An initial comparative map of copy number variations in the goat (Capra hircus) genome
2010
Abstract Background The goat (Capra hircus) represents one of the most important farm animal species. It is reared in all continents with an estimated world population of about 800 million of animals. Despite its importance, studies on the goat genome are still in their infancy compared to those in other farm animal species. Comparative mapping between cattle and goat showed only a few rearrangements in agreement with the similarity of chromosome banding. We carried out a cross species cattle-goat array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the goat genome analysing animals of different breeds (Saanen, Camosciata delle Alpi,…
Asiakkuudenhallinta ja sen hyödyt sekä haasteet palveluyrityksissä
2015
Asiakkuudenhallinta hyödyttää yrityksen liiketoimintaa useilla eri tavoilla. Jatkuvasti kasvavan palvelusektorin yrityksille se luo paljon lisäarvoa asiakas-suhteiden hallinnan ja kehittämisen muodossa. Tässä kandidaatin tutkielmassa on tarkasteltu asiakkuudenhallinnan hyödyntämistä palveluyrityksissä. Lisäk-si tutkielmassa on arvioitu asiakkuudenhallinnan haasteita ja mahdollisia on-gelmia palveluyrityksissä ja palvelutuotannossa yleisesti. Aluksi on tarkasteltu asiakkuudenhallintaa yleisellä tasolla, määritelty keskeiset käsitteet, kuvattu asiakkuudenhallinnan yleiset vaiheet ja prosessit sekä tarkasteltu asiakkuu-denhallinnan toteuttamisessa hyödynnettäviä tietojärjestelmiä. Seuraavassa …
École : l'inégalité des parcours
1997
International audience; Depuis trente ans, l'accès aux études s'est généralisé : les deux tiers d'une classe d'âge sont bacheliers et accèdent aux études supérieures. Pourtant, les parcours scolaires traduisent encore fortement les différences sociales par le jeu des orientations, par le choix des options et par la valeur du diplôme obtenu.
ECO-design of solar driven systems: A performance comparison between the Italian and the Brazilian context
2013
The paper shows a comparative analysis of the performances of two typologies of solar assisted cooling systems for building applications. In particular, Life Cycle Assessment (LCA) methodology is applied to assess the energy and environmental impacts of solar-assisted, heat-driven chillers and conventional compression chillers driven by grid-connected and stand-alone photovoltaic configurations. LCA is applied in compliance with the international standards of ISO 14040. System boundaries are defined following a “cradle to grave” approach, taking into account all the life-cycle phases including the raw materials supply, the production of the components of the plant, the operation and mainten…
On the limits to the long-period method in classical economics. A note
2001
On a first reading of Theory of Production, Kurz & Salvadori (1995) appear to confine the empirical domain of the long-period models of the classical theory of value and distribution to stationary economies with non-constant returns to scale and to growing economies with constant returns to scale. Such a reading is shown to be untenable since it merges the two levels of exploring the extension of a model and of testing a theoretical hypothesis. Conversely, the way Kurz & Salvadori tackle the problems of price dynamics and returns to scale in growing economies is shown to be compatible with what appears to be Sraffa's (implicit) strategy of research.
Characterisation of clayey raw materials for ceramic manufacture in ancient Sicily
2011
Abstract It is well known that mineralogical, petrographic and chemical analyses can successfully support provenance studies of archaeological ceramics. The characterisation of a ceramic paste, the assessment of its technology of production and its provenance assignment related to a specific production centre or to a geographical and/or compositional space, are all tasks that can be performed even more accurately if the clayey raw materials used in pottery production are also studied. For that reason the identification of the clay deposits exploited in a given ceramic workshop often plays a key role in the archaeometric reconstruction of the production cycle where geology, mineralogy, petro…

De l'orientation en fin de cinquième au fonctionnement du collège
1992
Ce cahier fait suite aux deux cahiers n° 42 et 45 et est consacré à des analyses longitudinales. Les données transversales de démographie scolaire montrent des différenciations sociales importantes dans l'accès à des niveaux identifiés de la scolarité, tels que le baccalauréat ou l'accès à l'enseignement supérieur. Ainsi, pour l'accès au second cycle observe-t-on que la fréquence est de 87 % chez les enfants de cadres supérieurs, contre seulement 32% chez les enfants d'ouvriers. Autant cette perspective transversale est utile autant elle est insuffisante pour identifier selon quel "calendrier" et par quels mécanismes se constituent progressivement ces différenciations.Le cahier vise à appré…
Start-up with or without inoculum? Analysis of an SMBR pilot plant.
2010
This study analysed a submerged membrane bioreactor (SMBR) start-up with the purpose of determining the best conditions to carry it out. In order to do this, a hollow fibre membrane module was installed in a submerged configuration in a pilot aerobic reactor. The experiment was then divided in two phases, lasting 65 days each. During phase 1, the pilot plant was started-up without inoculum of activated sludge and no sludge, withdrawal was performed. Conversely, in phase 2, the MBR pilot plant was started-up with sludge inoculum and the sludge concentration was kept constant. In both phases, the volumetric loading rate applied to the pilot plant was kept constant. The authors analysed the di…
Correction to: a predictive model for women's assisted fecundity before starting the first IVF/ICSI treatment cycle.
2019
PURPOSE: To introduce a prognostic model for women’s assisted fecundity before starting the first IVF/ICSI treatment cycle. METHODS: In contrast to previous predictive models, we analyze two groups of women at the extremes of prognosis. Specifically, 708 infertile women that had either a live birth (LB) event in the first autologous IVF/ICSI cycle (“high-assisted-fecundity women”, n = 458) or did not succeed in having a LB event after completing three autologous IVF/ICSI cycles (“low-assisted-fecundity women”, n = 250). The initial sample of 708 women was split into two sets in order to develop (n = 531) and internally validate (n = 177) a predictive logistic regression model using a forwar…
