Everyday life in old age: past, present, and future
2018
Aims: To explore how older Norwegian women living at home experience ageing, and how their everyday life has been influenced by their encounters with the challenges of life. Methods: A qualitative design, interviewing ten women age 90 or older, was employed. Results: The overall theme of the findings is how everyday life in old age is influenced by past, present and future. The subcategories focus on (a) changes in daily life, (b) giving an account of life as it is, (c) various perceptions of experienced loss, and finally, (d) thoughts about the future. Conclusions: Older women need the opportunity to reflect upon their past, present and future existence to have a good everyday life in old …
Psychometric properties of Antonovsky's 29-item Sense of Coherence scale in research on older home-dwelling Norwegians.
2015
Aim: The aim of this study was to test the homogeneity and construct validity of the Sense of Coherence 29-item scale (SOC-29) among older home-dwelling Norwegians. Methods: A postal questionnaire, consisting of background variables, five health-related questions, the SOC-29, and three other instruments measuring mental health, self-care ability, and risk for undernutrition, was sent to 6033 home-dwelling older people (65+ years) in southern Norway. A total of 2069 participants were included. Homogeneity was assessed with Cronbach’s alpha coefficient and item-to-total correlations. The construct validity was assessed with “the known-groups technique,” a linear stepwise regression analysis …

Healthy design and urban planning strategies, actions, and policy to achieve salutogenic cities
2018
Starting from a previous experience carried out by the working group “Building and Environmental Hygiene” of the Italian Society of Hygiene and Preventive Medicine (SItI), the aim of the present work is to define new strategic goals for achieving a “Healthy and Salutogenic City”, which will be useful to designers, local governments and public bodies, policy makers, and all professionals working at local health agencies. Ten key points have been formulated: 1. climate change and management of adverse weather events; 2. land consumption, sprawl, and shrinking cities; 3. tactical urbanism and urban resilience; 4. urban comfort, safety, and security perception; 5. strengths and weaknesses of ur…
Determination of concentrations in ternary and quaternary molecular gas mixtures using femtosecond Raman spectroscopy
2002
European Conference on Nonlinear Optical Spectroscopy MAR 18-19, 2002 VILLIGEN, SWITZERLAND; Measurements of concentrations in gas mixtures of three and four molecular components are presented. They rely on a femtosecond time-resolved pump-probe technique based on Raman-induced polarization spectroscopy. The rotational time response of the molecular gas mixture is measured as a function of the pump-probe time delay. No selective frequency tunability is needed as the molecular rotational spectra are excited within the laser bandwidth. The results obtained from experiments performed at room temperature in N2O-CO2-N2 and N2O-CO2-O2-N2 mixtures are presented and the accuracy of the method is di…
Concentration measurements in molecular gas mixtures with a two-pump pulse femtosecond polarization spectroscopy technique
2001
0021-9606; Recently, we have demonstrated the ability of the Raman-induced polarization spectroscopy (RIPS) technique to accurately determine concentration or polarizability anisotropy ratio in low-pressure binary molecular mixtures [E. Hertz, B. Lavorel, O. Faucher, and R. Chaux, J. Chem. Phys. 113, 6629 (2000)]. It has been also pointed out that macroscopic interference, occurring when two revivals associated to different molecules time overlap, can be used to achieve measurements with picosecond time resolution. The applicability of the technique is intrinsically limited to a concentration range where the signals of both molecules are of the same magnitude. In this paper, a two-pump puls…
Infracyanine Green vs. Brilliant Blue G in Inverted Flap Surgery for Large Macular Holes: A Long-Term Swept-Source OCT Analysis
2020
Background and Objectives: To compare the long-term toxicity of infracyanine green (IFCG) to brilliant blue G (BBG) in inverted internal limiting membrane flap surgery (I-ILMFS) for large, full-thickness macular holes (FTMHs). Materials and Methods: Prospective randomized study including 39 eyes with &ge

Coherence absorption and condensation induced by thermalization of incoherent nonlinear fields
2008
We show that a conservative system of incoherent nonlinear waves exhibits, as a rule, an irreversible process of coherence transfer, in which the incoherence of the system is absorbed by the small-amplitude field, thus allowing the high-amplitude field to evolve towards a highly condensed coherent state. This process of coherence absorption results from the natural thermalization of the fields to a thermodynamic equilibrium state. The theory reveals that, contrary to a classical gas system, a wave system does not satisfy an equipartition of energy among the particles. Such a distinctive feature is the key property underlying the existence of the coherence absorption process. The coherence a…
