Shared socioeconomic pathways for climate change research in Finland: co-developing extended SSP narratives for agriculture
2021
AbstractShared socioeconomic pathways (SSPs), developed at global scale, comprise narrative descriptions and quantifications of future world developments that are intended for climate change scenario analysis. However, their extension to national and regional scales can be challenging. Here, we present SSP narratives co-developed with stakeholders for the agriculture and food sector in Finland. These are derived from intensive discussions at a workshop attended by approximately 39 participants offering a range of sectoral perspectives. Using general background descriptions of the SSPs for Europe, facilitated discussions were held in parallel for each of four SSPs reflecting very different c…
Dislocazione infero-mediale del frammento meniscale. Studio con risonanaza magnetica
2005
Definire l'accuratezza diagnostica della Risonanza Magnetica (RM) nella diagnosi di dislocazione infero-mediale del frammento della fibrocartilagine meniscale, Materiale e metodi. Sono stati valutati retrospettivamente gli esami RM del ginocchio, effettuati nel periodo compreso tra dicembre 2002 ed aprile 2004, di 676 pazienti (eta media 32 anni) affetti da patologia traumatica del ginocchio e successivamente sottoposti ad artroscopia, al fine di identificare la presenza di una lesione meniscale a manico di secchio e della dislocazione infero-mediale del frammento meniscale. Gli esami RM sono stati eseguiti con un magnete superconduttivo da 0,5 T utilizzando una bobina ricevente/trasmittent…
HIGH-RESOLUTION ULTRASONOGRAPHY (HRUS) OF THE MENISCAL CYST OF THE KNEE : OUR EXPERIENCE
2007
Purpose. This study was undertaken to assess the diagnostic accuracy of high-resolution ultrasonography (HRUS) in the detection of meniscal cysts. Materials and methods. Over a 2-year period, 1,857 patients underwent magnetic resonance imaging (MRI) of the knee for traumatic or degenerative disorders. All patients with MRI evidence of a meniscal cyst were studied by HRUS. HRUS was also performed on an equal number of patients without MRI evidence of meniscal cyst who were used as a control group. All HRUS examinations were conducted by a radiologist blinded to the MRI findings. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of HRUS were assesse…
Hyperstoichiometric interaction between silver and mercury at the nanoscale.
2012
Breaking through the stoichiometry barrier: As the diameter of silver particles is decreased below a critical size of 32?nm, the molar ratio of aqueous HgII to Ag0 drastically increases beyond the conventional Hg/Ag ratio of 0.5:1, leading to hyperstoichiometry with a maximum ratio of 1.125:1 (see figure). Therein, around 99?% of the initial silver is retained to rapidly form a solid amalgam with reduced mercury.
Quadrature domains for the Helmholtz equation with applications to non-scattering phenomena
2022
In this paper, we introduce quadrature domains for the Helmholtz equation. We show existence results for such domains and implement the so-called partial balayage procedure. We also give an application to inverse scattering problems, and show that there are non-scattering domains for the Helmholtz equation at any positive frequency that have inward cusps.
Scanning Tunneling Spectroscope Use in Electrocatalysis Testing
2010
Published version of an article from the journal: Materials (1996-1944). Also available from publisher: http://dx.doi.org/10.3390/ma3063675 The relationship between the electrocatalytic properties of an electrode and its ability to transfer electrons between the electrode and a metallic tip in a scanning tunneling microscope (STM) is investigated. The alkaline oxygen evolution reaction (OER) was used as a test reaction with four different metallic glasses, Ni78Si8B14, Ni70Mo20Si5B5, Ni58Co20Si10B12, and Ni25Co50Si15B10, as electrodes. The electrocatalytic properties of the electrodes were determined. The electrode surfaces were then investigated with an STM. A clear relationship between the…
Design of anisotropic nanostructures for light control
2018
El rápido avance en métodos de micro- y nanofabricación, tanto teórica como experimentalmente, han hecho posible a día de hoy que podamos controlar el flujo de luz con una precisión sin precedentes. Los metamateriales y las metasuperficies son nanoestructuras compuestas a partir de celdas unidad dise˜nadas, de forma que permitan manipular la luz con una respuesta estipulada. Como resultado de esto, los metamateriales han proporcinoado un gran número de posibles aplicaciones nuevas que antes eran inconcebibles. En esta Tesis Doctoral nos hemos centrado en el uso de estos metamateriales excepcionales para conseguir, específicamente, partículas indetectables y también para controlar el modelad…
The urban regeneration of the peripheral areas. The case study of Tor Vergata (Rome, Italy)
2018
The ‘Urban Regeneration of Peripheral Areas’ workshop experimented with an innovative design model for the urban regeneration of Rome. The working method of the workshop is based on diachronic analysis of the evolution of the combined natural history and culture of the area, the architectural, technological, environmental and landscape situation and relation-ship with the surrounding territory. The workshop dealt with the mutual relationships, which run through and characterise the dimensional and relational scales of the environments of metropolitan ecosystems as structures and landscapes. The strategy for urban and territorial integration is left to the procedures and policies of the comm…
