Breath of New Life for the Ruins of Villa Aprilia of Lancia Family in the Italian Alps (1800 m)
No full textVilla Gilodi, later Villa Aprilia, was built by architect Costantino Gilodi in the Belle Epoque style in 1906, equipped with heating, running water and electricity. Its position in the North-Western Alps at an elevation of 1824 m, in a hard-to-reach area, makes this construction unique. The villa was built using local stone masonry and sits on a leveled ground supported by massive embankments with buttresses. This location is rich in historical significance. After architect Gilodi passed away, the Lancia family, owners of the renowned car brand, acquired the villa. During World War II, the region where the villa sits was an escape route to Switzerland and battle ground between partisans and fascists. In 1944, the villa was set on fire and abandoned. The villa has been in a state of ruin ever since and is deteriorating progressively due to the harsh weather and lack of maintenance. Despite this, the masonry proved to be extremely durable over the decades. The architecture is still recognizable and the walls are standing tall, together with the portico. Fortunately, the municipality where it is located, Bannio Anzino, decided to buy the Villa to give it a new life, compatible with the enchanting natural theater in which it is inserted. The municipality is looking into carrying out a sustainable intervention reclassifying it for a new use. This manuscript intends to tell the past, present and potential future of this exceptional masonry construction in the context of its historical and architectural significanc

No full textDistribution of minor and trace elements among Italian chondritic meteorites
No full textThe cobalt, nickel, zinc, selenium, rubidium and cesium content was determined in eight Italian chondritic meteorites by destructive neutron activation analysis. The chemical procedure involves only a few steps: sample dissolution, radiochemical separation of the elements on inorganic adsorbers (copper grains and zinc ferrocyanide)andonDowex 2x8 anionic resin. Element contents are reported and discussed. Precision and accuracy of the analytical method are given as well. Results and average class values are compared with existing values in the literature. Possible correlations between pairs of elements (Co - Ni, Zn - Se and Rb - Cs) in the examined chondrites, were investigated and discussed
A MEMS Reconfigurable Quad-Band Class-E Power Amplifier for GSM Standard
No full textIn this work we present a reconfigurable mid-power class-E power amplifier (PA) operating at ~900 MHz and ~1800 MHz (GSM standard) realized hybridizing one chip manufactured in AMS 0.35 mum CMOS technology and one MEMS sub-network. The CMOS chip realizes the active part of the circuit, whereas the MEMS block (realized in FBK technology) implements a reconfigurable impedance matching network (MN) that transforms the 50 Omega antenna load to the 12 Omega impedance required by the PA in order to deliver 20 dBm output power in both the GSM operating frequency bands. The prototype of the MEMS/CMOS PA we realized delivers 20 dBm with 38% and 26% drain efficiencies at 900 MHz and 1800 MHz, respectively, demonstrating to be a feasible option compared to standard commercial solutions

No full textLabel-Free Optical Sensing and Medical Grade Resins: An Advanced Approach to Investigate Cell–Material Interaction and Biocompatibility
No full text: The Corning Epic® label-free (ELF) system is an innovative technology widely used in drug discovery, immunotherapy, G-protein-associated studies, and biocompatibility tests. Here, we challenge the use of ELF to further investigate the biocompatibility of resins used in manufacturing of blood filters, a category of medical devices representing life-saving therapies for the increasing number of patients with kidney failure. The biocompatibility assays were carried out by developing a cell model aimed at mimicking the clinical use of the blood filters and complementing the existing cytotoxicity assay requested by ISO10993-5. Experiments were performed by putting fibroblasts in both direct contact with two types of selected resins, and indirect contact by means of homemade customized well inserts that were precisely designed and developed for this technology. For both types of contact, fibroblasts were cultured in medium and human plasma. ELF tests confirmed the biocompatibility of both resins, highlighting a statistically significant different biological behavior of a polyaromatic resin compared to control and ion-exchanged resin, when materials were in indirect contact and soaking with plasma. Overall, the ELF test is able to mimic clinical scenarios and represents a promising approach to investigate biocompatibility, showing peculiar biological behaviors and suggesting the activation of specific intracellular pathways
