Introduction: The Calypso 4D Localization System gives the possibility to track the tumour during treatment, with no additional ionising radiation delivered. To monitor the patient continuously an array is positioned above the patient during the treatment. We intend to study, for various gantry angles, the attenuation effect of the array for 6- and 10 MV and flattening filter free (FFF) 6- and FFF 10 MV photon beams. Materials and methods: Measurements were performed using an ion chamber placed in a slab phantom positioned at the linac isocenter for 6 MV, 10 MV, FFF 6 MV and FFF 10 MV photon beams. Measurements were performed with and without array above the phantom for 0°, 10°, 20°, 40° and 50° beam angle for a True Beam STx linac, for 5×5 and 10×10 and 15×15 cm2 field size beams to evaluate the attenuation of the array. A VMAT treatment plan was measured using an ArcCheck with and without the array in the beam path. Results and discussion: Attenuation measured values were up to 3%. Attenuation values were between 1 and 2% with the exception of the 30°–50° gantry angles which were up to 3.3%. The ratio values calculated in the ArcCheck for relative dose and absolute dose 10 were both 1·00. Conclusion: Attenuation of the treatment beam by the Calypso array is within acceptable limits.

el libro ha sido organizado en tres partes. Una primera se ocupará de relatar las experiencias prácticas de funcionamiento del “dinero libre”, es decir, de medios de cambio alternativos o complementarios al dinero ofcial. En ella se describirán los experimentos de los años treinta como consecuencia de la Gran Depresión, incluidos algunos antecedentes), así como los de la posguerra, especialmente los iniciados durante la década pasada. En la segunda, estudiaremos las bases conceptuales y teóricas desarrolladas por economistas y otros pensadores sociales a lo largo de la historia y que generalmente han inspirado o servido de sustento para implementar los experimentos monetarios descritos a lo largo de la primera parte. La lista de autores "clásicos" sobre la materia abarca representantes de escuelas económicas tan variadas como la mercantilista (Boisguilbert), la de los socialistas utópicos (Proudhon), la de una facción de la anarquista (Gesell). la monetarista (Irving Fisher), la austríaca (Hayek) y la keynesiana (aparte del propio Keynes. Dudley Dillard): mientras que los más importantes autores contemporáneos incluyen a todo un heterogéneo "ejército de herejes" (en el sentido de Keynes) desconocidos -para los economistas ortodoxos- como Edgar Cann, Helmut Creutz, William Darity. Thomas Estermann. Paul Glover. Thomas Greco. Matina Hámmerli. Michel Herland. John Hotson. Margrit Kennedy. Bernard Litaer. Michael Linton. Wemer Onken, Edwin Riegel, Wemer Rosenberger. Klaus Schmitt. Lewis Solomon. Dieter Suhr, Robert Swann y Susan Witt. entre otros . Finalmente, analizaremos las características y las posibilidades teórico-prácticas de aplicar ese heterodoxo esquema monetario a escala nacional, tarea que hasta ahora no se ha intentado en país alguno. A lo largo de la parte tercera y final de este ensayo, indudablemente la más atractiva (pero también la más arriesgada), analizaremos las posibilidades de aplicación de estos esquemas monetarios al caso peruano a niveles subnacionales, enfatizando su viabilidad para los ámbitos locales. Luego de analizar la actual modalidad de acumulación y el sistema financiero del Perú y sus consecuencias, esbozaremos algunos lineamientos generales que podrían ser de utilidad -considerando las especificidades del espacio al que se aplicarían- para elaborar un programa general y proyectos-piloto para diversos ámbitos, los que específicamente podrían abarcar los espacios más disímiles: desde la macrourbe Lima-Metropolitana o su Cono Norte, pasando por la región Inka o la ciudad de Huancayo, hasta llegar a un pueblo como Mala o Chincheros, sólo a manera de ejemplo e ilustración por el momento.

La figura de Venus es el personaje del mundo greco-latino más nombrado en la poesía de Rafael Alberti. A la hora de analizar su presencia hemos distinguido dos planos: el referencial y el imaginativo. En el plano referencial incluimos todos aquellos datos que Alberti tomó del exterior dejándonos constancia de ellos en su poesía. En el plano imaginativo, el más fértil, distinguimos las diferentes transformaciones e interpretaciones de Venus que tienen lugar en su mente, dando como resultado un mundo de imágenes de una gran variedad y dinamismo. Las hemos denominado: imágenes de suplantación, identificación, simbolización, del artificio y lo grotesco, del desenfado y la ironía, e imágenes surrealistas

Andiamo ad inquadrare la figura femminile nell’organizzazione criminale presa in esame, ovvero la ‘Ndrangheta, mafia calabrese il cui nome deriva dal sostantivo greco andragathòs, che si traduce in forza, virilità, valore. È una mafia definita da molti come “liquida” per lo straordinario potere di penetrare in ogni ambito del sociale ed estendere i propri confini ben oltre il territorio calabro. Fondata sullo stretto ed indissolubile vincolo di sangue, la struttura interna della ‘Ndrangheta viene suddivisa in due livelli: la “Società Minore”, di cui fanno parte picciotto, camorrista e sgarrista, e la “Società Maggiore” che prevede “doti” di santista, vangelo, quartino, quintino e associazione. Più cosche, legate tra loro, danno vita al “Locale”, che costituisce l’unità fondamentale di aggregazione mafiosa su un determinato territorio, quasi sempre coincidente con un villaggio o con un rione di una città. Per la costituzione del “Locale” è necessaria la presenza di almeno 49 affiliati. Ogni locale è diretto da una terna di ‘ndranghetisti, detta copiata, quasi sempre rappresentata dal capobastone, dal contabile e dal capocrimine.

Quelques sites archéologiques comme Olympie, Stymphalos et Olynthe possèdent respectivement un répertoire faisant l’étude des armes de jet retrouvées durant une série de campagnes de fouilles archéologiques. Parmi ces indexes, figurent fréquemment des pointes de flèche, des balles de fronde et des saurotères (contrepoids de lance ou de javelot) provenant de différentes périodes historiques gréco-romaines. À travers les 20e et 21e siècle de notre ère, des spécialistes comme D. Robinson (1931), A. Snodgrass (1964), H. Baitinger (2001), C. Hagerman (2014) dédièrent une partie de leur expertise pour produire des synthèses sur ces objets jadis négligés. Ainsi, ils parvinrent à créer de grandes encyclopédies commentées composées de projectiles retrouvés en sol grec. À l’aide de ces bases de données, les archéologues militaires sont en mesure d’établir des datations et l’origine prétendue de certains types de projectiles. Jusqu’en 2015, les artéfacts militaires trouvés sur le site archéologique d’Argilos n’avaient jamais fait l’objet d’une étude de synthèse. D’abord, inspiré par de publications semblables, ces projectiles furent soumis à un inventaire sous forme de catalogue. Au total, deux types de balles de fronde en plomb, onze types de pointes de flèche et un type de saurotère furent identifiés. Finalement, ce nouveau contenu fut assujetti à des analyses comparatives avec d’autres sites archéologiques possédant des données similaires. Les conclusions découlant de ces analogies donnèrent naissance à la première typologie des armes de jet argilienne. Certes, les analyses se heurtèrent à certains obstacles, notamment à une compréhension de la quasi-inexistence d'une pointe de flèche typiquement "grecque" et à la confusion systématique quant à la distinction entre un saurotère et une pointe de javelot, voire possiblement un carreau de gastraphétès (une sorte d’arbalète imposante utilisée lors de sièges durant le 4e siècle av. J.-C.). En partie, ceci découle de l'historique d'échanges entre la Grèce et les autres peuples méditerranéens, balkaniques et orientaux. En outre, de nombreuses réformes militaires des périodes archaïque et classique provoquèrent une évolution constante sur les aspects stratégiques et les tactiques militaires. Considérant ces facteurs parmi tant d'autres et le fait qu'Argilos ait été une fondation grecque en territoire thraco-macédonien, la possibilité d'influence "étrangère" devient alors prépondérante sur la typologie des projectiles argiliens publiée dans le présent mémoire. Avec beaucoup d’espoir, nous croyons sans équivoque que ce travail de recherche contribuera grandement non seulement à l’histoire d’Argilos, mais aussi à l’étude des projectiles en Grèce du nord.

Three experiments were conducted with juveniles of the crayfish Cherax quadricarinatus to investigate the effect of intermittent feeding regimes on growth and the ability to tolerate the shortage of food. In experiment 1, stage III juveniles were assigned to one of seven intermittent feeding groups (from FS1: 1 day fed/1 day non-fed to FS7: 7 days fed/7 days non-fed) and two control groups, continuously fed (CF) and continuously starved (CS) animals; this experiment comprised a short-term intermittent feeding period until the first molt, followed by a continuous feeding period. In the experiment 2, stage III juveniles were assigned to one of three intermittent feeding groups (FS2 to FS4) and one control group (CF); it consisted of a prolonged intermittent feeding period, until the end of the experiment In the experiment 3, stage VI and VII juveniles were assigned to one of three intermittent feeding groups (FS2 to FS4) and one control (CF); it also consisted of a prolonged intermittent feeding period. The red claw crayfish juveniles were able to tolerate periods of intermittent feeding and underwent compensatory growth after continuous feed was re-established. The ability of crayfish to tolerate intermittent feeding was influenced by developmental stage and duration of the intermittent feeding period. Stage III juveniles survived, but decreased growth, when subjected to prolonged intermittent feeding. However, they showed full compensatory growth when the intermittent feeding period was short and followed by continuous feeding. on the other hand, stage VI-VII tolerated 60 days of prolonged intermittent feeding without any change in growth and survival. The hepatosomatic index (based on wet weight) values of the treatments and the control were similar, suggesting that intermittent feeding may not be considered a nutritional stress condition. The relative pleon weight (based on wet weight) values of the treatments and control were similar suggesting low use of nutrients from the muscle to increase the chance for survival. The juveniles of C quadricarinatus can tolerate relatively long periods of low food availability and this is an important adaptation for their survival in changing/unpredictable environments and an attribute favorable for the production of the species.

Thin film morphology of tris-(8-hydroxyquinolate) aluminium (III) (Alq3) and bis-(8-hydroxyquinolate) oxovanadium (IV) (VOq2) are compared. Alq3 films deposited onto mica at 300K look almost featureless, but dendrimers or randomly distributed needle-shaped crystallites appear as a consequence of crystallization in time. We show that a possible origin of this process is exposure to solvent vapors. On the other hand, VOq2 films retain their textured morphology as thickness increases because of stabilizing intermolecular interactions between vanadyl groups.

Alfonso de Cartagena (1385-1456), possibly the most representative figure of the courtly, political and cultural dimension built around Juan II, was the third son of the famous convert Pablo de Santa Maria, Burgos’ rabbi and, later on, bishop of that same town. He started his career as governor of Cartagena’s cathedral, afterwards he was named dean of Santiago and Segovia, canon of Burgos and, after his father’s death, bishop of Burgos. Alternatively, he played a vital role in Castile’s national and international politics, as an ambassador in Portugal’s court, at Basel’s council and before Poland’s and Germany’s kings. His work, written both in Latin and Romance, either as an historian, treatise writer, theologist or translator, is quite broad; his literary connections were strong either with Italian humanists or with those who were fond of the language arts from Spain. The first part of this Thesis seeks to provide a wide enough perspective of the author, for which we place the emphasis on the most distinctive aspects of his life. Therefore, we divided the introduction in three sections: a biographical overview, his work and, last, a study on the Memoriale uirtutum itself. Thus, regarding the first aspect, we focus on the course of his life (§1.1), where we can highlight his university education, which isn’t restricted to his training as a jurist, but we also observe that his mental vitality takes him to develop certain inquisitiveness for Moral Philosophy or Latin, which leads him to study Grammar and Rhetoric; this would allow the influence of studia humanitatis to emerge, although he never got to learn the Greek language, as we can deduce from the epistolary confrontation between him and Leonardo Bruni. We also focus on the significance of his Jewish past, upon the defence of the converts during the massacre experienced in the XVth century (§1.2), and on his presence at Basel’s council (§1.3). Despite the fact that his work as a diplomat begins during the missions in Portugal as an emissary of king Juan II, he will get recognition owing to his legation in Basel, not only among the European ecclesiastics, but also among the scholars from Italy; the importance of Basel’s council in Cartagena’s life goes beyond his official work there, either as defending the Castilian interests, or as an active member of the purely conciliar functions, since it also had a huge impact in his intellectual growth. During this time period, Cartagena establishes a friendship with Pizzolpaso, Bishop of Milan, writer, humanist, and friend of Leonardo Bruni. As a result of this type of relationship with men of such high cultural standard, he re-awakens the study of the Classical antiquity among his contemporaries, developing a huge interest in the Greco-Roman masterpieces, which will bring him closely to the highly-regarded Spanish humanists of the XVIth century...

Introducción: El cáncer colorrectal (CCR) se encuentra entre los 5 tipos de cáncer con mayor incidencia a nivel mundial. Alrededor del 20% de los casos son diagnosticados en estadios metastásico, donde el tratamiento inicialmente era quimioterapia con una supervivencia global a 5 años de 12 a 14 meses. Es así que se investiga el papel de la angiogénesis tumoral, orientado al desarrollo de terapias, implementando su uso en estadios avanzados. Metodología: Se realizó una búsqueda sistemática en las bases de datos Embase, PubMed, SciELO y LILIACS con términos estandarizados a través de la herramienta MeSH y DECS bajo los lineamientos establecidos en las guías de revisiones sistemáticas y meta-análisis (Manual Cochrane). Se tomaron estudios clínicos aleatorizados controlados con pacientes con CCR metastásico, que hayan recibido quimioterapia sola o combinada con terapias antiangiogénicas, publicados en inglés y español entre el 2003 y 2013. Resultados: 6 artículos cumplieron con criterios de inclusión. Estos reportaron 15.8 meses en promedio de supervivencia global en el tratamiento de quimioterapia asociada a terapias biológicas frente a 14.4 meses con solo quimioterapia. Los eventos adversos de tipo vascular aumentaron más en el grupo de antiangiogénicos, reportando muertes debidas a perforaciones intestinales. Conclusiones: Los regímenes de quimioterapia asociadas a terapias antiangiogénicas brindan una mayor supervivencia global y libre de progresión, al igual que mayor número de tasas de respuesta. Son terapias con eventos adversos importantes pero que deberá seleccionarse bien al paciente para disminuir su riesgo de eventos. Palabras claves: Cáncer colorrectal metastásico, terapia anti-angiogénica, quimioterapia en segunda línea, receptor del factor de crecimiento de endotelio vascular, supervivencia global.
