Towards a Guidance System to Aid in the Dosimetry Calculation of Intraoperative Electron Radiation Therapy
2015
In Intraoperative Electron Radiation Therapy (IOERT), the lack of specific planning tools limits its applicability, the need for accurate dosimetry estimation and application during the therapy being the most critical. Recently, some works have been presented that try to overcome some of the limitations for establishing planning tools, though still an accurate guidance system that tracks, in real-time, the applicator and the patient is needed. In these surgical environments, the acquisition of an accurate 3D shape of the patient’s tumor bed in real-time is of high interest, as current systems make use of a 3D model acquired before the treatment. In this paper, an optical-based system is pre…
Istota budżetu gminy w gospodarce komunalnej i mieszkaniowej
2016
The municipality independently manages the finances. The plan of incomes and expenses the municipality passed a by law for a period of one calendar year. The draft budget is developing management based on the budget law and the guidelines of the municipal council, the municipal council adopts while. The revenues of local government units are public funds collected by these units from individuals, legal persons and entities without legal personality, as well as funds received from the state budget in the form of subsidies and grants for the implementation of specific tasks. However, the revenue received is not always sufficient to meet all the needs of the residents. Municipal authorities ha…

Skin surveillance attitudes and behaviors in relation to skin checks for early signs of skin cancer in a sample of secondary school students and teac…
2012
<p><strong>Background</strong>: Malignant melanoma (MM) can be readily treated in its earliest stages: survival rate, when detected early, is up to 95,0%. This justifies investigations on contributive factors and measures for precocious detection of skin tumors to improve early detection and to increase survival rates. The purpose of this survey was to collect information about knowledge, attitudes and behaviors on prevention in relation to skin checks for early signs of skin cancer on a sample of secondary school students and teachers.</p><p><strong>Methods</strong>: A sample of secondary school students and teachers from Palermo, was recruited usi…
The commitment of the GISIO-SItI to contrast Healthcare- Associated Infections and the experience of the prevalence studies in Sicily
2018
Surveillance of Healthcare-Associated Infections (HAIs) is essential to improve the quality of health services. The aim of this paper is to report the commitment of the Italian Study Group of Hospital Hygiene (GISIO) of the Italian Society of Hygiene, Preventive Medicine and Public Health (SItI) describing some experiences to contrast HAIs and antimicrobial resistance. Particularly, the commitment to contrast HAIs in intensive care with the SPIN-UTI project - Italian Nosocomial Infections Surveillance in ICUs, and in surgery with the ISCHIA project - Infections of Surgical Site in Arthroplasty Interventions - were described. Furthermore, some activities conducted in Sicily using repeated pr…
Monitoraggio e percezione delle esperienze formative internazionali tra gli specializzandi italiani in igiene e medicina preventiva. Indagine condott…
2013
Introduzione Molti studi hanno dimostrato che le esperienze formative internazionali (International Health Electives - IHE) contribuiscono all'acquisizione di conoscenze e competenze fondamentali per i futuri professionisti in Sanità proprio attraverso l'opportunità di confronto fra sistemi sanitari e contesti socio-culturali differenti. Sebbene le IHE siano in crescita, non ci sono dati che riguardino quelle svolte dagli specializzandi italiani in Igiene. L'obiettivo dello studio è di raccogliere informazioni sulle loro pregresse esperienze formative internazionali e di comprendere motivazioni ed eventuali criticità relative alla decisione di effettuare una IHE. Materiali e metodi Gli spec…
The barriers dentists face to communicate cancer diagnosis:self-assessment based on SPIKES protocol
2022
This study aimed to characterize the barriers faced by Brazilian dentists to deliver bad news (DBN) about oral and oropharyngeal cancer diagnoses to patients by using a questionnaire based on the guidelines of the SPIKES protocol. This was an observational cross-sectional study. The questionnaire contained 27 questions based on the SPIKES protocol, which were answered in the SurveyMonkey platform. A total of 186/249 dentists answered the questionnaire. The main specialties reported were 36.02% oral medicine, 21.5% oral pathology, and 9.13% oral and maxillofacial surgery. A total of 44.6% expressed concern about the patient?s emotional reactions, and 46.24% of respondents had never participa…
Cardiac cycle and respiration phase affect responses to the conditioned stimulus in young adults trained in trace eyeblink conditioning
2022
Rhythms of breathing and heartbeat are linked to each other as well as to rhythms of the brain. Our recent studies suggest that presenting the conditioned stimulus during expiration or during the diastolic phase of the cardiac cycle facilitates neural processing of that stimulus and improves learning an eyeblink classical conditioning task. To date, it has not been examined whether utilizing information from both respiration and cardiac cycle phases simultaneously allows even more efficient modulation of learning. Here we studied whether the timing of the conditioned stimulus to different cardiorespiratory rhythm phase combinations affects learning trace eyeblink conditioning in healthy you…
Evaluation of asset replacement strategies considering economic cycles: lessons from the machinery rental business
2015
Contains fulltext : 144492.pdf (Publisher’s version ) (Open Access) In businesses with heavy capital investments, the effective management of assets is crucial, in particular in the fleet rental business where assets are the major source of revenues. One important question in this regard concerns the replacement of used assets and the purchase of new assets. Thus, the objective of this study is to evaluate performance effects of asset replacement strategies. In order to maximise net cash flow of a rental company for construction machinery, a range of scenarios investigating the timing and nature of policies for replacing the fleet are analysed. Simulation findings are then discussed to gene…
Unifying Concepts for Ion-Induced Leakage Current Degradation in Silicon Carbide Schottky Power Diodes
2020
The onset of ion-induced reverse leakage current in SiC Schottky diodes is shown to depend on material properties, ion LET, and bias during irradiation, but not the voltage rating of the parts. This is demonstrated experimentally for devices from multiple manufacturers with voltage ratings from 600 V to 1700 V. Using a device with a higher breakdown voltage than required in the application does not provide increased robustness related to leakage current degradation, compared to using a device with a lower voltage rating. peerReviewed
