Regenerating small and medium sized stations in Italian inland areas by the opportunity of the cycle tourism, as territorial infrastructure

This study aims at demonstrating how cycle tourism could activate a regeneration of small and medium sized stations in inland areas, able to involve also territorial and urban areas hosting these stations. Starting point of this research is the issue of the small and medium sized Italian stations, mostly unused even if they are still active as rail service. Since control of trains’ traffic is organized only in bigger railway yards, small stations are gradually becoming empty containers: ghost stations, without any railway personnel. Thanks to the potentiality of the cycle tourism, riding slow through landscapes, it becomes possible to valorize and safeguard this heritage, not only exploiting its potentiality as shiftnode between train and bike, but also imaging a systemic strategy triggering urban, territorial and social reactivation. Main challenge was to experiment how another model of mobility, the cycle tourism, able to promote a territorial project preferring to pass slowly through the inland areas, avoided by the fast infrastructural lines, could contribute in such regeneration process. In order to validate this intuition, it was carried out a project of four stations in proximity of the cycle tourist path VENTO, along the Po River. These stations were transformed in “green mobility hubs”, where shifting from train to bicycle and vice versa. This becomes the occasion to imagining new functions hosted in empty spaces of stations (both internal and external): they will provide cycle tourists with territorial info and specific services, such as repair areas and bikes and baggage safekeeping and both tourists and local inhabitants with social activities in order to bring them to live again station’s area. These functions want to generate an expectation, both in tourists and local people, to rediscover the territory around: in this way stations reassume their role of urban and territorial gates

Mount control system of the ASTRI SST-2M prototype for the Cherenkov Telescope Array

The ASTRI SST-2M telescope is an end-to-end prototype proposed for the Small Size class of Telescopes (SST) of the future Cherenkov Telescope Array (CTA). The prototype is installed in Italy at the INAF observing station located at Serra La Nave on Mount Etna (Sicily) and it was inaugurated in September 2014. This paper presents the software and hardware architecture and development of the system dedicated to the control of the mount, health, safety and monitoring systems of the ASTRI SST-2M telescope prototype. The mount control system installed on the ASTRI SST-2M telescope prototype makes use of standard and widely deployed industrial hardware and software. State of the art of the control and automation industries was selected in order to fulfill the mount related functional and safety requirements with assembly compactness, high reliability, and reduced maintenance. The software package was implemented with the Beckhoff TwinCAT version 3 environment for the software Programmable Logical Controller (PLC), while the control electronics have been chosen in order to maximize the homogeneity and the real time performance of the system. The integration with the high level controller (Telescope Control System) has been carried out by choosing the open platform communications Unified Architecture (UA) protocol, supporting rich data model while offering compatibility with the PLC platform. In this contribution we show how the ASTRI approach for the design and implementation of the mount control system has made the ASTRI SST-2M prototype a standalone intelligent machine, able to fulfill requirements and easy to be integrated in an array configuration such as the future ASTRI mini-array proposed to be installed at the southern site of the Cherenkov Telescope Array (CTA)

Dermoscopy patterns of fibroepithelioma of pinkus

Background: Fibroepithelioma of Pinkus ( FeP) is a rare variant of basal cell carcinoma that may clinically mimic a number of benign skin tumors. While the dermoscopic features of basal cell carcinoma have been studied extensively, little is known about the dermoscopic features of FeP. Observations: Retrospective evaluation of clinical records and digital clinical dermoscopic images of 10 histopathologically proved FePs ( 6 nonpigmented and 4 pigmented) was performed. Clinically, no FeP was correctly identified and, in half of all patients, a clinical differential diagnosis of purely benign skin lesions was made. Dermoscopy enabled the correct diagnosis in 9 of 10 FePs, based on the presence of fine arborizing vessels, either alone or associated with dotted vessels, and white streaks ( in 100%, 70%, and 90% of lesions, respectively). In the 4 pigmented FePs, a structureless gray- brown area of pigmentation and variable numbers of gray- blue dots were observed, in addition. Conclusions: Dermoscopy is helpful in diagnosing FeP and in differentiating this variant of basal cell carcinoma from other benign skin tumors commonly included in the clinical differential diagnosis. This presumes, however, that dermoscopy is used as a first- line examination for all skin lesions, not only for those that are clinically suspect

Outcome of laparoscopic gastric bypass in obese and diabetic patients: when surgery fails.

BACKGROUND: The beneficial effects of bariatric surgery on diabetes and obesity have been widely demonstrated in literature. The aim of our study was to evaluate the rate of failure of laparoscopic gastric bypass both in terms of weight loss and metabolic remission after one follow-up year. METHODS: A longitudinal, multicentric prospective study was carried out on 771 patients affected by pathological obesity. The following parameters were recorded for each patient before surgery: anthropometric, metabolic, social, smoking habits and previous failure of other bariatric procedures. After 1 follow-up year, final weight, final BMI, final percentage of lost excess body weight and percentage of lost BMI were evaluated. RESULTS: Statistical analysis showed a correlation between BMI > 50 Kg/m2 , presence of metabolic syndrome, presence of diabetes, gastric pouch volume greater than 60 ml and failure of weight loss outcome. Statistical analysis of metabolic failure has recognized a high preoperative HbA1c % value as a statistically significant negative predictive factor. CONCLUSIONS: Bariatric Surgery is the most effective treatment for weight loss and metabolic improvement. However, in our study, surgery did not achieve the expected outcome in patients with specific metabolic, anthropometric and surgical characteristics (BMI > 50 Kg/m2, presence of metabolic syndrome, presence of T2DM with high preoperative HbA1c % level and gastric pouch volume greater than 60 ml

The ASTRI SST-2M prototype for the Cherenkov Telescope Array: Prototype technologies goals and strategies for the future SST

The Cherenkov Telescope Array (CTA) observatory will represent the next generation of Imaging Atmospheric Cherenkov Telescope. Using a combination of large-, medium-, and small-scale telescopes (LST, MST, SST, respectively), it will explore the Very High Energy domain from a few tens of GeVup to about few hundreds of TeV with unprecedented sensitivity, angular resolution and imaging quality. In this framework, the Italian ASTRI program, led by the Italian National Institute of Astrophysics (INAF) developed a 4-meter class telescope, which will adopt an aplanatic, wide-field, double-reflection optical layout in a Schwarzschild- Couder configuration. Within this program INAF assigned to the consortium between Galbiati Group and EIE Group the construction, assembly and tests activities of the prototype named ASTRI SST-2M. On the basis of the lesson learnt from the prototype, other telescopes will be produced, starting from a re-design phase, in order to optimize performances and the overall costs and production schedule for the CTA-SST telescope. This paper will firstly give an overview of the concept for the SST prototype mount structure. In this contest, the technologies adopted for the design, manufacturing and tests of the entire system will be presented. Moreover, a specific focus on the challenges of the prototype and the strategies associated with it will be provided, in order to outline the near future performance goals for this type of Cherenkov telescopes employed for Gamma ray science
