Gloria Fuertes: sconfinare
No full textLa censura franchista, in vigore, in Spagna, a partire dagli anni Trenta, interviene su ogni manifestazione o prodotto culturale dell’epoca, con l’intento di diffondere l’ideologia promossa dal franchismo, mettendo a tacere qualunque possibile espressione di dissenso. Il presente lavoro si prefigge di analizzare la controversa figura della poetessa spagnola Gloria Fuertes, la quale, nonostante sia stata lungamente discriminata e confinata nell’ambito ristretto di una letteratura ritenuta marginale, è stata in grado di valicare i limiti imposti dal sistema egemonico e ritagliarsi uno spazio sacro di stridente resistenza antifranchista.
Dopo una breve premessa sul concetto di confine e alcuni essenziali cenni biografici, quindi, ci si focalizza prima sulle discriminazioni subite dall’autrice e, dopo, sulla sua sperimentazione di nuove forme e dispositivi narrativi che si rivelano capaci, sotto l’occhio disattento del lettore, di opporsi al discorso ufficiale promosso dal regime ribaltandone i presupposti teorici a favore di un’ideologia liberale e pacifista.During the Franco regime censorship acts on every demonstration or cultural
work to spread the ideology promoted by Francoism, silencing any possible
dissent. This work aims at analysing the controversial Spanish poet Gloria
Fuertes who succeeded in crossing the lines imposed by hegemonic system
and carved out her sacred space of anti-francoist resistance, although she had
been discriminated for so long and confined within the narrow context of literature
considered marginal. After a brief premise about border concept and
some essential biographical references, then, the attention at first focuses on
discriminations suffered by the author and secondly on her of new style and
narrative tools able to oppose to the official speech promoted by the regime
by overturning its theoretical assumptions in favour of a liberal and pacifist
ideology

Do You See What I See? A Simulation Analysis of Order Bundling within a Transparent User Network in Geographic Space
No full textThe Physical Internet (PI) concept presents a radical change with the aim to revert the unsustainable practices that are used for transporting goods. It identifies dedicated freight flows and transforms them into transparent open logistics networks which can be accessed by other users, such as shippers and carriers. In this paper, we test the universal network openness in which the users can tap into the PI network and place orders that will be assigned to the nearest available transport service and consequently delivered to the order sender. The objective of our paper is to investigate the impact of inserting extra service points into existing dedicated freight flows of a service-driven company. We simulate different transparency levels and routings to new pickup locations and evaluate the impact in terms of altered lead times, covered distances, and fill rates. The novel aspects presented herein are (1) deliveries based on decentralized location detection of the nearest order sender, (2) dynamically changing speed parameters of agents within specific geographic clusters based on their geo-locations in order to account for congestion levels, (3) more realistic routing strategies that consider the urban layout, and (4) transparent querying of nearest agents in space and time that meet specific conditions such as current ongoing processes, available capacity, and position. Finally, we identify the impact from a general/holistic perspective that emerges once extra orders are assigned to the service-driven company's fleet.Ambra, T (reprint author), Vrije Univ Brussel, Pleinlaan 2 PL 5-4-36, B-1050 Brussels, Belgium.

Graphene oxide as a cement reinforcing additive. Preliminary study
No full textLAUREA MAGISTRALELo scopo di questo lavoro di tesi `e la sintesi di grafene ossido e l’osservazione
della sua efficacia come additivo rinforzante in materiali cementizi.
Il grafene ossido `e stato sintetizzato attraverso ossidazione chimica di
grafite in polvere in presenza di acido solforico (H2SO4), nitrato di sodio
(NaNO3) e permanganato di potassio (KMnO4) seguendo la procedura
messa a punto da Hummer. Il grafene ossido (GO), cos`ı sintetizzato, `e stato
lavato diverse volte e trattato con ultrasuoni per assicurarne la completa
esfoliazione. Parte della soluzione acquosa contenente il GO `e stata essiccata
in forno per 24 ore a 70 C, ottenendo dei film di colore nero utilizzati
successivamente per la caratterizzazione del GO stesso e per la sintesi
dell’ossido di grafene chimicamente modificato con una polieterammina
(Jeffammine M600). Abbiamo sottoposto il GO a diversi trattamenti termici
per determinare la sua stabilit`a termica e quella dei gruppi funzionali
formatisi dopo l’ossidazione. Il grafene ossido chimicamente modificato `e
stato ottenuto attraverso una reazione di funzionalizzazione tra il GO e la
Jeffammine M600 in presenza di dimetil solfossido (DMSO) come solvente
e di dimetil amminopiridina (DMAP) come catalizzatore. La soluzione `e
stata mantenuta in agitazione e in atmosfera di azoto per tutto la durata
della reazione. Il prodotto ottenuto, GO-Jeffamine M600, `e stato sottoposto
ad una fase di purificazione per poi essere essiccato in forno a 70 C per
24 ore. Il GO ed il GO-Jeffammine M600 sono stati caratterizzati utilizzando
diverse tecniche:
- Spettroscopia Infrarossa e Raman: spettroscopie vibrazionali che
forniscono informazioni a livello molecolare dei gruppi funzionali
presenti;- Spettrometria ad Emissione Ottica e Analisi Elementare: utilizzata per
determinare la quantit`a relativa degli elementi presenti nei campioni;
- Diffrattometria a raggi-X: usata al fine di ottenere informazioni sulla
struttura cristallografica del materiale;
- Analisi Termogravimetriche: forniscono le variazioni delle propriet`a
fisiche e chimiche dei campioni in funzione della temperatura;
- Microscopia Elettronica a Trasmissione: permette di ottenere immagini
dei provini grazie all’interazione tra gli elettroni e il campione;
- Diffrazione Elettronica: fornisce informazioni sulla struttura cristallografica
dei materiali.
La preparazione dei campioni di malta additivata con il GO `e stata
effettuata in ambiente controllato, con umidit`a relativa e temperatura
costante (20 2 C). I provini sono stati confezionati miscelando il cemento
con sabbia, acqua, super fluidificante (PCs) e diverse quantit`a di GO per
poi essere testati in compressione, in flessione ed analizzati utilizzando:
- Microscopia Elettronica a Scansione: al fine di ottenere informazioni
sulla morfologia dei cristalli di cemento;
- Spettroscopia a Dispersione di Energia: per rilevare informazioni
sulla distribuzione degli elementi presenti nei campioni.This work aims to the synthesis of graphene oxide and to investigate its
effect on the mechanical resistance of the cement base composites.
Starting from graphite powder we performed a chemical oxidation using
sulfuric acid (H2SO4), sodium nitrate (NaNO3) and potassium permanganate
(KMnO4) following the Hummer’s method. The graphene oxide
sludge has been washed several times and then sonicated to ensure the
complete exfoliation of the platelets. The GO has been dried in the oven for
24 hours at 70 C obtaining black films used for the characterization and
for the synthesis of the chemically modified graphene oxide with Jeffamine
M600. The GO has been also subjected to different thermal treatment to
observe its thermal stability with increasing temperature. The functionalization
of the GO with the Jeffamine M600 (polyetheramine), has been
performed using dimethyl sulfoxide (DMSO) as solvent, dimethylaminopyridine
(DMAP) as catalyst and maintaining the solution under stirring and
nitrogen. After the purification stage the GO-Jeffamine M600 has been dried
in over for 24 hours at 70 C. The GO and the GO-Jeffamine M600 samples
were characterized with several techniques:
- Infrared and Raman spectroscopy: vibrational spectroscopy that provides
information at molecular level of the functional groups that are
present in the samples;
- Inductively Coupled Plasma Optical Emission Spectrometry and Elemental
Analyses: determines the concentration of element present in
the analyzed samples;
- X-Ray Diffraction Analyses: gives information about the crystallographic
structure of the specimens;- Thermogravimetric Analyses: changes of physical and chemical properties
of the materials are measured as function of the increasing
temperature;
- Transmission Electron Microscopy: an image of the samples is formed
due to the interaction of the electrons transmitted through the specimens;
- Selected Area Electron Diffraction: provides information about the
crystallographic structure.
The preparations of the mortar composites specimens was carried out in
a controlled environment, with constant relative humidity and temperature
(20 2 C). The specimens was prepared by mixing cement, standard
sand, water, superplasticizer (PCs) and different amount of GO. The mortars
samples were tested for the compression and flexural resistance and
characterized using:
- Scanning Electron Microscopy: gives information about the morphology
of the hydrated crystals;
- Energy Dispersive Spectroscopy: provides the distribution of elements
present in the samples
