    A reproducible and efficient transformation method was developed for the banana cv. Rasthali (AAB) via Agrobacterium-mediated genetic transformation of suckers. Three-month-old banana suckers were used as explant and three Agrobacterium tumefaciens strains (EHA105, EHA101, and LBA4404) harboring the binary vector pCAMBIA1301 were used in the co-cultivation. The banana suckers were sonicated and vacuum infiltered with each of the three A. tumefaciens strains and co-cultivated in the medium containing different concentrations of acetosyringone for 3 days. The transformed shoots were selected in 30 mg/l hygromycin-containing selection medium and rooted in rooting medium containing 1 mg/l IBA and 30 mg/l hygromycin. The presence and integration of the hpt II and gus genes into the banana genome were confirmed by GUS histochemical assay, polymerase chain reaction, and southern hybridization. Among the different combinations tested, high transformation efficiency (39.4 ± 0.5% GUS positive shoots) was obtained when suckers were sonicated and vacuum infiltered for 6 min with A. tumefaciens EHA105 in presence of 50 μM acetosyringone followed by co-cultivation in 50 μM acetosyringone-containing medium for 3 days. These results suggest that an efficient Agrobacterium-mediated transformation protocol for stable integration of foreign genes into banana has been developed and that this transformation system could be useful for future studies on transferring economically important genes into banana.

    No presente trabalho procurou-se determinar a causa da “seca do cacho” de banana do cultivar Prata (Musa sp. AAB e analisar alguns aspectos de sua ocorrência no Estado de Goiás. A doença afeta drasticamente a produção, e ocorre mais severamente durante o período chuvoso (outubro - abril, podendo, em certas regiões, afetar quase todos os cachos. Mediante os resultados obtidos em isolamentos sob condições axênicas e através da aplicação do postulado de Koch, determinou-se que a causa primária da doença á o fungo Gloeosporium musarum Cooke & Massee, atuando sob condições climáticas predisponentes. Foi sugerido que características clonais, condições climáticas e potencial de inóculo disponível sejam os principais fatores envolvidos na distribuição regional da enfermidade.

    The purpose of the present study was to determine the cause of the drying of the bunch in the “Prata banana” (Musa sp. AAB and to analyze some of the aspects of its occurrence in the State of Goiás. The disease drastically affects production, and occurs more severely during the rainy season (October to April , going so far as to affect almost all of the bunches in certain regions. Based on the results obtained in isolation, under aseptic conditions, and using Koch’s postulate, the primary cause of the disease was determined to be the fungus Gloesporium musarum Cooke & Massee, which acts under predisposing climatic conditions. It was suggested that clonal characteristics, climatic conditions, and the potential of available innoculum were the principal factors involved in the spread of the disease in certain regions.

    Shoot tips and in vitro grown proliferating buds of banana cv. Rasthali (Silk, AAB) were treated with various concentrations and durations of chemical mutagens viz., EMS, NaN3 and DES. LD50 for shoot tips based on 50% reduction in fresh weight was determined as 2% for 3 h, 0.02% for 5 h and 0.15% for 5 h, while for proliferating buds, they were 0.6% for 30 min, 0.01% for 2 h and 0.06% for 2 h for the mutagens EMS, NaN3 and DES, respectively. Subsequently, the mutated explants were screened in vitro against fusarium wilt using selection agents like fusaric acid and culture filtrate. LD50 for in vitro selection agents calculated based on 50% survival of explants was 0.050 mM and 7% for fusaric acid and culture filtrate, respectively and beyond which a rapid decline in growth was observed. This was followed by pot screening which led to the identification of three putative resistant mutants with an internal disease score of 1 (corm completely clean, no vascular discolouration). The putative mutants identified in the present study have also been mass multiplied in vitro.

    2016-06-01

    The tight-binding model and gradient approximation are, respectively, used to calculate the band structures and the absorption spectra of AAB-stacked trilayer graphene (AAB-TLG). AAB stacking, the lowest symmetric geometric structure in trilayer systems, induces the most atomic interactions, and thus, complicates the energy dispersions and the joint density of states. AAB stacking enriches the optical absorption spectra [A(ω)], which dictate the characteristics of the electronic structure. A(ω) are changed by the static electric field, such as the intensity, frequency, and number of absorption structures. These results contrast sharply with those for TLG in other stacking configurations.

    2015-01-01

    The generalized tight-binding model is developed to investigate the feature-rich magneto-optical properties of AAB-stacked trilayer graphene. Three intragroup and six intergroup inter-Landau-level (inter-LL) optical excitations largely enrich the magneto-absorption peaks. In general, the former are much higher than the latter, depending on the phases and amplitudes of LL wavefunctions. The absorption spectra exhibit the single- or twin-peak structures which are determined by the quantum modes, LL energy spectra and Fermion distribution. The splitting LLs, with different localization centers (2/6 and 4/6 positions in a unit cell), can generate very distinct absorption spectra. There exist extra single peaks because of LL anticrosings. AAB, AAA, ABA, and ABC stackings quite differ from one another in terms of the inter-LL category, frequency, intensity, and structure of absorption peaks. The main characteristics of LL wavefunctions and energy spectra and the Fermi-Dirac function are responsible for the configur...

    One of the most severe viral diseases of hill banana is caused by banana bunchy top virus (BBTV), a nanovirus transmitted by the aphid Pentalonia nigronervosa. In this study, we reported the Agrobacterium-mediated transformation on a highly valued hill banana cultivar Virupakshi (AAB) for resistance to BBTV disease. The target of the RNA interference (RNAi) is the rep gene, encoded by the BBTV-DNA1. In order to develop RNAi construct targeting the BBTV rep gene, the full-length rep gene of 870 bp was polymerase chain reaction amplified from BBTV infected hill banana sample DNA, cloned and confirmed by DNA sequencing. The partial rep gene fragment was cloned in sense and anti sense orientation in the RNAi intermediate vector, pSTARLING-A. After cloning in pSTARLING-A, the cloned RNAi gene cassette was released by NotI enzyme digestion and cloned into the NotI site of binary vector, pART27. Two different explants, embryogenic cells and embryogenic cell suspension derived microcalli were used for co-cultivation. Selection was done in presence of 100 mg/L kanamycin. In total, 143 putative transgenic hill banana lines were generated and established in green house condition. The presence of the transgenes was confirmed in the selected putative transgenic hill banana lines by PCR and reverse transcription PCR analyses. Transgenic hill banana plants expressing RNAi-BBTV rep were obtained and shown to resist infection by BBTV. The transformed plants are symptomless, and the replication of challenge BBTV almost completely suppressed. Hence, the RNAi mediating resistances were shown to be effective management of BBTV in hill banana.

    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.

    Full Text Available La cuenca Neuquina se localiza en el sector centro-oeste de Argentina, constituyendo el depocentro mesozoico-neogeno más importante y una de las cuencas del hemisferio sur con excelente registro marino y continental. La evolución de la cuenca Neuquina se encuentra caracterizada por tres estadios de evolución: una etapa inicial de rift; subducción relacionada a un sag termal y un estadio de cuenca de antepaís. El Subgrupo Río Colorado es depositado en la cuenca durante el desarrollo de la etapa de antepaís. La tectónica sindepositacional del subgrupo es registrada por tres niveles deformados, dos en la Formación Bajo de Carpa y uno en la Formación Anacleto. Los mismos están integrados por estructuras de deformación y licuefacción interpretadas como sismitas. La deformación está representada por estructuras de carga simple, bolas y cogines, flamígeras, pseudonódulos, laminación convoluta, pinch and swell, slumps, areniscas desorganizadas, areniscas replegadas, diapiros de fango, fracturas, dish and pillar y brechas autoclásticas. Estas deformaciones en la Formación Bajo de la carpa involucra depósitos de cinturones de canal y de planicie de inundación; mientras que en la Formación Anacleto afecta a los depósitos de canales de mareas de alta y baja sinuosidad; planicies intermareal fango-arenosa y planicie fangosa supramareal, asociados a un sistema estuárico medio. Los niveles de sísmitas reconocidos podrían estar asociados al lineamiento Lindero Atravesado y Sierra Barrosa y ser una respuesta dinámica a la actividad de dichas es-tructuras. La naturaleza de las estructuras y su distribución sugiere que la magnitud de los sismos podría ser mayor a 6 en escala de Ritcher en el Mesozoico.

  18. CV controls from design to operation

    2002-01-01

    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 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 differential rotation and effects on the disk by the accretion stream must be addressed. Our a...

    We present Keck/NIRC2 and OSIRIS near-infrared imaging and spectroscopy of 2M0441+2301 AabBab, a young (1-3 Myr) hierarchical quadruple system comprising a low-mass star, two brown dwarfs, and a planetary-mass companion in Taurus. All four components show spectroscopic signs of low surface gravity, and both 2M0441+2301 Aa and Ab possess Paβ emission indicating they each harbor accretion subdisks. Astrometry spanning 2008-2014 reveals orbital motion in both the Aab (0.″23 separation) and Bab (0.″095 separation) pairs, although the implied orbital periods of >300 years mean dynamical masses will not be possible in the near future. The faintest component (2M0441+2301 Bb) has an angular H-band shape, strong molecular absorption (VO, CO, H2O, and FeH), and shallow alkali lines, confirming its young age, late spectral type (L1 ± 1), and low temperature (≈1800 K). With individual masses of {200}-50+100 MJup, 35 ± 5 MJup, 19 ± 3 MJup, and 9.8 ± 1.8 MJup, 2M0441+2301 AabBab is the lowest-mass quadruple system known. Its hierarchical orbital architecture and mass ratios imply that it formed from the collapse and fragmentation of a molecular cloud core, demonstrating that planetary-mass companions can originate from a stellar-like pathway analogous to higher-mass quadruple star systems as first speculated by Todorov et al. More generally, cloud fragmentation may be an important formation pathway for the massive exoplanets that are now regularly being imaged on wide orbits. The data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation.

    When metal/semiconductor schotky barriers are not practical, an electrolyte/semiconductor interface can be used to make capacitance-voltage (C-V) measurements. The physics of such electrochemical C-V measurements will be described. Electrical properties of ZnO were measured by electrochemical C-V techniques and photovoltage spectroscopy using an Accent 4400 Electrochemical CV system. Specifically, the electrical behavior of a 0.1 M ZnCl2 electrolyte-ZnO interface has been investigated with attention to the electrolyte-ZnO interface's C-V dependence on carrier frequency.

Em continuidade, o presente trabalho estudou características físicas e morfológicas dos grânulos de amido de ambas as espécies de banana comparando-as com amido nativo de milho comercial. O amido de bananas foi extraído segundo CHIANG, CHU & CHU [3]. A morfologia dos grânulos foi realizada após tratamento enzimático in vitro a 37°C/24h com alfa-amilase pancreática. Foram efetuados os respectivos amilogramas e difractogramas de raios-X. Os grânulos de amido da Musa Tipo AAA-Nanicão apresentaram comprimento entre 30-40µm. Em Musa AAB-Terra, os grânulos, também ovais e alongados, eram um pouco menores, 20-30µm. A corrosão enzimática in vitro iniciava-se sobre a superfície anteriormente lisa e formavam estrias superficiais e apicais. A Microscopia Eletrônica de Varredura (MEV mostrou que a hidrólise in vitro por 24 horas foi pequena e ocorria sobretudo nas camadas amorfas dos grânulos de ambas as espécies. O padrão de corrosão demonstrou-se distinto daquele ocorrido no amido de milho. As suspensões de amido de bananas ao viscosímetro demonstraram forte capacidade de hidratação e menor capacidade de retrogradação em relação ao milho, sobretudo do amido de Musa Tipo AAA-Nanicão; o amido de Musa Tipo AAB-Terra apresentou maior estabilidade de pasta. Na análise de difração de raios-X, os grânulos de bananas apresentaram padrão tipo B e C para Musa Tipo AAA-Nanicão e Musa Tipo AAB-Terra, respectivamente. Conclui-se que os amidos de Musa AAA-Nanicão e Musa AAB-Terra são estruturalmente distintos, justificando as respostas fisiológicas distintas encontradas posteriormente pelos mesmos autores.

    2003-01-01

    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...

    Le bureau d’études CV, au même titre que les autres bureaux d’études du CERN, est étroitement lié au déroulement du projet LHC. Dans ce contexte, l’adaptation devient une dimension essentielle pour assurer des prestations organisées et efficaces. En effet, la rentabilité, l’optimisation des ressources, la stratégie de sous-traitance, les contraintes imposées par la coordination générale LHC et la charge de travail diminuant vers la fin du projet, sont autant que facteurs qui influencent son organisation. L’analyse des expériences multiples et l’évaluation du risque organisationnel permettent de repositionner méthodiquement la structure face au changement, notamment pour l’horizon 2007. Le bureau d’études CV converge déjà vers une distribution « bimodale » : tandis que les tâches proches de la coordination restent confiées à un bureau interne réduit au strict minimum, une part grandissante des tâches est sous-traitée à des mandataires extérieurs.

    The present study was carried out on a sample of 125 right-handed boys who are described as follows: 50 boys with dyslexia, 50 controls of a similar age, and 25 controls according to reading level. Using an objective procedure based on regression, we selected three subgroups from among the poor readers: children with difficulties in the lexical pathway (surface dyslexics), children with difficulties in the sublexical pathway (phonological dyslexics), and children with problems in both pathways (mixed dyslexics). When the performances of these children on a dichotic listening task with CV syllables as stimuli were compared, it was found that although the children with dyslexia obtained lower lateralization indices than did the controls, the differences were only clearly significant when the most severe cases of phonological dyslexia were selected.

La presente contribución da a conocer los resultados del análisis sedimentológico y paleoambiental de las Formaciones Bajo de la Carpa (Santoniano y Anacleto (Campaniano inferior. Los estudios llevados a cabo permitieron definir cuatro litofacies conglomerádicas, nueve de areniscas y dos pelíticas, que fueron agrupadas en nueve asociaciones de litofacies, dos de ellas de origen eólico y siete fluviales. La Formación Bajo de la Carpa está representada en la base por un sistema fluvial efímero, y en el techo por depósitos de interacción fluvio- eólica. Los depósitos fluviales corresponden a flujos canalizados durante episodios de máxima descarga. Luego se identifica un campo de dunas transversales, afectado en el subambiente de interduna por corrientes fluviales efímeras, y dunas parabólicas producto de la removilización del sistema eólico infrayacente, asociadas con depósitos de flujos efímeros en manto. La extensión y geometría de los campos de dunas respondieron a variaciones climáticas de corto término, interferencia del sistema fluvial, oscilaciones del nivel freático, bajo suministro y/o disponibilidad de sedimentos y factores tectónicos. La Formación Anacleto presenta en su base sistemas fluviales de baja sinuosidad, alta energía y rápida agradación, controlados por un bajo espacio de acomodación y condiciones climáticas con marcada estacionalidad. Hacia el tope se identifica un sistema fluvial anastomosado que refleja variaciones climáticas y aumento de la tasa de subsidencia acompañada de un lento ascenso del nivel de base relacionado con la ingresión atlántica maastrichtiana.

    CV247 (CV), an aqueous mixture of copper (Cu) and manganese (Mn) gluconates, vitamin C and sodium salicylate increased the antitumour effects of cisplatin (CDPP; cis-diamminedichloroplatinum) in vitro. We hypothesized that the antioxidant and cyclooxygenase-2 (COX-2; prostaglandin-endoperoxide synthase 2) inhibitory components of CV can protect the kidneys from CDPP nephrotoxicity in rats. CDPP (6.5 mg/kg, intraperitoneally) slightly elevated serum creatinine (Crea) and blood urea nitrogen (BUN) 12 days after treatment. Kidney histology demonstrated extensive tubular epithelial damage and COX-2 immunoreactivity increased 14 days after treatment. A large amount of platinum (Pt) accumulated in the kidney of CDPP-treated rats. Furthermore, CDPP decreased renal iron (Fe), molybdenum (Mo), zinc (Zn), Cu and Mn concentrations and increased plasma Fe and Cu concentrations. CDPP elevated plasma free radical concentration. Treatment with CV alone for 14 days (twice 3 ml/kg/day orally) did not influence these parameters. Chronic CV administration after CDPP reduced renal histological damage and slightly decreased COX-2 immunoreactivity, while failed to prevent the increase in Crea and BUN levels. Blood free radical concentration was reduced, that is, CV improved redox homeostasis. CV restored plasma Fe and renal Fe, Mo and Zn, while decreased Pt and elevated Cu and Mn concentrations in the kidney. Besides the known synergistic antitumour effects with CDPP, CV partially protected the kidneys from CDPP nephrotoxicity probably through its antioxidant effect.

    Full Text Available On two plantations of first harvest of Musa AAB each consisting of separate lots of False Horn Plantain (Semi-Giant and Dwarf nematode populations were determined in plants with one to three days flowering and in their respective succeeding suckers. The objective was to determine if there is a relationship between the nematode population in mother plants and their succeeding suckers. Sixty and twenty plants of each cultivar were evaluated in Pococí (70 masl and Matina (40 masl locations, respectively. Nematodes were extracted by maceration of the roots, pouring the suspension through a series of 0.5/0.150/0.038 mm (N° 30/100/400 mesh sieves nested together with the 0.5 mm on top. Populations levels were expressed per 100 g of roots. The results showed no linear relationship between the nematode populations of the flowering plants and their succeeding sucker. Although the differences were not statistically significant, the densities of R. similis determined in flowering plants tended in most cases to overestimate the populations in the succeeding suckers. Sampling flowering plants at Pococí (70 masl overestimated Helicotylenchus spp. populations in the succession suckers of both cultivars, while those at Matina (40 masl were underestimated. The estimation of Meloidogyne spp. and Pratylenchus spp. populations was also not reliable. To decide on nematicide applications, it is recommended to sample the succeeding suckers of recently flowering plants.

    To observe the specific brain effects of electroacupuncture (EA) stimulation of Guanyuan (CV 4) and Zhongwan (CV 12). Twenty-one healthy volunteers were recruited in the present study. Two silver filiform needles were separately inserted into Guanyuan (OV 4) or Zhongwan (CV 12), and manipulated with uniform reducing-reinforcing method to induce "Deqi". fMRI scan was performed before needling, during needle retention, EA stimulation, and post-EA. Data of fMRI was analyzed by using software SPM 2. The volunteer subjective needling sensations were recorded. The activation, deactivation, short-distance and long-distance functional connectivity maps of different cerebral regions were analyzed by using whole brain correlation analysis. Comparison between the two acupoints showed that fullness feeling was stronger in CV 4 than in CV 12. EA at CV 4 and CV 12 induced a similar stronger and prevalent deactivation in the ventral medial prefrontal cortex and the anterior cingulated cortex (ACO). The deactivation of the ACC was stronger in the CV 4 group than in the CV 12 group. The default BOLD mode of the brain at rest was modified by needle retention and EA, respectively. The short-distance functional connection brain network was significantly changed after EA. Interestingly, the ventral medial prefrontal cortex and anteroinferior portion of the anterior cingulate cortex in the limbic-paralimbic-neocortical network (LPNN) were involved in the instant post-effects of EA. Relatively smaller differences in the brain functional activity and short-distance functional connectivity were found between these two acupoints. EA of CV 4 and CV 12 can modulate short-distance functional connectivity of the LPNN, and have fewer differences in inducing needling sensation and deactivation of ACC, etc.

  15. Graphite whiskers in CV3 meteorites.

    Fries, Marc; Steele, Andrew

    2008-04-04

    Graphite whiskers (GWs), an allotrope of carbon that has been proposed to occur in space, have been discovered in three CV-type carbonaceous chondrites via Raman imaging and electron microscopy. The GWs are associated with high-temperature calcium-aluminum inclusion (CAI) rims and interiors, with the rim of a dark inclusion, and within an inclusion inside an unusual chondrule that bears mineralogy and texture indicative of high-temperature processing. Current understanding of CAI formation places their condensation, and that of associated GWs, relatively close to the Sun and early in the condensation sequence of protoplanetary disk materials. If this is the case, then it is a possibility that GWs are expelled from any young solar system early in its history, thus populating interstellar space with diffuse GWs. Graphite whiskers have been postulated to play a role in the near-infrared (near-IR) dimming of type Ia supernovae, as well as in the thermalization of both the cosmic IR and microwave background and in galactic center dimming between 3 and 9 micrometers. Our observations, along with the further possibility that GWs could be manufactured during supernovae, suggest that GWs may have substantial effects in observational astronomy.

    Early Solar System planetesimal thermal models predict the heating of the chondritic protolith and the preservation of a chondritic crust on differentiated parent bodies. Petrological and geochemical analyses of chondrites have suggested that secondary alteration phases formed at low temperatures (hydrothermal fluid. Putative 'onion shell' structures are not anymore a requirement for the CV parent body crust.Meteorites may unlock the history of the early solar system. Here, the authors find, through Ca-Fe-rich secondary phases, that the distinction between reduced and oxidized CV chondrites is invalid; therefore, CV3 chondrites are asteroid fragments that percolated heterogeneously via porous flow of hydrothermal fluid.

En esta área se llevaron a cabo estudios sedimentológicos con el objeto de determinar los paleoambientes de sedimentación y su evolución, como así también establecer los controles auto y alocíclicos más relevantes. Se definieron doce facies que fueron incluidas en seis asociaciones de facies. La naturaleza y la geometría de las asociaciones de facies sugieren el desarrollo de sistemas fluviales de baja sinuosidad, entrelazados y anastomosados, como así también dunas y mantos de arena eólicos. Los sistemas fluviales estuvieron sujetos a cambios en el régimen de descarga que se interpretan relacionados a variaciones climáticas de corto término. Las variaciones en el tamaño de grano dominante de la carga de lecho, el espesor de los cuerpos de canal y las variaciones relativas de la relación canales/planicie de inundación, responden a fluctuaciones en la descarga de más largo término. Las modificaciones en la arquitectura a gran escala también se interpretan relacionados a cambios en el nivel de base estratigráfico. En la base de la Formación Portezuelo los canales son espesos, muestran diseño entrelazado, albardones, depósitos de desborde y desarrollan una fuerte relación multilateral. Esta relación de las unidades de canal está relacionada con una tasa de suministro que, en general, es compensada por la tasa subsidencia. En los sectores distales de la planicie de inundación se desarrollan dunas y mantos eólicos. Gradualmente se registra una disminución en la relación canales/planicie de inundación.

    The competing effects resulting from the exposure of fruits of 'warf prata' banana (Musa acuminata x Musa balbisiana, AAB group) to gamma radiation and to calcium carbide have been investigated in this work. The fruits were harvested in a pre-climateric stage (green colored though physiologically developed) in the city of Jaiba, state of Minas Gerais, and gamma irradiated with doses of 0.25 or 0.50 kGy in a research irradiating facility at the Brazilian Army Technology Center (CTEx) in the city of Rio de Janeiro. Some samples were also exposed to calcium carbide for 32 hours in order to accelerate ripening. Quantitative estimates of peel color, disease index and fresh mass loss were performed for 9 days while the fruits were kept at an average temperature of 23 deg C. The analyses were performed in the Federal Rural University of Rio de Janeiro, located in the city of Seropedica. The following treatments or combination of processes have been tested: untreated (control); treated only with irradiation with doses of 0.25 kGy or 0.50 kGy; treated with irradiation with doses of 0.25 kGy or 0.50 kGy and then exposed to calcium carbide. The fruits treated solely with irradiation with 0.25 kGy exhibited a better response during the first days of storage, although their initial green coloration vanished with time. In addition, the fungi Colletotrichum musae and Lasidioplodia theobroma were detected in samples submitted to the combination of both processes. In contrast, such fungi were not observed in fruits that had only been exposed to 0.25 kGy and exhibited low disease indices. Also, 1-2 cm lesions were detected on fruits.(author)

    Banana is a highly perishable climacteric fruit. In order to ensure fast and homogeneous ripening that will make its processing and commercialization easier, it is usually treated by climatization. On the other hand, irradiation is an interesting physical process capable of delaying ripening and extending the shelf life of fruits. This work investigated the competing effects of irradiation followed by climatization on the quality of 'Prata' banana (Musa acuminata x Musa balbisiana, AAB). All fruits were harvested in the preclimacteric stage, rinsed and stored at 27 deg C after being submitted to five different treatments. After hygienization, four out of five samples were exposed to gamma-ray at doses of 0.25 and 0.50 kGy. The unirradiated fruits were left for control and half of the irradiated samples were then climatized by exposure to CaC{sub 2}. Measurements of fresh mass loss, total soluble solids, peel coloration and disease index were performed on five different dates for up to nine days in order to monitor quality and the degree of ripening. It was found that high temperatures prevailing during climatization and storage accelerated maturation in all fruits in spite of the use of irradiation, with the control becoming ripe in 3 days only. In addition, based on the consistent results from the experiments performed, it can be concluded that irradiation at the doses tested was unable to overcome the maturation effects produced by climatization. However, the sole use of irradiation with 0.25 kGy yielded the lowest figures for fresh mass loss and disease index in the samples, thus becoming the most attractive among the treatments tested.

    Replicating the multi-hierarchical self-assembly of collagen (peptide chain to triple helix to nanofiber and, finally, to a hydrogel) has long attracted scientists, both from the fundamental science perspective of supramolecular chemistry and for the potential biomedical applications perceived in tissue engineering. In terms of triple helical formation, collagen is the most abundant protein in the human body with at least 28 types, yet research involving collagen mimetic systems has only recently began to consider the innate ability of collagen to control helix composition and register. Collagen triple helices can be homotrimeric or heterotrimeric and while some types of natural collagen form only one specific composition of helix, others can form multiple. It is critical to fully understand and, if possible, reproduce the control that native collagen has on helix composition and register. In terms of nanofiber formation, many approaches to drive the self-assembly of synthetic systems through the same steps as natural collagen have been partially successful, but none have simultaneously demonstrated all levels of structural assembly. In this work, advancements in the ability to control helix composition and replicate the multi-hierarchical assembly of collagen are described. Both positive and negative design for the assembly of AAB type collagen heterotrimers were utilized by promoting heterotrimer formation though the use of charged amino acids to form intra-helix electrostatic interactions, while simultaneously discouraging homotrimers, resulting in the identification of multiple peptide systems with full control over the composition of the resulting triple helix. Similar salt-bridged hydrogen bonds between charged residues were incorporated into nanofiber forming peptides, one of which successfully assembled into sticky-ended triple helices, nanofibers with characteristic triple helical packing visible in the solution state, and strong hydrogels that are

    Full Text Available Plantain cultivar 'FHIA – 25' (AAB shows high yielding qualities and high resistance to Black Sigatoka disease, but its sugar content in the fruit is low, so a regeneration method at cell level is necessary, such as somatic embryogenesis supported by biotechnological tools to improve fruit quality. This work was performed with the aim of establishing a plant regeneration method via somatic embryogenesis using initial explants of shoot apices from axillary buds in liquid culture medium. Homogenous embryogenic cell suspensions were obtained from mentioned explants. The highest cellular multiplication rates were achieved at 3,0% density. The incubation of somatic embryos during 30 days in the maturation culture medium permitted to increase germination. During the acclimatization stage, plants regenerated from somatic embryos, as well as plants from organogenesis, showed a high survival percentage (98 and 97 respectively, without somaclonal variation.

    The pseudorapidity density (dN/deta) for p+p, p+A and A+A(B) collisions, and the mean multiplicity for ee, ep, and p+p collisions, are studied for an inclusive range of beam energies (Root_s). Characteristic scaling patterns are observed for both dN/deta and , consistent with a thermal particle production mechanism for the bulk of the soft particles produced in all of these systems. They also validate an essential role for quark participants in these collisions. The scaled values for dN/deta and are observed to factorize into contributions which depend on log(Root_s) and the number of nucleon or quark participant pairs (Npp). Quantification of these contributions give expressions which serve to systematize dN/deta and measurements spanning nearly four orders of magnitude in Root_s, and to predict their values as a function of Root_s and Npp.

    Japanese encephalitis chimeric virus vaccine (JE-CV) is a licensed vaccine indicated in a single dose administration for primary immunization. This controlled phase III comparative trial enrolled children aged 36-42 mo in the Philippines. 345 children who had received one dose of JE-CV in a study two years earlier, received a JE-CV booster dose. 105 JE-vaccine-naïve children in general good health were randomized to receive JE-CV (JE-vaccine naïve group; 46 children) or varicella vaccine (safety control group; 59 children). JE neutralizing antibody titers were assessed using PRNT50. Immunological memory was observed in children who had received the primary dose of JE-CV before. Seven days after the JE-CV booster dose administration, 96.2% and 66.8% of children were seroprotected and had seroconverted, respectively, and the geometric mean titer (GMT) was 231 1/dil. Twenty-eight days after the JE-CV booster dose seroprotection and seroconversion were achieved in 100% and 95.3% of children, respectively, and the GMT was 2,242 1/dil. In contrast, only 15.4% of JE-CV-vaccine naïve children who had not received any prior JE vaccine were seroprotected seven days after they received JE-CV. One year after receiving the JE-CV booster dose, 99.4% of children remained seroprotected. We conclude that JE-CV is effective and safe, both as a single dose and when administrated as a booster dose. A booster dose increases the peak GMT above the peak level reached after primary immunization and the antibody persistence is maintained at least one year after the JE-CV booster dose administration. Five year follow up is ongoing.

    Full Text Available Computer vision is very progressive and modern part of computer science. From scientific point of view, theoretical aspects of computer vision algorithms prevail in many papers and publications. The underlying theory is really important, but on the other hand, the final implementation of an algorithm significantly affects its performance and robustness. For this reason, this paper tries to compare real implementation of tracking algorithms (one part of computer vision problem, which can be found in the very popular library OpenCV. Moreover, the possibilities of optimizations are discussed.

    Full Text Available Production Management is the act of designing, operating, and improving the productive systems – a system for getting the work done. Along the process, the synergy in between machineries, facilities and people could empower the sustainable of the production. In fact, for some cases, the implementation of unique system is needed for the production process. The example for this transformation production management is in the case of CV Wiracana, a handmade manufacturing company for folding hand fans from Bali. CV Wiracana's products are very unique, combined from mass production for the speed and an art for the custom made product. At one side, the market forces them to speed up the production and for this purpose, they must set up the new system on their production line. On the other side, the masterpiece also needs to be produced without jeopardizing mass production line schedule. The transformation production system needs to be done no later than 2015 as the urgency to fulfill the customer demand, business growth, compete in the industry and sustainability. The changes are expected to improve the production at least about 20% or doubled from the current production.

    Full Text Available Herbs are used in traditional medicine. There are so many herbs are spread across the world, it is difficult to memorize it all. This paper describes an android application to recognize herbs by their leaf characteristics (shape, veins, and keypoints. Shape and veins of leaves are recognized by Invariant Moment Method as the feature extraction. City Block Distance used to calculate the distance between the features. Whereas for detection and keypoints extraction using Oriented FAST and Rotated BRIEF on OpenCV library. This keypoints distance calculation using Brute-Force Hamming. Matching is done by calculating the shortest distance between test image and reference image. If the result is less than or equal to threshold then image is match. Experiment result show this application can achieve 79% of success rate by using keypoints. This result is influenced by glossy leaf surface, so there is many reflected light that become noise.

    Full Text Available This paper aims in classifying and identifying the diseases of mango leaves for Indian agriculture. K-means algorithm is chosen for the disease segmentation, and the disease classification and identification is carried out using the SVM classifier. Disease identification based on analysis of patches or discoloring of leaf will hold good for some of the plant diseases, but some other diseases which will deform the leaf shape cannot be identified based on the same method. In this case leaf shape based disease identification has to be performed. Based on this analysis two topics are addressed in this research paper.

    Three new metal complexes derived from Pd(II), Ru(III) and Zr(IV) with (E)-2-amino-N-(1-(2-aminophenyl)ethylidene)benzohydrazide (2-AAB) have been synthesized. The isolated complexes were characterized by elemental analyses, FT-IR, UV-Vis, ES-MS, (1)H NMR, XRD, thermal analyses (TGA and DTA) and conductance. The morphology and the particle size were determined by transmittance electron microscope (TEM). The results showed that, the ligand coordinates to Pd(II) in the enol form, while it coordinates to Ru(III) and Zr(IV) in the keto form. A square planar geometry is suggested for Pd(II) complex and octahedral geometries are suggested for Ru(III) and Zr(IV) complexes. The optical band gaps of the isolated complexes were measured and indicated the semi-conductivity nature of the complexes. The anti-inflammatory and analgesic activities of the ligand and its complexes showed that, Ru(III) complex has higher effect than the well known drug "meloxicam".

    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'.

    Full Text Available A protocol for the in vitro culture of Cucurbita pepo cv. Caserta was studied, using a cotyledon segment with an attached hypocotyl fragment as an explant. First, to determine the optimal seedling age, explants were collected from 4 to 6-day-old in vitro germinated seedlings and cultured in MS basal medium supplemented with benzylaminopurine (BAP, 4.5 µM, under a 16-h photoperiod at 27ºC. Based on the results obtained, the explants collected from the 4-day-old seedlings were then cultured in MS basal medium supplemented with different concentrations of BAP (0, 1.1, 2.2, 3.3, 4.5, or 5.5 µM and incubated under a 16-h photoperiod at 27ºC. In vitro organogenesis was most efficient with explants collected from 4-day-old seedlings cultured in medium supplemented with 4.5 µM of BAP. After 4 weeks of incubation the development of adventitious buds at the cotyledon/hypocotyl junction could be observed. These buds were transferred to elongation and rooting medium and the developed plants were acclimatized to greenhouse conditions. The morphogenic process was characterized using light and scanning electron microscopy analyses to confirm the organogenesis. The results showed that this alternate explant is efficient for in vitro culture of zucchini squash cv. Caserta. The protocol will be further examined for future use in genetic transformation experiments in this species.O objetivo do trabalho foi estudar um protocolo para o cultivo in vitro de Cucurbita pepo cv.

    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

    SiGe alloys are currently used for HBT and MOS as epitaxial layers for base or strained channel, respectively. In the poly phase, SiGe has been studied as a replacement for poly-Si in MOS gates due to its lower thermal budget and gate depletion and also due to the Workfunction Engineering for V {sub t} adjustments. However, for application to CMOS technology as poly-SiGe gates, others constrains emerge such as quality of the oxide interface and etch chemistry. For both applications, the Ge fraction normally lies between 20% and 40%. In this study, authors use a low Ge contents (1%) poly-SiGe thin films aiming for MOS gate electrode. The Ge fraction was determined by RBS analysis. 230 nm thick samples were deposited onto 10 nm thermally oxidized <1 0 0>, p-type Si substrates using silane and germane. Films were deposited in the temperature of 500 deg. C and total pressure of 667 Pa (5 Torr) by vertical LPCVD. The samples were doped using {sup 31}P{sup +} ion implantation from 5 x 10{sup 14} cm{sup -2} up to 2 x 10{sup 16} cm{sup -2} and annealed by RTP (40 s) from 500 deg. C up to 900 deg. C. R {sub s} values were obtained by 4-point probe technique and CV curves were extracted from nMOS capacitors with 200 {mu}m diameter. The same processing steps were used to fabricate similar poly-Si samples and capacitors for comparison. The poly-SiGe samples presented R {sub s} values one order of magnitude lower than poly-Si and CV analysis of nMOS capacitors showed very good characteristics. The 1% Ge in the alloy ensures a low thermal budget for the overall process. Although a relatively high annealing temperature (800 deg. C) must be used to reduce oxide charge and interface traps, the temperature is well below the necessary for poly-Si processing and can allow formation of the shallow junctions needed for next technological nodes.

    The safety and nutritional properties of CV127 soybeans were evaluated in rat and broiler feeding studies. Some episodic differences were observed between rats fed CV127, Conquista, and the standard diet for the endpoints examined. None of these differences were considered treatment related, adverse, or biologically meaningful. In general, birds fed diets containing CV127, Conquista, or Monsoy 8001 showed no significant differences in growth and performance response variables. Chickens fed diets containing Coodetec 217 had lower body weight and weight gain for all developmental periods compared to CV127, but no significant differences were found in feed conversion for the two diets during any development period. The results of both feeding studies demonstrate that CV127 soybeans are as safe, wholesome, and nutritionally valuable as the other soybean meals tested, including those varieties for which histories of safe use have been established and well documented.

    The cultivar Loureiro of Vitis vinifera is one of the most economically important, recommended in almost the totality of the Região Demarcada dos Vinhos Verdes. In vineyards, the grape productivity of this cultivar is normal while in others it is extremely low. The aim of this work was to study the morphology and germination of Vitis vinifera cv. Loureiro pollen with high and low productivity. The pollen grain was examined under light, transmission and scanning electron microscopy. Typically V. vinifera pollen present three furrows but in the cultivar Loureiro we found tricolporated and acolporated (without furrows or pores) pollen grains. Both pollen types present generative and vegetative cells with the usual aspect and a dense cytoplasm rich in organelles. In the acolporated pollen a continuous exine layer and an irregular intine layer were observed. Differences were found in the starch accumulation, since only in tricolporated pollen abundant plastids filled with numerous starch granules were observed. To determine the causes of the low productivity of this cultivar we tested pollen viability by the fluorochromatic reaction and pollen germinability by in vitro assays. We observed that the acolporated pollen grain is viable, but no germination was recorded.

    A 5.4-kDa antifungal peptide,with an N-terminal sequence highly homologous to defensins and inhibitory activity against Mycosphaerella arachidicola (IC5o=3 μM),Setospaeria turcica and Bipolaris maydis,was isolated from the seeds of Phaseolus vulgaris cv.brown kidney bean.The peptide was purified by employing a protocol that entailed adsorption on Affi-gel blue gel and Mono S and finally gel filtration on Superdex 75.The antifungal activity of the peptide against M.arachidicola was stable in the pH range 3-12 and in the temperature range 0℃ to 80℃.There was a slight reduction of the antifungal activity at pH 2 and 13,and the activity was indiscernible at pH 0,1,and 14.The activity at 90℃ and 100℃ was slightly diminished.Deposition of Congo red at the hyphal tips of M.arachidicola was induced by the peptide indicating inhibition of hyphal growth.The lack of antiproliferative activity of brown kidney bean antifungal peptide toward tumor cells,in contrast to the presence of such activity of other antifungal peptides,indicates that different domains are responsible for the antifungal and antiproliferative activities.

    A 5.4-kDa antifungal peptide, with an N-terminal sequence highly homologous to defensins and inhibitory activity against Mycosphaerella arachidicola (IC(50)= 3 μM), Setospaeria turcica and Bipolaris maydis, was isolated from the seeds of Phaseolus vulgaris cv. brown kidney bean. The peptide was purified by employing a protocol that entailed adsorption on Affi-gel blue gel and Mono S and finally gel filtration on Superdex 75. The antifungal activity of the peptide against M. arachidicola was stable in the pH range 3-12 and in the temperature range 0°C to 80°C. There was a slight reduction of the antifungal activity at pH 2 and 13, and the activity was indiscernible at pH 0, 1, and 14. The activity at 90°C and 100°C was slightly diminished. Deposition of Congo red at the hyphal tips of M. arachidicola was induced by the peptide indicating inhibition of hyphal growth. The lack of antiproliferative activity of brown kidney bean antifungal peptide toward tumor cells, in contrast to the presence of such activity of other antifungal peptides, indicates that different domains are responsible for the antifungal and antiproliferative activities.

    2008-01-01

    We present new V-band differential brightness measurements as well as new radial-velocity measurements of the detached, circular, 0.84-day period, double-lined eclipsing binary system CV Boo. These data along with other observations from the literature are combined to derive improved absolute dimensions of the stars for the purpose of testing various aspects of theoretical modeling. Despite complications from intrinsic variability we detect in the system, and despite the rapid rotation of the components, we are able to determine the absolute masses and radii to better than 1.3% and 2%, respectively. We obtain M(A) = 1.032 +/- 0.013 M(Sun) and R(B) = 1.262 +/- 0.023 R(Sun) for the hotter, larger, and more massive primary (star A), and M(B) = 0.968 +/- 0.012 M(Sun) and R(B) = 1.173 +/- 0.023 R(Sun) for the secondary. The estimated effective temperatures are 5760 +/- 150 K and 5670 +/- 150 K. The intrinsic variability with a period about 1% shorter than the orbital period is interpreted as being due to modulatio...

  18. Future Objectives of Maintenance Management in the CV Group

    Annila, L

    1999-01-01

    The ST/CV group has an extensive maintenance contract with a multinational consortium (Gematec-F/I/DE). Annually, the contract costs the group about 6 MCHF. Today the technical monitoring of the performance within the contract has become too irregular and different people's roles have not been sufficiently well defined. It has therefore been decided that all the technical, financial and performance-indicating data should be centrally co-ordinated within the group. The objective is to enable an efficient follow-up of the contract with a view to optimization. Another objective is to migrate to the new, more proficient version of the Computer Aided Maintenance Management (CAMM) software and learn to use it to its full potential. This means using its statistics and analysis features in addition to controlling the maintenance activities, spare-parts store, costs, etc. A further aim is to develop standards for the maintenance and the CAMM. This paper will discuss these objectives and the schedule for their implemen...

  19. Seven health physics calculator programs for the HP-41CV

    Energy Technology Data Exchange (ETDEWEB)

    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.

    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.

  1. 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

    2007-01-01

    Our goal was to improve the fundamental parameters of the massive close double-lined eclipsing B2.5V+B2.5V binary CV Velorum.We gathered new high-resolution echelle spectroscopy on 13 almost consecutive nights covering essentially two orbits. We computed a simultaneous solution to all the available high-quality radial-velocity and light data with the latest version of the Wilson-Deviney code. We obtained the following values for the physical parameters: $M_1 = 6.066(74) M_\\odot$, $M_2 = 5.972(70) M_\\odot$, $R_1 = 4.126(24) R_\\odot$, $R_2 = 3.908(27) R_\\odot$, $\\log L_1 = 3.20(5) L_\\odot$, and $\\log L_2 = 3.14(5) L_\\odot$. The quoted errors contain a realistic estimate of systematic uncertainties mainly stemming from the effective temperature estimation. We derived abundances for both components and found them to be compatible with those of B stars in the solar neighbourhood. We discovered low-amplitude periodic line-profile variations with the orbital frequency for both components. Their interpretation requir...

    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.

    Rogel, A B; Lugger, P M

    2007-01-01

    For purposes of designing targeted cataclysmic variable (CV) detection surveys and interpreting results of other projects with many CV detections such as the ChaMPlane Survey, we have created a model of the CV distribution in the Galaxy. It is modeled as a warped, flared exponential disk with a gaussian vertical distribution. Extinction is based on a detailed Galactic dust and gas model. A luminosity function for CVs is also incorporated, based on a smoothed version of published data. We calculate predicted field detection rates as a function of the limiting magnitude expected for the detecting system (i.e. WIYN/Hydra or NOAO 4m/Mosaic). Monte-Carlo techniques are used to assess statistical fluctuations in these rates. We have created maps of the expected CV distribution for the full non-bulge Galactic plane (20CV surveys. Assuming a CV distribution with a scale height of 160 pc, the ChaMPlane observational result of 5 CVs in 13 northern...

La presente contribución da a conocer los resultados del análisis sedimentológico y paleoambiental de las Formaciones Bajo de la Carpa (Santoniano y Anacleto (Campaniano inferior. Los estudios llevados a cabo permitieron definir cuatro litofacies conglomerádicas, nueve de areniscas y dos pelíticas, que fueron agrupadas en nueve asociaciones de litofacies, dos de ellas de origen eólico y siete fluviales. La Formación Bajo de la Carpa está representada en la base por un sistema fluvial efímero, y en el techo por depósitos de interacción fluvio- eólica. Los depósitos fluviales corresponden a flujos canalizados durante episodios de máxima descarga. Luego se identifica un campo de dunas transversales, afectado en el subambiente de interduna por corrientes fluviales efímeras, y dunas parabólicas producto de la removilización del sistema eólico infrayacente, asociadas con depósitos de flujos efímeros en manto. La extensión y geometría de los campos de dunas respondieron a variaciones climáticas de corto término, interferencia del sistema fluvial, oscilaciones del nivel freático, bajo suministro y/o disponibilidad de sedimentos y factores tectónicos. La Formación Anacleto presenta en su base sistemas fluviales de baja sinuosidad, alta energía y rápida agradación, controlados por un bajo espacio de acomodación y condiciones climáticas con marcada estacionalidad. Hacia el tope se identifica un sistema fluvial anastomosado que refleja variaciones climáticas y aumento de la tasa de subsidencia acompañada de un lento ascenso del nivel de base relacionado con la ingresión atlántica maastrichtiana.Upper Cretaceous deposits included in Río Colorado Subgroup crop out in Neuquén city and surrounding areas.

    High precision secondary ion mass-spectrometry (SIMS) analyses of kirschsteinite (CaFeSiO4) in the reduced CV3 chondrites Vigarano and Efremovka yield well resolved 53Cr excesses that correlate with 55Mn/52Cr, demonstrating in situ decay of the extinct short-lived radionuclide 53Mn. To ensure proper correction for relative sensitivities between 55Mn+ and 52Cr+ ions, we synthesized kirschsteinite doped with Mn and Cr to measure the relative sensitivity factor. The inferred initial ratio (53Mn/55Mn)0 in chondritic kirschsteinite is (3.71 ± 0.50) × 10-6. When anchored to 53Mn-53Cr relative and U-corrected 207Pb-206Pb absolute ages of the D'Orbigny angrite, this ratio corresponds to kirschsteinite formation 3.2-0.7+08 Ma after CV Ca-, Al-rich inclusions. The kirschsteinite data are consistent within error with the data for aqueously-formed fayalite from the Asuka 881317 CV3 chondrite as reported by Doyle et al. (2015), supporting the idea that Ca-Fe silicates in CV3 chondrites are cogenetic with fayalite (and magnetite) and formed during metasomatic alteration on the CV3 parent body. Concentrically-zoned crystals of kirschsteinite and hedenbergite indicate that they initially formed as near end-member compositions that became more Mg-rich with time, possibly as a result of an increase in temperature.

    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 $\\approx 75$ d. This variation can be explained by the influence of a third star with a mass of $\\approx 0.4M_{\\odot}$ in an eccentric orbit with $e\\approx 0.9$. 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.

    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.

En esta área se llevaron a cabo estudios sedimentológicos con el objeto de determinar los paleoambientes de sedimentación y su evolución, como así también establecer los controles auto y alocíclicos más relevantes. Se definieron doce facies que fueron incluidas en seis asociaciones de facies. La naturaleza y la geometría de las asociaciones de facies sugieren el desarrollo de sistemas fluviales de baja sinuosidad, entrelazados y anastomosados, como así también dunas y mantos de arena eólicos. Los sistemas fluviales estuvieron sujetos a cambios en el régimen de descarga que se interpretan relacionados a variaciones climáticas de corto término. Las variaciones en el tamaño de grano dominante de la carga de lecho, el espesor de los cuerpos de canal y las variaciones relativas de la relación canales/planicie de inundación, responden a fluctuaciones en la descarga de más largo término. Las modificaciones en la arquitectura a gran escala también se interpretan relacionados a cambios en el nivel de base estratigráfico. En la base de la Formación Portezuelo los canales son espesos, muestran diseño entrelazado, albardones, depósitos de desborde y desarrollan una fuerte relación multilateral. Esta relación de las unidades de canal está relacionada con una tasa de suministro que, en general, es compensada por la tasa subsidencia. En los sectores distales de la planicie de inundación se desarrollan dunas y mantos eólicos. Gradualmente se registra una disminución en la relación canales/planicie de inundación.

    A method combining cyclic voltammetry (CV) with x-ray absorption fine structure (XAFS) spectroscopy, viz. CV-XAFS, has been developed to enable in situ real-time investigation of atomic and electronic structures related to electrochemical reactions. We use this method to study the reaction of a Pt/C cathode catalyst in the oxygen reduction reaction (ORR) in an alkaline electrolyte, using x-ray energies near the Pt LIII edge for XAFS measurements. It was found that the current induced by the ORR was first observed at approximately 0.08 V versus Hg/HgO, although the Pt valence, which is reflected in the oxidation states, remained almost unchanged. The electronic structure of the catalytic surface in the ORR was observed to be different in the negative and positive scan directions of CV measurements. Hydrogen adsorption is also discussed on the basis of the observation of this spectral change. We have demonstrated that CV-XAFS provides dynamical structural and electronic information related to electrochemical reactions and can be used for in situ real-time measurements of a catalyst.

    Using the complete GAMA-I survey covering ~142 sq. deg. to r=19.4, of which ~47 sq. deg. is to r=19.8, we create the GAMA-I galaxy group catalogue (G3Cv1), generated using a friends-of-friends (FoF) based grouping algorithm. Our algorithm has been tested extensively on one family of mock GAMA lightcones, constructed from Lambda-CDM N-body simulations populated with semi-analytic galaxies. Recovered group properties are robust to the effects of interlopers and are median unbiased in the most important respects. G3Cv1 contains 14,388 galaxy groups (with multiplicity >= 2$), including 44,186 galaxies out of a possible 110,192 galaxies, implying ~40% of all galaxies are assigned to a group. The similarities of the mock group catalogues and G3Cv1 are multiple: global characteristics are in general well recovered. However, we do find a noticeable deficit in the number of high multiplicity groups in GAMA compared to the mocks. Additionally, despite exceptionally good local spatial completeness, G3Cv1 contains signif...

    This study develops a procedure that is related to Generalized Likelihood Uncertainty Estimation (GLUE), called the CV-GLUE procedure, for assessing the predictive uncertainty that is associated with different model structures with varying degrees of complexity. The proposed procedure comprises model calibration, validation, and predictive uncertainty estimation in terms of a characteristic coefficient of variation (characteristic CV). The procedure first performed two-stage Monte-Carlo simulations to ensure predictive accuracy by obtaining behavior parameter sets, and then the estimation of CV-values of the model outcomes, which represent the predictive uncertainties for a model structure of interest with its associated behavior parameter sets. Three commonly used wetland models (the first-order K-C model, the plug flow with dispersion model, and the Wetland Water Quality Model; WWQM) were compared based on data that were collected from a free water surface constructed wetland with paddy cultivation in Taipei, Taiwan. The results show that the first-order K-C model, which is simpler than the other two models, has greater predictive uncertainty. This finding shows that predictive uncertainty does not necessarily increase with the complexity of the model structure because in this case, the more simplistic representation (first-order K-C model) of reality results in a higher uncertainty in the prediction made by the model. The CV-GLUE procedure is suggested to be a useful tool not only for designing constructed wetlands but also for other aspects of environmental management.

    Full Text Available BACKGROUND: Among scorpion species, the Buthidae produce the most deadly and painful venoms. However, little is known regarding the venom components that cause pain and their mechanism of action. Using a paw-licking assay (Mus musculus, this study compared the pain-inducing capabilities of venoms from two species of New World scorpion (Centruroides vittatus, C. exilicauda belonging to the neurotoxin-producing family Buthidae with one species of non-neurotoxin producing scorpion (Vaejovis spinigerus in the family Vaejovidae. A pain-inducing α-toxin (CvIV4 was isolated from the venom of C. vittatus and tested on five Na(+ channel isoforms. PRINCIPAL FINDINGS: C. vittatus and C. exilicauda venoms produced significantly more paw licking in Mus than V. spinigerus venom. CvIV4 produced paw licking in Mus equivalent to the effects of whole venom. CvIV4 slowed the fast inactivation of Na(v1.7, a Na(+ channel expressed in peripheral pain-pathway neurons (nociceptors, but did not affect the Na(v1.8-based sodium currents of these neurons. CvIV4 also slowed the fast inactivation of Na(v1.2, Na(v1.3 and Na(v1.4. The effects of CvIV4 are similar to Old World α-toxins that target Na(v1.7 (AahII, BmK MI, LqhIII, OD1, however the primary structure of CvIV4 is not similar to these toxins. Mutant Na(v1.7 channels (D1586A and E1589Q, DIV S3-S4 linker reduced but did not abolish the effects of CvIV4. CONCLUSIONS: This study: 1 agrees with anecdotal evidence suggesting that buthid venom is significantly more painful than non-neurotoxic venom; 2 demonstrates that New World buthids inflict painful stings via toxins that modulate Na(+ channels expressed in nociceptors; 3 reveals that Old and New World buthids employ similar mechanisms to produce pain. Old and New World α-toxins that target Na(v1.7 have diverged in sequence, but the activity of these toxins is similar. Pain-inducing toxins may have evolved in a common ancestor. Alternatively, these toxins may be the

    The daily level of physical activity was estimated using the heart rate monitor, PE3000 (Polar Electro, Finland). The level was expressed with the coefficient of variation (CV) of heart rates recorded from waking time to dinner time. In the course of a day of intense physical activity, CV was confirmed to rise significantly. Then the CV was estimated and compared among 3 age classes, young (10-18 years), middle-aged (30-47 years), and elderly (62-76 years). The CVs of young people were significantly higher than those of middle-aged (P < 0.001) and elderly (P < 0.01), regardless of sex. However there was no significant sex difference in all age classes. These results suggest that the CV is an accurate index of daily physical activity. Thus clinicians can use the CV of heart rates to estimate the level of physical activity of individuals which closely relates to QOL.

    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.

    In the rosaceous subtribe Pyrinae (formerly subfamily Maloideae), pathogen attack leads to formation of biphenyls and dibenzofurans. Accumulation of these phytoalexins was studied in greenhouse-grown grafted shoots of Malus domestica cv. 'Holsteiner Cox' and Pyrus communis cv. 'Conference' after inoculation with the fire blight bacterium, Erwinia amylovora. No phytoalexins were found in leaves. However, both classes of defence compounds were detected in the transition zone of stems. The flanking stem segments above and below this zone, which were necrotic and healthy, respectively, were devoid of detectable phytoalexins. The transition zone of apple stems contained the biphenyls 3-hydroxy-5-methoxyaucuparin, aucuparin, noraucuparin and 2'-hydroxyaucuparin and the dibenzofurans eriobofuran and noreriobofuran. In pear, aucuparin, 2'-hydroxyaucuparin, noreriobofuran and in addition 3,4,5-trimethoxybiphenyl were detected. The total phytoalexin content in the transition zone of pear was 25 times lower than that in apple. Leaves and stems of mock-inoculated apple and pear shoots lacked phytoalexins. A number of biphenyls and dibenzofurans were tested for their in vitro antibacterial activity against some Erwinia amylovora strains. The most efficient compound was 3,5-dihydroxybiphenyl (MIC=115 μg/ml), the immediate product of biphenyl synthase which initiates phytoalexin biosynthesis.

    The peels of Citrus aurantium L. and Citrus sinensis Osbeck cultivars from the Dubrovnik region (south Croatia) were extracted by supercritical CO2 at 40 degrees C and 10 MPa at 1.76 kg/h to obtain enriched extracts in comparison with simple pressing of the peels. The extracts were analyzed in detail by gas chromatography and mass spectrometry (GC-FID/MS). Relevant similarities among the peel oil compositions of C. aurantium and C. sinensis cultivars were found with limonene predominance (up to 54.3%). The principal oxygenated monoterpenes were linalool (3.0%-5.9%), α-terpineol (0.7%-2.4%), linalyl acetate (0.0%-5.0%), geranyl acetate (0.0%-0.4%), (Z)-citral (0.0%-1.8%) and (E)-citral (0.0%-1.9%). Several sesquiterpenes were found with minor percentages. Coumarin derivatives were identified in all the samples among the relevant compounds. Isogeijerin dominated in the peels of C. sinensis cv. Tarocco (15.3%) and C. aurantium (11.2%). Scoparone ranged from 0.1% to 0.5% in all the samples. Bergapten (up to 1.4%), osthole (up to 1.1%) and 7-methoxy-8-(2-formylpropyl)coumarin (up to 1.1%) were found mostly in C. sinensis cv. Doppio Sanguigno. It was possible to indicate a few other differences among the extracts such as higher percentage of linalool, linalyl and geranyl acetates, as well as the abundance of sabinene and isogeijerin in C. aurantium or the occurrence of β-sinensal in C. sinensis cultivars.

    Full Text Available Primary and secondary infections with PVYNTN were investigated on forty plants of the potato cv. Romano inoculated in a greenhouse in Serbia in 2012 and 2013. PVY isolates were collected from the potato growing region of Čačak and identified by ELISA and RT-PCR methods. The sequence of the Serbian isolate 3D (Acc. No. KJ946936 showed 100% match with seven PVY isolates deposited in GenBank and described as NTN. A significant difference was detected between PVYNTN symptoms exibited on leaves of the cv. Romano under primary and secondary infections. The findings are significant because they are based on symptoms observed, so that it is clear that there are two distinct types of infection: primary and secondary. Symptoms of primary and secondary infection were the same on potato tubers and had the form of necrotic rings.

    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.

    Full Text Available Sour cherry cv. Marasca is Dalmatian cultivar from XVI century. Cultivation is limited on the north and central part of Dalmatia and on the part of the islands, where it achieves the best quality of fruit, high content of dry matter and sugar respectively, agreeable aroma and intense color. Sour cherry cv. Marasca is source of biologically active ingredients, organic and inorganic compounds, dietary fibers, aromatic compounds and high content of phenolic compounds, particularly anthocyanins and hormone melatonin. Many epidemiological studies showed that phenolic compounds have antioxidant and anti-inflammatory properties, and they have beneficial effect on human health. Marasca is rich with mentioned compounds. Physicochemical composition (total and soluble dry matter, pH value, total acidity during ripening of cv. Marasca ecotype Recta (Cerasus marasca recta grown in Zadar and Split area were determined. Total and soluble dry matter increased and pH value and total acidity showed little change during ripening. The content of phenolic compounds increased during ripening as well as content of anthocyanins, while antioxidant activity decreased with ripening. That indicates there was no correlation between antioxidant activity and content of total phenolic compounds.

    Platelet adhesion is a critical step due to its hemostatic role in stopping bleeding after vascular damage. Short dystrophins are the most abundant dmd gene products in nonmuscle tissues, and in association with cytoskeleton proteins contribute to their intrinsic function; while utrophins are dystrophin-homologous related family proteins with structural and functional similarities. We previously demonstrated the presence of Dp71 isoforms, utrophins, and various dystrophin-associated proteins and their participation in cytoskeleton re-organization, filopodia and lamellipodia extension, and in centralizing cytoplasmic granules during the adhesion process of human platelets. To evaluate the morphologic changes and actin-based structures of mdx(3cv) platelets during the adhesion process, we compared the topographic distribution of Dp71d/Dp71Delta110(m) and dystrophin-associated protein in adhered platelets from dystrophic mdx(3cv) mouse. By confocal microscopy, we showed that absence of Dp71 isoforms in platelets from this animal model disrupted dystrophin-associated protein expression and distribution without modifying the platelet morphology displayed during the glass-adhesion process. By immunoprecipitation assays, we proved that up-regulated utrophins were associated with dystrophin-associated proteins to conform the dystrophin-associated protein complex corresponding to utrophins, which might compensate for Dp71 absence in mdx(3cv) platelets.

    The aim of this research is to investigate the heat transfer characteristics of a top heat mode closed-looped oscillating heat pipe with check valves (THMCLOHP/CV). Ethanol is used as a working fluid with filling ratios of 30, 50, and 80% of the total volume of the tube. The THMCLOHP/CV is made of a copper tube with an inside diameter of 2.03 mm. The angle of inclination is 90° from the horizontal axis with 40 turns, two check valves, and an evaporator length of 50, 100, and 150 mm. The operating temperatures are 44 and 55°C. It is found that the thermal resistance decreases significantly as the working temperature is increased. Thus, the evaporator length affects the thermal resistance of the THMCLOHP/CV. The presence of the THMCLOHP/CV is clearly demonstrated to contribute to thermal performance improvement.

    The Geriatric Anxiety Inventory (GAI) was developed to assess anxiety in older adults. The objectives of this work were as follows: (a) to analyze the psychometric properties of the Chinese version of the GAI (GAI-CV), and (b) to explore the extent of anxiety and related factors in the elderly Chinese residents of Beijing. Participants in this study included 1,047 people (59.4% female) more than 60 years old who were living in the community. They were randomly selected from 15 communities in Beijing. Basic information was collected. Anxiety was measured using the GAI-CV, the Self-Rating Anxiety Scale (SAS), and the Beck Anxiety Inventory (BAI). The GAI-CV exhibited good internal consistency (Cronbach's α = 0.94) and demonstrated good concurrent validity against the SAS (r = 0.52, p = 0.018) and the BAI (r = 0.560, p = 0.000). Item response theory (IRT) analyses showed that the items of the GAI-CV exhibited high difficulty (0.97-2) and discrimination parameters (1.91-5.33). The items exhibited information parameters greater than 1.25 with the exceptions of items 2, 12, and 18. The GAI-CV scores were significantly associated with gender, age, and chronic disease. However, no significant differences due to marriage or education were found. The GAI is a new scale that was specifically designed to measure anxiety in older people. The results of this study suggest that the GAI-CV had good psychometric properties, but some items need to be modified. IRT analyses indicated that the GAI-CV provided good measures of anxiety across the moderately high to very high levels. The GAI-CV may be a useful instrument for further research studies aimed at analyzing high-level anxiety among older adults in China.

  1. Defective secretion of mucilage is the cellular basis for agravitropism in primary roots of Zea mays cv. Ageotropic

    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.

    Full Text Available The purpose of this work was to evaluate the effect of wilting and biological additive amendment on chemical composition, fermentation and ruminal degradability of Arachis pintoi cv Belmonte silage. The following treatments were analysed: T1- Arachis pintoi cv Belmonte fresh forage; T2 - Arachis pintoi cv Belmonte fresh forage plus bacterial additive added to the forage prior to the ensilage; T3- Arachis pintoi cv Belmonte wilted by the sun for 4 hours; T4- Arachis pintoi cv Belmonte wilted by the sun plus bacterial additive. The degradability assay was carried out using three rumen-fistuled steers. The biological additive did not affect the chemical composition of silages, in situ degradability of nutrients DM, NDF and CP and of silage fermentation. However, the wilting treatments of the silages increased DM, CP, hemicelulose and decreased N-NH3 concentration, pH value, degradability of soluble fraction “a” from DM NDF and CP. The analysed characteristics suggest that Arachis pintoi cv Belmonte could satisfactorily preserve the forage quality if wilted by the sun during 4 hours, after harvested.

    Describing assay error as percent coefficient of variation (CV%) fails as measurements approach zero. Results are censored if below some arbitrarily chosen lower limit of quantification (LLOQ). CV% gives incorrect weighting to data obtained by therapeutic drug monitoring, with incorrect parameter values in the resulting pharmacokinetic models, and incorrect dosage regimens for patient care. CV% was compared with the reciprocal of the variance (1/var) of each assay measurement. This method has not been considered by the laboratory community. A simple description of assay standard deviation (SD) as a polynomial function of the assay measurement over its working range was developed, the reciprocal of the assay variance determined, and its results compared with CV%. CV% does not provide correct weighting of measured serum concentrations as required for optimal therapeutic drug monitoring. It does not permit optimally individualized models of the behavior of a drug in a patient, resulting in incorrect dosage regimens. The assay error polynomial described here, using 1/var, provides correct weighting of such data, all the way down to and including zero. There is no need to censor low results, and no need to set any arbitrary LLOQ. Reciprocal of variance is the correct measure of assay precision and should replace CV%. The information is easily stored as an assay error polynomial. The laboratory can serve the medical community better. There is no longer any need for LLOQ, a significant improvement. Regulatory agencies should implement this more informed policy.

    Purpose: Accurate detection of pulmonary nodules remains a technical challenge in computer-aided diagnosis systems because some nodules may adhere to the blood vessels or the lung wall, which have low contrast compared to the surrounding tissues. In this paper, the analysis of typical shape features of candidate nodules based on a shape constraint Chan–Vese (CV) model combined with calculation of the number of blood branches adhered to nodule candidates is proposed to reduce false positive (FP) nodules from candidate nodules. Methods: The proposed scheme consists of three major stages: (1) Segmentation of lung parenchyma from computed tomography images. (2) Extraction of candidate nodules. (3) Reduction of FP nodules. A gray level enhancement combined with a spherical shape enhancement filter is introduced to extract the candidate nodules and their sphere-like contour regions. FPs are removed by analysis of the typical shape features of nodule candidates based on the CV model using spherical constraint and by investigating the number of blood branches adhered to the candidate nodules. The constrained shapes of CV model are automatically achieved from the extracted candidate nodules. Results: The detection performance was evaluated on 127 nodules of 103 cases including three types of challenging nodules, which are juxta-pleural nodules, juxta-vascular nodules, and ground glass opacity nodules. The free-receiver operating characteristic (FROC) curve shows that the proposed method is able to detect 88% of all the nodules in the data set with 4 FPs per case. Conclusions: Evaluation shows that the authors’ method is feasible and effective for detection of three types of nodules in this study.

    Full Text Available High percentage of callus induction at 97% was obtained when seeds of rice (Oryza sativa L. cv. RD6 were cultured on modified N6 medium supplemented with 3% (w/v sucrose, 22.5 μM 2,4-D and 0.8% agar under light condition. The suitable regeneration medium was N6 medium supplemented with 3% (w/v sucrose, 2.5 μM IAA, 18 μM BA and 0.8% agar. A test had been performed to determine the effect of antibiotics on the regeneration of rice cv. RD6. It was found that kanamycin concentration up to 150 mg l-1 and hygromycin concentration at 10 mg l-1 were effective for selection of transformants. Cefotaxime and carbenicillin concentration up to 250 mg l-1 had the highest phytotoxicity to plant regeneration. Agrobacterium-mediated gene transfer protocols for rice cv. RD6 were performed using A. tumefaciens strain LBA4404, which harbored the plasmid pBI121 containing genes for β- glucuronidase (GUS and kanamycin resistance (nptII, and strain EHA105, which harbored plasmid pCAMBIA1301 containing genes for β-glucuronidase (GUS and hygromycin resistance (hptII. GUS activities were found in rice calli after co-cultivation. A number of morphologically normal fertile transgenic rice plants were obtained. Stable integration, expression and inheritance of transgenes were demonstrated by molecular and genetic analysis of transgenic plants in T0 and T1 generation. Mendelian segregation was observed in T1 progeny.

    Full Text Available Citrus medica cv. ‘liscia’ and C. medica cv. ‘rugosa’ are two taxa of citron, belonging to the biodiversity of South Italy, in particular of Amalfi Coast, in the Campania region. The chemical composition of the essential oils (EOs from fruit peels of both C. medica cultivars was studied by gas chromatography (GC and gas chromatography-mass spectrometry (GC-MS analyses. In all, 100 compounds were identified, 82 for C. medica cv. ‘liscia’, accounting for 91.4% of the total oil, and 88 for C. medica cv. ‘rugosa’, accounting for 92.0% of the total oil. Monoterpene hydrocarbons are the main constituents in both oils of C. medica cv. ‘liscia’ (79.1% and C. medica cv. ‘rugosa’ (80.2%. In both oils, limonene (67.2%–62.8% and camphene (8.5%–10.9% are the main constituents. The antimicrobial activity of the EOs was assayed against some bacterial strains: Bacillus cereus (DSM 4313, Bacillus cereus (DSM 4384, Staphylococcus aureus (DSM 25693, Pseudomonas aeruginosa (ATCC 50071, and Escherichia coli (DSM 8579. Low concentrations of C. medica cv. ‘rugosa’ EO showed an inhibitory effect on P. aeruginosa and higher concentrations inhibited more B. cereus (4384 and E. coli than S. aureus. The cytotoxicity of the EO was evaluated against SH-SY5Y cell line. The influence of the EO on the expression of adenylate cyclase 1 (ADCY1 was also studied. The antimicrobial activity registered confirm their traditional uses as food preserving agents and led us to hypothesize the possible use of these oils as antimicrobials. The alterations in ADCY1 expression suggested a role for limonene in effects on the central nervous system.

In the final stage it was tested the influence of sucrose of the in vitro rooting media on the acclimatization. All the treatments showed 100% of survival. It can be concluded that an efficient in vitro rooting can be realized without both IBA and sucrose in the culture media with acclimatization under plastic tunnel or ex vitro rooting and acclimatization

    Phosphorus is considered an essential element for plants, but it is found in low amounts in Brazilian soils, mainly in areas destined to pastures, and the application of organic matter contributes to the improvement of physical, chemical and biological soil attributes. The research had the objective of evaluating the application effects of the Bokashi organic compound on soil macro and micronutrients contents and leaves, as well as on Brachiaria brizantha cv. Marandú dry mass yield, evaluating the potential of the organic fertilizer as phosphorus source, in comparison with conventional chemical fertilizers. Different organic compound doses supplied the soil with 17 kg P2O5 ha-1, 34 kg P2O5 ha-1, 68 kg P2O5 ha-1, 136 kg P2O5 ha-1, and 204 kg P2O5 ha-1, comparing it with the conventional chemical fertilizer and the control. The results revealed that the organic fertilizer Bokashi can adequately replace the conventional chemical fertilizer of Brachiaria brizantha cv. Marandú, supplying the soil and plant with appropriate nutrients levels and maintaining the dry mass yield.

    In order to identification of the possibility of manufacturing soybean paste (doenjang) with soybean mutant lines induced from gamma-ray mutagenesis, this study was performed to investigate the quality characteristics of doenjang using two soybean mutant lines, Baekwon-1 (BW-1) and Baekwon-2 (BW-2) and their original cultivar (cv. Baekwon, BW) for 8 weeks. The BW and two mutant lines (BW-1 and BW-2) were showed higher content of amino type nitrogen than control (cv. Taegwang). The pH decreased and the titratable acidity increased all the samples during aging period. The lightness, redness and yellowness of doenjang were the lowest in BW. Total free sugar content of doenjang was the highest in control (10.43%) after 4 weeks and composed mainly fructose and glucose. The order of the free amino acid content was Glutamic acid>Leucine>Lysine>Phenylalanine>Aspartic acid in control, Glutamic acid>Leucine >Arginine>Lysine>Phenylalanine in BW, Glutamic acid>Lysine>Phenylalanine>Aspartic acid>Valine in BW-1 and Glutamic acid>Arginine>Lysine>Phenylalanine>Aspartic acid in BW-2, respectively. Our results showed that it is possible to increase the quality of doenjang using soybean mutant lines in manufacturing soybean paste.

    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.

    Plasmalemmal vesicle associated protein (Plvap/PV1) is a structural protein required for the formation of the stomatal diaphragms of caveolae. Caveolae are plasma membrane invaginations that were implicated in SV40 virus entry in primate cells. Here we show that de novo Plvap/PV1 expression in CV-1 green monkey epithelial cells significantly reduces the ability of SV40 virus to establish productive infection, when cells are incubated with low concentrations of the virus. However, in presence of high viral titers PV1 has no effect on SV40 virus infectivity. Mechanistically, PV1 expression does not reduce the cell surface expression of known SV40 receptors such as GM1 ganglioside and MHC class I proteins. Furthermore, PV1 does not reduce the binding of virus-like particles made by SV40 VP1 protein to the CV-1 cell surface and does not impact their internalization when cells are incubated with either high or low VLP concentrations. These results suggest that PV1 protein is able to block SV40 infectivity at low but not at high viral concentration either by interfering with the infective internalization pathway at the cell surface or at a post internalization step.

    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 {mu}g L{sup -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{sup -1} and the relative standard deviation was 3.9% at levels around of 0.4 {mu}g L{sup -1} Hg.

    This subchronic duration feeding study evaluated the nutritional and health status of rats fed diets containing CV127 at incorporation levels of 11% and 33%. For control comparisons, rats were also exposed to similar incorporation levels of the near isogenic conventional soybean variety (Conquista) and two other conventional soybean varieties (Monsoy, Coodetec). In spite of phenotypic differences among these four soybean varieties, there were no quantitative differences in their respective proximate and other compositional properties, including proteins, amino acids, antinutrients and nutritional cofactors. All diets were prepared by blending the respective processed soybean meal with ground Kliba maintenance meal at high (33%) and low (11%) incorporation levels, and the blended diets were fed to Wistar rats for about 91 days. Although there were some isolated parameters indicating statistically significant changes, these lacked consistency and a plausible mechanism and were thus assessed to be incidental. The totality of results demonstrate that CV127 soybeans are similar with respect to their nutritional value and systemic effects as its near isogenic conventional counterpart, as well as other conventional soybean varieties. Hence, introduction of AHAS gene into soybeans does not substantially alter its compositional properties, nor adversely affect its nutritional or safety status to mammals.

    In the present work the first results obtained with the low energy proton beam of CV-28 at IEN/CNEN and the prototype of a computerized tomography device developed in UFTPR are presented. The system installed in the scatterings chamber of the cyclotron line 3 includes the proton scatter, turntable with translation (1st generation CT scheme), the set of collimators for the secondary proton beam formation and the Si(Li) ORTEC detector. The main parameters of the tomography turntable and the collimators were chosen based on computer simulations with SRIM2006 and GEANT4. A cylindrical glass tube was used as the irradiated sample. On this stage, only the translation of the turntable perpendicular to the proton beam direction was fulfilled. The measured proton energy spectra have, in general, a predicted behavior. However, the experiment revealed some problems with the secondary proton beam formation that should be solved prior to obtain a first pCT image at CV-28. (author)

    Full Text Available ABSTRACT The purpose of this study was to evaluate the salt tolerance of mini watermelon (cv. Smile. The experiment was carried out in the greenhouse of the Department of Biosystems Engineering of ESALQ/USP. The experimental design was randomized blocks. The plants were irrigated with five levels of salinity (S1 = 1.0; S2 = 2.0; S3 = 3.0; S4 = 4.0 and S5 = 5.0 dS m-1. At 85 days after the beginning of the experiment, the plants and the physical and chemical variables of the fruit were evaluated. Salinity negatively affected the variables: length of the main stem, stem diameter, number of leaves, number of branches, leaf area, fresh and dry matter. Regarding the physical and chemical characteristics of fruits, salinity reduced the mass, diameter and the pH of the fruit, but increased its vitamin C content. In general, the results suggest that the mini watermelon (cv. Smile is moderately sensitive to salinity.

    For multi-camera calibration systems, a method based on OpenCV and multi-view registration combining calibration algorithm is proposed. First of all, using a Zhang's calibration plate (8X8 chessboard diagram) and a number of cameras (with three industrial-grade CCD) to be 9 group images shooting from different angles, using OpenCV to calibrate the parameters fast in the camera. Secondly, based on the corresponding relationship between each camera view, the computation of the rotation matrix and translation matrix is formulated as a constrained optimization problem. According to the Kuhn-Tucker theorem and the properties on the derivative of the matrix-valued function, the formulae of rotation matrix and translation matrix are deduced by using singular value decomposition algorithm. Afterwards an iterative method is utilized to get the entire coordinate transformation of pair-wise views, thus the precise multi-view registration can be conveniently achieved and then can get the relative positions in them(the camera outside the parameters).Experimental results show that the method is practical in multi-camera calibration .

    Plants in alpine habitats are exposed to many environmental stresses, in particular temperature and radiation extremes. Recent field experiments on Arnica montana L. cv. ARBO indicated pronounced altitudinal variation in plant phenolics. Ortho-diphenolics increased with altitude compared to other phenolic compounds, resulting in an increase in antioxidative capacity of the tissues involved. Factors causing these variations were investigated by climate chamber (CC) experiments focusing on temperature and ultraviolet (UV)-B radiation. Plants of A. montana L. cv. ARBO were grown in CCs under realistic climatic and radiation regimes. Key factors temperature and UV-B radiation were altered between different groups of plants. Subsequently, flowering heads were analyzed by HPLC for their contents of flavonoids and caffeic acid derivatives. Surprisingly, increased UV-B radiation did not trigger any change in phenolic metabolites in Arnica. In contrast, a pronounced increase in the ratio of B-ring ortho-diphenolic (quercetin) compared to B-ring monophenolic (kaempferol) flavonols resulted from a decrease in temperature by 5 degrees C in the applied climate regime. In conclusion, enhanced UV-B radiation is probably not the key factor triggering shifts in the phenolic composition in Arnica grown at higher altitudes but rather temperature, which decreases with altitude.

    2014-12-01

    Full Text Available A total of 51 doubled haploid (DH derivatives of the flue-cured true-breeding tobacco variety Wislica were obtained via anther culture and colchicine-induced chromosome doubling. Of that number eight DH lines showed morphological aberrations and/or reduced vigour that made them unfit to be grown in the field. The remaining 43 DH lines were grown in 2001 under regular flue-cured tobacco management and evaluated for principal growth indicators, yield, curability and gross money returns from unit area. In 2002, the evaluation was scaled down to include 13 best performing DH lines of 2001. The DH lines showed a considerable variation for basic growth parameters. Usually, the DH lines had more leaves but were shorter than the parental genotype mostly due to shorter internodes. The majority of DH lines showed delayed flowering compared to the parental cultivar. Yields of cured leaves varied extensively, some of the DH lines yielding above and some below cv. Wislica. Curability measured as percentage of light (1st to 3rd grades was generally lower in DH lines compared to that in cv. Wislica. However, because of the high leaf yield some of the DH lines were not inferior to the parental cultivar with respect to money returns from unit area.

    Grape juice and grape skin extracts are important commercial source of polyphenolic compounds which exert different functional properties such as color potential, antimicrobial, antioxidant activity, and health benefits. In this paper we describe a sensitive and specific assay for determination of bioactive polyphenolic compounds in Campbell Early (Vitis labrusca cv. baile). Five polyphenolic components were separated on an Agilent Zorbax Extend C18 Column (250 mm x 4.6 mm x 5 μm) and detected by a diode array detector. The mobile phase was composed of (a) aqueous phosphoric acid (0.2%, v/v); and (b) acetonitrile using a gradient elution. Analytes were performed at 25 degrees C with a flow rate of 0.8 ml/min and UV detection at 280, 360, and 520 nm. All calibration curves showed good linear regression (r2 ≥ 0.9999) within tested ranges. Overall intra- and inter-day variations were less than 1.90%, and the average recoveries were 95.5-105% for analytes. The antioxidant activity determined by DPPH radical assay, ranged from 86-105 for extracts, and 165-252 for studied standards (μM trolox/100 g dry wt.). The proposed method would be sensitive enough and reliable for quality control in functional food and modernization of Campbell Early (Vitis labrusca cv. baile) as potent antioxidant agents.

    Esca is a destructive disease of complex etiology affecting grapevines worldwide. A major constraint to the study and control of esca is that the disease is not diagnosed until external leaf and/or fruit symptoms are visible; however external symptoms usually appear several years after infection onset. We studied the phenolic content of V. vinifera cv. Alvarinho leaves using high performance liquid chromatography-diode array detection-mass spectrometry (HPLC-DAD-MS)/LC-MS. Leaves from affected cordons with and without visible symptoms (diseased and apparently healthy leaves, respectively) and leaves from asymptomatic cordons (healthy leaves) were analyzed. Application of principal components analysis (PCA) to HPLC data showed a clear separation between diseased, apparently healthy, and healthy leaves, with the apparently healthy leaves clustered in a medial position. Several compounds were highly correlated with diseased leaves indicating a differential phenolic production due to esca disease in V. vinifera cv. Alvarinho leaves. Total phenolic production was shown to significantly increase in diseased leaves, compared to healthy leaves, with apparently healthy leaves containing a medial amount. Trans-caffeoyltartaric acid, trans-coumaroyl-tartaric acid, quercetin-3-O-glucoside, quercetin-3-O-galactoside, kaempferol-3-glucoside and myricetin were identified among the compounds associated with disease and their content shown to change similarly to total phenolic production. This study shows that it is possible to discriminate between diseased, healthy and apparently healthy leaves by applying PCA to HPLC data. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    We report the mineralogy, petrography, and in situ measured 26Al-26Mg systematics in chondrules from the least metamorphosed CV3 (Vigarano-type) chondrites, Kaba and Yamato (Y) 980145. Two Y 980145 chondrules measured show no resolvable excesses in 26Mg (26Mg∗), a decay product of a short-lived (t1/2 ∼0.7 Ma) radionuclide 26Al. Plagioclase in one of the chondrules is replaced by nepheline, indicative of thermal metamorphism. The lack of 26Mg∗ in the Y 980145 chondrules is most likely due to disturbance of their 26Al-26Mg systematics during the metamorphism. Although Kaba experienced extensive metasomatic alteration (core in this body suggested from the paleomagnetic records of Allende [Carporzen et al.

    Recent paleomagnetic studies of Allende CV chondrite as well as thermal modeling suggest the existence of partially differentiated asteroids with outer unmelted and variably metamorphosed crusts overlying differentiated interiors. To further constrain the magnetic history of the CV parent body, we report here paleomagnetic results on Kaba CV chondrite. This meteorite contains 11 wt% pseudo-single domain magnetite, making it a rock with an excellent paleomagnetic recording capacity. Kaba appears to carry a stable natural remanent magnetization acquired on its parent body upon cooling in an internally generated magnetic field of about 3 μT from temperatures below 150 °C during thermal metamorphism about 10 to several tens of Myr after solar system formation. This strengthens the case for the existence of a molten advecting core in the CV parent body. Furthermore, we show that no significant magnetic field (i.e. lower than ∼ 0.3 μT) was present when aqueous alteration took place on the Kaba parent body around 4 to 6 Myr after solar system formation, suggesting a delay in the onset of the dynamo in the CV parent body and confirming that nebular fields had already decayed at that time.

The apparent chemical diffusion coefficients of lithium in the films, D-tilde{sub Li}, were measured by cyclic voltammetry (CV), galvanostatic intermittent titration technique (GITT), and electrochemical impedance spectroscopy (EIS). The average D-tilde{sub Li} values calculated from CV results were in the order of 10{sup -14} cm{sup 2} s{sup -1}. The D-tilde{sub Li} values obtained by GITT, and EIS techniques were in the range of 10{sup -14}-10{sup -18} cm{sup 2} s{sup -1}, 10{sup -14}-10{sup -18} cm{sup 2} s{sup -1}, respectively. The D-tilde{sub Li} values obtained by the two methods show a minimum point at x {approx} 0.5 for Li{sub 1-x}FePO{sub 4}. However, the overpotential values of the LiFePO{sub 4} thin film electrodes obtained from the GITT results and the diffusion impedance deduced from the impedance spectra also show the minimum values at x {approx} 0.5 for Li{sub 1-x}FePO{sub 4}. This contradict could be caused by the improper use of GITT and EIS techniques for measuring the chemical diffusion coefficient of Li in Li{sub 1-x}FePO{sub 4} which constitutes two phase, i.e., LiFePO{sub 4} and FePO{sub 4} in this region.

    This paper presents a direct comparison between two satellite time transfer techniques: common-view (CV) of satellites from the global positioning system (GPS) constellation, and time transfer by laser link (T2L2) through the low orbiting satellite Jason-2. We describe briefly both techniques, together with two independent relative calibration campaigns of the links involving four European laboratories. Between the same remote time scale reference points, the mean values of the calibrated differences between GPS CV and T2L2 are below 240 ps, with standard deviations below 500 ps, mostly due to GPS CV. Almost all sample deviations from 0 ns are within the combined uncertainty estimates. Despite the relatively small number of common points obtained, due to the fact that T2L2 is weather dependent, these results provide an unprecedented sub-ns consistency between two independently calibrated microwave and optical satellite time transfer techniques.

    There are several leading theories on the processes that led to the formation of chondrites, e.g., sorting by mass, by X-winds, turbulent concentration, and by photophoresis. The juxtaposition of refractory inclusions (CAIs) and less refractory chondrules is central to these theories and there is much to be learned from their relative size distributions. There have been a number of studies into size distributions of particles in chondrites but only on relatively small scales primarily for chondrules, and rarely for both Calcium Aluminum-rich Inclusions (CAIs) and chondrules in the same sample. We have implemented macro-scale (25 cm diameter sample) and high-resolution microscale sampling of the Allende CV3 chondrite to create a complete data set of size frequencies for CAIs and chondrules.

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.

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 altitudinal variation of the contents of secondary metabolites in flowering heads of Matricaria chamomilla L. (Asteraceae) was assessed. Plants of M. chamomilla cultivar BONA were grown in nine experimental plots at altitudes between 590 and 2,230 m at Mount Patscherkofel near Innsbruck/Austria. The amounts of flavonoids and phenolic acids were quantified by HPLC/DAD. For both flavonoids and phenolic acids positive (r = 0.559 and 0.587) and statistically significant (both p < 0.001) correlations with the altitude of the growing site were observed. The results are compared to previous results on Arnica montana L. cv. ARBO. Moreover, various ecological factors, which change with the altitude of the growing site, are discussed as potential causes for the observed variation.

    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.

    Four experiments examined the effect of shared skeletal structure versus content overlap on naming printed nonwords. Experiments 1-2 compared priming among nonwords sharing either skeletal structure and content (e.g., dus-DUS) or structure alone (e.g., pid-BAF) with controls that differed from the target in the number of skeleton slots (e.g., pid-BAF vs. plid-BAF). Conversely, in Experiments 3-4, same-versus different-structure primes contrasted only in the ordering of CV skeletal slots (e.g., fap-DUS vs. ift-DUS). Priming effects were modulated by shared content and skeletal similarity. The sensitivity of skeletal priming to the abstract arrangement of consonants and vowels suggests that skeletal representations assign distinct slots for consonants and vowels. Readers' sensitivity to skeletal structure in nonword identification indicates that assembled phonological representations are constrained by linguistic knowledge.

    2005-07-01

    Two new ursolic acid triterpene derivatives, compounds 2 and 3, have been isolated from cv. Annurca apple fruit, a high-quality apple variety widely cultivated in southern Italy, together with the known 2-oxopomolic acid (1). The new compounds were identified by means of different spectroscopic techniques as 3-epi-2-oxopomolic acid (= (3alpha)-3,19-dihydroxy-2-oxours-12-en-28-oic acid; 2) and (1alpha)-1-hydroxy-3-oxours-12-en-28-oic acid (3). Compounds 1-3 were tested for their radical-scavenging activities with the aid of a 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay (Fig. 2). All three constituents showed activities similar to that of the reference antioxidant alpha-tocopherol (vitamin E).

    Full Text Available An efficient method for genetic transformation and shoot regeneration was achieved in bird's foot trefoil cv. Bokor using A. rhizogens. The transformed shoots were regenerated on hairy root segments in high frequency. After rooting and acclimation, transformed To plants were grown in experimental field. Analysis of morphological traits and chemical content in ten unintentionally chosen To bird's foot trefoil plants (genotypes no. 2 and no. 5 was performed. They were compared to those of control non-transformed plants. The traits as a number of stems per plant, length of internodes in longest stem, number of flowers per plant and plan high were very significant differed than the same traits in control plants, while there were no significant differences in the leaf area. No signs of the rol genes genotype and "T" phenotype were present. The transformed plants had significantly higher content of cellulose, while the protein and nitrogen contents of are in the range of control plants.

    The cooling and ventilation group deals with a great number of supplies and installation contracts, as well as some service ones, in relation to the LHC project. In the course of the last years the group has increased its experience in the handling of these contracts in particular as a consequence of the difficult situations sometimes faced, which have been trying but enriching. This paper reviews some statistics on the performance of the CV contracts and draws some conclusions from a set of key cases. These cases can be helpful in identifying possible weak points during the different project phases (engineering, tendering and contracting, installation, etc.) and can provide a basis for the discussion of potential solutions.

    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.

    2014-03-01

    Thomas Jefferson National Accelerator Facility (TJNAF) uses superconducting radiofrequency (SRF) cavities to accelerate an electron beam. If theses cavities have a small particle or defect, it can degrade the performance of the cavity. 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.

    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 microM alpha-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 microM was economically better.

    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.

    2014-09-15

    Grapes (Vitis vinifera, cv Sangiovese), harvested at standard commercial maturity, were treated for 36 h with ethylene (ET, 1000 ppm) or air (control, CT) before vinification. The composition of the grapes, must and wine was different in the CT and ET samples. In the ET wine, higher concentrations of specific phenol compounds, belonging to the classes of flavonols, anthocyanins, flavan-3-ols, and stilbenes, were detected. ET induced a significant change in the wine aroma profile by increasing free volatile categories such as phenols and fatty acids, and reducing the content of carbonyl compounds and, in particular, of esters. Less pronounced differences between CT and ET wines were observed in terms of glycosidically-bound volatile compounds. The activity of pectin methyl esterase and β-glucosidase was enhanced in ET-treated berry skins, suggesting that cell wall properties and changes in the hydrolytic activity are effective in modulating the composition of CT and ET wines.

    Three multiple forms of polygalacturonase (PG) namely PGI, PGII and PGIII were isolated, purified and characterized from ripe mango (Mangifera indica cv. Dashehari) fruit. Native molecular weights of PGI, PGII and PGIII were found to be 120, 105 and 65kDa, respectively. On SDS-PAGE analysis, PGI was found to be a homodimer of subunit size 60kDa each while those of PGII and PGIII were found to be heterodimers of 70, 35 and 38, 27kDa subunit size each, respectively. Three isoforms of PG differed with respect to the effect of pH, metals, reducing agents and their susceptibility towards heat. PG isoforms also differed with respect to the effect of substrate concentration on enzyme activity. PGI and PGIII exhibited inhibition at high substrate concentration while PGII did not. Km for polygalacturonic acid was found to be 0.02% for PGI.

    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.

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

    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.

    Cell suspension cultures of bean (Phaseolus vulgaris) cv. Imuna accumulated isoflavonoid phytoalexins on exposure to elicitor from the phytopathogenic fungus Colletotrichum lindemuthianum (CL). This was preceeded by rapid increases in the activities of phenylalanine ammonia-lyase (PAL) and chalcone synthase (CHS). However, the patterns of expression of PAL and CHS genes differed from those observed in cultures of a previously studied bean cultivar. The relative levels of transcripts from individual members of the CHS multigene family differed significantly at 1.5 h compared to 22.5 h after elicitation. More strikingly, three PAL genes were expressed in cultivar Imuna in response to fungal elicitor, whereas two are expressed in elicitor-treated cell cultures of cultivar Canadian Wonder.

  1. Chemical and physical studies of type 3 chondrites 12: The metamorphic history of CV chondrites and their components

    Guimon, R. Kyle; Symes, Steven J. K.; Sears, Derek W. G.

    1995-01-01

    The induced thermoluminescence (TL) properties of 16 CV and CV-related chondrites, four CK chondrites and Renazzo (CR2) have been measured in order to investigate their metamorphic history. The petrographic, mineralogical and bulk compositional differences among the CV chondrites indicate that the TL sensitivity of the approximately 130 C TL peak is reflecting the abundance of ordered feldspar, especially in chondrule mesostasis, which in turn reflects parent-body metamorphism. The TL properties of 18 samples of homogenized Allende powder heated at a variety of times and temperatures, and cathodoluminescence mosaics of Axtell and Coolidge, showed results consistent with this conclusion. Five refractory inclusions from Allende, and separates from those inclusions, were also examined and yielded trends reflecting variations in mineralogy indicative of high peak temperatures (either metamorphic or igneous) and fairly rapid cooling. The CK chondrites are unique among metamorphosed chondrites in showing no detectable induced TL, which is consistent with literature data that suggests very unusual feldspar in these meteorites. Using TL sensitivity and several mineral systems and allowing for the differences in the oxidized and reduced subgroups, the CV and CV-related meteorites can be divided into petrologic types analogous to those of the ordinary and CO type 3 chondrites. Axtell, Kaba, Leoville, Bali, Arch and ALHA81003 are type 3.0-3.1, while ALH84018, Efremovka, Grosnaja, Allende and Vigarano are type 3.2-3.3 and Coolidge and Loongana 001 are type 3.8. Mokoia is probably a breccia with regions ranging in petrologic type from 3.0 to 3.2. Renazzo often plots at the end of the reduced and oxidized CV chondrite trends, even when those trends diverge, suggesting that in many respects it resembles the unmetamorphosed precursors of the CV chondrites. The low-petrographic types and low-TL peak temperatures of all samples, including the CV3.8 chondrites, indicates metamorphism

    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.

    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. Snežná hydroxycinnamic derivatives rosmarinic acid luteolin-7-O-glucoside DPPH.

    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.

    Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was used to measure distributions of the siderophile elements V, Fe, Co, Ni, Mo, Ru, Rh, Pd, W, Re, Os, Ir, Pt, and Au in Fremdlinge with a spatial resolution of 15 to 25 μm. A sulfide vein in a refractory inclusion in Allende (CV3-oxidized) is enriched in Rh, Ru, and Os with no detectable Pd, Re, Ir, or Pt, indicating that Rh, Ru, and Os were redistributed by sulfidation of the inclusion, causing fractionation of Re/Os and other siderophile element ratios in Allende CAIs. Fremdlinge in compact Type-A inclusions from Efremovka (CV3-reduced) exhibit subsolidus exsolution into kamacite and taenite and minimal secondary formation of V-magnetite and schreibersite. Siderophile element partitioning between taenite and kamacite is similar to that observed previously in iron meteorites, while preferential incorporation of the light PGEs (Ru, Rh, Pd) relative to Re, Os, Ir, and Pt by schreibersite was observed. Fremdling EM2 (CAI Ef2) has an outer rim of P-free metal that preserves the PGE signature of schreibersite, indicating that EM2 originally had a phosphide rim and lost P to the surrounding inclusion during secondary processing. Most Fremdlinge have chondrite-normalized refractory PGE patterns that are unfractionated, with PGE abundances derived from a small range of condensation temperatures, ˜1480 to 1468 K at P tot = 10 -3 bar. Some Fremdlinge from the same CAI exhibit sloping PGE abundance patterns and Re/Os ratios up to 2 × CI that likely represent mixing of grains that condensed at various temperatures.

    We estimate the economic value of the natural environment damaged in the Seto Inland Sea after the introduction of the Law on Temporary Measures for the Environmental Conservation of the Seto Inland Sea (Setouchi Law) and the value of the natural environment that survived, using a Contingent Valuation (CV) survey on an Internet web site. The CV survey contains three plans. Plan 1 is to restore 4 ha of reclaimed land. By estimating the Willingness To Pay (WTP) for plan 1, we can appraise the value of the natural environment that was damaged as a result of the original reclamation. Plan 2 is to transplant Zostera (eel-grass) into an area of 10 ha offshore. Plan 3 is to preserve the shore area, a natural habitat for rare animal species, under the National Trust Program. From the WTP for plans 2 and 3, we can estimate the value of the shore area and the areas a little farther offshore. The value of the natural environment damaged in the Seto Inland Sea as a result of reclaiming projects after the introduction of the Setouchi Law and the value of the existing natural environment of the Seto Inland Sea from the WTP for the plans were estimated to about 172 trillion yen (1.46 trillion dollars) and about 424 trillion yen (3.60 trillion dollars), respectively. The results indicate that in the 25 years since the introduction of the Setouchi Law, we have degraded every year about 6.88 trillion yen (58.5 billion dollars) worth of the natural environment by reclaiming. Some seaweed farms and natural shore areas, natural habitats to rare marine life-forms like the horseshoe crab and the fiddler crab have survived, but their value amounts to about 80% of Japan's GDP.

    Full Text Available ‘Topaz’ is a modern Czech apple cultivar well accepted by consumers and scab-resistant, providing reasons for the significant spreadof cv. ‘Topaz’ in European orchards, especially in the organic fruit production industry. Growing the apple trees on their own rootsprovides some advantages in comparison with grafted trees. Micropropagation is the method of choice for plantlet production for thispurpose as well as for the establishment of healthy mother stock trees as a source of scions. The efficiency of axillary shoot proliferationwas examined on four media differing in plant growth regulators and their concentrations, and from three explant types: intact ordecapitated and defoliated microshoots placed vertically and one-nodal segments placed horizontally. All media consisted of Quoirin andLepoivre (QL macroelements and Murashige and Skoog (MS microelements. Furthermore, rooting efficiency on six different media/treatments was analyzed. Media with 1 mg/L 6-benzylaminopurine (BA or BA (0.5 mg/L + 1.5 mg/L kinetin (Kin produced similarnumber of microshoots per inoculated one (2.5 and 2.4, respectively. Medium with 1 mg/L thidiazuron (TDZ produced significantlyhigher number of shoots (3.6 but they were fasciated. Three different explant types also produced similar numbers of microshoots.High rooting efficiency (68.7%, a high number of roots per shoot (6.6 and the best quality of shoots were obtained in rooting mediumcontaining 2 mg/L of indole-3-butyric acid (IBA. An efficient method of shoot proliferation was established, and, since rooting was themost critical step, an efficient procedure for rooting apple cv. ‘Topaz’ was established.

    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.

    Full Text Available O objetivo do presente trabalho foi otimizar um protocolo de regeneração de explantes cotiledonares de melão, cultivar 'Gaúcho', avaliando a composição de meios de germinação e o tempo de permanência dos explantes nesses meios. 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.

Para melhor compreesão do crescimento do dossel, realizou-se também análise do crescimento, estimando-se a taxa de crescimento relativo (TCR, a taxa assimilatória líquida (TAL e a razão de área foliar (RAF da gramínea. Para todas as variáveis, foram consideradas estimativas semanais, realizadas aos 7º, 14º, 21º, 28º, 35º, 42º e 49º dias de rebrotação da gramínea, após pastejo de uniformização. Utilizou-se delineamento experimental inteiramente casualizado, com quatro repetições e duas áreas experimetais: uma no verão e outra no outono. No verão e no outono, foram visualizados, respectivamente, 28 e 24 pontos, sorteados pelos tratamentos experimentais, semelhantes quanto à altura do dossel e à cobertura do solo, após intenso pastejo de uniformização. O perfilhamento da gramínea, intenso na primeira semana, decresceu nas duas semanas seguintes e praticamente cessou a partir da quarta semana. A IRFA evoluiu assintoticamente, atingindo valores de 96% em ambas as estações. O IAF apresentou o mesmo padrão de resposta, com valores de 8 e 4 no verão e no outono, respectivamente. Em ambas as estações, a biomassa evoluiu de forma quadrática com o decorrer da rebrotação. A EUR, mais alta no verão que no outono, decreceu e seus respectivos valores foram 1,76 e 0,54gMS/MJ, em razão da menor precipitação pluviométrica desse período. A eficiência de crescimento do dossel, medida pela TCR, mais alta no verão que no outono e decresceu assintoticamente durante a rebrotação, em ambos os períodos. Enquanto a TAL reduziu durante o período de rebrotação, a RAF aumentou até um ponto de máximo, tanto no verão como no outono

    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 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.

    Objective: To investigate the efficacy of external application of Eleutherosides ointment on Shenque (CV 8) for treating sleep deprivation. Methods: Twenty four healthy young male volunteers at the age of 19-22 years old were randomly allocated to 4 groups (normal, model, treatment and control groups). Sleep was deprived for 48 hours except the normal group. Self-made Eleutherosides compound preparation was applied externally on Shenque (CV 8), to observe its influence on psychology and blood biochemical indices of cortisol and testosterone of the human body in sleep deprivation. Results: After sleep deprivation for 48 hours, an increment in cortisol concentration was lower in the Eleutherosides group (44.482 ± 96.065 nmol/L) than in the control group (146.809 ± 71.075 nmol/L); an increment in the self-evaluated depression scale was also lower in the Eleutherosides group (2.833 ± 16.746) than in the control group (20.417 ± 10.358). There were significant differences (P<0.05). But, there was no significant difference between the treatment group and control group (P>0.05) in the decrement of testosterone concentration and the increment of the anxiety scale. Conclusion: External application of Eleutherosides preparation on Shenque (CV 8) can regulate the stress reaction level and psychological endurance of the human body and produce an effect to resist sleep deprivation.%目的:观察刺五加总甙神阙穴位贴敷疗法的抗睡眠剥夺作用.方法:健康青年男性19~22岁)志愿者24名,完全随机分为4组(正常组、模型组、处理组、对照组),除正常组外剥夺全部睡眠48 h,以自制刺五加总甙复方制剂于神阙穴处贴敷,观察其对睡眠剥夺人体的心理影响以及对皮质醇、睾酮等血液生化指标的影响.结果:48 h睡眠剥夺后,刺五加总甙穴位贴敷皮质醇浓度增高值(44.482±96.065 nmol/L)低于对照组增高值(146.809±71.075 nmol/L),自评抑郁量表增加值(2.833±16.746)

    Full Text Available A rosa é considerada uma das flores de corte mais tradicionais e requisitadas no mercado mundial. Entretanto, após o corte, essas flores tornam-se altamente perecíveis devido à elevada atividade metabólica que conduz aos processos de senescência. Assim, o experimento foi realizado para verificar o efeito do uso de soluções conservantes na fisiologia pós-colheita de rosas vermelhas cortadas cultivar Vega. Utilizou-se o delineamento inteiramente casualizado, em esquema fatorial composto por dois fatores: sete tratamentos pós-colheita e quatro datas de avaliação. As flores permaneceram nas seguintes soluções de manutenção: 1 Água destilada; 2 8-hidroxiquinolina (200 mg L-1; 3 8-hidroxiquinolina (200 mg L-1 + Sacarose (20 mg L-1; 4 Ácido cítrico (75 mg L-1; 5 Ácido cítrico (75 mg L-1 + Sacarose (20 mg L-1; 6 6-benziladenina (60 mg L-1; 7 6 benziladenina (60 mg L-1 + Sacarose (20 mg L-1. Foram realizadas análises qualitativas e fisiológicas ao longo do período de avaliação. O tratamento com 8-hidroxiquinolina e ácido cítrico revelaram-se mais promissores para manter a qualidade e prolongar a vida de vaso das flores, o que foi evidenciado pela menor perda de massa fresca, atividade respiratória e conteúdo relativo de água; melhor manutenção do conteúdo de carboidratos solúveis e redutores, antocianina e coloração.The rose is considered one of the most traditional and required cut flowers in the world market.

    This research aimed to develop a protocol for the micropropagation of Mussaenda erytrophylla cv. Rosea. Calcium hypochlorite or sodium hypochlorite (2.5% was used for the sterilization of bracts segments, with or without previous immersion in alcohol 70%. For callus induction, bracts segments were inoculated on MS medium with different concentrations of BAP and NAA. For buds induction, callus were inoculated on MS medium with different concentrations of cytokinins BAP, 2iP, and KIN (0.0 mg L-1, 0.5 mg L-1, 1.0 mg L-1, and 2.0 mg L-1. For multiplication, nodal segments from in vitro plants were inoculated in MS medium with BAP, KIN, and 2iP, in the concentrations of 0.0 mg L-1, 0.5 mg L-1, 1.0 mg L-1, and 2.0 mg L-1. For rooting, nodal segments from in vitro plants were inoculated using two MS medium dilutions: full strength and half strength of MS basal salt mixture (macronutrients salts and different concentrations of IBA (0.00 mg L-1, 0.25 mg L-1, 0.50 mg L-1, and 1.00 mg L-1. The best sterilization treatment was achieved by using calcium hypochlorite combined with immersion in alcohol. For callus induction, the MS medium with 0.4 mg L-1 of NAA plus 4.0 mg L-1 of BAP was more efficient. Bud multiplication was improved in MS medium with 0.5 mg L-1 of 2iP or 1.0 mg L-1 of KIN. The highest percentage of explants with roots without emission of callus was observed in the medium with 50% and 100% of MS salts without IBA.

    The Hass avocado tree Persea americana cv. Hass was derived from a single hybrid tree of P. americana var. drymifolia and P. americana var. guatemalensis, and it is propagated clonally by grafting. This cultivar is the most widely planted in the world but its profile of secondary metabolites has been studied rarely despite of its importance in plant protection. We illustrate the variability of the volatilome of mature leaves by describing the average chemical composition and the phenotypic variability found in 70 trees. Contrary to the uniformity expected in the Hass cultivar, high variability coefficients were found for most of the 36 detected foliar volatile compounds; furthermore we found six chemotypes grouping the foliar phenotypes of the sampled trees using hierarchical cluster analysis. About 48% of trees were grouped in one chemotype; five chemotypes grouped the remaining trees. The compounds that determined these chemotypes were: estragole, α-farnesene, β-caryophyllene, germacrene D, α-cubebene and eugenol. This striking variation in a cultivar propagated clonally is discussed in terms of somatic mutation.

    Full Text Available Chrysanthemum (Dendranthema grandiflorum cv. Jinba shoot branching is determined by bud outgrowth during the vegetative growth stage. The degree of axillary bud outgrowth is highly influenced by environmental conditions, such as nutrient availability. Here, we demonstrated that phosphorus (Pi starvation significantly reduces axillary bud outgrowth in chrysanthemum. A strigolactone (SL biosynthesis gene, DgCCD7, was isolated and characterized as an ortholog of MAX3/DAD3/RMS5/D17. By using ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS, three putative SLs were identified and detected strong induction under Pi starvation conditions. Determinations of the distribution of SLs and negative regulation of DgCCD7/8 time-course in root indicated systemic response of SL. However, temporal expression patterns of biosynthesis and signaling genes in nodes revealed that Pi starvation causes a local response of SL pathway. Application of modified node segments treated with or without auxin and Pi revealed that in the absence of exogenous auxin, Pi delay axillary buds outgrowth and up-regulating local SL pathway genes. These data indicate that an auxin-SL regulatory loop respond to Pi starvation for delaying bud outgrowth locally, root biosynthesized SLs are transported acropetally and function in shoot branching inhibition under Pi starvation. We propose that SLs contribute to chrysanthemum shoot branching control in response to Pi-limiting conditions in a systemic way.

    The shelf life of minimally processed potatoes (MPP) is limited by enzyme-catalyzed browning reactions, with the increase in respiration being another factor that affects quality retention of this product. Sulfites are commonly used as effective preservative agents in minimally processing potatoes, but ascorbic acid and citric acid are considered natural sulfite substitutes and more accepted by consumers. The aim of this study was to study the effect of combinations of the preservative agents cited above (sodium metabisulfite 0.1% and 0.5%; citric acid 0.1% and 0.5%; ascorbic acid 0.5%) on the respiration rate of MPP (cv. Monalisa) processed at both ambient and refrigerated temperatures. The results have revealed that there is a significant effect of dipping treatment and temperature on respiration rate of MPP. Sodium metabisulfite (SM) reduces respiratory activity up to 0.8 mL/kg/h. The addition of either citric or ascorbic acid enhanced the effect of SM on the reduction of the respiration rate of MPP. The strongest effect (up to 3.3 mL/kg/h) was observed when a combination of all 3 agents at the higher concentrations was employed at a temperature of 18 degrees C.

    This research was conducted to study the effect of three different sowing dates (15th October, 15th November and 15th December) and two vernalization treatments (5 °C and -20 °C) on leaf structure of Beta vulgaris L. cv. Univers. The obtained data are summarized as follows: The maximum values of the most studied parameters; lower epidermis + spongy tissue thickness, midrib, mesophyll tissue, vascular bundle, collenchymatous tissue and number of xylem vessels per arm were found as a result of 15th October sowing date treatment compared with the two other sowing dates. Furthermore, effect of the cooling treatments varied according to the recorded character, sowing date and cooling degree. Most of the vernalization treatments at early sowing dates increased the mesophyll tissue, midrib, number of vascular bundles per transverse section, vascular bundle thickness and number of xylem arms per transverse section. The two studied cooling treatments at 15th October sowing date increased both stomatal index and average number of stomata: average number of epidermis cells compared with the control. Furthermore, 15th October under -20 °C treatment led to small epidermal cells and stomata formation, straight epidermal cell walls and closed stomata in comparison to the control.

    Hemes destined for cytosolic hemoproteins must originate in one of the cellular compartments which have the capacity for heme synthesis, namely the chloroplast or the mitochondria. Since developing chloroplasts from greening cucumber (Cucumis sativus, cv. Sumter) cotyledons are known to contain complete heme and chlorophyll biosynthetic pathways, they were tested for their capacity export hemes. Picomole quantities of heme were measured by reconstitution of the heme with apo-peroxidase and subsequent determination of peroxidase activity. The assay method was sensitive (as little as 0.7 picomole of heme could be detected in a volume of 100 microliters) and was linear with heme concentration. When intact plastids were incubated with apo-peroxidase, a steady-state rate of efflux between 0.12 and 0.45 picomole heme/minute/milligram plastid protein was measured. The efflux rate was not due to plastid breakage and could be enhanced by incubating with the heme precursor, {delta}-aminolevulinic acid. Cold acetone extraction removed 47 {plus minus} 17 picomoles heme/milligram plastid protein from the total b-type heme pool in the chloroplasts (166 {plus minus} 9 picomoles heme/milligram protein, by acid-acetone extraction). The reconstitution technique provided a similar estimate of readily exchangeable heme in the plastid, 37 {plus minus} 8 picomoles heme/milligram protein (or 6 micromolar in the plastids). These values may be indicative of a free heme pool which exists in the chloroplast.

    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.

    Full Text Available ABSTRACT This study aimed to evaluate the effect of nitrogen (N and potassium (K fertilization in yield and contents of macronutrients in heliconia plants (Heliconia psittacorum x Heliconia spathocircinata Aristeguieta cv. Golden Torch. The experiment was set in a randomized block design, in a 4 x 4 factorial, corresponding to N doses (0, 120, 180 and 240 g of N hole-1 and K doses (0, 120, 180 and 240 g of K2O hole-1 with four replicates and five rhizomes per plot, under field conditions. After one year of cultivation, yield (number of flower stems per square meter and the leaf contents of N, P, K, Ca, Mg and S were determined. The applied N doses did not influence either yield or the leaf contents of the evaluated macronutrients. K fertilization favored the increase in leaf K content and the decrease in the contents of P, Ca and Mg in leaves of heliconias. Under the conditions of this experiment, it is recommended to apply 161.46 g of K2O hole-1 for a maximum yield of 9.89 stems m-2 per month.

Scanning electron microscopy revealed that fiber initials were virtually absent from fl ovules. RT-PCR analysis showed that the steady-state levels of transcripts of the fiber-specific E6 and Expansin genes were high in wild type (WT) ovules during the fiber initiation and elongation stages, and peaked around 15 days post anthesis (DPA), but only a trace amount of these transcripts was detectable in fl ovules of alt developmental stages investigated. CotmybA, a member of the Myb family, exhibited a clear expression in developing WT ovules, but the expression was abnormal in fl ovules. Application of GA3, or GA3 plus IAA, to the culture medium rescued in vitro fiber initiation and growth of fl ovules only partially.

RT-PCR analysis showed that the steady-state levels of transcripts of the fiber-specific E6 and Expansin genes were high in wild type (WT) ovules during the fiber initiation and elongation stages, and peaked around 15 days post anthesis (DPA), but only a trace amount of these transcripts was detectable in fl ovules of all developmental stages investigated. CotmybA, a member of the Myb family, exhibited a clear expression in developing WT ovules, but the expression was abnormal in fl ovules. Application of GA3, or GA3 plus IAA, to the culture medium rescued in vitro fiber initiation and growth of fl ovules only partially. In addition, transcription of E6 and Expansin genes of in vitro cultured WT and fl ovules responded similarly to exogenous hormones. The hormones had less effect on CotmybA transcription in ovules cultured in vitro, and again the WT and fl ovules showed a similar expression. These results suggest that the abnormal or extremely low level of expression of E6, Expansin and CotmybA genes in developing fl seeds is related to the absence of seed-hairs, and the mechanism underlying needs further investigation.

    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.

    Full Text Available Malus domestica Borkh. cv Bravo de Esmolfe is a typical Portuguese apple cultivar classified as Protected Designation and Origin (PDO. It is a traditional product produced under strict conditions and labelled with a specific law protected designation. This cultivar presents quite good sweetness and flavor. The monosaccharide composition of the pectic polysaccharides from this traditional apple is herein reported for the first time. Based on the molar ratios obtained from the sugar composition, the presumable pectin structure could be inferred. The cell-wall polysaccharides present in the alcohol-insoluble residue (AIR of unpeeled BE apple were sequentially fractionated. In addition, pectic material was also extracted by citric acid treatment prior to heat extraction at acidic pH. The water soluble pectin, imidazole soluble pectin and sodium carbonate soluble pectin account for 44, 16 and 40 % of the AIR, respectively. The pectic polysaccharides extracted in the presence of citric acid had lower galacturonic acid content and higher neutral sugars content. The homogalacturonan (HG and less-substituted rhamnogalacturonan (RG domains are extracted first. Pectin treated with citric acid has been shown to contain more substituted polymers, especially RG-I. In addition, the relatively higher Xylose/Galacturonic acid ratio found in the citric acid extract demonstrates that the xylogalacturonan (XG domain presumably is present in the pectic material of the unpeeled BE apple.

    Full Text Available The production and number of processed food industries have slightly increased; as a result, the companies must compete to maximize their profits by conducting their efficient production process. CV. Fiva Food is one of the companies in the field of processed foods, especially in processed meat that has implemented supply chain management. It is necessary for the company to take measurements of its performance and efficiency for the entire supply chain such as procurement of raw materials. The purposes of this study were to analyze the performance of the company's supply chain and determine the most efficient  method of procurement for its raw materials as well as and to provide recommendations for the company to improve its performance of entire supply chain. This study used SCOR in analyzing the performance of supply chain and EOQ and POQ method to be compared with the method that the company uses to determine which method of procurement for raw materials is the most efficient one. The result showed that based on the matrix, the company's performance is unfavorable when it was compared to the benchmark performance of inventory days of supply. In addition, this study showed that the POQ method produces the lowest total inventory cost with savings of Rp6.647.015 for raw materials of MDM whereas EOQ method produced the lowest total inventory cost with savings of Rp222.153,78 for raw materials of FQ85CL.

    Full Text Available A lectin has been isolated from seeds of the Phaseolus vulgaris cv. “Anasazi beans” using a procedure that involved affinity chromatography on Affi-gel blue gel, fast protein liquid chromatography (FPLC-ion exchange chromatography on Mono S, and FPLC-gel filtration on Superdex 200. The lectin was comprised of two 30-kDa subunits with substantial N-terminal sequence similarity to other Phaseolus lectins. The hemagglutinating activity of the lectin was stable within the pH range of 1–14 and the temperature range of 0–80∘C. The lectin potently suppressed proliferation of MCF-7 (breast cancer cells with an IC50 of 1.3 μM, and inhibited the activity of HIV-1 reverse transcriptase with an IC50 of 7.6 μM. The lectin evoked a mitogenic response from murine splenocytes as evidenced by an increase in [3H-methyl]-thymidine incorporation. The lectin had no antifungal activity. It did not stimulate nitric oxide production by murine peritoneal macrophages. Chemical modification results indicated that tryptophan was crucial for the hemagglutinating activity of the lectin.

    Full Text Available Yam contributes to energy and nutritional requirements of most of the population of developing countries. However, their extensive culture is constrained by the limited availability of planting material with physiological and sanitary quality, and also part of the harvesting is used as seed in the next planting. For this reason, it is necessary to establish a methodology for plant regeneration and somatic embryogenesis could facilitate their micropropagation and genetic improvement. This study aimed to form embryogenic callus in Dioscorea rotundata Poir cv. `White Guinea'. The effect of the addition of 2,4-dichlorophenoxyacetic acid (2,4-D (0, 1.0, 2.0 and 4.0 mg l-1 was determined, in combination with three types of explants from in vitro plants (leaves petiole, petiole segments and root sections. The highest percentage of embryogenic callus was obtained with 1.0 mg l-1 2,4-D and leaves with petiole as explants. These were characterized by the presence of compact whitish nodules.

    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

    Full Text Available One of the main factors of an aggregate hydroponic system is to use a suitable plant media with local origin. Thus the objective of this research was to study the possibility of replacement of cocopeat as an imported material with local materials and the effects of such media on the growth and flowering characteristics of Rosa hybrida cv. Maroussia. A randomized complete blocks design experiment with four replications was conducted. The treatments were nine growing media: cocopeat (100%, perlite (100%, leca (100%, cocopeat (75% + zeolite (25%, perlite (75% + zeolite (25%, leca (75% + zeolite (25%, cocopeat (50% + perlite (50%, cocopeat (50% + leca (50% and perlite (50% + leca (50%. Results indicated that plants grown in cocopeat and cocopeat + zeolite showed high vegetative and reproductive growth. The highest number of flowers per plant was observed in in cocopeat (8.31 and cocopeat + perlite (7.81 substrates, which had no significant difference with cocopeat + zeolite medium (6.87. Adding zeolite to cocopeat, perlite and leca improved length of flower bud and number of flowers per plant over their pure medium. Also, adding cocopeat to perlite increased fresh and dry weight of cut flowers and number of flowers per plant. Based on the results and availability of zeolite in Iran, mixture of cocopeat (75% + zeolite (25% is recommended.

    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 β{sub p} = –52° ± 6° and β{sub s} = 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 {sub *}) 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 {sub *}. 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.

    The CV3 Allende is one of the most extensively studied meteorites in worldwide collections. It is currently classified as S1-essentially unshocked-using the classification scheme of Stöffler et al. (1991), however recent modelling suggests the low porosity observed in Allende indicates the body should have undergone compaction-related deformation. In this study, we detail previously undetected evidence of impact through use of Electron Backscatter Diffraction mapping to identify deformation microstructures in chondrules, AOAs and matrix grains. Our results demonstrate that forsterite-rich chondrules commonly preserve crystal-plastic microstructures (particularly at their margins); that low-angle boundaries in deformed matrix grains of olivine have a preferred orientation; and that disparities in deformation occur between chondrules, surrounding and non-adjacent matrix grains. We find heterogeneous compaction effects present throughout the matrix, consistent with a highly porous initial material. Given the spatial distribution of these crystal-plastic deformation microstructures, we suggest that this is evidence that Allende has undergone impact-induced compaction from an initially heterogeneous and porous parent body. We suggest that current shock classifications (Stöffler et al., 1991) relying upon data from chondrule interiors do not constrain the complete shock history of a sample.

    In the skin of cv. Napoleon table grapes, the anthocyanins malvidin 3-glucoside (and its acetyl and p-coumaroyl derivatives), cyanidin 3-glucoside, peonidin 3-glucoside, cyanidin 3-glucoside, petunidin 3-glucoside, and delphinidin 3-glucoside were identified by HPLC-DAD-MS. In addition, quercetin 3-glucoside and 3-glucuronide, caffeoyltartaric, piceid, and resveratrol were also detected. The content of most phenolics remained quite constant during postharvest refrigerated storage (10 days at 0 degrees C) while the resveratrol derivatives increased 2-fold. Postharvest treatments of grapes with UVC and UVB light induced a large increase in resveratrol derivatives (3- and 2-fold, respectively). This means that a serving of mature Napoleon grapes (200 g) provides approximately 1 mg of resveratrol, which is in the range of the amount supplied by a glass of red wine. This can be increased to 2 or 3 mg of resveratrol per serving in grapes that have been irradiated with UVB or UVC, respectively. These results show that refrigerated storage and UV irradiation of table grapes can be beneficial in terms of increasing the content of potentially health-promoting phenolics.

  4. Entropy and coefficient of variation (CV as tools for assessing power quality

    2011-10-01

    Full Text Available This paper presents several concepts and techniques for quantifying electric signal entropy and variability for assessing power quality, showing their irregularities, such as the electrical sine wave which delivers power to industry and homes. The paper will review these concepts and show some magnetic radiated waves measurements taken below 115 KV electricity line circuits in the city of Manizales (Colombia through non-invasive and indirect measurement of the complexity of the current transported by the supply. Entropy, as an accepted indicator of physical complexity, is proportional to the logarithm of the number of states in a thermodynamic system. Some writers have identified entropy as being system disorder, but this is not completely true. Entropy of information was first defined by Shannon in 1949 and it is applied to many physical events. Entropy has been used for describing the complexity of the magnetic wave radiated by the line in this paper. Furthermore, the magnetic waves’ spectral and amplitude coefficient of variation (CV were obtained using a multiresolution wavelet algorithm which measures data distribution dispersion. It is a dimensionless number allowing the variation of magnetic radiated data having significantly different mean values to be compared to a 60 Hz pure magnetic wave as reference.

    The relationships between variations in grapevine (Vitis vinifera L. cv. Pinot noir) growth and resulting fruit and wine phenolic composition were investigated. The study was conducted in a commercial vineyard consisting of the same clone, rootstock, age, and vineyard management practices. The experimental design involved monitoring soil, vine growth, yield components, and fruit composition (soluble solids, flavan-3-ol monomers, proanthocyanidins, and pigmented polymers) on a georeferenced grid pattern to assess patterns in growth and development. Vine vigor parameters (trunk cross-sectional area, average shoot length, and leaf chlorophyll) were used to delineate zones within both blocks to produce research wines to investigate the vine-fruit-wine continuum. There was no significant influence of vine vigor on the amount of proanthocyanidin per seed and only minimal differences in seed proanthocyanidin composition. However, significant increases were found in skin proanthocyanidin (mg/berry), proportion of (-)-epigallocatechin, average molecular mass of proanthocyanidins, and pigmented polymer content in fruit from zones with a reduction in vine vigor. In the wines produced from low-vigor zones, there was a large increase in the proportion of skin tannin extracted into the wine, whereas little change occurred in seed proanthocyanidin extraction. The level of pigmented polymers and proanthocyanidin molecular mass were higher in wines made from low-vigor fruit compared to wines made from high-vigor fruit, whereas the flavan-3-ol monomer concentration was lower.

    I-Xe analyses were carried out for chondrules and refractory inclusions from the two CV3 carbonaceous chondrites Mokoia and Vigarano (representing the oxidized and reduced subgroups, respectively). Although some degree of disturbance to the I-Xe system is evident in all of the samples, evidence is preserved of aqueous alteration of CAIs in Mokoia 1 Myr later than the I-Xe age of the Shallowater standard and of the alteration of a chondrule (V3) from Vigarano ~0.7 Myr later than Shallowater. Other chondrules in Mokoia and Vigarano experienced disturbance of the I-Xe system millions of years later and, in the case of one Vigarano chondrule (VS1), complete resetting of the I-Xe system after decay of essentially all 129I, corresponding to an age more than 80 Myr after Shallowater. Our interpretation is that accretion and processing to form the Mokoia and Vigarano parent bodies must have continued for at least 4 Myr and 80 Myr, respectively. The late age of a chondrule that shows no evidence for any aqueous alteration or significant thermal processing after its formation leads us to postulate the existence of an energetic chondrule-forming mechanism at a time when nebular processes are not expected to be important.

    The foliar fertilization has been used as an important agrotechnical measure to avoid deficiencies and to improve quality. During the two consecutive years, a study has been performed on Vitis vinifera L. (cv. 'Cardinal') to examine whether a grape berry quality has been affected by the foliar application of PK fertilizer. A liquid mineral fertilizer containing 15% P2O5, 20% K2O with 0.1% B, 0.1% Mn and 0.01% Mo (% w/w) has been sprayed three times at rate of 8 L ha(-1) every 14-15 days starting at about 15 days before veraison. The sugars, organic acids and flavonoids (anthocyanins, flavonols and flavan-3-ols) have been analyzed by the high performance liquid chromatography in the grape berries. The foliar fertilization of grapevine can accelerate the accumulation of sugars and anthocyanins, whereas climatic factors and yearly fluctuations influence the content of sugars, organic acids, and phenolic compounds in general. The effect of fertilizer spraying on flavonols and flavan-3-ols has not been found.

    The Effort to increase rice production is often constrained by pest and disease such as Tungro. The Tungro disease is caused by the joint infection with two dissimilar viruses; a bacil-form-DNA virus, the Rice tungro bacilliform virus(RTBV) and the spherical RNA virus, Rice tungro spherical virus (RTSV) and transmitted by Green leafhopper (Nephotettix virescens). The symptom of disease is caused by the presence of RTBV. The genome of RTBV consists of four Open reading frames (ORFs) which encode functional proteins. Of the four, ORF IV is unique because it exists only in RTBV. The most efficient method of generating disease resistance plants is to look for natural sources of resistance genes in wild or germplasm and then transfer the gene and the accompanying resistance in cultivated crop varieties. The aim of this study is, therefore, to isolate and analyze of 1170 bp gene of ORF 4 of Tungro virus isolated from an Indonesian rice cultivar, Ciherang (Oryza sativa L. cv Indica). DNA sequencing analysis using BLAST showed 94% similarity with the reference sequence gen bank Acc.M65026.1. The comparisons and mutation analysis of DNA sequences were discussed in this research.

    Full Text Available Development of drought resistant cotton cultivars has long been a major breeding objective, since water stress limits fiber production and productivity. Recent advances in functional genomics can increase the efficiency of conventional breeding for genetic improvement of crop plants for improved abiotic stress resistance. To this end, a novel drought resistance gene was identified by comparing the gene expression profile of Gossypium hirsutum cv KC3 and MCU12 by employing a cDNA-RAPD approach. Physiological and biochemical studies showed that KC3 has relatively better drought tolerance than MCU12. Among 25 random primers, OPA15 has identified differentially expressed cDNA in KC3. Results of BLASTP algorithm have shown that this cDNA has significant homology with P-Glycoprotein, ACC oxidase2 and ABC transporter which are involved either directly, or indirectly, in stress tolerance in animals and plants. Hence, the cDNA sequence identified in this study may be a novel gene that confers drought resistance in cotton as KC3 is well adapted and is widely cultivated in rain-fed tracts of Tamil Nadu, India. Further characterization of this gene may show it has potential application for development of cotton with improved drought resistance, through genetic engineering and/or marker aided selection (MAS

    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.

    Little is known on structure-activity relationships of antioxidant anthocyanins. Raphanus sativus cv Sango sprouts are among the richest sources (270 mg/100 g fresh weight). We isolated from sprouts' juice 9 acylated anthocyanins, including 4 new compounds. All comprise a cyanidin core bearing 3-4 glucose units, multiply acylated with malonic and phenolic acids (ferulic and sinapic). All compounds were equally effective in inhibiting the autoxidation of linoleic acid in aqueous micelles, with rate constant for trapping peroxyl radicals kinh=(3.8 ± 0.7) × 10(4)M(-1)s(-1) at 37 °C. In acetonitrile solution kinh varied with acylation: (0.9-2.1) × 10(5)M(-1)s(-1) at 30 °C. Each molecule trapped a number n of peroxyl radicals ranging from 4 to 7. Anthocyanins bearing sinapic acid were more effective than those bearing the ferulic moiety. Under identical settings, deacylated cyanin, ferulic and sinapic acids had kinh of 0.4 × 10(5), 0.3 × 10(5) and 1.6 × 10(5)M(-1)s(-1) respectively, with n ranging 2-3. Results show the major role of acylation on antioxidant performance.

    Folates are essential micronutrients for humans, and their deficiency causes several detrimental effects on human health. Papaya fruit is an important natural source of some micronutrients. This paper presents a first complete characterization of folate derivatives accumulated in cv. Maradol papaya during fruit development and ripening processes. During postharvest ripening, the fruit accumulated up to 24.5% of the daily folate recommended dietary allowance (RDA) for an adult in a 1 cup (145 g) portion. Tetrahydrofolate (THF) and 5-methyl-THF were the predominant folate classes observed. Surprisingly, an unusually long polyglutamylation profile of tentatively up to 17 glutamates linked to 5-methyl-THF was detected; to the authors' knowledge, this very long polyglutamyl tail has not been reported for any organism, and it is probably characteristic of this plant species. This polyglutamylation degree changed throughout fruit development and ripening, showing the largest differences at the onset of ripening. This work raises questions about the functional role of folate derivatives in fruit development.

    Food and agricultural industries generate substantial quantities of phenolic-rich by-products that could be valuable natural sources of antioxidants. The aim of this study was to identify and quantify the phenolic compounds and radical scavenging activities of two by-products (pomace and lees) from Vitis vinifera L. cv Pinot noir. We found a different distribution of phenolic classes (flavanols, flavonols, phenolic acids and stilbenes) and singular scavenging activity against free radicals (hydroxyl, superoxide and peroxyl radicals). The major class of phenolics in pomace was flavanols and in lees was flavonols, with catechin (117.9 ± 2.5 μg g(-1)) and quercetin (42.4 ± 1.2 μg g(-1)) being the most abundant individual compounds. We also found high potential on scavenging activity against superoxide radicals in pomace (80% of scavenging activity) and radical peroxyl (67% scavenging activity). These results show the possibility of using Pinot noir by-products as promising additives or as a source for the development of new products in different segments of the food and cosmetic industries.

    Chemical and spectroscopic analyses ((13)C cross-polarization-magic angle spinning NMR and attenuated total reflection Fourier transform infrared spectroscopies) were carried out on the wood of Vitis vinifera cv. Sangiovese with brown-red discoloration and black streaks caused by esca disease. The analyses of the brown-red wood revealed the destruction of hemicelluloses and noncrystalline cellulose as well as modifications in the pectic and ligninic wood fractions. The pectic fraction consisted of carbohydrates associated with polyphenols. The lignin fraction exhibited only a few changes in the aromatic systems and a partial demethylation, and it appeared to be associated with condensed phenolic components probably arising from response polyphenols. The degradation of hemicelluloses and noncrystalline cellulose in brown-red wood, where the pathogens Phaeoacremonium aleophilum and Phaeomoniella chlamydospora prevail with respect to the other fungus Fomitiporia mediterranea, was consistent with reports on the degradative activity of such fungi in vitro carried out on model substrates. The observed alterations could also be attributed to the radical oxidation process caused by the oxidative response of defense itself triggered by infection, as suggested by the accumulation of postinfectional compounds. The analyses of wood tissue with black streaks showed less marked deterioration; here, an increase in pectic and phenolic substances, which probably accumulate in the xylem vessels as a response to the infection, was observed.

    Full Text Available Lettuce is the most popular of the leafy vegetables. It is known worldwide and its consumption occurs mainly in the natural form. The objective was to evaluate the effect of macronutrient omission on the growth and nutritional status of the lettuce cv. Veronica, and to describe the visual symptoms of nutritional deficiency. The treatments complete consisted of the solution and the individual omission of N, P, K, Ca, Mg and S, under a completely randomized design with three replications. Plants were grown in Hoagland & Arnon, in pots (8L. At 56 days after transplant we evaluated plant height, leaf number, leaf area, SPAD index, dry matter of shoots, roots and whole plant, levels of macronutrients in shoots and roots, and the nature of nutritional disorders. The omission of nutrients affected the growth variables. The nutrients found in lettuce plants from nutrient solution and the complete omission in the shoot were, respectively, N= 23.2 to 9.5, P= 5.4 to 1.3, K= 58,9 to 3.2, Ca= 12.1 to 3.6, Mg= 5.5 to 0.7 and S= 3.2 to 1.5g.kg-1. The omission of macronutrients caused quality losses, since it affected the nutrition of the vegetables and this resulted in morphological changes, reflected as symptoms of deficiency for each nutrient.

    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.

    Full Text Available Grazing strategy is a key element in the determination of sward structure, herbage nutritive value and animal performance. We aimed to compare the herbage characteristics and performance of livestock in pastures of Panicum maximum cv. Tanzania managed, using two rotational stocking strategies, which provided either a fixed-length rest period (FRP of 35 days in the spring and fall and 30 days in the summer, or a variable-length rest period (VRP, determined by the time required for the canopy to achieve 70 cm in height. The pastures were evaluated in the pregrazing condition for forage mass (FM; leaf (LP, stem (SP and dead matter (DP percentages; and nutritive value (NV. The animals were weighed every 28 days. Pastures managed with the FRPs exhibited greater FMs, SPs and DPs and lower LPs and NVs than those managed with the VRPs. The average daily livestock weight gain was greater during the spring and summer for the VRP than for the FRP pastures, resulting in an average animal weight gain per area of 990 and 860 kg ha−¹ wet period−¹ for the pastures managed with the VRPs and FRPs, respectively. Thus, pasture rest periods that were maintained after the sward reached 70 cm in height reduced the animal performance on Tanzania guinea grass.

    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.

    Although some works have explored the transformation of differentiated, embryogenic suspension-cultured cells (SCC) to produce transgenic grapevine plants, to our knowledge this is one of the first reports on the efficient transformation of dedifferentiated Vitis vinifera cv Monastrell SCC. This protocol has been developed using the sonication-assisted Agrobacterium-mediated transformation (SAAT) method. A construct harboring the selectable nptII and the eyfp/IV2 marker genes was used in the study and transformation efficiencies reached over 50 independent transformed SCC per gram of infected cells. Best results were obtained when cells were infected at the exponential phase. A high density plating (500 mg/dish) gave significantly better results. As selective agent, kanamycin was inefficient for the selection of Monastrell transformed SCC since wild type cells were almost insensitive to this antibiotic whereas application of paromomycin resulted in very effective selection. Selected eyfp-expressing microcalli were grown until enough tissue was available to scale up a new transgenic SCC. These transgenic SCC lines were evaluated molecularly and phenotypically demonstrating the presence and integration of both transgenes, the absence of Agrobacterium contamination and the ability of the transformed SCC to grow in highly selective liquid medium. The methodology described here opens the possibility of improving the production of valuable metabolites. © 2016 American Institute of Chemical Engineers Biotechnol. Prog., 32:725-734, 2016.

    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.

    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.

    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.

    Full Text Available Objective – To determine the perceived monetary value of public library service to Norwegians (both library users and nonusers.Design – Four sets of 2 questions were included in a bi‐monthly omnibus telephone survey conducted by a private agency.Setting – Norway.Subjects – A representative sample of Norwegian citizens (999 respondents. The mode of selection used for the survey is described by Aabø as follows:(1 municipalities were randomly drawn from clusters based on economic and industrial structure, demographic structure and geography; (2 starting addresses in the municipalities were randomly pulled from the national telephone directory database; and (3 the individual to be interviewed as representative of the household was the person above 15 years of age with the most recent birthday. (491 Method – The contingent valuation method was used, with questions assessing both willingness to pay (WTP and willingness to accept compensation for loss of the service (WTA. Four sets of 2 valuation questions were asked via telephone. The second question was an open‐ended question with “principally the same wording” in each set (492. The first question was worded differently in each set, with two of the sets assessing WTP and two assessing WTA. The questions were framed in the context of a “pressed economic situation where the local politicians discussed reallocation of the funding of several public services, includingt he public library” (492.Main results – Three major findings were reported: 1. The average value placed on library service by the sub samples varied between 400‐2000 Norwegian Kroner(NOK per household. This can be compared to the actual amount paid for library service – 420 NOK per household. In general, the lower bound (400 NOK reflects the WTP scenario, while the upper bound (2000 NOK reflects the WTA scenario. 2. 94% of the Norwegian population perceives that they have property rights to their local library

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.

    Leaf anatomy was studied in the mosaic Ficus benjamina cv. Starlight and non-chimeric Ficus benjamina cv. Daniel. The number of chloroplasts in a white, chlorophyll-deficient tissue declines as compared to the green tissue. However, their functional activity is retained. The leaf of the mosaic F. benjamina contains two or, sometimes, three subepidermal layers. Mesophyll forms one layer in the green and white parts of leaf palisade and one white and one green layer in the transitional zone (edge). In the transitional zone, green spongy mesophyll is located between two white spongy layers and the proportion of photosynthesizing cells varies. In cv. Daniel, there are two subepidermal layers and one layer of columnar mesophyll cells. According to the morphometry data, the proportion of white zone in the leaf correlates with the leaf position in the whole shoot: the higher the branch order, the larger the proportion of white zone. The total leaf area depends also on its position in the shoot. No such correlation was found in non-chimeric F. benjamina cv. Daniel. In the mosaic chimera, the source-sink status appears to depend on the leaf position in the shoot. Experiments with individual shoots of the same order and elimination of all lateral shoots have shown that the proportion of white zone in new leaves on the shoot increases with the total area of green zone. Thus, the area of assimilating shoot surface affects the formation of leaves in the meristem. A hypothesis was put forward that the source-sink state affects the ratio of green and white parts in the leaf primordium. Products of photosynthesis (carbohydrates) are a possible metabolic signal affecting the meristem. It cannot be excluded as well that the hormonal state undergoes changes in the chimeric plant.

    Full Text Available Stilbenes are defense molecules produced by grapevine in response to stresses including various elicitors and signal molecules. Together with their prominent role in planta, stilbenes have been the center of much attention in recent decades due to their pharmaceutical properties. With the aim of setting up a cost-effective and high purity production of resveratrol derivatives, hairy root lines were established from Vitis vinifera cv Pinot Noir 40024 to study the organ-specific production of various stilbenes. Biomass increase and stilbene production by roots were monitored during flask experiments. Although there was a constitutive production of stilbenes in roots, an induction of stilbene synthesis by methyl jasmonate (MeJA after 18 days of growth led to further accumulation of ε-viniferin, δ-viniferin, resveratrol and piceid. The use of 100 µM MeJA after 18 days of culture in the presence of methyl-β-cyclodextrins (MCDs improved production levels, which reached 1034µg/g fresh weight (FW in roots and 165 mg/L in the extracellular medium, corresponding to five-and 570-foldincrease in comparison to control. Whereas a low level of stilbene excretion was measured in controls, addition of MeJA induced excretion of up to 37% of total stilbenes. The use of MCDs increased the excretion phenomenon even more, reaching up to 98%. Our results demonstrate the ability of grapevine hairy roots to produce various stilbenes. This production was significantly improved in response to elicitation by methyl jasmonate and/or MCDs. This supports the interest of using hairy roots as a potentially valuable system for producing resveratrol derivatives.

    We studied the physical and genetic organization of chromosome 6 of tomato (Solanum lycopersicum) cv. Heinz 1706 by combining bacterial artificial chromosome (BAC) sequence analysis, high-information-content fingerprinting, genetic analysis, and BAC-fluorescent in situ hybridization (FISH) mapping data. The chromosome positions of 81 anchored seed and extension BACs corresponded in most cases with the linear marker order on the high-density EXPEN 2000 linkage map. We assembled 25 BAC contigs and eight singleton BACs spanning 2.0 Mb of the short-arm euchromatin, 1.8 Mb of the pericentromeric heterochromatin and 6.9 Mb of the long-arm euchromatin. Sequence data were combined with their corresponding genetic and pachytene chromosome positions into an integrated map that covers approximately a third of the chromosome 6 euchromatin and a small part of the pericentromeric heterochromatin. We then compared physical length (Mb), genetic (cM) and chromosome distances (microm) for determining gap sizes between contigs, revealing relative hot and cold spots of recombination. Through sequence annotation we identified several clusters of functionally related genes and an uneven distribution of both gene and repeat sequences between heterochromatin and euchromatin domains. Although a greater number of the non-transposon genes were located in the euchromatin, the highly repetitive (22.4%) pericentromeric heterochromatin displayed an unexpectedly high gene content of one gene per 36.7 kb. Surprisingly, the short-arm euchromatin was relatively rich in repeats as well, with a repeat content of 13.4%, yet the ratio of Ty3/Gypsy and Ty1/Copia retrotransposable elements across the chromosome clearly distinguished euchromatin (2:3) from heterochromatin (3:2).

    Brazil is one of the largest mango producers and the third largest mango exporter worldwide. Irradiation treatment and its commercial feasibility have been studied in our country to make it possible to develop new markets and, consequently, to compete with the major exporters of mangoes, Mexico and India. This work was designed to compare irradiation treatment with the hot water dip treatment in mangoes cv. Tommy Atkins for export and to verify that the main attributes for acceptance, color and texture, as well as carbohydrate and organic acid contents, were maintained. In this study, the fruit was divided into groups: control, hot water dip-treated (46 °C for 90 min), and irradiation-treated at doses of 0.4 kGy and 1.0 kGy. The fruit was stored at low temperature (11 °C±2) for 14 days and then at room temperature (23 °C±2) until the end of the study. The results indicated that the fruit given a dose of 1.0 kGy remained in a less advanced stage of ripening (stage 3) throughout the storage period, but experienced a greater loss of texture in the beginning of the experiment. It was noted that only the control group had higher levels of citric acid and succinic acid on the last day of the experiment. There were no significant differences in the total sugar content between any treatment groups. Gamma radiation can be used as a quarantine treatment and does not interfere negatively with the quality attributes of mangoes.

    With high nutritional value in its fruits, Dangshan Su pear has been widely cultivated in China. The stone cell content in fruits is a key factor affecting fruit quality in pear, and the formation of stone cells has been associated with lignin biosynthesis. O-Methyltransferase (OMT) is a key enzyme involved in lignin metabolism within the phenylpropanoid pathway. Here, we screened 26 OMT genes from the Pyrus bretschneideri cv. Dangshan Su genome using the DNATOOLs software. To characterize the OMT gene family in pear, gene structure, chromosomal localization, and conserved motifs of PbOMTs were analyzed. PbOMTs were divided into two categories, type I (designated PbCCOMTs) and type II (designated PbCOMTs), indicating the differentiation of function during evolution. Based on the analysis of multiple sequence alignment, cis-element prediction, and phylogenetic relationships, two candidate genes, PbCCOMT1 and PbCCOMT3, were selected for the analysis of temporal and spatial gene expression in pear. The promoter regions of both PbCCOMT1 and PbCCOMT3 contain regulatory motifs for lignin synthesis. Moreover, the two genes show high similarity and close phylogenetic relationships with CCOMTs in other species. Expression analysis showed that transcript levels of two PbCCOMTs were positively associated with the contents of both stone cells and lignin during the development of pear fruit. These results suggest that PbCCOMT1 and PbCCOMT3 are closely associated with lignin biosynthesis. These findings will help clarify the function of PbOMTs in lignin metabolism and to elucidate the mechanisms underlying stone cell formation in pear.

In the first experiment, five levels of gibberellic acid (GA3 (0, 250, 500, 1000, and 1500 mg×L−1 with four levels of cold moist stratification period of seeds at 5°C (0, 5, 10 and 15 days were launched. A factorial experiment was conducted in a completely randomized design with four replications. The statistical analysis showed that concentration of 250 mg×L−1 GA3 with 10 days of cold moist chilling significantly increased the percentage of germination of normal seedlings and reduced the mean time of germination. In the second experiment, the seeds were chilled for 10 days at 5°C and half of them treated with 250 mg×L−1 GA3 for 24 hours. The seeds treated with GA3, and those non-treated were subjected to NaCl for salinity stress. The experiment was conducted using five salinity levels (0, 20, 40, 60 and 80 mM NaCl in four replications in a completely randomized design. The results showed that purple coneflower is highly sensitive to salinity in the germination stage. The results also showed that by increasing salinity levels, the percentage of germination and normal seedlings significantly decreased and the mean time to germination increased, compared to the control treatment. But the seeds treated with GA3 showed higher viability and better performance under salinity stress condition.

    Stilbenes are defense molecules produced by grapevine in response to stresses including various elicitors and signal molecules. Together with their prominent role in planta, stilbenes have been the center of much attention in recent decades due to their pharmaceutical properties. With the aim of setting up a cost-effective and high purity production of resveratrol derivatives, hairy root lines were established from Vitis vinifera cv Pinot Noir 40024 to study the organ-specific production of various stilbenes. Biomass increase and stilbene production by roots were monitored during flask experiments. Although there was a constitutive production of stilbenes in roots, an induction of stilbene synthesis by methyl jasmonate (MeJA) after 18 days of growth led to further accumulation of ε-viniferin, δ-viniferin, resveratrol and piceid. The use of 100 µM MeJA after 18 days of culture in the presence of methyl-β-cyclodextrins (MCDs) improved production levels, which reached 1034µg/g fresh weight (FW) in roots and 165 mg/L in the extracellular medium, corresponding to five-and 570-foldincrease in comparison to control. Whereas a low level of stilbene excretion was measured in controls, addition of MeJA induced excretion of up to 37% of total stilbenes. The use of MCDs increased the excretion phenomenon even more, reaching up to 98%. Our results demonstrate the ability of grapevine hairy roots to produce various stilbenes. This production was significantly improved in response to elicitation by methyl jasmonate and/or MCDs. This supports the interest of using hairy roots as a potentially valuable system for producing resveratrol derivatives.

    The Italian wheat cv. Strampelli displays high resistance to powdery mildew caused by Blumeria graminis f. sp. tritici. The objective of this study was to map quantitative trait loci (QTLs) for resistance to powdery mildew in a population of 249 F2:3 lines from Strampelli/Huixianhong. Adult plant powdery mildew tests were conducted over 2 yr in Beijing and 1 yr in Anyang and simple sequence repeat (SSR) markers were used for genotyping. QTLs Qpm.caas-3BS, Qpm.caas-5BL.1, and Qpm.caas-7DS were consistent across environments whereas, Qpm.caas-2BS.1 found in two environments, explained 0.4-1.6, 5.5-6.9, 27.1-34.5, and 1.0-3.5%of the phenotypic variation respectively. Qpm.caas-7DS corresponded to the genomic location of Pm38/Lr34/Yr18. Qpm.caas-4BL was identified in Anyang 2010 and Beijing 2011, accounting for 1.9-3.5%of phenotypic variation. Qpm.caas-2BS.1 and Qpm.caas-5BL.1 contributed by Strampelli and Qpm.caas-3BS by Huixianhong, seem to be new QTL for powdery mildew resistance. Qpm.caas-4BL, Qpm.caas-5BL.3, and Qpm.caas-7DS contributed by Strampelli appeared to be in the same genomic regions as those mapped previously for stripe rust resistance in the same population, indicating that these loci conferred resistance to both stripe rust and powdery mildew. Strampelli could be a valuable genetic resource for improving durable resistance to both powdery mildew and stripe rust in wheat.

    The impact of water deficit on stomatal conductance (g(s)), petiole hydraulic conductance (K(petiole)), and vulnerability to cavitation (PLC, percentage loss of hydraulic conductivity) in leaf petioles has been observed on field-grown vines (Vitis vinifera L. cv. Chasselas). Petioles were highly vulnerable to cavitation, with a 50% loss of hydraulic conductivity at a stem xylem water potential (Ψ(x)) of -0.95 MPa, and up to 90% loss of conductivity at a Ψ(x) of -1.5 MPa. K(petiole) described a daily cycle, decreasing during the day as water stress and evapotranspiration increased, then rising again in the early evening up to the previous morning's K(petiole) levels. In water-stressed vines, PLC increased sharply during the daytime and reached maximum values (70-90%) in the middle of the afternoon. Embolism repair occurred in petioles from the end of the day through the night. Indeed, PLC decreased in darkness in water-stressed vines. PLC variation in irrigated plants showed the same tendency, but with a smaller amplitude. The Chasselas cultivar appears to develop hydraulic segmentation, in which petiole cavitation plays an important role as a 'hydraulic fuse', thereby limiting leaf transpiration and the propagation of embolism and preserving the integrity of other organs (shoots and roots) during water stress. In the present study, progressive stomatal closure responded to a decrease in K(petiole) and an increase in cavitation events. Almost total closure of stomata (90%) was measured when PLC in petioles reached >90%.

    Sesame (Sesamum indicum L.) is an important oil crop in many tropical and sub-tropical regions of the world, yet has received little attention in applying modern biotechnology in its improvement due to regeneration and transformation difficulties. Here within, we report the successful production of transgenic fertile plants of sesame (cv Sohag 1), after screening several cultivars. Agrobacterium tumefaciens- carrying the pBI121 plasmid {neomycin phosphotransferase gene (NPTII) and a β-glucuronidase gene (GUS)} was used in all experiments. Recovery of transgenic sesame shoots was achieved using shoot induction medium (Murashige and Skoog MS basal salt mixture + Gamborg's B5 vitamins + 2.0 mg/l BA + 1.0 mg/l IAA + 5.0 mg/l AgNO3 + 30.0 g/l sucrose + 7.0 g/l agar + 200 mg/l cefotaxime and 25 mg/l kanamycin) and shoots were rooted on MS medium + B5 vitamins + 1.0 mg/l IAA + 10.0 g/l sucrose and 7.0 g/l agar. Rooted shoots were transplanted into soil and grown to maturity in greenhouse. Incorporation and expression of the GUS gene into T0 sesame plants was confirmed using polymerase chain reaction (PCR), reverse transcriptase-PCR (RT-PCR) and GUS histochemical assay. Several factors were found to be important for regeneration and transformation in sesame. The most effective were plant genotype and the addition of AgNO3 for successful recovery of sesame shoots. Co-cultivation time and optical density of the Agrobacterium were also critical for sesame transformation. This work is an attempt to open the door for further genetic improvement of sesame using important agronomic traits.

    Full Text Available ABSTRACT Although mango is one of the tropical fruits of greater interest in the world trade, literature concerning their rootstocks (characteristics and utilization is scarce. This study aimed to characterize mango plants from cv. Imbú, widely used as rootstock in the Zona da Mata region, State of Minas Gerais (MG, Brazil. Though fruits of this cultivar do not present desirable commercial characteristics, this study allowed us to characterize part of plant morphology and fill a gap in the literature, providing subsidies for future investigations. For such, 'Imbú' plants (˜ 4-years old from the collection of the Universidade Federal de Viçosa, located in Viçosa -MG were evaluated. The descriptors were: (i leaf blade division;(ii leaf composition; (iii petiole length in relation to leaf blade; (iv phyllotaxis, (v leaf position in relation to the branch insertion; (vi leaf shape; (vii leaf apex and base angles; (viii leaf margin category; (ix venation; (x leaf length and thickness; (xi leaf length/thickness ratio; (xii leaf texture; (xiii leaf fragrance; (xix leaf color. The leaves were depicted as lanceolate, with entire margins and sharp angles at the base and apex of the leaf blade. The intensity of the green color of the leaf blade was considered intermediate and the abaxial surface staining showed less intense than that observed in the upper side. The fruits were processed and separated into peel, pulp and seeds in order to evaluate the flesh color, fresh weight and percentage of seeds, peel and pulp. It was determined the soluble solids content, starch concentration, the peel and the pulp color, the cerosity, the percentage evaluation of peel, pulp and seed and the pulp firmness. The average number of germinated seedlings per seed was estimated for 230 sown seeds.

    Full Text Available Growing plants in substrates is an alternative for the production of roses under unfavorable soil conditions. The objective of this study was to determine the biomass distribution efficiency of rose cv. Charlotte grown in soil and substrates under greenhouse conditions until second production peak. In this trial, soil and substrates with 100% burned rice husk (100BR H; 65% burned rice husk: 35% coconut fiber (65BR H; 35% burned rice husk: 65% coconut fiber (35BR H; and 100% coconut fiber (100CF were used. The experimental design consisted of a randomized complete block design with three repetitions. Destructive sampling was carried out using whole plants and flowering stems at previously determined bud stages. Leaf area and dry matter in organs were measured and growth rate and physiological indexes were calculated. The assessed variables were fitted to logistic and exponential models. The plants grown in substrates with BR H (burned rice husk showed similar values regarding dry matter and fresh weight accumulation in organs. Plants in the soil treatment were the last ones to reach the different development stages of the flowering buds, while those that were grown in 100CF were the first ones. The treatments 35BR H and 100CF showed less growth of flowering stems, which was expressed in terms of relative dry matter increase per day. The plants grown in soil showed more dry matter in leaves and stems but less in flower buds. The 65BR H treatment showed some of the highest dry matter accumulations in leaves, stems and flower buds and also showed the highest leaf area ratio, leaf weight ratio, and specific leaf area values

    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 569738 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. (3 data files).

    Context: Although epidemiological studies have found that GH and IGF-1 normalization reduce the excess mortality of active acromegaly to expected rates, cross-sectional data report some cardiovascular (CV) risk markers to be less favorable in remission than active acromegaly. Objective: The objective of the study was to test the hypothesis that remission of acromegaly after surgical therapy increases weight and adiposity and some CV risk markers and these changes are paralleled by a rise in ghrelin. Design: Forty-two adults with untreated, active acromegaly were studied prospectively. Changes in outcome measures from before to after surgery were assessed in 26 subjects achieving remission (normal IGF-1) and 16 with persistent active acromegaly (elevated IGF-1) after surgery. Setting: The study was conducted at tertiary referral centers for pituitary tumors. Main Outcome Measures: Endocrine, metabolic, and CV risk parameters, anthropometrics, and body composition by dual-energy X-ray absorptiometry were measured. Results: Remission increased total ghrelin, body weight, waist circumference, C-reactive protein, homocysteine, high-density lipoprotein, and leptin and reduced systolic blood pressure, homeostasis model assessment score, triglycerides, and lipoprotein (a) by 6 months and for 32 ± 4 months after surgery. The ghrelin rise correlated with the fall in the levels of GH, IGF-1, and insulin and insulin resistance. Weight, waist circumference, and ghrelin did not increase significantly in the persistent active acromegaly group. Total body fat, trunk fat, and perentage total body fat increased by 1 year after surgery in 15 remission subjects: the increase in body fat correlated with the rise in total ghrelin. Conclusions: Although most markers of CV risk improve with acromegaly remission after surgery, some markers and adiposity increase and are paralleled by a rise in total ghrelin, suggesting that these changes may be related. Understanding the mechanisms and

    Capacitance-Voltage (C-V) & Ballistic Current- Voltage (I-V) characteristics of Double Gate (DG) Silicon-on- Insulator (SOI) Flexible FETs having sub 35nm dimensions are obtained by self-consistent method using coupled Schrodinger- Poisson solver taking into account the quantum mechanical effects. Although, ATLAS simulations to determine current and other short channel effects in this device have been demonstrated in recent literature, C-V & Ballistic I-V characterizations by using self-consistent method are yet to be reported. C-V characteristic of this device is investigated here with the variation of bottom gate voltage. The depletion to accumulation transition point (i.e. Threshold voltage) of the C-V curve should shift in the positive direction when the bottom gate is negatively biased and our simulation results validate this phenomenon. Ballistic performance of this device has also been studied with the variation of top gate voltage.

    Coxsackieviruses B (CV-B) (Picornaviridae) are a common infectious cause of acute myocarditis in children and young adults, a disease, which is a precursor to 10-20% of chronic myocarditis and dilated cardiomyopathy (DCM) cases. The mechanisms involved in the disease progression from acute to chronic myocarditis phase and toward the DCM clinical stage are not fully understood but are influenced by both viral and host factors. Subgenomic replicons of CV-B can be used to assess viral replication mechanisms in human cardiac cells and evaluate the effects of potential antiviral drugs on viral replication activities. Our objectives were to generate a reporter replicon from a cardiotropic prototype CV-B3/28 strain and to characterize its replication properties into human cardiac primary cells. To obtain this replicon, a cDNA plasmid containing the full CV-B3/28 genome flanked by a hammerhead ribozyme sequence and an MluI restriction site was generated and used as a platform for the insertion of sequences encoding emerald green fluorescent protein (EmGFP) in place of those encoding VP3. In vitro transcribed RNA from this plasmid was transfected into HeLa cells and human primary cardiac cells and was able to produce EmGFP and VP1-containing polypeptides. Moreover, non-structural protein biological activity was assessed by the specific cleavage of eIF4G1 by viral 2A(pro). Viral RNA replication was indirectly demonstrated by inhibition assays, fluoxetine was added to cell culture and prevented the EmGFP synthesis. Our results indicated that the EmGFP CV-B3 replicon was able to replicate and translate as well as the CV-B3/28 prototype strain. Our EmGFP CV-B3 replicon will be a valuable tool to readily investigate CV-B3 replication activities in human target cell models.

    Full Text Available Abstract Background Switchgrass is one of the most promising bioenergy crop candidates for the US. It gives relatively high biomass yield and can grow on marginal lands. However, its yields vary from year to year and from location to location. Thus it is imperative to develop a low input and sustainable switchgrass feedstock production system. One of the most feasible ways to increase biomass yields is to harness benefits of microbial endophytes. Results We demonstrate that one of the most studied plant growth promoting bacterial endophytes, Burkholderia phytofirmans strain PsJN, is able to colonize and significantly promote growth of switchgrass cv. Alamo under in vitro, growth chamber, and greenhouse conditions. In several in vitro experiments, the average fresh weight of PsJN-inoculated plants was approximately 50% higher than non-inoculated plants. When one-month-old seedlings were grown in a growth chamber for 30 days, the PsJN-inoculated Alamo plants had significantly higher shoot and root biomass compared to controls. Biomass yield (dry weight averaged from five experiments was 54.1% higher in the inoculated treatment compared to non-inoculated control. Similar results were obtained in greenhouse experiments with transplants grown in 4-gallon pots for two months. The inoculated plants exhibited more early tillers and persistent growth vigor with 48.6% higher biomass than controls. We also found that PsJN could significantly promote growth of switchgrass cv. Alamo under sub-optimal conditions. However, PsJN-mediated growth promotion in switchgrass is genotype specific. Conclusions Our results show B. phytofirmans strain PsJN significantly promotes growth of switchgrass cv. Alamo under different conditions, especially in the early growth stages leading to enhanced production of tillers. This phenomenon may benefit switchgrass establishment in the first year. Moreover, PsJN significantly stimulated growth of switchgrass cv. Alamo under sub

    Chromium (Cr) at graded levels when added in sand culture of wheat (T. aestivum L. cv. UP2003) under glasshouse conditions resulted in reduction in biomass, chlorophyll and activities of catalase and peroxidase while enhanced acid phosphatase and ribonuclease activities. Elevated levels of Cr supply significantly reduced the concentration of inorganic phosphorus. With an increase in Cr supply the uptake of chromium also increased significantly in different plant parts especially in roots. Above metabolic lesions due to Cr in wheat provided evidence that the element in nutrient medium if present in excess may be inhibitory to plant growth and development.

    To observe different brain effects of electroacupuncture (EA) stimulation of Guanyuan (CV 4) and Zusanli (ST 36) in the normal subjects by using functional magnetic resonance image (fMRI). Twenty-one healthy volunteers were recruited in the present study. fMRI was used to investigate brain responses [blood-oxygenation-level-dependent (BOLD) signals] to EA stimulation of CV 4 and ST 36. A filiform silver needle was inserted into CV 4 or the left ST 36 randomly in two consecutive fMRI tests, and then manipulated with uniform reducing-reinforcing methods to induce "Deqi". fMRI scan was performed before needling, during needle retention, during EA stimulation, and post-EA. Volunteer's subjective needling sensations were recorded after EA. Data of fMRI were analyzed by using software SPM 2 and fMRI was mapped by Degree Centrality Measure method for whole brain correlation. The activation, deactivation, short-distance and long-distance functional connectivity maps of cerebral regions were investigated. The fullness and numbness feelings of the subjects were stronger during EA at ST 36 than at CV 4. EA at ST 36 or CV 4 induced apparent similar deactivation effects in the anterior cingulate and medial prefrontal cortices. The default mode of the brain at rest state was modified by needle retention and EA stimulation, respectively. The functional brain network was significantly changed after EA. The instant post-acupuncture effects (enhancement of the shortdistance functional connectivity) were mainly found in the ventral medial prefrontal cortex (VMPF) and ventral anterior cingulate cortex (vACC) in the limbic-paralimbic-neocortical network, and there were a little bit stronger signals in ST 36 than in CV 4. CONCLUSION" EA stimulation of CV 4 and ST 36 induces a similar modulation effect in the limbic-medial prefrontal network in healthy subjects.

Observation was performed on number of leaves and branches on M1V0 generation, while plantlets height and number of branches were observed a M1V1 generation. Number of survival plantlets and multiplication rate on three subsequent subcultures were observed as well. Results showed that gamma rays with dose of 20 Gy inhibited growth of leaves as much as 50% compared to control (shoots without irradiation, and branches 73.7% in three weeks. Observation on multiplication rate at M1V1 generation showed that gamma irradiation with dose of 10 Gy promoted multiplication rate as much as 10% higher than control. It can be concluded that in vitro mutagenesis using gamma iradiation with dose of 10 to 15 Gy can be used for inducing genetic variability of chrysanthemum cv. Yellow Puma.

    Electrical characteristics of Co/n-Si Schottky barrier diodes are analysed by current-voltage (I- V) and capacitancevoltage (C-V) techniques at room temperature.The electronic parameters such as ideality factor,barrier height and average series resistance are determined.The barrier height 0.76 eV obtained from the C-V measurements is higher than that of the value 0.70 eV obtained from the I-V measurements.The series resistance Rs and the ideality factor n are determined from the d ln( I ) / dV plot and are found to be 193.62Ω and 1.34,respectively.The barrier height and the Rs value are calculated from the H(I) - I plot and are found to be 0.71 eV and 205.95Ω.Furthermore,the energy distribution of the interface state density is determined from the forward bias I-V characteristics by taking into account the bias dependence of the effective barrier height.The interface state density Nss ranges from 6.484×1011 cm-2eV-1 in (Ec-0.446) eV to 2.801×1010 cm-2eV-1 in (Ec-0.631) eV,of the Co/n-Si Schottky barrier diode.The results show the presence of a thin interracial layer between the metal and the semiconductor.

  20. Analysis of β-globin chromatin micro-environment using a novel 3C variant, 4Cv.

    Full Text Available Higher order chromatin folding is critical to a number of developmental processes, including the regulation of gene expression. Recently developed biochemical techniques such as RNA TRAP and chromosome conformation capture (3C have provided us with the tools to probe chromosomal structures. These techniques have been applied to the β-globin locus, revealing a complex pattern of interactions with regions along the chromosome that the gene resides on. However, biochemical and microscopy data on the nature of β-globin interactions with other chromosomes is contradictory. Therefore we developed a novel 4C variant, Complete-genome 3C by vectorette amplification (4Cv, which allows an unbiased and quantitative method to examine chromosomal structure. We have used 4Cv to study the microenvironment of the β-globin locus in mice and show that a significant proportion of the interactions of β-globin are inter-chromosomal. Furthermore, our data show that in the liver, where the gene is active, β-globin is more likely to interact with other chromosomes, compared to the brain where the gene is silent and is more likely to interact with other regions along the same chromosome. Our data suggest that transcriptional activation of the β-globin locus leads to a change in nuclear position relative to the chromosome territory.

    Genetic transformation experiments of the different explants from Citrus grandis cv. Changshou Shatian You infected with Agrobacterium rhizogenes were carried out in darkness or in light. The optimizing culture system of Ri T-DNA transformed roots for C. grandis cv. Changshou Shatian You was constructed as follows: After the ventral wounded striations on the single activation cotyledon were inoculated by A. rhizogenes A4 (logarithmic period), they were cocultured at (25 ± 2)℃ in darkness for 25-30 days; some transformed roots were generated from wounded striations of most cotyledons. The genetically transformed ratio is (83 ± 11)%. Axenic Ri T-DNA transformed roots (hairy roots) were harvested after five subcultures. Explants were activated on MT medium. The MS medium was used for subculture of transformed roots. Mass Ri T-DNA transformed roots in which the hormone was produced independently were harvested from this optimizing culture system. White, fresh Ri T-DNA transformed roots were (1.14 ± 0.07) cm long, (0.73 ± 0.04) mm wide, and the growth direction of transformed roots was negative geotropism.

    Plant mitochondrial genomes, encoding necessary proteins involved in the system of energy production, play an important role in the development and reproduction of the plant. They occupy a specific evolutionary pattern relative to their nuclear counterparts. Here, we determined the winter wheat (Triticum aestivum cv. Chinese Yumai) mitochondrial genome in a length of 452 and 526 bp by shotgun sequencing its BAC library. It contains 202 genes, including 35 known protein-coding genes, three rRNA and 17 tRNA genes, as well as 149 open reading frames (ORFs; greater than 300 bp in length). The sequence is almost identical to the previously reported sequence of the spring wheat (T. aestivum cv. Chinese Spring); we only identified seven SNPs (three transitions and four transversions) and 10 indels (insertions and deletions) between the two independently acquired sequences, and all variations were found in non-coding regions. This result confirmed the accuracy of the previously reported mitochondrial sequence of the Chinese Spring wheat. The nucleotide frequency and codon usage of wheat are common among the lineage of higher plant with a high AT-content of 58%. Molecular evolutionary analysis demonstrated that plant mitochondrial genomes evolved at different rates, which may correlate with substantial variations in metabolic rate and generation time among plant lineages. In addition, through the estimation of the ratio of non-synonymous to synonymous substitution rates between orthologous mitochondrion-encoded genes of higher plants, we found an accelerated evolutionary rate that seems to be the result of relaxed selection.

    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)

    The identification of moving objects is a fundamental step in computer vision processing chains. The development of low cost and lightweight smart cameras steadily increases the request of efficient and high performance circuits able to process high definition video in real time. The paper proposes two processor cores aimed to perform the real time background identification on High Definition (HD, 1920 1080 pixel) video streams. The implemented algorithm is the OpenCV version of the Gaussian Mixture Model (GMM), an high performance probabilistic algorithm for the segmentation of the background that is however computationally intensive and impossible to implement on general purpose CPU with the constraint of real time processing. In the proposed paper, the equations of the OpenCV GMM algorithm are optimized in such a way that a lightweight and low power implementation of the algorithm is obtained. The reported performances are also the result of the use of state of the art truncated binary multipliers and ROM compression techniques for the implementation of the non-linear functions. The first circuit has commercial FPGA devices as a target and provides speed and logic resource occupation that overcome previously proposed implementations. The second circuit is oriented to an ASIC (UMC-90nm) standard cell implementation. Both implementations are able to process more than 60 frames per second in 1080p format, a frame rate compatible with HD television.

    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. Luz branca e vermelho-extremo são filtradas pelo grafite aumentando parcialmente a tolerância ao estresse hídrico de -0,77MPa em sementes peletizadas. Embora a luz vermelha também iniba a germinação em condições de estresse a peletização não teve efeito. Nós propomos a peletização de sementes de Raphanus saivus L. cv. redondo gigante como uma prática antes do plantio para aumentar a tolerância ao estresse hídrico.

    Full Text Available One of the effective environmental factors on plant growth is proper lighting condition during its growth period. Planting bedding varieties of dwarf Lisianthus is developing due to its various colors and long flowering-period. This study was conducted to investigate the effect of shade and different polyethylene covers on quantitative and qualitative characteristics of dwarf Lisianthus (Eustoma grandiflorum cv. Matador, as a template plant which spends its primary growth stage under greenhouse conditions. Treatments included polyethylene plastic with different percents of UV-stabilizer additive (0, 3, 5 and 8%, 50% shading cover, and open space (control. Results showed that the highest number of flowering stems, open flowers and flowering stem diameter were observed by 8% UV- stabilizer (20% shade, and had significant difference with 50% shade treatment. Maximum photosynthesis rate was obtained in control and was decreased with reduction of light intensity. To sum up, the results suggest that since no significant difference was observed in flowering characteristics between various coverings with UV-stabilizer ability and control, thus, growing dwarf Lisianthus cv. Matador could be recommended in open spaces.

    Bulk isotopic and elemental compositions of CV and CK chondrites have led to the suggestion that both originate from the same asteroid. It has been argued that magnetite compositions also support this model; however, magnetite has been studied almost exclusively in the equilibrated (type 4-6) CKs. Magnetite in seven unequilibrated CKs analyzed here is enriched in MgO, TiO2, and Al2O3 relative to the equilibrated CKs, suggesting that magnetite compositions are affected by metamorphism. Magnetite in CKs is compositionally distinct from CVs, particularly in abundances of Cr2O3, NiO, and TiO2. Although there are minor similarities between CV and equilibrated CK chondrite magnetite, this is contrary to what we would expect if the CVs and CKs represent a single metamorphic sequence. CV magnetite should resemble CK3 magnetite, as both were metamorphosed to type 3 conditions. Oxygen fugacities and temperatures of CVox and CK chondrites are also difficult to reconcile using existing CV-CK parent body models. Mineral chemistries, which eliminate issues of bulk sample heterogeneity, provide a reliable alternative to techniques that involve a small amount of sample material. CV and CK chondrite magnetite has distinct compositional differences that cannot be explained by metamorphism.

    Chondritic planetesimals are among the first planetary bodies that accreted inside and outside water snow line in the protoplanetary disk. CV3 carbonaceous chondrite parent body accreted relatively small amount of water ice, probably near the snow line, and experienced water-assisted metasomatic alteration that resulted in formation of diverse secondary minerals, including fayalite (Fa80-100). Chemical compositions of the CV3 fayalite and its Mn-Cr isotope systematics indicate that it formed at different temperature (10-300 °C) and fluid pressure (3-300 bars) but within a relatively short period of time. Thermal modeling of the CV3 parent body suggests that it accreted ∼3.2-3.3 Ma after CV3 CAIs formation and had a radius of >110-150 km. The inferred formation age of the CV3 parent body is similar to that of the CM2 chondrite parent body that probably accreted beyond the snow line, but appears to have postdated accretion of the CO and ordinary chondrite parent bodies that most likely formed inside the snow line. The inferred differences in the accretion ages of chondrite parent bodies that formed inside and outside snow line are consistent with planetesimal formation by gravitational/streaming instability.

    Full Text Available The avocado tree (Persea americana Mill. is one of the species most sensitive to salinity. Since the root system of this species is particularly affected by this type of stress, it is crucial to find a rootstock that is tolerant to saline water irrigation. Plant material from the cv. Hass was grafted on five rootstocks to find possible candidates: the clonal ‘Duke 7’, ‘Nabal’, ‘Degania 117’,’Mexicola’, and ‘Zutano’ seedlings. One year-old plants were placed in 55 L pots; river sand was used as substrate, and the plants were fertilized with a modified Hoagland solution. Vegetative growth and internal nutrient content were compared with control plants with 30 mg L-1 of Cl-, and plants treated with 200 mg L-1 Cl- for 130 days using NaCl in the nutrient solution (5.64 mM. No interaction between NaCl and the rootstocks for the vegetative growth variables was detected neither in K+ internal foliar or root content nor Ca+2 root. With regard to the carbon assimilation rate, the Nabal rootstock showed the highest rates under the NaCl treatment by retaining the highest chloride concentration in the roots and greatly limiting the concentration found in the leaves of the cv. Hass cultivar. It is therefore a promising rootstock for salt tolerance.El palto (Persea americana Mill. es una de las especies más sensibles a la salinidad, debido a que su sistema radical es particularmente afectado por este estrés, es importante identificar un portainjerto tolerante al riego con agua salina.

    Full Text Available The zinc application in sorghum seeds can affect the nutrition and the initial growth of the plants. Thus, the objective of their study was to evaluate the zinc application in the form of sulphate and oxide on the nutrition and on the initial growth of the plant of sorghum cv. BRS 310. The treatments had been five rates 0; 14,3; 28,6; 57,2 and 114,4 g Zn kg-1 of seeds and two zinc sources, the sulphate (22% of Zn and the oxide (50% of Zn. The experimental units were translucent polyethylene trays a filled with 5 L of washed thick sand, with 50 seeds of sorghum cv. BRS 310. The plants were cut 25 days after the sowing, and were evaluated for dry matter of above ground parts and the roots and it was determined the content and the accumulation of Zn in the plants. The zinc application in the oxide form promoted greater increment of dry matter in sorghum plants and provided to greater efficiency of use of the micronutrient, even so, with lesser efficiency of absorption, when compared the source sulphate. The source sulphate caused reduction in the production of the mass of the dry matter of sorghum. The sources had promoted alteration in the absorption of other nutrients for the sorghum plants, being that the source sulphate developed the absorption of P, Ca, S and Mn and the source oxide bigger absorption of K, Mg, Cu and Fe.A aplicação de zinco em sementes de sorgo poderá afetar a nutrição e o crescimento inicial das plantas.

    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.

    Full Text Available Two transgenic potato clones of cv. Achat, denominated 1P and 63P were challenged with two Potato virus Y strains (PVY O and PVY N, under greenhouse conditions, to be evaluated for resistance to these strains. Optical density values of the Elisa readings of samples from the transgenic plants were compared to readings from samples of the inoculated non-transformed plants. Clone 1P was extremely resistant to both PVY strains, reflected by not being systemically infected. Clone 63P, however, presented partial resistance to both PVY strains as local or systemic infection was delayed in some days. These results confirm the previously reported extreme resistance to PVY of clone 1P.Dois clones transgênicos de batata, derivados da cv. Achat, denominados 1P e 63P foram desafiados com duas estirpes do Potato virus Y (PVY O PVY N, em condições de casa-de-vegetação, para avaliação do nível de resistência dos clones ao vírus. Os valores de densidade óptica das leituras dos testes de Elisa foram comparados a leituras dos clones não transformados e inoculados. O clone 1P apresentou extrema resistência a ambas as estirpes, não tendo sido observada infecção sistêmica nos dois ensaios. O Clone 63P apresentou resistência parcial às duas estirpes, refletida no retardo do aparecimento de infecções sistêmicas por duas semanas. Os resultados obtidos confirmam o alto nível de resistência do clone 1P, relatado anteriormente.

    The light-response curve of photosynthesis is an important tool used to study plant ecophysiology and can provide a scientific basis for the response of plant photosynthetic characteristics to environmental factors. At present, there are five common light-response models of photosynthesis. To gain deeper insight into the applicability of different light-response models of photosynthesis and the photosynthetic physiological characteristics of Populus euramericana cv. 'Zhonglin46', two typical light-response curves of photosynthesis in P. euramericana cv. 'Zhonglin46' leaves, one under drought stress and the other under control conditions, were measured using a CIRAS-2 portable photosynthesis system. The light-response data were divided into two groups: one set of data was used to fit light-response curves, and the other set of data was used to test them. The accuracy of the fitting and the predictions of the different models were evaluated by mean square error and mean absolute error. The results showed that the light-response curves of P. euramericana cv. 'Zhonglin46' under drought stress matched the light-saturated inhibition type and that those under the control condition matched the approaching light-saturation type. The two new models (i.e., the modified rectangular hyperbola model and modified exponential model) fit the two light-response curves and their characteristic parameters well, and the fitting results of the two models were similar. Conversely, the three traditional models (i.e., the rectangular hyperbola model, nonrectangular hyperbola model, and exponential model) did not fit the two light-response curves well; in particular, they overestimated the maximum net photosynthetic rate, underestimated the light saturation point (LSP), and did not fit the net photosynthetic rate during the light-saturated stage. The LSP calculated by the "linear method" combined with the traditional models was significantly lower than the measured values; additionally, the

    Fayalite grains in chondrules in the oxidized, aqueously altered CV3 chondrite Mokoia have large excesses of radiogenic chromium-53. These excesses indicate the in situ decay of short-lived manganese-53 (half-life = 3.7 million years) and define an initial 53Mn/55Mn ratio of 2.32 (+/-0.18) x 10(-6). This ratio is comparable to values for carbonates in CI and CM chondrites and for several classes of differentiated meteorites. Mokoia fayalites formed 7 to 16 million years after Allende calcium-aluminum-rich inclusions, during hydrothermal activity on a geologically active asteroid after chondritic components had ceased forming in the solar nebula.

    A petrographic, geochemical, and oxygen isotopic study of the Bali CV3 carbonaceous chondrite revealed that the meteorite has undergone extensive deformation and aqueous alteration on its parent body. Deformation textures are common and include flattened chondrules, a well-developed foliation, and the presence of distinctive (100) planar defects in olivine. The occurrence of alteration products associated with the planar defects indicates that the deformation features formed prior to the episode of aqueous alteration. The secondary minerals produced during the alteration event include well-crystallized Mg-rich saponite, framboidal magnetite, and Ca-phosphates. The alteration products are not homogeneously distributed throughout the meteorite, but occur in regions adjacent to relatively unaltered material, such as veins of altered material following the foliation. The alteration assemblage formed under oxidizing conditions at relatively low temperatures (chondrites. The heavy-isotope enrichment of the altered regions in Bali suggest alteration conditions similar to those for the petrographic type-2 carbonaceous chondrites.

    Full Text Available Anti-hail nets for the production of apples has become a normally action for a new or update an old apple orchard. In 2007 and 2008, the development of quality and maturity parameters of cv. 'Gala Brookfield' and ‘Fuji Kiku 8' apples grafted on M9 were studied in the Fruit growing centre Maribor-Gačnik as a factor of being grown under a  blackhail net. The results showed that when grown under  the black hail net fruit of both cultivars reach a higher mean mass,  lower soluble solids content (0.6 to 1 ° Brix, and lower starch index, while no effect of the black hail net was detected on fruit flesh firmness and yield.

    Methyl jasmonate, jasmonic acid and chitosan were tested as elicitors on cell suspension cultures obtained from Vitis vinifera cv Italia to investigate their effect on stilbene production. Stilbene accumulation in the callus, grown under nonelicited conditions, was also investigated. Calli and cell suspensions were obtained in a B5 culture medium supplemented with 0.2 mg L(-1) NAA and 1 mg L(-1) KIN. Stilbene determination was achieved by HPLC/DAD/MS. Whereas callus biosynthesized only piceid, cell suspensions elicited with jasmonates produced several stilbenes, mainly viniferins. In suspended cells, methyl jasmonate and jasmonic acid were the most effective in stimulating stilbene biosynthesis, whereas chitosan was less effective; in fact, the amount of stilbenes obtained with this elicitor was not significantly different from that obtained for the control cells. The maximum production of total stilbenes was at day 20 of culture with 0.970 and 1.023 mg g(-1) DW for MeJA and JA, respectively.

    Full Text Available The development of somatic embryogenesis of coffee (Coffea spp. in liquid culture medium is a viable alternative for the propagation of these species. The use of liquid culture medium and temporary immersion systems could increase the germination of somatic embryos and improve the quality of plants. The objective of this work was to determine the effect of inoculation density on germination of somatic embryos of Coffea arabica L. cv. `Caturra rojo' in temporary immersion systems RITA®. It were used as inoculum densities 40, 50, 60, 70 and 80 somatic embryos per RITA®. After 90 days of culture the number of somatic embryos germinated, hyperhydricity symptoms, number of true leaves, length and root development was quantified. With inoculum density of 70 somatic embryos per RITA®, it was obtained a highest germination percentage (60% with good leaf development and length of the plants. Key words: hyperhydricity, liquid culture medium, partial germination, total germination, somatic embryogenesis

    Full Text Available Study on growth and flowering characteristic at different planting date done to gain optimum planting date of Hippeastrum hybridum hort.cv.’Red Lion’ at Bali Botanical garden nursery. In this research, three different planting dates, namely July 30, August 30, and September 30 were used. Parameter observed at this experiment was days to first leaf emergence, number of leaves, plant height, Days to flower scape emergence and number of bulblets per plants to know growing character.Number of flowers per scape, diameter of flower, and percent of flowering used to know flower character. It was observed that August planting gives the best result for number of flower per scape, plant height, number of leaves per plants and diameter of flower following by July planting. Late planting meaning September planting did not come out with satisfactory results.

    Full Text Available The aim of this study was to evaluate the effect of sucrose concentration in the culture medium on growth and on the establishment of mycorrhizas during the acclimatization of pineapple cv. Pérola. The plantlets were micropropagated in MS culture medium with 0, 10, 20 and 30 g L-1 of sucrose and then they were acclimatized during 12 weeks under greenhouse conditions, in a sandy soil - compost mixture, uninoculated or inoculated with a Rhizophagus clarus isolate. Plantlets from the culture medium with 20 g and 30 g of sucrose L-1 showed higher shoot and root biomass than those from sugar-free medium. Mycorrhizal colonization was lower in plantlets micropropagated in sucrose-free medium, but the intensity of arbuscules did not differ among treatments. In the 12-week period of acclimatization, mycorrhizal colonization had no effect on plant biomass.
