La traduzione dei racconti di Pat Mora: muoversi tra due lingue e due culture

This dissertation deals with the translations of seven books for children written by the Chicano author Pat Mora. I started to be interested in the Chicano world, a world suspended between Mexico and the United States, after reading a book by Sandra Cisneros. I decided to deepen my curiosity and for this reason, I discovered a hybrid reality full of history, culture and traditions. In this context, the language used is characterized by a continuous code switching between Spanish and English and I thought it was an interesting phenomenon from the literary and translation point of view. During my research in the Chicano culture, I ran across Pat Mora. Her books for children fascinated me because of their actual themes (the cultural diversity and the defense of identity) and their beautiful illustrations. For this reason, I chose to translate seven of her books because I believe they could be an enrichment for children literature in Italy. The work consists of five chapters. The first one deals with the identity of Chicano people, their history, their literature and their language. In the second chapter, I outline Pat Mora’s profile. I talk about her biography and I analyze her most famous works. In the third chapter, I introduce the seven books for children to be translated and I point out their plots and main themes. In the fourth chapter, I present the translation of the books. The fifth chapter is the translation comment. I deal with the linguistic analysis of the source texts and the analysis of the target texts focusing on the choices made during the translation process.

Optimization of a polyhydroxyalkanoates production process using a halotolerant mixed microbial culture

The rate at which petroleum based plastics are being produced, used and thrown away is increasing every year because of an increase in the global population. Polyhydroxyalkanoates can represent a valid alternative to petroleum based plastics. They are biodegradable polymers that can be produced by some microorganisms as intracellular reserves. The actual problem is represented by the production cost of these bioplastics, which is still not competitive if compared to the one of petroleum based plastics. Mixed microbial cultures can be fed with substrates obtained from the acidogenic fermentation of carbon rich wastes, such as cheese whey, municipal effluents and various kinds of food wastes, that have a low or sometimes even inexisting cost and in this way wastes can be valorized instead of being discharged. The process consists of three phases: acidogenic fermentation in which the substrate is obtained, culture selection in which a PHA-storing culture is selected and enriched eliminating organisms that do not show this property and accumulation, in which the culture is fed until reaching the maximum storage capacity. In this work the possibility to make the process cheaper was explored trying to couple the selection and accumulation steps and a halotolerant culture collected from seawater was used and fed with an artificially salted synthetic substrated made of an aqueous solution containing a mixture of volatile fatty acids in order to explore also if its performance can allow to use it to treat substrates derived from saline effluents, as these streams cannot be treated properly by bacterias found in activated sludge plants due to inhibition caused by high salt concentrations. Generating and selling the produced PHAs obtained from these bacterias it could be possible to lower, nullify or even overcome the costs associated to the new section of a treating plant dedicated to saline effluents.
