Image Based Modeling Technique for Pavement Distress surveys: a Specific Application to Rutting
2016
Image-based modeling (IBM) is a well-known technique to obtain high quality 3D models based on multi view images. IBM started being used in several applications such as inspection, identification of objects and visualization, due to the user-friendly approach, the low cost and highly automated technique. This paper focuses on the investigation of the potential application of IBM in the diagnosis of road pavement distresses and in particular rutting. Indeed, the evaluation of the rutting distress is a fundamental step to define the whole state of a pavement as demonstrated by the calculation of Present Serviceability Index (PSI). Currently, the permanent deformation is measured monitoring vi…
XMM-Newton survey of the ELAIS-S1 field
2008
The formation and evolution of cosmic structures can be probed by studying the evolution of the luminosity function of the Active Galactic Nuclei (AGNs), galaxies and clusters of galaxies and of the clustering of the X-ray active Universe, compared to the IR-UV active Universe. To this purpose, we have surveyed with XMM-Newton the central ~0.6{deg}^2^ region of the ELAIS-S1 field down to flux limits of ~5.5x10^-16^erg/cm^2^/s (0.5-2keV, soft band, S), ~2x10^-15^erg/cm^2^/s (2-10keV, hard band, H), and ~4x10^-15^erg/cm^2^/s (5-10keV, ultra hard band, HH). We present here the analysis of the XMM-Newton observations, the number counts in different energy bands and the clustering properties of …
Anxiety and pain perception in patients undergoing mandibular autogenous block bone surgery
2020
Background The aim of the present study was to investigate pain perception and anxiety within the context of surgery for the placement of mandibular block bone and to evaluate the causality effect between theses variables. Material and methods A total of 13 patients were recruited for the study and were submitted to mandibular autogenous block bone surgery. Demographic data were collected and the anxiety level was determined using the State-Trait Anxiety Inventory (STAI). The STAI was administered on the day of surgery and on the 14th postoperative day. Pain was determined using the visual analogue scale (VAS) and limitation of daily activities and postoperative symptoms were also reported.…
Personal Gains from Materials in Social Networks
2021
Importance of gains from social networks is analyzed in great extent in many countries by many researchers as social networks are reaching more and more importance. Research methods applied: analysis of scientific publications, survey of social network users on gains from materials in social networks. For evaluations by respondents in survey it was used evaluation scale 1–6 as it is used in grading system in Germany. Survey data results are analyzed by indicators of descriptive statistics – indicators of central tendency or location: arithmetic mean, median, mode and indicator of variability – standard deviation. In the research there were found differences by countries in use of social net…
Dietary fatty acids and recurrence of colorectal adenomas in a European intervention trial.
2008
Epidemiological studies have provided inconsistent data about the role of dietary fatty acids in colorectal cancer, and few studies have addressed their role in colorectal adenoma. The aim of the study was to assess the risk of overall adenoma recurrence associated with dietary consumption of total fat, subtypes of fat, and specific fatty acids (oleic acid, linoleic acid, alpha-linolenic acid). The study sample was composed of 523 patients with confirmed adenomas at the index colonoscopy, 35 to 75 yr old, who completed the European fiber-calcium intervention trial and had an initial dietary assessment using a qualitative and quantitative food questionnaire. The overall 3-yr recurrence rate …
Continent Anal Urinary Diversion in Classic Bladder Exstrophy: 45-Year Experience
2017
Objective To evaluate the long-term outcomes in patients with classic bladder exstrophy and continent anal urinary diversion (CAD) for continence, upper urinary tract status, secondary malignancies, and sexual function. Patients and Methods The medical records of 82 exstrophy patients having undergone CAD in our department between 1970 and 2015 were reviewed. Patients were invited for follow-up examinations and asked to complete validated questionnaires relating to sexual function. Results Thirty-two of 57 eligible patients with a median follow-up of 23.9 years were included in the study. Ninety-seven percent of patients were fully continent during daytime. Upper urinary tract and renal fun…
The awareness and acceptance of anti-COVID 19 vaccination in adolescence
2022
Abstract Background COVID-19 had devastating effects on children’s and adolescents’ life, including neuropsychological impairment, discontinuation of social life and education. Since June 2021, antiCOVID19 vaccination has become available to adolescents in Italy up to 12 years and since December 2021 to children aged more than 5 years. The pediatric population represents a challenging target for vaccination. Aim of the study is to perform a survey among adolescents to explore factors associated with COVID 19 immunization and their perceptions about COVID-19 vaccines. Methods Italian students aged 10–17 years were invited to participate in an anonymous online survey regarding their immunizat…
EXPRESSIONS OF DISCOMFORT IN ADOLESCENTS. CLINICAL REFLECTIONS RESULTING FROM AN EXPLORATORY STUDY OF A GROUP OF STUDENTS
2006
Obiettivo. Considerati la diffusione e l’incremento dei comportamenti aggressivi e violenti, specie quelli che trovano come radicale comune la mancanza di un’effettiva motivazione e l’efferatezza, la nostra ricerca si è posta l’obiettivo di rintracciare gli indicatori e i segni predittivi di tali comportamenti. La letteratura, inoltre, dimostra che gli indicatori e i segni predittivi di maggiore affidabilità sono quelli legati alle invarianti strutturali (per esempio le strategie difensive, la capacità di controllo degli impulsi). Metodi. È stato realizzato, con un piano di ricerca trasversale, uno studio clinico di confronto reclutando un gruppo di adolescenti (26 soggetti di sesso maschil…
Participation in organized sports is associated with decreased likelihood of unhealthy lifestyle habits in adolescents
2018
Adolescence is a pivotal time for investing in both present and future health. Thus, it is important to identify arenas for promoting positive adolescent health behaviors and preventing negative ones. The aim of this study was to investigate the associations between organized sports participation (OSP) and a broad range of lifestyle habits in Norwegian adolescents. A comprehensive survey was completed by 13 269 junior high and high school students in southern Norway. Multivariable binary logistic regression models, adjusted for gender, age, and parental education, were used to investigate the associations between OSP and adolescent substance use, dietary habits, physical activity level, pas…
Young People in the Social World of Physical Activities : Meanings and Barriers
2022
Physical inactivity has become one of the leading risk factors for non-communicable diseases (NCDs) and death worldwide. From the future perspective it is alarming that in the group of young people few meet the recommendations. In this respect, physical activity promotion in general and physical education have challenges and new approaches are needed. In this study, the theoretical framework is based on the physical activity relationship (PAR) approach and the barriers were grouped according to the ecological model. The aim of the study was firstly to present both the meanings and barriers of physical activity in a comprehensive Finnish population of 11–15 year old (n = 2728) and secondly t…
