The south coast of Palermo. Planning the resilient city
2017
Il contributo individua i temi progettuali per la definizione di temi di progetto sul territorio della cosiddetta "costa sud" della città di Palermo. Il contributo descrive i temi di sviluppo, analizza le risorse presenti e definisce alcuni elementi progettuali che verranno sviluppati sia all'interno della ricerca presentata nel volume, sia nelle politiche di trasformazione urbana del Comune di Palermo. The paper identifies the design themes for project in the so-called "south coast" of the city of Palermo. The contribution describes the development themes, analyzes the resources present and defines some design elements that will be developed both within the research presented in the volume…
Biological and Proteomic Characterization of the Anti-Cancer Potency of Aqueous Extracts from Cell-Free Coelomic Fluid of Arbacia lixula Sea Urchin i…
2022
Echinoderms are an acknowledged source of bioactive compounds exerting various beneficial effects on human health. Here, we examined the potential in vitro anti-hepatocarcinoma effects of aqueous extracts of the cell-free coelomic fluid obtained from the sea urchin Arbacia lixula using the HepG2 cell line as a model system. This was accomplished by employing a combination of colorimetric, microscopic and flow cytometric assays to determine cell viability, cell cycle distribution, the possible onset of apoptosis, the accumulation rate of acidic vesicular organelles, mitochondrial polarization, cell redox state and cell locomotory ability. The obtained data show that exposed HepG2 cells under…
Palermo reciclica. Scenari del riciclo per aree, infrastrutture e paesaggi a fine ciclo
2021
Il saggio affronta il tema del riciclo urbano attraverso la mappatura e l'analisi di fenomeni di dismissione e sotto-utilizzo presenti nella città di Palermo. Il tema del riciclo si offre a una città come Palermo come potenziale strumento dirompente di trasformazione. La mappatura e la definizione della tassonomia degli spazi da riconvertire per conoscere le tipologie di offerta potenziale è considerato il primo importante passo a cui affiancare la formulazione delle regole per l’accesso e la condivisione degli spazi, nonché possibili strategie e politiche pubbliche per generare nuove funzioni o consolidare e rinnovare pratiche d’uso già avviate.
Mechanical properties of recycled polyethylene ecocomposites filled with natural organic fillers
2006
The use of natural organic fillers in addition to postconsumer recycled polymers is getting a growing interest during the last years; this is due to many advantages they can provide in terms of cost, aesthetic properties, environmental impact. In this work, several types of wood flour (differing each other with regard to production source and particle size) were added to a recycled polyethylene coming from films for greenhouses and the effects of filler type, content, and size were investigated. Investigation was then focused on the improvement of mechanical properties, through the addition of polar copolymers (ethylene-co-acrylic acid, ethylene-vinyl acetate) and a maleic anhydride-grafted…
On the degree of binder activity of reclaimed asphalt and degree of blending with recycling agents
2020
It is common practice to assume full blending of the aged binder of reclaimed asphalt (RA) within the design of new asphalt mixtures. Although being practical, this assumption has often led designers to asphalt mixtures lacking binder. Hence, going towards recycled asphalt mixtures (RAM) there is a need to have a better understanding of the blending phenomena, to have a general agreement on terminology and finally adapting RA classification and mix design procedures accordingly. This manuscript aims at being both a reference and stimulus for the scientific community to work in this direction and on this basis provides a nomenclature and a theoretical framework of the blending phenomena. The…
CO-Evolution Between CCC-Driven Cash Flow Management and Transformation of R&D : Amazon’S Endeavor
2019
Amazon became the world R&D leader in 2017 by rapidly increasing R&D investment. The company’s extremely large amount of R&D funds is the result of an ample free cash flow generated by sophisticated cash conversion cycle (CCC) management. Increased R&D induced business advancement and lean cost structure construction leading to further increase in cash flow which has stimulated interaction between vendors, customers, and Amazon via the Amazon marketplace. Activated interaction accelerated CCC advancement, a subsequent free cash flow increase, and user-driven innovation, thus accelerated the transformation of routine and periodic alteration activities into significant improvement simultaneou…
Transitions through the dynamics of adaptive cycles : Evolution of the Finnish agrifood system
2023
CONTEXT The escalating sustainability problems of the current agrifood regime call for a radical, systemic transformation. Such a transformation implies a move into a new stability domain, defined by a new set of systemic attractors. These transformations can be conceptualised as regime shifts. OBJECTIVE In this study, we explored the history of the Finnish agrifood system in order to learn from the past transformations of the system and to inform the current attempts to steer its development in a more sustainable direction. METHODS We conducted a qualitative analysis on literature discussing the history of the Finnish agrifood system by utilising the concept of the adaptive cycle, which ca…

The roles of job and worker restructuring in aggregate wage growth dynamics
2019
We propose an approach for measuring and analyzing the dynamics of the standard aggregate wage growth of macro statistics with micro data. Our method decomposes the aggregate wage growth into the wage growth of job stayers and into various terms related to job and worker restructuring. This method produces explicit expressions with clear interpretations for the various restructuring components. Using comprehensive longitudinal employer–employee data, we study how job and worker restructuring influence the aggregate wage growth and its cyclicality. The results highlight the importance of drawing a sharp distinction between job and worker restructuring in the analysis of aggregate wage growth…
