PROFITABILITY A SUBSYSTEM WITHIN THE GENERAL SYSTEM OF ECONOMIC EFFICIENCY FOR AGRICULTURAL EXPLOITATIONS
2013
Under market economy conditions purchasing profitability represents a rule for each and every market player. It represents an essential condition of the existence of economic units. Survival of the enterprise and assuring its profitability are “the first concerns of every skilled leader. They are valid in each and every moment, right from the enterprises foundation. Thus profitability is a tool for decision making regarding internal administration of the economic unit, as well as in relation to external partners. It is the synthetic expression of results of any nature, an index for decision making and entity behaviour.

A Simplified LCA Tool for Solar Heating and Cooling Systems
2016
Abstract This paper presents a user-friendly Life Cycle Assessment tool, which aims to support researchers, designers and decision-makers in evaluating the life cycle energy and environmental advantages related to the use of solar heating and cooling (SHC) systems in substitution of conventional ones, considering specific climatic conditions and building loads. The tool was developed within the Task 48 “Quality Assurance & Support Measures for Solar Cooling Systems”, promoted by the International Energy Agency in the framework of the SHC Programme.

On the use of unmanned aerial systems for environmental monitoring
2018
[EN] Environmental monitoring plays a central role in diagnosing climate and management impacts on natural and agricultural systems; enhancing the understanding of hydrological processes; optimizing the allocation and distribution of water resources; and assessing, forecasting, and even preventing natural disasters. Nowadays, most monitoring and data collection systems are based upon a combination of ground-based measurements, manned airborne sensors, and satellite observations. These data are utilized in describing both small-and large-scale processes, but have spatiotemporal constraints inherent to each respective collection system. Bridging the unique spatial and temporal divides that li…
L’indicible et l’indiciel. Empreinte gustative et trace figurative
2011
International audience; L’image des aliments fait l’objet d’une production éditoriale foisonnante, protéiforme : livres de cuisine, de recettes ; ouvrages sur le goût, la table, la gastronomie, les Chefs, les styles et les cultures alimentaires ; émissions et blogs culinaires ; productions médiatiques et multimédias, artistiques et muséales innombrables . Sans dresser d’inventaire, on voit bien que le sujet fascine, au point d’occuper, voire de saturer, l’espace des publications en tous genres. L’ampleur du phénomène rend toujours plus difficile la marge de différenciation par rapport à tout ce qui est produit sur le marché, notamment en termes d’images. Difficile, en effet, de parler des a…
CONVERSIONS DE FREQUENCE ULTRA LARGE BANDE PAR MELANGE A QUATRE ONDES INTERMODAL EN CASCADE DANS LES FIBRES MULTIMODES
2017
International audience; Nous mettons en évidence des effets de conversion spectrale paramétrique avec des décalages spectraux très importants (~200THz) dans une fibre à gradient d'indice qui, pompée avec une source laser picoseconde à 1064nm, supporte quatre modes de propagation. À travers des études expérimentales, analytiques et numériques détaillées, nous montrons que les multiples raies paramétriques sont générées par un processus en cascade complexe faisant intervenir des mélanges à quatre ondes intermodaux. Les longueurs d'onde paramétriques résultantes s'étendent dans le visible jusqu'à 410nm et dans le proche infrarouge jusqu'à 1355nm. MOTS-CLEFS : dynamique spatio-temporelle ; conv…
Adverse reactions to the injection of face and neck aesthetic filling materials: a systematic review
2022
Adverse reactions, caused during the inflammation and healing process, or even later, can be induced by the injection of dermal filler and can present a variety of clinical and histological characteristics. In this study we aimed to review the adverse reactions associated with the injection of aesthetic filling materials in the face and neck. The review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Studies published that mentioned adverse reactions in patients with aesthetic filling materials in the face or neck were included. Risk of bias was assessed using the Joanna Briggs Institute appraisal tool. After a 2-step selection pro…
Angular Dependency of Hyperspectral Measurements over Wheat Characterized by a Novel UAV Based Goniometer
2015
In this study we present a hyperspectral flying goniometer system, based on a rotary-wing unmanned aerial vehicle (UAV) equipped with a spectrometer mounted on an active gimbal. We show that this approach may be used to collect multiangular hyperspectral data over vegetated environments. The pointing and positioning accuracy are assessed using structure from motion and vary from σ = 1° to 8° in pointing and σ = 0.7 to 0.8 m in positioning. We use a wheat dataset to investigate the influence of angular effects on the NDVI, TCARI and REIP vegetation indices. Angular effects caused significant variations on the indices: NDVI = 0.83–0.95; TCARI = 0.04–0.116; REIP = 729–735 nm. Our analysis high…
