Ni una más. International cooperation against gender-based discrimination: the femicide case in Ciudad Juárez, Chihuahua, Mexico

The femicide in Ciudad Juárez is a story made of extreme violence against women for different reasons, by different actors, under different circumstances, and following different behavioural patterns. All within a gender discrimination frame based on the idea that women are inferior, interchangeable and disposable according to the patriarchal hierarchy still present in Mexico, but strongly reinforced by a sort of conspiracy of silence provoked either by the high impunity rate, the governmental incompetence to solve the crimes, or the general indifference of the population. It is the story of hundreds of kidnapped, raped, in many cases tortured, and murdered young women in the border between Mexico and the United States. The murders first came into light in 1993 and up to now young women continue to “disappear” without any hope of bringing the perpetrators to justice, stopping impunity, convicting the assassins, and bringing justice to the families of the deceased girls and women. The main questions about femicide in Ciudad Juárez seem to be: why were they brutally assassinated?, why most of the crimes have not been solved yet?, why and how is Ciudad Juárez different from other border cities with the same characteristics?, which powers are behind those crimes in a city that implies mainly women as its labor force, and which has the lowest unemployment rate in the whole country? But there are also many other questions dealing more with the context, the Juarences’ lifestyles, the eventual hidden powers behind the crimes, the possible murderers’ reasons, the response of the local civil society, or the international community actions to fight against femicide there, among many other things, that are still waiting for an answer and that this paper will ‘narrate’ in order to provide a holistic panorama for the readers. But above all there is the need to remember that every single woman or girl assassinated there had a name, an identity, a family, a story to be told time after time and as many times as necessary, in order to avoid accepting these crimes just as statistics, as cold numbers that might make us forget the human tragedy that has been flagellating the city since 1993. We must remember as well that their deaths express gender oppression, the inequality of the relations between what is male and what is female, a manifestation of domination, terror, social extermination, patriarchal hegemony, social class and impunity. The city is the perfect mirror where all the contradictions of globalization get reflected. It is there where all the globalization evils are present and survive by sucking their women’s blood. It is a city where some concepts such as gender, migration and power are closely related with a negative connotation.

Analisi della rete di trasporto di Manduria: implementazione di un modello di simulazione

Il sistema viabile rappresenta una parte fondamentale nella dinamica dei trasporti al servizio della mobilità di trasporti e merci. La mobilità, ha fatto registrare ritmi di crescita sostenuti nel corso degli anni. Le trasformazioni sociali, del mercato del lavoro, lo sviluppo produttivo e commerciale, la posizione baricentrica tra le province jonca salentina e brindisina fanno di Manduria, una realtà dove è necessario prestare attenzione al sistema dei trasporti. Tuttavia la rete statale di vecchio stampo che risulta utilizzata, soprattutto da quote di mobilità interprovinciale per questioni di economicità del percorso e dal momento che manca una rete viaria ordinaria funzionale e scorrevole che colleghi in modo capillare il territorio fanno si che la Strada Statale 7ter risulti congestionata in maniera diffusa. La Superstrada di nuova costruzione sarebbe potuta essere un importante arteria stradale allacciandosi alla SS Taranto Brindisi Lecce collegando il sud della provincia Jonica in modo capillare ai comuni della provincia Taranto e Lecce, la quale non è stata ultimata ed avrebbe rappresentato una valida alternativa alla statale esistenti. Oltre a favorire i collegamenti tra il territorio jonico, brindisino e quello salentino, tale intervento sarebbe stato necessario per ridurre la componente di traffico di attraversamento di una serie di centri urbani, tra cui il Comune di Manduria. In questa tesi, sulla base dei dati raccolti dall’ultimo censimento nell’ambito provinciale e del Comune di Manduria, verrà implementato il funzionamento del Piano del Traffico stradale del Comune di Manduria e verranno condotte delle simulazioni, con l’ausilio del software di pianificazione di sistemi di trasporto stradale Omnitrans, versione demo, scaricabile gratuitamente dal sito www.omnitrans-international.com. Si ricercheranno stime sul funzionamento della rete, valutando la congestione del traffico ed eventualmente in termini di aumento della sicurezza e riduzione dell’inquinamento atmosferico.

Analisi termo-strutturale dell'impianto di scarico di un motoveicolo ad elevate prestazioni

Il lavoro svolto, in collaborazione con “Ducati Motor Holding”, si propone l’analisi, mediante l’applicazione di un software FEM (HyperWorks 9.0), della struttura rappresentata dai condotti di un girotubi di scarico motociclistico. Il primo obiettivo consiste nell’ottenimento di un modello agli elementi finiti della struttura. In questo senso si è anche compiuta un’indagine sperimentale per la caratterizzazione di un componente chiave del sistema (un supporto antivibrante in gomma). Le simulazioni di calcolo strutturale vogliono coinvolgere gli effetti che i carichi termici hanno nell’alterare le proprietà meccaniche dei materiali e nell’indurre sollecitazioni derivate dalle dilatazioni termiche. Si svolgono inoltre analisi di tipo dinamico per determinare i modi di vibrare della struttura e come le frequenze naturali vengano influenzate dagli effetti termici. Sulla base di ulteriori simulazioni sulla risposta in frequenza del sistema e di un riscontro sperimentale (prova accelerometrica), si è inoltre tentata una prima validazione del modello dal punto di vista dinamico. La finalità del lavoro risiede dunque nella determinazione delle criticità strutturali che il girotubi può manifestare durante il funzionamento, ma anche nell’esplorazione e applicazione delle potenzialità del software applicato, per l’analisi degli aspetti sopra esposti.

Sviluppo di un tomografo multi-energy per lo studio pre-clinico di nuove metodiche diagnostiche finalizzate al riconoscimento precoce della patologia tumorale

A new multi-energy CT for small animals is being developed at the Physics Department of the University of Bologna, Italy. The system makes use of a set of quasi-monochromatic X-ray beams, with energy tunable in a range from 26 KeV to 72 KeV. These beams are produced by Bragg diffraction on a Highly Oriented Pyrolytic Graphite crystal. With quasi-monochromatic sources it is possible to perform multi-energy investigation in a more effective way, as compared with conventional X-ray tubes. Multi-energy techniques allow extracting physical information from the materials, such as effective atomic number, mass-thickness, density, that can be used to distinguish and quantitatively characterize the irradiated tissues. The aim of the system is the investigation and the development of new pre-clinic methods for the early detection of the tumors in small animals. An innovative technique, the Triple-Energy Radiography with Contrast Medium (TER), has been successfully implemented on our system. TER consist in combining a set of three quasi-monochromatic images of an object, in order to obtain a corresponding set of three single-tissue images, which are the mass-thickness map of three reference materials. TER can be applied to the quantitative mass-thickness-map reconstruction of a contrast medium, because it is able to remove completely the signal due to other tissues (i.e. the structural background noise). The technique is very sensitive to the contrast medium and is insensitive to the superposition of different materials. The method is a good candidate to the early detection of the tumor angiogenesis in mice. In this work we describe the tomographic system, with a particular focus on the quasi-monochromatic source. Moreover the TER method is presented with some preliminary results about small animal imaging.

Sensitivity of the Top quark mass measurement with the CMS experiment at LHC using t-tbar multijet simulated events

This thesis comes after a strong contribution on the realization of the CMS computing system, which can be seen as a relevant part of the experiment itself. A physics analysis completes the road from Monte Carlo production and analysis tools realization to the final physics study which is the actual goal of the experiment. The topic of physics work of this thesis is the study of tt events fully hadronic decay in the CMS experiment. A multi-jet trigger has been provided to fix a reasonable starting point, reducing the multi-jet sample to the nominal trigger rate. An offline selection has been provided to reduce the S/B ratio. The b-tag is applied to provide a further S/B improvement. The selection is applied to the background sample and to the samples generated at different top quark masses. The top quark mass candidate is reconstructed for all those samples using a kinematic fitter. The resulting distributions are used to build p.d.f.’s, interpolating them with a continuous arbitrary curve. These curves are used to perform the top mass measurement through a likelihood comparison

Studio e sviluppo di un motore a 2 tempi diesel veloce di nuova concezione per applicazioni automobilistiche

The Department of Mechanical and Civil Engineering (DIMeC) of the University of Modena and Reggio Emilia is developing a new type of small capacity HSDI 2-Stroke Diesel engine (called HSD2), featuring a specifically designed combustion system, aimed to reduce weight, size and manufacturing costs, and improving pollutant emissions at partial load. The present work is focused on the analysis of the combustion and the scavenging process, investigated by means of a version of the KIVA-3V code customized by the University of Chalmers and modified by DIMeC. The customization of the KIVA-3V code includes a detailed combustion chemistry approach, coupled with a comprehensive oxidation mechanism for diesel oil surrogate and the modeling of turbulence/chemistry interaction through the PaSR (Partially Stirred Reactor) model. A four stroke automobile Diesel engine featuring a very close bore size is taken as a reference, for both the numerical models calibration and for a comparison with the 2-Stroke engine. Analysis is carried out trough a comparison between HSD2 and FIAT 1300 MultiJet in several operating conditions, at full and partial load. Such a comparison clearly demonstrates the effectiveness of the two stroke concept in terms of emissions reduction and high power density. However, HSD2 is still a virtual engine, and experimental results are needed to assume the reliability of numerical results.
