Volcanic Gas Emissions Along the Colombian Arc Segment of the Northern Volcanic Zone (CAS-NVZ): Implications for volcano monitoring and volatile budg…
2019
Studying spatial and temporal trends in volcanic gas compositions and fluxes is crucial both to volcano monitoring and to constrain the origin and recycling efficiency of volatiles at active convergent margins. New volcanic gas compositions and volatile fluxes are here reported for Nevado del Ruiz, Galeras, and Purace, three of the most persistently degassing volcanoes located in the Colombian Arc Segment of the Northern Volcanic Zone. At Nevado del Ruiz, from 2014 to 2017, plume emissions showed an average molar CO2/S-T ratio of 3.9 +/- 1.6 (S-T is total sulfur, S). Contemporary, fumarolic chemistry at Galeras progressively shifted toward low-temperature, S-depleted fumarolic gas discharge…
Lowstand carbonates, highstand sandstones?
2003
The sedimentary facies, sediment dynamics and sequence architecture of modern high-energy shelves in the mid and high latitudes are largely governed by wave abrasion processes. Cool-water carbonates may form there, if the influx and/or net accretion of siliciclastics is kept at a minimum. Little dilution of the carbonate produced in situ is generally promoted by a wide "epicontinental" shelf, subdued topography of the adjacent mainland, the predominance of limestone outcrops, and an arid climate. The aforementioned requirements are rarely met, and thus will automatically lead to the formation of mixed siliciclastic-cool-water carbonates. Such an example is found in the Early to Mid-Miocene …
Diorganotin(IV) complexes ofD-galacturonic acid: solid-state and solution-phase structural study
2003
Three diorganotin(IV) complexes of D-galacturonic acid (H2GalA; R = Me, n-Bu, Ph), two of which are new derivatives (R = Me, Ph), have been synthesized and their solid-state and solution-phase investigated by IR, Mossbauer, 1H, 13C and 119Sn NMR spectroscopy. The FTIR data suggest that H2GalA, in the dialkyltin derivatives, behaves as a dianionic ligand, coordinating the tin(IV) atom through an ester-type carboxylate and deprotonated alcoholic hydroxo groups, whereas a bridging carboxylate occurs in the diphenyltin(IV) complex. Octahedral and trigonal bipyramidal local geometries on tin(IV) atoms are proposed for dialkyltin(IV)GalA and diphenyltin(IV)GalA complexes respectively on the basis…
COVID-19 Pandemic: New Prevention and Protection Measures
2022
As of the end of February 2021, more than 420,000,000 confirmed cases of COVID-19 have been reported worldwide, with 5,856,224 deaths. Transmission of the different genetically engineered variants of SARS-CoV-2, which have been isolated since the beginning of the pandemic, occurs from one infected person to another by the same means: the airborne route, indirect contact, and occasionally the fecal–oral route. Infection is asymptomatic or may present with flulike symptoms such as fever, cough, and mild to moderate and severe respiratory distress, requiring hospitalization and assisted ventilation support. To control the spread of COVID-19, the World Health Organization (WHO) and Centers for …
Grafiskie izteiksmes līdzekļi detektīva galda spēļu dizainā

Latvijas Universitātes Pedagoģijas, psiholoģijas un mākslas fakultātes Mākslas nodaļas Mākslas profesionālā bakalaura studiju programmas 4. kursa studente Jekaterina Fjodorova (Stud. apl. nr. jf17009) diplomdarba “Grafiskie izteiksmes līdzekļi detektīva galda spēļu izstrādē” mērķis ir izveidot detektīva galda spēli pieaugušajiem. Diplomdarbu veido trīs daļas. Teorētiskajā daļā tiek apkopota informācija par galda spēļu vēsturi, par pasaules populārākajām detektīva galda spēlēm un to dizainu. Empīriskajā daļā tiek salīdzinātas 10 populāras un pieprasītas detektīva galda spēles pasaulē un izstrādāta šo spēļu dizaina parauga analīze, kā arī apkopotas atbildes no daļēji strukturētām intervijām. …
Aglutinācijas pēdas latviešu valodā un to saskatīšanas lietderīgums latviešu valodas studijās
2021
Šis diplomdarbs uzrakstīts pēc vairāku praktisku latviešu valodas kursu novadīšanas. Pirms šiem kursiem tika sarakstītas vairāki latviešu valodas mācību līdzekļi, kas tika tulkoti vairākās valodās. Vairākas latviešu valodas parādības šajos mācību līdzekļos aplūkotas tā, ka daudziem latviešu valodas skolotājiem tas var šķist neparasti, tomēr mērķis ir bijis viens – vadīt kursus tā, lai valodas apguvējiem būtu ērti un viegli apgūt un nejaukt daudzās latviešu lietvārdu deklināciju galotnes, kā arī runā un rakstos aktīvi pareizi lietot daudzo dažādo tipu verbus. Šis ir latviešu valodas funkcionālās gramatikas kurss.
Lo scettro alla prefettocrazia: l'indefinita pervasività del sottosistema antimafia delle grandi opere e il caso emblematico della 'filiera'
2013
Il contributo analizza in via critica le disposizioni contenute nel codice antimafia, volte ad apprestare misure di contrasto alla criminalità organizzata. SEbbene tale obiettivo sia pprezzabile, l?a. manifesta perplessità in ordine ad una generalizzazione delle misure di tutela preventiva, con particolare riferimento al caso dell "filiera"
OGLE-2008-BLG-510: first automated real-time detection of a weak microlensing anomaly - brown dwarf or stellar binary?
2012
The microlensing event OGLE-2008-BLG-510 is characterized by an evident asymmetric shape of the peak, promptly detected by the Automated Robotic Terrestrial Exoplanet Microlensing Search (ARTEMiS) system in real time. The skewness of the light curve appears to be compatible both with binary-lens and binary-source models, including the possibility that the lens system consists of an M dwarf orbited by a brown dwarf. The detection of this microlensing anomaly and our analysis demonstrate that: (1) automated real-time detection of weak microlensing anomalies with immediate feedback is feasible, efficient and sensitive, (2) rather common weak features intrinsically come with ambiguities that ar…
Search for anisotropic gravitational-wave backgrounds using data from Advanced LIGO and Advanced Virgo's first three observing runs
2021
We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. For the first time, we include Virgo data in our analysis and run our search with a new efficient pipeline called {\tt PyStoch} on data folded over one sidereal day. We use gravitational-wave radiometry (broadband and narrow band) to produce sky maps of stochastic gravitational-wave backgrounds and to search for gravitational waves from point sources. A spherical harmonic decomposition method is employed to look for gravitational-wave emission from spatially-extended sources. Neither technique found eviden…
Groove Experience: Emotional and Physiological Responses to Groove-Based Music
2009
Theories of music and emotion suggest that subjective affective experience and physiological arousal are elicited by anticipation of musical-structural events. However, little is known about to what extent groove-based music elicits such expectancies, and consequently how it is experienced. Due to the repetitiveness of the groove, it was hypothesised that microtiming in groove might facilitate a type of arousal that is not peak-based, but rather reflects the groove state of listening, which has been conceptualized as a steady mental state in synchronization with the music. An initial qualitative interview study with three groove-based music producers and musicians investigated the subjectiv…
