Cryptodacus bernardoi is known only from Colombia in Cundinamarca department in the municipios of Anolaima and Guaduas at middle altitudes on the west side of the eastern cordillera. Host plant. Three of the paratypes were reared from tiny fruits of Phoradendron sp. near piperoides (Kunth) Trel. (Figs. 43, 44), which was found parasitizing the upper part of a Psidium guajava L. shrub. This host plant is locally known by the common names “muérdago”, “matapalo”, “injerto” and “pajarito”. Phoradendron is variously classified in the Santalaceae or Viscaceae. The only previous host data for Cryptodacus was the single record of C. silvai Lima from fruit of “herva de passarinho” (Loranthus sp.) from southern Brazil (Lima 1947). The Loranthaceae, Santalaceae (and Viscaceae, when recognized as distinct from Santalaceae) belong to the order Santalales, many of which are parasitic plants. Etymology. This species is named for José Bernardo Rodríguez, father of the senior author. Comments. This species runs with difficulty in the keys of Norrbom (1994) and Norrbom & Korytkowski (2008). C. bernardoi may be most closely related to C. lopezi Norrbom, which has a similar aculeus, or it may belong to a clade along with that species and C. tau and trinotatus. The abdominal pattern is intermediate between those species, which have a distinct medial brown vitta or pair of vittae bordered by white or yellow sublateral areas on at least tergite 5 and female tergite 6, and the predominantly brown pattern in other species. In C. bernardoi the bands on tergites 4–5 in the male and 5–6 in the female may be interrupted. These four species also have the head mostly or entirely yellow posteriorly. The males were described only for C. bernardoi, C. obliquus, C. parkeri and C. tau.Published as part of Rodriguez, Pedro Alexander, Rodriguez, Erick J., Norrbom, Allen L. & Arévalo, Emilio, 2016, A new species and new records of Cryptodacus (Diptera: Tephritidae) from Colombia, Bolivia and Peru, pp. 276-290 in Zootaxa 4111 (3) on pages 277-279, DOI: 10.11646/zootaxa.4111.3.5, http://zenodo.org/record/26487
Wet Carbonation of Industrial Recycled Concrete Fines: Experimental Study and Reaction Kinetic Modeling
No full textCarbon dioxide mineralization via wet carbonation of industrial Recycled Concrete Fines (RCFs) offers a promising pathway for mitigating emissions in the cement industry, necessitating reliable kinetic models for technology scale-up. This work proposes a validated diffusion-based Shrinking Core Model describing the wet carbonation kinetics of RCFs. The model, based on parabolic diffusion law, is rigorously selected and calibrated among mineralization models in wet systems. Experimental results demonstrate a maximum carbonation efficiency of 0.81, corresponding to 95 kg CO2 uptake per tonne of RCFs, and acceptable compressive strength development when incorporating RCFs up to 10% in blended cement. Reaction rates showed a minimal temperature impact due to the offset between the CO2 solubility and diffusion through the product layer. Compared to Recycled Cement Paste (RCP) carbonation, higher diffusion coefficients are predicted, likely caused by looser product layer. Analysis highlights the importance of particle size and the CO2 partial pressure, providing insights for efficient scale-up
Screw-system-based mobility analysis of a family of fully translational parallel manipulators
No full textThis paper investigates the mobility of a family of fully translational parallel manipulators based on screw system analysis by identifying the common constraint and redundant constraints, providing a case study of this approach. The paper presents the branch motion-screws for the 3-R P C-Y parallel manipulator, the 3-RCC-Y (or 3-R P RC-Y) parallel manipulator, and a newly proposed 3-R P C-T parallel manipulator. Then the paper determines the sets of platform constraint-screws for each of these three manipulators. The constraints exerted on the platforms of the 3-R P C architectures and the 3-RCC-Y manipulators are analyzed using the screw system approach and have been identified as couples. A similarity has been identified with the axes of couples: they are perpendicular to the R joint axes, but in the former the axes are coplanar with the base and in the latter the axes are perpendicular to the limb. The remaining couples act about the axis that is normal to the base. The motion-screw system and constraint-screw system analysis leads to the insightful understanding of the mobility of the platform that is then obtained by determining the reciprocal screws to the platform constraint screw sets, resulting in three independent instantaneous translational degrees-of-freedom. To validate the mobility analysis of the three parallel manipulators, the paper includes motion simulations which use a commercially available kinematics software. © 2013 Ernesto Rodriguez-Leal et al
Thermal and light irradiation effects on the electrocatalytic performance of hemoglobin modified Co3O4-g-C3N4 nanomaterials for the oxygen evolution reaction
No full textThe oxygen evolution reaction (OER) plays a key role in the water splitting process and a high energy conversion efficiency is essential for the definitive advance of hydrogen-based technologies. Unfortunately, the green and sustainable development of electrocatalysts for water oxidation is nowadays a real challenge. Herein, a successful mechanochemical method is proposed for the synthesis of a novel hemoglobin (Hb) modified Co3O4/g-C3N4 composite nanomaterial. The controlled incorporation of cobalt entities as well as Hb functionalization, without affecting the g-C3N4 nanoarchitecture, was evaluated using different physicochemical techniques, such as X-ray diffraction, N2-physisorption, scanning electron microscopy, UV-visible spectroscopy and X-ray photoelectron spectroscopy. The beneficial effect of the resulting ternary bioconjugate together with the influence of the temperature and light irradiation was investigated by electrochemical analysis. At 60 °C and under light exposition, this electrocatalyst requires an overpotential of 370 mV to deliver a current density of 10 mA·cm-2, showing a Tafel slope of 66 mV·dec-1 and outstanding long-term stability for 600 OER cycles. This work paves a way for the controlled fabrication of multidimensional and multifunctional bio-electrocatalysts
Caracterização dos efeitos biológicos das lectinas de Canavalia brasiliensis (ConBr) e de Canavalia ensiformes (ConA) em preparações do sistema nervoso central e em células tumorais
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciencias Biológicas. Programa de Pós-Graduação em Neurociências.Lectinas são proteínas com especificidade de ligação à resíduos de carboidratos. ConBr e ConA são lectinas com especificidade para D-glicose/D-manose, extraídas de plantas, família Leguminosae, tribo Phaseolae, subtribo Diocleinae. Estas lectinas podem estimular a proliferação de linfócitos e produção de interferon , ativar macrófagos e produzir inflamação, além de induzirem apoptose em vários tipos celulares. Apesar destes efeitos, existem poucos estudos das ações destas lectinas sobre células tumorais e sobre preparações neurais, especialmente sobre os mecanismos de sinalização celular envolvidos na regulação da neurotransmisssão, diferenciação, proliferação e morte celular. O presente trabalho tem como objetivos: a) determinar as possíveis ações de ConBr e ConA sobre a viabilidade e modulação da liberação do neurotransmissor glutamato no terminal sináptico (sinaptossoma); b) determinar possíveis ações destas lectinas sobre a viabilidade celular em fatias hipocampais, em células de linhagens tumorais de glioma C6 e mieloleucêmicas U-937; c) determinar ações dessas lectinas sobre a via de sinalização de proteínas quinases ativadas por mitógenos (MAPKs) nestas preparações. ConBr e ConA (5-100 g/ml) foram incubadas (1-5min) com sinaptossomas ou fatias hipocampais obtidas de ratas adultas (60-70dias). Além disso, estas lectinas (0,5-100 g/ml) foram incubadas por 24-48h com linhagens tumorais de glioma C6 ou mieloleucêmicas U-937. Os testes de viabilidade foram realizados através de medidas da liberação de LDH ou da redução do MTT. A liberação de 3H-glutamato foi medida através de cintilação líquida. A modulação das vias de MAPKs foi avaliada através de Western blotting usando anticorpos contra as formas fosforiladas e totais de ERK1/2, JNK1/2 e p38MAPK. Os resultados mostraram que ConA e ConBr não alteraram a viabilidade e nem a liberação basal de L-[3H]glutamato em sinaptossomas. -Latrotoxina 1nM sozinha aumentou 43% da liberação de L-[3H]-glutamato em relação ao controle e ConBr provocou um incremento significativo de 20% no efeito de -latrotoxina. E em sinaptossomas, a ConBr mas não ConA estimulou ERK1/2. Estas lectinas não alteraram a viabilidade celular e nem a fosforilação de MAPKs em fatias hipocampais. ConA e ConBr diminuiram fortemente a viabilidade celular em linhagens de glioma C6, sendo este efeito acompanhado de redução da fosforilação de ERK1/2. Nas células mieloleucêmicas U-937, ConBr causou uma redução de viabilidade significativa. Apesar da alta homologia estrutural entre ConA e ConBr estas lectinas apresentaram variações em alguns efeitos biológicos. Os resultados descrevem de forma inédita a modulação, por ConBr, da liberação de glutamato e de MAPKs em sinaptossomas. Adicionalmente, demonstram uma ação de ConBr e ConA na morte celular e/ou inibição de proliferação celular em linhagens tumorais. Em conjunto os dados sugerem ConBr como uma possível ferramenta para estudo da transmissão sináptica e ConBr e ConA como potenciais ferramentas para estudo de processos relacionados a morte celular em células tumorais
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
Pioneering digital culture measurement in organizations: Construct development and psychometric validation
No full text[EN] Background Digital transformation is increasingly recognized as a cultural challenge, yet there is a lack of robust theoretical frameworks and validated instruments to systematically assess digital culture within organizations.Objective This study aims to develop and validate a psychometric measurement scale for digital culture, addressing a significant gap in the literature and providing a practical tool for assessing cultural readiness for digital transformation.Methods We first establish a clear conceptual definition of the digital culture construct. Based on this definition, we design a measurement scale and test it on a representative sample of 183 firms. To assess the scale's psychometric properties, we employ confirmatory factor analysis (CFA) and partial least squares structural equation modeling (PLS-SEM).Results The results confirm the reliability and validity of the proposed digital culture scale. The instrument demonstrates strong psychometric properties and consistent measurement performance across diverse organizational contexts.Conclusions This study contributes to academic research by introducing a theoretically grounded and empirically validated scale for digital culture. It also provides a practical tool for organizations to evaluate cultural alignment with digital transformation efforts and identify areas for cultural development.Sanchis-Pedregosa, C.;Leal-Rodriguez, AL.;Orero-Blat, M.;Palacios Marqués, Daniel (2025).
