The Formalisation of Water Use and Conditional Ownership in Colca Valley, Peru
2019
This article discusses the production and negotiation of water ownership among peasant farmers in the Majes-Colca watershed in southern Peru, where the public water administration initiated a process of formalising user rights for potable water in 2011. While a large-scale irrigation project channels water from the headwaters to export-oriented agriculture in the desert, the supply of water is getting scarcer because of climate change. The Peruvian water resources law from 2009 acknowledges water as public property, yet emphasises its economic value and encourages private investment. The farmers in the highlands see water not only as a resource but also as a lifegiving force provided by the…
The variation of the law applicable to the family property regime in EU regulations n. 2016/1103 and 1104
2021
The essay examines the discipline of EU regulations n. 2016/1103 and 1104 concerning the identification of the law applicable to the family property regime. Specifically, the work reflects on problems arising after a change, during the relationship, of the substantial law applicable to the couple?s property regime.
Jerzego Grotowskiego podróż Do wnętrza, czyli jak w PRL-u stworzyć teatralne laboratorium (i przetrwać)
2020
The purpose of my research is to demonstrate how and why Grotowski was involved with the politics and political system in Communist Poland – not only to what extent he was compromised but to what extent he compromised the authorities. I am especially concerned with determining the levels of risk, professional and personal, to which Grotowski was exposed, and what extent the Polish Secret Police and Communist Party were involved. Many people has been writing and a lot has been written on Grotowski’s theatre in general, but not about Grotowski’s theatre as an institution. The author has discovered some rare and precious materials. These are some interesting secret police files discovered in I…
Theatre as a Communicative Strategy for Teaching English as a Foreign Language to Primary Education Undergraduates: A Pedagogical Experience
2020
espanolComo profesores de lenguas estamos constantemente tratando de establecer un ambiente apropiado para que las cuatro destrezas se desarrollen plenamente a traves de actividades o ejercicios que implican un estimulo, ya que un idioma extranjero se aprende mas facilmente cuando los elementos utilizados para ensenar son mas atractivos. El teatro puede desempenar este papel, ya que es un genero educativo que se ha explorado para la ensenanza de lenguas desde el desarrollo del Enfoque Comunicativo. El proposito de este articulo, por tanto, es en primer lugar, examinar la efectividad del teatro en general con referencia a los numerosos argumentos a favor de la utilizacion de esta herramienta…
Progetto di restauro, per la fruizione e la valorizzazione della chiesa di Santa Maria in Valverde
2021
The essay presents the methodological process used for the analysis of the state of conservation and of the accessibility problems present in the church of Santa Maria in Valverde in Palermo, built in the 17th century. XVII, above previous stratifications. Furthermore, the essay shows a proposal for restoration and accessibility to the same church which in the past had a churchyard that was eliminated after the mid-twentieth century to connect the street levels. The research was conducted within the Restoration and Theory and History of Restoration Laboratory and involved the students of the LM4 course in Architecture of the Palermo Department. The suggested solution was to rebuild a new ch…
Aspecte i prefixació verbal en català antic
2021
The paper examines aspectual and selectional properties of Old Catalan prefixed verbs in comparison with their non prefixed counterparts. We ground our analysis on Talmy’s (1985, 2000) notion of verb framed and satellite framed languages and on Mateu (2002, 2003) and Mateu & Rigau (2002) theory of lexical structure, and we argue that telicity and other aspectual properties associated with prefixed verbs are by effects derived from the semantic value of the prefix together with the lexical structure they give rise to. Taking as a case in point the a- prefix of verbs such as «acórrer», we analyse the prefix as a path which relates a figure (the grammatical subject) to a ground (the argument i…
Formation of Si/SiO2 Luminescent Quantum Dots From Mesoporous Silicon by Sodium Tetraborate/Citric Acid Oxidation Treatment
2019
We propose a rapid, one-pot method to generate photoluminescent (PL) mesoporous silicon nanoparticles (PSiNPs). Typically, mesoporous silicon (meso-PSi) films, obtained by electrochemical etching of monocrystalline silicon substrates, do not display strong PL because the silicon nanocrystals (nc-Si) in the skeleton are generally too large to display quantum confinement effects. Here we describe an improved approach to form photoluminescent PSiNPs from meso-PSi by partial oxidation in aqueous sodium borate (borax) solutions. The borax solution acts to simultaneously oxidize the nc-Si surface and to partially dissolve the oxide product. This results in reduction of the size of the nc-Si core …
Pressure-Dependent Tuning of Photoluminescence and Size Distribution of Carbon Nanodots for Theranostic Anticancer Applications
2020
Carbon nanodots (CDs) have recently attracted attention in the field of nanomedicine because of the biocompatibility, cost-effective nature, high specific surface, good near infrared (NIR) photothermal conversion into heat and tunable fluorescence properties, which have paved the way toward incorporating use of CDs into innovative anticancer theranostic platforms. However, a reliable synthesis of CDs with established and controlled physiochemical proprieties is precluded owing to the lack of full manipulation of thermodynamic parameters during the synthesis, thus limiting their use in real world medical applications. Herein, we developed a robust solvothermal protocol which allow fine contr…
The Beginning and Development of the Theranostic Approach in Nuclear Medicine, as Exemplified by the Radionuclide Pair
2017
In the context of radiopharmacy and molecular imaging, the concept of theranostics entails a therapy-accompanying diagnosis with the aim of a patient-specific treatment. Using the adequate diagnostic radiopharmaceutical, the disease and the state of the disease are verified for an individual patient. The other way around, it verifies that the radiopharmaceutical in hand represents a target-specific and selective molecule: the “best one” for that individual patient. Transforming diagnostic imaging into quantitative dosimetric information, the optimum radioactivity (expressed in maximum radiation dose to the target tissue and tolerable dose to healthy organs) of the adequate radiotherapeutica…
On the Choice of the Extracellular Vesicles for Therapeutic Purposes
2019
Extracellular vesicles (EVs) are lipid membrane vesicles released by all human cells and are widely recognized to be involved in many cellular processes, both in physiological and pathological conditions. They are mediators of cell-cell communication, at both paracrine and systemic levels, and therefore they are active players in cell differentiation, tissue homeostasis, and organ remodeling. Due to their ability to serve as a cargo for proteins, lipids, and nucleic acids, which often reflects the cellular source, they should be considered the future of the natural nanodelivery of bio-compounds. To date, natural nanovesicles, such as exosomes, have been shown to represent a source of diseas…
