Introduction: Ego strength represents an important variable that could be predictable about health and compliance in chronic diseases. In this study we propose a new questionnaire, E.F.E. “Ego Functioning Experience”, able to reveal the psychological functioning profile in Hemodialysis patients. The aim of this work, is to underline the existing relations between emotional profile and compliance, whit E.F.E., that may be predictive of a state of psychologycal health in hemodialysis patients. Methods: Study population included 90 hemodialysis patients. The study protocol was made by three psychological tests: the E.F.E. Questionnaire, the DMI, the Self-Liking and Self-Competence Scale. Results: Factor analysis extracts three factors: 1) “Need of Ego support”;2) “Ego activity oriented to treatment”;3) “Ego strength”. The correlation coefficients between the E.F.E. Questionnaire factors (three factors) and other measures, showed a direct correlation with the first factor and “turning against object” TAO of the DMI test (correlation is significant at the 0.001 level) and an inverse relation with set mechanisms of “Principalization”, PRN of the DMI (correlation is significant at the 0.005 level). The correlations of the second and the third factors with other measures, were not statistically significant. No relations were found about other variables. Conclusions: The E.F.E. questionnaire is a simple evaluation to detect hemo-dialysis patients who may need greater attention to the psychological health and therefore the need for treatment such as psychological support. In fact, lower presence of ego strength is indicative of poor compliance to clinical treatment in hemodialysis, but also of worsening of psychiatric symptoms such as demoralization and depressed mood. In conclusion, an increased social support is needed in hemodialysis patient in order to achieve better compliance and achieve a better state of psychological health in chronic hemodialysis patients.

Topography, exhumation, and drainage network evolution of the Apennines

Episodes 2003年第3期26卷 212-216页

The present-day topography of the Italian peninsula results from the interactions between crustal-mantle and surface processes occurring since the Late Miocene. Analysis of exhumation and cooling of crustal rocks, together with Quaternary drainage evolution,helps to unravel the tectonic-morphologic evolution of the Apennines by distinguishing end-member models,and hence describing the orogenic belt evolution. The pattern of regional topography, erosional history and present-day distribution of active deformation suggests that the eastward migrating extensional-compressional paired deformation belts may still control the topogra-phy of the northern Apennines, albeit at slower rates than in the past. Conversely, Quaternary drainage evo-lution in the central and southern Apennines suggests that the topography of these regions underwent a Quaternary regional arching, which is only partly con-sistent with the persisting migration of the compres-sional-extensional pair.

This paper introduces a semi-empirical model to predict the downwash gradient at the horizontal tail of a three-lifting-surface *** superposition principle applied to well established formulations valid for two lifting surfaces is not a reasonable approach to calculate the downwash of a canard-wing-tail layout,and this paper demonstrates that such a basic technique leads to incorrect ***,an ad hoc prediction model is proposed that considers the combined nonlinear effects of canard and main wing inductions on tail downwash,being based on a full factorial design sweep of CFD simulations obtained by varying the main geometrical parameters of the three lifting surfaces.A suitable analytical formula for the downwash gradient is established through a process of data analysis and factor *** presented model extends the validity of the available models for traditional two-lifting-surface designs by means of a correction *** engineering estimation method introduced here exhibits an acceptable accuracy,as well as relatively small prediction errors,and it is suitable for conceptual and preliminary studies of threesurface *** value of this methodology is confirmed by the validation with the results of numerical and experimental investigations on a case study aircraft.

On the criteria to create a susceptibility map to debris flow at a regional scale using Flow-R

引用

Journal of Mountain Science 2017年第4期14卷 621-635页

作者： PASTORELLO Roberta MICHELINI Tamara D'agostino Vincenzo Department of Land EnvironmentAgriculture and Forestry(TeSAF)University of Padova35020 LegnaroItaly

Studies on susceptibility to debris flows at regional scale （ioo-looo km2） are important for the protection and management of mountain areas. To reach this objective, routing models, mainly based on land topography, can be used to predict susceptible areas rapidly while necessitating few input data. In this research, Flow-R model is implemented to create the susceptibility map for the debris flow of the Vizze Valley （BZ, North-Eastern Italy; 134 km^2）. The analysis considers the model application at local scale for three sub-catchments and then it explores the model upsealing at the regional scale by verifying two methods to generate the source areas of debris-flow initiation. Using data of an extreme event occurred in the Vizze Valley （4 August 2012） and historical information, the modeling verification highlights that the propagation parameters are relatively simple to set in order to obtain correct runout distances. A double DTM filtering - using a threshold for the upslope contributing area （0.1 km^2） and a threshold for the terrain-slope angle （15°） provides a satisfactory prediction of source areas and susceptibility map within the geological conditions of the Vizze Valley.
