" orange fruits, when applied at various concentrations, under

The relationship between moisture content and water activity provides useful information for the processing and storage of this waste item. The aim of this study was to determine the mechanism of water sorption enthalpy-entropy of orange seeds (C. sinensis cv. Brazilians according to the moisture content. Therefore, desorption isotherms were determined at five different temperature (30, 40, 50, 60, and 70 ºC under a wide range of moisture content (0.005-0.057 kg kg-1 d.b. and water activity (0.02-0.756. Theoretical and empirical models were used for modeling the desorption isotherms. An analytical solution of the Clausius-Clapeyron equation was proposed to compute the isosteric heat of sorption, the differential entropy, and Gibbs free energy using the Oswin model when the effect of temperature on the hygroscopic equilibrium was considered.As sementes de laranja são resíduos promissores da agroindústria com um alto potencial de aplicação na produção de óleo vegetal.

    Cotesia vestalis (Haliday) is an endoparasitoid of Plutella xylostella (L.) larvae and injects a polydnavirus (CvBV) into its host during oviposition. In this report we describe the characterization of a gene (CvBV805) and its products. CvBV805 is located on the segment S8 of CvBV genome; it has a size of 909 bp and encodes a predicted protein of 125 amino acids. This protein contains an ankyrin repeat domain with a high degree of similarity with IκB-like genes. Gene transcripts were detected in extracts of the host as early as 2 h post-parasitization (p.p.) and continued to be detected through 24 h. Tissue-specific expression patterns showed that CvBV805 might be involved in early host immunosuppression. CvBV805 was detected in parasitized hosts at 12 h p.p. and in rBac-eGFP-CvBV805-infected Tn-5B1-4 cells at 72 h.p.i. by using western blots analysis. The size of the protein expressed in the host hemocytes and infected Tn-5B1-4 cells was 17 kDa and 56 kDa (including eGFP), respectively, which nearly corresponded with the predicted molecular weight (14.31 kDa) of CvBV805, suggesting that the protein did not undergo extensive post-translational modification. The protein was confirmed to be present within the nuclear region in hemocytes of the parasitized P. xylostella larvae at 48 h p.p. using confocal laser scanning microscopy

    Full Text Available The coat protein (CP gene of the potato virus Y strain "o" (PVY O was introduced into potato, cultivar Achat, via Agrobacterium tumefaciens-mediated transformation. Sixty three putative transgenic lines were challenged against the Brazilian strains PVY-OBR and PVY-NBR. An extremely resistant phenotype, against the two strains, was observed in one line, denominated 1P. No symptoms or positive ELISA results were observed in 16 challenged plants from this line. Another clone, named as 63P, showed a lower level of resistance. Southern blot analysis showed five copies of the CP gene in the extremely resistant line and at least three copies in the other resistant line. The stability of the integrated transgenes in the extreme resistant line was examined during several in vitro multiplications over a period of three years, with no modification in the Southern pattern was observed. The stability of the transgenes, the absence of primary infections and the relatively broad spectrum of resistance suggest that the extremely resistant line obtained in this work can be useful for agricultural purposes.O gene da capa protéica (CP do Potato virus Y estirpe "o", foi introduzido em batata cultivar Achat, via Agrobacterium tumefaciens.

Os tratamentos consistiram da combinação de sete regimes de irrigação, incluindo irrigação ótima durante todo o ciclo, irrigação deficiente durante todo o ciclo, irrigação tradicional da região, deficiência hídrica no período vegetativo, na floração e formação de vagens, no enchimento de vagens e na maturidade; e de dois níveis de adubação nitrogenada (20 kg N/ha e 80 kg N/ha. Os quatorze tratamentos resultantes foram arranjados e analisados num esquema de parcelas sub-divididas com quatro repetições. O tamanho da parcela experimental foi de 33,6 m2 (8 linhas de 7 metros de comprimento, distantes entre si 0,6 m com uma população de 120.000 plantas/ha. O nitrogênio fixado do ar pelo feijoeiro foi calculado pelo método de diluição isotópica do 15N, no tratamento com adubação de 20 kg N/ha. A solução marcada foi de sulfato de amônio, com abundância de 5% de átomos de 15N. Como planta-controle, foi utilizado o trigo, semeado no sulco central. Da análise dos resultados obtidos, concluiu-se que: A deficiência de água no solo, durante a fase vegetativa, não afetou a eficiência de uso de nitrogênio, a fixação biológica do nitrogênio, nem a produção de sementes, permitindo uma economia de água de 30%. A deficiência de água durante a floração e enchimento de vagens, afetou drasticamente a fixação biológica do nitrogênio, que comparativamente ao controle, foi reduzida 2,2 vezes.To identify specific growth stages of the common bean crop at which

    Full Text Available Japansche citroen (JC rootstock is still the main choice for producing citrus seeds for its high availability and compatibility. Other rootstocks have been used in the production, yet they produce unsatisfying results. Based on the theory, there is an alternative to use rootstock as interstock in order to stimulate the growth of scion. The objective of this reseach is to understand the effect of interstock on the growth of Mandarin cv. Batu 55, Tangerine cv. Pontianak and Lime cv. Nimas. This research was conducted in the screen house of Tlekung Experimental Field of Indonesian Citrus and Subtropical Fruits Research Institute (ICSFRI in Batu-East Java, located on 950 m asl, from January to April 2016. This research was arranged in a CRD design with 4 replications and 24 interstock-scion combination treatments. The interstocks used in this study were Carizzo citrange, Citrumello, Poncirus trifoliata, Volkameriana, Rough lemon, Troyer citrange, Kanci and control (JC combined with 3 scions namely Mandarin cv. Batu 55, Tangerine cv. Pontianak and Lime cv. Nimas propagated by grafting. The result showed the percentage of successful grafting ranged between 37.5% to 100%, while the percentage of the shoot formed on grafted plants was 75%-100%. The use of Poncirus trifoliata as interstock has stimulated fastest bud break on Tangerine cv. Pontianak in just 24.75 days while the Troyer citrange has stimulated better shoot growth in Lime cv. Nimas, resulted to the highest shoot around 52.20 cm which was significantly different from other treatments. Meanwhile, Carizzo citrange has been found to have some influences to the plant diameter and the number of leave of Lime cv. Nimas but showed insignificant effect on the growth of its own diameter. The use of interstock showed that it can be used to promote the growth of scion which usually has slow growth when it is directly grafted on the rootstock.

    Full Text Available fMRI studies showed that acupuncture could induce hemodynamic changes in brain networks. Many of these studies focused on whether specific acupoints could activate specific brain regions and were often limited to manual acupuncture at acupoints on the limbs. In this fMRI study, we investigated acupuncture's modulation effects on brain functional networks by electroacupuncture (EA at acupoints on the midline of abdomen. Acupoints Guanyuan (CV4 and Zhongwan (CV12 were stimulated in 21 healthy volunteers. The needling sensations, brain activation, and functional connectivity were studied. We found that the limbic-prefrontal functional network was deactivated by EA at CV4 and CV12. More importantly, the local functional connectivity was significantly changed during EA stimulation, and the change persisted during the period after the stimulation. Although minor differences existed, both acupoints similarly modulated the limbic-prefrontal functional network, which is overlapped with the functional circuits associated with emotional and cognitive regulation.

    The cooling and Ventilation (CV) group has emphasised the need to redefine its organisational structure at the end of 98. The main objective of this operation was to ensure the CV group to be more competitive and efficient through the growing tasks of the LHC projects. The main evolution given to this reorganisation is that the new structure is more project oriented and then operates on three distinct axes: Design, Work and Operation. Process control project management requires a complete and early interaction and participation of all the actors involved. This procedure to be efficient and constructive must be considered and performed not only during the design stage but along the project planning phases and must go beyond the completion work including the process control operation activity. The paper explains the present project management for process control. It describes the present constraints and gives suggestions to a different approach to these projects to improve performances and efficiency of a contr...

    2009-01-01

    Net tidal torque by the secondary on a misaligned accretion disk, like the net tidal torque by the Moon and the Sun on the equatorial bulge of the spinning and tilted Earth, is suggested by others to be a source to retrograde precession in non-magnetic, accreting cataclysmic variable (CV) dwarf novae (DN) systems that show negative superhumps in their light curves. We investigate this idea in this work. We generate a generic theoretical expression for retrograde precession in spinning disks that are misaligned with the orbital plane. Our generic theoretical expression matches that which describes the retrograde precession of Earths' equinoxes. By making appropriate assumptions, we reduce our generic theoretical expression to those generated by others, or to those used by others, to describe retrograde precession in protostellar, protoplanetary, X-ray binary, non-magnetic CV DN, quasar, and black hole systems. We find that spinning, tilted CV DN systems cannot be described by a precessing ring or by a precessing rigid disk. We find that differential rotation and effects on the disk by the accretion stream must be addressed. Our analysis indicates that the best description of a retrogradely precessing spinning, tilted, CV DN accretion disk is a differentially rotating, tilted disk with an attached rotating, tilted ring located near the innermost disk annuli. In agreement with the observations and numerical simulations by others, we find that our numerically simulated CV DN accretion disks retrogradely precess as a unit. Our final, reduced expression for retrograde precession agrees well with our numerical simulation results and with selective observational systems that seem to have main-sequence secondaries. Our results suggest that a major source to retrograde precession is tidal torques like that by the Moon and the Sun on the Earth. In addition, these tidal torques should be common to a variety of systems where one member is spinning and tilted, regardless if

The beef burger samples were stored at-25° C for 14 months and subjected to sensory analysis (color, aroma, flavor, and texture at the beginning of the experiment and the measurement of color (parameters L a*, b* and h* every two months. The addition of the extracts did not promote changes in the sensory attributes of the beef burgers at time zero of storage. A tendency to decrease a* values and increase of the h* values of the samples of frozen beef burgers occurred over the period of storage. Samples added with ethyl acetate fraction (0.5 and 0.7% and the oily extract of rosemary showed higher a* values than the other samples throughout the storage period and lower h* values than the standard sample at the end of the period evaluated. This indicates that the addition of ethyl acetate fraction and rosemary extract contributed to the retention and stability of the red color of the samples of beef burgers during the storage of the frozen product.O objetivo deste estudo foi avaliar o efeito de extratos de caqui cv.

    During the next three years, the ST/CV group will be deeply involved in the installation works for the LHC project. During this period the need for maintenance activity will decrease. The minimum level will be reached during the “long shutdown” of the PS and SPS machines in 2005. The budget for the maintenance will decrease accordingly, thus the CV group had to review its maintenance strategy. The new contract, which started on January 1st 2003, has been defined to cope with these workload variations during the next years and to guarantee the minimum maintenance activity on the existing equipment. A lump-sum contract based on a win-win strategy has been discarded. The contractor no longer has to guarantee the performance of the CERN cooling and ventilation systems. A new price list strategy based on performance indicators and penalties has been chosen. The contractor now has to guarantee the performance of every maintenance operation demanded by CERN. This modification obliged the Operation section of the...

    Domínguez, César; Heras, Jónathan; Pascual, Vico

    2017-05-01

    The effective processing of biomedical images usually requires the interoperability of diverse software tools that have different aims but are complementary. The goal of this work is to develop a bridge to connect two of those tools: ImageJ, a program for image analysis in life sciences, and OpenCV, a computer vision and machine learning library. Based on a thorough analysis of ImageJ and OpenCV, we detected the features of these systems that could be enhanced, and developed a library to combine both tools, taking advantage of the strengths of each system. The library was implemented on top of the SciJava converter framework. We also provide a methodology to use this library. We have developed the publicly available library IJ-OpenCV that can be employed to create applications combining features from both ImageJ and OpenCV. From the perspective of ImageJ developers, they can use IJ-OpenCV to easily create plugins that use any functionality provided by the OpenCV library and explore different alternatives. From the perspective of OpenCV developers, this library provides a link to the ImageJ graphical user interface and all its features to handle regions of interest. The IJ-OpenCV library bridges the gap between ImageJ and OpenCV, allowing the connection and the cooperation of these two systems. Copyright © 2017 Elsevier Ltd. All rights reserved.

Estudos recentes indicam que a alteração do ciclo de produção da videira através da poda possibilita colher uvas em épocas mais favoráveis à maturação, e com níveis de produção aceitáveis. Neste sentido, o presente trabalho teve como objetivo avaliar o perfil analítico dos vinhos de Syrah de safras de verão e inverno dos anos 2005 e 2006 produzidos em Três Corações (MG. Os vinhos do inverno de 2005 apresentaram valores superiores de pH (3,91 × 3,59, polifenóis totais (49,2 × 32,5, intensidade de cor (10,75 × 5,68, antocianinas (121,48 × 41,09 mg.L-1 , fenólicos totais (2,06 × 1,21 g.L-1, álcool (12,65 × 10,78% v/v e aminas bioativas (10,36 × 4,46 mg.L-1 quando comparados aos de verão. Comportamento semelhante foi obtido na safra de 2006. Os vinhos de inverno apresentaram maior conteúdo de compostos fenólicos, o que indica maior qualidade e maior potencial de guarda. Entretanto, o cultivo em estação seca e o elevado pH do mosto contribuíram para um aumento no teor de aminas bioativas, cuja evolução deve ser controlada na vinificação para evitar riscos à saúde humana.The systematic incidence of rainfall or overcast conditions and high temperatures impair grapes maturation and sanity. Recent studies show that vine growing season alteration through pruning enables berries harvest in climatic conditions more favorable to fruit maturation and that vines respond to pruning with acceptable yield levels. Under these conditions, the objective of the present work was to evaluate the physico-chemical characteristics of Syrah wine from winter and summer vintages of 2005 and 2006 cultivated in the city of Três Corações, State of Minas Gerais, Brazil.

    Full Text Available The effect of water stress on germination of radish seeds is dependent on the presence of light. The effect of pelletization of radish seeds with powdered graphite on the tolerance to water stress under light was analysed. White light and far-red lights were filtered by graphite increasing slightly the tolerance of pelleted seeds to water stress of -0.77MPa. Although red light also inhibited seed germination the graphite had no effect. We propose the pelletization of seeds of Raphanus sativus, at least in cv redondo gigante with graphite as a pratice before planting to increase the tolerance to water stress.O efeito do estresse hídrico é dependente da presença de luz em sementes de rabanete. O efeito da peletização com grafite em pó foi analisado.

    A routine of light or moderate alcohol consumption (≤1 drink/day for women and 1 to 2 drinks/day for men) is associated with a lower risk for all-cause mortality, coronary artery disease (CAD), type 2 diabetes mellitus (T2D), heart failure (HF), and stroke. Conversely, heavy drinking, (>4 drinks/day) is associated with an increased risk for death and cardiovascular (CV) disease (CVD). Excessive alcohol intake trails behind only smoking and obesity among the 3 leading causes of premature deaths in the United States (US). Heavy alcohol use is a common cause of reversible hypertension (HTN), nonischemic dilated cardiomyopathy, atrial fibrillation (AF), and stroke (both ischemic and hemorrhagic). Among males aged 15 to 59 years, alcohol abuse is perhaps the leading cause of premature death. As such, the risk-to-benefit ratio of drinking is less favorable in younger individuals. A daily habit of light to moderate drinking is ideal for those who choose to consume alcohol regularly. Red wine in particular before or during the evening meal is linked with the best long-term CV outcomes. Most of the studies on alcohol and health are observational, and correlation does not prove causation. Health care professionals should not advise nondrinkers to begin drinking because of the paucity of randomized outcome data coupled with the potential for alcohol abuse even among seemingly low risk individuals.

    A haemagglutinin was purified from Japanese Hokkaido red beans (Phaseolus vulgaris cv. Hokkaido red bean) with a procedure that included three chromatographic media. Haemagglutinating activity was adsorbed on DEAE cellulose, Affi-gel blue gel and Mono S. The pure haemagglutinin was a homodimer and each subunit was around 30 kDa in molecular mass. The haemagglutinating activity of this agglutinin could not be inhibited by a variety of simple sugars at 200 mmol L(-1) concentration including alpha-L-fucose, D(+)-galactose, D(+)-glucose, D(+)-glucosamine, D(-)galactosamine, galacturonic acid, (+)-lactose, D(+)-melibose, L(-)-mannose, D(+)-mannose, D-mannosamine, D(+)-raffinose, L-rhamnose, (+)-xylose and galacturonic acid. The haemagglutinating activity was fully retained at pH 4-11 and at 0-80 degrees C, but was completely lost at extreme pH values (0-2 and 13-14) and at very high temperatures (90 degrees C and 100 degrees C). The haemagglutinin exhibited a weak mitogenic activity toward mouse splenocytes, a stronger anti-proliferative activity than Con A toward HepG2 (human hepatoma) cells and inhibited >80% of HIV-1 reverse transcriptase inhibitory activity at 3.3 micromol L(-1). It was devoid of anti-fungal activity. Hokkaido red bean haemagglutinin possesses a potent anti-proliferative effect on HepG2 cells. Copyright (c) 2009 Society of Chemical Industry.

    Avocado (Persea americana Mill, cv. Hass) fruit ranks tenth in terms of the most important products for Mexico. Avocado products are quite unstable due to the presence of oxidative enzymes such as polyphenol oxidase and peroxidase. The present study is to characterize the activity of purified avocado peroxidase from avocado in order to ascertain the biochemical and kinetic properties and their inhibition conditions. Purification was performed by Sephacryl S 200 HR gel filtration chromatography and its estimated molecular weight was 40 kDa. The zymogram showed an isoelectric point of 4.7. Six substrates were tested in order to ascertain the affinity of the enzyme for these substrates. The purified peroxidase was found to have low Km (0.296 mM) and high catalytic efficiency (2688 mM(-1) s(-1)) using 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid), optimum activity being reached at 51°C, pH 3.8. The addition of dithiothreitol, β-mercaptoethanol, ascorbic acid, sodium azide, L-cysteine and Tween-20 had high inhibitory effects, while metals ions such as Cu(+), Fe(2+) and Mn(2+) had weak inhibitory activity on purified avocado peroxidase. The purified avocado peroxidase exhibits high inhibition (Ki = 0.37 µM) with 1.97 µM n-propyl gallate using ABTS as substrate at 51°C, pH 3.8 for 10 min. © 2013 Society of Chemical Industry.

Um dos aspectos mais importantes na produção de alimentos da atualidade é a redução no uso de agroquímicos, com menor contaminação do ambiente e riscos reduzidos de resíduos. Este trabalho visou a comparar os sistemas de Produção Convencional (PC e Integrada (PI de pêssegos e foi realizado no ano de 2001, no município de São Jerônimo - RS, latitude 30°05'52" S, longitude 51°39'08" W e altitude de 46 metros. Áreas de um pomar comercial da cv. Marli foram avaliadas em relação às principais práticas de manejo da planta e do solo, controle fitossanitário, aspectos econômicos, bem como à qualidade da fruta. Na área conduzida sob PI, foram utilizadas as práticas de manejo preconizadas pelas Normas de Produção Integrada de Pêssegos (NPIP e, na área conduzida no sistema de PC, as plantas foram manejadas de acordo com as práticas comumente utilizadas pelo produtor. A produção de pêssegos, em ambos os sistemas, não foi afetada. Na área de PI, houve menor número de pêssegos por planta; entretanto, as frutas apresentaram maior peso médio. A maioria dos pêssegos da PI foram classificados como CAT I (diâmetro superior a 57 mm. As frutas produzidas na PC são, na maioria, de CAT II (de 48 a 57 mm. A qualidade pós-colheita não apresentou diferenças em relação à acidez, firmeza e cor. Com base nestes resultados, podemos concluir que é possível produzir pêssegos de qualidade com produtividade no sistema de PI.The peach-trees cultivation is a very economic important activity in South of Brazil, where highlights the State of Rio Grande do Sul as the largest Brazilian producer. One of the most important aspects in actuality is the food prodution with reduction of agrochemicals components, reducing the risks of environment contamination. This work

    The Rio Grande reservoir is located in the Metropolitan area of Sao Paulo and it is used for recreation purposes and as source water for drinking water production. During the last decades has been detected mercury contamination in the sediments of this reservoir, mainly in the eastern part, near the main affluent of the reservoir, in the Rio Grande da Serra and Ribeirao Pires counties. In the present study bottom sediment samples were collected in four different sites into four sampling campaigns during the period of September 2008 to January 2010. The samples were dried at room temperature, ground and passed through a 2 mm sieve. Total Hg determination in the sediment samples was carried out by two different analytical techniques: neutron activation analysis (NAA) and cold vapor atomic absorption spectrometry (CV AAS). The methodology validation, in terms of precision and accuracy, was performed by reference materials, and presented a recovery of 83 to 108%. The total Hg results obtained by both analytical techniques ranged from 3 to 71 mg kg-1 and were considered similar by statistical analysis, even though NAA technique furnishes the total concentration while CV AAS using the 3015 digestion procedure characterizes only the bioavailable Hg. These results confirm that both analytical techniques were suitable to detect the Hg concentration levels in the Rio Grande sediments studied. The Hg levels in the sediment of the Rio Grande reservoir confirm the anthropogenic origin for this element in this ecosystem. (author)

    Full Text Available The role of the seed coat in the light sensitivity of seeds of Raphanus sativus L. cv. redondo gigante was analysed by germination tests of intact and naked seeds. Far-red light caused high inhibition of seed germination, while under white and red lights low inhibition was found. Naked seeds presented no light sensitivity with high percentage germination under light and darkness. However, incubation of naked seeds in -0.6MPa polyethylene glycol solution resulted in light inhibition as observed in intact seeds. The analysis of the seed coat transmitted light indicated that the filtered light presented the same photoequilibrium of phytochrome when compared to the white light, with a decrease of only 33% in the light irradiance which reaches the embryo.O papel do tegumento sobre a sensibilidade à luz em sementes de Raphanus sativus L. cv. redondo gigante foi analisado por testes de germinação de sementes intactas e nuas. A luz vermelho-extremo inibiu fortemente a germinação, enquanto as luzes branca e vermelha apresentaram baixa inibição. Por outro lado, sementes nuas não apresentaram sensibilidade à luz, com alta porcentagem de germinação tanto na luz como no escuro. Entretanto, a incubação das sementes nuas em condições de estresse em solução de polietilenoglicol a -0,6MPa, resultou em inibição na luz, como observadas em sementes intactas. A análise da luz transmitida pelo tegumento das sementes indicou que a luz filtrada apresenta o mesmo fotoequilíbrio teórico do fitocromo obtido na luz branca, com um decréscimo em apenas 33% da irradiância que atinge o embrião.

    Dormant corms of Gladiolus cv. White Friendship were irradiated with 250, 500, 750, 1000 and 1250 Gy of gamma rays. Reduction in survival, plant height, number of leaves and floret, spike length, leaf and corm size and delayed flowering were recorded after irradiation. Morphological abnormalities in foliage and florets and chromosomal aberration during root tip mitosis increased with increase in exposure. Flowering was ceased cent per cent in highest dose of 1250 Gy. LD 50 on survival basis was found in 750 Gy exposure. MV 2 and MV 3 also followed the similar pattern of results as exhibited by MV 1 plants. Pink flower colour mutation was detected in few plants as sectorial chimeric form in MV 2 in treated population. In MV 3 one plant produced spike with lighter pink florets in 750 Gy treatment.

    Dormant buds of mango (Mangifera indica L. cv. Langra) exposed to acute gamma-irradiation dosages of 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 kiloroentgens (kR), were grafted on to one-year-old seedling stock. Dosages of 2.0 and 3.0 kR were found satisfactory for the purpose, as measured by bud lethality and scion growth. A bud graft from 3.0 kR bore fruits of excellent quality. Compared with the control, the fruits were heavier, larger and had more creamish-yellow pulp. None of the other morphological changes expressed by the mutant fruits, observed over three fruiting seasons, were disadvantageous. The tree habit is being further investigated before the mutant can be considered for release as an improved cultivar. (author)

    Full Text Available The high perishability of papaya (Carica papaya L. reduces its lifespan as well as limits marketing. Coating the fruits is an alternative to aid food preservation. We aimed to evaluate the effects of coating propolis extract on the physicochemical characteristics of papaya stored at room temperature. Solo papayas cv. 'Golden' were randomly divided into five postharvest treatment groups, three forms of dip-coating (70% alcohol, hydroalcoholic extract of propolis to 2.5%, and hydroalcoholic extract of propolis to 5% and two controls (one uncoated and one with refrigerated uncoated fruits. The weight loss, firmness, soluble solids (SS, titratable acidity (TA, SS/TA, and hydrogen potential (pH were evaluated at the intervals of 4 days every 12th storage day. Sensory analysis was performed on the 4th day of storage of papayas and evaluated by untrained through the acceptance testing. Treatments “refrigerated”, “propolis 2.5%”, and “5% propolis” presented with the lowest weight loss. The firmness level for treatment propolis 5% was superior to that of control, alcohol, and 2.5% propolis treatments. The SS was greater for propolis 5% treatment, which only differed from the alcohol treatment. The TA and SS/TA did not vary with the treatments, but with the storage time. The pH of refrigerated papaya showed significant differences in relation to other treatments. The fruits subjected to refrigerated treatment presented with chilling injury. Papayas coated with propolis extract showed sensory acceptability similar to that in other treatments on the 4th day of storage. The coating of propolis extract is a promising alternative for the control of weight loss and for the maintenance of firmness in Solo papaya cv. 'Golden'.

  16. Core Problem: Does the CV Parent Body Magnetization require differentiation?

    2016-12-01

    Evidence for the presence of past dynamos from magnetic studies of meteorites can provide key information on the nature and evolution of parent bodies. However, the suggestion of a past core dynamo for the CV parent body based on the study of the Allende meteorite has led to a paradox: a core dynamo requires differentiation, evidence for which is missing in the meteorite record. The key parameter used to distinguish core dynamo versus external field mechanisms is absolute field paleointensity, with high values (>>1 μT) favoring the former. Here we explore the fundamental requirements for absolute field intensity measurement in the Allende meteorite: single domain grains that are non-interacting. Magnetic hysteresis and directional data define strong magnetic interactions, negating a standard interpretation of paleointensity measurements in terms of absolute paleofield values. The Allende low field magnetic susceptibility is dominated by magnetite and FeNi grains, whereas the magnetic remanence is carried by an iron sulfide whose remanence-carrying capacity increases with laboratory cycling at constant field values, indicating reordering. The iron sulfide and FeNi grains are in close proximity, providing mineralogical context for interactions. We interpret the magnetization of Allende to record the intense early solar wind with metal-sulfide interactions amplifying the field, giving the false impression of a higher field value in some prior studies. An undifferentiated CV parent body is thus compatible with Allende's magnetization. Early solar wind magnetization should be the null hypothesis for evaluating the source of magnetization for chondrites and other meteorites.

    Full Text Available O Brasil produz cerca de 140 milhões de toneladas de alimento por ano; entretanto, a fome ainda é um dos maiores problemas enfrentados por grande parte da sua população. O aproveitamento integral de alimentos é uma alternativa para suprir as necessidades nutricionais e contribuir para reduzir o lixo orgânico. Nesse sentido, cascas, talos, sementes e outras partes, tradicionalmente não utilizadas como alimentos, podem ser incorporadas na dieta alimentar. Estudos revelam que cascas de muitas hortifrutícolas possuem mais nutrientes que determinadas polpas, a parte tradicionalmente consumida. No entanto, o conhecimento sobre a concentração de metais pesados nessas frações também é importante, uma vez que podem provocar intoxicações alimentares, se consumidos, mesmo em concentrações reduzidas. O Brasil é o sétimo produtor mundial de manga e dentre as cultivares de importância comercial, a cv. Tommy Atkins é a mais plantada e exportada pelo Brasil. A pesquisa teve como objetivo determinar a composição centesimal e o perfil de macro e microminerais, inclusive, os elementos-traço, da casca e da polpa de manga cv. Tommy Atkins. A maior fração da composição centesimal da casca estudada foi a umidade, seguida dos carboidratos totais, com destaque para o teor de fibra alimentar total (FAT, que representou cerca 11% dessa quantidade. Já os teores de proteína e de cinzas apresentaram cerca de 2,5%, enquanto a fração lipídica foi inferior aos demais componentes. O perfil de minerais da casca revelou que as concentrações desses elementos foram superiores aos encontrados na polpa, exceto para zinco e ferro. As concentrações de metais pesados presentes na casca, em função das concentrações menores que 0,1 mg/100g, possibilitam a sua utilização na alimentação humana. A composição centesimal e perfil mineral da casca da manga demonstraram a sua importância nutricional e a possibilidade da utilização dessa parte, at

    Full Text Available Abstract The quality of forage production is a prerequisite to raising livestock. Therefore, income losses in this activity, primarily cattle raising, can result in the impossibility of economic activity. Through the qualitative and quantitative anatomical study of Urochloa hybrida cv. Mulato II and U. brizantha cv. Marandu, we searched for descriptions and compared changes in the individual vegetative body from populations with death syndrome pastures (DPS. Specimens were collected at different physiological stages from farms in northern Mato Grosso. After collection, the individuals were fixed in FAA50 and stored in 70% alcohol. Histological slides were prepared from the middle third of the sections of roots, rhizomes, and leaves, and the proportions and characteristics of tissues were evaluated in healthy, intermediate, and advanced stages of DPS. Changes were compared between cultivars. With the advancement of the syndrome, the following changes were observed: a more marked decrease in the length of roots in U. hybrida; disorganization of the cortical region of the roots and rhizome cultivars; fungal hyphae in roots and aerenchyma formation in U. hybrida; a decrease in sclerenchyma fiber proportions in roots and leaves; sclerification of the epidermis of U. brizantha rhizomes; and an increase in pericyclic fibers in U. hybrida. Furthermore, there was a decrease in the volume of epidermal cells of the abaxial face of the leaves of both cultivars, with a greater reduction in U. hybrida; a gradual decrease in thickness in the midrib of leaves similar to leaf mesophyll; conduction system obstructions; partial or total cell lysis in roots and rhizomes affected by the syndrome. Obstructions in sieve tube element and companion cells, and sometimes obstruction in xylem vessel elements. The evolution of DPS in cultivars was similar, but there were variations, arising probably from the physiological response to stress, such as aerenchyma formation in

    The full-length dystrophin protein isoform of 427 kDa (Dp427), the absence of which represents the principal abnormality in X-linked muscular dystrophy, is difficult to identify and characterize by routine proteomic screening approaches of crude tissue extracts. This is probably related to its large molecular size, its close association with the sarcolemmal membrane, and its existence within a heterogeneous glycoprotein complex. Here, we used a careful extraction procedure to isolate the total protein repertoire from normal versus dystrophic mdx-4cv skeletal muscles, in conjunction with label-free mass spectrometry, and successfully identified Dp427 by proteomic means. In contrast to a considerable number of previous comparative studies of the total skeletal muscle proteome, using whole tissue proteomics we show here for the first time that the reduced expression of this membrane cytoskeletal protein is the most significant alteration in dystrophinopathy. This agrees with the pathobiochemical concept that the almost complete absence of dystrophin is the main defect in Duchenne muscular dystrophy and that the mdx-4cv mouse model of dystrophinopathy exhibits only very few revertant fibers. Significant increases in collagens and associated fibrotic marker proteins, such as fibronectin, biglycan, asporin, decorin, prolargin, mimecan, and lumican were identified in dystrophin-deficient muscles. The up-regulation of collagen in mdx-4cv muscles was confirmed by immunofluorescence microscopy and immunoblotting. Thus, this is the first mass spectrometric study of crude tissue extracts that puts the proteomic identification of dystrophin in its proper pathophysiological context. PMID:28248273

    Full Text Available The objective was to evaluate the effect of nitrogen fertilization on the establishment of forage peanut (Arachis pintoi cv. Belmonte propagated vegetatively. The experiment was conducted in a greenhouse in a completely randomized design with treatments arranged in a 2 × 4 factorial design - two ages (70 and 85 days after planting and four nitrogen doses (0, 40, 80 and 120 kg/ha - with four replications. Morphogenetic and structural characteristics and production were evaluated. The nitrogen accelerated the establishment of the forage peanut with an increase in dry weight of green leaves and stolons. The greatest length of stolons (48.0 cm was obtained with a dose equivalent to 86 kg N/ha and higher density of stolons (20 stolons/vase between 78 and 82 kg N/ha. Nitrogen fertilization also reduced the phyllochron from 6.7 to 4.6 days/leaf. These data were more intense at 85 days, suggesting greater photosynthetic contribution during this period related to the large number of leaves after 70 days. Therefore, nitrogen can be an important tool to accelerate the establishment of pure stands of forage peanut.

    2013-09-01

    Accurate and fast detection of infrared (IR) dim target has very important meaning for infrared precise guidance, early warning, video surveillance, etc. In this paper, some basic principles and the implementing flow charts of a series of algorithms for target detection are described. These algorithms are traditional two-frame difference method, improved three-frame difference method, background estimate and frame difference fusion method, and building background with neighborhood mean method. On the foundation of above works, an infrared target detection software platform which is developed by OpenCV and MFC is introduced. Three kinds of tracking algorithms are integrated in this software. In order to explain the software clearly, the framework and the function are described in this paper. At last, the experiments are performed for some real-life IR images. The whole algorithm implementing processes and results are analyzed, and those algorithms for detection targets are evaluated from the two aspects of subjective and objective. The results prove that the proposed method has satisfying detection effectiveness and robustness. Meanwhile, it has high detection efficiency and can be used for real-time detection.

    Rittmann, P.D.

    1984-08-01

    Several user-oriented programs for the Hewlett-Packard HP-41CV are explained. The first program builds, stores, alters, and ages a list of radionuclides. This program only handles single- and double-decay chains. The second program performs convenient conversions for the six nuclides of concern in plutonium handling. The conversions are between mass, activity, and weight percents of the isotopes. The source can be aged and/or neutron generation rates can be computed. The third program is a timekeeping program that improves the process of manually estimating and tracking personnel exposure during high dose rate tasks by replacing the pencil, paper, and stopwatch method. This program requires a time module. The remaining four programs deal with computations of time-integrated air concentrations at various distances from an airborne release. Building wake effects, source depletion by ground deposition, and sector averaging can all be included in the final printout of the X/Q - Hanford and X/Q - Pasquill programs. The shorter versions of these, H/Q and P/Q, compute centerline or sector-averaged values and include a subroutine to facilitate dose estimation by entering dose factors and quantities released. The horizontal and vertical dispersion parameters in the Pasquill-Gifford programs were modeled with simple, two-parameter functions that agreed very well with the usual textbook graphs. 8 references, 7 appendices

  13. A virtual computing infrastructure for TS-CV SCADA systems

    CERN Document Server

    Poulsen, S

    2008-01-01

    In modern data centres, it is an emerging trend to operate and manage computers as software components or logical resources and not as physical machines. This technique is known as â€ワvirtualisation” and the new computers are referred to as â€ワvirtual machines” (VMs). Multiple VMs can be consolidated on a single hardware platform and managed in ways that are not possible with physical machines. However, this is not yet widely practiced for control system deployment. In TS-CV, a collection of VMs or a â€ワvirtual infrastructure” is installed since 2005 for SCADA systems, PLC program development, and alarm transmission. This makes it possible to consolidate distributed, heterogeneous operating systems and applications on a limited number of standardised high-performance servers in the Central Control Room (CCR). More generally, virtualisation assists in offering continuous computing services for controls and maintaining performance and assuring quality. Implementing our systems in a vi...

    Diabetes and cancer are a major global public health problem. Plant-derived agents with undesirable side-effects were required. This study aimed to evaluate antidiabetic and anticancer activities of the ethanolic leaf extract of Mangifera indica cv. Okrong and its active phytochemical compound, mangiferin. Antidiabetic activities against yeast α-glucosidase and rat intestinal α-glucosidase were determined using 1 mM of p-nitro phenyl-α-D-glucopyranoside as substrate. Inhibitory activity against porcine pancreatic α-amylase was performed using 1 mM of 2-chloro-4 nitrophenol-α-D-maltotroside-3 as substrate. Nitrophenol product was spectrophotometrically measured at 405 nm. Anticancer activity was evaluated against five human cancer cell lines compared to two human normal cell lines using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Mango leaf extract and mangiferin exhibited dose-dependent inhibition against yeast α-glucosidase with the IC50 of 0.0503 and 0.5813 mg/ml, respectively, against rat α-glucosidase with the IC50 of 1.4528 and 0.4333 mg/ml, respectively, compared to acarbose with the IC50 of 11.9285 and 0.4493 mg/ml, respectively. For anticancer activity, mango leaf extract, at ≥200 μg/ml showed cytotoxic potential against all tested cancer cell lines. In conclusion, mango leaf possessed antidiabetic and anticancer potential in vitro. PMID:28217550

Para isso, as sementes foram germinadas em meio MS semi-sólido contendo BAP ou ANA e sem esses reguladores de crescimento. As sementes permaneceram nesses meios por um, dois, três e quatro dias, sendo então seus cotilédones inoculados em meio MS contendo diferentes concentrações de BAP (0,5; 0,9; 1,5 e 2,0mg L-1. As maiores taxas de regeneração ocorreram nos cotilédones oriundos de sementes mantidas durante um e dois dias nos meios contendo 0,5 e 0,9mg L-1 de BAP. O aumento da permanência dos explantes nos meios de germinação e as elevadas concentrações de BAP nos meios de regeneração diminuíram a capacidade organogênica dos explantes e incrementaram a formação de calos.The aim of the present study was to optimize a cv. Gaucho melon cotyledon explant regeneration protocol, evaluating the germination media composition and the explant exposition period in these media. For this purpose, seeds were germinated in semi-solid MS medium containing either BAP or ANA, and without growth regulators. The seeds were kept in these media for one, two, three or four days; afterwards, their cotyledons were inoculated in MS medium containing different BAP concentrations (0.5; 0.9; 1.5 and 2.0mg L-1. The highest regeneration rates occurred with cotyledons from seeds which had been kept for one or two days in media containing 0.5 and 0.9mg L-1 BAP. Both the increase in the explant exposition time in germination media and high BAP concentrations in regeneration media decreased explant organogenic capacity, and increased callus formation.

Os frutos foram avaliados após 3 meses de armazenamento mais 3 dias de exposição à temperatura ambiente (18-20ºC. Conforme os resultados, não foi constatada interação entre os fatores, havendo efeito significativo para temperatura somente na firmeza de polpa, em que -1,0ºC apresentou frutos mais firmes. As diferentes pressões parciais de CO2 não influenciaram a perda de peso e a firmeza de polpa. As podridões apresentaram uma resposta linear negativa em relação ao CO2, porém, mantendo elevada ocorrência. Valores de CO2 entre 5 e 10kPa proporcionaram frutos com menor índice de escurecimento de epiderme e com coloração mais amarela e vermelha. O CO2 entre 5 e 10kPa apresentou os melhores resultados, que somados à temperatura de -1,0ºC, foi a melhor condição de armazenamento, que, no entanto, teve o período de conservação inferior a três meses nesta condição, devido às altas perdas por podridões.

    Lettuce (Lactuca sativa, L.) is an important annual plant of the family Asteraceae (Compositae). The commercial lettuce cultivar Tizian has been used in various scientific studies investigating the interaction of the plant with phytopathogens or biological control agents. Here, we present the de novo draft genome sequencing and gene prediction for this specific cultivar derived from transcriptome sequence data. The assembled scaffolds amount to a size of 2.22 Gb. Based on RNAseq data, 31,112 transcript isoforms were identified. Functional predictions for these transcripts were determined within the GenDBE annotation platform. Comparison with the cv. Salinas reference genome revealed a high degree of sequence similarity on genome and transcriptome levels, with an average amino acid identity of 99%. Furthermore, it was observed that two large regions are either missing or are highly divergent within the cv. Tizian genome compared to cv. Salinas. One of these regions covers the major resistance complex 1 region of cv. Salinas. The cv. Tizian draft genome sequence provides a valuable resource for future functional and transcriptome analyses focused on this lettuce cultivar. Copyright © 2017 Elsevier B.V. All rights reserved.

    A novel cyclovirus, CyCV-VN, was recently identified in cerebrospinal fluid (CSF) from patients with central nervous system (CNS) infections in central and southern Vietnam. To explore the geographic distribution of this novel virus, more than 600 CSF specimens from patients with suspected CNS infections in northern Vietnam, Cambodia, Nepal and The Netherlands were screened for the presence of CyCV-VN but all were negative. Sequence comparison and phylogenetic analysis between CyCV-VN and another novel cyclovirus recently identified in CSF from Malawian patients indicated that these represent distinct cycloviral species, albeit phylogenetically closely related. The data suggest that CyCV-VN has a limited geographic distribution within southern and central Vietnam. Further research is needed to determine the global distribution and diversity of cycloviruses and importantly their possible association with human disease.

    Full Text Available This work aims to investigate biofuels for diesel engines produced on a lab-scale from the fresh water microalgae Chlorella vulgaris (FWM-CV. The impact of growing conditions on the properties of biodiesel produced from FWM-CV was evaluated. The properties of FWM-CV biodiesel were found to be within the ASTM standards for biodiesel. Due to the limited amount of biodiesel produced on the lab-scale, the biomass of dry cells of FWM-CV was used to yield emulsified water fuel. The preparation of emulsion fuel with and without FWM-CV cells was conducted using ultrasound to overcome the problems of large size microalgae colonies and to form homogenized emulsions. The emulsified water fuels, prepared using ultrasound, were found to be stable and the size of FWM-CV colonies were effectively reduced to pass through the engine nozzle safely. Engine tests at 3670 rpm were conducted using three fuels: cottonseed biodiesel CS-B100, emulsified cottonseed biodiesel water fuel, water and emulsifier (CS-E20 and emulsified water containing FWM-CV cells CS-ME20. The results showed that the brake specific fuel consumption (BSFC was increased by about 41% when the engine was fueled with emulsified water fuels compared to CS-B100. The engine power, exhaust gas temperature, NOx and CO2 were significantly lower than that produced by CS-B100. The CS-ME20 produced higher power than CS-E20 due to the heating value improvement as a result of adding FWM-CV cells to the fuel.

    Torreya grandis cv. Merrillii, a tertiary survival plant, is a rare tree species of significant economic value and expands rapidly in China. Its special habitat factor analysis has the potential value to provide guide information for its planting, management, and sustainable development, because the suitable growth conditions for this tree species are special and strict. In this paper, the special habitat factors for T. grandis cv. Merrillii in its core region, i.e., in seven villages of Zhuji City, Zhejiang Province were analyzed with Principal Component Analysis (PCA) and a series of data, such as IKONOS image, Digital Elevation Model (DEM), and field survey data supported by the spatial information technology. The results showed that T. grandis cv. Merrillii exhibited high selectivity of environmental factors such as elevation, slope, and aspect. 96.22% of T. grandis cv. Merrillii trees were located at the elevation from 300 to 600 m, 97.52% of them were found to present on the areas whose slope was less than 300, and 74.43% of them distributed on sunny and half-sunny slopes. The results of PCA analysis indicated that the main environmental factors affecting the habitat of T. grandis cv. Merrillii were moisture, heat, and soil nutrients, and moisture might be one of the most important ecological factors for T. grandis cv. Merrillii due to the unique biological and ecological characteristics of the tree species.

    Full Text Available Guava is a fruit with high respiration rates and a very short shelf life. Since information on its respiration pattern is contradictory, the objective was to study the changes occurring in the fruit during ripening and to relate them to the respiration behavior of this fruit. Guavas were picked at the half-ripe stage and stored for 8 days at 22 ± 1 ºC and 78 ± 1% relative humidity. The analyses conducted were: peel and pulp coloration, firmness, total soluble solids (TSS, total titratable acidity (TTA, and ethylene production. According to the results, it was verified that the parameters analyzed apparently do not coincide and are ethylene-independent. There was an accentuated ethylene production during ripening, starting from the 4th day. The ethylene synthesis continued increasing up to the 8th day, when the fruits were already decomposing. It was observed that the firmness decreased sharply in the first three days of ripening, and the skin and pulp color changed during ripening. The TSS, total soluble solids, and the TTA, total titratable acidity, practically did not change during the ripening, even with the increased ethylene production. It can be concluded that guava is a fruit that presents characteristics of climacteric and non-climacteric fruits.A goiaba apresenta altas taxas de respiração e uma vida útil muito curta, e como as informações sobre o padrão respiratório são contraditórias, objetivou-se estudar mudanças ocorridas no fruto durante o amadurecimento e relacioná-las ao comportamento respiratório desses frutos.

    Full Text Available O Brasil produz cerca de 140 milhões de toneladas de alimento por ano; entretanto, a fome ainda é um dos maiores problemas enfrentados por grande parte da sua população. O aproveitamento integral de alimentos é uma alternativa para suprir as necessidades nutricionais e contribuir para reduzir o lixo orgânico. Nesse sentido, cascas, talos, sementes e outras partes, tradicionalmente não utilizadas como alimentos, podem ser incorporadas na dieta alimentar. Estudos revelam que cascas de muitas hortifrutícolas possuem mais nutrientes que determinadas polpas, a parte tradicionalmente consumida. No entanto, o conhecimento sobre a concentração de metais pesados nessas frações também é importante, uma vez que podem provocar intoxicações alimentares, se consumidos, mesmo em concentrações reduzidas. O Brasil é o sétimo produtor mundial de manga e dentre as cultivares de importância comercial, a cv. Tommy Atkins é a mais plantada e exportada pelo Brasil. A pesquisa teve como objetivo determinar a composição centesimal e o perfil de macro e microminerais, inclusive, os elementos-traço, da casca e da polpa de manga cv. Tommy Atkins. A maior fração da composição centesimal da casca estudada foi a umidade, seguida dos carboidratos totais, com destaque para o teor de fibra alimentar total (FAT, que representou cerca 11% dessa quantidade. Já os teores de proteína e de cinzas apresentaram cerca de 2,5%, enquanto a fração lipídica foi inferior aos demais componentes. O perfil de minerais da casca revelou que as concentrações desses elementos foram superiores aos encontrados na polpa, exceto para zinco e ferro. As concentrações de metais pesados presentes na casca, em função das concentrações menores que 0,1 mg/100g, possibilitam a sua utilização na alimentação humana. A composição centesimal e perfil mineral da casca da manga demonstraram a sua importância nutricional e a possibilidade da utilização dessa parte, at

Marandu em pastagens submetidas a quatro taxas de lotação rotacionadas. No período das águas, as taxas de lotação impostas a ambas as pastagens foram de 3, 4, 5 e 6 novilhos/ha e, no período seco, de 2, 3, 4 e 5 novilhos/ha. Nos dois experimentos, o capim-cameroon apresentou maior massa de forragem total e massa de forragem verde, que decresceram com o aumento da desfolha imposta pelas taxas de lotação, principalmente no período seco. Nessa forrageira, o aumento da taxa de lotação comprometeu em maior intensidade a fração de matéria seca de lâmina foliar verde. No período das águas, as taxas de lotação que propiciaram maior oferta de massa seca de forragem total, forragem verde e fração de lâmina foliar foram as de 5 e 4 novilhos/ha, respectivamente, para os capins cameroon e marandu. No período seco, no entanto, os maiores valores obtidos para essas variáveis foram, respectivamente, de 4 e 3 novilhos/ha.

    Frequency-dependent capacitance-voltage fluence (C-V) characteristics of neutron irradiated high resistivity silicon p + -n detectors have been observed up to a fluence of 8.0 x 10 12 n/cm 2 . It has been found that frequency dependence of the deviation of the C-V characteristic (from its normal V -1/2 dependence), is strongly dependent on the ratio of the defect density and the effective doping density N t /N' d . As the defect density approaches the effective dopant density, or N t /N' d → 1, the junction capacitance eventually assumes the value of the detector geometry capacitance at high frequencies (f ≤ 10 5 Hz), independent of voltage. A two-trap-level model using the concept of quasi-fermi levels has been developed, which predicts both the effects of C-V frequency dependence and dopant compensation observed in this study

    Water pollution from the release of industrial wastewater is a serious problem for almost every industry. Enzymes from portulaca, Portulaca oleracea cv., have been investigated for their ability to degrade bisphenol A (BPA), one of the well-known estrogenic pollutants. Enzymatic crude extracts from P. oleracea cv. roots were immobilized on aminopropyl-modified glass beads. They maintained BPA metabolic activity over a broad range of pH values and temperatures. The immobilized enzyme was reusable with more than 50 % of its initial activity retained after 12 batch reactions and no loss of activity after storage for 1 month at -30 °C. Thus, the immobilization of extracts from P. oleracea cv. roots is a useful method for removing BPA from industrial wastewater.

    A short period eclipsing binary star CV Boo is tested for the possible existence of additional bodies in the system with a help of the light equation method. We use data on the moments of minima from the literature as well as from our observations during 2014 May-July. A variation of the CV Boo's orbital period is found with a period of {≈}75 d. This variation can be explained by the influence of a third star with a mass of {≈}0.4 M_{⊙} in an eccentric orbit with e≈0.9. A possibility that the orbital period changes on long time scales is discussed. The suggested tertiary companion is near the chaotic zone around the central binary, so CV Boo represents an interesting example to test its dynamical evolution. A list of 14 minima moments of the binary obtained from our observations is presented.

    This paper presents an approach for kidney segmentation on abdominal CT images as the first step of a virtual reality surgery system. Segmentation for medical images is often challenging because of the objects' complicated anatomical structures, various gray levels, and unclear edges. A coarse to fine approach has been applied in the kidney segmentation using Chan-Vese model (C-V model) and anatomy prior knowledge. In pre-processing stage, the candidate kidney regions are located. Then C-V model formulated by level set method is applied in these smaller ROI, which can reduce the calculation complexity to a certain extent. At last, after some mathematical morphology procedures, the specified kidney structures have been extracted interactively with prior knowledge. The satisfying results on abdominal CT series show that the proposed approach keeps all the advantages of C-V model and overcome its disadvantages.

Os objetivos deste trabalho foram avaliar a produtividade, o estado nutricional e os aspectos quantitativos e qualitativos dos frutos de abacaxizeiro 'Smooth Cayenne' submetidos a doses e parcelamentos do nitrogênio, cultivado em Guaraçaí-SP. O delineamento experimental adotado foi o de blocos ao caso, com quatro repetições e dezesseis tratamentos, num esquema fatorial 4x4, sendo quatro doses de N: 7,5; 15; 22,5 e 30 g planta-1 de N, e quatro parcelamentos: toda a dose aplicada antes da indução floral, metade da dose antes da indução floral e a outra metade após a indução, 2/3 da dose antes da indução e 1/3 da dose após a indução e toda a dose após a indução floral. A aplicação total do N após a indução floral, independentemente da dose, resultou em menores teores foliares de N e dimensões da folha "D", apresentando na colheita frutos pequenos, com menor índice de maturação e maior acidez. Para obtenção de frutos de abacaxi cv. Smooth Cayenne, com maior tamanho, massa e maior teor de SST e menor acidez, a adubação nitrogenada pode ser aplicada em dose total, antes da indução floral, ou parcelada 2/3 antes e 1/3 após esta indução.

    Calcium-aluminum-rich inclusions (CAIs) are the oldest dated materials in the Solar System and numerous previous studies have revealed nucleosynthetic anomalies relative to terrestrial rock standards in many isotopic systems. However, most of the isotopic data from CAIs has been limited to the Allende meteorite and a handful of other CV3 chondrites. To better constrain the isotopic composition of the CAI-forming region, we report the first Sr, Mo, Ba, Nd, and Sm isotopic compositions of two CAIs hosted in the CK3 desert meteorites NWA 4964 and NWA 6254 along with two CAIs from the CV3 desert meteorites NWA 6619 and NWA 6991. After consideration of neutron capture processes and the effects of hot-desert weathering, the Sr, Mo, Ba, Nd, and Sm stable isotopic compositions of the samples show clearly resolvable nucleosynthetic anomalies that are in agreement with previous results from Allende and other CV meteorites. The extent of neutron capture, as manifested by shifts in the observed 149Sm-150Sm isotopic composition of the CAIs is used to estimate the neutron fluence experienced by some of these samples and ranges from 8.40 × 1013 to 2.11 × 1015 n/cm2. Overall, regardless of CAI type or host meteorite, CAIs from CV and CK chondrites have similar nucleosynthetic anomalies within analytical uncertainty. We suggest the region that CV and CK CAIs formed was largely uniform with respect to Sr, Mo, Ba, Nd, and Sm isotopes when CAIs condensed and that CAIs hosted in CV and CK meteorites are derived from the same isotopic reservoir.

    A new meteorite find, named Khatyrka, was recovered from eastern Siberia as a result of a search for naturally occurring quasicrystals. The meteorite occurs as clastic grains within postglacial clay-rich layers along the banks of a small stream in the Koryak Mountains, Chukotka Autonomous Okrug of far eastern Russia. Some of the grains are clearly chondritic and contain Type IA porphyritic olivine chondrules enclosed in matrices that have the characteristic platy olivine texture, matrix olivine composition, and mineralogy (olivine, pentlandite, nickel-rich iron-nickel metal, nepheline, and calcic pyroxene [diopside-hedenbergite solid solution]) of oxidized-subgroup CV3 chondrites. A few grains are fine-grained spinel-rich calcium-aluminum-rich inclusions with mineral oxygen isotopic compositions again typical of such objects in CV3 chondrites. The chondritic and CAI grains contain small fragments of metallic copper-aluminum-iron alloys that include the quasicrystalline phase icosahedrite. One grain is an achondritic intergrowth of Cu-Al metal alloys and forsteritic olivine ± diopsidic pyroxene, both of which have meteoritic (CV3-like) oxygen isotopic compositions. Finally, some grains consist almost entirely of metallic alloys of aluminum + copper ± iron. The Cu-Al-Fe metal alloys and the alloy-bearing achondrite clast are interpreted to be an accretionary component of what otherwise is a fairly normal CV3 (oxidized) chondrite. This association of CV3 chondritic grains with metallic copper-aluminum alloys makes Khatyrka a unique meteorite, perhaps best described as a complex CV3 (ox) breccia.

    Full Text Available Abstract. Monalonion velezangeli is considered one of the most harmful pests of avocado cv. Hass, as far as it attacks vegetative buds, flowers and fruits during all the productive stages of the crop. This situation is aggravated by the lack of knowledge on insect preferences and their relationship with crop phenology. As a contribution to the management of this insect, we studied the relationship between plant phenology and the presence of M. velezangeli, as well as its preferences across tree strata and structures. Data were obtained from six orchards located in the Colombian departments of Antioquia, Caldas and Quindío. After randomly selecting 20 trees at each orchard, 12 branches were marked on each tree, covering the combinations of the four cardinal points with three plant strata (low, medium and high. During a period of 12 months, each branch was monitored by recording its phenological stage (vegetative, flowering and fruiting, the number of individuals of M. velezangeli and the presence of fresh damages on it. An analysis of variance determined that the presence of the insect and its damage were more abundant on the flowering and fruiting branches than on the vegetative ones, as well as in the medium and upper strata of the trees. The damage caused by M. velezangeli was observed to be significantly higher in the reproductive structures (flowers and fruits as compared to the vegetative structures.Resumen.

    MIL 090001 is a large (greater than 6 kg) CV chondrite from the reduced subgroup (CV(sub red)) that was recovered during the 2009-2010 ANSMET field season [1]. The CV(sub red) subgroup meteorites retain primitive characteristics and have escaped the Na and Fe meta-somatism that affected the oxidized (CV(sub ox)) subgroups. MIL 090001 is, however, reported to be altered [1], and thus a major objective of this study is to characterize its mineralogy and petrography and the extent of the alteration.

    Luo, Y.; Morozov, A.; Gordon, D.; Sprangle, P.; Svidzinsky, A.; Xia, H.; Scully, M.; Suckewer, S.

    This paper is about the recent experimental results on amplification of the CV line in the "water window" at 4.03 nm from resonance transition to the ground level of He-like ions in recombination scheme. The indication of the amplification of the CV line has been observed when an elongated narrow plasma channel was created, where high intensity 100 fs beams, optimal for creating CV ions in high density plasma, was propagated up to 0.5-0.6 mm. Without channeling the effective plasma length was much shorter and there was no indication of amplification.The large interest in gain generation in He-like ions in the transition to ground state is due to the possibility of applying a recently developed theory of Lasing Without Inversion (LWI) in XUV and X-ray regions to largely increase the gain for such transitions. The presented results of the indication of CV line amplifications are being discussed from the point of view of using LWI as a superradiance gain increase, hence to construct a very compact soft X-ray laser in the "water window".The last part of the paper is related to the application of the ultra-intensive fs plasma laser, which is currently in the process of development by using stimulated Raman backscattering (SRBS) to create a plasma amplifier and compressor, as the pump for compact laser operating in the "water window" and also at shorter wavelengths.

Marandu e a simulação da taxa de lotação animal por meio do ajuste dos modelos esférico, exponencial e gaussiano ao semivariograma experimental, bem como a robustez das predições. A biomassa da gramínea foi coletada em 50 pontos em uma área de 36,22 ha. A simulação da taxa de lotação foi realizada com base na disponibilidade de folhas verdes em cada ponto amostrado, consumo diário de matéria seca por cada unidade animal (UA e o tempo de pastejo. Os dados referentes às variáveis foram submetidos à análise descritiva, estudo geoestatístico e interpolação por krigagem ordinária. A modelagem variográfica da disponibilidade de matéria seca do capim marandu e a taxa de lotação foram caracterizadas pelos modelos esférico, exponencial e gaussiano. Entretanto, apesar da aparente precisão dos ajustes, o modelo esférico apresentou melhor inferência, segundo o critério de informação de Akaike e soma dos erros ao quadrado. Assim, a adoção de modelos com ajustes de critérios somente visuais levam a estimativas da disponibilidade de biomassa de forragem e da taxa de lotação animal que não refletem a realidade da área.

    As plant fibres are increasingly used in technical textiles and their composites, underlying principles of wound healing in living plant fibres are relevant to product quality, and provide inspiration for biomimetic healing in synthetic materials. In this work, two Linum usitatissimum cultivars differing in their stem mechanical properties, cv. Eden (stems resistant to lodging) and cv. Drakkar (with more flexible stems), were grown without wound or with stems previously wounded with a cut parallel or transversal to the stem. To investigate wound healing efficiency, growth traits, stem biomechanics with Dynamic Mechanical Analysis and anatomy were analysed after 25-day recovery. Longitudinal incisions formed open wounds while transversal incisions generated stem growth restoring the whole cross-section but not the original stem organisation. In the case of transversal wound healing, all the bast fibre bundles in the perturbed area became lignified and pulled apart by parenchyma cells growth. Both Linum cultivars showed a healing efficiency from 79% to 95% with higher scores for transversal healing. Morphological and anatomical modifications of Linum were related to mechanical properties and healing ability. Alongside with an increased understanding of wound healing in plants, our results highlight their possible impact on textile quality and fibre yield.

    Effect of the addition of avocado (Persea americana cv. Hass) or olive (Olea europaea cv. Arbequina) hydroalcoholic leaf extracts (AHE and OHE, respectively) on thermal stability of canola oil (CO) and high oleic sunflower oil (HOSO) during French potatoes frying at 180°C was studied. The extracts were characterized by the total phenolic content, phenol chromatographic profiles and antioxidant activity. B-type trimer procyanidins were the major phenolic compounds identified in AHE. OHE showed higher phenol content, antioxidant activity regarding AHE. CO+OHE and HOSO+OHE decreased the formation of polar compounds and showed an anti-polymeric effect with respect to oils without extracts, whereas AHE extract showed a prooxidant effect on HOSO. Therefore, OHE showed an antioxidant effect on HOSO and CO under the studied conditions. In addition, all systems (CO+AHE, HOSO+AHE, CO+OHE and HOSO+OHE) increased the retention of tocopherols. These results demonstrate the potential utility of OHE as natural antioxidant for oils. Copyright © 2016 Elsevier Ltd. All rights reserved.

    1990-10-01

    A new automated quasi-static C-V measurement technique for MOS capacitors has been developed. This techniques uses an integrating electrometer to measure the charge accumulated on a MOS capacitor in response of a small voltage step. Making use of the internal data storage system of a commercial electrometer and a personal computer, the charge Q on the MOS capacitor is measured as a function of time t and stored. The capacitance is then obtained by analyzing this Q-t data set. A Si MOS sample is measured and analyzed in terms of interface charges as an example. Advantages over a commercial quasi-static meter which uses similar measurement technique are presented. It is also shown that this technique is potentially capable of measuring both high and low frequency C-V curves simultaneously. 9 refs. 5 figs

    Visceral Leishmaniasis is a parasitic disease that affects liver, spleen and bone marrow. According to World Health Organization report, definitive diagnosis is possible just by direct observation of the Leishman body in the microscopic image taken from bone marrow samples. We utilize morphological and CV level set method to segment Leishman bodies in digital color microscopic images captured from bone marrow samples. Linear contrast stretching method is used for image enhancement and morphological method is applied to determine the parasite regions and wipe up unwanted objects. Modified global and local CV level set methods are proposed for segmentation and a shape based stopping factor is used to hasten the algorithm. Manual segmentation is considered as ground truth to evaluate the proposed method. This method is tested on 28 samples and achieved 10.90% mean of segmentation error for global model and 9.76% for local model.

    The heavy metal mercury (Hg) is a neurotoxin known to have a serious health impact even at relatively low concentrations. A slurry method was developed for the sensitive and precise determination of mercury in human serum blood samples by cold vapor generation coupled to atomic fluorescence spectrometry (CV-AFS). All variables related to the slurry formation were studied. The optimal hydrochloric concentration and tin(II) chloride concentration for CV generation were evaluated. Calibration within the range 0.1-10 μg L -1 Hg was performed with the standard addition method, and compared with an external calibration. Additionally, the reliability of the results obtained was evaluated by analyzing mercury in the same samples, but submitted to microwave-assisted digestion method. The limit of detection was calculated as 25 ng L -1 and the relative standard deviation was 3.9% at levels around of 0.4 μg L -1 Hg

    We present the results of a search for extremely metal-poor (EMP), carbon-enhanced metal-poor (CEMP), and cataclysmic variable (CV) stars using a new exploration tool based on linked scatter plots (LSPs). Our approach is especially designed to work with very large spectrum data sets such as the SDSS, LAMOST, RAVE, and Gaia data sets, and it can be applied to stellar, galaxy, and quasar spectra. As a demonstration, we conduct our search using the SDSS DR10 data set. We first created a 3326-dimensional phase space containing nearly 2 billion measures of the strengths of over 1600 spectral features in 569,738 SDSS stars. These measures capture essentially all the stellar atomic and molecular species visible at the resolution of SDSS spectra. We show how LSPs can be used to quickly isolate and examine interesting portions of this phase space. To illustrate, we use LSPs coupled with cuts in selected portions of phase space to extract EMP stars, CEMP stars, and CV stars. We present identifications for 59 previously unrecognized candidate EMP stars and 11 previously unrecognized candidate CEMP stars. We also call attention to 2 candidate He ii emission CV stars found by the LSP approach that have not yet been discussed in the literature.

O objetivo deste trabalho foi verificar as condições da climatização da banana cv. Nanicão e sua influência na conservação pós-colheita de frutos produzidos no Estado de Mato Grosso (MT e procedentes do Estado de Santa Catarina (SC. Foram acompanhadas 12 caixas de banana cv. Nanicão, pesando em torno de 21 kg cada, colhidas em pomar comercial do município de Campo Verde-MT, e também 12 caixas oriundas de SC. Anteriormente à climatização e durante todo o período de vida útil dos frutos, foram monitoradas diariamente a temperatura e a umidade relativa do ambiente, a evolução da coloração dos frutos e a perda de peso destes, assim como o teor de sólidos solúveis totais e de acidez potenciométrica nos frutos verdes e maduros. Verificou-se o maior período de vida útil da banana de SC, 3 dias após a retirada da câmara de climatização, apresentando-se totalmente amarela e com valor máximo de 7,07% de perda de peso dos frutos. A banana cv. Nanicão produzida no MT atingiu valores de perda de peso 5,69% no 2º dia, quando após esse período, não estaria mais própria para a comercialização, atingindo coloração amarelo-pálida. Altos índices de perdas foram detectados no período pós-colheita da banana-'Nanicão', representados principalmente por danos mecânicos na procedente de SC e por danos fisiológicos (despencamento na banana de MT. O despencamento pode estar relacionado com a falta de circulação eficiente do etileno, da exaustão e umidade relativa baixa, 65% em média, durante a climatização.

    Inhibitors of the Wingless-related Integration site (WNT)/β-catenin pathway have recently been under consideration as potential chemopreventive agents against Familial Adenomatous Polyposis (FAP). This autosomal-dominant syndrome is caused by germline mutations in the gene coding for the protein APC and leads to hyperactivation of the WNT/β-catenin signaling pathway, uncontrolled intestinal cell proliferation and formation of adenocarcinomas. The aim of the present work was to: (i) test, on in vitro cultures of cells carrying FAP mutations and on ex vivo biopsies of FAP patients, the WNT inhibitory activity of extracts from two common southern Italian apples, Malus pumila Miller cv. 'Annurca' and Malus domestica cv 'Limoncella'; (ii) identify the mechanisms underpinning their activities and; (iii) evaluate their potency upon gastrointestinal digestion. We here show that both Annurca and Limoncella apple extracts act as WNT inhibitors, mostly thanks to their polyphenolic contents. They inhibit the pathway in colon cells carrying FAP mutations with active dilutions falling in ranges close to consumer-relevant concentrations. Food-grade manufacturing of apple extracts increases their WNT inhibitory activity as result of the conversion of quercetin glycosides into the aglycone quercetin, a potent WNT inhibitor absent in the fresh fruit extract. However, in vitro simulated gastrointestinal digestion severely affected WNT inhibitory activity of apple extracts, as result of a loss of polyphenols. In conclusion, our results show that apple extracts inhibit the WNT pathway in colon cells carrying FAP mutations and represent a potential nutraceutical alternative for the treatment of this pathology. Enteric coating is advisable to preserve the activity of the extracts in the colon-rectal section of the digestive tract.

    Miller, I.; Moore, R.

    1990-01-01

    Root caps of primary, secondary, and seminal roots of Z. mays cv. Kys secrete large amounts of mucilage and are in close contact with the root all along the root apex. These roots are strongly graviresponsive. Secondary and seminal roots of Z. mays cv. Ageotropic are also strongly graviresponsive. Similarly, their caps secrete mucilage and closely appress the root all along the root apex. However, primary roots of Z. mays cv. Ageotropic are non-responsive to gravity. Their caps secrete negligible amounts of mucilage and contact the root only at the extreme apex of the root along the calyptrogen. These roots become graviresponsive when their tips are coated with mucilage or mucilage-like materials. Peripheral cells of root caps of roots of Z. mays cv. Kys contain many dictyosomes associated with vesicles that migrate to and fuse with the plasmalemma. Root-cap cells of secondary and seminal (i.e. graviresponsive) roots of Z. mays cv. Ageotropic are similar to those of primary roots of Z. mays cv. Kys. However, root-cap cells of primary (i.e. non-graviresponsive) roots of Z. mays cv. Ageotropic have distended dictyosomal cisternae filled with an electron-dense, granular material. Large vesicles full of this material populate the cells and apparently do not fuse with the plasmalemma. Taken together, these results suggest that non-graviresponsiveness of primary roots of Z. mays cv. Ageotropic results from the lack of apoplastic continuity between the root and the periphery of the root cap. This is a result of negligible secretion of mucilage by cells along the edge of the root cap which, in turn, appears to be due to the malfunctioning of dictyosomes in these cells.

O primeiro aspecto que surgiu no objeto de análise foi o estudo da liquidez, que é um dos principais exercícios do patrimônio. A estabilidade também é outro exercício básico e imprescindível, pois este é que promove o equilíbrio do organismo administrativo. A ciência contábil após a sua dignidade científica passou a trilhar caminhos esplendorosos, amparados em doutrina que permite alcançar os píncaros filosóficos. Os estudos concernentes aos aspectos de interação da estabilidade na liquidez são, complexos e somente com os recursos filosóficos da contabilidade se pode estudá-los com o panorama holístico e sublime. A filosofia da contabilidade não é alheia às suas práticas tecnológicas, podendo buscar pontos sublimes de panoramas abrangentes, para o estudo analítico da liquidez e estabilidade, observando todas as dimensionalidades e essencialidades de acontecimentos, na comprovação e orientação dos estados de ineficácia e eficácia patrimonial.

    Plaque development for either untreated or UV treated irradiated Herpes simplex virus Type 1 was faster when assayed on UV irradiated CV1 cells. This Large Plaque Effect only occurred if a minimum delay of 12h between cell irradiation and viral inoculation was allowed. Shorter delays gave plaques that were smaller than controls (unirradiated virus-unirradiated cells). The effect was maximal for a 48-h delay and remained unchanged for delays as long as 84h. The effect was greatest for cell exposures of 10Jm -2 . (author)

    The CV-17 cyclotron, isochronous, compact, of variable energy is an accelerator of charged particles and is applied in several situations such as: radioisotopes production, neutron production, irradiation damage analysis, activation analysis. During the production of the particle beams, the parts components of the interior of the cyclotron are irradiated and become radioactive. Due the fact of the cyclotron require maintenance, the knowledgement of the radionuclides present is of primordial importance of the view point of the radioprotection. Taking the excitation function of a nuclear reaction is observed that determined reaction may happen and produce a radionuclide. The radionuclides formed in the parts components by charged particles are presented. (V.R.B.)

Practical training showed that difference in level of compatibility between grapevine rootstock and grafted Vitis vinifera cultivars are existing. Direct effects of these differences are unequal yield of fi rst class grafted grapevine rootlings. In this paper, level of compatibility in nursery between clones of cv. Chardonnay BCL 75, VCR4 and cv. Merlot R18, MCL 519 and grapevine rootstocks Kober 5BB (Vitis berlandieri x V. riparia, SO4 (V. berlandieri x V. riparia and 41B (Chasselas x V.berlandieri were investigated. The trial was conducted in commercial grapevine nursery located in Velika Drenova, Serbia. As an index of compatibility, grade of high quality grapevine grafted rootlings, dry matter in mature shoots and root system development were used. Grafting was done by `tongue grafting` indoor technique. Stratifi cation was done in sand, on temperature of the stratifi cation material of 26-28oC, and humidity of around 90%. Grafted cuttings were waxed twice: before stratifi cation, and before planting in the nursery. Grafted rootlings were classed in two classes according to regulations of quality, (Yugoslav Offi cial Register, 26/79. Grafted rootlings that did not satisfi ed standard criteria were discarded. Both clones of cv. Chardonnay gave the highest percentage of I class grafted rootlings on grapevine rootstock 41B: clone BCL 75 – 60% and clone VCR4 – 61%.

    Full Text Available Coffee plants can be micropropagated by nodal bud sprouting using the 6-benzylaminopurine (6-BA hormone. However, literature reports the use of a wide range of 6-BA, from 0.5 to 88.8 µM L-1. So, this study was performed to narrow that range. Nodal explants of Coffea arabica cv Mundo Novo obtained from in vitro plantlets were inoculated on gelled-MS medium supplemented with different concentrations of 6-BA. Two assays were carried out: in the first one, 6-BA was used at concentrations of 0, 5, 25, 50, and 100 µM L-1, being evaluated at 43 and 123 days. In the second experiment, dosis of 10, 20 and 30 µM L-1, have evaluated at 65 and 100 days. Treatments with 6-BA induced multiple sprouting from the nodal explants, which were best characterized around 100 days after inoculation. The nodal explants grew taller and showed multiple shoots, whereas the effect of 6-BA at 5 to 25 µM L-1 was similar to that with higher concentrations (50 and 100 µM L-1. Nodal explants yielded from 2.9 to 6.0 buds per node, achieving height of 1.3 to 1.5 cm at 5 to 25 µM L-1 of 6-BA, whereas they yielded from 4.3 to 4.9 buds per node but the sprouting grew about 0.8 cm at 50 and 100 µM L-1 of 6-BA. This study indicated that multiple sprouting of lateral buds can be induced by lower concentrations of 6-BA, for example, from 10 to 30 µM L-1, diminishing possible risks of somaclonal variation due to high levels of hormone concentration.O cafeeiro pode ser micropropagado via brotação de gemas laterais, aplicando o regulador de crescimento 6-benzilaminopurina (6-BA.

    2014-02-01

    We explore the relevance of Heterogeneous System Architecture (HSA) in Computer Vision, both as a long term vision, and as a near term emerging reality via the recently ratified OpenCL 2.0 Khronos standard. After a brief review of OpenCL 1.2 and 2.0, including HSA features such as Shared Virtual Memory (SVM) and platform atomics, we identify what genres of Computer Vision workloads stand to benefit by leveraging those features, and we suggest a new mental framework that replaces GPU compute with hybrid HSA APU compute. As a case in point, we discuss, in some detail, popular object recognition algorithms (part-based models), emphasizing the interplay and concurrent collaboration between the GPU and CPU. We conclude by describing how OpenCL has been incorporated in OpenCV, a popular open source computer vision library, emphasizing recent work on the Transparent API, to appear in OpenCV 3.0, which unifies the native CPU and OpenCL execution paths under a single API, allowing the same code to execute either on CPU or on a OpenCL enabled device, without even recompiling.

    Full Text Available The use of pulse solutions containing antimicrobials has been reported, but more research is necessary. To increase vase life and to study their effect on opening inflorescences, silver nanoparticles were used in vase solutions for cv. Puma Chrysanthemum stems. The nanoparticles were synthesized biologically using Chenopodium ambrosioides L. applied at concentrations of 0.01, 0.05, 0.1, 0.5, 1, and 5 mM and compared with a control. Treatments were replicated five times. The stems were cut to 50 cm and observed until the end of their vase life. Low concentrations of silver nanoparticles promoted inflorescence opening and leaf yellowing, while the control leaves remained green, but there was a lower degree of inflorescence opening. High concentrations of silver nanoparticles (0.5, 1, and 5 mM caused senescence due to low water uptake through the stems. Statistical differences in inflorescence opening and diameter, bacterial growth (CFU mL−1 in vase solutions, fresh weight, water uptake, and vase life were found among treatments. Longer vase life and less weight loss were observed in the stems exposed to low concentrations of silver nanoparticles. Low concentrations of silver nanoparticles promoted inflorescence opening and increased vase life of Chrysanthemum cv. Puma.

    Full Text Available Mango (Mangifera indica cv. Ataulfo peel contains bound phenolics that may be released by alkaline or acid hydrolysis and may be converted into less complex molecules. Free phenolics from mango cv. Ataulfo peel were obtained using a methanolic extraction, and their cellular antioxidant activity (CAA and permeability were compared to those obtained for bound phenolics released by alkaline or acid hydrolysis. Gallic acid was found as a simple phenolic acid after alkaline hydrolysis along with mangiferin isomers and quercetin as aglycone and glycosides. Only gallic acid, ethyl gallate, mangiferin, and quercetin were identified in the acid fraction. The acid and alkaline fractions showed the highest CAA (60.5% and 51.5% when tested at 125 µg/mL. The value of the apparent permeability coefficient (Papp across the Caco-2/HT-29 monolayer of gallic acid from the alkaline fraction was higher (2.61 × 10−6 cm/s than in the other fractions and similar to that obtained when tested pure (2.48 × 10−6 cm/s. In conclusion, mango peels contain bound phenolic compounds that, after their release, have permeability similar to pure compounds and exert an important CAA. This finding can be applied in the development of nutraceuticals using this important by-product from the mango processing industry.

    An efficient protocol was standardized for screening of panama wilt resistant Musa paradisiaca cv. Puttabale clones, an endemic cultivar of Karnataka, India. The synergistic effect of 6-benzyleaminopurine (2 to 6 mg/L) and thidiazuron (0.1 to 0.5 mg/L) on MS medium provoked multiple shoot induction from the excised meristem. An average of 30.10 +/- 5.95 shoots was produced per propagule at 4 mg/L 6-benzyleaminopurine and 0.3 mg/L thidiazuron concentrations. Elongation of shoots observed on 5 mg/L BAP augmented medium with a mean length of 8.38 +/- 0.30 shoots per propagule. For screening of disease resistant clones, multiple shoot buds were mutated with 0.4% ethyl-methane-sulfonate and cultured on MS medium supplemented with Fusarium oxysporum f. sp. cubense (FOC) culture filtrate (5-15%). Two month old co-cultivated secondary hardened plants were used for screening of disease resistance against FOC by the determination of biochemical markers such as total phenol, phenylalanine ammonia lyase, oxidative enzymes like peroxidase, polyphenol oxidase, catalase and PR-proteins like chitinase, beta-1-3 glucanase activities. The mutated clones of M. paradisiaca cv. Puttabale cultured on FOC culture filtrate showed significant increase in the levels of biochemical markers as an indicative of acquiring disease resistant characteristics to FOC wilt.

    Full Text Available For the island coastline segmentation, a fast segmentation algorithm for C-V model method based on exponential image sequence generation is proposed in this paper. The exponential multi-scale C-V model with level set inheritance and boundary inheritance is developed. The main research contributions are as follows: 1 the problems of the "holes" and "gaps" are solved when extraction coastline through the small scale shrinkage, low-pass filtering and area sorting of region. 2 the initial value of SDF (Signal Distance Function and the level set are given by Otsu segmentation based on the difference of reflection SAR on land and sea, which are finely close to the coastline. 3 the computational complexity of continuous transition are successfully reduced between the different scales by the SDF and of level set inheritance. Experiment results show that the method accelerates the acquisition of initial level set formation, shortens the time of the extraction of coastline, at the same time, removes the non-coastline body part and improves the identification precision of the main body coastline, which automates the process of coastline segmentation.

    The type of video that used in this proposed hiding a secret information technique is .AVI; the proposed technique of a data hiding to embed a secret information into video frames by using Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT) and Curvelet Transform (CvT). An individual pixel consists of three color components (RGB), the secret information is embedded in Red (R) color channel. On the receiver side, the secret information is extracted from received video. After extracting secret information, robustness of proposed hiding a secret information technique is measured and obtained by computing the degradation of the extracted secret information by comparing it with the original secret information via calculating the Normalized cross Correlation (NC). The experiments shows the error ratio of the proposed technique is (8%) while accuracy ratio is (92%) when the Curvelet Transform (CvT) is used, but compared with Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT), the error rates are 11% and 14% respectively, while the accuracy ratios are (89%) and (86%) respectively. So, the experiments shows the Poisson noise gives better results than other types of noises, while the speckle noise gives worst results compared with other types of noises. The proposed technique has been established by using MATLAB R2016a programming language.

    In their groundbreaking work featuring verbal dichotic listening tasks, Mondor and Bryden showed that tone cues do not enhance children's attentional orienting, in contrast to adults. The magnitude of the children's right-ear advantage was not attenuated when their attention was directed to the left ear. Verbal cues did, however, appear to favour the orientation of attention at around 10 years, although stimulus-onset asynchronies (SOAs), which ranged between 450 and 750 ms, were not rigorously controlled. The aim of our study was therefore to investigate the role of both types of cues in a typical CV-syllable dichotic listening task administered to 8- to 10-year-olds, applying a protocol as similar as possible to that used by Mondor and Bryden, but controlling for SOA as well as for cued ear. Results confirmed that verbal cues are more effective than tone cues in orienting children's attention. However, in contrast to adults, no effect of SOA was observed. We discuss the relative difficulty young children have processing CV syllables, as well as the role of top-down processes in attentional orienting abilities.

    A questionnaire of dual bisected selection of CVM, which is an induced approach of intended payment, was suggested to overcome statistical inefficiency of a questionnaire of single bisected selection. In spite of several advantages of it, it is doubted that there would be an occurrence of anchoring effect, which is a psychological source of convenient starting point. Therefore, the general intended payment model, which can review the anchoring effect from CV questionnaire of dual bisected selection, was suggested and a mechanism that can review the anchoring effect from the model. This model is combining the dual variation model by Cameron and Quiggin (1994) with the results of bisected selective responses of a firstly presented particular amount as an explanatory variable of the second interior intended payment amount. If the sign of coefficient of the results of bisected selective responses of a firstly presented particular amount was negative and statistically significant, then it can be said that there is an anchoring effect. However, when there is uncertainty of occurrence of anchoring effect from the coefficient review, there is no need to worry about the anchoring effect if the average of estimated values of intended payment amount from two responses were different. As a result of applying this model and mechanism to CV materials on the improvement of water quality of the Han River, there is no need to worry about the anchoring effect.

    Full Text Available The Instituto Nacional de Investigaciones Agrícolas (INIA, Venezuela, is producing potato seed by biotechnology in its National Seed Plan. The seeds needed are greater than the installed capacity. The acquisition of temporary immersion system (ITS enables developing research in the production of seed potatoes to ensure quality, efficiency and reduced production costs. The purchase of seeds will decrease and contribute to food security and sovereignty of the country. This work was aimed to obtain potato microtubers cv. ‘Andinita’ in SIT. In vitro plants propagated by organogenesis and SIT in 10 liters capacity were used. Explants (100 were inoculated per pot. After five weeks in multiplication a change of culture medium was carried out to induce tuberization. Three immersion frequencies were tested. Plant height was measured and the number of microtubers and fresh dough was quantified. Potato microtubers cv. ‘Andinita’ in SIT were obtained. The best results were achieved with immersions every four hours, averaging five to seven microtubers per plant (approximately 600 microtubers per culture vessel, with sizes between 4 and 16 mm, with an average of 3 g fresh weight, which ensured budding efficiency and allow direct field planting. This result constitutes the first report of the use of SIT for propagation of potatoes in Venezuela. This is a new possibility to use SIT in other varieties. Key words: shoot tip, immersion frequency, seed

    Full Text Available The genus Heliconia is commercially detached by the exotic appearance of the inflorescences but is susceptible to lack of moisture in the soil, being necessary the irrigation management. In this sense, the objective was to evaluate the effect of different irrigation levels on the plant growth and productive characters of Heliconia psittacorum cv. Golden Torch cultivated in vase. The experiment was conducted from March to October 2014, in a randomized blocks design. Five treatments corresponding to the different irrigation levels were used [50, 75, 100, 125 and 150% of the evaporation measured in Class A (ECA] with four replicates and two plants per replicate. The following evaluations were carried out: number of days for the emergence of the first tiller, number of days for the emergence of the first inflorescence, number of days for the inflorescence harvest, crop cycle, diameter of the flower stem, length of the flower stem, inflorescence length, plant high, number of tillers and productivity of flower stems. Chlorophyll and leaf area measurements were performed. The irrigation levels tested significantly influenced the number of days for the first inflorescence harvest, length of the flower stem and inflorescence length. The irrigation level of 150% ECA provided better results for the length of the flower stem, inflorescence length and for leaf area but without differences from 75%, 100% and 125% ECA. Thus, for the cultivation of the heliconia cv. Golden Torch in pot can be recommended the level corresponding from 75% to 150% ECA.

    Full Text Available The use of methyl jasmonate has demonstrated its efficiency to extend the vase life of cut flowers. The objective of this study was to evaluate the effect of methyl jasmonate associated with storage at low temperatures on the postharvest quality of Rosa cv. Avalanche stems. The treatments consisted of 125, 250, 500 and 1000 μM of methyl jasmonate, besides the control with distilled water. The flower buds were sprayed with 4 mL of the solution, according to the treatments, and then kept in a cold chamber (1 °C for periods of 2 and 6 days. Subsequently, the stems were taken to the postharvest laboratory at a temperature of 16 °C. Better quality, higher fresh weight and water absorption were observed in flower stems stored for 2 days. The application of methyl jasmonate caused less turgescence and greater darkening of roses. It was possible to conclude that two days is the best storage time at 1 °C and the use of methyl jasmonate does not maintain the quality of roses cv. Avalanche after harvest.

    Mango ( Mangifera indica cv. Ataulfo) peel contains bound phenolics that may be released by alkaline or acid hydrolysis and may be converted into less complex molecules. Free phenolics from mango cv. Ataulfo peel were obtained using a methanolic extraction, and their cellular antioxidant activity (CAA) and permeability were compared to those obtained for bound phenolics released by alkaline or acid hydrolysis. Gallic acid was found as a simple phenolic acid after alkaline hydrolysis along with mangiferin isomers and quercetin as aglycone and glycosides. Only gallic acid, ethyl gallate, mangiferin, and quercetin were identified in the acid fraction. The acid and alkaline fractions showed the highest CAA (60.5% and 51.5%) when tested at 125 µg/mL. The value of the apparent permeability coefficient (Papp) across the Caco-2/HT-29 monolayer of gallic acid from the alkaline fraction was higher (2.61 × 10 -6 cm/s) than in the other fractions and similar to that obtained when tested pure (2.48 × 10 -6 cm/s). In conclusion, mango peels contain bound phenolic compounds that, after their release, have permeability similar to pure compounds and exert an important CAA. This finding can be applied in the development of nutraceuticals using this important by-product from the mango processing industry.

    Full Text Available One of the most important limiting factors in spread of apricot in Iran is late spring frost, which damages flower bud and decrease total yield of crop. It has been found that ascorbic acid (AA plays a beneficial role during plant response to chilling and freezing stresses. To evaluate the effects of AA on alleviating of cold stress, the flower buds of Prunus armeniaca L. cv. Shahroudi were sprayed at pink cluster stage with AS at 4 levels (0, 100, 200 and 300 mg. L-1 and were then exposed to artificial cold stress (4 h at –4 °C or without cold stress (+ 25°C. Experimental attributes including electrolyte leakage (EL of flower buds and percentage of damage of pistil, anthers and petals to temperature treatments were determined. The results showed that at - 4°C the lowest and highest percentage of damage and EL of flower buds were observed in application of 200 and 0 mg. L-1 AA, respectively. The highest and lowest percentage of damage of flower organs and EL were obtained in application of 300 and 200 mg. L-1 AA, respectively at + 25 °C. Based on the results of this experiment, AA alleviates the negative effect of cold stress on EL and flower organ damages in apricot cv. Shahroudi, depending on the concentrations of AA used.

    Electrical properties of Schottky- and metal-insulator-semiconductor (MIS)-gate SiGe/Si high electron mobility transistors (HEMTs) were investigated with capacitance-voltage (C-V) measurements. The MIS-gate HEMT structure was fabricated using a SiN gate insulator formed by catalytic chemical vapor deposition (Cat-CVD). The Cat-CVD SiN thin film (5 nm) was found to be an effective gate insulator with good gate controllability and dielectric properties. We previously investigated device characteristics of sub-100-nm-gate-length Schottky- and MIS-gate HEMTs, and reported that the MIS-gate device had larger maximum drain current density and transconductance (g m ) than the Schottky-gate device. The radio frequency (RF) measurement of the MIS-gate device, however, showed a relatively lower current gain cutoff frequency f T compared with that of the Schottky-gate device. In this study, C-V characterization of the MIS-gate HEMT structure demonstrated that two electron transport channels existed, one at the SiGe/Si buried channel and the other at the SiN/Si surface channel

O momento adequado para o transplante foi avaliado através da leitura de uma repetição adicional utilizada como controle. Obteve-se enraizamento em todas as combinações de tratamento, mesma na ausência de IBA. De maneira geral o tratamento rápido tende a ser mais facilmente eficiente quando combinado com as maiores dosagens, enquanto os tratamentos mais demorados com as menores dosagens.The effect of rising concentrations of indolbutyric acid (IBA solutions was evaluated with different exposition times in stem cuttings of Chrysanthemum morifolium cv. White Reagan 606. The applied concentrations were 0,500,1000 and 1500 ppm of IBA during 5s, 1h and 2h, in a randomized complete split-plot block design, with IBA concentrations as main treatment. The experiment was installed in styrofoam trays in a green-house with a mist device and vermiculite as substrate. Transplanting time was determined by an additional block. All treatments induced rooting even in the absence of IBA. In a general sense the fastest treatments tended to be the more efficient when combined with higher concentrations.

    Full Text Available O objetivo deste trabalho foi verificar o efeito de diferentes tensões de água no solo e diferentes concentrações de boro, na fertilidade de gemas de videira cv. Itália, manejada sob o sistema de poda mista. O experimento foi conduzido em pomar comercial, no município de Petrolina-PE. O delineamento experimental utilizado foi o de blocos ao acaso, em esquema fatorial 3x3: três tensões indicativas para a recarga hídrica por irrigação (-30 kPa, -50 kPa e -70 kPa e três concentrações de boro (3%, 6% e 9%, com três repetições e duas plantas por parcela. A testemunha não recebeu aplicações com boro e o solo foi mantido com umidade na capacidade de campo (-10 kPa. As variáveis analisadas foram fertilidade de gemas, índice relativo de clorofila (IRC e área foliar. Os dados foram interpretados por meio de análise de variância e regressão, e os modelos escolhidos com base na significância do coeficiente de regressão (R² > 0,70. Verificou-se que a fertilidade de gemas mostrou efeito linear negativo em função do aumento da tensão de água no solo, diminuindo de 31,88% (-30 kPa, para 23,66% (-70 kPa. Contudo, a fertilidade de gemas nas videiras submetidas a uma restrição hídrica de -30 kPa foi superior à tensão de -10 kPa; o boro a 3% propiciou a maior taxa de fertilidade de gemas em comparação aos demais tratamentos com boro; a restrição hídrica no solo a -30 kPa ocasionou economia no volume de água aplicada da ordem de 35,4% em comparação ao manejo com -10 kPa; o índice relativo de clorofila aumentou linearmente com o acréscimo das tensões de água no solo e houve maior expansão da área foliar em plantas submetidas ao manejo da irrigação na capacidade de campo.

    Full Text Available Nicotine is the major alkaloid compound in cultivated tobacco (Nicotiana tabacum that could potentially be converted into carcinogenic compound (nor-nicotine. The PMT gene encoding putrescine N-methyltransferase (PMT is one of the two key genes that play a prominent role in nicotine biosynthesis. The aimed of this study was to isolate and characterize the cDNA sequence originated from Indonesian local tobacco cv. Sindoro1 (Ntpmt_Sindoro1. The results showed that the Ntpmt_Sindoro1 was 1124 bp in length. This cDNA fragment encodes for 374 amino acid residues. The predicted polypeptide from the cDNA is a hidrophilic protein, and has a predicted molecular weight of 40.95 kDa. The predicted amino acids sequence also showed high similarity to the PMT gene product Nicotiana sp. available in the GenBank data base. The amino acid sequences also exert conserved residues specifically exhibited only by PMT gene originated from N. tabacum. Clustering analysis revealed that Ntpmt_Sindoro1 belongs to the same clade as the PMT3 gene, a member of the N. tabacum PMT gene family. The Ntpmt_Sindoro1 cDNA sequence covering exon1-exon8 of the PMT gene fragment has been registered in the GenBank data base, under the accession number JX978277.

    Enhanced reactivation of UV- and γ-irradiated herpes virus was investigated by the plaque assay on CV-1 monkey kidney monolayer cells irradiated with UV light or X-rays. Both UV- and X-irradiated CV-1 cells showed enhancement of survival of UV-irradiated virus, while little or no enhancement was detected for γ-irradiated virus assayed on UV- or X-irradiated cells. The enhanced reactivation of UV-irradiated virus was greater when virus infection was delayed 24 or 48 h, than for infection immediately following the irradiation of cells. Thus the UV- or X-irradiated CV-1 cells are able to enhance the repair of UV damaged herpes virus DNA, but not of γ-ray damaged ones. (author)

    The present study aimed to investigate the effect of electroacupuncture stimulation at CV4 (also termed Guanyuan) on femoral osteocalcin also termed bone gla protein (BGP), alkaline phosphatase (ALP), bone mineral density (BMD) and biomechanics, as well as the Wnt‑β‑catenin signaling pathway in rats with postmenopausal osteoporosis. Female Sprague‑Dawley rats (4.5‑months old) were randomly divided into sham, Ovx, CV4 and mock groups (n=10/group). With the exception of those in the sham group, the rats were ovariectomized to induce postmenopausal osteoporosis. The rats in the CV4 and mock groups were given electroacupuncture at CV4 and non‑acupoint, respectively. The rats in the Ovx model and sham groups underwent identical fixing procedures, but did not undergo electroacupuncture. Following treatment, hematoxylin and eosin staining was used to observe morphological changes in the left femoral trabecular bone, and a three‑point‑bending test was used to analyze femur biomechanics and determine the BMD. In addition, an enzyme‑linked immunosorbent assay was used to measure the serum levels of ALP/BGP and reverse transcription‑quantitative polymerase chain reaction was used detect the expression levels of Wnt3a, β‑catenin and Runx2. In the present study, it was demonstrated that electroacupuncture at CV4 significantly improved the osteoporotic morphological changes that occurred in the ovariectomized rats, increased serum ALP and BGP levels, enhanced the maximum and fracture loads, increased BMD (Pelectroacupuncture stimulation at CV4 affected bone formation and promoted bone metabolism in rats with postmenopausal osteoporosis, possibly by activating the Wnt‑β‑catenin signaling pathway.

    This work details the analysis of wafer level global process variability in 28 nm FD-SOI using split C-V measurements. The proposed approach initially evaluates the native on wafer process variability using efficient extraction methods on split C-V measurements. The on-wafer threshold voltage (VT) variability is first studied and modeled using a simple analytical model. Then, a statistical model based on the Leti-UTSOI compact model is proposed to describe the total C-V variability in different bias conditions. This statistical model is finally used to study the contribution of each process parameter to the total C-V variability.

  15. Inducing gravitropic curvature of primary roots of Zea mays cv Ageotropic

    Science.gov (United States)

    Moore, R.; Evans, M. L.; Fondren, W. M.

    1990-01-01

    Primary roots of the mutant 'Ageotropic' cultivar of Zea mays are nonresponsive to gravity. Their root caps secrete little or no mucilage and touch the root only at the extreme apex. A gap separates the cap and root at the periphery of the cap. Applying mucilage from normal roots or substances with a consistency similar to that of mucilage to tips of mutant roots causes these roots to become strongly graviresponsive. Gravicurvature stops when these substances are removed. Caps of some mutants secrete small amounts of mucilage and are graviresponsive. These results indicate that (a) the lack of graviresponsiveness in the mutant results from disrupting the transport pathway between the cap and root, (b) movement of the growth-modifying signal from the cap to the root occurs via an apoplastic pathway, and (c) mucilage is necessary for normal communication between the root cap and root in Zea mays cv Ageotropic.

    Mutation induction was used with the objective of obtaining mutants for flower colour of chrysanthemum, cv. Repin (pink colour). Rooted cuttings were irradiated with 20 Gy of gamma rays and before the selection the cutting back method was used to advance the generations. The frequency of colour mutants observed was 5.8%. Among the mutants obtainedthe white and dark-pink-coloured ones were evaluated in yield trial and post-harvest. The results indicated that these mutants mantained the same agronomical characteristics showed by the control, with the exception of plant height in the white mutant that was shorter. Due to commercial interest of the producers, these mutants were multiplied and released as new cultivars. The white flower colour mutant was named Cristiane and the dark-pink, Ingrid. This was the first example of cultivars from an ornamental plant released by mutation breeding in Brazil. (author)

    2015-02-01

    Full Text Available Aimed at the established telenanomanipulation system, the method of extracting location information and the strategies of probe operation were studied in this paper. First, the machine learning algorithm of OpenCV was used to extract location information from SEM images. Thus nanowires and probe in SEM images can be automatically tracked and the region of interest (ROI can be marked quickly. Then the location of nanowire and probe can be extracted from the ROI. To study the probe operation strategy, the Van der Waals force between probe and a nanowire was computed; thus relevant operating parameters can be obtained. With these operating parameters, the nanowire in 3D virtual environment can be preoperated and an optimal path of the probe can be obtained. The actual probe runs automatically under the telenanomanipulation system's control. Finally, experiments were carried out to verify the above methods, and results show the designed methods have achieved the expected effect.

The problem at hand is inspecting the cavity for defects, little bubbles of niobium on the surface of the cavity. Thousands of pictures have to be taken of a single cavity and then looked through to see how many defects were found. A C + + program with Open Source Computer Vision (OpenCV) was constructed to reduce the number of hours searching through the images and finds all the defects. Using this code, the SRF group is now able to use the code to identify defects in on-going tests of SRF cavities. Real time detection is the next step so that instead of taking pictures when looking at the cavity, the camera will detect all the defects.

    Research has shown that the risk of hot spots in the drinking water pipes is very high. Hot spots are, for example, caused by central heating pipes that are too close to the water pipes. The water pipes may be 25 C for a long period, thus creating the risk of legionella growth. The various disciplines need to be careful in the design stage and building stage to prevent such situations from occurring. [Dutch] Onderzoek heeft uitgewezen dat het risico op 'hotspots' in de drinkwaterleidingen erg groot is. Hotspots worden bijvoorbeeld veroorzaakt door cv-leidingen die te dicht in de buurt van waterleidingen lopen. Die waterleidingen kunnen dan langdurig warmer zijn dan 25C en daardoor gevaar opleveren voor legionellagroei. Het vereist zorg van meerdere disciplines in de ontwerpfase en de bouwfase om deze situaties te vermijden.

    Full Text Available Differential effect of plant growth regulators and additives in proliferation of 18-month-old calli of Ananas comosus L. cv. Moris were assessed in vitro. The proliferation of callus relied on the growth regulators and additives. Of the different auxins supplemented in the Murashige and Skoog (MS media, 32.22 μM α-naphthaleneacetic acid (NAA gave the highest mean fresh weight of callus (46.817 g. Medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D was inferior to NAA, while b-naphthoxy acetic acid (BNOA and p-chlorophenoxy acetic acid (4-CPA were not effective in proliferating 18-months old callus. Addition of casein hydrolysate and coconut water to NAA supplemented medium showed better proliferation and production of callus. However, in terms of callus production, NAA at 32.22 μM was economically better.

    A formal compositional study of the proanthocyanidins of Vitis vinifera L. cv. Carménère was conducted in this work. We first characterized the polymeric proanthocyanidins of Carménère skins, seeds, and wines. In addition, the wine astringency was analyzed and compared with Cabernet Sauvignon. Although Carménère wines had a higher proanthocyanidin concentration and mean degree of polymerization than Cabernet Sauvignon wines, the former wines were perceived as less astringent. The low seed/skin proportion in Carménère wines as compared to other varieties, as evidenced by the reduced number of seeds per berry and the higher amount of epigallocatechin subunits of Carménère wine proanthocyanidins, could explain this apparent paradox.

    Black rice is a type of pigmented rice with black bran covering the endosperm of the rice kernel. The main objective of the present study was to provide details information on the proximate composition of third generation of gamma irradiated black rice (Oryza sativa L. cv. Cempo ireng). In respect to the control, generally speaking, there were no significant changes of moisture, lipids, proteins, carbohydrates and fibers contents have been observed for the both gamma irradiated black rice. However, the 200-BR has slightly better nutritional value than that of 300-BR and the control. The mineral contents of 200-BR increased significantly of about 35% than the non-gamma irradiated black rice.

    Solid phase microextraction and simultaneous distillation-extraction combined with GC-FID, GC/MS, aroma extract dilution analysis and odour activity values were used to analyse volatile compounds from guava (Psidium guajava L. cv. Red Suprema) and to estimate the most odour-active compounds. The analysis led to the detection of 141 compounds, 121 of which were positively identified. The composition of guava fruit volatiles included 43 esters, 37 terpenes, 18 aldehydes, 16 alcohols, ten acids, six ketones, four furans and seven miscellaneous compounds. Seventeen odorants were considered as odour-active compounds, with (E)-β-ionone, ethyl hexanoate, ethyl butanoate, hexanal, (Z)-3-hexenal, hexyl acetate, (E)-2-hexenal and limonene contributing most to the typical guava aroma of this cultivar. © 2013 Society of Chemical Industry.

    Full Text Available TAF is the acronym for Articulated Forestry Tractor – a heavy vehicle uses in a logging operation for pulling cut trees out of a forest, in a process called “skidding”. TAF use a cardan shafts transmission from the gear box (CV to distribution box (CD. The distribution box split the movement thru axels or winch. The study applied the cardan theory on a specific case and based on the numeric results a few design modifications are proposed for reducing the angular velocity pulse on the CD input shaft. Theoretical results may have a significant importance in practice, impacting the reduction of transmission noise and vibrations - already claimed in the case of the distribution box for the current constructive solution. An original AutoLISP program are made in order to analyze and optimize the transmission, with graphical results.

    Full Text Available Changes in inhibitor activity in the onion bulbs (Allium cepa L. cv. Sochaczewska during storage were investigated. Onions were dried under an umbrella roof until October 15th or November 15th and thereafter stored in a cold-room at 0-1°C until May 15th. The activity of inhibitors fluctuated markedly during the storage period. At least two peaks and two decreases of inhibitor activity were observed. The weather conditions seemed to strongly influence the level and the date of appearance of inhibitors in onions. Higher inhibitor activity is usually connected with better storage and less sprouting of onions during storage. Prolonged drying under an umbrella roof enhanced onion quality after storage only in these cases when it actually improved the drying of onions.

    The objective of this research was to study the usefulness of nootkatone as a senescence indicator for Rouge La Toma cv. grapefruit (Citrus paradisi Macf.), simulating different treatments that included the normal postharvest handling of citrus fruits: temperature conditioning, cold storage, shipment periods to overseas markets such as Japan and the U.S., marketing conditions, and storage at nonchilling temperature (control treatments). The highest nootkatone levels, determined by GLC-MS analyses, were detected in fruits subjected to control treatments. No significant differences were observed in nootkatone levels between treatments either with or without temperature conditioning prior to the start of the cold storage. Levels of nootkatone increased throughout time for all assayed treatments. The linear regressions of nootkatone levels showed correlation coefficients of 0.80 and 0.83 with storage time (29 and 42 days, respectively). Therefore, nootkatone appears to be a good indicator of senescence for Rouge La Toma grapefruit.

    Full Text Available ABSTRACTThe limited access and the scarcity of good quality water for agriculture are some of the major problems faced in agricultural areas, particularly in arid and semiarid regions. The aim of this study was to evaluate the quality of watermelon seedlings (cv. Crimson Sweet, irrigated with different concentrations of biosaline water of fish culture. The experimental design was completely randomized with five treatments, corresponding to biosaline water at different concentrations (0, 33, 50, 67 and 100%, and four replicates of 108 seedlings. Watermelon seeds were sown in plastic trays filled with commercial substrate and irrigated with different solutions of biosaline water. Seedlings were harvested for biometric analysis at 14, 21 and 28 days after sowing. The use of biosaline water did not affect emergence and establishment of seedlings until 14 days after sowing, the period recommended for transplantation. However, the use of biosaline water affected the development of seedlings with longer exposure time.

    The search for a healthy life has led consumers to rethink their eating habits, consuming fruits and vegetables in place of manufactured products, therefore, the demand for minimally processed products has evolved rapidly. The kiwi fruit (Actinidia deliciosa) has high nutritional value, being rich in C vitamin especially, which has wide acceptance in consumer markets. Thus, along with papaya, passion fruit and pineapple, kiwi can be considered as an additional feature of C vitamin in the diet, or as a substitute for traditional citrus. The aim of this study was to assess the effects of gamma radiation on physical and chemical characteristics of kiwis minimally processed and stored under refrigeration, since this technology increases the shelf life of fruits and vegetables. The Kiwis was stripped, processed and cut into slices, stored in polyethylene bags of 10 cm squared and irradiated at doses of 0 (control), 1 and 2 kGy. A source of {sup 60}Co Gammacell 220, dose rate of 0.429 kGy/hour, in which each treatment had 5 replicates with 15 slices of kiwifruit per replicate. After irradiation the samples were stored in a climatic chamber at 6 degree C (near the temperature of commercial refrigerators). The following criteria were physical chemical analysis: pH, color, chlorophyll content, loss of weight, moisture, acidity and Brix. The analysis were done on 1{sup st}, 7{sup th} and 14{sup th} days after irradiation. The results indicated that gamma radiation did not induce deleterious changes in the physicochemical properties of the kiwi may be used for preservation of minimally processed kiwifruit. (author)

    Tekeľová, Daniela; Bittner Fialová, Silvia; Tóth, Jaroslav; Czigle, Szilvia

    Lamiaceae plants mostly accumulate active ingredients in their leaves. The subfamily Nepetoideae, including the genus Mentha L., is characterized by the presence of essential oil and antioxidant phenolics, chiefly hydroxycinnamic acids with predominance of rosmarinic acid, and flavonoids. Mentha × piperita and M. spicata are the most broadly used mints in both medicine and industry, while M. x villosa is less known in our country. Herbal drugs in the form of leaves are usually analysed unpartitioned, while single leaves insertions have only been studied occasionally. Therefore, the aim of this work was the quantification of the active compounds content in the leaves pairs of Mentha × villosa Huds. cv. Snežná, using pharmacopoeial methods: total hydroxycinnamic derivatives expressed as rosmarinic acid (THD) and luteolin-type flavonoids. THD content ranged from 6.7% to 9.4% in the leaves pairs water extracts, and from 6.6% to 14.0% in methanol extracts. Flavonoids contents, expressed as luteolin-7-O-glucoside, ranged from 4.0% to 8.8% in water extracts, and from 4.0% to 10.5% in methanol extracts. Antioxidant activity (DPPH) expressed as SC50 ranged from 10.2 to 16.9 μg.ml-1 (drug dry weight) in water extracts, and from 10.7 to 21.6 μg.ml-1 in methanol extracts. The highest content of phenolic compounds as well as the highest antioxidant activity were found to be in the top sheet, while the lowest content of phenolic compounds and lowest antioxidant activity were detected in the leaves of the middle stem part.Key words: Mentha × villosa Huds cv.

    The commonly known alternate bearing, i.e. year-to-year change of large and small yields of fruit tree crops worldwide, is often induced by abiotic stress such as late frost, which will eliminate flowers or fruitlets. This study presents an alternative form, biotic biennial bearing, i.e. change of large and small yields of the same trees within the same tree row in the same year. Three methods were developed or modified for the analysis of the number of flower clusters and yield of 2086 apple (Malus domestica Borkh.) cv. 'Elstar' trees. The first method, i.e., based on intersect between yield in year x and year x+1 and flower clusters in year x, yielded 91-106 flower clusters, whereas the second method, i.e., mean yield in year x and year x+1, resulted in a range of 72-133 flower clusters, or 9.6kg/tree necessary for sustainable cultivation of apple cv. 'Elstar'. The third 'biennial bearing index' (BBI), was calculated in three ways as the ratio of differences in tree yields to cumulative tree yield, for individual trees (rather than orchard average) to demonstrate the tree-to-tree alternation. A scheme for the possible underlying regulatory mechanisms was developed, which includes potential elicitors such as light deprivation and subsequent lack of flower initiation, are discussed as a possible result of polar basipetal GA7 transport, cytokinin level in the xylem and phloem and down-regulation of the gene expression of the flowering gene. Suggested countermeasures included early chemical or mechanical thinning. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The investigation was carried out at Germplasm Centre (BAU-GPC, Bangladesh Agricultural University, during March to July 2016 in order to investigate the effect of pre-harvest fruit bagging on post-harvest quality of guava cv. Swarupkathi. Four different bagging materials viz. brown paper bag, white paper bag, white polythene bag, black polythene bag included for the study and uncovered fruits were used as control treatment. The experiment was laid out in randomized complete block design with three replications. Fruit bagging treatments showed significant effects on different parameters studied. It was observed that fruit size, fruit weight, vitamin C concentration, and moisture content increased due to fruit bagging. Fruits were gained maximum in size (6.59 cm length, 5.86 cm diameter and weight (164.26 g under white paper bag followed by white polythene bag (131.3g. The skin color of fruits was very attractive in case of white paper bag than that of other treatments. Total soluble solid concentration of the fruit was found maximum (12.33% Brix under brown paper bag while maximum vitamin C concentration (162.14 mg 100 g-1 was recorded under white paper bag. Uncovered fruits showed maximum total sugar, non-reducing sugar, reducing sugar concentrations (10.13%, 6.05%, 4.08%, respectively.The results revealed that fruit bagging in general, improved the growth and quality of guava fruits as compared to control. Among the various fruit covering materials, white paper bag was found to be the best for overall improvement of physical and chemical quality of guava cv. Swarupkathi.

    Decent optical photometry of the canditate magnetic CV Paloma has uncovered three persistent periods at 157, 146, and 136 min, which we interpret as the manifestation of the orbital motion of the system, the white dwarf's spin, and a related side-band frequency of the other two. All three periodicities are caused by a double-humped modulation of about 1 mag appearing only at certain fractions of the beat cycle, and it probably originates from one or two accretion spots. Our data is consistent with two plausible solutions, with the spin period being either 146 or 136 min. The appearance of a corresponding spin-folded light curve suggests two different scenarios, for which either pole switching between two diametrically opposed accretion regions (for P_spin = 146 min) or pole migration of one single spot (with P_spin = 136 min) is the preferred accretion mode. Complementary ROSAT X-ray observations and low-resolution spectroscopy provide supporting evidence of the magnetic nature of the object. Depending on the choice of the spin period, the degree of asynchronism with respect to the orbital period is 7% or 14%, implying a beat period of 0.7 or 1.4 days. Thus, the source populates the gap between the near-synchronous polars (Paloma is a key object for magnetic CV evolution: it might be the first bona fide transition object between the DQ Her and AM Her system with a white dwarf currently in the process of synchronisation.

    Full Text Available Rooting and acclimatization are limiting steps in plant micropropagation, especially in woody plant species. This study aimed to evaluate the IAA and IBA effect on the in vitro rooting and acclimatization of micropropagated shoots of Japanese plum (Prunus salicina Lindl. cv. América. Shoots from 3 to 4 cm long were inoculated in MS medium with half salt and vitamin concentrations (MS/2 added with IAA and IBA (0, 0.25, 0.5, 0.75 and 1 mg L-1. After a 20-day period in in vitro cultivation, the shoots were evaluated, and then transferred to a greenhouse, and evaluated after 30 days. At the end of the in vitro cultivation period, no significant interactions were observed for number of roots per shoot and rooting percentage, but a significant effect was recorded for auxin type only, for which shoots grown in media added with IBA showed high values - 0.87 and 41.95%, respectively. A linear increase response from 1.45 to 5.75 cm was verified for root length of shoots cultivated in IBA medium; however, no significant effect was observed, and a 0.86 cm average root length per shoot grown in medium added with IAA was found. After 30 days of acclimatization period, the largest survival percentage was obtained from shoots cultivated in medium with 1 mg L-1 of IBA and IAA (88% and 92%, respectively. Although, IBA provided the highest in vitro rooting, most of the surviving shoots were those originated in IAA-added medium, probably because IBA promoted longer fibrous roots, less appropriate for transplant and soil fixation, as they are easily damaged. It was concluded that in vitro rooting with the addition of the highest IAA concentration (1 mg L-1 provided the greatest plant survival during the acclimatization period of the Japanese plum cv. América.

    The aim of this study was to assess the effect of different irrigation strategies on the sensory quality of virgin olive oil VOO) from the cv. cobrancosa- integrated into a protected denomination of origin of Azeite de Tras-os-Montes in the Northeast of Portugal. Three irrigation treatments were applied: (T2)-full irrigation, which received a seasonal water equivalent of 100% of the estimated crop evapotranspiration (ET{sub c}), (T1)-continuous deficit irrigation (30% ETc) and (T0)- rainfed treatment. Data were collected from two consecutive crop years (2005-2006). Olive oil samples were analyzed for volatiles by GC-MS and the results compared with sensory evaluation data. Total volatile compounds tended to decrease with the amount of water applied. The characteristics pungent and bitter were more pronounced in olive oils from T0 and T1, which had higher polyphenolic concentrations, with a strong positive relationship with this variable and the bitter attribute. The Principal Components Analysis clearly separates the three olive oils from 2005, the driest year, and aggregates into a single group the three samples from 2006, suggesting no effect of irrigation on volatile compounds in years with a rainy spring and a marked effect in years with severe drought, suggesting that the effect of the trees’ water status on these variables occurs throughout the crop season and not just during the oil accumulation phase. In general, olive oil from the cv. Cobrançosa is more bitter than pungent and has a typical nutty sensory attribute shown by a strong positive relationship between benzaldehyde and the sensory notes of almonds and nuts.

    Full Text Available Com o crescimento da área cultivada de videira para produção de vinho, tem aumentado a demanda por pesquisas para a região semi-árida do Brasil que resultem no desenvolvimento da viticultura no Vale do São Francisco. Todos os produtos da videira, como uva, vinho, passas, vinagre, têm origem nos açúcares que são produzidos nas folhas durante a fotossíntese e transportados, tanto para os frutos, na época de produção, como para troncos, raízes, folhas não expandidas na fase vegetativa. O objetivo deste trabalho é avaliar a influência da posição no ramo e da variação sazonal no teor de açúcares solúveis e insolúveis nas folhas em videiras para vinho (Vitis vinifera L., cv. Syrah, no Vale do São Francisco. Para tanto, o trabalho foi realizado em um vinhedo comercial e no Laboratório de Sementes/ Fisiologia Vegetal da Embrapa Semi-Árido. A partir dos resultados observados, conclui-se que os açúcares são produzidos em maior quantidade, a partir da quinta folha expandida e acumulam-se em folhas próximas aos cachos. O acúmulo de açúcares nas folhas aumenta após o início da maturação; no entanto, é fortemente influenciado pela temperatura, insolação e radiação.Due to the growth of grapevines cultivated areas for wine production, the requirement for viticulture researches have increased for the Brazilian semi-arid region, that could result in a great development of the viticulture at São Francisco River Valley. All commercialized products of the grapevine, as grape, wine, raisin, vinegar, have their origin in the sugars which are produced in leaves during photosynthesis and transported, in production time, to fruits, trunks, roots and leaves which do not expand in vegetative phase. The objective of this work was to evaluate the influence of the branch position and the seasonal variations in the content of soluble and insoluble sugars in 'Syrah' grapevine for wine production, cultivated at São Francisco River

    Full Text Available The chlorophyll content and fluorescence weredetermined in five-year-old grape plants (Vitis vinifera L. cv.Chardonnay that were subjected to early partial defoliation,in Villa de Leyva, Colombia. The experimental design wascompletely randomized, consisting of two treatments (50%defoliation and control, each with four replications of 35 plants. Every two weeks, one of every two recently-emerged leaves was removed from the non-control plants. The determination of total chlorophyll content was carried out on six leaves per plant using a CCM-200 Plus chlorophyll meter, while chlorophyll fluorescence measurements were taken with one darkadapted leaf per plant using a Junior-PAM fluorometer. Initial fluorescence (Fo, maximum fluorescence (Fm, terminal fluorescence (Ft, variable fluorescence (Fv, electron transport rate (ETR, maximum photochemical quantum yield of PSII (Fv/ Fm, effective photochemical quantum yield of photosystem II (Y(II, photochemical fluorescence quenching coefficient (qP, two non-photochemical quenching coefficients (qN and NPQ,quantum yield of light-induced non-photochemical fluorescence quenching (Y(NPQ, and quantum yield of non-light-induced non-photochemical quenching (Y(NO were measured. The chlorophyll concentration index showed higher values in the defoliated plants. There were no significant differences for the values of Fm, Ft and Fv. Fo was higher in the defoliated plants, while ETR, Fv/Fm and Y(II showed higher values in the control plants. It is evident that a reduction in leaf area modifies thepartitioning of excitation energy destined for photochemicaland non-photochemical processes, thus directly influencing the photosynthetic process of the plants evaluated. / Utilizando un diseño completamente aleatorizado,con dos tratamientos (defoliación al 50% y control y cuatrorepeticiones de 35 plantas cada una, se determinó el contenido y la fluorescencia de la clorofila en plantas de uva, sometidas a defoliación parcial

    Full Text Available This study was done to analyze the physic-chemical, microbiological and sensory qualities of the banana, after being either dry or wet treatment with ozone. For dry processing, the fruits were directly fumigated with ozone for 30 min. The wet treatment included the ozonization of water for 20 min followed by immersion of the fruit in the ozonized water for 10 min. In both treatments, the utilized gas concentration and flow were 0.36 mg L-1 and 1.5 L min-1, respectively. The quality of the fruits was evaluated at the beginning of storage and after 3; 6; 9 and 12 days. The variables analyzed were: fresh mater loss, total titratable acidity, total soluble solids, pH, pulp/peel ratio, color index of the peel, rot severity, microbiological analysis (total fungi and yeast count and sensorial analysis. In general, the fruits immersed in the ozonized water presented better quality, in reference to both the physico-chemical and microbiological parameters, as well as have good sensory acceptance among those tested. It could therefore be concluded that treatment with ozonized water is a new alternative for the postharvest handling of bananas.Esse trabalho teve como objetivo avaliar a qualidade físico-química, microbiológica e sensorial da banana ozonizada por via seca e por via úmida.

    Full Text Available A laboratory experiment was conducted to evaluate the effects of water soluble plant extracts on soil acidity. The plant materials were: black oat, oil seed radish, white and blue lupin, gray and dwarf mucuna, Crotalaria spectabilis and C. breviflora, millet, pigeon pea, star grass, mato grosso grass, coffee leaves, sugar cane leaves, rice straw, and wheat straw. Plant extracts were added on soil surface in a PVC soil column at a rate of 1.0 ml min-1. Both soil and drainage water were analyzed for pH, Ca, Al, and K. Plant extracts applied on the soil surface increased soil pH, exchangeable Ca ex and Kex and decreased Al ex. Oil seed radish, black oat, and blue lupin were the best and millet the worst materials to alleviate soil acidity. Oil seed radish markedly increased Al in the drainage water. Chemical changes were associated with the concentrations of basic cations in the plant extract: the higher the concentration the greater the effects in alleviating soil acidity.Foram conduzidos experimentos de laboratórios para avaliar os efeitos de extratos de plantas solúveis em água na acidez do solo.

    Full Text Available Abstract Background We performed an environmental study of viruses infecting the symbiotic single-celled algae of Paramecium bursaria (Paramecium bursaria Chlorella virus, PBCV in Lake Biwa, the largest lake in Japan. The viruses detected were all Chlorella variabilis virus (CvV = NC64A virus. One of them, designated CvV-BW1, was subjected to further characterization. Results CvV-BW1 formed small plaques and had a linear DNA genome of 370 kb, as judged by pulsed-field gel electrophoresis. Restriction analysis indicated that CvV-BW1 DNA belongs to group H, one of the most resistant groups among CvV DNAs. Based on a phylogenetic tree constructed using the dnapol gene, CvV was classified into two clades, A and B. CvV-BW1 belonged to clade B, in contrast to all previously identified virus strains of group H that belonged to clade A. Conclusions We conclude that CvV-BW1 composes a distinct species within C. variabilis virus.

    Vection (V) refers to the compelling visual illusion of self-motion experienced by stationary individuals when viewing moving visual surrounds. The phenomenon is of theoretical interest because of its relevance for understanding the neural basis of ordinary self-motion perception, and of practical importance because it is the experience that makes simulation, virtual reality displays, and entertainment devices more vicarious. This experiment was performed to address whether an optokinetically induced vection illusion exhibits monotonic and stable psychometric properties and whether individuals differ reliably in these (V) perceptions. Subjects were exposed to varying velocities of the circular vection (CV) display in an optokinetic (OKN) drum 2 meters in diameter in 5 one-hour daily sessions extending over a 1 week period. For grouped data, psychophysical scalings of velocity estimates showed that exponents in a Stevens' type power function were essentially linear (slope = 0.95) and largely stable over sessions. Latencies were slightly longer for the slowest and fastest induction stimuli, and the trend over sessions for average latency was longer as a function of practice implying time course adaptation effects. Test-retest reliabilities for individual slope and intercept measures were moderately strong (r = 0.45) and showed no evidence of superdiagonal form. This implies stability of the individual circularvection (CV) sensitivities. Because the individual CV scores were stable, reliabilities were improved by averaging 4 sessions in order to provide a stronger retest reliability (r = 0.80). Individual latency responses were highly reliable (r = 0.80). Mean CV latency and motion sickness symptoms were greater in males than in females. These individual differences in CV could be predictive of other outcomes, such as susceptibility to disorientation or motion sickness, and for CNS localization of visual-vestibular interactions in the experience of self-motion.

    The excess salt, usually NaCl, inhibits potato plant growth and decreases tubers yield. The use of gamma irradiation to induce new mutants in potato cv. Diamant through tissue culture technique was the main task of this study. Sterilized meristemic tips of potato tubers were cultured on aseptic solid MS-medium, pH 5.7, and were incubated at 20 ± 2 d eg C and 16 hrs day length of 3000-Lux light intensity, to produce virus-free plantlets. Micro-propagation started after 6-8 weeks and plantlets were sub-cultured every 3-4 weeks to increase plantlets population. Plantlets were exposed to 0, or 40 Gy, dose rate 27.7 rad / sec., using Co 60 source at the National Center for Research and Radiation Technology, Cairo, Egypt. Irradiated and unirradiated plantlets were transplanted into 60 ml liquid 1/2MS-medium, pH 5.7, and supplemented with 0, 2000 or 4000 ppm NaCl. And, they were incubated for 2 weeks under the same conditions of temperature and light till the new plantlets were grown up. Healthy plantlets were selected, and micro-propagated up to the sixth vegetative generation (M 1 V 6 ), under the same conditions of salinity and incubation conditions Thereafter, the plantlets were transferred to tuberization liquid 1/2MS-medium, supplemented with the same mentioned concentrations of NaCl, to obtain microtubers. The microtubers were collected after 6-8 weeks and preserved at 10 deg C for 3 months approximately, to break the dormancy. Sprouted microtubers were sown to obtain minitubers, and subsequently macrotubers. All cultures were performed in 30-cm pots in a protected greenhouse, and were irrigated with the same concentrations of NaCl. It could be elicited that cv. Diamant is salinity sensitive. This was evidenced by the decrease in the average number of tubers per plant and average fresh weight of tuber under salinity stress up 4000 ppm NaCl, comparing to unsaline control treatment. Potato plants, which still healthy and produced tubers under salinity stress up to

    Full Text Available Este trabalho examina teoricamente os fatores determinantes da competitividade do produto e do negócio, imprescindíveis à elaboração de estratégias competitivas que visam à obtenção e sustentação de vantagens competitivas. Esse tema é objeto tanto da área de marketing estratégico quanto da de estratégia empresarial. Nas duas áreas, há um ponto de consenso que afirma que a empresa deve diferenciar sua oferta para conquistar e manter vantagem competitiva. Mas, os estudos conduzidos por meio do modelo de Campos e Armas da Competição revelaram que a empresa pode diferenciar seu produto e/ou serviço de modo mais amplo, levando em consideração, na formulação da sua estratégia competitiva, também o campo da competição, quer do produto, quer dela própria. Assim, o objetivo deste artigo é evidenciar que, para a empresa ser competitiva, além de diferenciar seu produto e/ou seu serviço no sentido tradicional, ela precisa: 1 diferenciar seu produto incluindo a definição em quais campos vai competir em cada segmento; e 2 escolher as armas da competição que irá utilizar e definir a intensidade de cada arma. Para atingir tal objetivo, foram necessários vários conceitos do modelo de Campos e Armas da Competição: campo da competição, arma da competição, tese do modelo, configuração dos campos da competição, campo coadjuvante, produto coadjuvante e par produto-mercado. Como uma proposta inovadora sempre desperta dúvida, é mostrado o processo de validação do modelo de Campos e Armas da Competição e são discutidas sua universalidade, consistência e completude.

    Tomato (Solanum lycopersicum) fruit ripening implies that chloroplastic proteins are degraded and new proteins are synthesized. Supplementary nutrition is frequently required when tomato plants begin to fruit and continues until the end of the plant's life cycle. Ammonium assimilation is crucial in these fruit maturation and ripening processes. Glutamine synthetase (GS; EC 6.3.1.2), the main ammonium-fixing enzyme in plants, could not be detected in red fruits of several tomato varieties when growing under standard nutrition. In this paper, we analyze the influence of the nutritional status on the ammonium assimilation capacity of ripe tomato (cv. Micro-Tom) fruit. For this purpose, GS expression and protein profiles were followed in mature green and red fruits harvested from plants grown under standard or supplemented nutrition. Under standard nutrient regime (weekly supplied with 0.5 x Hoagland solution) GS activity was found in chloroplasts (GS2) of mature green fruits, but it was not detected either in the chromoplasts or in the cytosol of red fruits. When plants were shifted to a supplemented nutritional regime (daily supplied with 0.5 x Hoagland solution), GS was found in red fruits. Also, cytosolic transcripts (gs1) preferentially accumulated in red fruits under high nutrition. These results indicate that mature green Micro-Tom fruits assimilate ammonia through GS2 under standard nutrition, while ripe red fruits accumulate GS1 under high nutrition, probably in order to assimilate the extra N-compounds made available through supplemented nutrition.

    Ficin (EC 3.4.22.3), a cysteine endoproteolytic protease in fig trees' latex, has multiple isoforms. Until now, no data on autolysis of individual ficins (ficin isoforms) are available. Following purification, ficins' autolysis was determined by HPLC chromatogram changes and ultrafiltrations at different temperatures and storage times. These results showed that the number of HPLC peaks in latex proteins purification of Ficus carica cv. Sabz varied from previous fig varieties or cultivars. Proteolytic activity of ficins was inhibited by specific cysteine protease inhibitors, confirming the participation of the cysteine residue in the active site. The zeta potential of the first two eluted peaks (I and II) was negative, while that of other peaks were positive. All ficins were susceptible to autolysis when stored at high temperatures. In contrast, only the last two ficins (B, C) were prone to autolysis at cold temperature after long storage period. The rate of degradation of the ficins was significantly increased with the increased storage time. The ficin (A) related to peak (III) had the highest and the lowest surface hydrophobic patches and ratio of autolytic to proteolytic activity, respectively. Copyright © 2012 Elsevier Ltd.

    Loquat cv. Mardan is a promising variety in loquat growing areas of northern Punjab and Khyber Pakhtoon Khwa. Loquat growers face serious issue of true to type plants availability. An attempt was made to explore different vegetative propagation techniques to find out most successful method for nursery industry. In the study propagation through cutting (during spring) and grafting during different suitable seasons (spring and monsoon) was examined. Cuttings were treated with different growth regulators to promote rooting. PBZ, IBA and their combinations were applied to the cuttings. Highest success percentage (40%) was achieved with PBZ. This limited success in rooting of cuttings was complete failure in getting plant survival at the end of the study. In the second phase of the experiment different grafting techniques i.e. tongue, cleft and side grafting were evaluated during two different seasons i.e., spring and monsoon. Cleft grafting in the months of March/ April proved to be most successful method in terms of success (70%), days taken for shoot growth, no. of leaves, shoots length, no. of branches. While in monsoon season side grafting was significantly better with a success of 85%. Overall, monsoon side grafting proved to be more successful than any other method. (author)

    Grapevine is one of the most economically important fruit crops. Molecular markers have been used to study grapevine diversity. For instance, simple sequence repeats are a powerful tool for identification of grapevine cultivars, while amplified fragment length polymorphisms have shown their usefulness in intra-varietal diversity studies. Other techniques such as sequence-specific amplified polymorphism are based on the presence of mobile elements in the genome, but their detection lies upon their activity. Relevant attention has been drawn toward epigenetic sources of variation. In this study, a set of Vitis vinifera cv Pinot noir clones were analyzed using the methylation-sensitive amplified polymorphism technique with isoschizomers MspI and HpaII. Nine out of fourteen selective primer combinations were informative and generated two types of polymorphic fragments which were categorized as "stable" and "unstable." In total, 23 stable fragments were detected and they discriminated 92.5 % of the studied clones. Detected stable polymorphisms were either common to several clones, restricted to a few clones or unique to a single clone. The identification of these stable epigenetic markers will be useful in clonal diversity studies. We highlight the relevance of stable epigenetic variation in V. vinifera clones and analyze at which level these markers could be applicable for the development of forthright techniques for clonal distinction.

    Full Text Available Chitosan, is non-toxic, biodegradable and biocompatible material, which can be used as edible coatings to maintain quality and enhance postharvest life of fruits and vegetables. In this study, the effect of chitosan at 0, 0.5, 1 and 2% concentrations on storage life of cucumber cv. "Zomorod" was investigated. After treatment and keeping in an incubator at 12 °C and 90% relative humidity, the fruits were assessed in 5-days intervals to determine parameters such as firmness, weight loss, vitamin C, titratable acidity, soluble solids and chlorophyll content. Experiment was performed as a split-plot design in time in a completely randomized design with three replications. The results of the experiment showed that chitosan coating, had a significant effect on all traits except titrable acidity. The lowest weight loss and the highest firmness were recorded with 1% chitosan treatment which significantly differed from the control. It is appeared that chitosan coatings could be used to increase the storage life of cucumber fruit and to maintain its quality for a longer period.

    Full Text Available This study was aimed to investigate the effect of heat treatment and shelf life on chilling injury of mango cv.Nam Dok Mai.The heat treatment of mango pulp during storage were determined by hot air oven set at 34 and 38°C for three intervals, as 24, 48, and 72 hours, then they were subsequently stored at 5°C for 10, 20, and 30 days to determine the appropriate shelf life. The findings showed that the symptom of mango fruit after chilling injury appeared within the 30th day of storage at 5°C. Several symptoms of mango fruit after chilling injury treatment were observed, i.e., pitting, browning on the skin, water soaking, and rapid rotting of the fruits that resulted in shorter shelf life. It was found that chilling injury mangoes had lower level of total soluble solid, higher disease incidence, and lower quality of fruit when compared with normal ripe-mango fruits at 25°C. Mango fruits treated at 34°C for either 24 or 48 hours, and at 38°C for 24 hours prior to cold storage at 5°C for 10 and 20 days showed a significant reduction in the chilling injury (CI index when compared to that of non-heated fruits. On the other hand, the heat treatment did not affect fruit weight loss, firmness, color changes, and water soaking at 5°C.

    The importance of ethylene in avocado ripening has been extensively studied. In contrast, little is known about the possible role of abscisic acid (ABA). The present work studied the effect of 1-methylcyclopropene (1-MCP) (0.3 μL L -1 ), e+® Ethylene Remover and the combination thereof on the quality of imported avocado cv. Hass fruit stored for 7 days at 12 °C. Ethylene production, respiration, firmness, colour, heptose (C7) sugars and ABA concentrations in mesocarp tissue were measured throughout storage. Treatment with e+® Ethylene Remover reduced ethylene production, respiration rate and physiological ripening compared with controls. Fruit treated with 1-MCP + e+® Ethylene Remover and, to a lesser extent 1-MCP alone, had the lowest ethylene production and respiration rate and hence the best quality. Major sugars measured in mesocarp tissue were mannoheptulose and perseitol, and their content was not correlated with ripening parameters. Mesocarp ABA concentration, as determined by mass spectrometry, increased as fruit ripened and was negatively correlated with fruit firmness. Results suggest a relationship between ABA and ethylene metabolism since blocking ethylene, and to a larger extent blocking and removing ethylene, resulted in lower ABA concentrations. Whether ABA influences avocado fruit ripening needs to be determined in future research. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    The C-V characteristics of n-channel JFET have been measured under different environmental conditions of temperature up to 140 deg. C and {gamma}-rays up to 100 kGy. For low bias voltage and frequency, the input capacitance, C{sub iss}, is shown to be a direct function of temperature. On the other hand, its value was shown to decrease from 11.68 down to 8.17 nF due to {gamma}-exposure up to 100 kGy. The y-parameters of common source amplifier were calculated under the influence of temperature and {gamma}-rays. The results show that the susceptance component of the admittance increases due to increase in temperature, while decreasing after {gamma}-exposure. Considering the cutoff frequency f{sub T0}, it is clear that as the temperature increases from 30 up to 140 deg. C, f{sub T0} dropped from 47 MHz down to 5 MHz, measured at 0.8 V. On the other hand its value was shown to increase from 43 MHz up to 102 MHz, measured at the same bias voltage, due to {gamma}-exposure up to 100 kGy.

    There is increasing interest in the distribution of sustainable gases (H2, H2/CO, CH4/CO2) and imported gases, such as LNG. The composition of these 'new' gases can differ greatly from the traditional distributed gases. The combustion characteristics may cause undesired effects in household appliances. One of the solutions is to develop equipment that can accept a wide range of gases and mixtures thereof. To this end, within the EDGaR-program (Energy Delta Gas Research) the project 'new gas sensors' is started by the Energy Research Centre of the Netherlands (ECN), Delft University of Technology (TUD) and DNV-KEMA/Gasunie to develop a boiler in which the new gases can be used [Dutch] Er is toenemende interesse in de distributie van duurzame gassen (H2 , H2/CO, CH4/CO2 ) en geimporteerde gassen, zoals LNG.

  1. Transcriptome analysis during ripening of table grape berry cv. Thompson Seedless.

    Directory of Open Access Journals (Sweden)

    Iván Balic

    Full Text Available Ripening is one of the key processes associated with the development of major organoleptic characteristics of the fruit. This process has been extensively characterized in climacteric fruit, in contrast with non-climacteric fruit such as grape, where the process is less understood. With the aim of studying changes in gene expression during ripening of non-climacteric fruit, an Illumina based RNA-Seq transcriptome analysis was performed on four developmental stages, between veraison and harvest, on table grapes berries cv Thompson Seedless. Functional analysis showed a transcriptional increase in genes related with degradation processes of chlorophyll, lipids, macromolecules recycling and nucleosomes organization; accompanied by a decrease in genes related with chloroplasts integrity and amino acid synthesis pathways. It was possible to identify several processes described during leaf senescence, particularly close to harvest. Before this point, the results suggest a high transcriptional activity associated with the regulation of gene expression, cytoskeletal organization and cell wall metabolism, which can be related to growth of berries and firmness loss characteristic to this stage of development. This high metabolic activity could be associated with an increase in the transcription of genes related with glycolysis and respiration, unexpected for a non-climacteric fruit ripening.

    Plant tissues such as somatic embryos, apical shoot tips, axillary shoot buds, embryogenic calli, and protocom-like bodies are potential micropropagules that have been considered for creating synthetic seeds. In the present study, 3-5 mm microshoots of Oryza sativa L. Cv. MRQ 74 were used as explant sources for obtaining synthetic seeds. Microshoots were induced from stem explants on Murashige and Skoog (MS) medium supplemented with 1.5 mg/L benzylaminopurine (BAP). They were encapsulated in 3% (w/v) sodium alginate, 3% sucrose, 0.1 mg/L BAP, and 0.1 mg/L α-Naphthalene acetic acid (NAA). Germination and plantlet regeneration of the encapsulated seeds were tested by culturing them on various germination media. The effect of storage period (15-30 days) was also investigated. The maximum germination and plantlet regeneration (100.0%) were recorded on MS media containing 3% sucrose and 0.8% agar with and without 0.1 mg/L BAP. However, a low germination rate (6.67%) was obtained using top soil as a sowing substrate. The germination rate of the encapsulated microshoots decreased from 93.33% to 3.33% after 30 days of storage at 4°C in the dark. Therefore, further research is being done to improve the germination rate of the synthetic seeds.

    Sweet orange cv. Pera (Citrus sinensis L. Osbeck) harvested from July to November, is the most important cultivar in growing area and consumption in Brazil. To obtain mutants for many characteristics, one-year-old shoots were irradiated at 40 Gy of gamma-rays and the axillary buds were budded. After two cutting-backs, about 7,580 V3M1 plants were obtained. Total of 127 putative mutants were selected from these plants for further examination. The main purpose of this experiment was to obtain late ripening clones which have good fruit quality. These all plants were divided into 15 groups based on the characteristics and random blocks design with 5 replications, including one control plant in each block, was used. The plants were planted 4 X 7 meters and were grown in field condition without artificial irrigation. Ten fruits from each tree were used in evaluating the fruit characteristics such as contents of soluble solid (TSS), acidity, ratio of juice content and skin color, for four years. The data was analyzed by Dunnett test using SAS program. Six clones (9, 10, 16, 21, 58 and 84) were considered as late ripening mutants because they showed lower level of TSS or less ratio of juice content, comparing with the control, in more than one evaluation. The color of the skin of some mutants indicates that they have later ripening characteristics. Other agronomic characteristics are under evaluation in order to see if these mutants can be released as new cultivars

    ABSTRACT Trehalose-6-phosphate (Tre6P) is a precursor of trehalose, which is widespread in nature and greatly influences plant growth and development. Tre6P acts as a signal of carbon availability in many plants, but little is known about the function of Tre6P in rosaceous plants, which have specific sorbitol biosynthesis and transportation pathways. In the present study, Tre6P levels and Sorbitol:Tre6P ratios were analyzed in apple (Malus domestica, Borkh. cv. Gala). Tre6P levels were positively correlated with sorbitol content but negatively correlated with sucrose, glucose, and fructose content in developing fruit. However, under sorbitol-limited conditions, Tre6P levels were positively correlated with both sorbitol and sucrose. In the presence of different exogenous sugar supply, Tre6P levels increased corresponding with sorbitol, but this was not the case with sucrose. In addition, Tre6P content and sorbitol:Tre6P ratios were more highly correlated with ADP-glucose levels under sorbitol-limited conditions and fruit development stages, respectively. These results suggest that Tre6P is more closely related to sorbitol than other soluble sugars and has an important role in influencing carbon metabolism in apple. PMID:28069587

    Imported genetically modified (GM) canola (Brassica napus) is approved by Japanese law. Some GM canola varieties have been found around importation sites, and there is public concern that these may have any harmful effects on related species such as reduction of wild relatives. Because B. juncea is distributed throughout Japan and is known to be high crossability with B. napus, it is assumed to be a recipient of B. napus. However, there are few reports for introgression of cross-combination in B. juncea × B. napus. To assess crossability, we artificially pollinated B. juncea with B. napus. After harvesting a large number of progeny seeds, we observed false hybrids and metaxenia of seed coats. Seed coat color was classified into four categories and false hybrids were confirmed by morphological characteristics and random amplified polymorphic DNA (RAPD) markers. Furthermore, the occurrence of false hybrids was affected by varietal differences in B. napus, whereas that of metaxenia was related to hybridity. Therefore, we suggest that metaxenia can be used as a marker for hybrid identification in B. juncea L. cv. Kikarashina × B. napus. Our results suggest that hybrid productivity in B. juncea × B. napus should not be evaluated by only seed productivity, crossability ought to be assessed the detection of true hybrids. PMID:23136472

    Results of an experimental investigation of the contamination of air sampling inlets by aircraft emissions from the NASA CV-990 research aircraft are presented. This four-engine jet aircraft is a NASA facility used for many different atmospheric and meteorological experiments, as well as for developing spacecraft instrumentation for remote measurements. Our investigations were performed to provide information on which to base the selection of sampling locations for a series of multi-instrument missions for measuring tropospheric trace gases. The major source of contamination is the exhaust from the jet engines, which generate many of the same gases that are of interest in atmospheric chemistry, as well as other gases that may interfere with sampling measurements. The engine exhaust contains these gases in mixing ratios many orders of magnitude greater than those that occur in the clean atmosphere which the missions seek to quantify. Pressurized samples of air were collected simultaneously from a scoop located forward of the engines to represent clean air and from other multiport scoops at various aft positions on the aircraft. The air samples were analyzed in the laboratory by gas chromatography for carbon monoxide, an abundant combustion by-product. Data are presented for various scoop locations under various flight conditions.

    Full Text Available The heat event that occurred in many parts of Australia in 2009 was the worst on record for the past decade, with air temperatures exceeding 40oC for 14 days. Our aim was to assess the impacts of this heat event on vine performance, including ripening, yield and gas exchange of Vitis vinifera cv. Semillon grown in a Riverina vineyard. To assess the affect of high temperatures on Semillon grapevines, the vines were covered with a protective layer to reduce radiant heating and were compared with vines exposed to ambient conditions. The heat event had major effects on ripening; reducing the rate by 50% and delaying harvest ripeness and causing a high incidence of berry shrivel and sunburn. Yield was not affected. Photosynthesis was reduced 35% by the heat event while transpiration increased nearly 3-fold and was accounted for by increased stomatal conductance. The conclusion of this study was that heat events delayed ripening in Semillon berries and caused a significant reduction in berry quality. Strategies to minimise the radiant load during heat events are required and this study has confirmed a protective layer can reduce canopy temperatures and enhance berry quality.

    In this study, the effects of drought stress on pepino seedlings (Solanum muricatum cv. Miski) under natural greenhouse conditions were examined. The control plants were watered at field capacity, and the stress group was not watered. Samples were collected on the 6th, 12th, 24th and 36th days from the leaves of S. muricatum seedlings that, were exposed to drought stress. The relative water content, the total phenolic compounds, and the malondialdehyde, total photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids), and proline contents in these samples were determined. Depending on drought stress, the relative water content, the chlorophyll a, chlorophyll b and carotenoid contents, and the total chlorophylls were found to be lower in the stress group compared with the control group. In contrast, the total phenolic compounds (24th and 36th days) and the proline (12th, 24th and 36th days) levels increased significantly compared with the control group. In addition, a significant increase in the malondialdehyde contents was obtained on the 36th day in the stress group compared with the control group. Such studies may be important for evaluation of metabolic changes in pepino under the drought stress. (author)

    As part of the Binaries Are Not Always Neatly Aligned project (BANANA), we have found that the eclipsing binary CV Velorum has misaligned rotation axes. Based on our analysis of the Rossiter-McLaughlin effect, we find sky-projected spin-orbit angles of βp = -52° ± 6° and βs = 3° ± 7° for the primary and secondary stars (B2.5V + B2.5V, P = 6.9 days). We combine this information with several measurements of changing projected stellar rotation speeds (vsin i sstarf) over the last 30 yr, leading to a model in which the primary star's obliquity is ≈65°, and its spin axis precesses around the total angular momentum vector with a period of about 140 yr. The geometry of the secondary star is less clear, although a significant obliquity is also implicated by the observed time variations in the vsin i sstarf. By integrating the secular tidal evolution equations backward in time, we find that the system could have evolved from a state of even stronger misalignment similar to DI Herculis, a younger but otherwise comparable binary.

    Full Text Available Warehousing management problems that exist in the CV. ABB is the management of warehouses that are susceptible to manipulation of data, methods of work are still very manual such as recording a spare part only handwritten by the warehouse, frequent loss of spare parts in the warehouse, the bon false, and the lack of supervision instruments for oversee the spare parts in the warehouse. To overcome these problems, then made improvements through the implementation of warehouse management information system. Improvements in the form of procurement supervision instruments using the application PHP7 and MySQL, because the existence of the application makes it easy to keep an eye on spare parts in the warehouse, ranging from spare part comes in, spare part out, anyone who requests a part, stock of spare parts of existing in the warehouse, stock outs are used to help finance the manufacture purchase order, reports the spare parts that go into the warehouse of the supplier and request a report part. Not only is it a system of warehousing information can facilitate in making purchase order finance and carry out the approval of the request part of the user. Thus the system becomes more transparent.

    Esca is a destructive disease that affects vineyards leading to important losses in wine production. Information about the response of Vitis vinifera plants to this disease is scarce, particularly concerning changes in plant metabolism. In order to study the metabolic changes in Vitis plants affected by esca, leaves from both infected and non-affected cordons of V. vinifera cv. Alvarinho (collected in the Vinho Verde region, Portugal) were analysed. The metabolite composition of leaves from infected cordons with visible symptoms [diseased leaves (dl)] and from asymptomatic cordons [healthy leaves (hl)] was evaluated by 1D and 2D (1)H-nuclear magnetic resonance (NMR) spectroscopy. Principal component analysis (PCA) of the NMR spectra showed a clear separation between dl and hl leaves, indicating differential compound production due to the esca disease. NMR/PCA analysis allowed the identification of specific compounds characterizing each group, and the corresponding metabolic pathways are discussed. Altogether, the study revealed a significant increase of phenolic compounds in dl, compared with hl, accompanied by a decrease in carbohydrates, suggesting that dl are rerouting carbon and energy from primary to secondary metabolism. Other metabolic alterations detected comprised increased levels of methanol, alanine, and gamma-aminobutyric acid in dl, which might be the result of the activation of other defence mechanisms.

  20. Trehalose 6-phosphate signal is closely related to sorbitol in apple (Malus domestica Borkh. cv. Gala

    2017-02-01

    Full Text Available Trehalose-6-phosphate (Tre6P is a precursor of trehalose, which is widespread in nature and greatly influences plant growth and development. Tre6P acts as a signal of carbon availability in many plants, but little is known about the function of Tre6P in rosaceous plants, which have specific sorbitol biosynthesis and transportation pathways. In the present study, Tre6P levels and Sorbitol:Tre6P ratios were analyzed in apple (Malus domestica, Borkh. cv. Gala. Tre6P levels were positively correlated with sorbitol content but negatively correlated with sucrose, glucose, and fructose content in developing fruit. However, under sorbitol-limited conditions, Tre6P levels were positively correlated with both sorbitol and sucrose. In the presence of different exogenous sugar supply, Tre6P levels increased corresponding with sorbitol, but this was not the case with sucrose. In addition, Tre6P content and sorbitol:Tre6P ratios were more highly correlated with ADP-glucose levels under sorbitol-limited conditions and fruit development stages, respectively. These results suggest that Tre6P is more closely related to sorbitol than other soluble sugars and has an important role in influencing carbon metabolism in apple.

    The use of ionizing irradiation or the use of hot water treatment (HWT) has been demonstrated as a successful commercial phytosanitary treatment during the past two decades. Several countries currently use this technology for commercial treatments to meet plant quarantine requirements. However, hydrothermal treatment has been found to significantly affect the firmness of ;Ataulfo; mango fruit, the susceptibility to damage by cold and it also accelerates their maturation. In this study, we focused on the effect of irradiation doses on the sensorial quality and the physiochemical properties of mango cv ;Ataulfo; compared with the traditional hot water treatment. We found that doses of 150 Gy and 300 Gy of gamma radiation can be applied successfully as well as the hot water treatment. There was no significant difference in between irradiation treatments in terms of weight loss, external and internal color, pH, soluble solids, titratable acidity and firmness, and consumer's acceptance. There was no adverse effect of color appearance, odor and flavor, indicating that consumers will have the willingness to buy and consume irradiated mangoes. Irradiation of mangoes can be a successful post-harvest treatment as an alternative to the hot water treatment.

    Somatic embryogenetic capability and changes in polyamine level and their relationship were analyzed using the long-term (8 years) subcultured calli of Citrus sinensis Osb. cv. Valencia as materials. The results showed that endogenous polyamine contents in embryogenic calli were higher than those in non-embryogenic calli, and the embryogenetic capability was positively correlated to the levels of endogenous polyamines. When the calli were transferred to a differentiation medium, the putrescine content rapidly increased and reached a peak, then fell gradually. Applying exogenous putrescine raised the embryogenesis frequency and endogenous putrescine level. It indicated that increase in putrescine content at early stage of differentiation promoted embryogenesis. With the development of somatic embryo, spermidine content reached its the highest level at globular embryo stage, spermine content rose and reached a peak at a later stage of globular embryo development. Furthermore, changes of the putrescine, spermidine and spermine contents during somatic embryogenesis were similar in Valencia calli which had different ploidy levels, but their contents decreased following the increasing of ploidy level. Changes in arginine decarboxylase activity were positively correlated to the polyamine levels, which suggest that the later is a key factor in regulating the polyamine levels during somatic embryogenesis in citrus plants.

  8. Role of Ethylene in Lactuca sativa cv ;Grand Rapids' Seed Germination.

    Abeles, F B

    1986-07-01

    Promotion of thermoinhibited (30 degrees C) lettuce (Lactuca sativa cv ;Grand Rapids') seed germination by ethylene is similar to the action of the gas in other hormonal systems. Ethylene was more active than propylene and ethane was inactive. An inhibitor of ethylene production, aminoethoxy-vinylglycine, reduced ethylene evolution and germination. Inhibitors of ethylene action such as, 5-methyl-7-chloro-4-ethoxycarbonylmethoxy-2,1,3-benzothiadiazole, 2,5-norbornadiene, and silver thiosulfate inhibited germination and the effect was reversed by the addition of ethylene to the gas phase. The action of ethylene appears to be due to the promotion of radial cell expansion in the embryonic hypocotyl. The action of N6-benzyladenine and fusiccocin, which also overcome thermoinhibition, appears to be due to a promotion of hypocotyl elongation. None of the germination promoters studied appeared to function by lowering the mechanical resistance of the endosperm to embryonic growth. Data presented here are consistent with the view that ethylene plays a role in lettuce seed germination under thermoinhibited and normal conditions.

    The oxidation of chlorophyll a (chl a) catalysed by peroxidase (POD) from mesocarp of the olive fruit (Olea europaea L., cv Hojiblanca) in the presence of H2O2 and 2,4-dichlorophenol (2,4-DCP), is characterised via the individualised quantification of the products of the enzymatic reaction using a new methodology of HPLC-UV spectrometry. This innovation has allowed the discovery that, in addition to 13(2) OH chl a and 15(1) OH lactone chl a, which are the first products of POD on chl a, the reaction process sequentially creates another series of oxidised chlorophyll derivatives which have not been previously described. Their origins have been linked to POD activity in the presence of 2,4-DCP. Likewise, a study of the effect of the concentration of the various cosubstrates on the POD reaction rate demonstrated that the correct establishment of the relative concentrations of the same ([H2O2]/[2,4-DCP]/[Chl]=1:3:0.02) is crucial to explaining inhibition effects by substrates and carrying out optimum measurements. Therefore, new essential parameters for the determination of POD activity on a chlorophyll substrate are established. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Indonesia today is still a State agrarian. Thus agriculture in Indonesia always get more attention by the government. Many government programs are rolled out to support the agricultural development of Indonesia, and one of them is the fertilizer subsidy to farmers Indonesia. Fertilizer itself is very useful to nourish the soil and provide vitamins to the plants, thus increasing the amount of production generated. Therefore it is necessary fertilizer for agriculture in Indonesia. CV. G company is one of the companies that produce fertilizer. Fertilizer produced by this company is an organic fertilizer and inorganic fertilizer. Problems faced by these companies are in planning the production of fertilizer produced. Companies want to optimize the amount of production of each fertilizer, maximize revenues, minimize production costs, and simultaneously optimize the working hours of employees. To meet these objectives, this research created program package using goal programming methods. Goal programming method can provide an effective solution / equilibrium toward the goals set, and the calculation will be assisted by using the Simplex method that has been modified. This method is an extension of linear programming, linear programming which can only solve problems with a single goal while the goal programming to solve problems with multiple objectives.

    Mango pulp contains ascorbic acid, carotenoids, polyphenols, terpenoids and fiber which are healthy and could protect against colon cancer. The aim of this study was to evaluate the antiproliferative and preventive capacity of an aqueous extract of Mangifera indica cv. Azúcar on a human colon adenocarcinoma cell line (SW480) and in a rodent model of colorectal cancer, respectively. The content of total phenolics, flavonoids and carotenoids were also analyzed in the extract. SW480 cell growth was inhibited in a dose and time dependent manner by 22.3% after a 72h exposure to the extract (200 µg/ mL). Colon carcinogenesis was initiated in Balb/c mice by two intra-peritoneal injections of azoxymethane (AOM) at the third and fourth week of giving mango in drinking water (0.3%, 0.6%, 1.25%). After 10 weeks of treatment, in the colon of mice receiving 0.3% mango, aberrant crypt foci formation was inhibited more than 60% (p=0,05) and the inhibition was dose-dependent when compared with controls receiving water. These results show that mango pulp, a natural food, non toxic, part of human being diet, contains bioactive compounds able to reduce growth of tumor cells and to prevent the appearance of precancerous lesions in colon during carcinogenesis initiation.

    Transgenic plastids offer unique advantages in plant biotechnology, including high-level foreign protein expression. However, broad application of plastid genome engineering in biotechnology has been largely hampered by the lack of plastid transformation systems for major crops. Here we describe the development of a plastid transformation system for lettuce, Lactuca sativa L. cv. Cisco. The transforming DNA carries a spectinomycin-resistance gene (aadA) under the control of lettuce chloroplast regulatory expression elements, flanked by two adjacent lettuce plastid genome sequences allowing its targeted insertion between the rbcL and accD genes. On average, we obtained 1 transplastomic lettuce plant per bombardment. We show that lettuce leaf chloroplasts can express transgene-encoded GFP to approximately 36% of the total soluble protein. All transplastomic T0 plants were fertile and the T1 progeny uniformly showed stability of the transgene in the chloroplast genome. This system will open up new possibilities for the efficient production of edible vaccines, pharmaceuticals, and antibodies in plants.

    This paper describes the ST/EL and ST/CV services for TI2 & TI8 LHC injection tunnels. The cooling and ventilation part describes the requirements for design and installation of more than 10 km of pipeline that is going to be laid down in the tunnels. Main operating parameters as well as manufacture procedures are explained. Preliminary work schedule with the cost estimate is also presented. Electrical power will be distributed from the LHC side and the SPS side for the machine and the general services. All power converters will be installed on surface buildings. The link between the main bend converters and the main bend magnets will be realised with water-cooled cables. Rest of the magnets will be cabled by using conventional copper and aluminium cables. Due to long lengths of the injection tunnels a dry 18kV transformer will be installed in TJ8 to serve the general services for TI8. The same will apply to TI2 by installing a transformer at the bottom of the PMI2 shaft.

    Full Text Available An Agrobacterium-mediated transformation method was applied to introduce the luciferase reporter gene under the control of the CaMV35S promoter in the pGreen0049 binary vector into strawberry cv. Camarosa. The in vitro regeneration system of strawberry leaves to be used in the transformation was optimized using different TDZ concentrations in MS medium. TDZ at 16 µM showed the highest percentage (100% of shoot formation and the highest mean number of shoots (24 produced per explant. Studies on the effects of different antibiotics, namely timentin, cefotaxime, carbenicillin and ampicillin, on shoot regeneration of strawberry leaf explants showed the best shoot regeneration in the presence of 300 mg/L timentin and 150 mg/L cefotaxime. Assessment of the different factors affecting Agrobacterium mediated-transformation of strawberry with the luciferase gene showed the highest efficiency of putative transformant production (86% in the treatment with no preculture, bacterial OD600 of 0.6 and the addition of 150 mg/L cefotaxime in the pre-selection and selection media. The presence of the luciferase gene in the plant genome was verified by the luciferase reporter gene assay, nested PCR amplification and dot blot of genomic DNA isolated from the young leaves of each putatively transformed plantlet.

    The entire flower of Tulipa gesneriana cv. Murasakizuisho is purple, except the bottom, which is blue. To elucidate the mechanism of the different color development in the same petal, we prepared protoplasts from the purple and blue epidermal regions and measured the flavonoid composition by HPLC, the vacuolar pH by a proton-selective microelectrode, and element contents by the inductively coupled plasma (ICP) method. Chemical analyses revealed that the anthocyanin and flavonol compositions in both purple and blue colored protoplasts were the same; delphinidin 3-O-rutinoside (1) and major three flavonol glycosides, manghaslin (2), rutin (3) and mauritianin (4). The vacuolar pH values of the purple and blue protoplasts were 5.5 and 5.6, respectively, without any significant difference. However, the Fe(3+) content in the blue protoplast was approximately 9.5 mM, which was 25 times higher than that in the purple protoplasts. We could reproduce the purple solution by mixing 1 with two equimolar concentrations of flavonol with lambda(vismax) = 539 nm, which was identical to that of the purple protoplasts. Furthermore, addition of Fe(3+) to the mixture of 1-4 gave the blue solution with lambda(vismax) = 615 nm identical to that of the blue protoplasts. We have established that Fe(3+) is essential for blue color development in the tulip.

    Grapevine training systems determine the suitability for grape varieties in a specific growing region. We evaluated the influence of three training systems, Single Guyot (SG), Spur-pruned Vertical Shoot-Positioned (VSP), and Four-Arm Kniffin (4AK), on the performance of grapes and vines of Vitis vinifera L. cv. Cabernet Sauvignon in the 2012 and 2013 growing seasons in a wet region of central China. 4AK was the most productive system in comparison to SG and VSP. SG and VSP had lower disease infections of leaves and berries, especially in the mid- and final stage of berry ripening. Three training systems had no impact on berry maturity. PLS-DA (Partial Least Squares-Discriminant) analysis showed that the relatively dry vintage could well discriminate three training systems, but the wet vintage was not. A wet vintage of 2013 had more accumulation of 3'5'-substituted and acylated anthocyanins, including malvidin-3-O-(6-O-acetyl)-glucoside, malvidin-3-O-glucoside, and petunidin-3-O-(cis-6-O-coumaryl)-glucoside, etc. With regard to the effect of training systems, 4AK grapes had the lowest concentrations of total anthocyanins and individual anthocyanins, SG and VSP differed according to the different vintages, and showed highest concentration of total individual anthocyanins in 2012 and 2013, respectively. Generally, VSP benefited the most, contributing to significantly highest levels of total individual anthocyanins, and major anthocyanin, including malvidin-3-O-glucoside and malvidin-3-O-(6-O-acetyl)-glucoside, and the grapes obtained from VSP presented significantly highest proportion of 3'5'-substituted anthocyanins. With regard to the ratios of 3'5'/3'-substituted, methoxylated/non-methoxylated and acylated/non-acylated anthocyanins, the significantly higher levels were also shown in VSP system. In summary, VSP was the best training system for Cabernet Sauvignon to accumulate relatively stable individual anthocyanins in this wet region of China and potentially in

    Three tau class MaGSTs responded to abiotic stress, MaGSTF1 and MaGSTL1 responded to signaling molecules, they may play an important role in the growth of banana plantlet. Glutathione S-transferases (GST) are multifunctional detoxification enzymes that participate in a variety of cellular processes, including stress responses. In this study, we report the molecular characteristics of five GST genes (MaGSTU1, MaGSTU2, MaGSTU3, MaGSTF1 and MaGSTL1) cloned from banana (Musa acuminate L. AAA group, cv. Cavendish) using a RACE-PCR-based strategy. The predicted molecular masses of these GSTs range from 23.4 to 27.7 kDa and their pIs are acidic. At the amino acid level, they share high sequence similarity with GSTs in the banana DH-Pahang (AA group) genome. Phylogenetic analysis showed that the deduced amino acid sequences of MaGSTs also have high similarity to GSTs of other plant species. Expression analysis by semi-quantitative RT-PCR revealed that these genes are differentially expressed in various tissues. In addition, their expression is regulated by various stress conditions, including exposure to signaling molecules, cold, salinity, drought and Fusarium oxysporum f specialis(f. Sp) cubense Tropical Race 4 (Foc TR4) infection. The expression of the tau class MaGSTs (MaGSTU1, MaGSTU2 and MaGSTU3) mainly responded to cold, salinity and drought while MaGSTF1 and MaGSTL1 expressions were upregulated by signaling molecules. Our findings suggest that MaGSTs play a key role in both development and abiotic stress responses.

    To understand the molecular mechanisms that control seed formation, we selected a seed-preferential gene (CvADH1) from the ESTs of developing watermelon seeds. RNA blot analysis and in situ localization showed that CvADH1 was preferentially expressed in the nucellar tissue. The CvADH1 protein shared about 50% homology with short-chain alcohol dehydrogenase including ABA2 in Arabidopsis thaliana, stem secoisolariciresinol dehydrogenase in Forsythia intermedia, and 3beta-hydroxysterol dehydrogenase in Digitalis lanata. We investigated gene-expression levels in seeds from both normally pollinated fruits and those made parthenocarpic via N-(2-chloro-4-pyridyl)-N'-phenylurea treatment, the latter of which lack zygotic tissues. Whereas the transcripts of CvADH1 rapidly started to accumulate from about the pre-heart stage in normal seeds, they were not detectable in the parthenocarpic seeds. Treating the parthenogenic fruit with GA(3) strongly induced gene expression, up to the level accumulated in pollinated seeds. These results suggest that the CvADH1 gene is induced in maternal tissues by signals made in the zygotic tissues, and that gibberellin might be one of those signals. We also observed that CvADH1 expression was induced by sucrose in the parthenocarpic seeds. Therefore, we propose that the CvADH1 gene is inducible by gibberellin, and that sucrose plays an important role in the maternal tissues of watermelon during early seed development.

    Full Text Available Plantas micropropagadas geralmente apresentam dificuldades de adaptação ao meio ex vitro, sendo muitas vezes submetidas a processos de rustificação para minimizar os impactos decorrentes da mudança de ambiente. Uma vez que a folha e seus anexos destacam-se como importantes indicativos das estratégias adaptativas das plantas a ambientes adversos, este trabalho teve por objetivo comparar a anatomia foliar de plantas de abacaxi cv. IAC "Gomo-de-mel" cultivadas in vitro com microplantas aclimatizadas em diferentes condições de luminosidade, sob telado com 50% de sombreamento e em pleno sol para verificar a necessidade do processo de rustificação para este cultivar. Avaliações por meio de microscopia de luz e eletrônica de varredura da epiderme foliar, demonstraram aumento na densidade de escamas em ambas as superfícies das folhas, em microplantas dos ambientes ex vitro, principalmente em relação às que foram expostas diretamente ao sol. Observou-se ainda, aumento no espessamento da cutícula, na sinuosidade das células epidérmicas, e na distribuição e quantidade de fibras no mesofilo evidenciando a interferência das condições de luminosidade nas características morfológicas das microplantas. Essas alterações não prejudicaram o desenvolvimento das microplantas, indicando que não são necessárias etapas de rustificação para a aclimatização deste cultivar.Microprapagated plants usually show difficulties to adapt to ex vitro conditions, and many times are submitted to the rustication process to aim the reduction of all the impacts resulting from the environmental changes. Once the leaf and its annexes are important indicators of adaptability strategies of the plants to adverse environmental conditions, the objective of this work was to compare the leaf anatomy of pineapple cv. IAC "Gomo-de-mel" in vitro cultivated plants with microplants acclimatized in different conditions of luminosity, under mesh, with 50 % of

    Vibroarthrography, a method for interpreting the sounds emitted by a knee during movement, has been studied for several joint disorders since 1902. However, to our knowledge, the usefulness of this method for management of Juvenile Idiopathic Arthritis (JIA) has not been investigated. To study joint sounds as a possible new biomarker for pediatric cases of JIA we designed and built VibroCV, a platform to capture vibroarthrograms from four accelerometers; electromyograms (EMG) and inertial measurements from four wireless EMG modules; and joint angles from two Sony Eye cameras and six light-emitting diodes with commercially-available off-the-shelf parts and computer vision via OpenCV. This article explains the design of this turn-key platform in detail, and provides a sample recording captured from a pediatric subject.

    Powdery mildew is a prevalent fungal disease affecting oat (Avena sativa L.) production in Europe. Common oat cultivar Rollo was previously shown to carry the powdery mildew resistance gene Eg-3 in common with cultivar Mostyn. The resistance gene was mapped with restriction fragment length polymorphism (RFLP) markers from Triticeae group-1 chromosomes using a population of F(3) lines from a cross between A. byzantina cv. Kanota and A. sativa cv. Rollo. This comparative mapping approach positioned Eg-3 between cDNA-RFLP marker loci cmwg706 and cmwg733. Since both marker loci were derived from the long arm of barley chromosome 1H, the subchromosomal location of Eg-3 was assumed to be on the long arm of oat chromosome 17. Amplified fragment length polymorphism (AFLP) marker technology featured as an efficient means for obtaining markers closely linked to Eg-3.

Nevertheless, the medical field is very wide, so for detecting diseases problems, not yet much disease that detection can be done with a computer-based system. One example of the issues is well-known disease detection, which is malaria. Malaria is classified as a serious disease because it can cause death if it is not treated properly. Malaria has various types and can affect anyone anywhere. The symptoms of malaria is really common as it may appear in daily life, but cannot always indicate that a person infected with malaria. Indications, which can show that a person infected with malaria, are the clinical examination and blood tests.With the blood test, the treatment of malaria can be implemented correctly and precisely. It needs technology that can detect malaria correctly and precisely. The solution is the method of support vector machine that can detect malaria in humans by viewing image of appearance blood cells.METHODThe methods used in this research are data collection, analysis and design.
