Tax Evasion: Part of the Underground Economy in Romania
2020
The economies of developed or emerging countries have a component not subject to the eyes of the authorities, the underground economy, the size of which is likely to produce many imbalances and inequities. The attempt to mitigate state revenues by exploiting legislative imperfections or by using ingenious methods to avoid the payment of taxes is called tax evasion. The weight of the underground economy in Romania’s GDP is significant, with the percentage ranging from 22.4% to 28.4%. The European Union average is 10 p.p. lower than the level at which Romania is located, at the opposite end being Austria, Luxembourg and the Netherlands. The underground economy is predominantly dominated by bl…
Spinodal lines and Flory-Huggins free-energies for solutions of human hemoglobins HbS and HbA
1991
Gelation of deoxygenated solutions of sickle-cell human Hemoglobin (HbS) is of high theoretical interest and it has serious pathological consequences. For this reason HbS is probably the most studied protein capable of self-organization. This notwithstanding, the location in the T, c plane of the region of thermodynamic instability of solutions of deoxy-HbS (as bounded by the spinodal line and as distinct from the gelation region) has remained unknown, along with related values of Flory-Huggins enthalpies and entropies. In the present work this information is derived from experiments for the two cases of (deoxy) HbS and of human adult hemoglobin (HbA). Experiments also show critical exponen…
Discussing Eurocentric evaluative epistemic hegemony: an exploratory approach
2017
En el presente artículo pretendo, de una forma aún exploratoria, reunir algunos presupuestos de las teorías poscoloniales/descoloniales para elaborar un pensamiento crítico sobre la hegemonía de determinadas políticas, procesos e instrumentos de evaluación (o de medición educativa), que son claramente eurocéntricos (o euroamericanos) y que integran la actual agenda educativa global. Sin pretender contribuir para subsanar cualquier posible laguna pero reconociendo que, a pesar de las conocidas excepciones, el campo de las políticas de evaluación se encuentra relativamente saturado por abordajes repetitivos y previsibles, me resulta llamativa la capacidad hermenéutica de los presupuestos posc…
Hyperspectral imaging in perfusion and wound diagnostics – methods and algorithms for the determination of tissue parameters
2018
Abstract Blood perfusion is the supply of tissue with blood, and oxygen is a key factor in the field of minor and major wound healing. Reduced perfusion of a wound bed or transplant often causes various complications. Reliable methods for an objective evaluation of perfusion status are still lacking, and insufficient perfusion may remain undiscovered, resulting in chronic processes and failing transplants. Hyperspectral imaging (HSI) represents a novel method with increasing importance for clinical practice. Therefore, methods, software and algorithms for a new HSI system are presented which can be used to observe tissue oxygenation and other parameters that are of importance in supervising…
EXPLORING THE EFFECTS OF DISCUSSION AND TEXT PLANNING STRATEGIES TO ENHANCE AND ASSESS WRITTEN COMMUNICATION SKILLS
2016
A scuola come nella vita, le capacità di comunicazione scritta sono fondamentali. Queste abilità riguardano soprattutto la costruzione di testi per usi e scopi diversi, l’elaborazione efficace delle informazioni, l’uso corretto della forma linguistica. Scrivere significa conoscere le regole grammaticali ma soprattutto riflettere sulle situazioni e sui contesti specifici di realizzazione, considerare le funzioni linguistiche, gli scopi e i bisogni comunicativi. Sempre più spesso lo sviluppo tecnologico alimenta le difficoltà di bambini e ragazzi di produrre discorsi corretti, coerenti e logicamente organizzati. Per promuovere e valutare la competenza espressiva scritta (strutturazione logica…
Análisis litoestratigráfico del keuper urpirenaico central
2004
Joaquin.Bastida@uv.es Se ha estudiado la litoestratigrafía del Keuper surpirenaico central en los afloramientos de dos sectores: las Sierras Marginales (sector sur) y Les Nogueres (sector norte). En el Keuper de las Sierras Marginales se han distinguido tres unidades litológicas: Formación Yesos de Canelles, Formación Yesos de Boix y Formación Arcillas y Carbonatos de Les Avellanes, con una potencia conjunta de 200 a 400 m. En el Keuper de Les Nogueres se han distinguido cuatro unidades litológicas: Formación Arcillas y Carbonatos de Adons, Formación Yesos de Boix, Formación Yesos de Senterada y Formación Arcillas y Carbonatos de Les Avellanes, con una potencia conjunta de más de 200 m. Las…
Definition of a mutual reference shape based on information theory and active contours
2013
In this paper, we propose to consider the estimation of a reference shape from a set of different segmentation results using both active contours and information theory. The reference shape is then defined as the minimum of a criterion that benefits from both the mutual information and the joint entropy of the input segmentations. This energy criterion is here justified using similarities between information theory quantities and area measures, and presented in a continuous variational framework. This framework brings out some interesting evaluation measures such as the specificity and sensitivity. In order to solve this shape optimization problem, shape derivatives are computed for each te…
Host plant cultivar of the grapevine moth Lobesia botrana affects the life history traits of an egg parasitoid.
2009
6 pages; International audience; The quality and susceptibility of insect eggs for egg parasitoids may be affected by the diet experienced by the females that produce the host eggs. We tested the hypothesis that the host plant fed upon by an herbivore during the larval stages will determine the quality of the eggs laid by the adult for an egg parasitoid. We used the tritrophic system comprising five grape cultivars, the European grapevine moth, Lobesia botrana and the parasitoid Trichogramma evanescens. Parasitoid performance in host eggs of different sizes and originating from five grape cultivars was determined. Overall, egg parasitism was higher on cultivars on which L. botrana laid larg…

CARTOGRAPHY OF AGROCLIMATIC INDICES AT MESOSCALE LEVEL: METHODOLOGY AND CASE STUDY OF BORDEAUX WINEGROWING AREA. Implications on vine development and…
2007
Climate spatial variability knowledge is essential in agronomy and forestry, in order to characterize production potential or to assess pest development risks. In viticulture, climate mainly governs grapevine development rate and berry ripening. The aim of the present work is to characterise climate spatial variability at mesoscale level, using several spatialization techniques at daily time step, applied to climate variables and agroclimatic indices, in order to evaluate its consequences on grapevine development and grape ripening. This study was led in the Bordeaux winegrowing region. Six variables were studied: minimum and maximum temperatures, solar radiation, reference evapotranspirati…
