Sabotajes de la cultura vasca: acerca de la nación encima del canon y hacia una nación-otra bajo tachadura

2014

Esta tesis, Sabotajes de la cultura vasca: acerca de la nación encima del canon y hacia una nación-otra bajo tachadura, pretende comprender la producción cultural vasca como agente performativo que toma parte en formaciones de posiciones de sujeto hegemónicos y subalternos. Esta tesis no está tan interesada en estudiar la identidad vasca, sino que espera comprender los múltiples procesos que toman parte en su formación y el carácter modelador que asumen. En esta tesis defiendo que Ziutateaz, Bilbao-New York-Bilbao, la poesía de Itxaro Borda y la música punk de Hertzainak hacen posible que la lectora pueda elaborar una crítica estratégica de la modernidad, de las formaciones del estado y la …

Stackelberg Equilibrium with Many Leaders and Followers. The Case of Setup Costs

2016

I provide conditions that guarantee that a Stackelberg game with a setup cost and an integer number of leaders and followers has an equilibrium in pure strategies. The main feature of the game is that when the marginal follower leaves the market the price jumps up, so that a leader’s payoff is neither continuous nor quasiconcave. To show existence I check that a leader’s value function satisfies the following single crossing condition: When the other leaders produce more the leader never accommodates entry of more followers. If demand is strictly logconcave, and if marginal costs are both non decreasing and not flatter than average costs, then a Stackelberg equilibrium exists. Besides showi…

Cation exchange-based post-processing of 68Ga-eluate: A comparison of three solvent systems for labelling of DOTATOC, NO2APBP and DATAm

2014

Interest in (68)Ga has led to a number of innovations for its provision suitable for clinical application. Several post-processing methods are available to reduce eluate volume and remove metal trace impurities. In this work three cation exchange resin based post-processing methods (acetone, ethanol and NaCl) have been compared, using three model precursors (DOTATOC, NO2AP(BP) and DATA(m)), in terms of labelling yield and reproducibility. The acetone and ethanol based methods provided greater reproducibility and yields that makes subsequent purification unnecessary.

«INTELLIGENTE, IRONICA». OLTRE IL MATRIARCATO, LA DONNA IN ALCUNE OPERE DI LEONARDO SCIASCIA

2021

Intelligente e ironica. Così appare al pittore protagonista del romanzo Todo modo la donna che lascia il marito nello spiazzale antistante L’Eremo di Zafer. Il tempo di uno sguardo, di una breve sequenza. Tuttavia il suo rilievo espressivo travalica la pagina per andare, insieme a tanti piccoli tasselli narrativi di altri racconti, a comporre un’inedita rappresentazione del personaggio femminile. E ciò assume un significato particolare se facciamo attenzione per un momento alle date, se consideriamo per esempio che l’anno di pubblicazione di Todo modo è lo stesso 1974 in cui lo scrittore rilascia la famosa intervista a Franca Leosini che tanto scandalo ha suscitato soprattutto fra le fem…

Efficient alkali iodide promoted 18F-fluoroethylations with 2-[18F]fluoroethyl tosylate and 1-bromo-2-[18F]fluoroethane

2003

Abstract Radiochemical 18 F-fluorination yields of several compounds using the secondary labelling precursors 2-[ 18 F]fluoroethyl tosylate ([ 18 F]FETos) and 1-bromo-2-[ 18 F]fluoroethane ([ 18 F]BFE) could be considerably enhanced by the addition of an alkali iodide. The radiochemical yield of [ 18 F]fluoroethyl choline for example could be doubled with [ 18 F]BFE and increased from 13% to ≈80% with [ 18 F]FETos. By addition of alkali iodide to the precursor, the 18 F-fluoroethylation yields of established radiopharmaceuticals, especially in the case of automated syntheses, could be significantly increased without major changes of the reaction conditions.

A note on rank 2 diagonals

2020

<p>We solve two questions regarding spaces with a (G<sub>δ</sub>)-diagonal of rank 2. One is a question of Basile, Bella and Ridderbos about weakly Lindelöf spaces with a G<sub>δ</sub>-diagonal of rank 2 and the other is a question of Arhangel’skii and Bella asking whether every space with a diagonal of rank 2 and cellularity continuum has cardinality at most continuum.</p>

A non-relativistic model for the $[cc][\bar{c}\bar{c}]$ tetraquark

2017

We use a non-relativistic model to study the spectroscopy of a tetraquark composed of $[cc][\bar{c}\bar{c}]$ in a diquark-antidiquark configuration. By numerically solving the Schr\"{o}dinger equation with a Cornell-inspired potential, we separate the four-body problem into three two-body problems. Spin-dependent terms (spin-spin, spin-orbit and tensor) are used to describe the splitting structure of the $c\bar{c}$ spectrum and are also extended to the interaction between diquarks. Recent experimental data on charmonium states are used to fix the parameters of the model and a satisfactory description of the spectrum is obtained. We find that the spin-dependent interaction is sizable in the …
