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
El hombre de mi vida: análisis de la traducción de los culturemas del ámbito gastronómico
No full textEs opinión compartida que en la producción de Manuel Vázquez Montalbán (MVM) la gastronomía es un elemento narrativo importante y el conjunto de su obra lo demuestra sobradamente. El polifacético autor barcelonés (Barcelona, 1939-Bangkok, 2003) concibe la gastronomía en un sentido amplio como el “arte de preparar y apreciar una buena comida” (2002: 51), así pues no sólo la afición a comer bien, sino también la capacidad de seleccionar los mejores ingredientes, prepararlos y servirlos.
Atendiendo a las reflexiones de Newmark (2004: 137) sobre la traducción de las ‘palabras culturales’ en el ámbito de la cultura material, la comida, como subraya este autor, “es para muchos la expresión más delicada e importante de la cultura nacional”, en consecuencia, “los términos alimentarios están expuestos a la gama más variada de procedimientos de traducción”.
Nosotros, en este artículo, que se plantea como continuación ideal de uno anterior donde habíamos centrado nuestro análisis en la identificación y catalogación de las diferentes soluciones traductoras adoptadas para trasladar los culturemas del ámbito gastronómico presentes en La soledad del manager, nos proponemos, en primer lugar, al igual que en el precedente, identificar el método traductor empleado sirviéndonos, en parte, de los datos que nos proporcione el inventario recopilatorio de las técnicas de traducción utilizadas en el texto meta (TM).
En segundo lugar, mediante la comparación y evaluación de las técnicas translativas utilizadas en cada novela, trataremos de determinar si efectivamente, como es lógico pensar, se ha producido una evolución en el tiempo del método traductor adoptado.
El presupuesto del que partimos es el de que las áreas culturales no actúan como depósitos perennemente estancos. Porque es evidente que tanto el contexto de recepción de la traducción como el del texto original evolucionan, cambian. Así pues, a nuestro modo de ver, visto el éxito y el número de traducciones de este autor al italiano, consideramos que el grado de familiaridad del lector italiano con la cultura española-catalana y con la obra de Vázquez Montalbán en el año 2000, año de publicación de L’uomo della mia vita, era probablemente mayor que en 1993, año en el que ve la luz en Italia La solitudine del manager
Palabras para una pandemia. Algunas notas sobre las creaciones neológicas utilizadas para comunicar la enfermedad por coronavirus SARS-CoV-2
No full textEl 13 de marzo de 2020, ante la propagación en España del coronavirus SARS-CoV-2, el presidente del Gobierno, Pedro Sánchez, dio una rueda de prensa en la que anunciaba que al día siguiente se celebraría un Consejo de Ministros extraordinario para decretar el Estado de Alarma en todo el país durante los siguientes 15 días. Así pues, con el objetivo de frenar el aumento de contagios, la población española se confinó en su casa el domingo 15 de marzo de 2020. A decir verdad, sucesivamente el Gobierno pidió seis prórrogas, de modo que el confinamiento se ha mantenido durante 98 días, desde el 15 de marzo hasta el 21 de junio. Por fin, después de casi cien días de bloqueo y miles de fallecidos por la enfermedad denominada COVID-19, el pasado 21 de junio cuando el reloj marcó las 00.00 horas, España salió del estado de alarma para dar paso a la nueva normalidad, una denominación que se ha erigido en un sintagma clave en el discurso político, una muletilla léxica utilizada para referirse a la nueva realidad provocada por la covid-19, porque, parafraseando a Monterroso, desafortunadamente el nuevo coronavirus todavía está ahí. En este extraño periodo, a medida que el SARS-CoV-2 ha ido avanzando, algo que todos los ciudadanos hemos podido comprobar es la importancia de los medios de comunicación para acceder a información especializada e incluso para compartir opiniones. Efectivamente, la existencia de medios sólidos e independientes, capaces de investigar y criticar las acciones de la administración pública han permitido a la población informarse de manera fidedigna sobre lo que estaba y está sucediendo. En este sentido, hay que reconocer que la prensa está desarrollando un rol clave en la correcta difusión de las noticias sobre la pandemia. Por otra parte, no cabe duda de que, como sostenía María Moliner, los periódicos son el instrumento ineludible para agarrar al vuelo todas las palabras de la vida, “porque allí viene el idioma vivo, el que se está usando, las palabras que tienen que inventarse al momento por necesidad” (citado en García Márquez, 1981) . Así pues, teniendo en cuenta el servicio inestimable que la prensa ha prestado y está prestando en el contexto de esta crisis, en las líneas que siguen, utilizando como corpus de detección el diario nacional El País y sus Suplementos (del 1 de febrero al 5 de agosto de 2020, tanto en soporte impreso como digital), primero, identificaremos las palabra más utilizadas para definir y caracterizar la actual crisis sanitaria. A continuación, partiendo del principio de que toda lengua viva crea palabras nuevas para designar realidades nuevas (Guerrero Ramos 1997: 11), ilustraremos cuáles son los principales neologismos surgidos a raíz de la actual pandemia
R. Graham Cooks and Ismael Cotte-Rodriguez reviewing data
No full textR. Graham Cooks, from left, Purdue's Henry Bohn Hass Distinguished Professor of Analytical Chemistry, works with former doctoral student Ismael Cotte-Rodriguez to review data after using a new miniature mass spectrometer to detect explosives. The portable instrument weighs approximately 22 pounds, is roughly the size of a shoebox and can be installed as part of a remote sensor network to monitor the air in subways, airports or office buildings.College of Science

Design of a Marine Wireless Sensor Network for Seawater Quality Monitoring
No full textIn questa tesi viene presentata una profonda analisi di tutti i blocchi costituenti una versatile rete marina di sensori (WSN). Il framework discusso, incentrato sull’utilizzo di boe sensore per il monitoraggio in tempo reale della qualità dell’acqua marina, è stato pensato come estensione delle classiche sonde CTD, usate per la misura della conducibilità, della temperatura e della profondità dell’acqua marina. Queste vengono poi tipicamente equipaggiate con strumentazione addizionale per la misura della concentrazione di clorofilla-a e torbidità dell’acqua. Tuttavia questa strumentazione addizionale è di solito molto costosa e perciò ha di fatto impedito la realizzazione di un’ampia rete di unità di misura. A patire perciò da questa considerazione e tenendo presente le normative italiane in questo ambito, l’autore propone un nuovo ed economico modulo elettronico per il rilevamento in-vivo della clorofilla-a microalgale.
L’implementazione di tale sensore ha richiesto inoltre l’implementazione di una innovativa tecnica di progettazione di circuiti integrati, usata per derivare una completa rappresentazione simbolica del circuito e successivamente per simulare milioni di combinazioni dei parametri circuitali in un tempo esiguo. Il calcolo di una adeguata figura di merito permette quindi di selezionare la più appropriata combinazione di componenti passivi.
L’autore presenta inoltre due innovative tecniche prodotte: la prima per la caratterizzazione dei consumi energetici dei moduli di una WSN, tipicamente soggetti ad elevate variazioni dinamiche di corrente, e la seconda per una completa caratterizzazione dei moduli termoelettrici usati per fornire autonomia energetica, in cogenerazione con i pannelli solari, alle boe.A solid investigation of all the building blocks of a versatile Wireless Sensor Network for seawater monitoring applications is presented in this thesis.
The discussed framework, based on buoys for real-time monitoring of seawater, is intended to be an extension of the classical CTD probes, used for measuring the water conductivity, temperature and depth, and usually equipped with additional instrumentation for measuring the chlorophyll-a concentration and water turbidity. This additional instrumentation is usually very expensive and thus de facto has prevented the realization of a wide network of measuring unit. Starting from this assumption and in line with the Italian regulations in this area, the author proposes a new cheap module for in-vivo detection of chlorophyll-a.
The implementation the aforementioned sensor also requested the implementation of a novel circuit design technique, used to give a full symbolical representation of the circuit, which is then numerically simulated for millions of different combinations of the design parameters in a small time. The computation of a figure of merit thus leads to choose the most appropriate combination of adopted passive components.
The author also present two novel techniques: the first for power consumption characterization of WSN modules, which are usually subjected to high dynamic current variations and the second for the characterization of thermoelectric modules that are intended to be used to provide energy self-sufficiency in cogeneration with solar panel
Smoothing and local refinement techniques for improving tetrahedral mesh quality
No full textThe improvement in the mesh quality without changing its connectivity is bounded. This bound is associated with the topology of the mesh and with the constraints imposed by the boundary of the domain. To solve this problem, we propose in this work to combine the tetrahedral mesh optimisation technique introduced in [Montenegro R, Montero G, Escobar JM, Rodriguez E, Gonzalez-Yuste JM. Tetrahedral mesh generation for environmental problems over complex terrains. Lect Notes Comput Sci 2002;2329:335-44; Escobar JM, Rodriguez E, Montenegro R, Montero G, Gonzalez-Yuste JM. Simultaneous untangling and smoothing of tetrahedral meshes. Comput Methods Appl Mech Eng 2003; 192:2775-87] with the local mesh refinement algorithm presented in [Gonzalez-Yuste JM, Montenegro R, Escobar JM, Montero G, Rodriguez E. An object oriented method for tetrahedral mesh refinement. In: Proceedings of the 3rd international conference on engineering computational technology, Praga 2002; 1-18]. The main idea consists in increasing the node number, and thus, the degrees of freedom, in the neighbourhood of the regions where the elements have poor quality. Then, we refine all the elements whose quality are below to a certain threshold. Once it is done, we initiate another stage of optimisation until the quality of the mesh reaches a limit.243024230,632Q2SCI
A note on the Cahn-Hilliard equation in involving critical exponent
No full textsummary:We consider the Cahn-Hilliard equation in with two types of critically growing nonlinearities: nonlinearities satisfying a certain limit condition as and logistic type nonlinearities. In both situations we prove the -bound on the solutions and show that the individual solutions are suitably attracted by the set of equilibria. This complements the results in the literature; see J. W. Cholewa, A. Rodriguez-Bernal (2012)
Temperature and pressure dependence of the optical properties of Cr3+-doped Gd3Ga5O12 nanoparticles
No full textSince the crystal-field strength at the Cr3+ site is very close to the excited-state crossover (ESCO), this work investigates the optical properties of Cr3+-doped Gd3Ga5O12 (GGG) nanoparticles as a function of temperature and pressure in order to establish the effect of the ESCO on the optical behaviour of nanocrystalline GGG. Luminescence, time-resolved emission and lifetime measurements have been performed on GGG: 0.5% Cr3+ nanoparticles in the 25-300 K temperature range, as well as under hydrostatic pressure up to 20 GPa. We show how low temperature and high pressure progressively transforms Cr3+ T-4(2) -> (4)A(2) broadband emission into a ruby-like E-2 -> (4)A(2) luminescence. This behaviour together with the lifetime dependence on pressure and temperature are explained on the basis of the spin-orbit interaction between the T-4(2) and E-2 states of Cr3+
