Sport commitment and adherence: A social-cognitive analysis. (Compromiso deportivo y adherencia: Un análisis cognitivo social).
2011
Abstract Statement of problem: This study aimed to analyse the ability of a model based on achievement motivation and self-determination theories to predict adherence to competitive sport. This model incorporated commitment as predictor of adherence. A prospective study was performed with a sample of 302 handball players aged between 14 and 18 years. Structural equation modelling gave support to the model proposed. It was verified the sequence of relationships between perceptions of coach-created mastery climate, psychological needs, self-determined motivation, commitment, and adherence. The major contribution of the study was to confirm a motivational model of adherence based on social-cog…
Sterol oxidation in ready-to-eat infant foods during storage.
2008
The effect of storage on sterol oxidation of ready-to-eat infant foods was evaluated. Two different flavor (honey -LH- or fruits-LF-) liquid infant foods, prepared with milk and cereals, were stored for 0, 2, 4, 7 and 9 months, at 25ºC. Sterol oxidation products (SOP) were extracted by cold saponification, purified by silica solid-phase and analyzed by gas chromatography (GC) and GC-mass spectrometry. -sitosterol was the most representative sterol, followed by cholesterol and campesterol. No significant differences in the total and single SOP content (0.8-1 mg/kg of product) were observed with respect to storage time and type of sample; the main SOP found was 7-ketositosterol (< …

Resting Energy Expenditure of Master Athletes: Accuracy of Predictive Equations and Primary Determinants
2021
Resting energy expenditure (REE) is determined mainly by fat-free mass (FFM). FFM depends also on daily physical activity. REE normally decreases with increased age due to decreases in FFM and physical activity. Measuring REE is essential for estimating total energy expenditure. As such, there are a number of different equations in use to predict REE. In recent years, an increasing number of older adults continue to participate in competitive sports creating the surge of master athletes. It is currently unclear if these equations developed primarily for the general population are also valid for highly active, older master athletes. Therefore, we tested the validity of six commonly-used equa…
Regular Strength and Sprint Training Counteracts Bone Aging: a 10- year Follow-up in Male Masters Athletes
2021
According to cross-sectional and interventional studies, high-intensity strength and impact-type training provide a powerful osteogenic stimulus even in old age. Longitudinal evidence on the ability of high-intensity training to attenuate age-related bone deterioration is currently lacking, however. This follow-up study assessed the role of continued strength and sprint training on bone aging in 40- to 85-year-old male sprinters (n=69) with long-term training background. pQCT-derived bone structural, strength and densitometric parameters of the distal tibia (5% distal-proximal tibia length) and tibial midshaft (50% length) were assessed at baseline and after 10 years. The groups of well-tra…
Mestieri e competenze nel cantiere di architettura in Sicilia tra Trecento e primo Cinquecento
2016
La documentazione archivistica ha fornito agli studiosi una solida base di dati per ricostruire il quadro delle professionalità operanti nel cantiere di architettura in Sicilia tra la fine del medioevo e il principio dell’età moderna. Un dato certo è innanzitutto l’esistenza di una organizzazione gerarchica che prevedeva almeno tre livelli. Al vertice della piramide si trova la figura del capomastro chiamato a dirigere l’opera e spesso ad assumere un ruolo di tipo “imprenditoriale”. Impegni e responsabilità sono spesso condivisi con un altro maestro, per ragioni di opportunità e per mantenere la libertà di contrarre più impegni lavorativi in contemporanea. Il livello immediatamente inferior…
Transitions from grid-connected to island operation of Smart Microgrids
2019
In this paper a control methodology is presented to perform a bumpless transition from the on-grid to the offgrid of a smart microgrid. The derived controller manages the internal production in order to get to zero the tie-line active and reactive power flows so that the opening of the tie line breaker does not produce significant perturbations. Experimental tests performed on the microgrid built at the Polytechnic University of Bari demonstrated the effectiveness of the proposed control strategy.
Prediction of Disease–lncRNA Associations via Machine Learning and Big Data Approaches
2021
This chapter introduces long non-coding RNAs and their role in the occurrence and progress of diseases. The discovery of novel lncRNA-disease associations may provide valuable input to the understanding of disease mechanisms at the lncRNA level, as well as to the detection of biomarkers for disease diagnosis, treatment, prognosis, and prevention. Unfortunately, due to costs and time complexity, the number of possible disease-related lncRNAs verified by traditional biological experiments is very limited. Computational approaches for the prediction of potential disease-lncRNA associations can effectively decrease the time and cost of biological experiments. We first review the main computatio…
