First volatile inventory for Gorely volcano, Kamchatka
2012
We report here the very first assessment of volatile flux emissions from Gorely, an actively degassing volcano in Kamchatka. Using a variety of in situ and remote sensing techniques, we determined the bulk plume concentrations of major volatiles (H2O 93.5%, CO2, 2.6%, SO2 2.2%, HCl 1.1%, HF 0.3%, H2 0.2%) and trace-halogens (Br, I), therefore estimating a total gas release of 11,000 tons·day−1 during September 2011, at which time the target was non-eruptively degassing at 900°C. Gorely is a typical arc emitter, contributing 0.3% and 1.6% of the total global fluxes from arc volcanism for CO2 and HCl, respectively. We show that Gorely's volcanic gas (H2O/SO2 43, CO2/SO2 1.2, HCl/SO2 0.5) is a…
Considerations Regarding the Public Budget in Romania
2019
The paper presents the etymology, the legal and economic significance, and the structure of the Romanian budgetary system. At the same time, the evolution of the main indicators from 2006-2018 is presented. It is presented, how the budget flows are generated and used, but also the results obtained in the budget years from the aforementioned period. The paper presents the evolution of macroeconomic indicators, which reflect the level, dynamics and structure of budgetary expenditures and revenues. Mostly the objectives of the paper consist of monitoring the evolution of the general consolidated budget and analysing the way of framing the deficit within the maximum limits allowed during the re…
Optimal contract length for biodiversity conservation under conservation budget constraint
2014
We examine the optimal length of a contract period in a conservation program with payments for ecosystem services aiming at protecting biodiversity on privately owned forests. The government chooses the number of stands and the length of contracts so as to maximize biodiversity benefits under a binding conservation budget. We examine the implication of two alternative budgets: a separate budget for each period (periodic budget) or one budget that to be used in all periods (intertemporal budget). The impact of the budget type shows up in the fact that with intertemporal budget choice set is larger and more high quality stands are available for contracting. Based on theoretical characterizati…
Heterogeneity of volatile sources along the Halmahera arc, Indonesia
2021
co-auteur étranger; International audience; The parallel Halmahera and Sangihe arcs in eastern Indonesia are sites of active arc-arc collision of considerable interest in developing understanding of the geodynamics and geochemistry of subduction zones. Owing to the comparative remoteness of the region, few ground-based studies of the volcanoes have been undertaken. Here, we report and integrate gas measurements and (isotope) geochemical analyses of lava samples for Dukono, Ibu, Gamkonora, Gamalama, and Makian volcanoes of the Halmahera arc. Summing gas fluxes for all five volcanoes indicates arcscale emission budgets for H 2 O, CO 2 , SO 2 , H 2 S, and H 2 of 96300±27000, 2093±450, 944±400,…
VALUTAZIONE DELLE PERFORMANCE E ATTIVITÀ DI INDIRIZZO, MONITORAGGIO E CONTROLLO SULLA PROGRAMMAZIONE PUBBLICA REGIONALE DEI FONDI STRUTTURALI. APPROC…
2014
La programmazione pubblica regionale attraversa un momento di forte criticità interna legata al soggetto attuatore regionale, caratterizzata da una lentissima attuazione dei programmi operativi cofinanziati dalla Commissione Europea. In risposta alle emergenze economiche e sociali, l’amministrazione regionale necessita di strumenti in grado di comunicare efficacemente azioni e risultati che possono positivamente influenzare la vita sociale e civile della comunità regionale. In particolare, gli operatori economici e, in generale, tutti i portatori di interesse, basano i propri atteggiamenti e le proprie scelte sulle aspettative delle dinamiche attese nei settori economici e sociali in cui op…
Mercury concentration, speciation and budget in volcanic aquifers: Italy and Guadeloupe (Lesser Antilles)
2009
Abstract Quantifying the contribution of volcanism to global mercury (Hg) emissions is important to understand the pathways and the mechanisms of Hg cycling through the Earth's geochemical reservoirs and to assess its environmental impacts. While previous studies have suggested that degassing volcanoes might contribute importantly to the atmospheric budget of mercury, little is known about the amount and behaviour of Hg in volcanic aquifers. Here we report on detailed investigations of both the content and the speciation of mercury in aquifers of active volcanoes in Italy and Guadeloupe Island (Lesser Antilles). In the studied groundwaters, total Hg (THg) concentrations range from 10 to 500…
Assessing the profitability of investment projects using ordered fuzzy numbers
2019
Background: This article is motivated by the fact that most approaches to capital budgeting are deterministic. In reality, the capital budgeting problem is accompanied by the uncertainty and risk associated with dealing with imprecise data. Taking this uncertainty into account when performing analyses and calculations not only helps to better measure the profitability of investment projects, but also to expand the applicability of capital budgeting methods under real-life or uncertain conditions. The major contribution of this paper is the development of a novel approach to assessing the profitability of an investment project in the presence of uncertainty. Methods: We present a novel appro…
Power system consumption model using SPICE
2014
Space missions have very stringent mass, volume and also power budgets. This requires very precise knowledge of the power consumption of the whole satellite, not only peak power but also static and long term dynamic power. This calculation becomes very complex if all the operational modes (long term dynamic changes) are taken into account, including the different environmental situations. The power budget of any Power Converter Module (PCM), which includes not only the DC/DC converter but also the distribution unit, depends on the power it delivers and on external factors like temperature and input voltage. We propose to use a linear SPICE model using electronic models of discrete component…
STREAMLINING THE BUDGET PROCESS BY PRIORITIZING PUBLIC INVESTMENT PROJECTS
2014
The substantiation of the state budget for 2014 has also considered some measures to improve budget planning activities by prioritizing public investment projects. The prioritizing approach of public investment projects in the budget process is a particularly important and complex one, involving a set of coherent and responsible evaluation, selection and prioritization activities of such projects based on a well defined prioritizing criteria and mechanism. It was started in 2012, unfortunately not as an undertaking of public decision makers in Romania, but as a requirement of the World Bank and International Monetary Fund in order to improve the budget process. The reason is the fact that n…
Functional spatial contextualisation of the effects of multiple stressors in marine bivalves
2018
Abstract. Many recent studies have revealed that the majority of environmental stressors experienced by marine organisms (ocean acidification, global warming, hypoxia etc.) occur at the same time and place, and that their interaction may complexly affect a number of ecological processes. Here, we experimentally investigated the effects of pH and hypoxia on the functional and behavioural traits of the mussel Mytilus galloprovincialis, we then simulated the potential effects on growth and reproduction dynamics trough a Dynamic Energy Budget (DEB) model under a multiple stressor scenario. Our simulations showed that hypercapnia had a remarkable effect by reducing the maximal habitat size and r…
