RF-based locating of mobile objects
No full textMisplaced items in retail stores lead to inaccurate inventory assumptions, unsatisfied customers, lost sales and lower revenues of up to 10%. Real-Time Locating Systems (RTLS) however, offer a solution to locate items in a defined space such as a retail store. The RTLS market offers a vast number of available solutions and technologies. Analysts forecast a strong growth of the RTLS market. Unfortunately the majority of users - especially in retail - are still waiting for cheaper offerings. Locating based on passive RFID is a promising low-cost approach for retail applications. This paper describes the current state-of-The-Art in RTLS and shows a use-case of locating garments in retail applications
The use of human adipose-derived stem cells in the treatment of physiological and pathological vulvar dystrophies
No full text“Vulvar dystrophy” is characterized by chronic alterations of vulvar trophism, occurring in both physiological (menopause) and pathological (lichen sclerosus, vulvar graft-versus-host disease) conditions. Associated symptoms are itching, burning, dyspareunia and vaginal dryness. Current treatments often do not imply a complete remission of symptoms. Adipose-Derived Stem Cells (ADSCs) injection represents a valid alternative therapy to enhance trophism and tone of dystrophic tissues. We evaluated efficacy of ADSCs-based therapy in the dystrophic areas. From February to April 2013 we enrolled 8 patients with vulvar dystrophy. A biopsy specimen was performed before and after treatment. Digital photographs were taken at baseline and during the follow-up. Pain was detected with Visual Analogue Scale and sexual function was evaluated with Female Sexual Function Index. All patients received 2 treatments in 3 months. Follow-up was at 1 week , 1 and 3 months, and 1 and 2 years. We obtained a significant vulvar trophism enhancement in all patients, who reported pain reduction and sexual function improvement. Objective exam with speculum was easy to perform after treatment. We believe ADSCs-based therapy finds its application in the treatment of vulvar dystrophies, since ADSCs could induce increased vascularization due to their angiogenic properties and tissue trophism improvement thanks to their eutrophic effect
Analysis, simulation and optimization of the milking process in a cowshed for the production of Parmigiano Reggiano
No full textThe aim of this study is to optimize the milking process of a cowshed, located near Parma (Italy), which provides milk to some dairy companies, for the production of Parmigiano Reggiano cheese. The ultimate goal of the analysis is to reduce the time required for milking operations, thus optimizing the whole management of the farm processes. A discrete-event simulation model is designed under Simul8TM to reproduce the main processes of the cowshed and the movements of the animals inside the cowshed, before and after milking. The model exploits real data collected from the direct observation of the farm and is validated by comparing the results provided with the real performance of the milking activities. Then, it is used to test two new configurations of the cowshed layout and to assess their performance, in terms of the total time required for milking. Interesting savings in the total milking time are foun
I livelli essenziali delle prestazioni
No full textL'articolo esamina criticamente, alla luce della copiosa giurisprudenza della Corte costituzionale in materia di determinazione dei livelli essenziali delle prestazioni concernenti i diritti civili e sociali di cui all'art. 117 Cost., le previsioni contenute nel d.lgs. n. 150/2015, attuativo della delega contenuta nella l. n. 183/2014, in materia di riforma dei servizi per l'impiego e politiche attive del lavoro, con particolare riferimento a quelle che definiscono i livelli essenziali delle prestazioni concernenti i servizi per l'impiego da garantire in modo uniforme su tutto il territorio nazionale
Effect of enzymatic debridement with two different collagenases versus mechanical debridement on chronic hard-to-heal wounds
No full textA chronic ulcer is usually defined as an injury that does not spontaneously evolve towards healing and does not progress through normal healing stages such as inflammation, proliferation and remodelling. This study was designed in order to compare two types of collagenases with mechanical debridement alone. It was thus possible to evaluate their differences in terms of pain and debridement efficacy. Patients were divided into three groups: 30 patients were daily dressed using an ointment based on collagenase produced by Vibrio alginolyticus (B group), 30 patients were daily dressed using an ointment based on a collagenase preparation derived from Clostridium histolyticum (N group) and 30 patients underwent classical mechanical debridement (M group). Complete wound healing over a period of 8 weeks occurred in 24 patients (27%) out of 90;10 patients belonging to the B group, 8 patients to the N group and 6 patients to the M group. This study was performed in order to highlight the differences between two commercially available collagenase-based ointments in comparison with mechanical debridement alone. At the final time point of week, the difference in the percentage of debridement was not statistically significant in all groups, but at 4 weeks, the debrided area in the B group was larger with respect to the N and M groups, suggesting a more rapid wound bed cleansing process. On the basis of our experience, collagenase derived from V. alginolyticus with hyaluronic acid showed chemical and physical properties that make it a product of great manageability and ensure the protection of peri-wound skin. Moreover, less pain was experienced by the patients

No full textIl saggio - che riproduce la relazione presentata al Convegno su "Infortuni sul lavoro. Il nodo delle responsabilità", organizzato dal Dipartimento di Scienze giuridiche dell'Università di Udine in occasione della 4° edizione del "Premio Giuseppe Lombardi" (Udine, 10 October 2014) - analizza i fondamenti delle responsabilità del datore di lavoro e dei dirigenti in materia di salute e sicurezza sul lavoro sottolineando in particolare l'importanza della dimensione organizzativa nel d.lgs. n. 81/2008
