Prediction of Maxwell – Stefan diffusion coefficients in polymer – multicomponent fluid systems
2014
Abstract Calculations of mass fluxes in multicomponent fluids based on the system of generalized Maxwell–Stefan equations (GMSE) is preferably used because Maxwell–Stefan (M–S) diffusion coefficients are symmetrical and have a clear physical meaning, as they reflect the binary friction forces between compounds in the system. For the calculation of the mass transport of a multicomponent fluid in the polymer basing on GMSE, it is necessary to have M–S diffusion coefficients. This paper proposes a method that allows their calculation using widely available self-diffusion coefficients and binary diffusion coefficients for infinitely diluted mixtures. The proposed method was compared with the me…
Family Structure and Subjective Economic Well-Being: Some New Evidence
2013
The paper investigates the main socio-demographic and economic determinants of subjective economic well-being in different typologies of households. Previous studies have used dummy variables to explore the effect of family structure. In this paper, however four different models—one for each family typology—have been estimated to test if each selected explanatory variable is significant and how it acts in determining the level of subjective economic well-being. To achieve this, we apply an under-used logit model—the partial proportional ordered model. Our analysis, based on data from the 2005 Italian Survey on Income and Living Conditions highlights the main variables affecting the subjecti…
The determinants of subjective economic well-being: an analysis on Italian-Silc data
2011
Using Italian data on Income and living conditions for the year 2005, the paper investigates the main determinants of households’ subjective economic well-being by means of a Partial Proportional Ordered Logit Model. According to a joint subjective and objective perspective of analysis, we use as dependent variable the perceived ability of households to make ends meet. Whereas, we use as explanatory variables some objective aspects of living conditions relating to housing, financial equilibrium, possession of durables and quality of residence place and some socio-demographic characteristics. The empirical results show that the financial strain is the most relevant dimension of living condit…
The ‘Difficult’ Polyp: Pitfalls for Endoscopic Removal
2012
Adenomatous polyps are early neoplasias of colorectal cancer (adenoma-carcinoma sequence). The majority of adenomas or early invasive cancers (T1sm1) can be resected by endoscopy. Endoscopic resection techniques include classic loop polypectomy, endoscopic mucosectomy with preceding lifting of the (almost flat) lesion, endoscopic submucosal dissection and transanal microsurgical resection, an alternative to endoscopic submucosal dissection in the rectum. Endoscopic polyp removal should always aim to resect the lesion in ‘one piece’ and avoid, whenever possible, ‘piecemeal resection’. One-piece polypectomy is the basis for a precise histopathological analysis and for proving complete removal…
A computational model of postprandial adipose tissue lipid metabolism derived using human arteriovenous stable isotope tracer data
2019
Given the association of disturbances in non-esterified fatty acid (NEFA) metabolism with the development of Type 2 Diabetes and Non-Alcoholic Fatty Liver Disease, computational models of glucose-insulin dynamics have been extended to account for the interplay with NEFA. In this study, we use arteriovenous measurement across the subcutaneous adipose tissue during a mixed meal challenge test to evaluate the performance and underlying assumptions of three existing models of adipose tissue metabolism and construct a new, refined model of adipose tissue metabolism. Our model introduces new terms, explicitly accounting for the conversion of glucose to glyceraldehye-3-phosphate, the postprandial …
A Successful Aging Model Based on Personal Resources, Self-Care, and Life Satisfaction
2021
The most internationally studied models of successful aging defend that there are several pillars for a good aging: absence of disease, good cognitive and physical function, a high commitment and social activity, social capital, personal resources, life satisfaction, and spirituality. This study examines the relationships between personal resources, perceived social support, hope, spirituality, self-care and subjective well-being variables, as bases for a successful aging. One thousand and sixteen community-dwelling Spanish adults, aged 55-92 years, participated in the study. Information on variables assessed was collected using self-reported questionnaires. Confirmatory Factor Analyses and…
The prevalence of abnormal glucose regulation in patients with coronary artery disease across Europe. The Euro Heart Survey on diabetes and the heart.
2004
Aim The objective behind the Euro Heart Survey on diabetes and the heart was to study the prevalence of abnormal glucose regulation in adult patients with coronary artery disease (CAD). Methods and results The survey engaged 110 centres in 25 countries recruiting 4196 patients referred to a cardiologist due to CAD out of whom 2107 were admitted on an acute basis and 2854 had an elective consultation. Patient data were collected via a web-based case record form. An oral glucose tolerance test (OGTT) was used for the characterisation of the glucose metabolism. Thirty-one per cent of the patients had diabetes. An OGTT was performed on the 1920 patients without known diabetes, of whom 923 had a…
Cancer in children and adolescents in Europe: Developments over 20 years and future challengers
2006
This special issue contains 18 articles describing population-based analyses of incidence and survival for cancer among children and adolescents in Europe over the period 1978-1997. The analyses were derived from the large database of the ACCIS project (Automated Childhood Cancer Information System), which was built through collaboration of 62 population-based cancer registries in 19 European countries. Data on 88,465 cancers in children and 15,369 in adolescents (age 15-19 yrs) were included in the various analyses, making this the largest database on cancer in these age-groups in the world. National data were grouped into five European regions to allow comparisons of incidence and surviva…
Does being involved by doctors satisfy patients' fundamental psychological needs? A study on a large European sample
2022
The present work was aimed at investigating whether the patients’ involvement by their healthcare providers may satisfy patients’ fundamental psychological needs (i.e. self-esteem, belonging, control, meaningful existence), which in turn, can impact their psychological well-being. Based on the European Quality of Life Survey data, the sample included 10,427 European adults who, in the last 12 months, visited GP/family doctors and hospital/medical specialists. Among them, 51.3% declared to have a chronic disease. Results showed that the experience of being involved by GP/family doctors and hospital/medical specialists had a positive effect on psychological well-being and that this effect was…
Emotional intelligence and self-efficacy: effects on psychological well-being in college students.
2013
AbstractThe present paper examined the role of perceived emotional intelligence-EI- (measured by adaptations of the Trait Meta-Mood Scale - TMMS, Salovey, Mayer, Goldman, Turvey, & Palfai, 1995) as a predictor of life satisfaction and mental health. We explored the unique contribution of EI dimensions (Attention, Clarity and Repair) on individuals’ psychological well-being, after controlling for the influence of general self-efficacy and socio-demographic variables (age, gender and culture). Data was collected from a sample of 1078 Spanish, Mexican, Portuguese and Brazilian undergraduate students (Mage = 22.98; SD = 6.73) and analyzed using hierarchical multiple regressions. Results ind…
