On FE-grid relocation in solving unilateral boundary value problems by FEM
1992
We consider FE-grid optimization in elliptic unilateral boundary value problems. The criterion used in grid optimization is the total potential energy of the system. It is shown that minimization of this cost functional means a decrease of the discretization error or a better approximation of the unilateral boundary conditions, Design sensitivity analysis is given with respect to the movement of nodal points. Numerical results for the Dirichlet-Signorini problem for the Laplace equation and the plane elasticity problem with unilateral boundary conditions are given. In plane elasticity we consider problems with and without friction. peerReviewed
A review of methods to assess connectivity and dispersal between fish populations in the Mediterranean Sea
2013
Fish populations are linked to each other via dispersal of individuals as eggs, larvae, juveniles or adults. The understanding of this process, known as connectivity, has a pivotal role for the management of overexploited fish stocks and the development of accurate conservation strategies. Knowledge on connectivity and fish movements is considered fundamental toward the correct design of marine protected area (MPA) networks for the achievement of the benefits of protection. Connectivity patterns are still largely unknown worldwide. A general lack of knowledge is particularly evident for the Mediterranean Sea where few studies dealing with this topic have been carried out and some methods, c…
Uztvertais vecāku emocionālais siltums un fiziskās sodīšanas pieredze bērnībā un tās saistības ar depresijas un trauksmes simptomiem pieaugušo vecumā
2021
Pētījuma mērķis bija izpētīt saistību starp bērnībā piedzīvotu fizisko sodīšanu, uztverto vecāku emocionālo siltumu un trauksmes un depresijas simptomiem pieaugušo vecumā, kā arī noteikt, vai uztvertais vecāku emocionālais siltums bērnībā darbojas kā mediators starp bērnībā piedzīvoto fiziskās sodīšanas pieredzi un depresijas un trauksmes simptomiem pieaugušo vecumā. Pētījumā piedalījās 93 respondenti vecumā 18-63 gadiem (M=35,62). Pētījums ir neeksperimentāls, korelatīvi aprakstošs. Instrumentārijs iekļauj 4 aptaujas: Depresijas, Trauksmes un Stresa Skala (Depression Anxiety Stress Scales, Lovibond, S.H. & Lovibond, P.F. 1995); Vecāku attieksmes aptauja (Parental Bonding Instrument, /PBI/,…
L'évolution de l'occupation humaine : l'analyse spatiale exploratoire des données.Le problème de l'incertitude et de l'hétérogénéité des données en a…
2011
The analysis of the evolution of the settlement requires a lot of methodological questioning. Despite a frequent use of the spatial analysis methods, few works return to their methodological problems. This article proposes to make a comparison and a discussion around two exploratory statistical methods (the K function of Ripley and the Kernel Density Estimation). It seems that scale, quality and quantity of input data, are three essential parameters to be taken into account so as to lead a spatial analysis in archaeology. In intrinsic way, archaeological data are non homogeneous. For that purpose, our article proposes a multi scalar approach integrating the non homogeneousness character of …

Développement de l'acceptabilité des aliments solides. A partir de quel âge les morceaux sont-ils acceptés par l'enfant sain ?
2019
Les aliments solides sont proposés aux nourrissons vers 4-6 mois, lorsque leurs besoins nutritionnels ne peuvent plus être uniquement assurés par le lait. Ces aliments (fruits, légumes, produits céréaliers…) sont généralement proposés sous forme de purée ou de bouillie. Au fil des mois, les purées sont ensuite remplacées par des textures de plus en plus consistantes et dures, permettant à l'enfant d'apprendre progressivement à manger les aliments de la table familiale. Cet apprentissage est dépendant du développement des capacités masticatoires de l'enfant, particulièrement dynamique dans la petite enfance. En effet, pour accepter un aliment, l'enfant doit être capable de le manger. Si, à l…

Phenol Profiling and Nutraceutical Potential of
2019
In recent years, agricultural and industrial residues have attracted a lot of interest in the recovery of phytochemicals used in the food, pharmaceutical, and cosmetic industries. In this paper, a study on the recovery of phenol compounds from Lycium spp. leaves is presented. Ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) have been used with alcoholic and hydroalcoholic solvents. Methanolic UAE was the most successful technique for extracting phenols from Lycium leaves, and we used on leaves from L. barbarum and L. chinense cultivated in Italy. The extracts were then characterized as regards to the antioxidant properties by in vitro assays and the phenol profil…
Food-Based Dietary Guidelines around the World: A Comparative Analysis to Update AESAN Scientific Committee Dietary Recommendations
2021
Food-Based Dietary Guidelines (FBDG) include dietary recommendations based on food groups according to the general and accepted nutrition principles and current scientific evidence. Adoption of FBDG contributes to the prevention of malnutrition in all its forms, promotes human health, and reduces environmental impact. The present review aims to perform an international comparative analysis of the FBDG adopted in different countries from three different continents (America, Asia, and Europe), with particular reference to the Spanish Food Safety and Nutrition Agency (AESAN, Agencia Española de Seguridad Alimentaria y Nutrición) Scientific Committee dietary recommendations. A total of twelve c…
Reuse of Food Waste and Wastewater as a Source of Polyphenolic Compounds to Use as Food Additives
2020
Abstract The problem of waste and byproducts generated from agro-industrial activities worldwide is an increasing concern in terms of environmental sustainability. In this ambit, the quantity of food wastes—produced in all steps of the whole food chain—is enormous, and it may be forecasted that food waste could amount to more than 120 billion tonnes by 2020. The reuse of food waste and wastewater as source of polyphenolic compounds could be an interesting discussion in this ambit. In fact, polyphenols obtained in this way might be used for food and non-food purposes by means of new, improved, and safe extraction methods. In light of the opportunity represented by the treatment of agro-indus…
