Komunikācijas kvalitātes sakarības ar vientulības rādītājiem

2019

Pētījuma mērķis bija noskaidrot, vai pastāv sakarības starp komunikācijas kvalitāti un vientulības rādītājiem. Izmantojot Vientulības skalu (The Revised UCLA Loneliness Scale, Russell, Peplau,& Cutrona, 1996)un Komunikācijas mērķu aptauju, kas iekļāva arī jautājumus par komunikācijas kanāliem (ziņa, zvans, tikšanās), tiešsaistes vidē tika izveidota aptauja, kuru aizpildīja recenzenti no Lielbritānijas (n-143). Izmantojot datu apstrādes programmas MS Excel un SPSS 17.0 (Statistical Package for the Social Science), šajā pētījumā tika konstatēts, ka pastāv statistiski nozīmīga negatīva sakarība starp vientulības rādītājiem un augstu komunikācijas kvalitāti. Sakarība raksturojama, kā apgriezta …

Filipsa līknes sakarība Eiropā un Baltijas valstīs: pārmaiņas laika gaitā.

2022

Filipsa līkne ir viens no svarīgākajiem instrumentiem ECB un Eiropas valstu centrālajās bankās. Šī sakarība starp robežizmaksām un inflāciju, tiek pielietota, lai veidotu Eiropas Savienības monetāro politiku. Monetārā politika darbojas ar laika nobīdi, tāpēc ir svarīgi zināt, cik augsta inflācija būs nākotnē. Filipsa līkne ir instruments, ko izmanto šo prognožu iegūšanai. Liela nozīme ir Filipsa līknes slīpumam – jo līkne ir lēzenāka, jo dārgāka kļūst inflācijas stabilizācija centrālajām bankām. Ekonomisti uzskata, ka līkne ir kļuvusi plakana, sakarība starp inflāciju un robežizmaksām ir zudusi, un citi faktori nosaka inflāciju. Darba mērķis ir novērtēt sakarību starp robežizmaksām un inflā…

Genesis of fumarolic emissions as inferred by isotope mass balances: CO 2 and water at Vulcano Island, Italy

2002

We have developed a quantitative model of CO2 and H2O isotopic mixing between magmatic and hydrothermal gases for the fumarolic emissions of the La Fossa crater (Vulcano Island, Italy). On the basis of isotope balance equations, the model takes into account the isotope equilibrium between H2O and CO2 and extends the recent model of chemical and energy two-end-member mixing by Nuccio et al. (1999). As a result, the H2O and CO2 content and the δD, δ18O, and δ13C isotope compositions for both magmatic and hydrothermal end-members have been assessed. Low contributions of meteoric steam, added at a shallow depth, have been also recognized and quantified in the fumaroles throughout the period fro…

Gas emissions from five volcanoes in northern Chile and implications for the volatiles budget of the Central Volcanic Zone

2014

This study performed the first assessment of the volcanic gas output from the Central Volcanic Zone (CVZ) of northern Chile. We present the fluxes and compositions of volcanic gases (H2O, CO2, H2, HCl, HF, and HBr) from five of the most actively degassing volcanoes in this region—Lascar, Lastarria, Putana, Ollague, and San Pedro—obtained during field campaigns in 2012 and 2013. The inferred gas plume compositions for Lascar and Lastarria (CO2/Stot = 0.9–2.2; Stot/HCl = 1.4–3.4) are similar to those obtained in the Southern Volcanic Zone of Chile, suggesting uniform magmatic gas fingerprint throughout the Chilean arc. Combining these compositions with our own UV spectroscopy measurements of …

Forecasting Etna eruptions by real-time observation of volcanic gas composition

2007

It is generally accepted, but not experimentally proven, that a quantitative prediction of volcanic eruptions is possible from the evaluation of volcanic gas data. By discussing the results of two years of real-time observation of H2O, CO2, and SO2 in volcanic gases from Mount Etna volcano, we unambiguously demonstrate that increasing CO2/SO2 ratios can allow detection of the pre-eruptive degassing of rising magmas. Quantitative modeling by the use of a saturation model allows us to relate the pre-eruptive increases of the CO2/SO2 ratio to the refilling of Etna's shallow conduits with CO2-rich deep-reservoir magmas, leading to pressurization and triggering of eruption. The advent of real-ti…

Isotopically (δ13C and δ18O) heavy volcanic plumes from Central Andean volcanoes: a field study

2017

International audience; Stable isotopes of carbon and oxygen in volcanic gases are key tracers of volatile transfer between Earth's interior and atmosphere. Although important, these data are available for few volcanoes because they have traditionally been difficult to obtain and are usually measured on gas samples collected from fumaroles. We present new field measurements of bulk plume composition and stable isotopes (δ13CCO2 and δ18OH2O+CO2) carried out at three northern Chilean volcanoes using MultiGAS and isotope ratio infrared spectroscopy. Carbon and oxygen in magmatic gas plumes of Lastarria and Isluga volcanoes have δ13C in CO2 of +0.76‰ to +0.77‰ (VPDB), similar to slab carbonate;…

First determination of magma-derived gas emissions from Bromo volcano, eastern Java (Indonesia)

2015

The composition and fluxes of volcanic gases released by persistent open-vent degassing at Bromo Volcano, east Java (Indonesia), were characterised in September 2014 from both in-situ Multi-GAS analysis and remote spectroscopic (dual UV camera) measurements of volcanic plume emissions. Our results demonstrate that Bromo volcanic gas is water-rich (H2O/SO2 ratios of 56-160) and has CO2/SO2 (4.1 +/- 0.7) and CO2/S-tot (3.2 +/- 0.7) ratios within the compositional range of other high-temperature magma-derived gases in Indonesia. H-2/H2O and H2S/SO2 ratios constrain a magmatic gas source with minimal temperature of 700 degrees C and oxygen fugacity of 10(-17)-10(-18) bars. UV camera sensing on …

The bridge volcanic LIdar-BILLI: A review of data collection and processing techniques in the Italian most hazardous volcanic areas

2020

Volcanologists have demonstrated that carbon dioxide (CO2) fluxes are precursors of volcanic eruptions. Controlling volcanic gases and, in particular, the CO2 flux, is technically challenging, but we can retrieve useful information from magmatic/geological process studies for the mitigation of volcanic hazards including air traffic security. Existing techniques used to probe volcanic gas fluxes have severe limitations such as the requirement of near-vent in situ measurements, which is unsafe for operators and deleterious for equipment. In order to overcome these limitations, a novel range-resolved DIAL-Lidar (Differential Absorption Light Detection and Ranging) has been developed as part of…
