FIRST STAGES OF MICROSPORE REPROGRAMMING TO EMBRYOGENESIS THROUGH ISOLATED MICROSPORE CULTURE IN LOQUAT
2011
The current experiments were undertaken to develop a method for regenerating doubled haploid (DH) plants of Eriobotrya japonica (Thunb.), Rosaceae, subfamily Maloideae through isolated microspore culture of nine loquat cultivars. Protocols were developed for isolation and culture of loquat microspores. Isolated microspores in vitro cultured started dividing and developing multicellular, globular and irregular structures. After 4 weeks of culture, the responding microspores produced yellowish/white callus. The embryogenic response of microspores was highly dependent on the cultivar and on the medium composition.
Manuel Momparler Marco: instalaciones de la fábrica Momparler y proyectos urbanísticos
2015
"Manuel Momparler Marco: instalaciones de la fábrica Momparler y proyectos urbanísticos" recoge documentación sobre las instalaciones de la fábrica Momparler y proyectos urbanísticos -como hotel Alhambra, inmuebles en la calle periodista Azzatti y otros-, existentes en el Archivo Municipal de Valencia. Manuel Momparler (1844-1922), empresario ceramista e inventor valenciano, inició una saga familiar empresarial de varias generaciones, iniciada con su emigración a Cuba, hasta la Guerra Civil española, el exilio y la vuelta, comenzando de nuevo. Este documento recoge documentación existente en Archivo Municipal de Valencia sobre la evolución de las instalaciones de su fábrica, así como la amp…
Association between marfan syndrome and oral health status : a systematic review and meta-analysis
2019
Background: The purpose was to identify and assess the existing scientific evidence from epidemiologic, non-experimental, observational studies of associations between Marfan’s syndrome and oral diseases. Material and Methods: Electronic literature searches in MEDLINE (OVID), The Cochrane Library, Scopus and the Web of Science were conducted to identify all relevant articles. Eligibility was based on inclusion criteria, and quality assessments were conducted. The outcome variables were probing depth, gingival margin, clinical attachment level, bleeding on probing, gingival status, periodontal status, tooth mobility, furcation involvement and decayed, missing and filled teeth index. After ex…
Value creation in the international public procurement market: In search of springbok firms
2019
Abstract Public procurement accounts for more than 10% of global GDP. Digital transformation of public procurement creates new opportunities for value creation in international markets. Identifying and analyzing the companies, especially the SMEs, that can capitalize on these opportunities is therefore an important issue for policymaking, management, and scientific research. This study linked microdata on selected bidders from the Tenders Electronic Daily (TED) e-procurement portal and the Orbis database. Based on a sample of 933 Spanish companies, the analysis provides empirical support for the cross-border size bias conjecture. The reason for this bias is the predominance of large compani…
How online advertising competes with user-generated content in TripAdvisor. A neuroscientific approach
2020
Drawing on cognitive load theory, congruence research, and dual processing models, the purpose of this study is to determine the effectiveness of online advertising in social media. To this end, three separate studies were conducted. First, using eye-tracking and electroencephalography, we examine the differences, based on whether or not an ad is embedded, in subjects’ visual attention and engagement in a TripAdvisor webpage. Our findings showed that synergies between social media content and advertising content positively affect users’ visual attention. A second study, using an online survey, assessed the impact of congruent/incongruent ads on ad recall. A third study, using ey…
Product placement in video games: The effect of brand familiarity and repetition on consumers´ memory
2017
Product placement in video games is gaining momentum as a means to target audiences in an indirect and engaging way. This research uses a 2 (high repetition vs low repetition) x 2 (high brand familiarity vs low brand familiarity) factorial design to test the effects of repetition and brand familiarity on consumers’ memory for brands placed in video games. Results suggest that consumers recall better familiar than unfamiliar brands placed in the video game and repetition increases recall for familiar brands. Results also suggest an interaction effect of repetition on brand recognition for unfamiliar brands but not for familiar brands. Managerial implications, limitations, and future research…
Micro lensing induced lineshapes in a single mode cold-atom hollow-core fiber interface
2018
We report on the observation of strong transmission line shape alterations in a cold-atom-hollow-core-fiber interface. We show that this can lead to a significant overestimation of the assigned resonant optical depth for high atom densities. By modeling light beam propagation in an inhomogeneous dispersive medium, we attribute the observations to micro lensing in the atomic ensemble in combination with the mode selection of the atom-fiber interface. The approach is confirmed by studies of Rydberg electromagnetically induced transparency line shapes.
Novel plasmonic sensor design using plasmon-induced transparency
2010
We introduce a novel sensor concept in the field of plasmonics, namely plasmon-induced transparency sensors. These sensors combine localized particle plasmon resonances with extremely small sensing volume with excellent sharp spectral resonances that show a good respose to refractive index changes of the surrounding environment. The principle is based on the plasmonic analog of electromagnetically induced transparency (EIT) between a radiative dipole and a nonradiative quadrupole antenna. This effect yields a spectrally narrow resonance within a broad localized particle plasmon resonance in the near-infrared spectral region [1, 2]. Using deposition of biotin and streptavidin, we demonstrate…
Electrochemically induced free solvent transfer in thin poly(3,4-ethylenedioxythiophene) films
2015
International audience; In dynamic intrinsically conducting films, counterions transfer and conformational movements stimulated by the electrochemical reactions affect the free water molecules transfer. Poly(3,4-ethylenedioxythiophene) or PEDOT is included in this category. Here, p-doping of PEDOT immersed in LiClO4 aqueous solution was explored by ac-electrogravimetry. Electrochemical impedance spectroscopy combined with mass impedance spectroscopy proves useful for species identification and kinetics. For PEDOT, new equations have been developed to analyze the ac -electrogravimetry response. Quantitatively, faster free water transfer and slower coupled View the MathML sourceClO4−/free wat…
Control of flow separation using electromagnetic forces
2003
Introduction If a fluid is electrically conductive, its flow may be controlled using electromagnetic forces. Meanwhile, this technique is a recognized tool even on an industrial scale for handling highly conductive materials like liquid metals. However, also fluids of low electrical conductivity as considered in the present study, like sea--water and other electrolytes, permit electromagnetic flow control. Experimental results on the prevention of flow separation by means of a streamwise, wall parallel Lorentz force acting on the suction side of inclined flat plates and hydrofoils will be presented. Force Configuration The stripwise arrangement of permanent magnets and electrodes of alterna…
