A functional analytic approach to homogenization problems
No full textWe plan to illustrate a functional analytic approach to analyze homogenization problems, which has already been developed for singular perturbation problems in bounded domains with small holes (cf. e.g., Lanza de Cristoforis (Comput Methods Funct Theory 2:1– 27, 2002), Lanza de Cristoforis (Analysis (Munich) 28:63–93, 2008), Lanza de Cristoforis (Complex Var Elliptic Equ 55:269–303, 2010) Lanza de Cristoforis (Rev Mat Comput 25:369–412, 2012)). In the frame of linearized elastostatics and of the Stokes equations, we mention Dalla Riva and Lanza de Cristoforis (Complex Var Elliptic Equ 55:771–794, 2010; Complex Anal Oper Theory 5:811–833, 2011), and Dalla Riva (Complex Var Elliptic Equ 58:231–257, 2013). Later on, such an approach has been exploited for the analysis of problems in unbounded perforated domains with a fixed periodic structure, for example in Lanza de Cristoforis and Musolino (Complex Var Elliptic Equ 58:511–536, 2013; Commun Pure Appl Anal 13:2509–2542, 2014; Math Methods Appl Sci 35:334–349, 2012). Instead, here we consider the case where also the size of the periodicity cell tends to zero. The results in this chapter are based on the work of Lanza de Cristoforis and Musolino (Two-parameter anisotropic homogenization for a Dirichlet problem for the Poisson equation in an unbounded periodically perforated domain. A functional analytic approach, Typewritten manuscript, 2014)

Exercise motives in independent older adults
No full textAims: People report a host of reasons for exercising. Exercise motives is an important area of study because it can provide significant information for understanding and predicting health behaviors.
The aim of the study was to examine which of the six Exercise Motivations Inventory (EMI-2) scales - Health and Fitness (HF), Social/Emotional Benefits (SEB), Weight Management (WM), Stress Management (SM), Enjoyment (E) and Appearance (A) - discriminate three physical activity levels of Inactive, Active, and Sustained Maintainers.
Methods: Three hundred fifty-five older adults (Age=66.1±6.5y) completed EMI-2 and Physical Activity Stage of Change Questionnaire (PASCQ). BMI was also assessed. Age, BMI, PASCQ, and EMI-2 subscales correlation was investigated with Pearson’s r. Two way ANOVA was used to determine whether exercise motives could discriminate among three physical activity level based on PASCQ. For this aims the six stage of change categories were collapsed into three physical activity level groups: Inactives (precontemplation and contemplation), Actives (preparation, action, early maintenance), and Sustained Maintainers (maintenance for longer than one year).
Results: The three activity levels groups show a low correlation with HF and E (r=.18; p<.001 for both); BMI was correlated with WM (r=.30; p=<.001) while Age was negatively correlated with SM and E (r=-.16; p<.001 / r=-.11, p<.05 respectively). Two way ANOVA shows differences among the six EMI-2 subscales (data expressed in mean±s.d.: HF=3.50±1.05; SEB=2.27±1.23; SM=3.13±1.47; WM=3.34±1.41; E=3.63±1.30; A=1.75±1.54; p<.001), and an interaction groups-subscales (p<.001); the two subscales HF and E discriminate the Inactive group vs Active and Sustained Maintainers (p=<.05 ÷ <.001). Results suggest that Enjoyment (E) and Health and Fitness (HF) motives are important for the maintenance of actual activity in independent older adults. Implications for exercise promotion must be studied
Cason di Lanza, Leggere il passato nelle rocce. Le guide del Geoparco della Carnia - 1
No full textSituato circa a metà della strada che congiunge Paularo a Pontebba, il Passo del Cason di Lanza è lo spartiacque tra il Torrente Pontebbana, che scorre a est per gettarsi nel Fella presso Pontebba, e il Rio di Lanza che, unendosi a ovest al Rio Cercevesa presso Ramaz, dà origine al torrente Chiarsò. Secondo la tradizione popolare il nome deriva dalle lance che si rinvenivano, assieme ad altre armi, in quest’area, testimonianze della vittoriosa battaglia che le truppe della Repubblica Veneta, aiutate da volontari friulani, combatterono contro i turchi nell’estate del 1478. La Valle del Rio di Lanza e la testata di quella del Torrente Pontebbana sono una tra le più interessanti aree naturalistiche della Regione. La diversità degli ambienti naturali che caratterizza i dintorni del Cason di Lanza è legata alle particolari condizioni geologiche di queste valli. Antiche rocce formatesi nei mari del Paleozoico affiorano diffusamente e conservano importanti testimonianze della vita che popolava quei mari centinaia di milioni di anni fa: i fossili
Study of the shelf-life of cured cv Tarocco oranges by sensory and physicochemical parameters
No full textPhysical treatments at temperatures > 30 degrees C and RH > 90% (curing) are useful to limit fungal attacks on citrus fruits post-harvest. In order to evaluate the effect of such treatment on the shelf-life of fruits, cv Tarocco oranges were subjected to curing under various time-temperature combinations and then kept at 8 degrees C and 90% RH for 60 days. Sensory and physicochemical parameters were determined for samples (fresh, at the end of curing, after 20, 40 and 60 days). At the end of the trial, no fungal attacks were detected on fruits. Principal component analysis (PCA) showed differences between fresh and 60 day stored samples. Damage on fruits was proportional to the heat damage of curing. Sensory and physicochemical variables provided different information. The former discriminate samples along the first PC, where the descriptors juiciness, acid and aroma are associated with fresh. Colour differences Delta E, Hunter's parameter a (red-green component) and acidity discriminate samples along the second P
Measurement of physical fitness in anorexia nervosa inpatients with adapted Eurofit battery test
No full textAims. To investigate the effects if inpatient cognitive behavioral therapy (CBT) on physical fitness of patients with Anorexia Nervosa (AN) and to evaluate the feasibility of the Eurofit Battery test (EB) in this population.
Methods: Physical fitness was assessed with an adapted version of the EB (Endurance: 6’ walking test; Arm strength: hand grip; Abdominal: sit up; Leg strength: standing broad jump; Balance: flamingo balance; Flexibility: sit and reach) administered to 29 female AN patients (BMI: 14.35±1.51 kg/m2), pre and post treatment, and to fifty-eight healthy females (BMI: 21.17±2.57 kg/m2) of the same age (24.4±9.2 vs 25.9±9.1ys, respectively, z=1.39, p=0.165). AN group underwent test on the second day of the admission and the last week before the hospital discharge.
Results: All Eurofit items showed good feasibility, but some AN patients refused to sustain some tests at the admission. CBT was associated with a significant improvement in BMI (from 14.3±1.5 to 18.8±1.2, Z=4.20, p<0.001) and in 4 out of 6 Eurofit tests (p<0.05) in the AN group. However, both in pre and post, AN patients generally showed lower scores compared to the control group (all p < 0.001) with the exception of sit up score.
Conclusions: Adapted EB can be recommended for evaluating physical fitness parameters in AN patients. Physical fitness is lower in AN patients than in controls both at baseline and after weight restoration. These data suggest the need to associate to the classical inpatient treatment of AN specific therapeutic strategies to improve physical fitness
Evaluation of corneal deformation analyzed with a Scheimpflug based device
No full textPurpose: To evaluate the correlation between corneal biomechanical and morphological data in healthy eyes. Methods: A complete clinical eye examination of naïve eyes was followed by tomographic (Pentacam, Oculus, Wetzlar, Germany) and biomechanical (Corvis ST, Oculus, Wetzlar, Germany) evaluation. Linear regression between central corneal thickness (CCT), corneal volume (CV) and anterior corneal curvature measured with Sim'K (SK), versus corneal deformation parameters measured with Corvis ST have been run using SPSS software version 18.0. Results: Seventy-six eyes of 76 healthy subjects (44 women and 32 men) with a mean age of 36.84±10.74 years and a mean refractive error of -0.55±1.68D (measured as spherical equivalent) were evaluated. Corneal deformation parameters were weakly correlated with corneal morphological parameters and with spherical equivalent. Although the correlations between deformation amplitude versus SK and between SK versus Velocity of Applanation 2, were higher than the others (R2=0.28 and 0.26 respectively), none of them was statistically significant (p>0.01). Conclusions: According with these findings, Corvis ST seems to be able to provide an analysis of corneal deformation independent from corneal morphological characteristics. If these data will be confirmed in further studies, this device could be useful in the management and screening of eyes with corneal diseases
Effects of a new packaging on the shelf-life of almond cookies
No full textTo prolong the shelf-life of almond cookies the AA have proceeded to the packaging of the product (with and without sugar in surface) in polistyrene/poliethylene settled with flexible film in air and modified atmosphere. During the conservation period (50 days) physical-chemical, micro-biological, and sensorial controls have been carried out. The analysis of the Principal Components has underlined the difference between samples with and on the basis of the first 2 PC positively correlated with the sensorial parameters and negatively with the rheological softness. According to discriminant analysis the 62% of samples were correctly classified
