Mechanisms for Translocation of Heavy Metals from Soil to Epigeal Mosses
2011
The mechanisms for translocation of heavy metals from soil to epigeal mosses were investigated. The first mechanism was demonstrated for (137)Cs and involved the uplifting of the pollutant-containing dust from the soil, followed by the local secondary deposition on surfaces of epigeal mosses and epiphytic lichens. The second mechanism involved the diffusion of metal cations from the soil through water wetting the moss into the gametophyte. The mechanism was demonstrated by measuring the electric conductance of wetted gametophytes with single ends immersed in solutions of Cu and Na salts. In addition, the concentrations of Cu and Cd were compared in moss samples exposed to the natural soil a…
Rethinking vineyard ground management to counter soil tillage erosion
2022
Tillage erosion is a relevant process of soil redistribution in sloping arable land, but little research has analysed the effect of shallow tillage on soil erosion in vineyards. The goal of this study was to quantify the soil tillage effect on soil translocation and erosion at the territorial level in a large vineyard area in Sicily. The soil loss and soil erosion tolerance limits were compared to identify the vineyards with a high risk of soil degradation. An alternative management scenario to traditional tillage was proposed to evaluate the effectiveness of the best management practices on soil conservation. The experimental trials were conducted in 14 vineyards with different slopes and …
Senescence and longevity : from physiological mechanisms to evolutionary processes : studies in birds and mammals
2012
There is an incredible diversity of lifespan in the animal kingdom ranging from a few days for small gastrotrichs worms to several hundred of years for some bivalves or tortoises. This amazing diversity has long questioned biology researchers. The growing interest in the phenomenon of aging, mainly due to the increase in life expectancy in humans, has questioned researchers on processes that determine patterns of longevity and ageing. On the one hand, biomedical and biogerontological studies helped describe numerous cellular and physiological mechanisms related to aging. Among these mechanisms, oxidative stress has been identified as playing a major role, through life-time accumulation of d…

Bail d'habitation- Sauf à ce que la sous-location ait été autorisée, les revenus illicites qu'elle génère pour le locataire sont analysés comme des fruits civils de la propriété pouvant être revendiqués par le bailleur dans leur intégralité.- Fondée sur le droit des biens, la solution est entièrement neuve.- Au plan pratique, elle offre aux propriétaires spectateurs de sous-locations un moyen de rétorsion redoutablement efficace : le reversement par le locataire de l'ensemble des sous-loyers perçus.
The embodied sources of purpose expressions in Latin
2016
This chapter examines the phrasal means of encoding the semantic role of purpose in Latin. After discussing the notion of semantic role and its use in cognitive linguistics, we illustrate the conceptual relation between the notional domains of space and causation. On this basis, we analyze the source of purpose expressions in Latin, which are mainly based on direction (bare dative and the allative markers, i.e. ad / in + accusative), but also include prepositional phrases metaphorically derived from location (e.g. per + accusative, prō + ablative, propter + accusative), or metonymically spreading from reason to purpose (as in the case of causal markers such as genitive + causā and gratiā ).
Mapping the global distribution of the freshwater hydrozoan Craspedacusta sowerbii
2021
The invasive freshwater jellyfish Craspedacusta sowerbii (Limnomedusae, Olindiidae) is native to East Asia and since the end of the 19th century, was observed in Europe, then in North America, and across the globe. In recent decades, reports of C. sowerbii have drastically increased in Europe, North and South America, Australia, Asia, and parts of Africa. However, the worldwide distribution of C. sowerbii remains poorly documented due to the lack of information in various aquatic environments. This dataset globalises the occurrences of this species from an extensive literature review and database review. Information extracted from the literature/database were organised and synthesised accor…
VLPZ: The Vehicular Location Privacy Zone
2016
International audience; One of the key challenges in the success of vehicular ad hoc networks (VANETs) is to consider the location privacy of drivers. Although, the pseudonym changing approach is suggested by standardization development organizations such as IEEE and ETSI, the development of an effective pseudonym changing strategy is still an open issue. The existing pseudonym changing strategies are either not effective to protect against the pseudonyms linking attacks or can have a negative impact on the VANETs’ applications. To address these issues, this paper proposes a new pseudonym changing strategy based on the Vehicular Location Privacy Zone (VLPZ), which is a roadside infrastructu…
The Serial Property and Restricted Balanced Contributions in discrete cost sharing problems
2006
We show that the Serial Poperty and Restricted Balanced Contributions characterize the subsidy-free serial cost sharing method (Moulin (1995)) in discrete cost allocation problems.
The affine equivariant sign covariance matrix: asymptotic behavior and efficiencies
2003
We consider the affine equivariant sign covariance matrix (SCM) introduced by Visuri et al. (J. Statist. Plann. Inference 91 (2000) 557). The population SCM is shown to be proportional to the inverse of the regular covariance matrix. The eigenvectors and standardized eigenvalues of the covariance, matrix can thus be derived from the SCM. We also construct an estimate of the covariance and correlation matrix based on the SCM. The influence functions and limiting distributions of the SCM and its eigenvectors and eigenvalues are found. Limiting efficiencies are given in multivariate normal and t-distribution cases. The estimates are highly efficient in the multivariate normal case and perform …
Maximum probability estimators in the case of exponential distribution
1975
In 1966–1969L. Weiss andJ. Wolfowitz developed the theory of „maximum probability” estimators (m.p.e.'s). M.p.e.'s have the property of minimizing the limiting value of the risk (see (2.10).) In the present paper, therfore, after a short description of the new method, a fundamental loss function is introduced, for which—in the so-called regular case—the optimality property of the maximum probability estimators yields the classical result ofR.A. Fisher on the asymptotic efficiency of the maximum likelihood estimator. Thereby it turns out that the m.p.e.'s possess still another important optimality property for this loss function. For the latter the parameters of the exponential distribution—…
