Landscape Of[f] Limits
No full textThe essay explores the evolving and increasingly complex field of landscape architecture, emphasizing its plural and interdisciplinary nature. The author highlights how contemporary landscape practice must account for layered and dynamic relationships between visible and invisible forces, human and non-human agents, and macro- and micro-scale processes. Time, particularly in the context of the Anthropocene, is positioned as a crucial dimension that reshapes how we perceive and engage with landscapes.
Protasoni calls for a shift in perspective, where the landscape architect is not external to the context but embedded within it—as a professional, intellectual, and living being. This involvement demands not only technical skill but also ethical and interpretive engagement, acknowledging that transformation processes involve diverse and often conflicting interests, norms, and representations. The essay argues for a renewed ecological and ethical commitment in landscape design, one that abandons rigid binaries (e.g., nature vs. human) and embraces a networked understanding of environmental responsibility. The Landscape Of[f] Limits program, within this framework, is proposed as a platform for this new, inclusive approach to landscape transformatio
Anharmonic calculations of vibrational spectra for molecular adsorbates : A divide-and-conquer semiclassical molecular dynamics approach
No full textMolecular adsorption on solid surfaces and how the molecular vibrational properties are affected by the interaction with the surface is a widely studied phenomena not only for academic knowledge but also for potential applications. In the present work, to provide new theoretical insight we aim in overcoming the harmonic approximation by extending our divide-and-conquer semiclassical molecular dynamics approach [1] to the adsorption problem. Relying on a standard Born-Oppenheimer classical trajectory of the full dimensional surface-adsorbate system, we propagate at the semiclassical level the adsorbate modes and the more important coupled surface ones. In this way we are able to account with a contained computational effort not only for anharmonicities, but also for quantum nuclear effects, such as overtones and combination bands, even for these systems where there are a large number of degrees of freedom.
TiO2 is one of the most promising metal oxide for photocatalitic applications, especially for the Anatase(101) facet. Consequently, we validated our approach for CO, NO and H2O adsorbed on the aforementioned surface, and compare our semiclassical results against the harmonic estimates and the classical power spectra, which are computed on top on the same trajectory that we used for the semiclassical simulations [2]. Since infrared spectra for H2O adsorbed on Anatase(101) are of difficult interpretation, we will give some new physical insight by applying our approach to this problem [3].

La cirrosi epatica
No full textLiver cirrhosis is a chronic degenerative disease which is the result of a chronic, recurrent liver damage caused by different agents such as virus B and virus C, alcohol, drugs, autoimmune mechanisms or genetic disorders. The cirrhotic liver presents a diffuse alteration of the histological architecture with nodules and intense fibrosis. To date, the diagnosis of cirrhosis does not require liver biopsy in most cases, because symptoms and signs of portal hypertension combined with the ultrasonographic morpho logical evidences are enough. Cirrhosis can be compensated or decompensated. In the former condition the patient is often asymptomatic, whereas in the latter there are one or more complications such as asci tes, encephalopathy, variceal bleeding or jaundice. Complications needs to be treated by specific thera pies, but the unique treatment which can substantially improve patient survival is liver transplantation. Many cirrhotics die because of liver failure or portal hypertension-related complications but a similar number die because of hepatocarcinoma (HCC). HCC occurs in about 3% of patients every year, and it is estimated to involve at least 40% of patients during the natural history of the disease
