Volcanic Plume CO2 Flux Measurements at Mount Etna by Mobile Differential Absorption Lidar
2017
Volcanic eruptions are often preceded by precursory increases in the volcanic carbon dioxide (CO2) flux. Unfortunately, the traditional techniques used to measure volcanic CO2 require near-vent, in situ plume measurements that are potentially hazardous for operators and expose instruments to extreme conditions. To overcome these limitations, the project BRIDGE (BRIDging the gap between Gas Emissions and geophysical observations at active volcanoes) received funding from the European Research Council, with the objective to develop a new generation of volcanic gas sensing instruments, including a novel DIAL-Lidar (Differential Absorption Light Detection and Ranging) for remote (e.g., distal) …
Ultraviolet imaging of volcanic plumes: A new paradigm in volcanology
2017
Ultraviolet imaging has been applied in volcanology over the last ten years or so. This provides considerably higher temporal and spatial resolution volcanic gas emission rate data than available previously, enabling the volcanology community to investigate a range of far faster plume degassing processes than achievable hitherto. To date, this has covered rapid oscillations in passive degassing through conduits and lava lakes, as well as puffing and explosions, facilitating exciting connections to be made for the first time between previously rather separate sub-disciplines of volcanology. Firstly, there has been corroboration between geophysical and degassing datasets at â1 Hz, expeditin…
Evolution of Seismicity During a Stalled Episode of Reawakening at Cayambe Volcano, Ecuador
2021
Cayambe Volcano is an ice-capped, 5,790 m high, andesitic-dacitic volcanic complex, located on the equator in the Eastern Cordillera of the Ecuadorian Andes. An eruption at Cayambe would pose considerable hazards to surrounding communities and a nationally significant agricultural industry. Although the only historically documented eruption was in 1785, it remains persistently restless and long-period (LP) seismicity has been consistently observed at the volcano for over 10 years. However, the sparse monitoring network, and complex interactions between the magmatic, hydrothermal, glacial, and tectonic systems, make unrest at Cayambe challenging to interpret. In June 2016 a seismic “crisis” …
Voltammetric determination of platinum in perfusate and blood: Preliminary data on pharmacokinetic study of arterial infusion with oxaliplatin
2012
Abstract Because Platinum Group Elements have found widespread use in catalytic converters in cars and as chemotherapeutic agent, interest in the development of reliable analytical methods is carried out in order to monitor these analita in humans to protect the citizen's health. Considering that information on the levels of many trace elements in biological matrices is scarce and for many non-essential elements, baseline levels in the population, and especially in those particularly exposed to the risk are lacking, in this paper we optimize an analytical method for biological matrices, using a voltammetric technique to measure the concentration of Pt in blood and perfusate. The amount of P…

Kokemuksia vapaaehtoisesta lapsettomuudesta ja sterilisaatiosta -kirjoitusaineisto 2017
2022
Aineisto koostuu vapaaehtoista lapsettomuutta ja sterilisaatiota käsittelevistä kirjoituksista. Kirjoituspyyntöön saivat vastata kaikki itsensä kohderyhmään kuuluvaksi määrittelevät henkilöt. Aineisto on kerätty alun perin pro gradu -tutkielmaan vuonna 2017. Kirjoituskutsun avulla pyrittiin selvittämään mm. sitä, miten päätös vapaaehtoisesta lapsettomuudesta on syntynyt ja millaisia ajatuksia sterilisaatio vastaajissa herättää. Tarkoitus oli saada tietoa myös siitä, miksi sterilisaatioon hakeudutaan ja millaisia vaikutuksia toimenpiteellä on ollut vapaaehtoisesti lapsettomien ihmisten elämään. Haluttiin myös tietää, millaisena tilanteen näkevät ne, jotka toivoisivat toimenpidettä, mutta eiv…
Voluntary Private Investments Role in Pension System in Latvia
2021
Pension systems have become one of the main priorities for the national governments. Developed countries population is getting older by putting the pressure on the state budgets and work age people tax load. The current pension system in Latvia performs according to regulation of state compulsory unfunded pension scheme since 1996 and regulation of the state funded or accumulated pension scheme since 2001. The third pension system pillar is private voluntary pension schemes realized in form of people contributions into pension funds and life insurance policies. Aim of the research – deeper analyses of voluntary private investments as the pension system part and its development challenges in…

De la perception de la voyelle /y/ chez des apprenants polonais du français langue étrangère
2019
International audience; The main objective of this study is to test the perception of the vowel /y/ among the Polish learners of FLE, as it does not exist in their natural vowel system. We defend the hypothesis that optimal perception conditions can make the identification and acquisition of new sounds more intelligible.; L'objectif principal de cette étude est de tester la perception de la voyelle /y/ chez des apprenants polonais du FLE, celle-ci n'existant pas, en effet, dans leur système vocalique naturel. Nous défendons l'hypothèse selon laquelle des conditions de perception optimales peuvent rendre plus nettes, plus intelligibles, la perception et l'acquisition de sons nouveaux.
