Composition des dépenses publiques et impacts sur la croissance économique : analyses théoriques et empiriques sur des panels de pays développés, éme…
2016
The economic role of the State has been the subject of much debate both from theoretical and the practical perspectives. The actors of these controversies include the objectors of the efficiency of the public intervention since Smith to the present days, Keynesians and economists of the synthesis. Topics ranging from principle of the invisible hand, tax, expectations, burden of the debt, crowding out effect, public sector production are treated through of such debates. The work explains the breakdown of public spending components and implications for countries at levels development (OECD, BRICS, and WAEMU). The study also indicated that the effects of the public spending and its components …
Economic evaluation of biogas plant size utilizing giant reed
2015
Abstract Amongst energy crops for the production of biomass feedstock for biogas plants, giant reed (Arundo donax L) has been attracting attention in recent years in Italy. Undoubtedly, this is due to its potentially high yield in terms of biomass, low agronomic inputs, as well as for being eligible for European Union energy crop incentives. The aim of this study was to perform an analysis of plant costs considering three macro-categories (biomass, plant installation and transport). Also, we aimed to describe the economic performances of biogas plants, while progressively altering two key variables. Specifically, we considered electrical power capacity (in the 100–999 kW range) and several …
A method for determining the position and size of optimal sequence regions for phylogenetic analysis.
1995
The availability of fast and accurate sequencing procedures along with the use of PCR has led to a proliferation of studies of variability at the molecular level in populations. Nevertheless, it is often impractical to examine long genomic stretches and a large number of individuals at the same time. In order to optimize this kind of study, we suggest a heuristic procedure for detection of the shortest region whose informational content can be considered sufficient for significant phylogenetic reconstruction. The method is based on the comparison of the pairwise genetic distances obtained from a set of sequences of reference to those obtained for different windows of variable size and posit…
