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

Oral History Interview with Victor Rodriguez, June 13-18, 2009
No full textInterview with Dr. Victor Rodriguez, educator and author of the memoir "The Bell Ringer," about his life and career. Dr. Rodriguez is a North Texas alumni, member of the UNT Athletic Hall of fame, member of the Geezles Fraternity, and pioneer Mexican American educator. Dr. Victor Rodriguez spotlights significant insights into his storied career through five eras: his early all-Hispanic elementary school training; his continued study and budding athletic prowess in the Edna, TX, school district; his Victoria Junior College athletic achievements and learning; his higher education, Geezle membership, and track accomplishments at North Texas State College; and his 37-year career as a teacher, coach, and superintendent in the San Antonio school district. Inspired by his Anglo third-grade teacher in an all-Hispanic school in Edna, TX, Rodriguez responded to his teacher's challenge to be a civic contributor by becoming a daily bell ringer at the local Catholic church (described in detail in his book, The Bell Ringer), a job requiring him to arise at 4:30 each morning and to run two miles one way amid nipping dogs to ring the bell. This discipline and activity would tap his athletic ability later as he surfaced as a distance district winner despite running barefoot, in blue jeans, and in an oversized t-shirt. From this beginning, he would emerge as a state champion and win a track scholarship to Victoria Junior College where he would win the national junior college title; that accomplishment would earn him track scholarship offers from many top-level four-year college programs of which he selected North Texas State College to continue his running and educational pursuits. While at NTSC, he joined the Geezle Fraternity and captured attributes of group cohesion, solidarity, and mutual benefit/trust. On the cinder track, his talents earned him gold medals in national events such as the Kansas and Drake Relays. After college and military service, Victor joined the San Antonio ISD to begin a 37-year career journey, first as a classroom teacher for bilingual children, then to increasing levels of responsibility as coach, teacher, principal, area coordinator, climaxing at the pinnacle of leadership as superintendent for the district. Along the way, he earned a PhD from the University of Texas-Austin and a year-long fellowship at Yale

La oralidad fingida en La profezia dell'armadillo de Zerocalcare: reflexiones en torno a la traducción de la variación lingüística
No full textThis study examines the graphic novel La profezia dell’armadillo (The Armadillo Prophecy, 2011) by Zerocalcare, an autobiographical comic -the author describes a personal journey from his early childhood years to the present day– which occupies a central position in his narrative career. This novel, moreover, provides an exceptional gateway into Zerocalcare’s storytelling and his media or transmedia ecosystem. The article is organized by first reviewing the concept of feigned orality. Thereafter, the notion of transmedia storytelling is presented and illustrates the author's biographical and creative trajectory. Based on the words of the author himself –“scrivo come parlo” (I write how I speak, 2015)– we identify the idiolect of the main characters, a mixture of standard Italian and expressions in Romanesco dialect, and analyse the Spanish translation. Finally, we draw some conclusions on the translation method used to render the Romanesco dialect, based on a comparison of some original and translated segments from the novel
Development of FeSi steel with increased Si content by Laser Powder Bed Fusion technology for ferromagnetic cores application: microstructure and properties
No full textAdditive manufacturing (AM) technology like Laser Powder Bed Fusion (LPBF) represents a valid alternative for the production of ferromagnetic cores. In this study, two grades of steel were considered, with standard (3.0 wt.%) and high (6.5 wt.%) Si content. The study is aimed at optimizing the process parameters in order to obtain components suitable for magnetic applications. Moreover, the effect of post-production annealing heat treatment on the microstructure evolution is investigated. The investigation included microstructural analysis by optical microscope (OM), Dynamic Scanning Calorimetry (DSC) analysis and electro-magnetic measurements (EM) on samples with optimized geometry. Results shows that both types of steel can be produced free from defects. Even if the magnetic behaviour of FeSi6.5 samples by AM do not fully reproduces that obtained on electrical steels manufactured by standard process, it appears quite promising. In this framework the optimization of post- production processes represents a promising challenge to meet market demands
Latin American Energy Markets: Investment Opportunities in Nonconventional Renewables
No full textLatin America is very rich from the point of view of its varied energy resources, with an abundance of hydroelectric generation and large reserves of fossil fuels. At present, although there is a general awareness of climate change issues associated with fossil fuel use, the facts show that economic needs over the short and medium terms are the engine of technology change.Fil: Vargas, Alberto.

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
El ser racializado: el concepto de raza en las experiencias autobiográficas de Richard Rodriguez y Kevin R. Johnson
No full textabstract: Race is a complex system founded on social ideologies that categorize and evaluate human beings into different groups based on their visible characteristics (e.g., skin color) that, according to this notion of race, indicate a person's personal traits (e.g., intelligence). The concept of race has been an integral part of American society since the ratification of the United States Constitution in the late 18th century. Early on, the practice of race within American society established one particular group as the norm: the White Anglo-Saxon Protestant. By the late 19th and early 20th centuries, the distinctions among racial groups essentially came down to "white" and "nonwhite." Consequently, certain social inequalities were bestowed upon those groups that did not fit the model of the dominant "white" group. Autobiographies, especially those from marginalized groups, can serve as an important source of these social disparities since the author is able to recount their own social experiences vis-à-vis racial practices within society. With this in mind, this thesis analyses the concept of race in relation to the personal experiences of two authors through their respective autobiographies: Hunger of Memory: The Education of Richard Rodriguez (1982) by Richard Rodriguez and How Did You Get to Be Mexican?: A White/Brown Man's Search for Identity (1999) by Kevin R. Johnson. The critical work of Paula M. L. Moya, Linda Martín Alcoff, Hazel Rose Markus, George M. Fredrickson, Genaro M. Padilla and others are used as the theoretical framework in the literary analysis of these authors' texts. In summary, the results of this study demonstrate the concept of race as a salient aspect in regards to the ideological formation of each respective author.Dissertation/ThesisM.A. Spanish 201
