Institute of Solid-State Physics, University of Latvia as the Centre of Excellence has received funding from the European Union's Horizon 2020 Framework Program H2020-WIDESPREAD-01-2016-2017-TeamingPhase2 under grant agreement No. 739508, project CAMART2.
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.

Transport infrastructures, spillover effects and regional growth: evidence of the Spanish case
2005
The impact of transport infrastructures on the economic growth of both regions and sectors, distinguishing among modes of transport, is analysed. An attempt is also made to capture the spillover effects associated with transport infrastructures. Two different methodologies are used: the first adopts an accounting approach based on a regression on indices of total factor productivity; the second uses econometric estimates of the production function. Very similar elasticities are obtained with both methodologies for the private sector of the economy, both for the aggregate capital stock of transport infrastructures and for the various types of infrastructure. However, the disaggregated result…
L'agriculture urbaine : une agriculture juridiquement comme les autres?
2019
International audience; En plein essor, l'agriculture urbaine se présente comme un défi pour le droit agricole, construit sur un paradigme géographique et sociologique : la ruralité. Dès lors, comment saisir juridiquement ces nouveaux projets productifs, aux formes variées et aux modèles économiques souvent hybrides ? Est-ce aux acteurs urbains de s'adapter à des règles venues d'ailleurs, ou au droit de se tordre pour accompagner le mouvement d'une agriculture des villes, qui questionne celle des champs ?
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.
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…
Reverse electrodialysis heat engine for sustainable power production
2017
Abstract Reverse Electrodialysis Heat Engine (REDHE) is a promising technology to convert waste heat at temperatures lower than 100 °C into electric power. In the present work an overview of the possible regeneration methods is presented and the technological challenges for the development of the RED Heat Engine (REDHE) are identified. The potential of this power production cycle was investigated through a simplified mathematical model. In the first part of the work, several salts were singularly modelled as possible solutes in aqueous solutions feeding the RED unit and the corresponding optimal conditions were recognized via an optimization study. In the second part, three different RED He…
