Abstract

Il metodo della rosetta forata è una delle tecniche di analisi delle tensioni residue più utilizzati in campo industriale. Il metodo è abbastanza accurato per tensioni costanti, mentre nel caso di tensioni variabili nello spessore del componente esaminato diverse cause di incertezza devono essere attentamente esaminate. Poiché nella valutazione numerica dei coefficienti di influenza il foro è considerato perfettamente cilindrico e privo di raccordo, una sorgente di errore è costituita dal raggio di raccordo al fondo foro. In questa memoria viene studiato l’effetto che il raggio di raccordo ha sulle deformazioni misurate e sulle tensioni calcolate. E’ cosi mostrato come anche piccoli raggi di raccordo possono essere causa di errori significativi sulle tensioni calcolate. Inoltre, è proposto un metodo semplice di correzione degli errori sulle tensioni calcolate.

Abstract

The aim of this study was to analyse the end-of-life topics most frequently discussed by Italian physicians, nurses and psychologists with terminally ill patients and their relatives. Findings were compared with the levels of communication reported by physicians in other countries involved in the EURELD research project, in Europe and elsewhere.An ad hoc questionnaire was prepared to measure levels of communication and administered to 716 professionals (181 physicians, 454 nurses and 81 psychologists) employed in geriatric hospital wards, hospices and nursing homes, or registered with professional associations in the Veneto and Trentino Alto-Adige regions of north-east Italy. Statistical analyses (frequency analysis, multivariate logistic regression) were conducted on data from questionnaires returned by standard mail or email.Communication levels vary for the various end-of-life issues which physicians, nurses and psychologists are required to discuss and the individuals with whom they deal. Italian physicians are more communicative with relatives than with patients, whereas psychologists tend to discuss these problems more with patients than with members of their families. Nurses behave in much the same way with both patients and relatives. By comparison with their colleagues elsewhere in Europe, Italian physicians reveal more evident differences in their willingness to discuss end-of-life issues, depending on whether they are communicating with patients or relatives. Having received bio-ethical training helps physicians communicate with their patients.Communicating is a fundamental part of providing care for terminally ill patients and support for their families. The patient care process involves several kinds of professionals, who are all increasingly called upon to be prepared to discuss the end of a patient's life, and to develop a therapeutic relationship which includes communicating without evading any of the aspects (and problems) relating to this crucial final stage of an individual's life.

100. Cognitive aspects of nociception and pain. Bridging neurophysiology with cognitive psychology

Abstract

The event-related brain potentials (ERPs) elicited by nociceptive stimuli are largely influenced by vigilance, emotion, alertness, and attention. Studies that specifically investigated the effects of cognition on nociceptive ERPs support the idea that most of these ERP components can be regarded as the neurophysiological indexes of the processes underlying detection and orientation of attention toward the eliciting stimulus. Such detection is determined both by the salience of the stimulus that makes it pop out from the environmental context (bottom-up capture of attention) and by its relevance according to the subject's goals and motivation (top-down attentional control). The fact that nociceptive ERPs are largely influenced by information from other sensory modalities such as vision and proprioception, as well as from motor preparation, suggests that these ERPs reflect a cortical system involved in the detection of potentially meaningful stimuli for the body, with the purpose to respond adequately to potential threats. In such a theoretical framework, pain is seen as an epiphenomenon of warning processes, encoded in multimodal and multiframe representations of the body, well suited to guide defensive actions. The findings here reviewed highlight that the ERPs elicited by selective activation of nociceptors may reflect an attentional gain apt to bridge a coherent perception of salient sensory events with action selection processes.
