Mechanisms of Water Interaction with Pore Systems of Hydrochar and Pyrochar from Poplar Forestry Waste
2014
The aim of this study was to understand the water-surface interactions of two chars obtained by gasification (pyrochar) and hydrothermal carbonization (hydrochar) of a poplar biomass. The two samples revealed different chemical compositions as evidenced by solid state (13)C NMR spectroscopy. In fact, hydrochar resulted in a lignin-like material still containing oxygenated functionalities. Pyrochar was a polyaromatic system in which no heteronuclei were detected. After saturation with water, hydrochar and pyrochar were analyzed by fast field cycling (FFC) NMR relaxometry. Results showed that water movement in hydrochar was mainly confined in very small pores. Conversely, water movement in py…
From cars to bikes : the effect of an intervention providing access to different bike types : a randomized controlled trial
2019
IntroductionWe aimed to investigate whether providing parents with children in kindergarten with access to different bicycle types could influence (i) travel behavior and cycling amount, and (ii) intrinsic motivation for cycling and psychological constructs related to car use.MethodsA randomized, controlled trial was conducted in Southern Norway from September 2017 to June 2018. In total 36 parents were recruited and randomly drawn into an intervention (n = 18) or control group (n = 18). The intervention group was in random order equipped with an e-bike with trailer (n = 6), a cargo (longtail) bike (n = 6) and a traditional bike with trailer (n = 6).ResultsAt follow-up, more participants fr…
Headache attributed to aeroplane travel: the first multicentric survey in a paediatric population affected by primary headaches
2018
BACKGROUND: This multicentric survey investigates the prevalence and characteristics of Airplane Headache in children affected by primary headaches. METHODS: Patients with symptoms of Airplane Headache were recruited from nine Italian Pediatric Headache Centres. Each patient was handed a structured questionnaire which met the ICHD-III criteria. RESULTS: Among 320 children suffering from primary headaches who had flights during their lifetime, 15 (4.7%) had Airplane Headache, with mean age of 12.4 years. Most of the patients were females (80%). The headache was predominantly bilateral (80%) and localized to the frontal area (60%); it was mainly pulsating, and lasted less than 30 min in all c…
MOBIlity assessment with modern TEChnology in older patients’ real-life by the General Practitioner: the MOBITEC-GP study protocol
2019
Abstract Background Mobility limitations in older adults are associated with poor clinical outcomes including higher mortality and disability rates. A decline in mobility (including physical function and life-space) is detectable and should be discovered as early as possible, as it can still be stabilized or even reversed in early stages by targeted interventions. General practitioners (GPs) would be in the ideal position to monitor the mobility of their older patients. However, easy-to-use and valid instruments for GPs to conduct mobility assessment in the real-life practice setting are missing. Modern technologies such as the global positioning system (GPS) and inertial measurement units …
Different neighborhood walkability indexes for active commuting to school are necessary for urban and rural children and adolescents

Alcohol-impaired Walking in 16 Countries: A Theory-Based Investigation.
2021
Alcohol is a global risk factor for road trauma. Although drink driving has received most of the scholarly attention, there is growing evidence of the risks of alcohol-impaired walking. Alcohol-impaired pedestrians are over-represented in fatal crashes compared to non-impaired pedestrians. Additionally, empirical evidence shows that alcohol intoxication impairs road-crossing judgements. Besides some limited early research, much is unknown about the global prevalence and determinants of alcohol-impaired walking. Understanding alcohol-impaired walking will support health promotion initiatives and injury prevention. The present investigation has three aims: (1) compare the prevalence of alcoho…
Towards More Sustainable Sports: Analyzing the Travel Behavior of Adolescent Soccer Players in Southern Norway
2022
Mitigating climate change is a global challenge demanding effort from all sectors, and sports are no exception. While transportation is one of the key issues regarding sustainable sports, the methods by which children and adolescents get to practice have not received much attention. The objectives of this study were, therefore, to present how adolescents in Southern Norway travel to soccer practice and assess how the mode of transportation is related to sex, socioeconomic status, age, ethnicity, and distance from home to practice. Cross-sectional data were collected from 558 adolescent soccer players (398 boys and 190 girls) representing 30 different clubs from settlements of varying rurali…
Weakly supervised alignment of multisensor images
2015
Manifold alignment has become very popular in recent literature. Aligning data distributions prior to product generation is an appealing strategy, since it allows to provide data spaces that are more similar to each other, regardless of the subsequent use of the transformed data. We propose a methodology that finds a common representation among data spaces from different sensors using geographic image correspondences, or semantic ties. To cope with the strong deformations between the data spaces considered, we propose to add nonlineari-ties by expanding the input space with Gaussian Radial Basis Function (RBF) features with respect to the centroids of a partitioning of the data. Such featur…
Pero Tafur y Bertrandon de la Broquière en Constantinopla : la imagen ceremonial de María de Trebisonda y los encuentros diplomáticos en torno al con…
2018
Tras la caída de Constantinopla (1453), Pero Tafur y Bertrandon de La Broquière difunden sus libros de viajes, dos de los más importantes europeos escritos en el siglo XV. Ambos habían conocido, entre quince y veinte años antes, al emperador de Grecia, Juan VIII Paleólogo, al Papa Eugenio IV y a otros protagonistas de los concilios de Basilea (1431-1434) y Ferrara-Florencia (1438-1439), que decretaron la unión entre las iglesias romana y griega. Los viajeros fueron, así, testigos, pero también informantes y diplomáticos activos para los intentos de unión religiosa y política, que trató de reavivar el Papa Pio II tras la caída de Constantinopla (1453). Tafur y La Broquière conocieron en Cons…
