Espace de Minkowski-Lorentz et des sphères : un état de l'art
2016
International audience; Dans cet article, nous faisons une présentation de l'espace de Minkowski-Lorentz généralisant, à Ê 5 l'espace utilisé dans la théorie de la relativité. Cet espace de dimension 5 contient un paraboloïde de dimension 3 et isométrique à l'espace affine euclidien usuel E 3 , l'ensembles des sphères et plans orientés de E 3 regroupés sur une pseudo-sphère unité de dimension 4. Une premier avantage de cet espace est l'écriture intuitive d'une sphère qui est caractérisée par un point, un vecteur normal en ce point et une courbure. Un deuxième avantage est la manipulation de surfaces canal qui sont représentées par des courbes. Un troisième avantage concernant la simplificat…

Hopes and Fears for the Future Among Chinese Adolescents
2014
This study examined the contents of adolescents' hopes and fears for the future in a sample of 1,975 urban and rural 8th, 10th, and 12th graders in China. Chinese adolescents' hopes and fears were most often related to future education, occupation, parental well-being, marriage and family, academics, leisure activities, wealth, interpersonal relationships, collective issues, and self-related issues. Urban adolescents compared to rural ones reported more hopes for education and leisure activities and held fewer hopes and fears for parental well-being and interpersonal relationships. Males reported more hopes and fears for marriage, whereas females reported more hopes and fears for parental w…
Federalismo Fiscale, dinamica della spesa in conto capitale e processi di interazione spaziale: alcune evidenze empiriche
2010
A growing number of countries throughout the world are reconsidering the role and functions of the various levels of government in order to make public policies more effective in meeting the needs of citizens by firmly pursuing administrative devolution. This paper analyses regional interactions in the dynamics of capital public expenditure based on the estimates of a dynamic gravity model (Dendrinos-Sonis,1990) using the database on Italian Regional Public Accounts (RPA) in the 1996-2007 period. This empirical model allows for the analysis of dynamic relations of a horizonal nature (i.e., between various regions) and vertical nature (i.e., between various levels of government) compared to …
Descrizione di una battaglia. Attori e strategie della prova in un processo per femminicidio
2022
Spostando l’attenzione dalla dimensione della verità a quella della veridizione e analizzando la sentenza come una battaglia dialettica che ridefinisce i confini delle identità degli attori coinvolti, il libro propone l’esame di un caso di femminicidio andato in giudizio nel dicembre del 2015. È l’omicidio di una donna che viene insolitamente definito dai giudici come un femminicidio e il cui movente è rinvenuto nel desiderio di possesso dell’omicida nei confronti della vittima. Un caso del quale la cronaca si è poco occupata, anche per il basso livello socio-economico e culturale di vittima e assassino. A renderne ancor più ricca la narrazione, il fatto che di esso (e della giovane vittima…

Strontium and Oxygen Isotope Analyses Reveal Late Cretaceous Shark Teeth in Iron Age Strata in the Southern Levant
2020
Skeletal remains in archaeological strata are often assumed to be of similar ages. Here we show that combined Sr and O isotope analyses can serve as a powerful tool for assessing fish provenance and even for identifying fossil fish teeth in archaeological contexts. For this purpose, we established a reference Sr and O isotope dataset of extant fish teeth from major water bodies in the Southern Levant. Fossil shark teeth were identified within Iron Age cultural layers dating to 8–9th century BCE in the City of David, Jerusalem, although the reason for their presence remains unclear. Their enameloid 87Sr/86Sr and δ18OPO4 values [0.7075 ± 0.0001 (1 SD, n = 7) and 19.6 ± 0.9‰ (1 SD, n = 6), res…
Effects of exposure to a glyphosate-based herbicide on haematological parameters, plasma biochemical indices and the microstructure of selected organ…
2022
Contamination of water environments with herbicides is a common problem nowadays. The aim of the current study was to evaluate the effects of Roundup on common carp ( Cyprinus carpio) after 1, 3 and 10 days of exposure. The used concentrations corresponded to 1 and 5 mg/l of the active ingredient (glyphosate potassium salt). The haematological analysis performed showed a decrease of the RBC count, as well as an increase of the other erythrocyte indices (Hb, MCV, MCH, MCHC). Most of these changes were dependent on the concentration and time. An increase of the WBC count and the percentage of immature neutrophils occurred, thus indicating the presence of inflammation. In the studied blood bio…
Flotsam samples can help explain the δ13C and δ15N values of invertebrate resting stages in lake sediment
2018
Abstract The stable isotopic composition of chitinous remains of Cladocera (water fleas) and freshwater Bryozoa (moss animals) preserved in lake sediment records can provide supporting insights into past environmental and ecosystem changes in lakes. Here we explore whether analyses of these remains isolated from lake flotsam can provide information on the driving variables affecting the isotopic composition of these remains. We collected flotsam in 53 lakes and found enough material in 33 lakes to measure the stable carbon and nitrogen isotope ratios (expressed as δ13C and δ15N values, respectively) of resting stages. These values were compared with lake characteristics, water chemistry mea…
